Abstract
Disclosed is a nebulization device with a spray orifice plate including an energy transfer element, a spray orifice plate and a driving element. The energy transfer element has at least one first penetrating hole for inputting a liquid from a side and the spray orifice plate is installed on at least one side of the energy transfer element for sealing the first penetrating hole, and the energy transfer element supports the spray orifice plate, and the spray orifice plate has at least one stepped orifice formed at a position corresponding to the first penetrating hole and serves as a transportation channel of the liquid, so that the liquid can be temporarily stored in the stepped orifice and sprayed out through the through hole after vibration and nebulization in order to improve the nebulization effect significantly.
