In some embodiments, a plurality of the cocurrent flow channels 4 are distributed in a clockwise direction. Through the design, the formation of the rotational flow is facilitated, and the clockwise flow channel 4 is distributed in the clockwise direction, so that the integral rotary atomization effect is good.
