The water washing unit 22 may have any structure capable of performing water washing, and may include, for example, a water pump and a nozzle provided in the water tank 21, and humidifies air taken into the water tank 21 by mist sprayed from the nozzle. For another example, the water washing assembly 22 may be driven to rotate to raise the water in the water tank 21 to form a water curtain, and the water curtain may be used to humidify the air entering the water tank 21.

Thus, when the transmission shaft 221 rotates, the water throwing sleeve 222 is driven to rotate, the water in the water tank 21 is lifted up and thrown out from the water throwing holes under the negative pressure, so as to form a water curtain between the water throwing sleeve 222 and the inner wall of the water tank 21, and when the air current flows through the water curtain, the water curtain washes the air.

The vibration unit 32 may be a vibrating rod, and the vibration unit 32 may be disposed at a position as low as possible in the tank 21 so as not to affect the washing effect of the washing unit on the air and to prevent the water curtain generated by the washing unit 22 from being damaged by the vibration unit 32.

Since the installation position of the vibration part 32 in the water tank 21 is limited, in order to secure the vibration range of the vibration part 32, in a preferred embodiment, as shown in fig. 4, the vibration part 32 includes a vibrator 321 and a cover 322. The vibrator 321 is attached to the ultrasonic transducer 31 to receive ultrasonic vibration generated by the ultrasonic transducer 31. Specifically, the vibrator 321 has opposite first and second surfaces, for example, in the orientation shown in fig. 4, the first surface is a lower surface of the vibrator 321, and the second surface is an upper surface of the vibrator 321.

For example, in the embodiment shown in fig. 5, the second motor shaft 722 is used to drive the drive shaft 221 for rotation. Therefore, the two components can be driven to act simultaneously by using one driving device, so that the structure of the air purifying device is simplified, and the structure of the air purifying device is more compact.
