Embodiment 1

[0022] like figure 1 As shown, the present invention is used for the waterproof and dustproof equipment of mobile power supply USB socket, comprises the waterproof layer 1 that is connected with the outer wall of mobile power supply, and the side wall of described waterproof layer 1 facing mobile power supply is covered with adhesive layer 2, and described Both the waterproof layer 1 and the adhesive layer 2 are provided with openings 3 that communicate with and adapt to the USB socket of the mobile power supply. The side wall of the waterproof layer 1 facing the mobile power supply is connected with a dustproof layer 4. The dustproof layer A vertex 5 of 4 is rotatably connected with the waterproof layer 1, and the other end of the dustproof layer 4 opposite to the vertex 5 is provided with a bump 6, and the bump 6 faces the waterproof layer 1, and the waterproof layer 1 is provided with a bump 6 The block 6 fits into the groove 7 of the connection. The dustproof layer 4 is c...

Embodiment 2

[0025] Based on Example 1, the waterproof layer 1 includes the following components: EPDM rubber, neoprene rubber, butyl rubber, chlorinated polyethylene resin, anti-mold and bactericide, high-density polyethylene, waste tire rubber powder.

[0026] Waterproof material with EPDM rubber, neoprene rubber, butyl rubber, and chlorinated polyethylene resin blend as the main material. It has the characteristics of both plastic and rubber, and has the characteristics of high strength, high elongation, long service life, light weight and good adhesion. Due to the saturation of the molecular structure of chlorinated polyethylene and the introduction of chlorine atoms, the main chain is not easy to break under the action of oxygen, ozone, sunlight, humidity and heat, so the product has excellent weather resistance and flame retardancy. And the construction and maintenance are simple; high-density polyethylene is insoluble in any organic solvent, resistant to acid, alkali and various sal...

Embodiment 3

[0028] Based on the above embodiment, the dustproof layer 4 includes the following components: vegetable oil, potassium hydroxide, glycerin, polyoxyethylene·polyoxypropylene ether, ethanol, polyacrylate emulsion film-forming agent.

[0029] The anti-dust agent made of vegetable oil, potassium hydroxide, glycerin, and polyoxyethylene·polyoxypropylene ether as the main agent has low cost and simple process, and the polyacrylate emulsion film-forming agent is the main film-forming substance.

Abstract

The invention discloses waterproof and dustproof equipment for a mobile power supply USB interface, and the equipment comprises a waterproof layer connected with an outer wall of a mobile power supply. A side wall, facing the mobile power supply, of the waterproof layer is coated with an adhesive layer. The waterproof layer and the adhesive layer are respectively provided with an opening which is connected with and adaptive to the mobile power supply USB interface. A side wall, facing the mobile power supply, of the waterproof layer is connected with a dustproof layer. One top corner of the dustproof layer is rotatingly connected with the waterproof layer, and the other end, opposite to the top corner, of the dustproof layer is provided with a convex block. The convex block faces the waterproof layer, and the waterproof layer is provided with a groove which is in cooperative connection with the convex block. According to the invention, the waterproof and dustproof layers are pasted outside the mobile power supply USB interface, and the equipment can achieve the effective water and dust resistance for the mobile power supply, thereby prolonging the service life of the mobile power supply USB interface.

Description

technical field [0001] The invention relates to a waterproof and dustproof device, in particular to a waterproof and dustproof device for a USB socket of a mobile power supply. Background technique [0002] Mobile power, also known as "external battery", "external battery", "backup battery", "digital charging companion", "power bank" and "mobile power" are developed with the popularization and rapid growth of digital products. Its definition is: a portable power supply that is convenient and easy to carry. As the functions of digital products are increasingly diversified, they are used more frequently, and they are more and more closely related to our daily life. How to increase the use time of digital products, facilitate people's lives, replenish power in time, and play their best functions is even more important. without delay. Mobile power supply is the best solution to solve this problem. Carrying a mobile power supply with you can charge a variety of digital products...
