Description

TECHNICAL FIELD

[0001] The present disclosure relates to a cosmetic device. BACKGROUND

[0002] In the past, as a cosmetic device, as shown in the following Patent Literature 1, a device in which a brush-like body having a plurality of pins is provided to a main body is known.

[0003] In the Patent Literature 1, by embedding an electrically conductive elastic body in the entire axial direction of the pin body, the pin body has a soft flexibility.

[0004] In addition, as shown in the following Patent Literature 2, a cosmetic device in which a plurality of tip electrodes are provided to a movable housing that performs a planar reciprocating movement within a hand-held housing, and each tip electrode is urged in a protruding direction by a spring is also known.

[0006] PATENT LITERATURE

[0007] Patent Literature 1: Japanese Patent No. 7074935

[0008] Patent Literature 2: Japanese Patent Application Laid-Open No. 2000-140131 SUMMARY

[0009] However, the cosmetic device disclosed in the Patent Literature 1 is configured so that the pin body cannot move in the axial direction. Therefore, in the case of a curved portion of the skin, it can be difficult for the pin body to stably contact the skin, and thus the skin can not be effectively cosmetically treated.

[0010] In addition, in the cosmetic device disclosed in the Patent Literature 2, since the tip electrodes can be slid in the protruding direction, the tip electrodes can stably contact the skin. However, if the tip electrodes are slid in the protruding direction, a gap is generated between the tip electrodes and the housing, and thus the waterproof property of the cosmetic device can be degraded, and the reliability of the electrical connection of the tip electrodes can be impaired.

[0011] Thus, in the above-described conventional technology, the portion where the cosmetic treatment can be effectively performed is limited, or the environmental conditions, the method of use, and the like when using the cosmetic device are limited, and thus the use convenience of the cosmetic device is not good.

[0012] Therefore, an object of the present disclosure is to obtain a cosmetic device that can more effectively perform cosmetic treatment of the skin while optimizing the use convenience.

[0013] A cosmetic device of a technical solution of the present disclosure includes an electrode portion having a plurality of electrode pins, a main body portion that holds the electrode portion in a state in which the plurality of electrode pins protrude outward, and an elastic structure that is disposed inside the main body portion in a state of holding the plurality of electrode pins.

[0014] According to the present disclosure, a cosmetic device that can more effectively perform a cosmetic treatment of skin while optimizing use convenience can be obtained. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0029] Hereinafter, the embodiments will be explained in detail with reference to the drawings. However, detailed explanation is sometimes omitted. For example, detailed explanation of matters already known or repeated explanation of substantially identical structures is sometimes omitted.

[0030] Further, the drawings and the following explanation are provided so that those skilled in the art can fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims by these.

[0031] In addition, in the following embodiments and modifications thereof, the upward and downward directions in the state in which the cosmetic device is arranged with the head portion located above the holding portion are defined as the upward and downward directions of the cosmetic device, and explanation is made. In addition, in the state in which the cosmetic device is held by a user or the like in order to use it in the usual manner, the side opposite to the person holding it is defined as the front in the front and rear directions, and explanation is made.

[0032] (Embodiment)

[0033] As shown in Figures 1-8 , the cosmetic device 10 of the present embodiment includes a main body portion 20 and an electrode portion 30 held to the main body portion 20. The electrode portion 30 is provided with an electrode group 30a composed of a plurality of electrode pins (electrodes of a plurality of pin bodies) 311. The electrode portion 30 is provided to the main body portion 20 in a state in which the electrode group 30a protrudes outward (frontward) from the main body portion 20.

[0034] Further, in a state in which the top ends (top end 311a of each electrode pin 311) of the electrode group 30a contact the skin of a user or the like, each electrode pin 311 applies an electric stimulus to the skin, whereby the skin of the user or the like is cosmetically treated (cosmetic treatment in which a cosmetic effect is exerted on the skin).

[0035] As such cosmetic treatment, for example, cosmetic treatment of the skin by EMS, specifically, cosmetic treatment in which a muscle is caused to perform a contraction movement (EMS: Electrical Muscle Stimulation) by passing a pulsed electric current to the skin of a user or the like, and the like can be cited. Further, if the cosmetic treatment of the skin is performed by EMS, care such as promotion of the flow of lymph fluid for recovery from fatigue or the like or enhancement of the muscle can be performed.

[0036] Thus, the beauty device 10 of this embodiment is a device that beautifies the skin of a user etc. by applying electrical stimulation from the plurality of electrode pins 311. In other words, the beauty device 10 of this embodiment is a brush-type beauty device having electrodes with a plurality of pin bodies.

[0037] In this embodiment, the main body 20 is elongated in one direction (vertical), making it sized so that the user can hold it with one hand. Furthermore, when using the beauty device 10, the user can grasp the main body 20. Thus, the main body 20 is formed with a grip portion 20a that the user can grasp manually. In this embodiment, one side (the lower side) of the main body 20 serves as the grip portion 20a, while the other side (the upper side) serves as the head portion 20b that holds the electrode unit 30.

[0038] The main body 20 includes a main body case 21 that forms the outer shell of the main body 20. The main body case 21 can be formed using, for example, a synthetic resin material having insulating properties.

[0039] In the present embodiment, the main body case 21 is formed by joining a plurality of divided bodies, and a cavity is formed inside the main body case 21 formed by joining the divided bodies. Various electrical components are housed in the cavity.

[0040] Specifically, if Figure 9 As shown, the main body housing 21 includes a front housing 211, a rear housing 212, and a head cover 213. The front housing 211, the rear housing 212, and the head cover 213 are joined together to form the main body housing 21 having a cavity therein.

[0041] In addition, the main body shell 21 accommodates the portion of the electrode part 30 other than the electrode group 30a, the battery 251 that supplies power to the electrode part 30, the battery base 25 that holds the battery 251, and the circuit board (control part) 24 that controls the on / off of the power supply.

[0042] In this embodiment, the circuit board (control unit) 24 is placed on the front side of the battery base 25. The battery base 25 holding the battery 251 and having the circuit board (control unit) 24 placed thereon is housed in the first housing space 2121 formed in the lower portion of the rear housing 212.

[0043] Further, the battery 251, the battery base 25, and the circuit board (control section) 24 are covered from the front side by the inner cover 22 in a state of being accommodated in the first accommodation space 2121. At this time, the inner cover 22 covers the battery 251, the battery base 25, and the circuit board (control section) 24 in a state of being sealed from a gap by the seal member 23. By so doing, waterproofness of a space in which the battery 251, the battery base 25, and the circuit board (control section) 24 are arranged can be ensured.

[0044] In addition, a press-type power switch 2111 that switches on / off of a power supply and a press-type level switch 2112 that adjusts a power-on level at the time of use of the beauty device 10 are formed in a lower side portion of the front housing 211 (a portion that becomes the grip portion 20a). In the present embodiment, as the power switch, the press-type power switch 2111 is exemplified, but as long as it is a switch that can turn on / off the power supply, it can also be a slide-type or other switch. Similarly, as the level switch, the press-type level switch 2112 is exemplified, but as long as it is a switch that can adjust the power-on level, it can also be a slide-type or other switch.

[0045] Thus, in the present embodiment, when the user or the like holds the beauty device 10 for use in a usual method, various switches are formed in a front surface portion (front surface portion) touched by the thumb of the holder. By so doing, it is possible to easily perform the operation of the switches in a state of holding the beauty device 10.

[0046] Further, as the use mode of the beauty device 10, for example, a beauty mode that adopts the EMS described above, an iontophoresis mode that adopts the iontophoresis described later, and the like can be exemplified. Therefore, for example, it can be configured such that, each time the power switch 2111 is operated, the order of on of the power supply, selection of the beauty mode that adopts the EMS, selection of the iontophoresis mode, and off of the power supply are sequentially switched.

[0047] Further, it can be configured such that, when the level switch 2112 is operated in a state of selecting the beauty mode that adopts the EMS, the voltage of the first electric output output from the electrode pin 311 can be selected in a range of 7 V to 18 V. At this time, the circuit board (control section) 24 controls the first electric output so that the frequency (output electric stimulus frequency) is in a range of 1 Hz or more and less than 10 kHz. Further, it can be configured such that, when the level switch 2112 is operated, the frequency of the first electric output output from the electrode pin 311 can be selected in a range of 1 Hz or more and less than 10 kHz.

[0048] Further, when the level switch 2112 is operated in a state in which the iontophoresis mode is selected, the voltage of the second electric output outputted from the electrode pin 311 can be selected within a range of 7 V to 18 V. At this time, the circuit board (control section) 24 controls the second electric output so that the frequency (output electric stimulus frequency) is within a range of 1 kHz or more and less than 10 kHz. Further, it can be configured so that when the level switch 2112 is operated in a state in which the iontophoresis mode is selected, the frequency of the second electric output outputted from the electrode pin 311 can be selected within a range of 1 kHz or more and less than 10 kHz.

[0049] Further, in the present embodiment, an LED cover 26 is provided between the front case 211 and the inner cover 22, and light emitted from an LED (not shown) mounted to the circuit board (control section) 24 is made to pass through a predetermined light path by the LED cover 26. The LED (not shown) is used when the on state of the power supply, the state of the power supply level is displayed on the main case 21.

[0050] Further, in the present embodiment, a plug base 27 holding a plug terminal 271 is mounted to the battery base 25, and external power can be supplied from the plug terminal 271 to the battery 251, the circuit board (control section) 24, and the like. Further, the plug terminal 271 is covered by a plug cover 28 mounted to the main case 21 in an openable and closable manner.

[0051] On the other hand, a second housing space 2122 is formed in the upper portion of the rear case 212, and the electrode section 30 is housed in the second housing space 2122.

[0052] In the present embodiment, the electrode section 30 is housed in the second housing space 2122 by forming an electrode block 31 in which various components are integrated, and housing the electrode block 31 in the second housing space 2122. In this way, in the present embodiment, the electrode section 30 is provided with the electrode block 31 in which various components are integrated.

[0053] Further, the front case 211 and the rear case 212 are joined in a state in which the battery 251, the circuit board (control section) 24, and the battery base 25 are housed in the first housing space 2121, and the electrode block 31 is housed in the second housing space 2122.

[0054] A head cover 213 in which a plurality of through holes 2131 are formed is provided in the upper portion of the front case 211. When the front case 211 and the rear case 212 are joined, a plurality of electrode pins 311 are inserted into the corresponding through holes 2131.

[0055] In this manner, the electrode unit 30, excluding the electrode group 30a, the battery 251 that supplies power to the electrode unit 30, the battery base 25 that holds the battery 251, and the circuit board (control unit) 24 that controls power on / off are housed within the cavity of the main body case 21. Furthermore, the electrode unit 30 is provided on the main body 20 with the plurality of electrode pins 311 that constitute the electrode group 30a protruding toward the outside (front) of the main body 20.

[0056] Therefore, in this embodiment, the front surface 213a of the head cover portion 213 serves as the head surface of the head 20b.

[0057] The head cover 213 may be integrally formed with the front housing 211 or may be separate from the front housing 211 and attached to the front housing 211. The front wall of the electrode block 31 may also serve as the head cover 213.

[0058] In this embodiment, if Figure 10 As shown, the electrode block 31 includes a plurality of electrode pins 311 and a conductive plate (conductor) 312 electrically connected to the circuit board (control unit) 24. The electrode block 31 also includes an elastic conductor electrically connecting the conductive plate (conductor) 312 and the electrode pins 311.

[0059] In this embodiment, the coil spring 313 inserted into the electrode pin 311 from one axial end thereof electrically connects the conductive plate (conductor) 312 and the electrode pin 311. Thus, in this embodiment, the coil spring 313 serves as an elastic conductor.

[0060] like Figure 11 As shown, the electrode pin 311 includes a columnar, large-diameter portion 3111 located at the other axial end of the electrode pin 311, and a reduced-diameter portion 3112 located at one axial end and having a smaller diameter than the large-diameter portion 3111. The tip of the reduced-diameter portion 3112 is inserted into a through-hole 3121 formed in the conductive plate (conductor) 312. This arrangement allows the conductive plate (conductor) 312 to suppress movement of the multiple electrode pins 311 in the left-right direction (a direction intersecting the axial direction).

[0061] Further, a step portion 3113 is formed at the boundary between the large diameter portion 3111 and the reduced diameter portion 3112, and the step portion 3113 functions as a spring seat that supports the coil spring 313. That is, the coil spring 313 is interposed between the step portion 3113 and the conductive plate (conductive body) 312. By doing so, the conductive plate (conductive body) 312 and the electrode pin 311 are electrically connected by the coil spring 313. Further, the coil spring 313 exerts a force on the electrode pin 311 in the axial direction. In this way, in the present embodiment, the beauty device (brush-type beauty device) 10 has the conductive plate (conductive body) 312 that is a common base portion of the electrode pins (electrodes of the plurality of pin bodies) 311. Further, the conductive plate (conductive body) 312 is electrically connected to the circuit board (control portion) 24 that is the current control portion. Moreover, the conductive plate (conductive body) 312 and the electrode pins (electrodes of the plurality of pin bodies) 311 are electrically connected by the coil spring 313 that is inserted in the axial direction.

[0062] Further, in the present embodiment, the electrode block 31 has an elastic structure body 316 that holds the electrode pins 311.

[0063] The elastic structure body 316 has a main body portion 3161 that holds the electrode pins 311. In the present embodiment, one elastic structure body 316 holds all of the electrode pins 311.

[0064] At this time, each of the electrode pins 311 is held to the elastic structure body 316 in a state of penetrating the elastic structure body 316. The main body portion 3161 has a wall portion 31611 that extends in the axial direction of the electrode pins 311. By the wall portion 31611 being in close contact with the surface of the large diameter portion 3111, each of the electrode pins 311 is held to the elastic structure body 316. By doing so, the reduced diameter portion 3112 side of each of the electrode pins 311 is covered by one elastic structure body 316.

[0065] Such a structure can be obtained by holding the electrode pins 311 to the elastic structure body 316 by insert molding. Alternatively, the electrode pins 311 can be held by being press-fitted into through holes formed in the elastic structure body 316.

[0066] Further, the elastic structure body 316 can be made to have conductivity. In this way, since the elastic structure body 316 can function as an elastic conductor, it is not necessary to use the coil spring 313, and simplification of the structure can be achieved.

[0067] Further, the electrode block 31 includes a base 314 and a frame cover 315 that constitute the outer shape of the electrode block 31.

[0068] A guide hole 3141 is formed in the base 314. The guide hole 3141 is arranged so as to match the through hole 3121 formed in the conductive plate (conductive body) 312, is inserted into the through hole 3121, and receives the tip end side of the reduced diameter portion 3112. By doing so, the movement of the electrode pin 311 in the axial direction is guided by the guide hole 3141. In addition, the movement of the electrode pin 311 in a direction other than the axial direction is suppressed by the guide hole 3141. By doing so, even in the case where the cosmetic device 10 is used while being attached to various parts of the skin, the electrode pin 311 does not bend, and thus the contactability of the electrode pin 311 with the skin of the user can be ensured.

[0069] In addition, a through hole 3151 is also formed in the frame cover 315, and the large diameter portion 3111 of the electrode pin 311 is inserted into the through hole 3151. By doing so, the electrode block 31 in which the large diameter portions 3111 of a plurality of electrode pins 311 protrude to the outside of the frame cover 315 is formed.

[0070] In the present embodiment, when the base 314 and the frame cover 315 are joined, the peripheral portion 3162 of the elastic structure 316 is gripped by the base 314 and the frame cover 315. Specifically, the elastic structure 316 has an engaging piece 31621 formed in the peripheral portion 3162 thereof. The base 314 has an engaging groove 3142 formed in the periphery thereof. Before the base 314 and the frame cover 315 are joined, the engaging piece 31621 is engaged with the engaging groove 3142. Furthermore, by joining the base 314 and the frame cover 315 in a state in which the engaging piece 31621 is engaged with the engaging groove 3142, the peripheral portion 3162 of the elastic structure 316 is gripped by the base 314 and the frame cover 315.

[0071] By doing so, the space in which the conductive plate (conductive body) 312, the coil spring 313, and the reduced diameter portion 3112 of the electrode pin 311 are arranged is sealed by the elastic structure 316. In this way, in the present embodiment, a waterproof structure is formed in the electrode block 31 in which the contact portions are formed.

[0072] Furthermore, as Figure 12 indicated, it is also possible to use two (a plurality of) elastic structures 316 to hold the electrode pin 311 to each of the elastic structures 316. In this case, a waterproof structure can be formed by each of the elastic structures 316. Furthermore, even in the case where the elastic structure 316 has conductivity, it is possible to provide a structure in which a plurality of electrode pins 311 have two polarities (a structure in which an electrode pin 311 that becomes a positive electrode and an electrode pin 311 that becomes a negative electrode exist).

[0073] Furthermore, the portion of the electrode block 31 other than the large diameter portion 3111 that protrudes to the outside of the frame cover 315 is arranged in the hollow formed in the main body case 21.

[0074] Thus, in the present embodiment, the elastic structure 316 for waterproofing is arranged inside the main body portion 20 in a state of holding the electrode pin 311. In other words, the electrode pin (plurality of pin bodies) 311 is held by the elastic structure 316 arranged inside the main body portion 20.

[0075] Further, the beautification of the skin by EMS using the cosmetic device 10 of such a structure can be performed, for example, by the following method.

[0076] First, the polarity of the plurality of electrode pins 311 is divided into two. That is, the polarity of a part of the plurality of electrode pins 311 is made positive, and the polarity of the remaining electrode pins 311 is made negative. For example, the polarity of the electrode pins 311 on the left half of the plurality of electrode pins 311 is made positive, and the polarity of the electrode pins 311 on the right half of the plurality of electrode pins 311 is made negative. Figure 3 The polarity of the electrode pins 311 on the left half of the plurality of electrode pins 311 is made positive, and the polarity of the electrode pins 311 on the right half of the plurality of electrode pins 311 is made negative.

[0077] Further, the plurality of electrode pins 311 having two polarities are brought into contact with the skin of the user and energized. At this time, the circuit board (control portion) 24 controls the first electric output so that the frequency is in a range of 1 Hz or more and less than 10 kHz. By doing so, the skin of the user is subjected to an electric stimulus by the current flowing through the skin of the user between the opposite poles, and an EMS stimulus that causes the muscle of the user to contract is imparted.

[0078] In addition, in the present embodiment, the panel electrode (second electrode) 2123 is formed in the portion of the rear side housing 212 that becomes the grip portion 20a in a manner exposed from the rear side housing 212. Further, the circuit board (control portion) 24 controls the second electric output output to between the electrode pin 311 and the panel electrode (second electrode) 2123. In this way, in the present embodiment, the panel electrode (second electrode) 2123 is arranged on the back surface of the main body portion 20. Further, the circuit board (control portion) 24 has a function as a current control portion that controls the current supplied to the electrode pin (electrode of the plurality of pin bodies) 311, and is configured to be able to output electricity between the panel electrode (second electrode) 2123 arranged on the back surface of the main body portion 20 and the electrode pin (electrode of the plurality of pin bodies) 311. By doing so, it is possible to perform the beautification of the iontophoresis that causes a cosmetic or the like to penetrate into the skin.

[0079] The beautification of the iontophoresis can be performed, for example, by the following method.

[0080] First, the plurality of electrode pins 311 are all made to be the same polarity (positive or negative). Also, the polarity of the panel electrode (second electrode) 2123 is made to be different from that of the electrode pins 311 (negative or positive). Also, in a state where the panel electrode (second electrode) 2123 is held, the plurality of electrode pins 311 are brought into contact with the skin, and current is passed therethrough. At this time, the circuit board (control section) 24 controls the second electric output so that the frequency is in a range of 1 kHz or more and less than 10 kHz. By doing so, a current in which the user's body becomes a part of the circuit is generated, and the permeation effect of the agent such as the cosmetic into the skin can be improved.

[0081] Thus, in the present embodiment, the electrode pins (electrodes of the plurality of pin bodies) 311 are configured to be able to pass currents having different characteristics to the user's skin, respectively. Specifically, the circuit board (control section) 24 as the current control section is able to control in a manner in which a different polarity structure is formed between the electrode groups in the electrode pins (electrodes of the plurality of pin bodies) 311 at the time of the beauty treatment. In addition, the circuit board (control section) 24 as the current control section is able to control in a manner in which a different polarity structure is formed between the panel electrode (second electrode) 2123 disposed on the back surface of the main body section 20 and the electrode pins (electrodes of the plurality of pin bodies) 311.

[0082] At this time, the circuit board (control section) 24 as the current control section can be able to control the current flowing through the electrode pins (electrodes of the plurality of pin bodies) 311 one by one (may be two or more).

[0083] Also, in the present embodiment, the beauty device 10 is provided with the accessory 40 which is attached to and detached from the main body section 20 in a detachable manner.

[0084] In the present embodiment, the accessory 40 is provided with an accessory base 41. The accessory base 41 includes a top wall 411 in which a top surface 411a becomes a head surface, and a peripheral wall 412 which is provided continuously with the periphery of the top wall 411. Also, as shown in FIG. 9, a fitting protrusion 4121 is formed in the peripheral wall 412. By fitting the fitting protrusion 4121 with the fitting hole 2132 formed in the head cover section 213 in a releasable manner, the accessory 40 is attached to the main body section 20. Figure 14

[0085] ​In addition, two flat electrodes (3rd electrodes: one or more electrodes) 42 are formed in the top wall 411 so as to be exposed from the top surface (outer surface) 411a. Further, by bringing the flat electrodes (3rd electrodes) 42 into contact with the skin in a state where the attachment 40 is attached to the main body 20, it is possible to perform the cosmetic treatment of the skin. In addition, in the present embodiment, the top surface (outer surface) 411a as the head surface has an inclined angle with respect to the main body 20. By doing so, even in a state where the user brings the flat electrodes (3rd electrodes) 42 into contact with the skin, it is easy to move the cosmetic treatment device 10. In this way, since it is possible to maintain the state where the flat electrodes (3rd electrodes) 42 are in contact with the skin, it is possible to stably bring the flat electrodes (3rd electrodes) 42 into contact with the skin.

[0086] Further, in the present embodiment, the attachment 40 is provided with a conductive rubber (conductive member) 43 which is disposed inside the attachment 40 and is electrically connected to the flat electrodes (3rd electrodes) 42. Further, in a state where the attachment 40 is attached to the main body 20, the electrode pin 311 is in abutment with the conductive rubber (conductive member) 43, and the conductive rubber (conductive member) 43 and the electrode pin 311 are electrically connected. That is, when the attachment 40 is attached to the main body 20, the flat electrodes (3rd electrodes) 42 disposed in the attachment 40 are electrically connected to the main body 20 via the conductive rubber (elastic body having conductivity) 43.

[0087] Preferably, the electrode pin 311 is pressed inward when the electrode pin 311 is in abutment with the conductive rubber 43. In this way, since the electrode pin 311 is energized so as to push up the conductive rubber (conductive member) 43 when the attachment 40 is attached to the main body 20, it is possible to improve the reliability of the electrical connection, and on this basis, it is also possible to achieve the miniaturization of the cosmetic treatment device 10 in a state where the attachment 40 is attached.

[0088] In addition, preferably, two or more electrode pins 311 are in abutment with the conductive rubber (conductive member) 43. In other words, preferably, when the attachment 40 is attached to the main body 20, the electrode pin (electrode of the plurality of pin bodies) 311 is electrically connected to the conductive rubber (elastic body having conductivity) 43 disposed in the attachment 40. By doing so, it is also possible to improve the reliability of the electrical connection.

[0089] Further, the conductive member does not necessarily have elasticity, and a metal can be used to form the conductive member.

[0090] [Effects]

[0091] Hereinafter, the characteristic structure of the cosmetic treatment device shown in the above embodiments and the effects thereof will be described.

[0092] (Technology 1) The cosmetic device 10 shown in the above-described embodiment and its variations includes the electrode section 30 having a plurality of electrode pins 311, and the main body section 20 that holds the electrode section 30 in a state where the electrode pins 311 project outward. The cosmetic device 10 further includes the elastic structure 316 that is arranged inside the main body section 20 in a state of holding the electrode pins 311.

[0093] Thus, if the electrode pins 311 are held by the elastic structure 316, the electrode pins 311 can be given mobility in the axial direction (the projecting direction of the electrode pins). As a result, the plurality of electrode pins 311 can be brought into contact with the skin along the shape of the skin. That is, the plurality of electrode pins 311 can be brought into stable contact with the skin regardless of the shape of the skin. As a result, even if the cosmetic device 10 is used at various parts of the skin, the cosmetic treatment of the skin can be performed more effectively. The elastic structure 316 can also enable the plurality of electrode pins 311 to move individually.

[0094] In addition, the elastic structure 316 that holds the electrode pins 311 can be arranged inside the main body section 20. Thus, the inside of the main body section 20 can be made into a waterproof structure by the elastic structure 316, and thus the waterproof property of the electrode section 30 can be ensured.

[0095] Thus, by arranging the elastic structure 316 that holds the electrode pins 311 inside the main body section 20, the waterproof property of the electrode section 30 can be ensured while giving the electrode pins 311 mobility in the axial direction (the projecting direction of the electrode pins).

[0096] In addition, by the elastic structure 316 being present inside the main body section 20, it is also possible to suppress the case where a user or the like comes into contact with the elastic structure 316. Thus, even if the user or the like uses the cosmetic device 10 in an unintended manner, it is possible to more reliably suppress the case where the elastic structure 316 is broken. As a result, it is possible to more reliably maintain the waterproof structure constituted by the elastic structure 316.

[0097] Furthermore, since it is possible to suppress the case where the elastic structure 316 comes into contact with the skin, hair, or the like when the cosmetic device 10 is used, it is possible to suppress the case where the skin touch feeling at the time of use deteriorates, and a comfortable feeling of use can be obtained.

[0098] In addition, when the cosmetic treatment of the skin is performed, it is sometimes performed in a state where various agents are applied to the skin. Even in such a case, by using the cosmetic device 10 shown in the above-described embodiment and its variations, it is possible to suppress the case where the elastic structure 316 swells due to the agents. Thus, it is also possible to suppress the deterioration of the waterproof property of the electrode section 30 caused by the swelling of the elastic structure 316.

[0099] Thus, by housing the waterproof elastic structure 316 in the main body 20, the waterproof property of the electrode portion 30 can be more reliably ensured, and thus not only the skin care of the skin wetted with water or applied with an agent can be performed, but also the skin care can be performed while washing the hair in a bathroom or the like. The skin care device 10 can be used in various environmental conditions.

[0100] Thus, if the skin care device 10 shown in the above embodiment and its modification is adopted, the skin care can be more effectively performed while optimizing the use convenience.

[0101] (TECHNICAL 2) In addition, according to the above (TECHNICAL 1), the plurality of electrode pins 311 can be held in the elastic structure 316 in a state of penetrating the elastic structure 316.

[0102] Thus, the space in which the electrode pins 311 are arranged can be separated into one side (the side in contact with the skin) and the other side (the position of electrical connection) by the elastic structure 316. That is, the configuration can be such that one side (the side in contact with the skin) of the electrode pins 311 is exposed to the outside, and the other side (the position of electrical connection) is sealed by the elastic structure 316. Thus, on the basis of being able to more easily obtain the waterproof structure of the electrode portion 30, the simplification of the structure can also be sought.

[0103] (TECHNICAL 3) In addition, according to the above (TECHNICAL 1) or (TECHNICAL 2), the skin care device 10 can include a circuit board (control portion) 24 provided inside the main body 20 and capable of controlling the first electric output output by the plurality of electrode pins 311. In addition, the skin care device 10 can include a conductive plate (conductive body) 312 electrically connected to the circuit board (control portion) 24 and an elastic conductor electrically connecting the conductive plate (conductive body) 312 and the plurality of electrode pins 311.

[0104] Thus, by electrically connecting the conductive plate (conductive body) 312 and the electrode pins 311 using the elastic conductor, the elastic conductor can be deformed (elastically deformed) in a manner of following the movement of the electrode pins 311 given with the mobility in the axial direction (the protruding direction of the electrode pins). Thus, even in the case where the electrode pins 311 are given with the mobility in the axial direction (the protruding direction of the electrode pins), the reliability of the electrical connection of the conductive plate (conductive body) 312 and the electrode pins 311 can be further improved.

[0105] (TECHNICAL 4) In addition, according to the above (TECHNICAL 3), the elastic conductor can be a plurality of coil springs 313. The plurality of electrode pins 311 can be respectively inserted into corresponding one of the plurality of coil springs 313 from the one end side in the axial direction.

[0106] Thus, the electrode pin 311 can be given movability in the axial direction (the protruding direction of the electrode pin) by the coil spring 313, and the electrically conductive plate (electrically conductive body) 312 and the electrode pin 311 can be electrically connected.

[0107] (TECHNICAL 5) In addition, according to any one of the above-described (TECHNICAL 3) or (TECHNICAL 4), the elastic conductor can be an elastic structure body 316 having electrical conductivity.

[0108] Thus, the electrically conductive plate (electrically conductive body) 312 and the electrode pin 311 can be electrically connected without using the coil spring 313. That is, a conductor for electrically connecting the electrode pin 311 and the electrically conductive plate (electrically conductive body) 312 does not need to be separately provided. As a result, it is possible to seek simplification of the structure of the electrode portion 30.

[0109] (TECHNICAL 6) In addition, according to any one of the above-described (TECHNICAL 3) to (TECHNICAL 5), the circuit board (control portion) 24 can control the first electric output so that the frequency is in a range of 1 Hz or more and less than 10 kHz.

[0110] Thus, it is possible to more effectively perform the skin treatment using the beauty device 10. Such control is a particularly effective means when the skin treatment is performed by EMS that is normally performed at a frequency from a low frequency to a medium frequency.

[0111] (TECHNICAL 7) In addition, according to any one of the above-described (TECHNICAL 3) to (TECHNICAL 6), the main body portion 20 can have a grip portion 20a in which a panel electrode (second electrode) 2123 is formed. Also, the circuit board (control portion) 24 can control a second electric output that is output between the plurality of electrode pins 311 and the panel electrode (second electrode) 2123.

[0112] Thus, it is possible to use the beauty device 10 for various purposes. As a result, it is possible to provide a beauty device 10 that is more convenient to use.

[0113] (TECHNICAL 8) In addition, according to the above-described (TECHNICAL 7), the circuit board (control portion) 24 can control the second electric output so that the frequency is in a range of 1 kHz or more and less than 10 kHz.

[0114] Thus, it is possible to more effectively perform the skin treatment using the beauty device 10. Such control is a particularly effective means when the skin treatment is performed by iontophoresis (ion introduction) that does not want to apply too much stimulation to the skin.

[0115] (Technology 9) According to any one of the above (Technology 1) to (Technology 8), the cosmetic device 10 can also be provided with the accessory 40 that is attached to the main body 20 in a detachable manner. In addition, the accessory 40 can be provided with the flat plate electrode (third electrode) 42 that is exposed from the top surface (outer surface) 411a of the accessory 40. Also, the accessory 40 can be provided with the conductive rubber (conductive member) 43 that is disposed on the inner side of the accessory 40 and is electrically connected to the flat plate electrode (third electrode) 42. Also, the conductive rubber (conductive member) 43 and the plurality of electrode pins 311 can be electrically connected in a state in which the accessory 40 is attached to the main body 20.

[0116] In this way, since the cosmetic device 10 can be used in various methods, the cosmetic device 10 can be provided with better convenience of use.

[0117] In addition, by electrically connecting the conductive rubber (conductive member) 43 and the electrode pins 311 in a state in which the accessory 40 is attached to the main body 20, it is not necessary to provide a contact portion that is connected to the flat plate electrode (third electrode) 42 in the main body 20. As a result, it is possible to reduce the cost while pursuing the simplification of the structure of the cosmetic device 10.

[0118] In addition, since the electrode pins 311 that are given movability in the axial direction (protruding direction of the electrode pins) are used as the contact portion that is connected to the flat plate electrode (third electrode) 42, it is possible to more reliably ensure the contact pressure of the conductive rubber (conductive member) 43 and the electrode pins 311. Therefore, it is possible to further improve the connection reliability of the conductive rubber (conductive member) 43 and the electrode pins 311. Also, since it is possible to suppress the increase in the height in the axial direction (protruding direction of the electrode pins) when the accessory 40 is attached to the main body 20, it is possible to make the size of the cosmetic device 10 in which the accessory 40 is attached to be more compact.

[0119] (Technology 10) In addition, according to the above (Technology 9), the conductive rubber (conductive member) 43 can have elasticity.

[0120] In this way, since it is possible to suppress the damage of the electrode pins 311 in the case in which the attachment and detachment of the accessory 40 are repeated, it is possible to ensure the usability of the accessory 40 for a long period of time.
