Meanwhile, the corresponding size of the rotating member 313 can be set based on the overall size limitation of the atomizing head 31 and the size setting of the air flow channel and the water flow channel 315, so as to finally determine the structural size of the mist outlet 317.

The foregoing is only a preferred embodiment of the present invention, which is illustrative, not limiting. Those skilled in the art will appreciate that many variations, modifications, and equivalents may be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
