Atomized liquid injection device

The utility model provides an atomized liquid injection device which comprises a medicament storage tank, a compressed gas storage tank and an injection system, wherein the injection system is provided with a connection opening and a jetting head; the medicament storage tank and the compressed gas storage tank are connected with the connection opening. High-speed compressed gas in the atomized liquid injection device can be used for atomizing liquids in any property, including fungicide and an oxidant, and even high-viscosity liquid can be atomized into homogenized aerosol. Components in atomized liquid are uniform and are high in penetrating power in the soil, and the affecting radius is much larger than that of injection liquid; the components are suitable for different soil properties. After being atomized, liquid forms extremely small liquid drops, and the specific surface area is greatly enlarged, so that the liquid drops can be in full contact with pollutants, and the treatment efficiency is obviously improved. The atomized liquid injection device is easy to operate and obvious in economical benefit.
