The china misting fog machine is driven by a gasoline engine to drive a centrifugal fan to rotate at a high speed to generate a high-speed airflow to realize airflow powder transfer, air pressure infusion and pneumatic atomization. Motorized plant protection equipment powered by gasoline engines. Its main structure: frame, centrifugal fan, gasoline engine, fuel tank, medicine box and spray device and other components.

1. The frame is generally made of bent steel pipes. There are also engineering plastic frames to reduce the weight of the whole machine. The structural form, rigidity and strength of the frame directly affect the reliability, vibration and other performance indicators of the backpack.

2. Centrifugal fan The fan is one of the important components of the china misting fog machine, generally a small high-speed centrifugal fan. Its function is to generate a high-speed airflow, to break the liquid medicine into a mist or blow the powder away, and send it to a distance. The airflow enters the fan from the axial direction of the impeller, and the high-speed airflow after obtaining energy flows out along the tangential direction of the impeller circumference. At present, it is divided into front-bending fans and backward-bending fans.
