DETAILED DESCRIPTION

[0014] The present invention includes a gun body, the front end of the gun body is a refueling pipe 2, and the rear end of the gun body is provided with a hook 22 and a handle 15, and is characterized in that: the refueling pipe 2 of the gun body is connected to the control cabinet 7 through a hose 5, and the control cabinet 7 is provided with a control module 8 and a refueling pipeline 10 connected to the hose 5; a liquid level sensor 1 is provided at the front end of the refueling pipe 2, and the liquid level sensor 1 is connected to the control module 8 in the control cabinet 7 through a signal line 6; an electromagnetic valve 9 and a booster pump 11 connected to the control module 8 are provided on the refueling pipeline 10; and a one-way valve 4 is provided in the gun body corresponding to the outlet of the hose 5.

[0015] As a preferred solution of the present invention, a refueling start-stop button 17 connected to the signal line 6 is provided on the gun body.

[0016] Furthermore, a protective cover 16 is provided on the gun body corresponding to the refueling start / stop button 17 .

[0017] As another preferred embodiment of the present invention, a signal wire tube 12 is provided on the refueling pipe 2, and the liquid level sensor 1 is provided at the end of the signal wire tube 12; the other end of the signal wire tube 12 is provided in the gun body; a sealing rubber head 13 is provided at the connection between the signal wire tube 12 and the cavity 3, one end of the signal wire in the gun body passes through the sealing rubber head 13 and is connected to the liquid level sensor 1, and the other end of the signal wire is connected to the wiring terminal 14 in the gun body; the wiring terminal 14 is connected to the signal line 6.

[0018] The end of the hose 5 is provided with a connector 21 , and the connector 21 is provided with a wire interface 20 of a signal line 6 , and the signal line 6 is attached to the hose 5 .

[0019] The cavity 3 is provided with a flange nut 19 matched with the connector 21; the inner opening of the flange nut 19 corresponds to the one-way valve 4; and a thrust spring 18 is provided between the one-way valve 4 and the gun body.

[0020] When the present invention is used, when refueling is not needed, the oil gun is hung on the refueling machine. When refueling is needed, the oil gun is removed from the refueling machine, and at this time, the booster pump 11 of the refueling machine is started. The oil gun is inserted into the refueling port of the automobile tank, and the refueling start-stop button 17 is pressed to send an opening signal, which is transmitted to the control module 8 of the refueling machine through the signal line. The control module 8 sends a command to open the solenoid valve 9. Due to the operation of the booster pump 11, the internal pressure of the hose 5 increases, and the pressure is transmitted to the one-way valve 4 of the refueling gun. When the pressure is greater than the elastic force of the thrust spring 18, the one-way valve 4 moves toward the outlet of the oil gun, the finished oil flow channel is opened, and the finished oil is filled into the automobile tank through the oil gun refueling pipe 2.

[0021] If the fixed-rate filling is adopted, after the required filling amount is reached, the control module 8 issues a command to close the solenoid valve 9, the pressure inside the hose 5 is reduced, and the one-way valve 4 moves toward the tail of the oil gun under the action of the thrust spring 18, the liquid flow channel is closed, and the filling is completed. The electric-controlled fueling gun is hung back on the fuel dispenser, and the booster pump 11 stops working.

[0022] If the filling method is adopted, the refueling start-stop button 17 is pressed, and the control module 8 sends a signal to the boost pump 11 and the solenoid valve 9, the boost pump 11 and the solenoid valve 9 are turned on, and the oil flows into the gun body along the oil supply pipeline 10 and the hose 5, pushes open the one-way valve 4, and then is injected into the fuel tank through the refueling pipe 2; when the oil fills the fuel tank, the liquid level sensor 1 sends a signal to the control module 8, and the control module 8 controls the solenoid valve 9 and the boost pump 11 to stop working; the thrust spring 18 closes the one-way valve 4 to complete the refueling stop action. The present invention has a simple and compact structure and a light weight, and can effectively prevent the gun body from leaking, and is safe and environmentally friendly.

Those skilled in the art should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the protection scope of the present invention.
