In the present embodiment, in the process of reciprocating the movable blade 13 relative to the fixed blade 12, the tooth edge portions 14 of the fixed blade 12 and the tooth edge portions 14 of the movable blade 13 form a staggered cutting motion, so as to cut the hair wound on the rolling brush.

In addition, in the process of moving the N movable blades 13, the moving directions of at least two movable blades 13 are opposite, so that the inertia force can be mutually counteracted between the movable blades 13 with opposite movement, and the vibration of the system is reduced.

In the following, the cutting apparatus 100 will be described in detail with reference to the drawings by taking N as an example, where N may also be 2, 3, 4, 6, etc., but the present invention is not limited thereto, and those skilled in the art may flexibly select the value of N as needed.

In this embodiment, the housing 11 includes a first housing 111 and a second housing 112 abutting against the first housing 111, the first housing 111 and the second housing 112 together enclose a containing chamber with an opening 110, and the fixed blade 12, the movable blade 13 and all or part of the driving mechanism are located in the containing chamber.

Further, the driving mechanism includes a rotating shaft 15 and a plurality of driving members 16 disposed on the rotating shaft 15 at intervals, wherein the number of the driving members 16 is N +1, N-1 or N. It will be appreciated that the number of drivers 16 may vary from embodiment to embodiment. Next, the present invention will be described in detail for each embodiment based on the number of the driving members 16.

In an embodiment of the present invention, with continued reference to fig. 1 to 6, the number of the driving members 16 is N +1, that is, the number of the driving members 16 is 6, the number of the movable blades 13 is 5, 5 movable blades 13 are located at one side of the rotating shaft 15, one movable blade 13 is disposed between two adjacent driving members 16, the driving members 16 have two end surfaces 160 disposed oppositely, each movable blade 13 has two driven portions 130 disposed oppositely along the length direction of the blade, and the end surfaces 160 are in linkage fit with the driven portions 130. Specifically, in the first position, one driven portion 130 of the movable blade 13 is pushed against the end surface 160 of the adjacent driving member 16 to the second position; in the second position, the other driven portion 130 of the movable blade 13 is pushed against the end surface 160 of the adjacent driving member 16 to the first position. That is, the driving member 16 drives the movable blade 13 by the contact of the end surface 160 with the force-receiving portion 130 of the movable blade 13, and the movable blade 13 can be driven by the adjacent driving member 16 to perform a cutting motion no matter whether the movable blade 13 is in the first position or the second position.

With continued reference to fig. 3 and 6, for convenience of description, the first position may be defined as a left side, the second position may be defined as a right side, and in a left-to-right direction, the 5 movable blades 13 may be respectively defined as a first movable blade, a second movable blade, and a third movable blade … …, and correspondingly, the 6 driving members 16 may be respectively defined as a first driving member, a second driving member, and a third driving member … …, which is specifically referred to in the drawings.

In one embodiment of the present invention, with continued reference to fig. 3-5, each driving member 16 is a symmetrical driving member in the axial direction perpendicular to the rotating shaft 15, and the moving directions of two adjacent movable blades 13 are opposite. It should be noted that the term "symmetrical driving member" in this embodiment means that the driving member 16 is symmetrical along a symmetry plane a-a perpendicular to the axial direction of the rotating shaft 15. It can be understood that, when the moving directions of the two adjacent moving blades 13 are opposite, the inertia force between the first moving blade and the second moving blade can be mutually offset, the inertia force between the third moving blade and the fourth moving blade can be mutually offset, and at this time, the vibration of the moving blade 13 to the system can be minimized.

As shown in fig. 3-5, the driving members 16 may be cam-like, and the end surface 160 has a maximum axial length position point and a minimum axial length position point along the axial direction of the rotating shaft 15, the maximum axial length position point and the minimum axial length position point being respectively located at two opposite sides of the rotating shaft 15, and the maximum axial length position point of one driving member 16 is opposite to the minimum axial length position point of the other driving member 16 in two adjacent driving members 16. That is, the driving member 16 has a larger axial length end and a smaller axial length end, and it should be noted that the larger axial length end and the smaller axial length end are relative terms in this embodiment.

It should be noted that, with continued reference to fig. 4-5, the driving member 16 of the present embodiment is symmetrical along B-B of fig. 5 in addition to a-a of fig. 4, the two end surfaces 160 are divided into front and rear two partial surfaces by B-B, respectively, and the length of a connecting line between any two opposite points on the front partial surface or the rear partial surface of the two end surfaces 160 gradually decreases from top to bottom.

Since the driving principle of the adjacent driving member 16 to the movable blade 13 is the same, the present embodiment will only describe the driving principle of the first movable blade in detail. The end of the first driving member with larger axial length is opposite to the end of the second driving member with smaller axial length, and conversely, the end of the first driving member with smaller axial length is opposite to the end of the second driving member with larger axial length. Thus, in this embodiment, the second driving member abuts against the driven portion of the first moving blade through the end with the larger axial length, and further drives the first moving blade to move towards the left side (i.e. towards the direction close to the end with the smaller axial length of the first driving member).

In another embodiment of the present invention, when 5 movable blades 13 move simultaneously, only a part of the adjacent movable blades 13 move in opposite directions, and the other part of the adjacent movable blades 13 move in the same direction. In order to realize the above-mentioned same-direction or opposite-direction movement of the movable blades 13, as shown in fig. 6-8, among the 6 driving members 16, a part of the driving members 16 may be symmetrical driving members, and the other part is a flat asymmetrical driving member 16, the moving directions of the movable blades 13 on both sides of the symmetrical driving member 16 are opposite, and the moving directions of the movable blades 13 on both sides of the asymmetrical driving member 16 are the same. Specifically, the first moving blade and the second moving blade both move towards the left, the third moving blade moves towards the right, the fourth moving blade moves towards the left, and the fifth moving blade moves towards the left, and accordingly, the first driving piece, the third driving piece, the fourth driving piece, and the sixth driving piece are symmetrical driving pieces, and the second driving piece and the fifth driving piece are asymmetrical driving pieces.

It should be noted that, with continued reference to fig. 7, the asymmetric driving member of the present embodiment is only asymmetric along the symmetry plane C-C perpendicular to the axial direction of the rotating shaft 15. However, the asymmetric driving member may also be symmetrical along D-D of fig. 8, the two end surfaces 160 are divided into upper and lower two partial surfaces by D-D, and the lengths of connecting lines between any two opposite points on the upper or lower partial surfaces of the two end surfaces 160 may be equal. In addition, the structure of the symmetrical driving member in this embodiment is the same as that of the driving member in fig. 3-5, the asymmetrical driving member 16 is disposed obliquely toward the rotation shaft 15, both end surfaces 160 of the symmetrical driving member and the asymmetrical driving member have concave portions and convex portions, and the convex portions of the end surfaces 160 of the symmetrical driving member correspond to the concave portions of the end surfaces 160 of the adjacent asymmetrical driving member. With continued reference to fig. 6-8, the second driver is tilted to the left, the fifth driver is tilted to the left, the concave portion of the end surface 160 of the first driver corresponds to the convex portion of the end surface 160 of the second driver, the concave portion of the other end surface 160 of the second driver corresponds to the convex portion of the end surface 160 of the third driver, the convex portion of the other end surface 160 of the third driver corresponds to the concave portion of the end surface 160 of the fourth driver, the concave portion of the other end surface 160 of the fourth driver corresponds to the convex portion of the end surface 160 of the fifth driver, and the concave portion of the other end surface 160 of the fifth driver corresponds to the convex portion of the end surface 160 of the sixth driver.

Of course, the number and arrangement of the symmetrical driving elements and the asymmetrical driving elements are not limited thereto, and it is within the scope of the present application as long as the opposite movement directions of at least two movable blades can be achieved. Further, with reference to fig. 2, the driving mechanism of this embodiment further includes a driving motor 17, a belt 18 and two belt pulleys 19, the belt 18 is sleeved on the belt pulleys 19, one of the belt pulleys 19 is fixedly sleeved on the rotating shaft 15, the other belt pulley 19 is connected with the rotating shaft of the driving motor 17, the belt 18 penetrates through the second housing 112 and is sleeved on the belt pulley 19 on the rotating shaft 15, the driving motor 17 is located outside the housing 11, and in addition, bearings 20 are disposed at two opposite ends of the rotating shaft 15, so that friction force can be reduced when the rotating shaft 15 rotates.

When the driven portion 130 of the movable blade 13 abuts against the end surface 160 of the driver 16, the two may be in line contact or point contact. The line contact means that the contact between the passive portion 130 and the end surface 160 is always a line, and the point contact means that the contact between the passive portion 130 and the end surface 160 is always a point or a plurality of points.

In the above embodiment, with continued reference to fig. 4-5 and 7-8, when the driven portion 130 of the movable blade 13 and the end surface 160 of the driving member 16 form a line contact, the end surface 160 of the symmetrical driving member may be a smooth curved surface, and the smooth curved surface is divided into a concave portion and a convex portion, wherein the most concave position point of the concave portion coincides with the axial length minimum position point, and the most convex position point of the convex portion coincides with the axial length maximum position point. The concave portion of one end surface 160 of the asymmetric driver corresponds to the convex portion of the other end surface 160, and the convex portion of one end surface 160 of the asymmetric driver corresponds to the concave portion of the other end surface 160. Specifically, the driving member 16 drives the movable blade 13 to reciprocate by means of the smooth curved surface of the end surface 160. It should be noted that, at this time, the motion track of each movable blade 13 is in an arc shape under the driving of the driving member 16, and because the movable blades 13 have motion components along the arrangement direction of the movable blades 13, the movable blades 13 can still form the staggered cutting motion with the fixed blades 12 at this time.

In an embodiment of the present invention, when the driven portion 130 of the movable blade 13 forms a point contact with the end surface 160 of the driving member 16, the end surface 160 of the asymmetric driving member is an inclined plane, the end surface 160 of the symmetric driving member can be an inclined plane, and the point where the axial length of the end surface 160 is the largest and the point where the axial length of the end surface 160 is the smallest are respectively located at the top and the bottom of the end surface 160, and the cross section of the driving member 16 is an isosceles trapezoid, and the axial length of the driving member 16 gradually decreases from the top to the bottom of the driving member 16. It should be noted that, at this time, the motion track of each movable blade 13 is linear under the driving of the driving member 16.

Further, in this embodiment, with continued reference to fig. 2-3, the cutting device 100 further comprises: and the N elastic pressing pieces 21 are respectively fixed on the first shell 111 and the movable blade 13 at one end, and the other end of each elastic pressing piece 21 is fixed on one side of the movable blade 13 far away from the fixed blade 12 so as to press and match the fixed blade 12 and the movable blade 13. Specifically, the elastic pressing member 21 may be a spring member, and under the action of the elastic pressing member 21, the tooth edge portion 14 of the fixed blade 12 is tightly attached to the tooth edge portion 14 of the movable blade 13, so as to realize the staggered cutting motion of the movable blade 13 and the fixed blade 12. In addition, because the tooth edge part 14 of the fixed blade 12 is tightly attached to the tooth edge part 14 of the movable blade 13, the hair can be prevented from being thrown to the gap between the fixed blade 12 and the movable blade 13 in the cutting process, and the hair cutting efficiency is improved.

In some embodiments of the present invention, each movable blade 13 may be slidably connected to the housing 11; or each movable blade 13 is slidably connected with the corresponding fixed blade 12. Specifically, when the driving member 16 is disposed on the movable blade 13, the movable blade 13 can slide linearly along the housing 11 or the fixed blade 12, and the stability of the movement of the movable blade 13 can be improved.

In this embodiment, as shown in fig. 2, the driven portion 130 may be a rounded flange on the movable blade 13.

In some embodiments of the present invention, as shown in fig. 9-12, the driven portion 130 may also be a roller provided on the movable blade 13. Specifically, the end surface 160 of the driving member 16 contacts with the roller, and the moving blade 13 is driven by the roller, so that the friction force generated when the driving member 16 drives the moving blade 13 can be reduced.

In another embodiment of the present invention, as shown in fig. 13 to 15, the number of the driving members 16 is N-1, that is, the number of the driving members 16 is 4, and one driving member 16 is disposed between two adjacent movable blades 13, in this case, the driving mechanism further includes at least 2 elastic restoring members 22 distributed along the axial direction of the rotating shaft 15, at least one elastic restoring member 22 is located between the housing 11 and the first movable blade, and at least one elastic restoring member 22 is located between the housing 11 and the nth movable blade 13. Specifically, in this embodiment, the driving mechanism further includes 2 elastic resetting pieces 22, one elastic resetting piece 22 is located between the first movable blade and the housing 11, and the other elastic resetting piece 22 is located between the fifth movable blade and the housing 11. Specifically, the elastic restoring member 22 applies a force toward the middle of the cutting device to the first movable blade and the fifth movable blade at the two ends, so that the first movable blade and the fifth movable blade are respectively abutted against the driving members 16 which can be contacted with each other, thereby achieving the purpose that one driving member 16 drives two movable blades.

For the same reason, in some embodiments of the present invention, the moving directions of two adjacent moving blades 13 may be opposite, and the driving members are all symmetric driving members, it is understood that, with reference to fig. 15, in 5 moving blades 13, a part of the adjacent moving blades 13 have opposite moving directions, and another part of the adjacent moving blades 13 have the same moving direction, and accordingly, a part of the driving members 16 at this time is symmetric driving members, another part is asymmetric driving members, the moving blades 13 on both sides of the symmetric driving members 16 have opposite moving directions, and the moving blades 13 on both sides of the asymmetric driving members 16 have the same moving direction. It should be noted that the structures of the symmetric driving member and the asymmetric driving member 16 and the driving principle of the movable blade 13 in this embodiment are the same as those in fig. 12, and the details of this embodiment are not repeated herein.

In another embodiment of the present invention, as shown in fig. 16-18, the number of the driving members 16 is N, that is, the number of the driving members 16 is 5, and each driving member 16 is in linkage engagement with one movable blade 13.
