Description

Technical Field

[0001] The present application belongs to the technical field of air filtering equipment, and specifically relates to an air filtering device that is easy to disassemble. Background Art

[0002] An air filter is a device used to purify the air. It can absorb, decompose or transform pollutants in the air, such as PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc., to improve the cleanliness of the air. An air filter usually includes a housing, a negative pressure generating component, a filter component and a sterilization component. The filter component is used to filter the airflow entering the housing, while the sterilization component is used to further disinfect the filtered air to kill bacteria and viruses attached to the filter component, thereby improving the filtering and purification effect.

[0003] Referring to CN217876315U, an air purification device includes a main shell, a fan device and a functional module. The main shell includes an inner shell and an outer shell surrounding the inner shell. Both the inner shell and the outer shell are hollow shell structures. A receiving space is formed between the inner shell and the outer shell. The fan device is fixedly installed in the inner shell, and the functional module is fixedly installed in the receiving space. Through the arrangement of the inner shell and the outer shell, the functional module can be arranged in the receiving space between the inner shell and the outer shell. The functional module can work independently with the fan device without interfering with each other. Then, the functional module does not need to occupy additional space on the top of the air purification device, thereby solving the technical problems of increased height and excessive volume of the air purification device, which is conducive to miniaturization of the air purification device.
