[0003] At present, when people refuel at a gas station, if it is the peak period of refueling, there are many vehicles in the station, and one staff member needs to respond to multiple refueling devices. The staff usually leaves the current refueling device after inserting the refueling gun to refuel, and goes to the next vehicle to be refueled to refuel. During this period, the customer will return to the vehicle after completing the checkout. If the customer and the staff forget to pull out the refueling gun from the fuel tank, the customer will start the vehicle normally and drive away from the scene. At this time, the oil pipe will be broken and the refueling equipment will be damaged, so there is a certain safety hazard. Summary of the invention

[0005] To achieve the above-mentioned purpose, an embodiment of the present invention provides a novel fueling gun, comprising a fuel pipe, and a gun body, a safety device and a gun head all arranged on the fuel pipe;
[0006] The gun head includes an oil spray end and a clip for limiting the oil spray end from falling off when the oil spray end is inserted into the oil tank, the length of the clip is greater than the diameter of the oil tank port, the clip includes an insertion end at the top and a load-bearing end at the bottom, the insertion end extends into the oil tank and rests against the inner wall of the oil tank, and the load-bearing end rests against the outer wall of the oil tank;
[0007] The safety device comprises a pressure sensor, a shearing device and a controller for controlling the shearing component to cut off the oil pipe according to a sensing signal of the pressure sensor; the pressure sensor is arranged at the insertion end and is located on the fitting surface where the insertion end abuts against the oil tank;
[0008] The controlled end of the shearing device is electrically connected to the controller;

[0010] Compared with the prior art, the novel fueling gun disclosed in the present invention protects the fueling equipment through the disconnection mechanism technical solution of the safety device, and its practicality and safety are both strong.
[0011] As an improvement of the above solution, the safety device is located between the gun body and the gun head.

[0019] Specific beneficial effects:
[0020] 1. When the refueling gun is in normal use, the pressure value measured by the pressure sensor is the normal pressure value, which is lower than the preset safety pressure value. When an emergency occurs, the vehicle will pull the protruding end of the fastener through the inner wall of the fuel tank during the movement of the vehicle. This process will generate a gradually increasing pulling force, so the pressure value measured by the pressure sensor will gradually increase. When the pressure value measured by the pressure sensor is greater than the preset safety pressure value, the controller sends an execution instruction to the shearing device, and the shearing device cuts the oil pipe as a whole. At this time, the oil pipe is disconnected into two sections, one end follows the vehicle to detach, and the other end is still connected to the refueling equipment. The disconnection mechanism of the safety device protects the refueling equipment, and its practicality and safety are both strong;
[0021] 2. The position setting of the gun head can further protect the gun body. When the oil pipe is broken, the gun body is still fixed on the oil pipe connected to the refueling equipment;
[0022] 3. When the controller sends an execution instruction to the shearing device, it simultaneously sends an execution instruction to close the valves to the first valve and the second valve, thereby preventing the residual oil in the oil pipe from leaking out. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, Figure 1 is a schematic diagram of a specific structure of an embodiment of the present invention, Figure 2 is an internal structure diagram of a safety device in an embodiment of the present invention, Figure 3 yes Figure 2 Enlarged view of point A in the middle.
[0032] A novel fueling gun comprises a fuel pipe 1, a gun body 2, a safety device 3 and a gun head 4 which are all arranged on the fuel pipe 1.
[0033] The gun head 4 includes an oil spraying end 41 and a fastener 42 for preventing the oil spraying end 41 from falling off when the oil spraying end 41 is inserted into the oil tank. The length of the fastener 42 is greater than the diameter of the oil tank opening. The fastener 42 includes an insertion end 421 at the top and a load-bearing end 422 at the bottom. The insertion end 421 is inserted into the oil tank and abuts against the inner wall of the oil tank, and the load-bearing end 422 abuts against the outer wall of the oil tank.
[0034] The safety device 3 includes a pressure sensor 31, a shearing device 32, and a controller for controlling the shearing component to cut off the oil pipe 1 according to the sensing signal of the pressure sensor 31; the pressure sensor 31 is arranged at the insertion end 421 and is located on the fitting surface where the insertion end 421 abuts against the oil tank;
[0035] The controlled end of the shearing device 32 is electrically connected to the controller;
[0036] The output end of the pressure sensor 31 is electrically connected to the controller.
[0037] It should be noted that the shearing device 32 is a commonly used device in daily life. When the controller sends an execution instruction to the shearing device 32, the shearing device 32 cuts the oil pipe 1 as a whole, and the details are not described in detail.
[0038] For example, when using the refueling gun, the gun head 4 is inserted into the fuel tank, and the insertion end 421 of the clip 42 is inserted into the interior of the fuel tank, while the load-bearing end 422 is pressed against the outer wall of the fuel tank. At this time, the clip connection of the clip 42 inside and outside the fuel tank fixes the refueling gun on the refueling port. It should be noted that at this time, the pressure sensor 31 is located between the inner wall of the fuel tank and the insertion end 421, and measures the pressure between the insertion end 421 and the inner wall of the fuel tank in real time. Under normal circumstances, the formation of pressure is only the weight change of the refueling gun as a whole. At this time, the pressure value measured by the pressure sensor 31 is a normal pressure value. When the refueling gun is activated, a safety pressure value needs to be preset on the controller. The setting of this safety pressure value needs to refer to the pulling strength of the oil pipe 1 on the refueling gun, and the connection strength between the oil pipe 1 and the refueling equipment. The safety pressure value needs to be lower than the pulling force required for the oil pipe 1 to break and the pulling force for the connection between the oil pipe 1 and the refueling equipment to break.
[0039] At present, when people refuel at gas stations, if it is the peak period of refueling, there are many vehicles in the station, and one staff member needs to respond to multiple refueling devices. The staff usually leaves the current refueling device after inserting the refueling gun to refuel, and goes to the next vehicle to be refueled to refuel. During this period, the customer will return to the vehicle after completing the checkout. If the customer and the staff forget to pull the refueling gun out of the fuel tank, the customer will start the vehicle normally and drive away. At this time, the movement of the vehicle will cause a pull on the refueling gun.
[0040] For example, when the refueling gun is in normal use, the pressure value measured by the pressure sensor 31 is a normal pressure value, which is lower than the preset safety pressure value. When the above-mentioned emergency occurs, the vehicle will pull the insertion end 421 of the fastener 42 through the inner wall of the fuel tank during the movement of the vehicle. This process will generate a gradually increasing pulling force, so the pressure value measured by the pressure sensor 31 will gradually increase. When the pressure value measured by the pressure sensor 31 is greater than the preset safety pressure value, the controller sends an execution instruction to the shearing device 32, and the shearing device 32 cuts the oil pipe 1 as a whole. At this time, the oil pipe 1 is disconnected into two sections, one end follows the vehicle to detach, and the other end is still connected to the refueling equipment. Through the disconnection mechanism of the safety device 3, the refueling equipment is protected, and its practicality and safety are both strong.
[0041] More preferably, in this embodiment, the safety device 3 is located between the gun body 2 and the gun head 4. Such a position setting can further protect the gun body 2, and when the oil pipe 1 is broken, the gun body 2 is still fixed on the oil pipe 1 connected to the refueling equipment.
[0042] More preferably, in this embodiment, the safety device 3 further comprises a first valve 33 and a second valve 34 respectively arranged on both sides of the shearing device 32. The controlled ends of the first valve 33 and the second valve 34 are both electrically connected to the controller.
[0043] For example, when the controller issues an execution instruction to the shearing device 32 , it simultaneously issues an execution instruction to close the valves to the first valve 33 and the second valve 34 , thereby preventing the residual oil in the oil pipe 1 from leaking out.
[0044] More preferably, in this embodiment, the safety device 3 further comprises a first connector 35 and a second connector 36 connected to the oil pipe 1, and the first connector 35 and the second connector 36 are respectively arranged on both sides of the shearing device 32. With such an arrangement, after the oil pipe 1 is broken, the broken end can be replaced by the first connector 35 and the second connector 36, so that the safety device 3 can be recycled.
[0045] More preferably, in this embodiment, in order to protect the safety device 3, a protective sleeve is provided on the outer surface of the safety device 3, and the protective sleeve is disconnected from the shearing device 32 to both ends to form a first sleeve body 5 and a second sleeve body 6, and a connecting piece connected to the second sleeve body 6 is provided on the first sleeve body 5. In this embodiment, the connecting piece includes two strong magnets, and the two strong magnets are fixed on the first sleeve body 5 and the second sleeve body 6 respectively.
[0046] More preferably, in this embodiment, the gun body 2 is fixedly arranged on the second sleeve 6. The protective sleeve is penetrated through the oil pipe 1. The penetrated arrangement enables the first sleeve 5 to move on the oil pipe 1, which can facilitate the staff to perform daily maintenance on the internal safety device 3.
[0047] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
