Ultrathin air filtering screen

Abstract

The invention relates to an ultrathin air filtering screen. The whole thickness of the ultrathin air filtering screen is 3 to 9 mm. The ultrathin air filtering screen structurally comprises a filtering cotton layer, a metal net layer and a paper framework, wherein the metal net layer is arranged on the top surface and the bottom surface of the filtering cotton layer, and the four edges of the filtering cotton layer and the metal net layer are connected and fixed by the paper framework. The ultrathin air filtering screen disclosed by the invention has the advantages that the three-layer structure is simple and effective; the middle filtering cotton layer is reinforced by the metal net layer, then, the peripheric frame is fixed by the paper framework, so that the thickness of the primary andmedium effect filtering screens is effectively reduced to 3 to 9 mm, and the thickness is greatly reduced; the filtering cotton layer preferably uses G3 to F8 filtering level filtering cotton, so that the filtering effect is ensured; and as the volumes of the primary and medium effect filtering screens are reduced, the dust holding capacity of the filtering equipment is effectively increased, andthe filtering effect is improved.

Description

technical field [0001] The invention relates to an ultra-thin air filter. Background technique [0002] With the continuous development of the field of air purification, air purification equipment is becoming more and more advanced. The volume of air purification equipment is one of the important indicators that determine its purification effect. And the area of ​​the high filter determines the dust holding capacity of the filter equipment. [0003] In the prior art, the volume of the primary and secondary filter screens is large, and the area of ​​the high-efficiency filter screen is insufficient, which all lead to insufficient dust holding capacity of the air purification equipment and affect the air purification effect. Contents of the invention [0004] The present invention proposes an ultra-thin air filter, which aims to overcome the above-mentioned deficiencies in the prior art, realize effective shrinkage of the volume of primary and medium-efficiency filters, and...
