Description

Technical Field

[0001] The invention relates to shaver technology, in particular to an electric shaver with a multi-layer waterproof structure. Background Art

[0002] Razors are self-service tools for shaving, mostly used by adult men. Razors can be divided into three categories according to their structure: safety razors, electric razors, and mechanical razors. Razors are mostly placed in the bathroom, and need to be waterproofed. However, most existing razors do not have built-in waterproofing, which has certain limitations. The waterproof performance of the fully washable electric shaver introduced needs to be multi-layered to prevent water from entering the interior and causing damage to the electric shaver.

[0003] Since the whole body washable electric shaver can wash the whole body, it is convenient to wash the beard residue on the whole body, and the user needs to touch the shaver button when using the shaver after washing. Since the button is a movable structure, there is a gap between the button and the shaver housing. The water stains on the fingers can easily enter the gap of the shaver housing and cause the button to have poor contact, thereby shortening the service life of the shaver. Therefore, we propose a waterproof structure for a shaver to solve this problem. Summary of the invention

The sealing member 20 is installed in the arc groove 64 on the positioning member 12 through the arc body 63, which can simultaneously restrict the sealing member 20 from rotating.

[0058] The positioning member 12 is composed of a disc 65 and a cylinder 66. The diameter of the disc 65 is larger than that of the cylinder 66. The elastic arm 57 is arranged at the lower end of the cylinder 66. The disc 65 is placed at the upper end of the elastic member 13, and the arc groove 64 is arranged on the disc 65.

[0059] A compression gap 40 is formed between the elastic member 13 and the positioning member 12, so that the pressure member 21 can be pushed by the second limit block 34 of the limit member 11, and the limit member 11 is kept pushing the pressure member 21, so that the upper end of the pressure member 21 applies pressure to the upper end of the elastic member 13, causing it to deform, thereby facilitating the installation of the limit member 11.

[0060] The inner wall of the sealing member 20 is provided with a plurality of arc-shaped bodies 63, and the positioning member 12 is provided with an arc-shaped groove 64 that matches the arc-shaped body 63. The arc-shaped groove 64 is located at the upper end of the elastic member 13, and the arc-shaped body 63 is placed on the elastic member 13. When the sealing member 20 is pressed by an external force, the pressing rod 4 can move in the first through hole 18 and the second through hole 22, and the switch assembly 3 at the lower end can be pressed to open, and pressed again to close. The arc-shaped body 63 slides in the arc-shaped groove 64, presses the elastic member 13 at the lower end, and keeps the elastic member 13 under compression.

[0061] like Fig.14As shown, when the seal 20 is installed, the sealing portion 38 on the seal 20 will be kept to push the push end 37, and the limiter 11 will be kept rotating around the hinge shaft 35, so that the second protrusion 25 originally in the first limit opening 43 is pushed by the second limit block 34, so that the upper end of the pressure member 21 is pushed by force, the contact surface 29 at the lower end is kept in contact with the inclined surface 28, and the upper end of the elastic member 13 is kept compressed and deformed. The second protrusion 25 enters the position of the limiter 11 in the first limit opening 43, and the limit end 36 is kept in the limit groove 47, and the sealing portion 38 is pressed and limited, ensuring that the seal 20 is stably installed in the installation hole 7.

[0062] When the elastic part 39 of the sealing member 20 is pressed, the elastic part 39 can be kept deformed by force, and the elastic member 13 can be kept compressed by force. When the external force is removed, the elastic force of the elastic member 13 and the elastic part 39 can keep the pressing rod 4 reset, which is convenient for the next pressing.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
