[0027] In addition, in the following embodiments, as the electric hair cutting device, a trimmer that mainly cuts body hair of humans or animals, or eyebrow hair as hair is exemplified.

[0028] Here, in this embodiment, the longitudinal direction of the handle of the trimmer is defined as the up-down direction Z, the width direction of the handle 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.

[0029] In addition, in the present embodiment, the side of the handle portion where the head is arranged is set as the upper side in the up-down direction, and the side of the handle portion where the switch portion is arranged is set as the front side in the front-back direction.

[0030] Furthermore, in the present embodiment, the linear reciprocating direction of the movable knife (the reciprocating sliding direction of the movable knife) is defined as the knife moving direction W.

[0031] (Implementation Method)

[0032] like Figure 1 to Figure 4 As shown, the trimmer (electric hair cutting device) 10 of this embodiment includes a handle 20 that can be held by hand and a head 30 provided with a blade unit 40 and supported by the handle 20. The trimmer 10 is a device for treating or arranging eyebrows H of a user, etc. by cutting the eyebrows H of the user, etc. to a desired length, for example.

[0033] [An example of the structure of a trimmer]

[0034] Next, an example of the structure of the trimmer 10 will be described.

[0035] In this embodiment, the trimmer 10 includes a synthetic resin housing 11 formed by joining a plurality of split bodies. A cavity is formed inside the housing 11 formed by joining the split bodies, and various electrical components are accommodated in the cavity. The plurality of split bodies can be joined, for example, by using screws or by fitting the split bodies together.

[0036] In the present embodiment, a motor (not shown), a power supply unit (not shown) for driving the motor, etc. are housed in a cavity formed inside the housing 11. In addition, a motion conversion unit 60 for converting the rotational motion of the motor into a translational motion is housed in the cavity formed inside the housing 11. As the motion conversion unit 60, a conventionally known motion conversion unit can be used. In the present embodiment, an arm 61 connected to a drive rod 43a of a bushing 43 described later is housed inside the housing 11, and the motion conversion unit 60 for converting the rotational motion of the motor into a linear reciprocating motion of the arm 61 is housed.

[0037] Furthermore, as described above, in the present embodiment, the trimmer 10 includes the handle portion 20 and the head portion 30 .

[0038] The handle portion 20 is formed in a cylindrical shape that is elongated in the vertical direction Z, and is formed to be large enough for the user to hold it with one hand.

[0039] The head 30 is integrally connected to the upper side of the handle 20 in the vertical direction Z, and a knife unit 40 is provided on the head 30 (see Figure 2 ), the blade unit 40 has the function of cutting the eyebrows (hair) H. In this embodiment, as Figure 5 and Figure 6 As shown, the knife unit 40 includes a knife portion (knife of an electric hair cutting device) 44, which is formed by arranging a movable plate (movable knife) 45 and a fixed plate (fixed knife) 46 in a manner opposite to each other. The knife portion 44 is configured so that a movable knife tooth 452 described later of the movable plate 45 slides back and forth along the knife moving direction W relative to a fixed knife tooth 462 described later of the fixed plate 46.

[0040] And, if Figure 3 and Figure 4 As shown, the knife unit 40 includes a synthetic resin base portion 41 on which a knife portion 44 is arranged. In addition, the knife unit 40 includes a pressing spring 42 fixed to the fixed plate 46 and used to press the movable plate 45 toward the fixed plate 46 side, and a bushing 43 fixed to the movable plate 45 by heat sealing.

[0041] The base portion 41 is a member that forms a part of the outer contour of the head portion 30 when the blade unit 40 is attached to the handle portion 20 (see Figure 2 The base portion 41 includes a hook portion 41 a for engaging the fixing plate 46 and preventing the fixing plate 46 from being separated from the base portion 41 , a positioning protrusion 41 b for preventing the fixing plate 46 from being displaced, and a rib 41 c for preventing the pressing spring 42 from being displaced.

[0042] The pressing spring 42 is a member for more reliably making the movable blade teeth 452 and the fixed blade teeth 462 slide in contact with each other by pressing the movable plate 45 toward the fixed plate 46. The pressing spring 42 includes a through hole 42a through which the hook portion 41a and the positioning protrusion 41b pass, a positioning hole 42b through which the rib 41c passes, and a fixing piece 42c for fixing the fixed plate 46. In the present embodiment, the through hole 42a is formed to be larger than the hook portion 41a and the positioning protrusion 41b, and the positioning hole 42b is formed to have an inner diameter that is substantially the same size as the outer diameter of the positioning protrusion 41b. Therefore, the pressing spring 42 is positioned relative to the base portion 41 by allowing the positioning protrusion 41b to pass through the positioning hole 42b.

[0043] The bushing 43 is a drive coupling member mounted on the movable plate 45. The bushing 43 includes a pair of drive rods 43a connected to the arm portion 61 of the motion conversion portion 60 and a protrusion 43b formed between the pair of drive rods 43a.

[0044] The movable plate 45 includes a main body 451. A through hole 451a through which the hook 41a and the positioning protrusion 41b pass, a through hole 451b through which the protrusion 43b passes, and a pair of through holes 451c through which the pair of driving rods 43a pass are formed in the main body 451. In addition, the bushing 43 is fixed to the movable plate 45 by heat sealing in a state where the protrusion 43b passes through the through hole 451b and the pair of driving rods 43a pass through the pair of through holes 451c.

[0045] In this embodiment, the through hole 451a is formed larger than the hook 41a and the positioning protrusion 41b. In addition, the movable plate 45 can reciprocate at least along the knife moving direction W relative to the base 41 with the hook 41a and the positioning protrusion 41b inserted into the through hole 451a.

[0046] Furthermore, the movable plate 45 includes, on one end side of the main body 451 , a plurality of movable blade teeth 452 arranged in parallel along the blade moving direction W and a plurality of movable blade grooves 453 formed between adjacent movable blade teeth 452 .

[0047] The fixing plate 46 includes a main body 461. The main body 461 is provided with an engagement hole 461a engaged with the hook 41a and a through hole 461b through which the positioning protrusion 41b passes. The fixing plate 46 is fixed to the base 41 by engaging the hook 41a with the engagement hole 461a and passing the positioning protrusion 41b through the through hole 461b. At this time, the fixing plate 46 is fixed to the base 41 in a state where the relative movement of the fixing plate 46 with respect to the base 41 along the knife moving direction W is restricted.

[0048] Furthermore, the fixing plate 46 includes, on one end side of the main body 461 , a plurality of fixing blade teeth 462 arranged in parallel along the blade moving direction W and a plurality of fixing blade grooves 463 formed between adjacent fixing blade teeth 462 .

[0049] The blade unit 40 having such a structure can be assembled, for example, by the method shown below. The method shown below is just an example, and the blade unit 40 can be assembled by various methods.

[0050] First, the pressing spring 42 is attached to the base 41 in a positioned state by inserting the hook 41 a and the positioning protrusion 41 b of the base 41 into the through hole 42 a of the pressing spring 42 and inserting the positioning protrusion 41 b into the positioning hole 42 b .

[0051] Next, with the protrusion 43b inserted into the through hole 451b and the pair of drive rods 43a respectively inserted into the pair of through holes 451c, the bushing 43 is integrated with the movable plate 45 by heat sealing. Alternatively, the knife unit 40 may be assembled after the bushing 43 and the movable plate 45 are integrated in advance.

[0052] Next, the hook portion 41 a and the positioning protrusion 41 b of the base portion 41 are inserted into the through hole 451 a of the movable plate 45 integrated with the bushing 43 , so that the movable plate 45 is disposed on the pressing spring 42 .

[0053] Next, the hook portion 41a of the base portion 41 is engaged with the engagement hole 461a of the fixing plate 46 and the positioning protrusion 41b is passed through the through hole 461b, thereby fixing the fixing plate 46 to the base portion 41. At this time, the fixing piece 42c of the pressing spring 42 is fixed to the end portion of the root side of the fixing plate 46 (the side opposite to the side where the fixing blade teeth 462 and the fixing blade grooves 463 are formed).

[0054] By doing this, assembling Figure 3 The knife unit 40 is shown.

[0055] Furthermore, in this embodiment, Figure 3 The blade unit 40 shown is detachably mounted on the handle portion 20. In the present embodiment, the movable blade teeth 452 and the fixed blade teeth 462 protrude forward in the front-rear direction X when the blade unit 40 is mounted on the handle portion 20.

[0056] The knife unit 40 is mounted on the handle 20 in a state where the drive rod 43a of the bushing 43 is connected to the arm 61. In this way, when the motor is driven, the movable plate 45 reciprocates relative to the fixed plate 46 in the knife moving direction W in conjunction with the reciprocating motion of the arm 61 in the knife moving direction W.

[0057] Then, the head 30 having the knife portion 44 is formed by covering the fixing plate 46 side with the cover 50 while the knife unit 40 is mounted on the handle 20. At this time, the top ends of the movable knife teeth 452 and the fixed knife teeth 462 are exposed from the housing 31 constituting the housing of the head 30.

[0058] In the present embodiment, the trimmer 10 is configured such that the angle θ1 formed by the knife moving direction (the reciprocating sliding direction of the movable knife) W and the vertical direction (the length direction of the handle 20) is an acute angle (see Figure 1 The angle θ1 is determined based on the operability when the trimmer 10 is used to cut the eyebrows (hair) H, and is preferably set to 45° or less.

[0059] By doing so, it is possible to reduce the difference in the operational feeling when the trimmer 10 is moved in one direction of the width direction Y as the main operational direction and in the other direction of the width direction Y. As a result, the trimmer 10 can be used without discomfort in both directions, one side and the other side of the width direction Y, and the usability of the trimmer 10 can be further improved.

[0060] Specifically, it is possible to Figure 5 As shown, the eyebrow (hair) H is cut by bringing the fixed plate (fixed blade) 46 side of the blade portion 44 into contact with the skin (skin surface) S as an example of the target site.

[0061] In addition, it is also possible to Figure 6 As shown, the eyebrow (hair) H is cut by bringing the movable plate (movable blade) 45 side of the blade portion 44 into contact with the skin (skin surface) S as an example of the target site.

[0062] In addition, in the present embodiment, a slide-type operation switch 21 for operating the trimmer 10 (turning the power on and off) is formed on the housing 11. In addition, in the present embodiment, the slide-type operation switch 21 is exemplified as a switch, but as long as it is a switch that can turn the power on and off, it may also be a push-type or other switch.

[0063] In the present embodiment, the operation switch 21 is provided on the front surface (front face: outer surface) 20a of the handle portion 20 so as to be slidable in the vertical direction Z. Specifically, by sliding the operation switch 21 from the lower side toward the upper side in the vertical direction Z, the power of the trimmer 10 is switched from off to on. In addition, by sliding the operation switch 21 from the upper side toward the lower side in the vertical direction Z, the power of the trimmer 10 is switched from on to off.

[0064] Thus, in this embodiment, by sliding the operation switch 21 upward, the power of the trimmer 10 is switched from off to on. Moreover, by switching the power of the trimmer 10 from off to on, the motor is driven, and the motion conversion unit 60 converts the rotation of the motor into the linear reciprocating motion of the arm 61. Moreover, by the linear reciprocating motion of the arm 61, the movable plate 45 linearly reciprocates relative to the fixed plate 46. Moreover, the movable blade teeth 452 reciprocate relative to the fixed blade teeth 462, and the eyebrow (hair) H introduced between the fixed blade groove 463 and the movable blade groove 453 is clamped and cut by the movable blade teeth 452 and the fixed blade teeth 462.

[0065] In addition, in this embodiment, the movable blade teeth 452 slide back and forth in a planar close contact state with respect to the fixed blade teeth 462. That is, when the movable plate 45 is linearly reciprocated relative to the fixed plate 46, the movable plate 45 and the fixed plate 46 are in contact with each other on the sliding contact surface P1 (refer to Fig.10 and Fig.11 ) sliding contact.

[0066] Furthermore, in the present embodiment, the attachment 100 for adjusting the length of the cut eyebrows (hairs) H (the length after cutting) can be detachably mounted on the trimmer 10 .

[0067] [An example of the structure of the accessory]

[0068] Next, an example of the structure of the attachment 100 will be described.

[0069] The accessory 100 is detachably mounted on the trimmer 10 and is used to adjust the length (length after cutting) of the eyebrows (hairs) H introduced between the fixed blade teeth 462 and the movable blade teeth 452. Fig.12 As shown, the length (length after cutting) of the eyebrows (hairs) H is adjusted by moving the attachment 100 attached to the trimmer 10 from the outside to the inside of the eyebrows (hairs).

[0070] In the present embodiment, the accessory 100 is configured to be mounted on the trimmer 10 by being relatively moved along the blade moving direction W relative to the trimmer 10 (see FIG. 1 ). Figure 7 and Figure 8 ).

[0071] like Fig. 9 As shown, the accessory 100 includes a ring-shaped (including substantially ring-shaped) comb portion 110, which can be formed using a synthetic resin material, for example, and the comb portion 110 is formed with an insertion hole 120 in the center for inserting the head 30 having the blade portion 44. And, when the upper end of the head 30 is inserted into the insertion hole 120 and the accessory 100 is mounted on the trimmer 10, the comb portion 110 is arranged around the blade portion 44.

[0072] Furthermore, an engaging portion (not shown) that engages with each other is formed between the attachment 100 and the trimmer 10 , so that the attachment 100 attached to the trimmer 10 can be more reliably prevented from being detached.

[0073] The comb part 110 includes a plurality of comb teeth 130 arranged in a state of being separated in one direction (the blade moving direction W) and a connecting part 140 connecting the plurality of comb teeth 130. In addition, the comb part 110 includes a protective member 150, which is arranged at both ends of the comb part 110 in the blade moving direction W, and is used to improve (reinforce) the strength of the comb part 110 (accessory 100). The protective member 150 is connected to the comb teeth 130 arranged on both sides by the connecting part 140, and limits the cutting range of the eyebrows (hair) H (the range in the blade moving direction W) when the accessory 100 is used.

[0074] As described above, in the present embodiment, a plurality of comb teeth 130 are arranged in parallel in a state of being separately arranged along the blade moving direction W. By doing so, an introduction hole 160 is formed between the comb teeth 130 adjacent to each other along the blade moving direction W, and the introduction hole 160 can introduce the eyebrows (hair) H guided by the comb teeth 130 to the inner side (between the fixed blade teeth 462 and the movable blade teeth 452).

[0075] Here, in this embodiment, when the accessory 100 is mounted on the trimmer 10, the introduction hole 160 is formed in the accessory 100 in the range from both sides (the fixed blade tooth 462 side and the movable blade tooth 452 side) of the blade portion 44 to the tip.

[0076] Moreover, the plurality of comb teeth 130 form a skin contact surface 130a that contacts the skin (skin surface) S when the fixed blade tooth 462 side is located at a lower position, and another skin contact surface 130b that contacts the skin (skin surface) S when the movable blade tooth 452 side is located at a lower position.

[0077] In addition, the protective member 150 is formed with a skin contact surface 152a that contacts the skin (skin surface) S when the fixed blade tooth 462 side is located at a lower position, and another skin contact surface 152b that contacts the skin (skin surface) S when the movable blade tooth 452 side is located at a lower position.

[0078] In this way, the accessory 100 of this embodiment is constructed to be able to select a first usage mode in which one side of the blade 44 (the fixed blade tooth 462 side) is pressed against the skin S and a second usage mode in which the other side of the blade 44 (the movable blade tooth 452 side) is pressed against the skin S.

[0079] That is, when the accessory 100 is installed on the trimmer 10, skin contact surfaces are provided on both sides of the plurality of comb teeth 130 and the protective member 150 in the width direction Y, so that the length of the eyebrows H (the length after cutting) can be adjusted on both sides of the blade 44.

[0080] In this way, the operability of the trimmer 10 to which the attachment 100 is attached can be further improved or the shaving efficiency can be further improved.

[0081] Here, the length of the eyebrow H (length after cutting) after using the trimmer 10 equipped with the accessory 100 is determined based on the distance from the skin contact surface (plane) 130a, 130b to the cutting point (the sliding contact surface P1 of the movable blade tooth 452 and the fixed blade tooth 462).

[0082] In this embodiment, a pair of engaging protrusions 1311a are formed on the inner surface side of the comb teeth 130 so as to face each other. When the accessory 100 is mounted on the trimmer 10, the engaging protrusions 130c are respectively inserted into a pair of engaging grooves 31a formed in the housing 31 of the head 30. And, by engaging the engaging protrusions 1311a with the engaging grooves 31a, the relative movement of the accessory 100 with respect to the head 30 is suppressed. In this way, the distance from the skin contacting surfaces (flat surfaces) 130a, 130b to the cutting point becomes a predetermined distance.

[0083] In addition, if the distance from the skin contacting surface (plane) 130a, 130b to the cutting point is changed, the length of the eyebrow H (the length after cutting) will also change.

[0084] That is, by simply changing the distance from the skin contacting surfaces (flat surfaces) 130a, 130b to the cutting point, the length of the eyebrow H (the length after cutting) can be set to a desired length.

[0085] In the present embodiment, the length of the eyebrows H (the length after cutting) can be changed in stages.

[0086] Specifically, three mutually opposing and paired engaging protrusions 1311a are formed on the inner surface side of the comb teeth 130, and the paired engaging protrusions 1311a can respectively engage with a pair of engaging grooves 31a (see Fig.10 ).

[0087] Furthermore, by appropriately selecting the pair of engagement protrusions 1311 a that engage with the pair of engagement grooves 31 a , the length of the eyebrows H (the length after cutting) can be selected from three types.

[0088] Furthermore, in order to cut the lying hairs and unify them into a desired length after cutting, it is necessary to cut the hairs while making them stand up when cutting with the blade 44 .

[0089] Therefore, in the present embodiment, the comb teeth 130 and the protection member 150 are formed so that the top portions 130c and 152c are thinner, so that the lying hair can be more reliably raised during cutting.

[0090] Specifically, the combing part 110 is formed such that the angle between one skin contact surface 130a, 152a and the other skin contact surface 130b, 152b is an acute angle. The angle is preferably less than 70°, for example. In this way, the skin contact surface of the comb teeth 130 and the protective member 150 functions as a hair raising part that makes the prostrated hair stand up.

[0091] In addition, in the present embodiment, the comb teeth 130 and the protective member 150 are formed so that the tops 130c and 152c are located on the extension line of the sliding contact surface P1 when the accessory 100 is mounted on the trimmer 10 (see Fig.10 and Fig.11 ). By doing so, when either the first usage mode or the second usage mode is selected, substantially equal raising force can be obtained.

[0092] However, when eyebrows H with relatively many fallen hairs are cut to a desired length as in the present embodiment, the eyebrows H may not be sufficiently raised, and it is difficult to make the length after cutting to the target length.

[0093] When the length after cutting cannot be unified to the target length, the same hair must be cut several times to achieve the target length, which takes a lot of time.

[0094] Therefore, in this embodiment, even when cutting relatively many hairs lying down like the eyebrows H, it is possible to more reliably stand them up and cut them to a target length more quickly.

[0095] Specifically, the comb teeth 130 include the raising comb teeth (first comb teeth) 1310 having a relatively high raising force.

[0096] In this embodiment, the hair raising comb teeth (first comb teeth) 1310 include a main body 1311, and when the accessory 100 is mounted on the trimmer 10, the main body 1311 is arranged to be opposite to the housing 31 of the head 30. In addition, the hair raising comb teeth (first comb teeth) 1310 include a hair trimming portion 1312, which is connected to the main body 1311 and is used to trim the eyebrows H when in use.

[0097] The trimming portion 1312 is formed to be thinner on the top side, and when viewed along the knife moving direction W, flat surfaces are formed on both sides of the knife portion 44 on the main body 1311 side of the trimming portion 1312 (both sides in the width direction Y), and the flat surfaces are inclined toward the top side and inward.

[0098] In this embodiment, the flat surface inclined toward the tip side and the inner side becomes the skin contact surface that contacts the skin S when in use. Specifically, when the accessory 100 is mounted on the trimmer 10, the flat surface located on one side in the width direction Y (the fixed blade teeth 462 side) becomes a skin contact surface 1312a that contacts the skin S when the first usage mode is selected (see Fig.13 ). Moreover, when the accessory 100 is mounted on the trimmer 10, the flat surface on the other side (the movable blade tooth 452 side) in the width direction Y becomes another skin contact surface 1312b that contacts the skin S when the second usage mode is selected (see Fig.14 ).

[0099] Furthermore, in the present embodiment, by making the tip of the hair raising comb teeth (first comb teeth) 1310 thinner, the hair raising property of eyebrows H with many lying hairs can be further improved.

[0100] Specifically, the hair-styling portion 1312 includes a hair-raising groove 1312d formed to be continuous with the top end of one skin-contacting surface 1312a and a hair-raising groove 1312c formed to be continuous with the top end of the other skin-contacting surface 1312b.

[0101] In this embodiment, at the top end side of one skin contact surface 1312a, a hair raising groove 1312d protruding inward is formed in a manner connected to the top end of one skin contact surface 1312a. In addition, at the top end side of the other skin contact surface 1312b, a hair raising groove 1312c protruding inward is also formed in a manner connected to the top end of the other skin contact surface 1312b.

[0102] Furthermore, the top end of the hair raising groove 1312d and the top end of the hair raising groove 1312c are connected by the top portion 1312e.

[0103] Thus, in the present embodiment, the hair-styling portion 1312 is formed in a hollowed-out shape, and the hollowed-out portion on the tip side lifts up the lying hair (eyebrows H) to make the lying hair (eyebrows H) stand up.

[0104] Specifically, when the first use mode is selected and one skin contact surface 1312a is brought into contact with the skin S, the hair raising groove 1312c formed to be connected to the top of the other skin contact surface 1312b functions as a hair raising portion for raising the prostrated hair (see Fig.13 ).

[0105] On the other hand, when the second use mode is selected and the other skin contact surface 1312b is brought into contact with the skin S, the hair raising groove 1312d formed to be connected to the top of the one skin contact surface 1312a functions as a hair raising portion for raising the prostrated hair (see Fig.14 ).

[0106] In this way, both the surfaces defining the hair raising comb teeth (first comb teeth) 1310 in the width direction Y are configured to function as the hair raising portion and as the skin contacting portion.

[0107] By doing so, the fluff raising force on both sides of the blade portion 44 can be further increased.

[0108] However, when all the plurality of comb teeth 130 are set as the hair raising comb teeth (first comb teeth) 1310, the hair raising grooves 1312c and 1312d are formed on both sides of the blade 44, so the skin S may be excessively inserted into the hair raising grooves 1312c and 1312d when the accessory 100 is used. In this way, if the skin S is excessively inserted into the hair raising grooves 1312c and 1312d, the distance from the skin S to the cutting point may vary depending on the location, and the length of the eyebrow H (the length after cutting) may become uneven.

[0109] Therefore, in this embodiment, the comb teeth 130 also include skin-adhering comb teeth (second comb teeth) 1320 which have a lower hair raising force than the hair raising comb teeth (first comb teeth) 1310 and mainly have the function of skin-adhering, thereby preventing the skin S from getting stuck in the hair raising grooves 1312c and 1312d.

[0110] That is, the plurality of comb teeth 130 include a component that is a mixture of a hair raising comb tooth (first comb tooth) 1310 having both hair raising and skin contacting functions and a skin contacting comb tooth (second comb tooth) 1320 having a function as a skin contacting surface for unifying the cutting height to a target height.

[0111] In this embodiment, the skin-adhering comb teeth (second comb teeth) 1320 include a main body 1321, which is arranged to be opposite to the housing 31 of the head 30 when the accessory 100 is mounted on the trimmer 10. In addition, the skin-adhering comb teeth (second comb teeth) 1320 include a hair-styling portion 1322, which is connected to the main body 1321 and is used to tidy up the eyebrows H when in use.

[0112] The trimming portion 1322 is formed to be thinner on the top side, and when viewed along the knife moving direction W, flat surfaces are formed on both sides of the knife portion 44 on the main body 1321 side of the trimming portion 1322 (both sides in the width direction Y), and the flat surfaces are inclined toward the top side and inward.

[0113] In this embodiment, the flat surface inclined toward the tip side and the inner side becomes the skin contact surface that contacts the skin S when in use. Specifically, when the accessory 100 is mounted on the trimmer 10, the flat surface located on one side in the width direction Y (the fixed blade teeth 462 side) becomes a skin contact surface 1322a that contacts the skin S when the first usage mode is selected (see Fig.13 In addition, when the accessory 100 is mounted on the trimmer 10, the flat surface on the other side (the movable blade tooth 452 side) in the width direction Y becomes another skin contact surface 1322b that contacts the skin S when the second usage mode is selected (see Fig.14 ).

[0114] In addition, when the first usage mode is selected, the other skin contact surface 1322b raises the eyebrows H with a lower hair raising force than the hair raising comb teeth (first comb teeth) 1310. In addition, when the second usage mode is selected, the one skin contact surface 1322a raises the eyebrows H with a lower hair raising force than the hair raising comb teeth (first comb teeth) 1310.

[0115] Furthermore, the top of one skin contact surface 1322a and the top of the other skin contact surface 1322b are connected by the top portion 1322c.

[0116] Thus, in this embodiment, no hair raising groove is formed in the hair trimming portion 1322 of the skin contacting comb tooth (second comb tooth) 1320. Therefore, the contour shape of the skin contacting comb tooth (second comb tooth) 1320 when viewed along the blade moving direction W is different from the contour shape of the hair raising comb tooth (first comb tooth) 1310.

[0117] Furthermore, in the present embodiment, the contour shape of the protection member 150 (the contour shape when viewed along the blade moving direction W) is the same as (including substantially the same as) the contour shape of the skin contacting comb teeth (second comb teeth) 1320 .

[0118] That is, the protective member 150 includes a main body 151, which is arranged to face the housing 31 of the head 30 when the accessory 100 is mounted on the trimmer 10. In addition, the protective member 150 includes a hair trimming portion 152, which is connected to the main body 151 and is used to trim the eyebrows H when in use.

[0119] The trimming portion 152 is formed to be thinner at the tip end, and when viewed along the knife moving direction W, flat surfaces are formed on both sides (both sides in the width direction Y) of the knife portion 44 on the main body 151 side of the trimming portion 152, and the flat surfaces are inclined toward the tip end and inward.

[0120] In this embodiment, the flat surface inclined toward the tip side and the inner side becomes the skin contact surface that contacts the skin S and limits the cutting range when in use. Specifically, the flat surface located on one side (the fixed blade tooth 462 side) in the width direction Y when the accessory 100 is mounted on the trimmer 10 becomes a skin contact surface 152a that contacts the skin S when the first usage mode is selected. Moreover, the flat surface located on the other side (the movable blade tooth 452 side) in the width direction Y when the accessory 100 is mounted on the trimmer 10 becomes another skin contact surface 152b that contacts the skin S when the second usage mode is selected.

[0121] Furthermore, the top end of one skin contact surface 152a and the top end of the other skin contact surface 152b are connected by a top portion 152c.

[0122] As described above, the protective member 150 is a member for improving (reinforcing) the strength of the comb portion 110 (accessory 100). Therefore, in the present embodiment, the protective member 150 is formed to have a thickness (width in the blade moving direction W) thicker than the thickness (width in the blade moving direction W) of the skin contacting comb teeth (second comb teeth) 1320.

[0123] In addition, in the present embodiment, the thickness (width in the blade moving direction W) of the hair raising comb teeth (first comb teeth) 1310 is substantially the same as the thickness (width in the blade moving direction W) of the skin contacting comb teeth (second comb teeth) 1320. Therefore, the thickness (width in the blade moving direction W) of the protective member 150 is thicker than the thickness (width in the blade moving direction W) of the hair raising comb teeth (first comb teeth) 1310.

[0124] Furthermore, by disposing such protective members 150 at both ends of the comb portion 110 in the blade moving direction W, the pair of protective members 150 limits the cutting range (range in the blade moving direction W) of the eyebrows (hair) H when the attachment 100 is used.

[0125] Furthermore, in this embodiment, a skin contact surface 1312a of the hair raising comb tooth (first comb tooth) 1310, a skin contact surface 1322a of the skin contact comb tooth (second comb tooth) 1320, and a skin contact surface 152a of the protective component 150 are flush (including substantially flush).

[0126] Similarly, the other skin contact surface 1312b of the hair raising comb tooth (first comb tooth) 1310, the other skin contact surface 1322b of the skin contact comb tooth (second comb tooth) 1320, and the other skin contact surface 152b of the protective component 150 are flush (including substantially flush).

[0127] Therefore, when the first usage mode is selected, one skin contact surface 1321a, 1322a, 152a contacts the skin S, and when the second usage mode is selected, the other skin contact surface 1321b, 1322b, 152b contacts the skin S.

[0128] At this time, in order to increase the hair raising power of the hair raising comb teeth (first comb teeth) 1310, two locations (two skin contact surfaces) of the comb part 110 need to be in contact with the skin S. That is, the hair raising comb teeth (first comb teeth) 1310 need to be present between the skin contact surfaces.

[0129] Therefore, in this embodiment, two types of comb teeth are arranged in parallel in a manner such that there is one or more combination C in which one or more hair raising comb teeth (first comb teeth) 1310 are arranged between two skin contacting comb teeth (second comb teeth) 1320 (see Fig. 9 ).

[0130] That is, at least one hair raising comb tooth (first comb tooth) 1310 and a plurality of skin contacting comb teeth (second comb teeth) 1320 are arranged in parallel in a manner such that there is one or more combinations C in which one or more hair raising comb teeth 1310 are arranged between two skin contacting comb teeth 1320 .

[0131] In the present embodiment, there are two combinations C in which one or more hair raising comb teeth (first comb teeth) 1310 are arranged between two skin contacting comb teeth (second comb teeth) 1320 .

[0132] Specifically, if Fig. 9 As shown, the skin-adhering comb teeth (second comb teeth) 1320 are arranged at the upper end (position adjacent to the protective member 150) in the blade moving direction W. Furthermore, two hair-raising comb teeth (first comb teeth) 1310 are arranged in parallel in a row below the skin-adhering comb teeth (second comb teeth) 1320 arranged at the upper end, and one skin-adhering comb tooth (second comb tooth) 1320 is arranged in parallel in a row below the skin-adhering comb teeth (second comb teeth) 1310. Furthermore, two such combinations C are arranged in parallel in a row.

[0133] At this time, the skin-contacting comb teeth (second comb teeth) 1320 with the hair raising comb teeth (first comb teeth) 1310 adjacently arranged on the upper and lower sides serve as a combination C on one side of the knife moving direction W and a combination C on the other side.

[0134] Furthermore, as long as the hair raising comb teeth (first comb teeth) 1310 and the skin contacting comb teeth (second comb teeth) 1320 are arranged as described above, the skin contacting comb teeth (second comb teeth) 1320 can be prevented from being adjacent to each other in the blade moving direction W in two combinations C arranged in a row. In other words, the skin contacting comb teeth (second comb teeth) 1320 can be prevented from being partially adjacent to each other in the blade moving direction W.

[0135] In this case, since the two places (two skin-applying comb teeth 1320) are pressed against the skin S, the lying hair is stood up by the hair-raising comb teeth (first comb teeth) 1310 existing therebetween, and thus the hair-raising efficiency of the hair-raising comb teeth (first comb teeth) 1310 can be further improved.

[0136] Furthermore, the distance between two adjacent skin-applying comb teeth (second comb teeth) 1320 sandwiching the hair-raising comb teeth (first comb teeth) 1310 is preferably a distance that is sufficient to prevent eyebrows from getting caught while achieving the hair-raising effect.

[0137] Specifically, the distance between two adjacent skin-contacting comb teeth (second comb teeth) 1320 separated by the hair-raising comb teeth (first comb teeth) 1310 is preferably 5.0 mm or less. The reason is that if the distance between two adjacent skin-contacting comb teeth 1320 separated by the hair-raising comb teeth 1310 is greater than 5.0 mm, the eyebrows (skin S) will get stuck between the two skin-contacting comb teeth 1320 or in the hair-raising grooves of the hair-raising comb teeth 1310.

[0138] In the present embodiment, the distance between two adjacent skin contacting comb teeth (second comb teeth) 1320 sandwiching the hair raising comb teeth (first comb teeth) 1310 is set to about 1.7 mm.

[0139] In addition, in the present embodiment, since the trimmer 10 for cutting the eyebrows H is illustrated, the distance between the two skin-contacting comb teeth (second comb teeth) 1320 adjacent to each other across the hair-raising comb teeth (first comb teeth) 1310 is set to a distance that does not allow the eyebrows to get caught. However, this distance can be appropriately set according to the purpose of the electric hair cutting device.

[0140] [Function, Effect]

[0141] Hereinafter, the characteristic structure of the attachment of the electric hair cutting device shown in the above-mentioned embodiment and the effects obtained thereby will be described.

[0142] (1) The accessory of the electric hair cutting device shown in the above embodiment is installed on the electric hair cutting device having a blade portion in a detachable manner. Moreover, the accessory of the electric hair cutting device is configured to select a first usage mode in which a first side of the blade portion is placed against the skin and a second usage mode in which a second side of the blade portion opposite to the first side is placed against the skin and used. The accessory of the electric hair cutting device shown in the above embodiment includes a comb portion arranged around the blade portion in a state of being installed on the electric hair cutting device. Moreover, the comb portion includes a first comb tooth, the first comb tooth having a first skin contact surface that contacts the skin when the first usage mode is selected, a second skin contact surface that contacts the skin when the second usage mode is selected, a first hair raising groove portion formed on the side of the first skin contact surface, and a second hair raising groove portion formed on the side of the second skin contact surface.

[0143] In this way, by attaching the attachment so as to surround the blade of the electric hair cutting device, hair can be cut more safely.

[0144] Furthermore, since the comb portion includes the first comb teeth having hair raising grooves formed on both sides, the lying hair can be more reliably raised when either the first usage mode or the second usage mode is selected.

[0145] As a result, hair can be cut into desired length more quickly without cutting off the same hair several times until reaching the desired length. In addition, since the cut-off length of hair can be made to become a more uniform length, the effect of the hair after the cut-off can be further optimized.

[0146] (2) In addition, according to the accessory of the electric hair cutting device described in (1), the comb part may further include second comb teeth, the second comb teeth having a third skin contact surface that contacts the skin when the first use mode is selected and a fourth skin contact surface that contacts the skin when the second use mode is selected. Furthermore, the fourth skin contact surface may be used for hair raising when the first use mode is selected, and the third skin contact surface may be used for hair raising when the second use mode is selected.

[0147] In this way, since the comb teeth (first comb teeth) with enhanced hair raising power are mixed with the comb teeth (second comb teeth) mainly used for skin contact, it is possible to suppress the skin from being excessively caught in the hair raising groove while suppressing the hair raising effect from being reduced. As a result, not only can the lying hair be raised more reliably, but the cut length of the hair can also be made more uniform.

[0148] (3) In addition, according to the accessory of the electric hair cutting device described in (2), at least one first comb tooth and a plurality of second comb teeth may be arranged in parallel in such a manner that there is one or more combinations in which one or more first comb teeth are arranged between two second comb teeth.

[0149] This can more reliably prevent the skin from getting stuck in the hair raising grooves.

[0150] (4) In addition, according to the accessory of the electric hair cutting device of (3) above, there may be a plurality of locations in the comb portion where a combination of at least one first comb tooth is arranged between two second comb teeth and arranged in parallel in a continuous manner. Furthermore, in the combination of the continuous and parallel arrangements, the second comb teeth may be arranged in parallel in a non-adjacent manner.

[0151] In this case, since the comb teeth (second comb teeth) mainly used for skin contact are not arranged continuously in the combination of continuous parallel arrangement, it is possible to more reliably suppress a decrease in the hair raising power.

[0152] (5) In addition, according to any one of the accessories of the electric hair cutting device described in (2) to (4), protective members may be formed at both ends of the comb portion, the protective members being used to reinforce the comb portion and having a skin contact surface for limiting the hair cutting range during use. Furthermore, the protective member may be formed to have a contour shape that is the same as (including substantially the same as) the second comb teeth and a thickness that is thicker than the thickness of the second comb teeth.

[0153] In this case, the strength of the comb portion can be improved by utilizing the protective member having the skin contact surface for limiting the hair cutting range during use, and damage to the accessories caused by external impact, drop impact, etc. can be more reliably suppressed.

[0154] [other]

[0155] The contents of the accessories of the electric hair cutting device of the present disclosure have been described above, but it is obvious to those skilled in the art that the accessories are not limited to the above description and various modifications and improvements can be made.

[0156] For example, a comb portion in which a combination of one or more first comb teeth is arranged between two second comb teeth may exist only partially.

[0157] Furthermore, the specifications (shape, size, layout, etc.) of the connecting portion, the protective member, and other detailed parts can also be changed appropriately.

[0158] As described above, the attachment of the electric hair cutting device of the present disclosure can more reliably stand up the lying hair, and thus can be applied to attachments of various electric hair cutting devices, including those for home use and business use.
