[0027] Compared with the prior art, this utility model provides a water circuit structure for ultrasonic rinsing, which has the following beneficial effects:

[0028] This invention improves the water circuit structure for ultrasonic rinsing. When using this structure, the transducer, the first water pump body, and the second water pump body are first connected to an external power source. Then, the object to be rinsed is placed inside the cleaning tank. The cleaning machine body converts high-frequency electrical energy into mechanical vibration through the transducer, which is then transmitted to the cleaning fluid through the tank wall. The cavitation, mechanical, and thermal effects in the cleaning fluid work together to peel, disperse, and dissolve dirt from the surface of the object, thus achieving the cleaning purpose. After rinsing, the third water pump body is activated. The cleaning fluid in the tank enters the filter tank through the first outlet pipe, the sixth connecting pipe, the sixth inlet pipe, the sixth outlet pipe, the first connecting pipe, and the first inlet pipe. The cleaning fluid then passes through a coarse filter, a fine filter, an activated carbon filter layer, and a fiber filter layer. This multi-layered filter effectively intercepts impurities and contaminants in the cleaning fluid. The concentration monitoring device, installed on the left wall of the second storage tank, uses a sensor plate... The system uses a data acquisition chip, an analysis chip, and a main control chip to monitor the concentration of the cleaning solution. When the concentration of the cleaning solution is below standard, the first water pump is activated. The high-concentration cleaning solution inside the first storage tank enters the filter tank through the third outlet pipe, the third connecting pipe, the third inlet pipe, the second outlet pipe, the second connecting pipe, and the second inlet pipe, where it combines with the substandard cleaning solution to bring it up to standard. The setup of the first water pump and the first storage tank increases the concentration of the cleaning solution, thereby enhancing the cleaning quality. Then, the second water pump is activated, which transports the cleaning solution inside the filter tank to the cleaning tank through the fifth connecting pipe, the fifth inlet pipe, the fourth outlet pipe, the fourth connecting pipe, and the fourth inlet pipe, thus enabling the reuse of the cleaning solution. The coordinated use of the first water pump, the second water pump, the third water pump, the first storage tank, the second storage tank, the filter tank, the placement tank, the concentration monitoring device, and multiple outlet pipes, inlet pipes, and connecting pipes enhances the recycling of the cleaning solution.
