[0002] An air filter element is a kind of filter, also known as air filter cartridge, air cleaner, air filter, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms. The traditional air filter element mounting structure performs poorly in terms of sealing performance. During equipment operation, the sealing door is prone to loosening due to vibration or air flow impact. Some traditional air filters only rely on simple buckles or single fixing methods to fix the sealing door. Such structure is prone to loosening during long-term use, which may cause unfiltered air to leak into the filtered air side, reducing the quality of air filtration and affecting the overall performance of the air filtration system. Moreover, the loose sealing may also cause dust, impurities and other substances to enter the filter cartridge, damaging the filter element and shortening the service life of the filter element.
