[0001] The present invention relates to a blade of a hair remover and a hair remover having the blade. Background Art

[0002] In the past, as disclosed in the following patent documents 1 and 2, a blade of a hair clipper (hair removal device) has been proposed for cutting hair by reciprocatingly sliding a comb-toothed movable blade having movable blade teeth and movable blade grooves relative to a comb-toothed fixed blade having fixed blade teeth and fixed blade grooves.

[0003] Here, in Patent Document 1, the distance between the front ends of adjacent fixed blades is made narrower toward the front ends, and the distance between adjacent movable blades is made wider toward the front ends. Thus, a shedding prevention portion is provided at the front ends of the fixed blades to suppress shedding of hair introduced into the groove, thereby improving the introduction of hair and thus improving the hair cutting efficiency.

[0004] In addition, in Patent Document 2, the blade angle of the sliding contact surface between the fixed blade and the movable blade is made acute, thereby reducing the burden on the movable blade and improving the hair cutting efficiency.

[0027] The following describes the implementation in detail with reference to the accompanying drawings. However, there are cases where a more detailed description than necessary is omitted. For example, a detailed description of a well-known matter or a repeated description of a substantially identical structure may be omitted.

[0028] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present invention, and are not intended to limit the subject matter described in the claims.

[0029] In the following embodiments, a trimmer (electric hair cutting device) for cutting body hair or hair of a human or an animal is exemplified as a hair removing device.

[0030] Here, in this embodiment, the longitudinal direction of the base of the trimmer is defined as the up-down direction Z, the width direction of the base of the trimmer is defined as the width direction Y, and the direction orthogonal to the up-down direction Z and the width direction Y is defined as the front-rear direction X.

[0031] In this embodiment, the head is arranged on the upper side of the base, the vertical direction of the trimmer is defined, and the side to which the front end of the curved head (hair remover body) faces is defined as the front in the front-rear direction.

[0032] In addition, in this embodiment, the direction in which the fixed blade and the movable blade overlap is defined as the thickness direction W for description.

[0033] (Implementation Method)

[0034] like Figure 1 and Figure 2 As shown, the trimmer (hair removal device) 1 of this embodiment includes a hair removal device body 1a and a hair removal device blade 1b held on the hair removal device body 1a. In this embodiment, the hair removal device blade 1b includes a fixed blade comb 462 and a movable blade comb 452 that is in sliding contact with the fixed blade comb 462. In addition, the hair removal device blade 1b is held on the hair removal device body 1a in a state where the fixed blade comb 462 and the movable blade comb 452 are exposed to the outside. The trimmer 1 is, for example, a device for processing or arranging the body hair (hair H) of a user or the like by cutting the body hair (hair H) of the user or the like into a desired length.

[0035] In this embodiment, the trimmer 1 includes a base 10 and a head 20 detachably mounted on the base 10. The hair remover blade 1b is held in the head housing 30 of the head 20 with the fixed blade teeth 462 and the movable blade teeth 452 exposed to the outside from the upper end.

[0036] Next, use Figure 3 and Figure 4 The schematic structure of the base portion 10 will be described.

[0037] like Figure 3 and Figure 4 As shown, the base 10 is in a generally cylindrical shape that is elongated in the vertical direction Z, and includes a housing 11 that constitutes an outer shell. The housing 11 is formed to a size that a user can hold with one hand, and when using the trimmer 1, the user can hold the housing 11 to use it. Thus, a grip portion 11a that the user can hold with his hand is formed on the housing 11. The housing 11 can be formed using, for example, a synthetic resin material having insulating properties.

[0038] In the present embodiment, the housing 11 is formed by connecting a plurality of divided bodies, and a cavity is formed inside the housing 11 formed by connecting the divided bodies. Various electrical components are housed in the cavity.

[0039] Specifically, the housing 11 includes: a substantially cylindrical cylindrical wall portion 111 extending vertically; an upper cover portion 112 configured to cover an upper opening of the cylindrical wall portion 111 ; and a battery cover 113 configured to cover a lower opening of the cylindrical wall portion 111 .

[0040] In addition, a rotating motor 12, a battery (not shown) for supplying power to the rotating motor 12, a battery base 14 for holding the battery, a control substrate (not shown) for controlling the on / off of the power supply (the on / off of the drive of the rotating motor 12), etc. are built into a cavity formed inside the housing 11.

[0041] In the present embodiment, the rotary motor 12 is built into the upper part of the housing 11 (inside the cylindrical wall 111), and the battery base 14 is built into the lower part of the housing 11 (inside the battery cover 113). At this time, in the present embodiment, the rotary motor 12 and the battery base 14 are built into the housing 11 in a state where the battery base 14 is arranged at the lower part of the rotary motor 12 in a state where the longitudinal direction is substantially consistent with the up-down direction Z. In this way, if the rotary motor 12 and the battery base 14 are arranged in the up-down direction, the radial compactness of the base 10 (housing 11) can be achieved.

[0042] In addition, in the present embodiment, the battery cover 113 is detachably mounted on the cylindrical wall portion 111, and the battery base 14 is exposed to the outside by removing the battery cover 113 from the cylindrical wall portion 111. Furthermore, by exposing the battery base 14 to the outside, the battery can be held by the battery base 14 or removed from the battery base 14. As the battery held in such a battery base 14, for example, a dry cell battery, a rechargeable battery, etc. can be used.

[0043] In addition, the rotary motor 12 includes a rotary motor body 121 and a rotary motor shaft 122, and the rotary motor shaft 122 is built into the cavity of the housing 11 in a state where the rotary motor shaft 122 protrudes upward from the rotary motor body 121. That is, the rotary motor 12 is built into the cavity of the housing 11 in a state where the rotation axis direction is substantially consistent with the up-down direction Z. In addition, the drive shaft 13 is attached to the rotary motor shaft 122 protruding upward.

[0044] In addition, a push-type power switch 11b for switching the power on and off (on and off the drive of the rotary motor 12) is formed at the lower end portion of the side portion of the cylindrical wall portion 111 in the up-down direction Z. In addition, in the present embodiment, the push-type power switch 11b is exemplified as the power switch, but a slide-type or other switch may also be used as long as it is a switch that can turn the power on and off.

[0045] In the present embodiment, the upper cover 112 and the battery cover 113 are attached to the cylindrical wall portion 111 in a state where the gap is sealed by the seal 15 .

[0046] In addition, a through hole 112a is formed at a position of the upper cover 112 corresponding to the drive shaft 13, and the rotary motor 12 is held on the upper cover 112 in a state where the drive shaft 13 mounted on the rotary motor shaft 122 is inserted into the through hole 112a. That is, in this embodiment, the drive shaft 13 is exposed to the outside of the housing 11. At this time, the rotary motor 12 is held on the upper cover 112 in a state where the gap between the rotary motor shaft 122 and the through hole 112a is sealed by the waterproof rubber 16. Thus, the trimmer 1 can be used in a bathroom or the like.

[0047] When the head portion 20 is mounted on the base portion 10 , a power transmission portion (coupling) 51 to be described later provided on the head portion 20 is mounted on the drive shaft 13 .

[0048] In addition, the drive shaft 13 can be, for example, in a top view of the base 10 (when the base 10 is viewed from the upper side in the up-down direction Z) in a regular hexagonal shape (polygonal shape). In this way, if the shape of the drive shaft 13 is a regular hexagonal shape (polygonal shape), the power transmission part (coupling) 51 can be installed on the drive shaft 13 in a state where idling is suppressed. The drive shaft 13 and the power transmission part (coupling) 51 only need to be installed in a state where idling is suppressed, and are not limited to a polygonal shape. For example, a drive shaft with a D-shaped cutting structure can also be provided. In addition, it can also be provided so that idling can be suppressed by using a means of increasing the friction between the drive shaft 13 and the power transmission part (coupling) 51.

[0049] Next, use Figure 5 and Figure 6 The schematic structure of the head 20 will be described.

[0050] like Figure 5 and Figure 6 As shown, the head 20 includes: a head housing 30 detachably mounted on the upper end of the base 10; and a blade unit 40 held by the head housing 30. Furthermore, the head 20 includes an eccentric cam block 50 as a power transmission mechanism for transmitting the power of the drive shaft 13 of the base 10 to the blade unit 40.

[0051] The head housing 30 can be formed of, for example, a synthetic resin material having insulating properties. In addition, the head housing 30 is formed by connecting a plurality of split bodies together, and a cavity is formed inside the head housing 30 formed by connecting the split bodies together. Furthermore, the blade unit 40 and the eccentric cam block 50 are accommodated in the cavity.

[0052] Specifically, the head housing 30 includes a front housing 31 and a rear housing 32, and the head housing 30 having a cavity therein is formed by connecting the front housing 31 and the rear housing 32. The blade unit 40 is built into the upper portion of the cavity of the head housing 30, and the eccentric cam block 50 is built into the lower portion of the cavity of the head housing 30.

[0053] The eccentric cam block 50 includes: a power transmission part (coupling) 51; and an operating shaft 52, which is mounted on the upper part of the power transmission part (coupling) 51 to operate. Furthermore, the eccentric cam block 50 includes: a sleeve 53, which is mounted on the head housing 30 in a state where the operating shaft 52 is embedded; and an eccentric cam 54, which is connected to the upper end of the operating shaft 52.

[0054] In the present embodiment, the eccentric cam block 50 is held on the head housing 30 in a state where the power transmission part (coupling) 51 protrudes downward. Furthermore, in the present embodiment, the power transmission part (coupling) 51 is formed with a mounting part 33 that allows the head 20 to be detachably mounted on the base part 10. And when the head 20 is mounted on the base part 10 using the mounting part 33, the power transmission part (coupling) 51 and the drive shaft 13 are connected in a state where idling is suppressed.

[0055] Specifically, a space opening downward is formed inside the power transmission part (coupling) 51, and the space is in a regular hexagonal shape (polygonal shape) in a bottom view of the head 20 (when the head 20 is viewed from the lower side in the vertical direction Z). The regular hexagonal (polygonal) space is formed to be substantially the same size as the outer diameter of the drive shaft 13, and the drive shaft 13 is inserted into the regular hexagonal (polygonal) space when the head 20 is mounted on the base 10. Thus, when the rotary motor 12 is driven, the power transmission part (coupling) 51 also rotates along with the rotation of the drive shaft 13.

[0056] The operating shaft 52 is connected to the power transmission part (coupling) 51 in a state where idling is suppressed, and rotates together with the power transmission part (coupling) 51 that rotates by the power (rotation) of the rotary motor 12 transmitted from the drive shaft 13 .

[0057] The eccentric cam 54 includes a cam body 541 connected to the upper end of the operating shaft 52 in a state where idling is suppressed, and an eccentric shaft 542 integrally formed at the upper portion of the cam body 541 at a position separated from the rotation center of the cam body 541. The eccentric cam 54 also rotates in conjunction with the rotation of the operating shaft 52.

[0058] Thus, in this embodiment, the head 20 includes an eccentric cam block (power transmission mechanism) 50 having a power transmission portion (coupling) 51 and capable of transmitting the power (rotation) of the rotary motor 12. The eccentric cam 54 of the eccentric cam block 50 is connected to the blade unit 40.

[0059] The blade unit 40 has the function of cutting the hair H. Figure 7 and Figure 8 As shown, a blade portion (the blade 1b of the hair removal device) 44 is provided, and the blade portion (the blade 1b of the hair removal device) 44 is formed by arranging a movable plate (movable blade) 45 and a fixed plate (fixed blade) 46 relative to each other. The blade portion 44 is configured so that the movable blade comb teeth 452 of the movable plate 45 reciprocate and slide relative to the fixed blade comb teeth 462 of the fixed plate 46 in the width direction Y. Thus, in this embodiment, the blade portion 44 of the blade unit 40 is equivalent to the blade 1b of the hair removal device, and the head portion 20 and the base portion 10 other than the blade portion 44 are equivalent to the hair removal device body 1a.

[0060] The movable plate 45 includes a main body 451, and a plurality of movable blade comb teeth 452 are arranged at a front end of the main body 451 at substantially equal intervals (second blade pitch P2) in a state separated in the width direction Y. In addition, a movable blade groove 453 is formed between the movable blade comb teeth 452 adjacent in the width direction Y.

[0061] Similarly, the fixed plate 46 also includes a main body 461, and a plurality of fixed blade comb teeth 462 are arranged at the front end of the main body 461 at substantially equal intervals (first blade pitch P1) in a state separated in the width direction Y. Furthermore, a fixed blade groove 463 is formed between the fixed blade comb teeth 462 adjacent in the width direction Y.

[0062] Furthermore, if Figure 7 As shown, the blade unit 40 includes: a base portion 41 made of synthetic resin, on which a fixed plate 46 is arranged; and a pressing spring 42, which presses a movable plate 45 toward the fixed plate 46. In addition, the blade unit 40 includes a driving member 43, which is mounted on the movable plate 45 and causes the movable blade comb teeth 452 of the movable plate 45 to slide back and forth in the width direction Y relative to the fixed blade comb teeth 462 of the fixed plate 46.

[0063] In this embodiment, if Figure 7As shown, a through hole 43a is formed in the driving member 43 and passes through the through hole 43a. Furthermore, by allowing the protrusion 32a of the rear housing 32 to pass through the through hole 43a, the driving member 43 is mounted on the rear housing 32 in a manner that allows the driving member 43 to swing in the width direction Y around the protrusion 32a. In addition, a shaft receiving portion 43c is formed in the driving member 43 to receive the eccentric shaft 542 of the eccentric cam 54. By rotating the eccentric shaft 542 received in the shaft receiving portion 43c, the driving member 43 is swung in the width direction Y around the protrusion 32a. Furthermore, by engaging the protrusion 43b formed on the driving member 43 with the engaging hole 451a formed on the main body 451 of the movable plate 45, the movable plate 45 is reciprocated in the width direction Y in conjunction with the swing of the driving member 43.

[0064] Thus, in the present embodiment, the rotational motion transmitted from the drive shaft 13 to the eccentric cam block 50 is converted into a reciprocating motion in the width direction Y by the driver 43, and the reciprocating motion in the width direction Y of the driver 43 is transmitted to the movable plate 45. Then, the movable plate 45 reciprocates in the width direction Y while being pressed toward the fixed plate 46 by the pressing spring 42, whereby the movable blade comb teeth 452 slide on the front surfaces (sliding contact surfaces 462a) of the fixed blade comb teeth 462. In the present embodiment, the movable blade comb teeth 452 reciprocate while being in close contact with the fixed blade comb teeth 462 in a flat surface.

[0065] In this embodiment, the main body 451 of the movable plate 45 includes a base 4511 and a curved wall 4512 connected to the front end of the base 4511 and curved toward the fixed plate 46. A plurality of movable blade comb teeth 452 are formed at the front end of the curved wall 4512.

[0066] The main body 461 of the fixed plate 46 includes a base 4611 and a curved wall 4612 connected to the front end of the base 4611 and curved toward the movable plate 45. A plurality of fixed blade comb teeth 462 are formed at the front end of the curved wall 4612.

[0067] Therefore, at the front end side of the blade portion 44 , when the movable plate 45 is reciprocated in the width direction Y, only the movable blade comb teeth 452 and the fixed blade comb teeth 462 are in sliding contact with each other.

[0068] In addition, in this embodiment, a slit 30a is formed at the upper end of the head housing 30, and the blade unit 40 is held on the head housing 30 in a state where the front ends 465a of the fixed blade comb teeth 462 and the front ends 455a of the movable blade comb teeth 452 are exposed to the outside through the slit 30a.

[0069] Furthermore, in the present embodiment, the head housing 30 is in a curved shape with the upper end located forward in the front-rear direction X, and the front ends 465a of the fixed blade comb teeth 462 and the front ends 455a of the movable blade comb teeth 452 protrude forward and upward. In addition, in the present embodiment, the fixed blade comb teeth 462 and the movable blade comb teeth 452 are arranged in an overlapping manner with the movable blade comb teeth 452 being located forward in the front-rear direction X relative to the fixed blade comb teeth 462.

[0070] Thus, in the present embodiment, the blade unit 40 is held at the front end side of the head housing 30, and the front end side of the head housing 30 is bent toward the side (the front in the front-rear direction X) where the movable blade comb teeth 452 are located among the fixed blade comb teeth 462 and the movable blade comb teeth 452. Thus, when the trimmer 1 is used, the rear surface of the fixed blade comb teeth 462 (the surface on the opposite side to the side with which the movable blade comb teeth 452 slide in contact: the skin contact surface 462b) can be brought into contact with the skin S more easily and reliably.

[0071] Thus, in this embodiment, when the power switch 11b is operated to drive the rotary motor 12, the rotation of the rotary motor 12 is transmitted to the driver 43 via the eccentric cam block 50, and is converted into reciprocating motion by the driver 43. Then, by reciprocating the driver 43, the movable plate 45 is reciprocated relative to the fixed plate 46. Then, the movable blade comb teeth 452 reciprocate relative to the fixed blade comb teeth 462, and the hair H introduced between the fixed blade groove 463 and the movable blade groove 453 is cut by the movable blade comb teeth 452 and the fixed blade comb teeth 462.

[0072] Next, use Fig. 9 and Fig.10 The specific structures of the movable blade comb teeth 452 , the fixed blade comb teeth 462 , the movable blade groove 453 , and the fixed blade groove 463 will be described.

[0073] The movable blade comb teeth 452 are formed to protrude in one direction from the main body 451, and include: a root portion 454, which is connected to the main body 451; and a front end portion 455, which is connected to the root portion 454. In this embodiment, the direction orthogonal to the direction in which the movable blade comb teeth 452 protrude (protruding direction) is the blade moving direction (reciprocating sliding direction of the movable blade: width direction Y).

[0074] Similarly, the fixed blade comb teeth 462 are also formed to protrude in one direction from the main body 461, and include: a root 464, which is connected to the main body 461; and a front end 465, which is connected to the root 464. In this embodiment, when the movable plate 45 and the fixed plate 46 are overlapped, the movable blade comb teeth 452 and the fixed blade comb teeth 462 protrude in the same direction. Therefore, in the state where the blade unit 40 is assembled, the direction in which the fixed blade comb teeth 462 protrude (protruding direction) also becomes a direction orthogonal to the blade moving direction (reciprocating sliding direction of the movable blade: width direction Y).

[0075] Furthermore, in the present embodiment, the fixed blade comb teeth 462 and the movable blade comb teeth 452 are arranged to overlap in a manner that allows them to slide in contact with each other in a state where the front end 465a of the fixed blade comb teeth 462 protrudes from the front end 455a of the movable blade comb teeth 452. And the hair H is cut in a state where the rear surface of the front end portion 465 of the fixed blade comb teeth 462 protruding from the front end 455a of the movable blade comb teeth 452 (the surface on the opposite side of the sliding contact surface 462a with which the movable blade comb teeth 452 slide: the skin contact surface 462b) is in contact with the skin S. Thus, when the trimmer 1 is used, it is possible to prevent the movable blade comb teeth 452 from directly contacting the skin S.

[0076] In addition, the movable blade comb tooth 452 has a movable side hair cutting area 456 that can cooperate with the fixed blade comb tooth 462 to cut the hair H. In the present embodiment, the area facing the fixed blade groove 463 in the front end portion 455 of the movable blade comb tooth 452 becomes the movable side hair cutting area 456. And, both sides of the width direction Y of the movable side hair cutting area 456 become the cutting portion 456a that can cut the hair H. In the present embodiment, the shape of the cutting portion 456a is made into a sharper edge, so that the hair H can be cut more reliably. The angle θ of the edge of the cutting portion 456a can be set to 45 degrees, for example.

[0077] On the other hand, the fixed blade comb teeth 462 also have a fixed side hair cutting area (cutting area) 466 that can cooperate with the movable blade comb teeth 452 to cut the hair H. In this embodiment, when viewed along the thickness direction W, the area that can overlap with the movable side hair cutting area 456 becomes the fixed side hair cutting area (cutting area) 466. And both sides of the width direction Y of the fixed side hair cutting area (cutting area) 466 become cutting parts 466a that can cut the hair H.

[0078] In addition, the movable blade groove 453 is formed between two adjacent movable blade comb teeth 452 in the width direction (reciprocating sliding direction of the movable blade) Y in a manner that opens toward the front end side of the protruding direction of the movable blade comb tooth 452. That is, for the movable blade groove 453, the front end side of the movable blade comb tooth 452 becomes the opening side 453a, and the root side of the movable blade comb tooth 452 becomes the inner side 453b.

[0079] Similarly, the fixed blade groove 463 is formed between two adjacent fixed blade comb teeth 462 in the width direction (reciprocating sliding direction of the movable blade) Y in a manner that opens toward the front end side of the protruding direction of the fixed blade comb teeth 462. That is, for the fixed blade groove 463, the front end side of the fixed blade comb teeth 462 becomes the opening side 463a, and the root side of the fixed blade comb teeth 462 becomes the back side 463b.

[0080] In addition, in the present embodiment, the movable blade comb teeth 452 are formed into a tapered shape with a tapered tip when viewed along the thickness direction W. Therefore, the movable blade groove 453 is formed so that the groove width in the width direction (reciprocating sliding direction of the movable blade) Y increases from the inner side 453b toward the opening side 453a.

[0081] On the other hand, the fixed blade comb teeth 462 are formed so that the blade widths in the width direction (the reciprocating sliding direction of the movable blade) Y are substantially the same when viewed along the thickness direction W in the fixed side hair cutting region (cutting region) 466. Therefore, the fixed blade groove 463 is formed so that the groove widths in the width direction (the reciprocating sliding direction of the movable blade) Y are substantially the same in the portion corresponding to the fixed side hair cutting region (cutting region) 466.

[0082] Here, in the present embodiment, the blade 1 b of the hair remover can be used more safely while suppressing a decrease in the efficiency of cutting the hair H.

[0083] Specifically, the blade width W1 of the front end portion 465 of the fixed blade comb tooth 462 is larger than the groove width W2 of the portion of the fixed blade groove 463 facing the fixed side hair cutting area (cutting area) 466. As a result, the front end portion 465 of the fixed blade comb tooth 462 can be more reliably in contact with the skin S surface, and the contact area of ​​the front end portion 465 of the fixed blade comb tooth 462 with the skin S can be increased. That is, when the blade 1b of the hair removal device is used (when the blade 1b of the hair removal device is used in contact with the skin S), the contact area of ​​the tip of the fixed blade with the skin (skin surface) S can be increased. In addition, the front end portion 465 of the fixed blade comb tooth 462 can firmly press the skin S, and when the blade 1b of the hair removal device is used, the irritation caused by the fixed blade comb tooth 462 to the skin S can be more reliably reduced. At this time, a variable portion may be provided to change the contact area between the blade tip of the fixed blade and the skin (skin surface) S, so that the contact area between the blade tip of the fixed blade and the skin (skin surface) S can be adjusted according to the site of use.

[0084] In addition, in the present embodiment, the blade width W1 of the front end portion 465 of the fixed blade comb tooth 462 is larger than the blade width of the fixed side hair cutting region (cutting region) 466. In addition, the opening width of the fixed blade groove 463 is made smaller than the groove width W2 by utilizing both ends of the width direction Y of the front end portion 465. Thus, it is possible to suppress the hair H introduced into the fixed blade groove 463 from falling off from the opening of the fixed blade groove 463, and it is possible to suppress the reduction in the cutting efficiency of the hair H.

[0085] In addition, in this embodiment, the blade pitch P1 of the fixed blade comb teeth 462 is larger than the blade pitch P2 of the movable blade comb teeth 452. Thus, the chance of the hair H introduced into the fixed blade groove 463 being cut by the movable blade comb teeth 452 can be increased, and the situation of the hair H cutting efficiency being reduced can be suppressed.

[0086] Furthermore, in the present embodiment, the thickness T1 of the front end portion 465 of the fixed blade comb tooth 462 (the thickness of the blade tip portion of the fixed blade) is greater than the thickness T2 of the fixed side hair cutting region (cutting region) 466 (the blade thickness at the blade groove portion of the fixed blade groove 463 that becomes the cutting portion 466a of the fixed blade comb tooth 462). In addition, the thickness T1 of the front end portion 465 of the fixed blade comb tooth 462 is greater than the thickness T3 of the main body 461.

[0087] In this embodiment, the front end of the fixed blade comb tooth 462 is bent to form a thick wall portion 4651 protruding to the opposite side of the side in sliding contact with the movable blade comb tooth 452 at the front end portion 465 of the fixed blade comb tooth 462, thereby making the thickness T1 of the front end portion 465 thicker.

[0088] Therefore, in the present embodiment, the fixed blade comb tooth 462 is in a shape in which the front end portion 465 is bent toward the opposite side of the side with which the movable blade comb tooth 452 slides in contact with the fixed side hair cutting area (cutting area) 466. That is, in the present embodiment, the front end portion 465 of the fixed blade comb tooth 462 includes: a bent portion 4652 connected to the fixed side hair cutting area (cutting area) 466; and a thick wall portion 4651 connected to the bent portion 4652.

[0089] Furthermore, in the present embodiment, no edges are formed on the outer surface 4651a of the thick-walled portion 4651. Specifically, when observed from any of the width direction Y, the thickness direction W, and the direction orthogonal to the width direction Y and the thickness direction W, the contour shape of the thick-walled portion 4651 is a shape formed by curved lines and straight lines protruding outward. Such a shape can be obtained, for example, by grinding the corners of the thick-walled portion 4651. In addition, it is also possible to form no edges on the tip of the fixed blade (the front end portion 465 of the fixed blade comb teeth 462) by making the entire circumference of the fixed blade a curved surface.

[0090] Furthermore, by forming the front end portion 465 of the fixed blade comb teeth 462 into such a shape, when the fixed plate (fixed blade) 46 side of the blade portion (the blade of the hair removal device) 44 is used in contact with the skin (skin surface) S, the thick wall portion 4651 contacts the skin (skin surface) S. This can improve safety during use and improve skin touch.

[0091] Furthermore, instead of performing the bending process on the front end of the fixed blade comb teeth 462 , the thickness T1 of the front end portion 465 may be made thicker by forging a metal plate material.

[0092] In addition, in the present embodiment, the movable blade comb teeth 452 and the fixed blade comb teeth 462 are arranged in such a manner that the front end 465a of the fixed blade comb teeth 462 protrudes outward from the front end 455a of the movable blade comb teeth 452. Furthermore, in the present embodiment, the length L1 of the thick wall portion 4651 in the protruding direction of the fixed blade comb teeth 462 is shorter than the length L2 from the front end 465a of the fixed blade comb teeth 462 to the front end 455a of the movable blade comb teeth 452 (refer to Fig.10 ).

[0093] Thus, the movable side hair cutting area 456 of the movable blade comb teeth 452 is arranged in the thin area (fixed side hair cutting area 466) of the fixed blade comb teeth 462, so that the hair H can be cut shorter more reliably.

[0094] In addition, if the length L1 is shorter than the length L2, it is possible to prevent the skin contact surface 462b of the fixed side hair cutting area 466 from being blocked from contacting the skin S by the thick wall portion 4651. As a result, it is possible to prevent the cut hair H from remaining in a long state, and the hair H can be cut shorter more reliably.

[0095] In addition, in order to prevent the skin contact surface 462b of the fixed side hair cutting area 466 from being blocked from contacting the skin S by the thick wall portion 4651, the length L1 needs to be shorter. However, if the length L1 is shorter, the strength of the fixed blade comb teeth 462 is reduced. On the other hand, if the length L1 is longer, the strength of the fixed blade comb teeth 462 can be maintained, but the hair H may not be cut shorter.

[0096] Therefore, in this embodiment, the length L1 is set to a length that can prevent the cut hair H from remaining in a long state while suppressing the reduction in the strength of the fixed blade comb teeth 462. Thus, the shape of the plurality of fixed blade comb teeth 462 is made into a shape in which the flat portion touches the skin (skin surface) S when the blade 1b of the hair removal device is used (when the blade 1b of the hair removal device is used in contact with the skin S).

[0097] Furthermore, in the present embodiment, the thickness T4 of the movable-side hair cutting region 456 and the thickness T2 of the fixed-side hair cutting region 466 are substantially equal.

[0098] If the trimmer 1 is configured in this way, the irritation of the fixed blade comb teeth 462 to the skin S can be more reliably reduced, so that even when the trimmer 1 is used on a soft part of the skin S, it can be used more safely.

[0099] In addition, the trimmer 1 may be configured to have only the above-mentioned head 20, that is, a hair removal device having only one type of head. However, the trimmer 1 shown in the above-mentioned embodiment may be used as one of the personal care kits in which heads having various functions can be mounted on the common base 10. That is, the trimmer 1 may also have other heads having different functions of the action part.

[0100] For example, in addition to the head 20, it is also possible to include Fig.12 and Fig.13 Thus, for example, after the relatively long hair H is cut using the head 20, the hair H can be cut shorter using the trimming head 60.

[0101] like Fig.12 and Fig.13As shown, the finishing head 60 includes: a head housing 70 detachably mounted on the upper end of the base 10; and a blade unit 80 held by the head housing 70. Furthermore, the finishing head 60 includes an eccentric cam block 90 as a power transmission mechanism for transmitting the power of the drive shaft 13 of the base 10 to the blade unit 80.

[0102] The head housing 70 can be formed of, for example, a synthetic resin material having insulating properties. In addition, the head housing 70 is formed by connecting a plurality of split bodies together, and a cavity is formed inside the head housing 70 formed by connecting the split bodies together. Furthermore, the blade unit 80 and the eccentric cam block 90 are accommodated in the cavity.

[0103] Specifically, the head housing 70 includes an upper housing 71 and a lower housing 72, and the head housing 70 having a cavity therein is formed by connecting the upper housing 71 and the lower housing 72. The blade unit 80 is built into the upper portion of the cavity of the head housing 70, and the eccentric cam block 90 is built into the lower portion of the cavity of the head housing 70.

[0104] The eccentric cam block 90 includes: a power transmission part (coupling) 91; and an operating shaft 92, which is mounted on the upper part of the power transmission part (coupling) 91 to operate. Furthermore, the eccentric cam block 90 includes: a sleeve 93, which is mounted on the head housing 70 in a state where the operating shaft 92 is embedded; and an eccentric cam 94, which is connected to the upper end of the operating shaft 92.

[0105] Furthermore, the power transmission part (coupling) 91 is provided with a mounting part 73 for detachably mounting the finishing head 60 on the base part 10. In addition, a space opening downward is formed inside the power transmission part (coupling) 91, and the space is in a regular hexagonal shape (polygonal shape) in a bottom view of the finishing head 60 (in a state where the finishing head 60 is viewed from the lower side in the vertical direction Z).

[0106] The eccentric cam 94 includes a cam body 941 connected to the upper end of the operating shaft 92 in a state where idling is suppressed, and an eccentric shaft 942 integrally formed on the upper portion of the cam body 941 at a position separated from the rotation center of the cam body 941 .

[0107] Thus, the trimming head 60 includes an eccentric cam block (power transmission mechanism) 90 having a power transmission portion (coupling) 91 capable of transmitting the power (rotation) of the rotary motor 12 . The eccentric cam 94 of the eccentric cam block 90 is connected to the blade unit 80 .

[0108] The blade unit 80 has the function of cutting the hair H. Fig.12 and Fig.13 As shown in FIG. 1 , a blade portion 84 is provided which is formed of an inner blade 85 and an outer blade 86. The blade portion 84 is configured such that the inner blade 85 reciprocates in the width direction Y relative to the outer blade 86.

[0109] Furthermore, the blade unit 80 includes a drive shaft 81 that holds the inner blade 85 and a pressing spring 82 that presses the inner blade 85 toward the outer blade 86. In addition, the blade unit 80 includes a driver 83 that is mounted on the inner blade 85 and reciprocates the inner blade 85 in the width direction Y relative to the outer blade 86.

[0110] In addition, the driving member 83 is formed with a shaft housing portion 83 c for housing the eccentric shaft 942 of the eccentric cam 94, and the driving member 83 is reciprocated in the width direction Y by rotating the eccentric shaft 942 housed in the shaft housing portion 83 c. Furthermore, the inner blade 85 mounted on the driving member 83 reciprocates in the width direction Y in conjunction with the reciprocating motion of the driving member 83.

[0111] Furthermore, if the trimming head 60 having such a structure is used and the outer surface of the outer blade 86 is brought into contact with the skin S, the hair H on the skin S can be cut shorter. In this case, a mesh blade having a plurality of blade holes formed in a mesh shape can be used as the outer blade 86. Thus, a trimmer (hair removal device) 1 that can be equipped with a mesh blade can be provided. In addition, the trimmer (hair removal device) 1 can also be provided with a structure that can be equipped with SkinGuard, so that when the blade 1b of the hair removal device is used, the blade 1b of the hair removal device does not directly contact the skin S.

[0112] [Function, Effect]

[0113] Hereinafter, the characteristic structures of the hair remover blade and the hair remover including the hair remover blade shown in the above-mentioned embodiment and the effects obtainable thereby will be described.

[0114] (Technique 1) The blade 1b of the hair removal device shown in the above embodiment includes: a fixed plate (fixed blade) 46; and a movable plate (movable blade) 45, which reciprocates and slides relative to the fixed plate (fixed blade) 46. In the blade 1b of the hair removal device, the fixed plate (fixed blade) 46 and the movable plate (movable blade) 45 are used to cut the hair H.

[0115] Here, the fixed plate (fixed blade) 46 has a plurality of fixed blade comb teeth 462 arranged at a first blade pitch P1 in the reciprocating sliding direction (Y direction) of the movable plate (movable blade) 45 relative to the fixed plate (fixed blade) 46. In addition, the fixed plate (fixed blade) 46 has a plurality of fixed blade grooves 463 formed between the adjacent fixed blade comb teeth 462 in the reciprocating sliding direction (Y direction).

[0116] On the other hand, the movable plate (movable blade) 45 has: a plurality of movable blade comb teeth 452, which are arranged at a second blade pitch P2 in the reciprocating sliding direction (Y direction); and a plurality of movable blade grooves 453, which are formed between adjacent movable blade comb teeth 452 in the reciprocating sliding direction (Y direction).

[0117] The fixed blade comb teeth 462 and the movable blade comb teeth 452 are arranged to overlap and slide in contact with each other in a state where the front ends 465 a of the fixed blade comb teeth 462 protrude beyond the front ends 455 a of the movable blade comb teeth 452 .

[0118] Furthermore, the fixed blade comb tooth 462 has: a sliding contact surface 462a that is in sliding contact with the movable blade comb tooth 452; and a skin contact surface 462b that is on the opposite side of the sliding contact surface 462a and can be in contact with the skin.

[0119] In addition, the fixed blade comb tooth 462 has a fixed-side hair cutting region (cutting region) 466 capable of cutting the hair H in cooperation with the movable blade comb tooth 452 .

[0120] And the blade width W1 of the front end 465 of the fixed blade comb tooth 462 is larger than the groove width W2 of the part facing the fixed side hair cutting area (cutting area) 466 in the fixed blade groove 463. The blade pitch P1 of the fixed blade comb tooth 462 is larger than the blade pitch P2 of the movable blade comb tooth 452.

[0121] Thus, in the blade 1b of the hair removal device shown in the above embodiment, the blade width W1 of the front end portion 465 of the fixed blade comb tooth 462 is larger than the groove width W2 of the portion of the fixed blade groove 463 facing the fixed side hair cutting area (cutting area) 466. As a result, the front end portion 465 of the fixed blade comb tooth 462 can be more reliably contacted with the skin S surface, and the contact area of ​​the front end portion 465 of the fixed blade comb tooth 462 with the skin S can be increased. Therefore, the front end portion 465 of the fixed blade comb tooth 462 can press the skin S firmly. As a result, when the blade 1b of the hair removal device is used, the irritation caused by the fixed blade comb tooth 462 to the skin S can be more reliably reduced, so even when it is used in a soft part of the skin S, the blade 1b of the hair removal device can be used more safely.

[0122] Furthermore, in the blade 1b of the hair removal device shown in the above embodiment, the blade pitch P1 of the fixed blade comb teeth 462 is larger than the blade pitch P2 of the movable blade comb teeth 452. In this way, if the interval between the blades of the movable blade comb teeth 452 is narrower than the interval between the blades of the fixed blade comb teeth 462, the chance of cutting the hair H introduced into the fixed blade groove 463 by the movable blade comb teeth 452 can be increased. As a result, the situation where the cutting efficiency of the hair H is reduced can be suppressed.

[0123] As described above, if the blade 1b of the hair remover is configured as described in the above embodiment, the blade 1b of the hair remover can be used more safely while suppressing a decrease in the efficiency of cutting the hair H.

[0124] (Technique 2) In the above (Technique 1), the thickness T1 of the front end portion 465 of the fixed blade comb tooth 462 may be greater than the thickness T2 of the fixed-side hair cutting region (cutting region) 466.

[0125] In this way, if the blade thickness of the front end 465 of the fixed blade comb tooth 462 is thicker than the blade thickness of the fixed side hair cutting area (cutting area) 466, it can be set as the blade 1b of the hair removal device with good skin touch. Furthermore, if only the front end 465 is made thicker with respect to the blade thickness of the fixed blade comb tooth 462, it is also possible to suppress the situation that the length of the hair H cut by the fixed side hair cutting area (cutting area) 466 is longer than the desired length (thickness T2). In other words, if only the front end 465 is made thicker with respect to the blade thickness of the fixed blade comb tooth 462, it can be set as the blade 1b of the hair removal device with good skin touch while suppressing the situation that the hair H cut by the fixed side hair cutting area (cutting area) 466 becomes the desired length and is hindered by the front end 465.

[0126] (Technique 3) In addition, in the above (Technique 2), the fixed plate (fixed blade) 46 may include a main body 461 connected to a plurality of fixed blade comb teeth 462, and the thickness T1 of the front end 465 of the fixed blade comb teeth 462 may be greater than the thickness T3 of the main body 461. In other words, the blade thickness of the front end 465 of the fixed blade comb teeth 462 may be thicker than the thickness of the raw material of the fixed plate (fixed blade) 46. Thus, the blade 1b of the hair removal device may be provided to have a better skin touch and be safer.

[0127] (Technique 4) In addition, in the above (Technique 3), the front end portion 465 of the fixed blade comb tooth 462 may be formed into a shape bent to the opposite side of the side on which the movable blade comb tooth 452 slides in contact with the fixed side hair cutting area (cutting area) 466.

[0128] Thus, the thickness T1 of the front end portion 465 of the fixed blade comb tooth 462 can be more easily made thicker than the thickness T3 of the main body portion 461 .

[0129] (Technology 5) In addition, in the above (Technology 4), the front end portion 465 of the fixed blade comb tooth 462 may have a thick wall portion 4651 protruding to the opposite side of the side with which the movable blade comb tooth 452 slides in contact, and the thick wall portion 4651 is formed into a shape without forming edges on the outer surface 4651a.

[0130] This can provide the blade 1b of the hair removal device that feels better on the skin and is safer.

[0131] (Technique 6) In addition, the trimmer (hair removal device) 1 shown in the above embodiment includes the blade 1b of the hair removal device described in any one of the above (Technique 1) to (Technique 5). In addition, the trimmer (hair removal device) 1 shown in the above embodiment includes a hair removal device body 1a, which holds the blade 1b of the hair removal device in a state where the front end 465a of the fixed blade comb teeth 462 and the front end 455a of the movable blade comb teeth 452 are exposed to the outside.

[0132] As described above, according to the trimmer (hair removing device) 1 shown in the above-mentioned embodiment, the trimmer (hair removing device) 1 can be used more safely while suppressing a decrease in the efficiency of cutting the hair H.

[0133] (Technique 7) In addition, in the above (Technique 6), the blade 1b of the hair removal device can be maintained on the front end side of the hair removal device body 1a, and the front end side of the hair removal device body 1a is bent toward the side (front in the front-to-back direction) where the movable blade comb tooth 452 of the fixed blade comb tooth 462 and the movable blade comb tooth 452 is located.

[0134] Thus, when the trimmer (hair removal device) 1 is used, the skin contact surface 462b side of the fixed blade comb teeth 462 can be more easily and reliably brought into contact with the skin S, thereby preventing the movable blade comb teeth 452 from directly contacting the skin S when cutting the hair H. As a result, a trimmer (hair removal device) 1 that is safer and has a good skin feel can be provided.
