Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

The present invention mainly relates to: an air filtering device comprises a frame body 1, a first roller shaft 2 and a second roller shaft 3 which are fixed at two opposite ends of the frame body 1 at intervals, a plurality of supporting shafts 4 arranged between the first roller shaft 2 and the second roller shaft 3 at intervals, and a filtering medium 5. The filter medium 5 is provided on the first roller shaft 2, and one end of the filter medium 5 is wound around the second roller shaft 3 via a plurality of support shafts 4 in sequence.

Referring to fig. 1, in this embodiment, a plurality of circular holes 6 are disposed inside two sides of the frame 1, and the plurality of support shafts 4 are fixedly connected to the frame 1 through the circular holes 6 for supporting the filter medium 5.

Furthermore, the plurality of support shafts 4 are rotatably fixed on the frame 1, so that the support shafts can be conveniently installed in the frame.

As shown in fig. 2, in the present embodiment, two adjacent support shafts 4 of the plurality of support shafts 4 are arranged in a staggered manner along the arrangement direction of the first roller shaft 2 and the second roller shaft 3 and the second direction perpendicular to the arrangement direction, so that the contact area between the filter medium 5 and the air can be increased, and the dust removal efficiency can be improved.

Preferably, the lateral distances between the adjacent support shafts 4 along the plane direction of the first roller shaft 2 and the second roller shaft 3 are equal, and are parallel to each other in the space of the frame 1, that is, the support shafts 4 are uniformly arranged in the frame 1, and the distances between the adjacent support shafts are the same.
