Abstract: A liquid nebulizing assembly includes an actuating ring plate, a solid nozzle plate and a piezoelectric element. A plurality of nozzle holes is formed and distributed all over the solid nozzle plate and included between the actuating ring plate and the piezoelectric element. The solid nozzle plate includes at least one reinforcing portion in a 3D shape, and continuously and uninterruptably protruded to form at least one ring-shaped solid with respect to the center of the solid nozzle plate. The assembly is applicable to a relatively ductile and thin material to reduce the power consumption for the vibration transmission and achieve power saving.
