Filter layer, air filter structure and purifier

Abstract

The invention relates to the technical field of air purification, particularly to a filtering layer, an air filtering structure and a purifier. The filtering layer comprises a filtering layer body, which is bent and folded into a wave shape, wherein the wave folding included angle [theta] is equal to arctan[(4*b*L) / (4*L<2>-b<2>)], b is a wave folding interval, and L is a wave folding depth. According to the invention, the filtering layer body is folded according to certain folding distance and folding depth requirements to form a wave-shaped structure, the wave folding included angle of the filtering layer body is set to be [theta]=arctan[(4*b*L) / (4*L<2>-b<2>)], b is a wave folding interval, L is a wave folding depth, the formaldehyde filtering efficiency of the wave-shaped filtering layerbody formed by the parameters can reach 80-90%, and the filtering efficiency of PM2.5 / PM10 and other air particle pollutants is also kept at about 90%; after bending and folding, the folding stiffness can be self-maintained, and the folds do not need to be bonded and fastened by using melt glue, so that a potential peculiar smell pollution source is eliminated, the filtering area is increased, the uniform penetration of the folds of the filtering layer is completely realized, and a user can conveniently suck dust and clean the filtering layer.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a filter layer, an air filter structure and a purifier. Background technique [0002] With the rapid development of the electronic industry and the pharmaceutical industry, the role played by air cleaning technology is becoming more and more important. Among many air purification technologies, air purifiers are the most widely used, mature, and undisputed. However, the resistance of filter structures in air purifiers is generally not optimized at present, resulting in high resistance during use, high energy consumption, and poor filtration efficiency. The effect is poor, and the filter structure needs to be bonded and fixed with hot melt adhesive to ensure the stability of the structure, and the use of the colloid is prone to odor. At the same time, the aldehyde removal technology on the existing air purifier is generally to install an activated carbon filter layer behi...
