A kind of cold catalyst filter screen for air purifier

Abstract

A cold contact agent filter screen for an air purifier is characterized by comprising a frame and a filter screen body; a connecting strap is arranged on the upper portion of the inner edge of the frame, the filter screen body is composed of a plurality of triangular filtering holes, a plurality of retention plates are transversely and evenly arranged in the filtering holes, the two sides of the retention plates are fixedly connected with the inner walls of the filtering holes, the other sides of the retention plates are separated from the inner walls of the filtering holes so that a gas channel can be formed, and an S-shaped gas channel is formed as a whole. The retention plates are cold contact agent filtering layers. A sealing strip is arranged between the filter screen body and the frame. The cold contact agent filter screen has the advantages that the filtering holes which are arranged orderly effectively support the rigidity of the whole filtering screen, the retention plates are transversely and evenly arranged in the filtering holes, the two sides of the retention plates are fixedly connected with the inner walls of the filtering holes, the other sides of the retention plates are separated from the inner walls of the filtering holes, the S-shaped gas channel is formed as a whole, the gas path is effectively prolonged, the contact time of gas and cold contact agents is prolonged, and the purifying effect is improved.

Description

technical field [0001] The invention relates to the field of filter screen accessories for air purifiers, in particular to a cold catalyst filter screen for air purifiers. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various pollutants in the air and effectively improve the cleanliness of indoor air. It is used in home, medical and industrial fields. In the field of home, single-unit household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of volatile organic compounds in indoors, underground spaces, and cars caused by decoration or other reasons. Due to the persistent and uncertain characteristics of the release of air pollutants in relatively closed spaces, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air...

Problems solved by technology

Most of the manufacturers on the market use photocatalysts. Photocatalysts can only work when the light source medium reaches 380nm. The general publicity that ultraviolet radiation can play a catalytic role is a way to mislead consumers. Ultraviolet light is currently used the most. It is 254nm or 365nm, even the maximum value cannot meet the catalytic effect of photocatalyst
