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.
Claims15
A nozzle plate of a spray apparatus, comprising:
- a main body with a plurality of orifices each comprising an inlet end and an outlet end, wherein at least one of the inlet end or the outlet end has a geometrical structure with mirror symmetry and a centroid with positional deviation from a pattern center, the centroid being a barycenter (center of mass) of the geometrical structure, and the pattern center being a center of an imaginary circle circumscribed about the geometrical structure.
A nozzle plate of a spray apparatus, comprising:
- a main body with a plurality of grooves and a plurality of orifices each comprising an inlet end and an outlet end, wherein at least one of the inlet end or the outlet end has a geometrical structure with mirror symmetry and a centroid with positional deviation from a pattern center, the centroid being a barycenter (center of mass) of the geometrical structure, and the pattern center being a center of an imaginary circle circumscribed about the geometrical structure.
