[0038] Working principle: When the spray gun needs to be used for a long time, first, the water inlet pipe 9 is matched with the water storage tank 3 to add water, and the water source is matched with the outer wall of the oil storage tank 1. When the spray gun is used for a long time, the surface temperature of the water source will heat up the water source. At this time, the temperature of the water source is checked by the thermometer 4, which is convenient for the operator to observe. After that, the servo motor 17 fixedly connected to the hollow column 16 is started, and the wind force generated by the rotation of the fan blades 18 blows to the bottom end of the outer wall of the oil storage tank 1 to effectively reduce the temperature of the oil storage tank 1. Finally, the heat sink 15 is matched to cool the oil storage tank 1, so that the spray gun can withstand high temperature environment.
