Description

A kind of activated carbon filter screen structure and air purifier

technical field

Background technique

Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building.

There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite, that is, multiple purification technologies and material media are used at the same time.

The filter screen structure of the current cylindrical air purifier is usually a barrel structure. However, for a relatively small air purifier, the volume of the filter screen will be reduced accordingly, which greatly reduces the filtering capacity and effectively removes the air. The purification area is correspondingly reduced, which leads to the technical problem of low purification efficiency.
