Atomizing spray apparatus
First Claim
1. A spray apparatus, comprising:
- a pump;
a reservoir in fluid communication with said pump;
an atomizing unit in fluid communication with said pump and said reservoir;
wherein said atomizing unit comprises a housing having at least a front and a rear wall and defining an enclosed interior space, the front wall having an aperture defined therethrough;
an ultrasonic atomizer disposed within said interior space proximate to said aperture;
a fluid supply port extending through said housing and into said interior space, the fluid supply port being arranged to deliver a fluid pumped by said pump to said ultrasonic atomizer;
an overflow return port extending through said housing and into said interior space, the overflow return port being arranged to return fluid from said interior space to said reservoir;
a weir wall disposed within said interior space defining a fluid receiving space and a fluid overflow space within the interior space of said housing, wherein said fluid supply port is arranged to deliver the fluid into said fluid receiving space and said overflow return port is arranged to return fluid from said overflow space to said reservoir;
wherein said ultrasonic atomizer is arranged within said fluid receiving space.

Abstract
A spray apparatus includes a pump, a reservoir and an atomizing unit in fluid communication within a fluid circuit. The atomizing unit comprises a housing enclosure defining an enclosed interior space. An aperture is defined a front wall of the housing, and an ultrasonic atomizer is disposed within the interior space proximate to the aperture. A fluid supply port extends into the interior space, arranged to deliver a fluid pumped by the pump to the ultrasonic atomizer. An overflow return port extends from the interior space, and is arranged to return fluid from the interior space to the reservoir. The fluid supply port may be arranged to deliver a fluid into a fluid receiving space such that the atomizer becomes at least partially immersed within a fluid during operation. Alternatively, the fluid supply port may be arranged to direct a stream of fluid against a surface of the atomizer.
