Problems to be solved by the invention
In the cosmetic treatment device of patent document 1, RF electrodes for applying cosmetic stimulation are arranged in a grid pattern on the outer surface of the transmission plate. Therefore, the cosmetic treatment can be performed without any trouble on a flat and large-area skin surface such as a cheek or a forehead. However, if all the contact sensors are not in contact with the skin, the RF current is not supplied to the RF electrode. Therefore, a cosmetic treatment cannot be performed on a narrow skin region such as the periphery of the nose and the periphery of the eyes using a part of the RF electrodes, and the entire face skin cannot be subjected to a cosmetic treatment.
The present invention aims to provide a cosmetic device which can attach a warm head to a flat and large-area skin surface such as a cheek or a forehead, and which can attach the warm head to a narrow skin area such as a periphery of a nose or a periphery of an eye, thereby performing a cosmetic treatment on the entire face skin.

A thermal head 2 is provided on the front surface of the main body case 1, and the thermal head 2 includes a wide stimulation head 18 and a narrow stimulation head 19 that apply cosmetic stimulation to the skin surface. A cold and hot head 3 for cooling the skin surface is provided on the rear surface of the main body case 1.
The effects of the invention are as follows.
In the beauty appliance of the present invention, the warm head 2 provided in the main body casing 1 is provided with a wide stimulation head 18 for applying beauty stimulation to a large area of the skin surface and a narrow stimulation head 19 for applying beauty stimulation to a small area of the skin surface. Skin contact bodies 22 and 32 for applying stimulation to the skin surface are provided in the wide area stimulation head 18 and the narrow area stimulation head 19, respectively. According to such a cosmetic device, by using the wide stimulation head 18, it is possible to appropriately perform cosmetic treatment on a flat and large-area skin surface such as a cheek or a forehead, and also possible to appropriately perform cosmetic treatment on a narrow skin portion such as a portion around a nose or a portion around an eye by using the narrow stimulation head 19. Therefore, a beauty treatment appliance capable of performing a beauty treatment on the entire face skin can be provided. Further, since the skin contact bodies 22 and 32 are provided for the respective stimulation heads 18 and 19, the skin can be appropriately heated.
The electrode face of the skin contact 32 of the narrow stimulation head 19 is inclined with respect to the electrode face of the skin contact 22 of the wide stimulation head 18. According to such a cosmetic device, when one of the stimulation heads 18 (or 19) is used, the other stimulation head 19 (or 18) is inclined and accordingly separated from the skin surface, so that the other stimulation head 19 (or 18) does not come into contact with the skin surface, and thus the cosmetic treatment can be appropriately performed by each of the stimulation heads 18 and 19.
The head surface 30 of the narrow stimulation head 19 supporting the skin contact body 32 is inclined relative to the head surface 20 of the wide stimulation head 18 supporting the skin contact body 22. According to such a cosmetic device, the wide stimulation head 18 and the narrow stimulation head 19 can be distinguished from each other according to the difference in inclination in addition to the difference in area of the respective stimulation heads 18 and 19, and in particular, the user can intuitively recognize the part to be treated for beauty using the narrow stimulation head 19. Therefore, it is possible to favorably prevent the use of the respective stimulation heads 18 and 19 by an incorrect use method.
The wide stimulation head 18 and the narrow stimulation head 19 are provided with temperature sensors 27 and 37 for detecting skin temperature, respectively. According to such a beauty treatment apparatus, since the temperature state of the skin contact bodies 22 and 32 in the respective stimulation heads 18 and 19 can be accurately detected, it is possible to surely prevent the skin temperature from increasing more than necessary, and to perform a beauty treatment safely.
Either one of the temperature sensor 27 provided in the wide stimulation head 18 and the temperature sensor 37 provided in the narrow stimulation head 19 also serves as an environmental temperature sensor of an environment in which the cosmetic device is used. According to such a cosmetic device, for example, when cosmetic treatment is performed using the wide-area stimulation head 18, the temperature sensor 37 provided in the narrow-area stimulation head 19 detects the ambient temperature, and the operation state of the wide-area stimulation head 18 can be adjusted according to the season and the indoor temperature. For example, the following control and the like can be performed: in summer when the ambient temperature is high, the drive wave current supplied to the skin contact body 22 is adjusted to be higher than the reference output value, and in winter, the drive current supplied to the skin contact body 22 is adjusted to be lower than the reference output value. In the case of the thermal head 2 configured to provide the PTC heater isothermal heat source inside the skin contact body 22, the drive wave current supplied to the thermal source can be adjusted to correspond to the difference in the environmental temperature.
High-frequency voltage is applied to the skin contact bodies 22, 32, and the skin is heated by the heating action of the high-frequency current flowing through the skin. According to such a cosmetic device, since the skin can be heated from the inside by the heat generation action of the high-frequency current flowing through the skin, the skin can be heated quickly and efficiently, as compared with a case where the skin is heated by the heat conduction action from the skin surface toward the inside of the skin by, for example, pressing the heated thermal head 2 against the skin surface.
The skin contact bodies 22, 32 of the respective stimulation heads 18, 19 are constituted by the first electrodes 23, 33 and the second electrodes 24, 34, and the control unit 48 adjusts the supply state of the high-frequency current to the respective skin contact bodies 22, 32 in accordance with the threshold value of the detection signal of the temperature sensors 27, 37. In addition, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow stimulator head 19 is set to be smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide stimulator head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 of the narrow-area stimulating head 19 is set to be small, the temperature control of the narrow-area stimulating head 19 can be controlled from a stage of a lower temperature than the wide-area stimulating head 18, and the narrow-area stimulating head 19 can be prevented from falling into a high-temperature state.
In the adjacent portion between the wide-area stimulating head 18 and the narrow-area stimulating head 19, the second electrode 24 on the wide-area stimulating head 18 side and the second electrode 34 on the narrow-area stimulating head 19 side are integrally formed to constitute a common electrode 36. According to the thermal head 2, as compared with the case where the second electrodes 24 and 34 are provided independently on the respective stimulation heads 18 and 19, the number of parts can be reduced and the electrode structure can be simplified, and accordingly, the cost of the beauty appliance can be reduced. The height of protrusion of each of the electrodes 23 and 24 from the head surface 20 in the wide-area stimulation head 18 is set to be equal to the height of protrusion of the second electrode 24 constituting the common electrode 36 from the head surface 20, or greater than the height of protrusion of the second electrode 24 constituting the common electrode 36 from the head surface 20. The protruding height of each of the electrodes 33 and 34 in the narrow stimulation head 19 from the head surface 30 is set to be smaller than the protruding height of the second electrode 24 on the wide stimulation head 18 side constituting the common electrode 36 from the head surface 20. According to such a cosmetic device, the plane (plane in contact with the skin) connecting the first electrode 33 of the narrow stimulation head 19 and the second electrode 34 of the common electrode 36 can be made to intersect with the plane (plane in contact with the skin) connecting the first electrode 23 of the wide stimulation head 18 and the second electrode 24 of the common electrode 36. Therefore, for example, when cosmetic treatment is performed using the narrow stimulation head 19, the electrodes 23 and 24 of the wide stimulation head 18 can be favorably prevented from coming into contact with the skin surface.
The head surface 30 of the narrow stimulation head 19 is set to be gradually lower from the adjacent portion of the second electrodes 24, 34 constituting the common electrode 36 over the tip of the narrow stimulation head 19. According to such a cosmetic device, the posture of the warm head 2 in close contact with the skin is greatly different between the case of using the wide stimulation head 18 and the case of using the narrow stimulation head 19, and thus, the electrodes 23 and 24 of the wide stimulation head 18 can be more reliably prevented from coming into contact with the skin surface when the cosmetic treatment is performed using the narrow stimulation head 19.
When the head surface 30 on the narrow stimulation head 19 side is tilted backward with respect to the head surface 20 on the wide stimulation head 18 side, the posture of the cosmetic device when the stimulation heads 18 and 19 are brought into contact with the skin surface is further greatly changed, and when the cosmetic treatment is performed using the narrow stimulation head 19, the electrodes 23 and 24 of the wide stimulation head 18 can be more reliably prevented from coming into contact with the skin surface.
In the adjacent portion between the wide-area stimulating head 18 and the narrow-area stimulating head 19, the second electrode 24 on the wide-area stimulating head 18 side and the second electrode 34 on the narrow-area stimulating head 19 side are integrally formed to constitute a common electrode 36. In addition, a temperature sensor 27 for detecting the skin temperature is provided inside the common electrode 36. According to the beauty appliance, compared with the case that the temperature sensors 27 and 37 are respectively and independently arranged on the stimulating heads 18 and 19, the number of parts is reduced, the electrode structure is simplified, and accordingly, the cost of the beauty appliance can be reduced.
The temperature sensor 27 provided in the common electrode 36 also serves as an environmental temperature sensor of an environment in which the cosmetic device is used. In such a beauty appliance, the control unit 48 can recognize the ambient temperature of the use environment of the user from the temperature detected by the temperature sensor 27 immediately after the power button unit 5 is turned on, and can adjust the drive current supplied to the skin contact bodies 22 and 32 in a state suitable for the ambient temperature.
The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with skin contact sensors for detecting contact between the skin contact bodies 22 and 32 and the skin surface. According to such a beauty appliance, the drive current to be supplied to the skin-contacting bodies 22 and 32 is adjusted according to the presence or absence of the detection signal of the skin contact sensor, or the threshold value of the detection signal of the temperature sensor 27 or 37 is adjusted, so that the drive current to be supplied to the skin-contacting bodies 22 and 32 can be optimized, and unnecessary power consumption can be reduced.
The skin contact body 22 of the broad area stimulation head 18 and/or the skin contact body 32 of the narrow area stimulation head 19 doubles as a skin contact sensor. When the skin contact bodies 22, 32 of the respective stimulation heads 18, 19 are in contact with the skin surface, the control unit 48 adjusts the high-frequency current supplied to the skin contact bodies 22, 32 or adjusts the threshold value of the detection signal of the temperature sensor 27 based on the detection signal output from the skin contact bodies 22, 32. According to such a beauty appliance, the skin-contacting bodies 22, 32 of the respective stimulation heads 18, 19 can be used to detect the contact of the skin-contacting bodies 22, 32 with the skin surface, and the number of parts can be reduced and the structure of the thermal head 2 can be simplified as compared with the case where a skin contact sensor is separately provided, and accordingly, the cost of the beauty appliance can be reduced.
In the adjacent portions of the head surfaces 20, 30 of the respective stimulation heads 18, 19, the second electrode 24 on the wide-area stimulation head 18 side and the second electrode 34 on the narrow-area stimulation head 19 side are formed by bent continuous planes. According to the thermal head 2, as compared with the case where the second electrodes 24 and 34 are provided independently on the respective stimulation heads 18 and 19, the number of parts can be reduced and the electrode structure can be simplified, and the processing cost of the second electrodes 24 and 34 can be reduced, which in turn can reduce the cost of the cosmetic device.
The first electrodes 23, 33 and the second electrodes 24, 34 of the respective stimulation heads 18, 19 are formed integrally, respectively. According to such a beauty appliance, as compared with the case where the electrodes 23, 24, 33, and 34 are formed independently of each other, the number of parts constituting the thermal head 2 can be reduced, and the cost required for manufacturing the beauty appliance can be reduced.
The skin contact body 22 of the broad area stimulation head 18 is configured by a first electrode 23 disposed at the center of the head surface 20 and a plurality of second electrodes 24 disposed around the first electrode 23, and at least one second electrode 24 constitutes a common electrode 36. According to the cosmetic device, since the periphery of the first electrode 23 is surrounded by the plurality of second electrodes 24, the cosmetic treatment can be appropriately performed with the cosmetic liquid held between the first electrode 23 and the second electrodes 24. In addition, when the thermal head 2 is slid along the skin surface to perform the cosmetic treatment, the cosmetic liquid can be prevented from being pushed away by the first electrode 23 and the second electrode 24.
The first electrode 23 of the wide-area stimulation head 18 is formed in a polygonal shape, and a plurality of second electrodes 24 are arranged around the electrode 23 at predetermined intervals. The corner 23a of the first electrode 23 faces the adjacent slit of the second electrode 24. According to such a beauty treatment instrument, when the warm head 2 is slid along the skin surface to perform the beauty treatment, the beauty treatment liquid flowing in from the gap adjacent to the second electrode 24 is branched at the corner portion 23a, and one of the beauty treatment liquid flows along the periphery of the first electrode 23 and flows out to the outside of the skin contact body 22. Therefore, the replacement of the cosmetic liquid between the first electrode 23 and the second electrode 24 is facilitated, and the cosmetic effect of the cosmetic device can be improved.
The corner 23a of the first electrode 23 is located more inward than an imaginary outer contour line H2 connecting the outer edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warm head 2 along the skin surface, the cosmetic liquid to be introduced from the gap adjacent to the second electrode 24 is guided to flow at the corner portion 23a, and can be sent between the first electrode 23 and the second electrode 24. Therefore, the receiving amount of the cosmetic liquid around the second electrode 24 between the first electrode 23 and the second electrode 24 can be increased.
The corner 23a of the first electrode 23 is located more inward than an imaginary outer contour H1 connecting the inner edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warm head 2 along the skin surface, the cosmetic liquid entering from the gap adjacent to the second electrode 24 is guided to flow at the corner portion 23a, and can be held between the first electrode 23 and the second electrode 24. Therefore, as described above, in the case where the corner portion 23a of the first electrode 23 is located further inside than the imaginary outer contour line H2 connecting the outer edges of the second electrode 24, more cosmetic liquid can be received and held between the first electrode 23 and the second electrode 24.
The warm head 2 having the wide stimulation head 18 and the narrow stimulation head 19 is provided on the front surface of the main body housing 1, and the cold head 3 for cooling the skin surface is provided on the rear surface of the main body housing 1. According to such a beauty appliance, it is not necessary to prepare a beauty appliance having a hot and cold head 3 separately from a beauty appliance having a warm and hot head 2, and the warm and hot heads 2 and 3 can be used separately by merely changing the front and rear postures of the hand-held main body casing 1.

Switches 12 are mounted on the front surface of the circuit board 11 in correspondence with the respective buttons 5 to 7, and LEDs 13 are mounted in correspondence with the respective displays 8 and 9.
(Warm head)
The thermal head 2 integrally includes a cylindrical base case 16 fixed to the main body case 1, and a head case 17 formed in a front portion of the base case 16 and having a droplet shape in front view. The wide stimulation head 18 that applies cosmetic stimulation to a large area of the skin surface and the narrow stimulation head 19 that applies cosmetic stimulation to a small area of the skin surface are provided in the warm head 2 and the head case 17. The cosmetic stimulation consists of thermal stimulation and electrical stimulation.
As shown in fig. 1 and 4, the wide stimulation head 18 includes a head surface 20 having an incomplete circular shape, an electrode pad 21 protruding inward of the head surface 20, a skin electrode (skin contact body) 22 disposed on the surface of the electrode pad 21 and heating the skin surface, and the like. The head surface 20 is constituted by a plane orthogonal to the central axis of the base housing 16, and the electrode stage 21 is constituted by a curved surface bulging forward from the head surface 20 by a small margin. The skin electrode 22 is composed of a first electrode 23 of a regular hexagon disposed at the center of the electrode stage 21, and six second electrodes 24 of an isosceles trapezoid disposed around each side of the first electrode 23. The six second electrodes 24 are formed integrally, and the adjacent second electrodes 24 are continuous with each other via a connecting portion (shown by a dotted line) provided inside the broad area stimulating head 18.
Each corner 23a of the first electrode 23 faces an adjacent slit of the second electrode 24. The corner 23a of the first electrode 23 is located inside a hexagonal virtual outer contour H1 connecting the inner edges of the second electrode 24. As described above, when the corner portion 23a faces the adjacent gap of the second electrode 24, the cosmetic liquid applied to the skin of the face can be smoothly introduced into the liquid holding portion 26 from the adjacent gap of the second electrode 24, and the cosmetic liquid can be applied to the skin surface between the first electrode 23 and the second electrode 24 on which the high-frequency current acts while giving the thermal stimulation to the skin surface, thereby improving the cosmetic effect. As described above, the same effect can be exhibited by applying the cosmetic device including only the wide stimulator head 18 without the narrow stimulator head 19 to the cosmetic device including the narrow stimulator head 19 in which the first electrode 23 of the wide stimulator head 18 is formed in a polygonal shape and the plurality of second electrodes 24 are arranged around the first electrode 23 at predetermined intervals, the corner 23a of the first electrode 23 is located inside the virtual outer contour line H2 connecting the outer edges of the second electrodes 24, and the corner 23a of the first electrode 23 is located inside the virtual outer contour line H1 connecting the inner edges of the second electrodes 24.
The first electrode 23 is provided in a state of being protruded from the surface of the electrode stage 21, whereas the second electrode 24 is provided in a state of being embedded in a holder frame 25 protruded from the electrode stage 21, and the surface thereof is exposed so as to be leveled with the holder frame 25. The first electrode 23 and the holder frame 25 are projected from the surface of the electrode base 21, and a cosmetic liquid such as a cosmetic liquid can be held in the liquid holding portion 26 between the first electrode 23 and the holder frame 25. A temperature sensor 27 such as a thermistor for detecting the skin temperature is provided inside the first electrode 23. The first electrode 23 and the second electrode 24 are formed of, for example, a titanium plate material.
The narrow stimulation head 19 includes a semicircular head surface 30 continuous with the head surface 20 of the wide stimulation head 18, an electrode pad 31 protruding inside the head surface 30, a skin electrode (skin contact body) 32 disposed on the surface of the electrode pad 31 and heating the skin surface, and the like. The head face 30 is formed of a curved surface slightly bulging obliquely upward, and the entire head face 30 is inclined rearward with respect to the head face 20 of the broad area stimulation head 18. In fig. 1, the narrow stimulation heads 19 are formed on the upper side of the boundary line b of the both head surfaces 20 and 30. In this embodiment, the head surface 30 of the narrow stimulation head 19 is tilted back at about 45 degrees relative to the head surface 20 of the wide stimulation head 18 (see fig. 4).
The electrode stage 31 is formed of a curved surface that is substantially parallel to the head surface 30 and slightly curved. The skin electrode 32 includes a first electrode 33 having an upwardly projecting semicircular shape disposed on the upper half side of the electrode stage 31 and a second electrode 34 having a downwardly projecting semicircular shape disposed on the lower side of the first electrode 33, and the electrodes 33 and 34 are provided in a state of being embedded in a holder frame 35 formed in a bulged manner on the electrode stage 31, and the surfaces thereof are exposed so as to be flush with the holder frame 35. The second electrode 34 is integrally formed with the second electrode 24 on the upper portion of the broad area stimulation head 18 to constitute a common electrode 36. A temperature sensor 37 such as a thermistor for detecting the skin temperature is provided inside the first electrode 33. The first electrode 33 and the second electrode 34 are formed of, for example, a titanium plate material. The second electrode 24, the first electrode 33, and the second electrode 34 need not be embedded in the holder frames 25 and 35, and may be configured to protrude from the electrode stage 21 in the same manner as the first electrode 23. As described above, the surfaces of the skin-contacting bodies 22 and 32 that contact the skin become electrode surfaces (skin contact surfaces), and the area of the electrode surface of the skin-contacting body 32 is set smaller than the area of the electrode surface of the skin-contacting body 22.
(Cold and hot head)
In fig. 3, the cold/hot head 3 includes a peltier element 40, a cold/hot head 41 disposed on the rear surface of the peltier element 40 and configured to transfer cold/hot to the skin surface, a heat sink 42 disposed on the front surface of the peltier element 40 and configured to release heat, and the like. The thermal head 41 is formed of an aluminum die-cast product, and the heat-conducting surface 43 thereof is exposed outside the mounting window of the rear case 1 b. The heat sink 42 is made of an aluminum die-cast product, and releases the heat of the peltier element 40 through a pair of heat radiating fins. Although not shown, a discharge window for discharging warm heat to the outside of the housing is provided in the opening of the rear housing 1 b. Acceleration sensors 45 for detecting the state of the beauty appliance in use are provided at the upper and lower sides of the inside of the main body casing 1.
(control section)
As shown in fig. 5 and 6, the beauty appliance is provided with a control unit 48 for controlling the operation states of the thermal head 2 and the thermal head 3. When the power button unit 5 is turned on, the warm operation mode is started, and the control unit 48 applies a high-frequency voltage to the skin electrodes 22 of the wide stimulation head 18 and the skin electrodes 32 of the narrow stimulation head 19 via the high-frequency output unit 49, and turns on the mode display unit 8 on the warm operation mode side. When the level switch button unit 7 is turned on, the control unit 48 cyclically switches the high-frequency voltage applied to the skin electrodes 22 and 32 in the order of weak, medium, and strong, and applies the selected high-frequency voltage to the skin electrodes 22 and 32. At the same time, the lighting state of the level display unit 9 is associated with the level switching state.
As described above, in a state where the beauty equipment is ready, for example, when the skin electrode 22 of the wide-area stimulation head 18 is brought into close contact with the facial skin such as the cheek and the forehead to which the lotion or the lotion is applied and is slid along the facial skin, the acceleration sensor 45 detects the movement, and the control unit 48 supplies the high-frequency current between the pair of electrodes 23 and 24. Specifically, a high-frequency voltage of a sine wave having a frequency of 1MHz is applied between the first electrode 23 and the second electrode 24, or between the first electrode 33 and the second electrode 34. This enables the skin to be heated by the high-frequency current flowing through the skin between the pair of electrodes 23 and 24. The cosmetic stimulation in this case is both thermal stimulation and electrical stimulation. The control unit 48 can recognize whether or not the cosmetic device is being used, based on the detection signal output from the acceleration sensor 45. The control unit 48 can recognize whether or not the broad area stimulation head 18 is in close contact with the skin based on the current value detected by the current value detection unit 50 (see fig. 6). On the other hand, in a state where the narrow stimulation head 19 is in close contact with the skin surface, the control unit 48 can recognize whether or not the narrow stimulation head 19 is in close contact with the skin based on the detection signal of the current value detection unit 50. So that the acceleration sensor 45 can be saved. In this case, when the power button unit 5 is turned on, the control unit 48 starts a timer, applies a high-frequency voltage to the skin electrodes 22 and 32 of the wide stimulation head 18 and the narrow stimulation head 19, and turns off the power supply at a timing when a predetermined time has elapsed.
When the detection signal from one of the two acceleration sensors 45 is not output for a certain period of time, the warm head 2 may not move in a state of being in close contact with the face skin, and the control unit 48 may reduce or stop the supply of the high-frequency current to the skin electrodes 22 and 32. Then, the control unit 48 monitors the detection signal output from the current value detection unit 50 as needed, and when the detection signal of the current value detection unit 50 is larger than the threshold value (reference current value), as shown in fig. 7, determines that the skin electrode 22 of the broad area stimulation head 18 of the skin electrodes 22 and 32 is in contact with the skin surface, and increases the output value of the high frequency current (supply power) supplied to the skin electrode 22 to the reference output value or more. When the detection signals are not output from the two acceleration sensors 45, it is determined that the cosmetic device is not in operation, and the supply of the high-frequency current is reduced or stopped. Conversely, when the detection signal of the current value detection unit 50 is smaller than the threshold value, it is determined that the skin electrode 32 of the narrow stimulation head 19 of the skin electrodes 22 and 32 is in contact with the skin surface, and the output value of the high-frequency current (supply power) supplied to the skin electrode 32 is lower than the reference output value. This is because: the area and heat capacity of the skin electrode 32 of the narrow stimulator head 19 are small, and the heat radiation area is small, so that the temperature is likely to rise, and if a high-frequency current equal to that of the skin electrode 22 of the wide stimulator head 18 is supplied to the skin electrode 32, the degree of rise in the skin temperature by the skin electrode 32 is large, and as described below, even if the control unit 48 performs temperature control upon receiving a detection signal of the temperature sensor 37, there is a possibility that the skin may temporarily fall into an overshoot state. As described above, the control unit 48 of the present embodiment is configured to be able to detect which of the wide-area stimulation head 18 and the narrow-area stimulation head 19 is in contact with the skin, based on the value of the current flowing through the skin between the first electrode 23 and the second electrode 24 in the wide-area stimulation head 18 and the value of the current flowing through the skin between the first electrode 33 and the second electrode 34 in the narrow-area stimulation head 19. In addition, when detecting that the narrow stimulation head 19 is in contact with the skin, the control unit 48 supplies the narrow stimulation head 19 with the supply power in a state of being reduced from the supply power to the wide stimulation head 18. On the other hand, when detecting that the wide-area stimulation head 18 is facing the skin, the control unit 48 supplies the wide-area stimulation head 18 with the supply power in a state in which the supply power is increased from the supply power to the narrow-area stimulation head 19. That is, when either one of the wide-area stimulation head 18 and the narrow-area stimulation head 19 is in contact with the skin, the electric power corresponding to the head can be automatically supplied from the high-frequency output unit 49. Therefore, the trouble of switching the supply power by manual operation can be saved. Further, since the switching is not forgotten, unnecessary increase in skin temperature can be reliably prevented. The current value detection unit 50 and the skin electrodes 22 and 32 constitute a skin contact detection unit. In the present embodiment, the skin electrodes 22 and 32 also serve as skin contact sensors, but the skin contact sensors may be configured to be provided with dedicated sensors such as capacitance type contact sensors, independently of the skin electrodes 22 and 32.
In the middle of using the wide-area stimulation head 18 or the narrow-area stimulation head 19, when the detection signal of either one of the temperature sensors 27 and 37 exceeds the threshold value, the control unit 48 reduces the supply state of the high-frequency current (supply power) to the skin electrode 22 or the skin electrode 32, thereby preventing the skin temperature from increasing. If the detection signal is less than or equal to the threshold, the supply state of the high-frequency current is returned to the initial state, and after the detection signal exceeds the threshold again, the supply state of the high-frequency current is lowered. By repeating the above operation, the skin temperature becomes constant. In the present embodiment, the threshold value (operating temperature) of the temperature sensor 27 is set to 45 ℃, and the threshold value (operating temperature) of the temperature sensor 37 is set to 43 ℃. That is, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow stimulator head 19 is set to be smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide stimulator head 18. In this way, the thresholds of the detection signals of the temperature sensors 27 and 37 in the respective stimulation heads 18 and 19 are made different in order to avoid the following: the area and heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 are small, and the heat radiation area is small, so that the temperature is likely to rise, and if a high-frequency current equal to that of the skin electrode 22 of the wide-area stimulation head 18 is supplied to the skin electrode 32, the degree of rise in the skin temperature by the skin electrode 32 is large, so that the temperature of the skin in contact with the skin electrode 32 may become high. That is, when a high-frequency current is supplied to the skin electrode 32 of the narrow stimulation head 19, the threshold value of the temperature sensor 37 is set to be low, so that even if overshoot occurs, the skin temperature can be prevented from increasing.
As described above, the temperature sensors 27 and 37 may have at least either a structure for preventing the skin temperature from increasing by making the threshold values different from each other, or a structure for making the supply states of the high-frequency current to the skin electrodes 22 of the wide-area stimulation head 18 and the skin electrodes 32 of the narrow-area stimulation head 19 different from each other as described above. When the temperature rise of the narrow-area stimulating head 19 is suppressed by changing the supply state of the high-frequency current, the balance between heating and heat dissipation can be adjusted by significantly suppressing the amount of application of the high-frequency voltage or the amount of supply of the high-frequency current, so that the skin temperature does not rise more than necessary in the case of sensorless temperature control. The control unit 48 can recognize the ambient temperature of the use environment of the user by the temperature sensor 37 of the unused narrow-area stimulation head 19, for example, and can adjust the supply state of the drive current to the skin electrode 22 used in a state corresponding to the ambient temperature. For example, in summer, as indicated by the upward open arrows in fig. 7, the drive current supplied to the skin electrodes 22 is adjusted to be higher than the reference output value, and in winter, as indicated by the downward open arrows in fig. 7, the drive current supplied to the skin electrodes 22 is adjusted to be lower than the reference output value. In the present embodiment, the control unit 48 recognizes the ambient temperature of the use environment of the user by the temperature sensor 37 of the unused narrow stimulation head 19, but the ambient temperature can be recognized by the temperature sensor 27 of the skin electrode 22 on the use side. In this case, the ambient temperature is detected and recognized immediately after the power button unit 5 is turned on, the supply state of the high-frequency current is adjusted in advance, and the temperature sensor 27 is used as a temperature sensor for the original temperature control when the skin electrode 22 is pressed against the skin surface.
After a predetermined time has elapsed, the control unit 48 drives the sound emitter, not shown, and notifies the user that the operating time corresponding to the set operating mode has elapsed. Similarly, by bringing the skin electrode 32 of the narrow stimulation head 19 into close contact with the periphery of the nose, the periphery of the eye, or the like, or sliding it along the face skin, the skin can be heated by the high-frequency current flowing through the skin between the pair of electrodes 33, 34, and the entire face skin can be beautifully treated.
Since the area of the skin electrode 32 of the narrow stimulation head 19 is much smaller than the area of the skin electrode 22 of the wide stimulation head 18, and the narrow stimulation head 19 is tilted backward greatly with respect to the wide stimulation head 18, the skin electrode 32 of the narrow stimulation head 19 can be smoothly and appropriately performed for the cosmetic treatment of a narrow part. Further, since the area of the skin electrode 32 of the narrow stimulation head 19 is small, if the same high-frequency current as that for bringing the skin electrode 22 of the wide stimulation head 18 into close contact with the skin surface is supplied to the skin electrode 32, the power converted into heat between the electrodes 33 and 34 becomes large, the degree of increase in the skin temperature per unit time becomes large, and the skin may be unnecessarily heated. To eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow stimulation head 19 is in close contact with the skin based on the current value of the current value detection unit 50, and reduces the high-frequency current supplied to the skin electrode 32 to be lower than the high-frequency current supplied to the skin electrode 22. In addition, the threshold value of the temperature sensor 37 of the narrow stimulation head 19 is set to be lower than the threshold value of the temperature sensor 27 of the wide stimulation head 18, thereby preventing the skin from being unnecessarily heated.
When the cosmetic treatment by the wide-area stimulation head 18 and the narrow-area stimulation head 19 is completed, the mode button portion 6 is turned on to switch the operation mode from the warm operation mode to the cold operation mode, and the driving current is supplied to the peltier element 40 to turn on the mode display lamp 8 on the cold operation mode side. After a predetermined time has elapsed and the temperature of the heat conduction surface 43 of the thermal head 41 has decreased to the use temperature, the heat conduction surface 43 is cooled by being brought into close contact with the skin of the face. When a predetermined time has elapsed since the supply of the drive current to the peltier element 40, the supply of the drive current is stopped, the cooling process of the face skin by the thermal head 41 is ended, and the power button unit 5 is pressed to turn off all the operation modes.
(example 2)
Fig. 8 shows a beauty treatment apparatus according to embodiment 2 of the present invention. The beauty appliance of embodiment 2 is different from the beauty appliance of embodiment 1 in that a temperature sensor 27 is disposed inside the common electrode 36. In this way, if the temperature sensor 27 is disposed inside the common electrode 36, the skin temperature can be detected by one temperature sensor 27 in both the case of using the wide-area stimulation head 18 and the case of using the narrow-area stimulation head 19, and the temperature sensor 37 can be omitted, which can reduce the manufacturing cost of the cosmetic device accordingly. Further, since the control unit 48 can recognize the ambient temperature of the use environment of the user based on the temperature detected by the temperature sensor 27 immediately after the power button unit 5 is turned on, the drive current supplied to the skin electrode 22 can be adjusted to suit the ambient temperature, as in the cosmetic device of embodiment 1. In embodiment 1, the threshold value of the detection signal of the temperature sensor 27 and the threshold value of the detection signal of the temperature sensor 37 are independently set, but in the present embodiment, the threshold values of the detection signals may be independently set similarly. More specifically, based on the detection signal of the skin contact detection unit including the current detection unit 50 and the skin electrodes 22 and 32, the control unit 48 sets the threshold value of the detection signal of the temperature sensor 27 to, for example, 45 ℃ when the skin electrode 22 of the wide stimulation head 18 is in contact with the skin surface, and sets the threshold value of the detection signal of the temperature sensor 27 to, for example, 43 ℃ when the skin electrode 32 of the narrow stimulation head 19 is in contact with the skin surface. That is, the threshold value of the detection signal of the temperature sensor 27 when the narrow stimulator head 19 is used is set to be smaller than that when the wide stimulator head 18 is used. This can prevent an unnecessary increase in the temperature of the skin surface, as in the case of the beauty appliance of embodiment 1. Further, the control unit 48 can recognize the ambient temperature of the use environment of the user based on the temperature detected by the temperature sensor 27 immediately after the power button 5 is turned on, and can adjust the drive current supplied to the skin electrodes 22 and 32 in accordance with the ambient temperature, as in the cosmetic device of embodiment 1.

Fig. 9 shows a beauty treatment apparatus according to embodiment 3 of the present invention. The cosmetic device according to embodiment 3 is different from the cosmetic device according to embodiment 1 in that the head surface 30 of the narrow stimulation head 19 is formed of a curved surface continuous with the head surface 20 of the wide stimulation head 18, and the entire head surface 30 is slightly inclined backward. In this way, the head surface 30 of the narrow stimulation head 19 can also be slightly tilted backward without being greatly tilted backward.
(example 4)
Fig. 10 to 12 show a beauty appliance according to embodiment 4 of the present invention. In the cosmetic device according to embodiment 4, the wide stimulation head 18 and the narrow stimulation head 19 are provided on one head surface 20. Specifically, the triangular first electrode 23 is provided at the center of the head surface 20, and the three second electrodes 24 constituting the skin electrodes 22 of the wide-area stimulation head 18 and the three second electrodes 34 constituting the skin electrodes 32 of the narrow-area stimulation head 19 are alternately arranged around the triangular first electrode 23, so that the second electrodes 24 can be shared. The second electrode 24 of the wide-area stimulation head 18 is arranged parallel to the side of the first electrode 23, and the second electrode 34 of the narrow-area stimulation head 19 is arranged facing the corner 23a of the first electrode 23.
As shown in fig. 12, among the electrodes 23, 24, and 34, the height h1 at which the first electrode 23 protrudes from the head surface 20 is the highest, and the height h2 at which the second electrode 24 protrudes from the head surface 20 and the height h3 at which the second electrode 34 protrudes from the head surface 20 are set to be lower in order. Further, the skin contact surface of the first electrode 23 is inclined to a different degree by the difference between the projection height h2 of the second electrode 24 and the projection height h3 of the second electrode 34, and the skin contact surface of the first electrode 23 is inclined downward toward the electrodes 24 and 34, whereby the first electrode 23 on the wide stimulation head 18 side is prevented from contacting the skin, particularly when the narrow stimulation head 19 having a small electrode area is used.
(example 5)
Fig. 13 and 14 show a beauty treatment instrument according to embodiment 5 of the present invention. In the cosmetic device according to embodiment 5, the head surface 30 of the narrow stimulation head 19 and the head surface 20 of the wide stimulation head 18 are formed in a square shape with rounded four corners, and the head surface 30 of the narrow stimulation head 19 is inclined backward with respect to the head surface 20 of the wide stimulation head 18, as in the cosmetic device according to embodiment 1. The wide-area stimulation head 18 is provided with a square first electrode 23 and a second electrode 24 parallel to the left and right sides and the lower side of the first electrode 23. The narrow stimulation head 19 is provided with a first electrode 33 and a second electrode 34 that are laterally long. The first electrode 23 of the wide stimulation head 18 is formed integrally with the first electrode 33 of the narrow stimulation head 19, and a connection portion (see a broken line) connecting the electrodes 23 and 33 is disposed inside the thermal head 2 in a hidden state. Similarly, the second electrodes 24 of the wide-area stimulation head 18 and the second electrodes 34 of the narrow-area stimulation head 19 are integrally formed, and a connection portion (see a broken line) connecting the adjacent second electrodes 24 and a connection portion (see a broken line) connecting the second electrodes 24 and the second electrodes 34 are disposed in the thermal head 2 in a hidden state. Temperature sensors 27 and 37 are disposed inside the first electrodes 23 and 33.
(example 6)
Fig. 15 shows a beauty treatment instrument according to embodiment 6 of the present invention. In the cosmetic device according to embodiment 6, the head surface 30 of the narrow stimulation head 19 and the head surface 20 of the wide stimulation head 18 are formed in an oblong shape that is long in the vertical direction, and the head surface 30 of the narrow stimulation head 19 is inclined backward with respect to the head surface 20 of the wide stimulation head 18, as in the cosmetic device according to embodiment 1. The first electrodes 23 of the wide-area stimulating head 18 and the first electrodes 33 of the narrow-area stimulating head 19 are formed in an oval shape that is vertically long and integrally exposed from the head surfaces 20 and 30. The second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 of the narrow-area stimulation head 19 are integrally exposed from the head surfaces 20 and 30, and are formed in an elongated circular ring shape that is long in the vertical direction. A temperature sensor 27 is disposed inside the bent portions of the first electrodes 23 and 33. In the present embodiment, since the first electrode 23 of the wide-area stimulator head 18 and the first electrode 33 of the narrow-area stimulator head 19 are integrally formed, the number of parts can be reduced and the electrode structure can be simplified as compared with the case where the electrodes 23 and 33 are provided separately, and accordingly, the cost of the beauty appliance can be reduced. Further, since the second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 of the narrow-area stimulation head 19 are integrally formed, the number of parts can be reduced and the electrode structure can be simplified as compared with a case where the electrodes 24 and 34 are provided independently, and accordingly, the cost of the cosmetic device can be reduced.
In example 6, the same control as in example 1 was also performed. That is, the control unit 48 monitors the detection signal output from the current value detection unit 50 as needed, and when the detection signal of the current value detection unit 50 is larger than the threshold value (reference current value), as shown in fig. 7, determines that the skin electrode 22 of the broad area stimulation head 18 of the skin electrodes 22 and 32 is in contact with the skin surface, and increases the output value of the high frequency current (supply power) supplied to the skin electrode 22 to the reference output value or more. Conversely, when the detection signal of the current value detection unit 50 is smaller than the threshold value, it is determined that the skin electrode 32 of the narrow stimulation head 19 of the skin electrodes 22 and 32 is in contact with the skin surface, and the output value of the high-frequency current (supply power) supplied to the skin electrode 32 is lower than the reference output value. Since the area of the skin electrode 32 of the narrow stimulation head 19 is small, if the same high-frequency current as that used when the skin electrode 22 of the wide stimulation head 18 is brought into close contact with the skin surface is supplied to the skin electrode 32, the power converted into heat between the electrodes 33 and 34 may increase, and the skin may be unnecessarily heated. To eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow stimulation head 19 is in close contact with the skin based on the current value of the current value detection unit 50, and reduces the high-frequency current supplied to the skin electrode 32 to be lower than the high-frequency current supplied to the skin electrode 22. In example 1, since the first electrodes 23 and 33 are independent, the area and the heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 are greatly different from those of the skin electrode 22 of the wide-area stimulation head 18. Therefore, the skin electrode 32 of the narrow stimulation head 19 having a small heat radiation area tends to increase in temperature. However, in the case of this embodiment, since the first electrodes 23 and 33 and the second electrodes 24 and 34 are integrally connected, the temperature rise of the skin electrode 32 of the narrow stimulation head 19 is not as high as that of embodiment 1.
(example 7)
Fig. 16 and 17 show a beauty treatment instrument according to embodiment 7 of the present invention. In the beauty appliance of embodiment 7, the skin contact body 22 of the wide stimulation head 18 and the skin contact body 32 of the narrow stimulation head 19 are configured in a droplet-like continuous state in the head case 17, the PTC heaters 53 and 54 serving as the thermal heat sources are disposed inside the skin contact bodies 22 and 32, and the temperature sensors 27 and 37 are disposed adjacent thereto. Although not shown, a skin contact sensor is provided in each of the stimulation heads 18 and 19, and a thermal stimulation can be applied to the skin surface by driving the PTC heater 53 (or 54) on the side from which the detection signal of the skin contact sensor is output. In the present embodiment, the skin contact bodies 22 and 32 are formed by the housing surfaces made of a plastic material of the wide-area stimulating head 18 and the narrow-area stimulating head 19 without the skin electrodes 22 and 23 made of metal. In this way, the skin contact members 22 and 32 are not limited to being made of metal, and may be made of plastic material, rubber, or the like. The beauty appliance of the present invention may be a beauty appliance of a type in which the skin contact members 22 and 32 are heated by the PTC heaters 53 and 54 as described above, and the beauty stimulus in this case may be only a thermal stimulus. Thus, there are cases where the cosmetic stimulus is only a thermal stimulus.

Fig. 18 shows a beauty treatment apparatus according to embodiment 8 of the present invention. In the cosmetic device according to embodiment 8, the head surfaces 20 and 30 are formed by vertical flat surfaces perpendicular to the central axis of the base housing 16, and the narrow stimulation head 19 having a small area is provided on the upper portion thereof, and the wide stimulation head 18 is the remaining portion. Nichrome wire heaters 55 and 56 that heat the skin contact bodies 22 and 32 are disposed inside the wide zone stimulation head 18 and the narrow zone stimulation head 19, respectively. The skin contact body 22 of the wide stimulation head 18 and the skin contact body 22 of the narrow stimulation head 19 are on the same plane, but the outer shape and the area thereof are greatly different. In the cosmetic device according to embodiment 1, the head surfaces 20 and 30 can be configured by flat surfaces, as in the cosmetic device according to the present embodiment. The beauty appliance of embodiment 8 can apply thermal stimulation (cosmetic stimulation) to the skin surface using the skin contact bodies 22 and 32 heated by the nichrome heaters 55 and 56.

In this way, the wide stimulation head 18 and the narrow stimulation head 19 can be independently provided at different positions of the main body housing 1.

Fig. 20 shows a beauty treatment apparatus according to an embodiment 10 of the present invention. In the cosmetic device according to embodiment 10, the changeover switch 57 is provided between the high-frequency output unit 49 and the first electrodes 23 and 33, and the current check unit 58 for detecting the supply of the drive current to the respective electrodes 23 and 24 is provided between the first electrode 23 and the second electrode 24 of the skin electrode 22. In this cosmetic device, although the drive current is supplied between the electrodes 23 and 24 of the wide-area stimulation head 18, when the detection signal is not output from the current confirmation unit 58 or the detection signal value is equal to or less than the threshold value, the control unit 48 determines that the cosmetic device is not in use, and switches the changeover switch 57 to supply the drive current to the skin electrode 34 on the narrow-area stimulation head 19 side.
(example 11)
Fig. 21 shows a beauty treatment apparatus according to embodiment 11 of the present invention.

According to this cosmetic device, the user operates the electrode selection switch 59 to switch, and the control unit 48 operates the switch 57 to switch, thereby operating the skin electrode 22 (or the skin electrode 32) on the side designated by the user.
(example 12)
Fig. 22 shows a beauty treatment instrument according to embodiment 12 of the present invention. In the cosmetic device according to example 12, the first electrode 23 of the wide stimulation head 18 and the first electrode 33 on the narrow stimulation head 19 side are integrally formed, the second electrode 24 of the wide stimulation head 18 and the second electrode 34 on the narrow stimulation head 19 side are integrally formed, and the former electrodes 23 and 33 and the latter electrodes 24 and 34 are disposed on the head surfaces 20 and 30 in a state of being adjacent to each other in the left-right direction. The surface area of the former electrodes 23, 33 is set larger than the surface area of the latter electrodes 24, 34, the first electrode 23 and the second electrode 24 constitute the skin electrode 22 of the wide-area stimulation head 18, and the first electrode 33 and the second electrode 34 constitute the skin electrode 32 of the narrow-area stimulation head 19. The imaginary outer contour lines surrounding the periphery of each skin electrode 22, 32 are oval in shape. The surface area of each of the electrodes 23, 24, 33, and 34 is the area of the portion in contact with the skin surface, excluding the area of the peripheral side surface bulging from the head surfaces 20 and 30. The temperature sensors 27 and 37 are disposed inside the second electrodes 24 and 34. As shown in fig. 22, the skin electrode 32 on the narrow stimulation head 19 side is tilted backward with respect to the skin electrode 22 on the wide stimulation head 18 side. As described above, the basic structure of the cosmetic device of embodiment 12 other than the electrode shape and arrangement is the same as that of the cosmetic device of embodiment 1.
In the cosmetic device according to example 12, a high-frequency current is supplied between the first electrode 23 of the broad area stimulation head 18 and the second electrode 24 of the broad area stimulation head 18, and the skin surface is heated from the inside. Similarly, a high-frequency current is supplied between the first electrode 33 of the narrow stimulation head 19 and the second electrode 34 of the narrow stimulation head 19, thereby heating the skin surface from the inside. Since the first electrode 23 of the wide stimulation head 18 and the first electrode 33 of the narrow stimulation head 19 are formed by the continuous plane that is bent, the cross section of the electrode surface (skin contact surface) of the first electrodes 23, 33 of the respective stimulation heads 18, 19 has a shape of "く". Since the second electrode 24 of the wide stimulation head 18 and the second electrode 34 of the narrow stimulation head 19 are formed by the continuous plane that is bent, the cross section of the electrode surface (skin contact surface) of the second electrodes 24, 34 of the stimulation heads 18, 19 has a shape of "く". The electrode surfaces of the first electrodes 23 and 33 and the second electrodes 24 and 34 need not be flat surfaces, but may be formed by curved surfaces protruding outward. The first electrode 23 and the second electrode 24 of the wide stimulation head 18 may be formed by flat surfaces, and the first electrode 33 and the second electrode 34 of the narrow stimulation head 19 may be formed by curved surfaces that protrude outward. The first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be formed by curved surfaces that protrude outward, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be formed by curved surfaces having a curvature larger than the curvature of the curved surfaces of the electrodes 23 and 24. According to the cosmetic device in which at least the first electrode 33 and the second electrode 34 of the narrow stimulation head 19 are formed by the outwardly protruding curved surfaces, when cosmetic treatment is performed by the narrow stimulation head 19, cosmetic treatment of a skin portion having a concave portion such as the periphery of the nose can be appropriately performed. Further, at least one side of the first electrode 33 and the second electrode 34 of the narrow stimulation head 19 is formed by an outwardly protruding curved surface. Thus, the skin part with the concave part can be further accurately treated. In the present embodiment, the skin electrode 22 and the skin electrode 32 are formed by providing one bent portion in the first electrodes 23, 33 and the second electrodes 24, 34, but two bent portions can be provided to constitute another skin electrode having a smaller surface area. In the present embodiment, as shown in fig. 22, the positions of the left and right bent portions are the same, but may be slightly shifted from the upper and lower sides. The outwardly projecting curved surfaces of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be formed of composite arcs having different curvatures on the way, and similarly, the outwardly projecting curved surfaces of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be formed of composite arcs having different curvatures on the way. In particular, when the curvature of the bending portion is set to be small and the curvature is set to be larger than the curvature of the bending portion from the halfway point away from the bending portion to the end portion of the outwardly-projecting curved surfaces of the first electrode 33 and the second electrode 34 of the narrow stimulation head 19, it is possible to accurately treat the skin portion having a depression. The first electrode 33 and the second electrode 34 of the narrow stimulation head 19 may be configured such that the surface on the bent portion side is formed as an inwardly concave curved surface, and the outwardly convex curved surface is continuously connected to the inwardly concave curved surface from a point in the middle away from the bent portion. Accordingly, thermal stimulation can be performed on the skin site at a point. The surfaces of the first electrode 23 and the second electrode 24 of the corresponding wide-area stimulation head 18 may be flat surfaces or curved surfaces that protrude outward. According to such a beauty treatment instrument, when a beauty treatment is performed by the narrow stimulation head 19, the beauty treatment can be appropriately performed on a skin portion having a concave portion such as the periphery of the nose.
In example 12, the same control as in example 1 was also performed. That is, the control unit 48 monitors the detection signal output from the current value detection unit 50 as needed, and when the detection signal of the current value detection unit 50 is larger than the threshold value (reference current value), as shown in fig. 7, determines that the electrode surface (skin contact surface) of the skin electrode 22 of the broad area stimulation head 18 of the skin electrodes 22 and 32 is in contact with the skin surface, and increases the output value of the high frequency current (supply power) supplied to the skin electrode 22 to the reference output value or more. On the other hand, when the detection signal of the current value detection unit 50 is smaller than the threshold value, it is determined that the electrode surface (skin contact surface) of the skin electrode 32 of the narrow-area stimulation head 19 of the skin electrodes 22 and 32 is in contact with the skin surface, and the output value of the high-frequency current (supply power) supplied to the skin electrode 32 is lower than the reference output value. This is because: since the area of the skin electrode 32 of the narrow stimulation head 19 is small, if the same high-frequency current as that used when the skin electrode 22 of the wide stimulation head 18 is brought into close contact with the skin surface is supplied to the skin electrode 32, the power converted into heat between the electrodes 33 and 34 may increase, and the skin may be unnecessarily heated. To eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow stimulation head 19 is in close contact with the skin based on the current value of the current value detection unit 50, and reduces the high-frequency current supplied to the skin electrode 32 to be lower than the high-frequency current supplied to the skin electrode 22. In example 1, since the first electrodes 23 and 33 are independent, the area and the heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 are greatly different from those of the skin electrode 22 of the wide-area stimulation head 18. Therefore, the skin electrode 32 of the narrow stimulation head 19 having a small heat radiation area tends to increase in temperature. However, in the case of the present embodiment, the first electrodes 23 and 33 and the second electrodes 24 and 34 are integrally connected, and the temperature rise of the skin electrode 32 of the narrow stimulation head 19 is not as high as that of embodiment 1.
In example 12, the threshold value (operating temperature) of the temperature sensor 27 was set to 45 ℃ and the threshold value (operating temperature) of the temperature sensor 37 was set to 43 ℃ as in example 1. That is, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow stimulator head 19 is set to be smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide stimulator head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set to be small, it is possible to prevent the temperature of the skin in contact with the skin electrode 32 from increasing when the high-frequency current is supplied to the skin electrode 32 of the narrow-area stimulation head 19.
The beauty appliance of example 12 can be implemented as follows.
The first electrode 23 and the second electrode 24 constituting the skin contact body 22 are provided on the wide-area stimulation head 18, the first electrode 33 and the second electrode 34 constituting the skin contact body 32 are provided on the narrow-area stimulation head 19, the first electrode 23 and the first electrode 33 of the narrow-area stimulation head 19 of the wide-area stimulation head 18, and the second electrode 24 and the second electrode 34 of the narrow-area stimulation head 19 of the wide-area stimulation head 18 are integrally formed and formed in a long shaft shape, respectively, the first electrodes 23 and 33 are arranged side by side with a predetermined interval from the second electrodes 24 and 34, and the total value of the surface areas of the first electrode 23 and the second electrode 24 constituting the skin contact body 22 of the wide-area stimulation head 18 is set to be larger than the total value of the surface areas of the first electrode 33 and the second electrode 34 constituting the skin contact body 32 of the narrow-area stimulation head 19.
According to the cosmetic device of example 12, by using the broad area stimulation head 18, it is possible to appropriately perform the cosmetic treatment of the flat and large-area skin surface such as the cheek and the forehead, and also possible to appropriately perform the cosmetic treatment of the narrow skin portion such as the periphery of the nose and the periphery of the eye by using the narrow area stimulation head 19.
In the cosmetic device according to embodiment 12, the first electrode 23 of the wide stimulation head 18 and the first electrode 33 of the narrow stimulation head 19 are formed by bending continuous planes. Also, the second electrodes 24 of the wide-area stimulation head 18 and the second electrodes 34 of the narrow-area stimulation head 19 are formed by bent continuous planes. According to such a thermal head, as compared with a case where the first electrodes 23 and 33 and the second electrodes 24 and 34 are provided independently on the respective stimulation heads 18 and 19, the number of parts can be reduced and the electrode structure can be simplified, and accordingly, the cost of the cosmetic device can be reduced. Further, since the skin contact surface of the skin electrode 32 of the narrow stimulation head 19 is inclined with respect to the skin contact surface of the skin electrode 22 of the wide stimulation head 18, when one stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) can be prevented from contacting the skin surface, and the respective stimulation heads 18 and 19 can be used appropriately for cosmetic treatment.
In the cosmetic device according to example 12, the temperature sensor 27 is provided inside at least one of the first electrode 23 and the second electrode 24 of the wide stimulation head 18, and the temperature sensor 37 is provided inside at least one of the first electrode 33 and the second electrode 34 of the narrow stimulation head 19. In addition, the threshold of the temperature sensor 37 provided in the narrow stimulation head 19 is set to be smaller than the threshold of the temperature sensor 27 provided in the wide stimulation head 18. According to such a thermal head, when a high-frequency current is supplied to the skin electrode 32 of the narrow-area stimulation head 19, the threshold value of the temperature sensor 37 is set to be low, so that it is possible to prevent the temperature of the skin that is in contact with the skin electrode 32 from increasing.
When the skin electrode 32 of the narrow stimulation head 19 is in close contact with the skin, the high-frequency current supplied to the skin electrode 32 is set to be lower than the high-frequency current supplied to the skin electrode 22. According to such a thermal head, since the area of the skin electrode 32 of the narrow stimulation head 19 is small, if the same high-frequency current as that when the skin electrode 22 of the wide stimulation head 18 is brought into close contact with the skin surface is supplied to the skin electrode 32, the electric power converted into heat between the electrodes 33 and 34 may become large, and the skin may be unnecessarily heated.
(example 13)
Fig. 23 shows a beauty treatment apparatus according to embodiment 13 of the present invention. In the beauty appliance of embodiment 12, the wide stimulation head 18 is provided at a position near the upper portion of the main body casing 1, and the narrow stimulation head 19 is provided at the upper end of the main body casing 1, and in addition, the first electrode 23 and the second electrode 24 of the wide stimulation head 18, and the first electrode 33 and the second electrode 34 of the narrow stimulation head 19 are each constituted by a rotatable roller. Specifically, the first electrodes 23 and the second electrodes 24 of the wide-area stimulation head 18 are alternately arranged two by two, and three insulating rollers 61 are arranged between the electrodes 23 and 24, and the three insulating rollers 61 are rotatably supported by a roller shaft 62 fixed to the main body housing 1. Similarly, the first electrode 33, the insulating roller 63, and the second electrode 34 of the narrow stimulation head 19 are arranged in this order, and the first electrode 33, the insulating roller 63, and the second electrode 34 are rotatably supported by a roller shaft 64 fixed to the main body housing 1. The width and diameter of the first electrode 23 and the second electrode 24 on the skin electrode 22 side are set to be the same as those of the first electrode 33 and the second electrode 34 on the skin electrode 32 side, so that the electrode members can be shared, and the skin electrode 22 is configured by two first electrodes 23 and two second electrodes 24, and the contact area of the skin electrode 22 with the skin is made larger than the contact area of the skin electrode 32 with the skin. In this way, the contact areas of the skin electrodes 22 and 32 with the skin can be made different in size in the following manner. The first electrode 23 and the second electrode 24 on the skin electrode 22 side and the first electrode 33 and the second electrode 34 on the skin electrode 32 side have the same width dimension, but the first electrode 23 and the second electrode 24 on the skin electrode 22 side are set to have a larger diameter than the first electrode 33 and the second electrode 34 on the skin electrode 32 side, and the skin electrode 22 and the skin electrode 32 have different contact areas with the skin. Further, the diameters of the electrodes 23, 24, 33, and 34 may be the same, and the widths of the first electrode 23 and the second electrode 24 on the skin electrode 22 side may be set larger than the widths of the first electrode 33 and the second electrode 34 on the skin electrode 32 side, so that the contact areas of the skin electrodes 22 and 32 with the skin may be different. The electrodes 23, 24, 33, and 34 may have a polygonal cross-sectional shape. The cross-sectional shape of each of the electrodes 23, 24, 33, and 34 can be circular as it is, and a plurality of convex portions or concave portions can be uniformly provided on the peripheral surface. This can be expected to have a skin-irritating effect.
In the present embodiment, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow stimulation head 19 are configured to rotate integrally, but as a modification, the three may be configured to rotate independently. This enables the narrow stimulation head 19 to smoothly change its direction when moved on the skin surface. In addition, the two first electrodes 23, the two second electrodes 24, and the three insulating rollers 61 in the wide-area stimulation head 18 are also configured to rotate integrally, but the three may be configured to rotate independently. However, in consideration of quality and cost, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow stimulation head 19 are integrally rotatable, while the two first electrodes 23, the two second electrodes 24, and the three insulating rollers 61 in the wide stimulation head 18 are integrally rotatable, and the left first electrode 23, the left second electrode 24, and the insulating roller 61 are integrally rotatable, and the right first electrode 23, the right second electrode 24, and the insulating roller 61 are integrally rotatable, so that the electrodes can be independently rotated in the left-right direction. The center insulating roller 61 may be configured to be rotatable integrally with either of the left and right units, or may be configured to be rotatable independently.
In the present embodiment, the narrow stimulation head 19 is fixed, but as a modification, the narrow stimulation head 19 is made to be vertically extendable and retractable with respect to the main body housing 1. In this case, the first electrode 33, the insulating roller 63, and the second electrode 34 are extended and contracted with respect to the main body housing 1 together with the roller shaft 62. A pitch structure (convex portion) is provided in a portion of the roller shaft 62 located inside the main body casing 1, and positioning can be performed at three positions, i.e., a low position, an intermediate position, and a high position, by engagement with the corresponding pitch structure (three concave portions) inside the main body casing 1. By this telescopic structure, the narrow stimulation head 19 can be separated from the wide stimulation head 18, and the wide stimulation head 18 does not interfere with the use of the narrow stimulation head 19, thereby improving the convenience of use. The narrow stimulation head 19 can be completely stored in the main body housing 1. In this case, the pitch is four. This structure can be used to protect the narrow stimulation head 19. The wide stimulation head 18 is also fixed in the present embodiment, but may be made extensible and contractible in the same manner as the narrow stimulation head 19 described above. The expansion and contraction direction in this case is the front-rear direction.
In the present embodiment, the narrow stimulation head 19 is fixed, but as a modification, the narrow stimulation head 19 may be elastically biased in the vertical direction toward the main body housing 1. In this case, the first electrode 33, the insulating roller 63, the second electrode 34, and the roller shaft 62 are elastically biased toward the main body housing 1. Specifically, two coil springs (springs) are provided inside the main body housing 1, and the springs are inserted into the left and right end portions of the roller shaft 62, and are pressed against two contact pieces fixed to the left and right end portions of the roller shaft 62, thereby elastically biasing the narrow stimulation head 19 upward. The two contact pieces come into contact with the inner wall around the opening of the main body housing 1 of the loose fitting roller shaft 62 to regulate upward movement. This restricts upward movement of the entire narrow stimulation head 19. When the narrow stimulation head 19 is pressed against the skin, the narrow stimulation head 19 sinks relative to the main body housing 1 by the pressing force, and can follow the unevenness of the skin, and the load applied to the skin can be reduced. The wide stimulation head 18 is also fixed in the present embodiment, but may be configured to be elastically biased in the same manner as the narrow stimulation head 19 described above. The direction of the elastic urging force in this case is the front-rear direction, not the up-down direction. In the above configuration, a vibrator having a motor and an eccentric cam attached to a motor shaft thereof may be provided inside the narrow field stimulation head 19 and/or the wide field stimulation head 18. Thus, when the vibrator is operated in thermal stimulation, the narrow stimulation head 19 and/or the wide stimulation head 18 can vibrate in a direction in which they are elastically biased, and stimulation due to vibration of a small amplitude can be applied to the skin.
In the present embodiment, the diameters of the two first electrodes 23 and the two second electrodes 24 are the same in the wide-area stimulation head 18, but for example, the diameters of the left-end first electrode 23 and the right-end second electrode 24 are kept unchanged, and the diameters of the inner (center-near) second electrode 24 and first electrode 23 can be set to a size one turn larger than the diameters of the left-end first electrode 23 and right-end second electrode 24. This makes it easy to bring all the electrodes into contact with the skin surface (e.g., submandibular) of the recessed portion, and thus thermal stimulation can be appropriately applied to the skin.
In the present embodiment, the narrow stimulation head 19 and the wide stimulation head 18 are driven rotation structures in which the electrodes 23, 24, 33, and 34 are formed of rollers and are rotated by being pressed against the skin and moved, but may be actively rotated by providing power such as a motor.
In the present embodiment, the narrow stimulation head 19 is provided on the upper surface wall of the main body housing 1, and the wide stimulation head 18 is provided on the front surface wall of the main body housing 1, but the narrow stimulation head 19 may be provided on the rear surface wall of the main body housing 1.
For example, a rectangular housing is rotatably attached to the roller shaft 64, and the narrow stimulation head 19 is rotatably provided on one side of the housing on the upper side, and the wide stimulation head 18 is rotatably provided on the other side of the housing on the opposite side. The portion of the frame attached to the roller shaft 64 is the center portion of the left and right sides of the frame. Thus, when the housing is rotated, the narrow stimulation head 19 or the wide stimulation head 18 can be used alternatively. Therefore, the convenience of use can be improved without using mistakes.
The basic structure of the cosmetic device of embodiment 13 other than the electrode shape and arrangement is the same as that of the cosmetic device of embodiment 1.
(effects of the cosmetic device described in the examples)
In the beauty appliance described in each of the above embodiments, the warm head 2 provided in the main body casing 1 includes the wide stimulation head 18 for applying the beauty stimulus to a large area of the skin surface and the narrow stimulation head 19 for applying the beauty stimulus to a small area of the skin surface. Skin contact bodies 22 and 32 for applying cosmetic stimulation to the skin surface are provided on the wide-area stimulation head 18 and the narrow-area stimulation head 19, respectively. According to such a cosmetic device, by using the wide stimulation head 18, it is possible to appropriately perform cosmetic treatment on a flat and large-area skin surface such as a cheek or a forehead, and also possible to appropriately perform cosmetic treatment on a narrow skin portion such as a portion around a nose or a portion around an eye by using the narrow stimulation head 19. Therefore, a beauty treatment appliance capable of performing a beauty treatment on the entire face skin can be provided. Further, since the dedicated skin contact bodies 22 and 32 are provided to the respective stimulation heads 18 and 19, the skin can be reliably heated and the electrical stimulation can be applied to the skin.
The electrode surface of the skin electrode 32 of the narrow-area stimulation head 19 is inclined with respect to the electrode surface of the skin contact 22 of the wide-area stimulation head 18. According to such a cosmetic device, when one stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) does not come into contact with the skin surface, and thus the cosmetic treatment can be appropriately performed by each stimulation head 18, 19.
The head surface 30 of the narrow stimulation head 19 supporting the skin contact body 32 is inclined relative to the head surface 20 of the wide stimulation head 18 supporting the skin contact body 22. According to such a cosmetic device, the wide stimulation head 18 and the narrow stimulation head 19 can be distinguished from each other according to the difference in the area of the stimulation heads 18 and 19 and the user can visually recognize the part to be treated for beauty using the narrow stimulation head 19 in particular. Therefore, it is possible to favorably prevent the use of the respective stimulation heads 18 and 19 by an incorrect use method.
The wide stimulation head 18 and the narrow stimulation head 19 are provided with temperature sensors 27 and 37 for detecting skin temperature, respectively. According to such a beauty treatment apparatus, since the temperature state of the skin contact bodies 22 and 32 in the respective stimulation heads 18 and 19 can be accurately detected, it is possible to surely prevent the skin temperature from increasing more than necessary, and to perform a beauty treatment safely.
Either one of the temperature sensor 27 provided in the wide stimulation head 18 and the temperature sensor 37 provided in the narrow stimulation head 19 also serves as an ambient temperature sensor in an environment where the cosmetic device is used. According to such a cosmetic device, for example, when cosmetic treatment is performed using the wide-area stimulation head 18, the temperature sensor 37 provided in the narrow-area stimulation head 19 detects the ambient temperature, and the operation state of the wide-area stimulation head 18 can be adjusted according to the season and the indoor temperature. For example, the following control and the like can be performed: the drive current supplied to the skin contact body 22 is adjusted to be higher than the reference output value in summer when the ambient temperature is high, and the drive current supplied to the skin contact body 22 is adjusted to be lower than the reference output value in winter. In the case of the thermal head 2 configured to provide the PTC heater isothermal heat source inside the skin contact body 22, the drive wave current supplied to the thermal source can be adjusted to correspond to the difference in the environmental temperature.
High-frequency voltage is applied to the skin contact bodies 22, 32, and the skin is heated by the heating action of the high-frequency current flowing through the skin. According to such a cosmetic device, since the skin can be heated from the inside by the heat generation action of the high-frequency current flowing through the skin, the skin can be heated quickly and efficiently, as compared with a case where the skin is heated by the heat conduction action from the skin surface toward the inside of the skin by, for example, pressing the heated thermal head 2 against the skin surface.
The skin contact bodies 22, 32 of the respective stimulation heads 18, 19 are constituted by the first electrodes 23, 33 and the second electrodes 24, 34, and the control unit 48 adjusts the supply state of the high-frequency current to the respective skin contact bodies 22, 32 in accordance with the threshold value of the detection signal of the temperature sensors 27, 37. In addition, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow stimulator head 19 is set to be smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide stimulator head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 of the narrow-area stimulating head 19 is set to be small, the temperature of the narrow-area stimulating head 19 can be controlled from a lower temperature stage than that of the wide-area stimulating head 18, and the narrow-area stimulating head 19 can be prevented from falling into a high temperature state.
In the adjacent portion between the wide-area stimulating head 18 and the narrow-area stimulating head 19, the second electrode 24 on the wide-area stimulating head 18 side and the second electrode 34 on the narrow-area stimulating head 19 side are integrally formed to constitute a common electrode 36. According to the thermal head 2, as compared with the case where the second electrodes 24 and 34 are provided independently on the respective stimulation heads 18 and 19, the number of parts can be reduced and the electrode structure can be simplified, and accordingly, the cost of the beauty appliance can be reduced. The height of protrusion of each of the electrodes 23 and 24 from the head surface 20 in the wide-area stimulation head 18 is set to be equal to the height of protrusion of the second electrode 24 constituting the common electrode 36 from the head surface 20, or greater than the height of protrusion of the second electrode 24 constituting the common electrode 36 from the head surface 20. The protruding height of each of the electrodes 33 and 34 in the narrow stimulation head 19 from the head surface 30 is set to be smaller than the protruding height of the second electrode 24 on the wide stimulation head 18 side constituting the common electrode 36 from the head surface 20. According to such a cosmetic device, the plane (plane in contact with the skin) connecting the first electrode 33 of the narrow stimulation head 19 and the second electrode 34 of the common electrode 36 can be made to intersect with the plane (plane in contact with the skin) connecting the first electrode 23 of the wide stimulation head 18 and the second electrode 24 of the common electrode 36. Therefore, for example, when cosmetic treatment is performed using the narrow stimulation head 19, the electrodes 23 and 24 of the wide stimulation head 18 can be favorably prevented from coming into contact with the skin surface.
The head surface 30 of the narrow stimulation head 19 is set to be gradually lower from the adjacent portion of the second electrodes 24 and 34 constituting the common electrode 36 over the tip of the narrow stimulation head 19. According to such a cosmetic device, the posture of the warm head 2 in close contact with the skin is greatly different between the case of using the wide stimulation head 18 and the case of using the narrow stimulation head 19, and thus, the electrodes 23 and 24 of the wide stimulation head 18 can be more reliably prevented from coming into contact with the skin surface when the cosmetic treatment is performed using the narrow stimulation head 19.
When the head surface 30 on the narrow stimulation head 19 side is tilted backward with respect to the head surface 20 on the wide stimulation head 18 side, the posture of the cosmetic device when the stimulation heads 18 and 19 are brought into contact with the skin surface is further greatly changed, and when the cosmetic treatment is performed using the narrow stimulation head 19, the electrodes 23 and 24 of the wide stimulation head 18 can be more reliably prevented from coming into contact with the skin surface.
In the adjacent portion between the wide-area stimulating head 18 and the narrow-area stimulating head 19, the second electrode 24 on the wide-area stimulating head 18 side and the second electrode 34 on the narrow-area stimulating head 19 side are integrally formed to constitute a common electrode 36. In addition, a temperature sensor 27 for detecting the skin temperature is provided inside the common electrode 36. According to the beauty appliance, compared with the case that the temperature sensors 27 and 37 are respectively and independently arranged on the stimulating heads 18 and 19, the number of parts is reduced, the electrode structure is simplified, and accordingly, the cost of the beauty appliance can be reduced.
The temperature sensor 27 provided in the common electrode 36 also serves as an ambient temperature sensor in an environment where the cosmetic device is used. According to such a beauty appliance, the control unit 48 can recognize the ambient temperature of the use environment of the user from the temperature detected by the temperature sensor 27 immediately after the power button unit 5 is turned on, and can adjust the drive current supplied to the skin contact body 22 in a state suitable for the ambient temperature.
The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with skin contact sensors for detecting contact between the skin contact bodies 22 and 32 and the skin surface. According to such a beauty appliance, the high-frequency current supplied to the skin-contacting bodies 22 and 32 can be adjusted according to the presence or absence of the detection signal of the skin contact sensor, or the threshold value of the detection signal of the temperature sensor 27 or 37 can be adjusted, so that the high-frequency current supplied to the skin-contacting bodies 22 and 32 can be optimized, and unnecessary power consumption can be reduced.
The skin contact body 22 of the broad area stimulation head 18 and/or the skin contact body 32 of the narrow area stimulation head 19 doubles as a skin contact sensor. When the skin contact bodies 22, 32 of the respective stimulation heads 18, 19 are in contact with the skin surface, the control unit 48 adjusts the high-frequency current supplied to the skin contact bodies 22, 32 or adjusts the threshold value of the detection signal of the temperature sensor 27 based on the detection signal output from the skin contact bodies 22, 32. According to such a beauty appliance, the skin-contacting bodies 22, 32 of the respective stimulation heads 18, 19 can be used to detect the contact of the skin-contacting bodies 22, 32 with the skin surface, and the number of parts can be reduced and the structure of the thermal head 2 can be simplified as compared with the case where a skin contact sensor is separately provided, and accordingly, the cost of the beauty appliance can be reduced.
In the adjacent portions of the head surfaces 20, 30 of the respective stimulation heads 18, 19, the second electrode 24 on the wide-area stimulation head 18 side and the second electrode 34 on the narrow-area stimulation head 19 side are formed by bent continuous planes. According to the thermal head 2, as compared with the case where the second electrodes 24 and 34 are provided independently on the respective stimulation heads 18 and 19, the number of parts can be reduced and the electrode structure can be simplified, and the processing cost of the second electrodes 24 and 34 can be reduced, which in turn can reduce the cost of the cosmetic device.
The first electrodes 23, 33 and the second electrodes 24, 34 of the respective stimulation heads 18, 19 are formed integrally, respectively. According to such a beauty appliance, as compared with the case where the electrodes 23, 24, 33, and 34 are formed independently of each other, the number of parts constituting the thermal head 2 can be reduced, and the cost required for manufacturing the beauty appliance can be reduced.
The skin contact body 22 of the broad area stimulation head 18 is configured by a first electrode 23 disposed at the center of the head surface 20 and a plurality of second electrodes 24 disposed around the first electrode 23, and at least one second electrode 24 constitutes a common electrode 36. According to the cosmetic device, since the periphery of the first electrode 23 is surrounded by the plurality of second electrodes 24, the cosmetic treatment can be appropriately performed with the cosmetic liquid held between the first electrode 23 and the second electrodes 24. In addition, when the thermal head 2 is slid along the skin surface to perform the cosmetic treatment, the cosmetic liquid can be prevented from being pushed away by the first electrode 23 and the second electrode 24.
The first electrode 23 of the wide-area stimulation head 18 is formed in a polygonal shape, and a plurality of second electrodes 24 are arranged around the electrode 23 at predetermined intervals. The corner 23a of the first electrode 23 faces the adjacent slit of the second electrode 24. According to such a beauty treatment instrument, when a beauty treatment is performed while the warm head 2 is slid along the skin surface, the beauty treatment liquid entering from the gap adjacent to the second electrode 24 is branched at the corner portion 23a, and one of the sides can be discharged to the outside of the skin contact body 22 while flowing along the periphery of the first electrode 23. Therefore, the replacement of the cosmetic liquid between the first electrode 23 and the second electrode 24 is facilitated, and the cosmetic effect of the cosmetic device can be improved.
The corner 23a of the first electrode 23 is located more inward than an imaginary outer contour line H2 connecting the outer edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warm head 2 along the skin surface, the cosmetic liquid to be introduced from the gap adjacent to the second electrode 24 is guided to flow at the corner portion 23a, and can be sent between the first electrode 23 and the second electrode 24. Therefore, the receiving amount of the cosmetic liquid around the second electrode 24 between the first electrode 23 and the second electrode 24 can be increased.
The corner 23a of the first electrode 23 is located more inward than an imaginary outer contour H1 connecting the inner edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warm head 2 along the skin surface, the cosmetic liquid entering from the gap adjacent to the second electrode 24 is guided to flow at the corner portion 23a, and can be held between the first electrode 23 and the second electrode 24. Therefore, as described above, more cosmetic liquid can be received and held between the first electrode 23 and the second electrode 24, compared to the case where the corner portion 23a of the first electrode 23 is located further inside than the imaginary outer contour line H2 connecting the outer edges of the second electrode 24.
The warm head 2 having the wide stimulation head 18 and the narrow stimulation head 19 is provided on the front surface of the main body housing 1, and the cold head 3 for cooling the skin surface is provided on the rear surface of the main body housing 1. According to such a beauty appliance, it is not necessary to prepare a beauty appliance having a hot and cold head 3 separately from a beauty appliance having a warm and hot head 2, and the warm and hot heads 2 and 3 can be used separately by merely changing the front and rear postures of the hand-held main body casing 1. For example, after cosmetic treatment is performed while the skin is heated by the thermal head 2, the heat-conducting surface 43 of the thermal head 3 can be cooled by being brought into close contact with the skin surface.
In embodiment 1, the corner 23a of the first electrode 23 is located inward of the imaginary outer contour line H1 on the inner edge side of the second electrode 24, but at least the corner 23a need not be located inward of the imaginary outer contour line H2 on the outer edge side of the second electrode 24. In this case, when the cosmetic treatment is performed while sliding the warm head 2 along the skin surface, the cosmetic liquid to be introduced from the gap adjacent to the second electrode 24 is guided to flow at the corner portion 23a, and can be fed between the first electrode 23 and the second electrode 24. Therefore, the receiving amount of the cosmetic liquid around the second electrode 24 between the first electrode 23 and the second electrode 24 can be increased.
The skin contact bodies 22 and 32 are not limited to metal, and may be formed of plastic or rubber. In the above-described embodiment, the wide stimulation head 18 and the narrow stimulation head 19 are provided in the head housing 17 fixed to the front portion of the base housing 16 of the main body housing 1, but this is not required, and the stimulation heads 18 and 19 may be provided in the main body housing 1. In this case, the head surfaces 20, 30 of the respective stimulation heads 18, 19 are provided in the main body housing 1. In the beauty appliance of embodiment 1, the high-frequency current is supplied to the skin contact members 22 and 32, but a piezoelectric element may be provided inside to apply ultrasonic vibration to the skin contact members 22 and 32. Further, an ion introduction function and an ion extraction function may be added.
