Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This application provides a blade reciprocating assembly, which includes a connecting seat 1. A boss 11 is provided in the inner cavity of the connecting seat 1. Two parallel sliding grooves 12 are provided on the end face of the boss 11 near the inner cavity of the connecting seat 1. A moving member 2 is provided on the boss 11, and the moving member 2 includes two parallel sliding rods 21. Each sliding rod 21 is slidably disposed within the sliding groove 12, and the sliding direction is along the axis of the sliding rod 21. A bearing seat 22 is provided between each sliding rod 21, and the bearing seat 22 is located above the sliding rod 21. A [missing information - likely a design feature] is provided on the end face of the bearing seat 22 facing away from the sliding rod 21. Several retaining members 23 are provided, each retaining member 23 for connecting the blade assembly 101. In addition, a transmission groove 24 is provided on the end face of the support 22 near the slide bar 21. The length direction of the transmission groove 24 is perpendicular to the sliding groove 12. The driving component extends into the transmission groove 24. When the driving component is running, it alternately pushes the side walls of the transmission groove 24 on both sides of the driving component. The transmission groove 24 drives the moving component 2 to reciprocate along the direction of the sliding groove 12. The slide bar 21 cooperates with the sliding groove 12 to further limit the movement trajectory of the moving component 2. The blade assembly 101 connected to the retaining member 23 operates to perform shaving operations.

[0031] It should be noted that the blade assembly 101 includes a blade for shaving and a foil covering the blade that contacts the skin. The retainer 23 is connected to the blade and drives the blade to swing back and forth within the foil.

[0032] Please refer to the instruction manual appendix. Figure 2 With appendix Figure 5A connecting hole 15 is provided between each sliding groove 12. The connecting hole 15 penetrates the boss 11 along the height direction of the boss 11. Correspondingly, symmetrical sliding blocks 25 are provided on the opposite side walls of the bearing seat 22. Each sliding block 25 is arranged along the extension direction of the slide rod 21 and is located on the side of the bearing seat 22 away from the holding member 23. Each sliding block 25 extends into the connecting hole 15. When the slide rod 21 slides in the sliding groove 12, the bearing seat 22 drives the sliding blocks 25 to slide in the groove 12. The sliding rod 21 slides within the connecting hole 15. Preferably, both inner sidewalls of the connecting hole 15 along its length are arc surfaces. When the sliding rod 21 moves to one end of the sliding groove 12, the sliding block 25 on that side fits against the corresponding arc surface. Furthermore, the width of the connecting hole 15 is equal to the width of the sliding block 25. The cooperation between the sliding block 25 and the connecting hole 15 further limits the direction of movement of the moving part 2 and also prevents the sliding groove 12 from being too shallow, which would cause the sliding rod 21 to slide out of the sliding groove 12 and the moving part 2 to deviate.

[0033] Preferably, the length of the sliding groove 12 is greater than the length of the sliding rod 21, and the length difference between the sliding rod 21 and the sliding groove 12 is the moving distance of the moving part 2. The length of the sliding rod 21 can be adjusted according to the size of the blade assembly 101 to ensure that the blade can fully scrape the beard extending into the blade net.

[0034] Please refer to the instruction manual appendix. Figure 3 Each sliding block 25 has a conical surface on its corresponding end face. The bending directions of each conical surface are opposite. When the user disassembles the connecting seat 1 and cleans it regularly, the drive assembly needs to be inserted into the transmission groove 24 again. During the process of the drive assembly being inserted into the transmission groove 24, the conical surface of each sliding block 25 abuts against the end of the drive assembly. The conical surface guides the drive assembly into the designated position in the transmission groove 24. In addition, in the process of assembling the connecting seat 1 and the transmission assembly, the conical surface of the sliding block 25 simplifies the assembly operation and improves the production rate.

[0035] This application also provides a razor with the aforementioned blade reciprocating assembly. The razor also includes a handle, comprising a first housing 31 and a second housing 32. Specifically, both the first housing 31 and the second housing 32 are semi-cylindrical shells cut along a cylindrical axis. A plurality of latches are evenly distributed along the two edges of the first housing 31 port along the length of the handle. Correspondingly, a plurality of slots are evenly distributed along the two edges of the second housing 32 port along the length of the handle. The ports of the first housing 31 and the second housing 32 are joined, with each latch engaging with a corresponding slot to securely connect the first housing 31 and the second housing 32. A top plate, specifically semi-circular, is provided at the same end of both the first housing 31 and the second housing 32. The opposing edges of the top plates of the first housing 31 and the second housing 32 can be riveted together to close one end of the handle. A bottom plate, specifically circular, is provided at the end of the second housing 32 opposite to the top plate. The edge of the circular plate abuts against the inner wall of the first housing 31, closing the other end of the handle.

[0036] Please refer to the instruction manual appendix. Figure 1 Appendix Figure 6 With appendix Figure 7 A cover plate 5 is provided at the top plate of the handle. The cover plate 5 has a mating groove on the side near the top plate. The end of the handle with the top plate extends into the mating groove of the cover plate 5. A fastening screw is installed on the end face of the cover plate 5 to fix the cover plate 5 to the handle. A snap-fit ​​groove 51 is provided on the side wall of the cover plate 5. The snap-fit ​​groove 51 is specifically an L-shaped groove. Correspondingly, a connecting groove 13 is provided on the side of the connecting seat 1 near the handle. A connecting block 14 extends from the inner side wall of the connecting groove 13. The vertical part of the snap-fit ​​groove 51 of the cover plate 5 is aligned with the connecting block 14 of the connecting groove 13, and the cover plate 5 is inserted into the connecting groove 13. The connecting block 14 slides along the vertical part of the snap-fit ​​groove 51. When the connecting block 14 reaches the bottom of the vertical part of the snap-fit ​​groove 51, the handle is turned. The handle drives the cover plate 5 to rotate, so that the connecting block 14 slides to the horizontal part of the snap-fit ​​groove 51. At this time, the handle and the connecting seat 1 are connected, and the snap-fit ​​groove 51 limits the relative position of the connecting seat 1 and the handle. In addition, a fastening bolt can be inserted between the connecting seat 1 and the cover plate 5 to further stabilize the connection between the handle and the connecting seat 1. In addition, the side of the connecting seat 1 away from the handle is connected to the mounting seat 10, and the mounting seat 10 is provided with the blade assembly 101.

[0037] Please refer to the instruction manual appendix. Figure 1 With appendix Figure 4Both the first housing 31 and the second housing 32 have partitions inside their cavities. When the first housing 31 and the second housing 32 are connected, the partitions are linked to separate the handle's inner cavity. Both the partitions and the top plate have through holes, and each through hole is coaxially arranged with the handle's side wall. A control plate 6 is provided on the side of the partition closest to the bottom plate. The cable of the control plate 6 passes through the through hole of the partition and is electrically connected to the rotor 4 on the other side of the partition. The output shaft 41 of the rotor 4 extends out of the through hole of the top plate. A rotating plate is provided on the end face of the output shaft 41, and the rotating plate is coaxially arranged with the output shaft 41. An eccentric shaft 42 is provided on the end face of the rotating plate. The axis of the eccentric shaft 42 is parallel to but not collinear with the axis of the output shaft 41. The eccentric shaft 42 extends away from the handle and passes through the connecting hole 15 into the transmission groove 24 of the bearing seat 22. Preferably, the distance between the axis of the output shaft 41 and the axis of the eccentric shaft 42 is equal to the width of the transmission groove 24, ensuring that when the output shaft 41 rotates, the eccentric shaft 42 can abut against the two side walls of the transmission groove 24 and push the moving part 2 to slide back and forth.

[0038] Preferably, a battery is also provided in the inner cavity near the bottom plate. The battery provides power to the rotor 4 and the control board 6. An LCD screen is also provided on the control board 6 to display power information. A protective cover 7 is provided on the outside of the handle.
