[1] Example

1 shows the appearance of the facial device 1 of the embodiment. In FIG. 1A, the external appearance of the facial device 1 is shown, and in FIG. 1B, the state which covered the face device 1 with the cotton 70 is shown. Figure 2 shows the front, side, and back of the facial device (1). The front side is shown in FIG. 2A, the side surface in FIG. 2B, and the back surface is shown in FIG. 2C.

The facial device 1 is a mechanism which mainly applies a beauty process to a user's face, and is an example of "beauty processing apparatus" of this invention. The facial device 1 includes a head 10 and a main body 50 . The head part 10 is a part that is pressed against the user's skin. The main body 50 is a rod-shaped part having a first face 51, two second faces 52 and a third face 53, which are all elongated faces, and is a part held by the user. . The main body 50 is an example of the "grip part" of this invention. The head 10 is provided at one end of the first surface 51 in the longitudinal direction A1 of the main body 50 .

In the face device 1, the side to which the 1st surface 51 is facing, ie, the side where the head part 10 is provided, is set as a front, and the side to which the 2nd surface 52 is facing is a side surface, the 3rd Let the side to which the surface 53 faces be a back surface. An operation button 54 operated by a user is provided on the first surface 51 . The operation button 54 may be a touch type switch displayed on the liquid crystal panel or a mechanical switch. The operation button 54 accepts an operation to select an operation mode of the facial device 1 and an operation to start an operation in the selected operation mode.

In this embodiment, the configuration related to the operation in the cleansing mode for removing contaminants from the skin while performing deep heating to warm the deep layers of the skin will be described. The head portion 10 includes an electrode portion 20 , a columnar portion 30 , and a stopper 40 . Both of the deep heating and decontamination described above are performed by applying an electric current to the skin. The electrode part 20 is a part provided with an electrode to which a voltage for flowing a current to the skin is applied in deep heating and removal of contaminants. Hereinafter, a voltage for deep heating is referred to as a “first voltage”, and a voltage for removing contaminants is referred to as a “second voltage”. The electrode unit 20 includes a first electrode 21 and a second electrode 22 .

The first electrode 21 has a circular outer periphery, and in the present embodiment is an annular electrode with an open center. The second electrode 22 is an annular electrode having an open center, and is disposed concentrically with the first electrode 21 and outside the outer periphery of the first electrode 21 . Due to their shape and arrangement, the distance between the first electrode 21 and the second electrode 22 is constant anywhere on the circumference. Between the first electrode 21 and the second electrode 22, a high-frequency voltage (also referred to as a high-frequency voltage or RF (Radio Frequency) voltage) is applied as the above-described first voltage.

The columnar portion 30 is a columnar portion having a circular cross section, and has a cylindrical shape in the present embodiment. The columnar part 30 has a bottom surface 31 and a side surface 32 , and the electrode part 20 is attached to the bottom surface 31 . The bottom surface 31 is an example of the "mounting surface" of this invention. The columnar part 30 has a housing which forms the internal space in which wiring etc. are arrange|positioned, The housing is formed using electrical insulation materials, such as plastics, a nonmetal, or ceramic. Accordingly, even when a voltage is applied to the electrode unit 20 , current does not flow through the housing of the columnar unit 30 , but current flows through the user's skin.

A ring 60 is fitted into the columnar portion 30 . The ring 60 is an annular magnetic body whose inner diameter is larger than the outer periphery of a columnar part. The ring 60 is formed of a material exhibiting ferromagnetism, such as iron, cobalt, nickel, an alloy thereof, or ferrite, for example. The stopper 40 is formed on the opposite side of the bottom surface 31 of the columnar portion 30 , and is a portion for holding the ring 60 when the ring 60 is fitted into the columnar portion 30 . .

The stopper 40 has a magnet part 41 and a cutout part 42 . The magnet portion 41 has four magnets each embedded in the stopper 40 in this embodiment. The bottom surface 31 of the columnar portion 30 is covered with cotton 70 formed of cotton fibers in a sheet shape as shown in FIG. 1B . Cotton 70 is an example of the "porous covering body" of this invention. In this way, the ring 60 attracted to the magnet part 41 and the columnar part 30 (specifically, its side surface 32) are pinching and fixing the cotton 70 covering the bottom surface 31 .

The stopper 40 has an annular shape, and a notch 42 is formed by cutting out a part of the outer peripheral side.

3 is an enlarged view of the stopper 40 and the like. In FIG. 3, the 1st electrode 21, the 2nd electrode 22, and the ring 60 are hatched and shown for easy identification. The first electrode 21 , the second electrode 22 , the columnar portion 30 , and the stopper 40 (circular outer peripheral portion) are all arranged so as to be concentric with the central point P1 as the center.

Moreover, the ring 60 fitted into the columnar part 30 also becomes a state substantially concentric with these. Assuming that the direction from the central point P1 to the outer periphery is the radial direction A2, the cut-out portion 42 in the stopper 40 is in a radial direction from the circular outer periphery of the ring 60 fitted into the columnar portion 30. is made up of small parts. That is, it is the dimension B1 of the outer peripheral radial direction A2 of the ring 60 > dimension B2 of the radial direction A2 of the cutout part 42 of the stopper 40, and it is set.

By providing the cutout 42, the ring 60 in a state in which the cotton 70 is fixed can be pressed from the back side. It is easy to bet. In addition, the columnar part 30, the stopper 40, and the ring 60 should just be in the shape which can fix the cotton 70 in this way. For example, the columnar portion may be in the form of a truncated cone whose cross section becomes smaller as it approaches the bottom surface 31 . In addition, the stopper may have a polygonal plate-like shape, or may have a circular plate shape having a smaller radius than the outer periphery of the ring 60 and no cutouts (even though the ring 60 can be held, the ring 60 can be Because it can be pressed from the back side).

The portion covering the bottom surface 31 of the columnar portion 30 among the fixed cotton 70 is a contact portion 71 that comes into contact with the user's skin. The contact portion 71 is a portion to which contaminants of the skin are attached when the head portion 10 of the facial device 1 operating in the cleansing mode is pressed against the user's skin. In the cleansing mode, the lotion for cleansing is made to permeate the contact part 71 to make it easy to remove the dirt.

A third electrode 55 is provided on the third surface 53 of the main body 50 . The third electrode 55 is an elongated elliptical electrode extending from the end of the third surface 53 in the longitudinal direction A1 to the end. Since the third electrode 55 is provided in such a wide range, the user's hand holding the main body 50 is always in contact. The above-described second voltage (voltage for removing contaminants) is applied between the third surface 53 and the electrode part 20 .

As the second voltage, a DC voltage or a pulse voltage is used. The DC voltage is a voltage that has a constant magnitude and direction, and a DC current flows when applied. In addition, if the direction is constant even if the magnitude is not constant and slightly fluctuates, it may be regarded as a DC voltage. In addition, the pulse voltage refers to a voltage when a period in which a DC voltage is applied and a period in which a DC voltage is not applied are alternately repeated. Hereinafter, a case in which a pulse voltage is used as the second voltage will be described, but a DC voltage may be used instead of the pulse voltage.

4 shows the configuration of the electronic circuit of the facial device (1). The facial device 1 includes, in addition to the electrode portion 20 and the third electrode 55 having a first electrode 21 and a second electrode 22 , a first power source unit 81 and a second power source unit 82 . ), a voltage control unit 83 , and a control circuit board 80 having a resistance measuring unit 84 . The control circuit board 80 is a board on which a circuit for controlling a voltage is provided, and is constituted by electronic elements (eg, capacitors, coils, IC chips, memory, etc.).

The first power supply unit 81 applies a high-frequency voltage as a first voltage between the first electrode 21 and the second electrode 22 . The first power supply unit 81 has an oscillation circuit for generating a high-frequency voltage, a boosting circuit for boosting the oscillated voltage, and the like, and applies a high-frequency voltage of, for example, about 1 [MHz] to 4 [MHz]. When the user's skin is pressed against the head 10 in a state in which the high-frequency voltage is applied by the first power source 81 , a high-frequency current flows through the skin lotion soaked in the cotton 70 .

Since the distance between the first electrode 21 and the second electrode 22 is constant anywhere on the circumference as described above, a high-frequency current is uniformly generated between the first electrode 21 and the second electrode 22. flows Therefore, with respect to the user's skin positioned between the first electrode 21 and the second electrode 22, it becomes possible to make a high-frequency current flow widely and evenly, and the heat-generating area of the user's skin is wide and energized. stimulation is equalized. As a result, for example, compared to the case where a high-frequency current flows between spherical electrodes, the calorific value per unit area of the skin is reduced, and the skin is locally heated by the high-frequency current, which has been considered a problem in the past. It is designed to be easy to have or to prevent the user from feeling uncomfortable.

The second power supply unit 82 includes an oscillation circuit for generating a pulse voltage, a boosting circuit for boosting the oscillated voltage, and the like, and includes an electrode unit 20 (one of the first electrode 21 and the second electrode 22 or Both) and a pulse voltage is applied between the third electrode 55 . When the user holds the main body 50 of the facial device 1 and presses the head 10 against the skin, the hand in contact with the third electrode 55 and the lotion soaked in the cotton 70 enter the user's body. A weak direct current flows.

In the case of the cleansing mode, the second power supply unit 82 applies a pulse voltage such that the third electrode 55 side has a negative potential with respect to the electrode unit 20 . Thereby, the skin side has a negative potential with respect to the head portion 10 , and so-called ion derivation is performed in which wastes and contaminants, etc. that have been negatively charged and adhered to the skin are adsorbed to the cotton 70 . In the facial device 1, deep heating by a high-frequency voltage and removal of contaminants by a pulse voltage are alternately performed.

The voltage control unit 83 controls the high frequency voltage applied by the first power supply unit 81 by controlling the first power supply unit 81 , and controls the second power supply unit 82 to control the pulses applied by the second power supply unit 82 . control the voltage. The voltage control unit 83 is an example of the "control unit" of the present invention. The voltage control unit 83 controls so that the first period for applying the high frequency voltage and the second period for applying the pulse voltage alternately come. The voltage control unit 83 controls, for example, to make the first period and the second period the same length (for example, about 5 to 15 seconds).

Moreover, the voltage control part 83 uses the measurement result by the resistance measuring part 84 for control of both voltages.

The resistance measuring unit 84 measures a resistance value between the first electrode 21 and the second electrode 22 . The resistance measuring unit 84 measures the electrical resistance (resistance) as a resistance value in the present embodiment. As shown in FIG. 1B, the resistance measuring unit 84 is the first electrode 21 in a state in which the cotton 70 is fixed and the lotion is soaked (the state before the head 10 is pressed against the user's skin). And since a current flows in the lotion by the high-frequency voltage applied between the second electrode 22, the resistance value of the lotion is measured. And, in a state in which the head unit 10 is pressed against the user's skin, current flows through the user's skin through the lotion, so the resistance measuring unit 84 measures a resistance value indicating the combined resistance of the lotion and the user's skin. do.

This resistance value (electrical resistance) changes depending on the condition of the user's skin, the ingredients of the lotion, and the like.

For example, it is known that when a high-frequency current flows through the skin of a human body, the skin heats up and the impedance inside the skin gradually decreases with the increase in the skin temperature. Accordingly, as the skin temperature rises, the amount of current flowing between the first electrode 21 and the second electrode 22 increases, and the measured resistance value decreases. The resistance measuring unit 84 measures the resistance value at a determined time interval (for example, every 0.5 second or the like), and outputs the measured resistance value to the voltage control unit 83 each time.

The voltage control part 83 controls the high frequency voltage and the pulse voltage according to the resistance value measured by the resistance measuring part 84 in this way. The voltage control unit 83, for example, increases the high-frequency voltage as the measured resistance value increases (increases the amplitude of the high-frequency voltage). In order to perform this control, the voltage control part 83 memorize|stores the 1st control table which made the range of resistance values and the high frequency voltage correspond, for example.

5 shows an example of the first control table. In the example of FIG. 5 , the high-frequency voltages “Vrf1”, “Vrf2”, and “Vrf3” in the resistance values range of “less than R11”, “R11 or more and less than R12” and “R12 or more” (Vrf1 < Vrf2 < Vrf3) This is matched. When the measurement result is supplied from the resistance measuring unit 84 , the voltage control unit 83 applies a high frequency voltage corresponding to the resistance value range including the measurement result in the first control table. Accordingly, the voltage control unit 83 increases the high-frequency voltage as the resistance value measured as described above increases.

The larger the resistance value between the first electrode 21 and the second electrode 22, the smaller the current flowing through the skin when a high-frequency voltage is applied, and the harder it is to warm the inside of the skin. For example, when the lotion α is used, the resistance value becomes less than R11, and when the resistance value using the lotion β becomes R12 or higher, when the high-frequency voltage is the same, the latter is less likely to warm the inside of the skin than the former. Such a difference in the ease of warming the inside of the skin is caused by individual differences in skin for each user, and also by differences in skin conditions even for the same user.

Therefore, by performing the above control (control of the voltage by the voltage control unit 83), compared to the case where this control is not performed, skin damage caused by differences in conditions such as individual differences in skin, skin condition and ingredients of lotion, etc. By reducing the difference in the magnitude of the flowing current, it is possible to reduce the internal temperature difference of the skin (that is, the difference in the deep thermal effect). In addition, as the skin temperature rises, the resistance value decreases as described above, so the high-frequency voltage also decreases. Thereby, it is also possible to prevent excessive heating of the inside of the skin. In addition, since the resistance measuring unit 84 measures the resistance value of the lotion even before the head unit 10 is pressed against the user's skin as described above, compared to the case where the above control is not performed, the head unit 10 ) before pressing against the user's skin, the difference in the magnitude of the current flowing through the skin (especially the difference caused by the difference in the ingredients of the lotion) can be reduced.

In addition, the voltage control unit 83 increases the pulse voltage as the measured resistance value increases (increases the DC voltage included in the pulse voltage). In order to perform this control, the voltage control part 83 memorize|stores the 2nd control table which made the range of a resistance value and the pulse voltage correspond, for example.

6 shows an example of the second control table. In the example of Fig. 6, pulse voltages of "Vp1", "Vp2", and "Vp3" (Vp1<Vp2<Vp3) in the resistance value ranges of "less than R21", "R21 or more and less than R22", and "R22 or more" This is matched.

When the measurement result is supplied from the resistance measuring unit 84 , the voltage control unit 83 applies a pulse voltage corresponding to the resistance value range including the measurement result in the second control table. Accordingly, the voltage control unit 83 increases the pulse voltage as the measured resistance value increases as described above.

The larger the resistance value between the first electrode 21 and the second electrode 22, the smaller the current flowing through the skin when a pulse voltage is applied, and the fewer contaminants and the like adsorbed to the cotton 70 (Ion derivation). less effective). Therefore, by performing the above control, the difference in the magnitude of the current flowing through the skin due to individual differences in the skin, the condition, and the difference in the conditions such as the components of the lotion is reduced, and the difference in the contaminants etc. adsorbed to the cotton 70 (i.e. difference in the effect of ion derivation) can be made small.

In addition, the voltage control unit 83 lengthens the first period for applying the high-frequency voltage as the measured resistance value increases. In order to perform this control, the voltage control part 83 memorize|stores, for example, the 3rd control table which made the range of the resistance value and the 1st period correspond.

7 shows an example of the third control table. In the example of Fig. 7, in the resistance value ranges of "less than R31", "R31 or more and less than R32", and "R32 or more", the first period (Trf1<Trf2<Trf3) of "Trf1", "Trf2", and "Trf3" ) is matched.

When the measurement result is supplied from the resistance measuring unit 84 , the voltage control unit 83 applies the high frequency voltage during the first period corresponding to the range of resistance values including the measurement result in the third control table. Accordingly, the voltage control unit 83 lengthens the first period (period for applying the high-frequency voltage) as the resistance value measured as described above increases. In this case, in a situation where the inside of the skin is difficult to warm, the deep warming effect is enhanced by lengthening the first period.

For example, when it is difficult to warm the inside of the skin even when a high-frequency voltage is applied to the maximum, the deep warming effect can be enhanced by lengthening the first period. Conversely, when the inside of the skin becomes excessively warm even when a high-frequency voltage is applied to a minimum, the deep warming effect can be suppressed by shortening the first period. Also, even in the case of changing the first period, as in the case of changing the high-frequency voltage, the difference in the magnitude of the current flowing through the skin caused by differences in circumstances such as individual differences in skin, skin condition, and ingredients of lotion is reduced. , it is possible to reduce the internal temperature difference of the skin (that is, the difference in the deep heating effect).

In addition, the voltage control unit 83 lengthens the second period for applying the pulse voltage as the measured resistance value increases. In order to perform this control, the voltage control unit 83 stores, for example, a fourth control table in which a range of resistance values and a second period are associated with each other.

8 shows an example of the fourth control table. In the example of FIG. 8, in the resistance value ranges of "less than R41", "R41 or more and less than R42", and "R42 or more", the first period of "Tp1", "Tp2" and "Tp3" (Tp1<Tp2<Tp3 ) is matched.

When the measurement result is supplied from the resistance measurement unit 84 , the voltage control unit 83 applies a pulse voltage during the second period corresponding to the range of resistance values including the measurement result in the fourth control table. Accordingly, the voltage control unit 83 lengthens the second period (period for applying the pulse voltage) as the resistance value measured as described above increases. In this case, in a situation in which contaminants or the like are hardly adsorbed to the cotton 70, the effect of ion derivation is enhanced by lengthening the second period.

For example, when the contaminants or the like do not sufficiently adsorb to the cotton 70 even when the pulse voltage is applied to the maximum, the effect of ion derivation can be enhanced by lengthening the second period. Also, even in the case of changing the second period, similarly to the case of changing the pulse voltage, the difference in the magnitude of the current flowing through the skin caused by differences in circumstances such as individual differences in skin, skin condition, and ingredients of lotion is reduced. , it is possible to reduce the difference between contaminants and the like adsorbed to the cotton 70 (that is, the difference in the effect of ion derivation).

Incidentally, the first to fourth control tables are not limited to those shown in Figs. 5 to 8 . For example, the range of the resistance value may be two or more than four. Moreover, you may perform each said control using the relational expression of a resistance value, a high frequency voltage, a pulse voltage, and a 1st period or a 2nd period. In other words, any method may be used as long as the high-frequency voltage is increased, the pulse voltage is increased, and the first period or the second period can be lengthened as the resistance value is large.

The facial device 1 performs the voltage control process which controls a high frequency voltage and a pulse voltage based on said structure.

9 : shows an example of the operation procedure of the facial device 1 in a voltage control process. This operation procedure is started on the occasion of operation of making the operation mode of the facial device 1 into a cleansing mode, and starting an operation|movement is performed. First, the facial device 1 (the first power supply unit 81 or the second power supply unit 82) starts application of either a high frequency voltage or a pulse voltage (step S10). Which voltage is started may be determined in advance, or it may be the one applied at the time of the last completion|finish.

Next, the facial device 1 (resistance measuring part 84) measures the resistance value between the 1st electrode 21 and the 2nd electrode 22 (step S11). Then, the facial device 1 (voltage control part 83) determines the high frequency voltage to apply based on the measured resistance value (step S12). Next, the facial device 1 (voltage control part 83) determines the pulse voltage to apply based on the measured resistance value (step S13). Then, the facial device 1 (voltage control part 83) determines a 1st period and a 2nd period based on the measured resistance value (step S14). In addition, the operation|movement of steps S12 - S14 may change the order and may be performed in parallel.

Next, the facial device 1 (voltage control unit 83) determines whether or not the measurement interval has elapsed (step S21), and when it is determined that it has elapsed (YES), proceed to step S11 (measurement of resistance value) Go back and do the action. When it is determined that the facial device 1 (voltage control unit 83) has not elapsed (NO), the application period (the first period when a high-frequency voltage is currently being applied, or a pulse voltage is applied when It is determined whether or not the second period) has elapsed (step S22).

When it is judged that the facial device 1 (voltage control unit 83) has not elapsed (NO) in step S22, it returns to step S21 (judgment of the elapse of the measurement interval) and operates, and the elapsed time (YES) When it is determined, the voltage to be applied is changed (if a high frequency voltage is currently being applied, it is changed to a pulse voltage, and if a pulse voltage is being applied, it is changed to a high frequency voltage) (step S23). The facial device 1 (voltage control part 83) returns to step S21 (judgment of progress of a measurement interval) after step S23, and performs an operation|movement.

In this embodiment, by controlling the high-frequency voltage and the pulse voltage as described above, the difference in the magnitude of the current flowing through the skin caused by differences in circumstances such as individual differences in skin, skin condition, and ingredients of lotion is reduced, The difference in thermal effect and the effect of ion derivation are reduced. In this way, according to the present embodiment, it is possible to obtain the effect of a certain cosmetic treatment (the effect of deep warming effect and ion derivation) for various skin conditions.

In addition, in this embodiment, by applying a high-frequency voltage and a pulse voltage alternately, while warming the inside of the skin, cleansing is performed by ion derivation. As described above, the more the inside of the skin is warmed, the easier the current flows. Therefore, in this embodiment, by performing deep heating at the same time, the effect of ion derivation can be increased compared to the case where only the pulse voltage is applied.

In addition, in this embodiment, the cotton 70 is fixed by the magnetic ring 60 being attracted by the magnet part 41 provided in the stopper 40. As shown in FIG. In a state where the head part 10 is pressed against the user's skin, the magnetic force generated by the magnet part 41 exits the ring 60 and reaches the skin. As a result, a force is applied to the ions in the blood component to activate the ions' movement and promote blood circulation. In the face device 1, by utilizing the structure for fixing the cotton 70 (the magnet 41 and the ring 60) also to promote blood circulation, the device can be downsized compared to the case of using these other structures. .

[2] Modifications

The above-described embodiment is merely an example of implementation of the present invention, and may be modified as follows. In addition, you may implement each of the above-mentioned embodiment and each modification in combination as needed.

[2-1] Frequency control

In the above embodiment, the voltage control unit 83 controls the amplitude of the high-frequency voltage, however, the frequency of the high-frequency voltage may be controlled. Specifically, the voltage control unit 83 increases the frequency of the high-frequency voltage as the measured resistance value increases. The voltage control part 83 may perform this control using the control table as demonstrated with FIG. 5, and may perform this control using the relational expression of a resistance value and the frequency of a high frequency voltage.

It is known that the higher the frequency of the high-frequency voltage, the faster the internal temperature of the skin rises. Therefore, even by controlling the frequency of the high-frequency voltage as in this modified example, as in the case of controlling the high-frequency voltage in the example of FIG. 5 , the skin caused by differences in conditions such as individual differences in skin, skin condition, and ingredients of lotion By reducing the difference in the magnitude of the current flowing through the skin, the temperature difference inside the skin (that is, the difference in the deep heating effect) can be reduced, and excessive heating of the inside of the skin can be prevented.

Moreover, you may combine the frequency control of the high frequency voltage demonstrated in the said modification.

[2-3] Subjects of cosmetic treatment

In the above embodiment, the facial device, which is a mechanism for performing cosmetic treatment on the user's face, has been mainly described, but the present invention is not limited thereto. You may apply to the cosmetic treatment apparatus to do.

[2-4] Porous cover

In the above embodiment, cotton 70 obtained by molding cotton fibers into a sheet is used as a porous covering and covered on the bottom surface 31 of the columnar portion 30, but the present invention is not limited thereto. For example, hemp and silk, etc. What is formed in a sheet form of other types of fibers of the porous coating material may be used. In other words, as long as it has softness that can be covered on the bottom surface 31 of the columnar part 30, penetrates the lotion, and has a property of adsorbing contaminants when pressed against the skin, a porous covering of any material may be used. .

[2-5] Iontophoresis

In the above embodiment, the pulse voltage is applied so that the second power supply unit 82 conducts ion derivation. However, the pulse voltage may be applied to conduct ion introduction by reversing the plus and minus of the voltage. In this case, the lotion charged with anions is easily absorbed by the skin. In addition, since the skin is warmed to the inside by deep heat and the cells are activated, the lotion is more easily permeated.

[2-6] Operation mode

In the above embodiment, the facial device 1 was operated in the cleansing mode, but it is not limited to this, for example, it may operate in the mode for performing the above-described iontophoresis while performing deep heating, or a mode in which only deep heating is performed; The operation may be performed in a mode in which only removal of contaminants is performed or in a mode in which only iontophoresis is performed.

[2-7] Direct skin contact

In the above embodiment, although the facial device 1 is used in a state in which the cotton 70 is covered on the bottom surface 31 of the columnar part 30, it may be used in a state in which the cotton 70 is not covered. In that case, by operating the facial device 1 in, for example, a mode for performing only the deep heating described above, the resistance value is measured while the first electrode and the second electrode are in direct contact with the user's skin, and the measured resistance value Since a high-frequency voltage according to

[2-8] first electrode

In the above embodiment, the first electrode has an annular shape with an open center, but may have a disk shape without an open center. Even in that case, since the distance between the first electrode and the second electrode becomes constant anywhere on the circumference, the heat-generating area of the user's skin can be widened and the stimulation by electricity can be equalized.

[2-9] electrode part

In the above embodiment, both the electrode portions were provided with the first electrode and the second electrode having an annular shape, but the present invention is not limited thereto. The electrode portion may include, for example, polygonal and annular first and second electrodes, or rod-shaped first and second electrodes arranged in parallel. In either case, since it becomes possible to make a high frequency current flow more widely and uniformly, so that there are many parts used as the shortest distance between a 1st electrode and a 2nd electrode, it is also preferable.

[2-10] resistance value

In the above embodiment, the resistance measuring unit 84 measures the electrical resistance (resistance) as the resistance value between the first electrode 21 and the second electrode 22, but it is not limited thereto, and for example, You may measure the reactance between the 1st electrode 21 and the 2nd electrode 22 as a resistance value. In other words, a value indicating the difficulty in flowing current between the first electrode 21 and the second electrode 22 may be measured as the resistance value. Incidentally, a value indicating the easiness of the flow of current, such as conductance, may also be treated as a resistance value, since the reciprocal number indicates the difficulty of flowing the current.

[2-11] How to measure resistance value

In the above embodiment, the resistance measuring unit 84 causes the first electrode 21 and the second electrode 22 to flow by the current flowing when a high-frequency voltage is applied between the first electrode 21 and the second electrode 22 . Although the resistance value was measured, the measuring method of the resistance value is not limited to this. The resistance measuring unit 84 measures the current flowing when, for example, a measurement voltage (eg, DC voltage) for measuring a resistance value is applied between the first electrode 21 and the second electrode 22 . You may measure the resistance value between the 1st electrode 21 and the 2nd electrode 22 by this.

In this case, for example, before the first power supply unit 81 applies a high-frequency voltage for deep heating, the resistance measuring unit 84 measures the resistance value by first applying a measuring voltage, and according to the measured resistance value By controlling the voltage control unit 83 so that the high frequency voltage and pulse voltage are applied, the difference in the magnitude of the current flowing through the skin can be reduced from the start of the cosmetic treatment compared to the case where this control is not performed. . In addition, the resistance measuring unit 84 may measure the resistance value between them by installing a separate pair of electrodes on the bottom surface 31 of the columnar part 30 , and measure the electrical resistance on the bottom surface 31 . A sensor that outputs the indicated value may be installed and the resistance value may be measured using the output value.

In other words, the resistance value may be measured by any method as long as it is an index of the easiness of the flow of current in the portion where the head 10 is pressed against the user's skin. And, as in the embodiment, when the resistance measuring unit 84 measures the resistance value between the false first electrode 21 and the second electrode 22, there is no need to install another electrode or a sensor. Compared to the case of the present invention, the device can be miniaturized.
