[0002] Air cleaner is a device for removing impurities in the air. These impurities can be divided into two types of coarse particles and fine particles. Coarse particle impurities, such as larger dust and debris, are often first intercepted by the coarse filter layer of the air cleaner, while fine particle impurities, such as tiny dust and pollen, need to be captured by a more precise fine filter layer. Therefore, the air cleaner is usually equipped with a two-layer structure of coarse filter and fine filter to ensure effective completion of the filtration task. At present, axial cyclone type coarse filter is widely used in the field of air cleaner, especially in the environment with high dust concentration, due to its high filtration performance, it is widely used and called "desert air filter".
