It is understood that a plurality refers to two, three or more.

Any two adjacent baffle walls 110c are spaced and at least partially staggered, so that on one hand, the influence of the baffle walls 110c on the flow of aerosol can be reduced, and the aerosol can smoothly flow out towards the air outlet channel 10b, and on the other hand, the effective absorption of large-particle liquid drops ejected by the ultrasonic atomization sheet 121 is also facilitated.
