Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more particularly to a self-cleaning and recycling device for cleaning fluid suitable for cleaning machines. Background Technology

[0002] Ultrasonic cleaning devices utilize high-frequency oscillation signals emitted by an ultrasonic generator, which are converted into high-frequency mechanical oscillations by a transducer and propagated into the cleaning solution. The ultrasonic waves radiate forward in the cleaning solution with alternating high and low density, causing the liquid to flow and generating tens of thousands of tiny bubbles. These bubbles form and grow in the negative pressure zone created by the longitudinal long wave of the ultrasonic waves and then rapidly close in the positive pressure zone. In this process known as "cavitation," the closure of the bubbles can create instantaneous high pressure exceeding 1000 atmospheres. The continuously generated high pressure is like a series of small "explosions" that constantly impact the surface of the object, causing dirt on the surface and in the crevices to be quickly peeled off, thereby achieving the purpose of cleaning the object's surface.

[0003] For example, CN202316372U discloses a vacuum cleaning machine cleaning fluid recovery device, including a cleaning tank and a recovery tank. The cleaning tank is connected to the recovery tank via an output pipe, and the recovery tank is connected to the cleaning tank via an input pipe. A pump is installed on the input pipe, and filter devices are installed on both the output pipe and the input pipe between the pump and the recovery tank. A magnet is installed in the filter device on the output pipe. However, although this device achieves cleaning and recycling of the cleaning fluid, the flow rate of the cleaning fluid from the recovery tank to the cleaning tank via the input pipe is small, and the time is long, which seriously affects the work efficiency. In addition, the cleaning fluid flowing from the cleaning tank to the recovery tank contains oil stains. If these are not treated, it will affect subsequent processing, making it impossible to guarantee the cleanliness of the workpieces in the cleaning tank and affecting the yield rate.

By controlling the contact between the chamber body and the bottom of the chamber, the cleaning fluid can be stored, facilitating the cleaning of the workpiece by the ultrasonic oscillator located on the bottom of the chamber. After cleaning, the chamber body separates from the bottom of the chamber, allowing for the transfer of the support plate. This operation is simple, convenient, stable, and reliable, greatly improving work efficiency. Furthermore, the cooperation between the sliding shaft and the bushing improves the stability of the chamber body's movement and enhances the precision of the seal between the chamber body and the bottom of the chamber, preventing cleaning fluid leakage and improving safety.
