[0010] By adopting the above technical solution, the water for mixing with the medicine and the water inside the medicine barrel are extracted through the setting of the extraction component and sprayed through the support component; Throw the filter and pure water pipe into the water, open control valve 4 and control valve 2, and close control valve 1 and control valve 3; The pump starts and the water pumping end pumps water in through the medicine water pipe, control valve 4, and pure water pipe. The filter screen can filter impurities during the pumping process. The pump discharges the water into the base through the middle pipe, control valve 2, and water adding pipe. The medicine is put into the medicine barrel through the medicine adding port. The drive motor starts and its output end drives the stirring shaft to rotate. The stirring shaft drives the stirring blades to rotate to stir and mix the water and the medicine. When spraying the medicine, close the control valve 4 and the control valve 2, and open the control valve 3 and the two control valves 1; When the pump is started, its water pumping end directly draws the water and medicine mixture inside the medicine barrel through the medicine water pipe, and the pumped water and medicine mixture is discharged into the middle pipe through the pump. The middle pipe transports the mixture to two connecting hoses. After the mixture enters the connecting hose, it enters the connecting pipe and finally sprays it out in the form of mist through the atomizing nozzle. The user can push the setting to move.

When the output end of the driving motor rotates, the pulley 1 drives the stirring shaft to rotate, and the stirring shaft drives the limit bolts, the connecting seat and the pulley 1 to rotate; Since the medicine and water are mixed before spraying, they are no longer stirred during the spraying process. Therefore, during the spraying process, the purpose of the rotation of the pulley 1 is to drive the rotation of the pulley 2 through the belt. The rotation of the pulley 2 can drive the threaded rod to rotate, and the rotation of the threaded rod can drive the support component to move up and down to adjust the position of the connecting pipe. The position of the connecting pipe is adjusted by mixing the medicine and water first; the height of the connecting pipe after positioning is not affected by stirring; If stirring is only performed, the limit bolt does not need to be connected to the limit connection seat with the slot.
