[0045] In this example, the lower end of the spraying bin 1 is distributed with wheels 101 , and a handle 102 is installed on the side of the spraying bin 1 . The spraying bin 1 can be moved by holding the handle 102 and using the wheels 101 to achieve flexible transfer of the spraying bin 1 .

[0046] Working principle: According to Figure 1 and Figure 2 As shown, when the device is not in use, the injection port 103 is docked with the cover 3 to achieve sealing of the spray chamber 1, and the device is carried and moved by the shoulder strap 201. When the device is in use, the cover 3 is removed and the medicine barrel 6 is installed. When installing the medicine barrel 6, the handle 8 is held and docked with the injection port 103, and then the subsequent use and operation of the device can be started.

[0047] according to Figure 2and Figure 5 As shown, open the water filling cover 701 and pour water into the water filling port 7, observe the first scale 601 to control the water base in the medicine barrel 6, and then pour the medicine into the medicine liquid tank 9. Observe the amount of medicine through the second scale 901, then remove the squeezing rod 904 and push the second squeezing plate 903 on it into the medicine liquid tank 9. Open the third check valve 902 to pour the medicine into the medicine barrel 6. At this time, shake the device to evenly distribute the medicine.

[0048] according to Figure 2-7 As shown, the electric telescopic rod 5 is fully extended at the beginning, and the first extrusion plate 501 is close to the injection port 103 at the initial stage. As the electric telescopic rod 5 contracts, the first extrusion plate 501 moves downward, and the first check valve 104 is forced to open, driving the medicine in the medicine barrel 6 to be discharged from the rubber petal 603 and into the spraying chamber 1. At the same time, the second check valve 404 is sucked and closed. After the medicine injection is completed, the expansion of the electric telescopic rod 5 drives the first extrusion plate 501 to move upward. At this time, the first check valve 104 is pushed closed, and the second check valve 404 is opened by the impact force and injects the medicine into the liquid guide hose 401. Before use, the gooseneck tube 403 is turned to adjust the direction angle of the atomizing nozzle 402, and then the medicine is sprayed to the greening area through the atomizing nozzle 402 to complete the spraying of the medicine.
