[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Compared with manned aircraft, they have the advantages of small size, low cost and ease of use. Drones are often used in agriculture for pesticide application.

[0003] According to a publicly disclosed drone spraying device (Announcement No.: CN216232992U), the above application sets up a stirring frame and utilizes the rotation of the stirring frame to mix the pesticide to ensure the uniformity of the pesticide dissolution. However, during the rotation process, the stirring frame rotates in the same direction for a long time. The long-term unidirectional rotation of the stirring frame will generate centrifugal force, causing the different components in the pesticide solution to be stratified according to density differences, resulting in uneven distribution of the pesticide in the container, affecting the consistency of the pesticide concentration during subsequent atomization spraying. In actual spraying, the concentration of the active ingredient of the pesticide sprayed may be low in the initial stage, and the concentration may suddenly increase in the later stage, making it impossible to ensure stable efficacy. To address this problem, we have proposed an atomization spraying device for drones. Utility Model Content
