[0002] In order to protect the health of family members and improve the quality of life, especially in cases of severe environmental pollution or special health needs, the role of air purification filters is particularly important. Air purification filters are devices used to improve air quality. They can remove pollutants in the air, such as dust, pollen, bacteria, viruses and other harmful particles.

[0003] In existing air purification filters, air enters the device and blows to the filter screen at the same position, which will cause the filter material in that area to be oversaturated, while the filter material in other areas cannot fully function, resulting in a waste of resources. In addition, since some filters have not been fully used for a long time, the overall purification efficiency will be reduced;

[0004] Existing air purification filters generally have a fixed working range when in use. The range of purification and filtration is small, the purification time is long, and the filter element inside needs to be replaced after a period of use. When replacing, the entire device needs to be opened for replacement, which is not convenient for quick disassembly and assembly of the filter element. Utility Model Content

[0005] The main purpose of the utility model is to provide an air purification filter, which solves the problem that the air enters the device and blows to the filter without changing its position through the provided conveying mechanism, and solves the problem that the whole device needs to be opened for replacement, which makes it inconvenient to quickly disassemble and assemble the filter element, through the provided filtering mechanism.
