The top plate is provided with an air outlet close to the side wall, namely the air outlet is communicated with the surrounding high-pressure area. The external environment of the air outlet is a normal pressure environment, so that pressure difference exists at the air outlet. The air in the fan case 300 flows from the high-pressure region of the fan case 300 to the outside of the fan case 300 by the pressure difference. The air inlet of fan case 300 is seted up in the bottom plate, and is located the middle part, and the air inlet is located the low-pressure zone. The air in the water tank 200 is in a normal pressure environment, and the air inlet of the fan box 300 has pressure difference. Driven by the pressure difference, the air in the water tank 200 enters the fan box 300 through the water curtain generated by the water curtain generating unit 210. Thus, air continuously enters the fan box 300 from the air inlet at the bottom of the fan box 300 and leaves the fan box 300 from the air outlet of the fan box 300, and the air is driven to flow in the water curtain air purifier. By adopting the arrangement form, water drops in the air entering the fan box 300 can be separated, so that the cleanness of the environment affected by the moisture content of the outlet air of the water curtain air purifier is avoided.

The air duct 330 is a cylindrical structure and is vertically arranged. The diameter of the air guide duct 330 is gradually reduced from bottom to top. The opening at the bottom of the air guide 330 is used to introduce the air in the water tank 200 into the fan case 300. The top opening of the air duct 330 is an air inlet of the fan box 300 and/or an air outlet of the water tank 200. The inner wall surface of the air duct 330 plays a role in guiding air in the water tank 200 into the fan case 300.

The upward extension of the air duct 330 is inserted into the air inducing ring 314, and the air inducing ring 314 and the air duct 330 partially overlap in the vertical direction. This provides a check for air in the fan case 300. Specifically, when the fan is rotated, air in the fan box 300 moves from the fan to the periphery of the fan box 300. There is a pressure differential between the central low pressure region and the surrounding high pressure region, and some air may return from the surrounding high pressure region to the central low pressure region. The air guide tube 330 extends upward and is inserted into the wind-guiding ring 314, and performs a stop for the horizontal movement of air, thereby being capable of playing a role of stopping the movement to some extent. In addition, even if air still enters the plurality of blades 313 of the fan from the gap between the air guide ring and the air guide ring 314, the moving direction of the air is upward movement, and the air in the air guide cylinder 330 can be guided upward under the injection effect of the air.
