As the volume of fuel in the fuel tank increases, excess air in the fuel tank is vented through the fuel tank vent port into the vent tube 200 and eventually out through the vent tube 200 to the environment to maintain the air pressure balance between the filler tube of the vehicle and the fuel tank.

According to the automobile oil filling pipe provided by the embodiment of the disclosure, by arranging the anti-overflow assembly consisting of the oil storage tank 310, the first valve 320 and the second valve 330, when the automobile oil filling pipe is in a normal use state, both the first valve 320 and the second valve 330 are in a closed state. When the fuel amount of the fuel gun is too high due to the error of workers, and the fuel flows backwards from the fuel delivery pipe 100, the first valve 320 is controlled to be communicated, so that the fuel flowing backwards from the fuel delivery pipe 100 can flow into the fuel storage tank 310 through the first valve 320, and the fuel is prevented from being directly sprayed out from the fuel delivery pipe 100. After the vehicle runs and consumes, when the fuel level in the oil delivery pipe 100 is reduced and lower than the second joint 120, that is, after the fuel completely falls back into the oil tank of the vehicle, the first valve 320 is controlled to be closed, the second valve 330 is controlled to be opened, so that the residual oil in the oil storage tank 310 is refilled into the oil tank of the vehicle through the second joint 120, and the air in the oil storage tank 310 can be discharged to the outside through the exhaust pipe 311, so as to maintain the pressure balance between the oil storage tank 310 and the oil tank of the vehicle, so that the fuel can smoothly enter the oil storage tank 310 and be refilled into the oil tank of the vehicle from the oil storage tank 310, and the anti-overflow operation of the oil filling pipe of the vehicle is realized.

Wherein the relatively high end of reservoir 310 communicates with first connector 110 via first valve 320 and the relatively low end communicates with second connector 120 via second valve 33. When the fuel is poured from the fuel delivery pipe 100 due to the excessive filling amount of the fuel gun caused by the mistake of the operator, that is, the fuel to be poured from the fuel delivery pipe 100 flows into the fuel storage tank 310 through the first valve 320, most of the fuel is gathered to the end of the fuel storage tank 310 communicating with the second joint 120. And the exhaust pipe 311 is arranged at the end of the oil storage tank 310 connected with the first valve 320, namely the end of the oil storage tank 310 with a relatively high height, so that on the basis of ensuring that redundant air in the oil storage tank 310 is exhausted, the blockage caused by the fact that fuel oil flowing into the oil storage tank 310 from the first valve 320 flows into the exhaust pipe 311 can be avoided, and the conduction effect of an automobile oil filling pipe is improved.

Optionally, exhaust pipe 311 is in communication with vent pipe 200. Exemplarily, in the embodiment of the present disclosure, by communicating the exhaust pipe 311 with the vent pipe 200, the air in the oil storage tank 310 can directly pass through the vent pipe 200 to the outside, and it is not necessary to separately provide an exhaust port communicated with the exhaust pipe 311 for exhausting air, which is simple in structure and convenient to manufacture, and improves the practicability of the oil filling pipe of the automobile.

Optionally, the oil filling pipe of the automobile further comprises a filter screen 500, and the filter screen 500 is disposed at the connection position of the exhaust pipe 311 and the vent pipe 200.

For example, in the disclosed embodiment, when the fuel filler pipe of the vehicle is in a normal use state, the first valve 320 and the second valve 330 are both in a closed state. When the fuel injection amount of the fuel gun is too high due to the error of workers, and the fuel is poured back from the fuel delivery pipe 100, the liquid level sensor 610 on the second joint 120 senses that the fuel in the fuel tank of the automobile flows back into the fuel delivery pipe 100 through the second joint 120, and the controller 620 controls the first valve 320 to be switched on, so that the fuel poured back from the fuel delivery pipe 100 can flow into the fuel storage tank 310 through the first valve 320, and the fuel is prevented from being directly sprayed out from the fuel delivery pipe 100. After the vehicle runs and consumes, when the fuel level in the oil delivery pipe 100 is reduced and is lower than the second joint 120, the liquid level sensor 610 senses that the fuel completely falls back into the oil tank of the vehicle, namely the first valve 320 is controlled to be closed, and the second valve 330 is controlled to be conducted, so that the residual oil in the oil storage tank 310 is simultaneously refilled into the oil tank of the vehicle through the second joint 120, and the anti-overflow operation on the oil filling pipe of the vehicle is completed.
