[0085] Optionally, the air purification device 100 further comprises a detection device for detecting air information in the room; the controller is electrically connected with the detection device, and the controller is used to control the operation of the fan 10, the water throwing device 50 and the driving motor 609 according to the air information in the room.

The first humidity threshold is greater than the third humidity threshold, and the third humidity threshold is greater than the second humidity threshold.

[0091] Optionally, when the air humidity in the room is greater than or equal to the third humidity threshold and less than the first humidity threshold, the controller controls the water throwing motor 501 not to work, controls the fan 10 to work, and controls the second outlet 603 to be completely opened. The airflow flowing into the water tank 20 through the first air duct 605 flows out from the water tank 20, so that the airflow flowing out from the air purification device 100 also has a humidification function, but the humidification amount is smaller, which further improves the humidification effect.
