Taking the air purification equipment placed in the computer room as an example, the air in the computer room can be dedusted and purified by the air purification device 100 to improve the air quality in the computer room. By arranging the movable base 200 to carry the air purification device 100, the movable base 200 can drive the air purification device 100 to move to different space areas in the computer room, so as to purify the air in different areas in the computer room, so as to speed up the air flow rate in the computer room , to improve the air purification effect in the equipment room.

It should be understood that the air purification device in this embodiment can not only be used to dedust and purify the air in the computer room, but also can be applied to other scenarios that need to purify the air, for example, in residential houses, offices, classrooms, etc. inside the building. Alternatively, the air purification equipment can also be used to purify outdoor air, for example, it can be installed on a construction site for dust removal and purification of the air on the construction site.
