Abstract

The invention discloses an ultrasonic transducer. The ultrasonic transducer comprises a lower cover, a first electrode plate, first piezoelectric ceramic, a second electrode plate, second piezoelectric ceramic and an upper cover which are sequentially arranged from bottom to top, wherein the lower cover, the first electrode plate, the first piezoelectric ceramic, the second electrode plate, the second piezoelectric ceramic and the upper cover are locked and fixed through bolts penetrating through the axis from bottom to top, the ultrasonic transducer is characterized in that a cover cap is fixedly installed at the top of the upper cover, the upper end face of the cover cap is a vibration generating face, and the vibration generating face is a protruding face gradually protruding upwards from the edge to the center or an arc face protruding towards the middle from the two sides. According to the ultrasonic transducer, the structure of a traditional ultrasonic transducer is adjusted, thevibration generating face of the ultrasonic transducer is changed from a plane to a convex surface with a certain height, and the sound intensity of the ultrasonic transducer is improved.

Description

Technical field [0001] The present invention relates to an ultrasonic transducer TECHNICAL FIELD particular to a surface oscillation is arcuate or tapered ultrasonic transducer. Background technique [0002] Currently, the ultrasound transducer is mainly used for cleaning, and in particular that the ultrasonic transducer is mounted at the bottom of the tank, and the tank is close to the oscillation plane, away from the other parts of the tank. In this process, an ultrasonic transducer under the control of the ultrasonic generator, the electrical energy into mechanical energy and then emit ultrasound, high frequency ultrasonic waves to vibrate a liquid medium compression, so that the liquid molecules generated alternating positive and negative shock wave. When the ultrasonic sound intensity reaches a certain value, the liquid fine cavitation bubbles grow abruptly and instantaneously strongly closed, a strong micro-explosion shock wave and the surface to be cleaned of dirt destruct...
