[0032] At present, the waterproof performance of the blade body is obviously insufficient, and moisture can easily enter the inside of the shaver through various gaps, which can easily cause the internal electrical structure such as the motor and the circuit board to be damp or short-circuited, thereby causing faults and shortening the service life of the product.

[0033] Please refer to Figures 1 to 7 The shaver waterproof structure provided in the embodiment comprises a shell 100, a first waterproof piece 200 and a key assembly 300.

[0034] The shell 100 is internally formed with a device groove 110 having a groove opening, and the sidewall of the shell 100 is provided with a mounting opening in communication with the device groove 110. The first waterproof piece 200 is arranged in the device groove 110 and has a partition portion 210 and a mounting portion 220. The sidewall of the partition portion 210 is in close contact with the inner wall of the device groove 110 and is enclosed with the inner wall and the bottom wall of the device groove 110 to form a first space. The mounting portion 220 is in close contact with the inner wall of the device groove 110, and the mounting portion 220 is provided with a receiving hole in communication with the mounting opening and used for abutting against the circuit board. The key assembly 300 is inserted into the mounting opening and passes through the receiving hole. One end of the key assembly 300 is located in the mounting opening, the other end abuts against the circuit board, and the key assembly 300 abuts against the inner sidewall of the mounting opening and the inner sidewall of the receiving hole.

[0035] In the embodiment, the device groove 110 is formed in the shell, and electrical elements such as the circuit board and the battery of the electric shaver are arranged in the device groove 110. The sidewall of the partition portion 210 of the first waterproof piece 200 is in close contact with the inner wall of the device groove 110 and is enclosed with the inner wall and the bottom wall of the device groove 110 to form a first space, thereby effectively preventing external moisture from entering the device groove 110.

[0036] In addition, the key assembly 300 of the electric shaver in the embodiment is arranged in the mounting opening of the shell 100 and is inserted into the receiving hole. The key assembly 300 is connected with the electrical components in the device groove 110.

The key 310 is arranged in the sealing member 320 to abut against the circuit board, and the key 310 is made of elastic material and the side wall thereof is attached to the inner side wall of the mounting hole.

[0045] The side wall of the sealing member 320 is attached to the inner wall of the accommodating hole to form a waterproof barrier, so as to avoid water inflow into the equipment slot 110 due to the existence of a large gap between the key 310 and the accommodating hole.

[0046] Specifically, the key 310 in the embodiment itself has a certain elasticity, and the other end of the key 310 can be pressed to touch the circuit board to control the electric shaver.

[0047] In the embodiment, the key assembly 300 further comprises a filler 400. The filler 400 is arranged between the accommodating hole and the mounting hole, and the filler 400 is provided with a connecting hole in communication with the mounting hole and the accommodating hole respectively. One end of the filler 400 is in abutment with the shell 100, and the other end of the filler 400 is arranged at the joint of the sealing member 320 and the first waterproof member 200.

[0048] The filler 400 can ensure the sealing between the sealing member 320 and the shell, and the filler 400 covers the joint of the sealing member 320 and the first waterproof member 200, so that water can be prevented from entering the gap between the sealing member 320 and the first waterproof member 200.
