ABSTRACT:
An ultrasonic liquid delivery device including a housing having an internal chamber and at least one exhaust port communicating with the internal chamber. An ultrasonic waveguide in the internal chamber ultrasonically energizes liquid within the chamber prior to the liquid being exhausted through the exhaust port. The waveguide includes a valve member movable relative to the housing between a closed position closing the exhaust port, and an open position. An excitation device is operable in the open position of the valve member to ultrasonically excite the ultrasonic waveguide to atomize liquid exiting the exhaust port.
