For example, an automobile filter element, as a structural part for filtering impurities, is usually applied in regions such as an engine, an internal combustion engine or an air conditioning system. However, a conventional automobile filter element is usually fixedly installed inside an automobile body, and it is difficult to replace it after being contaminated. Moreover, once the air conditioner filter element is replaced, the entire filter chip must be removed, resulting in the problem of product waste.

[0003] As described in the publicly disclosed patent "A new energy vehicle air conditioning system convenient for filter element replacement" with the publication number CN108725131B, the air conditioning system, as an important part of a new energy vehicle, greatly improves the comfort of people driving a new energy vehicle. When the filter element inside the air conditioning system has worked for a long time, people need to replace the filter element. Nowadays, when people replace the filter element, they need to disassemble multiple components, which greatly prolongs the time for replacing the filter element of the air conditioning system, thus greatly reducing the efficiency of filter element replacement. Moreover, after a general filter element has been used for a long time, a large amount of dust will accumulate on the filter element, resulting in the problem that when people disassemble the filter element, the dust on the filter element is easily shaken into the vehicle, thereby reducing the practicality of the air conditioning system.
