Abstract

The invention provides an air filtering device, which is characterized by comprising filter paper and a sealing cover, wherein the filter paper is in the form of an open cavity; one end of the filter paper is provided with an air inlet; and the other end of the filter paper is sealed through the sealing cover. In the technical scheme, air is blocked by the sealing cover after entering the open cavity of the filter paper when the air filtering device provided by the invention is arranged on air filtering equipment for use, so that the impact force of air is reduced, and the situation of entrance of impurities into the filter paper under the action of high-speed extrusion in the prior art is avoided; and meanwhile, the side wall area of the through cavity is larger than the area of flat plate filter paper in the prior art, so that the air filtering effect is enhanced remarkably, and the filtering speed is increased greatly.

Description

technical field [0001] The invention belongs to the field of air filtering equipment, and in particular relates to an air filtering device. Background technique [0002] With the increasingly serious air pollution, the air purification device has become more and more important to life, medical treatment, production, etc. At present, the more popular air purification equipment on the market uses flat filter paper, which needs to filter the air through the filter. The interception of the paper plays the role of separating impurities such as dust and bacteria from the pure air. However, at present, the air duct is widely used to directly supply air to the flat filter paper. The wind speed is relatively high, and the direct pressure on the flat filter paper is too high. When the dust hits the filter paper at high speed, it is easy to be squeezed through the filter paper, thereby reducing the quality of the air after filtration. In addition, the flat plate has a small air passing...
