[0002] In garden planting, it is necessary to spray liquid medicine on the plants inside the garden from time to time to achieve the purpose of pest control through the liquid medicine. However, at some higher tree crowns, it is inconvenient for users to climb, so users will install drone spraying equipment at the bottom of the drone to carry out spraying. Most of the existing drone spraying devices will use atomizing nozzles to spray the liquid medicine inside the water tank.

Although some nozzles can rotate to spray, they all need to have an independent power source to drive the nozzles, which consumes a lot of power and significantly reduces the endurance of the drone. In this regard, we propose a drone spraying device to solve the above problems. Utility Model Content
