Problems solved by technology

[0005] Many air purifiers on the market do not have a sealing structure on the end face of the filter screen, because there will be errors in the size of the filter screen during production, small ones will leak air, and large ones will be pressed too tightly; there are also some products in the market. The end face of the filter screen is sealed with a seal, and the purpose of sealing is achieved by the elastic compression of the seal, but the entire end face of the seal is in contact with the end face of the machine, so the entire seal body needs to be compressed to seal well, and it needs The granularity is relatively large, which is not conducive to user experience and disassembly
There are also some products that add a V-shaped protrusion structure on the mating end surface of the filter screen, so that the compressed filter screen seal only uses the amount of compressed V-shaped protrusions to achieve sealing, but such a mechanism has a small compression position. If the size of the net or seal is too small, or the aging and elasticity of the seal become poor, it is easy to cause the hidden danger of air leakage

Abstract

The invention relates to a filter device for an air purifier. The filter device for the air purifier comprises a pressing member, a sealing member, and a screen assembly for pressing the sealing member to an end of the screen assembly; and the end surface of the pressing member that cooperates with the sealing member is provided with a first protrusion having a W-shaped cross section for pressingthe periphery of the sealing member. According to the screen assembly for the air purifier, the first protrusion having the W-shaped cross section is provided at the end surface of the pressing memberand the sealing member, the periphery of the sealing member is pressed, the sealing performance between the pressing member and the sealing member is enhanced, in the case of aging or poor compression of the sealing member, the airflow passes through a W-shaped path from the inside of a screen through the end of the screen assembly, the circulation of the airflow is greatly hindered, and the probability of air leakage from the inside of the screen through the end of the screen assembly is reduced.

Description

technical field [0001] The invention belongs to the technical field of air purification equipment, and in particular relates to a filter screen device for an air purifier. Background technique [0002] Air purifiers are used in home, medical, and industrial fields. In the home field, stand-alone household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air. Since the release of air pollutants in relatively closed spaces is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is internationally recognized as the best way to improve indoor air quality. One of the methods. [0003] With the continuous development of the social and economic level, people's demand for quality of life is increasing, and people are paying more and more attention to their living environment. In recent years, the continuous occurrence of air pollution incidents has greatly promoted the public's ...
