Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and sound insulation, and more specifically, to a sound reduction cover for an ultrasonic cleaning machine. Background Art

[0002] The frequency of sound that humans can hear is 20-20000Hz. Usually, sound waves with a frequency higher than 20000Hz are called ultrasound. With the advancement of science and technology, ultrasound has been given more and more applications. In the cleaning industry, ultrasound also has a wide range of application scenarios. With the development of the cleaning industry, more and more companies have begun to use ultrasonic cleaning machines to clean products. The principle of ultrasonic cleaning machines is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the cleaning medium (ie, cleaning liquid). In the process of forward radiation, the ultrasonic wave causes the cleaning medium (liquid) to flow and generate a large number of tiny bubbles. The bubbles vibrate under the action of the sound field. These bubbles are formed and grow in the negative pressure area where the ultrasound propagates longitudinally. In the positive pressure area, when the sound pressure reaches a certain value, the bubbles will rapidly increase and then suddenly close.

[0003] At present, when an ultrasonic cleaning machine is working, bubbles inside it will generate a lot of noise. At the same time, when the bubbles burst, the liquid inside the ultrasonic cleaning machine will easily splash. In view of this situation, a cover is usually set on the upper end of the ultrasonic cleaning machine. When the ultrasonic cleaning machine is working, the vibration generated by the ultrasonic cleaning machine will cause the cover to move and shake, thereby making it easy to generate a lot of noise. In view of this situation, a sound-reducing cover for an ultrasonic cleaning machine is proposed. Utility Model Content
