Problems solved by technology

[0003] After fog and condensation inside the transparent shell of the network camera, the monitoring image is a piece of white flowers. At this time, the monitoring object is in an invalid monitoring state, which will cause unexpected events; The light transmission performance drops sharply, which affects driving safety. The inside of the precision electrical housing will cause a short circuit due to fog and condensation, which will reduce the reliability of the electrical performance.

Abstract

The invention discloses a product for adjusting and managing internal gas of an electric shell and a manufacturing method thereof. The product comprises an outsourcing layer with an opening, a ventilation layer and a defogging mixture, wherein the ventilation layer is arranged at the opening of the outsourcing layer provided with the opening; the mixture with filtering and defogging functions is arranged in the outsourcing layer provided with the opening. The manufacturing method comprises the following steps: preparing an automatic production line process; charging; injecting the mixture with the filtering and defogging functions into the outsourcing layer; connecting the ventilation layer with the opening of the outsourcing layer provided with the opening in a covering and welding way; drying at a low temperature; vacuuming and sealing an aluminum foil bag. The product is used for adjusting air humidity inside small-sized sealing shell products such as network cameras and automobile lamps, so that the fogging and condensing phenomena of low-water-content damp air inside small-sized sealing shell products such as the network cameras and the automobile lamps on the inner surface of a smooth and transparent shell are avoided, the problem of balance between internal and external pressures is solved, the optical performance of the network cameras and the automobile lamps is brought into play effectively for a long time.

Description

technical field [0001] The invention relates to the technical field of filtration and anti-fogging, in particular to a product for regulating and managing the gas inside an electrical casing and a manufacturing method thereof. Background technique [0002] Products that use microporous airgel materials to control gas changes in tiny spaces are applied to air humidity adjustment inside small and micro-sealed housing products such as automotive ECU control units, precision electronic equipment housings, network cameras, and automotive lights. Balance the air pressure inside and outside, and solve the problem of fogging and condensation caused by the micro-moisture humid air inside the small and miniature sealed shell products such as network cameras and car lights on the inner surface of the smooth and transparent shell, making the network cameras and car lights The optical performance is effectively and permanently brought out, and the complexity of the sealing structure and ...
