Problems to be solved by the invention

In the field of beauty devices, not only excellent performance and function but also excellent appearance and beauty are often required. However, in the cosmetic device in which the surface of the handle is covered with the electrode as in patent document 1, dirt such as a mark on the hand of the user is likely to adhere to the surface of the electrode when the user holds the handle. If such dirt is visually recognized after the beauty appliance is used, the aesthetic appearance of the appearance may be impaired.

In order to make the stains attached to the electrodes less noticeable, a method of reducing the electrode area is considered. However, for example, in the case where the electrode is configured as a member separate from the handle as in patent document 2, since the size of the electrode is reduced, there is a possibility that the operability is deteriorated such as an operation of attaching the electrode to the handle and an operation of electrically connecting the electrode to a circuit.

The present invention has been made in view of such a background, and an object thereof is to provide a beauty device which is easy to assemble and has excellent appearance and beauty.

Means for solving the problems

One aspect of the present invention is a beauty device including: an electrical component; and a housing having a hollow portion for accommodating the electric component, wherein,

the housing has:

a first member having electrical insulation;

a second member that is joined to the first member so as to provide the hollow portion between the second member and the first member, and that has conductivity; and

a third member that covers a part of an outer surface of the second member and has electrical insulation,

the second member has an electrode portion composed of at least a part of an exposed portion exposed without being covered by the third member,

the electrode portion is electrically connected to the electrical component.

Effects of the invention

The beauty device comprises: the first member; the second member engaged with the first member; the third member that covers a part of an outer surface of the second member; and the electrode portion that is formed of at least a part of the exposed portion of the second member. Therefore, by changing the shape of the third member, the position and shape of the electrode portion can be easily changed to various forms. Therefore, the electrode unit of the cosmetic device can be disposed at a position where dirt or the like is adhered to the electrode unit and the dirt or the like is less likely to be conspicuous. Further, it is also easy to dispose the electrode unit at an appropriate position according to the use of the cosmetic device.

The electrode portion is formed of at least a part of the exposed portion of the second member. Therefore, it is not necessary to reduce the size of the members constituting the electrode unit in order to make dirt or the like less noticeable as in the conventional cosmetic device. As a result, the deterioration of the operability of the assembly operation of the beauty device can be easily avoided.

The hollow portion is a space surrounded by the first member and the second member. Therefore, when the sealing member for preventing sweat, moisture, and the like from entering from the external space into the hollow portion is provided, the number of sealing members can be reduced.

As described above, the cosmetic device can dispose the electrode unit at a position where dirt or the like is adhered to make the dirt or the like less noticeable. Therefore, the dirt adhering to the electrode portion is less conspicuous and has excellent appearance. In addition, the beauty device can easily avoid the deterioration of the operability of the assembling operation, thereby being easy to assemble.

Detailed Description

In the cosmetic device, the electrode unit may be disposed along a boundary between the first member and the second member in an outer surface of the casing. In this case, since the electrode portion is formed linearly along the boundary, dirt or the like adhering to the electrode portion can be made less conspicuous. In this case, the shapes of the second member and the third member can be further simplified, and the operability of the operation of attaching the third member to the second member can be further improved.

The housing may have a rod shape, and the first member and the second member may extend in a longitudinal direction of the housing. In this case, the shape of the first member and the second member can be simplified, and the operability of the operation of disposing the electric component between the first member and the second member can be further improved.

In the above case, it is preferable that the electrode portion is further disposed along a boundary between the first member and the second member. In this case, since the electrode portion can be formed linearly over a wide range in the longitudinal direction of the case, the hand of the user and the electrode portion are more likely to come into contact when the user grips the case. In this case, the electrode portions may be continuously disposed on both side surfaces of the housing along the longitudinal direction. Therefore, even in the case of an unbalanced gripping method in which the user grips, for example, the end portion of the housing in the longitudinal direction, the hand of the user easily comes into contact with the electrode portion. As a result, the usability of the beauty device can be further improved.

Further, in this case, since the width of the electrode portion can be reduced, as described above, an effect of making dirt and the like adhering to the electrode portion less noticeable and an effect of further improving the operability of the operation of attaching the third member to the second member can be obtained.

The second member may have a fastening hole in a portion covered with the third member, and the first member may be fastened to the second member by a screw inserted through the fastening hole. In this case, the fastening hole and the screw can be covered and shielded by the third member. Therefore, the beauty of the beauty device can be further improved.

In this case, the gap can be easily reduced at the contact portion between the first member and the second member. Therefore, sweat, moisture, and the like can be prevented from entering the hollow portion from the contact portion between the two.

Further, the housing may have a seal member interposed between the first member and the second member. In this case, it is possible to prevent sweat, moisture, and the like from entering the hollow portion from the contact portion between the first member and the second member. As the sealing member, a known sealing member such as a rubber gasket or a rubber sheet can be used.

The second member may be covered with a chromium plating film having conductivity. In this case, a high glossiness can be easily imparted to the electrode portion. As a result, the beauty of the beauty device can be further improved.

A conductive member having conductivity may be interposed between the second member and the electrical member, and the second member and the electrical member may be electrically connected via the conductive member. In this case, the second member and the electric component can be electrically connected by a simple operation of bringing the current-carrying member into contact with the inner surface of the second member. Therefore, the operability of the assembly operation of the beauty device can be further improved.

An embodiment of the beauty device will be described with reference to the drawings. As shown in fig. 4, the beauty device 1 includes: an electrical component 12; and a case 2 having a hollow portion 25 (see fig. 6) for accommodating the electric component 12. As shown in fig. 1 to 4, the housing 2 includes: a first member 21 having electrical insulation; a second member 22 having conductivity; a third member 23 having electrical insulation properties; and an electrode portion 14. As shown in fig. 6, the second member 22 is engaged with the first member 21. Further, a hollow portion 25 is formed between the first member 21 and the second member 22. As shown in fig. 1 to 3, the third member 23 covers a part of the outer surface of the second member. The second member 22 has the electrode portion 14, and the electrode portion 14 is formed of at least a part of an exposed portion which is not covered with the third member 23 but is exposed. The electrode portion 14 is electrically connected to the electrical component 12.

As shown in fig. 1 to 3, the housing 2 in this example has a rod shape. The first member 21 and the second member 22 extend in the longitudinal direction of the housing 2.

In the beauty device 1 of this embodiment, the sectional shape of the case 2 in the longitudinal direction is substantially elliptical. As shown in fig. 2 and 3, the center portion 20 of the housing 2 in the longitudinal direction is slightly thinner than both end portions.

A flange portion 223 that abuts the outer peripheral edge of the first member is formed on the outer peripheral edge of the second member 22 over the entire periphery thereof. The third member 23 in this example extends in the longitudinal direction of the housing 2 so that the flange portion 223 of the second member 22 is exposed to the outer surface of the housing 2. The outer surface of the flange portion 223 exposed between the first member 21 and the third member 23 constitutes the electrode portion 14. The electrode portion 14 is disposed along a boundary between the first member 21 and the second member 22 in the outer surface of the case 2.

As shown in fig. 4, the second member 22 has a fastening hole 224 at a portion covered by the third member 23. The first member 21 is fastened and coupled to the second member 22 by a screw 221 (see fig. 6) inserted through the fastening and coupling hole 224.

A projection (not shown) for engaging the third member 23 with the second member 22 is formed on the outer peripheral edge of the third member 23. In addition, an engaged portion 225 (see fig. 4) for accommodating the projection is formed along the flange portion 223 in the second member 22. Although not shown, in a state where the third member 23 and the second member 22 are engaged with each other, the protruding portion of the third member 23 is accommodated in the engaged portion 225 (see fig. 4) of the second member 22.

As shown in fig. 6, a hollow portion 25 is formed between the first member 21 and the second member 22, and the hollow portion 25 accommodates components for operating the beauty device 1. As shown in fig. 4 to 6, a rubber gasket 211 as a sealing member is interposed between the outer peripheral edge of the first member 21 and the flange portion 223 of the second member 22. As shown in fig. 6, a rubber packing 222 is also interposed between the second member 22 and the screw 221 for fastening and connecting the second member to the first member 21. The beauty device 1 is constituted by: the rubber packings 211 and 222 can prevent moisture from entering the hollow portion 25 from between the first member 21 and the second member 22.

The first member 21 and the third member 23 are made of ABS resin having electrical insulation. The second member 22 is made of ABS resin covered with a chromium plating film having conductivity.

As shown in fig. 4 and 6, the electric component 12 is disposed in the hollow portion 25. Further, a conductive member 124 having conductivity is interposed between the second member 22 and the control substrate 121, and the electrode portion 14 and the control substrate 121 are electrically connected via the conductive member 124 and the second member 22. More specifically, as shown in fig. 4, the electric component 12 in this example is disposed at the center in the longitudinal direction of the housing 2. The electrical component 12 includes: a control substrate 121; and a power supply unit 122 that supplies power to the control board 121. The control board 121 and the power supply unit 122 are engaged with each other.

Specifically, the energizing member 124 in this example is a spring made of metal. As shown in fig. 4 to 6, one end of the current-carrying member 124 is connected to the control board 121, and the other end is in contact with the chromium plating film provided on the inner surface of the second member 22. Thereby, the electrode portion 14 is electrically connected to the control board 121 via the current-carrying member 124 and the chromium plating film on the surface of the second member 22.

The operation and effect of the beauty device of this example will be described. The beauty device 1 includes: a first member 21; a second member 22 engaged with the first member 21; a third member 23 covering a part of the outer surface of the second member 22; and an electrode portion 14 formed of at least a part of the exposed portion of the second member 22. Therefore, by changing the shape of the third member 23, the position and shape of the electrode portion 14 can be easily changed to various forms. Therefore, the cosmetic device 1 can dispose the electrode portion 14 at a position where dirt or the like is less noticeable when the dirt or the like adheres thereto.

The electrode portion 14 is formed of at least a part of the exposed portion of the second member 22. Therefore, it is not necessary to reduce the size of the members constituting the electrode unit in order to make dirt or the like less noticeable as in the conventional cosmetic device. As a result, the operability of the assembly operation of the beauty appliance 1 can be easily prevented from deteriorating.

The electrode portion 14 is arranged along a boundary between the first member 21 and the second member 22 in the outer surface of the housing 2. This makes it possible to make the stains and the like adhering to the electrode portion 14 less noticeable. In this case, the shapes of the second member 22 and the third member 23 can be further simplified, and the operability of the operation of attaching the third member 23 to the second member 22 can be further improved.

The housing 2 has a rod shape, and the first member 21 and the second member 22 extend in the longitudinal direction of the housing 2. Therefore, the shapes of the first member 21 and the second member 22 can be simplified, and the operability of the operation of disposing the electric components between the first member 21 and the second member 22 can be further improved.

The electrode portion 14 in this example is formed in a linear shape over a wide range in the longitudinal direction of the housing 2. Therefore, when the user grips the housing 2, the hand of the user and the electrode portion 14 become more easily contacted. As a result, the usability of the beauty device 1 can be further improved.

The second member 22 has a fastening hole 224 at a portion covered with the third member 23, and the first member 21 is fastened to the second member 22 by a screw 221 inserted through the fastening hole 224. Therefore, the fastening hole 224 and the screw 221 can be covered and shielded by the third member 23. As a result, the beauty of the beauty device 1 can be further improved.

The second member 22 is covered with a chromium plating film having conductivity. Therefore, a high glossiness can be easily imparted to the electrode portion 14, and the appearance of the cosmetic device 1 can be further improved.

An electrically conductive member 124 having electrical conductivity is interposed between the second member 22 and the electrical component 12, and the second member 22 and the electrical component 12 are electrically connected via the electrically conductive member 124. Therefore, the second member 22 and the electric component 12 can be electrically connected by a simple operation of bringing the conductive member 124 into contact with the inner surface of the second member 22. As a result, the operability of the assembly operation of the beauty appliance 1 can be further improved.

As described above, the cosmetic device 1 can dispose the electrode portion 14 at a position where dirt or the like is adhered to make the dirt or the like less noticeable. Therefore, the dirt adhering to the electrode portion 14 is less likely to be conspicuous and has excellent aesthetic properties. Further, the beauty device 1 can be easily assembled by avoiding deterioration of workability in the assembling operation.

As shown in fig. 5 and 7, the motor base 51 can be coupled to the first member 21 in a relatively displaceable state by attaching the E-ring 241 to the locking groove 242. As described above, the coupling portion 11 in this example includes: an elastic member 53 held by the plate-like portion 511 of the motor base 51; a guide bar 24 provided to the first member 21; and an E-ring 241 attached to the locking groove 242. The beauty device 1 of the present embodiment has three connecting portions 11. Each coupling portion 11 has: a guide bar 24 provided to the housing 2; and an elastic member 53 held by the motor base 51, and the guide rod 24 penetrates the elastic member 53.

The motor cover 52 is fastened and coupled to the motor receiving portion 512 by screws 521 shown in fig. 5. The vibration motor 4 is held between the motor cover 52 and the motor receiving portion 512. The motor cover 52 of this example is made of ABS resin.

The vibration motor 4 in this example is a cylinder (cylinder) type vibration motor 4. The vibration motor 4 is configured to: the axial direction 420 of the rotary shaft 42 is along the longitudinal direction of the housing 2. The eccentric weight 41 of the vibration motor 4 is disposed on the front side X1 in the front-rear direction X.

As shown in fig. 5 and 6, two of the three connecting portions 11 (11 a, 11 b) 11a are disposed on the front X1 side in the axial direction 420 of the rotating shaft 42 with respect to the center of gravity 40 of the vibration motor 4, and the remaining one connecting portion 11b is disposed on the rear X2 side.

As shown in fig. 9, the brush attachment portion 6 is provided at the center of the three through holes 513 in a plan view. As shown in fig. 10, the brush attachment portion 6 includes: a cylindrical portion 61 formed integrally with the plate portion 511; and a shaft 62 that penetrates the cylindrical portion 61 in the vertical direction Z. As shown in fig. 6, an end portion of the cylindrical portion 61 below Z2 extends to the outside of the housing 2 through the opening 212 of the first member 21.

Further, the opening 212 is closed between the first member 21 and the cylindrical portion 61 by a seal member 213. The sealing member 213 can prevent moisture or the like from entering the hollow portion 25 through the opening 212. In this example, the sealing member 213 is made of nitrile rubber.

The shaft 62 in this example is constructed of metal. As shown in fig. 6, an end portion of the shaft 62 above Z1 extends into the hollow portion 25. Further, a screw hole 621 for electrically connecting the shaft 62 and the electric component 12 is provided on the upper end surface of the shaft 62. As shown in fig. 8 and 10, the end portion of the shaft 62 below Z2 protrudes below Z2 from the cylindrical portion 61. As shown in fig. 8, the protruding portion has: a rotation restricting portion 622 having a hexagonal prism shape; and a brush engaging portion 623 projecting downward Z2 from the rotation restricting portion 622. The brush engagement portion 623 is provided with a groove 624 for engaging the brush portion 3.

In the cosmetic device 1 of this example, when the eccentric weight 41 of the vibration motor 4 is rotated, the vibration motor 4 vibrates due to the inertia of the eccentric weight 41. Then, the motor holding portion 5 is slightly displaced and tilted in accordance with the vibration of the vibration motor 4. The direction of displacement and inclination of the motor holding portion 5 varies in various directions depending on the rotation speed of the vibration motor 4, the specific shape of the motor holding portion 5, and the like.

Further, since the motor holding portion 5 vibrates or tilts in various directions, vibration accompanied by complicated displacement in which displacements in the front-rear direction X, the width direction Y, and the vertical direction Z are combined can be applied to the bristle tips 311 of the brush main body 31.

As shown in fig. 4 and 6, in addition to the electric component 12 and the vibration motor 4, the power receiving coil unit 13 and the light emitting module 16 are housed in the hollow portion 25 between the first member 21 and the second member 22.

More specifically, the beauty device 1 of the present embodiment can be charged by the charging stand 7 shown in fig. 13 to 15. As shown in fig. 15, charging stand 7 has a concave portion 71, and this concave portion 71 corresponds to the shape of the rear end portion 17 of beauty device 1, that is, the end portion on the side where power receiving coil unit 13 is incorporated, and is configured so that rear end portion 17 of beauty device 1 can be inserted into concave portion 71. In addition, a power transmission coil 72 is housed inside the charging stand 7. The power transmission coil 72 is disposed at a position facing the power receiving coil portion 13 via the wall portion 711 of the charging stand 7 and the first member 21 (not shown) in a state where the rear end portion 17 of the cosmetic device 1 is inserted into the recess 71.

Further, the beauty device 1 of the present embodiment is configured to: when a weak current flows through the skin during use, charged dirt components and the like can be removed more efficiently. That is, as shown in fig. 3, 4, and 6, brush portion 3 in this example includes: a brush main body 31 made of a plurality of fibers; a brush holder 32 that holds the brush main body 31; and a brush electrode 325 disposed on an outer surface of the brush holder 32. The brush electrode 325 is electrically connected to the electrode portion 14 via the electric component 12.

The brush electrode 325 in this example is formed of a chromium plating film having conductivity. The brush electrode 325 is provided on the surface of the holder body 321, and is electrically connected to the shaft 62 of the brush attachment portion 6 via the brush attachment spring 323. Further, the terminal 123 (see fig. 5 and 7) of the electric wire extending from the control board 121 is fastened and coupled to a screw hole 621 provided at an end portion of the shaft 62 above Z1 by a screw. Thereby, the brush electrode 325 and the electric component 12 are electrically connected. Further, when the brush holder 32 is formed of a conductive material, the brush electrode 325 may be omitted and the brush holder 32 may also serve as a brush electrode.

The beauty device 1 of the present embodiment is configured such that: by pressing a switch (not shown) of the control board 121 through the switch plate 15 (see fig. 2 and 3) disposed at the center of the first member 21 in the upward view, the on state and the off state of the vibration motor 4 can be switched, and the generation and the stop of the weak current flowing through the skin through the brush electrode 325 and the electrode unit 14 can be switched.

As shown in fig. 6, the light emitting module 16 is disposed inside the brush accommodating wall portion 214 of the first member 21. The light emitting module 16 is configured to: the vibration motor 4 emits light when turned on.

The lower side Z2 of the light emitting module 16 is covered with a cover 161. An O-ring 162 is interposed between the lid portion 161 and the brush accommodating wall portion 214. This can prevent moisture or the like from entering the light-emitting module 16 side from between the cover 161 and the brush accommodating wall 214.

In the cosmetic device 1 of the present embodiment, the motor holding unit 5 that holds the vibration motor 4 is coupled to the casing 2 via the coupling unit 11 in a relatively displaceable state. Therefore, the relative position of the motor holding portion 5 with respect to the housing 2 can be changed relatively freely without being strongly restricted by the housing 2. Therefore, even in a state where the casing 2 is fixed, the cosmetic device 1 can efficiently transmit the vibration of the vibration motor 4 to the motor holding portion 5 and the brush attachment portion 6 extended from the motor holding portion 5.

The brush attachment portion 6 extends in a direction different from the axial direction 420 of the rotary shaft 42 of the vibration motor 4. Therefore, the vibration of the brush attachment portion 6 applied by the vibration motor 4 involves a complicated displacement in which the displacement in the axial center direction 420 (the front-rear direction X) of the rotary shaft 42 and the displacement in any direction (the width direction Y, the vertical direction Z) orthogonal to the axial center direction 420 are combined. By efficiently transmitting the vibration to the brush part 3 through the brush attachment part 6, the vibration accompanied by the complex vibration in which the displacement in the depth direction (vertical direction Z) of the sweat pores and the displacement in any direction (front-rear direction X, width direction Y) orthogonal to the depth direction (vertical direction Z) are combined can be applied to the hair tip 311 of the brush part 3. As a result, dirt and the like adhering to the surface of the skin and the inside of pores can be efficiently removed by the brush unit 3.

Further, the brush attachment portion 6 extends in a direction (vertical direction Z) perpendicular to the axial center direction 420. Therefore, the amplitude in any direction (width direction Y, vertical direction Z) orthogonal to the axial center direction 420 among the vibrations of the brush attachment portion 6 can be further increased, and the amplitude in the axial center direction 420 (front-rear direction X) can be suppressed from becoming excessively large. Therefore, the bristle tips 311 of the brush part 3 can be greatly vibrated in the depth direction of the pores. Therefore, it is possible to more efficiently remove dirt and the like adhering to the inside of pores while further reducing friction between the hair tips 311 of the brush section 3 and the skin surface.

The brush attachment portion 6 has a rotation restricting portion 622, and the rotation restricting portion 622 restricts the rotational movement of the brush portion 3 around the brush attachment portion 6 as a rotation center. Therefore, the skin can be prevented from being rubbed along with the rotational movement of the brush unit 3. As a result, the irritation to the skin during use of the cosmetic device 1 can be further reduced.

The brush portion 3 has a plurality of fibers extending in the extending direction of the brush attachment portion 6. Therefore, the vibration of the brush attachment portion 6 can be efficiently transmitted to the bristle tips of the brush portion 3. As a result, dirt and the like adhering to the surface of the skin and the inside of pores can be removed more efficiently.

Further, brush portion 3 has: a brush body 31 made of a plurality of fibers; a brush holder 32 that holds the brush main body 31; and a brush electrode 325 disposed on an outer surface of the brush holder 32. The housing 2 has: an electric component 12 housed inside; and an electrode portion 14 disposed on the outer surface. The brush electrode 325 and the electrode portion 14 are electrically connected via the electric component 12.

Therefore, the user can form a closed circuit including the user, the brush electrode 325, the electric component 12, and the electrode portion 14 by holding the electrode portion 14 and interposing a liquid, foam-like cleansing agent having conductivity between the brush electrode 325 and the skin. In addition, by flowing a weak current through the closed circuit, it is possible to perform ion cleaning and more easily remove the charged dirt components from the skin.

Here, the ion cleaning is a technique of easily removing a dirt component from the skin by making the brush electrode have an electric charge of a polarity opposite to that of the dirt component attached to the skin, thereby making the dirt component be adsorbed to the brush electrode. For example, by positively charging the brush electrode, the negatively charged dirt component can be adsorbed to the brush electrode.

As in the present embodiment, the current path between the brush electrode and the user is formed by the detergent, and the range of selection of materials that can be used as the brush can be expanded. As the brush, for example, a non-conductive material such as a synthetic resin can be used. Further, a bear pen (registered trademark) or the like may be used.

The housing 2 has a rod shape, and the vibration motor 4 and the motor holding portion 5 are accommodated in an end portion of the housing 2 in the longitudinal direction. Therefore, the user can easily hold the housing 2. This can further improve the usability of the beauty device 1.

Further, the brush portion 3 is disposed on the side peripheral surface of the housing 2. Therefore, the user can easily bring the hair tips of the brush portion 3 into contact with the skin. This can further improve the usability of the beauty device 1.

(example 2)

This example is an example of a beauty treatment device 102 configured as a beauty treatment roller. In addition, of the symbols used in the present embodiment and the following description, the same symbols as those used in the present embodiment indicate the same components and the like as those in the present embodiment unless otherwise specified.

As shown in fig. 16, the beauty device 102 of the present embodiment includes: a case 202 having a rod shape; and a pair of rotating bodies 17 rotatably held in the housing 202 via a support shaft, not shown. The housing 202 has: a grip 26 extending in one direction; and a pair of branch portions 27 extending from one end of the grip portion 26. The rotating body 17 is held at the tip of each branch 27.

The housing 202 has: a first member 21; a second member 22 engaged with the first member 21; and a third member 23 covering a part of the outer surface of the second member 22. The first member 21 and the second member 22 extend over the entire length of the grip portion 26 and the branch portion 27. The third member 23 covers a part of the outer surface of the second member 22 so that the flange portion 223 of the second member 22 is exposed to the outer surface of the case 202. The outer surface of the flange portion 223 exposed between the first member 21 and the third member 23 constitutes the electrode portion 14. The electrode portion 14 is arranged along the boundary between the first member 21 and the second member 22 in the outer surface of the case 202.

A hollow portion (not shown) is formed between the first member 21 and the second member 22. An electric component (not shown) is disposed in the hollow portion. The electric components electrically connect the electrode portion 14, the rotor electrode 171 provided on the surface of the rotor 17, and the solar cell panel 18 disposed on the grip portion 26, respectively, through a path not shown. Otherwise the same as in example 1.

The beauty treatment device 102 of this example can achieve the same operational advantages as those of embodiment 1. Further, the beauty device 102 is configured to: when a current path including the electrode portion 14, the rotator electrode 171, the electric component, and the human body is formed, a weak current called a micro current can be caused to flow through the current path. Further, by moving the beauty device 102 in the longitudinal direction of the grip portion 26 with the rotating bodies 17 in contact with the skin, the skin can be massaged by pulling up the skin with the pair of rotating bodies 17.

The aspect of the beauty device according to the present invention is not limited to the aspect of the above-described embodiment, and the configuration may be appropriately modified within the scope not impairing the gist thereof. For example, although embodiment 1 shows an example of the cosmetic device 1 having a function of removing dirt and the like on the skin by the brush unit 3 and an ion cleaning function, the cosmetic device 1 may have various functions such as iontophoresis, EMS (Electrical tissue Stimulation), ultrasonic vibration, irradiation light, heating of the skin, and cooling of the skin.

In the above embodiment, the example of the beauty appliance 1 or 102 in which the flange portion 223 is exposed over the entire periphery of the boundary between the first member 21 and the second member 22 is shown, but the flange portion 223 need not be exposed over the entire periphery of the boundary. For example, the flange portion 223 may not be provided at the end portion of the front X1 of the beauty device 1, and the flange portion 223 may be provided only at a portion located rearward of the brush accommodating wall portion 214 in the front-rear direction X, that is, a portion to be gripped by the user. In this case, a short circuit between the electrode portion 14 and the brush electrode 325 can be more easily avoided.

The position and shape of the electrode portion 14 can be changed as appropriate according to the use of the cosmetic device. For example, in the above embodiment, the electrode portion 14 is provided at the boundary between the first member 21 and the second member 22, but the surface of the second member 22 may be exposed at the center in the width direction Y of the third member 23, and the electrode portion 14 may be the portion.

The shape of the case 2, 202 is not limited to a rod shape. The case 2, 202 may be formed in a shape of, for example, a circular plate or an elliptical plate.

The second member 22 may be configured such that a coating having conductivity is provided on the surface of the material having electrical insulation as in the above-described embodiment, or may be formed of a material having conductivity, such as a pure metal or a plastic material having conductivity. Further, a chromium plating film may be provided on the surface of the conductive material to further improve the appearance.

The third member 23 may be integrally formed as in the above-described embodiment, or may be divided into a plurality of portions. For example, the third member 23 in embodiment 1 may be formed by dividing it into a front half and a rear half in the front-rear direction X.

In addition, various surface treatments may be applied to the outer surface of the third member 23 for the purpose of facilitating gripping of the case 2, improving the appearance, and the like. Further, leather or the like may be attached to the outer surface of the third member 23 for the same purpose. In this way, the third member covers a part of the outer surface of the second member 22, and thereby the operational effect of improving the degree of freedom in designing the housing 2 can be obtained.

Further, a structure in which an insulating paint is applied to a part of the outer surface of the second member, or a structure in which an insulating material is disposed on a part of the outer surface of the second member may be employed. In this case, the exposed portion of the outer surface of the second member, on which the insulating paint, the insulating material, or the like is not provided, may be used as the electrode portion. The latter structure can be realized by a known technique such as two-color molding of a conductive resin and an insulating resin, or integral molding of a conductive resin and an insulating material.

The beauty device according to the present invention is required to have a structure in which a part of the second member is covered with the third member, but in the case of the above structure, the insulating paint or the like functions as the third member, and therefore, the third member may not be provided.
