ABSTRACT:
An ultrasonic liquid delivery device has an elongate housing with an internal chamber, an inlet in fluid communication with the internal chamber of the housing, and an outlet in fluid communication with the internal chamber of the housing. An elongate ultrasonic waveguide is disposed at least in part within the internal chamber of the housing to ultrasonically energize liquid within the internal chamber prior to the liquid being exhausted from the housing through the outlet. The ultrasonic waveguide has an agitating member extending outward from the ultrasonic waveguide within the internal chamber of the housing intermediate the inlet and the outlet. The agitating member and the ultrasonic waveguide are constructed and arranged for dynamic motion of the agitating member relative to the ultrasonic waveguide upon ultrasonic vibration of the ultrasonic waveguide. An excitation device is operable to ultrasonically excite the ultrasonic waveguide and the agitating member.
