[0006] Patent Document 1: Japanese Patent No. 6282271 Summary of the Invention

[0007] According to the beauty device including electrodes disclosed in Patent Document 1, electrical stimulation that exerts a cosmetic effect on the skin can be applied. Furthermore, when using the beauty device that applies electrical stimulation, sometimes the skin is massaged while a gel or other medication is applied to enhance the effect of the electrical stimulation.

[0008] However, in traditional beauty devices, when electrical stimulation is applied simultaneously with physical massage, the medication may be rubbed off at the first or second edge. In such cases, the current from the device may not reach the skin sufficiently, potentially reducing the effectiveness of the electrical stimulation. Additionally, applying electrical stimulation to only a localized area of ​​the skin can easily cause pain due to the stimulation.

[0009] This disclosure is made in view of the problems of such prior art, and provides a beauty device that can hold a drug between itself and the skin and stably apply electrical stimulation to the skin with the help of the drug.

[0010] A beauty device disclosed herein includes: a flat body portion; and a beauty portion disposed at an end of the body portion when viewed from the thickness direction, the beauty portion being formed such that its outer periphery has at least one convex portion and at least one concave portion. The beauty device also includes an electrode portion disposed at an end of the beauty portion when viewed from the thickness direction, the electrode portion comprising a first electrode portion and a second electrode portion disposed at a position separate from the first electrode portion. Furthermore, at least one recess is provided in at least one of the following groups: the exposed surface of the first electrode portion, the area surrounding the exposed surface of the first electrode portion, the exposed surface of the second electrode portion, and the area surrounding the exposed surface of the second electrode portion.

[0011] According to this disclosure, a beauty device is available that can hold a drug between itself and the skin and stably apply electrical stimulation to the skin with the help of the drug. Attached Figure Description

Detailed Implementation

[0027] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, sometimes overly detailed descriptions are omitted. For example, detailed descriptions of already known matters or repeated descriptions of substantially the same structures may be omitted.

[0028] Furthermore, 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 of the claims.

[0029] Furthermore, in the following embodiments, the direction substantially parallel to the long side 10a of the main body 10 is designated as the length direction X or the X-direction. Additionally, the thickness direction of the main body 10 is designated as the thickness direction Z or the Z-direction. Furthermore, the direction orthogonal to both the length direction X and the thickness direction Z is designated as the width direction Y or the Y-direction.

[0030] [First Implementation]

[0031] The following uses Figures 1-6 This describes the beauty device 1 according to the first embodiment of the present disclosure. Figure 1 , Figure 2 and Figure 3 These are a perspective view, a side view, and a front view of the beauty device 1 according to the first embodiment. Figure 4 It is along Figure 3 A sectional view obtained by cutting along line IV-IV. Figure 5 This is an enlarged cross-sectional view showing the first electrode portion 31 of the beauty device 1. Figure 6 This is an enlarged cross-sectional view showing the second electrode portion 32 of the beauty device 1.

[0032] like Figures 1-4 As shown, the beauty device 1 of this embodiment includes a flat main body 10, a beauty part 20, and an electrode part 30. The beauty device 1 of this embodiment applies physical stimulation to the skin by having the user hold the main body 10, bringing the beauty part 20 into contact with the skin, and moving the beauty part 20 across the skin. Furthermore, the beauty device 1 applies electrical stimulation to the skin by energizing the electrode part 30. Thus, for example, EMS (Electrical Muscle Stimulation) training can be performed on muscles such as those in the face.

[0033] The main body 10 includes a housing 11. The housing 11 is flat and forms the outer contour of the main body 10. The main body 10 has a hollow portion 12 inside. Components including a control circuit board and a battery are housed in the hollow portion 12. The hollow portion 12 is covered from the outside by the housing 11.

[0034] When using the beauty device 1, the main body 10 functions as a handle for the user to hold. Furthermore, while holding the main body 10, the user moves the beauty part 20 against and against the user's own skin or the skin of the person being treated, thereby applying at least one of physical stimulation and electrical stimulation to the user's skin or the skin of the person being treated.

[0035] like Figure 2As shown, when viewed from the Z direction, the main body 10 is formed in a generally trapezoidal shape. The main body 10 has a long side 10a, a short side 10b, a first hypotenuse 10c, and a second hypotenuse 10d. Furthermore, the generally trapezoidal shape is formed by the long side 10a, the short side 10b, the first hypotenuse 10c, and the second hypotenuse 10d.

[0036] like Figure 2 As shown, when viewed from the Z direction, the long side 10a forms the outer periphery of the beauty device 1. The short side 10b extends along the side where the beauty part 20 is provided. The first oblique side 10c connects one end of the long side 10a to one end of the short side 10b and extends along the side where the beauty part 20 is provided. The second oblique side 10d connects the other end of the long side 10a to the other end of the short side 10b, forming the outer periphery of the beauty device 1.

[0037] The shell 11 is formed with rounded corners on its entire outer surface. This minimizes the formation of sharp edges on the outer surface. Consequently, it prevents the user's hand from touching the sharp edges and causing unnecessary stimulation when the user holds the main body 10. The shell 11 can be formed, for example, by joining multiple segments made of synthetic resin.

[0038] Viewed from the thickness direction Z of the main body 10, the cosmetic part 20 is provided at the end of the main body 10. In this embodiment, the short side 10b and the first oblique side 10c correspond to the end 10e of the main body 10, and the cosmetic part 20 is provided on the short side 10b and the first oblique side 10c of the main body 10 when viewed from the Z direction. The cosmetic part 20 is supported on the main body 10 by means of a resin support part 15.

[0039] The beauty unit 20 includes a housing 21. The housing 21 forms the outer contour of the beauty unit 20. The housing 21 forms a hollow portion internally, for example, by joining multiple segments formed with a substantially constant thickness. The housing 21 is made of metal, such as an aluminum alloy.

[0040] The beauty part 20 is formed such that its outer periphery 20a has at least one convex curved portion 22 and at least one concave curved portion 26. Specifically, the housing 21 is provided with at least one convex curved portion 22 and at least one concave curved portion 26. In this embodiment, the at least one convex curved portion 22 includes a first convex curved portion 23, a second convex curved portion 24, and a third convex curved portion 25. In addition, in this embodiment, the at least one concave curved portion 26 includes a first concave curved portion 27 and a second concave curved portion 28.

[0041] With the housing 21 located at the end 10e of the main body 10, when viewed from the Z direction, a first convex curved portion 23 is formed at the intersection 10f of the housing 21 between the long side 10a and the first oblique side 10c.

[0042] When viewed from the Z direction, the first convex portion 23 protrudes in a direction that intersects with the first inclined portion 10c (in an almost orthogonal direction). A first convex ridge portion 23d is formed on the first convex portion 23, which is smoothly continuous from the bottom 23a through the top 23b to the bottom 23c.

[0043] Furthermore, when the housing 21 is provided at the end 10e of the main body 10, when viewed from the Z direction, a second convex curved portion 24 is formed on the side of the intersection 10g between the short side portion 10b and the first oblique side portion 10c of the housing 21.

[0044] Viewed from the Z direction, the second convex portion 24 protrudes in a direction intersecting (almost orthogonal) with the first inclined portion 10c. A second convex ridge portion 24d is formed on the second convex portion 24, smoothly continuous from the bottom 24a through the top 24b to the bottom 24c. Furthermore, in this embodiment, the second convex portion 24 protrudes outward to a greater extent than the first convex portion 23.

[0045] Therefore, a first concave portion 27 is formed between the first convex portion 23 and the second convex portion 24 (between the bottom 23c and the bottom 24a) to smoothly connect the first convex portion 23 and the second convex portion 24.

[0046] Viewed from the Z direction, the first concave portion 27 is recessed in a direction intersecting (almost orthogonal) with the first inclined side portion 10c. A first concave ridge portion 27b is formed in the first concave portion 27, smoothly continuous from the bottom 23c of the first convex portion 23 through its top 27a to the bottom 24a of the second convex portion 24. Furthermore, in this embodiment, the top 27a of the first concave portion 27 refers to the portion at the bottom of the concave section of the first concave portion 27.

[0047] Furthermore, with the housing 21 positioned at the end 10e of the main body 10, when viewed from the Z direction, a third convex curved portion 25 is formed at the intersection 10h of the housing 21 between the short side 10b and the second oblique side 10d. Additionally, the intersection 10i between the long side 10a and the second oblique side 10d is formed at a position away from the cosmetic part 20.

[0048] Viewed from the Z direction, the third convex portion 25 protrudes in a direction intersecting (almost orthogonal) with the short side portion 10b. A third convex ridge portion 25d is formed on the third convex portion 25, smoothly continuous from the bottom 25a through the top 25b to the bottom 25c. Furthermore, in this embodiment, the protrusion amount of the third convex portion 25 is smaller than that of the first convex portion 23.

[0049] Therefore, in this embodiment, the protrusion amount of the second convex portion 24 (distance from the top 24b to the main body portion 10) is the largest, and the protrusion amount of the third convex portion 25 (distance from the top 25b to the main body portion 10) is the smallest. Furthermore, the protrusion amount of the first convex portion 23 (distance from the top 23b to the main body portion 10) is between the protrusion amounts of the second convex portion 24 and the third convex portion 25.

[0050] In this way, by setting three types of convex curves, a more suitable convex curve can be made to contact the skin when massaging the skin.

[0051] Furthermore, a second concave portion 28 is formed between the second convex portion 24 and the third convex portion 25 (between the bottom 24c and the bottom 25a) to smoothly connect the second convex portion 24 and the third convex portion 25.

[0052] Viewed from the Z direction, the second concave portion 28 is recessed in a direction intersecting (almost orthogonal) with the short side portion 10b. A second concave ridge portion 28b is formed in the second concave portion 28, smoothly continuous from the bottom 24c of the second convex portion 24 through its top 28a to the bottom 25a of the third convex portion 25. Furthermore, in this embodiment, the top 28a of the second concave portion 28 refers to the portion at the bottom of the concavity of the second concave portion 28.

[0053] In this embodiment, when viewed from the Z direction, the second concave portion 28 is curved more gently than the first concave portion 27. That is, the curvature of the second concave ridge portion 28b is smaller than the curvature of the first concave ridge portion 27b.

[0054] In this way, by setting two concave sections, a more suitable convex section can be made to contact the skin when massaging the skin.

[0055] Furthermore, in this embodiment, the distance between the top 24b of the second convex portion 24 and the top 25b of the third convex portion 25 is longer than the distance between the top 23b of the first convex portion 23 and the top 24b of the second convex portion 24. By forming at least one convex portion 22 in this way, a more suitable convex portion can be made to contact the skin during skin massage.

[0056] In particular, the gently curved second concave portion 28 is suitable for contact when massaging the cheeks, forehead, etc. The more curved first concave portion 27 is suitable for massaging the jaw while contacting from the cheek side to the throat side.

[0057] In addition, in this embodiment, when viewed from the Z direction, the inflection points of the curve drawn by the outer periphery 20a are set as the bottom 23c, 24a, 24c, and 25a.

[0058] Thus, in this embodiment, as Figure 2 As shown, when viewed from the Z direction, the shell 21 is shaped like an inverted lowercase letter Y.

[0059] In this embodiment, the outer periphery 20a is formed with three convex portions. However, the number of convex portions is not limited to this; one or two convex portions may be formed, or four or more convex portions may be formed.

[0060] In this embodiment, the outer periphery 20a is formed with two concave portions, including a first concave portion 27 and a second concave portion 28. However, the number of concave portions is not limited to this; one concave portion or more than three concave portions may also be formed.

[0061] Furthermore, the convex and concave portions are not limited to the applications of contacting the areas exemplified above; they can be contacted with desired areas of the body for massage. That is, the convex and concave portions can be positioned to contact desired areas of the body according to the user's or the person receiving the massage.

[0062] Viewed from the thickness direction Z, the electrode portion 30 is located at the end of the cosmetic portion 20. The electrode portion 30 is located between the top 24b of the second convex portion 24 and the top 25b of the third convex portion 25. More specifically, the electrode portion 30 is located between the top 24b of the second convex portion 24 and the bottom 25a of the third convex portion 25. Even more specifically, the electrode portion 30 is located in the second concave portion 28. The electrode portion 30 includes a first electrode portion 31 and a second electrode portion 32 located separately from the first electrode portion 31. In this embodiment, an electric current flows through the skin between the first electrode portion 31 and the second electrode portion 32, thereby enabling electrical stimulation of the skin. Compared to the top 25b of the third convex portion 25, the first electrode portion 31 and the second electrode portion 32 are positioned close to the top 24b of the second convex portion 24.

[0063] The first electrode portion 31 is disposed between the top 24b of the second convex portion 24 and the top 28a of the second concave portion 28. The first electrode portion 31 is formed from a single metal plate. From the viewpoint of improving safety, the first electrode portion 31 may also contain a metal such as titanium. Figure 5 As shown, the first electrode portion 31 includes a first exposed portion 31a, a first sidewall portion 31b, and a first fixing portion 31c.

[0064] The first exposed portion 31a is plate-shaped. It has an outer surface that contacts the skin and serves as the exposed surface, and an inner surface disposed on the side opposite to the outer surface. When viewed from a direction perpendicular to the exposed surface of the first exposed portion 31a (width direction Y), the first exposed portion 31a is oval-shaped. When viewed from the width direction Y, the first sidewall portion 31b extends from the end of the first exposed portion 31a toward the main body portion 10, forming an oval cylinder. In the width direction Y, the first fixing portion 31c extends outward parallel to the first exposed portion 31a from the end of the first sidewall portion 31b on the side opposite to the intersection point between the first exposed portion 31a and the first sidewall portion 31b. The first fixing portion 31c is fixed by being clamped between the support portion 15 and the first insulating member 35 via a spring bracket.

[0065] The second electrode portion 32 is disposed between the top 28a of the second concave portion 28 and the bottom 25a of the third convex portion 25. The second electrode portion 32 is formed from a single metal plate. From the viewpoint of improving safety, the second electrode portion 32 may also contain a metal such as titanium. Figure 6 As shown, the second electrode portion 32 includes a second exposed portion 32a, a second sidewall portion 32b, and a second fixing portion 32c.

[0066] The second exposed portion 32a is plate-shaped. It has an outer surface that contacts the skin and serves as the exposed surface, and an inner surface disposed on the side opposite to the outer surface. When viewed from a direction perpendicular to the exposed surface of the second exposed portion 32a (width direction Y), the second exposed portion 32a is oval-shaped. When viewed from the width direction Y, the second sidewall portion 32b extends from the end of the second exposed portion 32a toward the main body portion 10, forming an oval cylinder. In the width direction Y, the second fixing portion 32c extends outward parallel to the second exposed portion 32a from the end of the second sidewall portion 32b on the side opposite to the intersection point between the second exposed portion 32a and the second sidewall portion 32b. The second fixing portion 32c is fixed by being clamped between the support portion 15 and the second insulating member 36 via a spring bracket.

[0067] As an example, the beauty device 1 may also include a first elastic portion 33. The first elastic portion 33 is disposed between the first exposed portion 31a of the first electrode portion 31 and the support portion 15. The first elastic portion 33 is connected to the support portion 15. Furthermore, the first elastic portion 33 is in contact with the inner surface of the first exposed portion 31a. And, the first elastic portion 33 is electrically connected to a control circuit provided on a control circuit board. In this embodiment, the first elastic portion 33 is constructed from a conductive elastic member such as a coil. The first exposed portion 31a and the first elastic portion 33 are firmly in contact by the elastic force of the elastic member, thus stabilizing the electrical connection between the first exposed portion 31a and the control circuit.

[0068] As an example, the beauty device 1 may also include a second elastic portion 34. The second elastic portion 34 is disposed between the second exposed portion 32a of the second electrode portion 32 and the support portion 15. The second elastic portion 34 is connected to the support portion 15. Furthermore, the second elastic portion 34 is in contact with the inner surface of the second exposed portion 32a. And, the second elastic portion 34 is electrically connected to a control circuit provided on a control circuit board. In this embodiment, the second elastic portion 34 is constructed from a conductive elastic member such as a coil. The second exposed portion 32a and the second elastic portion 34 are firmly in contact by the elastic force of the elastic member, thus stabilizing the electrical connection between the second exposed portion 32a and the control circuit.

[0069] A first recess 31d is provided on the exposed surface of the first electrode portion 31. When viewed from a direction perpendicular to the exposed surface of the first electrode portion 31, the depth of the first recess 31d is formed to increase as it moves inward from the outer periphery of the exposed surface of the first electrode portion 31. When viewed from the thickness direction Z, the first recess 31d is recessed inward from the end of the cosmetic portion 20.

[0070] A second recess 32d is provided on the exposed surface of the second electrode portion 32. When viewed from a direction perpendicular to the exposed surface of the second electrode portion 32, the depth of the second recess 32d is formed to increase as it moves inward from the outer periphery of the exposed surface of the second electrode portion 32. When viewed from the thickness direction Z, the second recess 32d is recessed inward from the end of the cosmetic portion 20.

[0071] The first recess 31d and the second recess 32d can hold the gel or other medication. Therefore, when the electrode portion 30 comes into contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin. Therefore, the beauty device 1 according to this embodiment can perform beauty treatments while simultaneously applying the effects of massage and electrical stimulation.

[0072] As an example, the agent could also be a gel containing water and a moisturizer. By placing the gel between the skin and the electrode, an electric current can flow effectively from the electrode portion 30 to the skin via the moisture in the gel. Glycerin can be cited as an example of a moisturizer.

[0073] A first insulating member 35 is provided between the housing 21 and the first electrode portion 31. A second insulating member 36 is provided between the housing 21 and the second electrode portion 32. The first insulating member 35 surrounds the first electrode portion 31, and the second insulating member 36 surrounds the second electrode portion 32. When viewed from the Y direction, the first insulating member 35 and the second insulating member 36 are oval in shape. The first insulating member 35 and the second insulating member 36 are made of an insulating material such as resin or elastomer.

[0074] When viewed from the width direction Y, the first electrode portion 31 and the second electrode portion 32 are separated by the first insulating member 35 and the second insulating member 36. As a result, the flow of current from the first electrode portion 31 and the second electrode portion 32 to the metal housing 21 can be suppressed by the first insulating member 35 and the second insulating member 36.

[0075] A recess 37 is provided around the first electrode portion 31. The recess 37 is formed by the first insulating member 35 and the housing 21. Specifically, the outer surface of the housing 21 that forms the bottom of the recess 37 is lower than the top of the outer surface of the first insulating member 35, thus forming the recess 37. The depth R1 of the recess 37 is, for example, 0.4 mm. Additionally, a recess 38 is provided around the second electrode portion 32. The recess 38 is formed by the second insulating member 36 and the housing 21. Specifically, the outer surface of the housing 21 that forms the bottom of the recess 38 is lower than the top of the outer surface of the second insulating member 36, thus forming the recess 38. The depth R2 of the recess 38 is, for example, 0.4 mm. The recesses 37 and 38 can form a liquid storage portion for holding a drug such as a gel. The medication held in the recesses 37 and 38 is supplied evenly to the electrode portion 30 during use, so that the stimulation is not uneven when the electrode portion 30 comes into contact with the skin, and electrical stimulation can be stably applied to the skin.

[0076] As an example, such as Figures 4-6 As shown, the beauty device 1 may also include a heating part 40 for heating at least a portion of the beauty part 20. By providing the heating part 40 to the beauty part 20, the beauty part 20, which is in contact with the user's skin, can be heated by the heating part 40 to provide a warm sensation to the skin. The heating part 40 is located inside the housing 21. Specifically, the heating part 40 is located between the housing 21 and the support part 15. As an example, the heating part 40 may also be provided on the support part 15 with the heating surface of the heating part 40 facing the inner surface of the housing 21.

[0077] The heating element 40 is generally a thin plate, and is expected to be flexibly deformable in accordance with the shape of the portion on which the heating element 40 is disposed. There are no particular limitations on the structure that can be adopted for the heating element 40; for example, it could be a plate heater with a built-in sleeve-type heater. The heating element 40 is electrically connected to a control circuit provided on a control circuit board.

[0078] The heating element 40 is disposed inside at least one convex portion 22. For example, the heating element 40 is preferably disposed inside a second convex portion 24, which is envisioned as the part that the user will most often bring into contact with the skin. In this case, the heating element 40 extends at least from the vicinity of the bottom 24a through the top 24b to the vicinity of the bottom 24c.

[0079] In addition, Figure 4In the example shown, the heating element 40 is not only disposed inside the second convex portion 24, but also continuously disposed from the second convex portion 24 to the third convex portion 25. In this case, the area of ​​the beauty part 20 heated by the heating element 40 extends not only around the second convex portion 24, but also around the third convex portion 25.

[0080] Alternatively, the heating unit 40 can heat not only the housing 21 but also the electrode unit 30. In this case, it is possible to simultaneously provide a warm sensation to the skin using the heating unit 40 and apply electrical stimulation to the skin using the electrode unit 30.

[0081] In this embodiment, a first recess 31d is provided on the exposed surface of the first electrode portion 31, and a second recess 32d is provided on the exposed surface of the second electrode portion 32. Additionally, a recess 37 is provided around the first electrode portion 31, and a recess 38 is provided around the second electrode portion 32. However, at least one recess may be provided from at least one of the group consisting of the exposed surface of the first electrode portion 31, the area surrounding the exposed surface of the first electrode portion 31, the exposed surface of the second electrode portion 32, and the area surrounding the exposed surface of the second electrode portion 32.

[0082] In this embodiment, the first electrode portion 31 is fixed by the first fixing portion 31c, but the first elastic portion 33 can also support the first electrode portion 31 such that the exposed surface of the first electrode portion 31 swings in a direction perpendicular to the exposed surface of the first electrode portion 31. Thus, when the beauty device 1 is brought into contact with the skin, the first electrode portion 31 is pressed in by the skin, forming a recess with the exposed surface of the first electrode portion 31 as its bottom surface. The medication is retained in the recess, thus enabling stable application of electrical stimulation to the skin.

[0083] In this embodiment, the second electrode portion 32 is fixed by the second fixing portion 32c, but the second elastic portion 34 can also support the second electrode portion 32 such that the exposed surface of the second electrode portion 32 swings in a direction perpendicular to the exposed surface of the second electrode portion 32. Thus, when the beauty device 1 is brought into contact with the skin, the second electrode portion 32 is pressed in by the skin, forming a recess with the exposed surface of the second electrode portion 32 as its bottom surface. The medication is retained in the recess, thus enabling stable application of electrical stimulation to the skin.

[0084] [Second Implementation]

[0085] Next, use Figure 7 and Figure 8 This describes the beauty device 1 of the second embodiment. Figure 7 This is a cross-sectional view showing the first electrode portion 31 of the beauty device 1 according to this embodiment. Figure 8This is a cross-sectional view showing the second electrode portion 32 of the beauty device 1 according to this embodiment. The shape of the electrode portion 30 of the beauty device 1 in this embodiment differs from that in the beauty device 1 of the first embodiment. Otherwise, it is the same as the beauty device 1 of the first embodiment, therefore, the description is omitted.

[0086] Specifically, in the beauty device 1 of the first embodiment, the depth of the first recess 31d is formed such that it increases from the outer periphery of the exposed surface of the first electrode portion 31 toward the inward side. Similarly, the depth of the second recess 32d is formed such that it increases from the outer periphery of the exposed surface of the second electrode portion 32 toward the inward side.

[0087] On the other hand, in the beauty device 1 of this embodiment, such as Figure 7 As shown, multiple third recesses 31e are provided on the exposed surface of the first electrode portion 31. Additionally, as... Figure 8 As shown, a plurality of fourth recesses 32e are provided on the exposed surface of the second electrode portion 32.

[0088] As in this embodiment, by providing multiple recesses on the exposed surfaces of the first electrode portion 31 and the second electrode portion 32, the medication is retained in the multiple recesses. Therefore, the medication can be retained between the medication and the skin, and electrical stimulation can be stably applied to the skin by means of the medication.

[0089] The depth and opening diameter of each of the plurality of third recesses 31e, and the depth and opening diameter of each of the plurality of fourth recesses 32e, are not particularly limited. The diameter of the opening of each of the plurality of third recesses 31e may also be smaller than the diameter of the minor axis of the exposed surface of the first electrode portion 31. Similarly, the diameter of the opening of each of the plurality of fourth recesses 32e may also be smaller than the diameter of the minor axis of the exposed surface of the second electrode portion 32. In addition, the minor axis referred to here is the shortest line segment among the line segments that pass through the center of the first electrode portion 31 or the second electrode portion 32 and connect the ends of the exposed surfaces of the first electrode portion 31 or the second electrode portion 32. Furthermore, the number of third recesses 31e provided in the first electrode portion 31 and the number of fourth recesses 32e provided in the second electrode portion 32 are not particularly limited.

[0090] Furthermore, the plurality of third recesses 31e may be provided on at least a portion of the exposed surface of the first exposed portion 31a. Specifically, the plurality of third recesses 31e may be provided on the entire exposed surface of the first exposed portion 31a, or on a portion of the first exposed portion 31a, such as the center portion. Similarly, the plurality of fourth recesses 32e may be provided on at least a portion of the exposed surface of the second electrode portion 32. Specifically, the plurality of fourth recesses 32e may be provided on the entire exposed surface of the second electrode portion 32, or on a portion of the second electrode portion 32, such as the center portion.

[0091] In addition, Figure 7 and Figure 8 In this embodiment, the first exposed portion 31a of the first electrode portion 31 and the second exposed portion 32a of the second electrode portion 32 do not curve smoothly as in the first embodiment. However, it is also possible to provide a plurality of third recesses 31e on the exposed surface of the first electrode portion 31, and to form the first recesses 31d such that their depth increases from the outer periphery of the exposed surface of the first electrode portion 31 toward the inward side. Similarly, it is also possible to provide a plurality of fourth recesses 32e on the exposed surface of the second electrode portion 32, and to form the second recesses 32d such that their depth increases from the outer periphery of the exposed surface of the second electrode portion 32 toward the inward side.

[0092] Furthermore, in this embodiment, a third recess 31e is provided as a plurality of recesses on the exposed surface of the first electrode portion 31, and a fourth recess 32e is provided as a plurality of recesses on the exposed surface of the second electrode portion 32. However, the plurality of recesses may be provided on at least one of the exposed surfaces of the first electrode portion 31 and the second electrode portion 32.

[0093] [Third Implementation]

[0094] Next, use Figure 9 and Figure 10 This describes the beauty device 1 of the third embodiment. Figure 9 This is a cross-sectional view showing the first electrode portion 31 of the beauty device 1 according to this embodiment. Figure 10 This is a cross-sectional view showing the second electrode portion 32 of the beauty device 1 according to this embodiment. The shapes of the first insulating member 35 and the second insulating member 36 of the beauty device 1 according to this embodiment are different from those of the beauty device 1 of the first embodiment. Otherwise, it is the same as the beauty device 1 of the first embodiment, and therefore description is omitted.

[0095] Specifically, in the first embodiment, the first insulating member 35 is disposed in the housing 21 such that the edge of the exposed surface of the first electrode portion 31 is at the same height as the outer surface of the first insulating member 35. Furthermore, in the first embodiment, the second insulating member 36 is disposed in the housing 21 such that the edge of the exposed surface of the second electrode portion 32 is at the same height as the outer surface of the second insulating member 36.

[0096] On the other hand, in the beauty device 1 of this embodiment, such as Figure 9 As shown, a first protrusion 35a is provided around the exposed surface of the first electrode portion 31, protruding outward in a direction perpendicular to the exposed surface of the first electrode portion 31. Additionally, as... Figure 10As shown, a second protrusion 36a is provided around the exposed surface of the second electrode portion 32, protruding outward in a direction perpendicular to the exposed surface of the second electrode portion 32. In this embodiment, the first protrusion 35a is formed by the first insulating member 35. The second protrusion 36a is formed by the second insulating member 36.

[0097] By providing the first protrusion 35a, a first recess 31d is formed on the exposed surface of the first electrode portion 31 by an amount that increases in depth beyond the protrusion of the first protrusion 35a. Furthermore, by providing the second protrusion 36a, a second recess 32d is formed on the exposed surface of the second electrode portion 32 by an amount that increases in depth beyond the protrusion of the second protrusion 36a.

[0098] In addition, as an example, such as Figure 9 As shown, the first protrusion 35a may also protrude outward from the outer periphery of the housing 21 in a direction perpendicular to the outer periphery of the housing 21. Furthermore, as an example, such as... Figure 10 As shown, the second protrusion 36a may also protrude outward from the outer periphery of the housing 21 in a direction perpendicular to the outer periphery of the housing 21.

[0099] By providing the first protrusion 35a, a recess 37 with a depth increased by the amount protruding from the first protrusion 35a is provided around the first electrode portion 31. Furthermore, by providing the second protrusion 36a, a recess 38 with a depth increased by the amount protruding from the second protrusion 36a is provided around the second electrode portion 32.

[0100] Therefore, the medication is held in these recesses, thus allowing the medication to remain between the medication and the skin, and enabling the stable application of electrical stimulation to the skin with the help of the medication.

[0101] Figure 11 This is the front view of the beauty device 1 of this embodiment. Figure 12 It is along Figure 11 A sectional view obtained by cutting along line XII-XII. Figure 13 It is along Figure 11 A sectional view obtained by cutting along line XIII-XIII. For example... Figure 11 and Figure 12 As shown, it is also possible that, when viewed from a direction perpendicular to the exposed surface of the first electrode portion 31, a notch 35b is provided in a portion of the first protrusion 35a. Additionally, as... Figure 11 and Figure 13As shown, alternatively, when viewed from a direction perpendicular to the exposed surface of the second electrode portion 32, a notch 36b may be provided in a portion of the second protrusion 36a. Thus, when massaging the skin with a gel or other medication applied, the medication passes through the notch 35b and the notch 36b and moves towards the exposed surfaces of the first electrode portion 31 and the second electrode portion 32, respectively. Furthermore, the medication on the exposed surfaces is blocked by the first protrusion 35a and the second protrusion 36a, thereby preventing leakage to the outside of the first insulating member 35 and the second insulating member 36. Therefore, the medication can be stably held in these recesses.

[0102] As an example, the notch 35b may also be provided at the end of the first insulating member 35 in the thickness direction Z. Similarly, as an example, the notch 36b may also be provided at the end of the second insulating member 36 in the thickness direction Z. Since the beauty device 1 often moves in the thickness direction Z while in contact with the skin, providing the notch 35b and notch 36b at the positions described above facilitates the retention of the medication on the electrode portion 30.

[0103] The position of the notch 35b relative to the first electrode 31 and the position of the notch 36b relative to the second electrode 32 can be the same or different. When their positions are the same, it is preferable that the notch 35b and notch 36b can easily retain the medication on the exposed surfaces of the first electrode 31 and the second electrode 32 while the beauty device 1 is moving in contact with the skin.

[0104] Furthermore, in this embodiment, an example is described with both a first protrusion 35a and a second protrusion 36a, but at least one of the first protrusion 35a and the second protrusion 36a may also be provided.

[0105] Furthermore, in this embodiment, an example is described where a notch 35b is provided in both the first protrusion 35a and the second protrusion 36a. However, the notch may be provided in at least one of the first protrusion 35a and the second protrusion 36a.

[0106] As described above, the beauty device 1 of the above embodiment includes a flat body portion 10, a beauty portion 20, and an electrode portion 30. The beauty portion 20, viewed from the thickness direction Z of the body portion 10, is located at the end of the body portion 10. The beauty portion 20 is formed such that its outer periphery 20a has at least one convex curved portion 22 and at least one concave curved portion 26. The electrode portion 30, viewed from the thickness direction Z, is located at the end of the beauty portion 20. The electrode portion 30 includes a first electrode portion 31 and a second electrode portion 32 located separately from the first electrode portion 31. At least one concave portion is provided in at least one of the following groups: the exposed surface of the first electrode portion 31, the area surrounding the exposed surface of the first electrode portion 31, the exposed surface of the second electrode portion 32, and the area surrounding the exposed surface of the second electrode portion 32.

[0107] Therefore, the gel or other medication can be retained in the recessed area, and the stimulation is not uneven when the electrode portion 30 is in contact with the skin, allowing for stable application of electrical stimulation to the skin. Thus, the beauty device 1 according to the embodiments of this disclosure can perform beauty treatments while simultaneously applying the effects of massage and electrical stimulation.

[0108] Alternatively, as disclosed herein, at least one recess may include a first recess 31d provided on the exposed surface of the first electrode portion 31 and a second recess 32d provided on the exposed surface of the second electrode portion 32. Alternatively, the depth of the first recess 31d may be formed to increase from the outer periphery of the exposed surface of the first electrode portion 31 toward the inward side. Alternatively, the depth of the second recess 32d may be formed to increase from the outer periphery of the exposed surface of the second electrode portion 32 toward the inward side.

[0109] Therefore, the medication can be retained in the first recess 31d and the second recess 32d. Thus, when the electrode portion 30 is in contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin.

[0110] Alternatively, as disclosed herein, at least one recess may include a plurality of third recesses 31e provided on the exposed surface of the first electrode portion 31 and a plurality of fourth recesses 32e provided on the exposed surface of the second electrode portion 32.

[0111] Therefore, the medication can be retained in the third recess 31e and the fourth recess 32e. Thus, when the electrode portion 30 is in contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin.

[0112] Alternatively, as disclosed herein, a first protrusion 35a may be provided around the first electrode portion 31, protruding outward in a direction perpendicular to the exposed surface of the first electrode portion 31. Alternatively, a second protrusion 36a may be provided around the second electrode portion 32, protruding outward in a direction perpendicular to the exposed surface of the second electrode portion 32.

[0113] Therefore, recesses can be formed on the exposed surfaces of the first electrode portion 31 and the second electrode portion 32, and the medication can be retained in the recesses. Thus, when the electrode portion 30 is in contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin.

[0114] Alternatively, as disclosed herein, a notch 35b may be provided in a portion of the first protrusion 35a when viewed from a direction perpendicular to the exposed surface of the first electrode portion 31. Similarly, a notch 36b may be provided in a portion of the second protrusion 36a when viewed from a direction perpendicular to the exposed surface of the second electrode portion 32.

[0115] Therefore, when massaging the skin with a gel or other medication applied, the medication passes through the notches 35b and 36b and moves towards the exposed surfaces of the first electrode 31 and the second electrode 32. Furthermore, the medication on the exposed surfaces is blocked by the first protrusion 35a and the second protrusion 36a, thereby preventing leakage to the outside of the first insulating member 35 and the second insulating member 36. Therefore, recesses can be formed on the exposed surfaces of the first electrode 31 and the second electrode 32, retaining the medication within these recesses. Thus, when the electrode 30 contacts the skin, the stimulation is not uneven, and stable electrical stimulation can be applied to the skin.

[0116] Alternatively, as disclosed herein, the beauty device 1 may also include a heating section 40 for heating at least a portion of the beauty section 20. Alternatively, the beauty section 20 may include a housing 21 having at least one convex portion 22 and at least one concave portion 26 and containing metal. Alternatively, the first convex portion 35a and the second convex portion 36a may contain insulating material.

[0117] Therefore, the beauty part 20, which comes into contact with the user's skin, can be heated by the heating part 40 to provide a warm sensation to the skin. Furthermore, since the first protrusion 35a and the second protrusion 36a are formed of insulating members, short circuits between the beauty part 20 and the electrode part 30 can be suppressed, and the medication can be retained in the recess. Thus, the first protrusion 35a and the second protrusion 36a serve both to retain the medication and to suppress short circuits, thereby enabling the beauty device 1 to be made more compact.

[0118] Alternatively, as disclosed herein, the beauty device 1 may also include a first elastic portion 33 and a second elastic portion 34. Alternatively, the first elastic portion 33 may support the first electrode portion 31 such that the exposed surface of the first electrode portion 31 swings in a direction perpendicular to the exposed surface of the first electrode portion 31. Alternatively, the second elastic portion 34 may support the second electrode portion 32 such that the exposed surface of the second electrode portion 32 swings in a direction perpendicular to the exposed surface of the second electrode portion 32.

[0119] Thus, by pressing the first electrode portion 31 and the second electrode portion 32, recesses can be formed on their exposed surfaces, and the medication can be retained in the recesses. Therefore, when the electrode portion 30 is in contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin.

[0120] Alternatively, as disclosed herein, at least one convex portion 22 may include a first convex portion 23, a second convex portion 24, and a third convex portion 25. Alternatively, the electrode portion 30 may be disposed between the top 24b of the second convex portion 24 and the top 25b of the third convex portion 25. Alternatively, the distance between the top 24b of the second convex portion 24 and the top 25b of the third convex portion 25 may be longer than the distance between the top 23b of the first convex portion 23 and the top 24b of the second convex portion 24.

[0121] Therefore, it is possible to apply electrical stimulation while performing a physical massage on the jaw, with the jaw pressed against the cheek and throat.

[0122] Alternatively, as disclosed herein, the first electrode portion 31 and the second electrode portion 32 may be positioned closer to the top 24b of the second convex portion 24 than the top 25b of the third convex portion 25.

[0123] This allows the electrode 30 to easily come into contact with the target area to be electrically stimulated along the facial contours. Therefore, even for users with small faces, it is possible to appropriately apply electrical stimulation to the facial muscles. Thus, effective EMS training of the facial muscles is possible.

[0124] Alternatively, the beauty device 1 can be described as follows: a flat main body 10 that massages the skin with its edge; an electrical stimulation part that applies electrical stimulation; and a recess that holds a conductive agent in or near the electrical stimulation part. With such a beauty device 1, the agent can be held in the recess, ensuring that the stimulation is not uneven when the electrode part 30 is in contact with the skin, and enabling stable application of electrical stimulation to the skin.

[0125] Alternatively, the electrical stimulation part may have one or more electrode parts 30. This allows for the application of electrical stimulation to the skin.

[0126] Alternatively, the electrode portion 30 may have rounded corners on its electrode surface. Such an electrode portion 30 can also retain the drug on the electrode surface.

[0127] Alternatively, the electrode portion 30 may have an uneven shape on its electrode surface. Such an electrode portion 30 can also retain the drug on the electrode surface.

[0128] Alternatively, a protrusion may be provided around the electrode portion 30. With such a protrusion, the medication can be retained in the vicinity of the protrusion.

[0129] Alternatively, the protrusions may be located only on a localized area around the electrode portion 30, for example, on three of the four sides. In this configuration, as described above, the medication moves towards the electrode surface from the portion where the protrusions are not located, as the medication is blocked by the protrusions. Therefore, when the electrode portion 30 contacts the skin, the stimulation is not uneven, and stable electrical stimulation can be applied to the skin.

[0130] Alternatively, the beauty device 1 may include a heating part that provides a warming sensation to the skin when massaging it with the main body 10. This allows it to provide a warming sensation to the skin.

[0131] Alternatively, the edge of the flat, skin-massaging main body 10 can be made of metal to conduct heat from the heating part 40, while the protrusions around the electrode part 30 can be made of an insulating material. Thus, the metal in contact with the user's skin can be heated by the heating part 40, providing a warm sensation. Furthermore, the protrusions are made of an insulating material, which helps prevent short circuits between the metal and the electrode part 30, and allows the medication to be retained in the recesses. In this way, the protrusions serve both to retain the medication and to prevent short circuits, allowing for a more compact beauty device 1.

[0132] Alternatively, the electrode portion 30 can be supported by an elastic member. This allows a recess to be formed on the electrode surface by pressing the electrode portion 30, holding the medication within the recess. Therefore, when the electrode portion 30 is in contact with the skin, the stimulation is not uneven, and electrical stimulation can be stably applied to the skin.

[0133] Alternatively, the beauty device 1 may include a vibrating part that applies vibration to the skin when the main body 10 is used to massage the skin. This allows the beauty device 1 to vibrate mechanically, thus providing physical stimulation to the skin even when the beauty part 20 is in contact with the skin, without the user directly moving the beauty device 1.

[0134] Alternatively, the beauty device 1 may include an electrical stimulation control unit that controls the degree of electrical stimulation by determining the retention status of the conductive agent in a recess. This allows the degree of electrical stimulation to be adjusted based on the retention status of the agent, thus enabling the application of electrical stimulation most suitable for the user to the skin.

[0135] Furthermore, the above-described embodiments are used to illustrate the technology disclosed herein, and therefore various modifications, substitutions, additions, omissions, etc., can be made within the scope of the claims or their equivalents.

[0136] For example, in the above embodiment, an example was described where the first insulating member 35 protrudes above the same plane relative to the exposed surface of the first electrode portion 31. However, it is also possible that at least one recess includes a recess formed by making the top end of the outer surface of the first insulating member 35 recessed below the exposed surface of the first electrode portion 31. Similarly, an example was described where the second insulating member 36 protrudes above the same plane relative to the exposed surface of the second electrode portion 32. However, it is also possible that at least one recess includes a recess formed by making the top end of the outer surface of the second insulating member 36 recessed below the exposed surface of the second electrode portion 32. Thus, at least one of the first insulating member 35 and the second insulating member 36 forms the bottom of the recess. Therefore, it is possible to retain a drug such as a gel in this recess.

[0137] Furthermore, in the above embodiment, an example was described where the electrode portion 30 includes two electrode portions, a first electrode portion 31 and a second electrode portion 32. However, the electrode portion 30 may also include three or more electrode portions. Specifically, the electrode portion 30 may also include a third electrode portion located separately from the first electrode portion 31 and the second electrode portion 32. Alternatively, the third electrode portion may be positioned closer to the top 25b of the third convex portion 25 than the top 24b of the second convex portion 24. As a result, the distance between the first electrode portion 31 and the third electrode portion is longer than the distance between the first electrode portion 31 and the second electrode portion 32. Therefore, by flowing current between the first electrode portion 31 and the third electrode portion, electrical stimulation can be applied to larger muscles, such as the thigh muscles.

[0138] In addition, the specifications (shape, size, layout, etc.) of the shell and other details can also be changed appropriately.

[0139] Industrial availability

[0140] As described above, the beauty device disclosed herein can retain the medication between itself and the skin and stably apply electrical stimulation to the skin using the medication. Specifically, the beauty device can be used in commercial and home-use applications.
