According to such a beauty device, the temperature state of the skin contacting bodies 22 and 32 in each stimulation head 18 and 19 can be accurately detected, thereby reliably preventing the skin temperature from becoming higher than necessary and safely performing beauty treatment. It can be carried out.

Either one of the temperature sensor 27 provided on the wide-area stimulation head 18 and the temperature sensor 37 provided on the narrow-area stimulation head 19 serves 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 beauty treatment using the wide-area stimulation head 18, the temperature sensor 37 provided in the narrow-area stimulation head 19 detects the environmental temperature, and detects differences in seasons and indoor temperatures. The operating state of the wide-area stimulation head 18 can be adjusted accordingly. For example, in the summer when the environmental temperature is high, the driving wave current supplied to the skin contacting body 22 is adjusted to be higher than the standard output value, and in the winter, the driving current supplied to the skin contacting body 22 is adjusted to be lower than the standard output value. Controls such as adjustment can be performed.

When performing beauty treatment, each electrode 23 and 2 of the wide area stimulation head 18
4 can be further reliably prevented from coming into contact with the skin surface.

When the head surface 30 on the narrow-area stimulation head 19 side is tilted backward relative to the head surface 20 on the wide-area stimulation head 18 side, the posture of the beauty instrument when each stimulation head 18, 19 contacts the skin surface is further improved.

In such a beauty appliance, the control section 48 can detect the environmental temperature of the user's usage environment from the temperature detected by the temperature sensor 27 immediately after the power button section 5 is turned on. The drive current supplied to 22 and 32 can be adjusted.

The wide area stimulation head 18 and the narrow area stimulation head 19 are provided with skin contact sensors for detecting that the skin contact bodies 22 and 32 are in contact with the skin surface. According to these beauty tools,
Depending on the presence or absence of the detection signal of the skin contact sensor, the drive current supplied to the skin contact body 22, 32 is adjusted, or the threshold value of the detection signal of the temperature sensor 27, 37 is adjusted, and the skin contact body 22
- The drive current supplied to the drive circuit 32 can be optimized and wasteful power consumption can be reduced.

The threshold value of the detection signal of the sensor 27 is adjusted. According to such a beauty device, it is possible to detect that the skin contacting bodies 22 and 32 are in contact with the skin surface by using the skin contacting bodies 22 and 32 of each stimulation head 18 and 19, so a skin contact sensor is separately provided. Compared to the case where the heating head 2 is provided, the number of parts can be reduced and the structure of the heating head 2 can be simplified, and the cost of the beauty instrument can be reduced accordingly.

It includes a skin electrode (skin contact body) 32 that heats the skin surface. The head surface 30 is a curved surface that slightly bulges diagonally upward, and the entire head surface 30 is the same as the head surface 20 of the wide-area stimulation head 18.
leaning backwards against In FIG. 1, the portion above the boundary line b between both head surfaces 20 and 30 becomes the narrow area stimulation head 19. In this embodiment, the head surface 30 of the narrow-area stimulation head 19 is tilted backward by about 45 degrees with respect to the head surface 20 of the wide-area stimulation head 18 (see FIG. 4).

The electrode stand 31 consists of a slightly curved curved surface that is substantially parallel to the head surface 30 . Skin electrode 32
is composed of a first electrode 33 having a semicircular shape that protrudes upward, which is arranged on the upper half side of the electrode stand 31, and a second electrode 34, which has a semicircular shape that protrudes downward, which is arranged below the first electrode 33. These electrodes 33 and 34 are
It is provided so as to be embedded in the holder frame 35 formed in a bulge on the electrode stand 31, and its surface is exposed so as to be flush with the holder frame 35. The second electrode 34 is provided integrally with the second electrode 24 on the upper part of the wide-area stimulation head 18 to constitute a common electrode 36 . A temperature sensor 37 such as a thermistor is provided inside the first electrode 33 to detect skin temperature. The first electrode 33 and the second electrode 34 are made of, for example, a titanium plate material. Note that the second electrode 24, the first electrode 33, and the second electrode 34 do not need to be buried in the holder frames 25, 35, and the first electrode 2

(cooling head)
In FIG. 3, the cooling head 3 includes a Peltier element 40, a cooling head 41 disposed on the rear surface of the Peltier element 40 to transmit cold heat to the skin surface, and a heat sink 42 disposed on the front surface of the Peltier element 40 for discharging warm heat. configured. The cooling/thermal head 41 is made of an aluminum die-cast molded product, and its heat transfer surface 43 is exposed outside the mounting window of the rear case 1b.
The heat sink 42 is made of an aluminum die-cast molded product, and radiates the heat of the Peltier element 40 through a group of radiation fins. Although not shown, the rear case 1b has a discharge window for discharging heat to the outside of the case. Acceleration sensors 45 are provided at the top and bottom of the interior of the main body case 1 to detect whether the beauty instrument is in use.

(control unit)
As shown in FIGS. 5 and 6, the beauty instrument is provided with a control section 48 that controls the operating states of the heating head 2 and the cooling head 3. As shown in FIGS. When the power button unit 5 is turned on, the thermal operation mode is started, and the control unit 48 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 via the high-frequency output unit 49. is applied, and the mode display section 8 on the heating operation mode side lights up. Also, when the level switching button section 7 is turned on, the control section 48
The high-frequency voltage applied to the skin electrodes 22, 32 is cyclically switched in the order of weak, medium, and strong, and the selected high-frequency voltage is applied to the skin electrodes 22, 32. At the same time, the lighting state of the level display section 9 is made to correspond to the level switching state.

When the beauty device is ready as described above, for example, the skin electrode 22 of the wide area stimulation head 18
When applied to facial skin such as the cheeks and forehead that has been applied with emulsion or lotion, and slid along the facial skin, the acceleration sensor 45 detects the movement, so the control unit 48 controls the pair of electrodes 23 and 24. A high frequency current is supplied between the two. Specifically, a high frequency voltage of a sine wave with a frequency of 1 MHz is applied to the first
The voltage is applied between the 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 beauty stimulation in this case is both thermal stimulation and electrical stimulation. The control unit 48 can recognize that the beauty device is being used based on the detection signal output from the acceleration sensor 45. Further, 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 cannot recognize that the narrow-area stimulation head 19 is applied to the skin based on the detection signal from the current value detection unit 50. can. Acceleration sensor 45 can be omitted. In that case, if you turn on the power button section 5,
The control unit 48 starts the timer, and the skin electrode 22 of the wide area stimulation head 18 and the narrow area stimulation head 1
After applying a high frequency voltage to the skin electrode 32 of No. 9, the power is turned off when a predetermined time has elapsed.

If the detection signal from one of the two acceleration sensors 45 is not output for a certain period of time, there is a possibility that the thermal head 2 is not moving while being applied to the facial skin, so the controller 48 reduces or stops the supply of high frequency current to the skin electrodes 22 and 32. Further, the control unit 48 constantly monitors the detection signal output from the current value detection unit 50, and as shown in FIG. Of 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 (supply power) supplied to the skin electrode 22 is determined. Set to the standard output value or increase it above the standard output value. Furthermore, both acceleration sensors 45
If no detection signal is output from the beauty device, it is determined that the beauty instrument is not operating, and the supply of high-frequency current is reduced or stopped. Conversely, if the detection signal from the current value detection unit 50 is smaller than the threshold, it is determined which of the skin electrodes 22 and 32 is in contact with the skin electrode 32 of the narrow area stimulation head 19, and The output value of the high frequency current (supplied power) supplied to the electrode 32 is reduced from the reference output value. This is because the area and heat capacity of the skin electrode 32 of the narrow-area stimulation head 19 are small, and the heat dissipation area is small, so the temperature easily rises, and a high-frequency current equivalent to that of the skin electrode 22 of the wide-area stimulation head 18 is supplied to the skin electrode 32. Then, the degree of increase in skin temperature caused by the skin electrode 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 described later, there is a risk of a temporary overshoot state. It is. In this way, in the control by the control unit 48 of this 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 value of the current flowing in the skin between the first electrode 23 and the second electrode 24 in the narrow area stimulation head 19 are
Based on the current value flowing through the skin between the head 18 and the second electrode 34, it is possible to detect whether either the wide-area stimulation head 18 or the narrow-area stimulation head 19 is in contact with the skin. Then, 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 9. Conversely, when the control unit 48 detects that the wide-area stimulation head 18 is in contact with the skin, it supplies the wide-area stimulation head 18 with power that is higher than the power supplied to the narrow-area stimulation head 19. supply That is, when either the wide-area stimulation head 18 or the narrow-area stimulation head 19 comes into contact with the skin, the high-frequency output section 49 can automatically supply electric power corresponding to these heads. Therefore, it is possible to save the effort of manually switching the power supply. Also, since you don't forget to switch, you can reliably prevent unnecessary increases in skin temperature. The current value detection section 50 and the skin electrodes 22 and 32 constitute a skin contact detection section. In this embodiment, the skin electrode 2
Although the electrodes 2 and 32 also serve as skin contact sensors, a dedicated sensor such as a capacitance type contact sensor may be provided separately from the skin electrodes 22 and 32.

If the detection signal of either the temperature sensor 27 or 37 exceeds the threshold while using the wide area stimulation head 18 or the narrow area stimulation head 19, the control unit 48 supplies the signal to the skin electrode 22 or 32. The supply state of the high frequency current (supplied power) is reduced to prevent skin temperature from increasing. When the detection signal becomes below the threshold value, the high frequency current supply state is returned to the original state, and when the detection signal exceeds the threshold value again, the high frequency current supply state is reduced. By repeating this, the skin temperature becomes constant. In this embodiment, the threshold value (operating temperature) of the temperature sensor 27 is set to 45°C, and the threshold value (operating temperature) of the temperature sensor 37 is set to 43°C. That is, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow area stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide area stimulation head 18. In this way, the reason why the threshold values of the detection signals of the temperature sensors 27 and 37 in each stimulation head 18 and 19 are made different is because the area and heat capacity of the skin electrode 32 of the narrow area stimulation head 19 are small, and the heat dissipation area is small. If the skin electrode 32 is supplied with a high-frequency current equivalent to that of the skin electrode 22 of the wide-area stimulation head 18 because the temperature easily rises, the degree of increase in skin temperature due to the skin electrode 32 is large, so that the temperature of the skin in contact with the skin electrode 32 increases. This is to avoid the risk of the temperature becoming too high. In other words, when high-frequency current is supplied to the skin electrode 32 of the narrow-area stimulation head 19, the threshold value of the temperature sensor 37 is set low, so even if overshoot occurs, it is possible to prevent the skin temperature from becoming high.

As described above, the threshold values of the temperature sensors 27 and 37 are made different to prevent the skin temperature from rising. Although it is sufficient to have at least one of the configurations for varying the supply state of high-frequency current to the skin electrodes 32, in this embodiment, 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 supply state of high-frequency current, the amount of applied high-frequency voltage or the amount of high-frequency current supplied is significantly reduced, and the balance between heating and heat radiation is adjusted. It can be set to prevent skin temperature from rising more than necessary without temperature control using a sensor. In addition, the control unit 48 can recognize the environmental temperature of the user's usage environment using the temperature sensor 37 of the narrow area stimulation head 19, which is not in use, so that the user's skin can be adjusted in a state corresponding to the environmental temperature. The supply state of the drive current supplied to the electrode 22 can be adjusted. For example, in summer, the drive current supplied to the skin electrode 22 is adjusted to be higher than the standard output value, as shown by the upward white arrow in FIG. 7, and in winter, as shown by the downward white arrow in FIG. Thus, the drive current supplied to the skin electrode 22 is adjusted to be lower than the reference output value. In this embodiment, the control unit 48 was made to recognize the environmental temperature of the user's usage environment using the temperature sensor 37 of the narrow-area stimulation head 19 that is not in use, but the temperature of the skin electrode 22 on the user's side The sensor 27 can recognize the environmental temperature. In this case, the environmental temperature is detected and recognized immediately after the power button section 5 is turned on, and the supply state of the high-frequency current is adjusted in advance. The sensor 27 is used as a temperature sensor for original temperature control.

Thereafter, when a predetermined period of time has elapsed, the control unit 48 drives a sounding body (not shown) to notify the user that the driving time corresponding to the set driving mode has elapsed. Similarly, by applying the skin electrode 32 of the narrow-area stimulation head 19 to the area around the nose or around the eyes, or by sliding it along the facial skin, the high-frequency current flowing through the skin between the pair of electrodes 33 and 34 stimulates the skin. By heating, beauty treatment can be applied evenly to the entire facial skin.

The area of the skin electrode 32 of the narrow-area stimulation head 19 is considerably smaller than the area of the skin electrode 22 of the wide-area stimulation head 18, and furthermore, the narrow-area stimulation head 19 is tilted significantly backwards with respect to the wide-area stimulation head 18. , beauty treatment of a narrow area using the skin electrode 32 of the narrow area stimulation head 19 can be performed smoothly and accurately. In addition, since the area of the skin electrode 32 of the narrow-area stimulation head 19 is small, the same high-frequency current as when applying the skin electrode 22 of the wide-area stimulation head 18 to the skin surface is applied to the skin electrode 32.
2, the electric power converted into heat between the electrodes 33 and 34 increases, and the degree of rise in skin temperature per unit time increases, so there is a risk that the skin will be heated unnecessarily. In order to solve this problem, the control unit 48 detects that the skin electrode 32 of the narrow-area stimulation head 19 is applied to the skin from the current value of the current value detection unit 50, as described above. The high frequency current supplied to the skin electrode 32 is lower than the high frequency current supplied to the skin electrode 22. Further, the threshold value of the temperature sensor 37 of the narrow area stimulation head 19 is set lower than the threshold value of the temperature sensor 27 of the wide area stimulation head 18 to prevent the skin from being heated unnecessarily.

When the beauty treatment by the wide-area stimulation head 18 and the narrow-area stimulation head 19 is completed, the operation mode is switched from the thermal operation mode to the cooling operation mode by turning on the mode button section 6, and a drive current is supplied to the Peltier element 40. mode indicator light 8 on the cooling/thermal operation mode side.
is lit. After a predetermined period of time has elapsed and the temperature of the heat transfer surface 43 of the cooling head 41 has decreased to the operating temperature, the heat transfer surface 43 is applied to the facial skin to cool it down. When a predetermined period of 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 for the facial skin by the cooling head 41 is finished, and the power button section 5 is pressed to turn off all Turn the driving mode off.

(Example 2) FIG. 8 shows Example 2 of the beauty instrument according to the present invention. The beauty appliance of Example 2 is as follows:
This cosmetic instrument differs from the beauty instrument of the first embodiment in that a temperature sensor 27 is disposed inside the common electrode 36. In this way, if 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 the temperature sensor 27, the manufacturing cost of the beauty appliance can be reduced by omitting the temperature sensor 37. Furthermore, 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 unit 5 is turned on. The drive current supplied to the skin electrode 22 can be adjusted accordingly. In the first embodiment, 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 individually set, but the threshold values of the detection signal can be similarly set individually in this embodiment. In detail, the current detection unit 50 and the skin electrode 2
Based on the detection signal of the skin contact detection unit consisting of 2 and 23, the control unit 48 sets the threshold of the detection signal of the temperature sensor 27 to, for example, 45° C. if the skin electrode 22 of the wide-area stimulation head 18 is in contact with the skin surface. However, if 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, for example, 43°C. That is, the threshold value of the detection signal of the temperature sensor 27 is set smaller when the narrow area stimulation head 19 is used than when the wide area stimulation head 18 is used. Thereby, as with the beauty instrument of Example 1, unnecessary rise in temperature of the skin surface can be prevented. Further, 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, the control unit 48 adapts to the environmental temperature similarly to the beauty instrument of Example 1. Thus, the drive current supplied to the skin electrodes 22 and 23 can be adjusted.

(Example 3) FIG. 9 shows Example 3 of the beauty instrument according to the present invention. In the beauty instrument of Example 3, 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 tilted slightly backward. , which is different from the beauty instrument of Example 1. In this way, the head surface 30 of the narrow-area stimulation head 19 does not need to be tilted significantly backwards, but may be tilted slightly backwards.

(Example 4) Example 4 of the beauty instrument according to the present invention is shown in FIGS. 10 to 12. In the beauty instrument of this fourth embodiment, a wide area stimulation head 18 and a narrow area stimulation head 19 are provided on one head surface 20.
has been established. Specifically, a triangular first electrode 23 is provided at the center of the head surface 20, and around it, three second electrodes 24 forming the skin electrode 22 of the wide area stimulation head 18 and the skin electrode 23 of the narrow area stimulation head 19 are arranged. The three second electrodes 34 constituting the electrode 32 are arranged alternately so that the second electrode 24 can be shared. The second electrode 24 of the wide area stimulation head 18 is arranged parallel to the side of the first electrode 23, and the second electrode 34 of the narrow area stimulation head 19 is arranged parallel to the corner part 2 of the first electrode 23.
It is located facing 3a.

As shown in FIG. 12, among the electrodes 23, 24, and 34, the first electrode 23 has the highest protrusion height h1 from the head surface 20, and the second electrode 24 has the highest protrusion height h2 from the head surface 20. , second
The protrusion height h3 of the electrode 34 from the head surface 20 was set lower in the order of description. In addition, the skin contact surface of the first electrode 23 has a curved surface having a different degree of inclination depending on the difference between the protrusion height h2 of the second electrode 24 and the protrusion height h3 of the second electrode 34. The skin contact surface of 23 is connected to each electrode 24 and 34.
By sloping it downward toward , it is possible to avoid the first electrode 23 on the side of the wide-area stimulation head 18 from coming into contact with the skin, especially when using the narrow-area stimulation head 19 with a small electrode area.

(Example 5) Example 5 of the beauty instrument according to the present invention is shown in FIGS. 13 and 14. In the beauty instrument 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 into a rectangular shape with rounded corners. The head surface 30 of the area stimulation head 19 is tilted backward with respect to the head surface 20 of the wide area stimulation head 18. The wide-area stimulation head 18 is provided with a rectangular first electrode 23 and a second electrode 24 parallel to the left and right sides and the bottom side of the first electrode 23. Further, the narrow-area stimulation head 19 is provided with a laterally elongated first electrode 33 and a laterally elongated 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 each electrode 2
A connecting portion connecting 3 and 33 (see broken line) is arranged inside the heating head 2 in a hidden state. Similarly, the second electrode 24 of the wide area stimulation head 18 and the second electrode 3 of the narrow area stimulation head 19
4, and the connecting portions connecting adjacent second electrodes 24 (see broken lines) and the connecting portions connecting the second electrodes 24 and 34 (see broken lines) are formed inside the heating head 2. It is placed in a hidden manner. Temperature sensors 27, 37 were arranged inside the first electrodes 23, 33.

(Example 6) FIG. 15 shows Example 6 of the beauty instrument according to the present invention. In the beauty 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 into vertically elongated elliptical shapes. Head surface 3 of stimulation head 19
0 was tilted backwards with respect to the head surface 20 of the wide-area stimulation head 18. In addition, wide area stimulation head 1
8 and the first electrode 33 of the narrow area stimulation head 19 are integrated to form the head surface 20.
It was exposed from 30 and formed into an elongated oval shape vertically. Furthermore, the second part of the wide-area stimulation head 18
The electrode 24 and the second electrode 34 of the narrow-area stimulation head 19 were integrated, exposed from the head surfaces 20 and 30, and formed into a vertically long elliptical ring shape. A temperature sensor 27 was placed inside the bent portion of the first electrodes 23 and 33. In this 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 integrated, each electrode 23, 3
Compared to the case where 3 are provided individually, the number of parts can be reduced and 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 is reduced compared to the case where each electrode 24 and 34 is provided separately. The electrode structure can be simplified, and the cost of beauty instruments can be reduced accordingly.

In the sixth embodiment, the same control as in the first embodiment 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. 7, when the detection signal of the current value detection unit 50 is larger than the threshold value (reference current value) 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 increased to the reference output value or above the reference 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, and skin electrode 3
The output value of the high frequency current (supplied power) supplied to 2 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 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, each of the electrodes 33 and 34 There is a risk that the amount of electricity converted into heat between the skin and the skin will increase, causing unnecessary heating of the skin. In order to eliminate these problems, the control unit 48 controls the skin electrode 32 of the narrow area stimulation head 19 as described above.
is applied to the skin from the current value of the current value detection unit 50, and the high frequency current supplied to the skin electrode 32 is reduced compared to the high frequency current supplied to the skin electrode 22. . In addition. In 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 area stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide area stimulation head 18. be. Therefore, the temperature of the skin electrode 32 of the narrow-area stimulation head 19, which has a small heat dissipation area, tends to rise easily. However, in the case of this embodiment, since the first electrodes 23, 33 and the second electrodes 24, 34 are integrated and connected, the temperature rise of the skin electrode 32 of the narrow area stimulation head 19 is different from that in the embodiment 1. Not so much.

(Example 7) FIGS. 16 and 17 show Example 7 of the beauty instrument according to the present invention. In the beauty instrument of Example 7, the skin contact body 22 of the wide area stimulation head 18 and the narrow area stimulation head 1 are installed in the head case 17.

The skin contact body 22 of the wide area stimulation head 18 and the skin contact 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 Example 1 as well, the head surfaces 20 and 30 can be configured with flat surfaces, similarly to the beauty instrument of this embodiment. The beauty instrument of Example 8 uses the skin contacting bodies 22 and 32 heated by the nichrome wire heaters 55 and 56 to
It is possible to provide thermal stimulation (beauty stimulation) to the skin surface.

The second electrode 24 of the wide-area stimulation head 18 and the second electrode 34 on the narrow-area stimulation head 19 side are integrally formed, and the former electrodes 23, 33 and the latter electrodes 24, 34 are connected to the head surface 20.・3
It is now placed adjacent to 0 on the left and right. In addition, the surface area of the former electrodes 23 and 33 is
The surface area of the latter electrodes 24 and 34 is set larger than that of the first electrode 23 and the second electrode 24, which constitute the skin electrode 22 of the wide-area stimulation head 18, and the first electrode 33 and the second electrode 34, which are used for narrow-area stimulation. The skin electrode 32 of the head 19 is configured. A virtual outline surrounding each skin electrode 22, 32 is oval shaped. The surface area of each electrode 23, 24, 33, and 34 is the area of the portion that contacts the skin surface, and does not include the area of the peripheral side surface that bulges out from the head surface 20, 30.
The temperature sensors 27 and 37 were arranged inside the second electrodes 24 and 34. As shown in FIG. 22, the skin electrode 32 on the narrow area stimulation head 19 side is different from the skin electrode 22 on the wide area stimulation head 18 side.
I made it tilt backwards. As described above, the basic structure of the beauty instrument of Example 12 other than the electrode shape and arrangement is the same as the beauty instrument of Example 1.

In the beauty instrument according to the twelfth embodiment, 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 within. 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 of a continuous curved plane, each stimulation head 1
The electrode surfaces (skin contact surfaces) of the first electrodes 23 and 33 of 8 and 19 have a dogleg shape in cross section. Furthermore, 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 a continuous plane that bends, the second electrodes 24 and 34 of each stimulation head 18 and 19 The surface (skin contact surface) has a dogleg shape in cross section. Note that the electrode surfaces of the first electrodes 23, 33 and the second electrodes 24, 34 do not need to be flat surfaces, and may be formed as outwardly protruding curved surfaces. Also,
The first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be formed with flat surfaces, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 may be formed with externally protruding curved surfaces. Furthermore, the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 are formed with externally protruding curved surfaces, and the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19 are formed with the respective electrodes 23 and 24 of the narrow-area stimulation head 19. It may be formed with a curved surface having a larger curvature than the curved surface of 24. At least the first electrode 33 and the second electrode 3 of the narrow area stimulation head 19
According to the beauty instrument in which 4 is formed with an externally protruding curved surface, when beauty treatment is performed using the narrow area stimulation head 19, it is possible to accurately perform beauty treatment on skin areas with depressions such as around the nose. can. 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 externally protruding curved surface. According to this, skin areas with depressions can be treated more accurately. In this embodiment, the skin electrodes 22 and 32 are formed by providing one bent portion in the first electrodes 23 and 33 and the second electrodes 24 and 34, but the skin electrodes 22 and 32 are formed by providing two bent portions and an additional one. A skin electrode can be constructed with a surface area smaller than that of the skin electrode. Further, in this embodiment, as shown in FIG. 22, the positions of the left and right bent portions are the same, but they may be slightly shifted vertically. Further, the externally protruding curved surfaces of the first electrode 23 and the second electrode 24 of the wide-area stimulation head 18 may be configured with a compound R having a different curvature in the middle, and similarly, the narrow-area stimulation head 19 The externally protruding curved surfaces of the first electrode 33 and the second electrode 34 also have a compound R with different curvatures in the middle.
It may also consist of: In particular, the first electrode 33 and the second electrode 3 of the narrow area stimulation head 19
Regarding the externally protruding curved surface of No. 4, if the curvature on the bent side is set small, and the curvature from the middle far from the bent part to the end is larger than the curvature on the bent side, the depression will be reduced. Certain skin areas can be treated accurately. Furthermore, regarding the first electrode 33 and the second electrode 34 of the narrow-area stimulation head 19, the surface on the side of the bending part is an inwardly concave curved surface, and the outwardly protruding curved surface is formed from the middle away from the bending part as described above. It can be configured so as to be continuously connected to an inner concave curved surface. According to this, thermal stimulation can be performed at specific points on the skin. Note that 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 may be curved surfaces with an external protrusion. According to such a beauty instrument, when beauty treatment is performed using the narrow-area stimulation head 19, it is possible to accurately perform beauty treatment on skin areas with depressions such as around the nose.

In the twelfth embodiment, the same control as in the first embodiment 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. 7, when the detection signal of the current value detection unit 50 is larger than the threshold value (reference current value) Among the skin electrodes 22 and 32, it is determined that the electrode surface (skin contact surface) of the skin electrode 22 of the wide-area stimulation head 18 is in contact with the skin surface, and the high-frequency current is supplied to the skin electrode 22. Increase the output value of (supplied power) to or above 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 of the skin electrodes 22 and 32 comes into contact with the skin surface. 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 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, each of the electrodes 33 and 34 There is a risk that the amount of electricity converted into heat between the skin and the skin will increase, causing unnecessary heating of the skin. In order to solve this problem, the control section 48 detects that the skin electrode 32 of the narrow-area stimulation head 19 is applied to the skin from the current value of the current value detection section 50, as described above. The high frequency current supplied to the skin electrode 32 is lower than the high frequency current supplied to the skin electrode 22. In addition. In 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 area stimulation head 19 and the area and heat capacity of the skin electrode 22 of the wide area stimulation head 18. be. Therefore, the temperature of the skin electrode 32 of the narrow-area stimulation head 19, which has a small heat dissipation area, tends to rise easily. However, in the case of this embodiment, since the first electrodes 23, 33 and the second electrodes 24, 34 are integrated and connected, the temperature rise of the skin electrode 32 of the narrow area stimulation head 19 is different from that in the embodiment 1. Not so much.

In the twelfth embodiment, as in the first embodiment, the threshold value (operating temperature) of the temperature sensor 27 is set to 45.
The threshold value (operating temperature) of the temperature sensor 37 is set at 43°C. That is, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow area stimulation head 19 is set smaller than the threshold value of the detection signal of the temperature sensor 27 provided in the wide area stimulation head 18. In this way, if the threshold value of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set small, when a high-frequency current is supplied to the skin electrode 32 of the narrow-area stimulation head 19, the skin electrode 32 will not come into contact with the skin electrode 32. It can prevent your skin from getting too hot.

The beauty instrument according to Example 12 can be implemented in the following form.
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 the 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 and long. It is formed into a shaft shape,
The first electrodes 23, 33 and the second electrodes 24, 34 are arranged in parallel with a predetermined interval,
The total surface area of the first electrode 23 and the second electrode 24 that constitute the skin contact body 22 of the wide area stimulation head 18 is equal to the total surface area of the first electrode 33 and the second electrode 34 that constitute 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 instrument according to the twelfth embodiment, by using the wide-area stimulation head 18, it is possible to suitably perform beauty treatments on flat and large skin surfaces such as cheeks and foreheads. It can be used to accurately perform beauty treatment on narrow skin areas such as around the nose and eyes.

In the beauty instrument according to the twelfth embodiment, 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 continuous curved planes. 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 of continuous curved planes. According to such a heating head, each stimulation head 18, 19 has a first electrode 23
- Compared to the case where the electrode 33 and the second electrodes 24 and 34 are provided separately, the number of parts can be reduced and the electrode structure can be simplified, and the cost of the beauty instrument can be reduced accordingly. Furthermore, 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 using one stimulation head 18 (or 19), The other stimulation head 19 (
Alternatively, the stimulation head 18) can be prevented from coming into contact with the skin surface, and the beauty treatment by the stimulation heads 18 and 19 can be performed appropriately.

In the beauty instrument according to the twelfth embodiment, a 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 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.
A temperature sensor 37 is provided inside at least one of the electrode 33 and the second electrode 34. In addition, the threshold value of the temperature sensor 37 provided in the narrow area stimulation head 19 was set to be smaller than the threshold value of the temperature sensor 27 provided in the wide area stimulation head 18. According to such a thermal head, when a high frequency current is supplied to the skin electrode 32 of the narrow area stimulation head 19, the threshold value of the temperature sensor 37 is set low, so the temperature of the skin in contact with the skin electrode 32 is high. It can prevent the temperature from getting too high.
When the skin electrode 32 of the narrow area stimulation head 19 is applied to the skin, the high frequency current supplied to the skin electrode 32 is lower than the high frequency current supplied to the skin electrode 22. According to such a thermal head, since the area of the skin electrodes 32 of the narrow-area stimulation head 19 is small, if the same high-frequency current is supplied to the skin electrodes 32 as when applying the skin electrodes 22 of the wide-area stimulation head 18 to the skin surface, each electrode There is a risk that the electric power converted into heat between 33 and 34 will be large and the skin will be heated unnecessarily, but this can be prevented.

(Example 13) FIG. 23 shows Example 13 of the beauty instrument according to the present invention. In the beauty instrument of Example 12, a wide area stimulation head 18 is provided near the top of the main body case 1, a narrow area stimulation head 19 is provided at the upper end of the main body case 1, and the first electrode 23 of the wide area stimulation head 18 and the first electrode 19 are provided at the upper end of the main body case 1. 2 electrodes 24
, and the first electrode 33 and second electrode 34 of the narrow-area stimulation head 19 were each constructed from rotatable rollers. Specifically, two first electrodes 23 and two second electrodes 24 of the wide area stimulation head 18 are arranged alternately, three insulating rollers 61 are arranged between each electrode 23 and 24, and these are connected to the main body case 1. It was rotatably supported by a roller shaft 62 fixed to. Similarly, the first electrode 33, insulated 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 main body case 1. First electrode 23 on the skin electrode 22 side
The width and diameter of the second electrode 24 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 electrode parts can be shared. 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 made larger than the contact area of the skin electrode 32 with the skin. In this way, the following configuration can be adopted to make the contact area of each skin electrode 22 and 23 with respect to the skin different in size. The width dimensions of the first electrode 23 and second electrode 24 on the skin electrode 22 side and the first electrode 33 and 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 second electrode 34 on the skin electrode 32 side.
The area of contact with the skin of the skin electrode 32 is made to vary in size. In addition, each electrode 23, 24
- Make the diameters of 33 and 34 the same, and the width of the first electrode 23 and second electrode 24 on the skin electrode 22 side,
The width of the first electrode 33 and the second electrode 34 on the skin electrode 32 side is set larger than that of the skin electrode 22, 32.
The area of contact with the skin may be varied in size. In addition, each electrode 23, 24, 33, 34
The cross-sectional shape of may be polygonal. Moreover, the cross-sectional shape of each electrode 23, 24, 33, and 34 may be made circular as it is, and a plurality of convex portions or concave portions may be provided evenly on the circumferential surface. This can be expected to have a stimulating effect on the skin.

In this embodiment, the first electrode 33, the second electrode 34, and the insulating roller 63 in the narrow area stimulation head 19 are configured to rotate together, but as a modified example, the above three are configured to rotate independently. It can be done. Thereby, when moving the narrow area stimulation head 19 on the skin surface, the direction can be changed smoothly. In addition, the two first electrodes 23, two second electrodes 24, and three insulating rollers 61 in the wide-area stimulation head 18 are configured to rotate together, but the above three are also independent of each other. It can be configured to rotate as shown in FIG. However, considering quality and cost aspects, the first electrode 33, second electrode 34, and insulating roller 63 in the narrow-area stimulation head 19 should be a unit that rotates as one unit, while the two electrodes in the wide-area stimulation head 18 should be Regarding the first electrode 23, the two second electrodes 24, and the three insulating rollers 61, the first electrode 23, the second electrode 24, and the insulating roller 61 on the left side are made into a unit that can rotate as one, and the first electrode 23 on the right side The second electrode 24 and the insulating roller 61 are configured to be an integrally rotatable unit that can rotate left and right independently. Regarding the central insulating roller 61,
It may be configured to rotate integrally with either the left or right unit, or may be configured to rotate independently.

In this embodiment, the narrow area stimulation head 19 is fixed, but as a modification, the narrow area stimulation head 19 can be provided to be expandable and retractable 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 expanded and contracted together with the roller shaft 62 with respect to the main body case 1. A moderating structure (convex part) is provided in the part of the roller shaft 62 located inside the main body case 1, and by engaging with the corresponding moderating structure (three concave parts) inside the main body case 1, Positioning can be done at three locations: high position and high position. This telescopic structure allows the narrow-area stimulation head 19 to 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. Further, the narrow area stimulation head 19 can be configured to be completely stored in the main body case 1. In this case, there are four points of moderation. This configuration allows protection of the narrow area stimulation head 19. Although the wide-area stimulation head 18 is also fixed in this embodiment, it can be provided to be expandable and retractable like the narrow-area stimulation head 19 described above. The stretching direction in this case is the front-back direction.

Further, in this embodiment, the narrow area stimulation head 19 is fixed, but 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 together with the roller shaft 62 against the main body case 1. Specifically, two coil springs (springs) are provided inside the main body case 1, and the above-mentioned springs are inserted into the left and right ends of the roller shaft 62, and these springs are separately inserted into the left and right ends of the roller shaft 62. The narrow area stimulation head 19 is elastically biased upward by pressing against two fixed abutting pieces. The two contact pieces are restricted from moving upward by contacting the inner wall around the opening of the main body case 1 into which the roller shaft 62 is loosely fitted. This restricts the upward movement of the narrow area stimulation head 19 as a whole. When the narrow area stimulation head 19 is pressed against the skin, the narrow area stimulation head 19 sinks into the main body case 1 due to the pressing force, so that it can follow the unevenness of the skin and reduce the burden on the skin. . Although the wide-area stimulation head 18 is also fixed in this embodiment, it can be configured to be elastically biased similarly to the above-mentioned narrow-area stimulation head 19. In this case, the direction in which the elastic force is applied is not the up-down direction but the front-back direction. Furthermore, 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 activated during thermal stimulation, the narrow-area stimulation head 19 and/or the wide-area stimulation head 18 can be vibrated in the direction in which they are elastically biased, thereby applying small vibration stimulation to the skin. be able to.

Further, in this embodiment, the wide area stimulation head 18 includes two first electrodes 23 and two second electrodes 2.
For example, the diameter of the first electrode 23 on the left end and the diameter of the second electrode 24 on the right end remain the same, and the diameters of the second electrode 24 and the first electrode 23 on the inside (closer to the center) are the same. The diameter of the first electrode 23 on the left end and the second electrode 24 on the right end can be made one size larger. This makes it easy to bring all the electrodes into contact with the skin surface of the recessed area (for example, under the chin), allowing appropriate thermal stimulation to be applied to the skin.

In addition, in this embodiment, the narrow area stimulation head 19 and the wide area stimulation head 18 each include the electrodes 23 and 24.
・It is a passive rotating structure in which rollers 33 and 34 are rotated by pressing them against the skin and moving them, but it is also possible to have a structure in which power such as a motor is provided to rotate actively. .

Furthermore, in this embodiment, the narrow area stimulation head 19 is provided on the top wall of the main body case 1, and the wide area stimulation head 18 is provided on the front wall of the main body case 1. It can be provided in

For example, a rectangular frame is rotatably attached to the roller shaft 64, and the narrow area stimulation head 19 is placed on one side of the upper side of the frame, and the wide area stimulation head 18 is placed on one side of the lower side of the opposite side. It can be provided as possible. The portion of the frame attached to the roller shaft 64 is the center portion of the left and right sides of the frame. Thereby, by rotating the frame, the narrow-area stimulation head 19 or the wide-area stimulation head 18 can be used alternatively. Therefore, ease of use can be improved without making mistakes.
The basic structure of the beauty instrument of Example 13 other than the electrode shape and arrangement is the same as the beauty instrument of Example 1.

(Actions and effects of beauty instruments explained in each example)
In the beauty instruments described in each of the above embodiments, the heating head 2 provided in the main body case 1 includes a wide area stimulation head 18 that provides beauty stimulation to a wide area of the skin surface, and a wide area stimulation head 18 that provides beauty stimulation to a narrow area of the skin surface. A narrow area stimulation head 19 is provided. Furthermore, the wide-area stimulation head 18 and the narrow-area stimulation head 19 are each provided with skin contact bodies 22 and 32 that apply beauty stimulation to the skin surface. According to such a beauty device, by using the wide-area stimulation head 18, it is possible to suitably perform beauty treatments on flat and large skin surfaces such as cheeks and foreheads, as well as the narrow-area stimulation head 1.
9 makes it possible to accurately perform beauty treatments on narrow skin areas such as around the nose and around the eyes. Therefore, it is possible to provide a beauty instrument that can evenly apply beauty treatments to the entire facial skin. In addition, each stimulation head 18
Since dedicated skin contacting bodies 22 and 32 are provided at 19, it is possible to reliably heat the skin and apply electrical stimulation to the skin.

The electrode surface of the skin electrode 32 of the narrow area stimulation head 19 is made to be inclined with respect to the electrode surface of the skin contact body 22 of the wide area stimulation head 18. According to these beauty devices, one stimulation head 18
(or 19), the other stimulation head 19 (or 18) does not come into contact with the skin surface, so each stimulation head 18, 19 can perform beauty treatment appropriately.

The head surface 30 that supports the skin contact body 32 of the narrow area stimulation head 19 is made to be inclined with respect to the head surface 20 that supports the skin contact body 22 of the wide area stimulation head 18. According to such a beauty device, the wide area stimulation head 18 and the narrow area stimulation head 19 can be distinguished not only by the difference in area of each stimulation head 18 and 19 but also by the difference in inclination, and in particular, the narrow area stimulation head 19 is used. The user can intuitively recognize the target area for beauty treatment. Therefore, it is possible to effectively prevent each stimulation head 18, 19 from being used incorrectly.

Each of the wide-area stimulation head 18 and the narrow-area stimulation head 19 is provided with temperature sensors 27 and 37 for detecting skin temperature. According to such a beauty device, each stimulation head 18.
Since the temperature state of the skin contact bodies 22 and 32 at step 19 can be accurately detected, the skin temperature can be reliably prevented from becoming higher than necessary, and beauty treatments can be performed safely.

Either one of the temperature sensor 27 provided on the wide area stimulation head 18 and the temperature sensor 37 provided on the narrow area stimulation head 19 is made to serve as an environmental temperature sensor for the environment in which the beauty instrument is used. According to such a beauty device, when performing beauty treatment using the wide-area stimulation head 18, for example, the temperature sensor 37 provided in the narrow-area stimulation head 19 detects the environmental temperature, and The operating state of the wide-area stimulation head 18 can be adjusted accordingly. For example, in the summer when the environmental temperature is high, the drive current supplied to the skin contact body 22 is adjusted to be higher than the standard output value, and in the winter, the drive current supplied to the skin contact body 22 is adjusted to be lower than the standard output value. Control such as adjustment can be performed. In addition, in the case of a heating head 2 in which a heating source such as a PTC heater is provided inside the skin contacting body 22, it is possible to adjust the drive wave current supplied to the heating source to respond to differences in environmental temperature. can.

A high frequency voltage is applied to the skin contacting bodies 22 and 32, and the skin is heated by the heat generating effect of the high frequency current flowing through the skin. According to these beauty devices, the skin can be heated from the inside by the heat generation effect of high-frequency current flowing through the skin.For example, by pressing the heated thermal head 2 against the skin surface, the skin can be heated by heat conduction from the skin surface to the inside of the skin. Compared to heating the skin, the skin can be heated more quickly and efficiently.

The skin contact bodies 22 and 32 of each stimulation head 18 and 19 are connected to the first electrodes 23 and 33 and the second electrode 24.
34, and the control unit 4 controls the supply state of the high frequency current supplied to each skin contact body 22, 32.
8 is adjusted according to the threshold values of the detection signals of the temperature sensors 27 and 37. Then, the threshold value of the detection signal of the temperature sensor 37 provided in the narrow-area stimulation head 19 is set to
The threshold value of the detection signal of the temperature sensor 27 provided at 8 is set to be smaller than the threshold value of the detection signal. In this way, if the threshold of the detection signal of the temperature sensor 37 of the narrow area stimulation head 19 is set small,
Since the temperature of the narrow area stimulation head 19 can be controlled from a low temperature stage compared to the wide area stimulation head 18, it is possible to prevent the narrow area stimulation head 19 from falling into a high temperature state.

A common electrode 36 is configured 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 adjacent to the wide area stimulation head 18 and the narrow area stimulation head 19. did. According to such a heating head 2, each stimulation head 18, 19 has a second electrode 24, 3.
Compared to the case where 4 are provided individually, the number of parts can be reduced and the electrode structure can be simplified, and the cost of the beauty instrument can be reduced accordingly. In addition, each electrode 23 and 24 in the wide area stimulation head 18
The protrusion height from the head surface 20 of the second electrode 24 constituting the common electrode 36 is
The height was set equal to or greater than the height of the protrusion. Furthermore, the protrusion height of each electrode 33 and 34 from the head surface 30 in the narrow-area stimulation head 19 is made smaller than the protrusion height from the head surface 20 of the second electrode 24 on the wide-area stimulation head 18 side that constitutes the common electrode 36. Set. According to such a beauty instrument, the first electrode 33 of the narrow area stimulation head 19 and the second electrode forming the common electrode 36
The plane that connects the electrodes 34 (the plane that contacts the skin) intersects the plane that connects the first electrode 23 of the wide-area stimulation head 18 and the second electrode 24 that constitutes the common electrode 36 (the plane that contacts the skin). I can do it. Therefore, for example, when performing beauty treatment using the narrow-area stimulation head 19, it is possible to effectively prevent the electrodes 23 and 24 of the wide-area stimulation head 18 from coming into contact with the skin surface.

The head surface 30 of the narrow area stimulation head 19 is connected to the second electrode 24 that constitutes the common electrode 36.
34 to the end of the head of the narrow area stimulation head 19. According to such a beauty device, the posture of the thermal head 2 that is in close contact with the skin differs greatly between when using the wide area stimulation head 18 and when using the narrow area stimulation head 19, so the narrow area stimulation head 19 is used. When performing beauty treatment, each electrode 23 and 2 of the wide area stimulation head 18
4 can be further reliably prevented from coming into contact with the skin surface.

When the head surface 30 on the narrow-area stimulation head 19 side is tilted backward relative to the head surface 20 on the wide-area stimulation head 18 side, the posture of the beauty instrument when each stimulation head 18, 19 contacts the skin surface is adjusted. Furthermore, since there is a large difference, when performing beauty treatment using the narrow area stimulation head 19, 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.

In the adjacent part of 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 integrated to form a common electrode 36. did.
