[0029] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0030] A waterproof shaver includes a body assembly 200 and a head cover assembly 100. The head cover assembly 100 is disposed 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.

[0031] The body assembly 200 contains a motor 240, a battery 250, and a circuit board. The motor 240 drives the blade assembly 102 to rotate. Both the motor 240 and the circuit board are electrically connected to the circuit board. The housing of the body assembly 200 has a button section 201. The body assembly 200 contains a button circuit board assembly 202. The button section 201 and the button circuit board assembly 202 correspond to each other. A sealing gasket 203 is provided between the button section 201 and the button circuit board assembly 202. The button circuit board assembly 202 is electrically connected to the circuit board.

[0032] This embodiment provides a waterproof shaver. By providing a sealing gasket 203 between the button part 201 and the button circuit board assembly 202 of the shaver, the gasket prevents water from entering the button circuit board assembly 202 through the gap between the button part 201 and the housing of the body assembly 200. This allows the body assembly 200 near the button part 201 to also be rinsed with water, making the shaver easier to clean and providing a better cleaning effect.

[0033] The inner wall of the button part 201 is recessed outward to form a fixing hole 2011. The sealing gasket 203 has a positioning protrusion on the side facing the button part 201. The positioning protrusion is embedded in the fixing hole 2011, which plays a positioning and fixing role, so that the sealing gasket 203 will not deviate from its original position due to pressure, thereby ensuring the waterproof performance of the sealing gasket 203.

[0034] The button section 201 is provided with a filling hole 2012, and a transparent filler is provided in the filling hole 2012. The transparent filler can be transparent plastic, transparent resin, transparent silicone, etc., to facilitate light transmission. The button circuit board assembly 202 is provided with an indicator light 2021, which corresponds to the filling hole 2012. The sealing gasket 203 is a transparent gasket or a semi-transparent gasket. In this way, the light of the indicator light 2021 can pass through the sealing gasket 203 and the transparent filler in sequence, thereby reflecting the working status or charging status of the shaver. At the same time, it can also prevent water from seeping into the indicator light 2021 when the body assembly 200 is washed with water, which could damage the shaver.

[0035] A laser hole is made at the button part 201 corresponding to the bottom of the filling hole 2012, so that when water is rinsed, water will not enter the filling hole 2012 through the laser hole, while light can pass through the laser hole.

[0036] The button part 201 can be made of materials such as zinc alloy, aluminum alloy, and stainless steel, which are not easy to wear and rust.

[0037] The head cover assembly 100 includes an upper housing 101, two cutter head assemblies 102 disposed within the upper housing 101, and a cutter holder 103 for supporting the cutter head assemblies 102. The cutter holder 103 has a receiving cavity in the middle, and a first magnet 104 is disposed in the receiving cavity.

[0038] 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 gear cover 220 has an inwardly recessed middle portion forming a mounting cavity, within which a second magnet 221 is provided. The second magnet 221 attracts the first magnet 104. The first magnet 104 and the second magnet 221 are opposite poles and attract each other. The first magnet 104 and the second magnet 221 can be cylindrical permanent magnets. By placing the first magnet 104 in the blade holder 103 of the head cover assembly 100 and the second magnet 221 at the top of the body assembly 200, the mutual attraction between the first magnet 104 and the second magnet 221 greatly enhances the stability of the head cover assembly 100 and the body assembly 200, reducing the possibility of the head cover assembly 100 detaching from the body assembly 200.

[0039] A sealing gasket 280 is provided below the gear cover 220, which allows the head cover assembly 100 to be removed and rinsed with water, and the head of the body assembly 200 can also be rinsed with water.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] At the charging port 290, the body assembly 200 has an inwardly recessed receiving groove, within which is a ring-shaped pad 291, the center of which faces the charging port 290. The center of the ring-shaped pad 291 is empty, facilitating the insertion of the charging cable into the charging port 290. The thickness of the ring-shaped pad 291 is not less than the depth of the receiving groove, and typically the top of the ring-shaped pad 291 may be slightly higher than its surrounding housing, thus preventing water from easily flowing down the housing of the body assembly 200 into the charging port 290 when the shaver is washed. Furthermore, the ring-shaped pad 291 can be a silicone pad, rubber pad, etc., possessing a certain degree of elasticity, providing some protection for the charging port 290.

[0049] Furthermore, a rubber stopper can be detachably embedded in the middle of the annular pad 291. The rubber stopper can completely seal the charging interface 290. When the shaver needs to be charged, the rubber stopper can be removed to charge the shaver. In addition, a connector can be provided at one end of the rubber stopper. One end of the connector is connected to the rubber stopper, and the other end is connected to the annular pad 291, thereby avoiding the risk of the rubber stopper being easily lost.

[0050] 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.
