JP 2011-194173 A

In the cosmetic treatment apparatus of Patent Document 1, RF electrodes for applying cosmetic stimulus are arranged in a grid pattern on the outer surface of the transmission plate. Therefore, it is possible to carry out beauty treatment on a flat skin surface having a large area such as cheeks and forehead without any trouble. However, high-frequency current is not supplied to the RF electrodes unless all of the contact sensors are in contact with the skin. Therefore, using some of the RF electrodes, it is not possible to apply cosmetic treatment to narrow skin areas such as around the nose and around the eyes, and it is not possible to evenly apply cosmetic treatment to the entire facial skin.

The object of the present invention is to apply a thermal head not only to large flat skin surfaces such as the cheeks and forehead, but also to narrow skin areas such as around the nose and around the eyes, to evenly perform beauty treatment on the entire facial skin.

(thermal head)
The thermal head 2 integrally includes a cylindrical base case 16 fixed to the main body case 1 and a droplet-shaped head case 17 formed in front of the base case 16 when viewed from the front.

Equivalent effects can be exhibited by applying to a beauty instrument having only a wide-area stimulation head 18 without the narrow-area stimulation head 18 .

While the first electrode 23 is provided in a state of protruding from the surface of the electrode table 21, the second electrode 24 is provided in a state of being embedded in a holder frame 25 formed to protrude from the electrode table 21.

The first electrode 23 and the second electrode 24 are made of, for example, a titanium plate.

The narrow-area stimulation head 19 has a semicircular head surface 30 that is continuous with the head surface 20 of the wide-area stimulation head 18, an electrode base 31 that bulges inside the head surface 30, and is arranged on the surface of the electrode base 31. A skin electrode (skin contacting body) 32 for heating the skin surface is provided. The head surface 30 is a curved surface that slightly bulges obliquely upward, and the entire head surface 30 is tilted backward with respect to the head surface 20 of the wide area stimulation head 18 . In FIG. 1 , the portion above the boundary line b between the head surfaces 20 and 30 serves as the narrow-area stimulation head 19 . In this embodiment, the head surface 30 of the narrow stimulation head 19 is tilted backward by about 45 degrees with respect to the head surface 20 of the wide stimulation head 18 (see FIG. 4).

Although not shown, the rear case 1b has an opening for discharging heat to the outside of the case. Acceleration sensors 45 for detecting that the beauty instrument is in use are provided at the top and bottom inside the main body case 1 .

(control part)
As shown in FIGS. 5 and 6, the beauty tool is provided with a control section 48 for controlling the operational states of the thermal head 2 and the thermal head 3 . When the power button unit 5 is turned on, the thermal operation mode is activated, and the control unit 48 applies a high-frequency voltage to the skin electrodes 22 of the wide-area stimulation head 18 and the skin electrodes 32 of the narrow-area stimulation head 19 via the high-frequency output unit 49. is applied to turn on the mode indicator lamp 8 on the thermal operation mode side. Further, when the level switching button section 7 is turned on, the control section 48 cyclically switches the voltage of the high frequency voltage applied to the skin electrodes 22 and 32 in the order of weak, medium, and strong, and the selected high frequency voltage is applied to the skin. It is applied to the electrodes 22 and 32. At the same time, the lighting state of the level indicator lamp 9 is made to correspond to the level switching state.

With the beauty equipment prepared as described above, for example, the skin electrodes 22 of the wide area stimulation head 18 are applied to the facial skin such as cheeks and foreheads coated with emulsion or lotion, and are slid along the facial skin. Then, since the acceleration sensor 45 detects the motion, the controller 48 supplies a high frequency current between the pair of electrodes 23 and 24 . Specifically, a sinusoidal high-frequency voltage with a frequency of 1 MHz is applied between the first electrode 23 and the second electrode 24 or between the first electrode 33 and the second electrode 34 . Thereby, the skin can be heated by the high-frequency current flowing through the skin between the pair of electrodes 23 and 24 . The cosmetic stimulation in this case is both thermal stimulation and electrical stimulation. Based on the detection signal output from the acceleration sensor 45, the control unit 48 can recognize that the beauty equipment is being used. Also, from the current value detected by the current value detection unit 50 (see FIG. 6), the control unit 48 can recognize that the wide area stimulation head 18 is applied to the skin. Conversely, when the narrow-area stimulation head 19 is applied to the skin surface, the control unit 48 can recognize that the narrow-area stimulation head 19 is applied to the skin based on the detection signal of the current value detection unit 50 . can. The acceleration sensor 45 can be omitted. In that case, when the power button 5 is turned on, the control unit 48 starts the timer, applies a high-frequency voltage to the skin electrodes 22 of the wide-area stimulation head 18 and the skin electrodes 32 of the narrow-area stimulation head 19, and then Turn off the power when the time has elapsed.

If a detection signal is not output from one of the two acceleration sensors 45 for a certain period of time, the thermal head 2 may not move while still being applied to the skin. reduces or stops the supply of the high frequency current to the skin electrodes 22 and 32 . In addition, the control unit 48 constantly monitors the detection signal output from the current value detection unit 50, and as shown in FIG. , among the skin electrodes 22 and 32, it is determined that the skin electrode 22 of the wide area stimulation head 18 is in contact with the skin surface, and the output value of the high-frequency current (supplied power) supplied to the skin electrode 22 is Set to the reference output value or increase the reference output value or more. Furthermore, when no detection signal is output from both acceleration sensors 45, it is determined that the beauty device is not operating, and the supply of high-frequency current is reduced or stopped. Conversely, when the detection signal of the current value detection unit 50 is smaller than the threshold, it is determined that the skin electrode 32 of the narrow area stimulation head 19 is in contact with the skin surface among the skin electrodes 22 and 32, and The output value of the high frequency current (supplied power) supplied to the electrode 32 is reduced below the reference output value. This is because the area and heat capacity of the skin electrodes 32 of the narrow-area stimulation head 19 are small, and the heat radiation area is small, so that the temperature easily rises, and a high-frequency current equivalent to that of the skin electrodes 22 of the wide-area stimulation head 18 is supplied to the skin electrodes 32. In this case, the degree of skin temperature rise by the skin electrodes 32 is large, and even if the control unit 48 performs temperature control in response to a detection signal from the temperature sensor 37 as will be described later, there is a risk of temporarily overshooting. is. Thus, in the control by the control unit 48 of the present embodiment, the current value flowing through the skin between the first electrode 23 and the second electrode 24 in the wide area stimulation head 18 and the first electrode 33 in the narrow area stimulation head 19 Based on the current value flowing through the skin between the second electrodes 34, 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. After that, when the control unit 48 detects that the narrow-area stimulation head 19 is in contact with the skin, the control unit 48 supplies power to the narrow-area stimulation head 19 that is lower than the power supplied to the wide-area stimulation head 18 . supply to Conversely, when the control unit 48 detects that the wide area stimulation head 18 is in contact with the skin, the control unit 48 supplies the wide area stimulation head 18 with power that is greater than the power supplied to the narrow area stimulation head 19 . do. In other words, when one of the wide area stimulation head 18 and the narrow area stimulation head 19 is brought into contact with the skin, power corresponding to these heads can be automatically supplied from the high frequency output section 49 . Therefore, it is possible to save the trouble of manually switching the supplied power. In addition, since there is no forgetting to switch, an unnecessary rise in skin temperature can be reliably prevented. The current value detector 50 and the skin electrodes 22 and 32 constitute a skin contact detector. In this proposed example, the skin electrodes 22 and 32 also serve as skin contact sensors, but the skin contact sensors may have a configuration in which a dedicated sensor such as a capacitance type contact sensor is provided separately from the skin electrodes 22 and 32. .

If the detection signal from either one of the temperature sensors 27 and 37 exceeds the threshold while the wide area stimulation head 18 or the narrow area stimulation head 19 is being used, the controller 48 supplies the signal to the skin electrode 22 or the skin electrode 32 . To prevent the skin temperature from rising by lowering the supply state of the high-frequency current (supplied power) that is applied. When the detection signal becomes equal to or less than the threshold value, the supply state of the high frequency current is restored, and when the detection signal exceeds the threshold value again, the supply state of the high frequency current is lowered. By repeating this, the skin temperature becomes constant. In this proposed example, the threshold (operating temperature) of the temperature sensor 27 is set at 45°C, and the threshold (operating temperature) of the temperature sensor 37 is set at 43°C. That is, the threshold of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set smaller than the threshold of the detection signal of the temperature sensor 27 provided in the wide-area stimulation head 18 . The reason why the threshold values of the detection signals of the temperature sensors 27 and 37 in the stimulation heads 18 and 19 are different is that the area and heat capacity of the skin electrodes 32 of the narrow stimulation head 19 are small and the heat dissipation area is also small. The temperature tends to rise, and if a high-frequency current equivalent to that of the skin electrodes 22 of the wide-area stimulation head 18 is supplied to the skin electrodes 32, the degree of increase in skin temperature due to the skin electrodes 32 is large. This is to avoid the possibility of the temperature becoming too high. That is, when a high-frequency current is supplied to the skin electrodes 32 of the narrow-area stimulation head 19, the threshold value of the temperature sensor 37 is set low, so even if an overshoot occurs, the skin temperature can be prevented from becoming high.

As described above, the temperature sensors 27 and 37 have different threshold values to prevent the skin temperature from rising. At least one of the configurations for differentiating the supply state of the high-frequency current to the skin electrodes 32 of 19 is sufficient, but in the proposed example, both the former configuration and the latter configuration are provided. When suppressing the temperature rise of the narrow-area stimulation head 19 by varying the state of high-frequency current supply, the amount of high-frequency voltage applied or the amount of high-frequency current supplied is greatly reduced to adjust the balance between heating and heat release. It can be set so that the skin temperature does not rise more than necessary without temperature control by the sensor. In addition, the temperature sensor 37 of the narrow stimulation head 19, which is not in use, for example, allows the control unit 48 to recognize the environmental temperature of the user's usage environment. The supply state of the driving current supplied to the electrodes 22 can be adjusted. For example, in summer, the drive current supplied to the skin electrode 22 is adjusted higher than the reference output value, as indicated by the upward white arrow in FIG. 7, and in winter, as indicated by the downward white arrow in FIG. , the driving current supplied to the skin electrode 22 is adjusted to be lower than the reference output value. In this proposed example, the temperature sensor 37 of the narrow-area stimulation head 19 that is not in use causes the control unit 48 to recognize the environmental temperature of the user's usage environment. The environmental temperature can be recognized by the sensor 27 . In this case, the environmental temperature is detected and recognized immediately after the power button 5 is turned on, and the supply state of the high-frequency current is adjusted in advance. 27 is used as the temperature sensor for the original temperature control.

Thereafter, after a predetermined period of time has elapsed, the control unit 48 drives a sounding body (not shown) to inform the user that the operation time corresponding to the set operation mode has elapsed. Similarly, by applying the skin electrodes 32 of the narrow-area stimulation head 19 around the nose and around the eyes, or by sliding them along the facial skin, the skin is stimulated by the high-frequency current flowing between the pair of electrodes 33 and 34. By heating, the entire facial skin can be evenly treated for beauty.

The area of the skin electrodes 32 of the narrow-area stimulation head 19 is considerably smaller than the area of the skin electrodes 22 of the wide-area stimulation head 18, and furthermore, the narrow-area stimulation head 19 is greatly tilted backward with respect to the wide-area stimulation head 18. , the skin electrodes 32 of the narrow-area stimulating head 19 can be used to smoothly and accurately perform beauty treatments on narrow areas. In addition, since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current as when applying the skin electrode 22 of the wide-area stimulation head 18 to the skin surface is supplied to the skin electrode 32, the electrodes 33 and 34 will be The amount of electric power converted into heat increases, and the degree of increase in skin temperature per unit time increases, so there is a risk that the skin will be heated unnecessarily. In order to solve such a problem, the control unit 48 detects from the current value of the current value detection unit 50 that the skin electrode 32 of the narrow-area stimulation head 19 is applied to the skin, as described above. The high frequency current supplied to the skin electrode 32 is made smaller than the high frequency current supplied to the skin electrode 22 . Furthermore, the threshold of the temperature sensor 37 of the narrow stimulation head 19 is set lower than the threshold of the temperature sensor 27 of the wide stimulation head 18 to prevent unnecessary heating of the skin.

After the cosmetic treatment by the wide area stimulation head 18 and the narrow area stimulation head 19 is completed, the operation mode is switched from the heat operation mode to the cold heat operation mode by turning on the mode button section 6, and the drive current is supplied to the Peltier device 40. and the mode indicator lamp 8 on the cooling/heating mode side is turned on. After a predetermined time has passed and the temperature of the heat transfer surface 43 of the cooling head 41 is lowered to the operating temperature, the heat transfer surface 43 is applied to the face to cool it. When a predetermined time elapses after the drive current is supplied to the Peltier element 40, the supply of the drive current is stopped, so the cooling process of the facial skin by the cooling head 41 is terminated, and the power button section 5 is pressed to turn on all the parts. Turn off the driving mode.

(Proposal Example 2) FIG. 8 shows a proposal example 2 of the beauty instrument. The beauty instrument of Proposed Example 2 differs from the beauty instrument of Proposed Example 1 in that temperature sensor 27 is arranged inside common electrode 36 . In this way, when the temperature sensor 27 is arranged inside the common electrode 36, one temperature sensor can be used regardless of whether the wide area stimulation head 18 or the narrow area stimulation head 19 is used. Since the skin temperature can be detected by 27, the manufacturing cost of the beauty instrument can be reduced by the amount that the temperature sensor 37 can be omitted. Further, since the control unit 48 can recognize the environmental temperature of the usage environment of the user from the temperature detected by the temperature sensor 27 immediately after the power button unit 5 is turned on, the environmental temperature , the drive current supplied to the skin electrode 22 can be adjusted. In Proposal Example 1, the threshold for the detection signal of the temperature sensor 27 and the threshold for the detection signal of the temperature sensor 37 are set separately, but in the present Proposal Example as well, the threshold for the detection signal can be set separately. Specifically, based on a detection signal from a skin contact detection unit consisting of the current detection unit 50 and the skin electrodes 22 and 23, the control unit 48 determines that if the skin electrode 22 of the wide area stimulation head 18 is in contact with the skin surface, the temperature sensor 27 If the threshold value of the detection signal is set to 45° C., for example, and the skin electrode 32 of the narrow area stimulation head 19 is in contact with the skin surface, the threshold value of the detection signal of the temperature sensor 27 is set to 43° C., for example. That is, the threshold value of the detection signal of the temperature sensor 27 is set smaller when using the narrow-area stimulation head 19 than when using the wide-area stimulation head 18 . As a result, it is possible to prevent an unnecessary increase in the temperature of the skin surface, as in the case of the beauty tool of Proposed Example 1. In addition, since the control unit 48 can recognize the environmental temperature of the user's usage environment from the temperature detected by the temperature sensor 27 immediately after the power button 5 is turned on, it is compatible with the environmental temperature, as in the case of the beauty tool of Proposal Example 1. By doing so, the driving current supplied to the skin electrodes 22 and 23 can be adjusted.

(Proposal Example 3) FIG. 9 shows Proposal Example 3 of the beauty instrument. The beauty device of Proposed Example 3 is characterized in that the head surface 30 of the narrow-area stimulation head 19 is formed by a curved surface that is continuous with the head surface 20 of the wide-area stimulation head 18, and the entire head surface 30 is slightly tilted backward. , different from the beauty instrument of Proposed Example 1. Thus, the head surface 30 of the narrow-area stimulation head 19 does not have to be greatly tilted backwards, and may be tilted slightly backwards.

(Proposal Example 4) Figs. 10 to 12 show Proposal Example 4 of the beauty instrument. In the beauty instrument of Proposed Example 4, a single head surface 20 is provided with a wide area stimulation head 18 and a narrow area stimulation head 19 . Specifically, a triangular first electrode 23 is provided in the center of the head surface 20, and around it are three second electrodes 24 that constitute the skin electrode 22 of the wide area stimulation head 18 and the skin of the narrow area stimulation head 19. The three second electrodes 34 constituting the electrode 32 are arranged alternately so that the second electrodes 24 can be shared. The second electrode 24 of the wide area stimulation head 18 is arranged parallel to the side of the first electrode 23, and the second electrode 34 of the stimulation head 19 is arranged facing the corner 23a of the first electrode 23. there is

As shown in FIG. 12, among the electrodes 23, 24, and 34, the projection height h1 of the first electrode 23 from the head surface 20 is the highest, and the projection height h2 of the second electrode 24 from the head surface 20 is the highest. , and the protrusion height h3 of the second electrode 34 from the head surface 20 are set lower in the order of description. In addition, the skin contact surface of the first electrode 23 is formed by varying the degree of inclination of the curved surface according to the difference between the protrusion height h2 of the second electrode 24 and the protrusion height h3 of the second electrode 34. By sloping the skin contact surface of 23 downward toward each electrode 24, 34, the first electrode 23 on the side of the wide area stimulation head 18 comes into contact with the skin, especially when using the narrow area stimulation head 19 with a small electrode area. to avoid doing so.

(Proposal Example 5) Figs. 13 and 14 show Proposal Example 5 of the beauty instrument. In the beauty instrument of Proposed 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 rectangular shape with rounded corners. The head surface 30 of the regional stimulation head 19 is tilted backward with respect to the head surface 20 of the wide area stimulation head 18.例文帳に追加The wide area stimulation head 18 is provided with a rectangular first electrode 23 and second electrodes 24 parallel to the left and right side portions and the lower side portion of the first electrode 23 . In addition, the narrow area stimulation head 19 is provided with a horizontally long first electrode 33 and a second electrode 34, respectively. 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, and the connecting portion (see broken line) connecting the electrodes 23 and 33 is hidden inside the thermal head 2. It is placed in an upright position. 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 the connection portion (see the broken line) connecting the adjacent second electrodes 24 and the second electrode 24 A connecting portion (see a broken line) connecting the electrode 24 and the second electrode 34 is hidden inside the thermal head 2 . Temperature sensors 27 and 37 are arranged inside the first electrodes 23 and 33 .

(Proposal Example 6) FIG. 15 shows a proposal example 6 of the beauty instrument. In the beauty instrument of Proposed 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 that is elongated vertically. Head surface 30 of stimulation head 19 was tilted backward with respect to head surface 20 of global stimulation head 18 . Also, the first electrode 23 of the wide area stimulation head 18 and the first electrode 33 of the narrow area stimulation head 19 are integrated and exposed from the head surfaces 20 and 30 to form an oblong shape elongated vertically. Further, the second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 of the narrow-area stimulation head 19 are integrated, exposed from the head surfaces 20 and 30, and formed into a vertically elongated oval ring shape. A temperature sensor 27 is arranged inside the bent portions of the first electrodes 23 and 33 . In this proposed example, the first electrode 23 of the wide-area stimulation head 18 and the first electrode 33 of the narrow-area stimulation head 19 are integrated. , the number of parts can be reduced, the electrode structure can be simplified, and the cost of the beauty instrument can be reduced accordingly. In addition, 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 integrated, the number of parts can be reduced compared to the case where the electrodes 24 and 34 are separately provided. Therefore, the electrode structure can be simplified, and the cost of beauty instruments can be reduced accordingly.

Also in Proposed Example 6, the same control as in Proposed Example 1 is performed. That is, the control unit 48 constantly monitors the detection signal output from the current value detection unit 50, and as shown in FIG. , among the skin electrodes 22 and 32, it is determined that the skin electrode 22 of the wide area stimulation head 18 is in contact with the skin surface, and the output value of the high-frequency current (supplied power) supplied to the skin electrode 22 is Increase the standard output value or more than the standard output value. Conversely, when the detection signal of the current value detection unit 50 is smaller than the threshold, it is determined that the skin electrode 32 of the narrow-area stimulation head 19 is in contact with the skin surface among the skin electrodes 22 and 32. The output value of the high-frequency current (supplied power) supplied to the skin electrode 32 is reduced below the reference output value. This is because the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, so that when the same high-frequency current as that used when the skin electrode 22 of the wide-area stimulation head 18 is applied to the skin surface is supplied to the skin electrode 32, the electrodes 33 and 34 The power that is converted to heat in between can be large, and the skin can be heated unnecessarily. In order to solve such a problem, the control unit 48 detects from the current value of the current value detection unit 50 that the skin electrode 32 of the narrow-area stimulation head 19 is applied to the skin, as described above. The high frequency current supplied to the skin electrode 32 is made smaller than the high frequency current supplied to the skin electrode 22 . note that. In Proposal Example 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 stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide stimulation head 18. be. Therefore, the temperature of the skin electrodes 32 of the narrow stimulation head 19, which has a small heat radiation area, tends to rise. However, in the case of this proposed example, since the first electrodes 23 and 33 and the second electrodes 24 and 34 are integrated and connected, the temperature rise of the skin electrode 32 of the narrow area stimulation head 19 is not as much.

(Proposal Example 7) Figs. 16 and 17 show a proposal example 7 of the beauty instrument. In the beauty device of Proposal 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 formed in a droplet-like continuous state in the head case 17, and each skin contact body 22, 32, PTC heaters 53 and 54 serving as heat sources and temperature sensors 27 and 37 adjacent thereto are arranged. Although not shown, each stimulation head 18 and 19 is provided with a skin contact sensor, and by driving the PTC heater 53 (or 54) on the side to which the detection signal of the skin contact sensor is output, the skin surface is stimulated. It was made possible to apply thermal stimulation to. In this proposed example, the metal skin electrodes 22 and 23 are not provided, and the case surfaces of the wide area stimulation head 18 and the narrow area stimulation head 19 made of plastic material constitute the skin contact bodies 22 and 32. bottom. Thus, the skin contact members 22 and 32 are not limited to being made of metal, and may be made of plastic material, rubber, or the like. The beauty device according to 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 stimulation in that case is only thermal stimulation. In this way, beauty stimulation may be only thermal stimulation.

(Proposal Example 8) FIG. 18 shows a proposal example 8 of a beauty instrument. In the beauty device of Proposed Example 8, the head surfaces 20 and 30 are formed by vertical flat surfaces orthogonal to the central axis of the base case 16, and a small-area narrow-area stimulation head 19 is provided on the upper portion thereof, and the rest of the area is a wide-area stimulation head. A stimulation head 18 was used. 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 members 22 and 32 were arranged respectively. The skin contacting body 22 of the wide area stimulation head 18 and the skin contacting body 22 of the narrow area stimulation head 19 are flush with each other, but their external shapes and areas are largely different. In the beauty instrument of Proposed Example 1 as well, the head surfaces 20 and 30 can be formed of flat surfaces as in the beauty instrument of the present Proposed Example. The beauty tool of Proposed Example 8 can apply thermal stimulation (cosmetic stimulation) to the skin surface by means of the skin contact members 22 and 32 heated by the Nichrome wire heaters 55 and 56 .

In the beauty device of Proposal Example 9, a wide area stimulation head 18 is provided on the upper front surface of the main body case 1, a narrow area stimulation head 19 is provided on the upper rear surface of the main body case 1, and each of the stimulation heads 18 and 19 has a first A pair of electrodes 23 and 33 and a pair of second electrodes 24 and 34 are provided. Thus, the wide area stimulation head 18 and the narrow area stimulation head 19 may be provided independently at different positions of the main body case 1 .

(Proposal Example 10) Fig. 20 shows a proposal example 10 of a beauty instrument. In the beauty tool of proposed example 10, a changeover switch 57 is provided between the high-frequency output unit 49 and the first electrodes 23, 33, and the electrodes 23, 23 are provided between the first electrode 23 and the second electrode 24 of the skin electrode 22. 24 is provided with a current confirmation unit 58 for detecting that the drive current is supplied. In this beauty instrument, even though the driving current is supplied between the electrodes 23 and 24 of the wide-area stimulation head 18, the detection signal is not output from the current confirmation unit 58, or the detection signal value is below the threshold. Then, the controller 48 determines that the beauty tool is not in use, switches the selector switch 57, and supplies the drive current to the skin electrode 34 side of the narrow area stimulation head 19 side.

(Proposal Example 11) Fig. 21 shows a proposal example 11 of a beauty instrument. In the beauty tool of Proposed Example 11, a changeover switch 57 is provided between the high frequency output section 49 and the first electrodes 23 and 33, and an electrode selection switch 59 is provided in the body case 1. FIG. According to this beauty tool, when the user operates the electrode selection switch 59, the control unit 48 operates the switching switch 57 to activate the skin electrode 22 (or skin electrode 32) on the side specified by the user. Let

(Example 1) Fig. 22 shows Example 1 of the beauty instrument according to the present invention. In the beauty instrument of Example 1, the first electrode 23 of the wide area stimulation head 18 and the first electrode 33 on the side of the narrow area stimulation head 19 are integrally formed, and the second electrode 24 of the wide area stimulation head 18 and the narrow area stimulation head 18 are integrally formed. The second electrode 34 on the head 19 side is integrally formed, and the former electrodes 23, 33 and the latter electrodes 24, 34 are arranged in a state adjacent to the head surfaces 20, 30 on the left and right. Further, the surface area of the former electrodes 23 and 33 is set 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 outline surrounding 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, and does not include the area of the peripheral side surface bulging from the head surface 20, 30.
The temperature sensors 27/37 are arranged inside the second electrodes 24/34. As shown in FIG. 22, the skin electrodes 32 on the side of the narrow-area stimulation head 19 are tilted backward with respect to the skin electrodes 22 on the side of the wide-area stimulation head 18 . As described above, the basic structure of the beauty device of Example 1 is the same as that of the beauty device of Proposed Example 1, except for the shape and arrangement of the electrodes.

In the beauty tool according to Example 1, a high frequency current is supplied between the first electrode 23 of the wide area stimulation head 18 and the second electrode 24 of the wide area stimulation head 18 to heat the skin surface from the inside. Similarly, a high-frequency current is supplied between the first electrode 33 of the narrow-area stimulation head 19 and the second electrode 34 of the narrow-area stimulation head 19 to heat the skin surface 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 in a curved continuous plane, the electrode surface ( The skin contact surface) has a V-shaped cross section. 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 in a curved continuous plane, the electrodes of the second electrodes 24 and 34 of the stimulation heads 18 and 19 The surface (skin contact surface) has a V-shaped cross section. The electrode surfaces of the first electrodes 23 and 33 and the second electrodes 24 and 34 do not need to be flat surfaces, and may be curved surfaces protruding from the outside. Alternatively, the first electrode 23 and the second electrode 24 of the wide area stimulation head 18 may be formed with a flat surface, and the first electrode 33 and the second electrode 34 of the narrow area stimulation head 19 may be formed with an outwardly projecting curved surface. good. Furthermore, the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 are formed with outwardly projecting curved surfaces, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 are connected to the respective electrodes 23 and 24 . It may be formed with a curved surface having a larger curvature than the curved surface of 24 . According to the beauty instrument in which at least the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 are formed with outwardly projecting curved surfaces, when cosmetic treatment is performed with the narrow-area stimulation head 19, the area around the nose, etc. It is possible to accurately perform cosmetic treatment on a skin part having depressions. Furthermore, at least one side of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 can be formed with an outwardly projecting curved surface. According to this, it is possible to more accurately treat a skin portion having a dent. In this embodiment, the skin electrode 22 and the skin electrode 32 are formed by providing one bent portion in the first electrodes 23 and 33 and the second electrodes 24 and 34, but two bent portions are provided and one more is formed. A skin electrode can be constructed with a surface area less than . Also, in this embodiment, as shown in FIG. 22, the positions of the bent portions on the left and right are the same, but they may be shifted slightly in the vertical direction. Further, the outwardly projecting curved surfaces of the first electrode 23 and the second electrode 24 of the wide area stimulation head 18 may be composed of a compound R having different curvatures in the middle. The outwardly projecting curved surfaces of the first electrode 33 and the second electrode 34 may also be composed of a compound R having different curvatures in the middle. In particular, for the curved surfaces of the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19, the curvature on the side of the bending portion is set small, and the curvature on the side of the bending portion is set to be small from the middle to the end away from the bending portion. If the curvature is larger than the curvature of , it is possible to accurately treat skin areas with depressions. Furthermore, the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 have an inwardly concave curved surface on the side of the bent portion, and an outwardly protruding curved surface from the middle away from the bent portion. It can be configured to be continuously connected to the concave curved surface. According to this, a skin part can be thermally stimulated at a point. The corresponding surfaces of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be flat surfaces or curved surfaces that protrude outward. According to such a beauty instrument, when performing beauty treatment with the narrow-area stimulation head 19, it is possible to accurately perform beauty treatment on a skin region with depressions such as around the nose.

Also in Example 1, the same control as Proposed Example 1 is performed. That is, the control unit 48 constantly monitors the detection signal output from the current value detection unit 50, and as shown in FIG. , among the skin electrodes 22 and 32, the electrode surface (skin contact surface) of the skin electrode 22 of the wide area stimulation head 18 is judged to be in contact with the skin surface, and the high-frequency current supplied to the skin electrode 22 Increase the output value of (supplied power) to the standard output value or more than the standard output value. Conversely, when the detection signal of the current value detection unit 50 is smaller than the threshold, the electrode surface (skin contact surface) of the skin electrode 32 of the narrow area stimulation head 19 among the skin electrodes 22 and 32 is in contact with the skin surface. Then, the output value of the high-frequency current (supplied power) supplied to the skin electrode 32 is reduced from the reference output value. This is because the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, so that when the same high-frequency current as that used when the skin electrode 22 of the wide-area stimulation head 18 is applied to the skin surface is supplied to the skin electrode 32, the electrodes 33 and 34 The power that is converted to heat in between can be large, and the skin can be heated unnecessarily. In order to solve such a problem, the control unit 48 detects from the current value of the current value detection unit 50 that the skin electrode 32 of the narrow-area stimulation head 19 is applied to the skin, as described above. The high frequency current supplied to the skin electrode 32 is made smaller than the high frequency current supplied to the skin electrode 22 . note that. In Proposal Example 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 stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide stimulation head 18. be. Therefore, the temperature of the skin electrodes 32 of the narrow stimulation head 19, which has a small heat radiation area, tends to rise. However, in the case of this embodiment, since the first electrodes 23 and 33 and the second electrodes 24 and 34 are integrated and connected, the temperature rise of the skin electrode 32 of the narrow area stimulation head 19 is not as much.

In Example 1, the threshold value (operating temperature) of the temperature sensor 27 is set at 45°C, and the threshold value (operating temperature) of the temperature sensor 37 is set at 43°C, as in Proposal Example 1. That is, the threshold of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set smaller than the threshold of the detection signal of the temperature sensor 27 provided in the wide-area stimulation head 18 . In this way, when the threshold value of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set to be small, when the high-frequency current is supplied to the skin electrodes 32 of the narrow-area stimulation head 19, the skin electrodes 32 are contacted. It can prevent the temperature of the skin you are wearing from becoming a high temperature.

The beauty instrument according to Example 1 can be implemented in the following modes.
The wide-area stimulation head 18 and the narrow-area stimulation head 19 are provided with first electrodes 23 and 33 and second electrodes 24 and 34 that constitute skin contact bodies 22 and 32, respectively.
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 each integrated into a long area. It is formed in the shape of an axis,
The first electrodes 23 and 33 and the second electrodes 24 and 34 are arranged side by side with a predetermined interval,
The sum of the surface areas of the first electrode 23 and the second electrode 24 constituting the skin contact body 22 of the wide area stimulation head 18 is the first electrode 33 and the second electrode 34 constituting the skin contact body 32 of the narrow area stimulation head 19. is set larger than the total surface area of
According to the beauty appliance according to the first embodiment, by using the wide-area stimulation head 18, it is possible to suitably carry out cosmetic treatment on flat and large-area skin surfaces such as cheeks and foreheads. It can be used to accurately perform cosmetic treatment on narrow skin areas such as around the nose and around the eyes.

In the beauty instrument according to 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 formed in a curved continuous plane. Further, 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 in a curved continuous plane. According to such a thermal head, compared with the case where the first electrodes 23, 33 and the second electrodes 24, 34 are separately provided in each stimulation head 18, 19, the number of parts can be reduced and the electrode structure can be simplified. The cost of beauty instruments can be reduced by the amount. Furthermore, since the skin contact surface of the skin electrode 32 of the narrow stimulation head 19 is slanted with respect to the skin contact surface of the skin electrode 22 of the wide stimulation head 18, when using one stimulation head 18 (or 19), The other stimulation head 19 (or 18) can be prevented from coming into contact with the skin surface, and the beauty treatment by each stimulation head 18/91 can be performed accurately.

In the beauty instrument according to Example 1, the temperature sensor 27 is provided inside at least one of 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 24 of the narrow area stimulation head 19 are provided. A temperature sensor 37 is provided inside at least one of the two electrodes 34 . In addition, the threshold value of the temperature sensor 37 provided in the narrow-area stimulation head 19 was set lower than the threshold value of the temperature sensor 27 provided in the wide-area stimulation head 18 . According to such a thermal head, when high-frequency current is supplied to the skin electrodes 32 of the narrow-area stimulation head 19, the threshold value of the temperature sensor 37 is set low, so the temperature of the skin in contact with the skin electrodes 32 is high. You can prevent it from getting hot.
When the skin electrodes 32 of the narrow-area stimulation head 19 are applied to the skin, the high-frequency current supplied to the skin electrodes 32 is less than the high-frequency current supplied to the skin electrodes 22 . According to such a thermal head, since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, when the same high-frequency current as that used when the skin electrode 22 of the wide-area stimulation head 18 is applied to the skin surface is supplied to the skin electrode 32, each electrode Electric power converted into heat between 33 and 34 may become large and the skin may be heated unnecessarily, but this can be prevented.

(Proposal Example 12) FIG. 23 shows a proposal example 12 of the beauty instrument. In the beauty instrument of Proposed Example 12, a wide area stimulation head 18 is provided near the upper part of the main body case 1, and a narrow area stimulation head 19 is provided at the upper end of the main body case 1. Then, the first electrode 23 of the wide area stimulation head 18 and the The two electrodes 24 and the first electrode 33 and the second electrode 34 of the narrow area stimulation head 19 were each composed of rotatable rollers. Specifically, two first electrodes 23 and two second electrodes 24 of the wide-area stimulation head 18 are alternately arranged, three insulating rollers 61 are arranged between the electrodes 23 and 24, and these are attached to the body case 1. It was rotatably supported by a roller shaft 62 fixed to. Similarly, the first electrode 33, insulating roller 63, and second electrode 34 of the narrow-area stimulation head 19 were arranged in the order described, and were rotatably supported by a roller shaft 64 fixed to the body case 1. The width and diameter of the first electrode 23 and the second electrode 24 on the side of the skin electrode 22 are set to be the same as the width and diameter of the first electrode 33 and the second electrode 34 on the side of the skin electrode 32, and the electrode parts are shared. In addition, the skin electrode 22 is composed of two first electrodes 23 and two second electrodes 24, and the contact area of the skin electrode 22 with the skin is the same as the contact area of the skin electrode 32 with the skin. made bigger. In this way, the following forms can be adopted for making the contact areas of the skin electrodes 22 and 23 with respect to the skin different. The width dimensions of the first electrode 23 and the second electrode 24 on the skin electrode 22 side, and the width dimensions of the first electrode 33 and the second electrode 34 on the skin electrode 32 side are the same. The diameter of the two electrodes 24 is 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 with the skin differ between the skin electrodes 22 and 32 . The diameters of the electrodes 23, 24, 33, and 34 are made the same, and the widths of the first electrode 23 and the second electrode 24 on the side of the skin electrode 22 are set to the widths of the first electrode 33 and the second electrode 34 on the side of the skin electrode 32 The contact area of the skin electrodes 22 and 32 with the skin may be varied by setting the width larger than the width of . Moreover, the cross-sectional shape of each electrode 23, 24, 33, 34 may be polygonal. Further, the cross-sectional shape of each electrode 23, 24, 33, 34 may be circular as it is, and a plurality of protrusions or recesses may be provided uniformly on the peripheral surface. This can be expected to have a stimulating effect on the skin.

In this proposed example, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow-area stimulation head 19 are configured to rotate integrally. can be As a result, when the narrow stimulation head 19 is moved on the skin surface, the direction can be changed smoothly. In addition, the two first electrodes 23, the two second electrodes 24, and the three insulating rollers 61 in the wide area stimulation head 18 are also configured to rotate integrally. It can be configured to rotate by rotating. However, considering the quality and cost, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow stimulation head 19 are integrally rotated units, while the wide stimulation head 18 has two second electrodes. Regarding the one electrode 23, the two second electrodes 24, and the three insulating rollers 61, the left first electrode 23, the second electrode 24, and the insulating roller 61 are integrally rotatable units, and the right first electrode 23 , the second electrode 24 and the insulating roller 61 are integrally rotatable as a unit that can rotate left and right independently. The central insulating roller 61 may be configured to rotate integrally with either the left or right unit, or may be configured to rotate independently.

In this proposed example, the narrow-area stimulation head 19 is fixed, but as a modification, the narrow-area stimulation head 19 can be provided so as to be vertically extendable with respect to the main body case 1 . In this case, the first electrode 33 , the insulating roller 63 and the second electrode 34 are extended and contracted with respect to the main body case 1 together with the roller shaft 62 . The portion of the roller shaft 62 located inside the main body case 1 is provided with a detent structure (protruding portion), and by engaging with the corresponding detent structure (three recessed portions) in the main body case 1, the roller shaft 62 can be moved to a low position or an intermediate position. Positioning can be performed at three positions: position and high position. With this stretchable 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 get in the way when the narrow-area stimulation head 19 is used, improving usability. Also, the narrow-area stimulation head 19 can be configured to be completely housed in the main body case 1 . In this case, there are four modes. This configuration allows protection of the narrow area stimulation head 19 . Although the wide-area stimulation head 18 is also fixed in this proposed example, it can be provided so as to be extendable in the same manner as the narrow-area stimulation head 19 described above. The stretching direction in this case is the front-rear direction.

In addition, although the narrow-area stimulation head 19 is fixed in this proposed example, as a modification, the narrow-area stimulation head 19 may be configured to be elastically biased in the vertical direction with respect to the main body case 1 . In this case, the first electrode 33 , the insulating roller 63 and the second electrode 34 are elastically biased against the main body case 1 together with the roller shaft 62 . Specifically, two coil springs (springs) are provided inside the main body case 1, and the springs are inserted into the left and right ends of the roller shaft 62, and the springs are separately attached to the left and right ends of the roller shaft 62. The narrow stimulation head 19 is elastically biased upward by being pressed against the two fixed abutment pieces. The two abutment pieces abut on the inner wall surrounding the opening of the main body case 1 into which the roller shaft 62 is loosely fitted, thereby restricting upward movement. This restricts the upward movement of the entire narrow-area stimulation head 19 . When the narrow-area stimulation head 19 is pressed against the skin, the pressing force causes the narrow-area stimulation head 19 to sink into the main body case 1, so that it can follow the unevenness of the skin and reduce the burden on the skin. . The wide area stimulation head 18 is also fixed in this embodiment, but can be configured to be elastically biased in the same manner as the narrow area stimulation head 19 described above. In this case, the elastic biasing direction is not the vertical direction but the front-rear direction. In addition, in the above configuration, a vibrator having a configuration in which a motor and an eccentric cam are attached to the motor shaft can be provided inside the narrow-area stimulation head 19 and/or the wide-area stimulation head 18 . As a result, if the vibrator is operated during thermal stimulation, the narrow stimulation head 19 and/or the wide stimulation head 18 can be vibrated in the direction in which they are elastically biased, and the skin is stimulated by small vibrations. be able to.

In the proposed example, the wide area stimulation head 18 has the two first electrodes 23 and the two second electrodes 24 with the same diameter. The diameter of the second electrode 24 on the right end remains the same, and the diameters of the second electrode 24 and the first electrode 23 on the inner side (near the center) are made one turn larger than the diameters of the first electrode 23 on the left end and the second electrode 24 on the right end. It can be of increased size. As a result, all the electrodes can be easily brought into contact with the skin surface of the recessed portion (for example, under the chin), and appropriate thermal stimulation can be applied to the skin.

In addition, in the proposed example, the narrow area stimulation head 19 and the wide area stimulation head 18 are passive in that the electrodes 23, 24, 33, and 34 are configured by rollers, and are rotated by pressing and moving them against the skin. Although it has a rotating structure, it can be configured to actively rotate by providing power such as a motor.

In this proposed example, the narrow stimulation head 19 is provided on the upper surface wall of the main body case 1, and the wide stimulation head 18 is provided on the front wall of the main body case 1, but the narrow stimulation head 19 is provided on the rear wall of the main body case 1. can be set to

Also, for example, a rectangular frame is rotatably attached to the roller shaft 64, the narrow stimulation head 19 is rotated on one side of the upper side of the frame, and the wide stimulation head 18 is rotated on one side of the opposite lower side. can be set as possible. The portion of the frame attached to the roller shaft 64 is the central portion of the left and right sides of the frame. As a result, the narrow stimulation head 19 or the wide stimulation head 18 can be used alternatively by rotating the frame. Therefore, it is possible to improve usability without misuse.
The basic structure of the beauty instrument of Proposed Example 12 is the same as that of the beauty instrument of Proposed Example 1 except for the shape and arrangement of the electrodes.

(Action and effect of the beauty device explained in each proposal example)

It is possible to accurately perform beauty treatment on narrow skin areas such as the eyes. Therefore, it is possible to provide a beauty tool that can evenly perform beauty treatment on the entire facial skin. Also, since the stimulation heads 18 and 19 are provided with dedicated skin contact bodies 22 and 32, the heating of the skin and the application of electrical stimulation to the skin can be reliably performed.

The electrode surface of the skin electrode 32 of the narrow area stimulation head 19 is inclined with respect to the electrode surface of the skin contact body 22 of the wide area stimulation head 18 . According to such a beauty device, when one stimulation head 18 (or 19) is used, the other stimulation head 19 (or 18) does not come into contact with the skin surface. can be performed accurately.

The head surface 30 supporting the skin contact body 32 of the narrow stimulation head 19 is inclined with respect to the head surface 20 supporting the skin contact body 22 of the wide stimulation head 18. - 特許庁According to such a beauty device, in addition to the difference in the area of each stimulation head 18, 19, the wide stimulation head 18 and the narrow stimulation head 19 can be distinguished by the difference in inclination, and the narrow stimulation head 19 is particularly used. It is possible to allow the user to intuitively recognize the target site of the cosmetic treatment. Therefore, each stimulation head 18, 19 can be well prevented from being used incorrectly.

A wide area stimulation head 18 and a narrow area stimulation head 19 are provided with temperature sensors 27 and 37 for detecting skin temperature. According to such a beauty instrument, the temperature state of the skin contacting bodies 22, 32 of the stimulation heads 18, 19 can be accurately detected, so that the skin temperature can be reliably prevented from becoming higher than necessary, and beauty treatment can be performed safely. can do

Either one of the temperature sensor 27 provided in the wide area stimulation head 18 and the temperature sensor 37 provided in the narrow area stimulation head 19 is designed to serve also as an environmental temperature sensor for the environment in which the beauty instrument is used. According to such a beauty device, for example, when performing cosmetic treatment using the wide area stimulation head 18, the environmental temperature is detected by the temperature sensor 37 provided in the narrow area stimulation head 19, and the difference in seasons and indoor temperature is detected. The operating state of the global stimulation head 18 can be adjusted depending on the. For example, in summer when the environmental temperature is high, the drive current supplied to the skin contact member 22 is adjusted higher than the reference output value, and in winter the drive current supplied to the skin contact member 22 is adjusted lower than the reference output value. Control such as adjustment can be performed. Further, in the case of the thermal head 2 in which a thermal heat source such as a PTC heater is provided inside the skin contact member 22, the driving wave current supplied to the thermal heat source can be adjusted to cope with the difference in environmental temperature. can.

A high-frequency voltage is applied to the skin contact members 22 and 32, and the skin is heated by the heat generating action of the high-frequency current flowing through the skin. According to such a beauty device, the skin can be heated from the inside by the heat generating action of the high-frequency current flowing through the skin. The skin can be heated quickly and efficiently as compared with the case of heating .

The skin contact bodies 22 and 32 of the stimulation heads 18 and 19 are composed of the first electrodes 23 and 33 and the second electrodes 24 and 34, and the supply state of the high frequency current supplied to the skin contact bodies 22 and 32 is The control unit 48 makes adjustments according to the threshold values of the detection signals of the temperature sensors 27 and 37 . In addition, the threshold of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set to be smaller than the threshold of the detection signal of the temperature sensor 27 provided in the wide-area stimulation head 18 . Thus, when the threshold value of the detection signal of the temperature sensor 37 of the narrow-area stimulation head 19 is set small, the temperature control of the narrow-area stimulation head 19 can be controlled from a low temperature stage compared to the wide-area stimulation head 18. Therefore, it is possible to prevent the narrow stimulation head 19 from falling into a high temperature state.

A shared electrode 36 is formed by integrating a second electrode 24 on the side of the wide-area stimulation head 18 and a second electrode 34 on the side of the narrow-area stimulation head 19 at adjacent portions of the wide-area stimulation head 18 and the narrow-area stimulation head 19. bottom.

Cost can be reduced. In addition, the projection height of the electrodes 23 and 24 in the wide area stimulation head 18 from the head surface 20 is set equal to or larger than the projection height from the head surface 20 of the second electrode 24 constituting the shared electrode 36. . Furthermore, the projection height of the electrodes 33 and 34 in the narrow-area stimulation head 19 from the head surface 30 is smaller than the projection height from the head surface 20 of the second electrode 24 on the wide-area stimulation head 18 side constituting the common electrode 36. set. According to such a beauty device, the plane connecting the first electrode 33 of the narrow-area stimulation head 19 and the second electrode 34 constituting the common electrode 36 (the plane in contact with the skin) is the first electrode 23 of the wide-area stimulation head 18. It can intersect the plane connecting the second electrodes 24 constituting the shared electrode 36 (the plane in contact with the skin). Therefore, for example, when performing cosmetic treatment using the narrow-area stimulation head 19, the electrodes 23 and 24 of the wide-area stimulation head 18 can be well prevented from coming into contact with the skin surface.

The head surface 30 of the narrow-area stimulation head 19 was set so as to gradually lower from the adjacent portion of the second electrodes 24 and 34 constituting the shared electrode 36 to the head end of the narrow-area stimulation head 19 . According to such a beauty device, the posture of the thermal head 2 in close contact with the skin differs greatly between when the wide-area stimulation head 18 is used and when the narrow-area stimulation head 19 is used, so the narrow-area stimulation head 19 is used. It is possible to more reliably prevent the electrodes 23 and 24 of the wide area stimulation head 18 from coming into contact with the skin surface when cosmetic treatment is performed.

When the head surface 30 on the side of the narrow-area stimulation head 19 is tilted backward with respect to the head surface 20 on the side of the wide-area stimulation head 18, the posture of the beauty device when the stimulation heads 18, 19 come into contact with the skin surface is changed.

The skin contact body 22 of the wide area stimulation head 18 and/or the skin contact body 32 of the narrow area stimulation head 19 are designed to serve also as skin contact sensors. Furthermore, when the skin contact bodies 22 and 32 of the stimulation heads 18 and 19 come into contact with the skin surface, the controller 48 controls the skin contact bodies 22 and 32 based on detection signals output from the skin contact bodies 22 and 32. The supplied high-frequency current is adjusted, or the threshold value of the detection signal of the temperature sensor 27 is adjusted. According to such a beauty device, the skin contact bodies 22 and 32 of the stimulation heads 18 and 19 can be used to detect that the skin contact bodies 22 and 32 are in contact with the skin surface.
