Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a composite filter structure for a vehicle air purifier. Background Technology

[0002] A composite filter for a car air purifier is a filter that combines multiple filter materials. It is designed to combine more filter materials together to remove particulate matter and harmful gases from the air at the same time, and to deal with a variety of air pollutants, providing a more comprehensive air purification effect.

[0003] Existing patent document CN222092792U discloses an air purifier filter structure, including a filter body. The filter body includes a longitudinally stacked filtration unit and a liquid distribution unit. The bottom of the liquid distribution unit is lower than the bottom of the filtration unit. A hopper is provided on the front side of the filtration unit and the liquid distribution unit. A discharge mechanism is provided at the bottom of the hopper to discharge particulate matter from the hopper. By designing a hopper in the composite filter, particulate matter for preparing disinfectant solutions can be pre-stored in the hopper. This facilitates the automatic preparation of disinfectant solutions in the all-in-one air purifier and allows for on-demand discharge via the discharge mechanism. This makes it easier to control the concentration of the prepared disinfectant solution. Furthermore, the combined structure of the filtration unit and the liquid distribution unit ensures that the basic filtration function of the filter is not affected, and the disinfectant solution in the liquid preparation tank can be drawn above the liquid surface to allow for gas-liquid contact with the airflow.

[0004] Although the device has many beneficial effects, it still has the following problems: the filtration mechanism of the device is relatively weak, and its effect in purifying the air needs to be improved. Secondly, the replacement of the filter media is relatively cumbersome, which is difficult for the staff. Utility Model Content
