Abstract
An ultrasonically activated water ejector includes a cylindrical water reservoir section configured to temporarily hold water, an ejection nozzle that ejects the water from a lower part of the water reservoir section, a dome-shaped ultrasonic vibration plate disposed in an upper part of the water reservoir section, facing the ejection nozzle, and having a concave spherical surface on a lower side thereof, and a water supply portion having a supply inlet configured to supply the water along the concave spherical surface into the water reservoir section from an outer periphery toward a center of the ultrasonic vibration plate. The water is supplied from the supply inlet to the water reservoir section in an amount greater than the water to be ejected from the ejection nozzle. The water flows along the concave spherical surface from the outer periphery toward the center, and is held in the water reservoir section.
