A medicine inlet is fixedly connected to the front side of the top of the sealing tank cover 2. Water is injected from the lower water inlet pipe 5 and the upper water inlet pipe 6, and the medicament is injected into the mixing tank 1 from the medicine inlet pipe.

[0026] Referring to Figure 2 and Figure 3 ,the rotation gear ring 9 fixedly connected to the bottom side of the sealed tank cover 2, and rotation gears 11 are fixedly connected to the top ends of the stirring rods 10. The outer walls of the two rotation gears 11 on the separated sides are meshed with the inner wall of the rotation gear ring 9. A driving motor 3 is fixedly connected to the middle of the top side of the sealed tank cover 2. The driving end of the driving motor 3 is fixedly connected to the top end of the driving rod 7. The driving motor 3 drives the driving rod 7 to rotate. The rotation of the driving rod 7 drives the stirring rod 10 to revolve around the driving rod 7 to stir the medicament and water. While the two stirring rods 10 revolve around the driving rod 7, the rotation gear 11 rotates with the stirring rod 10 and meshes with the rotation gear ring 9 to drive the stirring rod 10 to rotate; both the front and rear sides of the bottom of the outer wall of the driving rod 7 are fixedly connected with cleaning scrapers 8. At the same time, the driving rod 7 drives the cleaning scrapers 8 to stir the medicament to make the mixing of the medicament more sufficient. After the purification is completed, the inner wall of the mixing tank 1 can also be cleaned;

[0027] Referring to Figure 4 and Figure 5 ,the connection limit ring 12 fixedly connected to the top side of the fixed slider 13. A plurality of slots are opened in the inner wall of the connection limit ring 12. Second springs 15 are arranged inside the slots. The closer ends of the plurality of second springs 15 are fixedly connected to the separated sides of the plurality of limit insertion blocks 16. The separated ends of the plurality of second springs 15 are fixedly connected to the inner walls of the separated sides of the plurality of slots.

The closer sides of the limit insertion blocks 16 are inserted into the bottom side of the outer wall of the upper water inlet pipe 6. One ends of the plurality of first springs 14 are fixedly connected to the bottom side of the fixed slider 13, and the other ends of the plurality of first springs 14 are fixedly connected to the bottom side of the inner wall of the chute. Hold the connection limit ring 12 and slide it down. The downward sliding of the connection limit ring 12 drives the fixed slider 13 to press down and compress the first spring 14. The limit insertion block 16 drives the second spring 15 to be compressed as the connection limit ring 12 slides down, releasing the connection between the lower water inlet pipe 5 and the upper water inlet pipe 6, and removing the upper water inlet pipe 6 to replace the filter screen at the connection of the upper water inlet pipe 6 and the lower water inlet pipe 5.

[0028] Working principle: When it is necessary to mix the medicament and water, the water is injected from the lower water inlet pipe 5 and the upper water inlet pipe 6, and the medicament is injected into the mixing tank 1 from the medicine inlet pipe; the driving motor 3 is started to drive the driving rod 7 to rotate. The rotation of the driving rod 7 drives the stirring rod 10 to revolve around the driving rod 7 to stir the medicament and water. While the two stirring rods 10 revolve around the driving rod 7, the self-rotating gear 11 rotates with the stirring rod 10 and meshes with the self-rotating gear ring 9 to drive the stirring rod 10 to rotate self. At the same time, the driving rod 7 drives the cleaning scraper 8 to stir the medicament to make the mixing of the medicament more sufficient. The purified water is discharged from the discharge pipe 4. When the filter screen needs to be cleaned and replaced after long-term use, hold the connecting limit ring 12 and slide it down. The sliding down of the connecting limit ring 12 drives the fixed slider 13 to press down and compress the first spring 14. The limit insertion block 16 drives the second spring 15 to be compressed as the connecting limit ring 12 slides down, releasing the connection between the lower water inlet pipe 5 and the upper water inlet pipe 6, and removing the upper water inlet pipe 6 to replace the filter screen at the connection of the upper water inlet pipe 6 and the lower water inlet pipe 5. After the filter screen replacement is completed, insert the upper water inlet pipe 6 back onto the lower water inlet pipe 5, release the connecting limit ring 12, and the first spring 14 rebounds to drive the connecting limit ring 12 to reset. At the same time, the limit insertion block 16 is displaced to the slot at the bottom of the upper water inlet pipe 6, and the second spring 15 rebounds to drive the limit insertion block 16 to reset to fix the upper water inlet pipe 6.
