Description

Technical Field

[0001] The utility model relates to the technical field of demisting, and in particular to a demisting component based on graphene. Background Art

[0002] When mirror products such as bathroom mirrors and car rearview mirrors enter a relatively high temperature and humidity environment from a low temperature, a layer of water mist will form on the mirror surface, making the mirror surface blurry and unusable. In particular, when the mirror surface of the car rearview mirror forms water mist and becomes blurry, it will cause a great safety hazard in car driving, so it is very important to defog the mirror surface. At present, the main defog method is to set a heating component on the back of the mirror. For example, Chinese patent document No. CN 218870121 U disclosed a bathroom cabinet mirror defog structure on April 18, 2023, including a bathroom cabinet located on the ground, a bathroom mirror is suspended on the top of the bathroom cabinet, the bathroom mirror includes a mounting frame, and an LED fill light strip is installed on the front of the mounting frame; the bathroom cabinet includes a cabinet body, and a white rock board countertop is installed on the top of the cabinet body; the LED fill light strip is embedded and connected with a silver mirror, and a control panel is also installed in the middle of the bottom of the LED fill light strip. The back of the silver mirror is bonded and connected with an electric heating film, and the electric heating film is electrically connected to the defog switch.

[0003] However, due to the humid environment in bathrooms and rainy days, there is generally no waterproof structure between the electric heating film of this mirror defog structure and the wires of the components electrically connected to it, and the electric heating film and the wires are fixed by flat spot welding. Therefore, the connection position between the electric heating film and the wires is easily damaged by moisture, and the wires electrically connected to the electric heating film are easily pulled off, which shortens the service life of the product. Therefore, there is room for improvement. Utility Model Content

[0030] A waterproof sealing structure is provided at the penetration position of the wiring terminal 51 , and the waterproof sealing structure includes a sealant 6 . The sealant 6 is provided on the other side of the base film 1 , and the sealant 6 covers the wiring terminal 51 and the position penetrating the base film 1 .

Preferably, the inner side wall of the wire groove 72 can be provided with a connecting glue to further prevent the conductive wire 5 from shaking.

[0034] The waterproof sealing structure further includes an insulating tape 8 disposed on the other side of the back film 4 , wherein the insulating tape 8 covers the connection terminal 51 and penetrates the back film 4 .
