Problems solved by technology

[0002] At present, the use of drones for pesticide spraying has gradually become a new popular technology due to its fast speed, low time-consuming, high efficiency and labor-saving features, but the traditional spraying hose of drones Most of them are directly fixed on the feet of the UAV, and in order to ensure the spraying demand, the drug pipe needs to be extended outside the UAV for spraying. The length of the pipe is long and takes up a large space, which will affect the flight. The position and length are fixed, which is inconvenient for storage and transportation, and it is very easy to interfere with the landing of the drone. The existing drone spraying device with folding function is easily affected by the airflow when spraying the liquid medicine However, if it is reversely poured into the drone body, it will cause dirt and corrosion to the body, and lacks a proper anti-blocking structure.

[0003] Notification number CN211543899U discloses a multi-rotor unmanned aerial vehicle portable folding spraying device and a multi-rotor unmanned aerial vehicle. The spraying device includes a medicine box, a fixed support, a first pole, a rotating mechanism and a spray nozzle. The tripod rod of the UAV is connected, the rotation mechanism is arranged on the fixed bracket, the first support rod is connected with the rotation mechanism, and the rotation mechanism can drive the first support rod on the UAV. One side of the extension end of the tripod rod is rotated with the side where the tripod rod body is located. The spray head is arranged on the first branch rod and connected to the medicine box through a pipeline. The nozzle of the folding spraying device lacks Anti-recoil structure for the spray, the mist liquid sprayed from the rear side is easily affected by the air flow and poured into the drone body in reverse
