Problems solved by technology

[0003] In the field of ultrasonic cleaning technology, if the current piezoelectric transducer is used for cleaning, due to the single vibration direction, a standing wave will be generated between the bottom of the cleaning tank and the liquid level of the liquid in the cleaning tank, and the standing wave will have nodes. There is no vibration at the wave node, and it is easy to form a cleaning dead angle, resulting in incomplete cleaning

Abstract

The invention belongs to the technical field of transducers, and relates to a multidirectional vibration ultrasonic transducer, an ultrasonic cleaning device and cleaning method. The transducer comprises a base, a vibration cover and a vibration column arranged in an inner cavity of the vibration cover; a sealing vibration isolation layer is arranged between the vibration cover and the base; and the vibration cover is of a hollow cylindrical structure and is inversely arranged on the base to be connected with the base to form a closed cavity structure, the top of the vibration column is connected with the center of the vibration cover, the vibration column is excited to generate vibration which is transmitted to the vibration cover, and the vibration cover radiates composite vibration formed by alternating longitudinal axisymmetric bending vibration and radial transverse vibration. The transducer is simple in structure, small in size, capable of generating composite vibration formed by alternating longitudinal axisymmetric bending vibration and radial transverse vibration, free of cleaning dead angles, high in ultrasonic frequency and good in cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of transducers, and relates to an ultrasonic transducer vibrating in multiple directions, an ultrasonic cleaning device and a cleaning method. Background technique [0002] Piezoelectric transducers are currently the main type of ultrasonic vibration transducers, among which piezoelectric ceramics are mostly used. Since ceramics are easy to process into the required shape, their components and processes can be changed to meet the high performance requirements of various purposes. Therefore, it is widely used; polarized piezoelectric ceramics generate stretching vibration under the excitation of periodic signals, and transmit the vibration through the vibrating rod to realize the conversion of electrical energy and mechanical energy. Most of the existing piezoelectric transducers have a single vibration direction, usually a single vibration, that is, longitudinal vibration or bending vibration. [0003] In t...
