Description

Technical Field

[0001] The invention relates to the technical field of vector control, in particular to a spraying and disinfecting device for vector control. Background Art

[0002] Vectors are organisms that can spread diseases quickly, seriously affecting people's health. Therefore, in order to reduce the spread of vectors, pesticide spraying is usually used to prevent and control vectors. Therefore, the use of pesticide spraying devices is essential. During work, the inventor found that the height and direction of the nozzle of the existing spraying device are fixed when in use, resulting in a limited spray coverage.

[0003] For example, the existing Chinese patent document CN202223402993.4 discloses a spraying and disinfecting device for vector control, which controls the rotation of the lifting tube by a screw rod, and the lifting tube is limited by the slider and the slide rail, so that the lifting tube moves up and down, drives the spray plate to rise and fall, and adjusts the height of the spray plate. The rotating motor drives the gear 2 and the spray plate to rotate through the gear 1, and adjusts the direction of the spray plate to fully meet the needs of spraying. At the same time, the existing Chinese patent document CN202220767344.5 discloses a drug spraying device for vector control, which makes the atomizing nozzle swing left and right continuously when spraying drugs, thereby increasing the range of drug spraying, reducing the number of times the operator walks, and reducing the work intensity of the operator;

[0004] Although the disinfection devices in the above two solutions can achieve the effect of expanding the spraying range of the drug, they need to be driven by corresponding control of the lifting and rotating directions. However, since these devices use a screw lifting method, their lifting speed is relatively slow, resulting in low overall efficiency in the actual spraying process. This low efficiency may become a bottleneck in large-scale disinfection operations, affecting the overall operation progress and effect. Therefore, although these disinfection devices perform well in expanding the spraying range, there is still room for improvement in improving spraying efficiency. Summary of the invention
