[0002] The air purification filter is a core component in an air purifier, mainly used to filter particulate matter, odors, and harmful substances in the air to ensure the cleanliness and health of indoor air. After long-term use of the air purification filter, various solid pollutants or air pollutants will stay in the internal filter layer of the air purification filter, affecting the purification effect.

[0003] The existing air purification filter designs generally adopt a fixed structure, which not only limits the convenient disassembly of its internal filter layer, but also the filter layer is often made into an integrated large component, lacking flexibility in splitting, bringing inconvenience to the cleaning and maintenance of users. In addition, when more impurities accumulate in the internal filter layer of the filter, due to the difficulty of immediate detection, it directly affects the performance of the air purification filter. Therefore, this design has obvious deficiencies in terms of practicality and efficiency. Summary of the Invention

At the same time, the rubber column can exert a reverse force on the pressure sensor, allowing the magnitude of the force applied to the filter element to be indirectly reflected by the pressure value of the pressure sensor. This ensures that the pressure on the filter element is appropriate, enabling multiple filter elements to fit tightly together and preventing damage to the filter element due to excessive pressure. It helps prevent air containing pollutants from passing through the gap between two filter elements, ensuring the purification effect of the filter element and laying the foundation for a split-type filter element.

[0016] 3. In the present invention, by providing a reciprocating lead screw, a sliding seat, and a connecting block, the sliding seat can drive the wind speed sensor to move up and down reciprocally, enabling the wind speed sensor to comprehensively detect the flow rate of air passing through the filter element. When the air flow rate is lower than the specified value, it indicates that there is too much accumulation of impurities inside the filter element and it needs to be cleaned. This helps to promptly detect a large accumulation of impurities inside the filter element and ensures the effectiveness of the air purification filter element. BRIEF DESCRIPTION OF THE DRAWINGS
