DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.
[0012] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.
[0013] In the following embodiments, a direction substantially parallel to the long side 10a of the main body 10 is referred to as a longitudinal direction X or X direction. A thickness direction of the main body 10 is referred to as a thickness direction Z or Z direction. A direction perpendicular to the longitudinal direction X and perpendicular to the thickness direction Z is referred to as a transverse direction Y or Y direction.
[0014] [First embodiment] Hereinafter, a beauty tool 1 according to this embodiment will be described with reference to Figs.
[0015] As shown in Figs. 1 to 4, the beauty tool 1 according to this embodiment includes a flat main body 10, a treatment unit 20, and an electrode unit 30. The beauty tool 1 according to this embodiment applies a physical stimulus to the skin when the user holds the main body 10, brings the treatment unit 20 into contact with the skin, and moves the treatment unit 20 on the skin. The beauty tool 1 applies an electrical stimulus to the skin by energizing the electrode unit 30. This allows EMS (Electrical Muscle Stimulation) training of muscles such as the face.
[0016] The main body 10 includes a housing 11. The housing 11 is flat and forms the outer shell of the main body 10. The main body 10 has a hollow portion 12 therein. Electrical products such as a control circuit board and a storage battery are housed in the hollow portion 12. The hollow portion 12 is covered by the housing 11 from the outside.
[0017] The main body 10 functions as a gripping part that is held by the user in the hand when using the beauty tool 1. Then, while the user is holding the main body 10, the treatment part 20 is brought into contact with the user's own skin or the skin of a person to be treated other than the user and moved, whereby at least one of a physical stimulus and an electrical stimulus is applied to the skin of the user or the person to be treated.
[0018] 2, the main body 10 is formed to have a substantially trapezoidal shape when viewed from the Z direction. The main body 10 has a long side portion 10a, a short side portion 10b, a first oblique side portion 10c, and a second oblique side portion 10d. The substantially trapezoidal shape is formed by the long side portion 10a, the short side portion 10b, the first oblique side portion 10c, and the second oblique side portion 10d.
[0019] As shown in Fig. 2, the long side portion 10a forms the outer periphery of the beauty tool 1 when viewed from the Z direction. The short side portion 10b extends to the side where the treatment unit 20 is provided. The first oblique side portion 10c connects one end of the long side portion 10a to one end of the short side portion 10b, and extends to the side where the treatment unit 20 is provided. The second oblique side portion 10d connects the other end of the long side portion 10a to the other end of the short side portion 10b, and forms the outer periphery of the beauty tool 1.
[0020] The housing 11 is formed so that the outer surface is generally rounded. This can minimize the formation of edges on the outer surface. When a user holds the main body 10, the edges can be prevented from hitting the user's hand, which can prevent unnecessary irritation to the user's hand. The housing 11 may be formed by joining together a plurality of divided bodies made of, for example, synthetic resin.
[0021] The treatment unit 20 is provided at an end of the main body 10 when viewed from the thickness direction Z of the main body 10. In this embodiment, the short side portion 10b and the first oblique side portion 10c correspond to the end portion 10e of the main body 10, and the treatment unit 20 is provided at the short side portion 10b and the first oblique side portion 10c of the main body 10 when viewed from the Z direction. The treatment unit 20 is supported by the main body 10 via a support portion 15 made of resin.
[0022] The treatment unit 20 includes a housing 21. The housing 21 forms the outer shell of the treatment unit 20. The housing 21 has a hollow portion formed therein, for example, by joining together a plurality of divided bodies formed with an approximately uniform thickness. The housing 21 is made of metal, and includes a metal such as an aluminum alloy.
[0023] The treatment portion 20 is formed such that the outer peripheral edge 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.
[0024] When the housing 21 is attached to the end portion 10e of the main body 10 and viewed from the Z direction, a first convex portion 23 is formed on the housing 21 on the side of the intersection 10f between the long side portion 10a and the first oblique side portion 10c.
[0025] The first convex curved portion 23 protrudes in a direction intersecting (substantially perpendicular to) the first oblique side portion 10c when viewed from the Z direction. The first convex curved portion 23 has a first convex ridge portion 23d that smoothly continues from the bottom portion 23a through the apex portion 23b to the bottom portion 23c.
[0026] In addition, when the housing 21 is attached to the end portion 10e of the main body 10 and viewed from the Z direction, a second convex 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.
[0027] The second convex curved portion 24 protrudes in a direction intersecting (almost perpendicular to) the first oblique side portion 10c when viewed from the Z direction. The second convex curved portion 24 has a second convex ridge portion 24d that smoothly continues from the bottom portion 24a through the apex portion 24b to the bottom portion 24c. In this embodiment, the second convex curved portion 24 protrudes farther outward than the first convex curved portion 23.
[0028] Furthermore, a first concave curved portion 27 that smoothly connects first convex curved portion 23 and second convex curved portion 24 is formed between first convex curved portion 23 and second convex curved portion 24 (between bottom portion 23c and bottom portion 24a).
[0029] The first concave curved portion 27 is recessed in a direction intersecting (almost perpendicular to) the first oblique side portion 10c when viewed from the Z direction. The first concave curved portion 27 has a first concave ridge portion 27b that smoothly continues from the bottom 23c of the first convex curved portion 23 through the apex 27a to the bottom 24a of the second convex curved portion 24.
[0030] When the housing 21 is provided on the end portion 10e of the main body 10 and viewed from the Z direction, a third convex portion 25 is formed on the side of an intersection 10h between the short side portion 10b and the second oblique side portion 10d of the housing 21. The intersection 10i between the long side portion 10a and the second oblique side portion 10d is formed at a position away from the treatment area 20.
[0031] The third convex curved portion 25 protrudes in a direction intersecting (almost perpendicular to) the short side portion 10b when viewed from the Z direction. The third convex curved portion 25 has a third convex ridge portion 25d that smoothly continues from the bottom portion 25a through the apex portion 25b to the bottom portion 25c. In this embodiment, the third convex curved portion 25 protrudes less than the first convex curved portion 23.
[0032] Therefore, in this embodiment, the protrusion amount of the second convex curved portion 24 (the distance from the apex 24b to the main body 10) is the largest, and the protrusion amount of the third convex curved portion 25 (the distance from the apex 25b to the main body 10) is the smallest. The protrusion amount of the first convex curved portion 23 (the distance from the apex 23b to the main body 10) is intermediate between the protrusion amount of the second convex curved portion 24 and the protrusion amount of the third convex curved portion 25.
[0033] In this way, by providing three types of convex curved portions, a more optimal convex curved portion can be brought into contact with the skin when massaging the skin.
[0034] Between the second convex curved portion 24 and the third convex curved portion 25 (between the bottom portion 24c and the bottom portion 25a), a second concave curved portion 28 that smoothly connects the second convex curved portion 24 and the third convex curved portion 25 is formed.
[0035] The second concave curved portion 28 is recessed in a direction intersecting (almost perpendicular to) the short side portion 10b when viewed from the Z direction. The second concave curved portion 28 has a second concave ridge portion 28b that smoothly continues from the bottom 24c of the second convex curved portion 24 through the apex 28a to the bottom 25a of the third convex curved portion 25.
[0036] In this embodiment, when viewed from the Z direction, the second concave curved portion 28 is curved more gently than the first concave curved portion 27. That is, the second concave ridge portion 28b has a smaller curvature than the first concave ridge portion 27b.
[0037] In this way, by providing two types of concave curved portions, a more optimal convex curved portion can be brought into contact with the skin when massaging the skin.
[0038] Furthermore, in this embodiment, the distance between the apex 24b of the second convex curved portion 24 and the apex 25b of the third convex curved portion 25 is longer than the distance between the apex 23b of the first convex curved portion 23 and the apex 24b of the second convex curved portion 24. By forming at least one convex curved portion 22 in this manner, it is possible to bring a more optimal convex curved portion into contact with the skin when massaging the skin.
[0039] In particular, the gently curved second concave curved portion 28 is suitable for contact when massaging the cheeks, forehead, etc. The largely curved first concave curved portion 27 is suitable for massaging the jaw while being in contact from the cheek side to the throat side.
[0040] In this embodiment, when viewed from the Z direction, the inflection points of the curved line of the outer circumferential edge 20a are the bottoms 23c, 24a, 24c, and 25a.
[0041] Thus, in this embodiment, the housing 21 is formed so as to have a shape similar to a lowercase inverted y when viewed from the Z direction, as shown in FIG.
[0042] In this embodiment, the outer peripheral edge 20a is formed to have three convex curved portions. However, the number of convex curved portions is not limited to this, and one or two convex curved portions may be formed, or four or more convex curved portions may be formed.
[0043] In this embodiment, the outer circumferential edge 20a is formed to have two concave curved portions including the first concave curved portion 27 and the second concave curved portion 28. However, the number of concave curved portions is not limited to this, and one concave curved portion may be formed, or three or more concave curved portions may be formed.
[0044] The convex and concave curved portions are not limited to the above-mentioned applications, but can be brought into contact with any desired part of the human body for massage. In other words, the convex and concave curved portions can be brought into contact with any desired part of the human body according to the preference of the user or person receiving massage.
[0045] The electrode portion 30 is provided at the end of the treatment portion 20 when viewed from the thickness direction Z. The electrode portion 30 is provided between the apex 24b of the second convex curved portion 24 and the apex 25b of the third convex curved portion 25. More specifically, the electrode portion 30 is provided between the apex 24b of the second convex curved portion 24 and the bottom 25a of the third convex curved portion 25. More specifically, the electrode portion 30 is provided on the second concave curved portion 28. The electrode portion 30 includes a first electrode portion 31 and a second electrode portion 32 provided at a position away from the first electrode portion 31. In this embodiment, an electric current is passed between the first electrode portion 31 and the second electrode portion 32 through the skin, thereby applying an electric stimulus to the skin. The first electrode portion 31 and the second electrode portion 32 are disposed at a position closer to the apex 24b of the second convex curved portion 24 than the apex 25b of the third convex curved portion 25.
[0046] The first electrode portion 31 is provided between the apex 24b of the second convex portion 24 and the apex 28a of the second concave portion 28. The first electrode portion 31 is formed of a single metal plate. From the viewpoint of improving safety, the first electrode portion 31 may contain a metal such as titanium. As shown in FIG. 5, the first electrode portion 31 includes a first exposed portion 31a, a first side wall portion 31b, and a first fixed portion 31c.
[0047] The first exposed portion 31a has a plate shape. The first exposed portion 31a has an outer surface that contacts the skin and is an exposed surface, and an inner surface disposed on the opposite side to the outer surface. The first exposed portion 31a has an elliptical shape when viewed from a direction perpendicular to the exposed surface of the first exposed portion 31a (short side direction Y). The first side wall portion 31b extends from an end of the first exposed portion 31a toward the main body portion 10 when viewed from the short side direction Y, forming an elliptical cylinder. The first fixed portion 31c extends from an end of the first side wall portion 31b opposite to the intersection point between the first exposed portion 31a and the first side wall portion 31b in the short side direction Y so as to spread outward in parallel with the first exposed portion 31a. The first fixed portion 31c is sandwiched and fixed between the support portion 15 and the first insulating member 35 via a spring receiver.
[0048] The second electrode portion 32 is provided between the top portion 28a of the second concave portion 28 and the bottom portion 25a of the third convex portion 25. The second electrode portion 32 is formed of a single metal plate. From the viewpoint of improving safety, the second electrode portion 32 may contain a metal such as titanium. As shown in FIG. 6, the second electrode portion 32 includes a second exposed portion 32a, a second side wall portion 32b, and a second fixed portion 32c.
[0049] The second exposed portion 32a is plate-shaped. The second exposed portion 32a has an outer surface that contacts the skin and is an exposed surface, and an inner surface that is disposed on the opposite side to the outer surface. The second exposed portion 32a has an elliptical shape when viewed from a direction perpendicular to the exposed surface of the second exposed portion 32a (short side direction Y). The second side wall portion 32b extends from an end of the second exposed portion 32a toward the main body portion 10 when viewed from the short side direction Y, forming an elliptical cylinder. The second fixed portion 32c extends from an end of the second side wall portion 32b opposite to the intersection point between the second exposed portion 32a and the second side wall portion 32b in the short side direction Y so as to spread outward in parallel with the second exposed portion 32a. The second fixed portion 32c is sandwiched and fixed between the support portion 15 and the second insulating member 36 via a spring receiver.
[0050] The beauty tool 1 may include a first elastic portion 33. The first elastic portion 33 is provided between the first exposed portion 31a and the support portion 15. The first elastic portion 33 is connected to the support portion 15. The first elastic portion 33 is in contact with the inner surface of the first exposed portion 31a. The first elastic portion 33 is electrically connected to a control circuit on the control circuit board. In this embodiment, the first elastic portion 33 is made of a conductive elastic member such as a coil. The first exposed portion 31a and the first elastic portion 33 are in strong contact with each other due to the elastic force of the elastic member, so that the electrical connection between the first exposed portion 31a and the control circuit can be stabilized.
[0051] The beauty tool 1 may include a second elastic portion 34. The second elastic portion 34 is provided between the second exposed portion 32a and the support portion 15. The second elastic portion 34 is connected to the support portion 15. The second elastic portion 34 is in contact with the inner surface of the second exposed portion 32a. The second elastic portion 34 is electrically connected to a control circuit on the control circuit board. In this embodiment, the second elastic portion 34 is made of a conductive elastic member such as a coil. The second exposed portion 32a and the second elastic portion 34 are in strong contact with each other due to the elastic force of the elastic member, so that the electrical connection between the second exposed portion 32a and the control circuit can be stabilized.
[0052] A first recess 31d is provided on the exposed surface of the first electrode section 31. The depth of the first recess 31d is formed to become deeper from the outer periphery of the exposed surface of the first electrode section 31 toward the inside when viewed from a direction perpendicular to the exposed surface of the first electrode section 31. The first recess 31d is recessed from the end of the treatment section 20 toward the inside when viewed from the thickness direction Z.
[0053] A second recess 32d is provided on the exposed surface of the second electrode section 32. The depth of the second recess 32d is formed to become deeper from the outer periphery of the exposed surface of the second electrode section 32 toward the inside when viewed from a direction perpendicular to the exposed surface of the second electrode section 32. The second recess 32d is recessed from the end of the treatment section 20 toward the inside when viewed from the thickness direction Z.
[0054] The first recess 31d and the second recess 32d can hold a medicine such as gel. Therefore, when the electrode unit 30 contacts the skin, the stimulation is uniform and the electrical stimulation can be applied stably to the skin. Therefore, the beauty tool 1 according to this embodiment can provide the effects of massage and electrical stimulation at the same time.
[0055] The drug may be a gel containing water and a moisturizer. By disposing the gel between the skin and the electrode, a current can be effectively passed from the electrode portion 30 to the skin via the water in the gel. An example of the moisturizer is glycerin.
[0056] A first insulating member 35 is provided between the housing 21 and the first electrode portion 31. Furthermore, a second insulating member 36 is provided between the housing 21 and the second electrode portion 32. The first insulating member 35 surrounds the periphery of the first electrode portion 31, and the second insulating member 36 surrounds the periphery of the second electrode portion 32. The first insulating member 35 and the second insulating member 36 have an elliptical shape when viewed from the Y direction. The first insulating member 35 and the second insulating member 36 contain an insulating material such as a resin or an elastomer.
[0057] The first electrode portion 31 and the second electrode portion 32 are separated by a first insulating member 35 and a second insulating member 36 when viewed from the short side direction Y. This makes it possible for the first insulating member 35 and the second insulating member 36 to prevent electricity from flowing from the first electrode portion 31 and the second electrode portion 32 to the metal housing 21.
[0058] 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 recess 37 is formed by the outer surface of the housing 21, which is the bottom of the recess 37, being lower than the tip of the outer surface of the first insulating member 35. The depth R1 of the recess 37 is, for example, 0.4 mm. 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, which is the bottom of the recess 38, being lower than the tip of the outer surface of the second insulating member 36, so that the recess 38 is formed. The depth R2 of the recess 38 is, for example, 0.4 mm. The recess 37 and the recess 38 can form a liquid pool that holds a drug such as a gel. The drug held in recesses 37 and 38 is supplied evenly to electrode portion 30 during use, so that when electrode portion 30 comes into contact with the skin, stimulation is uniform and electrical stimulation can be applied to the skin stably.
[0059] As shown in Figs. 4 to 6, the beauty tool 1 may include a heating unit 40 that heats at least a part of the treatment unit 20. By providing the heating unit 40 to the treatment unit 20, the treatment unit 20 that contacts the user's skin is warmed by the heating unit 40, so that a warm feeling can be given to the skin. The heating unit 40 is provided inside the housing 21. Specifically, the heating unit 40 is provided between the housing 21 and the support unit 15. The heating unit 40 may be installed on the support unit 15 with the heating surface of the heating unit 40 facing the inner surface of the housing 21.
[0060] The heating unit 40 is desirably in the form of a thin plate overall, and is desirably capable of being flexibly deformed to fit the shape of the portion in which the heating unit 40 is to be installed. The structure that can be adopted for the heating unit 40 is not particularly limited, but may be, for example, a sheet-shaped heater with a built-in sheathed heater. The heating unit 40 is electrically connected to a control circuit on a control circuit board.
[0061] The heating unit 40 is installed inside at least one of the convex curved portions 22. For example, it is desirable to install the heating unit 40 inside the second convex curved portion 24, which is assumed to be most likely to come into contact with the skin of the user. In this case, the heating unit 40 extends from at least the vicinity of the bottom portion 24a, via the apex portion 24b, to the vicinity of the bottom portion 24c.
[0062] 4, the heating unit 40 is not only installed inside the second convex curved portion 24, but is also installed continuously from the second convex curved portion 24 to the third convex curved portion 25. In this case, the range heated by the heating unit 40 in the treatment area 20 extends not only to the periphery of the second convex curved portion 24 but also to the periphery of the third convex curved portion 25.
[0063] Furthermore, the heating section 40 may heat not only the housing 21 but also the electrode section 30. In this case, the electrode section 30 can impart an electrical stimulus to the skin while the heating section 40 gives a warm sensation to the skin.
[0064] 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. A recess 37 is provided around the first electrode portion 31, and a recess 38 is provided around the second electrode portion 32. However, it is sufficient that at least one recess is provided in at least one selected from the group consisting of the exposed surface of the first electrode portion 31, the periphery of the exposed surface of the first electrode portion 31, the exposed surface of the second electrode portion 32, and the periphery of the exposed surface of the second electrode portion 32.
[0065] In this embodiment, the first electrode section 31 is fixed by the first fixing section 31c, but the first elastic section 33 may support the first electrode section 31 so that the exposed surface of the first electrode section 31 swings in a direction perpendicular to the exposed surface of the first electrode section 31. As a result, when the beauty tool 1 is placed against the skin, the first electrode section 31 is pressed and pushed into the skin, forming a recess with the exposed surface of the first electrode section 31 as the bottom surface. Since the medicinal agent is held in the recess, the electrical stimulation can be applied to the skin stably.
[0066] In the present embodiment, the second electrode section 32 is fixed by the second fixing section 32c, but the second elastic section 34 may support the second electrode section 32 such that the exposed surface of the second electrode section 32 swings in a direction perpendicular to the exposed surface of the second electrode section 32. As a result, when the beauty tool 1 is placed against the skin, the second electrode section 32 is pressed and pushed into the skin, forming a recess with the exposed surface of the second electrode section 32 as the bottom surface. Since the medicinal agent is held in the recess, the electrical stimulation can be applied to the skin stably.
[0067] [Second embodiment] Next, a beauty tool 1 according to a second embodiment will be described with reference to Fig. 7 and Fig. 8. The beauty tool 1 according to this embodiment is different from the beauty tool 1 according to the first embodiment in the shape of the electrode section 30. Other than this, the beauty tool 1 according to the first embodiment is the same as the beauty tool 1 according to the first embodiment, so a description thereof will be omitted.
[0068] Specifically, in the beauty tool 1 according to the first embodiment, the depth of the first recess 31d is formed to increase inward from the outer periphery of the exposed surface of the first electrode portion 31. The depth of the second recess 32d is formed to increase inward from the outer periphery of the exposed surface of the second electrode portion 32.
[0069] On the other hand, in the beauty tool 1 according to this embodiment, as shown in Fig. 7, a plurality of third recesses 31e are provided on the exposed surface of the first electrode portion 31. Also, as shown in Fig. 8, a plurality of fourth recesses 32e are provided on the exposed surface of the second electrode portion 32.
[0070] In this embodiment, by providing multiple recesses on the exposed surface of the first electrode portion 31 and the exposed surface of the second electrode portion 32, the drug is retained in the multiple recesses, and the drug is retained between the skin and the skin, allowing stable electrical stimulation to be applied to the skin via the drug.
[0071] The depth and the diameter of the opening of each of the plurality of third recesses 31e and 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 be smaller than the diameter of the short 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 be smaller than the diameter of the short axis of the exposed surface of the second electrode portion 32. Note that the short axis here means the shortest line segment that passes through the center of the first electrode portion 31 or the second electrode portion 32 and connects the ends of the exposed surface of the first electrode portion 31 or the second electrode portion 32. In addition, the number of the third recesses 31e provided in the first electrode portion 31 and the number of the fourth recesses 32e provided in the second electrode portion 32 are not particularly limited.
[0072] Moreover, the multiple third recesses 31e may be provided on at least a part of the exposed surface of the first exposed portion 31a. Specifically, the multiple third recesses 31e may be provided on the entire exposed surface of the first exposed portion 31a, or may be provided on a part of the first exposed portion 31a, such as the center. Similarly, the multiple fourth recesses 32e may be provided on at least a part of the exposed surface of the second electrode portion 32. Specifically, the multiple fourth recesses 32e may be provided on the entire exposed surface of the second electrode portion 32, or may be provided on a part of the second electrode portion 32, such as the center.
[0073] 7 and 8, the first exposed portion 31a of the first electrode portion 31 and the second exposed portion 32a of the second electrode portion 32 are not gently curved as in the first embodiment. However, a plurality of third recesses 31e may be provided on the exposed surface of the first electrode portion 31, and the depth of the first recesses 31d may be formed so as to become deeper from the outer periphery of the exposed surface of the first electrode portion 31 toward the inside. Similarly, a plurality of fourth recesses 32e may be provided on the exposed surface of the second electrode portion 32, and the depth of the second recesses 32d may be formed so as to become deeper from the outer periphery of the exposed surface of the second electrode portion 32 toward the inside.
[0074] In this embodiment, a plurality of third recesses 31e are provided on the exposed surface of the first electrode portion 31, and a plurality of fourth recesses 32e are provided on the exposed surface of the second electrode portion 32. However, it is sufficient that the plurality of recesses are provided on at least one of the exposed surface of the first electrode portion 31 and the exposed surface of the second electrode portion 32.
[0075] [Third embodiment] Next, a beauty tool 1 according to a third embodiment will be described with reference to Figures 9 and 10. The beauty tool 1 according to this embodiment is different from the beauty tool 1 according to the first embodiment in the shapes of the first insulating member 35 and the second insulating member 36. Other than this, the beauty tool 1 according to the first embodiment is the same as the beauty tool 1 according to the first embodiment, so a description thereof will be omitted.
[0076] Specifically, in the above embodiment, the first insulating member 35 is provided on the housing 21 such that the edge of the exposed surface of the first electrode portion 31 and the outer surface of the first insulating member 35 are at the same height. Also, in the above embodiment, the second insulating member 36 is provided on the housing 21 such that the edge of the exposed surface of the second electrode portion 32 and the outer surface of the second insulating member 36 are at the same height.
[0077] On the other hand, in the beauty tool 1 according to this embodiment, as shown in Fig. 9, a first protrusion 35a is provided around the exposed surface of the first electrode section 31, protruding outward in a direction perpendicular to the exposed surface of the first electrode section 31 more than the exposed surface of the first electrode section 31. Also, as shown in Fig. 10, a second protrusion 36a is provided around the exposed surface of the second electrode section 32, protruding outward in a direction perpendicular to the exposed surface of the second electrode section 32 more than the exposed surface of the second electrode section 32. In this embodiment, the first protrusion 35a is formed by a first insulating member 35. The second protrusion 36a is formed by a second insulating member 36.
[0078] By providing the first convex portion 35a, a first recess 31d having a depth increased by an amount corresponding to the protrusion of the first convex portion 35a is formed on the exposed surface of the first electrode portion 31. In addition, by providing the second convex portion 36a, a second recess 32d having a depth increased by an amount corresponding to the protrusion of the second convex portion 36a is formed on the exposed surface of the second electrode portion 32.
[0079] 9, the first protrusion 35a may protrude outward beyond the outer periphery of the housing 21 in a direction perpendicular to the outer periphery of the housing 21. The second protrusion 36a may protrude outward beyond the outer periphery of the housing 21 in a direction perpendicular to the outer periphery of the housing 21 as shown in FIG.
[0080] By providing the first convex portion 35a, a recess 37 whose depth is increased by the amount that the first convex portion 35a protrudes is provided around the first electrode portion 31. In addition, by providing the second convex portion 36a, a recess 38 whose depth is increased by the amount that the second convex portion 36a protrudes is provided around the second electrode portion 32.
[0081] Therefore, since the medicinal agent is held in these recesses, the medicinal agent is held between the skin and the skin, and an electrical stimulus can be stably applied to the skin via the medicinal agent.
[0082] As shown in Figs. 11 and 12, the first convex portion 35a may have a notch portion 35b at one end when viewed from a direction perpendicular to the exposed surface of the first electrode portion 31. Also, as shown in Figs. 11 and 13, the second convex portion 36a may have a notch portion 36b at one end when viewed from a direction perpendicular to the exposed surface of the second electrode portion 32. With this, when a medicine such as gel is applied to the skin and the skin is massaged, the medicine moves onto the exposed surfaces of the first electrode portion 31 and the second electrode portion 32 through the notch portion 35b and the notch portion 36b. The medicine on the exposed surfaces is blocked by the first convex portion 35a and the second convex portion 36a, and is thus prevented from leaking out of the first insulating member 35 and the second insulating member 36. Therefore, the medicine can be stably held in these recesses.
[0083] The notch 35b may be provided at an end of the first insulating member 35 in the thickness direction Z. The notch 36b may be provided at an end of the second insulating member 36 in the thickness direction Z. Since the beauty tool 1 is often moved in the thickness direction Z while being in contact with the skin, providing the notch 35b and the notch 36b at the above-mentioned positions makes it easier to hold the medicinal agent on the electrode portion 30.
[0084] The position where the notch 35b is provided for the first electrode 31 and the position where the notch 36b is provided for the second electrode 32 may be the same or different. However, if these positions are the same, it is preferable because when the beauty tool 1 is moved while being in contact with the skin, the medicinal agent is easily retained on the exposed surfaces of the first electrode 31 and the second electrode 32 via the notch 35b and the notch 36b.
[0085] In this embodiment, an example in which both the first convex portion 35a and the second convex portion 36a are provided has been described, but at least one of the first convex portion 35a and the second convex portion 36a may be provided.
[0086] In the present embodiment, the example in which the first protrusion 35a is provided with the notch 35b and the second protrusion 36a is provided with the notch 36b has been described. However, it is sufficient that the notch is provided in at least one of the first protrusion 35a and the second protrusion 36a.
[0087] As described above, the beauty tool 1 according to the present embodiment includes a flat main body 10, a treatment section 20, and an electrode section 30. The treatment section 20 is provided at the end of the main body 10 when viewed from the thickness direction Z of the main body 10, and the outer circumferential edge 20a is formed to have at least one convex curved section 22 and at least one concave curved section 26. The electrode section 30 is provided at the end of the treatment section 20 when viewed from the thickness direction Z, and includes a first electrode section 31 and a second electrode section 32 provided at a position away from the first electrode section 31. At least one recess is provided in at least one selected from the group consisting of the exposed surface of the first electrode section 31, the periphery of the exposed surface of the first electrode section 31, the exposed surface of the second electrode section 32, and the periphery of the exposed surface of the second electrode section 32.
[0088] This allows a medicine such as gel to be held in the recess, and when the electrode section 30 comes into contact with the skin, the stimulation is uniform and the electrical stimulation can be applied stably to the skin. Therefore, the beauty tool 1 according to this embodiment can provide the effects of massage and electrical stimulation at the same time.
[0089] Also, as disclosed herein, the 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. The depth of the first recess 31d may be formed so as to become deeper from the outer periphery of the exposed surface of the first electrode portion 31 toward the inside. The depth of the second recess 32d may be formed so as to become deeper from the outer periphery of the exposed surface of the second electrode portion 32 toward the inside.
[0090] This allows the drug to be held in the first recess 31d and the second recess 32d. Therefore, when the electrode section 30 comes into contact with the skin, the stimulation is uniform and the electrical stimulation can be applied to the skin stably.
[0091] Furthermore, as disclosed herein, the at least one recess may include a plurality of third recesses 31e provided in the exposed surface of the first electrode portion 31 and a plurality of fourth recesses 32e provided in the exposed surface of the second electrode portion 32.
[0092] This allows the medicine to be held in the third recess 31e and the fourth recess 32e. Therefore, when the electrode section 30 comes into contact with the skin, the stimulation is uniform and the electrical stimulation can be applied to the skin stably.
[0093] Also, 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 beyond the exposed surface of the first electrode portion 31. Also, 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 beyond the exposed surface of the second electrode portion 32.
[0094] As a result, recesses are formed on the exposed surfaces of the first electrode section 31 and the second electrode section 32, and the drug can be held in the recesses. Therefore, when the electrode section 30 comes into contact with the skin, the stimulation is uniform and the electrical stimulation can be applied stably to the skin.
[0095] Also, as disclosed herein, the first protrusion 35a may have a notch 35b at one end when viewed from a direction perpendicular to the exposed surface of the first electrode portion 31. The second protrusion 36a may have a notch 36b at one end when viewed from a direction perpendicular to the exposed surface of the second electrode portion 32.
[0096] As a result, when a drug such as gel is applied to the skin and the skin is massaged, the drug moves onto the exposed surfaces of the first electrode section 31 and the second electrode section 32 through the notches 35b and 36b. The drug on the exposed surfaces is blocked by the first convex section 35a and the second convex section 36a, and is prevented from leaking out of the first insulating member 35 and the second insulating member 36. Therefore, recesses are formed on the exposed surfaces of the first electrode section 31 and the second electrode section 32, and the drug can be held in the recesses. Therefore, when the electrode section 30 contacts the skin, the stimulation is uniform, and the skin can be stably stimulated.
[0097] Also, as disclosed herein, the beauty tool 1 may further include a heating unit 40 that heats at least a portion of the treatment unit 20. The treatment unit 20 may include a housing 21 that is provided with at least one convex curved portion 22 and at least one concave curved portion 26 and includes a metal. The first convex portion 35a and the second convex portion 36a may include an insulating material.
[0098] As a result, the treatment section 20 in contact with the user's skin is heated by the heating section 40, providing a warm sensation to the skin. Furthermore, since the first convex section 35a and the second convex section 36a are formed from an insulating material, short-circuiting between the treatment section 20 and the electrode section 30 is suppressed, and the medicinal agent can be held in the recess. In this way, the first convex section 35a and the second convex section 36a serve both to hold the medicinal agent and to suppress short-circuiting, allowing the beauty tool 1 to be made compact.
[0099] Furthermore, as disclosed herein, the beauty tool 1 may further include a first elastic portion 33 and a second elastic portion 34. The first elastic portion 33 may support the first electrode portion 31 such that the exposed surface of the first electrode portion 31 oscillates in a direction perpendicular to the exposed surface of the first electrode portion 31. The second elastic portion 34 may support the second electrode portion 32 such that the exposed surface of the second electrode portion 32 oscillates in a direction perpendicular to the exposed surface of the second electrode portion 32.
[0100] As a result, by pressing the first electrode section 31 and the second electrode section 32, a recess is formed on the exposed surface of these electrodes, and the drug can be held in the recess. Therefore, when the electrode section 30 contacts the skin, the stimulation is uniform, and the electrical stimulation can be applied to the skin stably.
[0101] Also, as disclosed herein, at least one convex curved portion 22 may include a first convex curved portion 23, a second convex curved portion 24, and a third convex curved portion 25. The electrode portion 30 may be provided between the apex 24b of the second convex curved portion 24 and the apex 25b of the third convex curved portion 25. The distance between the apex 24b of the second convex curved portion 24 and the apex 25b of the third convex curved portion 25 may be longer than the distance between the apex 23b of the first convex curved portion 23 and the apex 24b of the second convex curved portion 24.
[0102] This allows a physical massage to be given to the jaw area while the device is in contact with the area from the cheek side to the throat side, and also allows electrical stimulation to be given to the jaw area.
[0103] Furthermore, as disclosed herein, the first electrode portion 31 and the second electrode portion 32 may be disposed at a position closer to the apex 24b of the second convex curved portion 24 than to the apex 25b of the third convex curved portion 25.
[0104] This makes it easier to bring the electrode section 30 into contact with the desired location along the facial line to which electrical stimulation is to be applied, and allows even users with small faces to appropriately apply electrical stimulation to the facial muscles, thereby enabling effective EMS training of the facial muscles.
[0105] The beauty tool 1 may include a flat main body 10 that massages the skin with its edge, an electrical stimulation unit that applies electrical stimulation, and a recess that can hold a conductive agent in the electrical stimulation unit or in the vicinity of the electrical stimulation unit. Even with this type of beauty tool 1, the agent can be held in the recess, and the stimulation can be even when the electrode unit 30 contacts the skin, so that the electrical stimulation can be applied stably to the skin.
[0106] The electrical stimulation unit may be provided with one or more electrode units 30. This makes it possible to apply electrical stimulation to the skin.
[0107] Furthermore, the electrode surface of the electrode section 30 may have an R. Such an electrode section 30 can also hold a drug on the electrode surface.
[0108] The electrode surface of the electrode section 30 may have an uneven shape. Such an electrode section 30 can also hold a drug on the electrode surface.
[0109] Furthermore, a convex portion may be provided around the electrode portion 30. When such a convex portion is provided, the drug can be held in the vicinity of the convex portion.
[0110] The above-mentioned convex parts may be only on three sides around the electrode part 30. When the convex parts are provided in this way, the drug moves to the electrode surface from the part where the convex parts are not provided, and the drug is blocked by the convex parts, as described above. Therefore, when the electrode part 30 contacts the skin, the stimulation is uniform, and the skin can be stably stimulated.
[0111] The beauty tool 1 may also include a heating section that provides a warm sensation to the skin when the skin is massaged using the main body section 10. This allows the skin to be given a warm sensation.
[0112] In addition, the edge of the flat main body 10 that massages the skin may be made of metal so as to be able to transfer heat from the heating unit 40, and the protrusions around the electrode unit 30 may be made of an insulating material. This allows the metal that contacts the user's skin to be warmed by the heating unit 40, giving the skin a warm feeling. Since the protrusions are made of an insulating material, short-circuiting between the metal and the electrode unit 30 is suppressed, and the medicine can be held in the recesses. In this way, the protrusions serve both to hold the medicine and to suppress short-circuiting, so the beauty tool 1 can be made compact.
[0113] The electrode section 30 may be supported by an elastic member. By pressing the electrode section 30, a recess is formed on the electrode surface, and the drug can be held in the recess. Therefore, when the electrode section 30 contacts the skin, the stimulation is uniform, and the skin can be stably stimulated.
[0114] The beauty tool 1 may also include a vibration unit that imparts vibrations to the skin when the skin is massaged using the main body 10. This allows the beauty tool 1 to be mechanically vibrated, so that a physical stimulus can be imparted to the skin without the user directly moving the beauty tool 1 while the treatment unit 20 is in contact with the skin.
[0115] The beauty tool 1 may also include an electrical stimulation control unit that controls the degree of electrical stimulation by determining the state of the agent held in the recess capable of holding the conductive agent. This allows the degree of electrical stimulation to be changed according to the state of the agent held, so that the user can receive the optimal electrical stimulation on their skin.
[0116] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.
[0117] For example, in the above embodiment, an example was described in which the first insulating member 35 protrudes above the same plane as the exposed surface of the first electrode portion 31. However, at least one recess may include a recess in which the tip of the outer surface of the first insulating member 35 is recessed below the exposed surface of the first electrode portion 31. Similarly, an example was described in which the second insulating member 36 protrudes above the same plane as the exposed surface of the second electrode portion 32. However, at least one recess may include a recess in which the tip of the outer surface of the second insulating member 36 is recessed below the exposed surface of the second electrode portion 32. As a result, at least one of the first insulating member 35 and the second insulating member 36 forms the bottom of the recess. Therefore, a drug such as gel can be held in this recess.
[0118] In the above embodiment, the electrode unit 30 includes two electrode units, the first electrode unit 31 and the second electrode unit 32. However, the electrode unit 30 may include three or more electrode units. Specifically, the electrode unit 30 may further include a third electrode unit provided at a position away from the first electrode unit 31 and the second electrode unit 32. The third electrode unit may be disposed at a position closer to the apex 25b of the third convex curved portion 25 than the apex 24b of the second convex curved portion 24. This makes the distance between the first electrode unit 31 and the third electrode unit longer than the distance between the first electrode unit 31 and the second electrode unit 32. Therefore, by passing a current between the first electrode unit 31 and the third electrode unit, it is possible to apply electrical stimulation to large muscles such as thigh muscles.
[0119] In addition, the housing and other detailed specifications (shape, size, layout, etc.) can also be changed as appropriate. [Industrial Applicability]
[0120] As described above, the beauty tool according to the present disclosure is capable of holding a drug between the beauty tool and the skin and stably applying an electrical stimulus to the skin via the drug. Specifically, the beauty tool can be applied to beauty tools for commercial and home use. [Explanation of symbols]
