Mobile phone shell based on mobile phone film gap cold suction type ash removal

Abstract

The invention discloses a mobile phone shell based on mobile phone film gap cold suction type ash removal. The invention belongs to the technical field of electronic products, according to the scheme,a movable rod is pulled outwards, the movable rod is promoted to bring part of ammonium chloride powder into the external wrapping frame to be mixed with barium hydroxide octahydrate powder; under the stirring effect of the movable rod, the ammonium chloride powder is promoted to react with the barium hydroxide octahydrate powder; a large amount of ammonia gas can be generated during refrigeration; refrigeration, the water vapor is promoted to liquefy on the inclined surface embedded into the incision sac to form small liquid drops; on the other hand, the generated ammonia gas is used, according to the method, the barium hydroxide octahydrate powder and the ammonium chloride powder can be scattered, so that the reaction efficiency of the ammonium chloride powder and the barium hydroxide octahydrate powder is improved, and meanwhile, the embedded cutting bag can be promoted to expand, so that an edge gap between the smart phone and the tempered film is filled by the embedded cutting bag, and dust on the surface of the smart phone and the tempered film is adsorbed.

Description

technical field [0001] The invention relates to the technical field of electronic products, and more specifically relates to a mobile phone case based on a cold-absorption type dust removal method based on a gap in a mobile phone film. Background technique [0002] Mobile phone, the full name of mobile phone or wireless phone, usually called mobile phone, was originally just a communication tool, and it was commonly known as Big Brother in the early days. It is a portable phone terminal that can be used in a wide range. The field mobile phone manufactured in 1940 was developed. In 1958, Soviet engineer Leonid Kuprianovich invented the ЛК-1 mobile phone. In 1973, American Motorola engineer Martin Cooper invented The world's first commercial mobile phone has gone through the 2G era and the 3G era, so far it has developed to the 4G era, and the 5G era has followed closely. 5G commercial use has already appeared in China. [0003] Smart phone (Smart phone) refers to an independ...

Problems solved by technology

[0004] After the existing smart phone is pasted with a film, because there is a gap between the edge of the tempered film on both sides and the screen of the mobile phone, a large amount of dust will be stored in the gap, which will affect the use and may gradually promote the film to be separated from the screen. mobile phone screen separation
