Ultrasonic cleaning device with negative pressure absorption function

Abstract

The invention provides an ultrasonic cleaning device with the negative pressure absorption function. The ultrasonic cleaning device at least comprises an ultrasonic generator, a transducer, a housing body and two water pipes. An opening is formed in the front end of the housing body. The transducer is connected with the ultrasonic generator. The transducer comprises a working head and a body connected with the rear end of the working head. The working head is contained in the housing body. The front end face of the working head is close to the opening. A water storage region is arranged at the front end of the inner wall of the housing body. The water storage region communicates with the opening. One of the two water pipes is a water absorption pipe, and the other water pipe is a water supply pipe. The head end of one of the water pipes communicates with the water storage region. The head end of the other water pipe is close to the front end face of the working head of the transducer. By the adoption of the ultrasonic cleaning device with the negative pressure absorption function, continuous cleaning can be achieved, the cleaning effect is good, water resources are saved, and secondary pollution and pollution to the environment can be avoided.

Description

Technical field [0001] The invention relates to a cleaning device, in particular to an ultrasonic cleaning device with negative pressure absorption. Background technique [0002] Ultrasonic transducer is a device that realizes mutual conversion of electrical energy and sound energy (ie, high-frequency mechanical vibration energy). Ultrasonic cleaning is to generate ultrasonic vibration through a transducer, and instantaneous high-pressure cavitation generated by the cavitation effect in the water, which impacts the object to be cleaned to achieve a good cleaning effect. [0003] At present, the local cleaning technology using ultrasound mainly adopts submerged or water injection cleaning. In water immersion cleaning, the object to be cleaned must be immersed in water and then cleaned with an ultrasonic transducer; in water injection cleaning, water must be poured on the surface of the object to be cleaned, and the cleaned object must absorb a certain amount of water before cleanin...

AI Technical Summary

Problems solved by technology

These two cleaning methods will inevitably wet the position that does not need to be cleaned, which requires more water, wastes water resources, and is inconvenient to use; at the same time, the sewage generated during the cleaning process cannot be discharged in time, causing environmental pollution. Pollution, and prone to secondary pollution, requiring secondary cleaning or rinsing

In addition, since the object to be cleaned needs to be submerged in water before cleaning, or water is injected on the surface of the object to be cleaned, continuous cleaning cannot be performed, the use is inconvenient, and there are many limitations in the scope of application.
