Description

Technical Field

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

[0002] Ultrasonic cleaning machines are mainly based on the high-frequency vibration of ultrasonic waves. The transducer converts this vibration into mechanical vibration, thereby generating tiny bubbles in the cleaning liquid. These bubbles vibrate under the action of sound waves. When the sound pressure reaches a certain value, the bubbles will rapidly increase and suddenly close, generating a powerful shock wave. This process can produce impacts on the surface of objects, removing dirt and impurities. This phenomenon is called the "cavitation" effect. During the cavitation process, the closure of bubbles will generate high temperatures of several hundred degrees and instantaneous high pressures of more than 1,000 atmospheres, which can destroy insoluble dirt and disperse them in the cleaning liquid. It can also emulsify oil stains and separate solid particles from the surface of objects, thereby achieving the purpose of cleaning.

[0003] In some existing ultrasonic cleaning machines, the high-frequency vibration of ultrasonic waves is converted into mechanical vibration through the transducer, thereby generating tiny bubbles in the cleaning liquid. These bubbles vibrate under the action of sound waves. When the sound pressure reaches a certain value, the bubbles will rapidly increase and suddenly close, generating a powerful shock wave. This process can generate impact on the surface of the object and remove dirt and impurities;
