Detailed Description

Hereinafter, embodiments will be described in detail with reference to the drawings. However, a detailed description thereof may be omitted. For example, detailed descriptions of well-known matters or repeated descriptions of substantially the same structure may be omitted.

Furthermore, the figures and the following description are provided for a full understanding of the present disclosure by those skilled in the art, and are not intended to limit the subject matter recited in the claims using them.

In the following embodiments, an electric razor for cutting the beard (hair) of a user or the like is exemplified as the hair removing device.

In the following embodiments, a direction in which a plurality of blade assemblies are arranged is described as an X direction (i.e., a 1 st direction: a front-rear direction: a shaving direction), and a direction in which each blade assembly extends is described as a Y direction (i.e., a 2 nd direction: a left-right direction: a width direction).

The vertical direction in which the head (i.e., an element of the electric razor) is disposed with the skin contact surface facing upward will be described as the Z direction (i.e., the vertical direction of the head). In the present embodiment, the skin contact surface of the blade unit is constituted by the surfaces (i.e., the outer surfaces) of the outer blades of the plurality of blade assemblies, and the entirety thereof is a surface that can be approximated by a curved surface that protrudes outward. Therefore, in the following embodiments and modifications thereof, the state in which the point of the curved surface, which is close to the skin contact surface of the blade unit, that protrudes furthest outward is the uppermost point, and the tangential plane at the point of the curved surface, which is close to the skin contact surface of the blade unit, that protrudes furthest outward is the horizontal plane is set to the state in which the head (i.e., one element of the electric razor) is disposed with the skin contact surface facing upward.

In the following embodiments, a description will be given of a case where a side facing a user in a state where the user holds the handle portion of the electric razor 1 is defined as a front side (i.e., a front side in the X direction) of the electric razor in normal use.

(embodiment 1)

First, a brief description will be given of the structure of the hair removal device kit 100 according to embodiment 1 with reference to fig. 1 to 3. Fig. 1 is a perspective view showing a hair removal device set 100 according to embodiment 1. Fig. 2 is an exploded perspective view showing the hair removal device package 100 according to embodiment 1. Fig. 3 is a perspective view showing a state in which the soft sheet body 50 is held by the hair removing device set 100 according to embodiment 1.

As shown in fig. 1 and 2, the hair removal device kit 100 of the present embodiment includes: an electric razor 1 (i.e., an example of a hair removing device) having a blade portion 331 provided in a main body portion 1a to remove hair; and a fitting 40 detachably attached to the electric razor 1.

The main body 1a of the electric razor 1 is provided with an application portion 34 capable of performing an application of the skin S independently of the blade portion 331.

In this way, the electric razor 1 provided in the hair removal device set 100 has a hair removal function for cutting the beard of the skin S by the blade portion 331 and an application function for applying the skin S by bringing the application surface 340 of the application portion 34 into contact with the skin S. Cutting the beard is one example of removing hair.

Examples of the application of the skin S by the application unit 34 include applying a weak current to the skin S, applying heat to the skin S, and vibrating the skin S. In this case, the operation unit 34 may have a plurality of operation functions.

In the present embodiment, the attachment 40 is detachably attached to the electric razor 1 having such a function.

As shown in fig. 3, the fitting 40 includes: a fitting main body 41 detachably attached to the electric razor 1 (i.e., an example of a hair removing device); and a holding portion 60 provided to the fitting body 41.

As shown in fig. 1 and 3, the attachment 40 is configured such that, when the attachment main body 41 is attached to the electric razor 1 (i.e., an example of a hair removal device), the soft sheet body 50 covers the application surface 340 of the application portion 34, and the holding portion 60 can hold the soft sheet body 50. As the soft sheet 50, for example, a known commercially available product such as a cotton sheet, a sponge sheet, or a soft cloth can be used. Further, a member dedicated to the soft sheet 50 to be held by the holding portion 60 may be prepared.

Further, when the skin S is applied by the application unit 34, the soft sheet body 50 held by the electric razor 1 can be used in contact with the skin S.

Next, a schematic configuration of the electric razor 1 according to embodiment 1 will be described with reference to fig. 4 to 7. Fig. 4 is a front view showing an electric razor 1 as a hair removing device according to embodiment 1. Fig. 5 is a side view showing the electric razor 1 of embodiment 1. Fig. 6 is a rear view showing the electric razor 1 of embodiment 1. Fig. 7 is a perspective view showing the electric razor 1 according to embodiment 1 in an exploded manner.

As shown in fig. 4 to 7, the electric razor 1 (i.e., an example of a hair removing device) of the present embodiment includes: a razor body 10; a head 30 supported by the razor main body 10; and a coupling mechanism 20 for coupling the head 30 and the razor main body 10. The head 30 is provided with a blade 331 capable of cutting a beard (i.e., an example of hair) and an application unit 34 capable of applying the skin S. As described above, in the present embodiment, the main body portion 1a of the electric razor 1 is formed of the razor main body 10, the coupling mechanism 20, and the head portion 30 (except for the blade portion 331 and the application portion 34).

The razor main body 10 includes a main body case 11, and the main body case 11 has a vertically elongated tubular shape with substantially the same diameter. The cylindrical portion of the main body case 11 having a substantially uniform diameter serves as a grip portion 111 that can be held by a user's hand when the electric razor 1 is used.

The main body case 11 can be formed by joining a plurality of divided bodies by using screws or the like, and a cavity is formed in the main body case 11. Various electrical components such as a rechargeable battery are housed in a cavity formed in the main body case 11. The plurality of segments can be formed using a material such as synthetic resin or metal.

As shown in fig. 4, a push-type power switch 1111 for operating the electric razor 1 is formed in the handle portion 111 of the main body case 11. The power supply of the electric razor 1 is turned on/off by the power switch 1111.

In the present embodiment, a changeover switch 1112 for switching the operation state of the operation unit 34 is formed in the handle 111. When the operation unit 34 is an electrode that applies a weak current to the skin S, the change-over switch 1112 can be a current change-over switch that changes over between, for example, three steps ("strong", "weak", "off"). Further, a temperature change switch 1113 for changing the temperature condition of the operation unit 34 is formed in the handle 111. The temperature change switch 1113 can be a switch for changing the temperature of the application unit 34 between, for example, three steps ("high", "low", "off").

In the present embodiment, the push-type switch is exemplified as the various switches, but these switches may be constituted by other switches such as a slide-type switch.

In addition, in the present embodiment, the power switch 1111 is formed on the front surface of the main body casing 11 (more specifically, the handle portion 111), that is, the front surface (i.e., the front surface) of the electric razor 1. In this way, the user or the like can operate the power switch 1111 with the thumb of the user or the like while holding the handle portion 111 of the electric razor 1.

Likewise, the change-over switch 1112 and the temperature change-over switch 1113 are also formed on the front surface of the main body housing 11 (more specifically, the handle portion 111), that is, the front surface (i.e., the front surface) of the electric razor 1. The 3 switches are arranged in the longitudinal direction of the main body case 11 (more specifically, the handle 111).

In addition, when the operation unit 34 is an electrode, it is preferable that a counter electrode unit 1114 made of, for example, metal is disposed on the back surface of the handle unit 111 as shown in fig. 6. When such a counter electrode portion 1114 is disposed, a closed circuit through the body of the user can be formed between the electrode serving as the operation portion 34 and the counter electrode portion 1114 when the electric razor 1 is used. When the electric razor 1 is used in a state where a closed circuit is formed, a weak current easily flows through the body of the user, and a voltage having the same potential (i.e., a voltage having a substantially constant value) can be always applied to the skin S to be dehaired.

When such a counter electrode portion 1114 is provided in the handle portion 111, it is preferable to use a long counter electrode portion 1114 extending in the longitudinal direction of the handle portion 111. In this way, the user can more reliably contact the palm or fingers of the user with the counter electrode portion 1114 when holding the handle portion 111 by hand. As a result, the user can bring the palm or finger of the user into contact with the counter electrode portion 1114 by merely holding the handle portion 111 with his or her hand. That is, the user can grasp the grip portion 111 to improve a weak electro-stimulation effect. The material of the counter electrode 1114 is not limited to metal, and may be, for example, a conductive resin, a material having a metal plating layer on the surface of an insulating resin, or the like.

A coupling mechanism 20 for supporting the head 30 to the razor main body 10 is fixed to the upper portion of the main body case 11. In the present embodiment, the coupling mechanism 20 has a tubular shape that expands in diameter with the upward direction, and the trimming unit 21 is provided at the rear of the coupling mechanism 20. The trimming unit may be provided not to the coupling mechanism 20 but to the head 30 or the razor main body 10. In addition, the electric razor 1 may be provided without a trimming unit.

Then, in a state where the coupling mechanism 20 is fixed to the main body case 11, the head 30 is supported by the coupling mechanism 20, and the head 30 is supported by the razor main body 10. At this time, the head 30 is supported by the razor body 10 so as to be inclined upward and forward in a state where the extending direction of the razor body 10 is substantially aligned with the vertical direction. In this way, when the extending direction of the razor main body 10 is aligned with the up-down direction, the portion of the blade portion 331 that contacts the skin S (more specifically, the skin contact surface 33a described later) is inclined forward and downward with respect to the horizontal plane, and when the electric razor 1 is used by holding the handle portion 111, the skin contact surface 33a is easily brought into contact with the skin S of the user.

Further, the head 30 may not be inclined with respect to the razor main body 10.

The head 30 may be supported by the razor body 10 (more specifically, the coupling mechanism 20) so as to be movable (for example, linearly reciprocate, swing, etc.) relative to the razor body 10 in at least one direction.

In the present embodiment, as shown in fig. 7, the head 30 is coupled to the coupling mechanism 20 by the shaft 22 extending in the front-rear direction of the head 30 in a state where the head 30 is disposed with the skin contact surface 33a facing upward. That is, the head 30 is supported by the razor body 10 so as to be swingable about the shaft 22 with respect to the razor body 10 in the width direction of the head 30. In this way, when the electric razor 1 is used, the adhesion between the blade portion 331 and the skin S can be further improved, and the beard (i.e., an example of hair) can be shaved more efficiently. In this specification, "shaving" is an example of hair removal.

The head 30 may be configured to be movable relative to the razor body 10 in 1 direction or in two or more directions other than the width direction of the head 30, or the head 30 may not be movable relative to the razor body 10.

Next, a specific configuration of the head 30 will be described with reference to fig. 8 to 14. Fig. 8 is a view showing the electric razor 1 of embodiment 1, and is a perspective view showing the head 30 partially exploded. Fig. 9 is a perspective view showing the hood 32 of the electric razor 1 according to embodiment 1 in an exploded manner. Fig. 10 is a perspective view showing a head 30 of the electric razor 1 according to embodiment 1. Fig. 11 is a front view showing a head 30 of the electric razor 1 according to embodiment 1. Fig. 12 is a plan view showing a head 30 of the electric razor 1 according to embodiment 1. Fig. 13 is a side view showing a head 30 of the electric razor 1 according to embodiment 1. Fig. 14 is a cross-sectional view showing a head 30 of the electric razor 1 according to embodiment 1.

In the present embodiment, as shown in fig. 8, the head 30 is configured to be divided into a plurality of members, and includes a head base 31 attached to the coupling mechanism 20 and a head cover 32 detachably attached to the head base 31.

In the present embodiment, release buttons 311 are provided at both left and right ends of the head base 31 so as to be able to protrude and retract, and the attachment of the head cover portion 32 to the head base 31 can be released by retracting the release buttons 311 to the inside.

The head base 31 includes a base housing 310, and a holding wall 312 for holding the operation unit 34 is attached to the front side of the base housing 310 by a screw 313.

As shown in fig. 14, a space is formed inside the base housing 310, and a drive mechanism 314 is housed in the space. In the present embodiment, the driving mechanism 314 includes a plurality of driving rods 315 (see fig. 8), and the driving rods 315 are housed in the head base 31 in a state protruding upward from the head base 31. As such a driving mechanism 314, for example, a conventionally known mechanism such as a vibration type linear actuator, a driving mechanism including a rotary motor and a conversion mechanism for converting rotary motion into reciprocating linear motion, and the like can be used.

On the other hand, as shown in fig. 9, the hood 32 includes a hood case 321, and the blade unit 33 is attached to the hood case 321.

Next, a specific configuration of the blade unit 33 will be described.

The blade unit 33 includes 3 blade units and an outer blade housing 334, and as shown in fig. 12, the 3 blade units are arranged in the X direction in such a manner that the longitudinal direction coincides with the Y direction.

As described above, in the present embodiment, each of the blade units has a predetermined length and width, and the blade units are arranged in a state in which the longitudinal direction is substantially aligned with the Y direction (i.e., the 2 nd direction: the left-right direction) of the electric razor 1 and the width direction is substantially aligned with the X direction (i.e., the 1 st direction: the front-rear direction: the shaving direction) of the electric razor 1.

In the present embodiment, 3 blade assemblies are composed of two net blade assemblies 332 and 1 slit blade assembly 333.

Further, the net blade assembly 332 is a blade assembly having mainly the function of cutting beard in a lodged state (i.e., one example of body hair) and beard in a short and standing state (i.e., one example of body hair). Also, the slit blade assembly 333 is a blade assembly having mainly a function of cutting out an elongated beard (i.e., one example of body hair).

In the present embodiment, 1 slit blade assembly 333 is disposed at the center in the X direction, and two net blade assemblies 332 are disposed at both sides of the slit blade assembly 333, respectively.

As shown in fig. 8, the net blade assembly 332 includes a net blade 3321 and a net inner blade 3322. In the present embodiment, the mesh blade 3321 is curved in an inverted U shape so as to protrude upward in a side view (i.e., a state viewed along the Y direction).

Further, the mesh blade 3321 is formed to be slightly curved in the Y direction (i.e., the outer blade length direction) in such a manner as to protrude upward when viewed from the front (i.e., a state viewed in the X direction). A plurality of circular blade holes (not shown) are formed in the mesh blade 3321. The net blade 3321 may be curved so as not to protrude upward when viewed from the front. For example, it can be set as: in a state in which the mesh blade 3321 is viewed from the front (i.e., a state viewed along the X direction), the top of the mesh blade 3321 is a straight line extending in the Y direction (i.e., the outer blade length direction).

The net-shaped inner blade 3322 has an inverted U-shape similar to the curved shape of the net-shaped blade 3321, and is disposed inside the net-shaped blade 3321 (i.e., on the lower side of the net-shaped blade 3321, on the opposite side of the net-shaped blade 3321 from the side contacting the skin S). The net-shaped inside blade 3322 is detachably mounted to 1 driving lever 315 among the plurality of driving levers 315. When the drive lever 315 is driven by turning on the power supply of the electric razor 1 in a state where the mesh inner blade 3322 is mounted on the drive lever 315 and disposed inside the mesh blade 3321, the mesh inner blade 3322 is relatively displaced (i.e., relatively moved: reciprocated in the Y direction) with respect to the mesh blade 3321 while being in sliding contact with the inner surface of the mesh blade 3321.

As shown in fig. 14, the slit blade assembly 333 is provided with a slit outer blade 3331 and a slit inner blade 3332. In the present embodiment, the slit outer blade 3331 is formed to be bent in an inverted U shape so as to protrude upward in a side view (i.e., a state viewed along the Y direction). The slit outer blade 3331 is formed such that the top surface is substantially flat in a side view (i.e., in a state of being viewed along the Y direction).

Further, the slit outer blade 3331 is formed to be slightly curved in the Y direction (i.e., the outer blade length direction) so as to protrude upward when viewed from the front (i.e., a state viewed in the X direction). A plurality of slit-shaped blade holes extending in the X direction are formed in the slit outer blade 3331 so as to be spaced apart in the Y direction. The slit outer blade 3331 may be curved so as not to protrude upward when viewed from the front. For example, it can be set as: in a state in which the slit outer blade 3331 is viewed from the front (i.e., a state viewed along the X direction), the top of the slit outer blade 3331 is a straight line extending in the Y direction (i.e., the outer blade length direction). That is, the slit outer blade 3331 may be formed such that the top surface of the slit outer blade 3331 is a flat surface (i.e., a flat surface).

The slit inner blade 3332 has an inverted U-shape similar to the bent shape of the slit outer blade 3331, and is disposed inside the slit outer blade 3331 (i.e., on the lower side of the slit outer blade 3331, opposite to the side of the slit outer blade 3331 that contacts the skin S). The in-slot blade 3332 is removably mounted to 1 of the plurality of drive rods 315 (i.e., a separate drive rod 315 relative to the drive rod to which the net-shaped in-blade 3322 is mounted). When the power of the electric razor 1 is turned on and the drive lever 315 is driven in a state in which the in-slit blade 3332 is attached to the drive lever 315 and disposed inside the out-slit blade 3331, the in-slit blade 3332 is relatively displaced (i.e., relatively moved: reciprocated in the Y direction) with respect to the out-slit blade 3331 while being in sliding contact with the inner surface of the out-slit blade 3331.

As described above, the electric razor 1 of the present embodiment is an electric razor having a form of a reciprocating electric razor in which the net-shaped inner blade 3322 and the slit inner blade 3332 are reciprocated with respect to the net-shaped blade 3321 and the slit outer blade 3331. Thus, in the present embodiment, the blade portion 331 is provided with 3 outer blades (i.e., two net-shaped blades 3321 and 1 slit outer blade 3331) and 3 inner blades (i.e., two net-shaped inner blades 3322 and 1 slit inner blade 3332).

In the present embodiment, the members of the 3 blade assemblies other than the two net-shaped inner blades 3322 are attached to the substantially frame-shaped outer blade housing 334. In this case, each member may be detachably attached to the outer blade case 334, or may be attached to the outer blade case 334 in a state of being unable to be detached.

In the present embodiment, the two net blade assemblies 332 and the 1 slit blade assemblies 333 are attached to the outer blade case 334 in a state capable of floating in the Z direction (i.e., the up-down direction). Thus, when the cover housing 321 (i.e., an element of the head cover portion 32) to which the outer blade cartridge 330 is attached to the head base portion 31, each blade assembly is independently floated from the head portion 30. Further, the two net blade assemblies 332 and 1 or more of the slit blade assemblies 333 may be configured not to float in the Z direction (i.e., up-down direction).

In the present embodiment, as shown in fig. 8, the two net blades 3321 can be attached to the outer blade case 334 without disposing the net inner blade 3322 inside. On the other hand, the 1 slit outer blade 3331 is attached to the outer blade case 334 in a state in which the slit inner blade 3332 is disposed inside. As described above, in the present embodiment, the outer blade cartridge 330 is formed by attaching the two net blades 3321 and the 1 slit blade assemblies 333 to the outer blade case 334. The outer blade case 330 is detachably attached to the cover case 321.

Specifically, as shown in fig. 9, the cover case 321 includes a substantially tubular peripheral wall portion 3211 formed with an upper opening 321a and a lower opening 321b, and the outer blade cartridges 330 are attached to the cover case 321 by inserting the outer blade cartridges 330, each of which faces upward, from the lower opening 321b side of the cover case 321. At this time, the outer blade cartridges 330 are attached to the cover housing 321 in a state in which the surfaces of the outer blades are exposed from the upper side openings 321a of the cover housing 321. Therefore, in the present embodiment, the portion of the surface of each outer blade exposed from the upper opening 321a of the cover housing 321 becomes the portion exposed to the outside of the blade portion 331. That is, a portion of the surface of each outer blade exposed from the upper side opening 321a of the cover housing 321 becomes a skin contact surface 33a that contacts the skin S (i.e., skin surface) of the user.

Release buttons 3341 are formed at both left and right ends of the outer blade housing 334, and the attachment of the cover case 321 to the outer blade cartridge 330 can be released by operating the release buttons 3341.

In the present embodiment, the roller 35 is rotatably supported by the cover case 321. The roller 35 is formed in a long shape along the Y direction, and is disposed between the mesh blade 3321 located on the front side and the application portion 34.

As shown in fig. 14, the roller 35 is supported by the cover case 321 so as to protrude upward from the skin contact surface 33a and the upper surface of the applicator 34. When the user holds the handle 111 by hand and presses the skin contact surface 33a against the skin S, the roller 35 receives the force to the greatest extent that the head 30 is pressed against the skin S. In this way, the frictional resistance can be reduced by the rotating roller 35, and the skin contact surface 33a can be moved on the skin S so as to slide with less friction while reliably pressing the skin contact surface 33a against the skin S.

As described above, in the present embodiment, the cover case 321 to which the outer blade cartridge 330 is attached to the head base 31 in a state where the two net-shaped inner blades 3322 are attached to the driving lever 315 protruding upward from the head base 31. When the cover case 321 to which the outer blade cartridge 330 is attached to the head base 31 in a state where the two net-shaped inner blades 3322 are attached to the drive lever 315, the two net-shaped inner blades 3322 are disposed inside the corresponding net-shaped blades 3321.

Thus, when the electric razor 1 is powered on, each inner blade is relatively displaced (i.e., relatively moved: reciprocated in the Y direction) with respect to the corresponding outer blade.

Then, when the electric razor 1 is powered on and each inner blade is relatively displaced with respect to the corresponding outer blade, the skin contact surface 33a of the blade unit 33 is brought into contact with the skin S (i.e., the skin surface) of the user and slidingly moved in the X direction, so that the beard (i.e., one example of hair) inserted into the blade hole of each outer blade is cut off by the outer blade and the inner blade.

In the present embodiment, the electric razor 1 includes the application unit 34, and the application of the skin S can be performed by bringing the application surface 340 of the application unit 34 into contact with the skin S.

The specific configuration of the applicator 34 will be described below.

As shown in fig. 10, the applicator 34 has a 1 st applicator 341 and a 2 nd applicator 342. As shown in fig. 13 and 14, the applicator 34 has a substantially inverted J-shaped plate shape as a whole when viewed along the Y direction. In the case where the operation portion 34 is an electrode, the operation portion 34 may be formed of, for example, a metal, a conductive resin, a material in which a metal plating layer is coated on the surface of an insulating resin, or the like.

In the present embodiment, the 1 st operation portion 341 is disposed on the upper end surface of the head 30 (i.e., the surface on which the skin contact surface 33a is disposed), and the 1 st operation surface 3411 is formed on the outer surface of the 1 st operation portion 341. As described above, in the present embodiment, the work surface 340 includes the 1 st work surface 3411. The 1 st operation surface 3411 is disposed so as to be aligned with the skin contact surface 33a in the X direction (i.e., a direction substantially perpendicular to the Y direction), and is provided on a surface including the skin contact surface 33 a.

As shown in fig. 10, the 1 st working surface 3411 has a rounded curve shape curved in the Y direction so as to protrude upward. In this case, the curvature of the rounded shape of the 1 st working surface 3411 is preferably substantially the same as the curvature of the rounded shape of the mesh blade 3321. In this way, when the skin contact surface 33a and the 1 st operation surface 3411 are brought into contact with the skin S at the same time, the skin contact surface 33a and the 1 st operation surface 3411 can be pressed against the skin S with substantially the same pressure. As a result, only the skin contact surface 33a can be prevented from being strongly pressed against the skin S, and care of the skin S can be performed softly. Further, since only the 1 st operation surface 3411 is strongly pressed against the skin S, the skin contact surface 33a can be reliably brought into close contact with the skin S, and the beard can be cut more effectively (i.e., an example of hair removal).

On the other hand, the 2 nd working portion 342 is disposed on the upper front surface of the head 30 (i.e., a surface hanging down from the upper end surface of the head 30 toward the front surface side of the handle portion 111), and the 2 nd working surface 3421 is formed on the outer surface of the 2 nd working portion 342. As described above, in the present embodiment, the working surface 340 includes the 2 nd working surface 3421. Further, the 2 nd working surface 3421 extends continuously from the 1 st working surface 3411, and hangs down in the Z direction from the tip of the 1 st working surface 3411. In addition, the 2 nd working surface 3421 has an area larger than that of the 1 st working surface 3411.

As shown in fig. 12, the 2 nd working surface 3421 has a rounded curve shape curved along the Y direction so as to protrude forward in the X direction in a plan view (i.e., a state in which the lower side in the Z direction is viewed from the upper side in the Z direction). In this way, when the 2 nd surgical surface 3421 is brought into contact with the skin S, the 2 nd surgical surface 3421 can be efficiently bonded to a recessed surface such as a face.

In the present embodiment, as shown in fig. 13 and 14, the boundary 343 between the 1 st working surface 3411 and the 2 nd working surface 3421 is also in a rounded curve shape. In this way, when the skin contact surface 33a and the 1 st application surface 3411 are simultaneously brought into contact with the skin S, a large contact area between the 1 st application surface 3411 and the skin S can be ensured. In addition, when the 2 nd surgical surface 3421 is brought into contact with the skin S, the contact area of the 2 nd surgical surface 3421 with the skin S can be ensured to be large.

In the present embodiment, the application portion 34 is held by the holding wall 312 in a state protruding from the main body portion 1a (more specifically, the base housing 310 and the cover housing 321). In this way, the application surface 340 of the application portion 34 can be more reliably brought into contact with the skin S.

Specifically, as shown in fig. 11 to 13, the application surface 340 has a substantially rectangular outline when viewed from the front (i.e., when viewed from the front in the X direction), and all of the 4 sides, that is, the upper side 340a, the lower side 340b, the right side 340c, and the left side 340d, protrude from the main body portion 1a (more specifically, the base housing 310 and the cover housing 321).

Next, the functional structure of the electric razor 1 will be described with reference to fig. 15. In the following, the functional configuration of the electric razor 1 in the case where an electrode is used as the application unit 34 will be described. Fig. 15 is a block diagram showing a functional configuration of the electric razor 1 according to embodiment 1.

As shown in fig. 15, the electric razor 1 includes a 1 st temperature sensor 61, a 2 nd temperature sensor 62, a driving unit 63, a voltage supply unit 64, a heater 65, and a control unit 66 as functional configurations.

The 1 st temperature sensor 61 detects the temperature of the skin S in contact with the 1 st application surface 3411, and outputs temperature data indicating the detected temperature to the control unit 66. The 2 nd temperature sensor 62 detects the temperature of the skin S in contact with the 2 nd application surface 3421, and outputs temperature data indicating the detected temperature to the control unit 66. Further, the 1 st temperature sensor 61 and the 2 nd temperature sensor 62 may be used as the 1 st temperature sensor 61 and the 2 nd temperature sensor 62 without providing the 1 st temperature sensor 61 and the 2 nd temperature sensor 62, respectively.

The driving unit 63 is a device for driving the inner blade, and in the present embodiment, is constituted by a driving mechanism 314 having a driving lever 315.

The voltage supply unit 64 is a voltage supply source for applying a predetermined voltage to the application unit 34, and the weak current is supplied to the skin S in contact with the Shi Shubu by applying the predetermined voltage to the application unit 34 through the voltage supply unit 64.

The heater 65 is a heat source for heating the application portion 34. The control unit 66 is configured to control the driving unit 63 based on the user's operation of the power switch 1111. Specifically, when the user or the like operates the power switch 1111 to turn on the power of the electric razor 1, the control unit 66 controls the driving unit 63 to drive the driving lever 315. On the other hand, when the user or the like operates the power switch 1111 to turn off the power of the electric razor 1, the control unit 66 controls the driving unit 63 to stop the driving of the driving lever 315.

The control unit 66 controls the voltage supply unit 64 based on an operation of a current changeover switch (i.e., the changeover switch 1112) by a user or the like.

In the present embodiment, the electric razor 1 can be used to perform the skin S more efficiently.

Specifically, when performing the skin S, the operation surface 340 is covered with the soft sheet body 50, and in this state, the soft sheet body 50 can be brought into contact with the skin S to perform the skin S operation. That is, the soft sheet 50 can be held by the electric razor 1 in a state of covering the operation surface 340.

In the present embodiment, the holding portion 60 is provided in the attachment 40 that is detachably attached to the electric razor 1, so that the soft sheet body 50 can be held in the electric razor 1 in a state of covering the operation surface 340 when the attachment 40 is attached to the electric razor 1.

The specific structure of the fitting 40 will be described below with reference to fig. 16 to 32.

Fig. 31 is a side view showing a state in which only the attachment 40 is attached to the head 30 of the electric razor 1 of embodiment 1. Fig. 32 is a cross-sectional view showing a state in which only the attachment 40 is attached to the head 30 of the electric razor 1 of embodiment 1.

In the present embodiment, the accessory 40 includes an accessory main body 41 that is detachably attached to the electric razor 1, and the accessory main body 41 is formed by assembling a plurality of divided bodies. Such a fitting 40 is preferably formed using a material such as an acrylonitrile-butadiene-styrene copolymer resin (hereinafter, referred to as "ABC resin"), a polycarbonate resin (hereinafter, referred to as "PC resin"), a polyoxymethylene resin (hereinafter, referred to as "POM resin") or the like in consideration of appearance, strength, formability, or the like. In this case, it is more preferable to select a material having excellent chemical resistance in consideration of the adhesion of a cosmetic, a face washing agent, or the like.

In the present embodiment, as shown in fig. 16 and 17, the fitting body 41 includes a 1 st divided body 42 and a 2 nd divided body 43, and the fitting body 41 is formed by integrating the 1 st divided body 42 and the 2 nd divided body 43. At this time, as shown in fig. 22 and 23, the 2 nd division body 43 is rotatably attached to the 1 st division body 42. In this way, by integrating the plurality of divided bodies, the fitting 40 can be used more conveniently.

The 1 st divided body 42 is a divided body constituting the rear and side portions of the fitting main body 41, and includes, as shown in fig. 16 to 19: a rear wall 421 having a shape corresponding to the rear portion of the head 30; and a pair of side walls 422 provided continuously with both ends of the rear wall 421 in the Y direction, and having a shape corresponding to the side portions of the head 30.

The 1 st divided body 42 includes a mounting wall 423 on which the leaf spring 44 (i.e., an example of the urging member) can be mounted, and the mounting wall 423 is provided at an upper portion of the rear ends of the pair of side walls 422. In the present embodiment, the placement wall 423 is provided continuously with each of the side walls 422 at a position lower than the upper ends of the pair of side walls 422, and when the 2 nd division body 43 is assembled to the 1 st division body 42, the upper side of the placement wall 423 is covered with the 2 nd division body 43 as shown in fig. 22 to 25.

Further, engaging concave portions 4211 are formed on both sides of the lower end of the rear wall 421 in the Y direction so as to be recessed rearward, respectively. As shown in fig. 32, when the fitting body 41 is attached to the head 30, a pair of rear engagement projections 32112 formed on the rear portion of the cover case 321 are engaged with the pair of engagement recesses 4211, respectively. In this way, the fitting 40 is prevented from coming off the head 30.

As shown in fig. 17, a spring fixing portion 4231 to which the leaf spring 44 (i.e., an example of a biasing member) is attached is provided at a substantially central portion of the mounting wall 423 in the Y direction, and shaft portions 4232 that support the 2 nd division body 43 to be rotatable are formed on both sides of the spring fixing portion 4231 in the Y direction.

On the other hand, the 2 nd segment 43 is a segment constituting the upper part and the front part of the fitting main body 41, and as shown in fig. 16 to 19, includes a main body wall portion 431 having a shape corresponding to the upper part and the front part of the head 30.

Further, engaging concave portions 4311 are formed on both sides in the Y direction of the lower end of the main body wall portion 431 so as to be recessed forward. As shown in fig. 32, when the fitting body 41 is attached to the head 30, a pair of front engaging protrusions 32111 formed at the front of the cover case 321 are engaged with the pair of engaging recesses 4311, respectively. In this way, the fitting 40 is prevented from coming off the head 30.

Further, operation portions 4221 are formed at lower ends of substantially central portions in the X direction of the pair of side walls 422 of the 1 st division body 42, respectively. In a state where the fitting body 41 is attached to the head 30, the operation portions 4221 are pressed inward in the Y direction, respectively, so that the fitting body 41 is elastically deformed to be flattened in the X direction, and the engagement between the engagement concave portions 4211 and the rear-side engagement protrusions 32112 is released, and the engagement between the engagement concave portions 4311 and the front-side engagement protrusions 32111 is released. Thus, the fitting 40 can be detached from the head 30.

As shown in fig. 19, shaft holding portions 4312 are formed on the rear surface side of the upper portion of the main body wall portion 431 of the 2 nd division body 43, respectively, at positions corresponding to the shaft portions 4232. Further, by attaching the pair of shaft holding portions 4312 to the shaft portions 4232, the main body wall portion 431 can be rotated about the shaft portions 4232 with respect to the 1 st divided body 42. At this time, the main body wall portion 431 is attached to the 1 st division body 42 so as to cover the opening portions that open above and in front of the 1 st division body 42. Therefore, the 2 nd division body 43 rotates in the front-rear direction with respect to the 1 st division body 42.

As shown in fig. 17, the positioning wall portions 4222 are formed on the pair of side walls 422 of the 1 st divided body 42, and the pair of abutment wall portions 432 are formed on the main body wall portion 431 of the 2 nd divided body 43, and when the 2 nd divided body 43 is rotated in the closing direction, the pair of abutment wall portions 432 abut against the positioning wall portions 4222, respectively, to restrict further rotation of the 2 nd divided body 43 in the closing direction.

As shown in fig. 19, a locking wall 4223 and a through hole 4224 are formed in each of the pair of side walls 422 of the 1 st divided body 42. A pair of hooks 4313 are formed in the main body wall portion 431 of the 2 nd division body 43, and the pair of hooks 4313 can be inserted into the through holes 4224 from above and locked to the locking wall 4223 when the 2 nd division body 43 is assembled to the 1 st division body 42. Thus, when the 2 nd division body 43 is rotated in the opening direction, the hook 4313 is locked to the locking wall 4223, and further rotation of the 2 nd division body 43 in the opening direction is restricted.

As described above, in the present embodiment, as shown in fig. 22 and 23, the 2 nd divided body 43 is rotatably attached to the 1 st divided body 42 between the open position (i.e., the state where the hook 4313 is locked to the locking wall 4223: the 1 st position) and the closed position (i.e., the state where the abutment wall 432 is abutted against the positioning wall 4222: the 2 nd position). At this time, the opening width of the 2 nd division body 43 (that is, the moving distance of the 2 nd division body 43 from the closed position to the open position) can be set to be 5mm to 10 mm. In this way, the thickness of the soft sheet 50 having an opening/closing width larger than a general size (for example, a width of 40mm to 60mm, a length of 60mm to 80mm, and a thickness of 2mm to 6 mm) commercially available can be made, and when the soft sheet 50 having a general size is used, the soft sheet 50 can be easily inserted.

As shown in fig. 16 to 19, guide protrusions 4321 protruding outward in the Y direction are formed in the pair of contact wall portions 432, respectively, and when the 2 nd division body 43 is rotated, the guide protrusions 4321 move in guide grooves 4225 formed in the pair of side walls 422. Thus, the 2 nd division body 43 can be rotated more smoothly.

In the present embodiment, the 2 nd segment 43 is biased in the direction toward the closed position by a leaf spring 44 (i.e., an example of a biasing member).

Specifically, as shown in fig. 24 and 25, when the 2 nd division body 43 is assembled to the 1 st division body 42, the pressing portion 4314 formed on the upper back surface of the main body wall portion 431 is pressed by the elastically deformed leaf spring 44 (i.e., an example of the urging member). In the present embodiment, the pressing portion 4314 is provided at a position rearward of the shaft portion 4232, and a rear portion of the body wall portion 431 rearward of the shaft portion 4232 is pressed upward by the leaf spring 44 (i.e., the urging member). Thus, the 2 nd division body 43 is biased in the direction toward the closed position by the leaf spring 44 (i.e., biasing member). In the present embodiment, in the closed position (i.e., in a state in which the abutting wall portion 432 is abutted against the positioning wall portion 4222), the 2 nd division body 43 is biased in the direction toward the closed position by the leaf spring 44 (i.e., the biasing member). In this way, even when soft sheet members 50 having various thicknesses are used, each soft sheet member 50 can be more reliably held in the main body portion 1a.

In this case, in order to facilitate the opening of the 2 nd segment 43 and to suppress the occurrence of misalignment of the soft sheet body 50 during use, the load applied in the closing direction by the leaf spring 44 (i.e., the urging member) is preferably 2N to 10N.

In the present embodiment, the 2 nd segment 43 is provided with a holding portion 60 capable of holding the soft sheet 50. The holding portion 60 is configured to temporarily hold the soft sheet 50.

Specifically, the insertion port 4315 is formed in the main body wall portion 431 of the 2 nd division body 43 rotatably attached to the 1 st division body 42 in the opening/closing direction. As shown in fig. 26 and 27, the soft sheet 50 is inserted from the insertion port 4315, so that the soft sheet 50 can be temporarily held by the 2 nd divided body 43 (i.e., an element of the fitting body 41).

As described above, in the present embodiment, the insertion port 4315 into which the soft sheet 50 can be inserted and temporarily held by the soft sheet 50 is provided in the fitting body 41, and functions as the holding portion 60 capable of holding the soft sheet 50.

In the present embodiment, an insertion port 4315 is formed in an upper portion of the 2 nd division body 43 (more specifically, the main body wall 431). Thus, the soft sheet 50 can be inserted from the insertion opening 4315 more easily. Further, the soft sheet 50 inserted into the insertion port 4315 can be more reliably prevented from coming out of the insertion port 4315.

In addition, an opening 4316 through which the application portion 34 can be inserted is formed in the main body wall portion 431 of the 2 nd division body 43 at a portion corresponding to the application portion 34 so as to penetrate in the X direction. As shown in fig. 30 and 31, when the attachment 40 is attached to the head 30, the applicator 34 is inserted into the opening 4316, and the application surface 340 of the applicator 34 is exposed from the opening 4316.

When such a fitting 40 is used, the soft sheet 50 can be held by the electric razor 1 by the following method.

First, as shown in fig. 26 and 27, the soft sheet body 50 is inserted from the insertion port 4315, so that the soft sheet body 50 is temporarily held by the 2 nd divided body 43 (i.e., an element of the fitting body 41). At this time, the soft sheet body 50 is temporarily held by the 2 nd division body 43 (i.e., an element of the fitting body 41) in a state of covering the opening 4316 of the 2 nd division body 43 from the back surface side.

Next, the attachment 40 temporarily holding the soft sheet 50 is attached to the head 30 of the electric razor 1.

Thus, the soft sheet 50 is held by the electric razor 1 in a state sandwiched between the attachment 40 and the head 30.

At this time, as shown in fig. 29, the entire surface of the skin contact surface 33a of the blade portion 331 is covered with the protection wall 431e provided at the position behind the insertion port 4315 (i.e., the side where the blade portion 331 exists) of the main body wall 431. That is, when the attachment main body 41 is attached to the electric razor 1 in a state in which the soft sheet 50 is inserted from the insertion port 4315 and the soft sheet 50 is temporarily held, the protection wall 431e exists between the soft sheet 50 and the blade 331. In this way, when the soft blade 50 is held by the electric razor 1 and used, the soft blade 50 can be more reliably prevented from touching the blade 331, and breakage of the soft blade 50 and corrosion of the blade 331 can be prevented.

Further, in the present embodiment, as described above, the application portion 34 is formed to protrude from the main body portion 1a (more specifically, the base housing 310 and the cover housing 321). Therefore, when the fitting 40 is attached to the head 30, the 2 nd segment 43 moves in the opening direction, passes over the application portion 34, and moves in the closing direction after passing over the application portion 34.

In the present embodiment, when the soft sheet 50 is held by the attachment 40 and the head 30, the soft sheet 50 is pressed against the upper edge 340a of the application surface 340 by the upper side restricting wall 431a of the peripheral edge portion of the opening 4316 as the main body wall 431, against the lower edge 340b of the application surface 340 by the lower side restricting wall 431b of the peripheral edge portion of the opening 4316 as the main body wall 431, against the right edge 340c of the application surface 340 by the right side restricting wall 431c of the peripheral edge portion of the opening 4316 as the main body wall 431, and against the left edge 340d of the application surface 340 by the left side restricting wall 431d of the peripheral edge portion of the opening 4316 as the main body wall 431.

That is, when the accessory body 41 is attached to the electric razor 1 in a state in which the soft sheet 50 is inserted from the insertion port 4315 and the soft sheet 50 is temporarily held, at least two sides (desirably, 4 sides) of the application surface 340 are pressed by the accessory body 41 with the soft sheet 50 interposed therebetween. Further, the two opposite sides of the application surface 340 are pressed by the fitting body 41 with the soft sheet body 50 interposed therebetween.

In this way, even when the electric razor 1 is slid forward, backward, leftward and rightward, misalignment or deflection of the soft sheet 50 can be suppressed when the soft sheet 50 is used for performing an operation on the skin S.

As shown in fig. 30 to 32, the attachment 40 can be attached to the head 30 of the electric razor 1 without holding the soft sheet 50, and the application surface 340 of the application unit 34 can be brought into contact with the skin S to apply the skin S in a state where only the attachment 40 is attached to the head 30.

Further, the hair removing device set 100 having such a configuration can be used in the 1 st use mode, the 2 nd use mode, the 3 rd use mode, and the 4 th use mode of the electric razor 1.

Hereinafter, a brief description will be given of a method of using the electric razor 1 in each mode of use. Fig. 33 is a diagram for explaining a method of using the electric razor 1 according to embodiment 1 in the 1 st mode of use. Fig. 34 is a diagram for explaining a method of using the electric razor 1 according to embodiment 1 in the 2 nd mode of use. Fig. 35 is a diagram for explaining a method of using the electric razor 1 according to embodiment 1 in the 3 rd mode of use. Fig. 36 is a diagram for explaining a method of using the electric razor 1 according to embodiment 1 in the 4 th mode of use.

First, as shown in fig. 33, the electric razor 1 can be used in the 1 st use mode. Specifically, the user turns on the power supply of the electric razor 1 by operating the power switch 1111, and the control unit 66 switches to the 1 st use mode in which the shaving (i.e., one example of hair removal) and the application of the skin S are simultaneously performed.

Then, the user holds the handle 111 by hand to move the skin contact surface 33a and the 1 st operation surface 3411 over the skin S while simultaneously contacting the skin S.

In this way, the beard of the skin S is shaved by the blade portion 331, and the application of the skin S (for example, application of a weak current to the skin S, application of heat to the skin S, vibration of the skin S, and the like) is performed by the 1 st application portion 341.

As shown in fig. 34, the electric razor 1 can be used in the 2 nd mode of use. Specifically, the control unit 66 switches to the 2 nd use mode in which only the skin S is applied.

For example, the user can perform this operation by operating the changeover switch 1112 to change over the operation state of the operation section 34.

Then, the user holds the handle 111 by hand to move the 2 nd application surface 3421 of the 2 nd application portion 342 over the skin S while contacting the skin S. At this time, the skin contact surface 33a of the blade portion 331 is not in contact with the skin S.

In this way, the beard is not cut (i.e., an example of hair removal), but the skin S is subjected to the application (e.g., weak current is applied to the skin S, heat is applied to the skin S, and the skin S is vibrated) only by the 2 nd application portion 342.

At this time, if the control unit 66 stops driving the driving lever 315, wasteful consumption of the rechargeable battery built in the electric razor 1 can be suppressed.

As shown in fig. 35, the electric razor 1 can be used in the 3 rd use mode. The 3 rd usage pattern is the following usage pattern as in the 2 nd usage pattern: the shaving is not cut (i.e., an example of removing hair), but the application of the skin S is performed only by the 2 nd application portion 342 (e.g., applying a weak current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

Specifically, the user holds the handle 111 of the electric razor 1 to which the attachment 40 having the soft sheet body 50 temporarily not held is attached by hand, and moves the 2 nd operation surface 3421 of the 2 nd operation portion 342 exposed from the attachment 40 over the skin S while contacting the skin S.

By attaching the attachment 40 in this manner, the blade portion 331 can be more reliably prevented from coming into contact with the skin S when the skin S is applied by the 2 nd application portion 342. In addition, if the blade portion 331 does not contact the skin S at the time of performing the application of the skin S by the 2 nd application portion 342, even when the driving lever 315 is unintentionally driven due to a malfunction of the switch or the like, the blade portion 331 can be suppressed from contacting the skin S.

As shown in fig. 36, the electric razor 1 can be used in the 4 th mode of use. The 4 th usage pattern is also the following usage pattern as in the 2 nd usage pattern: the shaving is not cut (i.e., an example of removing hair), but the application of the skin S is performed only by the 2 nd application portion 342 (e.g., applying a weak current to the skin S, applying heat to the skin S, vibrating the skin S, etc.).

Specifically, the user holds the handle 111 of the electric razor 1 in which the soft sheet 50 is held by the attachment 40 by hand, and moves the soft sheet 50 covering the 2 nd operation surface 3421 of the 2 nd operation portion 342 exposed from the attachment 40 over the skin S while contacting the skin S.

At this time, if the soft sheet body 50 impregnated with the lotion, the cleaning liquid, or the like is brought into contact with the skin S, the skin S can be subjected to an operation (for example, a weak current is applied to the skin S, heat is applied to the skin S, the skin S is vibrated, or the like) while the lotion or the like is made to permeate into the skin S or dirt of the skin S is removed.

Further, if the soft sheet body 50 not impregnated with the liquid is brought into contact with the skin S, the skin S can be subjected to an operation (for example, a weak electric current is applied to the skin S, heat is applied to the skin S, and the skin S is vibrated) while shaving cream, dirt, or the like adhering to the skin S is wiped off by the soft sheet body 50.

In this way, if the electric razor 1 is used in the 4 th use mode, the skin S can be more efficiently applied. The application includes removal of soil.

(embodiment 2)

The electric razor 1 (i.e., an example of a hair removing device) of the present embodiment has a structure substantially similar to the structure of the electric razor 1 described in embodiment 1. That is, as shown in fig. 37 to 42, the electric razor 1 (i.e., an example of a hair removing device) of the present embodiment also includes: a main body 1a; a blade portion 331 provided in the main body portion 1a, which is capable of removing hair; and an application unit 34 that is provided independently of the blade unit 331 in the main body unit 1a and is capable of performing the application of the skin S. Fig. 37 is a perspective view showing an electric razor 1 as a hair removing device according to embodiment 2. Fig. 38 is a side view showing the electric razor 1 of embodiment 2. Fig. 39 is a perspective view showing a cover case 321 of the electric razor 1 according to embodiment 2. Fig. 40 is a perspective view showing the electric razor 1 and the soft sheet 50 according to embodiment 2. Fig. 41 is a perspective view showing a state in which the electric razor 1 of embodiment 2 holds a soft sheet 50. Fig. 42 is a side view showing a state in which the electric razor 1 of embodiment 2 holds a soft sheet 50.

In the present embodiment, the soft sheet body 50 held by the electric razor 1 can be used in contact with the skin S when the skin S is applied by the application unit 34.

In the present embodiment, the main body 1a is provided with a holding portion 60 that can hold the soft sheet body 50 in a state where the soft sheet body 50 covers the application surface 340 of the application portion 34.

Specifically, a band-shaped wall portion 32113 extending in the Z direction is integrally formed at a portion of the cap housing 321 that is present on both sides of the applicator 34 in the Y direction, and an insertion hole 32114 that penetrates in the Y direction is formed between the cap housing 321 and the band-shaped wall portion 32113. Further, by inserting both sides of the soft sheet 50 into the pair of left and right insertion holes 32114, the electric razor 1 can hold the soft sheet 50 in a state in which the application surface 340 of the application portion 34 is covered with the soft sheet 50. As described above, in the present embodiment, the holding portion 60 is constituted by the band-shaped wall portion 32113 and the insertion hole 32114.

In the present embodiment, as shown in fig. 38, the application surface 340 of the application portion 34 protrudes outward from the band-shaped wall portion 32113 in a side view (i.e., in a state of being viewed along the Y direction). In this way, the contact of the application surface 340 of the application portion 34 with the skin S is not hindered by the band-shaped wall portion 32113.

When the electric razor 1 having such a structure is used, the configuration can be used in the 1 st use mode, the 2 nd use mode, and the 4 th use mode described in embodiment 1. That is, the electric razor 1 can be used in the 1 st use mode, namely: the shaving beard of the skin S is shaved by the blade portion 331, and the 1 st application portion 341 is brought into direct contact with the skin S to apply the skin S. The electric razor 1 may be used in the 2 nd mode, namely: the 2 nd surgical part 342 is directly contacted with the skin S, and only the skin S is subjected to the surgical operation. The electric razor 1 may be used in the 4 th mode, namely: the soft sheet 50 is held by the electric razor 1, and the soft sheet 50 covering the 2 nd operation portion 342 is brought into contact with the skin S, whereby only the operation of the skin S is performed.

[ action, effect ]

The following describes the characteristic structure of the hair removing device, the fitting, and the hair removing device set shown in the above embodiments and the effects obtainable thereby.

The attachment 40 shown in embodiment 1 is an attachment 40 that can be detachably attached to the electric razor 1 (i.e., one example of a hair removal device). The electric razor 1 (i.e., an example of a hair removal device) to which the attachment 40 is detachably attached includes: a main body 1a; a blade portion 331 provided in the main body portion 1a, which is capable of removing hair; and an application unit 34 that is provided independently of the blade unit 331 in the main body unit 1a and is capable of performing the application of the skin S.

The fitting 40 includes: a fitting body 41 detachably mountable to the electric razor 1 (i.e., an example of a hair removing device); and a holding portion 60 provided to the fitting body 41.

The attachment 40 is configured such that, in a state where the attachment main body 41 is attached to the electric razor 1 (i.e., one example of a hair removal device), the soft sheet 50 covers the application surface 340 of the application portion 34, and the holding portion 60 can hold the soft sheet 50.

The hair removing device kit 100 according to embodiment 1 includes the electric razor 1 (i.e., an example of a hair removing device) and the accessory 40.

As described above, in embodiment 1, the holding portion 60 is formed in the attachment 40 that can be detachably attached to the electric razor 1 (i.e., one example of a hair removal device), and the soft sheet 50 in a state of covering the application surface 340 of the application portion 34 can be held by the holding portion 60.

In this way, the application unit 34 can be brought into contact with the skin S via the soft sheet body 50 to perform the application of the skin S. For this reason, for example, a sheet capable of holding a liquid can be used as the soft sheet 50, and the soft sheet 50 can be brought into contact with the skin S in a state where the soft sheet 50 impregnated with the cosmetic water, the cleaning liquid, or the like is held by the holding portion 60. In addition, if the hair removal device kit 100 is used in this way, it is possible to efficiently permeate the skin S or efficiently remove dirt from the skin S.

In addition, the soft sheet 50 may be brought into contact with the skin S in a state where the soft sheet 50 not impregnated with the liquid is held by the holding portion 60. Further, if the hair removal device kit 100 is used in this way, shaving cream, dirt, and the like adhering to the skin S can be wiped off by the soft sheet body 50.

In this way, when the holding portion 60 is formed in the attachment 40 that can be detachably attached to the electric razor 1 (i.e., one example of a hair removal device), the skin S can be more efficiently applied.

Further, since the holding portion 60 is formed in the attachment 40, the soft sheet body 50 can be held and used by the conventional electric razor 1 having the hair removal function and the operation function (i.e., an example of a hair removal device).

The fitting body 41 may include a 1 st divided body 42 and a 2 nd divided body 43 formed of a member independent of the 1 st divided body 42.

In this way, if the fitting body 41 is constituted by a plurality of divided bodies, even when the application portion 34 is projected from the body portion 1a so as to be easily brought into contact with the skin S, the fitting body 41 can be attached to the electric razor 1 without being obstructed by the application portion 34 (i.e., one example of a hair removing device). That is, even when the operation portion 34 protrudes from the main body portion 1a, the soft sheet body 50 can be more easily held by the electric razor 1 (i.e., an example of a hair removal device).

The 2 nd segment 43 may be rotatably attached to the 1 st segment 42.

In this way, if the plurality of divided bodies are integrated, the convenience of use of the fitting 40 can be improved.

The 2 nd segment 43 may be rotatably attached to the 1 st segment 42 between an open position (i.e., the 1 st position) and a closed position (i.e., the 2 nd position). The 2 nd segment 43 may be biased in the direction toward the closed position (i.e., the 2 nd position) by a leaf spring 44 (i.e., an example of a biasing member).

In this way, even when soft sheet members 50 having various thicknesses are used, each soft sheet member 50 can be more reliably held in the main body 1a. As a result, various types of soft sheet 50 having different thicknesses can be used.

Further, a holding portion 60 may be provided on the 2 nd division body 43, and the holding portion 60 may be configured to temporarily hold the soft sheet body 50.

In this way, by attaching the attachment 40, which temporarily holds the soft sheet 50, to the main body portion 1a, the soft sheet 50 can be held by the electric razor 1 (i.e., an example of a hair removal device). As a result, the soft sheet 50 can be more easily held by the electric razor 1 (i.e., an example of the hair removing device). Further, the occurrence of the dislocation of the soft sheet 50 when the soft sheet 50 is held by the electric razor 1 (i.e., an example of the hair removing device) can be more reliably suppressed. As a result, the soft sheet 50 can be held at a more appropriate position of the electric razor 1 (i.e., an example of the hair removing device).

The holding portion 60 may be an insertion port 4315 into which the soft sheet 50 is inserted and which temporarily holds the soft sheet 50.

In this way, the soft sheet 50 can be temporarily held to the fitting 40 only by inserting the soft sheet 50 into the insertion port 4315, and thus temporary holding of the soft sheet 50 to the fitting 40 can be more easily performed.

In addition, in a state where the attachment main body 41 is disposed so as to be attached to the electric razor 1 (i.e., an example of a hair removing device) by being moved downward from above, the insertion port 4315 may be formed in an upper portion of the 2 nd divided body 43.

In this way, the soft sheet 50 can be more easily inserted from the insertion port 4315, and the soft sheet 50 inserted into the insertion port 4315 can be more reliably prevented from coming out of the insertion port 4315.

The attachment main body 41 may be provided with a protection wall 431e, and the protection wall 431e may be provided between the soft sheet 50 and the blade 331 when the attachment main body 41 is attached to the electric razor 1 (i.e., an example of a hair removing device) in a state in which the soft sheet 50 is inserted from the insertion port 4315 and the soft sheet 50 is temporarily held.

In this way, when the soft sheet 50 is held by the electric razor 1 (i.e., an example of a hair removal device) and used, the soft sheet 50 can be more reliably prevented from touching the blade 331. As a result, breakage of the soft sheet body 50 due to contact with the blade portion 331 can be more reliably suppressed. In addition, since the blade 331 can be more reliably prevented from being corroded by the liquid impregnated into the soft sheet body 50, the deterioration of the blade 331 can be more reliably prevented.

In addition, in a state where the attachment main body 41 is attached to the electric razor 1 (i.e., one example of the hair removing device), the entire surface of the skin contact surface 33a of the blade portion 331 may be covered with the protection wall 431 e.

In this way, the blade portion 331 can be protected by the protection wall 431e when the attachment main body 41 is attached to the electric razor 1 (i.e., an example of a hair removal device). Therefore, the accessory 40 can be used as a blade guard of the electric razor 1 (i.e., one example of a hair removal device) when not in use.

In addition, when the attachment main body 41 is attached to the electric razor 1 (that is, an example of a hair removing device) in a state in which the soft sheet 50 is inserted from the insertion port 4315 and the soft sheet 50 is temporarily held, at least two sides of the application surface 340 may be pressed by the attachment main body 41 with the soft sheet 50 interposed therebetween.

In this way, when the soft sheet 50 is used for the skin S, the soft sheet 50 can be more reliably prevented from being displaced.

Further, the two opposite sides of the application surface 340 may be pressed by the fitting body 41 with the soft sheet member 50 interposed therebetween.

In this way, when the electric razor 1 (i.e., the hair removing device) is slid in the direction in which the two sides are pressed against the fitting body 41 during the application of the skin S using the soft sheet 50, the soft sheet 50 can be prevented from being displaced or deflected. As a result, the skin S can be more effectively applied.

The electric razor 1 (i.e., an example of a hair removal device) according to embodiment 2 includes: a main body 1a; a blade portion 331 provided in the main body portion 1a, which is capable of removing hair; an application unit 34 that is provided independently of the blade unit 331 in the main body unit 1a, and is capable of performing an application of the skin S; and a holding portion 60 provided in the main body portion 1a, capable of holding the soft sheet 50 in a state where the soft sheet 50 covers the application surface 340 of the application portion 34.

In this way, the skin S can be applied more efficiently. Further, if the holding portion 60 is provided in the main body portion 1a, the soft sheet 50 can be held by the main body portion 1a with a simpler structure.

The holding portion 60 may be integrally formed with the main body portion 1 a.

In this way, the holding portion 60 can be prevented from being lost as in the case where the holding portion 60 is detachably attached to the main body portion 1 a.
