  Conventional beauty devices are configured as described in the above patent documents, and among such devices that perform iontophoresis, in combination with iontophoresis, warm the skin, emit ultrasonic waves to the skin, light Have been proposed, but the relationship between these other cosmetic operations and iontophoresis has not been clarified, and it is assumed that each function is simply executed at the same time. There is no concrete description of the combination structure of the ion introduction mechanism and the mechanism that realizes other functions to the extent that it is feasible, and it remains at the concept stage.

  In particular, in the case of applying heat at the same time as ion introduction, a heater that generates heat by energization is indispensable for efficient heating at low cost for introduction to home use. As a feasible configuration that does not cause a contradiction such as a short circuit or malfunction, a simple connection mechanism, an electrical connection mechanism of a heater that heats the electrode for applying heat, and a heat transfer structure between the heater and the electrode What is specifically shown does not yet exist, and has a problem that a beauty device having a simple and low-cost heating mechanism cannot be practically used.

  The present invention has been made to solve the above-described problems, and the mechanism for applying heat to the skin can be configured simply and consistently with other mechanism parts in terms of electrical and heat transfer, and appropriately heated. It is an object of the present invention to provide a beauty device capable of producing an imparted state and obtaining an excellent beauty effect.

  A cosmetic device according to the present invention is a cosmetic device that performs a predetermined cosmetic operation on a user's skin, and is disposed at a body portion held by the user and one end portion of the body portion, and has thermal conductivity. A head portion formed of a material having a heater disposed in the main body portion and heated by energization, and a heat transfer member interposed between the heater and the head portion, and the head portion is at or above a human body temperature. And a control unit that adjusts and controls the heating state of the head unit by the heating unit. The heater of the heating unit has two substantially parallel surfaces, and the two surfaces are positive and negative for energization. Each terminal is electrically connected to each other, and is disposed in close proximity to the heat transfer body via the terminal on one of the two surfaces, pressed to the heat transfer body side by a predetermined biasing means, and the heat transfer body, It is formed of a substantially sheet-like body that has good thermal conductivity and is elastically deformable. Than is.

  As described above, according to the present invention, the head portion disposed at one end portion of the main body portion and brought into contact with the user's skin can transmit heat from the heater forming the heating portion in the main body portion via the heat transfer body. The heater is pressed against the heat transfer body side, the heater is pressed against the terminal, the terminal is pressed against the heat transfer body, and the elastically deforming heat transfer body is in close contact with the terminal and the head portion without any gaps. Is transmitted to the head part through the terminal and heat transfer body without any loss, so that the electrical connection for energizing the heater and the heat conduction structure between the head part and the heater are compatible with each other. The heater can be efficiently heated by the heater, and the temperature control state of the heater can be reflected smoothly and smoothly on the head portion. And the heat is applied to the skin. The Azukasuru structure can be low-cost.

  In addition, the beauty device according to the present invention is provided in the vicinity of the head part of the main body part and the auxiliary electrode part for ion introduction provided in the grip part by the user of the main body part, if necessary. A porous coating body that can be impregnated with a liquid for introduction is detachably held on the head portion, and the head portion is formed of a conductive material to serve as an ion introduction electrode. The heat transfer body is electrically insulative and transmits heat of the heater to the head part while insulating the heater and the head part, and the control part is configured to transmit the heat between the head part and the auxiliary electrode part. Electricity can be passed through the porous coating body and the user, and ion introduction into the skin is caused from the cosmetic impregnated in the porous coating body while heating the head section by the heating section.

  As described above, according to the present invention, the head portion is an ion introduction electrode, and a current flows during the ion introduction. On the other hand, the heater and the terminal are connected via the heat transfer body having an electrical insulation property. Heat is transferred from the heater to the head while the electrical wiring for energizing the head is electrically isolated from the heater by the heat transfer body so that heat is transferred between the head and the head. By realizing conduction, it is possible to properly execute the energization of the head part for ion introduction and the heating of the head part by the heater without adversely affecting each other. Even if it is changed accordingly, there is no effect on the heater independent of the electrical wiring of the head part, and there is no problem even if the head part is energized and heated at the same time. ion Can be carried out synchronously, and can promote ion introduction by warming the skin and iontophoretic cosmetics to increase permeability, enabling ion introduction to the skin extremely efficiently and exerting a cosmetic effect .

  Further, in the beauty device according to the present invention, if necessary, the control unit impregnates a cosmetic for wiping between the head unit and the auxiliary electrode unit in a state where the heating unit does not heat the head unit. In addition, a cleansing mode is provided in which electricity is passed through the porous coating body and the user, the charged dirt component in the skin is moved to the head portion side, and the dirt component is taken into the porous coating body.

  As described above, according to the present invention, a current is passed through the user's skin using the head part as an electrode, and the charged dirt component on the skin is moved toward the head part side as an electrode for cleansing, and the dirt component is removed. By performing the action of taking it into the porous coating and removing it from the skin, it is possible to realize a new function without affecting the operation of the heater by energizing the head part in addition to the introduction of ions. Thus, it is possible to reliably remove the dirt of the skin that is difficult to remove, and to eliminate the adverse effect of the dirt on the skin and to further improve the effect of ion introduction into the skin as the dirt is eliminated.

  Further, in the beauty device according to the present invention, if necessary, the control unit maintains a heating temperature of the heating unit at a predetermined first temperature when the head unit is heated by the heating unit; There is a second period for maintaining the second temperature several times higher than the first temperature, and the second period is set to be longer than the first period after the first period. The heating of the head portion is repeatedly executed with a period for temporarily stopping the heating.

  As described above, according to the present invention, when the head unit is heated by the heating unit, after the heating temperature is maintained at the first temperature for a while, the temperature is increased to the second temperature and maintained for a while. Repeatedly, the entire heating period is mostly at the second temperature, with a period of time between the first temperature and the second temperature on the user's skin, sometimes in the middle of the first temperature in between. By making a temperature change feel, even if a thermal stimulus by a second temperature higher than the body temperature is given to the skin, if the temperature is constant, it becomes difficult to feel the stimulus as a normal reaction of the person as it was at the beginning In other words, habituation occurs, but the change to the first temperature is sometimes added, so that habituation is less likely to occur and changes to a state that promotes skin penetration as a response to thermal stimulation, blood circulation enhancement, etc. The event has given heat It occurs without change and, throughout while the skin is warmed in the head portion, can be given reliably cosmetic effect associated therewith.

  Further, in the beauty device according to the present invention, if necessary, the terminal disposed on the side opposite to the side close to the heat transfer body among the energizing terminals disposed with the heater interposed therebetween is the other. It is formed in the shape of a leaf spring in which the contact surface with the heater is smaller than the terminal, and also serves as the urging means.

  As described above, according to the present invention, among the terminals for energization in contact with the heater, the contact surface with the heater of the terminal disposed on the opposite side of the terminal close to the heat transfer body is formed, By making the amount of heat transferred from one side of the heater to the terminal close to the heat transfer body different from the amount of heat transferred from the other side of the heater to the terminal, the contact surface between the heater and the terminal has a larger heat transfer body side. Heat of the heater is easy to be transmitted and the heat of the heater can be efficiently transmitted to the head part via the terminal and heat transfer body, while the heat transmitted to the other terminal side where the contact surface between the heater and the terminal is small is the minimum necessary The movement of heat from the heater through the terminal to the inside of the main body can be suppressed, and adverse effects due to the heat inside the main body can be prevented without particularly arranging a heat insulating material or the like. In addition, the terminal plays the role of a leaf spring and also serves as a biasing means, so that the structure can be simplified, and it is not necessary to arrange a heat insulating material etc. for shutting off the heat from the heater in the main body part. Further cost reduction can be achieved.

  Hereinafter, a beauty apparatus according to an embodiment of the present invention will be described with reference to FIGS.

  In each of the drawings, the cosmetic device 1 according to the present embodiment is used for a cosmetic operation such as ion introduction to the skin (skin) 50, which is disposed at the tip of the main body 11 and the main body 11 held by the user. A head unit 12, a heating unit 13 disposed in the main body unit 11 for heating the head unit 12, a tilting arm unit 14 disposed in a tiltable manner in a predetermined part of the main body unit 11 near the head unit 12, An irradiation unit 15 that is attached to the tilting arm unit 14 and emits light of a predetermined wavelength, and a pair of roller electrodes 16 and 17 that are rotatably disposed at the tip of the tilting arm unit 14 with the irradiation unit 15 interposed therebetween. And a control unit 18 that controls energization of each electrode and light irradiation in the irradiation unit 15, and a holding unit 19 that holds the porous covering 12 a with respect to the head unit 12.

  The main body 11 has the head portion 12 disposed at one end, and a grip portion 11a that is held and held by a user during use at the other end. The longitudinal direction of the grip portion 11a And the front direction of the head part 12 are formed in a shape inclined by a predetermined angle, and an electric circuit such as the control part 18 and a battery (not shown) as a power source are arranged inside. Further, the tilting arm portion 14 can be attached in the vicinity of the head portion 12 of the main body portion 11.

  In addition, on the front side of the gripping part 11a close to the front side of the head part 12, an operation part 11b for switching the cosmetic operation ON / OFF, operation type, strength, etc. in response to a user's input operation is disposed. An auxiliary electrode portion 11c made of a conductive member and connected to the control portion 18 is disposed on the side surface of the grip portion 11a.

  Furthermore, the vicinity of the head part 12 in the main body part 11 is formed in a shape in which a holding part 19 for holding the porous covering 12a can be attached.

  The holding portion 19 is an annular body formed of a material having resilience with respect to an external force, and is configured to be integrated with the main body portion 11 by engaging with the periphery of the head portion 12 in the main body portion 11. . When the holding portion 19 is directly engaged with the main body portion 11 in a state where the porous covering body 12a is sandwiched between the holding portion 19 and the main body portion 11, the porous covering body 12a together with the holding portion 19 becomes the main body. In this mechanism, the porous cover 12a is not easily detached from the portion 11 and can be held in a state where the porous covering 12a is positioned on the head portion 12. The holding portion 19 is formed as a separate body from the main body portion 11, but is not limited to this, as long as the porous covering body 12 a can be held by pressing along the head portion 12. A structure integrated with the main body 11 from the beginning may be used.

  The head portion 12 is made of a material having conductivity and good thermal conductivity, such as metal, and is in contact with the skin 50 directly or via the porous coating 12a, and cosmetic operations such as ion introduction to the skin 50. Is to execute. The head unit 12 is electrically connected to the control unit 18 through the spring 12b, the lug terminal 12c, the conductive wire 12d, and the like in the main body unit 11, and is connected to the auxiliary electrode unit 11c in the holding unit 11a. It is the structure which can be supplied with electricity through the body. Further, the heating unit 13 is in contact with the head unit 12 from the inside of the main body unit 11 and is heated by the heating unit 13 as necessary to raise the temperature to a predetermined temperature equal to or higher than the body temperature. However, there is no electrical connection between the head unit 12 and the heating unit 13, and the energization wiring to the head unit 12 including the spring 12b and the wiring to the heating unit 13 are independent. Yes.

  For energization, a voltage is applied between the head unit 12 and the auxiliary electrode unit 11c by the control unit 18 so that energization can occur, and then a lotion, an emulsion, a gel, a cream or the like containing an electrolyte component is used. When the head portion 12 comes into contact with the skin 50 such as the face or the auxiliary electrode portion 11c comes into contact with a palm or a finger having the grip portion 11a through the porous covering 12a impregnated with the cosmetic. The head unit 12 and the auxiliary electrode unit 11c are energized through the user's body. In this case, the human body becomes a conductor.

  The head portion 12 and the auxiliary electrode portion 11c are sufficiently separated from each other, so that a hand or the like touching the auxiliary electrode portion 11c is not in contact with the head portion 12 and no current is generated.

  In the cosmetics such as lotion, milky lotion, gel agent, cream agent or the like that has been applied to the skin surface in advance with the energization of the skin 50 that is in contact with the head portion 12 or has been impregnated into the porous covering 12a. This is a mechanism capable of executing ion introduction (iontophoresis) for introducing the contained ionic active ingredient into the skin by ion movement based on the current from the control unit 18. Since the ion introduction method itself is known, a detailed description thereof will be omitted.

  Further, as a cleansing, it is possible to obtain a state in which a dirt component such as a charged waste product is transferred from the skin side to the head portion 12 side by energization and is taken into the porous covering body 12a.

  The size of the head portion 12 is an appropriate size, and the head portion 12 is brought into contact with a concave portion such as a boundary portion of the nose and cheeks in the skin 50 with which the head portion 12 is brought into contact. Even in such a case, it is possible to reliably contact with a contact surface having an appropriate size, and ion introduction and cleansing can be performed without deviation.

  The head portion 12 is desirably made of a material that is stable with respect to energization, such as titanium, in terms of ion introduction and the like. That is, if the head part 12 is made of a plating surface such as chromium, metal ions are eluted on the surface of the head part 12 by electrolysis when ions are introduced, and the eluted metal ions have an adverse effect on the skin. However, if titanium having high stability is used on the electrode surface, metal ions of titanium are not eluted by electrolysis in the head portion 12 even when energized, and can be used safely. The electrode surface material is preferably pure titanium, but may be a titanium compound. In addition to titanium, gold can also be used.

  In addition, when the head portion 12 is covered with the porous coating body 12a soaked with cosmetics such as lotion by ion introduction, the tilting arm portion 14 is tilted to irradiate the irradiation portion 15 and The roller electrodes 16 and 17 are shifted from the front surface of the head portion 12 so that the porous head 12 is covered with the porous cover 12a and the holding portion 19 is fitted to fix the porous cover 12a.

  The porous covering 12a is used as a cover for covering the head part 12 by forming cotton fibers processed by degreasing, such as cut cotton or cotton puff, into a non-woven sheet, and is used as a cover for skin lotion, emulsion, gel It has the property of sufficiently absorbing and retaining cosmetics such as creams. In addition, as long as this porous coating | coated body 12a is a porous soft sheet-like thing which can be impregnated with cosmetics and has flexibility, things other than cotton can also be utilized.

  The heating unit 13 is configured to heat the head unit 12 to a predetermined temperature so that the head unit 12 can apply heat to the cosmetics soaked in the skin 50 and the sheet. 12, a heater 13a that generates heat when energized, a large terminal portion 13b that is disposed in contact with a surface near the head portion 12 of the heater 13a, and a surface side away from the head portion 12 of the heater 13a. Between the heater 13a, the large terminal portion 13b, and the head portion 12, and between the heater 13a, the large terminal portion 13b, and the head portion 12. A heat transfer body 13d capable of conducting heat from the heater 13a side to the head portion 12 side while maintaining insulation, a temperature sensing body 13e disposed near the heater 13a for detecting the temperature of the heater, the heater 13a, Each terminal A structure and a holder portion 13f which it supports.

  The heater 13a is a so-called PTC (Positive Temperature Coefficient) heater, which has a positive temperature coefficient and is prepared to have a resistance change characteristic in which the resistance value increases rapidly at a certain temperature (Curie temperature) when the temperature rises. It is formed as a thin disk shape made of a ceramic or organic material, and is energized by bringing the large terminal portion 13b and the small terminal portion 13c into contact with each circular surface, and the temperature is raised to a preset temperature by the control unit 18. It is something to warm. The heater itself has a self-temperature control function, is reliable and has a long life, and the heater capacity is constant up to the set temperature, so that the set temperature can be reached quickly.

  The heater 13a is controlled by the control unit 18 so as to cause a temperature change with the passage of time. For example, the temperature rises to a predetermined temperature higher than the body temperature, for example, 44 ° C. in about 30 seconds from the start of energization. The temperature is maintained at a temperature of 2 ° C., and the temperature is further increased to reach 48 ° C., for example, 48 ° C., and this 48 ° C. is controlled for 1 minute. And while heating of the head part 12 by the heater 13a is required, the control which produces the said temperature change is performed repeatedly.

  The large terminal portion 13b is formed of a thin metal plate, and is in contact with substantially the entire circular surface near the head portion 12 of the heater 13a so as to be energized, and is also in contact with the heat transfer body 13d and is generated in the heater 13a. Heat is transferred to the head unit 12 side.

  The small terminal portion 13c is made of a thin metal plate and is partially formed as a leaf spring. The small terminal portion 13c is in contact with a portion of a circular surface separated from the head portion 12 in the heater 13a, and can be energized. 13a is pressed toward the large terminal portion 13b side (head portion 12 side). In detail, it is a structure provided with the substantially circular part of a center, and the leaf | plate spring part extended and arrange | positioned in the three directions which become radial on the outer peripheral part at equal intervals.

  The three leaf spring portions in the small terminal portion 13c extend in a floating state without being in contact with the heater 13a, and only the end portion is in contact with the holder 13f, whereby the entire small terminal portion 13c is supported. Thus, heat is transmitted from the small terminal portion 13c to the holder 13f side as much as possible.

  On the other hand, since the central circular portion that is the contact surface with the heater 13a in the small terminal portion 13c is smaller than the large terminal portion 13b, the heat generated in the heater 13a is easily transmitted to the large terminal portion 13b side. Is a mechanism that mainly travels through the large terminal portion 13b and reaches the head portion 12 via the heat transfer body 13d.

  Further, due to the difference in contact area, the heat transmitted from the heater 13a to the small terminal portion 13c is small, and the small terminal portion 13c having a leaf spring portion creates a space between the heater 13a and the holder 13f, thereby the main body. The amount of heat transmitted to the inside of the portion 11 can be kept small.

  The heat transfer body 13d is a disk-like member made of an elastically deformable electrical insulating material and a material having excellent thermal conductivity, and is interposed between the large terminal portion 13b and the head portion 12, respectively. And heat from the large terminal portion 13b side is reliably transmitted to the head portion 12 side. The small terminal portion 13c presses the heater 13a toward the large terminal portion 13b with its spring property, so that the heater 13a is in close contact with the large terminal portion 13b, and the large terminal portion 13b pushed by the heater 13a becomes the heat transfer body 13d. The large terminal portion 13b presses the heat transfer body 13d and partially elastically deforms, whereby the large terminal portion 13b can be in close contact with the heat transfer body 13d and is pressed by the large terminal portion 13b. Since the heat transfer body 13d can also be in close contact with the head portion 12, the heat from the surface of the heater 13a is transmitted to the head portion 12 side without deviation.

  On the other hand, since the heat transfer body 13d wider than the large terminal portion 13b has an insulating property and isolates the large terminal portion 13b from the head portion 12, electrical connection between the large terminal portion 13b and the head portion 12 is achieved. Therefore, no short circuit or other adverse effects can be prevented between the heating circuit and the energization circuit to the head portion 12.

  Further, there is an upright wall portion 11g arranged in a state of surrounding the heater 13a, the large terminal portion 13b, and the small terminal portion 13c of the heating unit 13 and has electric insulation. The heater 13a, the large terminal portion 13b, and the small terminal portion 13c are disposed on the inner wall portion partitioned by the heat transfer body 13d and the standing wall portion 11g made of a material that does not easily transfer heat. In addition to electrically separating the energizing wires such as springs 12b and lug terminals 12c connected to the head portion 12 from the outside and the heating portion 13, heat escapes to the main body portion 11 side outside the section. Can be suppressed. And since the small terminal part 13c has located the heater 13a in the inner part upper part of this division, the space is also produced and it is the mechanism which can further suppress the escape of the heat | fever from the heater 13a to the inside of the main-body part 11. FIG.

  The tilting arm portion 14 is a substantially arm-like member that is attached to a tip portion of the main body portion 11 with the head portion 12 so as to be tiltable, and the irradiation portion 15 and the roller electrodes 16 and 17 are disposed at end portions away from the center of tilting. It is the structure which can be attached. For the tilting arm portion 14, when a light source with a wide light irradiation range is used as the irradiation portion 15, the irradiation portion 15 is used to prevent unexpected leakage of light from other than the opening portions sandwiched between the roller electrodes 16 and 17. It is preferable to make it the shape which covers the side of.

  When energization and light irradiation are performed by the roller electrodes 16 and 17, the tilting arm portion 14 is tilted so that the irradiation portion 15 and the roller electrodes 16 and 17 are positioned in front of the head portion 12, and the roller electrodes 16 and 17 are placed on the skin 50. It is in a state where it can abut. On the other hand, when energization and light irradiation by the roller electrodes 16 and 17 are not performed, such as ion introduction, the tilting arm portion 14 is tilted to shift the irradiation portion 15 and the roller electrodes 16 and 17 from the front of the head portion 12, and the head portion. 12 will be in an open state and will be in a state where it can contact the skin 50.

  The irradiation unit 15 is a known light source in which a plurality of high-intensity light-emitting diodes (LEDs) that emit light such as infrared light and visible light that cause a predetermined treatment effect on the skin 50 are arranged. Omitted. The irradiation unit 15 is electrically connected to the control unit 18 inside the main body 11 through a conducting wire provided in the tilting arm unit 14.

  The roller electrodes 16 and 17 are conductors arranged in a pair so as to be able to come into contact with the skin 50 on the tip side away from the tilting center portion of the tilting arm portion 14 and to face each other with the irradiation portion 15 interposed therebetween. In the state where the electrode forming the skin 50 and the skin 50 are in contact with each other, the control unit 18 makes the pair of electrodes energized. The roller electrodes 16 and 17 may be formed of a conductor such as metal, or may have a structure in which a conductor such as metal is attached to a surface of an elastic body such as rubber or a thin film of conductor is disposed. The roller electrodes 16 and 17 are also electrically connected to the control unit 18 inside the main body 11 through a conducting wire provided in the tilting arm unit 14, similarly to the irradiation unit 15.

  The control unit 18 is built in the main body unit 11 and receives an input operation to the operation unit 11b of the user, and energizes between the head unit 12 and the auxiliary electrode unit 11c, heating the head unit 12 by the heating unit 13, The energization between the paired roller electrodes 16 and 17 and the light irradiation of the irradiation unit 15 are respectively controlled.

  The control unit 18 sets an operation mode for each cosmetic application. In this embodiment, the cleansing mode removes harmful components and waste products accumulated in the skin, and penetrates the active ingredients of cosmetics deep into the skin. There are four modes: an iontophoresis mode to activate, a roller energization and light irradiation mode for activating the skin to fix emulsion and cream, and a penetration mode, and a heating mode for enhancing the massage effect by applying thermal stimulation to the skin.

  In the cleansing mode, roller energization, and light irradiation mode, the heating of the head unit 12 by the heating unit 13 is not performed. In the cleansing mode and the iontophoresis mode, the head portion 12 and the auxiliary electrode portion 11c are energized. In the roller energization and light irradiation mode, the energized state is set between the paired roller electrodes 16 and 17. Moreover, light irradiation by the irradiation unit 15 is executed only in the roller energization and light irradiation modes. In the heating mode, only heating of the head unit 12 by the heating unit 13 is performed, and energization between the electrodes is not performed.

  This switching of the operation mode is performed based on a user input operation to the mode switch 11d and the heating switch 11e of the operation unit 11b. When the user first operates the mode change switch 11d immediately after the power is turned on, the control unit 18 is in a state where it can execute any one of the cleansing mode, the ion introduction mode, the roller energization mode, and the light irradiation mode, and first, the heating switch 11e. When is operated, the heating mode is executed. When the heating switch 11e is operated after selecting the operation mode by operating the mode switch 11d, if the ion introduction mode is selected, the head unit 12 is heated and heat is added in parallel with the ion introduction. However, if the cleansing mode, the roller energization and the light irradiation mode are selected, these operations and heating of the head unit 12 are not performed simultaneously, and the operation of the heating switch 11e is invalidated. On the other hand, when the heating switch 11e is operated again while the head unit 12 is being heated by operating the heating switch 11e, the heating of the head unit 12 is stopped.

Further, the control unit 18 controls the heat generation state of the heater 13 a based on the temperature detected by the temperature sensing element 13 e for the heating unit 13 and adjusts the temperature of the head unit 12. When heating the head unit 12, the heating state in the heating unit 13 is controlled so as to cause a temperature change in the head unit 12 in order to prevent the user from getting used to the thermal stimulation from the head unit 12. That is, changing the temperature at a predetermined timing does not cause the user to become accustomed, and the user always receives the heat as a stimulus that does not change from the original, and the effect of the heat is not impaired. The control unit 18 raises the heater temperature of the heating unit 13 that heats the head unit 12 to a first temperature, for example, 44 ° C. for a short period of time after the start of heating, for example, about 30 seconds. After maintaining the first period, for example, close to 30 seconds, the temperature is further raised several times to a second temperature, for example 48 ° C., and this second temperature is set to a second period longer than the first period, for example 2 After continuing for about a minute, a series of temperature control states in which the heating state is stopped and the heater 13a and the head unit 12 are in a natural heat radiation state are repeatedly executed at predetermined time intervals.

  Next, each cosmetic operation state of the beauty device according to the present embodiment will be described. As a premise, the beauty device 1 is activated by the user operating the power switch 11f of the operation unit 11c, and the user holds the grasping unit 11a so that the head unit 12 or the roller electrodes 16 and 17 are directed to the skin site to be used. It shall be. When the operation mode is selected and input by the user, the control unit 18 enters a state in which execution of each operation mode can be started.

  When performing cleansing, the user tilts the tilting arm part 14 in advance to shift the irradiation part 15 and the roller electrodes 16 and 17 from the front of the head part 12 so that the head part 12 can be brought into contact with the skin, Cover the head portion 12 with a porous covering 12a soaked with cosmetics such as a wiping lotion containing an electrolyte component, and fix the porous covering 12a by fitting the holding portion 19 into the main body 11. To do.

  When the user operates the mode selector switch 11d of the operation unit 11b to select the cleansing mode, the control unit 18 starts the energization state in which a pulsed weak current is passed between the head unit 12 and the auxiliary electrode unit 11c in a short cycle. Make it possible. However, in the state where the head part 12 is separated from the skin, since the circuit between the head part 12 and the auxiliary electrode part 11c is not closed through the body, there is no energization. In this cleansing mode, the head unit 12 is not heated by the heating unit 13.

  When the head portion 12 is brought into close contact with the skin 50 through the porous coating 12a, the body and the cosmetic material in the porous coating 12a are energized, and the skin surface and the inside are charged fine dirt components (spots). Cosmetic components, tobacco smoke components, aging keratin, etc. that were not present are attracted to the head portion 12 and transferred from the skin side to the porous coating body 12a, and dirt components are taken into the porous coating body 12a. By becoming a state, dirt on the skin can be removed by suction.

  If the head portion 12 is moved little by little on the skin while the porous covering 12a is in contact with the skin 50, the target position of dirt removal can be changed in the energized state, but this removal operation can be interrupted or removed. When the head portion 12 is separated from the skin 50 to change the power, the energization is immediately interrupted. When cleansing is completed completely, the user may switch the operation mode to another by using the operation unit 11b or turn off the power.

  After this cleansing is completed, the fitted holding portion 19 is removed, the porous covering 12a is removed, and the head portion 12 is cleaned. In addition, the user cleans the face and removes the dirt remaining on the skin.

  When ion introduction is performed, the user tilts the tilting arm portion 14 in advance as described above to displace the irradiation portion 15 and the roller electrodes 16 and 17 from the front of the head portion 12 so that the head portion 12 can be brought into contact with the skin. A porous coating 12a soaked with cosmetics such as protective lotion containing an electrolyte component is placed on the head portion 12, and the holding portion 19 is fitted to the main body portion 11 to form a porous coating. The body 12a is fixed. In this case, after covering the head 12 with the porous covering 12a and fitting and fixing the holding portion 19, the cosmetic may be soaked into the porous covering 12a.

  When the user operates the mode changeover switch 11d of the operation unit 11b to select the ion introduction mode, the control unit 18 starts an energized state in which a weak pulsed current flows between the head unit 12 and the auxiliary electrode unit 11c in a short cycle. Is possible. When the user operates the heating switch 11e as necessary, the control unit 18 starts heating the head unit 12 by the heating unit 13. However, in a state in which the head portion 12 is separated from the skin 50, since the circuit between the head portion 12 and the auxiliary electrode portion 11c is not closed, there is no energization.

  When the head portion 12 is brought into close contact with the skin 50 through the porous coating 12a, the body and the cosmetic in the porous coating 12a are energized, and the ions in the cosmetic are generated by the current flowing through the porous coating 12a. The active ingredient (such as provitamin C) is transferred to the skin side, and the active ingredient quickly penetrates into the skin where ions are easily penetrated by the current.

  At this time, when the head portion 12 is heated, the porous covering body 12a and the skin 50 are warmed by the head section 12 heated to an appropriate temperature by the heating section 13, whereby the porous covering body 12a. As the activity of the cosmetics in the skin increases, the skin 50 also changes to a state in which the active ingredients are easily penetrated, and the transition of the ionic active ingredients into the skin is further promoted. Water-soluble active ingredients and oil-soluble active ingredients are also easily penetrated into the skin 50, and these various active ingredients penetrate deep into the skin 50 and surely give a cosmetic effect.

  If the head portion 12 is moved little by little on the skin while being in contact with the skin 50 together with the porous covering 12a, the target position for ion introduction can be changed while being energized, but the ion introduction is interrupted or the introduction position is changed. When the head portion 12 is separated from the skin 50 in order to greatly change, the energization is immediately interrupted. When ion introduction is completed completely, the user may switch the function to another by the operation unit 11b or turn off the power.

  After completion of this ion introduction mode, the fitted holding portion 19 is removed, and the porous covering 12 a is removed from the head portion 12.

  When the roller energization and the light irradiation are performed, the user tilts the tilting arm portion 14 so that the roller electrodes 16 and 17 and the irradiation portion 15 are positioned on the front side of the head portion 12, and the roller electrodes 16 and 17 are on the skin 50. It is in a state where it can abut. At the same time, apply a lotion or cream to the skin and let it become familiar.

  When the user operates the mode changeover switch 11d of the operation unit 11b to select the roller energization and light irradiation mode, the control unit 18 energizes the pulsed weak current between the paired roller electrodes 16 and 17 in a short cycle. The state can be started, and light irradiation in the irradiation unit 15 is also started. However, in a state where the roller electrodes 16 and 17 are separated from the skin 50, since the circuit between the roller electrodes 16 and 17 is not closed via the body, there is no energization. In this roller energization and light irradiation mode, the head unit 12 is not heated by the heating unit 13, and the operation of the heating switch 11e is invalid.

  When the roller electrodes 16 and 17 are brought into close contact with the skin 50, the energized state is passed through the skin 50 between the paired roller electrodes 16 and 17, and the skin 50 is stimulated by energization, and the skin 50 is activated to activate an emulsion or cream. Will be promoted. In addition, the skin 50 receives light with an appropriate irradiation intensity from the irradiation unit 15, and a cosmetic effect by the light is also produced.

  When the roller electrodes 16 and 17 are rolled while being kept in contact with the skin 50 and are moved little by little on the skin, the energization and light irradiation target positions can be changed, but the energization is interrupted or the energization and irradiation positions are changed. Therefore, when the roller electrodes 16 and 17 are separated from the skin 50, energization between the roller electrodes is immediately interrupted. When the energization and irradiation are completely completed, the user stops the energization between the roller electrodes 16 and 17 and the irradiation of light in the irradiation unit 15 if the user switches the function to another in the operation unit 11b or turns the power off.

  In the case of performing massage accompanied by the application of heat to the skin, the user tilts the tilting arm portion 14 in advance to shift the irradiation portion 15 and the roller electrodes 16 and 17 from the front of the head portion 12, and the head portion 12 is placed on the skin 50. It is set in an open state where it can come into contact. At the same time, apply a massage cream to the skin. In this case, a cream having a pack effect is more preferable.

  When the user operates the heating switch 11e of the operation unit 11b to select the heating mode, the control unit 18 starts heating the head unit 12 by the heating unit 13. In this case, energization between the head unit 12 and the auxiliary electrode unit 11c is not performed.

  When the head part 12 whose temperature has been increased by the heating part 13 is brought into close contact with the skin 50, the skin and cream are warmed, and the user moves the main body part 11 while pressing the head part 12 against the skin 50. The skin 50 is massaged by the part 12, and the skin is warmed while being massaged over the entire cream application part.

  Control of the heating unit 13 causes the head unit 12 not to be at a constant temperature but to undergo a predetermined temperature change, so that the skin 50 does not get used to the thermal stimulation and does not slow down the response to the thermal, and the thermal is surely stimulated. It can be changed to a state in which the skin is easily absorbed.

  In the case of a cream having a pack effect, the active ingredient in the cream smoothly penetrates into the warmed and easily penetrated skin 50, and the beauty effect can be further enhanced.

  When the cream is sufficiently warmed by the heat and body temperature from the heating unit 13 and the stirring of the cream accompanying the stimulation of the massage proceeds, the liquidity of the cream changes to shift to a phase inversion state indicating the end of the massage. 12 is released from the skin 50, and the user operates the heating switch 11e of the operation unit 11b to stop heating or turn off the power to complete the massage completely. And a user will wash away cream from skin.

  As described above, in the beauty device according to the present embodiment, the head portion 12 that is disposed at one end portion of the main body portion 11 and serves as an ion introduction electrode has a heater 13 a that forms the heating portion 13 in the main body portion 11. Heat is transmitted through the heat transfer body 13d having electrical insulation, and the heater 13a is pressed toward the heat transfer body 13d to heat the heater 13a to the large terminal portion 13b and the large terminal portion 13b to the heat transfer body 13d. The heat transfer body 13d, which is pressed and elastically deformed, is brought into close contact with the large terminal portion 13b and the inner surface of the head portion 12 by pressing, so that the heat of the heater 13a passes through the large terminal portion 13b and the heat transfer body 13d. Therefore, the heater 13a efficiently combines the electrical connection for energizing the heater 13a and the heat conduction structure between the head portion 12 and the heater 13a without any contradiction. 12, the temperature control state of the heater 13 a can be reflected smoothly and smoothly on the head portion 12, and heat can be appropriately applied to the skin, and the temperature rise state of the head portion 12 can be obtained with a simple mechanism. In addition, the structure for applying heat to the skin can be reduced in cost.

  Further, heat is transferred between the heater 13a and the large terminal portion 13b and the head portion 12 through the heat transfer body 13d, and electric wiring for energizing the head portion 12 and electric wiring related to the heater 13a are transmitted. Since the structure is electrically isolated by the heat element 13d, the energization of the head unit 12 for ion introduction and the heating of the head unit 12 by the heater 13a can be appropriately executed without adversely affecting each other. No problem occurs even if the head portion 12 is energized and heated at the same time, and the heating of the skin by the head portion 12 and the introduction of ions into the skin can be performed in synchronism, warming the skin and the cosmetic for ion introduction. By increasing the permeability, ion introduction can be promoted, and ion introduction can be performed on the skin extremely efficiently to exert a cosmetic effect. Furthermore, by arranging the heating unit 13 to be surrounded by the standing wall 11g, the heating unit 13 is not only electrically insulated from the head unit 12 and its energization wiring by the heat transfer body 13d and the standing wall 11g. In addition, heat transfer from the heater 13a to the main body 11 side can be suppressed.

  In the beauty device according to the embodiment, the tilting arm part 14 is attached to the main body part 11 so as to be tiltable and handled integrally. However, the present invention is not limited thereto, and the tilting arm part is separated from the main body part. Also, only when the roller electrode and the irradiation unit are used, it can be attached to the main body so that a desired function can be used.

  Further, in the beauty device according to the embodiment, when ion introduction is performed, the porous covering body 12a soaked with cosmetics such as protective lotion is covered and held on the head portion 12, and the porous covering body is held. The active ingredient contained in the cosmetic in 12a is transferred to the skin side, and the active ingredient is infiltrated into the skin. In addition to this, the head part is directly applied to the skin that has been familiarized with the cosmetic. As an energized state through the body, the active ingredient contained in the skin lotion can be infiltrated into the skin by the current flowing from the head part to the skin. As the skin is warmed by the head heated to the temperature, the activity of the cosmetics on the skin surface increases, and the skin also changes to a state where the active ingredient can easily penetrate, and the ionic active ingredient moves into the skin. Promotes active ingredients deep into the skin It is certainly given the cosmetic effect it through.

  Further, in the beauty device according to the embodiment, when the energized state is set between the head unit 12 and the auxiliary electrode unit 11c and between the pair of roller electrodes 16 and 17, no special adjustment by the user is required. However, in addition to this, a switch may be provided in the operation unit so that the control unit adjusts the strength of the current flowing through the skin based on the user's input operation. A suitable energized state can be obtained for each user corresponding to the sensitivity to the user, and the feeling of use and the beauty effect can be improved. Furthermore, even in the heating mode, the control unit can be configured to adjust the temperature at which the head unit is heated by the heating unit based on the user's input operation, corresponding to the sensitivity to different temperatures depending on the user. Thus, the head portion can be brought to an appropriate temperature, and a comfortable feeling of use can be obtained.

  In the beauty device according to the embodiment, the LED is used as the irradiating unit 15. However, the present invention is not limited to this, and another light source such as a strobe light or an infrared heater may be used. In addition, the irradiation unit 15 is configured such that the LED serving as the light source is disposed between the roller electrodes 16 and 17 and faces the skin 50, but is not limited thereto, and the light source is provided in the tilting arm portion or the main body portion. Alternatively, light may reach the outside from a light source through a light transmission means such as an optical fiber, and light may be irradiated to the skin.

  In the beauty apparatus of the present invention, when the heat application based on the head part heating by the heating part is actually measured, the degree of penetration of the active ingredient into the skin is actually measured, and the application of the heat is a cosmetic effect obtained by the cosmetic operation. An evaluation was made as to whether or not a difference would occur.

  Of the skin (skin), the stratum corneum located in the outermost layer plays a role of a barrier against the movement of substances inside and outside in order to maintain the activity as a human living body. It also means that it becomes the biggest barrier to active ingredient penetration. In this stratum corneum, stratum corneum lipids are known to have a short-period lamellar structure in a normal temperature region such as body temperature and exhibit high barrier properties. It is also known that when this is done, the barrier property is lowered due to the transition to a long-period lamella structure.

  For this reason, in combination with iontophoresis, which is a technique that penetrates the electrolyte component into the skin, especially among water-soluble active ingredients, it can be expected to promote penetration, and to the skin of other active ingredients such as oily ingredients. It can be expected that the penetration of water will be promoted by heating.

  As a measurement, when the skin care sample is applied with various active ingredients, the beauty apparatus of the present invention is applied, and when the heating is performed for 15 minutes and only the ion introduction is performed, the heating and the ion are performed. For each case where introduction is performed, each skin sample is homogenized after 4 hours, and the procedure for extracting and quantifying the active ingredient is performed. In addition, as a comparative example, a skin sample obtained by adding an active ingredient to a skin sample is similarly subjected to extraction and quantification of the skin sample after 4 hours.

  First, the penetration promotion property of the electrolyte component among the water-soluble active ingredients was measured. As this water-soluble active ingredient (electrolyte component), ascorbic acid phosphate sodium salt was used. The measurement was performed for each of the first example in which only heating was performed, the second example in which only ion introduction was performed, the third example in which heating and ion introduction were performed, and the comparative example. FIG. 16 shows a graph indicating a certain amount of detected active ingredient as a ratio with respect to 100% of the comparative example. Therefore, the value on the vertical axis of the graph is (measured effective component detection amount) / (effective component detection amount of comparative example) × 100.

  From FIG. 16, each example has detected amounts of 187%, 362%, and 674% in the order of the first, second, and third, respectively, with respect to the comparative example, and the first that was simply heated. Even in the case of the example, a good effect is obtained with respect to the comparative example, and from the result comparison between the second example and the third example, it can be seen that the permeation promoting effect by ion introduction is remarkably enhanced by heating, It can be seen that the effect of promoting penetration of the electrolyte component into the skin was obtained by heating.

  Next, it measured about the penetration promotion property of a nonelectrolyte component among water-soluble active ingredients. Arbutin was used as the water-soluble active ingredient (non-electrolyte ingredient). The measurement was performed for each case of the fourth example in which only heating was performed, the fifth example in which heating and ion introduction were performed, and the comparative example, and the amount of active ingredient detected as a measurement result was compared in the same manner as described above. FIG. 17 shows a graph in which the ratio is set to 100% of the example.

  FIG. 17 shows that the detected amounts of 429% and 835% were obtained in the fourth and fifth order, respectively, in the examples in comparison with the comparative example, and even in the case of the fourth example in which heating was simply performed, In addition to the good effect on the examples, the results of the fifth example show that the penetration promotion effect is further improved when iontophoresis is also used, and the non-electrolyte component penetration promotion effect on the skin by heating. It turns out that was obtained.

  Furthermore, the penetration promotion property of the oil-soluble active ingredient, in which the effect of ion introduction is difficult to be expected, was also measured. As this oil-soluble active ingredient, vitamin E acetate was used. The measurement was performed for each case of the sixth example and the comparative example in which only heating was performed, and the active ingredient detection amount as the measurement result was expressed as a ratio with respect to this when the comparative example was set to 100% as described above. As shown in FIG.

  From FIG. 18, it can be seen that the heated sixth example obtained a detection amount of 115% as compared with the comparative example, and that the effect of promoting penetration into the skin was also obtained for the oil-soluble active ingredient by heating.

  In this way, from each measurement result, using the beauty device of the present invention, there is a clear difference in the amount of detected active ingredient between when the heating is performed and when it is not, and the change in the stratum corneum resulting from the heating It can be said that due to the change in the active ingredient, the penetration promotion property of the active ingredient is also increased. Thus, it is clear that with the beauty apparatus of the present invention, various active ingredients can be more reliably penetrated into the skin and the beauty effect can be enhanced by performing heating during ion introduction and heating alone. is there.
