The water supply nozzle 2 is located above the rotary disc 31, and water sprayed by the water supply nozzle naturally falls onto the rotary disc 31 under the action of gravity. During the rotation of the rotating disk 31, the water falling on the rotating disk 31 collides with the rotating boss 311, and is broken into finer water droplets and mist. Which facilitates a more uniform diffusion of water onto the turntable 31.

Of course, the rotating disc 31 may be inclined or vertically disposed, as long as it can be ensured that the water sprayed from the water supply nozzle 2 can contact or impact the rotating disc 31, so that the water can be scattered and diffused by the rotating disc 31.

The plurality of protrusions 311 are combined to form a flow guide structure which is radial from the center of the turntable 31 to the outer side of the turntable 31. The water sprayed on the rotating disk 31 is uniformly dispersed on the water absorption filter device 4 by the centrifugal action generated by the rotation of the rotating disk 31 and the flow guiding action of the convex part 311.

The protrusion 311 is in an arc-shaped strip structure. In particular, the arc-shaped strip-like structure has a convex side and a concave side, the convex side being located in front of the concave side in the direction of rotation of the turntable 31. In other words, the concave side is away from the direction of rotation of the turntable 31. Through the boss 311 who sets up the arc structure, can play better water conservancy diversion effect to the water on the carousel 31 to do benefit to the more even diffusion of water to the filter equipment 4 that absorbs water.

Further, the turntable 31 is horizontally arranged, the number of the water supply nozzles 2 is multiple, the water outlets of the water supply nozzles 2 are located above the turntable 31, and the water supply nozzles 2 are uniformly distributed around the rotation axis of the turntable 31.
