Problems to be solved by the invention

In the beauty treatment device of patent document 1, RF electrodes for applying beauty stimulation are disposed in a checkered pattern on the outer surface of a transmissive plate. Therefore, it is possible to perform a cosmetic treatment on a flat and large-area skin surface such as a cheek and a forehead without any trouble. However, if not all the contact sensors are in contact with the skin, no high-frequency current is supplied to the RF electrode. Therefore, it is impossible to apply a cosmetic treatment to a small skin portion around the nose, around the eyes, or the like by using a part of the RF electrode, and thus it is impossible to apply a cosmetic treatment to the entire facial skin.

The present invention provides a cosmetic device which can make a warm head cling to flat and large-area skin surfaces such as cheeks and forehead, and can make the warm head cling to narrow skin parts such as the periphery of a nose and eyes, so as to comprehensively carry out cosmetic treatment on the whole face skin.

The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with first electrodes 23, 33 and second electrodes 24, 34 constituting the skin contact bodies 22, 32, respectively. The control unit 48 adjusts the supply state of the high-frequency current to the skin contact bodies 22 and 32 based on the threshold value of the detection signal of the temperature sensor 27 and 37 provided in each of the stimulation heads 18 and 19.

The protruding height of the first electrode 33 and the second electrode 34 in the narrow-area stimulation head 19 from the head surface 30 is set smaller than the protruding height of the second electrode 24 on the wide-area stimulation head 18 side constituting the common electrode 36 from the head surface 20.

The head surface 30 of the narrow-band stimulation head 19 is set so as to gradually decrease from the adjacent portion of the second electrode 24 on the wide-band stimulation head 18 side constituting the common electrode 36 and the second electrode 34 on the narrow-band stimulation head 19 side constituting the common electrode 36 over the head end of the narrow-band stimulation head 19.

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. As the skin contact sensor, a capacitance type contact sensor, a sensor that detects the sinking of an electrode when the skin is pressed by the electrode, or the like can be applied.

The skin contact 22 of the broad field stimulation head 18 and/or the skin contact 32 of the narrow field 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 signals output from the skin contact bodies 22, 32.

The head surface 30 on the narrow-field stimulation head 19 side is tilted backward relative to the head surface 20 on the wide-field stimulation head 18 side. 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, which are provided in the adjacent portions of the both-head surfaces 20, 30, are formed by bent continuous planes.

The first electrode 23 of the broad area stimulation head 18 constituting the skin contact 22 and the first electrode 33 of the narrow area stimulation head 19 constituting the skin contact 32 are formed as one piece, and the second electrode 24 of the broad area stimulation head 18 constituting the skin contact 22 and the second electrode 34 of the narrow area stimulation head 19 constituting the skin contact 32 are formed as one piece.

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.

The corner 23a of the first electrode 23 is located further inside than the virtual outer contour line H2 connecting the outer edges of the second electrode 24.

The corner 23a of the first electrode 23 is located further inside than the virtual outer contour line H1 connecting the inner edges of the second electrodes 24.

A warming head 2 is provided on the front surface of the main body casing 1, and the warming head 2 includes a wide-area stimulation head 18 and a narrow-area stimulation head 19 for applying cosmetic stimulation to the skin surface. A cold/hot head 3 for cooling the skin surface is provided on the rear surface of the main body casing 1.

The effects of the invention are as follows.

In the beauty treatment device of the present invention, a wide-area stimulation head 18 for applying beauty treatment stimulation to a large area of the skin surface and a narrow-area stimulation head 19 for applying beauty treatment stimulation to a small area of the skin surface are provided in a warming head 2 provided in a main body casing 1. The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with skin contact bodies 22 and 32, respectively, which apply stimulation to the skin surface. According to such a beauty treatment device, by using the wide-area stimulation head 18, it is possible to properly perform beauty treatment of a flat and large-area skin surface such as a cheek and a forehead, and also to properly perform beauty treatment of a narrow skin portion such as a nose and an eye periphery by using the narrow-area stimulation head 19. Therefore, a cosmetic device capable of performing cosmetic treatment on the entire facial skin in an overall manner can be provided. Further, since the dedicated skin contact bodies 22, 32 are provided in the respective stimulation heads 18, 19, the skin can be appropriately heated.

The electrode surface of the skin contact 32 of the narrow-range stimulation head 19 is tilted with respect to the electrode surface of the skin contact 22 of the wide-range stimulation head 18. According to such a beauty treatment device, when the one stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) is inclined and separated from the skin surface in accordance with the inclination, so that the other stimulation head 19 (or 18) does not come into contact with the skin surface, and the beauty treatment can be properly performed by the stimulation heads 18, 19.

The head surface 30 of the narrow-band stimulation head 19 supporting the skin contact 32 is tilted with respect to the head surface 20 of the wide-band stimulation head 18 supporting the skin contact 22. According to such a beauty treatment device, in addition to the areas of the stimulation heads 18 and 19, the wide-area stimulation head 18 and the narrow-area stimulation head 19 can be distinguished from each other according to the difference in inclination, and in particular, the user can intuitively recognize the target site of the beauty treatment using the narrow-area stimulation head 19. Therefore, the stimulation heads 18 and 19 can be prevented from being used by the wrong use method.

Temperature sensors 27 and 37 for detecting skin temperature are provided in the wide-area stimulation head 18 and the narrow-area stimulation head 19, respectively. According to such a beauty treatment device, the temperature state of the skin contact bodies 22, 32 in the respective stimulation heads 18, 19 can be accurately detected, so that the skin temperature can be reliably prevented from being increased beyond necessity, and the beauty treatment can be safely performed.

Either one of the temperature sensor 27 provided to the wide-area stimulation head 18 and the temperature sensor 37 provided to the narrow-area stimulation head 19 serves as an environmental temperature sensor of the environment in which the beauty apparatus is used. According to such a beauty treatment device, for example, when performing beauty treatment 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 operating state of the wide-area stimulation head 18 can be adjusted according to the difference in seasons and the difference in indoor temperature. For example, the following control and the like can be performed: in summer with a high ambient temperature, the drive wave current to the skin contact 22 is adjusted to be higher than the reference output value, and in winter, the drive wave current to the skin contact 22 is adjusted to be lower than the reference output value. In the case of the warming head 2 configured by providing a heat source such as a PTC heater inside the skin contact body 22, the drive wave current to be supplied to the heat source can be adjusted to correspond to the difference in the ambient temperature.

The skin contacts 22, 32 are applied with a high-frequency voltage, and the skin is heated by the heat generation effect 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 effect of the high-frequency current flowing to the skin, the skin can be heated more quickly and efficiently than, for example, the case where the heated thermal head 2 is pressed against the skin surface and the skin is heated by the heat conduction effect from the skin surface toward the inside of the skin.

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 section 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-range stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide-range stimulation head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 of the narrow-range stimulation head 19 is set to be small, the temperature control of the narrow-range stimulation head 19 can be controlled from a stage of a lower temperature than the wide-range stimulation head 18, and the narrow-range stimulation head 19 can be prevented from being brought into a high-temperature state.

The common electrode 36 is formed by integrating 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 in the adjacent portion between the wide-area stimulation head 18 and the narrow-area stimulation head 19. According to the warming head 2, the number of parts can be reduced and the electrode structure can be simplified, compared with the case where the second electrodes 24 and 34 are provided independently for the respective stimulation heads 18 and 19, and accordingly, the cost of the beauty apparatus can be reduced. The protruding height of each electrode 23, 24 in the wide-area stimulation head 18 from the head surface 20 is set to be the same as the protruding height of the second electrode 24 constituting the common electrode 36 from the head surface 20, or greater than the protruding height of the second electrode 24 constituting the common electrode 36 from the head surface 20. The protruding height of each electrode 33, 34 in the narrow-area stimulation head 19 from the head surface 30 is set smaller than the protruding height of the second electrode 24 on the wide-area stimulation head 18 side constituting the common electrode 36 from the head surface 20. According to such a beauty treatment device, the plane (the plane in contact with the skin) connecting the first electrode 33 of the narrow-area stimulation head 19 and the second electrode 34 constituting the common electrode 36 can be made to intersect the plane (the plane in contact with the skin) connecting the first electrode 23 of the wide-area stimulation head 18 and the second electrode 24 constituting the common electrode 36. Therefore, for example, in the case of performing cosmetic treatment using the narrow-area stimulation head 19, the electrodes 23 and 24 of the wide-area stimulation head 18 can be satisfactorily prevented from coming into contact with the skin surface.

The head surface 30 in the narrow-band stimulation head 19 is set to gradually become lower from the adjacent portions of the second electrodes 24, 34 constituting the common electrode 36 throughout the head end of the narrow-band stimulation head 19. According to such a beauty treatment device, the posture of the warming head 2 that is in close contact with the skin differs greatly between the case of using the wide-area stimulation head 18 and the case of using the narrow-area stimulation head 19, and thus, when performing the beauty treatment using the narrow-area stimulation head 19, the electrodes 23, 24 of the wide-area stimulation head 18 can be prevented from coming into contact with the skin surface even more reliably.

When the head surface 30 on the narrow-area stimulation head 19 side is tilted backward with respect to the head surface 20 on the wide-area stimulation head 18 side, the posture of the beauty instrument when the stimulation heads 18 and 19 are in contact with the skin surface is further greatly different, and when the narrow-area stimulation head 19 is used for the beauty treatment, the electrodes 23 and 24 of the wide-area stimulation head 18 can be further reliably prevented from being in contact with the skin surface.

In the adjacent portion between the wide-area stimulation head 18 and the narrow-area stimulation head 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 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 such a beauty treatment device, the number of parts can be reduced and the electrode structure can be simplified, compared with the case where the temperature sensors 27, 37 are provided independently for the respective stimulation heads 18, 19, and accordingly, the cost of the beauty treatment device can be reduced.

The temperature sensor 27 provided on the common electrode 36 doubles as an environmental temperature sensor of the environment in which the beauty apparatus is used. In such a beauty appliance, the control unit 48 can recognize the ambient temperature of the use environment of the user based on the detected temperature of the temperature sensor 27 immediately after the power button unit 5 is turned on, and can adjust the drive current to the skin contact members 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 treatment device, the drive current to the skin contact 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 and 37 is adjusted, so that the drive current to the skin contact bodies 22 and 32 can be optimized, and unnecessary power consumption can be reduced.

The skin contact 22 of the broad field stimulation head 18 and/or the skin contact 32 of the narrow field stimulation head 19 doubles as a skin contact sensor. When the skin contact bodies 22, 32 of the respective stimulation heads 18, 19 are brought into 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 signals output from the skin contact bodies 22, 32. According to such a beauty treatment device, the skin contact bodies 22, 32 of the respective stimulation heads 18, 19 can detect the contact of the skin contact bodies 22, 32 with the skin surface, and therefore, compared with the case where a skin contact sensor is separately provided, the number of parts can be reduced, and the structure of the warming head 2 can be simplified, and accordingly, the cost of the beauty treatment device 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 warming head 2, the number of parts can be reduced, the electrode structure can be simplified, and the processing cost of the second electrodes 24, 34 can be reduced, as compared with the case where the second electrodes 24, 34 are provided independently for the respective stimulation heads 18, 19, respectively, and accordingly the cost of the beauty appliance can be reduced.

The first electrodes 23, 33 and the second electrodes 24, 34 of the respective stimulation heads 18, 19 are integrally formed, respectively. According to such a beauty treatment device, the number of components constituting the warming head 2 can be reduced, and the cost required for manufacturing the beauty treatment device can be reduced, as compared with the case where the electrodes 23, 24, 33, 34 are formed independently.

The skin contact 22 of the wide-area stimulation head 18 is configured by a first electrode 23 disposed in the center of the head surface 20 and a plurality of second electrodes 24 disposed around the first electrode 23, and at least one of the second electrodes 24 configures a common electrode 36. According to such a beauty treatment device, since the periphery of the first electrode 23 is surrounded by the plurality of second electrodes 24, the beauty treatment can be properly performed in a state where the beauty treatment liquid is held between the first electrode 23 and the second electrode 24. In addition, when the cosmetic treatment is performed while the warming head 2 is slid along the skin surface, the cosmetic liquid can be satisfactorily 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. And, the corner 23a of the first electrode 23 is made to face the adjacent slit of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warming head 2 along the skin surface, the cosmetic liquid flowing in from the adjacent slit of the second electrode 24 is branched at the corner 23a, and can flow along the periphery of the first electrode 23 and flow out of the skin contact member 22. Therefore, the replacement of the cosmetic liquid between the first electrode 23 and the second electrode 24 is promoted, and the cosmetic effect of the cosmetic device can be improved.

The corner 23a of the first electrode 23 is positioned further inside than the virtual 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 warming head 2 along the skin surface, the cosmetic liquid to be introduced from the adjacent slit of the second electrode 24 is guided to flow at the corner 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 corner 23a of the first electrode 23 is positioned further inside than the virtual outer contour line H1 connecting the inner edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warming head 2 along the skin surface, the cosmetic liquid entering from the adjacent slit of the second electrode 24 is guided to flow at the corner 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 than in the case where the corner 23a of the first electrode 23 is located further inside than the virtual outer contour line H2 connecting the outer edges of the second electrode 24.

A warming head 2 having a wide-area stimulation head 18 and a narrow-area stimulation head 19 is provided on the front surface of the main body casing 1, and a cooling/heating head 3 for cooling the skin surface is provided on the rear surface of the main body casing 1. According to such a cosmetic device, it is not necessary to prepare a cosmetic device having the cold/hot head 3 separately from a cosmetic device having the warm head 2, and the warm head 2 and the cold/hot head 3 can be used separately by merely changing the front-rear posture of the hand holding the main body casing 1.

The skin electrode 22 is composed of a regular hexagonal first electrode 23 disposed at the center of the electrode base 21, and six isosceles trapezoid second electrodes 24 disposed around each side of the first electrode 23. The six second electrodes 24 are formed integrally, and adjacent second electrodes 24 are continuous with each other via a connecting portion (shown by a broken line) provided inside the wide-area stimulation 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 further inside than the virtual outer contour line H1 of the hexagon connecting the inner edges of the second electrodes 24. In this way, when the corner 23a faces the adjacent slit of the second electrode 24, the cosmetic liquid applied to the facial skin can be smoothly introduced from the adjacent slit of the second electrode 24 to the liquid holding portion 26, and the skin surface between the first electrode 23 and the second electrode 24 on which the high-frequency current acts can be thermally stimulated, and the cosmetic liquid can be applied to the skin surface, thereby improving the cosmetic effect. As described above, the same effect can be exhibited by applying the first electrode 23 of the wide-area stimulation head 18 to a cosmetic appliance having no narrow-area stimulation head 19 but only the wide-area stimulation head 18, in which the first electrode 23 is formed into a polygonal shape and a plurality of second electrodes 24 are arranged around the polygonal shape at predetermined intervals, in which the corner 23a of the first electrode 23 is located further inward than the virtual outer contour line H2 connecting the outer edges of the second electrodes 24, and in which the corner 23a of the first electrode 23 is located further inward than 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 bulged from the surface of the electrode stage 21, whereas the second electrode 24 is provided in a state of being buried in a holder frame 25 bulged and formed in 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 protrude from the surface of the electrode base 21, respectively, and can hold a cosmetic liquid such as a cosmetic liquid 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 temperature of the skin 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-band stimulation head 19 includes a semicircular head surface 30 continuous with the head surface 20 of the wide-band stimulation head 18, an electrode base 31 bulging inside the head surface 30, a skin electrode (skin contact body) 32 arranged on the surface of the electrode base 31 and heating the skin surface, and the like. The head surface 30 is formed of a curved surface that bulges slightly obliquely upward, and the head surface 30 as a whole is tilted backward with respect to the head surface 20 of the wide-area stimulation head 18. In fig. 1, the upper portion of the both surfaces 20 and 30 than the dividing line b is a narrow-area stimulation head 19. In this embodiment, the head surface 30 of the narrow-field stimulation head 19 is tilted back about 45 degrees relative to the head surface 20 of the wide-field 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 is composed of a first electrode 33 having an upward semicircular shape disposed on the upper half side of the electrode base 31, and a second electrode 34 having a downward semicircular shape disposed on the lower side of the first electrode 33, and the electrodes 33 and 34 are provided so as to be buried in a holder frame 35 formed to bulge out of the electrode base 31, and the surfaces thereof are exposed so as to be flush with the holder frame 35. The second electrode 34 is formed integrally with the second electrode 24 on the upper portion of the wide-area stimulation head 18 to constitute a common electrode 36. A temperature sensor 37 such as a thermistor for detecting the temperature of the skin 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 base 21 in the same manner as the first electrode 23. As described above, the surfaces of the skin contact bodies 22 and 32 that come into contact with the skin become electrode surfaces (skin contact surfaces), and the area of the electrode surfaces of the skin contact body 32 is set smaller than the area of the electrode surfaces of the skin contact body 22.

(Cold and hot head)

In fig. 3, the cold/hot head 3 is constituted by a peltier element 40, a cold/hot head 41 disposed on the rear surface of the peltier element 40 and transmitting cold/heat to the skin surface, a radiator 42 disposed on the front surface of the peltier element 40 and releasing heat, and the like. The cold-hot head 41 is made of an aluminum die-cast molding, and the heat conducting surface 43 thereof is exposed outside the mounting window of the rear case 1 b. The heat sink 42 is constituted by a die-cast molded product of aluminum, and releases the warmth of the peltier element 40 via a set of heat radiating fins. The rear case 1b is provided with a discharge window for discharging warm air to the outside of the case, but this is not shown. An acceleration sensor 45 for detecting the condition of the beauty appliance in use is provided on the upper and lower sides of the inside of the main body casing 1.

(Control part)

As shown in fig. 5 and 6, the beauty treatment device is provided with a control unit 48 for controlling the operating states of the heating head 2 and the cooling head 3. When the power button unit 5 is turned on, the warm-up operation mode is started, and the control unit 48 applies a high-frequency voltage to the skin electrode 22 of the wide-range stimulation head 18 and the skin electrode 32 of the narrow-range stimulation head 19 via the high-frequency output unit 49, and causes the mode display unit 8 on the warm-up operation mode side to light up. When the level switching button unit 7 is turned on, the control unit 48 cyclically switches the voltages of the high-frequency voltages 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. Meanwhile, 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 treatment apparatus 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, forehead, or the like coated with the lotion, the cosmetic water, and 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, 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 allows the skin to be heated by the high-frequency current flowing between the pair of electrodes 23 and 24. The beauty stimulus in this case is both warm stimulus and electrical stimulus. The control unit 48 can recognize whether or not the beauty treatment 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 wide-area stimulation head 18 is being applied to the skin based on the current value detected by the current value detection unit 50 (see fig. 6). In contrast, in a state where the narrow-band stimulation head 19 is stuck to the skin surface, the control unit 48 can recognize whether or not the narrow-band stimulation head 19 is stuck to 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 electrode 22 of the wide-area stimulation head 18 and the skin electrode 32 of the narrow-area stimulation head 19, and thereafter turns off the power supply at a time after a predetermined time elapses.

When the detection signal from one of the two acceleration sensors 45 is not output for a predetermined period of time, the control unit 48 may reduce or stop the supply of the high-frequency current to the skin electrodes 22 and 32 because the thermal head 2 is not moved in a state of being brought into contact with the facial skin. As shown in fig. 7, when the detection signal from the current value detection unit 50 is larger than the threshold value (reference current value), the control unit 48 determines that the skin electrode 22 of the wide-area stimulation head 18 among the skin electrodes 22, 32 is in contact with the skin surface, and increases the output value of the high-frequency current (supplied 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 beauty apparatus is not in operation, and the supply of the high-frequency current is reduced or stopped. In contrast, 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-band stimulation head 19 of the skin electrodes 22, 32 is in contact with the skin surface, and the output value of the high-frequency current (supplied power) supplied to the skin electrode 32 is made lower than the reference output value. This is because: the area and heat capacity of the skin electrode 32 of the narrow-band stimulation head 19 are small, and the heat radiation area is small, so that the temperature tends to rise easily, and if a high-frequency current equal to that of the skin electrode 22 of the wide-band stimulation head 18 is supplied to the skin electrode 32, the degree of rise in skin temperature due to the skin electrode 32 is large, and as will be described later, there is a concern that the control unit 48 temporarily falls into an overshoot state even if the control unit 48 receives a detection signal from the temperature sensor 37 and performs temperature control. In this way, in the control of the control unit 48 of the present embodiment, it 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 current value flowing to the skin between the first electrode 23 and the second electrode 24 in the wide-area stimulation head 18 and the current value flowing to 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-range stimulation head 19 is in contact with the skin, the control unit 48 supplies the narrow-range stimulation head 19 with supply power in a state reduced from the supply power to the wide-range stimulation head 18. In contrast, when detecting that the wide-area stimulation head 18 is in contact with the skin, the control unit 48 supplies the power supplied to the wide-area stimulation head 18 in a state that is greater than the power supplied to the narrow-area stimulation head 19. That is, when either the wide-area stimulation head 18 or the narrow-area stimulation head 19 is in contact with the skin, the power corresponding to the heads can be automatically supplied from the high-frequency output unit 49. Therefore, the trouble of switching the supplied power by manual operation can be saved. Further, since the switching is not forgotten, an unnecessary increase in the 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 are also used as skin contact sensors, but the skin contact sensors may be configured such that a dedicated sensor such as a capacitance type contact sensor is provided independently of the skin electrodes 22 and 32.

When the detection signal of either one of the temperature sensors 27 and 37 exceeds the threshold value while the wide-area stimulation head 18 or the narrow-area stimulation head 19 is being used, the control unit 48 reduces the supply state of the high-frequency current (supplied power) to the skin electrode 22 or the skin electrode 32, thereby preventing the skin temperature from increasing. If the detection signal is equal to or lower than the threshold value, the supply state of the high-frequency current is returned to the initial state, and after the detection signal exceeds the threshold value again, the supply state of the high-frequency current is lowered. By repeating the above-described operations, 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-range stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide-range stimulation head 18. In this way, the threshold values of the detection signals of the temperature sensors 27, 37 in the respective stimulation heads 18, 19 are made different in order to avoid the following cases: 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 tends to rise easily, 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 due to the skin electrode 32 is large, and therefore there is a concern that the temperature of the skin in contact with the skin electrode 32 becomes high. That is, when a high-frequency current is supplied to the skin electrode 32 of the narrow-band stimulation head 19, since the threshold value of the temperature sensor 37 is set to be low, even if an overshoot is generated, the skin temperature can be prevented from becoming high.

As described above, at least one of the structure for preventing the skin temperature from rising by making the threshold values of the temperature sensors 27 and 37 different from each other and the structure for making the supply state of the high-frequency current to the skin electrode 22 of the wide-range stimulation head 18 and the skin electrode 32 of the narrow-range stimulation head 19 different from each other may be provided, but in the present embodiment, both the former structure and the latter structure are provided. When the temperature rise of the narrow-band stimulation head 19 is suppressed by changing the supply state of the high-frequency current, the amount of the high-frequency voltage applied or the amount of the high-frequency current supplied can be greatly suppressed, and the balance between heating and heat radiation can be adjusted, so that the skin temperature does not rise beyond the required level without the temperature control of the sensor. The control unit 48 can recognize the ambient temperature of the user's use environment by the unused temperature sensor 37 of the narrow-band 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, the drive current supplied to the skin electrode 22 is adjusted to be higher than the reference output value as indicated by the upward open arrow in fig. 7, and in winter, the drive current supplied to the skin electrode 22 is adjusted to be lower than the reference output value as indicated by the downward open arrow in fig. 7. 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-band stimulation head 19, but can recognize the ambient temperature by using the temperature sensor 27 of the skin electrode 22 on the use side. In this case, the temperature sensor 27 is used as an original temperature sensor for temperature control when the skin electrode 22 is pressed against the skin surface, by detecting and recognizing the ambient temperature immediately after the power button unit 5 is turned on and adjusting the supply state of the high-frequency current in advance.

After a predetermined time has elapsed, the control unit 48 drives a sounding body, not shown, and notifies the user that an operation time corresponding to the set operation mode has elapsed. Similarly, by attaching the skin electrode 32 of the narrow-area stimulation head 19 to the periphery of the nose, the eyes, or the like, or by sliding along the facial skin, the skin can be heated by the high-frequency current flowing to the skin between the pair of electrodes 33, 34, and the entire facial skin can be subjected to the cosmetic treatment.

The area of the skin electrode 32 of the narrow-band stimulation head 19 is significantly smaller than the area of the skin electrode 22 of the wide-band stimulation head 18, and the narrow-band stimulation head 19 is largely tilted backward with respect to the wide-band stimulation head 18, so that the skin electrode 32 of the narrow-band stimulation head 19 can be smoothly and properly subjected to the beauty treatment of the narrow portion. Further, since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current is supplied to the skin electrode 32 as when the skin electrode 22 of the wide-area stimulation head 18 is brought into close contact with the skin surface, the electric power converted into heat between the electrodes 33 and 34 increases, and the degree of rise of the skin temperature per unit time increases, and there is a concern that the skin is unnecessarily heated. In order to eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow-band stimulation head 19 is being stuck to the skin based on the current value of the current value detection unit 50, and makes the high-frequency current supplied to the skin electrode 32 lower than the high-frequency current supplied to the skin electrode 22. In addition, the threshold of the temperature sensor 37 of the narrow-range stimulation head 19 is set lower than the threshold of the temperature sensor 27 of the wide-range stimulation head 18 to prevent the skin from being unnecessarily heated.

After the cosmetic treatment of the wide-area stimulation head 18 and the narrow-area stimulation head 19 is completed, the operation mode is switched from the warm operation mode to the hot operation mode by the on operation of the mode button unit 6, and the driving current is supplied to the peltier element 40, so that the mode display lamp 8 on the hot operation mode side is turned on. The heat conduction surface 43 of the cold/hot head 41 is cooled by being brought into close contact with the facial skin in a state where the temperature of the heat conduction surface 43 is reduced to the use temperature after a predetermined time elapses. When a predetermined time elapses from the supply of the driving current to the Xiang Paer patch element 40, the supply of the driving current is stopped, the cooling process of the cold/hot head 41 on the facial skin is ended, and the power button part 5 is pressed to turn off all the operation modes.

Example 2

Fig. 8 shows example 2 of the beauty apparatus of the present invention. The beauty treatment device of example 2 is different from the beauty treatment device of example 1 in that a temperature sensor 27 is disposed inside a 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, and accordingly, the manufacturing cost of the beauty apparatus can be reduced. Further, since the control unit 48 can recognize the ambient temperature of the user's use environment based on the temperature detected by the temperature sensor 27 immediately after the power button unit 5 is turned on, the driving current supplied to the skin electrode 22 can be adjusted to be suitable for 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 set independently, respectively, but in the present embodiment, the threshold values of the detection signals may be set independently as well. Specifically, based on the detection signal of the skin contact detection unit composed of 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-area stimulation head 18 contacts 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-area stimulation head 19 contacts the skin surface. That is, the threshold value of the detection signal of the temperature sensor 27 when the narrow-area stimulation head 19 is used is set smaller than when the wide-area stimulation head 18 is used. Thus, as in the cosmetic device of example 1, an unnecessary increase in temperature of the skin surface can be prevented. The control unit 48 can recognize the ambient temperature of the user's use environment from 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 to be appropriate for the ambient temperature, as in the beauty apparatus of embodiment 1.

Example 3

Fig. 9 shows example 3 of the beauty apparatus of the present invention. The cosmetic device of embodiment 3 is different from the cosmetic device of embodiment 1 in that the head surface 30 of the narrow-area stimulation head 19 is formed of a curved surface continuous with the head surface 20 of the wide-area stimulation head 18, and the head surface 30 is slightly tilted backward as a whole. Thus, the head surface 30 of the narrow-range stimulation head 19 may also be slightly reclined without requiring substantial recline.

Example 4

Fig. 10 to 12 show embodiment 4 of the beauty apparatus of the present invention. In the beauty treatment apparatus of this embodiment 4, a wide-area stimulation head 18 and a narrow-area stimulation head 19 are provided on one head surface 20. Specifically, the triangular first electrode 23 is provided in the center of the head surface 20, and the three second electrodes 24 constituting the skin electrode 22 of the wide-area stimulation head 18 and the three second electrodes 34 constituting the skin electrode 32 of the narrow-area stimulation head 19 are alternately arranged around the triangular first electrode, 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 edge 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, 34, the protrusion height h1 of the first electrode 23 from the head surface 20 is highest, and the protrusion height h2 of the second electrode 24 from the head surface 20 and the protrusion height h3 of the second electrode 34 from the head surface 20 are set to be sequentially lower. The skin contact surface of the first electrode 23 is inclined to a different degree in accordance with the difference in the protruding height h2 of the second electrode 24 and the protruding 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-area stimulation head 18 side is prevented from contacting the skin, especially in the case of using the narrow-area stimulation head 19 having a small electrode area.

Example 5

Fig. 13 and 14 show example 5 of the beauty apparatus of the present invention. In the beauty treatment device of example 5, the head surface 30 of the narrow-area stimulation head 19 and the head surface 20 of the wide-area stimulation head 18 are formed in a square shape with a rounded quadrangle, and the head surface 30 of the narrow-area stimulation head 19 is tilted backward with respect to the head surface 20 of the wide-area stimulation head 18 as in the beauty treatment device of example 1. The wide-area stimulation head 18 is provided with a square first electrode 23 and a second electrode 24 parallel to the left, right and lower sides of the first electrode 23. The narrow-band stimulation head 19 is provided with a first electrode 33 and a second electrode 34 each of which is laterally long. The first electrode 23 of the wide-area stimulation head 18 is integrally formed with the first electrode 33 of the narrow-area stimulation head 19, and a connection portion (see a broken line) connecting the electrodes 23 and 33 is disposed in the interior of the warming head 2 in a hidden state. Similarly, 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, 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 34 are disposed in the interior of the warming 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 example 6 of the beauty apparatus of the present invention. In the beauty treatment instrument of example 6, the head surface 30 of the narrow-area stimulation head 19 and the head surface 20 of the wide-area stimulation head 18 are formed in an oblong shape longer up and down, and the head surface 30 of the narrow-area stimulation head 19 is tilted backward with respect to the head surface 20 of the wide-area stimulation head 18, as in the beauty treatment instrument of example 1. The first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are integrally exposed from the head surfaces 20 and 30, and are formed in an oblong shape longer up and down. In addition, the second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 of the narrow-area stimulation head 19 are formed integrally so as to be exposed from the head surfaces 20, 30, and are formed in an endless ring shape longer in the up-down direction. A temperature sensor 27 is disposed inside the bent portion of the first electrodes 23, 33. In the present embodiment, since the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are integrally formed, the number of components can be reduced and the electrode structure can be simplified, as compared with the case where the electrodes 23 and 33 are separately provided, and accordingly the cost of the beauty apparatus 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 the case where the electrodes 24 and 34 are separately provided, and accordingly, the cost of the beauty apparatus can be reduced.

In example 6, the same control as in example 1 was also performed. That is, as shown in fig. 7, when the detection signal outputted from the current value detection unit 50 is larger than the threshold value (reference current value), the control unit 48 determines that the skin electrode 22 of the wide-area stimulation head 18 among the skin electrodes 22, 32 is in contact with the skin surface, and increases the output value of the high-frequency current (supplied power) supplied to the skin electrode 22 to the reference output value or more. In contrast, 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-band stimulation head 19 of the skin electrodes 22, 32 is in contact with the skin surface, and the output value of the high-frequency current (supplied power) supplied to the skin electrode 32 is made lower than the reference output value. Since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current is supplied to the skin electrode 32 as when the skin electrode 22 of the wide-area stimulation head 18 is brought into close contact with the skin surface, the electric power converted into heat between the electrodes 33 and 34 increases, and there is a concern that the skin is unnecessarily heated. In order to eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow-band stimulation head 19 is being stuck to the skin based on the current value of the current value detection unit 50, and makes the high-frequency current supplied to the skin electrode 32 lower than the high-frequency current supplied to the skin electrode 22. In embodiment 1, since the first electrodes 23 and 33 are independent, there is a large difference between the area and heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide-area stimulation head 18. Therefore, the skin electrode 32 of the narrow-area stimulation head 19 having a small heat radiation area tends to easily rise in temperature. However, in the case of the present embodiment, since the first electrodes 23, 33 and the second electrodes 24, 34 are integrally connected, the temperature rise of the skin electrode 32 of the narrow-band stimulation head 19 is not as high as that of embodiment 1.

Example 7

Fig. 16 and 17 show example 7 of the beauty apparatus of the present invention. In the beauty treatment device of example 7, the skin contact body 22 of the wide-area stimulation head 18 and the skin contact body 32 of the narrow-area stimulation head 19 are configured in a continuous state in a droplet shape in the head housing 17, PTC heaters 53 and 54 serving as warm heat sources are disposed inside the respective skin contact bodies 22 and 32, and temperature sensors 27 and 37 are disposed adjacent thereto. Although not shown, skin contact sensors are provided in the respective stimulation heads 18 and 19, and the PTC heater 53 (or 54) on the side from which the detection signal of the skin contact sensor is output is driven, so that warm stimulation can be applied to the skin surface. In the present embodiment, the skin contact bodies 22, 32 are constituted by the housing surfaces made of plastic material of the wide-area stimulation head 18 and the narrow-area stimulation head 19 without the metal skin electrodes 22, 23. The skin contact members 22, 32 are not limited to metal, and may be made of plastic material, rubber, or the like. The beauty device of the present invention may be a beauty device 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 is only warm stimulus. In this way, there are cases where the cosmetic stimulus is only warm.

Example 8

Fig. 18 shows example 8 of the beauty apparatus of the present invention. In the beauty treatment instrument of embodiment 8, the head surfaces 20, 30 are formed of perpendicular flat surfaces orthogonal to the central axis of the base housing 16, and a narrow-area stimulation head 19 of a small area is provided at the upper portion thereof, and the remainder is a wide-area stimulation head 18. Inside the wide-area stimulation head 18 and the narrow-area stimulation head 19, nichrome wire heaters 55 and 56 for heating the skin contact bodies 22 and 32 are disposed, respectively. The skin contact 22 of the wide-area stimulation head 18 and the skin contact 22 of the narrow-area stimulation head 19 are on the same surface, but the external shape and area thereof are greatly different. In the beauty treatment device of embodiment 1, the head surfaces 20 and 30 can be constituted by flat surfaces, as in the beauty treatment device of the present embodiment. The beauty instrument of example 8 can apply thermal stimulation (beauty stimulation) to the skin surface by using the skin contact bodies 22, 32 heated by the nichrome wire heaters 55, 56.

Fig. 19 shows example 9 of the beauty apparatus of the invention. In the beauty treatment device of embodiment 9, a wide-area stimulation head 18 is provided on the upper portion of the front surface of the main body casing 1, a narrow-area stimulation head 19 is provided on the upper portion of the rear surface of the main body casing 1, a pair of first electrodes 23 and second electrodes 24 are provided on the stimulation head 18, and a pair of first electrodes 33 and second electrodes 34 are provided on the stimulation head 19. Thus, the wide-area stimulation head 18 and the narrow-area stimulation head 19 can also be independently arranged at different positions of the main body casing 1.

Example 10

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

Example 11

Fig. 21 shows example 11 of the beauty apparatus of the present invention. In the beauty treatment device of embodiment 11, a changeover switch 57 is provided between the high-frequency output portion 49 and the first electrodes 23 and 33, and an electrode selection switch 59 is provided in the main body case 1. According to this beauty treatment device, the control unit 48 operates the skin electrode 22 (or the skin electrode 32) on the side designated by the user by switching the electrode selection switch 59 by the user and switching the switching switch 57.

Example 12

Fig. 22 shows embodiment 12 of the beauty apparatus of the invention. In the beauty treatment device of example 12, the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are formed integrally, the second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 of the narrow-area stimulation head 19 are formed integrally, and the former electrodes 23, 33 and the latter electrodes 24, 34 are arranged on the head surfaces 20, 30 in a state of being adjacent to each other in the left-right direction. The surface area of the former electrodes 23 and 33 is set to be larger than the surface area of the latter electrodes 24 and 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 external contour line surrounding the periphery of each skin electrode 22, 32 is oval. The surface area of each electrode 23, 24, 33, 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, 30. The temperature sensors 27, 37 are disposed inside the second electrodes 24, 34. As shown in fig. 22, the skin electrode 32 on the narrow-area stimulation head 19 side is tilted backward with respect to the skin electrode 22 on the wide-area stimulation head 18 side. As described above, the basic structure of the beauty apparatus of example 12 other than the electrode shape and arrangement is the same as that of the beauty apparatus of example 1.

In the beauty treatment device of example 12, a high-frequency current is supplied between the first electrode 23 of the broad-band stimulation head 18 and the second electrode 24 of the broad-band 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-band stimulation head 19 and the second electrode 34 of the narrow-band stimulation head 19, and the skin surface is heated from the inside. Since the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are formed by bent continuous planes, the cross section of the electrode surface (skin contact surface) of the first electrodes 23, 33 of the respective stimulation heads 18, 19 takes a "dogleg" shape. 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 formed of bent continuous planes, the cross section of the electrode surfaces (skin contact surfaces) of the second electrodes 24, 34 of the respective stimulation heads 18, 19 has a "dogleg" shape. The electrode surfaces of the first electrodes 23 and 33 and the second electrodes 24 and 34 need not be flat surfaces, and may be formed of curved surfaces protruding outward. The first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be formed of flat surfaces, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be formed of outwardly protruding curved surfaces. 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 that have a curvature larger than that of the curved surfaces of the electrodes 23 and 24. According to the beauty treatment device in which at least the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 are formed by the outwardly protruding curved surfaces, when the beauty treatment is performed by the narrow-area stimulation head 19, the beauty treatment of the skin portion having the recess around the nose or the like can be appropriately performed. Further, at least one side of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 is formed by an outwardly protruding curved surface. Accordingly, the skin portion having the recess 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 at 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, the positions of the left and right bent portions are the same as shown in fig. 22, but may be slightly offset vertically. The outwardly convex curved surfaces of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be formed of compound arcs having different curvatures, and the outwardly convex curved surfaces of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be formed of compound arcs having different curvatures. In particular, with respect to the outwardly protruding curved surfaces of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19, if the curvature on the side of the curved portion is set to be small and the curvature is configured to be larger from the middle to the end of the curved portion, the skin portion having the recess can be accurately treated. The first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be configured such that the curved surface of the bent portion side is formed as an inward concave curved surface, and the outward convex curved surface is continuously connected to the inward concave curved surface from the middle of the bent portion. Accordingly, the skin portion can be subjected to warm stimulation at a point. The surfaces of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 corresponding thereto may be flat surfaces or may be curved surfaces protruding outward. According to such a beauty treatment tool, when the narrow-area stimulation head 19 performs a beauty treatment, the beauty treatment of the skin portion having the recess around the nose or the like can be performed appropriately.

In example 12, the same control as in example 1 was also performed. That is, as shown in fig. 7, when the detection signal outputted from the current value detection unit 50 is larger than the threshold value (reference current value), the control unit 48 determines that the electrode surface (skin contact surface) of the skin electrode 22 of the wide-area stimulation head 18 among the skin electrodes 22, 32 is in contact with the skin surface, and increases the output value of the high-frequency current (supplied power) supplied to the skin electrode 22 to the reference output value or more. In contrast, 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-band stimulation head 19 of the skin electrodes 22, 32 is in contact with the skin surface, and the output value of the high-frequency current (supplied power) supplied to the skin electrode 32 is made lower than the reference output value. This is because: since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current is supplied to the skin electrode 32 as when the skin electrode 22 of the wide-area stimulation head 18 is brought into close contact with the skin surface, the electric power converted into heat between the electrodes 33 and 34 increases, and there is a concern that the skin is unnecessarily heated. In order to eliminate such a problem, as described above, the control unit 48 detects that the skin electrode 32 of the narrow-band stimulation head 19 is being stuck to the skin based on the current value of the current value detection unit 50, and makes the high-frequency current supplied to the skin electrode 32 lower than the high-frequency current supplied to the skin electrode 22. In embodiment 1, since the first electrodes 23 and 33 are independent, there is a large difference between the area and heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide-area stimulation head 18. Therefore, the skin electrode 32 of the narrow-area stimulation head 19 having a small heat radiation area tends to easily rise in temperature. However, in the case of the present embodiment, the first electrodes 23, 33 and the second electrodes 24, 34 are integrally connected, so that the temperature rise of the skin electrode 32 of the narrow-band stimulation head 19 is not as high as in embodiment 1.

As in embodiment 1, in embodiment 12, 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-range stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide-range stimulation head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 provided in the narrow-band stimulation head 19 is set to be small, the temperature of the skin in contact with the skin electrode 32 can be prevented from being high when the high-frequency current is supplied to the skin electrode 32 of the narrow-band stimulation head 19.

The beauty treatment device of example 12 can be implemented as follows.

The wide-area stimulation head 18 is provided with a first electrode 23 and a second electrode 24 which constitute the skin contact body 22, and the narrow-area stimulation head 19 is provided with a first electrode 33 and a second electrode 34 which constitute the skin contact body 32, the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19, and 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 and formed in a long-axis shape, the first electrodes 23, 33 and the second electrodes 24, 34 are arranged side by side with a predetermined interval therebetween, and the total value of the surface areas of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 constituting the skin contact body 22 is set to be larger than the total value of the surface areas of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 constituting the skin contact body 32.

According to the beauty treatment device of example 12, by using the wide-area stimulation head 18, it is possible to properly perform beauty treatment of a flat and large-area skin surface such as a cheek and a forehead, and also to properly perform beauty treatment of a narrow skin portion such as a nose and an eye periphery by using the narrow-area stimulation head 19.

In the beauty treatment appliance of embodiment 12, the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are formed of a bent continuous plane. And, the second electrode 24 of the broad field stimulation head 18 and the second electrode 34 of the narrow field stimulation head 19 are formed by bent continuous planes. According to such a warming head, the number of parts can be reduced and the electrode structure can be simplified, compared with the case where the first electrodes 23, 33 and the second electrodes 24, 34 are provided independently for the respective stimulation heads 18, 19, and accordingly, the cost of the beauty apparatus can be reduced. Further, since the skin contact surface of the skin electrode 32 of the narrow-area stimulation head 19 is inclined with respect to the skin contact surface of the skin electrode 22 of the wide-area stimulation head 18, when the single stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) can be prevented from coming into contact with the skin surface, and the respective stimulation heads 18, 19 can be properly subjected to the cosmetic treatment.

In the beauty treatment device of embodiment 12, the temperature sensor 27 is provided in at least one of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18, and the temperature sensor 37 is provided in at least one of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19. In addition, the threshold value of the temperature sensor 37 provided in the narrow-range stimulation head 19 is set smaller than the threshold value of the temperature sensor 27 provided in the wide-range stimulation head 18. According to such a warming head, when a high-frequency current is supplied to the skin electrode 32 of the narrow-band stimulation head 19, since the threshold value of the temperature sensor 37 is set low, it is possible to prevent the temperature of the skin in contact with the skin electrode 32 from becoming high.

When the skin electrode 32 of the narrow-band stimulation head 19 is being applied to the skin, the high-frequency current supplied to the skin electrode 32 is made lower than the high-frequency current supplied to the skin electrode 22. According to such a warming head, since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current is supplied to the skin electrode 32 as when the skin electrode 22 of the wide-area stimulation head 18 is brought into close contact with the skin surface, the electric power converted into heat between the electrodes 33, 34 becomes large, and there is a concern that the skin is unnecessarily heated, but the warming head can prevent this.

Example 13

Fig. 23 shows example 13 of the beauty apparatus of the present invention. In the beauty treatment device of example 12, the wide-area stimulation head 18 is provided at the upper portion of the main body casing 1, and the narrow-area stimulation head 19 is provided at the upper end of the main body casing 1, and the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 are each constituted by rotatable rollers. Specifically, the first electrodes 23 and the second electrodes 24 of the wide-area stimulation head 18 are alternately arranged two by two, respectively, 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 casing 1. Similarly, the first electrode 33, the insulating roller 63, and the second electrode 34 of the narrow-band stimulation head 19 are sequentially arranged, 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 casing 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 the width and diameter 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 constituted of two first electrodes 23 and two second electrodes 24, so that the contact area of the skin electrode 22 with the skin is 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 width dimensions of 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 are the same, but the diameters of the first electrode 23 and the second electrode 24 on the skin electrode 22 side are set larger than the diameters of the first electrode 33 and the second electrode 34 on the skin electrode 32 side, so that the contact areas of the skin electrode 22 and the skin electrode 32 with the skin are different in size. The diameters of the electrodes 23, 24, 33, 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, 32 with the skin may be different. The cross-sectional shape of each electrode 23, 24, 33, 34 may be polygonal. The cross-sectional shape of each electrode 23, 24, 33, 34 may be circular as it is, and a plurality of convex portions or concave portions may be uniformly provided on the peripheral surface. Thus, a skin irritation effect can be expected.

In the present embodiment, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow-band stimulation head 19 are integrally rotated, but as a modification, the three may be rotated independently. Thus, when the narrow-band stimulation head 19 is moved on the skin surface, the direction can be smoothly switched. 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 integrally rotated, but may be rotated independently. However, when considering the quality and cost aspects, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow-area stimulation head 19 are integrally rotatable units, whereas the two first electrodes 23, the two second electrodes 24, and the three insulating rollers 61 in the wide-area stimulation head 18 are integrally rotatable units of the first electrode 23, the second electrode 24, and the insulating rollers 61 on the left side, and the first electrode 23, the second electrode 24, and the insulating rollers 61 on the right side are integrally rotatable units of the wide-area stimulation head 18, so that the wide-area stimulation head is independently rotatable left and right. The center insulating roller 61 may be rotatable integrally with either one of the left and right units, or may be rotatable independently.

In the present embodiment, the narrow-band stimulation head 19 is fixed, but as a modification, the narrow-band stimulation head 19 is configured to be retractable in the up-down direction with respect to the main body casing 1. In this case, the first electrode 33, the insulating roller 63, and the second electrode 34 are extended and contracted together with the roller shaft 62 with respect to the main body casing 1. The roller shaft 62 is provided with a pitch structure (protruding portion) at a portion located inside the main body casing 1, and can be positioned at three positions, i.e., a lower position, an intermediate position, and a higher position, by engagement with the pitch structure (three recessed portions) corresponding to the inside of the main body casing 1. By this telescopic structure, the narrow-area stimulation head 19 can be separated from the wide-area stimulation head 18, so that the wide-area stimulation head 18 does not become an obstacle when the narrow-area stimulation head 19 is used, and the convenience of use is improved. The narrow-range stimulation head 19 can be completely stored in the main body casing 1. In this case, the degree of articulation is four. This structure can be utilized to protect the narrow-range stimulation head 19. The wide-area stimulation head 18 is fixed in this embodiment, but may be configured to be extendable and retractable in the same manner as the narrow-area stimulation head 19 described above. The expansion and contraction direction in this case is the front-rear direction.

In the present embodiment, the narrow-band stimulation head 19 is fixed, but as a modification, the narrow-band stimulation head 19 may be elastically biased in the up-down direction toward the main body casing 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 casing 1. Specifically, two coil springs (springs) are provided in the main body case 1, and the springs are inserted into the left and right ends of the roller shaft 62, and are pressed against two contact pieces fixed to the left and right ends of the roller shaft 62, thereby elastically biasing the narrow-area stimulation head 19 upward. The two contact pieces contact the inner wall around the opening of the main body housing 1 of the loose fitting roller shaft 62 to restrict upward movement. Thereby, the upward movement of the entire narrow-range stimulation head 19 is restricted. When the narrow-range stimulation head 19 is pressed against the skin, the narrow-range stimulation head 19 is lowered relative to the main body casing 1 by the pressing force, so that the concave-convex of the skin can be followed, and the burden imposed on the skin can be reduced. The wide-area stimulation head 18 is fixed in this embodiment, but can be configured to receive elastic force in the same manner as the narrow-area stimulation head 19 described above. The direction of the elastic force in this case is the front-rear direction rather than 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 in the narrow-area stimulation head 19 and/or the wide-area stimulation head 18. Thus, when the vibrator is operated in the warm stimulation, the narrow-area stimulation head 19 and/or the wide-area stimulation head 18 can vibrate in a direction in which the elastic force is applied, so that stimulation due to small-amplitude vibration 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 diameter of the first electrode 23 at the left end and the diameter of the second electrode 24 at the right end are kept unchanged, and the diameters of the second electrode 24 and the first electrode 23 on the inner side (near the center) can be set to a size larger by one turn than the diameters of the first electrode 23 at the left end and the second electrode 24 at the right end. This facilitates all the electrodes to be in contact with the skin surface (e.g., under the jaw) of the recess portion, and thereby enables appropriate application of thermal stimulation to the skin.

In the present embodiment, the narrow-range stimulation head 19 and the wide-range stimulation head 18 are driven rotary structures in which the electrodes 23, 24, 33, 34 are configured by rollers and are rotated by pressing them against the skin and moving them, but may be configured to be actively rotated by providing power such as a motor.

In the present embodiment, the narrow-area stimulation head 19 is provided on the upper surface wall of the main body casing 1, and the wide-area stimulation head 18 is provided on the front surface wall of the main body casing 1, but the narrow-area stimulation head 19 may be provided on the rear surface wall of the main body casing 1.

For example, a square frame is rotatably attached to the roller shaft 64, and the narrow-area stimulation head 19 may be rotatably provided on one side of the upper side of the frame, and the wide-area stimulation head 18 may be rotatably provided on the lower side of the opposite side. The portions of the frame attached to the roller shaft 64 are the same as the left and right central portions of the frame. Thus, when the frame is rotated, the narrow-area stimulation head 19 or the wide-area stimulation head 18 can be used alternatively. Therefore, the usability can be improved without using errors.

The basic structure of the beauty apparatus of example 13 except for the electrode shape and arrangement is the same as that of the beauty apparatus of example 1.

(Effects of the beauty treatment tool described in examples)

In the beauty instrument described in the above embodiments, the warming head 2 provided in the main body casing 1 includes the wide-area stimulation head 18 for applying beauty stimulation to a large area of the skin surface, and the narrow-area stimulation head 19 for applying beauty stimulation to a small area of the skin surface. The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with skin contact bodies 22 and 32, respectively, which apply cosmetic stimulation to the skin surface. According to such a beauty treatment device, by using the wide-area stimulation head 18, it is possible to properly perform beauty treatment of a flat and large-area skin surface such as a cheek and a forehead, and also to properly perform beauty treatment of a narrow skin portion such as a nose and an eye periphery by using the narrow-area stimulation head 19. Therefore, a cosmetic device capable of performing cosmetic treatment on the entire facial skin in an overall manner can be provided. Further, since the individual skin contact bodies 22, 32 are provided in the respective stimulation heads 18, 19, the skin can be reliably heated and the skin can be electrically stimulated.

The electrode surface of the skin electrode 32 of the narrow-band stimulation head 19 is tilted with respect to the electrode surface of the skin contact 22 of the wide-band stimulation head 18. According to such a beauty treatment device, when the one stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) does not contact the skin surface, and thus the beauty treatment can be properly performed by the stimulation heads 18, 19.

The head surface 30 of the narrow-band stimulation head 19 supporting the skin contact 32 is tilted with respect to the head surface 20 of the wide-band stimulation head 18 supporting the skin contact 22. According to such a beauty treatment device, in addition to the difference in the areas of the stimulation heads 18 and 19, the wide-area stimulation head 18 and the narrow-area stimulation head 19 can be distinguished according to the difference in inclination, and in particular, the user can intuitively recognize the target site of the beauty treatment using the narrow-area stimulation head 19. Therefore, the stimulation heads 18 and 19 can be prevented from being used by the wrong use method.

Either one of the temperature sensor 27 provided to the wide-area stimulation head 18 and the temperature sensor 37 provided to the narrow-area stimulation head 19 serves as an environmental temperature sensor in an environment where the beauty apparatus is used. According to such a beauty treatment device, for example, when performing beauty treatment 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 operating state of the wide-area stimulation head 18 can be adjusted according to the difference in seasons and the difference in indoor temperature. For example, the following control and the like can be performed: in summer with a high ambient temperature, the drive current to the skin contact 22 is adjusted to be higher than the reference output value, and in winter, the drive current to the skin contact 22 is adjusted to be lower than the reference output value. In the case of the warming head 2 configured by providing a heat source such as a PTC heater inside the skin contact body 22, the drive wave current to be supplied to the heat source can be adjusted to correspond to the difference in the ambient temperature.

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 section 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-range stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide-range stimulation head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 of the narrow-range stimulation head 19 is set to be small, the temperature control of the narrow-range stimulation head 19 can be performed from a lower temperature stage than the wide-range stimulation head 18, and the narrow-range stimulation head 19 can be prevented from being brought into a high-temperature state.

The head surface 30 of the narrow-band stimulation head 19 is set so as to gradually become lower from the adjacent portions of the second electrodes 24, 34 constituting the common electrode 36 over the head end of the narrow-band stimulation head 19. According to such a beauty treatment device, the posture of the warming head 2 that is in close contact with the skin differs greatly between the case of using the wide-area stimulation head 18 and the case of using the narrow-area stimulation head 19, and thus, when performing the beauty treatment using the narrow-area stimulation head 19, the electrodes 23, 24 of the wide-area stimulation head 18 can be prevented from coming into contact with the skin surface even more reliably.

The temperature sensor 27 provided in the common electrode 36 also serves as an environmental temperature sensor in an environment where the beauty apparatus is used. According to such a beauty treatment device, the control unit 48 can recognize the ambient temperature of the use environment of the user based on the detected temperature of the temperature sensor 27 immediately after the power button unit 5 is turned on, and can adjust the drive current to the skin contact element 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 cosmetic device, the high-frequency current supplied to the skin contact 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 and 37 is adjusted, so that the high-frequency current supplied to the skin contact bodies 22 and 32 can be optimized, and unnecessary power consumption can be reduced.

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. And, the corner 23a of the first electrode 23 is made to face the adjacent slit of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warming head 2 along the skin surface, the cosmetic liquid entering from the adjacent slit of the second electrode 24 is branched at the corner 23a, and one of the branches can be discharged outside the skin contact member 22 while flowing around the first electrode 23. Therefore, the replacement of the cosmetic liquid between the first electrode 23 and the second electrode 24 is promoted, and the cosmetic effect of the cosmetic device can be improved.

The corner 23a of the first electrode 23 is positioned further inside than the virtual outer contour line H1 connecting the inner edges of the second electrode 24. According to such a cosmetic device, when performing a cosmetic treatment while sliding the warming head 2 along the skin surface, the cosmetic liquid entering from the adjacent slit of the second electrode 24 is guided to flow at the corner 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 than in the case where the corner 23a of the first electrode 23 is located further inside than the virtual outer contour line H2 connecting the outer edges of the second electrode 24 to each other.

A warming head 2 having a wide-area stimulation head 18 and a narrow-area stimulation head 19 is provided on the front surface of the main body casing 1, and a cooling/heating head 3 for cooling the skin surface is provided on the rear surface of the main body casing 1. According to such a cosmetic device, it is not necessary to prepare a cosmetic device having the cold/hot head 3 separately from a cosmetic device having the warm head 2, and the warm head 2 and the cold/hot head 3 can be used separately by merely changing the front-rear posture of the hand holding the main body casing 1. For example, after the skin is cosmetically treated while being heated by the warming head 2, the heat conduction surface 43 of the warming head 3 can be brought into close contact with the skin surface to be cooled.

In embodiment 1, the corner 23a of the first electrode 23 is located further inside than the virtual outer contour line H1 on the inner edge side of the second electrode 24, but this is not necessarily the case, and at least the corner 23a may be located further inside than the virtual outer contour line H2 on the outer edge side of the second electrode 24. In this case, when the skin care treatment is performed while the warming head 2 is slid along the skin surface, the flow of the cosmetic liquid to be introduced from the adjacent slit of the second electrode 24 is guided at the corner 23a, and the cosmetic liquid 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 members 22, 32 are not limited to metal, and may be formed of plastic or rubber. In the above-described embodiment, the wide-area stimulation head 18 and the narrow-area 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 the stimulation heads 18, 19 may be provided in the main body housing 1 without this. In this case, the head surfaces 20, 30 of the respective stimulation heads 18, 19 are provided in the main body casing 1. In the beauty treatment device of example 1, the high-frequency current is supplied to the skin contact bodies 22, 32, but a piezoelectric element may be provided inside so that ultrasonic vibration can be applied to the skin contact bodies 22, 32. In addition, an ion introduction function and an ion extraction function may be added.
