Therefore, the position of the baffle plate assembly 40 can be changed according to the actual use requirement, so that the air treatment device has a plurality of air treatment operation modes. Like this, can change indoor air quality fast, can also guarantee user experience simultaneously.

In this embodiment, the air duct 11 is formed inside the air duct box 10, and both sides of the air duct box 10 are open structures. Namely, an air inlet and an air outlet of the air duct 11 are formed; alternatively, the cross-sectional shape of the duct 11 is not limited to allow the baffle assembly 40 to move within it and to avoid or partially block the filter module 30. Alternatively, the cross-sectional shape of the air chute 11 may be circular, square, or other shape. Accordingly, the outer shape of the duct box 10 may be a cylinder, a cube, a cuboid, or other cubes.

In this embodiment, the first filtering module 20 is disposed at the air inlet of the air duct 11, the first filtering module 20 filters the air entering the air duct 11, and the filtering structure thereof may be various.
