Air filtering device and control method for air filtering device

Abstract

The invention belongs to the technical field of air purification, and particularly relates to an air filtering device and a control method for the air filtering device. The air filtering device comprises a framework, a filtering net assembly, a driving component and a transmission component, wherein the filtering net assembly, the driving component and the transmission component are arranged on the framework; the filtering net assembly comprises at least two layers of filtering nets; the driving component is connected with a filtering net through the transmission component; the driving component can drive the transmission component to drive the filtering net to move, so that the filtering gap of the filtering net assembly is regulated. Through such arrangement, the air filtering device can regulate the filtering gap of the filtering net assembly according to the particle size of standard exceeding pollutants in air, for example, if the standard exceeding pollutants in the air are PM2.5, the filtering gap of the filtering net assembly is regulated to conform the size for filtering the PM2.5; if the standard exceeding pollutants in the air are PM 0.3, the filtering gap of the filtering net assembly is regulated to conform to the size for filtering the PM 0.3; the effective filtering on the pollutants can be ensured; the filtering rate on the pollutants can be improved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and specifically provides an air filter device and a control method for the air filter device. Background technique [0002] At present, air pollution and the deterioration of the atmospheric environment are becoming more and more serious, and have developed into an important factor affecting people's health. [0003] In order to avoid or reduce the impact of air pollution on people's health, air filter devices have become a necessity in people's lives. Air filter devices are generally equipped with filter screens to filter particulate pollutants in the air, such as dust, PM2.5 or PM0.3, etc., the particle size of these pollutants is different, however, the filter gap of the filter screen in the existing air filter device is fixed, so when the particle size of the excessive pollutants in the air is less than When the filter gap of the filter screen is too large, the filter screen will n...
