Summary of the Invention

Problems to be Solved by the Invention

[0004] In the beauty device disclosed in Patent Document 1, due to its structure, in order to perform an electrical treatment while warming the skin, it is necessary to alternately output an RF (radio wave) high-frequency heating function and other functions, so there is a risk that the beauty effect may decline. Further, with this beauty device, electrical treatment cannot be performed while cooling the skin.

[0005] In the beauty device disclosed in Patent Document 2, since the first electrode is configured in a single plate shape as one electrode portion, it is inferior in extensibility in terms of structure.

[0006] The present disclosure has been made in view of such problems of the prior art. And an object of the present disclosure is to provide a beauty device that can perform other treatments while suppressing a decrease in the beauty effect while warming or cooling the skin. [Means for solving the problem]

[0007] A beauty device according to an aspect of the present disclosure comprises: a first electrode section having a plurality of electrodes that come into contact with the skin; a head frame that supports the plurality of electrodes by a plurality of independent inner edges for each electrode; a heat conduction section made of a deformation-permissible insulating material that is positioned in contact with a portion of each electrode opposite to the side that comes into contact with the skin; and a heating / cooling section positioned on the side of the heat conduction section opposite to the side facing the first electrode section. [Effects of the Invention]

[0008] According to this disclosure, it is possible to provide a beauty device that warms or cools the skin while performing other treatments, thereby minimizing the reduction in the beauty effect. [Brief explanation of the drawing]

[0010] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0011] Figures 1 and 2 are schematic diagrams showing the external appearance of a beauty device 1 according to one embodiment. Figure 1 is a perspective view of the beauty device 1. Figure 2 is a rear view of the beauty device 1 with the side to which the head unit 20 is attached facing forward.

[0012] Beauty device 1 provides beauty effects by applying an electric current to the user's skin through electrical stimulation. As an example, beauty device 1 employs a method in which the user holds beauty device 1 and applies it to their own skin.

[0013] The beauty device 1 first comprises a housing 10 and a head unit 20 having a first electrode section 21.

[0014] The housing 10 constitutes the exterior of the beauty device 1 and is a structurally fundamental component. The housing 10 has a gripping section 11 and a head section 12. The gripping section 11 is a rod-shaped section with a thickness sufficient to be grasped by a human hand. The gripping section 11 houses, for example, a control unit 41 and a power supply unit 42 inside, and also includes a second electrode section 13, part of which is exposed to the outside. The head section 12 is continuous with one end of the gripping section 11 and is the part in which the head unit 20 and the third electrode section 14 are installed back to back.

[0015] Figures 3, 4, and 5 are schematic diagrams of the head unit 20. Figure 3 is a perspective view of the head unit 20. Figure 4 is an exploded view of the head unit 20. Figure 5 is a cross-sectional view of the head unit 20.

[0016] The head unit 20 operates when power is supplied and performs a predetermined treatment on the user's skin. The head unit 20 includes a first electrode portion 21, a heat conduction portion 22, a heating / cooling portion 23, and a conductive portion 24.

[0017] The first electrode portion 21 is arranged on the outermost contour facing the outside of the housing 10 and is an electrode group that contacts the user's skin during treatment. The first electrode portion 21 is composed of a plurality of electrodes. In this embodiment, as an example, it is assumed to be composed of three electrodes, namely, a first electrode 21a, a second electrode 21b, and a third electrode 21c.

[0018] The first electrode 21a, the second electrode 21b, and the third electrode 21c are each formed by machining a plate material made of a metal such as a titanium alloy into a convex shape. The planar shape of the surface that contacts the skin in each of the first electrode 21a, the second electrode 21b, and the third electrode 21c is approximately a long rectangle. And the first electrode 21a, the second electrode 21b, and the third electrode 21c are arranged in parallel in a direction orthogonal to the longitudinal direction and are non-contact with each other. In the example of this embodiment, the first electrode 21a is arranged at a position farthest from the gripping portion 11 of the housing 10. The third electrode 21c is arranged at a position closest to the gripping portion 11 of the housing 10. The second electrode 21b is arranged at a position sandwiched between the first electrode 21a and the third electrode 21c. In this case, the planar shape of each of the first electrode 21a and the third electrode 21c may be a long rectangle including a curved portion that protrudes on the side opposite to the side adjacent to the second electrode 21b.

[0019] The heat conduction part 22 transmits the heat energy generated from the heating / cooling part 23 to the first electrode part 21, or absorbs the heat energy possessed by the first electrode part 21 by the heating / cooling part 23. The heat conduction part 22 is made of an insulating material that allows deformation, and for example, it may be any one of a heat conduction sheet, a heat conduction paste, or a heat conduction grease. The heat conduction part 22 is arranged such that a part of it contacts the first electrode part 21 on the back side of the first electrode part 21, that is, on the side opposite to the side where the first electrode part 21 contacts the skin. The heat conduction part 22 has a first conduction part 22a, a second conduction part 22b, and a third conduction part 22c. The first conduction part 22a is a part arranged on the back side of the first electrode 21a. The second conduction part 22b is a part arranged on the back side of the second electrode 21b. The third conduction part 22c is a part arranged on the back side of the third electrode 21c. Here, the first conduction part 22a, the second conduction part 22b, and the third conduction part 22c may be separated from each other, or may be a continuous integral body with each other.

[0020] The heating / cooling part 23 is a device that heats or cools the first electrode part 21. In this embodiment, as an example, it is a Peltier element (thermoelectric conversion element). The heating / cooling part 23 is arranged on the back side of the heat conduction part 22, that is, on the side opposite to the side where the heat conduction part 22 faces the first electrode part 21.

[0021] The conductive part 24 electrically connects the first electrode part 21 and the control unit 41. The conductive part 24 includes a plurality of conductors, which are composed of, for example, a wire harness, a metal coil spring, or a metal leaf spring. In this embodiment, the conductive part 24 includes a first conductor 24a, a second conductor 24b, and a third conductor 24c. When each conductor is a wire harness, it is connected to the first electrode part 21 by soldering or the like. On the other hand, when each conductor is a coil spring or a leaf spring, it is connected to the first electrode part 21 by physical contact. For example, the first conductor 24a is a coil spring that electrically connects the first electrode 21a and the control unit 41. The second conductor 24b is a coil spring that electrically connects the second electrode 21b and the control unit 41. The third conductor 24c is a coil spring that electrically connects the third electrode 21c and the control unit 41. Note that the wiring that electrically connects each conductor to the control unit 41 is not shown.

[0022] The head unit 20 also includes a heat diffusion unit 25, a heat sink 26, a fan 27, a first temperature detection unit 28, and a second temperature detection unit 29.

[0023] The heat diffusion section 25 is positioned between the heat conduction section 22 and the heating / cooling section 23. The heat diffusion section 25 may be made from a metal plate made of, for example, an aluminum alloy, or from a processed graphite sheet. In this embodiment, the heat diffusion section 25 has a flat plate section 25a having a plane perpendicular to the direction in which the heat conduction section 22 and the heating / cooling section 23 face each other. The flat plate section 25a may have a through hole 25b in which the detection terminal of the first temperature detection section 28 can be positioned. The flat plate section 25a may also have two protruding pieces 25c at its edge that engage with the fixing section 31d of the base frame 31.

[0024] With the heat diffusion section 25, even if the surface area of ​​the heating / cooling section 23 is smaller than the total surface area of ​​the first electrode section 21 when viewed in a direction in which the first electrode section 21 and the heating / cooling section 23 face each other, heat can be spread throughout the entire first electrode section 21, enabling heating or cooling with less temperature unevenness. Furthermore, the heating / cooling section 23 and the heat diffusion section 25 may be connected via thermal conductive grease to reduce thermal resistance and improve heat transfer efficiency. In other words, with the above configuration, the first electrode section 21 is thermally connected to the heating / cooling section 23 via the heat conductive section 22 and the heat diffusion section 25. However, the heat diffusion section 25 is not an essential component of the head unit 20 and may be omitted.

[0025] The heat sink 26 is a metal block that is thermally connected to the heating / cooling section 23 from the side opposite to the side facing the heat conduction section 22 and the heat diffusion section 25. The heat sink 26 may have a groove 26a on the side facing the heating / cooling section 23, on which the detection terminal of the second temperature detection section 29 can be placed. The heat sink 26 may have a fin section 26b on the side opposite to the side facing the heating / cooling section 23. In addition, the heating / cooling section 23 and the heat sink 26 may be connected via thermal conductive grease to reduce thermal resistance and increase heat transfer efficiency.

[0026] The fan 27 is positioned, for example, so that its airflow surface faces the fin portion 26b provided on the heat sink 26, thereby promoting heat dissipation by the heat sink 26. However, if the heat dissipation performance of the heating / cooling unit 23 itself is sufficient, the installation of at least one of the heat sink 26 or the fan 27 may be omitted.

[0027] The first temperature detection unit 28 detects the temperature on the first electrode unit 21 side of the heating / cooling unit 23. On the other hand, the second temperature detection unit 29 detects the temperature on the heat sink 26 side of the heating / cooling unit 23. The first temperature detection unit 28 and the second temperature detection unit 29 are, for example, thermistors. The first temperature detection unit 28 and the second temperature detection unit 29 are each electrically connected to the control unit 41. The first temperature detection unit 28 and the second temperature detection unit 29 are used in heating control or cooling control by the control unit 41 as described later, but they may also be used to detect abnormal temperatures in advance due to a fan 27 failure or a power supply circuit failure.

[0028] Furthermore, the head unit 20 includes a head frame 30 and a base frame 31.

[0029] Figure 6 is a schematic plan view of the head frame 30 as seen along the direction in which the first electrode section 21 is installed.

[0030] The head frame 30 becomes part of the exterior of the housing 10 when the head unit 20 is attached to the head portion 12, and supports the first electrode portion 21. The head frame 30 has a substantially rectangular annular frame 30a and a plurality of beam-like portions. The annular frame 30a is the part that defines the outer shape of the head frame 30. The plurality of beam-like portions are parts that divide the spatial area inside the annular frame 30a according to the arrangement of the electrodes that constitute the first electrode portion 21. In this embodiment, the first electrode portion 21 is composed of three electrodes: a first electrode 21a, a second electrode 21b, and a third electrode 21c. Therefore, the head frame 30 has the following two beam-like portions that divide the spatial area inside the annular frame 30a into three spatial areas corresponding to the arrangement of the three electrodes. The first beam-like portion 30b is a beam-like portion that separates the first spatial area S1 in which the first electrode 21a is placed from the second spatial area S2 in which the second electrode 21b is placed. The second beam-like portion 30c is a beam-like portion that separates the second spatial region S2 from the third spatial region S3 in which the third electrode 21c is located.

[0031] The first beam-like portion 30b defines the first inner peripheral edge 30d surrounding the first spatial region S1. The shape of the first inner peripheral edge 30d matches the outer peripheral shape of the first electrode 21a. The first electrode 21a is then fixed to the first inner peripheral edge 30d by insert molding.

[0032] The first beam-like portion 30b and the second beam-like portion 30c define the second inner peripheral edge 30e that surrounds the second spatial region S2. The shape of the second inner peripheral edge 30e matches the outer peripheral shape of the second electrode 21b. The second electrode 21b is then fixed to the second inner peripheral edge 30e by insert molding.

[0033] The second beam-like portion 30c defines the third inner peripheral edge 30f surrounding the third spatial region S3. The shape of the third inner peripheral edge 30f matches the outer peripheral shape of the third electrode 21c. The third electrode 21c is then fixed to the third inner peripheral edge 30f by insert molding.

[0034] The annular frame 30a may have an engaging portion 30g that engages with a part of the head portion 12 when the head unit 20 is attached to the head portion 12.

[0035] Furthermore, the head frame 30 has partition portions 32 that further divide the first spatial region S1, the second spatial region S2, and the third spatial region S3, either integrally with the annular frame 30a, etc., or as separate members from the annular frame 30a, etc. In this embodiment, the partition portion 32 is configured as a single rod perpendicular to the first beam-like portion 30b and the second beam-like portion 30c. The partition portion 32 includes a first wall portion 32a, a second wall portion 32b, and a third wall portion 32c that are continuous in series with respect to each other.

[0036] The first wall portion 32a divides the first spatial region S1 into two. In one region formed by the division, the first conductive portion 22a of the heat conductive portion 22 is arranged. On the other hand, the other region formed by the division becomes the first conductive region S1a in which the first conductor 24a of the conductive portion 24 is routed.

[0037] The second wall portion 32b divides the second spatial region S2 into two. In one region formed by the division, the second conductive portion 22b of the heat conductive portion 22 is arranged. On the other hand, the other region formed by the division becomes the second conductive region S2a in which the second conductor 24b of the conductive portion 24 is arranged.

[0038] The third wall portion 32c divides the third spatial region S3 into two. In one region formed by the division, the third conductive portion 22c of the heat conductive portion 22 is arranged. On the other hand, the other region formed by the division becomes the third conductive region S3a in which the third conductor 24c of the conductive portion 24 is arranged.

[0039] Here, the first conducting region S1a, the second conducting region S2a, and the third conducting region S3a each only need to have enough space for a coil spring, which is an example of each conductor, to pass through. In other words, the first conducting region S1a, the second conducting region S2a, and the third conducting region S3a may be smaller than the region in which the individual conducting parts of the heat conducting section 22 are arranged.

[0040] The base frame 31 supports some of the components of the head unit 20. In this embodiment, the base frame 31 has a cylindrical body 31a with a rectangular opening. The cylindrical body 31a has an inner wall portion 31b that supports the heating / cooling section 23. The cylindrical body 31a also has three conductor support portions 31c that each support one of the three conductors constituting the conductive section 24. In this embodiment, since each conductor is a coil spring, each of the three conductor support portions 31c has a cylindrical shape that can support one coil spring. Here, the first conductive region S1a, the second conductive region S2a, and the third conductive region S3a provided in the head frame 30 can each penetrate a part of one of the conductor support portions 31c. The cylindrical body 31a also has two fixing portions 31d that engage with the protruding pieces 25c provided in the heat diffusion section 25. One of the fixing portions 31d is provided with a first penetration portion 31e that can support the first temperature detection section 28. The other fixed portion 31d is provided with a second through-port 31f capable of supporting the second temperature detection unit 29.

[0041] Furthermore, the beauty device 1 may also include a second electrode section 13. The second electrode section 13 is positioned on the gripping section 11 of the housing 10 and is an electrode that touches the skin surface in a different area from the first electrode section 21. The second electrode section 13 has an oval shape in plan view that curves along the outer surface of the gripping section 11 and is positioned on the outer surface of the gripping section 11 opposite to the first electrode section 21, that is, on the side where the third electrode section 14 is exposed. As a result, when a user who is gripping the gripping section 11 positions the first electrode section 21 near the skin of their face, the second electrode section 13 comes into contact with the user's palm. At this time, the second electrode section 13 and the palm are in close contact with each other strongly and over a wide area, so that a predetermined voltage can be reliably applied between the first electrode section 21 and the second electrode section 13 via the user's body, and a potential gradient can be generated near the surface of the skin. However, if the treatment mode of the beauty device 1 is limited, the installation of the second electrode section 13 may be omitted.

[0042] Furthermore, the beauty device 1 may also include a third electrode section 14. The third electrode section 14 comes into contact with the skin of an individual, such as a human body, and can generate an electroporation effect by continuously generating, for example, a pulsed electric field on the skin, thereby forming tiny pores in the stratum corneum. However, if the treatment modes of the beauty device 1 are limited, the installation of the third electrode section 14 may be omitted.

[0043] Furthermore, the beauty device 1 includes a control unit 41 and a power supply unit 42.

[0044] The control unit 41, although not shown, is electrically connected to the first electrode section 21, the second electrode section 13, and the third electrode section 14. The control unit 41 includes components that constitute a circuit for applying voltage between two electrodes selected from the first electrode 21a, the second electrode 21b, and the third electrode 21c that make up the first electrode section 21, or between the first electrode section 21 and the second electrode section 13. The control unit 41 also includes components that constitute a circuit for applying voltage to the third electrode section 14 to generate an electric field, such as a pulsed field. Furthermore, the control unit 41 includes a processor and the like for driving these circuits. The power supply unit 42 is electrically connected to the control unit 41 and supplies power to the circuits within the control unit 41.

[0045] Furthermore, the beauty device 1 is equipped with switch buttons 15 as an operating section. The switch buttons 15 are exposed to the outside, for example, from the gripping section 11 of the housing 10, and are operated by the user. There may be multiple switch buttons 15, such as a power / mode switch operated when turning the power on / off and switching treatment modes, or a level switch operated when adjusting the power supply level.

[0046] Next, I will explain the function of beauty device 1.

[0047] The user turns on the power by operating the switch button 15, and then selects the treatment mode to be used when performing a treatment with the beauty device 1.

[0048] According to the beauty device 1, first, the first electrode unit 21 can be heated in conjunction with the treatment applied to the skin using the first electrode unit 21. When the user selects a treatment mode that heats the first electrode unit 21, the control unit 41 drives the heating / cooling unit 23 to heat the side of the first electrode unit 21. Hereinafter, the "side of the first electrode unit 21" in the heating / cooling unit 23 will be simply referred to as the "electrode side". The thermal energy generated on the electrode side of the heating / cooling unit 23 is transmitted in the order of the heat diffusion unit 25, the heat conduction unit 22, and the first electrode unit 21, and finally the first electrode unit 21 is heated. In this embodiment, when the heating / cooling unit 23 is a Peltier element, the side of the heat sink 26 becomes colder than the ambient temperature due to the heat absorption of the heating / cooling unit 23, so heat dissipation by the fan 27 is unnecessary. Hereinafter, the "side of the heat sink 26" in the heating / cooling unit 23 will be simply referred to as the "heat sink side".

[0049] By warming the first electrode section 21 in this way, the skin is warmed in conjunction with the treatment using the first electrode section 21. This is expected to promote blood circulation and enhance the beauty effect, or to provide a more comfortable treatment experience due to the warmth of the skin.

[0050] On the other hand, in order to obtain a better warming effect, it is necessary to rapidly raise the temperature of the first electrode section 21 within the usage time of the beauty device 1, which is usually considered to be only a few minutes. However, although a higher thermal energy for heating can increase the rate at which the temperature of the first electrode section 21 rises, there is a risk that the temperature may become too high if heating continues. Therefore, when heating the first electrode section 21, the control unit 41 may perform the control shown in Figure 7.

[0051] Figure 7 is a flowchart showing the control that the control unit 41 can perform when heating the first electrode section 21.

[0052] First, the control unit 41 heats the first electrode unit 21 by initiating heating / cooling on the electrode side of the heating / cooling unit 23 (step S101). Next, the control unit 41 measures the temperature of the first electrode unit 21 by having the first temperature detection unit 28 detect the temperature on the electrode side of the heating / cooling unit 23 (step S102). Next, the control unit 41 determines whether the temperature obtained in step S102 exceeds a pre-set threshold (step S103). The threshold set here may be, for example, a temperature that does not cause burns to the skin and is comfortable for the user to use.

[0053] If the control unit 41 determines in step S103 that the temperature has not exceeded the threshold (NO), it determines whether to continue heating the first electrode unit 21 (step S104). If the control unit 41 determines in step S104 to continue heating (YES), it returns to step S102. On the other hand, if the control unit 41 determines in step S104 not to continue heating (NO), it stops heating the first electrode unit 21 (step S106) and terminates the heating control.

[0054] On the other hand, if the control unit 41 determines in step S103 that the temperature has exceeded a threshold (YES), it temporarily stops heating the first electrode unit 21 (step S105). At this time, the control unit 41 may stop heating for a predetermined time, or it may stop heating until the temperature on the electrode side of the heating / cooling unit 23 drops to a predetermined temperature. After that, the control unit 41 returns to step S101. This prevents excessive heating by the first electrode unit 21.

[0055] Furthermore, according to the beauty device 1, it is also possible to cool the first electrode unit 21 in conjunction with the treatment applied to the skin using the first electrode unit 21. When the user selects a treatment mode to cool the first electrode unit 21, the control unit 41 drives the heating / cooling unit 23 to cool the electrode side of the first electrode unit 21. Finally, the first electrode unit 21 is cooled. In this embodiment, when the heating / cooling unit 23 is a Peltier element, the heat sink side of the heating / cooling unit 23 becomes hotter than the ambient temperature due to heat generation, causing the heat sink 26 to heat up. The heat sink 26 dissipates heat from the fins 26b. The control unit 41 also drives the fan 27 as needed to blow air toward the heat sink 26, promoting heat dissipation by the heat sink 26. At this time, the control unit 41 may have the second temperature detection unit 29 detect the temperature of the heat sink side of the heating / cooling unit 23 and determine whether or not to drive the fan 27 based on that temperature.

[0056] By cooling the first electrode unit 21 in this way, the skin is cooled in conjunction with the treatment using the first electrode unit 21. This allows for cooling the skin after treatment, or for cooling the skin surface to prevent burns while enhancing the beauty effects of RF (radio frequency).

[0057] On the other hand, when cooling the first electrode section 21, the control unit 41 may perform the control shown in Figure 8 to rapidly lower the temperature of the first electrode section 21 while preventing it from becoming too cold.

[0058] Figure 8 is a flowchart showing the control that the control unit 41 can perform when cooling the first electrode section 21.

[0059] First, the control unit 41 cools the first electrode unit 21 by initiating the heating / cooling unit 23 to begin cooling the electrode side (step S201). Next, the control unit 41 measures the temperature of the first electrode unit 21 by having the first temperature detection unit 28 detect the temperature on the electrode side of the heating / cooling unit 23 (step S202). Next, the control unit 41 determines whether the temperature obtained in step S202 has fallen below a pre-set threshold (step S203). For example, since the temperature at which excessive cooling can cause frostbite is far from the temperature at which the user can comfortably use the device, the threshold set here may be determined based on the temperature at which the user can comfortably use the device.

[0060] If the control unit 41 determines in step S203 that the temperature has not fallen below the threshold (NO), it determines whether to continue cooling the first electrode unit 21 (step S204). If the control unit 41 determines in step S204 to continue cooling (YES), it returns to step S202. On the other hand, if the control unit 41 determines in step S204 not to continue cooling (NO), it stops cooling the first electrode unit 21 (step S206) and terminates the cooling control.

[0061] On the other hand, if the control unit 41 determines in step S203 that the temperature is below a threshold (YES), it temporarily stops cooling the first electrode unit 21 (step S205). At this time, the control unit 41 may stop cooling for a predetermined time, or it may stop cooling until the temperature on the electrode side of the heating / cooling unit 23 rises to a predetermined temperature. After that, the control unit 41 returns to step S201. This prevents excessive cooling by the first electrode unit 21.

[0062] In this embodiment, a second temperature detection unit 29 for detecting the temperature on the heat sink side of the heating / cooling unit 23 is installed in the head unit 20. Therefore, the control in each step S202 and step S203 in the control shown in Figure 8 may be modified as follows. That is, the control unit 41 may cause the second temperature detection unit 29 to detect the temperature on the heat sink side of the heating / cooling unit 23, and determine whether to temporarily suspend the cooling of the first electrode unit 21 based on whether the temperature obtained at this time exceeds a pre-set threshold.

[0063] Furthermore, the beauty device 1 is capable of performing treatments that provide beauty effects through electrical stimulation, either simultaneously with or independently of heating or cooling the first electrode section 21. Specifically, the control unit 41 controls the electrical path and waveform flowing through the first electrode section 21 and the second electrode section 13, respectively, according to the treatment mode selected by the user, thereby executing electrical treatments that provide various beauty effects.

[0064] First, as an electrical treatment related to iontophoresis, electricity in the kHz band may be passed between at least two electrodes of the first electrode section 21, or between at least one electrode of the first electrode section 21 and the second electrode section 13. Iontophoresis is expected to promote the transdermal penetration of beauty ingredients such as lotions or serums, thereby enhancing the beauty effects of cosmetics.

[0065] Furthermore, as an electrical treatment related to ion export (cleansing), electricity in the kHz band may be passed between at least two electrodes of the first electrode section 21, or between at least one electrode of the first electrode section 21 and the second electrode section 13. With ion export, when the treatment is performed through cotton, it is expected to have the effect of adsorbing and removing fine dirt from the skin.

[0066] Furthermore, as an electrical treatment related to microcurrents, electricity in the kHz band may be passed between at least two electrodes of the first electrode section 21, or between at least one electrode of the first electrode section 21 and the second electrode section 13. The action of microcurrents is expected to promote skin cell activity, keep the skin healthy, refine skin texture, and reduce wrinkles.

[0067] Furthermore, as an electrical treatment related to EMS (Electrical Muscle Stimulation), a low frequency in the Hz range may be applied between at least two electrodes of the first electrode section 21. EMS is expected to have effects such as contracting facial muscles to lift the face and promoting blood circulation.

[0068] Furthermore, as an electrical treatment related to RF, MHz band electricity may be passed between at least two electrodes of the first electrode section 21. The action of RF is expected to have effects such as warming the skin from within, making the skin firmer, reducing wrinkles, and promoting blood circulation.

[0069] The beauty effects and current application conditions for each electrical treatment described above are examples only and are not limited to these. Furthermore, treatments that provide various beauty effects may be combined and performed in a time-division manner. For example, within one cycle, electrical treatments such as iontophoresis with an output time ratio of 80% followed by EMS with an output time ratio of 20% may be repeated alternately.

[0070] Furthermore, by combining the five electrical treatments exemplified above with the effect of warming the first electrode section 21, the skin is warmed and blood circulation is promoted, thereby further enhancing the beauty effects of each electrical treatment. In addition, for treatments that are less likely to cause discomfort, such as ion introduction, ion export, or microcurrent, the warming effect provides a comfortable treatment experience.

[0071] On the other hand, by combining the five electrical treatments exemplified above with the effect of cooling the first electrode section 21, the skin can be cooled down when performed after thermal or each electrical treatment. Furthermore, when heating the skin from the surface to the deep layers with RF, the surface temperature is higher than the deep layer temperature, so if the deep layers are heated sufficiently, the surface will be overheated. Therefore, by performing RF treatment while cooling the surface, the deep layers can be heated while minimizing the risk of burns, thereby improving firmness from deep within the skin.

[0072] Next, I will explain the effects of beauty device 1.

[0073] First, the beauty device 1 comprises a first electrode section 21 having a plurality of electrodes that come into contact with the skin, and a head frame 30 that supports the plurality of electrodes with a plurality of independent inner edges for each electrode. The beauty device 1 also comprises a heat conduction section 22 made of an insulating material that allows deformation, which is positioned in contact with a portion of each electrode opposite to the side that comes into contact with the skin. Furthermore, the beauty device 1 comprises a heating / cooling section 23 positioned on the side of the heat conduction section 22 opposite to the side facing the first electrode section 21.

[0074] Here, the multiple electrodes of the first electrode section 21 correspond to the first electrode 21a, the second electrode 21b, and the third electrode 21c in the above example. Furthermore, the multiple inner edges of the head frame 30 that support these electrodes correspond to the first inner edge 30d, the second inner edge 30e, and the third inner edge 30f in the above example.

[0075] According to this beauty device 1, firstly, since the first electrode section 21 has multiple electrodes, various electrical treatments as exemplified above can be performed by appropriately changing the usage conditions of each electrode. Furthermore, according to the beauty device 1, since it has a heating / cooling section 23, each electrode constituting the first electrode section 21 can be heated or cooled via the heat conduction section 22.

[0076] Here, the heat conduction portion 22 is made of a material that allows deformation. Therefore, especially when the first electrode portion 21 consists of multiple electrodes, the heat conduction portion 22 can be easily positioned on the side of each electrode opposite to the side that contacts the skin, i.e., on the back side of each electrode, in accordance with the shape of the back side, while improving adhesion.

[0077] Furthermore, since the heat conduction section 22 is made of an insulating material, even if the heat conduction section 22 is an integral part that comes into contact with each electrode, especially when the first electrode section 21 consists of multiple electrodes, current flow between the electrodes can be avoided. Therefore, the heat conduction section 22 allows for control of each electrode, and the heating / cooling section 23 can be placed near the first electrode section 21, further improving heat conduction efficiency. In other words, the beauty device 1 can perform other beauty treatments to the same extent as when the beauty treatment is performed alone, while providing a highly comfortable warming care by warming the first electrode section 21. Also, the beauty device 1 can perform other beauty treatments to the same extent as when the beauty treatment is performed alone, while providing a highly comfortable cooling care by cooling the first electrode section 21.

[0078] As described above, according to this embodiment, it is possible to provide a beauty device 1 that performs other treatments while warming or cooling the skin, while suppressing a decrease in the beauty effect.

[0079] Furthermore, the beauty device 1 may include multiple conductors that supply current to each electrode. The head frame 30 may have partition portions 32 that divide each of the multiple spatial regions defined for each inner periphery into two regions. At least a portion of the heat conduction portion 22 may be located in one region, and at least a portion of the conductor may be located in the other region.

[0080] Here, the multiple conductors correspond to the first conductor 24a, the second conductor 24b, and the third conductor 24c in the above example. The multiple spatial regions defined for each inner periphery correspond to the first spatial region S1, the second spatial region S2, and the third spatial region S3 in the above example. Furthermore, among the regions partitioned by the partition portion 32, the regions where at least a part of the conductors are arranged correspond to the first conductive region S1a, the second conductive region S2a, and the third conductive region S3a.

[0081] For example, let's focus on the first spatial region S1 where the first electrode 21a of the first electrode portion 21 is located. The first spatial region S1 is separated by a partition portion 32 into a region where the first conductive portion 22a, which is part of the heat conductive portion 22, is located, and a first conductive region S1a where the first conductor 24a, which conducts current to the first electrode 21a, is routed. Therefore, for example, if the first conductive portion 22a is formed from a fluid material, even if the fluid first conductive portion 22a is injected into a predetermined region within the first spatial region S1 during manufacturing, its inflow into the first conductive region S1a is prevented. Thus, in the head frame 30, the first conductive region S1a can be reliably secured, and the heat conductive portion 22 can be easily positioned while increasing its adhesion to the first electrode 21a.

[0082] Furthermore, in beauty device 1, the heating / cooling section 23 may be a Peltier element.

[0083] According to this beauty device 1, the heating and cooling effect on the entire first electrode section 21 can be obtained using a Peltier element with a small surface area, as switching between heating and cooling is easy. This can contribute to reducing the cost or miniaturizing the beauty device 1.

[0084] Furthermore, the beauty device 1 may include at least one of the following: a first temperature detection unit 28 that detects the temperature on the side of the heating / cooling unit 23 facing the first electrode unit 21, or a second temperature detection unit 29 that detects the temperature on the side of the heating / cooling unit 23 opposite to the side facing the first electrode unit 21. The beauty device 1 may also include a control unit 41 that controls the heating or cooling operation by the heating / cooling unit 23 by comparing the temperature detected by the first temperature detection unit 28 or the second temperature detection unit 29 with a threshold value.

[0085] With this beauty device 1, even when attempting to rapidly increase the temperature of the first electrode section 21, it is possible to perform a comfortable treatment on the user while avoiding excessive temperature increases. Similarly, even when attempting to rapidly decrease the temperature of the first electrode section 21, it is possible to perform a comfortable treatment on the user.

[0086] Furthermore, the beauty device 1 may also include a second electrode portion 13 that contacts a different part of the skin than the first electrode portion 21.

[0087] This beauty device 1 allows for ion introduction or ion extraction treatments, using the first electrode section 21, the second electrode section 13, and the user's body as a closed circuit, to be performed while warming or cooling the skin.

[0088] (Note) Based on the above description of embodiments, the following technologies are disclosed.

[0090] According to this beauty device 1, firstly, since the first electrode section 21 has multiple electrodes, various electrical treatments as exemplified above can be performed by appropriately changing the usage conditions of each electrode. Furthermore, according to the beauty device 1, since it has a heating / cooling section 23, each electrode constituting the first electrode section 21 can be heated or cooled via the heat conduction section 22.

[0091] Here, the heat conduction portion 22 is made of a material that allows deformation. Therefore, especially when the first electrode portion 21 consists of multiple electrodes, the heat conduction portion 22 can be easily positioned on the side of each electrode opposite to the side that contacts the skin, i.e., on the back side of each electrode, in accordance with the shape of the back side, while improving adhesion.

[0092] Furthermore, since the heat conduction section 22 is made of an insulating material, even if the heat conduction section 22 is an integral part that comes into contact with each electrode, especially when the first electrode section 21 consists of multiple electrodes, current flow between the electrodes can be avoided. Therefore, the heat conduction section 22 allows for control of each electrode, and the heating / cooling section 23 can be placed near the first electrode section 21, further improving heat conduction efficiency. In other words, the beauty device 1 can perform other beauty treatments to the same extent as when the beauty treatment is performed alone, while providing a highly comfortable warming care by warming the first electrode section 21. Also, the beauty device 1 can perform other beauty treatments to the same extent as when the beauty treatment is performed alone, while providing a highly comfortable cooling care by cooling the first electrode section 21.

[0094] (Technology 2) The beauty device according to Technology 1, comprising a plurality of conductors that conduct electricity to each of the electrodes, wherein the head frame has a partition portion that divides each of the plurality of spatial regions defined for each inner periphery into two regions, at least a portion of the heat conducting portion is arranged in one of the regions, and at least a portion of the conductor is arranged in the other region.

[0095] For example, let's focus on the first spatial region S1 where the first electrode 21a of the first electrode portion 21 is located. The first spatial region S1 is separated by a partition portion 32 into a region where the first conductive portion 22a, which is part of the heat conductive portion 22, is located, and a first conductive region S1a where the first conductor 24a, which conducts current to the first electrode 21a, is routed. Therefore, for example, if the first conductive portion 22a is formed from a fluid material, even if the fluid first conductive portion 22a is injected into a predetermined region within the first spatial region S1 during manufacturing, its inflow into the first conductive region S1a is prevented. Thus, in the head frame 30, the first conductive region S1a can be reliably secured, and the heat conductive portion 22 can be easily positioned while increasing its adhesion to the first electrode 21a.
