[1] Embodiment FIG. 1 shows an appearance of a facial device 1 according to an embodiment. In FIG. 1 (a), only the appearance of the facial device 1 is shown, and in FIG. 1 (b), the state where the facial device 1 is covered with cotton 70 is shown. FIG. 2 shows the front, side, and back of the facial device 1. 2A shows the front, FIG. 2B shows the side, and FIG. 2C shows the back.

  The beauty face device 1 is an instrument that mainly performs a beauty treatment on a user's face, and is an example of the “beauty treatment apparatus” of the present invention. The beautiful face device 1 includes a head unit 10 and a main body 50. The head part 10 is a part pressed against the user's skin. The main body 50 is a rod-shaped portion having a first surface 51, two second surfaces 52, and a third surface 53, which are elongated surfaces, and is a portion gripped by a user. The main body 50 is an example of the “grip part” in the present invention. The head unit 10 is provided on one end of the first surface 51 in the longitudinal direction A1 of the main body 50.

  In the facial device 1, the direction in which the first surface 51 is facing, that is, the direction in which the head unit 10 is provided is the front, the direction in which the second surface 52 is facing is the side, and the third surface 53 is facing. The side is the back. The first surface 51 is provided with operation buttons 54 operated by the user. The operation button 54 may be a touch-type switch displayed on the liquid crystal panel or a mechanical switch. The operation button 54 receives an operation for selecting the operation mode of the facial device 1 and an operation for starting an operation in the selected operation mode.

  In the present embodiment, a configuration relating to an operation in a cleansing mode for removing dirt on the skin while performing deep layer heat for warming the deep layer of the skin will be described. The head unit 10 includes an electrode unit 20, a columnar unit 30, and a stopper 40. The above-described deep layer heat and dirt removal are both performed by passing an electric current through the skin. The electrode part 20 is a part provided with the electrode to which the voltage for sending an electric current to skin is applied in deep layer heat and dirt removal. Hereinafter, the voltage for deep layer heat is referred to as “first voltage”, and the voltage for removing dirt is referred to as “second voltage”. The electrode unit 20 includes a first electrode 21 and a second electrode 22.

  The first electrode 21 is an electrode having a circular outer periphery. In the present embodiment, the first electrode 21 is an annular electrode having an opening at the center. The second electrode 22 is an annular electrode having an opening at the center, and is concentric with the first electrode 21 and disposed outside the outer periphery of the first electrode 21. With these shapes and arrangements, the distance between the first electrode 21 and the second electrode 22 is constant everywhere on the circumference. A high frequency voltage (a voltage indicating a high frequency; also referred to as RF (Radio Frequency) voltage) is applied between the first electrode 21 and the second electrode 22 as the first voltage described above.

  The columnar part 30 is a columnar part having a circular cross section, and has a cylindrical shape in this embodiment. The columnar portion 30 has a bottom surface 31 and a side surface 32, and the electrode unit 20 is attached to the bottom surface 31. The bottom surface 31 is an example of the “mounting surface” in the present invention. The columnar portion 30 has a housing that forms an internal space in which wirings and the like are arranged, and the housing is formed using an electrically insulating material such as plastic, nonmetal, or ceramic. Thereby, even if a voltage is applied to the electrode part 20, an electric current does not flow into the housing | casing of the columnar part 30, but an electric current flows into a user's skin.

  A ring 60 is fitted into the columnar part 30. The ring 60 is an annular magnetic body having an inner diameter larger than the outer periphery of the columnar portion. The ring 60 is formed of a ferromagnetic material such as iron, cobalt, nickel, alloys thereof, or ferrite. The stopper 40 is connected to the opposite side of the bottom surface 31 of the columnar portion 30, and is a portion that stops the ring 60 when the ring 60 is fitted into the columnar portion 30.

  The stopper 40 has a magnet part 41 and a notch part 42. The magnet part 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 a cotton 70 in which cotton fibers are formed into a sheet shape as shown in FIG. Cotton 70 is an example of the “porous covering” of the present invention. In this way, the ring 60 attracted by the magnet portion 41 and the columnar portion 30 (specifically, the side surface 32) are sandwiched and fixed to 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 periphery thereof.
FIG. 3 is an enlarged view of the stopper 40 and the like. In FIG. 3, the first electrode 21, the second electrode 22, and the ring 60 are hatched for easy identification. The first electrode 21, the second electrode 22, the columnar portion 30, and the stopper 40 (circular outer peripheral portion thereof) are all arranged concentrically around the center point P1.

  Further, the ring 60 fitted into the columnar part 30 is also substantially concentric with these. Assuming that the direction from the center point P1 toward the outer periphery is the radial direction A2, the notch portion 42 has a smaller radial dimension than the circular outer periphery of the ring 60 in the stopper 40 in a state of being fitted into the columnar portion 30. It has become a part. That is, the dimension B1 in the radial direction A2 of the outer periphery of the ring 60> the dimension B2 in the radial direction A2 in the notch portion 42 of the stopper 40.

  By providing the notch portion 42, the ring 60 in a state where the cotton 70 is fixed can be pushed from the back side. Therefore, the ring 60 can be easily removed as compared with the case where the notch portion 42 is not provided. In addition, the columnar part 30, the stopper 40, and the ring 60 should just be the shape which can fix the cotton 70 in this way. For example, the columnar portion may have a truncated cone shape with a smaller cross section as it is closer to the bottom surface 31. Further, the stopper may have a polygonal plate shape, or may have a disk shape with a radius smaller than the outer periphery of the ring 60 and without a notch (still stopping the ring 60). Because the ring 60 can be pushed from the back side).

  A portion of the fixed cotton 70 that covers the bottom surface 31 of the columnar portion 30 is a contact portion 71 that contacts the user's skin. The contact portion 71 is a portion to which dirt on the skin adheres when the head portion 10 of the face device 1 operating in the cleansing mode is pressed against the user's skin. In the cleansing mode, the cleansing lotion is soaked into the contact portion 71 to easily 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 oval electrode that extends from end to end in the longitudinal direction A1 of the third surface 53. The third electrode 55 is provided in such a wide range, so that the user's hand holding the main body 50 always comes into contact. The above-described second voltage (voltage for removing dirt) is applied between the third surface 53 and the electrode unit 20.

  A DC voltage or a pulse voltage is used as the second voltage. A DC voltage is a voltage that is constant in magnitude and direction and flows a DC current when applied. It should be noted that if the direction is constant even if the magnitude is not constant but varies slightly, it may be regarded as a DC voltage. Further, 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 where a pulse voltage is used as the second voltage will be described, but a DC voltage may be used instead of the pulse voltage.

  FIG. 4 shows the configuration of the electronic circuit of the facial device 1. In addition to the electrode part 20 having the first electrode 21 and the second electrode 22 and the third electrode 55, the beauty device 1 includes a first power supply part 81, a second power supply part 82, a voltage control part 83, and resistance measurement. And a control circuit board 80 having a portion 84. The control circuit board 80 is a board provided with a circuit for controlling a voltage, and is configured by electronic elements (for example, a capacitor, a coil, an IC chip, a memory, and the like).

  The first power supply unit 81 applies a high frequency voltage as the first voltage between the first electrode 21 and the second electrode 22. The first power supply unit 81 includes an oscillation circuit that generates a high-frequency voltage, a boosting circuit that boosts the oscillated voltage, and the like, and applies a high-frequency voltage of, for example, about 1 [MHz] to 4 [MHz]. When the head unit 10 to which the high frequency voltage is applied by the first power supply unit 81 is pressed against the user's skin, a high frequency current flows through the skin 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, the distance between the first electrode 21 and the second electrode 22 is uniform. High frequency current flows. Therefore, it becomes possible to flow a high-frequency current over a wide range and evenly over the user's skin located between the first electrode 21 and the second electrode 22, the heat generation area of the user's skin is wide, and stimulation due to energization occurs. Become even. As a result, compared to the case where a high-frequency current is passed between spherical electrodes, for example, the amount of heat generated per unit area of the skin is reduced, and the skin is likely to have heat locally due to the high-frequency current that has been regarded as a problem in the past, The user is prevented from feeling uncomfortable.

  The second power supply unit 82 includes an oscillation circuit that generates a pulse voltage, a boosting circuit that boosts the oscillated voltage, and the like, and includes the electrode unit 20 (one or both of the first electrode 21 and the second electrode 22) and the third. A pulse voltage is applied between the electrodes 55. When the user grasps the body 50 of the facial device 1 and presses the head unit 10 against the skin, a weak direct current enters the user's body through the hand touching the third electrode 55 and the skin lotion soaked in the cotton 70. Current flows.

  In the cleansing mode, the second power supply unit 82 applies a pulse voltage to the electrode unit 20 so that the third electrode 55 side has a negative potential. As a result, the skin side has a negative potential with respect to the head unit 10, and so-called ion derivation is performed in which the waste, dirt, and the like that are negatively charged and adhere to the skin are adsorbed to the cotton 70. In the facial device 1, the deep layer heat by the high frequency voltage and the dirt removal by the 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 the pulse voltage applied by the second power supply unit 82 by controlling the second power supply unit 82. To control. The voltage control unit 83 is an example of the “control unit” in the present invention. The voltage control unit 83 performs control so that the first period during which the high-frequency voltage is applied and the second period during which the pulse voltage is applied alternately. For example, the voltage control unit 83 performs control so that both the first period and the second period have the same length (for example, about 5 to 15 seconds).

  Moreover, the voltage control part 83 uses the measurement result by the resistance measurement part 84 for control of both voltages. The resistance measuring unit 84 measures the resistance value between the first electrode 21 and the second electrode 22. In the present embodiment, the resistance measuring unit 84 measures an electrical resistance (resistance) as a resistance value. In the state where the cotton 70 is fixed and the skin lotion is soaked as shown in FIG. 1B (the state before the head unit 10 is pressed against the user's skin) as shown in FIG. Since a current flows through the lotion due to the high-frequency voltage applied between the second electrodes 22, the resistance value of the lotion is measured. And in the state which pressed the head part 10 to the user's skin, since an electric current flows into a user's skin via a lotion, the resistance measurement part 84 shows resistance value which shows the synthetic | combination resistance of a lotion and a user's skin. taking measurement.

  This resistance value (electrical resistance) varies depending on the user's skin condition, the type of skin lotion, and the like. For example, it is known that when a high-frequency current is passed through the human skin, the skin generates heat and the impedance inside the skin gradually decreases as the skin temperature rises. 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 measurement unit 84 measures the resistance value at a predetermined time interval (for example, every 0.5 seconds), and supplies the measured resistance value to the voltage control unit 83 each time.

  The voltage control unit 83 controls the high frequency voltage and the pulse voltage according to the resistance value thus measured by the resistance measurement unit 84. For example, the voltage control unit 83 increases the high-frequency voltage (increases the amplitude of the high-frequency voltage) as the measured resistance value increases. In order to perform this control, the voltage control unit 83 stores, for example, a first control table in which a resistance value range is associated with a high-frequency voltage.

  FIG. 5 shows an example of the first control table. In the example of FIG. 5, high-frequency voltages “Vrf1,” “Vrf2,” and “Vrf3” (Vrf1 <Vrf2 <Vrf3) are in the resistance value ranges of “less than R11”, “R11 or more and less than R12”, and “R12 or more”. Are associated. When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies the high-frequency voltage associated in the first control table to the range of the resistance value including the measurement result. Thereby, the voltage control part 83 makes high frequency voltage high, so that the resistance value measured as mentioned above is large.

  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 more difficult the inside of the skin gets warm. For example, when the lotion α is used and the resistance value is less than R11 and the resistance value using the lotion β is R12 or more, if 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 ease of warming inside the skin also occurs due to individual differences in the skin for each user, and also due to differences in the skin condition of the same user.

  Therefore, by performing the above-described control (voltage control by the voltage control unit 83), compared to a case where this control is not performed, it is caused by differences in the situation such as individual differences in skin, skin condition, and type of lotion. The difference in the magnitude of the current flowing through the skin can be reduced, and the temperature difference inside the skin (that is, the difference in the deep layer thermal effect) can be reduced. Further, when the skin temperature rises, the resistance value becomes small as described above, so that the high frequency voltage also becomes small. Thereby, it can also prevent that the inside of skin is heated too much. In addition, as described above, the resistance measuring unit 84 measures the resistance value of the skin lotion even in a state before the head unit 10 is pressed against the user's skin. Before pressing against the user's skin, the difference in the magnitude of the current flowing through the skin (particularly the difference caused by the type of lotion) can be reduced.

Further, 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 unit 83 stores, for example, a second control table in which a resistance value range is associated with a pulse voltage.
FIG. 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) are in the resistance value ranges of “less than R21”, “R21 or more and less than R22”, and “R22 or more”. Are associated.

  When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies the pulse voltage associated with the range of the resistance value including the measurement result in the second control table. Thereby, the voltage control unit 83 increases the pulse 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 that flows through the skin when a pulse voltage is applied, and the less dirt and the like adsorbs to the cotton 70 (the effect of ion derivation is smaller). Become). Therefore, by performing the above control, the difference in the magnitude of the current flowing through the skin due to the individual differences in the skin, the state and the difference in the type of skin lotion, etc., is reduced, so that the dirt adsorbed on the cotton 70 etc. The difference (that is, the difference in the effect of deriving ions) can be reduced.

Moreover, the voltage control part 83 lengthens the 1st period which applies a high frequency voltage, so that the measured resistance value is large. In order to perform this control, the voltage control unit 83 stores, for example, a third control table in which the resistance value range is associated with the first period.
FIG. 7 shows an example of the third control table. In the example of FIG. 7, the first period of “Trf1”, “Trf2”, and “Trf3” (Trf1 <Trf2 <Trf3) falls within the resistance value ranges of “less than R31”, “R31 or more and less than R32”, and “R32 or more”. ) Are associated.

  When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies a high-frequency voltage during the first period associated with the resistance value range including the measurement result in the third control table. . Thereby, the voltage control part 83 lengthens the 1st period (period which applies a high frequency voltage), so that the resistance value measured as mentioned above is large. In this case, in a situation where the inside of the skin is difficult to warm, the deep thermal effect is enhanced by lengthening the first period.

  For example, if it is difficult to warm the inside of the skin even when a high-frequency voltage is applied at the maximum, the deep layer thermal effect can be enhanced by lengthening the first period. On the other hand, if the inside of the skin gets too warm even when a high frequency voltage is applied at a minimum, the deep layer thermal effect can be suppressed by shortening the first period. In addition, even when the first period is changed, as in the case of changing the high-frequency voltage, the magnitude of the current flowing through the skin due to the difference in the individual conditions of the skin, the state of the skin, the type of the lotion, etc. A difference can be made small and the temperature difference inside skin (namely, the difference of a deep layer thermal effect) can be made small.

Moreover, the voltage control part 83 lengthens the 2nd period which applies a pulse voltage, so that the measured resistance value is large. In order to perform this control, the voltage control unit 83 stores, for example, a fourth control table in which the resistance value range is associated with the second period.
FIG. 8 shows an example of the fourth control table. In the example of FIG. 8, a first period of “Tp1”, “Tp2”, and “Tp3” (Tp1 <Tp2 <Tp3) is within the resistance value ranges of “less than R41”, “R41 or more and less than R42”, and “R42 or more”. ) Are associated.

  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 resistance value range including the measurement result in the fourth control table. . Thereby, the voltage control unit 83 lengthens the second period (period in which the pulse voltage is applied) as the resistance value measured as described above increases. In this case, in a situation where dirt or the like is not easily adsorbed to the cotton 70, the effect of deriving ions is enhanced by extending the second period.

  For example, when dirt or the like is not sufficiently adsorbed to the cotton 70 even when the pulse voltage is applied at the maximum, the effect of deriving ions can be enhanced by extending the second period. In addition, even when the second period is changed, as in the case of changing the pulse voltage, the magnitude of the current flowing through the skin due to the difference in the individual conditions of the skin, the state of the skin, the type of the lotion, and the like. The difference can be reduced to reduce the difference of dirt adsorbed on the cotton 70 (that is, the difference in ion derivation effect).

  The first to fourth control tables are not limited to those shown in FIGS. For example, the resistance value range may be two, or four or more. Further, each of the above controls may be performed using a relational expression between the resistance value, the high frequency voltage, the pulse voltage, and the first period or the second period. In short, any method may be used as long as the resistance value is increased, the high-frequency voltage can be increased, the pulse voltage can be increased, the first period can be lengthened, or the second period can be lengthened.

The face device 1 performs voltage control processing for controlling the high-frequency voltage and the pulse voltage based on the above configuration.
FIG. 9 shows an example of the operation procedure of the facial device 1 in the voltage control process. This operation procedure is started when an operation for starting the operation with the operation mode of the facial device 1 set to the cleansing mode is performed. First, the facial device 1 (the first power supply unit 81 or the second power supply unit 82) starts applying either a high-frequency voltage or a pulse voltage (step S10). It is initiated from either the voltage may be determined in either advance or may be a person who has been applied to the last time.

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

  Next, the facial beauty apparatus 1 (voltage control unit 83) determines whether or not the measurement interval has elapsed (step S21), and if determined that it has elapsed (YES), returns to step S11 (resistance value measurement). Perform the operation. If the facial beauty apparatus 1 (voltage control unit 83) determines that it has not elapsed (NO), the application period (the first period when the current high frequency voltage is applied, the first period when the pulse voltage is applied) It is determined whether or not (second period) has elapsed (step S22).

  When it is determined in step S22 that the time has not elapsed (NO), the facial beauty device 1 (voltage control unit 83) returns to step S21 (determination of measurement interval elapses) to perform the operation, and determines that it has elapsed (YES). In this case, the type of voltage to be applied is changed (if a high frequency voltage is currently 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 beautiful face device 1 (voltage control unit 83) returns to step S21 (determination of measurement interval elapse) after step S23 and operates.

  In this example, by controlling the high-frequency voltage and pulse voltage as described above, the difference in the magnitude of the current flowing through the skin due to individual differences in the skin, the state of the skin, the type of skin lotion, etc. It is made small to reduce the difference in the deep layer thermal effect and the effect of deriving ions. Thus, according to the present Example, the fluctuation | variation of the effect (the deep layer thermal effect and the ion derivation effect) of the beauty treatment when the situation changes can be reduced.

  Further, in this embodiment, cleansing by ion derivation is performed while warming the inside of the skin by alternately applying a high-frequency voltage and a pulse voltage. As described above, since the current flows more easily as the inside of the skin is warmed, in this embodiment, the effect of ion derivation can be enhanced by performing the deep layer heating simultaneously as compared with the case where only the pulse voltage is applied.

  In this embodiment, the cotton 70 is fixed by being attracted by the magnet portion 41 provided on the stopper 40 by the ring 60 that is a magnetic body. In a state where the head unit 10 is pressed against the user's skin, the magnetic force generated by the magnet unit 41 passes through the ring 60 and reaches the skin. As a result, force is applied to the ions in the blood component to activate the movement of the ions and promote blood circulation. In the facial device 1, by utilizing the mechanism for fixing the cotton 70 (the magnet unit 41 and the ring 60) for blood circulation promotion, the device can be reduced in size as compared with the case of using them in another mechanism. .

[2] Modifications The above-described embodiments are merely examples of the present invention and may be modified as follows. Moreover, you may implement combining the Example and each modification which were mentioned above as needed.

[2-1] Frequency Control In the above embodiment, the voltage control unit 83 controls the high frequency voltage, but the frequency of the high frequency voltage may be controlled. In this case, the voltage control unit 83 increases the frequency of the high frequency voltage as the measured resistance value increases. The voltage control unit 83 may perform this control using the control table described with reference to FIG. 5, or may perform this control using a relational expression between the resistance value and the frequency of the high frequency voltage.

  It is known that the higher the frequency of the high-frequency voltage, the faster the temperature inside the skin rises. Therefore, even when the frequency of the high frequency voltage is controlled as in the present modification, the individual differences in skin, the state of the skin, the type of skin lotion, and the like, as in the case of controlling the high frequency voltage in the example of FIG. The difference in the magnitude of the current flowing through the skin due to the difference can be reduced, the temperature difference inside the skin (that is, the difference in deep thermal effect) can be reduced, and the inside of the skin can be heated excessively. It can also be prevented.

[2-2] Object of voltage control In the above embodiment, the voltage control unit 83 performs all of the control of the high frequency voltage, the control of the pulse voltage, the control of the first period, and the control of the second period. At least one control may be performed. In addition, the second power supply unit 82 applies the above-described DC voltage instead of the pulse voltage, or applies the AC voltage with the polarity reversed, and the voltage control unit 83 controls these voltages. Also good. Moreover, you may combine the control of the frequency of the high frequency voltage described in the said modification. By controlling at least one of the high-frequency voltage, the frequency of the high-frequency voltage, or the first period, it is possible to reduce the fluctuation of the deep layer thermal effect. By controlling any one of the two periods, the fluctuation of the ion derivation effect can be reduced.

[2-3] Target for beauty treatment In the above-described embodiment, a facial device, which is an instrument that mainly performs a beauty treatment on a user's face, has been described. However, the present invention is not limited thereto, and for example, a user's arm, torso, leg, or the like. You may apply to the beauty processing apparatus which performs a beauty treatment to other parts.

[2-4] Porous Covering Body In the above examples, cotton 70 formed from cotton fibers in a sheet shape was used as the porous covering body and covered on the bottom surface 31 of the columnar part 30, but not limited thereto, For example, what formed other kinds of fibers, such as hemp and silk, in the shape of a sheet may be used as a porous covering. In short, any porous material can be used as long as it has a softness that can be applied to the bottom surface 31 of the columnar portion 30, penetrates the skin lotion, and adsorbs dirt when pressed against the skin. A quality coating may be used.

[2-5] Ion Introduction In the above embodiment, the pulse voltage is applied so that the second power supply unit 82 derives ions. However, the pulse voltage is applied so as to introduce ions while reversing the polarity of the voltage. May be. In this case, the skin lotion charged with negative ions is easily adsorbed and permeated into the skin. In addition, since the skin is warmed to the inside by the deep layer heat and the cells are activated, the lotion is more easily penetrated.

[2-6] Operation mode In the above-described embodiment, the facial device 1 is operated in the cleansing mode. However, the present invention is not limited to this. For example, the facial device 1 may be operated in the above-described ion introduction mode while performing deep layer heating. You may operate | move in the mode which performs only deep layer heat, the mode which performs only dirt removal, and the mode which performs only ion implantation.

[2-7] Direct contact with skin In the above embodiment, the facial device 1 is used in a state where the bottom surface 31 of the columnar portion 30 is covered with the cotton 70, but is used in a state where the cotton 70 is not covered. May be. In that case, the resistance value is measured in a state in which the first electrode and the second electrode are in direct contact with the user's skin by operating the facial device 1 in a mode in which only the above-described deep layer heating is performed, for example, and the measured resistance value Since the high-frequency voltage corresponding to is applied, the variation of the deep layer thermal effect when the situation such as the skin condition changes can be reduced as in the embodiment.

[2-8] First Electrode In the above embodiment, the first electrode has an annular shape with an opening at the center, but may have a disk shape with no opening at the center. Even in that case, since the distance between the first electrode and the second electrode is constant anywhere on the circumference, the heat generation area of the user's skin can be widened, and stimulation by energization can be made uniform.

[2-9] Electrode part In the said Example, although the electrode part was provided with the 1st electrode and the 2nd electrode of the annular shape both, it is not restricted to this. The electrode unit may include, for example, a polygonal and annular first electrode and second electrode, or may include a rod-shaped first electrode and second electrode arranged in parallel. In any of the shapes, it is desirable that the number of portions where the distance between the first electrode and the second electrode is the shortest distance is greater because a high-frequency current can be made to flow in a wide range and evenly.

[2-10] Resistance Value In the above embodiment, the resistance measurement unit 84 measures the electrical resistance (resistance) as the resistance value between the first electrode 21 and the second electrode 22, but is not limited to this. The reactance between the electrode 21 and the second electrode 22 may be measured as a resistance value. In short, a value representing the difficulty of current flow between the first electrode 21 and the second electrode 22 may be measured as the resistance value. Note that a value representing the ease of current flow, such as conductance, can also be treated as a resistance value because it represents the difficulty of current flow if the reciprocal is used.

[2-11] Method of Measuring Resistance Value In the above embodiment, the resistance measuring unit 84 is supplied with the first electrode 21 and the second electrode by the current that flows when a high frequency voltage is applied between the first electrode 21 and the second electrode 22. Although the resistance value between the electrodes 22 was measured, the method of measuring the resistance value is not limited to this. For example, the resistance measuring unit 84 is configured to generate the first electrode 21 and the first electrode 21 by a current that flows when a measurement voltage (for example, a DC voltage) for measuring a resistance value is applied between the first electrode 21 and the second electrode 22. The resistance value between the two electrodes 22 may be measured.

  In this case, for example, before the first power supply unit 81 applies the high-frequency voltage for the deep layer heating, first, the measurement voltage is applied and the resistance measurement unit 84 measures the resistance value, and the high resistance according to the measured resistance value. When the voltage control unit 83 performs control so that the high-frequency voltage and the pulse voltage are applied, the difference in the magnitude of the current flowing through the skin can be determined at the start of the cosmetic treatment compared to the case where this control is not performed. Can be made smaller. In addition, the resistance measuring unit 84 may be provided with another pair of electrodes on the bottom surface 31 of the columnar unit 30 to measure a resistance value therebetween, or a sensor that outputs a value indicating electric resistance to the bottom surface 31. And the resistance value may be measured using the output value.

  In short, the resistance value may be measured by any method as long as it is an index of the ease of current flow in the portion of the user's skin where the head unit 10 is pressed. In addition, when the resistance measurement part 84 measures the resistance value between the 1st electrode 21 and the 2nd electrode 22 like an Example, since it is not necessary to provide another electrode or sensor, compared with the case where they are provided. Thus, the device can be miniaturized.
