[0044] The present invention is further described in detail below in conjunction with specific embodiments, but the structure of the present invention is not limited to the following embodiments.

[0045] like Figures 1 to 7 As shown, a blade net 34 moving multi-head shaver includes an upper body module 10, a lower body module 20, a blade head module 30, a blade drive assembly 40, a lower body blade net drive assembly 50, a blade net drive motor 60 and a movable blade drive motor 70. The upper body module 10 and the lower body module 20 are detachably connected, and the detachable connection can be achieved by magnet adsorption or buckle longitudinal plug-in.

[0046] The cutter head module 30 is arranged on the upper body module 10, and includes a central cutter head module 31 and a surrounding cutter head module 32. The central cutter head module 31 is arranged at the center of the upper body module 10, and two or more surrounding cutter head modules 32 are arranged around the center of the upper body module 10. In order to make the surrounding cutter head modules 32 more suitable for the arc structure of the skin, the surrounding cutter head modules 32 are arranged tilted toward the center direction of the upper body module 10. The central cutter head module 31 and the surrounding cutter head module 32 include a cutter head housing 33, a knife net 34 and a moving blade 35. The cutter head housing 33 is connected to the upper body module 10 and remains stationary. The knife net 34 can be rotatably plugged into the inner side of the cutter head housing 33. The central cutter head module 31 and the knife nets 34 of the surrounding cutter head module 32 are mutually connected by transmission. The knife net 34 of the central cutter head module 31 can be meshed with the knife nets 34 of each surrounding cutter head module 32 through the knife net gear 38. By driving the knife net 34 of the central cutter head module 31 or any knife net 34 of the surrounding cutter head module 32, power transmission is realized to drive all the knife nets 34 to rotate. The transmission connection method can be to use a gear to connect the knife net 34, or to preset a base for connecting the knife net 34, connect the gear to the base of the knife net 34, and the moving blade 35 is coaxially arranged with the knife net 34.

[0047] The blade drive assembly 40 includes a cutter head steering knuckle 41 and a moving blade transmission shaft 42. The cutter head steering knuckle 41 is arranged in the lower fuselage module 20. The cutter head steering knuckle 41 is provided with an extended end 45. The extended end 45 of the cutter head steering knuckle 41 extends out of the lower fuselage module 20 and corresponds to and is transmission-connected with the moving blades 35 surrounding the cutter head module 32 one by one. The moving blade transmission shaft 42 is transmission-connected with the power output end of the moving blade drive motor 70. Specifically, the blade gear 44 can be arranged on the cutter head steering knuckle 41 and the blade gear 44 can be arranged on the moving blade transmission shaft 42. The blade gear 44 arranged on the moving blade transmission shaft 42 is respectively meshed with the blade gears 44 arranged on each cutter head steering knuckle 41, or the blade gear 44 arranged on the moving blade transmission shaft 42 and the gears of each cutter head steering knuckle 41 are arranged. Then, an additional blade gear 44 is arranged between the blade gear 44 arranged on the moving blade transmission shaft 42 and the gears of each cutter head steering knuckle 41, so as to transmit power to the moving blade 35 of the central cutter head module 31.

[0048] The lower fuselage knife net drive assembly 50 includes a knife net output gear 51 and a knife net power output ring 52. The knife net output gear 51 is arranged in the height range where the knife head steering knuckle 41 is located in the lower fuselage module 20. The knife net power output ring 52 is detachably connected to the knife net 34 of the central knife head module 31, and the knife net power output ring 52 is coaxially arranged with the moving blade drive shaft 42.

[0049] The power output end of the knife net driving motor 60 can extend into the longitudinal space between any two surrounding knife head modules 32 through the rotating shaft and be connected to the knife net output gear 51 through transmission.

[0050] The movable blade driving motor 70 is transmission-connected to the cutter head steering knuckle 41 of the blade driving assembly 40 via a gear set.

[0051] According to the above structure, during the movement of the knife net 34 moving multi-head shaver, the power supply of the knife net 34 moving multi-head shaver is turned on, and the knife net drive motor 60 and the movable blade drive motor 70 are driven to work respectively. The power output end of the movable blade drive motor 70 drives the blade gear 39 set on the knife head steering knuckle 41 and the blade gear 39 set on the movable blade drive shaft 42 through the rotation of the gear group, and then drives the knife head steering knuckle 41 and the movable blade drive shaft 42 to rotate. The protruding end 45 of the knife head steering knuckle 41 and the movable blade drive shaft 42 correspond to the movable blade 35 one by one and are plugged into the movable blade 35, so as to realize the rotation of the movable blade 35 in the working state.

[0052] At the power output end of the blade net drive motor 60, the power is extended from the space between the blade head modules 32, and then connected to the blade net output gear 51 at the height of the blade head knuckle 41, thereby driving the blade net power output ring 52 coaxially arranged with the moving blade drive shaft 42 to rotate. The top area of ​​the blade net power output ring 52 is engaged with the bottom area of ​​the blade net 34, and drives the blade net 34 to rotate. During the rotation of the blade net 34, the power is transmitted between the central blade head module 31 and the blade nets 34 surrounding the blade head module 32 through the gear, driving each blade net 34 to rotate. When the blade net 34 rotates, vibration is generated. The blade net 34 that is always in rotation avoids contacting the skin with static friction while remaining stationary. The resistance to sliding on the skin is reduced by dynamic friction, and the skin on the contact surface is vibrated in conjunction with the rotational movement, which has the effect of massaging the skin. In addition, it is easier to push the skin than the skin pushed by the blade net 34 at rest, thereby improving the comfort during the use of the shaver.

[0053] like Figures 1 to 7 As shown, preferably, the knife net 34 of the central knife head module 31 is transmission-connected with the knife net 34 of the surrounding knife head module 32 by means of gear meshing transmission, and the gear is arranged on the outer side of the knife net 34 .

During the movement of the blade drive assembly 40, the top of the cutter head knuckle 41 abuts through the extended end 45, and the bottom is subjected to elastic force through the abutting spring 43, so that the transmission of the cutter head knuckle 41 and the moving blade transmission shaft 42 is always maintained in a fixed range, ensuring the stability of power transmission.

[0055] like Figures 1 to 7 As shown, preferably, the upper fuselage module 10 and the lower fuselage module 20 are buckled together and detachably connected via magnets.

[0056] like Figures 1 to 7 As shown, preferably, the lower body knife net drive assembly 50 further includes a yield gear 53, and the power output end of the knife net drive motor is transmission-connected to the knife net output gear 51 via the yield gear 53.

[0057] like Figures 1 to 7 As shown, preferably, it also includes a knife net knuckle 36, one end of which is connected to the knife net 34, and the other end is transmission-connected to the adjacent central knife head module 31 and the surrounding knife head module 32 through gears.

[0058] like Figures 1 to 7 As shown, preferably, the upper fuselage module 10 is provided with a slag discharge hole 11, and the slag discharge hole 11 is connected with the inner side of the central cutter head module 31 and the knife net 34 surrounding the cutter head module 32. In actual use, the residues cut by the knife net 34 and the movable blade 35 move against each other, enter the inner side of the knife net 34, and then fall between the upper fuselage module 10 and the lower fuselage module 20 through the slag discharge hole 11, so that the residues can be cleaned when the upper fuselage module 10 and the lower fuselage module 20 are disassembled, and the inner side of the upper fuselage module 10 can be cleaned through the slag discharge hole 11.

[0059] like Figures 1 to 7 As shown, preferably, the cutter head module 30 further comprises a blade base 37, the movable blade 35 is connected to the blade base 37, and the blade base 37 is transmission-connected to the extended end 45 of the cutter head knuckle 41 or the movable blade transmission shaft 42. By providing the blade base 37, it is convenient to ensure the stability of the movable blade 35 during use.

[0060] In the above embodiment, the transmission gear of the knife net 34 surrounding the knife head module 32 can be tilted and rely on the bevel gear to transmit power, or the power can be transmitted by setting an annular universal joint between the preset base and the knife net 34.

[0061] In the above embodiment, the cutter head steering knuckle 41 and the cutter net steering knuckle 36 can adopt an annular frame structure, or a structure that fits together, and rely on the side contact or hooking of the annular structure or the interlocking structure to transmit power, and the inclination of the power transmission direction is achieved by setting gaps between the annular frames, and the center of the annular structure is convenient for the protruding end 45 or the moving blade drive shaft 42 to pass through.

[0062] In the above embodiment, in order to adapt the distance between the knife net output gear 51 and the knife net power output ring 52, a gear may be added between the knife net output gear 51 and the knife net power output ring 52 to transmit the gear power.

[0063] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
