[0002] The structure of traditional air purifiers is a bit heavy and inconvenient to carry. At the same time, the structure is complex and difficult to disassemble and assemble. Especially the air purifier with a centralized air inlet structure. It uses a DC motor to drive the wind wheel to deliver air, and the air is drawn into the purifier structure through the wind blades of the wind wheel to form an air flow that flows out from the air outlet of the purifier after passing through the material box structure. Among them, the material box structure for purifying the air is arranged inside the structure. After using it for a period of time, the filter material in the material box needs to be replaced, but due to the structure of the purifier, the purifier needs to be disassembled as a whole, the used old material box needs to be taken out, and the new material box needs to be put in, and then the installation is restored. The whole operation is cumbersome and takes a long time, which cannot meet the demand for portable use. Therefore, it is necessary to design an air purification device that can solve the above problems. Summary of the invention
