[0031] Reference Figure 1 - Figure 3 The control mechanism includes a knob 6, and the circumferential surface of the knob 6 is provided with an anti-skid key pattern to increase the friction between the palm and the knob 6, reduce the possibility of slipping, and save effort. The bottom of the knob 6 is fixedly connected with a threaded rod 7, and the front of the circular plate 5 is fixedly connected with a fixed block 8 with a rectangular cross-section. The threaded rod 7 penetrates and is rotatably mounted on the inner wall of the fixed block 8. The control mechanism also includes a slider 9, which is threadedly mounted on the circumferential surface of the threaded rod 7. The displacement direction of the slider 9 is the radial direction of the threaded rod 7. A slide groove 10 is provided on the front of the circular plate 5. The slider 9 is slidably mounted on the inner wall of the slide groove 10. The slide groove 10 is used to guide the displacement of the slider 9 so that the slider 9 can make a more precise linear motion during displacement, thereby improving the stability of the slider 9 during movement. The control mechanism also includes a connecting rod 11. One end of the connecting rod 11 is hinged to the front face of the slider 9, and the other end of the connecting rod 11 is hinged to a shift rod 12 arranged in a horizontal state. When the threaded rod 7 rotates one circle, the displacement distance of the slider 9 is fixed, so the maximum displacement distance of the piston 13 can be fine-tuned by controlling the number of rotations of the threaded rod 7 to improve the accuracy of control.

[0032] Reference Figure 1 , Figure 3The feeding mechanism includes a piston 13, which is fixedly mounted on the left side of the shift rod 12.

[0033] Reference Figure 4 The stirring mechanism includes a drive motor 18, which is fixedly installed at the bottom of the tank body 1. The drive motor 18 is used to provide power.

[0034] Working principle: when in use, add diluent into the hopper 15, then start the power of the stepper motor 4, the stepper motor 4 works to drive the circular plate 5 to rotate, the rotation of the circular plate 5 drives the connecting rod 11 to move, the movement of the connecting rod 11 squeezes or pulls the shift rod 12, so that the shift rod 12 makes a horizontal linear reciprocating motion on the inner wall of the liquid tank 14, the movement of the shift rod 12 drives the piston 13 to make a linear reciprocating motion, the movement of the piston 13 cooperates with the one-way valve 16 and the one-way valve 2 17 to press the diluent inside the hopper 15 into the tank body 1, when the diluent pressed into the tank body 1 reaches the required amount, stop the stepper motor 4, at this time, the diluent inside the liquid tank 14 is lifted by the pressure relief valve 21, to prevent the diluent from entering the tank body 1 under the action of gravity, resulting in inaccurate concentration of chemical dilution inside the tank body 1, further improving the control accuracy of chemical dilution concentration.

[0035] By turning the knob 6, the rotation of the knob 6 drives the threaded rod 7 to rotate, and the rotation of the threaded rod 7 drives the slider 9 to move in the axial direction of the threaded rod 7. The displacement of the threaded rod 7 will adjust the distance between the right side of the connecting rod 11 and the center of the circular plate 5, thereby adjusting the displacement distance of the piston 13 inside the liquid tank 14, and the speed of injecting the diluent into the tank body 1 can be controlled, thereby accurately controlling the dilution concentration of the chemicals, improving the accuracy of the control, and ensuring that the quality of the dilution of the chemicals meets the requirements.
