Eleven first atomizing blades 305, middle connecting plates 306 and second atomizing blades 307 are evenly spaced and distributed on the surface of the connecting ring frame 304. The arrangement of multiple groups of first atomizing blades 305, middle connecting plates 306 and second atomizing blades 307 can increase the extension direction of atomization, better expand the atomization range, and have a good dust reduction effect. One end of the middle connecting plate 306 away from the side of the first atomizing blade 305 is connected to the side of the second atomizing blade 307 close to the first atomizing blade 305.
