Description

Technical Field

[0001] This utility model patent relates to the technical field of razors, and more specifically, to a portable double-headed razor. Background Technology

[0002] With the fast pace of life, people seek convenience and speed in shaving, making electric double-headed shavers a common household item for men. Electric double-headed shavers typically consist of a body assembly and a head assembly. The head assembly has two shaver heads, which are driven by a motor located within the body assembly.

[0003] In the prior art, the head cover assembly is detachably connected to the body assembly via a snap-fit ​​structure. However, the snap-fit ​​structure is prone to falling off. For example, when a double-headed shaver is carried out, the head cover assembly is prone to falling off the body assembly due to vibration, bumps, or other reasons. The snap-fit ​​structure is also prone to loose engagement, resulting in an unsecured connection between the head cover assembly and the body assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a portable double-headed shaver, which aims to solve the problem that the head cover assembly and body assembly of the existing double-headed shaver are not firmly connected.

[0025] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0026] A portable dual-head shaver includes a body assembly 200 and a head cover assembly 100. The head cover assembly 100 is located at the top of the body assembly 200 and is detachably connected to the body assembly 200. The head cover assembly 100 includes an upper housing 101, two blade assemblies 102 disposed within the upper housing 101, and a blade holder 103 for supporting the blade assemblies 102. The blade holder 103 has a receiving cavity in the middle, and a first magnet 104 is disposed within the receiving cavity.

[0027] The top of the body assembly 200 is provided with a beard compartment 210, and below the beard compartment 210 is a gear cover 220. The center of the gear cover 220 is recessed inward to form a mounting cavity, and a second magnet 221 is provided in the mounting cavity. The second magnet 221 and the first magnet 104 attract each other. The first magnet 104 and the second magnet 221 are attracted by opposite poles.

[0028] This embodiment provides a portable dual-head shaver. By setting a first magnet 104 in the blade holder 103 of the head cover assembly 100 and a second magnet 221 at the top of the body assembly 200, the first magnet 104 and the second magnet 221 attract each other, thereby greatly enhancing the firmness between the head cover assembly 100 and the body assembly 200 and reducing the possibility of the head cover assembly 100 falling off the body assembly 200.

[0029] The first magnet 104 and the second magnet 221 can be cylindrical permanent magnets.

[0030] The beard storage component 210 has an upwardly protruding outer periphery forming an outer peripheral flange 211. The beard storage component 210 has a disc-shaped structure with a low center and high edges, which facilitates the storage of beard debris. The outer side wall of the beard storage component 210 has multiple protrusions 212, and the inner side wall of the upper housing 101 has multiple recesses. The protrusions 212 and the recesses cooperate with each other, so that the upper housing 101 and the beard storage component 210 can be detachably connected.

[0031] The outer peripheral flange 211 of the beard storage component 210 has a notch to facilitate cleaning beard debris from the beard storage component 210.

[0032] Specifically, the machine body assembly 200 includes a frame 230, a motor 240 located in the middle of the frame 230, and batteries 250 located on both sides of the motor 240. The batteries 250 are used to power the motor 240 and can be rechargeable lithium batteries. The frame 230 is provided with a drive assembly for driving the cutter head assembly 102, and the drive assembly is driven by the motor 240.

[0033] The drive assembly includes a drive gear 261, driven gears 262 located on both sides of the drive gear 261, and a rotating shaft 263 fixedly connected to the driven gears 262. The driven gears 262 mesh with the drive gear 261, and the rotating shaft 263 passes through the driven gears 262. When the motor 240 drives the drive gear 261 to rotate, it drives the driven gears 262 to rotate, and the rotating shaft 263 rotates accordingly. One drive gear 261 simultaneously drives the two driven gears 262 located on its left and right sides to rotate, thereby driving the two cutter head assemblies 102 to work.

[0034] The drive assembly is located on the top of the frame 230. A gear cover 220 covers the driven gear 262, and the upper part of the rotating shaft 263 passes sequentially through the gear cover 220 and the whisker-shaped storage unit 210. The top of the frame 230 has a drive gear slot and a driven gear slot, with the drive gear 261 and driven gear 262 respectively housed in the drive gear slot and driven gear slot. A insertion hole is also provided in the center of the driven gear slot, into which the bottom end of the rotating shaft 263 is inserted. The diameter of the rotating shaft 263 is smaller than the inner diameter of the insertion hole to facilitate the rotation of the rotating shaft 263.

[0035] The top of the rotating shaft 263 is provided with a positioning element 271, and the upper part of the positioning element 271 is provided with a rotating head 272. The bottom of the cutter head assembly 102 is provided with a mating hole, and the rotating head 272 is embedded in the mating hole. The cross-section of the top of the rotating shaft 263 is non-circular, and the positioning element 271 has a non-circular positioning hole. The top of the rotating shaft 263 is inserted into the positioning hole, thereby ensuring that the positioning element 271 will not rotate relative to the rotating shaft 263.

[0036] The rotating head 272 is equipped with a compression spring 273 inside. The top end of the compression spring 273 abuts against the inner wall of the rotating head 272, and the bottom end of the compression spring 273 abuts against the positioning member 271. On the one hand, the compression spring 273 can counteract part of the vibration of the blade assembly 102. On the other hand, it allows the blade assembly 102 to have a certain self-adaptive space, which facilitates close shaving with the blade assembly 102.

[0037] The outer wall of the positioning component 271 is provided with a groove 2710, and the inner wall of the rotating head 272 is provided with a guide block 2720. The guide block 2720 protrudes from the inner wall of the bottom end of the rotating head 272 and can slide up and down within the groove 2710. When the rotating head 272 is subjected to downward pressure, the compression spring 273 continues to be compressed, and the guide block 2720 slides downward within the groove 2710; when the pressure decreases or disappears, the guide block 2720 slides upward within the groove 2710 due to the restoring force of the compression spring 273.

[0038] A sealing gasket 280 is provided below the gear cover 220, and the sealing gasket 280 is located above the driven gear 262. The rotating shaft 263 passes through the sealing gasket 280. Near the rotating shaft 263, the sealing gasket 280 forms an annular groove, which is arranged around the rotating shaft 263. The arrangement of the sealing gasket 280 can prevent water, beard debris, etc. from falling into the driven gear 262 and avoid clogging.

[0039] The bottom of the body assembly 200 has a charging port 290, which can be a universal Type-C interface. This eliminates the need for an additional charging cable and adapter; the shaver can be charged directly using a Type-C charging cable commonly found in the user's home, avoiding waste and saving costs. The charging port 290 also facilitates charging of the battery 250 inside the body assembly 200, providing power for the shaver's operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
