DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0013] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0014] In addition, when describing the electric razor in the following embodiments, the direction in which multiple blade blocks are arranged side by side will be described as the X direction (front-to-back direction: shaving direction), and the direction in which each blade block extends will be described as the Y direction (left-to-right direction: direction in which the inner net blade moves relative to the outer net blade).

[0015] The vertical direction in the state where the head cover (electric shaver) is arranged so that the skin contact surface faces upward is described as the Z direction (vertical direction). In this embodiment, the skin contact surface of the blade unit is composed of the surfaces (outer surfaces) of the outer blades of the multiple blade blocks, and as a whole, it is a surface that can be approximated by a curved surface that is convex outward. Therefore, in the following embodiment, the state where the most outwardly protruding point of the curved surface approximating the skin contact surface of the blade unit is located at the top, and the tangent plane at the most outwardly protruding point of the curved surface approximating the skin contact surface of the blade unit is a horizontal plane is defined as the state where the head part (main body part) is arranged so that the skin contact surface faces upward.

[0016] In the following embodiments, the side of the electric shaver on which the power switch is provided is defined as the front in the X direction.

[0017] In addition, when describing the net outer blade member in the following embodiments, the short side direction of the net outer blade member is the X direction (second direction: shaving direction), the long side direction of the net outer blade member is the Y direction (first direction: direction in which the net inner blade moves relative to the net outer blade), and the thickness direction of the net outer blade member is the Z direction (plate thickness direction). In the following embodiments, the X direction of the net outer blade member coincides with the X direction of the electric razor when the net outer blade is attached to the electric razor, and the Y direction of the net outer blade member coincides with the Y direction of the electric razor when the net outer blade is attached to the electric razor.

[0018] (Embodiment) First, the configuration of an electric shaver 1 will be described with reference to FIGS.

[0019] As shown in Figures 1 and 2, the electric razor 1 in this embodiment comprises a razor body 10 and a blade unit 20 held on the razor body 10 with the skin contact surface (the surface of the outer blade of each blade block described below) 20a exposed.

[0020] Razor body 10 includes grip portion 11 that can be held by hand, and head portion 12 that is supported by grip portion 11. In this embodiment, head portion 12 is supported by grip portion 11 in a state in which it is tilted upward and forward with the extension direction of grip portion 11 substantially aligned with the up-down direction.

[0021] The head portion 12 can be configured to swing in the Y direction relative to the grip portion 11 around a shaft portion (not shown) extending in the X direction as an axis. The head portion 12 can also be configured to swing in the X direction relative to the grip portion 11 around a shaft portion (not shown) extending in the Y direction as an axis. Furthermore, the head portion 12 can be configured to float in the Z direction relative to the grip portion 11.

[0022] It is also possible to combine these swinging and floating mechanisms appropriately. For example, it is possible to configure the head unit 12 so that it can swing in the X and Y directions relative to the grip unit 11, while also floating in the Z direction relative to the grip unit 11.

[0023] It is also possible to configure the head portion 12 so that it does not sway or float relative to the grip portion 11. It is also possible to configure the head portion 12 so that it is not inclined relative to the grip portion 11.

[0024] The grip portion 11 includes a main housing 111, and a cavity is formed inside the main housing 111. Various electrical components such as a rechargeable battery are housed inside the cavity formed inside the main housing 111.

[0025] Further, a push-type power switch 111a for operating (turning the power on and off) the electric shaver 1 is formed on the main body housing 111. Note that, although a push-type switch is exemplified as the power switch 111a in this embodiment, a slide type or other switch may be used as long as it is a switch that can turn the power on and off.

[0026] In this embodiment, the power switch 111a is formed on the front surface of the main body housing 111, i.e., the front surface (front face) of the electric shaver 1. The front surface of the electric shaver 1 refers to the surface facing the user when the user holds the grip portion 11 of the electric shaver 1 during normal use.

[0027] Also, it is possible to provide a trimmer unit at the rear of the main body housing 111 (at the rear of the electric shaver 1).

[0028] The head unit 12 includes a head unit body 121 attached to the grip unit 11, and a head cover 122 removably attached to the head unit body 121. In this embodiment, the head cover 122 and the head unit body 121 can be released from each other by retracting release buttons 121a provided on both the left and right ends of the head unit body 121 inward.

[0029] A drive mechanism is housed in the head body 121. This drive mechanism has a plurality of drive culms 13, which are housed in the head body 121 in a state in which the drive culms 13 protrude upward from the head body 121. As such a drive mechanism, for example, a conventionally known drive mechanism such as a vibration type linear actuator or a drive mechanism consisting of a rotary motor and a conversion mechanism for converting rotary motion into reciprocating linear motion can be used.

[0030] The blade unit may be the blade unit 20 shown in Fig. 2, or the blade unit 20 shown in Fig. 3 and Fig. 4. Here, the blade unit 20 shown in Fig. 2 includes three blade blocks and an outer blade case 23, and the three blade blocks are arranged in the X direction with their longitudinal directions aligned with the Y direction. On the other hand, the blade unit 20 shown in Fig. 3 and Fig. 4 includes six blade blocks and an outer blade case 23, and the six blade blocks are arranged in the X direction with their longitudinal directions aligned with the Y direction.

[0031] Thus, in this embodiment, each blade block has a predetermined length and width, and these blade blocks are arranged with their length direction roughly aligned with the Y direction (first direction: left-right direction) of the electric razor 1, and their width direction roughly aligned with the X direction (second direction: front-back direction: shaving direction) of the electric razor 1.

[0032] In the blade unit 20 shown in Fig. 2, the three blade blocks are composed of two net blade blocks 21 and one slit blade block 22. On the other hand, the blade unit 20 shown in Figs. 3 and 4 is composed of four net blade blocks 21 and two slit blade blocks 22.

[0033] The net blade block 21 mainly has a function of cutting off fallen hairs (body hair: hair) H and short, standing hairs (body hair: hair) H. The slit blade block 22 mainly has a function of cutting off thin, long hairs (body hair: hair) H.

[0034] In the blade unit 20 shown in Fig. 2, one slit blade block 22 is disposed in the center in the X direction, and two net blade blocks 21 are disposed on both sides of the slit blade block 22. In the blade unit 20 shown in Figs. 3 and 4, two net blade blocks 21 are disposed in the center in the X direction, and two slit blade blocks 22 are disposed on both sides of the central net blade block 21. The remaining two net blade blocks 21 are disposed on both sides of the slit blade block 22.

[0035] As shown in Fig. 2 to Fig. 4, the net blade block 21 includes a net outer blade 211 and a net inner blade 212. In this embodiment, the net outer blade 211 is curved in an inverted U shape so that the upper side is convex when viewed from the side (as viewed along the Y direction). Note that it is possible to form each net outer blade 211 so that all the radii of curvature (radii of curvature of the parts curved in an inverted U shape) are substantially the same, or it is possible to form at least one net outer blade 211 so that the radius of curvature is different.

[0036] Furthermore, the net outer blade 211 is formed to be slightly curved in the Y direction (outer blade length direction) so that the upper side is convex when viewed from the front (when viewed along the X direction). This net outer blade 211 is formed with a large number of blade holes 33 of approximately hexagonal shape arranged in a line. It is also possible to configure the net outer blade 211 so that it is not curved so that the upper side is convex when viewed from the front. For example, it is possible to configure the top of the net outer blade 211 to be a straight line extending in the Y direction (outer blade length direction) when viewed from the front (when viewed along the X direction).

[0037] The net inner blade 212 has an inverted U-shape that follows the curved shape of the net outer blade 211, and is disposed inside the net outer blade 211 (below the net outer blade 211: the side opposite to the side of the net outer blade 211 that contacts the skin). This net inner blade 212 is detachably attached to one of the multiple driving culms 13. When the electric shaver 1 is turned on and the driving culm 13 is driven with the net inner blade 212 attached to the driving culm 13 and disposed inside the net outer blade 211, the net inner blade 212 is displaced relative to the net outer blade 211 while sliding against the inner surface of the net outer blade 211 (relative movement: reciprocating in the Y direction).

[0038] 4, the slit blade block 22 includes an outer slit blade 221 and an inner slit blade 222. In this embodiment, the outer slit blade 221 is bent into an inverted U shape so that the upper side is convex when viewed from the side (as viewed along the Y direction).

[0039] Furthermore, the slit outer blade 221 is formed to be slightly curved along the Y direction (outer blade length direction) so that the upper side is convex when viewed from the front (when viewed along the X direction). In addition, in this slit outer blade 221, a plurality of slit-shaped blade holes extending in the X direction are formed so as to be aligned in a state spaced apart in the Y direction. It is also possible to configure the slit outer blade 221 so that the upper side is not curved so as to be convex when viewed from the front. For example, it is possible to configure the apex of the slit outer blade 221 to be a straight line extending in the Y direction (outer blade length direction) when viewed from the front (when viewed along the X direction). In other words, it is possible to form the slit outer blade 221 so that the top surface of the slit outer blade 221 is a flat surface.

[0040] As shown in FIG. 4, the slit inner blade 222 has an inverted U-shape that follows the curved shape of the slit outer blade 221, and is disposed inside the slit outer blade 221 (below the slit outer blade 221: opposite to the side of the slit outer blade 221 that contacts the skin). This slit inner blade 222 is detachably attached to one of the driving culms 13 (a driving culm 13 other than the driving culm to which the net inner blade 212 is attached) among the multiple driving culms 13. When the electric shaver 1 is turned on to drive the driving culm 13 while the slit inner blade 222 is attached to the driving culm 13 and disposed inside the slit outer blade 221, the slit inner blade 222 is displaced relative to the slit outer blade 221 (relative movement: reciprocating in the Y direction) while sliding against the inner surface of the slit outer blade 221.

[0041] As described above, the electric shaver 1 according to this embodiment has the form of a reciprocating electric shaver in which the net inner blade 212 and the slit inner blade 222 are reciprocated relative to the net outer blade 211 and the slit outer blade 221.

[0042] 2, the members of the three blade blocks, excluding the two net inner blades 212, are attached to the substantially frame-shaped outer blade case 23. At this time, each member may be detachably attached to the outer blade case 23, or may be attached to the outer blade case 23 in a state where it cannot be detached.

[0043] In addition, the two net blade blocks 21 and one slit blade block 22 are attached to the outer blade case 23 in a state in which they can float in the Z direction (up and down direction). This allows each blade block to float separately and independently with respect to the head part (main body part) 12 when the head cover 122 with the outer blade cassette 200 attached thereto is attached to the head part main body 121. This allows the outer blade (skin contact surface 20a of the blade unit 20) to be more reliably aligned with the shape of the skin, and allows whiskers (body hair: hair) H to be cut more reliably.

[0044] At least one of the plurality of blade blocks may be held in the head portion (main body portion) 12 in a state in which it cannot float.

[0045] In this embodiment, as shown in Fig. 2, two net outer blades 211 are attached to the outer blade case 23 without the net inner blade 212 arranged on the inside, and one slit outer blade 221 is attached to the outer blade case 23 with the slit inner blade arranged on the inside. In this way, in the blade unit 20 shown in Fig. 2, the two net outer blades 211 and one slit blade block 22 are attached to the outer blade case 23 to form an outer blade cassette 200. This outer blade cassette 200 is detachably attached to the head cover 122.

[0046] Specifically, the head cover 122 has a substantially cylindrical peripheral wall portion 122c in which an upper opening 122a and a lower opening 122b are formed. The outer blade cassette 200, in which each outer blade faces upward, is inserted from the lower opening 122b side of the head cover 122, so that the outer blade cassette 200 is attached to the head cover 122. At this time, the outer blade cassette 200 is attached to the head cover 122 in a state in which the surface of each outer blade is exposed from the upper opening 122a of the head cover 122. Therefore, in this embodiment, the part of the surface of each outer blade exposed from the upper opening 122a of the head cover 122 is the skin contact surface 20a that comes into contact with the skin (skin surface) of the user.

[0047] In addition, release buttons 23a are formed on both the left and right ends of the outer blade case 23, and by operating these release buttons 23a, the attachment of the head cover 122 and the outer blade cassette 200 can be released.

[0048] As described above, in the blade unit 20 shown in Fig. 2, the head cover 122 with the outer blade cassette 200 attached is attached to the head body 121 with the two net inner blades 212 attached to the driving culms 13 protruding upward from the head body 121. When the head cover 122 with the outer blade cassette 200 attached is attached to the head body 121 with the two net inner blades 212 attached to the driving culms 13, respectively, the two net inner blades 212 are arranged inside the corresponding net outer blades 211.

[0049] By doing so, when the electric shaver 1 is turned on, each inner blade is displaced relative to the corresponding outer blade (relative movement: reciprocating in the Y direction).

[0050] 3 and 4, all of the six blade blocks are attached to the generally frame-shaped outer cutter case 23. In this case, each component may be detachably attached to the outer cutter case 23, or may be attached to the outer cutter case 23 in a state where it cannot be detached.

[0051] In addition, the four net blade blocks 21 and the two slit blade blocks 22 are attached to the outer blade case 23 in a state in which they can float in the Z direction (up and down direction). This allows each blade block to float separately and independently with respect to the head part (main body part) 12 when the head cover 122 with the outer blade cassette 200 attached thereto is attached to the head part main body 121. This allows the outer blade (skin contact surface 20a of the blade unit 20) to be more reliably aligned with the shape of the skin, and allows whiskers (body hair: hair) H to be cut more reliably.

[0052] At least one of the plurality of blade blocks may be held in the head portion (main body portion) 12 in a state in which it cannot float.

[0053] 3 and 4, all of the four net blade blocks 21 are attached to the outer blade case 23 with the net inner blade 212 positioned inside the net outer blade 211, and all of the two slit blade blocks 22 are attached to the outer blade case 23 with the slit inner blade 222 positioned inside the slit outer blade 221. In this way, in the blade unit 20 shown in Figs. 3 and 4, the outer blade cassette 200 is formed by attaching the four net blade blocks 21 and the two slit blade blocks 22 to the outer blade case 23.

[0054] The outer blade cassette 200 is detachably attached to the head cover 122 .

[0055] By doing so, when the electric shaver 1 is turned on, each inner blade is displaced relative to the corresponding outer blade (relative movement: reciprocating in the Y direction).

[0056] Then, the electric shaver 1 is turned on, and with each inner blade displaced relative to the corresponding outer blade, the skin contact surface 20a of the blade unit 20 is placed against the user's skin (skin surface) and moved while sliding in the X direction, so that the whiskers (body hair: hair) H inserted into the blade holes of each outer blade are cut by the outer blade and inner blade.

[0057] Thus, in this embodiment, the head portion 12 corresponds to a main body portion that holds the blade unit 20 with the skin contact surface 20a exposed.

[0058] Next, the configuration of the net outer cutter member 30 used when forming the net outer cutter 211 according to this embodiment will be described with reference to Figs.

[0059] As shown in Fig. 5, the net outer cutter member 30 is in the shape of a substantially rectangular plate, and a fixing portion is formed on the outer peripheral edge of the net outer cutter member 30 for fixing to an outer cutter holding member attached to the outer cutter case 23. The net outer cutter member 30 is bent into an inverted U-shape so that the upper side is convex when viewed along the longitudinal direction, and the fixing portion formed on the net outer cutter member 30 is fixed to a fixing member such as an outer cutter joint to form the net outer cutter 211. The net outer cutter member 30 bent into an inverted U-shape so that the upper side is convex when viewed along the longitudinal direction may be fixed directly to the main housing 111 (the razor main body 10) to form an electric shaver 1 equipped with the net outer cutter 211.

[0060] In this way, the net outer cutter member 30 is a member used to form the net outer cutter 211. In other words, the net outer cutter member 30 is a material for forming the net outer cutter 211. And, by fixing the net outer cutter member 30, which is a material for forming the net outer cutter 211, to a fixing member such as an outer cutter joint or the main body housing 111 in a curved state, a part of the curved portion functions as the net outer cutter 211.

[0061] Specifically, when the central part of the net outer blade member 30 is curved in the X direction (second direction: shaving direction) so as to be convex upward to form the net outer blade 211, it becomes the area with which the net inner blade 212 slides. In other words, the central part of the net outer blade member 30 becomes the area exposed to the outside when the net outer blade 211 is attached to the electric shaver 1, and by bringing this area into contact with the skin, it becomes the area where whiskers (body hair: hair) H can be cut by the net outer blade 211 and the net inner blade 212.

[0062] In this manner, in this embodiment, a cuttable area 31 is formed in the central portion of the net outer blade member 30, which is an area capable of cutting whiskers (body hair) H when the net outer blade 211 is attached to the electric razor 1.

[0063] In the cutting region 31, a large number of generally hexagonal blade holes 33 defined by the crosspieces 32 are formed in a packed state. By making the blade holes 33 formed in the net outer blade member 30 generally hexagonal in this manner, it is possible to suppress a decrease in the efficiency of introducing whiskers (body hair: hair) H facing the blade holes 33 into the blade holes 33.

[0064] In this embodiment, the cuttable region 31 is formed with a plurality of blade holes 33, each of which is substantially hexagonal and defined by the crosspieces 32, arranged in rows in the Y direction (first direction) and the X direction (second direction perpendicular to the first direction). At this time, as shown in FIG. 5, the rows of blade holes 33 extending substantially along the X direction (second direction) are arranged to line up from one end 31a to the other end 31b in the Y direction (first direction) of the cuttable region 31. Similarly, the rows of blade holes 33 extending substantially along the Y direction (first direction) are arranged to line up from one end 31c to the other end 31d in the X direction (second direction) of the cuttable region 31. In this way, the cuttable region 31 is arranged in a state in which a large number of blade holes 33, each of which is substantially hexagonal and defined by the crosspieces 32, are laid out.

[0065] In this embodiment, the direction in which the net inner blade 212 moves relative to the net outer blade 211 when the net outer blade 211 is provided in the electric razor 1 is defined as the Y direction (first direction) of the net outer blade member 30. Also, the direction in which the shaving direction is when the net outer blade 211 is provided in the electric razor 1 is defined as the X direction (second direction) of the net outer blade member 30. Therefore, when the net outer blade 211 is provided in the electric razor 1, the net outer blade 211 has blade holes 33 formed in rows in the X direction (front-back direction: shaving direction) and the Y direction (left-right direction: direction in which the net inner blade moves relative to the net outer blade).

[0066] Furthermore, in this embodiment, each blade hole 33 is defined by a pair of first bars 321, a pair of second bars 322, and a pair of third bars 323 so as to have a substantially hexagonal shape.

[0067] 6, a pair of first bars 321 extending in the Y direction (first direction) are arranged around one blade hole 33 while being spaced apart in the X direction (second direction). One of the second bars 322 inclined with respect to the X direction (second direction) is connected to an end portion on the side of one end 31a in the Y direction (first direction) of the first bar 321 located on the side of one end 31c in the X direction (second direction). The other of the second bars 322 inclined with respect to the X direction (second direction) is connected to an end portion on the side of the other end 31b in the Y direction (first direction) of the first bar 321 located on the side of the other end 31d in the X direction (second direction).

[0068] Furthermore, one side of the third crosspiece 323 inclined in the opposite direction to the second crosspiece 322 with respect to the X direction (second direction) is connected to an end portion on the other end 31b side in the Y direction (first direction) of the first crosspiece 321 located on the one end 31c side in the X direction (second direction) and an end portion of the other second crosspiece 322. Moreover, the other side of the third crosspiece 323 inclined in the opposite direction to the second crosspiece 322 with respect to the X direction (second direction) is connected to an end portion on the one end 31a side in the Y direction (first direction) of the first crosspiece 321 located on the other end 31d side in the X direction (second direction) and an end portion of one of the second crosspieces 322.

[0069] In this way, the blade hole 33 having a hexagonal shape that is point-symmetrical with respect to the center of the blade hole 33 is defined by a pair of first bars 321, a pair of second bars 322 and a pair of third bars 323.

[0070] Thus, in this embodiment, the crosspiece 32 includes a first crosspiece 321 extending approximately parallel to the Y direction (first direction), a second crosspiece 322 connected to the first crosspiece 321, and a third crosspiece 323 connected to the second crosspiece 322, and the first crosspiece 321, the second crosspiece 322 and the third crosspiece 323 define a blade hole 33 having an approximately hexagonal shape.

[0071] Furthermore, if the blade hole 33 is shaped in this way, a corner 33a will be formed at the end of the blade hole 33 in the Y direction (first direction) which is defined by the connecting portion between the second bar 322 and the third bar 323, and which can hold the whiskers (body hair: hair) H introduced into the blade hole 33 in a state where its movement is inhibited.

[0072] If such a corner 33a is provided at the end in the Y direction (first direction) in which the net inner blade 212 moves relatively, it becomes possible to cut the whiskers (body hair: hair) H introduced into the blade hole 33 by moving it so as to drive it into the corner 33a, with the net inner blade 212 moving in the Y direction (first direction). If the whiskers (body hair: hair) H introduced into the blade hole 33 is cut in a state in which it is driven into the corner 33a by the net inner blade 212 moving in the Y direction (first direction), the whiskers (body hair: hair) H is prevented from sliding (sliding sideways) in the X direction (second direction) and from becoming flat, and it becomes possible to more reliably cut the whiskers (body hair: hair) H short. In addition, by suppressing the lateral sliding of the whiskers (body hair: hair) H and more reliably cutting the whiskers (body hair: hair) H short, it is possible to reduce irritation to the skin when using the electric shaver 1.

[0073] Furthermore, in this embodiment, the length of the first crosspiece 321 is longer than the length of the second crosspiece 322 and the length of the third crosspiece 323. This makes the blade hole 33 have a hexagonal shape that is flattened in the X direction (second direction).

[0074] In this embodiment, the length of the second crosspiece 322 is longer than the length of the third crosspiece 323, and the inclination angle of the second crosspiece 322 with respect to the X direction (second direction) is larger than the inclination angle of the third crosspiece 323 with respect to the X direction (second direction). In this way, the corner 33a at one end 31a in the Y direction (first direction) formed in one blade hole 33 and the corner 33a at the other end 31b in the Y direction (first direction) are formed at positions shifted in the X direction (second direction). At this time, the amount of shift in the X direction (second direction) between the two corners 33a is set to be ¼ or less of the length of the blade hole 33 in the X direction (second direction).

[0075] Furthermore, the angle of the connecting portion between second crosspiece 322 and third crosspiece 323, i.e., the angle of corner 33a, is set to be 135 degrees or more and 160 degrees or less. By making corner 33a have an obtuse angle in this manner, it is possible to suppress lateral sliding of whiskers (body hair: hair) H while also reducing irritation to the skin when electric shaver 1 is in use.

[0076] In addition, in this embodiment, no edges are formed around the periphery of the blade hole 33 when viewed along the Z direction. In other words, the corners (including corner 33a) formed at the connecting portions of the bars are rounded or have a shape close to rounded. This makes it possible to further reduce irritation to the skin when the electric shaver 1 is in use.

[0077] Furthermore, in this embodiment, the blade holes 33 formed in the cuttable region 31 are made to have substantially the same shape. This makes it possible to make the introduction efficiency of the whiskers (body hair: hair) H of all the blade holes 33 substantially the same, and prevents variation in the introduction efficiency of the whiskers (body hair: hair) H depending on the position in the cuttable region 31. In other words, the introduction efficiency of the whiskers (body hair: hair) H in the cuttable region 31 becomes more uniform.

[0078] At this time, the thickness of the bars 32 that define the blade holes 33 is also made to be approximately the same. In this embodiment, the thickness of the bars 32 is made to be approximately 0.2 mm. This makes it possible to improve the opening rate of the blade holes 33 formed in the cuttable region 31 while ensuring the strength of the net outer blade member 30. In other words, it is possible to achieve both the efficiency of introducing whiskers (body hair: hair) H and the strength of the net outer blade member 30.

[0079] In addition, in this embodiment, the blade holes 33 are formed in a row in the X direction (second direction) with adjacent blade holes in the X direction (second direction) being shifted in the Y direction (first direction) (so that a row extending in the X direction is formed).

[0080] Specifically, two blade holes 33 adjacent in the X direction (second direction) are formed such that the blade hole 33 located on one end 31c in the X direction (second direction) is shifted toward the other end 31b in the Y direction (first direction) with respect to the blade hole 33 located on the other end 31d in the X direction (second direction). In this manner, in this embodiment, the blade hole 33 on one side (one end 31c side) in the X direction (second direction) is shifted in the same direction (other end 31b side) in the Y direction (first direction) with respect to the blade hole 33 on the other side (other end 31d side) in the X direction (second direction).

[0081] Furthermore, in this embodiment, the blade holes 33 adjacent to each other in the X direction (second direction) are arranged to have substantially the same amount (approximately the same amount) of deviation in the Y direction (first direction).

[0082] Therefore, as one moves from one end 31c to the other end 31d in the X direction (second direction), the blade holes 33 are positioned shifted by approximately the same amount (approximately the same amount) toward one end 31a in the Y direction (first direction), so the row of blade holes 33 formed approximately along the X direction (second direction) is a row that is inclined toward the other end 31d in the X direction (second direction) and toward one end 31a in the Y direction (first direction).

[0083] In addition, in this embodiment, the blade holes 33 are formed in a row in the Y direction (first direction) with adjacent blade holes in the Y direction (first direction) being shifted in the X direction (second direction) (so that a row extending in the Y direction is formed).

[0084] Specifically, two blade holes 33 adjacent in the Y direction (first direction) are formed such that the blade hole 33 located at one end 31a in the Y direction (first direction) is shifted toward one end 31c in the X direction (second direction) with respect to the blade hole 33 located at the other end 31b in the Y direction (first direction). Thus, in this embodiment, the blade hole 33 on one side (one end 31a side) in the Y direction (first direction) is shifted in the same direction (one end 31c side) in the X direction (second direction) with respect to the blade hole 33 on the other side (other end 31b side) in the Y direction (first direction).

[0085] Furthermore, in this embodiment, the blade holes 33 adjacent to each other in the Y direction (first direction) are arranged to be shifted in the X direction (second direction) by approximately the same amount.

[0086] Therefore, as one moves from one end 31a toward the other end 31b in the Y direction (first direction), the blade holes 33 are positioned at positions shifted by approximately the same amount toward the other end 31d in the X direction (second direction), so that the row of blade holes 33 formed approximately along the Y direction (first direction) is a row that is inclined toward the other end 31b in the Y direction (first direction) and toward the other end 31d in the X direction (second direction).

[0087] Thus, in this embodiment, the multiple blade holes 33 are formed in the cuttable region 31 in a regularly-spaced arrangement so as to form rows that intersect with the Y direction (first direction) and the X direction (second direction).

[0088] This makes it possible to suppress variations in the introduction efficiency of whiskers (body hair: hair) H caused by the position of the cutting region 31. In addition, the position of the blade hole 33 can be easily set, making it easier to manufacture the net outer blade member 30.

[0089] Furthermore, if the multiple blade holes 33 are formed in a regularly-spaced arrangement so as to form rows that intersect with the Y direction (first direction) and the X direction (second direction), the corners 33a formed in the blade holes 33 adjacent in the X direction (second direction) will be misaligned in the Y direction (first direction).

[0090] In this way, by shifting the corners 33a formed in the blade holes 33 adjacent in the X direction (second direction) in the Y direction (first direction), it is possible to prevent whiskers (body hair: hair) H introduced into the blade holes 33 adjacent in the X direction (second direction) from being cut simultaneously. As a result, it is possible to reduce the load on the net inner blade 212 and also reduce irritation to the skin when the electric razor 1 is in use.

[0091] If the multiple blade holes 33 are formed in a regularly-spaced arrangement so as to form rows that intersect with the Y direction (first direction) and the X direction (second direction), the first bars 321 that define each blade hole 33 will be shifted in the X direction (second direction).

[0092] In other words, if one of the adjacent blade holes 33 in the Y direction (first direction) (the blade hole 33 on one end 31a side) is designated as the first blade hole 33C and the other (the blade hole 33 on the other end 31b side) is designated as the second blade hole 33D, the first crosspiece 321 defining the first blade hole 33C will be shifted toward the one end 31c in the X direction (second direction) relative to the first crosspiece 321 defining the second blade hole 33D.

[0093] This makes it possible to further reduce variation in ease of introduction of the hair (body hair) H into the blade hole 33 due to its length.

[0094] For example, if the first bars 321 are arranged in a straight line along the Y direction (first direction), and it is difficult to introduce whiskers (body hair: hair) H of a certain length into the blade hole 33, then all of the blade holes 33 arranged in the Y direction (first direction) will be blade holes 33 into which it is difficult to introduce whiskers (body hair: hair) H of that length.

[0095] In contrast to this, if the first bars 321 adjacent to each other in the Y direction (first direction) are shifted in the X direction (second direction), even if it is difficult to introduce hairs (body hair: hair) H of a certain length into one of the blade holes 33, the other blade hole 33 at the shifted position can be made into a blade hole 33 that easily introduces hairs (body hair: hair) H of that length. Also, even if it is difficult to introduce hairs (body hair: hair) H of a different length into the other blade hole 33, it can be made into a blade hole 33 that easily introduces hairs (body hair: hair) H of a different length.

[0096] In this way, by arranging the first bars 321 so as not to be aligned in a straight line along the Y direction (first direction), it is possible to reduce variation in the ease of introduction of the whiskers (body hair: hair) H into the blade holes 33 due to their length. In other words, whiskers (body hair: hair) H of various lengths can be more efficiently introduced into the blade holes 33. As a result, the whiskers (body hair: hair) H can be shaved more efficiently.

[0097] Moreover, the first bars 321 that define each blade hole 33 are also shifted in the Y direction (first direction).

[0098] In other words, the first crosspiece 321 that defines one of the blade holes 33 adjacent in the X direction (second direction) (the blade hole 33 on the one end 31c side) is shifted toward the other end 31b in the Y direction (first direction) relative to the first crosspiece 321 that defines the other blade hole 33 (the blade hole 33 on the other end 31d side).

[0099] This also makes it possible to reduce variation in ease of introduction of the whiskers (body hair: hair) H into the blade holes 33 due to their length.

[0100] For example, when the first bars 321 are lined up at the same position in the X direction (second direction), if it is difficult to introduce a hair (body hair: fur) H of a certain length into the blade hole 33, it will also be difficult to introduce the hair (body hair: fur) H of that length into all of the blade holes 33 lined up in the X direction (second direction). In other words, when moved in the X direction (second direction), blade holes 33 of the same shape will exist at the same position in the Y direction (first direction), and the hair (body hair: fur) H may not be introduced into any of the blade holes 33 and may remain unshaved.

[0101] In contrast to this, if the first bars 321 adjacent to each other in the X direction (second direction) are shifted in the Y direction (first direction), then when they are moved in the X direction (second direction), blade holes 33 of the same shape will not exist at the same position in the Y direction (first direction). That is, introduction holes (blade holes 33) of various shapes will exist in the X direction (second direction), which increases the possibility that the blade holes 33 will be introduced into any of the hole shapes.

[0102] In this way, by arranging the first bars 321 so as not to be lined up at the same position in the X direction (second direction), it is possible to further reduce the variation in ease of introduction of the whiskers (body hair: hair) H into the blade holes 33 due to their length. In other words, whiskers (body hair: hair) H of various lengths can be more efficiently introduced into the blade holes 33. As a result, the whiskers (body hair: hair) H can be shaved more efficiently.

[0103] Furthermore, in this embodiment, at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cuttable region 31, the blade holes 33 are located within a distance corresponding to five rows of blade holes along the X direction (second direction).

[0104] This allows the skin in contact with any position between one end 31a and the other end 31b in the Y direction (first direction) in the cuttable region 31 to face the blade holes 33 over a distance of five rows of blade holes when the electric shaver 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211. In other words, when the electric shaver 1 is moved along the X direction (second direction) by five rows of blade holes with the skin in contact with the outer surface of the net outer blade 211, there will be no portion that comes into contact only with the crosspieces 32 that define the blade holes 33.

[0105] In this way, no matter where hair (body hair) H is present on the skin in contact with the outer surface of the net outer blade 211, the hair (body hair) H can be made to face the blade hole 33 within a distance required to move the electric razor 1 along the X direction (second direction) by five rows of blade holes. In other words, it is possible to prevent hair (body hair) H from being prevented from being introduced into the blade hole 33 by the crosspiece 32.

[0106] Therefore, when an electric shaver 1 equipped with a net outer blade 211 formed using such a net outer blade member 30 is used, all whiskers (body hair: hair) H present on the skin in contact with the outer surface of the net outer blade 211 will have a chance to be introduced into the blade holes 33 during the distance the electric shaver 1 is moved along the X direction (second direction) by the five rows of blade holes. As a result, whiskers (body hair: hair) H can be shaved more efficiently.

[0107] In addition, the area of ​​five rows of blade holes along the X direction (second direction) generally corresponds to the area that roughly corresponds to the area where the skin comes into contact when the skin is placed against a net outer blade, which is made by bending a long, plate-shaped net outer blade member along the short side direction.

[0108] Therefore, in this embodiment, in the five rows of blade holes which are generally in contact with the skin, when viewed along the X direction (second direction), blade holes 33 are present at all positions between one end 31a and the other end 31b in the Y direction (first direction).

[0109] Therefore, by using an electric razor 1 equipped with a net outer blade 211 in which the net outer blade member 30 in this embodiment is curved along the short side direction, it is possible to position all of the skin in contact with the net outer blade 211 facing the blade holes 33 by moving the net outer blade 211 in the X direction (second direction) by one stroke (the length of five rows of blade holes) while the skin is in contact with the net outer blade 211.

[0110] In this manner, by using the net outer blade member 30 according to the present embodiment, it is possible to form the net outer blade 211 that can shave whiskers (body hair) H more efficiently.

[0111] Furthermore, in this embodiment, at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cutting region 31, the blade holes 33 are present in a state in which whiskers (body hair: hair) H can be introduced within a distance of five rows of blade holes along the X direction (second direction).

[0112] Specifically, when the electric shaver 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211, the skin that comes into contact at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cutting region 31 is made to face the blade hole 33 with an opening (opening having an area equal to or larger than the cross-sectional area of ​​the hair) large enough to introduce the hair (body hair: fur) H. At this time, at all positions between one end 31a and the other end 31b in the Y direction (first direction), there are blade holes 33 with a width (length in the X direction) of 0.12 mm or more, which is the average thickness of the hair (body hair: fur) H, for five rows of blade holes.

[0113] In this embodiment, as shown in FIG. 6, when any one of the multiple blade holes 33 formed in the cuttable region 31 is designated as a reference blade hole 33A, the reference blade hole 33A and a blade hole 33B adjacent in the Y direction (first direction) to a blade hole 33 located at a position shifted by five blade hole rows along the X direction (second direction) from the reference blade hole 33A are configured to overlap when viewed along the X direction (second direction).

[0114] In this way, by shifting the positions of the blade holes 33 little by little in the Y direction, blade holes 33 with a width (length in the X direction) of 0.12 mm or more, which is the average thickness of whiskers (body hair: hair) H, are present in all positions between one end 31a and the other end 31b in the Y direction (first direction) for all five rows of blade holes.

[0115] In this way, it is possible to prevent the presence of whiskers (body hair: hair) H that face the blade holes 33 but do not have a chance to be introduced into the blade holes 33 within a distance of five rows of blade holes along the X direction (second direction) on the skin that is in contact with the outer surface of the net outer blade 211. In other words, it is possible to prevent the presence of blade holes 33 that do not contribute to the introduction of whiskers (body hair: hair) H when the electric razor 1 is in use.

[0116] Therefore, it is possible to provide an electric shaver 1 capable of shaving beard (body hair) H more efficiently.

[0117] In the present embodiment, as described above, the crosspiece 32 includes the first crosspiece 321 extending substantially parallel to the Y direction (first direction).

[0118] Therefore, when the electric shaver 1 is moved along the X direction (second direction) with the outer surface of the net outer blade 211 in contact with the skin, the first barb 321 can more reliably raise the flat whiskers (body hair: hair) H.

[0119] 8, in this embodiment, the thickness T1 of the first crosspiece 321 is made smaller than the thicknesses T2, T3 of the second crosspiece 322 and the third crosspiece 323. Specifically, a step portion 32a is formed at the boundary between the second crosspiece 322 and the third crosspiece 323 and the first crosspiece 321.

[0120] In this way, by reducing the thickness of the first crosspiece 321 having the function of raising the flattened hairs (body hair: hair) H, when the electric shaver 1 is moved in the X direction (second direction) with the outer surface of the net outer blade 211 in contact with the skin, the first crosspiece 321 can be more easily moved under the flattened hairs (body hair: hair) H. As a result, the flattened hairs (body hair: hair) H can be more reliably raised by the first crosspiece 321, making it possible to shave the hairs (body hair: hair) H more efficiently.

[0121] [Actions and Effects] The following describes the net outer cutter member shown in the above embodiment, the net outer cutter formed using the net outer cutter member, and the characteristic configuration of an electric razor equipped with the net outer cutter, as well as the effects obtained thereby.

[0122] (Technology 1) The net outer blade member 30 shown in the above embodiment is a member capable of forming the net outer blade 211 to be provided in the electric shaver 1. This net outer blade member 30 has a cutting region 31 capable of cutting whiskers (body hair: hair) H in a state in which the net outer blade 211 is provided in the electric shaver 1.

[0123] In addition, in the cuttable region 31, a plurality of blade holes 33, each having an approximately hexagonal shape defined by crosspieces 32, are formed in rows in the Y direction (first direction) and the X direction (second direction perpendicular to the first direction).

[0124] Here, the Y direction (first direction) is the direction in which the net inner blade 212 moves relative to the net outer blade 211 when the net outer blade 211 is provided in the electric razor 1. Moreover, the X direction (second direction) is the direction in which the net outer blade 211 is shaved when the net outer blade 211 is provided in the electric razor 1.

[0125] Furthermore, the blade holes 33 are formed in a row in the X direction (second direction) with adjacent blade holes in the X direction (second direction) being shifted in the Y direction (first direction).

[0126] Furthermore, at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cuttable region 31, the blade holes 33 are present within a distance equivalent to five rows of blade holes along the X direction (second direction).

[0127] By forming a net outer blade 211 using a net outer blade member 30 having such blade holes 33 and attaching this net outer blade 211 to an electric razor 1, it is possible to obtain an electric razor 1 that can shave beard (body hair) H more efficiently.

[0128] For example, when an electric shaver 1 equipped with a net outer blade 211 formed using the net outer blade member 30 shown in the above embodiment is used, when the electric shaver 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211, any skin that comes into contact with any position between one end 31a and the other end 31b in the Y direction (first direction) in the cuttable region 31 will face the blade holes 33 over a distance of five rows of blade holes. In other words, when the electric shaver 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211 by five rows of blade holes, there will be no portion that comes into contact only with the crosspieces 32 that define the blade holes 33.

[0129] Therefore, no matter where hair (body hair) H is present on the skin in contact with the outer surface of the net outer blade 211, the hair (body hair) H can be made to face the blade hole 33 within a distance required to move the electric razor 1 along the X direction (second direction) by five rows of blade holes. In other words, it is possible to prevent hair (body hair) H from being prevented from being introduced into the blade hole 33 by the crosspiece 32.

[0130] In this way, when an electric razor 1 equipped with a net outer blade 211 formed using the net outer blade member 30 shown in the above embodiment is used, all whiskers (body hair: hair) H present on the skin in contact with the outer surface of the net outer blade 211 are given an opportunity to be introduced into the blade holes 33 during the distance it takes for the electric razor 1 to move along the X direction (second direction) by five rows of blade holes.

[0131] Furthermore, since the blade hole 33 formed in the net outer blade member 30 shown in the above embodiment has an approximately hexagonal shape, it is possible to suppress a decrease in the efficiency of introducing the whiskers (body hair: hair) H facing the blade hole 33 into the blade hole 33.

[0132] Therefore, if the electric shaver 1 is provided with the net outer blade 211 formed using the net outer blade member 30 shown in the above embodiment, it will be possible to shave whiskers (body hair) H more efficiently.

[0133] In this manner, by using the net outer blade member 30 shown in the above embodiment, it is possible to form the net outer blade 211 capable of shaving whiskers (body hair) H more efficiently.

[0134] (Technology 2) In the above (Technology 1), at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cutting region 31, the blade holes 33 may be present in a state in which they can introduce whiskers (body hair) H within a distance corresponding to a movement of five rows of blade holes along the X direction (second direction).

[0135] For example, when the electric razor 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211, it is possible to make the skin in contact at any position between one end 31a and the other end 31b in the Y direction (first direction) in the cutting area 31 face the blade hole 33 in which there is an opening (an opening having an area greater than or equal to the cross-sectional area of ​​a hair) large enough to introduce a hair (body hair) H.

[0136] In this way, it is possible to prevent the presence of hairs (body hair: fur) H that face the blade holes 33 but do not have a chance to be introduced into the blade holes 33 within a distance of five rows of blade holes along the X direction (second direction) on the skin that is in contact with the outer surface of the net outer blade 211. In other words, it is possible to more reliably prevent the presence of blade holes 33 that do not contribute to the introduction of hairs (body hair: fur) H when the electric razor 1 is in use.

[0137] As a result, it is possible to provide an electric shaver 1 capable of shaving beard (body hair) H more efficiently.

[0138] (Technology 3) In the above (Technology 1) or (Technology 2), the blade holes 33 formed in the cuttable region 31 may have substantially the same shape.

[0139] This makes it possible to make the introduction efficiency of the hairs (body hair: hair) H approximately the same for all of the blade holes 33. Therefore, it is possible to suppress variation in the introduction efficiency of the hairs (body hair: hair) H depending on the position of the cuttable region 31. In other words, it is possible to make the introduction efficiency of the hairs (body hair: hair) H in the cuttable region 31 more uniform.

[0140] (Technology 4) In addition, in any of the above-mentioned (Technology 1) to (Technology 3), the blade holes 33 on one side in the X direction (second direction) may be shifted in the same direction in the Y direction (first direction) with respect to the blade holes 33 on the other side in the X direction (second direction).

[0141] This allows the blade holes 33 to be regularly arranged, making it possible to suppress variations in the efficiency of introducing whiskers (body hair: hair) H that occur depending on the position of the cutting region 31. Furthermore, regularly arranging the blade holes 33 makes it easier to set the positions of the blade holes 33, making it easier to manufacture.

[0142] (Technology 5) In any of the above (Technology 1) to (Technology 4), the blade holes 33 adjacent to each other in the X direction (second direction) may be shifted in the Y direction (first direction) by approximately the same amount.

[0143] This allows the multiple blade holes 33 to be arranged more regularly, making it possible to suppress variations in the introduction efficiency of whiskers (body hair: hair) H that occur depending on the position of the cutting region 31. Furthermore, arranging the multiple blade holes 33 regularly makes it easier to set the positions of the blade holes 33, making it easier to manufacture.

[0144] (Technology 6) In addition, in any of the above (Technology 1) to (Technology 5), when any one of the multiple blade holes 33 formed in the cuttable region 31 is designated as a reference blade hole 33A, the reference blade hole 33A and a blade hole 33B adjacent in the Y direction (first direction) to a blade hole 33 located at a position shifted by five blade hole rows in the X direction (second direction) from the reference blade hole 33A may overlap when viewed in the X direction (second direction).

[0145] This allows the blade holes 33 to be regularly arranged, making it possible to suppress variations in the efficiency of introducing whiskers (body hair: hair) H that occur depending on the position of the cutting region 31. Furthermore, regularly arranging the blade holes 33 makes it easier to set the positions of the blade holes 33, making it easier to manufacture.

[0146] (Technology 7) In any of the above (Technology 1) to (Technology 6), the crosspiece 32 may include a first crosspiece 321 extending approximately parallel to the Y direction (first direction).

[0147] In this way, when the electric shaver 1 is moved along the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211, the first rail 321 can more reliably raise the flat whiskers (body hair: hair) H, making it possible to shave the whiskers (body hair: hair) H more efficiently.

[0148] (Technology 8) In addition, in the above (Technology 7), when one of adjacent blade holes 33 in the Y direction (first direction) is designated as the first blade hole 33C and the other is designated as the second blade hole 33D, the first crosspiece 321 defining the first blade hole 33C and the first crosspiece 321 defining the second blade hole 33D may be misaligned in the X direction (second direction).

[0149] This makes it possible to further reduce variation in ease of introduction of the hair (body hair) H into the blade hole 33 due to its length.

[0150] For example, if the first bars 321 are arranged in a straight line along the Y direction (first direction), and it is difficult to introduce whiskers (body hair: hair) H of a certain length into the blade hole 33, then all of the blade holes 33 arranged in the Y direction (first direction) will be blade holes 33 into which it is difficult to introduce whiskers (body hair: hair) H of that length.

[0151] In contrast to this, if the first bars 321 adjacent to each other in the Y direction (first direction) are shifted in the X direction (second direction), even if it is difficult to introduce hairs (body hair: hair) H of a certain length into one of the blade holes 33, the other blade hole 33 at the shifted position can be made into a blade hole 33 that easily introduces hairs (body hair: hair) H of that length. Also, even if it is difficult to introduce hairs (body hair: hair) H of a different length into the other blade hole 33, it can be made into a blade hole 33 that easily introduces hairs (body hair: hair) H of a different length.

[0152] In this way, by arranging the first bars 321 so as not to be aligned in a straight line along the Y direction (first direction), it is possible to reduce variation in the ease of introduction of the whiskers (body hair: hair) H into the blade holes 33 due to their length. In other words, whiskers (body hair: hair) H of various lengths can be more efficiently introduced into the blade holes 33. As a result, the whiskers (body hair: hair) H can be shaved more efficiently.

[0153] (Technology 9) In the above (Technology 7) or (Technology 8), the crosspiece 32 may include a second crosspiece 322 connected to the first crosspiece 321, and a third crosspiece 323 connected to the second crosspiece 322. The blade hole 33 may be formed with a corner 33a at an end in the Y direction (first direction) that can hold the whiskers (body hair: hair) H introduced into the blade hole 33 in a state in which movement is suppressed. The corner 33a may be formed at a connecting portion between the second crosspiece 322 and the third crosspiece 323.

[0154] In this way, the whiskers (body hair: hair) H introduced into the blade hole 33 can be cut by the net inner blade 212 moving in the Y direction (first direction) in a state where the whiskers (body hair: hair) H introduced into the blade hole 33 is moved so as to be driven into the corner 33a. In this way, by cutting the whiskers (body hair: hair) H introduced into the blade hole 33 in a state where the whiskers (body hair: hair) H is driven into the corner 33a by the net inner blade 212 moving in the Y direction (first direction), the whiskers (body hair: hair) H is prevented from sliding (sliding sideways) in the X direction (second direction) and from becoming flat, and the whiskers (body hair: hair) H can be cut short more reliably.

[0155] Furthermore, by suppressing the lateral sliding of the whiskers (body hair: hair) H and more reliably cutting the whiskers (body hair: hair) H short, it is possible to reduce irritation to the skin when using the electric shaver 1.

[0156] (Technology 10) In the above (Technology 9), the corners 33a formed in the blade holes 33 adjacent to each other in the X direction (second direction) may be shifted in the Y direction (first direction).

[0157] This prevents the whiskers (body hair: hair) H introduced into adjacent blade holes 33 in the X direction (second direction) from being cut simultaneously, thereby reducing the load on the net inner blade 212 and also reducing the irritation to the skin when using the electric razor 1.

[0158] (Technology 11) In the above (Technology 9) or (Technology 10), the thickness T1 of the first crosspiece 321 may be smaller than the thicknesses T2, T3 of the second crosspiece 322 and the third crosspiece 323.

[0159] In this way, when the electric shaver 1 is moved in the X direction (second direction) with the skin in contact with the outer surface of the net outer blade 211, the first rail 321 can be more easily slipped under the flattened whiskers (body hair: hair) H. As a result, the flattened whiskers (body hair: hair) H can be more reliably raised by the first rail 321, so that the whiskers (body hair: hair) H can be shaved more efficiently.

[0160] (Technology 12) The net outer cutter 211 shown in the above embodiment is formed using the net outer cutter member 30 disclosed in any one of the above (Technology 1) to (Technology 11).

[0161] If the net outer blade 211 is formed using such a net outer blade member 30, it is possible to provide the net outer blade 211 capable of shaving whiskers (body hair) H more efficiently.

[0162] (Technical feature 13) The electric shaver 1 shown in the above embodiment is equipped with the outer net blade 211 disclosed in (Technical feature 12) above.

[0163] In this way, it is possible to obtain an electric shaver 1 that is capable of shaving hair more efficiently.

[0164] [others] The above describes the contents of the net outer blade member, the net outer blade formed using the net outer blade member, and the electric razor equipped with the net outer blade according to the present disclosure, but it will be obvious to those skilled in the art that the present disclosure is not limited to these descriptions and that various modifications and improvements are possible.

[0165] For example, the present disclosure can be applied to the embodiments in which the configurations shown in the above embodiments are modified, replaced, added, omitted, etc. Also, it is possible to combine the components described in the above embodiments to form new embodiments.

[0166] In addition, in the above embodiment, the electric razor 1 including the grip portion 11 and the head portion 12 has been exemplified, but the present disclosure can also be applied to an electric razor that does not include a head portion. In this case, the side of the razor body where the blade unit is supported corresponds to the main body portion.

[0167] It is also possible for the blade unit 20 to have two blade blocks, or it is also possible for the blade unit 20 to have four or more blade blocks. Even in this case, the arrangement order of the blade blocks can be set appropriately.

[0168] In addition, in the above embodiment, an example was given of a net outer blade member 30 in which blade holes 33 are regularly arranged in the cuttable region 31, but it is also possible to form blade holes 33 that are randomly arranged in the cuttable region 31, or to have blade holes 33 of different sizes.

[0169] In addition, in the above embodiment, a reciprocating electric shaver 1 is exemplified, but the present disclosure can also be applied to a rotary electric shaver. In this case, the circumferential direction is the first direction, and the radial direction is the second direction. Also, any point in the circumferential direction is one end in the first direction and the other end in the first direction, the outer circumferential end is one end in the second direction, and the center is the other end in the second direction.

[0170] Additionally, the blade block, razor body, and other detailed specifications (shape, size, layout, etc.) can be modified as appropriate. [Industrial Applicability]

[0171] As described above, the net outer blade member, net outer blade formed using the net outer blade member and electric razors equipped with a net outer blade according to the present disclosure are capable of shaving hair more efficiently and can be used not only for beards but also for treating various body hairs.
