The rotation of the transmission shaft 3 drives the stirring impeller 4 to start rotating. Before treatment, water is passed into the treatment box 2. As the liquid level rises, the inverted buoy 6 is driven to move upward on the supporting slide bar 5. The supporting slide bar 5 limits the inverted buoy 6, and then drives the adjusting slide bar 7 to move upward, lifts one end of the rotating card plate 9, and rotates on the rotating frame 8. The rotating card plate 9 rotates to drive the telescopic slide bar 13 to move downward, and drives the sealing slide plate 11 to move downward on the inner wall of the drug storage cylinder 10. Sliding, when the liquid level is stable, the sealing slide plate 11 no longer moves down, and the metering sensor 12 senses the height of the sealing slide plate 11 moving down, and then feeds back to the metering valve 15, controlling the corresponding amount of liquid medicine to enter the medicine storage cylinder 10.

The reset spring 16 lifts the telescopic slide bar 13 upward after the medicine is used. The nozzle 17 sprays the medicine in the treatment box 2 after the medicine is completely poured into the medicine storage box 26. At this time, the transmission shaft 3 also rotates, driving the stirring impeller 4 to start rotating, accelerating the mixing of the medicine and water. The limit spring 18 cooperates with the fixed clamp ring 20 and the sliding clamp ring 19 to limit the inverted buoy 6, so that the inverted buoy 6 can be on a reference plane to prevent it from being stuck on the surface of the transmission shaft 3, further improving the adaptability of use.

When working, the motor barrel 21 is fixed to the inner wall of the treatment box 2 for installing the built-in motor 22. When the built-in motor 22 is working, it drives the transmission shaft 3 to rotate through the output shaft. The feed port 23 is used for feeding, and the discharge port 24 discharges the treated water out of the treatment box 2. The medicine storage box 26 is filled with liquid medicine, which can be discharged into the liquid storage cylinder through the liquid guide tube 14. In this process, the discharge amount of the liquid medicine is controlled by the metering valve 15 to ensure the accuracy of the addition of the liquid medicine.

This process may cause certain deviations in the liquid medicine, making the efficiency of the final water treatment still need to be improved. When working, the base 1 is placed to support the treatment box 2, and the transmission shaft 3 can rotate on the inner wall of the treatment box 2. The rotation of the transmission shaft 3 drives the stirring impeller 4 to start rotating. Before treatment, water is passed into the treatment box 2. As the liquid level rises, the inverted buoy 6 is driven to move upward on the supporting slide bar 5. The supporting slide bar 5 limits the inverted buoy 6, thereby driving the adjusting slide bar 7 to move upward, and the rotating card One end of the plate 9 is lifted up and rotates on the rotating frame 8. The rotating card plate 9 drives the telescopic slide rod 13 to move downward, driving the sealing slide plate 11 to slide downward on the inner wall of the medicine storage cylinder 10. When the liquid level is stable, the sealing slide plate 11 no longer moves downward. The metering sensor 12 senses the height of the downward movement of the sealing slide plate 11, and then feeds back to the metering valve 15 to control the corresponding amount of liquid medicine to enter the medicine storage cylinder 10. In addition, the height of the medicine storage cylinder 10 is higher than the height of the telescopic slide rod 13. When the medicine enters the medicine storage cylinder 10, the sealing slide plate 11 moves downward until the telescopic slide rod 13 supports the sealing slide plate 11. This process realizes the effect of controlling the amount of medicine, ensures the accuracy of dosing, and thus improves the efficiency of water treatment. The top of the adjusting slide rod 7 is adapted to the adjusting slide rod 7 to drive the rotating card plate 9 to move The return spring 16 brings the telescopic slide bar 13 upward after the use of the medicine liquid, and the nozzle 17 sprays the medicine liquid in the treatment box 2 after the medicine liquid is completely poured into the medicine storage box 26. At this time, the transmission shaft 3 also rotates, driving the stirring impeller 4 to start rotating, accelerating the mixing of the medicine liquid and water, and the limit spring 18 cooperates with the fixed clamping ring 20 and the sliding clamping ring 19 to limit the inverted buoy 6, so that the inverted buoy 6 can be on a reference plane to prevent it from being stuck on the surface of the transmission shaft 3, further improving the adaptability of use, the motor cylinder 21 is fixed to the inner wall of the treatment box 2, and is used to install the built-in motor 22. When the built-in motor 22 is working, it drives the transmission shaft 3 to rotate through the output shaft. The feed port 23 is used for feeding, and the discharge port 24 discharges the treated water out of the treatment box 2. The medicine storage box 26 is filled with medicine liquid, which can be discharged into the liquid storage cylinder through the liquid guide tube 14. In this process, the discharge amount of the medicine liquid is controlled by the metering valve 15 to ensure the accuracy of the addition of the medicine liquid. By setting the inverted float 6, as the water level increases, the inverted float 6 will start to move up, thereby driving the adjusting slide bar 7 to move up, and then driving the rotating card plate 9 to rotate, and then cooperate with the telescopic slide bar 13 to drive the sealing slide plate 11 to slide on the inner wall of the medicine storage cylinder 10. When the liquid level does not increase, the sealing slide plate 11 no longer slides. At this time, the metering sensor 12 and the metering valve 15 start to work, and the medicine liquid enters the medicine storage cylinder 10 through the liquid guide tube 14, and the corresponding amount is controlled by the metering valve 15 to achieve the effect of controlling the amount of medicine, ensure the accuracy of dosing, and thus improve the efficiency of water treatment.
