Description

Technical Field

[0001] The present disclosure relates to a mesh outer blade member, a mesh outer blade formed using the mesh outer blade member, and an electric shaver including the mesh outer blade. Background Art

[0002] In the past, as shown in Patent Document 1, there is known a mesh outer blade used in an electric razor for shaving hair such as beards. In Patent Document 1, a long plate-shaped mesh outer blade member is used to form the mesh outer blade. Specifically, the mesh outer blade member is formed by bending a mesh outer blade member having a plurality of blade holes defined by a frame strip in a substantially hexagonal shape in a mesh shape in a manner that protrudes upward along the short side direction to form the mesh outer blade.

[0003] The mesh outer blade member is bent in the short-side direction so as to protrude upward to form a mesh outer blade and attached to the razor body, thereby forming an electric shaver with mesh outer blades having mesh-shaped blade holes.

DETAILED DESCRIPTION

[0026] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. However, there are cases where an overly detailed description is omitted. For example, there are cases where a detailed description of a well-known matter is omitted, or a repeated description of a substantially identical structure is omitted.

[0027] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0028] In addition, in the following embodiments, when describing the electric razor, the direction in which the plurality of blade blocks are arranged in parallel is set as the X direction and the direction in which each blade block extends is set as the Y direction for description. In this specification, the X direction is also referred to as the front-back direction or the shaving direction. In this specification, the Y direction is also referred to as the left-right direction. The Y direction is the direction in which the mesh inner blade moves relative to the mesh outer blade.

[0029] Furthermore, the up-down direction in a state where the head cover (i.e., an element of the electric shaver) is arranged with the skin contact surface facing upward is set as the Z direction (i.e., the up-down direction) for description. In addition, in the present embodiment, the skin contact surface of the blade unit is composed of the surfaces of the outer blades of the plurality of blade blocks (more specifically, the outer surfaces), and as a whole, it is a surface that can be approximated as a curved surface convex outward. Therefore, in the following embodiments, the following state is set as a state where the head (i.e., an example of the main body) is arranged with the skin contact surface facing upward: the outermost point of the protrusion of the curved surface approximating the skin contact surface of the blade unit is located at the uppermost part, and the section at the outermost point of the protrusion of the curved surface approximating the skin contact surface of the blade unit becomes a horizontal plane.

[0030] In the following embodiments, the description will be given with the side of the electric shaver where the power switch is provided being the front side in the X direction.

[0031] In addition, in the following embodiments, when the mesh outer blade member is described, the short side direction of the mesh outer blade member is set to the X direction (i.e., the second direction, more specifically, the direction that becomes the shaving direction), the long side direction of the mesh outer blade member is set to the Y direction (i.e., the first direction, more specifically, the direction that becomes the direction in which the mesh inner blade moves relative to the mesh outer blade), and the thickness direction of the mesh outer blade member is set to the Z direction (i.e., the plate thickness direction). In addition, in the following embodiments, the X direction of the mesh outer blade member is consistent with the X direction of the electric razor in a state where the mesh outer blade is set in the electric razor, and the Y direction of the mesh outer blade member is consistent with the Y direction of the electric razor in a state where the mesh outer blade is set in the electric razor.

[0032] (Implementation Method)

[0033] First, refer to Figure 1 and Figure 2 The structure of the electric shaver 1 will be described.

[0034] Figure 1 It is a front view which shows an example of the electric shaver 1 which concerns on embodiment. Figure 2 FIG. 1 is a front view showing a partially exploded view of an example of an electric shaver 1 according to an embodiment. Figure 1 and Figure 2 As shown, the electric shaver 1 of this embodiment includes a razor body 10 and a blade unit 20 held in the razor body 10 with a skin contacting surface 20a (ie, the surface of the outer blades of each blade block described later) exposed.

[0035] The razor body 10 includes a grip 11 that can be grasped by hand and a head 12 supported by the grip 11. In this embodiment, the head 12 is supported by the grip 11 in a state in which the grip 11 extends in a direction substantially consistent with the vertical direction and is tilted upward and forward.

[0036] The head 12 can be swung in the Y direction relative to the handle 11 about an unillustrated shaft extending in the X direction. The head 12 can also be swung in the X direction relative to the handle 11 about an unillustrated shaft extending in the Y direction. Furthermore, the head 12 can also be floated in the Z direction relative to the handle 11.

[0037] Furthermore, a structure combining the above swinging and floating as appropriate may be adopted. For example, a structure in which the head 12 can swing relative to the handle 11 in the X direction and the Y direction and can float relative to the handle 11 in the Z direction may be adopted.

[0038] In addition, it is also possible to adopt a structure in which the head 12 does not swing or float relative to the handle 11. In addition, it is also possible to adopt a structure in which the head 12 does not tilt relative to the handle 11.

[0039] The handle portion 11 includes a main body housing 111, and a cavity is formed inside the main body housing 111. Various electrical components such as a rechargeable battery are housed in the cavity formed inside the main body housing 111.

[0040] In addition, a push-type power switch 111a for operating the electric shaver 1 (i.e., the power switch 111a for turning the power of the electric shaver 1 on and off) is formed on the main body housing 111. In addition, in the present embodiment, a push-type switch is exemplified as the power switch 111a, but other switches such as a slide type may also be used as long as the switch can turn the power on and off.

[0041] In the present embodiment, the power switch 111a is formed on the front surface of the main body housing 111, that is, the front surface of the electric shaver 1 (that is, the front surface of the electric shaver 1). In addition, the front surface of the electric shaver 1 refers to the surface on the side opposite to the user when the user holds the grip 11 of the electric shaver 1 when it is used under normal circumstances.

[0042] In addition, a trimming unit may be provided at the rear portion of the main body housing 111 (that is, the rear portion of the electric shaver 1 ).

[0043] The head 12 includes a head body 121 mounted on the handle 11 and a head cover 122 detachably mounted on the head body 121. In the present embodiment, the head cover 122 is released from the head body 121 by retracting release buttons 121a provided at both left and right ends of the head body 121 so as to freely protrude and retract.

[0044] In addition, a driving mechanism is housed in the head body 121. The driving mechanism includes a plurality of driving rods 13, and the driving rods 13 are housed in the head body 121 in a state of protruding upward from the head body 121. As such a driving mechanism, for example, a conventionally known driving mechanism such as a vibration type linear actuator, a driving mechanism composed of a rotary motor and a conversion mechanism for converting rotary motion into reciprocating linear motion can be used.

[0045] Figure 3 It is a perspective view showing another example of the outer blade case 200 according to the embodiment. Figure 4 2 is a perspective view showing another example of the outer blade box 200 of the embodiment in a partially cutaway manner. Figure 2 The blade unit 20 shown can also be set as Figure 3 and Figure 4 The blade unit 20 shown. Here, Figure 2 The blade unit 20 shown in the figure includes three blade blocks and an outer blade housing 23, and the three blade blocks are arranged in the X direction so that the long side direction is aligned with the Y direction. Figure 3 and Figure 4 The blade unit 20 shown in the figure includes six blade blocks and an outer blade case 23 . The six blade blocks are arranged side by side in the X direction with the longitudinal direction thereof aligned with the Y direction.

[0046] Thus, in this embodiment, each blade block has a predetermined length and width, and the above-mentioned blade blocks are configured so that the length direction is roughly consistent with the Y direction (i.e., the first direction and the left-right direction) of the electric shaver 1 and the width direction is roughly consistent with the X direction (i.e., the second direction, the front-back direction and the shaving direction) of the electric shaver 1.

[0047] exist Figure 2 In the blade unit 20 shown, the three blade blocks are composed of two mesh blade blocks 21 and one slit blade block 22. Figure 3 and Figure 4 The blade unit 20 shown is composed of four net blade blocks 21 and two slit blade blocks 22 .

[0048] In addition, the mesh blade assembly 21 has the function of mainly cutting off the beard H (i.e., an example of body hair and hair) in a tilted state or the beard H (i.e., an example of body hair and hair) in a shorter state. And, the slit blade assembly 22 has the function of mainly cutting off the elongated beard H (i.e., an example of body hair and hair).

[0049] exist Figure 2 In the blade unit 20 shown in FIG. 1 , a slit blade block 22 is arranged at the center in the X direction, and two mesh blade blocks 21 are arranged on both sides of the slit blade block 22. Figure 3 and Figure 4 In the blade unit 20 shown, two mesh blade blocks 21 are arranged in the center in the X direction, and two slit blade blocks 22 are arranged on both sides of the central mesh blade block 21. In addition, the remaining two mesh blade blocks 21 are arranged on both sides of the slit blade block 22.

[0050] like Figure 2 to Figure 4 As shown, the mesh blade assembly block 21 includes a mesh outer blade 211 and a mesh inner blade 212. In the present embodiment, the mesh outer blade 211 is formed by bending in an inverted U shape so as to protrude upward when viewed from the side (i.e., when viewed along the Y direction). In addition, for each mesh outer blade 211, the curvature radius of all mesh outer blades 211 (i.e., the curvature radius of the portion bent in the inverted U shape) can be substantially the same, or the curvature radius of at least one mesh outer blade 211 can be different.

[0051] Furthermore, the mesh outer blade 211 is formed slightly curved along the Y direction (i.e. the outer blade length direction) in a manner that the upper part protrudes when the front view (i.e. the state observed along the X direction). And, the mesh outer blade 211 is formed into a state that is covered with many roughly hexagonal blade holes 33. In addition, it is also possible to be set to a structure that does not make the mesh outer blade 211 be bent in a manner that the upper part protrudes when the front view. For example, the top of the mesh outer blade 211 can be made into a straight line extending along the Y direction (i.e. the outer blade length direction) when the mesh outer blade 211 is observed from the front (i.e. the state observed along the X direction).

[0052] The mesh inner blade 212 is in the shape of an inverted letter U along the curved shape of the mesh outer blade 211, and is arranged on the inner side of the mesh outer blade 211 (i.e., the lower side of the mesh outer blade 211, more specifically, the opposite side of the mesh outer blade 211 that contacts the skin). The mesh inner blade 212 can be detachably mounted on one of the plurality of drive rods 13. Furthermore, when the power of the electric shaver 1 is turned on and the drive rod 13 is driven while the mesh inner blade 212 is mounted on the drive rod 13 and arranged on the inner side of the mesh outer blade 211, the mesh inner blade 212 is relatively displaced relative to the mesh outer blade 211 (i.e., relatively moved, more specifically, reciprocated along the Y direction) while in sliding contact with the inner surface of the mesh outer blade 211.

[0053] like Figure 4 As shown, the slit blade block 22 includes a slit outer blade 221 and a slit inner blade 222. In the present embodiment, the slit outer blade 221 is curved in an inverted U shape so as to protrude upward when viewed from the side (ie, viewed along the Y direction).

[0054] Furthermore, the slit outer blade 221 is formed slightly curved along the Y direction (i.e., the outer blade length direction) in a manner that the upper part protrudes when viewed from the front (i.e., the state observed along the X direction). And, in the slit outer blade 221, a plurality of slit-shaped blade holes extending along the X direction are formed in a manner that is arranged in a state separated in the Y direction. In addition, it is also possible to set the structure that does not make the slit outer blade 221 be bent in a manner that the upper part protrudes when viewed from the front. For example, the top of the slit outer blade 221 can be made into a straight line extending along the Y direction (i.e., the outer blade length direction) when the slit outer blade 221 is observed from the front (i.e., the state observed along the X direction). That is, the slit outer blade 221 can be formed in a manner that the top surface of the slit outer blade 221 becomes a flat surface (i.e., a plane).

[0055] like Figure 4 As shown, the slit inner blade 222 is in the shape of an inverted letter U along the curved shape of the slit outer blade 221, and is arranged on the inner side of the slit outer blade 221 (i.e., the lower side of the slit outer blade 221, more specifically, the side opposite to the side of the slit outer blade 221 that contacts the skin). The slit inner blade 222 can be detachably mounted on one of the plurality of drive rods 13 (more specifically, a drive rod 13 other than the drive rod on which the mesh inner blade 212 is mounted). Furthermore, when the power of the electric shaver 1 is turned on and the drive rod 13 is driven while the slit inner blade 222 is mounted on the drive rod 13 and arranged on the inner side of the slit outer blade 221, the slit inner blade 222 is relatively displaced relative to the slit outer blade 221 (i.e., relatively moved, more specifically, reciprocated along the Y direction) while in sliding contact with the inner surface of the slit outer blade 221.

[0056] As described above, the electric shaver 1 of the present embodiment has the form of a reciprocating electric shaver in which the mesh inner blade 212 reciprocates relative to the mesh outer blade 211 and the slit inner blade 222 reciprocates relative to the slit outer blade 221 .

[0057] And, in Figure 2 In the blade unit 20 shown, the components except the two mesh inner blades 212 in the three blade blocks are installed in the roughly frame-shaped outer blade housing 23. At this time, each component can be installed in the outer blade housing 23 detachably or in a non-detachable state.

[0058] In addition, two mesh blade blocks 21 and one slit blade block 22 are mounted on the outer blade housing 23 in a state that they can float in the Z direction (i.e., the up-down direction). In this way, when the head cover 122 with the outer blade box 200 mounted thereon is mounted on the head body 121, each blade block floats independently relative to the head 12 (i.e., an example of the main body). In this way, the outer blade (more specifically, the skin contact surface 20a of the blade unit 20) can be made to follow the shape of the skin more reliably, and the beard H (i.e., an example of body hair and hair) can be cut more reliably.

[0059] Furthermore, at least one blade block among the plurality of blade blocks may be held in the head portion 12 (ie, an example of the main body portion) in a non-floating state.

[0060] In addition, in this embodiment, if Figure 2 As shown, two mesh outer blades 211 are installed in the outer blade housing 23 without mesh inner blades 212 disposed inside, and one slit outer blade 221 is installed in the outer blade housing 23 with a slit inner blade disposed inside. Figure 2 In the blade unit 20 shown, two net-like outer blades 211 and one slit blade block 22 are mounted on an outer blade housing 23 to form an outer blade case 200. The outer blade case 200 is detachably mounted on the head cover 122.

[0061] Specifically, the head cover 122 has a substantially cylindrical peripheral wall portion 122c formed with an upper opening 122a and a lower opening 122b. And, the outer blade box 200 is installed on the head cover 122 by inserting the outer blade box 200 with each outer blade facing upward from the lower opening 122b side of the head cover 122. At this time, the outer blade box 200 is installed on the head cover 122 in a state where the surface of each outer blade is exposed from the upper opening 122a of the head cover 122. Therefore, in the present embodiment, the portion of the surface of each outer blade exposed from the upper opening 122a of the head cover 122 becomes a skin contact surface 20a that contacts the skin (i.e., skin surface) of the user.

[0062] Furthermore, release buttons 23 a are formed at both left and right ends of the outer blade case 23 , and by operating the release buttons 23 a , the head cover 122 and the outer blade case 200 are released from being mounted.

[0063] As explained above, in Figure 2 In the blade unit 20 shown, the head cover 122 with the outer blade box 200 installed is installed on the head body 121, while the two mesh inner blades 212 are respectively installed on the driving rod 13 protruding upward from the head body 121. And, when the head cover 122 with the outer blade box 200 installed is installed on the head body 121, while the two mesh inner blades 212 are respectively installed on the driving rod 13, the two mesh inner blades 212 are arranged on the inner side of the corresponding mesh outer blade 211.

[0064] In this way, when the electric shaver 1 is powered on, each inner blade is relatively displaced with respect to the corresponding outer blade (ie, relatively moved, more specifically, reciprocated in the Y direction).

[0065] On the other hand, Figure 3 and Figure 4 In the illustrated blade unit 20, all six blade blocks are mounted in a substantially frame-shaped outer blade housing 23. At this time, each member may be mounted in the outer blade housing 23 in a detachable manner or in a non-detachable state.

[0066] In addition, the four mesh blade blocks 21 and the two slit blade blocks 22 are mounted on the outer blade housing 23 in a state that they can float in the Z direction (i.e., the up-down direction). In this way, when the head cover 122 with the outer blade box 200 mounted thereon is mounted on the head body 121, each blade block floats independently relative to the head 12 (i.e., an example of the main body). In this way, the outer blade (more specifically, the skin contact surface 20a of the blade unit 20) can be made to follow the shape of the skin more reliably, and the beard H (i.e., an example of body hair and hair) can be cut more reliably.

[0067] Furthermore, at least one blade block among the plurality of blade blocks may be held in the head portion 12 (ie, an example of the main body portion) in a non-floating state.

[0068] In addition, Figure 3 and Figure 4 In the blade unit 20 shown, the four mesh blade blocks 21 are all installed in the outer blade housing 23 in a state where the mesh inner blades 212 are arranged inside the mesh outer blades 211, and the two slit blade blocks 22 are all installed in the outer blade housing 23 in a state where the slit inner blades 222 are arranged inside the slit outer blades 221. Figure 3 and Figure 4 In the illustrated blade unit 20 , four net blade blocks 21 and two slit blade blocks 22 are mounted on an outer blade housing 23 , thereby forming an outer blade case 200 .

[0069] Furthermore, the outer blade box 200 is detachably mounted on the head cover 122 .

[0070] In this way, when the electric shaver 1 is powered on, each inner blade is relatively displaced with respect to the corresponding outer blade (ie, relatively moved, more specifically, reciprocated in the Y direction).

[0071] Furthermore, when the power of the electric shaver 1 is turned on and each inner blade is relatively displaced with respect to the corresponding outer blade, the skin contact surface 20a of the blade unit 20 is brought into contact with the user's skin (i.e., the skin surface) and moves slidingly along the X direction, thereby using the outer blades and the inner blades to cut off the beard H (i.e., an example of body hair and hair) inserted into the blade hole of each outer blade.

[0072] As described above, in the present embodiment, the head portion 12 corresponds to a main body portion that holds the blade unit 20 in a state where the skin contact surface 20a is exposed.

[0073] Next, refer to Figures 5 to 8 The structure of the net-shaped outer blade member 30 used when forming the net-shaped outer blade 211 of the present embodiment will be described.

[0074] Figure 5 It is a plan view showing an example of the net-like outer blade member 30 according to the embodiment. Figure 6 This is a diagram showing an enlarged portion of a blade hole 33 formed in an example of a mesh outer blade member 30 according to the embodiment. Figure 7 This is a diagram showing a further enlarged portion of a blade hole 33 formed in an example of a mesh outer blade member 30 according to the embodiment. Figure 8 2 is a cross-sectional view for explaining the thickness of the first frame bar 321, the second frame bar 322 and the third frame bar 323 of an example of the mesh outer blade member 30 of the embodiment. Figure 5As shown, the mesh outer blade member 30 is in a substantially rectangular plate shape, and a fixing portion for fixing to an outer blade holding member is formed at the outer peripheral edge of the mesh outer blade member 30, and the outer blade holding member is mounted on the outer blade housing 23. And, in a state where the mesh outer blade member 30 is bent in an inverted U-shape so as to protrude upward when viewed along the long side direction, the fixing portion formed on the mesh outer blade member 30 is fixed to a fixing member such as an outer blade joint, thereby forming a mesh outer blade 211. In addition, it is also possible to set the mesh outer blade member 30 in a state where the mesh outer blade member 30 is bent in an inverted U-shape so as to protrude upward when viewed along the long side direction directly to the main body housing 111 (i.e., one element of the razor body 10), thereby forming an electric razor 1 having a mesh outer blade 211.

[0075] In this way, the mesh outer blade member 30 becomes a member used to form the mesh outer blade 211. In other words, the mesh outer blade member 30 becomes a raw material for forming the mesh outer blade 211. And, by fixing the mesh outer blade member 30, which is a raw material for forming the mesh outer blade 211, in a bent state to a fixing member such as an outer blade joint or the main body housing 111, a part of the bent portion functions as the mesh outer blade 211.

[0076] Specifically, when the mesh outer blade member 30 is bent in the X direction (i.e., the second direction, more specifically, the direction that becomes the shaving direction) so as to protrude upward to form the mesh outer blade 211, the central portion of the mesh outer blade member 30 becomes the area with which the mesh inner blade 212 slides. That is, the central portion of the mesh outer blade member 30 becomes the area that is exposed to the outside when the mesh outer blade 211 is attached to the electric shaver 1, and becomes the area where the beard H (i.e., an example of body hair and hair) can be cut by the mesh outer blade 211 and the mesh inner blade 212 by making the skin contact with the area.

[0077] Thus, in this embodiment, a cuttable region 31 is formed in the central portion of the mesh outer blade member 30 , and the cuttable region 31 becomes a region capable of cutting beard H (ie, an example of body hair and hair) when the mesh outer blade 211 is mounted on the electric shaver 1 .

[0078] And, this cuttable area 31 is formed into the state of being covered with many blade holes 33 of the roughly hexagonal shape delimited by the frame strip 32. Like this, by making the shape of the blade hole 33 formed in the mesh outer blade member 30 into a roughly hexagonal shape, the situation that the introduction efficiency of the beard H (i.e., an example of body hair and hair) opposite to the blade hole 33 into the blade hole 33 is suppressed and reduces.

[0079] In this embodiment, a plurality of blade holes 33 of a substantially hexagonal shape defined by the frame strips 32 are formed in the cuttable area 31 in a row in the Y direction (i.e., the first direction) and the X direction (i.e., the second direction orthogonal to the first direction). Figure 5 As shown, the row of blade holes 33 extending roughly along the X direction (i.e., the second direction) is arranged from one end 31a to the other end 31b of the cuttable area 31 in the Y direction (i.e., the first direction). Similarly, the row of blade holes 33 extending roughly along the Y direction (i.e., the first direction) is arranged from one end 31c to the other end 31d in the X direction (i.e., the second direction) of the cuttable area 31. In this way, the cuttable area 31 is covered with many blade holes 33 in a roughly hexagonal shape defined by the frame strips 32.

[0080] In addition, in the present embodiment, the direction in which the mesh inner blade 212 moves relative to the mesh outer blade 211 when the mesh outer blade 211 is provided in the electric shaver 1 is defined as the Y direction (i.e., the first direction) of the mesh outer blade member 30. In addition, the direction in which the mesh outer blade 211 becomes the shaving direction when the mesh outer blade 211 is provided in the electric shaver 1 is defined as the X direction (i.e., the second direction) of the mesh outer blade member 30. Therefore, in the state in which the mesh outer blade 211 is provided in the electric shaver 1, the mesh outer blade 211 is formed with blade holes 33 arranged in a row in the X direction (i.e., the front-back direction, more specifically, the shaving direction) and the Y direction (i.e., the left-right direction, more specifically, the direction in which the mesh inner blade moves relative to the mesh outer blade).

[0081] Furthermore, in the present embodiment, each blade hole 33 is defined in a substantially hexagonal shape by a pair of first frame bars 321 , a pair of second frame bars 322 , and a pair of third frame bars 323 .

[0082] Specifically, if Figure 6 As shown, around a blade hole 33, a pair of first frame strips 321 extending along the Y direction (i.e., the first direction) are arranged in a state separated in the X direction (i.e., the second direction). In addition, a second frame strip 322 inclined relative to the X direction (i.e., the second direction) is continuously arranged with the end portion of the first frame strip 321 located at the side of one end 31c in the X direction (i.e., the second direction) on the side of one end 31a in the Y direction (i.e., the first direction). In addition, another second frame strip 322 inclined relative to the X direction (i.e., the second direction) is continuously arranged with the end portion of the first frame strip 321 located at the side of the other end 31d in the X direction (i.e., the second direction) on the side of the other end 31b in the Y direction (i.e., the first direction).

[0083] Furthermore, a third frame strip 323 inclined to the side opposite to the second frame strip 322 with respect to the X direction (i.e., the second direction) is continuously provided with an end portion on the side of the other end 31b in the Y direction (i.e., the first direction) of the first frame strip 321 located on the side of one end 31c in the X direction (i.e., the second direction) and an end portion of another second frame strip 322. In addition, another third frame strip 323 inclined to the side opposite to the second frame strip 322 with respect to the X direction (i.e., the second direction) is continuously provided with an end portion on the side of one end 31a in the Y direction (i.e., the first direction) of the first frame strip 321 located on the side of the other end 31d in the X direction (i.e., the second direction) and an end portion of a second frame strip 322.

[0084] In this way, the blade hole 33 formed in a hexagonal shape that is point-symmetrical with respect to the center of the blade hole 33 is defined by the pair of first frame bars 321 , the pair of second frame bars 322 , and the pair of third frame bars 323 .

[0085] Thus, in this embodiment, the frame bar 32 has a first frame bar 321 extending approximately parallel to the Y direction (i.e., the first direction), a second frame bar 322 connected to the first frame bar 321, and a third frame bar 323 connected to the second frame bar 322. The first frame bar 321, the second frame bar 322, and the third frame bar 323 define a blade hole 33 of an approximately hexagonal shape.

[0086] Furthermore, if the blade hole 33 is set to such a shape, a corner 33a is formed at the end of the blade hole 33 in the Y direction (i.e., the first direction), and the corner 33a is defined by the connecting part of the second frame bar 322 and the third frame bar 323, and the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 can be maintained in a state where movement is suppressed.

[0087] If such a corner portion 33a is provided at the end portion in the Y direction (i.e., the first direction) in which the mesh inner blade 212 moves relative to each other, the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 can be cut by the mesh inner blade 212 moving along the Y direction (i.e., the first direction) in a state where the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 is moved in a manner of being inserted into the corner portion 33a. Furthermore, if the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 is inserted into the corner portion 33a and cut by the mesh inner blade 212 moving along the Y direction (i.e., the first direction), the beard H (i.e., an example of body hair and hair) can be prevented from sliding in the X direction (the second direction) (i.e., sliding in the horizontal direction) and falling down, and the beard H (i.e., an example of body hair and hair) can be cut shorter more reliably. Furthermore, if the lateral sliding of the beard H (ie, an example of body hair and hair) can be suppressed and the beard H (ie, an example of body hair and hair) can be cut shorter more reliably, irritation to the skin when using the electric shaver 1 can also be reduced.

[0088] In this embodiment, the length of the first frame strip 321 is longer than the length of the second frame strip 322 and the length of the third frame strip 323. Thus, the blade hole 33 is a hexagonal shape flattened in the X direction (ie, the second direction).

[0089] In addition, in the present embodiment, the length of the second frame strip 322 is longer than the length of the third frame strip 323, and the inclination angle of the second frame strip 322 relative to the X direction (i.e., the second direction) is larger than the inclination angle of the third frame strip 323 relative to the X direction (i.e., the second direction). In this way, the corner 33a formed on the side of one end 31a in the Y direction (i.e., the first direction) and the corner 33a on the side of the other end 31b in the Y direction (i.e., the first direction) of one blade hole 33 are formed at positions offset in the X direction (i.e., the second direction). At this time, the offset amount of the two corners 33a in the X direction (i.e., the second direction) is made less than 1 / 4 of the length of the blade hole 33 in the X direction (i.e., the second direction).

[0090] Furthermore, the angle of the connecting portion of the second frame strip 322 and the third frame strip 323, that is, the angle of the corner 33a is set to be greater than 135 degrees and less than 160 degrees. In this way, the corner 33a formed as an obtuse angle can suppress the lateral sliding of the beard H (i.e., an example of body hair and hair), and can also reduce the irritation to the skin when using the electric shaver 1.

[0091] In addition, in the present embodiment, the periphery of the blade hole 33 when viewed along the Z direction does not form an edge. That is, the corners (including the corners 33a) formed at the connecting portion of each frame strip are made into an R shape or a shape close thereto. In this way, the irritation to the skin when the electric shaver 1 is used can be further reduced.

[0092] Furthermore, in the present embodiment, the plurality of blade holes 33 formed in the cuttable region 31 are made to have substantially the same shape. In this way, the introduction efficiency of the beard H (i.e., an example of body hair and hair) into all the blade holes 33 is made substantially the same, and the introduction efficiency of the beard H (i.e., an example of body hair and hair) does not vary due to the position difference of the cuttable region 31. In other words, the introduction efficiency of the beard H (i.e., an example of body hair and hair) in the cuttable region 31 is made more uniform.

[0093] At this time, the thickness of the frame strip 32 defining the blade hole 33 is also made to be approximately the same. In the present embodiment, the thickness of the frame strip 32 is made to be about 0.2 mm. In this way, the strength of the mesh outer blade member 30 can be ensured, and the opening ratio of the blade hole 33 formed in the cuttable area 31 can be further improved. That is, the efficiency of introducing the beard H (i.e., an example of body hair and hair) and the strength of the mesh outer blade member 30 can be achieved.

[0094] In this embodiment, the blade holes 33 are arranged in a row in the X direction (i.e., the second direction) with adjacent blade holes in the X direction (i.e., the second direction) being at positions offset in the Y direction (i.e., the first direction). In other words, a row extending in the X direction is formed.

[0095] Specifically, two adjacent blade holes 33 in the X direction (i.e., the second direction) are formed in such a manner that the blade hole 33 located at one end 31c side in the X direction (i.e., the second direction) is offset toward the other end 31b side in the Y direction (i.e., the first direction) relative to the blade hole 33 located at the other end 31d side in the X direction (i.e., the second direction). Thus, in the present embodiment, the blade hole 33 on one side (more specifically, on the one end 31c side) in the X direction (i.e., the second direction) is offset toward the same direction (more specifically, on the other end 31b side) in the Y direction (i.e., the first direction) relative to the blade hole 33 on the other side (more specifically, on the other end 31d side) in the X direction (i.e., the second direction).

[0096] Furthermore, in the present embodiment, the offset amounts of the blade holes 33 adjacent to each other in the X direction (ie, the second direction) in the Y direction (ie, the first direction) are set to be substantially the same amount (ie, substantially the same amount).

[0097] Therefore, there is a blade hole 33 at a position which is offset by approximately the same amount (i.e. approximately the same amount) toward the one end 31a side in the Y direction (i.e. the first direction) as it moves from the one end 31c side in the X direction (i.e. the second direction) toward the other end 31d side, so that the row of blade holes 33 formed in a manner approximately along the X direction (i.e. the second direction) becomes a row inclined toward the other end 31d side in the X direction (i.e. the second direction) and toward the one end 31a side in the Y direction (i.e. the first direction).

[0098] In addition, in the present embodiment, the blade holes 33 are formed in a row in the Y direction (i.e., the first direction) with adjacent blade holes in the Y direction (i.e., the first direction) being at positions offset in the X direction (i.e., the second direction). In other words, a row extending in the Y direction is formed.

[0099] Specifically, two adjacent blade holes 33 in the Y direction (i.e., the first direction) are formed in such a manner that the blade hole 33 located at one end 31a side in the Y direction (i.e., the first direction) is offset toward one end 31c side in the X direction (i.e., the second direction) relative to the blade hole 33 located at the other end 31b side in the Y direction (i.e., the first direction). Thus, in the present embodiment, the blade hole 33 on one side (more specifically, the one end 31a side) in the Y direction (i.e., the first direction) is offset toward the same direction (more specifically, the one end 31c side) in the X direction (i.e., the second direction) relative to the blade hole 33 on the other side (more specifically, the other end 31b side) in the Y direction (i.e., the first direction).

[0100] Furthermore, in the present embodiment, the offset amounts of the blade holes 33 adjacent to each other in the Y direction (ie, the first direction) in the X direction (ie, the second direction) are set to be substantially the same.

[0101] Therefore, there is a blade hole 33 at a position which is offset by approximately the same amount toward the other end 31d in the X direction (i.e., the second direction) as it moves from the one end 31a in the Y direction (i.e., the first direction) toward the other end 31b, so that the row of blade holes 33 formed in a manner approximately along the Y direction (i.e., the first direction) becomes a row inclined toward the other end 31b in the Y direction (i.e., the first direction) and toward the other end 31d in the X direction (i.e., the second direction).

[0102] Thus, in the present embodiment, the plurality of blade holes 33 are formed in the cuttable region 31 in a regularly arranged state so as to form rows intersecting the Y direction (ie, the first direction) and the X direction (ie, the second direction).

[0103] Thus, it is possible to suppress the situation that the introduction efficiency of the beard H (ie, an example of body hair and hair) is biased due to the position difference of the cuttable area 31. In addition, the position of the blade hole 33 can be easily set, and the mesh outer blade member 30 can be manufactured more easily.

[0104] In addition, if a plurality of blade holes 33 are regularly arranged in a row that intersects the Y direction (i.e., the first direction) and the X direction (i.e., the second direction), the corners 33a of the blade holes 33 adjacent to each other in the X direction (i.e., the second direction) are offset in the Y direction (i.e., the first direction).

[0105] In this way, if the corners 33a formed in the adjacent blade holes 33 in the X direction (i.e., the second direction) are staggered in the Y direction (i.e., the first direction), it is possible to prevent the beards H (i.e., an example of body hair and hair) introduced into the adjacent blade holes 33 in the X direction (i.e., the second direction) from being cut at the same time. As a result, the load on the mesh inner blades 212 can be reduced, and the irritation to the skin when the electric shaver 1 is used can also be reduced.

[0106] Furthermore, if the plurality of blade holes 33 are regularly arranged in rows that intersect the Y direction (i.e., the first direction) and the X direction (i.e., the second direction), the first frame strips 321 that define the blade holes 33 are offset in the X direction (i.e., the second direction).

[0107] That is, when one of the adjacent blade holes 33 in the Y direction (i.e., the first direction) (more specifically, the blade hole 33 on the one end 31a side) is set as the first blade hole 33C and the other (more specifically, the blade hole 33 on the other end 31b side) is set as the second blade hole 33D, the first frame strip 321 defining the first blade hole 33C is offset toward the one end 31c side in the X direction (i.e., the second direction) relative to the first frame strip 321 defining the second blade hole 33D.

[0108] In this way, it is possible to further reduce the variation in the ease of introduction of the beard H (ie, an example of body hair and hair) into the blade hole 33 due to the difference in length.

[0109] For example, if the first frame strip 321 is arranged in a straight line along the Y direction (i.e., the first direction), when a beard H (i.e., an example of body hair and hair) of a certain length is difficult to introduce into the blade hole 33, all the blade holes 33 arranged in the Y direction (i.e., the first direction) become blade holes 33 into which it is difficult to introduce the beard H (i.e., an example of body hair and hair) of this length.

[0110] In contrast, if the first frame strips 321 adjacent in the Y direction (i.e., the first direction) are offset in the X direction (i.e., the second direction), even if a beard H (i.e., an example of body hair and hair) of a certain length is difficult to introduce into one blade hole 33, the other blade hole 33 located at the offset position can be made into a blade hole 33 that easily allows the beard H (i.e., an example of body hair and hair) of the length to be introduced. In addition, even if a beard H (i.e., an example of body hair and hair) of another length is difficult to introduce into the other blade hole 33, the one blade hole 33 located at the offset position can be made into a blade hole 33 that easily allows the beard H (i.e., an example of body hair and hair) of another length to be introduced into the other blade hole 33.

[0111] In this way, if the first frame strips 321 are not arranged in a straight line along the Y direction (i.e., the first direction), the deviation of the ease of introduction of the beard H (i.e., an example of body hair and hair) into the blade hole 33 caused by the difference in its length can be further reduced. That is, the beard H (i.e., an example of body hair and hair) of various lengths can be more efficiently introduced into the blade hole 33. As a result, the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0112] In addition, the first frame bars 321 defining the blade holes 33 are also offset in the Y direction (ie, the first direction).

[0113] That is, the first frame strip 321 defining one of the adjacent blade holes 33 in the X direction (i.e., the second direction) (more specifically, the blade hole 33 at one end 31c) is offset toward the other end 31b in the Y direction (i.e., the first direction) relative to the first frame strip 321 defining the other one (more specifically, the blade hole 33 at the other end 31d).

[0114] In this way, it is also possible to further reduce the variation in the ease of introduction of the beard H (ie, an example of body hair and hair) into the blade hole 33 due to the difference in length.

[0115] For example, if the first frame strips 321 are arranged at the same position in the X direction (i.e., the second direction), when a beard H (i.e., an example of body hair and hair) of a certain length is difficult to be introduced into the blade hole 33, the beard H (i.e., an example of body hair and hair) of the length is also difficult to be introduced into all the blade holes 33 arranged along the X direction (i.e., the second direction). That is, when moving along the X direction (i.e., the second direction), there are blade holes 33 of the same shape at the same position in the Y direction (i.e., the first direction), so the beard H is sometimes not introduced into any blade hole 33 and becomes a missed beard H (i.e., an example of body hair and hair).

[0116] In contrast, if the first frame strips 321 adjacent to each other in the X direction (i.e., the second direction) are staggered in the Y direction (i.e., the first direction), the blade holes 33 of the same shape will not exist at the same position in the Y direction (i.e., the first direction) when moving along the X direction (i.e., the second direction). That is, since there are various forms of introduction holes (more specifically, blade holes 33) in the X direction (i.e., the second direction), the possibility of introduction into any hole shape can be increased.

[0117] In this way, if the first frame strips 321 are not arranged at the same position in the X direction (i.e., the second direction), the deviation in the ease of introduction of the beard H (i.e., an example of body hair and hair) into the blade hole 33 caused by the difference in length can be further reduced. That is, the beard H (i.e., an example of body hair and hair) of various lengths can be more efficiently introduced into the blade hole 33. As a result, the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0118] Furthermore, in this embodiment, at any position between one end 31a and the other end 31b in the cuttable area 31 in the Y direction (i.e., the first direction), there is a blade hole 33 within a range of a distance equal to five rows of blade holes moved along the X direction (i.e., the second direction).

[0119] Thus, when the electric shaver 1 is moved along the X direction (i.e., the second direction) while the skin is in contact with the outer surface of the mesh outer blade 211, the skin in contact with all positions between the one end 31a and the other end 31b in the Y direction (i.e., the first direction) in the cuttable area 31 can be made to face the blade hole 33 within a range of a distance equal to the distance of five rows of blade holes. That is, when the electric shaver 1 is moved along the X direction (i.e., the second direction) while the skin is in contact with the outer surface of the mesh outer blade 211, there will be no portion that is in contact with only the frame bar 32 that defines the blade hole 33.

[0120] In this way, no matter where the beard H (i.e., an example of body hair and hair) is present on the skin in contact with the outer surface of the mesh outer blade 211, the beard H (i.e., an example of body hair and hair) can be made to face the blade hole 33 within a range of a distance until the electric shaver 1 is moved along the X direction (i.e., the second direction) by five rows of blade holes. That is, the beard H (i.e., an example of body hair and hair) whose introduction into the blade hole 33 is blocked by the frame bar 32 can be eliminated.

[0121] Therefore, when the electric shaver 1 having the mesh outer blade 211 formed by using such a mesh outer blade member 30 is used, all the beards H (i.e., an example of body hair and hair) existing on the skin in contact with the outer surface of the mesh outer blade 211 are given the opportunity to be introduced into the blade holes 33 while the electric shaver 1 is moved along the X direction (i.e., the second direction) by a distance corresponding to five rows of blade holes. As a result, the beards H (i.e., an example of body hair and hair) can be shaved more efficiently.

[0122] In addition, the area of ​​the five rows of blade holes along the X direction (i.e., the second direction) is generally approximately the same as the area where the skin contacts the mesh outer blade when the skin contacts the mesh outer blade, which is formed by bending a long plate-shaped mesh outer blade member along the short side direction.

[0123] Therefore, in this embodiment, within the range of five rows of blade holes that are usually in contact with the skin, when viewed along the X direction (i.e., the second direction), blade holes 33 exist at all positions between one end 31a and the other end 31b in the Y direction (i.e., the first direction).

[0124] Therefore, if an electric shaver 1 is used that has a mesh outer blade 211 formed by bending the mesh outer blade component 30 of the present embodiment along the short side direction, by moving the electric shaver 1 in the X direction (i.e., the second direction) by a stroke (more specifically, the amount of five rows of blade holes) while the skin is in contact with the mesh outer blade 211, all the skin in contact with the mesh outer blade 211 can be made to face the blade holes 33.

[0125] As described above, by using the mesh outer blade member 30 of the present embodiment, it is possible to form the mesh outer blade 211 that can more efficiently shave the beard H (ie, an example of body hair and hair).

[0126] Furthermore, in the present embodiment, at any position between one end 31a and the other end 31b in the cuttable area 31 in the Y direction (i.e., the first direction), the blade holes 33 exist in a state capable of introducing beard H (i.e., an example of body hair and hair) within a range of a distance up to the amount of five rows of blade holes moved along the X direction (i.e., the second direction).

[0127] Specifically, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state where the skin is in contact with the outer surface of the mesh outer blade 211, the skin in contact at all positions between one end 31a and the other end 31b in the Y direction (i.e., the first direction) in the cuttable area 31 is opposed to the blade hole 33 in a state where there is an opening (more specifically, an opening having a region area greater than the cross-sectional area of ​​the beard) of a degree that allows the beard H (i.e., an example of body hair and hair) to be introduced. At this time, at all positions between one end 31a and the other end 31b in the Y direction (i.e., the first direction), there are blade holes 33 with a width (i.e., the length in the X direction) greater than 0.12 mm, which is the average thickness of the beard H (i.e., an example of body hair and hair), within the range of five rows of blade holes.

[0128] In this embodiment, if Figure 6 As shown, when any blade hole among the multiple blade holes 33 formed in the cuttable area 31 is set as the reference blade hole 33A, the reference blade hole 33A and the blade hole 33B overlap when observed along the X direction (i.e., the second direction), and the blade hole 33B is adjacent to the blade hole 33 at a position moved from the reference blade hole 33A along the X direction (i.e., the second direction) in the Y direction (i.e., the first direction) by the amount of five rows of blade holes.

[0129] In this way, by staggering the position of the blade hole 33 little by little in the Y direction, at all positions between one end 31a and the other end 31b in the Y direction (i.e., the first direction), within the range of the amount of five rows of blade holes, there are blade holes 33 with an average thickness of the beard H (i.e., an example of body hair and hair), i.e., a width of more than 0.12 mm (i.e., the length in the X direction).

[0130] In this way, the skin in contact with the outer surface of the mesh outer blade 211 can be free of the beard H (i.e., an example of body hair and hair) which is opposite to the blade hole 33 but cannot be introduced into the blade hole 33 within the range of the distance until the five rows of blade holes are moved along the X direction (i.e., the second direction). In other words, the blade hole 33 which does not contribute to the introduction of the beard H (i.e., an example of body hair and hair) when the electric shaver 1 is used can be free of.

[0131] Therefore, the electric shaver 1 can be formed to be able to shave the beard H (that is, an example of body hair and hair) more effectively.

[0132] Furthermore, in the present embodiment, as described above, the frame strip 32 includes the first frame strip 321 extending substantially parallel to the Y direction (ie, the first direction).

[0133] Therefore, when the electric shaver 1 is moved along the X direction (ie, the second direction) while the skin is in contact with the outer surface of the mesh outer blade 211 , the first frame bar 321 can more reliably stand up the lying beard H (ie, an example of body hair and hair).

[0134] Furthermore, in this embodiment, if Figure 8 As shown, the thickness T1 of the first frame strip 321 is smaller than the thickness T2 of the second frame strip 322 and the thickness T3 of the third frame strip 323. Specifically, the step portion 32a is formed at the boundary between the second frame strip 322 and the third frame strip 323 and the first frame strip 321.

[0135] In this way, if the thickness of the first frame strip 321 having the function of raising the fallen beard H (i.e., an example of body hair and hair) is made smaller, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state where the skin is in contact with the outer surface of the mesh outer blade 211, the first frame strip 321 can be more easily inserted under the fallen beard H (i.e., an example of body hair and hair). As a result, the fallen beard H (i.e., an example of body hair and hair) can be raised more reliably by the first frame strip 321, so the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0136] [Function, Effect]

[0137] Hereinafter, characteristic structures of the mesh outer blade member, the mesh outer blade formed using the mesh outer blade member, and the electric shaver including the mesh outer blade and effects obtained thereby, shown in the above-described embodiment, will be described.

[0138] (Technique 1) The mesh outer blade member 30 shown in the above embodiment is a member capable of forming the mesh outer blade 211 provided in the electric shaver 1. The mesh outer blade member 30 has a cuttable region 31 capable of cutting beard H (i.e., an example of body hair and hair) when the mesh outer blade 211 is provided in the electric shaver 1.

[0139] In addition, a plurality of substantially hexagonal blade holes 33 defined by the frame strips 32 are formed in the cuttable region 31 in a row in the Y direction (ie, the first direction) and the X direction (ie, the second direction orthogonal to the first direction).

[0140] Here, the Y direction (i.e., the first direction) is the direction in which the mesh inner blade 212 moves relative to the mesh outer blade 211 when the mesh outer blade 211 is provided in the electric shaver 1. In addition, the X direction (i.e., the second direction) is the direction in which the mesh outer blade 211 is provided in the electric shaver 1 to be shaved.

[0141] Furthermore, the blade holes 33 are formed in a row in the X direction (ie, the second direction) in a state where the blade holes adjacent in the X direction (ie, the second direction) are located at positions shifted in the Y direction (ie, the first direction).

[0142] Furthermore, at any position between one end 31a and the other end 31b in the cuttable area 31 in the Y direction (ie, the first direction), there is a blade hole 33 within a range of a distance equal to five rows of blade holes shifted in the X direction (ie, the second direction).

[0143] If the mesh outer blade member 30 having such blade holes 33 is used to form the mesh outer blade 211 and the mesh outer blade 211 is provided in the electric shaver 1, the electric shaver 1 capable of shaving the beard H (ie, an example of body hair and hair) more efficiently can be obtained.

[0144] For example, if the electric shaver 1 is used, which is provided with the mesh outer blade 211 formed by using the mesh outer blade member 30 shown in the above embodiment, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state where the skin is in contact with the outer surface of the mesh outer blade 211, the skin in contact with any position between the one end 31a and the other end 31b in the Y direction (i.e., the first direction) in the cuttable area 31 is also opposed to the blade hole 33 within the range of the distance until the five rows of blade holes are moved. That is, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state where the skin is in contact with the outer surface of the mesh outer blade 211, there is no portion that is in contact with only the frame bar 32 that defines the blade hole 33.

[0145] Therefore, no matter where the beard H (i.e., an example of body hair and hair) exists on the skin in contact with the outer surface of the mesh outer blade 211, the beard H (i.e., an example of body hair and hair) can be made to face the blade hole 33 within a range of a distance until the electric shaver 1 is moved along the X direction (i.e., the second direction) by five rows of blade holes. In other words, the beard H (i.e., an example of body hair and hair) whose introduction into the blade hole 33 is blocked by the frame bar 32 can be eliminated.

[0146] In this way, when using the electric shaver 1 having the mesh outer blade 211 formed by using the mesh outer blade member 30 shown in the above embodiment, all the beards H (i.e., an example of body hair and hair) existing on the skin in contact with the outer surface of the mesh outer blade 211 are given the opportunity to be introduced into the blade hole 33 while the electric shaver 1 is moved along the X direction (i.e., the second direction) by a distance equal to five rows of blade holes.

[0147] Furthermore, since the blade hole 33 formed in the mesh outer blade member 30 shown in the above embodiment is substantially hexagonal, it is possible to suppress the situation where the introduction efficiency of the beard H (i.e., an example of body hair and hair) facing the blade hole 33 into the blade hole 33 is reduced.

[0148] Therefore, if the electric shaver 1 is provided with the mesh outer blade 211 formed using the mesh outer blade member 30 shown in the above embodiment, it is possible to shave the beard H (ie, an example of body hair and hair) more efficiently.

[0149] In this way, by using the mesh outer blade member 30 shown in the above embodiment, it is possible to form the mesh outer blade 211 that can shave the beard H (ie, an example of body hair and hair) more efficiently.

[0150] (Technique 2) Alternatively, in the above-mentioned (Technique 1), at any position between one end 31a and the other end 31b in the cuttable area 31 in the Y direction (i.e., the first direction), within the range of the distance until the amount of five rows of blade holes are moved along the X direction (i.e., the second direction), the blade holes 33 are in a state in which beards H (i.e., an example of body hair and hair) can be introduced.

[0151] For example, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state in which the skin is in contact with the outer surface of the mesh outer blade 211, the skin in contact at all positions between one end 31a and the other end 31b in the Y direction (i.e., the first direction) in the cuttable area 31 can be brought into contact with the blade hole 33 in a state in which there is an opening (more specifically, an opening having an area area larger than the cross-sectional area of ​​the beard) of a degree that allows the beard H (i.e., an example of body hair and hair) to be introduced.

[0152] In this way, it is possible to prevent the skin in contact with the outer surface of the mesh outer blade 211 from having a beard H (i.e., an example of body hair and hair) which is opposite to the blade hole 33 but cannot be introduced into the blade hole 33 within a range of a distance of five rows of blade holes moved along the X direction (i.e., the second direction). In other words, it is possible to more reliably prevent the presence of the blade hole 33 which does not contribute to the introduction of the beard H (i.e., an example of body hair and hair) when the electric shaver 1 is used.

[0153] As a result, the electric shaver 1 can more effectively shave the beard H (ie, an example of body hair and hair).

[0154] (Technique 3) In addition, in the above-mentioned (Technique 1) or (Technique 2), the plurality of blade holes 33 formed in the cuttable region 31 may have substantially the same shape.

[0155] In this way, the introduction efficiency of the beard H (i.e., an example of body hair and hair) into all the blade holes 33 can be made substantially the same. Therefore, it is possible to suppress the situation where the introduction efficiency of the beard H (i.e., an example of body hair and hair) is biased due to the position difference of the cuttable area 31. That is, the introduction efficiency of the beard H (i.e., an example of body hair and hair) in the cuttable area 31 can be made more uniform.

[0156] (Technique 4) In addition, it can also be that in any of the above-mentioned (Technique 1) to (Technique 3), the blade hole 33 on one side in the X direction (i.e., the second direction) is offset in the same direction in the Y direction (i.e., the first direction) relative to the blade hole 33 on the other side in the X direction (i.e., the second direction).

[0157] In this way, a plurality of blade holes 33 can be arranged regularly, so it is possible to suppress the situation in which the introduction efficiency of the beard H (i.e., an example of body hair and hair) is biased due to the position difference of the cuttable area 31. In addition, if a plurality of blade holes 33 are arranged regularly, the position setting of the blade holes 33 becomes easy, and it is possible to manufacture more easily.

[0158] (Technique 5) In addition, in any of the above-mentioned (Technique 1) to (Technique 4), the offset amounts of the adjacent blade holes 33 in the X direction (ie, the second direction) in the Y direction (ie, the first direction) may be substantially the same.

[0159] In this way, the plurality of blade holes 33 can be arranged more regularly, so it is possible to suppress the situation in which the introduction efficiency of the beard H (i.e., an example of body hair and hair) is biased due to the position difference of the cuttable area 31. In addition, if the plurality of blade holes 33 are arranged regularly, the position setting of the blade holes 33 becomes easy, and it is possible to manufacture more easily.

[0160] (Technique 6) In addition, it can also be that, in any of the above-mentioned (Technique 1) to (Technique 5), when any blade hole among the multiple blade holes 33 formed in the cuttable area 31 is set as the reference blade hole 33A, the reference blade hole 33A and the blade hole 33B overlap when observed along the X direction (i.e., the second direction), and the blade hole 33B is adjacent to the blade hole 33 at a position that is moved five columns of blade holes along the X direction (i.e., the second direction) from the reference blade hole 33A in the Y direction (i.e., the first direction).

[0161] In this way, a plurality of blade holes 33 can be arranged regularly, so it is possible to suppress the situation in which the introduction efficiency of the beard H (i.e., an example of body hair and hair) is biased due to the position difference of the cuttable area 31. In addition, if a plurality of blade holes 33 are arranged regularly, the position setting of the blade holes 33 becomes easy, and it is possible to manufacture more easily.

[0162] (Technique 7) In any one of the above-mentioned (Technique 1) to (Technique 6), the frame strip 32 may include a first frame strip 321 extending substantially parallel to the Y direction (ie, the first direction).

[0163] In this way, when the electric shaver 1 is moved along the X direction (i.e., the second direction) while the skin is in contact with the outer surface of the mesh outer blade 211, the first frame bar 321 can be used to more reliably stand up the fallen beard H (i.e., an example of body hair and hair), so that the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0164] (Technique 8) In addition, in the above (Technique 7), when one of the adjacent blade holes 33 in the Y direction (i.e., the first direction) is set as the first blade hole 33C and the other is set as the second blade hole 33D, the first frame strip 321 defining the first blade hole 33C and the first frame strip 321 defining the second blade hole 33D are offset in the X direction (i.e., the second direction).

[0165] In this way, it is possible to further reduce the variation in the ease of introduction of the beard H (ie, an example of body hair and hair) into the blade hole 33 due to the difference in length.

[0166] For example, if the first frame strip 321 is arranged in a straight line along the Y direction (i.e., the first direction), when a beard H (i.e., an example of body hair and hair) of a certain length is difficult to introduce into the blade hole 33, all the blade holes 33 arranged in the Y direction (i.e., the first direction) become blade holes 33 into which it is difficult to introduce the beard H (i.e., an example of body hair and hair) of this length.

[0167] In contrast, if the first frame strips 321 adjacent in the Y direction (i.e., the first direction) are offset in the X direction (i.e., the second direction), even if a beard H (i.e., an example of body hair and hair) of a certain length is difficult to introduce into one blade hole 33, the other blade hole 33 located at the offset position can be made into a blade hole 33 that easily allows the beard H (i.e., an example of body hair and hair) of the length to be introduced. In addition, even if a beard H (i.e., an example of body hair and hair) of another length is difficult to introduce into the other blade hole 33, the one blade hole 33 located at the offset position can be made into a blade hole 33 that easily allows the beard H (i.e., an example of body hair and hair) of another length to be introduced into the other blade hole 33.

[0168] In this way, if the first frame strips 321 are not arranged in a straight line along the Y direction (i.e., the first direction), the deviation of the ease of introduction of the beard H (i.e., an example of body hair and hair) into the blade hole 33 caused by the difference in its length can be further reduced. That is, the beard H (i.e., an example of body hair and hair) of various lengths can be more efficiently introduced into the blade hole 33. As a result, the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0169] (Technique 9) In addition, in the above (Technique 7) or (Technique 8), the frame strip 32 may include a second frame strip 322 connected to the first frame strip 321 and a third frame strip 323 connected to the second frame strip 322. In addition, the blade hole 33 may be formed with a corner 33a, which is formed at the end of the blade hole 33 in the Y direction (i.e., the first direction), and can keep the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 in a state where movement is suppressed. In addition, the corner 33a may be formed at the connecting portion of the second frame strip 322 and the third frame strip 323.

[0170] In this way, the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 can be cut by the mesh inner blade 212 moving along the Y direction (i.e., the first direction) in a state where the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 is moved in a manner of being stuffed into the corner 33a. In this way, if the beard H (i.e., an example of body hair and hair) introduced into the blade hole 33 is stuffed into the corner 33a and is cut by the mesh inner blade 212 moving along the Y direction (i.e., the first direction), it is possible to suppress the beard H (i.e., an example of body hair and hair) from sliding along the X direction (i.e., the second direction) (i.e., sliding laterally) and falling down, and the beard H (i.e., an example of body hair and hair) can be cut shorter more reliably.

[0171] Furthermore, if the lateral sliding of the beard H (ie, an example of body hair and hair) can be suppressed and the beard H (ie, an example of body hair and hair) can be cut shorter more reliably, the irritation to the skin when using the electric shaver 1 can also be reduced.

[0172] (Technique 10) In addition, in the above (Technique 9), the corners 33a formed in the blade holes 33 adjacent to each other in the X direction (ie, the second direction) may be offset in the Y direction (ie, the first direction).

[0173] Like this, can suppress the situation that the beard H (i.e. body hair and hair) introduced into the adjacent blade hole 33 on the X direction (i.e. second direction) is cut at the same time, thereby can reduce the load of mesh inner blade 212, and can also reduce the stimulation brought to the skin when using electric razor 1.

[0174] (Technique 11) In addition, in the above (Technique 9) or (Technique 10), the thickness T1 of the first frame strip 321 may be smaller than the thickness T2 of the second frame strip 322 and the thickness T3 of the third frame strip 323.

[0175] In this way, when the electric shaver 1 is moved along the X direction (i.e., the second direction) in a state where the skin is in contact with the outer surface of the mesh outer blade 211, the first frame bar 321 can be more easily inserted into the lower side of the fallen beard H (i.e., an example of body hair and hair). As a result, the fallen beard H (i.e., an example of body hair and hair) can be more reliably erected by the first frame bar 321, so the beard H (i.e., an example of body hair and hair) can be shaved more effectively.

[0176] (Technique 12) The mesh outer blade 211 shown in the above embodiment is formed using the mesh outer blade member 30 disclosed in any one of the above (Technique 1) to (Technique 11).

[0177] If the net outer blade 211 is formed using such a net outer blade member 30, the net outer blade 211 can be formed to be able to shave the beard H (ie, an example of body hair and hair) more efficiently.

[0178] (Technique 13) The electric shaver 1 shown in the above embodiment includes the mesh outer blade 211 disclosed in the above (Technique 12).

[0179] In this way, it is possible to obtain the electric shaver 1 which can shave hair more efficiently.
