Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning filtration, in particular to an automobile air-conditioning filter. Background Art

[0002] The car air conditioning filter can absorb tiny particles (such as dust, powder, etc.) that are invisible to the naked eye and float in from the outside of the car, and remove unpleasant odors and gas odors. Once these tiny particles enter the interior of the vehicle, they may not only cause allergies to the car passengers, but they may also mold and multiply bacteria in the air conditioning system (HVAC system), causing the car to emit odor when the air conditioning system is started for heating or cooling.

[0003] However, when replacing the filter element of some existing automobile air-conditioning filters, most of them remove the cover plate protecting the filter element on one side of the filter, then take the filter element out of the filter, install the new filter element into the filter, and complete the filter element replacement inside the filter. Due to the small space in the car, the filter element replacement is time-consuming and labor-intensive, resulting in low filter element replacement efficiency. Secondly, when the filter element of the filter has not been replaced for a long time, some dust and impurities fall into the bottom of the filter through the filter element, causing damage to the electrical components installed in the bottom of the filter. Moreover, when the filter element is taken out to replace it, the dust and impurities attached to the surface of the filter element are also easy to fall into the bottom of the filter, which is inconvenient to clean.
