Description

Technical Field

[0001] The utility model relates to the technical field of air filter cotton, in particular to an air filter cotton. Background Art

[0002] Air filter cotton, also known as air cotton, is the full name of air filter cotton, which is mainly used to filter dust particles in the air. According to different materials and production processes, it can be divided into many types, including non-woven filter cotton, synthetic fiber filter cotton, glass fiber filter cotton and activated carbon filter cotton, etc. It is often used in the inlet of ventilation equipment and air control systems, as well as filter materials for filter materials such as plate filters. Medium-efficiency filter cotton mainly filters dust particles larger than 1μm, and is usually used for secondary or ultimate filtration after coarse-efficiency filtration. High-efficiency filter cotton is mainly used in environments such as hospitals or laboratories that require high filtration requirements. In addition, air filter cotton also has good hygroscopicity and heat preservation, which makes it widely used in fields such as sportswear. The air filter cotton used in the air-conditioning field needs to be replaced after a period of use.

[0003] For example, the Chinese patent "An Air Filter Cotton" with announcement number CN219405688U includes a needle-punched cloth layer, a melt-blown cloth layer and a carbon-clad cloth layer arranged in sequence from top to bottom. A first degradable filter layer is provided at the bottom of the carbon-clad cloth layer, and a second degradable filter layer is provided on the top of the needle-punched cloth layer. The thickness of the first degradable filter layer or the second degradable filter layer is greater than the total thickness of the needle-punched cloth layer, the melt-blown cloth layer and the carbon-clad cloth layer. The first degradable filter layer and the second degradable filter layer are both made of polylactic acid fiber material, and a nanofiber filter cloth is also provided between the needle-punched cloth layer and the melt-blown cloth layer. A tensile mesh is provided in the carbon-clad cloth layer, and the tensile mesh is made of glass fiber material. The thickness of the first degradable filter layer and the second degradable filter layer is the same, and the thickness of the first degradable filter layer or the second degradable filter layer is 5-10 cm.

[0004] Although the above-mentioned prior art can realize the filtering of air by filter cotton, in actual use, on the one hand, the air filter cotton is difficult to replace the cotton body. When the air filter cotton is replaced after being used for a period of time, the entire air filter cotton needs to be removed, which makes the steps of removing the air filter cotton cumbersome, thereby reducing the efficiency of replacing the air filter cotton. On the other hand, the intercepted floating dust is easily attached to the surface of the air filter cotton due to static electricity. When the air filter cotton is filtering, the intercepted floating dust generates static electricity by friction with the surface of the air filter cotton, causing the floating dust to adhere to the surface of the air filter cotton and reduce the filtering efficiency of the air filter cotton. Therefore, it does not meet the existing needs. In this regard, we propose an air filter cotton. Utility Model Content
