Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic cleaning device. Background Art

[0002] Ultrasonic waves are sound waves with a frequency of more than 20kHz, which is beyond the human hearing range. The propagation of ultrasonic waves depends on elastic media. When propagating, they make the particles in the elastic medium oscillate and transfer energy through the medium in the direction of ultrasonic propagation. This wave can be divided into longitudinal waves and transverse waves. Ultrasonic cleaning uses the cavitation, acceleration and straight-forward flow of ultrasonic waves in liquids to directly and indirectly affect liquids and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. The current common method for cleaning experimental containers is to immerse the container to be cleaned in a cleaning tank filled with cleaning liquid. The energy generated by the ultrasonic transducer is transmitted to the cleaning process of the cleaning liquid through the bottom of the cleaning tank, but this cleaning method has poor cleaning effect and cannot better clean the inside of the container.
