[0012] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted.

[0013] The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0014] Furthermore, in the following embodiments, an electric razor that cuts the user's beard (hair) is used as an example of a hair removal device.

[0015] Furthermore, in the following embodiments, the direction in which the multiple blade blocks are arranged side by side will be described as the X direction (first direction: front-to-back direction: shaving direction), and the direction in which each blade block extends will be described as the Y direction (second direction: left-to-right direction: width direction).

[0016] Furthermore, the vertical direction when the head unit (electric shaver) is positioned so that the skin contact surface faces upward will be described as the Z direction (vertical direction of the head unit 30). In this embodiment, the skin contact surface of the blade unit is composed of the surfaces (outer surfaces) of the outer blades of multiple blade blocks, and as a whole, it can be approximated as a curved surface that is convex outward. Therefore, in the following embodiments and their modifications, the state in which the head unit (electric shaver) is positioned so that the skin contact surface faces upward is described as the state in which the skin contact surface faces upward when the head unit (electric shaver) is positioned so that the skin contact surface faces upward, and the tangent plane at the point that protrudes outward the most on the curved surface approximating the skin contact surface of the blade unit is a horizontal plane.

[0017] Furthermore, in the following embodiments, during normal use, when the user is holding the grip portion 111 of the electric shaver 1, the side facing the user is defined as the front side (forward in the X direction) of the electric shaver 1 and will be described accordingly.

[0018] (Embodiment 1) First, with reference to Figures 1 to 3, the general configuration of the hair removal device set 100 according to Embodiment 1 will be described.

[0019] As shown in Figures 1 and 2, the hair removal device set 100 according to this embodiment comprises an electric razor (hair removal device) 1 having a blade portion 331 capable of removing hair provided on the main body portion 1a, and an attachment 40 that is detachably attached to the electric razor 1.

[0020] Furthermore, the main body 1a of this electric razor 1 is provided with a treatment section 34 that can be used to treat the skin S, separate from the blade section 331.

[0021] Thus, the electric razor 1 included in the hair removal device set 100 has a hair removal function that cuts (removes hair from) the beard on the skin S with the blade part 331, and a treatment function that performs treatment on the skin S by applying the treatment surface 340 of the treatment part 34 to the skin S.

[0022] Examples of treatments performed on the skin S by the treatment unit 34 include applying a weak electric current to the skin S, applying heat to the skin S, and vibrating the skin S. In this case, the treatment unit 34 may have multiple treatment functions.

[0023] In this embodiment, the attachment 40 is detachably attached to the electric razor 1 having such functions.

[0024] As shown in Figure 3, the attachment 40 comprises an attachment body 41 that is detachably attached to the electric razor (hair removal device) 1, and a holding part 60 provided on the attachment body 41.

[0025] As shown in Figures 1 and 3, the attachment 40 is configured such that when the attachment body 41 is attached to the electric razor (hair removal device) 1, the soft sheet body 50 covers the treatment surface 340 of the treatment section 34, while the holding section 60 holds the soft sheet body 50. For the soft sheet body 50, known commercially available products such as cotton sheets, sponge-like sheets, or soft cloth can be used. It is also possible to prepare a dedicated soft sheet body 50 to be held by the holding section 60.

[0026] Furthermore, when performing treatment on the skin S with the treatment unit 34, the soft sheet body 50 held by the electric razor 1 can be applied to the skin S for use.

[0027] Next, with reference to Figures 4 to 7, the general configuration of the electric razor 1 according to Embodiment 1 will be described.

[0028] As shown in Figures 4 to 7, the electric razor (hair removal device) 1 according to this embodiment comprises a razor body 10, a head portion 30 supported by the razor body 10, and a connecting mechanism 20 that connects the head portion 30 to the razor body 10. The head portion 30 is provided with a blade portion 331 capable of cutting beards (hair) and a treatment portion 34 capable of performing treatment on the skin S. Thus, in this embodiment, the main body portion 1a of the electric razor 1 is formed by the razor body 10, the connecting mechanism 20, and the head portion 30 (excluding the blade portion 331 and the treatment portion 34).

[0029] The razor body 10 is equipped with a body housing 11, which is a cylindrical shape that is elongated vertically and has approximately the same diameter. The cylindrical portion of the body housing 11 with approximately the same diameter serves as a grip portion 111 that can be held by the user when using the electric razor 1.

[0030] The main housing 11 can be formed by joining multiple divided parts together using screws or the like, and a cavity is formed inside the main housing 11. Various electrical components, such as a rechargeable battery, are housed in the cavity formed inside the main housing 11. The multiple divided parts can be formed using materials such as synthetic resin or metal.

[0031] Furthermore, as shown in Figure 4, a push-type power switch 1111 for operating the electric razor 1 (turning the power on and off) is formed on the grip portion 111 of the main body housing 11.

[0032] Furthermore, in this embodiment, the grip portion 111 has a changeover switch 1112 for switching the operating state of the treatment portion 34. If the treatment portion 34 is an electrode that applies a weak electric current to the skin S, this changeover switch 1112 can be a current changeover switch that switches between, for example, three levels ("strong", "weak", and "off"). Also, the grip portion 111 has a temperature changeover switch 1113 for switching the temperature of the treatment portion 34. This temperature changeover switch 1113 can be a switch that switches the temperature of the treatment portion 34 between, for example, three levels ("high", "low", and "off").

[0033] In this embodiment, push-type switches are given as examples of various switches, but these switches may be composed of slide-type or other types of switches.

[0034] Furthermore, in this embodiment, the power switch 1111 is formed on the front of the main body housing 11 (grip portion 111), that is, on the front of the electric shaver 1. This allows the user to operate the power switch 1111 with their thumb while holding the grip portion 111 of the electric shaver 1.

[0035] Similarly, the changeover switch 1112 and the temperature changeover switch 1113 are also formed on the front of the main body housing 11 (grip portion 111), that is, on the front of the electric shaver 1. The three switches are arranged in a line along the longitudinal direction of the main body housing 11 (grip portion 111).

[0036] Furthermore, when the treatment section 34 is used as an electrode, it is preferable that a counter electrode section 1114, for example made of metal, be placed on the back of the grip section 111, as shown in Figure 6. By placing such a counter electrode section 1114, a closed circuit can be formed between the electrode as the treatment section 34 and the counter electrode section 1114 via the user's body when the electric shaver 1 is used. When the electric shaver 1 is used with the closed circuit formed, a weak current flows more easily through the user's body, making it possible to apply a voltage with the same potential (a voltage that is approximately constant) to the skin S on which hair removal is performed at all times.

[0037] When such a counter electrode portion 1114 is provided on the grip portion 111, it is preferable that the counter electrode portion 1114 be elongated and aligned with the longitudinal direction of the grip portion 111. This allows the user's palm and fingers to more reliably come into contact with the counter electrode portion 1114 when they grasp the grip portion 111 with their hand. As a result, the user can bring their palm and fingers into contact with the counter electrode portion 1114 simply by grasping the grip portion 111 with their hand. In other words, it becomes possible to enhance a weak electrical stimulation effect by utilizing the grip portion 111 that the user grasps. The material of the counter electrode portion 1114 is not limited to metal; for example, it may be a conductive resin, or an insulating resin with a metal plating coating on its surface.

[0038] A connecting mechanism 20 for supporting the head portion 30 on the razor body 10 is fixed to the upper part of the main body housing 11. In this embodiment, the connecting mechanism 20 is cylindrical in shape, with a diameter that widens towards the top, and a trimmer unit 21 is provided at the rear of the connecting mechanism 20. This trimmer unit can also be provided on the head portion 30 or the razor body 10 instead of the connecting mechanism 20. It is also possible to have an electric razor 1 without a trimmer unit.

[0039] Then, with the connecting mechanism 20 fixed to the main body housing 11, the head portion 30 is supported by the connecting mechanism 20, so that the head portion 30 is supported by the razor body 10. At this time, the head portion 30 is supported by the razor body 10 so as to be tilted upward and forward, with the extending direction of the razor body 10 substantially aligned with the vertical direction. In this way, when the extending direction of the razor body 10 is aligned with the vertical direction, the part of the blade portion 331 that contacts the skin S (skin contact surface 33a, described later) is tilted forward and downward with respect to the horizontal plane, making it easier to apply the skin contact surface 33a to the user's skin S when using the electric razor 1 by gripping the grip portion 111.

[0040] It is also possible to configure the head portion 30 so that it is not tilted relative to the razor body 10.

[0041] Furthermore, it is possible to support the head portion 30 on the razor body 10 (connecting mechanism 20) in a state in which it can move relative to the razor body 10 in at least one direction (such as reciprocating linear motion or oscillation).

[0042] In this embodiment, as shown in Figure 7, the head portion 30 is connected to the connecting mechanism 20 by a shaft 22 that extends in the front-rear direction of the head portion 30, with the head portion 30 positioned so that the skin contact surface 33a faces upward. That is, the head portion 30 is supported by the razor body 10 so that it can swing in the width direction of the head portion 30 relative to the razor body 10 about the shaft 22. This makes it possible to further improve the contact of the blade portion 331 with the skin S when using the electric razor 1, and to shave (remove) beards (hair) more efficiently.

[0043] Furthermore, it is also possible to configure the head portion 30 so that it can be moved relative to the razor body 10 in one or more directions other than the width direction of the head portion 30, or to configure it so that the head portion 30 cannot be moved relative to the razor body 10.

[0044] Next, the specific configuration of the head unit 30 will be described with reference to Figures 8 to 14.

[0045] In this embodiment, as shown in Figure 8, the head portion 30 is configured to be divided into multiple members, and includes a head base portion 31 attached to the connecting mechanism 20 and a head cover portion 32 that is detachably attached to the head base portion 31.

[0046] In this embodiment, release buttons 311 are provided at both the left and right ends of the head base 31 so as to be able to protrude and retract. By retracting these release buttons 311 inward, the attachment between the head cover 32 and the head base 31 is released.

[0047] The head base 31 is equipped with a base housing 310, and a retaining wall 312 for holding the treatment section 34 is attached to the front side of this base housing 310 by a screw 313.

[0048] Furthermore, as shown in Figure 14, a space is formed inside the base housing 310, and the drive mechanism 314 is housed within this space. In this embodiment, the drive mechanism 314 is equipped with a plurality of drive culms 315, and these drive culms 315 are housed within the head base 31 in such a state that they protrude upward from the head base 31. As such a drive mechanism 314, conventionally known devices can be used, such as a vibratory linear actuator or a drive mechanism composed of a rotary motor and a conversion mechanism that converts rotational motion into reciprocating linear motion.

[0049] On the other hand, as shown in Figure 9, the head cover portion 32 is equipped with a cover housing 321, and the blade unit 33 is attached to this cover housing 321.

[0050] Next, the specific configuration of the blade unit 33 will be described.

[0051] The blade unit 33 comprises three blade blocks and an outer blade case 334, and as shown in Figure 12, the three blade blocks are arranged so that their longitudinal directions coincide with the Y direction and they are aligned in the X direction.

[0052] Thus, in this embodiment, each blade block has a predetermined length and width, and these blade blocks are arranged such that their length direction substantially coincides with the Y direction (second direction: left-right direction) of the electric shaver 1, while their width direction substantially coincides with the X direction (first direction: front-back direction: shaving direction) of the electric shaver 1.

[0053] In this embodiment, the three blade blocks consist of two net blade blocks 332 and one slit blade block 333.

[0054] The net blade block 332 is primarily designed to remove bent-over whiskers (body hairs) and short, upright whiskers (body hairs). The slit blade block 333 is primarily designed to remove thin, long whiskers (body hairs).

[0055] In this embodiment, one slit blade block 333 is positioned in the center in the X direction, and two net blade blocks 332 are positioned on either side of the slit blade block 333.

[0056] As shown in Figure 8, the net blade block 332 comprises a net blade 3321 and an inner net blade 3322. In this embodiment, the net blade 3321 is formed in an inverted U-shape, curved so that the upper part is convex when viewed from the side (along the Y direction).

[0057] Furthermore, the net blade 3321 is formed with a slight curve along the Y direction (outer blade length direction) such that it is convex upwards when viewed from the front (viewed along the X direction). In addition, numerous circular cutting holes (not shown) are formed in this net blade 3321. It is also possible to configure the net blade 3321 not to be curved so that it is convex upwards when viewed from the front. For example, when the net blade 3321 is viewed from the front (viewed along the X direction), the top of the net blade 3321 can be made to be a straight line extending in the Y direction (outer blade length direction).

[0058] The inner net blade 3322 has an inverted U-shape that follows the curved shape of the net blade 3321 and is positioned inside the net blade 3321 (on the underside of the net blade 3321: opposite to the side of the net blade 3321 that contacts the skin S). This inner net blade 3322 is detachably attached to one of the multiple drive stalks 315. When the electric shaver 1 is turned on and the drive stalks 315 are driven with the inner net blade 3322 attached to the drive stalk 315 and positioned inside the net blade 3321, the inner net blade 3322 slides against the inner surface of the net blade 3321 and is displaced relative to the net blade 3321 (relative movement: reciprocating in the Y direction).

[0059] As shown in Figure 14, the slit blade block 333 comprises a slit outer blade 3331 and a slit inner blade 3332. In this embodiment, the slit outer blade 3331 is formed by bending into an inverted U-shape so that the upper part is convex when viewed from the side (along the Y direction). Furthermore, when viewed from the side (along the Y direction), the top surface of the slit outer blade 3331 is formed to be a substantially flat surface.

[0060] Furthermore, the slit outer blade 3331 is formed with a slight curve along the Y direction (outer blade length direction) such that it is convex upwards when viewed from the front (viewed along the X direction). Multiple slit-shaped cutting holes extending in the X direction are formed on this slit outer blade 3331, spaced apart in the Y direction. It is also possible to configure the slit outer blade 3331 not to be curved so that it is convex upwards when viewed from the front. For example, when viewed from the front (viewed along the X direction), it is possible to make the top of the slit outer blade 3331 a straight line extending in the Y direction (outer blade length direction). In other words, it is possible to form the slit outer blade 3331 so that its top surface is a flat surface.

[0061] The inner slit blade 3332 has an inverted U-shape that follows the curved shape of the outer slit blade 3331 and is positioned inside the outer slit blade 3331 (below the outer slit blade 3331: on the opposite side from the side of the outer slit blade 3331 that contacts the skin S). This inner slit blade 3332 is detachably attached to one of the multiple drive stalks 315 (a drive stalk 315 different from the drive stalk to which the inner net blade 3322 is attached). When the electric shaver 1 is turned on and the drive stalks 315 are driven with the inner slit blade 3332 attached to the drive stalk 315 and positioned inside the outer slit blade 3331, the inner slit blade 3332 slides against the inner surface of the outer slit blade 3331 and is displaced relative to the outer slit blade 3331 (relative movement: reciprocating in the Y direction).

[0062] Thus, the electric razor 1 according to this embodiment has the form of a reciprocating electric razor in which the net inner blade 3322 and the slit inner blade 3332 move back and forth relative to the net blade 3321 and the slit outer blade 3331. Therefore, in this embodiment, the blade section 331 comprises three outer blades (two net blades 3321 and one slit outer blade 3331) and three inner blades (two net inner blades 3322 and one slit inner blade 3332).

[0063] In this embodiment, all components except for two of the three inner net blades 3322 are mounted in a roughly frame-shaped outer blade case 334. At this time, each component may be mounted in the outer blade case 334 in a manner that prevents it from being detached, or it may be mounted in the outer blade case 334 in a manner that prevents it from being detached.

[0064] Furthermore, in this embodiment, the two net blade blocks 332 and the one slit blade block 333 are mounted on the outer blade case 334 in a state that allows them to float in the Z direction (vertical direction). This ensures that when the cover housing 321 (head cover portion 32) with the outer blade cassette 330 mounted on it is attached to the head base portion 31, each blade block floats separately and independently relative to the head portion 30. It is also possible to configure the blades so that one or more of the two net blade blocks 332 and the one slit blade block 333 do not float in the Z direction (vertical direction).

[0065] Furthermore, in this embodiment, as shown in Figure 8, the two net blades 3321 can be mounted in the outer blade case 334 without the net inner blade 3322 positioned inside them. On the other hand, the single slit outer blade 3331 is mounted in the outer blade case 334 with the slit inner blade 3332 positioned inside it. In this way, in this embodiment, the outer blade cassette 330 is formed by mounting the two net blades 3321 and the single slit blade block 333 in the outer blade case 334. This outer blade cassette 330 is then detachably mounted in the cover housing 321.

[0066] Specifically, as shown in Figure 9, the cover housing 321 has a substantially cylindrical peripheral wall portion 3211 with an upper opening 321a and a lower opening 321b. The outer blade cassette 330, with each outer blade facing upward, is inserted into the cover housing 321 from the lower opening 321b side, thereby mounting the outer blade cassette 330 to the cover housing 321. At this time, the outer blade cassette 330 is mounted to the cover housing 321 with the surface of each outer blade exposed from the upper opening 321a of the cover housing 321. Therefore, in this embodiment, the portion of the surface of each outer blade exposed from the upper opening 321a of the cover housing 321 is the portion exposed to the outside of the blade portion 331. That is, the portion of the surface of each outer blade exposed from the upper opening 321a of the cover housing 321 is the skin contact surface 33a that comes into contact with the user's skin (skin surface) S.

[0067] Furthermore, release buttons 3341 are formed on both the left and right ends of the outer blade case 334, and by operating these release buttons 3341, the attachment between the cover housing 321 and the outer blade cassette 330 is released.

[0068] In this embodiment, a roller 35 is rotatably supported in the cover housing 321. This roller 35 is formed in an elongated shape along the Y direction and is positioned between the front-facing net blade 3321 and the treatment section 34.

[0069] Furthermore, as shown in Figure 14, the roller 35 is supported by the cover housing 321 in a position where it protrudes above the skin contact surface 33a and the upper surface of the treatment area 34. When the user grasps the grip portion 111 with their hand and presses the skin contact surface 33a against the skin S, the roller 35 receives the greatest force applied to the head portion 30 against the skin S. In this way, the rotating roller 35 reduces frictional resistance, allowing the skin contact surface 33a to move across the skin S with less friction while being firmly pressed against the skin S.

[0070] As described above, in this embodiment, with the two net inner blades 3322 each mounted on the drive culm 315 that protrudes upward from the head base 31, the cover housing 321 with the outer blade cassette 330 mounted on it is attached to the head base 31. When the cover housing 321 with the outer blade cassette 330 mounted is attached to the head base 31 with the two net inner blades 3322 each mounted on the drive culm 315, the two net inner blades 3322 are positioned inside the corresponding net blades 3321.

[0071] This ensures that when the electric shaver 1 is turned on, each inner blade is displaced relative to the corresponding outer blade (relative movement: reciprocating motion in the Y direction).

[0072] Then, the electric shaver 1 is turned on, and with each inner blade displaced relative to the corresponding outer blade, the skin contact surface 33a of the blade unit 33 is placed against the user's skin (skin surface) S and moved while sliding in the X direction, so that the beard (hair) inserted into the blade hole of each outer blade is cut by the outer blade and the inner blade.

[0073] Furthermore, in this embodiment, the electric razor 1 is equipped with a treatment section 34, and by bringing the treatment surface 340 of this treatment section 34 into contact with the skin S, treatment of the skin S can be performed.

[0074] The following describes the specific configuration of the treatment unit 34.

[0075] As shown in Figure 10, the treatment section 34 has a first treatment section 341 and a second treatment section 342. As shown in Figures 13 and 14, when viewed along the Y direction, it has a plate-like shape that is roughly inverted J-shaped overall. When the treatment section 34 is used as an electrode, it is possible to form the treatment section 34 from materials such as metal, conductive resin, or an insulating resin surface coated with metal plating.

[0076] In this embodiment, the first treatment section 341 is positioned on the upper end surface of the head section 30 (the surface on which the skin contact surface 33a is located), and a first treatment surface 3411 is formed on the outer surface of this first treatment section 341. Thus, in this embodiment, the treatment surface 340 is provided with the first treatment surface 3411. The first treatment surface 3411 is positioned to be aligned with the skin contact surface 33a in the X direction (a direction substantially perpendicular to the Y direction), and is provided on the surface including the skin contact surface 33a.

[0077] Furthermore, as shown in Figure 11, the first treatment surface 3411 has an R-shape that curves along the Y direction so as to be convex upwards. In this case, it is preferable that the curvature of the R-shape of the first treatment surface 3411 be approximately the same as the curvature of the R-shape of the net blade 3321. This allows the skin contact surface 33a and the first treatment surface 3411 to be pressed against the skin S with approximately the same pressure when the skin contact surface 33a and the first treatment surface 3411 are brought into contact with the skin S simultaneously. As a result, it is possible to avoid the skin contact surface 33a being pressed too hard against the skin S, and the skin S can be cared for more gently. In addition, it is possible to avoid the first treatment surface 3411 being pressed too hard against the skin S, so the skin contact surface 33a can be firmly attached to the skin S, and the beard can be cut (hair removed) more effectively.

[0078] On the other hand, the second treatment section 342 is positioned on the upper front surface of the head section 30 (the surface that hangs down from the upper end surface of the head section 30 towards the front side of the grip section 111), and a second treatment surface 3421 is formed on the outer surface of this second treatment section 342. Thus, in this embodiment, the treatment surface 340 is equipped with a second treatment surface 3421. Furthermore, the second treatment surface 3421 extends continuously from the first treatment surface 3411 and hangs down along the Z direction from the front end of the first treatment surface 3411. In addition, the second treatment surface 3421 has a larger area than the first treatment surface 3411.

[0079] Furthermore, as shown in Figure 12, the second treatment surface 3421 has a curved shape that curves along the Y direction, convex toward the front in the X direction when viewed from above in the Z direction (viewed from above in the Z direction to below in the Z direction). This allows the second treatment surface 3421 to efficiently fit to, for example, the recessed surface of the face when it is brought into contact with the skin S.

[0080] Furthermore, in this embodiment, as shown in Figures 13 and 14, the boundary portion 343 between the first treatment surface 3411 and the second treatment surface 3421 also has a rounded shape. This ensures that when the skin contact surface 33a and the first treatment surface 3411 are simultaneously in contact with the skin S, a large contact area of ​​the first treatment surface 3411 with respect to the skin S is ensured. Similarly, when the second treatment surface 3421 is in contact with the skin S, a large contact area of ​​the second treatment surface 3421 with respect to the skin S is ensured.

[0081] Furthermore, in this embodiment, the treatment section 34 is held by the retaining wall 312 in a state where it protrudes from the main body 1a (base housing 310 and cover housing 321). This allows the treatment surface 340 of the treatment section 34 to make more reliable contact with the skin S.

[0082] Specifically, as shown in Figures 11 to 13, the treatment surface 340 has a roughly rectangular outline when viewed from the front (from the front in the X direction), with all four sides—the top side 340a, the bottom side 340b, the right side 340c, and the left side 340d—protruding from the main body 1a (base housing 310 and cover housing 321).

[0083] Next, with reference to Figure 15, the functional configuration of the electric shaver 1 will be described. In the following description, the functional configuration of the electric shaver 1 will be described when electrodes are used as the treatment section 34.

[0084] As shown in Figure 15, the electric razor 1 has the following functional configuration: a first temperature sensor 61, a second temperature sensor 62, a drive unit 63, a voltage supply unit 64, a heater 65, and a control unit 66.

[0085] The first temperature sensor 61 detects the temperature of the skin S in contact with the first treatment surface 3411 and outputs temperature data indicating the detected temperature to the control unit 66. The second temperature sensor 62 detects the temperature of the skin S in contact with the second treatment surface 3421 and outputs temperature data indicating the detected temperature to the control unit 66. It is not necessary to provide the first temperature sensor 61 and the second temperature sensor 62 separately; one temperature sensor may serve as both the first temperature sensor 61 and the second temperature sensor 62.

[0086] The drive unit 63 is a device for driving the inner blade, and in this embodiment, it is composed of a drive mechanism 314 having a drive culm 315.

[0087] The voltage supply unit 64 is a voltage source for applying a predetermined voltage to the treatment unit 34. When this voltage supply unit 64 applies a predetermined voltage to the treatment unit 34, a weak current is supplied to the skin S in contact with the treatment unit 34.

[0088] The heater 65 is a heat source for heating the treatment area 34. The control unit 66 controls the drive unit 63 based on the user's operation of the power switch 1111. Specifically, when the user turns on the power of the electric shaver 1 by operating the power switch 1111, the control unit 66 controls the drive unit 63 to drive the drive rod 315. On the other hand, when the user turns off the power of the electric shaver 1 by operating the power switch 1111, the control unit 66 controls the drive unit 63 to stop driving the drive rod 315.

[0089] Furthermore, the control unit 66 controls the voltage supply unit 64 based on the operation of the current selector switch (selector switch 1112) by the user or other party.

[0090] In this embodiment, an electric razor 1 is used to enable more efficient treatment of the skin S.

[0091] Specifically, when performing a treatment on skin S, the treatment surface 340 is covered with a soft sheet 50, and in this state, the soft sheet 50 can be applied to skin S and the treatment on skin S can be performed. In other words, the soft sheet 50 can be held in the electric razor 1 while covering the treatment surface 340.

[0092] In this embodiment, by providing a holding portion 60 on the attachment 40 which is detachably attached to the electric shaver 1, the soft sheet body 50 can be held on the electric shaver 1 in a state that covers the treatment surface 340 when the attachment 40 is attached to the electric shaver 1.

[0093] The specific configuration of attachment 40 will be described below with reference to Figures 16 to 32.

[0094] In this embodiment, the attachment 40 includes an attachment body 41 that is detachably attached to the electric shaver 1, and this attachment body 41 is formed by assembling a plurality of segmented parts. Such an attachment 40 is preferably formed using materials such as acrylonitrile butadiene styrene copolymer resin (ABC resin), polycarbonate resin (PC resin), or polyacetal resin (POM resin), taking into consideration appearance, strength, moldability, etc. At this time, it is more preferable to select a material with excellent chemical resistance, taking into consideration that cosmetics and facial cleansers may adhere to it.

[0095] In this embodiment, as shown in Figures 16 and 17, the attachment body 41 comprises a first segment 42 and a second segment 43, and the attachment body 41 is formed by integrating the first segment 42 and the second segment 43. At this time, as shown in Figures 22 and 23, the second segment 43 is rotatably attached to the first segment 42. By integrating multiple segments in this way, the usability of the attachment 40 can be improved.

[0096] The first segment 42 is a segment that constitutes the rear and side portions of the attachment body 41, and as shown in Figures 16 to 19, it comprises a rear wall 421 which has a shape corresponding to the rear of the head portion 30, and a pair of side walls 422 which are connected to both ends of the rear wall 421 in the Y direction and have a shape corresponding to the side portions of the head portion 30.

[0097] Furthermore, the first divided body 42 is equipped with a mounting wall 423 on which a leaf spring (biasing member) 44 can be placed, and this mounting wall 423 is provided on the upper part of the rear end of the pair of side walls 422. In this embodiment, the mounting wall 423 is connected to each side wall 422 below the upper end of the pair of side walls 422, and as shown in Figures 22 to 25, when the second divided body 43 is assembled to the first divided body 42, the upper part of the mounting wall 423 is covered by the second divided body 43.

[0098] Furthermore, on both sides of the lower end of the rear wall 421 in the Y direction, engaging recesses 4211 are formed so as to be recessed to the rear. As shown in Figure 32, when the attachment body 41 is attached to the head portion 30, a pair of rear engaging protrusions 32112 formed on the rear of the cover housing 321 engage with these pair of engaging recesses 4211. This prevents the attachment 40 from coming off the head portion 30.

[0099] Furthermore, as shown in Figure 17, a spring fixing portion 4231 to which a leaf spring (biasing member) 44 is attached is provided approximately in the center of the mounting wall 423 in the Y direction, and shaft portions 4232 capable of rotatably supporting the second divided body 43 are formed on both sides of this spring fixing portion 4231 in the Y direction.

[0100] On the other hand, the second divided body 43 is a divided body that constitutes the upper and front parts of the attachment body 41, and as shown in Figures 16 to 19, it has a body wall portion 431 that has a shape corresponding to the upper and front parts of the head portion 30.

[0101] Furthermore, on both sides of the lower end of the main body wall portion 431 in the Y direction, engaging recesses 4311 are formed so as to be recessed forward. As shown in Figure 32, when the attachment body 41 is attached to the head portion 30, a pair of front engaging protrusions 32111 formed on the front of the cover housing 321 engage with these pair of engaging recesses 4311. This prevents the attachment 40 from coming off the head portion 30.

[0102] Furthermore, operating parts 4221 are formed at the lower ends of the approximate center in the X direction of the pair of side walls 422 of the first divided body 42. When the attachment body 41 is attached to the head part 30, pressing these operating parts 4221 inward in the Y direction causes the attachment body 41 to elastically deform so that it collapses in the X direction, thereby releasing the engagement between the engagement recess 4211 and the rear engagement projection 32112, and releasing the engagement between the engagement recess 4311 and the front engagement projection 32111. In this way, the attachment 40 can be removed from the head part 30.

[0103] Furthermore, as shown in Figure 19, shaft holding portions 4312 are formed on the upper back side of the main body wall portion 431 of the second divided body 43, corresponding to the shaft portion 4232. By attaching this pair of shaft holding portions 4312 to the shaft portion 4232, the main body wall portion 431 can be rotated around the shaft portion 4232 relative to the first divided body 42. At this time, the main body wall portion 431 is attached to the first divided body 42 so as to cover the opening that opens above and in front of the first divided body 42. Therefore, the second divided body 43 rotates in the front-rear direction relative to the first divided body 42.

[0104] As shown in Figure 17, a pair of positioning walls 4222 are formed on the pair of side walls 422 of the first divided body 42, and a pair of abutment walls 432 are formed on the main body wall 431 of the second divided body 43, which abut against the positioning walls 4222 when the second divided body 43 is rotated in the closing direction, thereby restricting further rotation of the second divided body 43 in the closing direction.

[0105] Furthermore, as shown in Figure 19, the pair of side walls 422 of the first divided body 42 have a locking wall 4223 and a through hole 4224 formed therein. The main body wall 431 of the second divided body 43 has a pair of hook portions 4313 formed therein, which can be inserted from above into each through hole 4224 and locked to the locking wall 4223 when the second divided body 43 is assembled to the first divided body 42. In this way, when the second divided body 43 is rotated in the opening direction, the hook portions 4313 are locked to the locking wall 4223, restricting further rotation of the second divided body 43 in the opening direction.

[0106] As described above, in this embodiment, as shown in Figures 22 and 23, the second divided body 43 is attached to the first divided body 42 so that it can rotate between an open position (a state in which the hook portion 4313 is locked to the locking wall 4223: first position) and a closed position (a state in which the abutting wall portion 432 abuts against the positioning wall portion 4222: second position). At this time, the opening width of the second divided body 43 (the distance the second divided body 43 moves from the closed position to the open position) can be set between 5 mm and 10 mm. In this way, the opening and closing width can be made larger than the thickness of a commercially available flexible sheet body 50 of a common size (width 40 mm to 60 mm, length 60 mm to 80 mm, thickness 2 mm to 6 mm), and when a flexible sheet body 50 of a common size is used, the flexible sheet body 50 can be easily inserted.

[0107] Furthermore, as shown in Figures 16 to 19, each of the pair of abutment walls 432 has a guide projection 4321 that protrudes outward in the Y direction. When the second divided body 43 is rotated, these guide projections 4321 move within the guide grooves 4225 formed in the pair of side walls 422. This allows the second divided body 43 to rotate more smoothly.

[0108] Furthermore, in this embodiment, the second divided body 43 is biased toward the closed position by a leaf spring (biasing member) 44.

[0109] Specifically, as shown in Figures 24 and 25, when the second divided body 43 is assembled to the first divided body 42, the pressing portion 4314 formed on the upper back surface of the main body wall portion 431 is pressed by an elastically deformed leaf spring (biasing member) 44. In this embodiment, the pressing portion 4314 is provided behind the shaft portion 4232, so that the portion of the main body wall portion 431 behind the shaft portion 4232 is pressed upward by the leaf spring (biasing member) 44. In this way, the second divided body 43 is biased toward the closed position by the leaf spring (biasing member) 44. In this embodiment, even in the closed position (when the abutting wall portion 432 abuts against the positioning wall portion 4222), the second divided body 43 is biased toward the closed position by the leaf spring (biasing member) 44. This ensures that even when using flexible sheet bodies 50 of various thicknesses, each flexible sheet body 50 can be more securely held in place by the main body 1a.

[0110] In this case, it is preferable to set the closing load by the leaf spring (biasing member) 44 to 2N to 10N in order to make it easier to open the second divided body 43 while suppressing the shifting of the soft sheet body 50 during use.

[0111] In this embodiment, a holding portion 60 capable of holding the flexible sheet body 50 is provided on the second divided body 43. This holding portion 60 is configured to temporarily hold the flexible sheet body 50.

[0112] Specifically, an insertion opening 4315 is formed in the main body wall portion 431 of the second divided body 43, which is attached to the first divided body 42 so that it can be rotated in the opening and closing direction. Then, as shown in Figures 26 and 27, the soft sheet body 50 can be inserted through this insertion opening 4315, thereby temporarily holding the soft sheet body 50 in place on the second divided body 43 (attachment body 41).

[0113] Thus, in this embodiment, an insertion opening 4315 is provided on the attachment body 41, into which the soft sheet body 50 can be inserted and temporarily held, and functions as a holding part 60 capable of holding the soft sheet body 50.

[0114] Furthermore, in this embodiment, an insertion opening 4315 is formed at the upper part of the second divided body 43 (main body wall portion 431). This makes it easier to insert the flexible sheet body 50 through the insertion opening 4315. It also more reliably prevents the flexible sheet body 50 inserted into the insertion opening 4315 from coming out of the insertion opening 4315.

[0115] Furthermore, an opening 4316 is formed in the main body wall portion 431 of the second divided body 43 in the portion corresponding to the treatment portion 34, allowing the treatment portion 34 to be inserted, and extending through in the X direction. As shown in Figures 30 and 31, when the attachment 40 is attached to the head portion 30, the treatment portion 34 is inserted into the opening 4316, and the treatment surface 340 of the treatment portion 34 is exposed from the opening 4316.

[0116] Using such an attachment 40, the soft sheet body 50 can be held on the electric razor 1 by the following method.

[0117] First, as shown in Figures 26 and 27, the flexible sheet body 50 is inserted through the insertion opening 4315 to temporarily hold the flexible sheet body 50 in place on the second divided body 43 (attachment body 41). At this time, the flexible sheet body 50 is temporarily held on the second divided body 43 (attachment body 41) in a state where the opening 4316 of the second divided body 43 is covered from the back side.

[0118] Next, the attachment 40, with the soft sheet body 50 temporarily held in place, is attached to the head portion 30 of the electric razor 1.

[0119] In this way, the soft sheet body 50 is held in the electric razor 1 while being sandwiched between the attachment 40 and the head part 30.

[0120] At this time, as shown in Figure 29, the entire surface of the skin contact surface 33a of the blade portion 331 is covered by a protective wall 431e provided behind the insertion opening 4315 of the main body wall portion 431 (on the side where the blade portion 331 is located). In other words, when the attachment body 41 is attached to the electric shaver 1 with the soft sheet body 50 inserted through the insertion opening 4315 and temporarily held in place, a protective wall 431e is present between the soft sheet body 50 and the blade portion 331. This makes it possible to more reliably prevent the soft sheet body 50 from coming into contact with the blade portion 331 when the soft sheet body 50 is held and used on the electric shaver 1, thereby suppressing damage to the soft sheet body 50 and corrosion of the blade portion 331.

[0121] In this embodiment, the treatment section 34 is formed to protrude from the main body 1a (base housing 310 and cover housing 321), as described above. Therefore, when attaching the attachment 40 to the head section 30, the second divided body 43 moves in the opening direction, overcoming the treatment section 34, and then moves in the closing direction after overcoming the treatment section 34.

[0122] In this embodiment, when the soft sheet body 50 is held by the attachment 40 and the head portion 30, the soft sheet body 50 is pressed against the upper edge 340a of the treatment surface 340 by the upper regulating wall 431a, which is the peripheral edge of the opening 4316 in the main body wall portion 431; pressed against the lower edge 340b by the lower regulating wall 431b; pressed against the right edge 340c by the right regulating wall 431c; and pressed against the left edge 340d by the left regulating wall 431d.

[0123] In other words, when the attachment body 41 is attached to the electric shaver 1 with the soft sheet body 50 inserted through the insertion opening 4315 and temporarily held in place, all four sides (at least two sides) of the treatment surface 340 are pressed down by the attachment body 41 with the soft sheet body 50 in between. Furthermore, two opposing sides of the treatment surface 340 are pressed down by the attachment body 41 with the soft sheet body 50 in between.

[0124] This prevents the soft sheet body 50 from shifting or bending even when the electric razor 1 is slid back and forth or side to side while performing a treatment on the skin S using the soft sheet body 50.

[0125] As shown in Figures 30 to 32, the attachment 40 can be attached to the head 30 of the electric shaver 1 even when it is not holding the soft sheet body 50. With only the attachment 40 attached to the head 30, the treatment surface 340 of the treatment unit 34 can be applied to the skin S to perform treatment on the skin S.

[0126] By configuring the hair removal device set 100 in this way, it becomes possible to use the electric razor 1 in the first, second, third, and fourth usage modes.

[0127] The following provides an overview of how to use the electric razor 1 in each usage mode.

[0128] First, as shown in Figure 33, the electric shaver 1 can be used in a first usage mode. Specifically, the user turns on the power of the electric shaver 1 by operating the power switch 1111, and the control unit 66 switches to a first usage mode in which beard cutting (hair removal) and skin treatment S are performed simultaneously.

[0129] Then, the user grasps the grip portion 111 with their hand and moves it over the skin S while simultaneously bringing the skin contact surface 33a and the first treatment surface 3411 into contact with the skin S.

[0130] In this way, the blade portion 331 shaves the hairs on the skin S while the first treatment portion 341 performs a treatment on the skin S (for example, applying a weak electric current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

[0131] Furthermore, as shown in Figure 34, the electric razor 1 can also be used in a second usage mode. Specifically, the control unit 66 switches to a second usage mode in which only skin S is treated.

[0132] This operation can be performed, for example, by the user operating the changeover switch 1112 to switch the operating state of the treatment unit 34.

[0133] Then, the user grasps the grip portion 111 with their hand and moves the second treatment surface 3421 of the second treatment portion 342 over the skin S while keeping it in contact with the skin S. At this time, the skin contact surface 33a of the blade portion 331 does not come into contact with the skin S.

[0134] In this way, the second treatment unit 342 performs only skin treatment (for example, applying a weak electric current to skin S, applying heat to skin S, vibrating skin S, etc.) without cutting the beard (removing the hair).

[0135] In this case, if the control unit 66 stops the driving of the drive shaft 315, it becomes possible to suppress unnecessary consumption of the rechargeable battery built into the electric razor 1.

[0136] Furthermore, as shown in Figure 35, the electric shaver 1 can also be used in a third usage mode. This third usage mode, like the second usage mode, does not involve cutting the beard (removing hair), but only involves treating the skin S with the second treatment unit 342 (for example, applying a weak electric current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

[0137] Specifically, the user grasps the grip portion 111 of the electric razor 1, to which the attachment 40 is attached without the soft sheet body 50 being temporarily held, and moves it over the skin S while bringing the second treatment surface 3421 of the second treatment portion 342 exposed from the attachment 40 into contact with the skin S.

[0138] In this way, the second treatment unit 342 performs only skin treatment (for example, applying a weak electric current to skin S, applying heat to skin S, vibrating skin S, etc.) without cutting the beard (removing the hair).

[0139] In this way, by attaching the attachment 40, it becomes possible to more reliably prevent the blade portion 331 from coming into contact with the skin S when the second treatment portion 342 is performing treatment on the skin S. Furthermore, if the blade portion 331 does not come into contact with the skin S when the second treatment portion 342 is performing treatment on the skin S, it becomes possible to prevent the blade portion 331 from coming into contact with the skin S even if the drive rod 315 is unintentionally driven due to a switch malfunction or the like.

[0140] Furthermore, as shown in Figure 36, the electric razor 1 can also be used in a fourth usage mode. This fourth usage mode, like the second usage mode, does not involve cutting the beard (removing hair), but only involves treating the skin S with the second treatment unit 342 (for example, applying a weak electric current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

[0141] Specifically, by attaching the attachment 40, the user grasps the grip portion 111 of the electric razor 1, which holds the soft sheet body 50, and moves it over the skin S while bringing the soft sheet body 50, which covers the second treatment surface 3421 of the second treatment portion 342 that is exposed from the attachment 40, into contact with the skin S.

[0142] In this way, the second treatment unit 342 performs only skin treatment (for example, applying a weak electric current to skin S, applying heat to skin S, vibrating skin S, etc.) without cutting the beard (removing the hair).

[0143] At this time, by applying a soft sheet body 50 impregnated with lotion or cleansing solution to the skin S, it becomes possible to perform treatments on the skin S (for example, applying a weak electric current to the skin S, applying heat to the skin S, or vibrating the skin S) while allowing the lotion or other solution to penetrate the skin S or removing dirt from the skin S.

[0144] Furthermore, by applying the unimpregnated soft sheet 50 to the skin S, it becomes possible to wipe away shaving cream and dirt adhering to the skin S with the soft sheet 50 while performing treatments on the skin S (for example, applying a weak electric current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

[0145] Thus, using the electric razor 1 in this fourth form of use allows for more efficient treatment of the skin S (including the removal of dirt).

[0146] (Embodiment 2) The electric razor (hair removal device) 1 according to this embodiment has basically the same configuration as the electric razor 1 shown in Embodiment 1 above. That is, the electric razor (hair removal device) 1 according to this embodiment also comprises a main body 1a, a blade 331 provided on the main body 1a that is capable of removing hair, and a treatment section 34 provided on the main body 1a separately from the blade 331 that is capable of treating the skin S.

[0147] In this embodiment as well, when performing treatment on the skin S with the treatment unit 34, the soft sheet body 50 held by the electric razor 1 can be applied to the skin S for use.

[0148] In this embodiment, a holding portion 60 is provided on the main body 1a that can hold the soft sheet body 50 while the soft sheet body 50 covers the treatment surface 340 of the treatment portion 34.

[0149] Specifically, a strip-shaped wall portion 32113 extending in the Z direction is integrally formed on the cover housing 321 located on both sides of the treatment section 34 in the Y direction, and an insertion hole 32114 penetrating in the Y direction is formed between the cover housing 321 and the strip-shaped wall portion 32113. By inserting both sides of the soft sheet body 50 into the pair of left and right insertion holes 32114, the electric razor 1 can be held with the soft sheet body 50 and the treatment surface 340 of the treatment section 34 covered by the soft sheet body 50. Thus, in this embodiment, the holding portion 60 is formed by the strip-shaped wall portion 32113 and the insertion hole 32114.

[0150] Furthermore, in this embodiment, as shown in Figure 38, in a side view (viewed along the Y direction), the treatment surface 340 of the treatment section 34 protrudes outward from the band-shaped wall section 32113. This prevents the contact of the treatment surface 340 of the treatment section 34 with the skin S from being obstructed by the band-shaped wall section 32113.

[0151] When using an electric shaver 1 configured in this way, it becomes possible to use it in the first, second, and fourth modes of use as shown in Embodiment 1 above. Specifically, the electric shaver 1 can be used in the first mode of use, in which the blade 331 shaves the beard of the skin S while the first treatment part 341 is applied directly to the skin S to perform treatment on the skin S. It is also possible to use the electric shaver 1 in the second mode of use, in which only skin treatment is performed, by applying the second treatment part 342 directly to the skin S. Furthermore, it is possible to use the electric shaver 1 in the fourth mode of use, in which only skin treatment is performed, by holding the soft sheet body 50 in the electric shaver 1 and applying the soft sheet body 50 covering the second treatment part 342 to the skin S.

[0152] [Effects / Effects] The following describes the characteristic configurations of the hair removal device, attachment, and hair removal device set shown in each of the above embodiments, and the effects obtained thereby.

[0153] The attachment 40 shown in Embodiment 1 above is an attachment 40 that is detachably attached to an electric razor (hair removal device) 1. The electric razor (hair removal device) 1 to which this attachment 40 is detachably attached comprises a main body 1a, a blade 331 provided on the main body 1a that is capable of removing hair, and a treatment section 34 provided on the main body 1a separately from the blade 331 that is capable of performing treatment on the skin S.

[0154] Here, the attachment 40 comprises an attachment body 41 that is detachably attached to the electric razor (hair removal device) 1, and a holding part 60 provided on the attachment body 41.

[0155] Furthermore, the attachment 40 is configured such that, with the attachment body 41 attached to the electric razor (hair removal device) 1, the soft sheet body 50 covers the treatment surface 340 of the treatment area 34, while the holding area 60 holds the soft sheet body 50.

[0156] Furthermore, the hair removal device set 100 shown in Embodiment 1 above comprises the electric razor (hair removal device) 1 and the attachment 40.

[0157] As described above, in Embodiment 1, a holding portion 60 is formed on the attachment 40 which is detachably attached to the electric razor (hair removal device) 1, so that the soft sheet body 50 covering the treatment surface 340 of the treatment section 34 can be held by the holding portion 60.

[0158] This allows the treatment area 34 to be applied to the skin S via the soft sheet body 50, enabling treatment of the skin S. For example, by using a sheet capable of holding liquid as the soft sheet body 50, and holding the soft sheet body 50 impregnated with lotion or cleansing solution in the holding part 60, the soft sheet body 50 can be applied to the skin S. Using the hair removal device set 100 in this manner allows lotion or the like to be efficiently absorbed into the skin S, and dirt on the skin S to be efficiently removed.

[0159] Furthermore, it is also possible to hold the soft sheet body 50, which is not impregnated with liquid, in the holding part 60 and then apply the soft sheet body 50 to the skin S. By using the hair removal device set 100 in this manner, shaving cream and dirt adhering to the skin S can be wiped away with the soft sheet body 50.

[0160] In this way, by forming a holding part 60 on the attachment 40 which is detachably attached to the electric razor (hair removal device) 1, the skin S can be treated more efficiently.

[0161] Furthermore, since the attachment 40 has a holding portion 60, the soft sheet body 50 can be held and used with an existing electric razor (hair removal device) 1 that has both hair removal and treatment functions.

[0162] Furthermore, the attachment body 41 may comprise a first segmented body 42 and a second segmented body 43 formed from a separate component from the first segmented body 42.

[0163] In this way, by constructing the attachment body 41 from multiple segmented parts, even when the treatment section 34 protrudes from the main body 1a to make it easier to apply to the skin S, the attachment body 41 can be attached to the electric shaver (hair removal device) 1 without being obstructed by the treatment section 34. In other words, even when the treatment section 34 protrudes from the main body 1a, the soft sheet body 50 can be more easily held by the electric shaver (hair removal device) 1.

[0164] Furthermore, the second segment 43 may be rotatably attached to the first segment 42.

[0165] By integrating multiple separate components in this way, the usability of attachment 40 can be improved.

[0166] Furthermore, the second segment 43 may be attached to the first segment 42 so as to be able to rotate between an open position (first position) and a closed position (second position). The second segment 43 may also be biased toward the closed position (second position) by a leaf spring (biasing member) 44.

[0167] This allows for more secure retention of each flexible sheet 50 in the main body 1a, even when using flexible sheet 50 of various thicknesses. As a result, various types of flexible sheet 50 with different thicknesses can be used.

[0168] Furthermore, a holding portion 60 may be provided on the second divided body 43, and this holding portion 60 may be configured to temporarily hold the soft sheet body 50.

[0169] This allows the soft sheet 50 to be held in place by the electric shaver (hair removal device) 1 by attaching the attachment 40, which temporarily holds the soft sheet 50, to the main body 1a. As a result, the soft sheet 50 can be held in place by the electric shaver (hair removal device) 1 more easily. In addition, it becomes possible to more reliably suppress the displacement of the soft sheet 50 when it is held in place by the electric shaver (hair removal device) 1. As a result, the soft sheet 50 can be held in a more appropriate position on the electric shaver (hair removal device) 1.

[0170] Alternatively, the holding portion 60 may be an insertion opening 4315 that allows the soft sheet body 50 to be inserted and temporarily held.

[0171] This makes it possible to temporarily hold the flexible sheet 50 in the attachment 40 simply by inserting it into the insertion port 4315, thus making it easier to temporarily hold the flexible sheet 50 in the attachment 40.

[0172] Furthermore, the attachment body 41 may be positioned so that it can be attached to the electric razor (hair removal device) 1 by moving it from above to below, and the insertion opening 4315 may be formed on the upper part of the second divided body 43.

[0173] This makes it easier to insert the flexible sheet body 50 through the insertion opening 4315, and also makes it more reliable to prevent the flexible sheet body 50 from coming out of the insertion opening 4315 once it has been inserted.

[0174] Furthermore, when the attachment body 41 is attached to the electric razor (hair removal device) 1 with the soft sheet body 50 inserted through the insertion opening 4315 and temporarily held in place, the attachment body 41 may also be provided with a protective wall 431e that exists between the soft sheet body 50 and the blade portion 331.

[0175] This makes it possible to more reliably prevent the soft sheet 50 from coming into contact with the blade 331 when it is held and used in the electric razor (hair removal device) 1. As a result, it becomes possible to more reliably prevent the soft sheet 50 from tearing due to contact with the blade 331. In addition, it becomes possible to more reliably prevent the blade 331 from corroding due to the liquid impregnated in the soft sheet 50, thus preventing the deterioration of the blade 331 from accelerating.

[0176] Furthermore, when the attachment body 41 is attached to the electric razor (hair removal device) 1, the entire surface of the skin contact surface 33a of the blade portion 331 may be covered by the protective wall 431e.

[0177] This allows the blade portion 331 to be protected by the protective wall 431e when the attachment body 41 is attached to the electric shaver (hair removal device) 1. Therefore, the attachment 40 can be used as a blade protective cap when the electric shaver (hair removal device) 1 is not in use.

[0178] Furthermore, when the attachment body 41 is attached to the electric razor (hair removal device) 1 with the soft sheet body 50 inserted through the insertion opening 4315 and temporarily held in place, at least two sides of the treatment surface 340 may be pressed down by the attachment body 41 with the soft sheet body 50 in between.

[0179] This makes it possible to more reliably prevent the soft sheet body 50 from shifting position when performing a treatment on the skin S using the soft sheet body 50.

[0180] Furthermore, two opposing sides of the treatment surface 340 may be pressed down by the attachment body 41 with the soft sheet body 50 interposed between them.

[0181] This prevents the soft sheet body 50 from shifting or bending when the electric razor (hair removal device) 1 is slid in a direction opposite to the two sides held down by the attachment body 41 during skin treatment using the soft sheet body 50. As a result, skin treatment can be performed more effectively.

[0182] Furthermore, the electric razor (hair removal device) 1 shown in Embodiment 2 above comprises a main body 1a, a blade 331 provided on the main body 1a that is capable of removing hair, a treatment section 34 provided on the main body 1a separately from the blade 331 that is capable of performing treatment on the skin S, and a holding section 60 provided on the main body 1a that is capable of holding the soft sheet 50 in a state where the soft sheet 50 covers the treatment surface 340 of the treatment section 34.

[0183] This also allows for more efficient treatment of the skin S. Furthermore, by providing a holding part 60 on the main body 1a, the soft sheet body 50 can be held by the main body 1a with a simpler configuration.

[0184] Alternatively, the holding portion 60 may be integrally formed with the main body portion 1a.

[0185] This prevents the loss of the retaining part 60, as would occur if the retaining part 60 were detachably attached to the main body part 1a.

[0186] [others] The contents of the hair removal device described herein have been explained above, but it will be obvious to those skilled in the art that the device is not limited to these descriptions and that various modifications and improvements are possible.

[0187] For example, this disclosure can be applied to embodiments in which the configurations shown in each of the above embodiments are modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in each of the above embodiments to create new embodiments.

[0188] Furthermore, although the above embodiments illustrate an electric razor 1 having a grip portion 111 and a head portion 30, it is also possible to apply this disclosure to an electric razor that does not have a head portion.

[0189] Furthermore, the configuration for holding the soft sheet body 50 in the main body 1a is not limited to the configurations shown in the above embodiments, and various configurations are possible.

[0190] For example, the soft sheet body 50 can be held in place by attaching the first divided body 42 to the main body 1a in a detachable manner, while simultaneously attaching the second divided body 43 to the main body 1a in a detachable manner.

[0191] Alternatively, the flexible sheet body 50 can be temporarily held in place by sandwiching it between the first divided body 42 and the second divided body 43, and in this state, at least one of the first divided body 42 and the second divided body 43 can be attached to the main body 1a to hold the flexible sheet body 50 in place.

[0192] Furthermore, while the above embodiments exemplified an electric razor 1 for cutting beards as a hair removal device, the present disclosure can be applied to various types of hair removal devices, not limited to the electric razor 1. For example, the present disclosure can be applied to a trimmer (electric hair cutting device) for cutting body hair or hair of a person or animal, or to a hair removal device for removing hair from a person or animal.

[0193] Furthermore, the head unit, attachments, and other detailed specifications (shape, size, layout, etc.) can be modified as needed. [Industrial applicability]

[0194] As described above, the hair removal device, attachment, and hair removal device set disclosed herein can perform skin treatments more efficiently and can therefore be applied not only to facial hair but also to the treatment of various other body hairs. [Explanation of Symbols]
