▎ 摘 要
NOVELTY - The generator has a trumpet-shaped frame (110) that is provided with an open lower surface and a hollow inner side. A first piezoelectric element (121) is attached to an outer surface of the frame, and a second piezo-electric element (122) is connected to the outer surface. A frequency band and intensity of voltage are applied to an anode of the first piezo element and an anodes of the second and third piezo electric elements. A vacuum generator (210) generates ultrasonic waves in a form of a spiral vortex. A piezo electrical portion is made of barium titanate, rossel salt, quartz and quartz, ceramic, plastic and graphene. A silver conductive material is coated from an inner surface to outer surfaces of the piezo electrically portion. USE - Ultrasonic generator for generating ultrasonic waves in the form of a swirling vortex. ADVANTAGE - The ultrasonic generator generates ultrasonic waves in the form of swirling vortex by controlling the frequency and intensity of voltage applied to the piezoelectric elements. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the ultrasonic generator and vacuum generator.
