ABSTRACT:
A nozzle plate for use with a spray apparatus and a fabrication method thereof are provided. The nozzle plate has a plurality of orifices each including an inlet end and an outlet end. The inlet end and the outlet end have a geometrical structure with mirror symmetry and a centroid with positional deviation from a pattern center. The pattern center is the center of an imaginary circle circumscribed about the geometrical structure. The geometrical structure controls the propagation direction of liquid spray, expands the nebulizing range per unit density of orifices, enables product miniaturization, and saves energy.
