Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric air filtering structure. Background Art

[0002] The non-woven fabrics used for air filtration are usually needle-punched non-woven fabrics. This type of non-woven fabric has the advantages of uniform folding, high strength and good stability. It can purify dust, soot, allergens and harmful gases in the air. The filtering non-woven fabric is made of polyester staple fiber, which can ensure the air intake and air permeability, and can also filter larger flying objects in the air.

[0003] According to the publication number CN213192918U, an air filter with non-woven fabric filtration is disclosed, including a mounting frame, a fixing rod, a non-woven fabric bag and a filter screen. A handle is provided on the top of the base surface of the mounting frame, and the handle is fixed to the mounting frame through a handle fixing seat. A fixing rod is fixedly installed on the inner side of the mounting frame. A fixing hole is opened at the upper left corner of the base surface of the mounting frame. A fastening nut is fixedly installed on the base surface of the mounting frame below the fixing hole, and a screw is fixedly installed on the bottom of the fastening nut. The end of the screw away from the fastening nut passes through the inside of the mounting frame and is fixedly connected to a non-woven fabric frame.

[0004] Although the above patent utilizes a multi-layer filtering process to more efficiently filter impurities in the air and ensure the quality of air filtration, and can easily maintain and replace the core components inside the equipment so that the equipment can be used for a long time, it still has some defects. First, the non-woven bag used by the air filter to filter the air is suspended as a whole, and its side has no support. Its installation is not stable, which makes the non-woven bags easy to stack together, affecting the air filtration effect. For this reason, we provide a non-woven air filter structure to solve this problem. Utility Model Content
