[0025] Reference Figures 1-3 This utility model embodiment proposes a precise solution mixing mechanism with a settable ratio, including a solvent tank 1. Two mounting plates 2 are fixedly connected to both sides of the top of the solvent tank 1, distributed front and rear. A pair of feeding ports 3 are installed on the top of the solvent tank 1. An openable cover 4 is installed in the middle of the top of the solvent tank 1 for removing foreign objects. A pair of stainless steel ball valves 5 are installed on the front side of the cover 4, located on the top of the solvent tank 1. A diaphragm assembly is connected to the front of the solvent tank 1. A high-pressure water flow meter 7 is installed on the front of the solvent tank 1. An electrical control assembly is connected to one side of the high-pressure water flow meter 7, and a delivery pipe 87 is connected to the other side of the high-pressure water flow meter 7. The high-pressure water flow meter 7 is model SM4100. Four pipe ports 9 are installed at the bottom of the solvent tank 1. The solvent tank 1 can be stably fixed by the mounting plates 2 on both sides of the top. The solvent tank 1 is mounted on the frame via mounting plate 2. A pair of feed ports 3 can be used for adding solvent. With the closable tank cover 4, it is convenient to add materials and reduces solvent evaporation. The stainless steel ball valve 5 is used to control the liquid level in the solvent tank. If the liquid level is too high or too low, a signal is triggered to drain or replenish water in time. The diaphragm assembly provides conditions for the independent delivery of two solvents. The two pipe ports 9 located on the left and right edges correspond to different chambers, which can discharge residual waste liquid in time and ensure the accuracy of subsequent mixing. The overall structure provides stable and convenient hardware support for the accurate mixing of solvents. The two pipe ports 9 located on the left and right edges are connected to the main drain through pipes. Each pipe in the main drain has an individual valve control. The delivery pipe 87 is used to connect to the external power mechanism for cleaning water source. The solvent tank 1 is divided into two chambers by a plate and stores different solvents.

[0026] The feed port 3 is designed in a funnel shape. The funnel shape of the feed port 3 increases the receiving area during feeding, which can effectively prevent solvent from spilling during the addition process and improve feeding efficiency.

[0027] The diaphragm assembly includes a pair of diaphragm pumps 61 that communicate with the solvent tank 1. One diaphragm pump 61 is connected to one end of a connecting pipe 62, and the other end of the connecting pipe 62 is connected to the inside of the solvent tank 1. The other diaphragm pump 61 is connected to one end of a connecting pipe 63, and the other end of the connecting pipe 63 is connected to the inside of the solvent tank 1. The pair of diaphragm pumps 61 are respectively connected to the connecting pipe 63 and the solvent tank 1 through the connecting pipe 62, realizing the independent delivery of the two solvents without interference. The diaphragm pump 61 is also connected to an external pipe for absorbing solvent into the solvent tank 1.

[0028] The electrical control assembly includes an inlet pipe 81, one end of which is connected to a motor 82. One end of a delivery pipe 83 is connected to the motor 82, and the other end of the delivery pipe 83 is connected to one end of a three-way connector 85. The other end of the three-way connector 85 is connected to a solenoid valve 86 via a pipe. The third end of the three-way connector 85 is connected to one end of a two-way connector via a pipe. The other two ends of the two-way connector are connected to small solenoid valves 84 via pipes. The two smaller solenoid valves 84, located on opposite sides, are connected to one end of a connecting pipe 88. The motor 82 provides the power source for fluid delivery, ensuring delivery stability. The arrangement of the three-way connectors 85 and 86 enables reasonable fluid diversion, simultaneously meeting the delivery requirements of two solvents. The two small solenoid valves 84 can precisely control the injection timing and switching of their respective solvents. With the auxiliary control of the solenoid valve 86, one end of which is connected to a heating box, hot water can be introduced to clean the pipes. Both solenoid valves are model ZCF-15SF-YJ112A.

[0029] The other ends of the two connecting pipes 3 88 are respectively connected to the two pipe ports 9 in the middle of the bottom of the solvent tank 1. The connecting pipes 3 88 are connected to the bottom of the solvent tank 1, which allows the solvent to flow out from the bottom of the solvent tank 1 and enter the conveying passage, thus minimizing the residue of solvent in the solvent tank 1.

[0030] Motor 82, high-pressure water flow meter 7, diaphragm pump 61, small solenoid valve 1 84, and solenoid valve 2 86 are all connected to the same electronic control unit. The electronic control unit can be used to control motor 82, high-pressure water flow meter 7, diaphragm pump 61, small solenoid valve 1 84, and solenoid valve 2 86. The electronic control unit is a Siemens S7-1200.

[0031] The specific implementation method is as follows: In use, two diaphragm pumps 61 absorb two different solvents through external pipes, and then transport them to two independent chambers separated by a plate in the solvent tank 1 through connecting pipe 1 62 and connecting pipe 2 63 respectively. At the same time, solvent can be added through the top funnel-shaped feeding port 3 to reduce spillage, and the tank cover 4 can be opened to remove foreign objects. Subsequently, the stainless steel ball valve 5 on the front side of the solvent tank 1 monitors the liquid level of the two chambers in real time. The stainless steel ball valve 5 triggers a signal to the electronic control unit to determine the liquid level and replenish it. Then, the electronic control unit can start the motor 82. The solvent in the two chambers of the solvent tank 1 flows out from the bottom middle pipe port 9 and enters the conveying passage through the corresponding connecting pipe 3 88. The fluid flows through the conveying pipe 1 83 to the inlet pipe 81, the high-pressure water flow meter 7, and the conveying pipe 2 87, and is transported to the outside for action. With the opening and closing of the two small solenoid valves 1 84, the solvent in the two chambers can be output separately, and the mixing ratio of the two solvents with hot water can be controlled to achieve precise proportioning.

[0032] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
