Problems to be solved by the utility model

By using the skin health sensor disclosed in patent document 1 together with a cosmetic device to which a cosmetic stimulus such as a current stimulus is applied, it is possible to intensively care for an abnormal portion of the skin surface detected by the skin health sensor with the cosmetic device. However, in the method of using the skin health sensor and the beauty appliance in this order, the position is marked or stored at the time when the skin abnormality is detected by the skin health sensor, and then the position needs to be treated by the beauty appliance, and the total required time including the detection and treatment of the skin abnormality becomes long. Further, if the position of the mark or the storage of the abnormal portion is not clear, a wide range including the periphery of the position has to be cared for, and accordingly, a long time is required for the care.

In the beauty appliance of patent document 2, in the tap mode, a cotton pad impregnated with a cosmetic liquid is attached to a head, and the cosmetic liquid is impregnated into the skin while a positive current is supplied to the skin surface, and visible light is irradiated to the skin surface by an LED to activate fibroblasts in the dermis layer. At this time, the cosmetic liquid may enter the window through a gap between the window opening of the head and the window plate, thereby causing a short-circuit accident or a malfunction.

The purpose of the present invention is to provide a beauty appliance which can detect and care for skin abnormalities at the same time and can therefore significantly shorten the time required for these. Another object of the present invention is to provide a beauty appliance capable of collectively caring for an abnormal portion on the skin surface.

The invention aims to provide a beauty appliance which can reliably prevent cosmetic liquid from immersing into the inside of a skin head, and can eliminate accidents such as short circuit caused by the immersion of the cosmetic liquid.

Means for solving the problems

The present invention is directed to a cosmetic device provided with a skin stimulator 3 which comes into contact with the skin surface and supplies an electric current, and a light source 26 which irradiates the skin surface with light. A light guide 27 that guides light emitted from the light source 26 to the outside of the window opening 35 is disposed between the window opening 35 that opens to the skin stimulator 3 and the light source 26. Further, a gap between the skin stimulator 3 and the light guide 27, which communicates the inside and the outside of the skin stimulator 3 with each other through the window opening 35, is sealed in a watertight manner by the first sealing body 52 disposed between the skin stimulator 3 and the light guide 27.

An irradiation portion 46 that enters the inner surface of the window opening 35 is provided in a protruding manner at the end portion of the light guide 27 on the window opening 35 side, an irradiation surface 48 that irradiates the light emitted from the light source 26 toward the skin surface is provided at the protruding end, a seal holder 51 that sandwiches an annular first seal 52 is formed around the protruding base end of the irradiation portion 46, and the first seal 52 sandwiched between the seal holder 51 and the inner surface of the skin stimulator 3 is received by the peripheral surface of the irradiation portion 46, whereby the displacement movement of the first seal 52 can be restricted.

The effects of the invention are as follows.

The cosmetic device of the present invention includes a skin stimulator 3 having a stimulation surface 3a which is brought into contact with a skin surface and gives stimulation, and a skin abnormality detection unit 88 which optically detects abnormality of the skin surface, and a measurement unit 143 of the skin abnormality detection unit 88 is located inside an outer contour line of the stimulation surface 3 a. According to this cosmetic device, when the stimulation surface 3a is brought into contact with the skin surface, the skin surface can be cared by the skin stimulator 3 while the skin abnormality detection section 88 checks the state of the skin surface by aligning the measurement section 143 with the skin surface. Therefore, compared to a conventional cosmetic method in which a skin health sensor and a cosmetic device are used independently of each other, the time required for detection of skin abnormality and care can be significantly shortened. Furthermore, the position of the abnormal portion on the skin surface can be precisely specified in real time, and the specified abnormal portion can be accurately and intensively treated. Further, by disposing the measurement section 143 in the outer contour line of the stimulation surface 3a, it is possible to detect and care for skin abnormality in the same posture, and it is possible to save labor and time for changing the posture of the beauty appliance and changing hands. In contrast to the present invention, when a skin irritant and a skin abnormality detection unit are disposed at different positions of a cosmetic device, the posture of the cosmetic device is changed and the hands are changed, which takes time and effort when the skin abnormality is detected and the care is changed.

According to the cosmetic device that increases the output of the skin stimulus source 116 when the skin abnormality detection unit 88 detects an abnormality on the skin surface, the detection result of the skin abnormality detection unit 88 can be reflected immediately on the intensity of the skin stimulus, and the detected abnormal portion can be cared for intensively and intensively. Further, since the skin irritation is automatically enhanced at the time of detection of the skin abnormality, it is possible to save labor and time for the user to switch the output of the skin irritation source 116.

According to the beauty appliance which operates the reporter 89 when the skin abnormality detector 88 detects an abnormality on the skin surface, it is possible to immediately report an abnormal portion on the skin surface to the user by sound or the like, and thereby it is possible to promote intensive care of the portion.

If the measuring portion 143 is disposed at the center of the stimulation surface 3a of the skin stimulator 3, the user can accurately identify the abnormal portion on the skin surface, as compared with the case where the measuring portion 143 is provided at the peripheral portion of the stimulation surface 3 a. When the user who has determined that there is a skin abnormality in the portion in contact with the center portion of the stimulation surface 3a leaves the beauty appliance at that position, care can be given to the abnormal portion and its surroundings without omission.

If the skin irritant 3 is formed of an electric conductor and constitutes a skin detection sensor for detecting that the irritant surface 3a is in contact with the skin surface, the contact of the irritant surface 3a with the skin surface can be detected easily and accurately, as compared with the case where the skin detection sensor is formed independently of the skin irritant 3. When the driving state of the skin abnormality detecting unit 88 is controlled based on the detection signal of the skin detection sensor, the skin abnormality detecting unit 88 is not driven uselessly in a state where the stimulation surface 3a is away from the skin surface, and the power consumption of the cosmetic device can be suppressed.

In a state where the user holds the grip portion 101 of the main body casing 1, the head support portion 100 is more likely to enter the field of view of the user than the skin head 2, and is not blocked by the hand of the user as in the grip portion 101. Therefore, if at least a part of the light emitter 117 constituting the notification body 89 is provided on the head support part 100 or the skin head 2, the user can easily visually confirm the light emitter 117, and the user can be reliably notified that the skin abnormality detection part 88 has detected an abnormality on the skin surface.

If the light emitting body 117 is formed in an intermittent or continuous ring shape, the appearance and contour of the beauty appliance can be made more conspicuous in a state where a larger area is illuminated than in a case where a dot-shaped light emitting body 117 is locally arranged. Therefore, the appearance design of the beauty appliance can be improved, and the commercial value thereof can be improved.

According to the beauty appliance in which the light emitting body 117 is positioned inside the outer contour line of the light blocking wall 128 and emits light to the outside of the outer contour line, when the user looks at the stimulation surface 3a of the skin stimulator 3 in front, the light emitting surface of the light emitting body 117 is blocked by the light blocking wall 128 and is not seen by the eyes of the user, and thus only the light emitted by the light emitting body 117 can be reflected to the eyes of the user. Therefore, it is possible to eliminate the glare light from being applied to the eyes of the user, and to form a fantastic atmosphere in which the skin irritant 3 is surrounded by the blurred and soft light, thereby further improving the design of the cosmetic device.

If the report body 89 includes the vibrator 118, it can be reported to the user via the tactile sense that the skin abnormality detection unit 88 has detected an abnormality on the skin surface by the vibration of the vibrator 118. Therefore, even for a user with blindness or a user in a state of eye closure, the presence of skin abnormality can be reliably reported.

The measurement portion on the skin surface is irradiated with the inspection light from the light emitting unit 138, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount, it is determined that the measurement portion is in a normal state, whereas if the light receiving amount is less than the reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the abnormal portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. When the reporter 89 is activated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

The light emitting unit 138 emits the inspection light to the skin surface, and the light receiving unit 139 that receives the reflected light outputs electrical output values such as current and voltage corresponding to the amount of received light. Then, the state of the skin surface is determined by comparing the electrical output value of the light receiving section 139 with a predetermined electrical reference value. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

As for the light amount of the inspection light reflected by the skin surface of the user, the whiter the skin is, the more the skin is, and the darker the skin is, the less the skin is. Therefore, if the average skin color reflected light amount is set as the reference light amount, when a user who is whiter than the average skin color uses a beauty appliance, the reflected light amount is higher than the reference light amount even at an abnormal portion such as a color patch, and the abnormal portion may be erroneously determined to be normal. On the other hand, when the user who is darker than the average skin color uses the cosmetic device, the amount of reflected light is also lower than the reference light amount at the normal portion, and the normal portion may be erroneously determined as abnormal. Therefore, in the present invention, when the amount of light received corresponding to the electrical output value of the light receiving section 139 is larger than the reference light amount indicated by the electrical reference value stored in the storage section 177, the output value is stored in the storage section 177 as a new electrical reference value. Accordingly, the user moves the beauty appliance along the skin surface, and updates the electrical reference value every time the measurement unit 143 is aligned with a whiter skin color portion, thereby setting the electrical reference value based on the whiter skin color portion of the user. As described above, according to the present invention, it is possible to set an appropriate electrical reference value that matches the skin color of the user, and it is possible to accurately detect skin abnormalities such as color spots regardless of the skin color.

The measurement portion on the skin surface is irradiated with the inspection light from the light emitting unit 138, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount, it is determined that the measurement portion is in a normal state, whereas if the light receiving amount is less than the reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. When the light receiving amount of the light receiving unit 139 is higher than the predetermined upper limit reference light amount which is larger than the reference light amount, if it is determined that the measuring unit 143 is present in the obstacle M which is an obstacle to detect the skin, the following disadvantages can be avoided: the obstacle M is mistaken for the skin surface, and the output of the skin stimulus source 116 is controlled based on the mistaken recognition, so that the skin surface cannot be appropriately treated.

The light emitting unit 138 emits the inspection light to the measurement portion on the skin surface, and the light receiving unit 139 that receives the reflected light outputs electrical output values such as current and voltage corresponding to the amount of received light. Then, when the electrical output value of the light receiving unit 139 is equal to or greater than a predetermined electrical reference value, it is determined that the measured portion is in a normal state, and when the electrical output value is lower than the electrical reference value, it is determined that the measured portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. When the electrical output value of the light receiving unit 139 is higher than the predetermined upper electrical reference value that is larger than the electrical reference value, if it is determined that the obstacle M that is an obstacle to the detection of the skin is present in the measurement unit 143, the following disadvantages can be avoided: the obstacle M is mistaken for the skin surface, and the output of the skin stimulus source 116 is controlled based on the mistaken recognition, so that the skin surface cannot be appropriately treated.

If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the abnormal portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion on the skin surface, the portion can be immediately reported to the user, and intensive care of the portion can be promoted.

Since the skin abnormality detection unit 88 cannot measure the skin state in the presence of the obstacle M in the measurement unit 143, stopping the driving of the skin abnormality detection unit 88 in this case can reliably prevent the increase in power consumption caused by the unnecessary continuous driving of the skin abnormality detection unit 88. In this case, when the reporter 89 is activated, it is reported to the user that the obstacle M is present in the measurement section 143 and the skin abnormality detection section 88 cannot function, and the user can be prompted to take appropriate measures such as removing the obstacle M.

The measurement portion on the skin surface is irradiated with the inspection light from the light emitting unit 138, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount, it is determined that the measurement portion is in a normal state, and conversely, if the light receiving amount is less than the reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. When the amount of light received by the light receiving unit 139 is less than a predetermined lower limit reference light amount that is less than the reference light amount, it is determined that the measured unit is not in an abnormal state, and a portion that does not require care (e.g., moles) can be accurately detected, thereby preventing unnecessary care from being performed on the portion.

The light emitting unit 138 emits the inspection light to the measurement portion on the skin surface, and the light receiving unit 139 that receives the reflected light outputs electrical output values such as current and voltage corresponding to the amount of received light. When the electrical output value of the light receiving unit 139 is equal to or greater than a predetermined electrical reference value, it is determined that the measured portion is in a normal state, and when the electrical output value is lower than the electrical reference value, it is determined that the measured portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. When the electrical output value of the light receiving unit 139 is lower than the predetermined lower limit electrical reference value smaller than the electrical reference value, if it is determined that the measured portion is not in an abnormal state, a portion that does not require care (e.g., moles) can be accurately detected, and thus it is possible to prevent unnecessary care from being performed on the portion.

If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

When it is determined that the portion to be measured on the skin surface is not in an abnormal state (e.g., a mole), if the output of the skin stimulus source 116 is attenuated or stopped, it is possible to more reliably prevent unnecessary care of the portion. In this case, when the reporter 89 is activated, it is possible to immediately report to the user that the measured part is not in an abnormal state (e.g., a black mole), and thus to prompt attention so as not to give unnecessary stimulation to the part.

When the light emitting unit 117 and/or the vibrator 118 is operated in a state where the skin irritant 3 applies cosmetic irritation to the skin surface, the user can more reliably recognize that skin irritation is output from the skin irritant 3. Further, according to the configuration in which the operation state of the light emitter 117 and/or the vibrator 118 is changed at the time of detecting the skin abnormality, the light emitter 117 and/or the vibrator 118 can be used not only as the display body showing the output of the skin irritation from the skin irritant 3 but also as the notification body 89 notifying the detection of the skin abnormality, so that the number of components constituting the beauty appliance can be reduced and the cost can be reduced accordingly, as compared with the case where the display body and the notification body 89 are separately provided.

When the illuminance of the light emitter 117 is controlled to be increased and/or the vibration level of the vibrator 118 is controlled to be increased at the time of detecting the skin abnormality, the user can be made to intuitively recognize that the skin abnormality is detected.

The inspection light emitted from the light emitting unit 138 is preferably an electromagnetic wave having a reflectance greatly different between a normal portion and an abnormal portion of the skin surface, that is, an electromagnetic wave easily absorbed by melanin which causes color unevenness or the like. Examples of such electromagnetic waves include violet visible light. When visible light having a peak in the violet wavelength region is used as the inspection light, skin abnormality such as color spots can be detected with higher accuracy than when visible light having a longer wavelength is used. Further, if the inspection light is visible light, the user can clearly recognize that the inspection light is emitted from the light emitting unit 138 without damaging the skin surface.

When ultraviolet light in the UVA region or UVB region is used as the inspection light, skin abnormality such as color spots can be detected with high accuracy equal to or higher than that in the case of using visible light having a peak in the violet wavelength region.

When the inspection light composed of ultraviolet rays is intermittently irradiated, damage to the skin surface can be reduced as compared with the case where the inspection light is continuously irradiated. In general, since the output of the inspection light is extremely weak, the skin surface is not damaged even when the inspection light composed of ultraviolet rays is used, but it is effective to intermittently irradiate the inspection light when the output of the inspection light needs to be enhanced due to structural factors.

When a current for skin stimulation is supplied from the current source 175 to the skin stimulator 3, it is possible to perform a cosmetic treatment that has an effect such as iontophoresis for immersing the cosmetic liquid into the skin surface, including the abnormal portion detected by the skin abnormality detecting unit 88.

When the grip electrode 10 is in contact with the surface of the hand and the stimulation surface 3a of the skin stimulator 3 is in contact with the skin surface, thereby forming a closed loop across the cosmetic device and the human body, the skin stimulator 3 can be caused to function as a skin detection sensor that detects the contact of the stimulation surface 3a with the skin surface. Accordingly, as compared with the case where the skin detection sensor is provided at a different site from the skin irritant 3, it is possible to easily and accurately detect that the irritant surface 3a is in contact with the skin surface. When the closed loop is detected, the current source 175 supplies a current for skin stimulation to the skin stimulator 3, and stops the supply of the skin stimulation current in a state where the closed loop is not formed, that is, in a state where the stimulation surface 3a is away from the skin surface, thereby suppressing the power consumption of the cosmetic device.

When the optical path grooves 150 and 159 for dividing the optical path of the inspection light are formed along the joining surfaces 149 and 158 of the pair of optical path forming members 140 and 141 in a recessed manner, the optical path of the inspection light can be easily and accurately formed only by joining the optical path forming members 140 and 141 to each other at the time of assembling the cosmetic device.

If the second optical path formation member 141 includes the housing portions 147 and 148 of the light emitting portion 138 and the light receiving portion 139, the number of components constituting the skin abnormality detection portion 88 can be reduced compared to a case where a holder for the light emitting portion 138 and the like is prepared independently, and the cost can be reduced accordingly.

When the skin stimulator 3 is heated by the heater 164, the skin surface including the abnormal portion detected by the skin abnormality detection unit 88 can be subjected to the beauty treatment effective for giving the thermal stimulation. If the heater supporting portion 165 supporting the heater 164 is formed in the first optical path forming member 140, the number of components constituting the skin abnormality detecting portion 88 can be reduced as compared with a case where a holder for the heater 164 is prepared separately, and the cost can be reduced accordingly.

If the skin stimulus source 116 is configured to include the current source 175 and the heater 164, it is possible to apply current stimulus and thermal stimulus to the skin surface including the abnormal portion detected by the skin abnormality detection unit 88. Therefore, a plurality of stimulations can be given to the skin surface, and more effective cosmetic treatment can be performed.

When the skin stimulator 3 is vibrated by the vibrator 118, cosmetic treatment effective to apply vibration stimulation to the skin surface including the abnormal portion detected by the skin abnormality detecting unit 88 can be performed. When the skin abnormality detecting unit 88 is sandwiched and fixed by the skin irritant 3 and the vibrator holder 120, the posture of the skin abnormality detecting unit 88 can be stabilized, and the reliability of detection by the skin abnormality detecting unit 88 can be improved.

When substrate 137 supporting light emitting unit 138 and light receiving unit 139 is sandwiched and fixed by skin irritant 3 and vibrator holder 120 together with skin abnormality detection unit 88, the assembly procedure of the beauty appliance can be simplified and the cost can be reduced accordingly, compared to the case where substrate 137 is fixed by a mechanism different from the fixing mechanism of skin abnormality detection unit 88.

If the light incident surface 185 orthogonal to the inspection light is formed on the inner surface of the lens 142 facing the light emitting section 138, the amount of reflection of the inspection light at the light incident surface 185 can be minimized, and the light transmittance of the lens 142 can be improved. This makes it possible to always irradiate the portion to be measured on the skin surface with a sufficient amount of inspection light and to supply a sufficient amount of reflected light to the light receiving unit 139, thereby always accurately determining the skin condition. Further, when the light transmittance of the lens 142 is high, the light output of the light emitting unit 138 may be small when the same amount of test light is irradiated to the measurement area on the skin surface as compared to when the light transmittance is low, and the cost and the power consumption of the light emitting unit 138 can be reduced.

In the contact surface where the lens 142 contacts the light path formation member 140, 141, if the peripheral edge of the recess 184 on the inner surface of the lens 142 is circumscribed with the opening edges of the first light guide passage 188 and the second light guide passage 189 of the light path formation member 140, 141, there is no obstacle to the inspection light, so that the efficiency of using the inspection light can be improved, and the strength of the lens 142 can be improved. In contrast to the present invention, when the periphery of the concave portion 184 of the lens 142 extends toward the light guide paths 188 and 189, part of the inspection light may be blocked by the extending portion. Further, when the peripheral edge of the concave portion 184 is made larger as it is farther from the opening edges of the two light guide paths 188, 189, the strength of the lens 142 may be insufficient.

The beauty appliance of the present invention is provided with a skin stimulator 3 which is in contact with the skin surface and supplies an electric current, and a light source 26 which irradiates the skin surface with light. Further, a light guide 27 is disposed between the window opening 35 opened to the skin stimulator 3 and the light source 26, and light emitted from the light source 26 can be guided by the light guide 27 and irradiated to the outside of the skin stimulator 3. According to such a cosmetic device, when the cosmetic device is used, by turning on the light source 26 in advance, it is possible to perform cosmetic treatment while illuminating the skin surface with the light emitted from the light guide 27. Further, since the gap between the skin irritant 3 and the light guide 27 is sealed in a watertight manner by the first sealing body 52, when the cosmetic treatment is performed by using the cosmetic liquid at the same time, the cosmetic liquid can be reliably prevented from infiltrating into the skin irritant 3, and accidents such as short-circuiting caused by infiltration of the cosmetic liquid can be prevented, thereby improving the safety and reliability of the cosmetic device.

When the first sealing body 52 is sandwiched between the seal holder 51 provided around the projecting base end of the irradiation portion 46 and the inner surface of the skin irritant 3 and the first sealing body 52 is received by the circumferential surface of the irradiation portion 46, the first sealing body 52 can be restricted from moving away in the radial direction. Therefore, even when a drop impact is applied to the skin head 2, the first sealing body 52 does not move in the radial direction, and therefore, the sealing action can always be performed in a stable state, and the cosmetic liquid can be more reliably prevented from entering the skin irritant 3.

When the irradiation surface 48 is located within the thickness range of the window opening 35, when the skin stimulating body 3 is gradually slid along the skin surface to perform the cosmetic treatment, the irradiation surface 48 can be prevented from being unnecessarily strongly pressed against the skin surface, and the skin of the skin stimulating body 3 can be gently and gently contacted. Further, by positioning the irradiation surface 48 within the thickness range of the window opening 35, the irradiation surface 48 can be brought into close contact with the skin surface, and the light emitted from the light source 26 can be effectively irradiated to the skin surface.

When the peripheral edge of the irradiation surface 48 is flush with the skin stimulation surface 3a of the skin stimulator 3 in the state where the light guide 27 is fixed, the skin stimulator 3 can smoothly slide along the skin surface to perform the cosmetic treatment. Further, since the peripheral edge of the irradiation surface 48 is flush with the skin irritation surface 3a, when the cosmetic liquid adhering to the irradiation surface 48 is removed after the cosmetic treatment, the cosmetic liquid does not stay on the inner edge of the window opening 35, and therefore the cosmetic liquid adhering to the irradiation surface 48 can be completely wiped off or reliably washed with water.

When the skin stimulating body 3 is disposed at the projecting end of the head case 16 and the first sealing body 52 disposed between the skin stimulating body 3 and the light guide body 27 is pressed against the skin stimulating body 3 by the light guide body 27 fixed to the main body case 1, the first sealing body 52 can be elastically deformed by merely assembling the light guide body 27 to the main body case 1, and the gap between the skin stimulating body 3 and the light guide body 27 can be sealed, and the light guide body 27 can be assembled to the main body case 1 with less labor and time.

If the second sealing body 36 is disposed between the mounting wall 34 provided on the skin stimulator 3 and the step portion 20 provided on the inner surface of the front opening 19, the mounting wall 34 of the skin stimulator 3 and the second sealing body 36 can be pressed and fixed toward the step portion 20 in a state where the light guide 27 is fixed to the main body housing 1. Further, as described above, by fixing the light guide 27 to the main body case 1, the two sealing bodies 36 and 52 can be sandwiched at the same time to maintain the sealing posture, and the labor and time required for assembly can be saved.

Detailed Description

(embodiment 1) fig. 1 to 13 show a beauty appliance of an embodiment 1 of the present invention. The front-back, left-right, and up-down in this embodiment are based on the intersecting arrows shown in fig. 2 and 3, and the front-back, left-right, and up-down displays indicated in the vicinity of the arrows. In both figures, the beauty appliance includes a vertically long main body case 1 also serving as a handle, and a pair of front and rear skin heads 2, 102 provided at an upper portion of the main body case 1. The main body case 1 is formed in a hollow case shape by a front case 1a and a rear case 1b formed by dividing front and rear. The upper half of the main body casing 1 constitutes a head support 100 that supports the pair of skin heads 2, 102, and the lower half of the main body casing 1 constitutes a handle part 101.

A vertically long control board 7 facing the front wall of the front case 1a and a battery 8 electrically connected to the control board 7 are housed inside the main body case 1. A power switch 103 for power connection, a mode selection switch 104 for switching the driving mode, and a level switching switch 105 for switching the driving strength are mounted on a lower portion of the front surface of the control substrate 7. A switch panel 6 having three switch buttons 106-108 is provided on the front surface of a handle 101 of a main body case 1, and a user can operate corresponding switches 103-105 by pressing the switch buttons 106-108 inward. Further, a mode display unit 109 for displaying a light emission display drive mode and a level display unit 110 for displaying a light emission display drive intensity are mounted on the upper front surface of the control board 7. The display units 109 and 110 are each formed of a plurality of LEDs, and light-transmitting windows facing the LEDs are provided in the front case 1a and the switch panel 6. The user can visually confirm both the display portions 109 and 110 through the light-transmitting windows.

The skin head 102 on the rear side is housed in the head support portion 100 of the main body case 1 with only the rear surface thereof exposed from the rear case 1 b. The peltier element 113 and the heat sink 114 are housed inside the skin head 102, the skin head 102 is joined to the heat absorbing surface of the peltier element 113, and the heat sink 114 is joined to the heat generating surface. The peltier element 113 is connected to the control board 7 via a lead not shown. When a drive current is supplied from the control board 7 to the peltier element 113, the skin head 102 is cooled via the heat absorbing surface thereof, and the heat generating surface of the peltier element 113 is radiated via the heat sink 114. The skin head 102 on the rear side is used in a "cooling mode" for cooling the skin surface of the user.

The beauty appliance of the present embodiment includes, in addition to the above-described "cooling mode", an "ion extraction mode", an "ion introduction mode", and a "skin abnormality detection mode", and uses the front skin head 2 in the three drive modes. The user selects the "ion extraction mode" immediately after the power switch 103 is pressed down and the mode display unit 109 displays that the mode is being selected. When the mode selection switch 104 is pressed from this state, the driving mode is switched in the order of "ion introduction mode", "skin abnormality detection mode", and "cooling mode", and the display of the mode display unit 109 is switched. When the mode selection switch 104 is pressed in the "cooling mode", the operation returns to the "ion extraction mode". In fig. 1, the skin head 2 on the front side is composed of: a head housing 16 formed of a cylindrical plastic molded product; a skin stimulator 3 mounted on the front end of the head case 16; a head display unit (light emitting body) 117 disposed on the outer peripheral surface of the head case 16; a vibrator 118 and a skin abnormality detection unit 88 housed in the head case 16. As described below, the "skin abnormality detection mode" is a drive mode in which the skin abnormality detection unit 88 is driven and ion implantation is performed.

As shown in fig. 1, a circular mounting seat 14 for mounting a head housing 16 is provided on the upper front surface of the front housing 1a, and a coupling cylinder wall 18 fitted into the mounting seat 14 is formed at the rear end of the head housing 16. The head case 16, the front case 1a, and the vibrator holder 120 that supports the vibrator 118 are integrated by two screws 22 screwed from the inner surface of the front case 1a to the coupling cylinder wall 18. In this attached state, the gap between the outer peripheral wall continuous with the mount 14 and the connecting cylinder wall 18 is sealed by the O-ring 23.

A fitting cylinder wall 122 for fitting the skin irritant 3 is formed at the front end of the head housing 16. The skin irritant 3 is formed of a press-formed product of a titanium plate material in a shape of a circular cap, and is integrally formed with the head case 16 by covering the mounting cylinder wall 122 from the front. The outer peripheral surface of the mounting tube wall 122 and the peripheral wall of the skin stimulator 3 facing thereto are formed in a shape slightly tapered toward the front end. An O-ring 123 is disposed on the outer peripheral surface of the mounting cylindrical wall 122, and the O-ring 123 is sandwiched between the mounting cylindrical wall 122 and the skin stimulating body 3 and elastically deformed, thereby sealing the gap between the two walls 122, 3. The head housing 16 includes a cap mounting portion 17 that bulges out in a circumferential manner to the rear side of the mounting cylindrical wall 122. A retainer ring 124 is fitted to the rear end of the skin stimulating body 3 and received by the front wall of the cap fitting portion 17. The skin irritant 3 is fixed to the head housing 16 by bonding the retaining ring 124 to the cap fitting portion 17. In fig. 3, reference numeral 64 denotes an annular holding cap for holding a sheet-like cotton pad (sheet-like body, obstacle) M, and the holding cap 64 is press-fitted into the cap fitting portion 17 to fixedly hold the cotton pad M fitted to the outer surface of the skin irritant 3. Instead of the cotton pad M, other sheet-like bodies that can absorb liquid, for example, a porous body such as a sponge, or a sheet-like body made of paper may be used, and these may be collectively referred to as a liquid-absorbing sheet-like body M.

A head display portion 117 is disposed on the outer peripheral surface of the head housing 16 between the cap mounting portion 17 and the connecting cylindrical wall 18. In fig. 4, the head display unit 117 is constituted by an endless annular light guide ring 126 wound around the outer peripheral surface of the head case 16, and a pair of upper and lower LEDs 127 embedded in the wall surface of the head case 16 and facing the light guide ring 126. The light guide ring 126 is made of polycarbonate resin, acrylic resin, or the like having excellent light diffusion properties, and the light incident from the LED127 is repeatedly reflected by the light guide ring 126, so that the entire light guide ring 126 emits light substantially uniformly. The outer diameter of the light guiding ring 126 is set to be sufficiently smaller than the outer diameter of the cap fitting portion 17. Therefore, in a state where the user is facing the stimulation surface 3a of the front surface of the skin stimulator 3, the light guide ring 126 itself is shielded by the cap fitting portion 17 and is not mapped to the user's eyes, and only the light generated by the light guide ring 126 is mapped to the user's eyes. That is, the cap attachment portion 17 also serves as a light shielding wall 128 for eliminating glare from being irradiated to the eyes of the user.

A vibrator 118 formed of an eccentric motor and a vibrator holder 120 for supporting the vibrator 118 are housed in the rear half of the head housing 16. The vibrator holder 120 is formed of a pair of front and rear divided holders 130 and 131 that cooperatively hold the vibrator 118. Three projections 132 are provided on the rear surface of the front split bracket 130, and the front and rear split brackets 130, 131 are integrated by screwing screws 133 inserted into the rear split bracket 131 into the respective projections 132. As shown in fig. 1, the rear divided bracket 131 is integrally provided with a pair of left and right flange-shaped base portions 134, and both the base portions 134 are fastened and fixed to the seat wall of the mount seat 14 by screws 22 together with the connecting cylinder wall 18 of the head housing 16. The vibrator holder 120 may be an integrally molded product that is not divided into the pair of divided holders 130 and 131.

A skin abnormality detection unit 88 is disposed between the skin stimulator 3 and the vibrator holder 120. In fig. 5, the skin abnormality detection unit 88 is configured by a light emitting element (light emitting unit) 138 and a light receiving element (light receiving unit) 139 attached to the front surface of a substrate 137, a pair of front and rear light path forming bodies 140 and 141 forming a V-shaped light path from the light emitting element 138 to the light receiving element 139, a lens 142 disposed at the center of the front surface of the first light path forming body 140 located on the front side, and the like. A circular window opening 35 for exposing the lens 142 is formed in the center of the stimulation surface 3a of the skin stimulator 3, and the front surface of the lens 142 exposed through the window opening 35 constitutes a measurement portion 143 facing the measurement portion on the skin surface of the user. In the driven state of the skin abnormality detecting unit 88, the light emitting element 138 emits the test light toward the center of the measuring unit 143, and the test light is reflected by the measurement portion in contact with the skin surface of the measuring unit 143 and reaches the light receiving element 139. The lens 142 is formed using polycarbonate having excellent light transmittance as a material.

The second optical path forming body 141 located on the rear side is formed of a plastic molded product integrally including a substantially disc-shaped base plate 145 facing the base plate 137 and a substantially conical tapered portion 146 provided so as to protrude from the center of the front surface of the base plate 145. Receiving holes (receiving portions) 147 and 148 for receiving the light emitting element 138 and the light receiving element 139 are formed in the left and right of the base plate 145, respectively. In order to prevent the elements 138 and 139 from contacting the wall surfaces of the receiving holes 147 and 148, the receiving holes 147 and 148 are formed slightly larger than the elements 138 and 139. The conical surface of the tapered portion 146 constitutes a joint surface 149 to be joined to the first optical path forming body 140, and a pair of left and right optical path grooves 150 and a pair of upper and lower engaging recesses 151 (see fig. 6) parallel to the generatrix are formed recessed in the joint surface 149.

In fig. 4, the first optical path forming body 140 is formed of a plastic molded product integrally including a substantially disc-shaped base plate 153 that is one turn larger than the base plate 145 of the second optical path forming body 141, a columnar portion 154 provided so as to protrude from the center of the rear surface of the base plate 153, a spring shaft 155 provided so as to protrude from the peripheral portion of the rear surface of the base plate 153, and three protrusions 156, and a mortar-shaped tapered hole 157 that receives the tapered portion 146 is formed so as to penetrate the base plate 153 and the central portion of the columnar portion 154. The wall surface of the tapered hole 157 constitutes a joint surface 158 to be joined to the joint surface 149 of the tapered portion 146, and a pair of left and right optical path grooves 159 facing the optical path groove 150 of the tapered portion 146 are formed recessed in the joint surface 158, and a pair of upper and lower engaging protrusions 160 (see fig. 6) to be engaged with the engaging recesses 151 of the tapered portion 146 are provided so as to protrude therefrom. The spring shaft 155 is inserted through a coil spring 161 for energizing the skin stimulator 3, and supports the spring 161.

If the tapered portion 146 of the second optical path forming member 141 is formed in a substantially conical shape and the tapered hole 157 of the first optical path forming member 140 is formed in a mortar shape, the tapered portion 146 can be accommodated in the tapered hole 157 satisfactorily, and the pair of optical path forming members 140 and 141 are less likely to be displaced from each other. In a state where the bonding surfaces 149, 158 of the tapered portion 146 and the tapered hole 157 are bonded to each other, the light path grooves 150, 159 formed in both the bonding surfaces 149, 158 face each other, thereby forming a hollow light path through which the inspection light passes. The engagement between the engaging convex portion 160 and the engaging concave portion 151 restricts relative rotation of the front and rear light path forming members 140 and 141 around the central axis of the tapered portion 146. Further, the rear end surface of the columnar portion 154 is received by the front surface of the base plate 145 of the second optical path forming body 141. The front split holder 130 and the first light path forming body 140 are integrated by screwing the screws 162 inserted into the front split holder 130 into the respective bosses 156, and the two bodies 130 and 140 sandwich the substrate 137 and the second light path forming body 141 from the front and back. The optical path grooves 150 and 159 may be formed only on one of the two joint surfaces 149 and 158.

In fig. 5, a lens hole 163 for accommodating the lens 142 is formed in a recessed manner in the center of the front surface of the base plate 153 of the first optical path forming body 140, and a heater support portion 165 for supporting the heater 164 is formed in a stepped manner so as to surround the lens hole 163. The heater 164 is constituted by a flat film heater, and the rear surface thereof is supported on a heater supporting portion 165. The front surface of the heater 164 is bonded to the inner surface of the skin stimulator 3 via an insulating double-sided tape 166. The skin stimulator 3 and the heater 164 are electrically insulated by the double-sided adhesive tape 166. A temperature sensor (thermistor) 167 for measuring the surface temperature of the heater 164 and a fuse 168 (see fig. 4) for cutting off the supply of current to the heater 164 in the event of an abnormality are embedded in a part of the heater support portion 165.

As enlarged in fig. 5, tapered guide surfaces 171 and 172 each having a narrowed tip are formed in a circumferential manner on the rear surface of the lens 142 and the bottom surface of the lens hole 163 facing thereto. By bringing the lens 142 into close contact with the first optical path formation member 140 in the front-rear direction and joining the guide surfaces 171 and 172, the lens 142 can be positioned vertically, left and right with respect to the optical path formation member 140. The front surface of the peripheral edge of the lens 142 is bonded to the inner surface of the skin stimulator 3 via an elastic double-sided tape 173. The double-sided tape 173 is pressed against the inner surface of the skin irritant 3 by the lens 142, and seals the gap between the lens 142 and the skin irritant 3 in a watertight manner. That is, the double-sided tape 173 serves as both a fixing mechanism for fixing the lens 142 to the skin irritant 3 and a sealing body for performing water sealing. Further, even if the lens 142 is adhesively fixed to the inner surface of the skin irritant 3 only by the double-sided adhesive tape 173, the positional deviation of the lens 142 with respect to the skin irritant 3 can be sufficiently prevented, and the water tightness between the two 3, 142 can be sufficiently ensured, but in the present embodiment, in order to further improve the positional deviation prevention and the water tightness, the following configuration is adopted: the split holder 131 fastened and fixed to the rear side of the head case 16 by the screws 22 presses the lens 142 against the inner surface of the skin irritant 3 via the split holder 130 on the front side and the pair of light path forming members 140, 141, whereby both the members 3, 142 can be brought into close contact with each other more reliably.

An example of an assembly procedure for assembling the skin head 2 to the front case 1a will be described with reference to fig. 7. First, the pair of the light path forming bodies 140 and 141, the substrate 137, and the coil spring 161 are combined, the screw 162 is inserted into the front split bracket 130, and the screw 162 is screwed into the boss 156 of the first light path forming body 140 to fix the front split bracket 130 to the first light path forming body 140, thereby obtaining a first assembly in which the second light path forming body 141 and the substrate 137 are sandwiched from front to back between the two bodies 130 and 140. Next, the vibrator 118 is assembled from the rear to the front split bracket 130, the screws 133 are inserted into the rear split bracket 131, and the screws 133 are screwed into the respective bosses 132 of the front split bracket 130, so that the front and rear split brackets 130 and 131 are integrated, thereby obtaining a second assembly in which the vibrator 118 and the rear split bracket 131 are added to the first assembly.

The resulting second assembly is inserted from the rear into the opening of the front housing 1a surrounded by the fitting seat 14, and the head housing 16, to which the light guide ring 126, the LED127, and the O-ring 23 are fitted in advance, is inserted from the rear into the inside of the outer peripheral wall continuous with the fitting seat 14. In this state, the screw 22 is inserted from the rear into the mount base 14 and the base portion 134 of the rear split bracket 131, and the screw 22 is screwed into the coupling cylinder wall 18 of the head case 16, whereby the second assembly and the head case 16 are fixed to the front case 1 a. Next, the temperature sensor 167, the fuse 168, the heater 164, and the lens 142 are assembled on the front surface of the first light path forming body 140 exposed from the front surface of the head housing 16, and double- sided tapes 166 and 173 are bonded to the front surfaces of the heater 164 and the lens 142. Finally, the skin stimulating body 3 is mounted on the mounting cylindrical wall 122 of the head housing 16, on which the O-ring 123 is previously disposed, and is fixed by the retaining ring 124. The above assembly procedure is merely an example, and various assembly procedures are conceivable, but in any case, the double- sided tapes 166 and 173, the heater 164, the lens 142, the first light path forming body 140, the second light path forming body 141, the substrate 137, and the front divided holder 130 are sandwiched between the skin irritant 3 and the rear divided holder 131 in this order from the front. The lens 142 and the first optical path forming member 140 may be formed of an integrally molded product.

The skin stimulating member 3 is connected to a current source 175 (see fig. 8) mounted on the control board 7 via a coil spring 161 for supplying current and a lead wire (not shown). A handle electrode 10 (see fig. 3) is fixed to the rear surface of the handle portion 101 of the main body case 1, and the handle electrode 10 is also connected to the current source 175 via a lead wire (not shown). The control unit 115 mounted on the control board 7 controls the supply of current from the current source 175 to the skin stimulator 3 and the handle electrode 10. In the "ion extraction mode", a pulse current of positive polarity is supplied to the skin stimulator 3, and a pulse current of negative polarity is supplied to the handle electrode 10. In the "iontophoresis mode" and the "skin abnormality detection mode", a pulse current of negative polarity is supplied to the skin stimulator 3, and a pulse current of positive polarity is supplied to the handle electrode 10. In the present embodiment, the current source 175, the vibrator 118, and the heater 164 constitute the skin stimulus source 116 that gives the skin stimulator 3 physical cosmetic stimuli, i.e., current stimuli, vibration stimuli, and thermal stimuli.

In the "ion extraction mode" and the "ion introduction mode", the treatment can be performed by directly pressing the stimulation surface 3a of the skin stimulator 3 against the skin surface, and the treatment can also be performed by attaching the cotton pad M to the outer surface of the skin stimulator 3 with the holding cap 64 and pressing the cotton pad M against the skin surface. In the case of using the cotton pad M, the cotton pad M may be impregnated with the cosmetic liquid, or the cotton pad M may be pressed against the skin surface to which the cosmetic liquid is directly applied. On the other hand, in the assembled state of the cotton pad M, the cotton pad M is interposed between the skin surface and the measurement portion 143, and therefore the skin condition cannot be measured by the skin abnormality detection portion 88. Therefore, in the case where the operation is switched to the "skin abnormality detection mode" in the state where the cotton pad M is attached, or in the case where the cotton pad M is attached in the selection of the "skin abnormality detection mode", the control of automatically moving to the "iontophoresis mode" is normally performed, which will be described in detail later.

In the "ion extraction mode", the "ion introduction mode", and the "skin abnormality detection mode", the intensity of the pulse current supplied from the current source 175 to the skin stimulator 3 and the handle electrode 10 is switched in three stages, i.e., "weak", "medium", and "strong", every time the user presses the level switch 105. Specifically, in the "ion extraction mode" and the "ion introduction mode", a voltage of 6V is applied to the current source 175 in the "weak" state, a voltage of 8V is applied to the current source 175 in the "medium" state, and a voltage of 10V is applied to the current source 175 in the "strong" state. In the "skin abnormality detection mode", the control unit 115 automatically controls the voltage applied to the current source 175 based on the drive strength set by the user via the level changeover switch 105 and the care level determined based on the detection result of the skin abnormality detection unit 88. In this embodiment, the applied voltage when the drive strength is "weak" and the care level is "1" is set to 6V, the applied voltage when the drive strength is "medium" and the care level is "1" is set to 8V, the applied voltage when the drive strength is "strong" and the care level is "1" is set to 10V, and the applied voltage is set to increase by 1V every time the care level increases by one step in each drive strength. The maximum value of the care level is "5", and the applied voltage at this time is 10V when the driving strength is "weak", 12V when the driving strength is "medium", and 14V when the driving strength is "strong".

The above-described voltage values are merely examples, and it is needless to say that values other than the above-described values can be adopted. The voltage values given below are also the same. It is only an example that the drive strength set by the level changeover switch 105 is set to three stages and the maximum value of the care level based on the detection result of the skin abnormality detection unit 88 is set to "5", and the number of stages and the maximum value different from these may be adopted. In the present embodiment, the intensity of the pulse current is changed by changing the magnitude of the voltage applied to the current source 175 and the magnitude of the peak value of the pulse current supplied from the current source 175, but a method of changing the magnitude of the duty ratio of the pulse current may be adopted instead of this method or in combination with this method.

As shown in fig. 8 and 9, the control unit 115 controls the pulse current supplied from the current source 175 to the skin stimulator 3 and the handle electrode 10, the drive current supplied to the heater 164 and the vibrator 118, the display contents in the display units 109, 110, and 117, and the like, based on input signals from the switches 103 to 105, the temperature sensor 167, and the like. The control unit 115 further includes a timer 176 capable of measuring the drive time of the beauty appliance, and a storage unit 177 storing a reference voltage V0 (an electrical reference value: an electrical output value corresponding to a predetermined reference light amount) to be described later. The light emitting element 138 is formed of a light emitting diode, is connected to the control unit 115 via the regulator 178, and is connected in series to a resistor (e.g., 100 Ω) in the light emitting element 138. The inspection light emitted from the light emitting element 138 is violet visible light and has a peak wavelength of about 400 nm. The light receiving element 139 is formed of a photodiode, and is connected to the control unit 115 via an operational amplifier 179. Specifically, the light receiving element 139 is connected to the inverting input terminal (-) of the operational amplifier 179, and the output terminal of the operational amplifier 179 is connected to the control unit 115.

When a voltage is applied to the light emitting element 138 from the control unit 115 via the regulator 178, the element 138 emits light and emits inspection light toward the skin surface of the user. The inspection light is reflected by the skin surface of the user and then reaches the light receiving element 139. The amount of reflected light at this time varies depending on the skin color of the user, that is, the amount of melanin pigment. Specifically, in the case of a user with a dark skin and a large amount of melanin pigment, the inspection light is absorbed more by the skin surface, and the amount of reflected light is small. In contrast, in the case of a user with white skin and less melanin pigment, the amount of absorption of the inspection light is small, and the amount of reflected light is large. Even when the inspection light is used by the same user, the inspection light is absorbed more and the amount of reflected light is smaller in an abnormal portion such as a color spot due to melanin pigment than in a normal portion without a color spot. The skin abnormality detecting unit 88 of the present embodiment detects skin abnormality such as color spots based on the difference in the amount of reflected light. Since the violet (380 to 430nm) visible light is more easily absorbed by melanin than the other color visible light having a longer wavelength than the violet visible light, the difference in the amount of reflected light after irradiation to the normal portion and the abnormal portion is large, and the capability of detecting the skin abnormality is excellent.

As the inspection light reflected by the skin surface of the user and reaching the light receiving element 139 increases, a larger current flows to the light receiving element 139, and a larger voltage is output from the operational amplifier 179 to the controller 115. The output voltage V can be obtained by a product of the current I flowing through the light receiving element 139 and a resistance R (for example, 50M Ω) disposed in the negative feedback circuit. The control unit 115 compares the output voltage V from the operational amplifier 179 with the reference voltage V0 stored in the storage unit 177, and determines that the output voltage V is normal if the output voltage V is equal to or higher than the reference voltage V0(V ≧ V0), and conversely determines that the output voltage V is abnormal if the output voltage V is lower than the reference voltage V0(V < V0). In the present embodiment, the amplifier circuit is configured such that the output voltage V increases as the current I increases, but conversely, the amplifier circuit may be configured such that the output voltage V decreases as the current I increases.

The reference voltage V0 is a variable that changes according to the skin color of the user, and is set to a voltage that is higher as the color of the normal portion is white, and is set to a voltage that is lower as the color is black. As shown in the flowchart of fig. 10, at the time of starting the beauty appliance used in the "skin abnormality detection mode", the control unit 115 sets the reference voltage V0 to, for example, 1.0V (step S1), and sets the care levels of the current source 175, the heater 164, and the vibrator 118 to "1" (step S2). Here, the voltage value of 1.0V is a value slightly higher than the voltage value (about 0.8V) output from the operational amplifier 179 when the inspection light is irradiated from the light emitting element 138 toward the mole. The treatment level "1" is a treatment level at which current stimulation or the like to be applied to a normal portion of the skin surface is generated.

In the next step S3, a check is made as to whether or not the cotton pad M is attached to the outer surface of the skin irritant 3. Since the cotton pad M is generally white, when the inspection light is irradiated toward the cotton pad M, the amount of reflected light is larger than that when the inspection light is irradiated toward the skin surface. With this structure, the presence or absence of the assembly of the cotton pad M can be determined. Specifically, the output voltage V outputted from the operational amplifier 179 to the control unit 115 is compared with a predetermined maximum voltage VM (upper limit electrical reference value: electrical output value corresponding to a predetermined upper limit reference light amount) (for example, 2.8V), and when the output voltage V is higher than the maximum voltage VM (yes in step S3), it is determined that the cotton pad M is attached to the outer surface of the skin stimulator 3 and the "skin abnormality detection mode" is ended (step S4), and the operation shifts to the normal "ion introduction mode". On the other hand, if the output voltage V is not higher than the maximum voltage VM (no in step S3), it is determined that the cotton pad M is not directly facing the measurement section 143 but the skin surface of the user, and the process proceeds to step S5.

In the next step S5, the output voltage V and the reference voltage V0 are compared. In the initial state where the reference voltage V0 is set to 1.0V, the output voltage V is higher than the reference voltage V0(V > V0) in many cases, and the output voltage V is set as a new reference voltage V0 in the next step S6. In the next step S7, if the care level is set to other than "1", the care level is set to "1", and the process returns to step S3. The user repeatedly updates the reference voltage V0 and sets the reference voltage V0 corresponding to the skin color of the user by moving the cosmetic device along the skin surface in step S6. That is, the output voltage V of the white portion of the skin of the user, that is, the normal portion where there is no color unevenness or the like is set as the final reference voltage V0. The reference voltage V0 stored in the storage unit 177 is reset to an initial value (e.g., 1.0V) each time the power supply of the cosmetic device is turned off.

In step S5, when the output voltage V is equal to the reference voltage V0 (V0), the process proceeds to step S7 by skipping step S6, and if the care level is set to a value other than "1", the care level is set to "1", and the process returns to step S3. On the other hand, in step S5, when the output voltage V is lower than the reference voltage V0(V < V0), the routine proceeds to step S8, where the output voltage V is compared with a predetermined minimum voltage Vm (lower limit electrical reference value: electrical output value corresponding to a predetermined lower limit reference light amount). The minimum voltage Vm is a constant set to 0.8V, which is the same as the output voltage value when the mole is irradiated with the inspection light, and is stored in the storage unit 177 in advance. When the output voltage V is lower than the minimum voltage Vm (yes in step S8), it is determined that the skin stimulator 3 is aligned with a mole that does not require care, the care level of each skin stimulus source 116 is set to "0" or more and "1" or less so as not to apply useless stimulation to the mole (step S9), the output of each skin stimulus source 116 is stopped or attenuated, and the process returns to step S3. A treatment level of "0" refers to a treatment level at which the output of skin stimulus source 116 ceases such that no stimulus is produced at all from skin stimulus source 116. The care levels of the current source 175, the heater 164, and the vibrator 118 may be set independently between "0" and "1" respectively.

In step S8, when the output voltage V is equal to or higher than the minimum voltage Vm (no in step S8), the process proceeds to step S10, and the difference between the reference voltage V0 and the output voltage V is compared with a predetermined constant C. The constant C is a positive number (C > 0) stored in advance in the storage unit 177. If the difference between the reference voltage V0 and the output voltage V is equal to or less than the constant C (yes in step S10), the care level is set to "2" which is stronger than "1" (step S11), and the process returns to step S3. In contrast, if the difference exceeds the constant C (no in step S10), the process proceeds to step S12.

In step S12, the difference between the reference voltage V0 and the output voltage V is compared with a value of 2 times the constant C. In the case where the difference is 2 times or less the constant C (yes in step S12), the care level is set to "3" stronger than "2" (step S13), and the process returns to step S3. On the contrary, if the difference exceeds 2 times the constant C (no in step S12), the process proceeds to step S14, where the difference between the reference voltage V0 and the output voltage V is compared with a value 3 times the constant C. In the case where the difference is 3 times or less the constant C (yes in step S14), the care level is set to "4" which is stronger than "3" (step S15), and the process returns to step S3. In contrast, in the case where the difference exceeds 3 times the constant C (no in step S14), the care level is set to "5" which is stronger than "4" (step S16), and the process returns to step S3.

Summarizing steps S10 to S16, the care level is set to "2" when the difference between the reference voltage V0 and the output voltage V is equal to or less than a constant C (0 < V0-V.ltoreq.C), and the care level is set to "3" when the difference exceeds the constant C by not more than 2 times (C < V0-V.ltoreq.2C). And, the care level is set to "4" when the difference between the reference voltage V0 and the output voltage V exceeds 2 times of the constant C and does not exceed 3 times (2C < V0-V.ltoreq.3C), and is set to "5" when the difference exceeds 3 times of the constant C (3C < V0-V). Further, for example, a variable that changes in accordance with the reference voltage V0 can be used instead of the constant C used in the present embodiment.

As described above, step S9 is a step of stopping or attenuating the output of each skin stimulus source 116 when a black mole is detected (yes in step S8). The attenuation of the output (care level) of the skin stimulus source 116 in the present invention is a concept including not only reduction to the lowest output but also retention to the lowest output in addition to the stop state. That is, in the case where the care level of the skin stimulus source 116 is set to "1" in step S9, if the care level immediately before is "2" or more, the care level is lowered to "1" in step S9, and if the care level immediately before is already "1", the care level is maintained to "1" in step S9, which is referred to as attenuation in the present invention including the above.

When the user holds the grip portion 101 with a hand and contacts the grip electrode 10, and the skin irritant 3 is brought into contact with the skin surface of the face or the like, an electrical closed loop is formed which is constituted by the internal circuit of the beauty appliance connecting the skin irritant 3 and the grip electrode 10 and the human body of the user. The control unit 115 determines whether or not the stimulation surface 3a is in contact with the skin surface based on the presence or absence of the formation of the closed loop. That is, the skin stimulator 3 of the present embodiment functions as a skin detection sensor that detects that the stimulation surface 3a is in contact with the skin surface. The control unit 115 supplies a pulse current for skin stimulation from the current source 175 to the skin stimulator 3 and the handle electrode 10 only in a state where the closed loop is detected, and supplies a drive current to the vibrator 118. Further, the control unit 115 supplies power to the light emitting element 138 to drive the skin abnormality detection unit 88 only in a state where the closed loop is detected, and supplies power to the head display unit 117 to cause the display unit 117 to emit light. In a state where the electrical closed loop is not formed, that is, in a state where the stimulation surface 3a is away from the skin surface, the power consumption of the cosmetic device can be suppressed by stopping the supply of the pulse current for skin stimulation and the drive current of the vibrator 118, the drive of the skin abnormality detection unit 88, and the light emission display of the head display unit 117.

The skin detection sensor may be configured by an optical sensor or the like independent from the skin irritant 3. When the optical sensor is disposed on the stimulation surface 3a of the skin stimulator 3, the stimulation surface 3a comes into contact with the skin surface, and the optical sensor cannot receive indoor light. When this occurs, a signal is transmitted from the optical sensor to the control unit 115, and the control unit 115 that has received the signal determines that the stimulation surface 3a is in contact with the skin surface, and starts supply of the pulse current from the current source 175, driving of the skin abnormality detection unit 88, and the like.

Next, a case where the beauty treatment instrument of the present embodiment is used in the "skin abnormality detection mode" will be described. As described above, the "skin abnormality detection mode" is a drive mode in which the skin abnormality detection unit 88 is driven and ion introduction is performed, and the control unit 115 supplies a pulse current for skin stimulation to the skin stimulator 3 and the handle electrode 10 in addition to driving the skin abnormality detection unit 88, and further drives the heater 164 and the vibrator 118. That is, the current stimulus, the thermal stimulus, and the vibration stimulus are applied to the skin surface while the skin state of the user is detected. When an abnormal portion such as a color spot is detected by the skin abnormality detecting unit 88, the current stimulation or the like is automatically increased at the abnormal portion, and the abnormal portion is cared for intensively and intensively. That is, the care level of the skin stimulus source 116 (current source 175, heater 164, vibrator 118) is set to "1" in the normal portion of the skin surface, and is set to "2" to "5" in the abnormal portion according to the degree of abnormality. In the mole part, the care levels of the skin stimulus sources 116 are set to "0" to "1".

In the timing chart of fig. 11, when the user turns on the power switch 103 and operates the mode selection switch 104 to select the "skin abnormality detection mode" (time t0), the control unit 115 switches the display of the mode display unit 109, starts the counting of the timer 176, and controls the current source 175 so as to start the supply of the weak pulse current for skin detection to the skin stimulator 3 and the grip electrode 10. At the same time, the control unit 115 causes the light emitting element 138 of the skin abnormality detecting unit 88 to light up for a moment (for example, 0.2 second). When the light emitting element 138 is temporarily turned on when the "skin abnormality detection mode" is selected, the user can clearly recognize that the driving mode is switched to the "skin abnormality detection mode" in conjunction with the switching of the display of the mode display unit 109. The light emitting element 138 is turned off after being temporarily turned on, and is turned on again at a time point (a time point t1 described later) when the skin detection state in which the electrically closed loop is formed is achieved. The user cannot confirm that the light emitting element 138 is lit in the skin detection state, i.e., in the state where the skin stimulating body 3 is in contact with the skin surface. The meaning of temporarily lighting the light emitting element 138 when selecting the "skin abnormality detection mode" also includes the meaning of making the user confirm the operation of the light emitting element 138. That is, the user can recognize the light emission state such as the case where the light emitting element 138 is in the normal state and has not failed, the light emission color in the lit state, and the like by the temporary lighting of the light emitting element 138. After about 5 seconds after the power is turned on, the control unit 115 starts the energization of the heater 164 to warm up the skin irritant 3. The care level of the heater 164 at this time is "1". The control unit 115 performs on/off control of the heater 164 so as to maintain the surface temperature of the stimulation surface 3a of the skin stimulator 3 at about 40 ℃ based on the input signal from the temperature sensor 167.

In the cosmetic device of the present embodiment, the drive mode is reset to the "ion extraction mode" every time the power supply is turned off, and the time when the "skin abnormality detection mode" is selected by the mode selection switch 104 after the power supply is turned on is time t0 in the timing chart of fig. 11, but in the cosmetic device in which the drive mode is stored even after the power supply is turned off, when the power supply is turned off in a state in which the "skin abnormality detection mode" is selected, the "skin abnormality detection mode" is selected from the beginning after the power supply is turned on next, and the time when the power supply switch 103 is controlled to be turned on is time t0 in fig. 11. In addition, in the beauty appliance including only the "skin abnormality detection mode" as the drive mode, the time when the power switch 103 is turned on is also time t0 in fig. 11.

When the user holds the grip portion 101 and brings the skin stimulator 3 into contact with the skin surface, the above-described electrical closed loop is formed. The control unit 115 that detects the closed loop starts supply of the pulse current for skin stimulation from the current source 175 to the skin stimulator 3 and the handle electrode 10, supply of the driving current to the vibrator 118, light emission display of the head display unit 117, and irradiation of the inspection light from the light emitting element 138 to the skin surface (time t 1). The care level of the current source 175 and the vibrator 118 at this time is "1", and the care level of the heater 164 is also maintained at "1". The head display unit 117 displays, for example, a blue light, that the care level of the skin stimulus source 116 is "1".

When the care level is "1", the pulse current for skin stimulation supplied to the skin stimulator 3 is weak, and therefore, the user cannot easily recognize that the current is being supplied. Therefore, in the present embodiment, when a pulse current of the care level "1" is supplied, the vibrator 118 and the heater 164 are simultaneously driven, and the head display section 117 is caused to emit light. Since the user can easily recognize that the vibrator 118, the heater 164, and the head display unit 117 are being energized regardless of the care level, the user can recognize that the pulse current of the care level "1" is being supplied by recognizing that these are being energized. That is, the vibrator 118, the heater 164, and the head display unit 117 function as an energization indicator for indicating that the pulse current for skin stimulation is supplied to the skin stimulator 3.

During the period from time t1 to time t4, the reference voltage V0 is updated a plurality of times in accordance with the procedure described in fig. 10. At time t2, the output voltage V on the light receiving side is lower than the reference voltage V0, so that the care level of the skin stimulus source 116 temporarily rises to "2", and at the next time t3, the output voltage V is higher than the reference voltage V0, so that the reference voltage V0 is updated and the care level returns to "1". When the reference voltage V0 is set to 2.4V at time t4, the reference voltage V0 is not updated, and thus it is found that the skin abnormality detection unit 88 faces the whitest portion of the skin of the user at time t 4. Of course, the voltage value of 2.4V is merely an example, and when another user with a different skin color uses the beauty appliance, the reference voltage V0 changes. Even when one user continues to use the cosmetic device, when the part to be treated changes, the reference voltage V0 may change in accordance with the change. Even when one user continues to use the beauty appliance for one part of care, the reference voltage V0 may fluctuate due to the influence of daily living environment and the like.

Immediately before time t5 to time t6, the output voltage V fluctuates between the reference voltage V0(2.4V) and the minimum voltage Vm (0.8V), and the care level of the skin stimulus source 116 fluctuates between "2" and "5". Meanwhile, the head display unit 117 displays the care levels "2" to "5" with different colors of light. For example, green light can be displayed at care level "2", yellow light can be displayed at care level "3", orange light can be displayed at care level "4", and red light can be displayed at care level "5". When light other than blue indicating the care level "1" is displayed on the head display unit 117, it can be reported to the user that the skin abnormality detection unit 88 has detected a skin abnormality. That is, the head display unit 117 of the present embodiment constitutes a report body 89 that reports to the user that the skin abnormality detection unit 88 has detected a skin abnormality. The user can also recognize that the skin abnormality detection unit 88 has detected a skin abnormality by an increase in the treatment level of the vibrator 118, that is, by a case where the vibration and sound of the vibrator 118 become strong. The user can also recognize that the skin abnormality detection unit 88 has detected a skin abnormality by the increase in the care level of the heater 164, that is, by the increase in the surface temperature of the stimulation surface 3 a. That is, the vibrator 118 and the heater 164 constitute not only the skin stimulus source 116 but also the report body 89 together with the head display section 117.

As described above, the vibrator 118, the heater 164, and the head display unit 117 function as an energization indicator of pulse current for skin stimulation. That is, the vibrator 118 and the heater 164 have three functions of the skin stimulus source 116, the reporter 89, and the energization indicator, respectively, and the head display unit 117 has two functions of the reporter 89 and the energization indicator. In contrast to the present embodiment, when the vibrator 118, the heater 164, and the head display unit 117 are stopped when the pulse current of the care level "1" is supplied and the vibrator 118 is driven when the pulse current of the care level "2" or more is supplied, the vibrator 118 and the like cannot be used as the energization indicator, but also functions as the skin stimulus source 116 and the reporter 89.

In the present embodiment, the color of the head display unit 117 is changed according to the change of the care level, but instead, the head display unit 117 may be made monochrome, and the illuminance may be increased stepwise according to the increase of the care level. In this case, the color of the head display unit 117 can be arbitrarily selected from blue, red, green, and the like. Further, a sound generating mechanism such as a buzzer or a synthesized sound may be used instead of or in addition to the light emitting mechanism such as the head display unit 117. In this case, the user can be notified via the auditory sense that the care level has changed by changing the tone of the sound generation mechanism in accordance with the change in the care level or by increasing the sound volume of the sound generation mechanism in stages in accordance with the increase in the care level.

At time t6, the output voltage V on the light receiving side shows 0.8V equal to the minimum voltage Vm. In this case, the control unit 115 determines that the skin abnormality detection unit 88 is facing the mole, sets the care level of the current source 175 and the vibrator 118 to "0" or more and "1" or less, and sets the care level of the heater 164 to "1". Further, the control unit 115 causes the head display unit 117 to blink with an arbitrary color. The user can recognize that the skin abnormality detection unit 88 is facing a mole based on a case where the head display unit 117 switches the blinking display and a case where the vibration and sound of the vibrator 118 are weak. The head display unit 117 in the case of determining a moles can be a color change display in which the color changes every several seconds, or a state of being turned off. In the present embodiment, each skin stimulus source 116 (current source 175, vibrator 118, and heater 164) is also driven when a nevus is determined, but instead of setting at least one treatment level in the skin stimulus sources 116 to "0" when a nevus is determined, the stimulation applied from the skin stimulus sources 116 to the skin surface may be stopped.

At time t7, the user moves the skin stimulator 3 away from the skin surface, and the electrical closed loop disappears, and the control unit 115 that cannot detect the closed loop stops the irradiation of the inspection light from the light emitting element 138, and switches the pulse current supplied from the current source 175 to the skin stimulator 3 and the handle electrode 10 from the pulse current for skin stimulation to the weak pulse current for skin detection. Then, the control unit 115 sets the treatment level of the vibrator 118 to "0", sets the treatment level of the heater 164 to "1", sets the state to a warm-up state, and turns off the head display unit 117. At the next time t8, the control unit 115 detects the electrical closed loop again, and thus starts irradiation of the inspection light from the light emitting element 138 again. When 3 minutes has elapsed since the start of the counting by the timer 176, the control unit 115 turns off the skin stimulus source 116 and also turns off the power supply to the light emitting element 138 and the head display unit 117, thereby stopping the cosmetic device (time t 9). That is, the power supply of the beauty appliance is cut off. When the user operates the power switch 103 before 3 minutes has elapsed from the start of the timer, the control unit 115 stops the cosmetic device at that time in the same manner as when 3 minutes has elapsed, and cuts off the power supply to the cosmetic device.

As shown in fig. 12, three determination regions having the minimum voltage Vm (0.8V) and the maximum voltage Vm (2.8V) as boundaries can be assumed for the output voltage V based on the light receiving amount of the light receiving element 139. When the output voltage V is within the "mole determination region" smaller than the minimum voltage Vm, the control unit 115 determines that the skin stimulator 3 is aligned with the mole. When the output voltage V is within the "sheet determination region" exceeding the maximum voltage VM, the control unit 115 determines that the cotton pad M is attached to the outer surface of the skin stimulating body 3. When 100% of the inspection light emitted from the light emitting element 138 is reflected, the upper limit of the "sheet determination region" of 3.0V is substantially equal to the voltage value output from the operational amplifier 179. When the output voltage V is within the "skin state determination region" in which the minimum voltage Vm is equal to or higher than the maximum voltage Vm and the maximum voltage Vm is equal to or lower than the maximum voltage Vm, the control unit 115 determines whether the skin state is normal or abnormal by comparing the output voltage V with the reference voltage V0. The initial value of the reference voltage V0 is set to a low value, preferably close to the minimum voltage Vm, within the range of the "skin state determination region", and varies (rises) in accordance with the skin color of the user within the range of the region. There is no case where the reference voltage V0 is lower than the minimum voltage Vm or higher than the maximum voltage Vm.

On the other hand, the timing chart of fig. 13 shows a case where the "skin abnormality detection mode" is selected in a state where the white cotton pad M is attached to the outer surface of the skin irritant 3. Immediately before time t0 to time t1, the output voltage V on the light receiving side shows 3.0V higher than the maximum voltage VM because the cotton pad M is attached at time t1 when irradiation of the inspection light is started, similarly to the above-described fig. 11. At the next time t10, control unit 115 that has received a high output voltage V determines that cotton pad M is in the mounted state, stops the irradiation of the inspection light, ends the "skin abnormality detection mode", and shifts to the normal "iontophoresis mode". During this movement, the head display unit 117 switches to red blinking display. Based on this, the user can recognize that the skin abnormality detection section 88 does not function due to the cotton pad M being mounted. After time t10, the output of each skin stimulus source 116 (current source 175, heater 164, vibrator 118) maintains a constant value corresponding to care level "1" in "skin abnormality detection mode". Since times t11 to t13 in fig. 13 are the same as times t7 to t9 in fig. 11, the description thereof is omitted. The time interval between time t1 and time t10 is extremely short, but for convenience of illustration in fig. 13, this interval is made longer than the actual interval.

In the present embodiment, at time t10, head display unit 117 is switched to red blinking display in order to notify the user of the stop of the function of skin abnormality detection unit 88, but instead, head display unit 117 may be lit or blinked in a color different from that at the time of driving skin abnormality detection unit 88, for example, and may be displayed as color change with a constant time interval. In addition, control may be performed to change the operation state of the sound mechanism such as a buzzer, instead of changing the display mode of the head display unit 117, or in combination with the change of the display mode. The sound control may switch the sound mechanism from a stopped state to an activated state, or may change the volume and tone of the sound mechanism. A synthesized voice notifying the user of the stop of the function of the skin abnormality detecting unit 88 in a language may be used.

(embodiment 2) fig. 14 shows an embodiment 2 of the beauty appliance of the present invention, and is different from the above-described embodiment 1 in that it includes a pair of upper and lower optical path forming members 140 and 141. Both the light path forming members 140 and 141 are fastened and fixed by a plurality of screws 181, and the lower surface of the second light path forming member 141 and the upper surface of the first light path forming member 140 which are in close contact with each other constitute joint surfaces 149 and 158, respectively. A pair of right and left light path grooves 150 and an engaging recess 151 between the pair of light path grooves 150 are formed in a recess in the joint surface 149 of the second light path forming body 141. A pair of right and left optical path grooves 159 facing the optical path groove 150 of the second optical path formation body 141 are formed concavely on the joint surface 158 of the first optical path formation body 140, and an engagement convex portion 160 engaging with the engagement concave portion 151 of the second optical path formation body 141 is provided protrudingly. The engagement concave portion 151 and the engagement convex portion 160 are engaged with each other to restrict the displacement of the two light path forming members 140 and 141 from each other along the joint surfaces 149 and 158, thereby facilitating fastening and fixing of the two light path forming members 140 and 141 by the screw 181. Except for this point, the same components as in embodiment 1 are denoted by the same reference numerals and their description is omitted.

(embodiment 3) fig. 15 and 16 show a beauty treatment instrument of embodiment 3 of the present invention, and the structure of the main lens 142 is different from that of embodiment 1. In the present embodiment, a concave portion 184 including a light incident surface 185 is formed on the inner surface (rear surface) of the lens 142 instead of the guide surface 171 of embodiment 1. The light incident surface 185 faces the light emitting element 138, and the angle θ formed by the light incident surface 185 and the inspection light emitted from the light emitting element 138 toward the center of the measurement section 143 is set to 98.5 ° which is nearly a right angle. In this way, when the light incident surface 185 at the angle θ perpendicular or close to the angle θ to the inspection light is formed in the lens 142, the amount of reflection of the inspection light at the light incident surface 185 can be minimized, and the light transmittance of the lens 142 can be improved.

In the present embodiment, the first light path forming body 140 and the second light path forming body 141 are joined to each other, so that the light path grooves 159 and 150 provided respectively face each other, thereby forming the hollow light guide path 187 through which the inspection light passes. The light guide 187 is formed in a V shape by a first light guide 188 from the light emitting element 138 to the lens 142 and a second light guide 189 from the lens 142 to the light receiving element 139. One end of each of the light guide paths 188, 189 is open to the light emitting element 138 or the light receiving element 139, and the other end of each of the light guide paths 188, 189 is open to the concave portion 184 of the lens 142.

In the present embodiment, the peripheral edge of the recess 184 is circumscribed with the opening edges of the first light guide 188 and the second light guide 189 on the contact surface where the lens 142 contacts the first light path forming body 140. Accordingly, there is no obstacle to the inspection light, so that the utilization efficiency of the inspection light can be improved, and the strength of the lens 142 can be improved. In contrast to the present embodiment, when the periphery of the concave portion 184 of the lens 142 extends toward the light guide paths 188 and 189, part of the inspection light may be blocked by the extending portion. Further, when the peripheral edge of the concave portion 184 is made larger as it is farther from the opening edge of each of the light guide paths 188 and 189, the strength of the lens 142 may be insufficient.

An O-ring 191 is fitted between the front surface of the peripheral portion of the lens 142 and the inner surface of the skin stimulating body 3 in place of the double-sided tape 173 of embodiment 1. The O-ring 191 is elastically deformed by being sandwiched between the skin irritant 3 and the lens 142, and seals the gap between the skin irritant 3 and the lens 142 in a watertight manner. Otherwise, the same components as those in embodiment 1 are denoted by the same reference numerals and their description is omitted. In this embodiment, the tip of the lens 142 is slightly projected from the window opening 35 of the skin stimulator 3, so that the peripheral edge of the window opening 35 of the skin stimulator 3 is less likely to contact the skin surface, and the skin surface is inhibited from being irritated by the metallic peripheral edge, which is similar to embodiment 1.

As described above, the beauty appliance of each of the above embodiments includes the skin irritant 3 that comes into contact with the skin surface and applies current stimulation or the like, and the skin abnormality detecting unit 88 that optically detects an abnormality of the skin surface, and the measuring unit 143 configured by the front surface of the lens 142 of the skin abnormality detecting unit 88 is disposed in the irritation surface 3a of the skin irritant 3. According to this beauty appliance, the skin surface can be cared by the skin stimulator 3 while the skin abnormality detector 88 checks the state of the skin surface by bringing the stimulation surface 3a into contact with the skin surface and then bringing the measurement portion 143 into direct contact with the skin surface. Therefore, compared to a conventional cosmetic method in which a skin health sensor and a cosmetic device are used independently of each other, the time required for detection of skin abnormality and care can be significantly shortened. Furthermore, the position of the abnormal portion on the skin surface can be precisely specified in real time, and the specified abnormal portion can be accurately and intensively treated. When the skin abnormality detecting unit 88 detects an abnormality in the skin surface, automatically increasing the output of the skin stimulus source 116 and operating the reporter 89 including the head display unit 117, the detection result of the skin abnormality detecting unit 88 is immediately reflected on the output of the skin stimulus source 116, and the user can be treated intensively and intensively without taking time and effort for switching the output, and it is possible to report to the user that there is a skin abnormality in the portion facing the skin stimulus body 3, and to prompt intensive care in the portion.

In the above-described embodiment, the amount of light received by the light receiving unit 139 is converted into a voltage value and output to the control unit 115, but the electrical output value may be a current value or a power value. The inspection light irradiated from the light emitting unit 138 may be ultraviolet light in the UVA region (315 to 380nm) or the UVB region (280 to 315nm), for example, in addition to the purple visible light. When ultraviolet light is used as the inspection light, skin abnormalities such as color spots can be detected with a high accuracy equal to or higher than that in the case of using violet visible light. Since the output of the inspection light is extremely weak, the skin surface is not damaged even if the inspection light composed of ultraviolet rays is used, but it is effective to intermittently irradiate the inspection light when the output of the inspection light needs to be enhanced due to a structural factor.

When the lens 142 is disposed in the window opening 35 of the skin stimulator 3, it is possible to prevent liquid, dust, and the like from entering the skin head 2 through the window opening 35, and to prevent the light emitting element 138, the light receiving element 139, and the like from being damaged by foreign matter entering through the window opening 35. The amount of transmitted inspection light can also be adjusted by the lens 142. However, even without the lens 142, the inspection light of the light emitting element 138 can be irradiated and the reflected light can be received by the light receiving element 139, and the lens 142 may be omitted if necessary. When the lens 142 is omitted, the space inside the window opening 35 constitutes the measurement section 143. The light emitting element 138 and the light receiving element 139 need not be disposed on the skin head 2, and may be disposed inside the main body casing 1. At this time, the optical path between the two elements 138, 139 and the lens 142 may be formed by an optical fiber or the like. Instead of the light emitting unit 138 and the light receiving unit 139, the skin abnormality detecting unit 88 may be configured to include a camera, for example. In this case, since the image of the skin surface captured by the camera is transmitted to the determination unit provided on the control board 7, the presence or absence of skin abnormality such as color spots is determined in real time.

The light emitting member 117 as the indicator 89 may be formed in an endless ring shape as in the above-described embodiment, an intermittent ring shape, a U shape, a semicircular shape, or the like. The ring shape of the present invention is a concept including a U shape, a semicircular shape, and the like. The light emitter 117 may be provided in the main body case 1 in addition to the skin head 2. The light emitting body 117 in this case is preferably provided on the head support part 100 not covered by the hand, rather than on the handle part 101 covered by the hand of the user when the cosmetic device is used. The head support portion 100 and the grip portion 101 may be both spanned. The notifying body 89 may be constituted by a buzzer for generating sound, for example, in addition to the light emitting body 117, the vibrator 118, and the heater 164. The reporter 89 may be formed of a display panel such as a liquid crystal panel or an organic EL panel, and in this case, the display panel may display characters such as "during mottling detection", "during blackout detection", and "during sheet attachment". The skin stimulating member 3 may be formed of a conductive resin or a conductive rubber, in addition to a metal. In the case of a cosmetic device that does not supply a pulse current to the skin stimulator 3, the skin stimulator 3 may be formed of an insulating resin or an insulating rubber.

The beauty treatment instrument according to each of the above embodiments can be implemented as follows.

A beauty treatment appliance is characterized by comprising: a skin stimulator 3 including a stimulation surface 3a which is brought into contact with the skin surface and gives stimulation; a skin stimulus source 116 for giving a physical cosmetic stimulus to the skin stimulus body 3; a control unit 115 for controlling the skin stimulus source 116; and a skin abnormality detecting section 88 for optically detecting abnormality on the skin surface,

the skin abnormality detection unit 88 includes a measurement unit 143 opposed to the measurement target portion on the skin surface,

the measurement unit 143 is disposed inside the outer contour line of the stimulation surface 3a when viewed from the front facing the stimulation surface 3 a.

The beauty appliance of the present invention described above includes the skin stimulator 3 including the stimulation surface 3a which is brought into contact with the skin surface and applies stimulation, and the skin abnormality detection unit 88 which optically detects abnormality of the skin surface, and the measurement unit 143 of the skin abnormality detection unit 88 is disposed inside the outer contour line of the stimulation surface 3 a. According to this cosmetic device, when the stimulation surface 3a is brought into contact with the skin surface, the skin surface can be cared by the skin stimulator 3 while the skin abnormality detection section 88 checks the state of the skin surface by aligning the measurement section 143 with the skin surface. Therefore, compared to a conventional cosmetic method in which a skin health sensor and a cosmetic device are used independently of each other, the time required for detection and care of skin abnormality can be significantly shortened. Moreover, the position of the abnormal portion on the skin surface can be precisely specified in real time, and the specified abnormal portion can be accurately and intensively treated. Further, by disposing the measurement section 143 in the outer contour line of the stimulation surface 3a, it is possible to detect and care for skin abnormality in the same posture, and it is possible to save labor and time for changing the posture of the beauty appliance and changing hands. In contrast to the present invention, when a skin irritant and a skin abnormality detection unit are disposed at different positions of a cosmetic device, the posture of the cosmetic device is changed and the hands are changed, which takes time and effort when the skin abnormality is detected and the care is changed.

In the cosmetic device, when the skin abnormality detection unit 88 detects an abnormality on the skin surface, the control unit 115 increases the output of the skin stimulus source 116.

According to the cosmetic device in which the control unit 115 boosts the output of the skin stimulus source 116 when the skin abnormality detection unit 88 detects an abnormality on the skin surface, the detection result of the skin abnormality detection unit 88 can be reflected at once on the intensity of the skin stimulus, and the detected abnormal portion can be cared for strongly and intensively. Further, since the skin irritation is automatically enhanced at the time of detection of the skin abnormality, it is possible to save labor and time for the user to switch the output of the skin irritation source 116.

The beauty appliance comprises a report body 89 for generating at least one of sound, light and vibration,

when the skin abnormality detection unit 88 detects an abnormality on the skin surface, the control unit 115 operates the reporter 89.

According to the beauty appliance in which the control unit 115 operates the notifying body 89 when the skin abnormality detecting unit 88 detects an abnormality on the skin surface, it is possible to immediately notify the user of an abnormal portion on the skin surface by sound or the like, and thus it is possible to promote intensive care of the portion.

In the cosmetic device, a measurement portion 143 is disposed at a central portion of the stimulation surface 3a of the skin stimulator 3.

When the measuring portion 143 is disposed at the center portion of the stimulation surface 3a of the skin stimulator 3, the user can accurately identify the abnormal portion on the skin surface, as compared with the case where the measuring portion 143 is provided at the peripheral portion of the stimulation surface 3 a. When the user who has determined that there is a skin abnormality in the portion in contact with the center portion of the stimulation surface 3a leaves the beauty appliance at that position, care can be given to the abnormal portion and its surroundings without omission.

In the cosmetic device, the skin stimulator 3 is formed of an electric conductor, and constitutes a skin detection sensor for detecting the contact of the stimulation surface 3a with the skin surface,

the control unit 115 controls the driving state of the skin abnormality detection unit 88 based on the detection signal of the skin detection sensor.

If the skin irritant 3 is formed of an electric conductor and constitutes a skin detection sensor for detecting that the irritant surface 3a is in contact with the skin surface, the contact of the irritant surface 3a with the skin surface can be detected easily and accurately, as compared with the case where the skin detection sensor is formed independently of the skin irritant 3. If the control unit 115 controls the driving state of the skin abnormality detection unit 88 based on the detection signal of the skin detection sensor, the skin abnormality detection unit 88 is not driven uselessly in a state where the stimulation surface 3a is away from the skin surface, and the power consumption of the cosmetic device can be suppressed.

A cosmetic device comprises a skin head 2 having a skin stimulating body 3, and a main body case 1,

the main body case 1 includes a head support 100 for supporting the skin head 2 and a grip 101 usable as a grip,

at least a part of the light emitting body 117 constituting the report body 89 is provided to the head support 100 or the skin head 2.

In a state where the user holds the grip portion 101 of the main body casing 1, the head support portion 100 is more likely to enter the field of view of the user than the skin head 2, and is not blocked by the hand of the user as in the grip portion 101. Therefore, if at least a part of the light emitter 117 constituting the notification body 89 is provided on the head support part 100 or the skin head 2, the user can easily visually confirm the light emitter 117, and the user can be reliably notified that the skin abnormality detection part 88 has detected an abnormality on the skin surface.

In the cosmetic device, the light emitting body 117 is formed in an intermittent or continuous ring shape.

When the light emitting body 117 is formed in an intermittent or continuous ring shape, the appearance and contour of the beauty appliance can be made more conspicuous in a state where a larger area is illuminated than in a case where a dot-shaped light emitting body 117 is locally arranged. Therefore, the appearance design of the beauty appliance can be improved, and the commercial value thereof can be improved.

In the beauty appliance, a light-releasing body 117 is arranged on the outer peripheral surface of a skin head 2 between a skin stimulator 3 and a head support 100,

a light shielding wall 128 is formed between the stimulation surface 3a of the skin stimulator 3 and the light emitter 117,

when viewed from the front facing the stimulating surface 3a, the light emitting surface of the light emitter 117 is positioned inside the outer contour line of the light blocking wall 128, and the light emitter 117 emits light to the outside of the outer contour line.

According to the beauty appliance in which the light emitting body 117 is positioned inside the outer contour line of the light blocking wall 128 and emits light to the outside of the outer contour line, when the user looks at the stimulation surface 3a of the skin stimulator 3 in front, the light emitting surface of the light emitting body 117 is blocked by the light blocking wall 128 and is not seen by the eyes of the user, and thus only the light emitted by the light emitting body 117 can be reflected to the eyes of the user. Therefore, it is possible to eliminate the glare light from being applied to the eyes of the user, and to form a fantastic atmosphere in which the skin irritant 3 is surrounded by the blurred and soft light, thereby further improving the design of the cosmetic device.

In the cosmetic device, the report body 89 includes a vibrator 118.

If the report body 89 includes the vibrator 118, it can be reported to the user via the tactile sense that the skin abnormality detection unit 88 has detected an abnormality on the skin surface by the vibration of the vibrator 118. Therefore, even for a user with blindness or a user in a state of eye closure, the presence of skin abnormality can be reliably reported.

In the cosmetic device, the skin abnormality detection unit 88 includes: a light emitting unit 138 that emits inspection light toward a measurement target portion on the skin surface facing the measurement unit 143; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion,

the control unit 115 determines that the measurement target unit is in a normal state when the amount of light received by the light receiving unit 139 is equal to or greater than a predetermined reference light amount, and determines that the measurement target unit is in an abnormal state when the amount of light received is less than the reference light amount, and performs at least one of control for enhancing the output of the skin stimulus source 116 and control for operating the reporter 89.

The measurement portion on the skin surface is irradiated with the inspection light from the light emitting unit 138, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount, it is determined that the measurement portion is in a normal state, and conversely, if the light receiving amount is less than the reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

In the cosmetic device, the skin abnormality detection unit 88 includes: a light emitting unit 138 that emits inspection light toward a measurement target portion on the skin surface facing the measurement unit 143; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion and outputting an electrical output value corresponding to the amount of light received,

the control unit 115 determines the state of the measurement target unit by comparing the electrical output value of the light receiving unit 139 with a predetermined electrical reference value, and performs at least one of control for increasing the output of the skin stimulus source 116 and control for operating the reporter 89 when it is determined that the measurement target unit is in an abnormal state.

The light emitting unit 138 emits the inspection light to the skin surface, and the light receiving unit 139 that receives the reflected light outputs an electric output value such as a current or a voltage corresponding to the amount of light received. Then, the state of the skin surface is determined by comparing the electrical output value of the light receiving section 139 with a predetermined electrical reference value. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

In the beauty appliance, the control part 115 comprises a storage part 177 for storing the electric reference value,

when the amount of light received corresponding to the electrical output value of the light receiving part 139 is larger than the reference light amount indicated by the electrical reference value stored in the storage part 177, the electrical output value is stored in the storage part 177 as a new electrical reference value.

As for the light amount of the inspection light reflected by the skin surface of the user, the whiter the skin is, the more the skin is, and the darker the skin is, the less the skin is. Therefore, if the average skin color reflected light amount is set as the reference light amount, when a user who is whiter than the average skin color uses the beauty appliance, the reflected light amount is higher than the reference light amount even in an abnormal portion such as a color patch, and the abnormal portion may be erroneously determined as normal. On the other hand, when the user who is darker than the average skin color uses the beauty appliance, the reflected light amount is also lower than the reference light amount at the normal portion, and the normal portion may be erroneously determined as abnormal. Therefore, in the present invention, when the light receiving amount corresponding to the electrical output value of the light receiving part 139 is larger than the reference light amount indicated by the electrical reference value stored in the storage part 177, the output value is stored in the storage part 177 as a new electrical reference value. Accordingly, the user moves the beauty appliance along the skin surface, and updates the electrical reference value every time the measurement unit 143 is aligned with a whiter portion of the skin color, thereby setting the electrical reference value based on the whitest portion of the skin color of the user. As described above, according to the present invention, it is possible to set an appropriate electrical reference value that matches the skin color of the user, and it is possible to accurately detect skin abnormalities such as color spots regardless of the skin color.

A beauty treatment appliance is characterized by comprising: a skin stimulator 3 including a stimulation surface 3a which is brought into contact with the skin surface and gives stimulation; a skin stimulus source 116 for giving a physical cosmetic stimulus to the skin stimulator 3; and a skin abnormality detecting section 88 for optically detecting abnormality on the skin surface,

the skin abnormality detection unit 88 includes: a measurement unit 143 facing the measurement unit on the skin surface; a light emitting unit 138 for emitting the inspection light toward the measurement target portion; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion,

the light receiving amount of the light receiving unit 139 is set to a predetermined reference light amount and a predetermined upper limit reference light amount larger than the reference light amount,

when the amount of light received by the light receiving unit 139 is equal to or greater than the reference light amount and equal to or less than the upper limit reference light amount, it is determined that the measurement target unit is in the normal state, when the amount of light received is less than the reference light amount, it is determined that the measurement target unit is in the abnormal state, and when the amount of light received is greater than the upper limit reference light amount, it is determined that an obstacle (for example, covered with a white sheet-like body M) that is an obstacle to skin detection is present in the measurement unit 143.

The inspection light is irradiated from the light emitting unit 138 to the measurement portion on the skin surface, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount and equal to or less than an upper limit reference light amount, it is determined that the measurement portion is in a normal state, and conversely, if the light receiving amount is less than the reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. When the light receiving amount of the light receiving unit 139 is higher than the upper limit reference light amount, if it is determined that an obstacle (for example, covered with a white sheet M) which is an obstacle to the detection of the skin is present in the measuring unit 143, the following problems can be avoided: an obstacle such as the sheet-like body M is mistaken for a white skin surface, and the output of the skin stimulus source 116 is controlled based on the mistaken recognition, so that the skin surface cannot be appropriately treated.

A beauty treatment appliance is characterized by comprising: a skin stimulator 3 including a stimulation surface 3a which is brought into contact with the skin surface and gives stimulation; a skin stimulus source 116 for giving a physical cosmetic stimulus to the skin stimulator 3; and a skin abnormality detecting section 88 for optically detecting abnormality of the skin surface,

the skin abnormality detection unit 88 includes: a measurement unit 143 facing the measurement target portion on the skin surface; a light emitting unit 138 for emitting the inspection light toward the measurement target portion; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion and outputting an electrical output value corresponding to the amount of light received,

the electrical output value of the light receiving unit 139 is set to a predetermined electrical reference value and a predetermined upper limit electrical reference value larger than the electrical reference value,

when the electrical output value of the light receiving unit 139 is equal to or greater than the electrical reference value and equal to or less than the upper limit electrical reference value, it is determined that the measured portion is in a normal state, when the electrical output value is lower than the electrical reference value, it is determined that the measured portion is in an abnormal state, and when the electrical output value is higher than the upper limit electrical reference value, it is determined that an obstacle (for example, covered with a white sheet body M) which is an obstacle in detecting the skin is present in the measuring portion 143.

The light emitting unit 138 emits the inspection light to the measurement portion on the skin surface, and the light receiving unit 139 that receives the reflected light outputs electrical output values such as current and voltage corresponding to the amount of received light. Then, when the electrical output value of the light receiving unit 139 is equal to or greater than the predetermined electrical reference value and equal to or less than the upper limit electrical reference value, it is determined that the measurement target portion is in the normal state, and when the electrical output value is lower than the electrical reference value, it is determined that the measurement target portion is in the abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, which is an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. When the electrical output value of the light receiving unit 139 is higher than the upper limit electrical reference value, if it is determined that an obstacle (for example, covered with a white sheet M) that is an obstacle to detecting the skin is present in the measuring unit 143, the following disadvantages can be avoided: an obstacle such as the sheet M is mistaken for a skin surface with white skin, and the output of the skin stimulus source 116 is controlled based on the mistaken recognition, which may result in a problem that the skin surface cannot be appropriately treated.

In the cosmetic device, when it is determined that the portion to be measured on the skin surface is in an abnormal state, at least one of the control of increasing the output of the skin stimulus source 116 and the control of operating the reporter 89 that reports the abnormal state on the skin surface is performed.

If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

In the cosmetic device, when it is determined that an obstacle (for example, covered with a white sheet-like body M) which obstructs the detection of the skin is present in the measurement section 143, at least one of the control of stopping the driving of the skin abnormality detection section 88 and the control of operating the reporter 89 is performed.

Since the skin abnormality detection unit 88 cannot measure the skin state in a state where the measurement unit 143 is covered with an obstacle such as the sheet-like body M, stopping the driving of the skin abnormality detection unit 88 in this case can reliably prevent the increase in power consumption caused by the unnecessary continuous driving of the skin abnormality detection unit 88. In this case, when the reporter 89 is activated, it is reported to the user that the measurement section 143 is covered with an obstacle such as the sheet body M and the skin abnormality detection section 88 is not functioning, and the user can be prompted to take appropriate measures such as removing the obstacle such as the sheet body M.

A beauty appliance is characterized by comprising: a skin stimulator 3 including a stimulation surface 3a which is brought into contact with the skin surface and gives stimulation; a skin stimulus source 116 for giving a physical cosmetic stimulus to the skin stimulator 3; and a skin abnormality detecting section 88 for optically detecting abnormality on the skin surface,

the skin abnormality detection unit 88 includes: a light emitting unit 138 that emits examination light toward a measurement area on the skin surface; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion,

the light receiving amount of the light receiving unit 139 is set to a predetermined reference light amount and a predetermined lower limit reference light amount smaller than the reference light amount,

when the amount of light received by the light receiving unit 139 is equal to or greater than the reference light amount, it is determined that the measurement target unit is in a normal state, when the amount of light received is less than the reference light amount and equal to or greater than the lower limit reference light amount, it is determined that the measurement target unit is in an abnormal state, and when the amount of light received is less than the lower limit reference light amount, it is determined that the measurement target unit is not in an abnormal state but is a nevus.

The measurement portion on the skin surface is irradiated with the inspection light from the light emitting unit 138, and if the reflected light amount at this time, that is, the light receiving amount of the light receiving unit 139 is equal to or more than a predetermined reference light amount, it is determined that the measurement portion is in a normal state, and conversely, if the light receiving amount is lower than the reference light amount and equal to or more than a lower limit reference light amount, it is determined that the measurement portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., the light amount, and the configuration of the skin abnormality detection unit 88 can be simplified, and the skin condition can always be accurately determined. When the amount of light received by the light receiving unit 139 is less than the lower limit reference light amount, if it is determined that the unit to be measured is not in an abnormal state but rather is a moles, moles that do not require care can be accurately detected, and thus useless care can be prevented.

A beauty treatment appliance is characterized by comprising: a skin stimulator 3 including a stimulation surface 3a which is in contact with the skin surface and gives stimulation; a skin stimulus source 116 for giving a physical cosmetic stimulus to the skin stimulus body 3; and a skin abnormality detecting section 88 for optically detecting abnormality of the skin surface,

the skin abnormality detection unit 88 includes: a light emitting unit 138 that emits examination light toward a measurement area on the skin surface; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion and outputting an electrical output value corresponding to the amount of light received,

the electrical output value of the light receiving unit 139 is set to a predetermined electrical reference value and a predetermined lower limit electrical reference value smaller than the electrical reference value,

when the electrical output value of the light receiving unit 139 is equal to or greater than the electrical reference value, it is determined that the measurement target unit is in a normal state, when the electrical output value is lower than the electrical reference value and equal to or greater than the lower limit electrical reference value, it is determined that the measurement target unit is in an abnormal state, and when the electrical output value is lower than the lower limit electrical reference value, it is determined that the measurement target unit is not in an abnormal state but a mole.

The light emitting unit 138 emits the inspection light to the measurement target portion on the skin surface, and the light receiving unit 139 that receives the reflected light outputs electrical output values such as current and voltage corresponding to the amount of light received. Then, when the electrical output value of the light receiving unit 139 is equal to or greater than a predetermined electrical reference value, it is determined that the measured portion is in a normal state, and conversely, when the electrical output value is lower than the electrical reference value and equal to or greater than a lower limit electrical reference value, it is determined that the measured portion is in an abnormal state. According to this determination method, the skin condition can be determined on a simple and quantitative basis, i.e., an electrical output value, and the skin condition can always be accurately determined while simplifying the configuration of the skin abnormality detection unit 88. When the electrical output value of the light receiving unit 139 is lower than the lower limit electrical reference value, if it is determined that the measured portion is not in an abnormal state but rather a mole, a mole that does not require care can be accurately detected, and thus useless care for a mole can be prevented.

In the cosmetic device, when it is determined that the portion to be measured on the skin surface is in an abnormal state, at least one of the control of increasing the output of the skin stimulus source 116 and the control of operating the reporter 89 that reports the abnormal state on the skin surface is performed.

If the output of the skin stimulus sources 116 is increased at an abnormal portion of the skin surface, the portion can be treated intensively and intensively, and the labor and time for the user to switch the output of the skin stimulus sources 116 can be saved. Further, when the reporter 89 is operated at an abnormal portion of the skin surface, the portion can be immediately reported to the user, and the intensive care of the portion can be promoted.

In the beauty appliance, when the light receiving amount of the light receiving unit 139 is lower than the lower limit reference light amount, or the electrical output value of the light receiving unit 139 is lower than the lower limit electrical reference value, and it is determined that the measured portion of the skin surface is not in an abnormal state but is a moles, at least one of the control of attenuating or stopping the output of the skin stimulus source 116 and the control of operating the reporter 89 is performed.

When it is determined that the part to be measured on the skin surface is not in an abnormal state but rather a moles, if the output of the skin stimulus source 116 is attenuated or stopped, it is possible to more reliably prevent the unwanted treatment of moles. In this case, when the reporter 89 is activated, it is possible to immediately report to the user that the measured part is a black mole, and thus it is possible to prompt attention so as not to apply useless stimulation to the black mole.

In the cosmetic device, the light emitting body 117 and/or the vibrator 118 are operated in a state where the skin stimulating body 3 gives the cosmetic stimulation to the skin surface,

when the skin abnormality detection unit 88 detects a skin abnormality, the control unit 115 changes the operation state of the light emitter 117 and/or the vibrator 118.

When the light emitting unit 117 and/or the vibrator 118 is operated in a state where the skin irritant 3 applies cosmetic irritation to the skin surface, the user can more reliably recognize that skin irritation is output from the skin irritant 3. Further, according to the configuration in which the operation state of the light emitter 117 and/or the vibrator 118 is changed at the time of detecting the skin abnormality, the light emitter 117 and/or the vibrator 118 can be used not only as the display body showing the output of the skin irritation from the skin irritant 3 but also as the notification body 89 notifying the detection of the skin abnormality, so that the number of components constituting the beauty appliance can be reduced and the cost can be reduced accordingly, as compared with the case where the display body and the notification body 89 are separately provided.

In the cosmetic device, when detecting a skin abnormality, control is performed to increase the illuminance of the light emitter 117 and/or control is performed to increase the vibration level of the vibrator 118.

When the illuminance of the light emitter 117 is controlled to be increased and/or the vibration level of the vibrator 118 is controlled to be increased at the time of detecting the skin abnormality, the user can recognize that the skin abnormality is detected with a direct sense of feeling.

In the cosmetic device, the inspection light emitted from the light emitting unit 138 is visible light having a peak in a violet wavelength region.

The inspection light emitted from the light emitting unit 138 is preferably an electromagnetic wave having a large difference in reflectance between a normal portion and an abnormal portion of the skin surface, that is, an electromagnetic wave that is easily absorbed by melanin pigment causing color spots or the like. Examples of such electromagnetic waves include violet visible light. When visible light having a peak in the violet wavelength region is used as the inspection light, skin abnormality such as color spots can be detected with higher accuracy than when visible light having a longer wavelength is used. Further, if the inspection light is visible light, the user can clearly recognize that the inspection light is emitted from the light emitting unit 138 without damaging the skin surface.

In the cosmetic device, the inspection light irradiated from the light emitting unit 138 is ultraviolet light in the UVA region or the UVB region.

When ultraviolet light in the UVA region or UVB region is used as the inspection light, skin abnormality such as color spots can be detected with high accuracy equal to or higher than that in the case of using visible light having a peak in the violet wavelength region.

In the beauty appliance, the light emitting unit 138 intermittently emits inspection light.

When the inspection light composed of ultraviolet rays is intermittently irradiated, damage to the skin surface can be reduced as compared with the case where the inspection light is continuously irradiated. In general, since the output of the inspection light is extremely weak, the skin surface is not damaged even when the inspection light composed of ultraviolet rays is used, but it is effective to intermittently irradiate the inspection light when the output of the inspection light needs to be enhanced due to structural factors.

In the cosmetic device, the skin stimulus source 116 is constituted to include a current source 175,

a current for skin stimulation is supplied from the current source 175 to the skin stimulator 3 formed of a conductive body.

When a current for skin stimulation is supplied from the current source 175 to the skin stimulator 3, it is possible to perform a cosmetic treatment that has an effect such as iontophoresis for immersing the cosmetic liquid into the skin surface, including the abnormal portion detected by the skin abnormality detecting unit 88.

In a beauty appliance, a handle electrode 10 is provided on a handle part 101 of a main body case 1,

the handle electrode 10 is brought into contact with the surface of the hand, and the stimulation surface 3a of the skin stimulator 3 is brought into contact with the skin surface, whereby a closed loop capable of being detected by the control unit 115 is formed across the beauty appliance and the human body,

In a state where the control unit 115 detects the closed loop, the current source 175 is controlled so as to supply a current for skin stimulation to the skin stimulator 3.

When the handle electrode 10 is in contact with the surface of the hand and the stimulation surface 3a of the skin irritant 3 is in contact with the skin surface, thereby forming a closed loop across the beauty appliance and the human body that can be detected by the control unit 115, the skin irritant 3 can be made to function as a skin detection sensor that detects the contact of the stimulation surface 3a with the skin surface. Accordingly, as compared with the case where the skin detection sensor is provided at a different site from the skin irritant 3, it is possible to easily and accurately detect that the irritant surface 3a is in contact with the skin surface. When the control unit 115 detects the closed loop, it supplies the skin stimulating current to the skin stimulating body 3, and stops the supply of the skin stimulating current when the closed loop is not formed, that is, when the stimulation surface 3a is away from the skin surface, thereby suppressing the power consumption of the beauty appliance.

In the cosmetic device, the skin abnormality detection unit 88 includes: a light emitting unit 138 that irradiates the measurement target portion on the skin surface facing the measurement unit 143 with the inspection light; a light receiving unit 139 that receives the inspection light reflected by the measurement portion; and first and second light path forming bodies 140, 141,

The first light path forming body 140 and the second light path forming body 141 are joined via the joining surfaces 149 and 158,

light path grooves 150 and 159 for dividing the light path of the inspection light are formed along the joint surfaces 149 and 158 of the pair of light path forming members 140 and 141.

When the optical path grooves 150 and 159 for dividing the optical path of the inspection light are formed along the joining surfaces 149 and 158 of the pair of optical path forming members 140 and 141 in a recessed manner, the optical path of the inspection light can be easily and accurately formed only by joining the optical path forming members 140 and 141 to each other at the time of assembling the cosmetic device.

In the cosmetic device, the first light path forming body 140 is opposed to the inner surface of the stimulation surface 3a of the skin stimulator 3,

the second light path forming body 141 includes the light emitting portion 138 and the receiving portions 147 and 148 of the light receiving portion 139.

If the second light path formation member 141 includes the housing portions 147 and 148 of the light emitting portion 138 and the light receiving portion 139, the number of components constituting the skin abnormality detection portion 88 can be reduced, and accordingly, the cost can be reduced, compared to a case where a holder for the light emitting portion 138 and the like is prepared independently.

In the cosmetic device, the skin stimulation source 116 includes a heater 164 for heating the skin stimulator 3,

a heater support portion 165 that supports the heater 164 is formed on the surface of the first light path formation member 140 that faces the skin stimulator 3.

When the skin irritant 3 is heated by the heater 164, the skin surface including the abnormal portion detected by the skin abnormality detecting unit 88 can be subjected to the cosmetic treatment effective to apply the thermal stimulus. When the heater supporting portion 165 supporting the heater 164 is formed in the first light path forming body 140, the number of components constituting the skin abnormality detecting portion 88 can be reduced compared to a case where a holder for the heater 164 is prepared independently, and accordingly, the cost can be reduced.

In the cosmetic device, the skin stimulus source 116 includes a current source 175 and a heater 164 for heating the skin stimulator 3.

If the skin stimulus source 116 is configured to include the current source 175 and the heater 164, it is possible to apply current stimulus and thermal stimulus to the skin surface including the abnormal portion detected by the skin abnormality detection unit 88. Therefore, a plurality of stimuli can be given to the skin surface, and more effective cosmetic treatment can be performed.

In the cosmetic device, the skin stimulation source 116 includes a vibrator 118 for vibrating the skin stimulator 3,

the vibrator 118 is supported by a vibrator holder 120, and is accommodated inside the skin irritant 3,

The skin abnormality detector 88 is held and fixed between the skin stimulator 3 and the vibrator holder 120.

When the skin stimulator 3 is vibrated by the vibrator 118, cosmetic treatment effective to apply vibration stimulation to the skin surface including the abnormal portion detected by the skin abnormality detection unit 88 can be performed. When the skin abnormality detecting unit 88 is sandwiched and fixed by the skin irritant 3 and the vibrator holder 120, the posture of the skin abnormality detecting unit 88 can be stabilized, and the reliability of detection by the skin abnormality detecting unit 88 can be improved.

In the cosmetic device, the skin abnormality detection unit 88 includes: a light emitting unit 138 that emits inspection light toward a measurement target portion on the skin surface facing the measurement unit 143; and a light receiving unit 139 for receiving the inspection light reflected by the measurement portion,

the substrate 137 supporting the light emitting unit 138 and the light receiving unit 139 is sandwiched and fixed by the skin irritant 3 and the vibrator holder 120 together with the skin abnormality detecting unit 88.

When the substrate 137 supporting the light emitting unit 138 and the light receiving unit 139 is sandwiched and fixed by the skin irritant 3 and the vibrator holder 120 together with the skin abnormality detecting unit 88, the assembly procedure of the beauty appliance can be simplified and the cost can be reduced by comparison with a case where the substrate 137 is fixed by a mechanism different from the fixing mechanism of the skin abnormality detecting unit 88.

(embodiment 4) fig. 17 to 25 show a beauty appliance of embodiment 4 of the present invention. Note that, in the present embodiment, front-back, left-right, and up-down are based on the intersecting arrows shown in fig. 18 and 19, and the front-back, left-right, and up-down displays indicated in the vicinity of each arrow.

In fig. 18 and 19, the beauty appliance includes a vertically long main body case 1 also serving as a handle, and a skin head 2 provided to protrude from an upper portion of a front surface of the main body case 1, and includes a skin stimulator (skin electrode) 3 at a front end of the skin head 2. The main body case 1 is formed in a hollow case shape by a front case 1a and a rear case 1b formed by dividing front and rear. A switch panel 6 is provided on the upper portion of the rear surface of the rear case 1b, and the switch panel 6 includes a switch button 4 for power connection, a switch button 5 for switching the operation mode, and a switch button (not shown) for switching the current intensity. A control board 7 is provided inside the main body case 1 facing the switch panel 6, and a battery 8 is disposed below the control board. The control board is provided with switches 4a and 5a that are turned on and off by the switch buttons 4 and 5, an LED9 that displays the operating state of the beauty appliance, a control circuit that controls the operation of the heater 31 and the light source 26 described later, and adjusts the current supplied to the skin stimulating body 3, and the like. Handle electrodes 10 are fixed to both left and right sides of the main body case 1, and the handle electrodes 10 are connected to the control board 7 via electrode leads 54 not shown in fig. 19. In fig. 19, reference numeral 11 denotes a battery cover which is opened and closed by sliding.

As shown in fig. 20 and 21, a circular mounting seat 14 for mounting the skin head 2 and a cylindrical head support 15 are integrally provided on the upper front surface of the front case 1a, and a head case 16 for supporting the skin stimulator 3 is mounted on the mounting seat 14. The head case 16 is made of a milky translucent plastic molding, and a cap fitting portion 17 is projected in a circumferential manner on the front end peripheral surface of the cylindrical tube portion. A coupling cylindrical wall 18 into which the mount 14 is fitted is formed at the rear end of the cylindrical portion. A front opening 19 for fitting the skin stimulator 3 is formed at the front end of the head housing 16, and a step 20 for receiving the skin stimulator 3 is continuously formed at the inner end of the front opening 19.

The middle portion in the front-rear direction of the cylindrical wall of the head case 16 serves as an irradiation light visual confirmation unit 21 for visually confirming a part of the light irradiated from the light source 26. The head case 16, the front case 1a, and a light guide 27 described later are integrated by four screws 22 screwed from the inner surface of the front case 1a to the coupling cylinder wall 18. In this assembled state, the gap between the outer peripheral wall continuous with the assembly seat 14 and the connecting cylinder wall 18 is sealed by the O-ring 23. In fig. 18 and 19, reference numeral 64 denotes an annular holding cap for holding the cotton pad M, and the holding cap 64 is press-fitted into the cap fitting portion 17 to fix and hold the cotton pad M fitted to the outer surface of the skin irritant 3.

As described above, if the head case 16 is formed of a translucent plastic molded product and the irradiation light visual confirmation portion 21 is provided at a part of the peripheral surface thereof, the appearance of the skin head 2 can be made neat as compared with the case where a window is opened in the head case 16 as the irradiation light visual confirmation portion 21, and the design of the beauty appliance can be improved. Further, by disposing the irradiation light visual confirmation unit 21 in a state of intersecting the optical path of the irradiation light irradiated from the light irradiation mechanism 58, the illuminance at the irradiation light visual confirmation unit 21 can be increased, and it is possible to clearly report to the user that the cosmetic device is in operation.

The head case 16 is provided therein with a heater holder 25, a light source 26, and a light guide 27 for guiding light emitted from the light source 26 to the outer surface of the skin stimulating body 3, and the skin stimulating body 3 is attached to the front opening 19 at the front end of the head case 16 in a state of protruding forward from the front opening 19. The heater holder 25 is formed in a disk shape, four bosses 28 are provided on the rear surface thereof, and the heater holder 25 and the head support 15 are integrated by screwing screws 29 inserted through the front end wall of the head support 15 into the bosses 28. An elastic ring 30 made of silicone rubber is provided on the front surface of the heater holder 25, and the ring-shaped heater 31 is pressed against the skin stimulating body 3 by the ring 30. A spring 32 for supplying a positive or negative current is disposed between the heater holder 25 and the skin stimulating body 3. The spring 32 is connected to the control board 7 through an electrode lead 53 not shown in fig. 19.

The light source 26 is constituted by a so-called three-primary-color white LED including three shell-shaped LEDs of a red LED26R, a green LED26G, and a blue LED26B, which are three primary colors that emit light independently. When the three LEDs are simultaneously emitted, visible light close to natural light can be emitted, and when the three LEDs are independently emitted, red light, green light, and blue light can be emitted. Further, when the red LED26R and the green LED26G are simultaneously emitted, yellow light can be emitted, and when the red LED26R and the blue LED are simultaneously emitted, violet light can be emitted. By adjusting the current value supplied to each of the LEDs 26R, 26G, 26B, the intensity (illuminance) of each light can be increased in proportion to the current value.

The skin stimulator 3 is formed of a press-formed product of a titanium plate material in a circular cap shape, and a flange-like mounting wall 34 is formed to extend around the inner opening edge. A circular window opening 35 for exposing the light guide 27 is formed in the center of the stimulation surface 3a on the front surface of the skin stimulation unit 3. As shown in fig. 20, in a state where the connecting cylindrical wall 18 of the head housing 16 is fastened to the mounting seat 14 by the screw 22, the O-ring (second sealing body) 36 fitted to the fitting wall 34 is sandwiched between the fitting wall 34 and the step portion 20 of the head housing 16 and elastically deformed, thereby sealing the gap between the front opening 19 and the peripheral wall of the skin irritant 3.

As shown in fig. 17, the light source 26 faces the window opening 35 of the skin stimulator 3 with the light adjustment space S therebetween, and the light guide 27 is disposed in the light adjustment space S. The light guide 27 is composed of a front stage light guide 38 serving also as a holder for the light source 26, and a rear stage light guide 39 disposed between the front stage light guide 38 and the skin stimulator 3. The front-stage light guide 38 is formed of a light-transmissive plastic material, and integrally includes a flange-shaped base portion 40, a light source holder portion 41 provided on the front surface of the base portion 40 and to which the LEDs 26R, 26G, and 26B are attached, and a support tube portion 42 provided on the front side of the holder portion 41 and supporting the rear-stage light guide 39. A mounting recess (mounting portion) 43 for receiving the light emitting portions of the LEDs 26R, 26G, 26B is formed in a recessed manner on the rear surface of the light source holder 41. The base portion 40 is fastened and fixed to the seat wall of the mount seat 14 by the screw 22 together with the connecting cylinder wall 18 of the head housing 16.

The rear stage light guide 39 is formed of a light-transmissive plastic material containing a filler 65 (see fig. 22) having a light diffusing effect, and integrally includes a disk-shaped light guide portion 45, an irradiation portion 46 provided so as to protrude from the front surface of the light guide portion 45, and a cylindrical coupling cylinder portion 47 provided so as to protrude from the rear surface of the light guide portion 45. The filler 65 may be a material having a refractive index different from that of the rear stage light guide 39, and particles of polycrystalline silicon, aluminum hydroxide, silica glass, metal particles, fine bubbles, and the like may be used. An irradiation surface 48 is formed on the front surface of the irradiation portion 46, and seven convex portions 49 are formed on the irradiation surface 48. As described above, when the rear-stage light guide 39 is formed of a plastic molded product containing the filler 65 having a light diffusion effect, the filler 65 promotes the scattering effect of light inside the rear-stage light guide 39, and the illuminance of light irradiated toward the skin surface can be made uniform without unevenness. Therefore, the light irradiated from the irradiation surface 48 can be made more uniform, and the discomfort caused by the light with high illuminance entering the eyes of the user can be eliminated.

As shown in fig. 22, the irradiation surface 48 is concavely curved toward the inner surface of the skin stimulator 3, and a flat surface 48a is formed at the tip of the peripheral edge thereof. The convex portions 49 are formed in a partially spherical shape, and concave portions 50 are formed between adjacent convex portions 49. In this way, by providing the convex portion 49, the cosmetic treatment is performed by gradually sliding the stimulation surface 3a of the skin stimulator 3 along the facial skin, and at this time, the convex portion 49 can contact the facial skin to apply the frictional stimulation, thereby improving the cosmetic effect. Further, since the cosmetic treatment can be performed in a state where the cosmetic liquid having a high viscosity such as a lotion is held on the irradiation surface 48 by the convex portion 49 and the concave portion 50, unnecessary application of the cosmetic liquid to the skin surface can be prevented.

A seal holder 51 slightly larger than the window opening 35 is formed in a stepped manner between the base end of the irradiation portion 46 and the peripheral tip end of the light guide portion 45, and an O-ring (first seal body) 52 fitted around the irradiation portion 46 is sandwiched between the inner surface of the skin stimulating member 3 and the seal holder 51. By providing the O-ring 52, the gap between the skin stimulating body 3 and the light guide 27 can be sealed in a watertight manner. The inner surface of the O-ring 52 in this state is received by the peripheral surface of the irradiation portion 46, and even when a drop impact is applied, the O-ring 52 does not move in a radial direction, and therefore, the sealing function can be always performed in a stable state.

The rear-stage light guide 39 is fastened and fixed to the seat wall of the mounting seat 14 together with the front-stage light guide 38 in a state where the coupling tube portion 47 is engaged and coupled with the inner surface of the support tube portion 42 of the front-stage light guide 38. The head case 16 and the base portion 40 of the front-stage light guide 38 in this state are fastened to the wall of the mount 14 so as to sandwich the wall of the mount 14 therebetween, and the O-ring 52 attached to the rear-stage light guide 39 is elastically deformed by being sandwiched between the skin stimulating body 3 and the seal holder 51. Similarly, the O-ring 36 fitted to the fitting wall 34 is sandwiched by the step portion 20 of the head housing 16 and the fitting wall 34 and elastically deformed. That is, by fastening the head case 16 and the front-stage light guide 38 to the mount 14, the two O- rings 36 and 52 can be simultaneously elastically deformed, and the corresponding gaps can be sealed in a watertight manner.

As described above, the coupling cylindrical portion 47 is coupled to the support cylindrical portion 42, so that a space is formed between the front surface of the light source holder portion 41 and the rear surface of the light guide portion 45. This space functions as a diffusion space 55 for diffusing the light emitted from the light source holder portion 41, and the diffused light enters the rear-stage light guide 39 from the rear surface of the irradiation portion 46, the inner surface of the coupling cylinder portion 47, and the rear end surface and is guided to the irradiation surface 48. The light irradiated from the light source 26 is refracted while passing through the boundary surfaces of the different media, that is, the front end wall of the front stage light guide 38 and the rear end wall of the rear stage light guide 39 adjacent to the diffusion space 55, and the light is scattered while passing through the diffusion space 55. Therefore, scattering of light can be promoted, and illuminance near the center of the irradiation surface 48 and illuminance at the periphery of the irradiation surface 48 can be made uniform. Therefore, the illuminance of the light irradiated toward the skin surface can be made uniform over the entire surface of irradiation surface 48, and the cosmetic treatment can be effectively performed while applying uniform optical stimulation to the skin surface facing irradiation surface 48. Further, it is possible to eliminate the discomfort caused by the light with high illuminance entering the eyes of the user.

As shown in fig. 22, since the flat surface 48a at the peripheral edge of the irradiation surface 48 in the state where the light guide 27 and the skin stimulator 3 are integrated is flush with the skin stimulation surface 3a of the skin stimulator 3, the cosmetic treatment can be performed while the skin stimulator 3 is smoothly slid along the skin surface. In addition, when the cosmetic treatment is performed in a state where the cosmetic liquid is held on the irradiation surface 48, the cosmetic liquid remaining on the irradiation surface 48 is completely removed, and the cleaning can be easily performed. As described above, when the basic shape of the irradiation surface 48 is formed in the concave curved shape, the convex portion 49 can be omitted, and in this case, the flat surface of the peripheral edge of the irradiation surface 48 functions as the convex portion 49.

When the beauty appliance is used, a light irradiation mechanism 58 is provided on the front stage light guide 38 and the cylinder wall of the head support 15 covering the periphery thereof in order to irradiate part of the light guided by the light guide 27 toward the periphery of the light guide 27. In this embodiment, the light irradiation mechanism 58 is configured by the diffusion space 55, the inner irradiation windows (irradiation windows) 59 provided around the middle portion of the support cylinder portion 42 of the front-stage light guide 38, and the four outer irradiation windows (irradiation windows) 60 formed in the cylinder wall of the head support 15 so as to correspond to the inner irradiation windows 59. An irradiation light visual confirmation unit 21 is provided in a part of the head case 16, and light reaching the external irradiation window 60 can be visually confirmed in the irradiation light visual confirmation unit 21. In order to accurately visually confirm the light emitted toward the periphery of the light guide 27, the irradiation light visual confirmation unit 21 is disposed in a state of intersecting the optical path of the irradiation light emitted from the light irradiation mechanism 58 (in a state of facing the external irradiation window 60).

As shown in fig. 23, the inner irradiation window 59 communicates with the diffusion space 55, and a part of the light irradiated to the diffusion space 55 can be irradiated to the outside of the inner irradiation window 59. Further, the light emitted to the outside of the inside irradiation window 59 can be visually confirmed from the outer surface of the irradiation light visual confirmation part 21 through the outside irradiation window 60. In this way, if the light irradiation mechanism 58 is configured by the diffusion space 55 and the irradiation windows 59 and 60 communicating with the space 55, the light guide 27 and the head support 15 can irradiate a part of the light guided by the light guide 27 toward the periphery of the light guide 27 by securing the diffusion space 55 and the irradiation windows 59 and 60.

Therefore, compared to the case where the light irradiation mechanism 58 is configured by a structure for redirecting, reflecting, or guiding light, the structure of the light irradiation mechanism 58 can be simplified, and the cost of the beauty appliance including the light guide body 27 and the light irradiation mechanism 58 can be reduced. Further, since the diffusion space 55 and the irradiation windows 59 and 60 need only be secured, there is no room for a failure or a malfunction with respect to the function of irradiating light to the periphery of the light guide 27, and there is an advantage that reliability can be improved. Further, by making it possible to visually recognize a part of the light emitted from the light source 26 by the irradiation light visual recognition unit 21, the appearance of the skin head 2 when the beauty appliance is used can be improved, and the design can be improved. Further, by checking the color of the light that is visually checked, it can be checked which of the three LEDs 26R, 26G, 26B emits light, and the operating state of the beauty appliance can be clearly understood even when the hearing of the user is impaired.

In order to make the light radiated to the outside of the inward radiation window 59 repeatedly reflected and easily visually confirmed from the outer surface of the head case 16, a reflection layer 61 is formed on the inner surface of the cylinder wall of the head support 15 and the rear surface of the front end wall. The reflective layer 61 is formed by a metal vapor deposition method. In this way, when the reflective layer 61 is formed on the inner surface of the cylindrical wall of the support 15 and the rear surface of the front end wall, the light reaching the reflective layer 61 can be reflected toward the irradiation window 60 and the diffusion space 55, and the illuminance of the light in the irradiation light visual confirmation unit 21 can be increased.

When the cosmetic device is used, as shown in fig. 19, the outer surface of the skin irritant 3 is covered with the cotton pad M, and the cotton pad M is fixed by press-fitting the holding cap 64 to the cap fitting portion 17 of the head case 16. Since the cotton pad M in this state is impregnated with the cosmetic water, the switch button 4 is turned on, and the switch button 5 is operated to select the operation mode, the current adjusting circuit for supplying the driving current to the heater 31 to generate the pulse current is operated to be in the usable state, the user can perform the cosmetic treatment in the operation mode such as the ion introduction mode and the ion introduction mode.

(ion extraction mode) in the ion extraction mode, the cotton pad M impregnated with a cosmetic liquid such as a cosmetic water is gently slid along the face skin while the handle electrode 10 is held with one hand, whereby fine dirt such as wrinkles, creases, and pores entering the face skin can be dropped. At this time, as shown in fig. 25, current stimulation and thermal stimulation by a pulse current of positive polarity are applied to the skin surface. Further, the red LED26R and the green LED26G can be turned on to perform a cosmetic treatment while emitting yellow light to the skin surface. By irradiating the skin surface with yellow light, the skin surface can be activated to improve the cosmetic effect. By irradiating yellow light to the skin surface, the user can confirm that the cosmetic device is operating in the ion extraction mode.

When stimulation by a pulse current applied to the skin surface is weak, the amount of current can be increased by operating a switch button for switching the intensity of the current, thereby enhancing the stimulation on the skin surface. When a certain time (about 3 minutes) elapses after the pulse current is supplied to the skin stimulator 3, the supply of the pulse current is stopped, and the driving of the heater is stopped to turn off the light source 26 and the LED 9. As described above, in the ion extraction process, the cosmetic treatment is performed with the skin stimulator 3 side as a positive polarity and the handle electrode 10 side as a negative polarity. As described above, in the case of performing the cosmetic treatment, the cotton pad M is attached to the skin stimulator 3, but since the holding cap 64 is attached to the cap attaching portion 17 on the periphery of the protruding end of the head case 16, the irradiated light visual confirmation portion 21 can be prevented from being covered with the cotton pad M. Therefore, if the cotton pad M is used simultaneously to perform the cosmetic treatment, the light source 26 emits light, and the irradiation light visual confirmation unit 21 can confirm that the cosmetic device is in operation. Further, since the cosmetic treatment can be performed while the skin irritant 3 is heated by the heater 31, when the ion extraction treatment is performed in a cold season or when the skin irritant 3 is brought into direct contact with the skin surface to perform the cosmetic treatment, the skin irritant 3 is heated by the heater 31, and thus the cosmetic treatment can be performed comfortably without feeling cold of the cosmetic liquid or the skin irritant 3. Further, since the skin irritant 3 or the cotton pad M is heated by the heater 31 while the cosmetic treatment is being performed, the skin surface can be heated warm and relaxed while the cosmetic water is impregnated into the skin surface, and the cosmetic treatment can be effectively performed.

(ion introduction mode) in the ion introduction mode, the cotton pad M impregnated with the cosmetic liquid such as cosmetic water is gradually slid along the skin of the face in a state where the handle electrode 10 is held with one hand as in the ion introduction mode, whereby the cosmetic liquid can be impregnated into the skin surface to improve the moisturizing effect. At this time, as shown in fig. 25, thermal stimulation by the heater 31 is applied to the skin surface, and a pulse current of negative polarity is supplied to the skin stimulator 3 and a pulse current of positive polarity is supplied to the handle electrode 10. Then, the red LED26R is turned on to perform cosmetic treatment while emitting red light to the skin surface. By irradiating the skin surface with red light in this manner, the skin surface can be activated to improve the cosmetic effect. By irradiating the skin surface with red light, the user can confirm that the cosmetic device is operating in the ion extraction mode. When a certain time (about 3 minutes) has elapsed since the pulse current was supplied to the skin stimulator 3, the supply of the pulse current is stopped, and the light source 26 and the LED9 are turned off. In the iontophoresis treatment, the skin irritant 3 may be gently slid along the skin surface in a state in which a cosmetic liquid such as a cosmetic water is applied to the face skin without using the cotton pad M. In the iontophoresis mode, the skin irritant 3 and the cotton pad M are heated by the heater 31 while the cosmetic treatment is performed, so that the skin surface can be heated and loosened while the cosmetic water is permeated to the skin surface, and the moisturizing effect can be improved.

(third mode) in the third mode, the skin-stimulating body 3 is slid gently along the skin surface in a state where the facial skin is covered with the mask or in a state where the lotion is applied to the irradiation surface 48 without using the cotton pad M, and thereby the cosmetic treatment is performed. In the third mode, as shown in fig. 25, thermal stimulation is applied by the heater 31, a pulse current of positive polarity and a pulse current of negative polarity are alternately supplied to the skin stimulator 3, and the skin surface is finished by performing cosmetic treatment while the red LED26R is blinking. In this way, by performing cosmetic treatment with the red LED26R blinking, skin cells are activated, and the cosmetic effect can be improved. Further, it can be confirmed that the cosmetic device is operated in the third mode since the red LED26R blinks. In a state where the red LED26R is turned on, the green LED26G may be turned on intermittently to generate yellow light, thereby performing a cosmetic treatment. When a certain time (about 3 minutes) has elapsed since the pulse current was supplied to the skin stimulator 3, the supply of the pulse current is stopped, and the light source 26 and the LED9 are turned off.

As described above, in the cosmetic device of example 4, the skin surface is activated to improve the cosmetic effect as compared with the conventional cosmetic device, since the cosmetic treatment is performed while applying the thermal stimulation to the skin surface and supplying the electric current and irradiating the light. Specifically, the skin cells on the skin surface are activated by irradiating the skin surface with light, and the metabolism of the skin cells can be promoted. The physiological mechanism for activating skin cells by irradiating red light or yellow light to the skin surface is unknown, but a cosmetic device provided with a light source has been developed, and cosmetic treatment using light together is expected to become widespread in the future based on findings confirmed in the course of actually performing a skin treatment test (japanese patent application laid-open No. 2011-41706). As the light source 26 for irradiating the skin surface, a near infrared LED may be used as the light source 26 in addition to the visible light type light source 26. In this case, in each of the operation modes described above, the near infrared LED may be turned on to perform the cosmetic treatment, or may be used together with the visible light-type light source 26 to perform the cosmetic treatment.

In a state where the head housing 16 and the light guide 27 are assembled to the main body housing 1, the O-ring 52 is in close contact with the seal holder 51 and the inner surface of the skin irritant 3 in an elastically deformed state, and the O-ring 36 is in close contact with the step portion 20 and the fitting wall 34 in an elastically deformed state. Therefore, even if a cosmetic liquid such as a cosmetic water is immersed along the window opening 35 and the peripheral wall of the skin irritant 3, the cosmetic liquid can be sealed by the O- rings 52 and 36, and the cosmetic water can be prevented from entering the skin irritant 3 and the interior of the head housing 16. Therefore, accidents such as short-circuiting of the heater 31 and the spring 32 caused by the immersion of the cosmetic liquid can be eliminated, and the safety and reliability of the cosmetic device can be improved. Further, since the skin irritant 3 and the attachment wall 34 press the O- rings 52, 36 in a state in which the O- rings 52, 36 are elastically deformed, the skin irritant 3 can be prevented from loosening, and even if there is a difference in finished dimensions of the skin irritant 3 and the head housing 16, the difference can be absorbed by the O- rings 52, 36.

(embodiment 5) fig. 26 shows embodiment 5 in which the structure of the irradiation surface 48 is changed. Here, the irradiation surface 48 is formed of a flat surface, and is provided with the same convex portion 49 and concave portion 50 as in example 4. In a state where the light guide 27 is assembled to the skin irritant 3, the peripheral edge of the irradiation surface 48 is located within the thickness range of the window opening 35, and the top of the projection 49 is flush with the stimulation surface 3a of the skin irritant 3. As described above, if the irradiation surface 48 is formed of a flat surface, the depression depth of the concave portion 50 on the irradiation surface 48 can be made constant as compared with the light guide 27 of example 4, and more cosmetic liquid can be held on the irradiation surface 48. Further, when the skin irritant 3 is gently slid along the skin surface to perform the cosmetic treatment, it is possible to prevent the irradiation surface 48 from being unnecessarily strongly pressed against the skin surface, and to make the skin of the skin irritant 3 gently and gently contact. Further, by positioning the irradiation surface 48 within the thickness range of the window opening 35, the irradiation surface 48 is brought into close contact with the skin surface, and the light emitted from the light source 26 can be effectively irradiated to the skin surface. Otherwise, the same components as those in embodiment 4 are denoted by the same reference numerals, and descriptions thereof are omitted. The same applies to the following examples.

(embodiment 6) fig. 27 shows embodiment 6 in which the structure of the irradiation surface 48 is changed. Here, the projection portions 49 in an endless ring shape are doubly formed on the irradiation surface 48, and the recessed portions 50 in an endless groove shape are formed on the inner surface of each projection portion 49. Thus, if the concave portion 50 is formed in an endless groove shape, the cosmetic liquid can be held in the concave portion 50 at the center and near the peripheral edge of the irradiation surface 48, and the cosmetic liquid can be prevented from being held in a state of being biased to a part of the irradiation surface 48.

(embodiment 7) fig. 28 shows embodiment 7 in which the structure of the irradiation surface 48 is changed. Here, the irradiation surface 48 is formed of a flat surface, hemispherical recesses 50 are formed in the center and six places around the irradiation surface, and the adjacent recesses 50 function as projections 49. In this embodiment, the peripheral edge of the hemispherical recess 50 is in contact with the skin surface in a state where the irradiation surface 48 is pressed against the skin surface, so that the skin of the face can be stimulated by friction to improve the cosmetic effect. Furthermore, by performing the cosmetic treatment in a state where the cosmetic liquid is held only in a part of the concave portion 50, unnecessary application of the cosmetic liquid to the skin surface can be suppressed, and the cosmetic liquid can be applied in a well-balanced manner.

(embodiment 8) fig. 29 shows embodiment 8 in which the structures of the light guide 27 and the light irradiation mechanism 58 are changed. Here, the light guide 27 is configured by a single part by integrating a portion corresponding to the front stage light guide 38 and a portion corresponding to the rear stage light guide 39 in embodiment 4. Specifically, the light guide portion 45 having a circular shaft shape is provided continuously with the light source holder portion 41, and the irradiation portion 46 is provided at the tip end thereof, so that the diffusion space 55 is omitted. The light irradiation mechanism 58 is configured by an irradiation recess 68 formed in a concave manner on the peripheral surface of the light guide portion 45 of the light guide 27 and a circular-axis-shaped irradiation rib 69 provided on the light incident surface 70 side of the irradiation recess 68.

The irradiation recesses 68 and the irradiation ribs 69 are formed at four positions on the peripheral surface of the light guide unit 45, and the projecting ends of the irradiation ribs 69 are flat surfaces and face the outer irradiation windows 60. The irradiation recess 68 is inclined in a state of being inclined downward toward the light source 26 with respect to the central axis of the light guide unit 45, and the light reaching the light incident surface 70 from the light source 26 can be reflected toward the irradiation rib 69. This allows the light guided by the light guide unit 45 to be emitted toward the periphery of the light guide 27. In this way, a part of the light emitted from the light source 26 to the light guide body 27 is reflected and redirected by the light incident surface 70, and can be emitted to the irradiation light 60 directly facing the irradiation light visual confirmation unit 21. Further, since the light reflected and redirected by the light incident surface 70 is guided to the vicinity of the irradiation window 60 by the irradiation rib 69 and is irradiated, the amount of light scattered from the light irradiation mechanism 58 until reaching the irradiation window 60 can be reduced, and the irradiation light visual confirmation unit 21 can be made to emit light more clearly.

(embodiment 9) fig. 30 shows embodiment 9 in which the structure of the light irradiation mechanism 58 is changed. Here, the light guide 27 is constituted by one component as in embodiment 8, and the light irradiation mechanism 58 is constituted by the irradiation concave portion 68 and the external irradiation window 60 which are formed at four positions on the peripheral surface of the light guide portion 45 facing the external irradiation window 60. According to the light irradiation mechanism 58, the light irradiated from the light source to the light guide body 27 and incident on the irradiation concave portion 68 can be reflected on the light reflection surface 71 and can be irradiated toward the periphery of the light guide body 27. Specifically, since the light incident on the irradiation recess 68 can be reflected by the light reflecting surface 71 and irradiated to the irradiation window 60 directly facing the irradiation light visual confirmation unit 21, the irradiation light visual confirmation unit 21 can be caused to emit more clear light than in the case where the light reaches the irradiation window 60 by the scattering action, and the use of the cosmetic device can be accurately reported.

(embodiment 10) fig. 31 shows embodiment 10 in which the structures of the light guide 27 and the light irradiation mechanism 58 are changed. Here, the front-rear thickness of the light source holder portion 41 of the front-stage light guide 38 is reduced, and the light emitting surfaces of the LEDs 26R, 26G, and 26B mounted on the mounting portion 43 of the light source holder portion 41 are exposed to the diffusion space 55. Further, a portion corresponding to the support cylinder portion 42 is formed by four cylinder frames 42a continuous with the light source holder portion 41, and diffusion plates 73 made of a light transmitting material are arranged in front and rear of the inside thereof. The light emitted from the light source 26 is diffused every time the front and rear diffusion plates 73 pass through, and is irradiated to the periphery of the light-guiding body 27 from the inner irradiation window 59 between the barrel frames 42a adjacent in the circumferential direction. The front-rear length of the coupling tube portion 47 of the rear-stage light guide 39 is shorter than the coupling tube portion 47 of example 4.

(example 11) fig. 32 and 33 show example 11 in which the structure of the light guide 27 is changed. Here, the light guide 27 is formed of one component, and has a light source holder 41 formed at a rear end thereof in a recessed manner, and a light guide portion 45 provided on a front side of the light source holder 41. A flange portion 74 extends around the light source holder portion 41, and the flange portion 74 is fastened and fixed to the front end wall of the head support 15 by screws 75. A metal light shielding plate 76 is fixed to the center of the front surface of the irradiation portion 46, and an annular irradiation surface 48 is provided around the light shielding plate 76. The irradiation surface 48 is formed by a concave curved surface having a concave shape at the back and can hold the cosmetic liquid.

The light source 26 includes an LED substrate 77 and three full-color LEDs 26C mounted on the substrate 77, and the LED substrate 77 is fixed to the peripheral wall of the light source holder 41 with the full-color LED26C facing the rear surface of the light guide part 45. In this embodiment, the light emitted from the light source 26 cannot be irradiated to the periphery of the light guide 27, but by arranging an LED dedicated for visual confirmation that emits light in synchronization with the light emission operation of the light source 26 inside the external irradiation window 60 in advance, the light emission state of the LED dedicated for visual confirmation can be visually confirmed in accordance with the use state of the beauty appliance.

(example 12) fig. 34 shows example 12 in which a part of the light guide 27 of example 11 is modified. Here, the light shielding plate 76 is formed integrally with the skin stimulation surface 3a of the skin stimulator 3, and the light shielding plate 76 and the skin stimulation surface 3a are connected by four bridging arms 78 in an X shape. In this way, the irradiation surface 48 does not need to be formed in an endless ring shape, and may be provided intermittently.

(embodiment 13) fig. 35 shows an embodiment 13 of a beauty appliance in which a light source 26 and a camera 81 are disposed inside a light guide 27. Here, a quasi-telephoto lens body (conversion lens) 82 and a camera holder 83 are fixed to a front end wall of the head support 15, and a front surface of the lens body 82 is covered with a transparent protective cover 84. The camera 81 is fixed to the center of the camera holder 83 so as to face the lens body 82, and a plurality of Light Sources (LEDs) 26 are provided around the camera holder. The lens body 82 is formed of a plastic lens integrally including a lens body 85 and a support frame portion 86 for supporting the lens body 85, and the support frame portion 86 and the camera holder 83 are fastened to the front end wall of the head support body 15 by screws 87. Reference numeral 52 denotes an annular gasket corresponding to the O-ring 52 of example 4.

When the beauty appliance is used, the camera 81 photographs the state of the skin surface while irradiating light from the light source 26, thereby obtaining abnormalities of the skin surface, such as pigmentation including color spots, dark spots, and the like, and pigmentation including freckles, and the like, as images. The image acquired by the camera 81 is sent to a determination unit (skin abnormality detection unit) 88 provided on the control board 7, and the presence or absence of the pigmented spots or deposits is determined in real time. When an abnormality of the skin surface such as a pigmented spot or a pigmentation is confirmed, a speaker (a reporter) 89 is operated to emit a warning sound to notify the user that there is an abnormality of the skin surface. The user who hears the warning sound confirms the content and the position of the abnormality on the skin surface, and performs treatment for making color spots, dullness, freckles, etc. inconspicuous, or performs skin care such as application of a cosmetic liquid containing a medicinal component.

As described above, according to the beauty appliance of example 13, it is possible to report to the user that color spots, dullness, freckles, and the like are generated on the skin surface at an early stage in parallel with the cosmetic treatment. Further, by detecting skin abnormality and also performing ion introduction by the skin irritant 3 to skin abnormal portions such as color spots and darkness, it is possible to accurately perform a process for masking the skin abnormal portions.

In example 13, the speaker 89 is used as the report body, but the report body 89 may be configured by a light emitting body or a vibration generating device in addition to sound. If necessary, the report body 89 can be configured by combining a plurality of report elements of sound, light, and vibration. In this case, the light source 26 may also serve as the reporter 89, and the occurrence of skin abnormality on the skin surface can be clearly reported by blinking the irradiation light visual confirmation unit 21 or changing the color of the light irradiated from the light source 26. Furthermore, when a skin abnormality is found, the current for iontophoresis is automatically increased, and the cosmetic effect accompanying iontophoresis is enhanced, whereby the skin abnormality can be effectively eliminated. In this case, the output current to the skin stimulator 3 can be automatically increased while the skin abnormality is found, and the user's effort and time for switching can be saved. When the normal skin care current is 1, the current after enhancement due to skin abnormality may be about 1.2. When the cosmetic treatment is performed while light is being emitted from the light source 26, the current to be supplied to the skin stimulator 3 may be 0 or 0.5, and the current after the enhancement due to the skin abnormality may be 1. The light source 26 may be configured to emit light for treatment, and the light emission intensity of the light source 26 for emitting light for treatment may be increased in a state where the skin abnormality detection unit 88 detects abnormality on the skin surface, thereby improving the treatment effect.

As described above, when the light emission intensity of the light source 26 is increased in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface, the skin abnormality is detected and the intensity of the light for treatment is increased, so that the treatment effect is increased and the skin abnormality can be effectively reduced. The light emission intensity of the light source 26 in the case of performing the cosmetic treatment may be such that the camera 81 can capture an image of the skin abnormality, and the healthy skin surface is not damaged by the light for treatment.

The beauty appliance of example 13 can be implemented as follows.

A cosmetic device having a skin electrode 3 capable of supplying an electric current to a skin surface, comprising:

a skin abnormality detection unit 88 for detecting abnormality on the skin surface; and

the report body 89 generates at least one of sound, light, and vibration in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface.

According to the beauty appliance having the above-described configuration, the current is supplied from the skin electrode 3 to the skin surface to perform the beauty treatment, and in parallel with this, the skin abnormality detecting unit 88 detects the occurrence of color spots, dullness, freckles, and the like on the skin surface, and the reporter 89 can report the occurrence of the color spots, dullness, freckles, and the like to the user. The user who hears the warning sound can specify the content and the position of the abnormality on the skin surface, and can perform treatment for making color spots, dullness, freckles, and the like inconspicuous, or perform skin care such as applying a cosmetic liquid containing a medicinal component. Further, when the skin abnormality is detected and the skin irritant 3 introduces ions into the skin abnormality such as color spots or darkness, the treatment for masking the skin abnormality can be accurately performed.

In the cosmetic device described above, the output current of the skin electrode 3 is increased in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface.

According to the cosmetic device, when the current for iontophoresis is automatically increased while skin abnormality is detected, the cosmetic effect associated with iontophoresis can be enhanced, and skin abnormality can be gradually improved. Further, the output current to the skin stimulator 3 can be automatically increased while the skin abnormality is found, and the user's labor and time for switching can be saved.

In this case, the light guide 27 can be formed of a conductive resin, and in this case, the skin stimulator 3 and the light guide 27, which supply current to the skin surface, can supply current to a skin surface having a larger area than in the case where current is supplied to the skin surface only by the skin stimulator 3, and thus the cosmetic treatment can be performed effectively.

In example 4, red or yellow light is irradiated to the skin surface, but this is not essential, and the cosmetic treatment may be performed while illuminating all of the LEDs 26R, 26G, and 26B and irradiating white light (visible light) to the skin surface. In addition, the cosmetic treatment can be performed by lighting only the green LED26G or only the blue LED26B, and in short, the color of light to be irradiated to the skin surface may be any color as long as the color of light can effectively perform the cosmetic treatment. The light source 26 for irradiating the skin surface may be a light source for irradiating ultraviolet light of a specific wavelength for skin treatment, in addition to a visible light type or near infrared light type light source. The cosmetic device may further include a second skin stimulator for applying cold or heat to the skin surface. The light source 26 need not be constituted by three shell-shaped single-color LEDs, and may be constituted by one or more chip-type white LEDs. The head housing 16 may be formed integrally with the main body housing 1.

The beauty treatment instrument according to embodiment 4 can be implemented as follows.

A beauty appliance comprising a skin stimulator 3 which comes into contact with the skin surface and supplies an electric current, and a light source 26 for irradiating the skin surface with light,

a light guide 27 for guiding the light emitted from the light source 26 to the outside of the window opening 35 is disposed between the window opening 35 opened in the skin stimulator 3 and the light source 26,

the gap between the skin stimulator 3 and the light guide 27, which communicates the inside and the outside of the skin stimulator 3 with each other through the window opening 35, is sealed in a watertight manner by the first seal 52 disposed between the skin stimulator 3 and the light guide 27.

The beauty appliance of the present invention is provided with a skin stimulator 3 which is in contact with the skin surface and supplies an electric current, and a light source 26 which irradiates the skin surface with light. Further, a light guide 27 is disposed between the window opening 35 opened to the skin stimulator 3 and the light source 26, and light emitted from the light source 26 can be guided by the light guide 27 and be emitted to the outside of the skin stimulator 3. According to such a beauty treatment apparatus, when the beauty treatment apparatus is used, by turning on the light source 26 in advance, it is possible to perform a beauty treatment while illuminating the skin surface with the light emitted from the light guide 27. Further, since the gap between the skin irritant 3 and the light guide 27 is sealed in a watertight manner by the first sealing body 52, when the cosmetic treatment is performed by using the cosmetic liquid at the same time, the cosmetic liquid can be reliably prevented from infiltrating into the skin irritant 3, and accidents such as short-circuiting caused by infiltration of the cosmetic liquid can be prevented, thereby improving the safety and reliability of the cosmetic device.

In the cosmetic device, an irradiation portion 46 that enters the inner surface of the window opening 35 is provided at the end portion of the light guide 27 on the window opening 35 side in a protruding manner, and an irradiation surface 48 that irradiates the light emitted from the light source 26 toward the skin surface is provided at the protruding end,

a seal seat 51 for sandwiching an annular first seal 52 is formed around the projecting proximal end of the irradiation portion 46,

the first sealing body 52 sandwiched between the sealing seat 51 and the inner surface of the skin irritant substance 3 is received by the circumferential surface of the irradiation portion 46, and the displacement movement of the first sealing body 52 is restricted.

When the first sealing body 52 is sandwiched between the seal holder 51 provided around the projecting base end of the irradiation portion 46 and the inner surface of the skin irritant 3 and the first sealing body 52 is received by the circumferential surface of the irradiation portion 46, the first sealing body 52 can be restricted from moving away in the radial direction. Therefore, even when a drop impact is applied to the skin head 2, the first sealing body 52 does not move in the radial direction, and therefore, the sealing action can always be performed in a stable state, and the cosmetic liquid can be more reliably prevented from entering the skin irritant 3.

In the beauty appliance described above, the irradiation surface 48 is located within the thickness range of the window opening 35.

When the irradiation surface 48 is located within the thickness range of the window opening 35, when the skin stimulating body 3 is gradually slid along the skin surface to perform the cosmetic treatment, the irradiation surface 48 can be prevented from being unnecessarily strongly pressed against the skin surface, and the skin of the skin stimulating body 3 can be gently and gently contacted. Further, by positioning the irradiation surface 48 within the thickness range of the window opening 35, the irradiation surface 48 can be brought into close contact with the skin surface, and the light emitted from the light source 26 can be effectively irradiated to the skin surface.

In the cosmetic device described above, the light guide 27 is fixed in a state where the peripheral edge of the irradiation surface 48 is flush with the stimulation surface 3a of the skin stimulator 3.

When the peripheral edge of the irradiation surface 48 is flush with the skin stimulation surface 3a of the skin stimulator 3 in the state where the light guide 27 is fixed, the skin stimulator 3 can smoothly slide along the skin surface to perform the cosmetic treatment. Further, since the peripheral edge of the irradiation surface 48 is flush with the skin irritation surface 3a, when the cosmetic liquid adhering to the irradiation surface 48 is removed after the cosmetic treatment, the cosmetic liquid does not stay on the inner edge of the window opening 35, and therefore the cosmetic liquid adhering to the irradiation surface 48 can be completely wiped off or reliably washed with water.

In the beauty appliance described above, a head case 16 for supporting the skin stimulating body 3 is provided to protrude from the main body case 1, and the skin stimulating body 3 is arranged at the protruding end of the head case 16,

the first sealing body 52 disposed between the skin irritant 3 and the light guide 27 is pressed against the skin irritant 3 by the light guide 27 fixed to the main body case 1, thereby sealing the gap between the skin irritant 3 and the light guide 27.

When the skin stimulating body 3 is disposed at the projecting end of the head case 16 and the first sealing body 52 disposed between the skin stimulating body 3 and the light guide body 27 is pressed against the skin stimulating body 3 by the light guide body 27 fixed to the main body case 1, the first sealing body 52 can be elastically deformed by merely assembling the light guide body 27 to the main body case 1, and the gap between the skin stimulating body 3 and the light guide body 27 can be sealed, and the light guide body 27 can be assembled to the main body case 1 with less labor and time.

In the cosmetic device, the skin irritant 3 protrudes from the front opening 19 provided at the protruding end of the head case 16, the second sealing body 36 is arranged between the mounting wall 34 provided on the skin irritant 3 and the step portion 20 provided on the inner surface of the front opening 19,

In a state where the light guide 27 is fixed to the main body case 1, the fitting wall 34 and the second sealing body 36 of the skin stimulator 3 are pressed and fixed toward the stepped portion 20.

If the second sealing body 36 is disposed between the mounting wall 34 provided on the skin stimulator 3 and the step portion 20 provided on the inner surface of the front opening 19, the mounting wall 34 of the skin stimulator 3 and the second sealing body 36 can be pressed and fixed toward the step portion 20 in a state where the light guide 27 is fixed to the main body housing 1. Further, as described above, by fixing the light guide 27 to the main body case 1, the two sealing bodies 36 and 52 can be sandwiched at the same time to maintain the sealing posture, and the labor and time required for assembly can be saved.

In the cosmetic device, the light source 26 disposed inside the inner surface of the head case 16 faces the window opening 35 through the light adjustment space S,

a light guide 27 is disposed in the light adjustment space S between the light source 26 and the window opening 35.

When the light guide 27 is disposed in the light adjustment space S between the light source 26 and the window opening 35, the light emitted from the light source 26 is repeatedly scattered inside the light guide 27, and then can be irradiated from the irradiation surface 48 to the skin surface. As described above, by repeatedly scattering light in the light guide 27, the illuminance at the center of the irradiation surface 48 facing the light source 26 and the illuminance at the periphery of the irradiation surface 48 can be made uniform. Therefore, the illuminance of the light irradiated toward the skin surface can be made uniform over the entire irradiation surface 48, and the irradiation of the light of the portion with high illuminance can be eliminated without causing the user to feel uncomfortable.

In the beauty appliance described above, the irradiation surface 48 is formed by a concave curved surface that is concave toward the inner surface of the skin irritant 3.

If the irradiation surface 48 is formed in a concave curved surface shape, the beauty treatment can be performed in a state where the beauty treatment liquid is held on the concave surface of the irradiation surface 48. Further, when the cosmetic treatment is performed while sliding the skin stimulating body 3 along the skin surface, the cosmetic liquid held on the concave surface of the irradiation surface 48 can be applied little by little, and the labor and time for applying the cosmetic liquid to the skin surface a plurality of times can be saved, so that the cosmetic treatment can be performed more easily.

In the beauty appliance, at least one convex portion 49 and at least one concave portion 50 are formed on the inner concave irradiation surface 48.

When the convex portion 49 and the concave portion 50 are formed on the irradiation surface 48, the cosmetic liquid adhering to the concave surface of the irradiation surface 48 can be cooperatively held by the convex portion 49 and the concave portion 50, and the cosmetic liquid can be prevented from excessively adhering to the skin surface and can be uniformly applied to the skin surface. When the cosmetic liquid is applied, the skin surface can be illuminated by irradiating light from the convex portion 49 to the skin surface at all times. In addition, since the friction stimulus can be applied by the convex portion 49 in contact with the skin of the face when the cosmetic treatment is performed, the cosmetic effect by the friction stimulus can be exhibited in addition to the cosmetic effect by the skin stimulator 3.

In the cosmetic device described above, the projection 49 provided on the irradiation surface 48 is formed in a ring shape, and the recess 50 is formed on the inner surface of the ring of the projection 49.

If the convex portion 49 is formed in an annular shape and the concave portion 50 is formed on the inner surface of the ring of the convex portion 49, the cosmetic liquid held in the concave portion 50 can be prevented from adhering to the skin surface and being applied by the annular convex portion 49. Therefore, the cosmetic liquid can be applied more uniformly to the skin surface. Further, the cosmetic treatment can be accurately performed while visually checking the light emitted from the annular convex portion 49 toward the skin surface. Further, there is also an advantage that the cosmetic effect can be improved by applying the rubbing stimulation to the facial skin by the annular convex portion 49.

In the beauty appliance, the light guide 27 is formed of a plastic molded product containing a filler 65 having a light diffusing effect.

If the light guide 27 is formed of a plastic molded product containing the filler 65 having a light diffusion effect, the filler 65 can promote a scattering effect of light inside the light guide 27, and the illuminance of light irradiated toward the skin surface can be made uniform without unevenness. Therefore, a more uniform light can be irradiated to the skin surface facing the irradiation surface 48, and the irradiation of light at a portion with high illuminance can be eliminated.

In the beauty appliance, a diffusion space 55 for diffusing light emitted from the light source 26 is formed inside the light guide 27.

When the diffusion space 55 is formed inside the light guide 27, the light emitted from the light source 26 is refracted when passing through the boundary surface of different media, that is, the wall portion of the light guide 27 adjacent to the diffusion space 55, and the light is scattered when passing through the diffusion space 55. Therefore, scattering of light can be promoted, the illuminance of light irradiated from irradiation surface 48 toward the skin surface can be further made uniform, and irradiation of light at a portion with high illuminance can be further reliably eliminated.

In the beauty appliance, at least a part of the head housing 16 is provided with a visual confirmation part 21 of irradiation light which can transmit,

a light irradiation mechanism 58 for irradiating a part of the light guided by the light guide 27 to the periphery of the light guide 27 is provided in the middle of the light guide 27,

the light emitted from the light irradiation mechanism 58 can be visually confirmed from the outside of the head housing 16 through the irradiation light visual confirmation unit 21.

According to the cosmetic device provided with the light irradiation mechanism 58 for irradiating a part of the light guided by the light guide 27 to the periphery of the light guide 27 and the head case 16 provided with the irradiation light visual confirmation unit 21, a part of the light irradiated from the light irradiation mechanism 58 can be visually confirmed from the outside of the head case 16 via the irradiation light visual confirmation unit 21. Therefore, the appearance of the skin head 2 when the beauty appliance is used can be improved, and the design can be improved. When the cosmetic treatment is performed while light of a predetermined color is irradiated onto the skin surface, the color of the light at the irradiated light visual confirmation unit 21 is visually confirmed, whereby the content of the cosmetic treatment can be confirmed. Further, by visually confirming that the irradiation light visual confirmation unit 21 emits light, it can be confirmed that the cosmetic device is in operation, and even when the hearing of the user is impaired, the operating state of the cosmetic device can be clearly understood.

In the beauty treatment device, the light guide body 27 is formed of conductive resin,

the skin stimulator 3 also serves as a skin electrode for supplying current to the skin surface, and supplies current to the skin stimulator 3 and the light guide 27 to perform cosmetic treatment.

When the light guide 27 is formed of a conductive resin and current is supplied to the skin stimulator 3 serving also as a skin electrode and the light guide 27 to perform cosmetic treatment, current can be supplied to the skin surface from both the skin stimulator 3 and the light guide 27, and current can be supplied to a skin surface having a larger area than a case where current is supplied to the skin surface from only the skin stimulator 3, and cosmetic treatment can be performed effectively.

In the cosmetic device described above, the light irradiation mechanism 58 is composed of: a diffusion space 55 that diffuses light irradiated from the light source 26; and irradiation windows 59 and 60 communicating with the space 55 and irradiating the light diffused by the diffusion space 55 toward the periphery of the light guide 27.

When the light irradiation mechanism 58 is configured by the diffusion space 55 and the irradiation windows 59 and 60 communicating with the diffusion space 55, the diffusion space 55 and the irradiation windows 59 and 60 are secured in the light guide 27 and the head support 15, and a part of the light guided by the light guide 27 can be irradiated to the periphery of the light guide 27. Therefore, compared to the case where the light irradiation mechanism 58 is configured by a structure for redirecting, reflecting, or guiding light, the structure of the light irradiation mechanism 58 can be simplified, and the cost of the beauty appliance including the light guide body 27 and the light irradiation mechanism 58 can be reduced. Further, since the diffusion space 55 and the irradiation windows 59 and 60 need only be secured, there is no room for a failure or malfunction in the function of irradiating light toward the periphery of the light guide 27, and there is an advantage that reliability can be improved.

In the beauty appliance, the light irradiation mechanism 58 is constituted by the irradiation concave portion 68 formed to be concave in the peripheral surface of the light guide 27.

According to the light irradiation mechanism 58 including the irradiation recess 68 formed recessed in the peripheral surface of the light guide 27, the light which is irradiated from the light source to the light guide 27 and enters the irradiation recess 68 can be irradiated toward the periphery of the light guide 27. Specifically, the light incident on the irradiation recess 68 can be irradiated to the irradiation light visual confirmation unit 21, and the irradiation light visual confirmation unit 21 can be made to emit light with more clear light than in the case where the light reaches the irradiation window 60 by the scattering action, and the beauty appliance can be accurately notified of being in use. In particular, when the light reflecting surface 71 is provided in the irradiation recess 68, the light incident on the irradiation recess 68 can be reliably reflected toward the irradiation window 60, and thus more intense light can be irradiated to the irradiation light visual confirmation unit 21.

In the cosmetic device described above, the light irradiation mechanism 58 is composed of: an irradiation recess 68 formed concavely on the peripheral surface of the light guide 27; and an irradiation rib 69 provided on the light incident surface 70 side of the irradiation recess 68 and configured to irradiate the light guided by the light guide 27 toward the periphery of the light guide 27.

When the light irradiation mechanism 58 is configured by the irradiation concave portion 68 and the irradiation rib 69 provided on the light incident surface 70 side thereof, the direction of a part of the light irradiated from the light source 26 to the light guide 27 is reflected and changed by the light incident surface 70, and thereafter, the light can be irradiated to the irradiation light visual confirmation unit 21. Further, since the light reflected and redirected by the light incident surface 70 can be guided to the vicinity of the irradiation window 60 by the irradiation rib 69 and irradiated, the amount of light scattered from the light irradiation mechanism 58 to the irradiation window 60 can be reduced, and the irradiation light visual confirmation unit 21 can be made to emit light more clearly.

In the cosmetic device, the head case 16 is fixed to the head support 15 provided in the case 16,

the light guide 27 is disposed inside the head support 15, and the periphery of the light guide 27 is surrounded by the cylinder wall of the head support 15,

a reflection layer 61 for reflecting light emitted from the light irradiation mechanism 58 is formed on the inner surface of the head support 15 including the cylindrical wall thereof.

When the reflective layer 61 that reflects the light emitted from the light irradiation mechanism 58 is formed on the inner surface of the head support including the cylindrical wall of the head support 15, the light reaching the reflective layer 61 is reflected toward the irradiation window 60 and the diffusion space 55, and the illuminance of the light at the irradiation light visual confirmation unit 21 can be increased.

In the cosmetic device, at least a part of the head case 16 is provided with an irradiation light visual confirmation part 21 formed of a light transmitting material,

the irradiation light visual confirmation unit 21 is disposed in a state of intersecting the optical path of the irradiation light irradiated from the light irradiation mechanism 58.

If the irradiation light visual confirmation unit 21 formed of a light transmitting material is provided at least in part of the head case 16, the appearance of the skin head 2 can be made neat, and the design of the cosmetic device can be improved, as compared with the case where a window is opened in the head case 16 as the irradiation light visual confirmation unit 21. Further, by arranging the irradiation light visual confirmation unit 21 in a state of intersecting the optical path of the irradiation light irradiated from the light irradiation mechanism 58 in advance, the illuminance at the irradiation light visual confirmation unit 21 can be increased, and it is possible to clearly notify the user that the cosmetic device is in operation.

In the beauty treatment instrument described above, the holding cap 64 for fixing the cotton pad M is detachably attached to the cap attaching portion 17 provided on the peripheral edge of the protruding end of the head case 16.

If the cap mounting portion 17 for mounting the holding cap 64 for the cotton pad M is provided on the periphery of the projecting end of the head case 16, the light source 26 can be made to emit light when the cosmetic treatment is performed by using the cotton pad M at the same time by preventing the irradiation light visual confirmation portion 21 from being covered with the cotton pad M in a state where the cotton pad M is mounted on the skin irritant 3, and it can be confirmed that the cosmetic device is in operation by the irradiation light visual confirmation portion 21.

In the beauty appliance described above, the heater 31 for heating the skin irritant 3 is disposed on the inner surface of the skin irritant 3 facing the periphery of the light guide 27.

If the heater 31 is disposed on the inner surface of the skin stimulating body 3 facing the periphery of the light guide 27, the skin stimulating body 3 can be heated by the heater 31 while being subjected to the beauty treatment. In particular, by performing the iontophoresis treatment while heating the skin irritant 3 or the cotton pad M by the heater 31, the skin surface can be heated and loosened while the cosmetic solution is permeated into the skin surface. Further, even when the iontophoresis treatment is performed in a cold season or the skin irritant 3 is brought into direct contact with the skin surface to perform the cosmetic treatment, the skin irritant 3 is heated by the heater 31, so that the cosmetic liquid and the skin irritant 3 do not become cold, and the cosmetic treatment can be performed comfortably.

In the beauty treatment device, the light source 26 and the camera 81 for imaging the state of the skin surface are arranged inside the light guide 27,

the following components are provided inside the main body case 1: a skin abnormality detection unit 88 for detecting abnormality on the skin surface based on the image captured by the camera 81; and a report body 89 for generating at least one of sound, light, and vibration in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface.

According to the beauty appliance in which the light source 26 and the camera 81 are disposed inside the light guide 27 and the skin abnormality detection section 88 and the reporter 89 are provided inside the main body case 1, it is possible to report to the user that color spots, dullness, freckles, and the like are generated on the skin surface at an early stage in parallel with the beauty treatment. Furthermore, the skin care appliance can detect skin abnormality and can introduce ions by the skin irritant 3.

In the cosmetic device, the light source 26 also serves as the report body 89,

in a state where the skin abnormality detection unit 88 detects abnormality on the skin surface, light is irradiated from the light source 26.

According to the cosmetic device in which the light source 26 also serves as the reporter 89 and the skin abnormality detection unit 88 detects an abnormality on the skin surface and irradiates light from the light source 26, for example, the occurrence of a skin abnormality on the skin surface can be notified by blinking the light source 26 or changing the light emission color of the light source 26. Further, since it is not necessary to separately provide a light source and a sound emitting mechanism dedicated for the report, the cost required for manufacturing the beauty appliance can be reduced accordingly.

In the cosmetic device described above, the output current to the skin irritant 3 is increased in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface.

The skin care can be effectively performed by the cosmetic device that increases the output current to the skin stimulator 3 in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface. Further, since the output current to the skin stimulator 3 can be automatically increased while the skin abnormality is found, the user's labor and time for switching can be saved.
