[0044] Working principle of embodiment 2:

[0045] When the water spray turntable 8 is driven to rotate, the water mist flows out from the water outlet and first flows into the spiral groove 14 along the inclined angle between the opening of the water spray outlet and the spiral groove 14, and then sprays into the air along the spiral groove 14, thereby improving the water mist diffusion effect.
