Description

Technical Field

[0001] The utility model relates to the technical field of fuel dispensers, in particular to a fuel dispenser suitable for low-temperature areas. Background Art

[0002] The basic function of a fuel dispenser is to add fuel to motor vehicles and to accurately measure the added fuel. A fuel dispenser can add diesel or gasoline to motor vehicles. A fuel dispenser is composed of a fuel gun, a fuel hose, a valve and other components. However, climatic conditions in different regions and seasons may affect the performance of the fuel dispenser and may require additional maintenance and attention.

[0003] Cold temperatures can cause the density of the liquid (fuel) to change, which may affect the accuracy of the measurement. Fuel dispensers are usually equipped with temperature sensors to correct the measurement results and ensure accurate fuel metering at different temperatures. At the same time, at low temperatures, the fuel and parts of the fuel dispenser may freeze, causing pipe blockages or obstructing the flow of fuel. To solve this problem, some fuel dispensers are equipped with heating systems to prevent ice and freezing.

[0004] However, in actual use, existing equipment will heat the fuel dispenser components and cover the outside of the oil hose with insulation materials to prevent abnormalities when used in low-temperature areas. However, when the oil hose is too long to transport oil and diesel, diesel contains wax components, which are easily affected by temperature and condense into wax in low-temperature areas. The insulation effect of the oil hose is limited by insulation materials, which reduces the stability of the fuel dispenser in transporting diesel in low-temperature areas. In view of this, we propose a fuel dispenser suitable for low-temperature areas. Utility Model Content

[0015] Compared with the prior art, the utility model provides a fuel dispenser suitable for low-temperature areas, which has the following beneficial effects:

[0016] 1. The fuel dispenser suitable for low-temperature areas can drive the annular shell to move to any position on the surface of a long hose by being provided with a fixed ring. The oil inlet pipe cooperates with the oil outlet pipe to add or discharge heat-conducting oil to the oil storage chamber. The electric heating pipe heats the heat-conducting oil so that the hose is no longer in a low-temperature state for diesel transportation. The telescopic pull plate drives the connecting block to move manually through the concave handle. The two sets of springs are extended and retracted so that the moving magnetic block drives the toggle ring to stir the heat-conducting oil through the force of magnetic attraction, so that the heated heat-conducting oil flows inside the oil storage chamber, accelerates the speed at which the temperature inside the annular shell increases, and then insulates the hose, avoids waxing due to the long hose being affected by low temperature during diesel transportation, and improves the stability of the fuel dispenser in a low-temperature environment.

[0017] 2. The fuel dispenser suitable for low-temperature areas is provided with a contact rod to squeeze the toggle ring when it moves back and forth. After the shaft is stressed, it rotates inside the installation groove to stretch the coil spring. The toggle ring moves away from the contact rod, and the coil spring rebounds to reset the toggle ring. Then, the toggle ring moves back and forth inside the oil storage chamber to stir the heat transfer oil while rotating to a certain extent, so that the heat transfer oil flows in multiple directions, thereby quickly increasing the temperature of the oil storage chamber, thereby shortening the speed of the first heating of the annular shell.

[0027] In one embodiment of the utility model, the outer surface of the hose 2 is slidably connected to the inner surface of the fixing ring 4, the end of the fixing ring 4 is fixedly connected to the end of the annular shell 8, the inner wall of the annular shell 8 is fixedly connected to the end of the partition plate 9, the outside of the partition plate 9 is provided with a heat preservation plate 10, the outer surface of the partition plate 9 is in contact with the outer surface of the electric heating pipe 11, the top of the annular shell 8 is provided with an oil inlet pipe 12, the bottom of the annular shell 8 is provided with an oil outlet pipe 13, the outer surface of the heat preservation plate 10 is slidably connected to the bottom of the moving magnetic block 14, the bottom of the moving magnetic block 14 is provided with a following magnetic block 15, the bottom of the following magnetic block 15 is provided with a rotating shaft 24, the end of the rotating shaft 24 is fixedly connected to the top of the toggle ring 16, the top of the moving magnetic block 14 is fixedly connected to the bottom of the connecting block 17, the side wall of the connecting block 17 is fixedly connected to the end of the spring 18, the other end of the spring 18 is fixedly connected to the inner surface of the opening 27, the top of the opening 27 is provided with a telescopic pull plate 19, and the top of the telescopic pull plate 19 is provided with a concave handle 20.

[0028] In one embodiment of the utility model, the electric heating tube 11 is located on the side opposite to the partition plate 9 and the insulation plate 10, the toggle ring 16 is sleeved on the outer wall of the partition plate 9, the surface of the annular shell 8 is provided with an opening 27, and the opening 27 is blocked by the telescopic pull plate 19, and the two ends of the telescopic pull plate 19 are configured to be stretchable and contractible, and the moving end of the telescopic pull plate 19 can move on the surface of the annular shell 8, the top of the connecting block 17 is fixedly connected to the bottom of the moving end of the telescopic pull plate 19, and a group of springs 18 are provided on both sides of the connecting block 17, and the bottom of the fixed end of the telescopic pull plate 19 is fixedly connected to the outer surface of the annular shell 8, and the top of the following magnetic block 15 is slidably connected to the inside of the slide groove 21, and the bottom of the following magnetic block 15 An installation groove 23 is opened, and the inner wall of the installation groove 23 is fixedly connected with the moving end of the coil spring 25, and a contact rod 26 is arranged on the outer side of the slide groove 21. The inner surface of the insulation board 10 is opened with the slide groove 21. The insulation board 10 is made of polystyrene board. The polystyrene board has excellent thermal insulation and sound insulation effects and can be used as a thermal insulation material for the heat transfer oil pipeline. At the same time, the polystyrene board is light and will not increase the overall weight of the hose 2. The inner surface of the insulation board 10 is fixedly connected with the end of the contact rod 26, and the fixed end of the coil spring 25 is fixedly connected with the outer surface of the rotating shaft 24. The end of the rotating shaft 24 away from the toggle ring 16 is rotatably connected to the inner wall of the installation groove 23, and the gap between the insulation board 10 and the partition plate 9 forms an oil storage cavity.

[0029] In the present invention, when the refueling machine 1 is used in a low-temperature area, the annular shell 8 is first pulled to make the two sets of fixing rings 4 slide on the surface of the hose 2, so that the annular shell 8 is in a position relatively centered by the hose 2. At this time, the heat transfer oil is poured into the interior of the oil storage chamber through the oil inlet pipe 12, and the electric heating tube 11 is turned on to heat the interior of the oil storage chamber. After heating, the temperature of the heat transfer oil increases, so that the partition plate 9 transfers the heat source to the surface of the hose 2 after being heated, and the surface of the hose 2 is kept warm to avoid waxing due to the long length of the hose 2 when refueling in low-temperature areas. At the same time, the inner recessed handle 20 is manually inserted into the inside, and the moving end of the telescopic pull plate 19 is pulled left and right, so that the telescopic pull plate 19 drives the connecting block 17 to move inside the opening 27, and the two sets of springs 18 stretch and contract accordingly, and then the moving magnetic block 14 moves back and forth on the outside of the insulation plate 10. Movement, due to the arc-shaped magnetic attraction between the moving magnetic block 14 and the following magnetic block 15, the following magnetic block 15 drives the toggle ring 16 to move back and forth inside the oil storage chamber inside the slide groove 21, so that the heat transfer oil accelerates the flow inside the oil storage chamber. When the toggle ring 16 moves to the left or right side, it will fit with the contact rod 26. The contact rod 26 squeezes the moving toggle ring 16, so that the toggle ring 16 drives the rotating shaft 24 to rotate a certain amplitude, and the coil spring 25 is stretched accordingly. When the contact rod 26 is no longer in contact with the toggle ring 16, the coil spring 25 restores the elastic force to drive the toggle ring 16 to reset and continue to move inside the oil storage chamber, so that the toggle ring 16 irregularly stirs the heat transfer oil, thereby expanding the heating effect of the annular shell 8 on the hose 2, so that the diesel will not be waxed due to low temperature during transportation, thereby improving the stability of the fuel dispenser 1 in low temperature areas.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
