[0035] As Figures 1 to 9 shown, the present application provides a vehicle fuel heating device, including a car tank body 100, a first cavity 400, a flow regulating mechanism 1300, an engine output shaft 1400 and a second cavity 500, the bottom of the inner cavity of the car tank body 100 is fixedly connected with a fixed block 200, a vacuum heat insulation cavity 300 is arranged in the inside of the fixed block 200, the top of the inner cavity of the fixed block 200 is fixedly connected with a double-ring heat conduction pipe 1100, the inner cavity of the middle part of the fixed block 200 is movably connected with a limiting plug 600, a through hole 700 is formed in the top of the inside of the limiting plug 600, a first corrugated pipe 900 is fixedly connected below the through hole 700 in the inside of the limiting plug 600, a second corrugated pipe 1000 is fixedly connected on one side of the first corrugated pipe 900 in the inside of the through hole 700, an electric heating wire 800 is fixedly connected on the side of the limiting plug 600 close to the double-ring heat conduction pipe 1100, and a heating regulating mechanism 1200 is arranged on one side of the car tank body 100; by operating the electric heating wire 800, since the amount of water source stored in the inner cavity of the second cavity 500 is small, the electric heating wire 800 will quickly heat the water source in the inner cavity of the second cavity 500, at the same time, the heat conduction effect of the double-ring heat conduction pipe 1100 on the water source in the second cavity 500 will heat the gasoline in the inner cavity of the double-ring heat conduction pipe 1100, and at the same time, due to the effect of the through hole 700, when the water source in the second cavity 500 is heated, the heat of the water source in the second cavity 500 will be transferred to the water source in the inner cavity of the first cavity 400, at this time, the water source in the inner cavity of the first cavity 400 will preheat the gasoline in the inside of the first corrugated pipe 900, thereby improving the heating speed of the device on the gasoline when starting and saving the energy consumed by the device when heating.

[0036] As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the inner cavity of the fixed block 200 and the side of the limiting plug block 600 away from the double-ring heat conduction pipeline 1100 form a first cavity 400, the side of the limiting plug block 600 close to the double-ring heat conduction pipeline 1100 and the inner cavity of the fixed block 200 form a second cavity 500, the first cavity 400 and the second cavity 500 are both added with water source, the first cavity 400 and the second cavity 500 are communicated through the through hole 700, the top of the automobile oil tank body 100 is also provided with an oil outlet, the bottom of the electric heating wire 800 close to the side of the through hole 700 is fixedly connected with the second corrugated pipe 1000, and the two are communicated with each other, the double-ring heat conduction pipeline 1100 is located in the inside of the second cavity 500, one end of the top of the first corrugated pipe 900 penetrates through the top of the fixed block 200 and extends into the inner cavity of the automobile oil tank body 100, the end of the electric heating wire 800 away from the through hole 700 is fixedly connected with the fixed block 200, and the electric heating wire 800 is elastic, and the electric heating wire 800 is located on the side close to the inside of the double-ring heat conduction pipeline 1100; through the design of the double-ring heat conduction pipeline 1100, the contact area of the water source in the inner cavity of the second cavity 500 and the double-ring heat conduction pipeline 1100 is increased, so that the device facilitates the rapid heating of gasoline in the double-ring heat conduction pipeline 1100, and at the same time, after the electric heating wire 800 heats the water source in the second cavity 500, the heat of the water source in the second cavity 500 is diffused into the water source in the inner cavity of the first cavity 400 through the through hole 700, so that the preheating effect of the gasoline in the first corrugated pipe 900 is achieved, and the heating speed of the gasoline by the double-ring heat conduction pipeline 1100 is improved.

[0037] It is worth mentioning here that the heating of the electric heating wire 800 only needs to maintain the temperature of the water source in the inner cavity of the second cavity 500, thereby reducing the volume of gasoline that needs to be heated by the electric heating wire 800, thereby reducing the energy of the device when heating the gasoline, saving resources.

[0038] Example 2

[0039] As Figures 1 to 9As shown, the heating adjusting mechanism 1200 comprises a fixed pipe 1201 arranged at one side of the automobile oil tank body 100 and fixedly connected to the automobile oil tank body 100 at the top, a sealing transmission block 1202 movably clamped in the inner cavity of the middle part of the fixed pipe 1201, a transmission belt 1203 in transmission connection with the outer surface of the sealing transmission block 1202, a spline shaft 1204 clamped in the inner cavity of the sealing transmission block 1202, a turbine blade 1205 fixedly connected to the outer surface of the spline shaft 1204 close to one side of the automobile oil tank body 100, a limiting rod 1206 movably connected to the inner cavity of the fixed pipe 1201 close to one side of the automobile oil tank body 100, an elastic spring 1207 sleeved on the outer surface of the limiting rod 1206, a ball 1208 fixedly connected to the inner cavity of the limiting rod 1206 away from the elastic spring 1207, a first heat insulation pipe 1209 fixedly connected to the inner cavity of the bottom of the fixed pipe 1201 close to one side of the automobile oil tank body 100, and a second heat insulation pipe 1210 fixedly connected to the inner cavity of the top of the fixed pipe 1201. Through the rotation of the engine output shaft 1400, the transmission belt 1203 is driven to rotate, and then the sealing transmission block 1202 drives the spline shaft 1204 to rotate, so that the turbine blade 1205 rotates, thereby sucking the preheated gasoline in the second cavity 500 into the inner cavity of the fixed pipe 1201 through the first heat insulation pipe 1209 and outputting the gasoline from the end of the fixed pipe 1201 away from the automobile oil tank body 100. When the engine runs faster, the speed of the engine output shaft 1400 is greater, so that the speed of the sealing transmission block 1202, the spline shaft 1204 and the turbine blade 1205 driven by the sealing transmission block 1202 is faster, thereby increasing the amount of gasoline transported from the fixed pipe 1201. When the turbine blade 1205 rotates under the action of the output gasoline thrust, the turbine blade 1205 drives the spline shaft 1204 to extrude the ball 1208 and push the limiting rod 1206 to move towards the side close to the fixed block 200, thereby pushing the limiting plug 600 to move away from the limiting rod 1206, so as to increase the volume of the inner cavity of the second cavity 500 and the length of the second bellow 1000, thereby increasing the amount of heating of the gasoline in the second cavity 500 to meet the oil supply operation of the engine at high speed.

[0040] As Figures 1 to 9As shown, the sealing transmission block 1202 is in transmission connection with the engine output shaft 1400 through the transmission belt 1203, and the sealing transmission block 1202 is in interference fit with the inner cavity of the fixed pipeline 1201, the spline shaft 1204 is located in the inner cavity of the fixed pipeline 1201 and does not contact with the inner cavity of the fixed pipeline 1201, the outer surface of the turbine blade 1205 is in movable connection with the inner cavity of the fixed pipeline 1201, the limiting rod 1206 is fixedly connected with the limiting plug block 600 at one end close to the limiting plug block 600, the limiting rod 1206 is sleeved in the inner part of the electric heating wire 800, the ball 1208 is in contact with the spline shaft 1204 at one end close to the spline shaft 1204, the first heat insulation pipeline 1209 penetrates through the bottom of the automobile oil tank body 100 and the fixed block 200 at one end away from the fixed pipeline 1201, and is in communication with the inner cavity of the second cavity 500, the first heat insulation pipeline 1209 is in communication with the inner cavity of the fixed pipeline 1201, the second heat insulation pipeline 1210 penetrates through the side wall of the automobile oil tank body 100 at one end of the top and is in communication with the inner cavity of the middle part of the automobile oil tank body 100, and the second heat insulation pipeline 1210 is in communication with the inner cavity of the fixed pipeline 1201 at one end of the bottom; through the design of the elastic spring 1207, the resetting action of the limiting rod 1206 and the limiting plug block 600 when the engine output shaft 1400 stops running is facilitated, and through the design of the second heat insulation pipeline 1210, when the rotating speed of the engine output shaft 1400 is too fast to make the turbine blade 1205 rotate too fast, at this time, the rate of gasoline delivery in the fixed pipeline 1201 will also increase, at this time, the second heat insulation pipeline 1210 will deliver the gasoline in the fixed pipeline 1201 which fails to be delivered to the inside of the automobile oil tank body 100.

[0041] Example 3

[0042] As Figure 6As shown, the flow regulating mechanism 1300 comprises a tapered cylinder 1301, an inner cavity of the tapered cylinder 1301 is movably connected with an outer surface of the spline shaft 1204 away from the automobile oil tank body 100, the fixed pipe 1201 is provided with a tapered cavity 1302 and a third cavity 1303 respectively at an inner part away from the automobile oil tank body 100, a gap is left between the tapered cylinder 1301 and the slope of the tapered cavity 1302, the diameter and length of the third cavity 1303 are greater than the diameter and length of the largest part of the tapered cylinder 1301, the third cavity 1303 and the tapered cavity 1302 are in communication with the fixed pipe 1201, one half of the outer surface of the tapered cylinder 1301 is located in the inner cavity of the fixed pipe 1201 away from the spline shaft 1204, and a gap is left between them; when the spline shaft 1204 moves towards the fixed block 200, the spline shaft 1204 will also drive the tapered cylinder 1301 to move towards the fixed block 200, so that the gap between the tapered cylinder 1301 and the tapered cavity 1302 is increased, and the gap between the side of the tapered cylinder 1301 located in the fixed pipe 1201 and the fixed pipe 1201 is also increased, thereby increasing the interface of the gasoline passing through the tapered cavity 1302, so as to achieve the effect of regulating the gasoline delivery amount.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it.
