Description

Technical Field

[0001] The utility model relates to the technical field of filter element structures, and more specifically, to an air-conditioning filter element structure. Background Art

[0002] Filters are often used in household air conditioners and car air conditioners. When a car is driving with the air conditioner on, it needs to inhale outside air into the car. However, the air contains many different particles, such as dust, pollen, soot, abrasive particles, ozone, odor, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. If there is no air conditioning filter to filter these particles, once they enter the car, not only will the car air conditioner be polluted and the cooling system performance be reduced, but also the human body will have allergic reactions after inhaling dust and harmful gases, damage the lungs, and be irritable due to ozone stimulation. In addition, there is also the influence of odor, which affects driving safety.

[0003] For example, a vehicle air conditioning filter structure with publication number CN214182316U has all filter layers bonded together. After long-term use, a large amount of dust and dirt accumulates, causing the filter to be blocked, thereby affecting the uniform filtration of the air and reducing the overall filtration efficiency. In addition, the filter layers are bonded together, and each layer cannot be effectively cleaned separately when cleaning the filter, which may result in poor cleaning effect or dust residue, affecting the reuse effect of the filter.
