Problems solved by technology

However, air pollutants come from a wide range of sources. A single air purifier is limited by its functions and materials, and each has its own shortcomings. For example, HEPA has a strong adsorption effect, but it cannot effectively decompose harmful substances in the air. The existing market is in urgent need of a collection. An air purification device with multiple functions, effective filtration and purification, disinfection and sterilization, and deodorization

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] see figure 1 , for the convenience of description, we set the direction of the rear cover 10 of the air purifier shown in the figure pointing to the front panel 1 as the front, and the inside of the body as the inside. The air purification filter provided by the present invention includes several layers of filter screen layers, and the filter screen layer includes a HEPA filter screen 6, an antistatic filter screen 7, a light-cool catalyst filter screen 9, and the light-cool catalyst filter screen 9 includes a cold catalyst layer attached to the filter screen through soaking and drying, and a photocatalyst layer attached to one side of the filter screen through spray drying.

[0021] More preferably, also comprise an activated carbon filter screen 8, it is arranged between antistatic filter screen 7 and light-cold catalyst filter screen 9, therefore, from front...

Abstract

The invention discloses an air purification filter which comprises a plurality of air filter screen layers. Each filter screen layer comprises an HEPA (high efficiency particulate air) filter screen, an anti-static filter screen and a light-cold catalyst filter screen, each light-cold catalyst filter screen comprises a cold catalyst layer and a light catalyst layer, each cold catalyst layer is dried in a soaking manner and attached onto the corresponding filter screen, and each light catalyst layer is dried in a spraying manner and attached onto the surface of one side of the corresponding filter screen. Each filter screen layer has different functions, so that an air refresher of the air purification filter has various functions such as air filtration, purification, sterilization, deodorization and electrostatic elimination.

Description

technical field [0001] The invention relates to the technical field of air purification, and more specifically relates to an air purification filter and an air freshener thereof. Background technique [0002] With the continuous progress of society and the advancement of urbanization, people's living standards continue to improve, but the problem of environmental pollution is also becoming more and more serious. After the occurrence of "smog" in many large cities in China, the problem of air quality has been highly valued. Air purifiers that can effectively improve indoor air quality are popular. At present, there are a variety of air purifiers on the market for air pollution and purification requirements, such as activated carbon air purifiers, photocatalyst air purifiers, high-efficiency air particulate filter (HEPA) air purifiers, negative ion generators, etc. air purifier. However, air pollutants come from a wide range of sources. A single air purifier is limited by it...
