Abstract:
A nebulization structure includes a carrier unit, a vibration unit, a nebulization unit and a position-limiting unit. The carrier unit has a first carrier portion and a first surrounding portion extended from an outer perimeter of the first carrier portion, and the first carrier portion has a through hole. The vibration unit includes an annular vibrating sheet disposed on the carrier unit. The nebulization unit is disposed on the first carrier portion, and the nebulization unit has a plurality of micro holes communicated with the through hole. The position-limiting unit has a first position-limiting portion disposed on the nebulization unit and a second position-limiting portion extended from an outer perimeter of the first position-limiting portion and along the first surrounding portion. The nebulization unit is positioned between the first carrier portion and the position-limiting unit, and the first position-limiting portion has an opening for exposing the micro holes.
