The inlet pipe 3 includes an inlet end 31 and an outlet end 32. A plurality of circumferentially distributed water jets 321 are provided, and the water outlet 32 extends into the rotating inner cylinder 22. The water inlet pipe 3 is fixed and the rotating inner cylinder 22 rotates at a high speed relative to the water inlet pipe 3, thereby facilitating the transportation of water. Of course, the present application is not limited to this, and the water inlet pipe 3 can also rotate around its own axis.

Specifically, the water inlet end 31 of the water inlet pipe 3 communicates with the water source, and water can be sprayed from the water inlet pipe 3 into the rotating inner cylinder 22 through the plurality of circumferentially distributed water jets 321 at the outlet end 32. Rotate, so that the water sprayed to the rotating inner cylinder 22 spreads into a liquid film on the inner wall of the rotating inner cylinder 22, and under the action of centrifugal force, the liquid film passes through the first mesh hole 221 and is torn under the action of the shear force In the form of a thin water column, water droplets or water mist, in which, by shredding the water into the form of fine water column, water droplets or water mist, the contact area between water and air can be increased, which is conducive to the full mixing of water and air, which in turn is conducive to Purification of dust and other impurity particles in the air by water.

In some embodiments of the present application, there may be a plurality of rotating outer cylinders 23, and the plurality of rotating outer cylinders 23 are spaced apart from the inside to the outside, that is, when there are multiple rotating outer cylinders 23, The rotating outer cylinders 23 are sleeved on the outer side of the rotating inner cylinder 22, and the plurality of rotating outer cylinders 23 have different radial sizes and are sleeved with each other. For example, there may be two rotating outer cylinders 23, and both rotating outer cylinders 23 are sleeved. Outside the rotating inner cylinder 22, the radial dimension of one of the rotating outer cylinders 23 is smaller than the radial dimension of the other rotating outer cylinder 23, and the larger rotating outer cylinder 23 is sleeved on the smaller rotating outer cylinder 23 Externally, in this way, water can pass through the rotating inner cylinder 22 and the plurality of rotating outer cylinders 23 in order to improve the atomizing effect of the atomizing device 2.
