Rod transducer generating multi-dimensional ultrasonic wave in water

Abstract

The invention provides a rod transducer generating multi-dimensional ultrasonic wave in water. The rod transducer at least comprises a transducer body and an ultrasonic rod with a cavity, wherein thetail of the transducer body is provided with a water-proof joint, the water-proof joint is connected with an ultrasonic wave generator through a cable, and the head of the transducer body is connectedwith the tail of the ultrasonic rod. The rod transducer has a simple structure, the water-proof joint is connected with the ultrasonic wave generator through the cable, the head of the transducer body is connected with the tail of the ultrasonic rod, the ultrasonic rod is provided with a cavity, when the rod transducer is inserted or thrown into water, an outer wall or a free end face of the ultrasonic rod can be used as an emission end, so as to output ultrasonic energy in both axial and peripheral vibration modes, so that peripheral ultrasonic wave effect is improved greatly; compared withother rod transducers, the rod transducer needs to input less energy under equivalent ultrasonic effect; and the ultrasonic rod is provided with the cavity, so that the rod transducer is lighter.

Description

technical field [0001] The invention relates to a transducer, in particular to a rod transducer for generating multi-dimensional ultrasonic waves in water. Background technique [0002] An ultrasonic transducer is a device that converts electrical energy and sound energy (that is, high-frequency mechanical vibration energy). Ultrasonic cleaning is to generate ultrasonic vibration through the transducer, and the instantaneous high-pressure cavitation generated by the cavitation effect in the water impacts the object to be cleaned to achieve a good cleaning effect. [0003] Ultrasonic transducers can be simply divided into fixed ultrasonic transducers and movable ultrasonic transducers. The traditional movable ultrasonic transducer includes an ultrasonic transducer including a transducer body and a solid ultrasonic rod connected to the transducer body. The solid ultrasonic rod is a solid rod with a variable cross-sectional area, and the solid ultrasonic rod is realized by cha...

AI Technical Summary

Problems solved by technology

Because the solid ultrasonic rod is a solid rod with variable cross-sectional area, resulting in large mass and large vibration inertia, the traditional movable ultrasonic transducer is generally suitable for occasions with low frequency (such as 15-30KHZ) and high power

[0004] In addition, in terms of structural design, the solid ultrasonic rod needs to be designed separately from the transducer, and then used as a same frequency component to achieve resonance, resulting in a more complex overall structure and high cost
