Abstract

The invention belongs to the field of air purification, and particularly relates to an air filtering device. The air filtering device comprises an air channel, a fan and a first air filter detachably installed in the air channel; the first air filter comprises a first air filter frame and a first filter body layer containing a first electrostatic fiber layer; and the fan is arranged in the air channel and located in the downstream positions of all air filters. The air filtering device further comprises a second air filter; the second air filter is connected to an alternating current generating device through a power switch and comprises a second filter frame; the second air filter further comprises a second filter body layer containing a second electrostatic fiber layer; and the length of the second electrostatic fiber layer is two to three times of the length of the first electrostatic fiber layer. By means of the air filtering device, air hyperfiltration can be achieved, filter recycling can be achieved, and the air filtering cost is effectively reduced.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to an air filter device. Background technique [0002] The air filter device includes an air passage, a first air filter installed in the air passage, wherein the first air filter includes a filter frame and a filter body, the filter frame is provided with at least one passage for air circulation, The filter body includes electrostatically chargeable fibers attached to the filter frame such that the filter body achieves a predetermined flow direction from the filter frame to a predetermined flow direction relative to air flowing through the air channel at a certain distance downstream from the filter frame. The extension at the distance position. When air flows through a first air filter of the type described above, the fibers in the filter body move relative to each other, thereby rubbing against each other. The friction created when air flows over the fibers keeps the fibers elec...
