[0001] The utility model relates to the field of shavers, in particular to an electric shaver mesh cover, a cutting assembly and a shaver. Background Art

[0002] The electric shaver is mainly composed of a mesh cover, a moving blade, a micro motor and a housing. The micro motor drives the moving blade to rotate, and then the blade on the moving blade cooperates with the blade in the mesh cover to achieve shaving, which is convenient and quick.

[0003] A Chinese utility model patent with application number 201922235709.0 discloses a rotary electric shaver blade net assembly, including a shell, a blade net is arranged on the upper end of the shell, the blade net includes an outer ring blade net and an inner ring blade net, the center of the outer ring blade net coincides with the center of the inner ring blade net, a plurality of first beard inlet grooves are arranged on the outer ring blade net, a plurality of second beard inlet grooves are arranged on the inner side of the outer ring blade net, a plurality of first blades are arranged on the inner side of the inner ring blade net; the first beard inlet grooves and the second beard inlet grooves are both arranged radially from the center of the outer ring blade net or the inner ring blade net.

[0004] In the above structure, the widths of the first and second hair inlet grooves remain unchanged. When the hair inlet grooves of this structure are in use, excessively long hair is easily pushed against the skin, making it difficult to introduce it into the mesh cover, which can easily cause hair jamming and pulling, resulting in pain. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide an electric shaver mesh cover which is easy to introduce overlong hair into the mesh cover in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cutting assembly with the above-mentioned electric shaver mesh cover in view of the current status of the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a shaver with the above-mentioned cutting assembly in view of the current status of the prior art.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: an electric shaver mesh cover for covering a rotatable moving blade and cooperating with the moving blade for cutting, the mesh cover comprising a support frame and an annular inner blade net and an annular outer blade net both arranged on the support frame, the annular inner blade net and the annular outer blade net being arranged cocentrically, the annular outer blade net comprising a first connecting portion extending upward from the outer edge of the annular inner blade net, a blade net portion extending outward from the upper end of the first connecting portion, and a second connecting portion extending downward from the outer end of the blade net portion and connected to the support frame, a plurality of main beard feed grooves are spaced apart in the circumferential direction of the blade net portion, the first connecting portion is provided with a first beard feed groove which is connected to the main beard feed groove and has a width greater than the main beard feed groove, and / or the second connecting portion is provided with a second beard feed groove which is connected to the main beard feed groove and has a width greater than the main beard feed groove.

[0009] In order to improve the structural strength of the blade mesh and evenly distribute the secondary beard entry slots, each of the main beard entry slots is connected to one of the first beard entry slot and the second beard entry slot, and the adjacent main beard entry slots are alternately connected to the first beard entry slot and the second beard entry slot. Although the main beard entry slot is connected to the first beard entry slot and the second beard entry slot at the same time, it can make longer beards enter the mesh cover efficiently, but too many secondary beard entry slots will weaken the connection strength between the blade mesh and the support frame, reducing the service life of the mesh cover; the adjacent main beard entry slots are alternately connected to the first beard entry slot and the second beard entry slot so that the secondary beard entry slots are evenly distributed, which not only ensures the structural strength but also facilitates the beard entry.

[0010] In order to reduce whisker jamming, the groove wall of the main whisker inlet groove is smoothly connected to the groove wall of the first whisker inlet groove, and the groove wall of the main whisker inlet groove is smoothly connected to the groove wall of the second whisker inlet groove.

[0011] In order to increase the amount of hair entering, the first hair entering slot includes a first fixed width section and a first variable width section which are connected, the first fixed width section is located at the first connecting portion, and the first variable width section is located at the knife net portion. The first variable width section of the first hair entering slot is located at the knife net portion. Since the first variable width section is larger than the width of the main hair entering slot, the amount of hair entering can be increased. Furthermore, since an annular inner knife net is also provided inside the annular outer knife net, the annular inner knife net has a certain shielding effect, and the first variable width section is not easy to get stuck in the skin when it directly contacts the skin.

[0012] The second hair entry groove comprises a second fixed width section and a second variable width section which are both located at the second connecting portion. The second variable width section is located at the second connecting portion to prevent the second variable width section from getting stuck in the skin and thus cutting the skin.

[0013] Preferably, the main whisker feeding groove is a strip-shaped groove, and the length direction of the main whisker feeding groove is substantially the same as the radial direction of the annular outer knife net.

[0014] In order to prevent the skin from getting stuck and to improve the cutting efficiency, the main hair feeding groove is arc-shaped in the length direction.

[0015] Preferably, a recessed portion connecting the inner annular blade net and the outer annular blade net is provided between the two, the first connecting portion is extended upward from the outer edge of the recessed portion, and the first beard feeding groove on the first connecting portion extends to the recessed portion.

[0016] The utility model solves the second technical problem by adopting the following technical solution: an electric shaver cutting assembly comprises a rotatable moving blade, and the moving blade is covered with the electric shaver mesh cover.

[0017] The technical solution adopted by the utility model to solve the third technical problem is: a shaver, which is applied with the above-mentioned electric shaver cutting assembly.

[0018] Compared with the prior art, the advantages of the utility model are: the annular outer blade net comprises a blade net portion and a first connecting portion and a second connecting portion which are located at the inner and outer edges of the blade net portion and are roughly perpendicular to the blade net portion; the first connecting portion and the second connecting portion are respectively provided with a first beard inlet groove and a second beard inlet groove which are connected to the main beard inlet groove of the annular outer blade net and have a larger width; when shaving, the hair can be introduced into the main beard inlet groove from the first beard inlet groove and the second beard inlet groove; since the first beard inlet groove and the second beard inlet groove extend vertically, it is convenient to introduce excessively long hair into the blade net, and hair jamming is less likely to occur.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 6 The figure shows a preferred embodiment of the electric shaver mesh cover of the utility model, which is used to cover a rotatable moving blade (not shown in the figure) and cooperate with the moving blade for cutting.

[0027] The net cover includes a support frame 1 and an annular inner knife net 2 and an annular outer knife net 3 both arranged on the support frame 1, and the inner sides of the annular inner knife net 2 and the annular outer knife net 3 are provided with a first blade 20 and a second blade 30 corresponding to the position of the movable blade; the annular inner knife net 2 and the annular outer knife net 3 are arranged cocentrically, and a circle of recessed portion 4 connecting the annular inner knife net 2 and the annular outer knife net 3 is arranged between the two.

[0028] like Figure 3 As shown, the annular outer knife net 3 includes a first connection portion 31 extending upward from the outer edge of the lower recess 4, a knife net portion 32 extending outward from the upper end of the first connection portion 31, and a second connection portion 33 extending downward from the outer end of the knife net portion 32 and connected to the support frame 1. The intersections of the first connection portion 31 and the knife net portion 32, and the intersections of the knife net portion 32 and the second connection portion 33 are all in a certain arc, which is safer. The knife net portion 32 is provided with a plurality of main feed grooves 321 spaced apart in the circumferential direction. The main feed grooves 321 are strip grooves. The length direction of the main feed grooves 321 is roughly the same as the radial direction of the annular outer knife net 3. The main feed grooves 321 are arc-shaped in the length direction. Such a design can improve the cutting efficiency and prevent the skin from getting stuck. Figure 6 The arc of the main inlet groove 321 is greater than Figure 1 The arc of the main inlet groove 321 in.

[0029] The first connecting portion 31 is provided with a first beard entry slot 311 which is connected to the main beard entry slot 321 and has a width greater than the main beard entry slot 321, and the second connecting portion 33 is provided with a second beard entry slot 331 which is connected to the main beard entry slot 321 and has a width greater than the main beard entry slot 321; each main beard entry slot 321 is connected to one of the first beard entry slot 311 and the second beard entry slot 331, and adjacent main beard entry slots 321 are alternately connected to the first beard entry slot 311 and the second beard entry slot 331. Although the main beard entry slot 321 is connected to the first beard entry slot 311 and the second beard entry slot 331 at the same time, it can make longer beards enter the net cover efficiently, but too many secondary beard entry slots will weaken the connection strength between the blade net part and the support frame, reducing the service life of the net cover; adjacent main beard entry slots 321 are alternately connected to the first beard entry slot 311 and the second beard entry slot 331, so that the secondary beard entry slots are evenly distributed, which is conducive to the entry of beards.

[0030] In other embodiments, the second connecting portion 33 may be a part of the supporting frame 1 , and the second whisker feeding groove 331 is directly formed on the supporting frame 1 .

[0031] like Figures 3 to 5As shown, the groove wall of the main beard inlet groove 321 is smoothly connected to the groove wall of the first beard inlet groove 311, and the groove wall of the main beard inlet groove 321 is also smoothly connected to the groove wall of the second beard inlet groove 331. Specifically, the first beard inlet groove 311 includes a first fixed width section 3111 and a first variable width section 3112 that are connected. The first fixed width section 3111 is located at the first connecting portion 31 and partially extends to the lower recessed portion 4; the first variable width section 3112 is located at the knife net portion 32. The first variable width section 3112 of the first beard inlet groove 311 is located at the knife net portion 32. Since the first variable width section 3112 is larger than the width of the main beard inlet groove 321, the amount of beard inlet can be increased. Moreover, since an annular inner knife net 2 is also provided inside the annular outer knife net 3, the annular inner knife net 2 has a certain shielding effect, and the first variable width section 3112 is not easy to get stuck in the skin.

[0032] The second hair entry slot 331 also includes a second constant width section 3311 and a second variable width section 3312, both of which are located at the second connecting portion 33. The second variable width section 3312 should not be arranged on the blade mesh portion 32, because the opening at the outer edge of the blade mesh portion 32 is too large and may get stuck in the skin.

[0033] The annular inner knife net 2 in this embodiment includes a third connection portion extending upward from the inner edge of the lower recess, a connection member 21 extending radially inwardly from the third connection portion in a circumferential interval, and an inner ring blade 22 extending radially inwardly from the third connection portion in the interval between adjacent connection members 21, wherein the connection member 21 is connected to the center plate 5, and a beard entry gap is left between the inner ring blade 22 and the center plate 5. The annular inner knife net 2 can also be designed as the structure of the annular outer knife net 3.

[0034] The electric shaver mesh cover of the invention is produced by a stamping process.

[0035] The utility model also provides an electric shaver cutting assembly, comprising a rotatable moving blade, the moving blade is covered with the electric shaver mesh cover.

[0036] The utility model also provides a shaver, which is applied with the electric shaver cutting assembly.
