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 of the air filtering device. The air filtering device comprises a framework, a filtering net, a first driving component, a second driving component, a first transmission component and a second transmission component, wherein the filtering net, the first driving component, the second driving component, the first transmission component and the second transmission component are arranged on the framework; the filtering net comprises a plurality of transverse silk threads and a plurality of vertical silk threads; the first driving component is connected with the transverse silk threads through the first transmission component; the second driving component is connected with the vertical silk threads through the second transmission component; the first driving component can drive the first transmission component to drive the transverse silk threads to move, so that the distance among the plurality of transverse silk threads is regulated; the second driving component can drive the second transmission component to drive the vertical silk threads to move, so that the distance among the plurality of vertical silk threads 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 (such as PM2.5 or PM0.3) in air.

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...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the filter gap of the filter screen in the existing air filter device cannot be adjusted, the air filter device may not be able to filter the excessive pollutants in the air, or may affect the air filter. To solve the problem of the filtration rate of the device for excessive pollutants in the air, the present invention provides an air filter device, which includes a frame, a filter screen arranged on the frame, a first drive member, and a second drive member , a first transmission member and a second transmission member, the filter screen includes a plurality of horizontal wires and a plurality of vertical wires, the first drive member is connected with the horizontal wires through the first transmission member, the first Two drive members are connected to the vertical wires through the second transmission member, and the first drive member can drive the first transmission member to drive the horizontal wires to move and thus adjust the distance between the multiple horizontal wires. distance, the second drive member can drive the second transmission member to drive the vertical wires to move and thus adjust the distance between the plurality of vertical wires
