Abstract
An ultrasonic liquid atomizer of the type having an piezoelectric vibrating system with the vibrations from an piezoelectric transducer being transmitted to an atomizer plate through conical members wherein the atomizer plate is positioned interiorly of a chamber defining member adjacent a discharged orifice and blower means are positioned to induce an air flow through the chamber defining member past the atomizer plate to the orifice providing a jet-like flow past the atomizer plate periphery.
Claims11
An ultrasonic liquid atomizer utilizing a piezoelectric vibratory system with the vibrations of an piezoelectric transducer transmitted to a liquid atomizer plate by a conical transformer comprising:
- a housing defining an air flow chamber having an outlet therefrom, an atomizer plate positioned in said housing means adjacent the outlet defining an air flow jet area around the atomizer plate and through the outlet and blower means inducing an air flow through the housing past the atomizer plate and thence through the outlet.
A liquid atomizer comprising:
- an outer housing, and an inner housing, a piezoelectric vibratory system including a piezoelectric transducer attached to an atomizer plate through an intermediately positioned conical transformer, the transformer having a mounting ring intermediate the transducer and the atomizer plate, the mounting ring positioned approximately at a vibratory node area of the conical transformer, the mounting ring forming an end cap for the inner housing, the inner housing mounted in the outer housing through support means extending between the inner and outer housing with the atomizer plate positioned adjacent a discharge orifice of the outer housing, a peripheral gap between a periphery of the atomizer plate and an inner periphery of the discharge orifice, blower means interior of said outer housing providing an air flow through said outer housing past said atomizer plate periphery and through said discharge orifice, and liquid conduit means providing a flow of liquid to be atomized to an exterior surface of the atomizer plate.
A liquid atomizer comprising:
- an outer housing having interior walls, portions of which converge to a discharge orifice from said housing, a piezoelectric vibratory system within said housing, said piezoelectric vibratory system including a transducer attached to an atomizer plate through an intermediately positioned transformer, the atomizer plate positioned adjacent the discharge orifice interiorly of the housing and having peripheral portions of the atomizer plate spaced from the periphery of the discharge orifice defining an air flow space between the periphery of the atomizer plate and the periphery of the orifice, and blower means associated with the housing inducing an air flow past the periphery of the atomizer plate, through the air flow space and out of said discharge orifice.
