Abstract

The invention discloses a formaldehyde filter screen and an air treatment device. The formaldehyde filter screen comprises a base plate, the base plate is provided with a plurality of vent holes extending in the thickness direction of the base plate, each vent hole comprises a reduction section, and the cross section area of each reduction section is gradually increased or decreased in the thickness direction of the base plate. Thus, the hole wall area of the vent holes can be increased, the filtering area of the formaldehyde filter screen can be effectively increased, the filtering effect ofthe formaldehyde filter screen can be effectively improved, and the purifying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde filter screen and an air treatment device. Background technique [0002] In the related art, the ventilation holes of the formaldehyde filter are usually set as straight holes, which cannot effectively improve the filtering effect of the formaldehyde filter. Contents of the invention [0003] The main purpose of the present invention is to propose a formaldehyde filter, aiming to solve the technical problem in the prior art that the filtering effect of the formaldehyde filter cannot be effectively improved. [0004] In order to achieve the above object, the present invention proposes a formaldehyde filter, the formaldehyde filter includes a substrate, the substrate has a plurality of ventilation holes extending along the thickness direction of the substrate, the ventilation holes include a shrinkage section, the The cross-sectional area of ​​the reduced...
