Abstract
A volatile material dispenser may include a housing adapted to hold a refill containing a volatile material and a nebulizer in communication with the refill and the volatile material within the refill, wherein the nebulizer is adapted to volatilize and emit the volatile material as nebulized particles. The nebulizer may include a piezoelectric element having a central aperture and first and second opposing surfaces and an orifice plate disposed adjacent the first surface of the piezoelectric element.
Claims19
A nebulizer assembly comprising:
- a piezoelectric element having a central aperture and first and second opposing surfaces;
- an orifice plate disposed adjacent the first surface and extending into the central aperture and beyond the second surface of the piezoelectric element;
- and
- a stainless steel plate disposed adjacent the orifice plate opposite the piezoelectric element,
- wherein the stainless steel plate includes a cylindrical portion extending through the central aperture.
A volatile material dispenser, comprising:
- a housing adapted to hold a refill containing a volatile material;
- and
- a nebulizer in communication with the refill and the volatile material within the refill, wherein the nebulizer is adapted to volatilize and emit the volatile material as nebulized particles and the nebulizer comprises:
- a piezoelectric element having a central aperture and first and second opposing surfaces;
- an orifice plate disposed adjacent the first surface and extending into the central aperture and beyond the second surface of the piezoelectric element;
- and
- a plate disposed adjacent the orifice plate opposite the piezoelectric element and extending through the central aperture.
