Description

Technical Field

[0001] The utility model relates to the technical field of welding smoke treatment, in particular to a formaldehyde removal low wind loss filter. Background Art

[0002] The air conditioner is a common household appliance that exchanges air inside and outside when cooling or heating. The air is filtered through its built-in filter to intercept tiny particles such as dust, pollen, bacteria, viruses, pet hair, etc., preventing these pollutants from entering the indoor air. In order to improve the filtering and adsorption effect of the filter, a formaldehyde-removing low-wind-loss filter is needed.

[0003] After searching, the Chinese patent announcement number is: CN207769379U, which discloses a membrane-coated activated carbon filter element, including an activated carbon filter element and a protective film. The activated carbon filter element is provided with protective films at both ends, and the activated carbon filter element and the protective film are connected by adhesive bonding. The membrane-coated activated carbon filter element is formed by covering the upper and lower sides of the activated carbon filter element with a protective film with adhesive. The size of the protective film can be customized according to the size of the activated carbon filter element. The protective film with adhesive can be easily adhered to the surface of the activated carbon filter and can be easily uncovered when used, thereby solving the problem of the activated carbon filter element being stuck during transportation. The problem of activated carbon powder falling off due to transportation collision and friction is solved. The fallen powder is directly stuck by the protective film covering the surface, and the powder will not fall into the packaging bag, preventing contamination of the product frame and packaging bag. At the same time, the problem of oxidation of the adsorption material filled in the activated carbon filter element due to contact with the air is solved, which extends the shelf life of the activated carbon filter element and provides great help to people. However, in actual use, the device cannot assemble the filter well and quickly install it and the air conditioner. In actual use, the replacement and disassembly and cleaning steps are relatively cumbersome, which reduces the convenience of the device. Utility Model Content
