[0013] Gas stations refer to filling stations that serve cars and other motor vehicles and sell gasoline and oil, generally for adding fuel oil, lubricating oil, etc. Since the petroleum products sold at gas stations are flammable, volatile, leaky, and easy to accumulate static charges. The fuel gun is the terminal of the fuel tanker oil system and is the tool for refueling the receiving vehicle. It is easy to operate, the oil supply can be adjusted, and it is safe and reliable. The most common fuel gun used in the market is composed of the following parts: gland, fuel gun body, main valve, valve seat, cone, fuel gun nozzle, auxiliary valve, valve frame, switch handle, neck rod, movable joint, oil hose, steel ball and sealing ring.

[0014] Generally speaking, it is prohibited to use a refueling gun to refuel in insulating containers brought in privately by refueling personnel or insulated containers used by vehicle drivers in gas stations. The reason is that exposing the oil to the outside will increase the probability of refueling fire accidents. At the same time, when the insulating container filled with oil is reused after being taken out of the gas station, it will also cause safety hazards to the use of the oil outside the gas station.
