Description

Technical Field

[0001] The present invention relates to the technical field of fuel dispensers, and in particular to a high-precision flow control anti-cheating fuel dispenser. Background Art

[0002] The background technology of fuel dispensers covers fuel pumping, precise metering, safety protection and environmental protection. With the development of electronic control and automation technology, modern fuel dispensers integrate functions such as automatic payment, oil and gas recovery, and remote monitoring, and adopt explosion-proof, anti-static design and anti-fraud measures to ensure operational safety and data security. In addition, the development of new energy has promoted the expansion of fuel dispensers towards multi-fuel compatibility, including electric vehicle charging and natural gas and hydrogen fuel filling equipment, thereby realizing a more efficient, environmentally friendly and intelligent fuel filling system.

[0003] When the gas station cannot use high-precision flow control, it will lead to increased metering errors, causing consumers to get more or less fuel, affecting the user experience and causing economic losses. In addition, the risk of fuel waste and environmental pollution increases, which may cause safety accidents such as oil spills and leaks, while also increasing equipment wear and maintenance costs and shortening equipment life. Lack of precise flow control can also lead to inaccurate inventory management, affecting the operational efficiency and decision-making of gas stations, and having a negative impact on safety, efficiency and economy as a whole.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a high-precision flow control anti-cheating fuel dispenser to solve the above technical problems. Summary of the invention

[0005] The technical purpose to be achieved by the present invention is: a high-precision flow control anti-cheating fuel dispenser drives the rotating column to rotate when the impeller rotates, thereby causing the centrifugal rod to move outward, and the moving centrifugal rod pushes the sliding block to move vertically. The vertical movement of the sliding block drives the rotating rod to rotate by rotating the slider, and finally, the rotating rotating rod causes the sealing disk to rotate, thereby adjusting the flow rate of the fuel in the oil pipe.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions: The present invention provides a high-precision flow control anti-cheating fuel dispenser, comprising a base, a fuel dispenser and a baffle, wherein the fuel dispenser is installed at the upper end of the base, and the baffle is installed above the fuel dispenser. The fuel dispenser drives an impeller to rotate through the flow of fuel, and the rotating impeller drives a rotating column to rotate. The rotation of the rotating column drives a centrifugal rod to move outward, and the moving centrifugal rod drives a sliding block to move vertically. The vertically moving sliding block drives a rotating rod to rotate by rotating a sliding block, so that the rotating rotating rod drives a sealing disk to rotate, and the rotating sealing disk adjusts the flow rate of fuel in the oil pipe.

[0007] The flow of fuel drives the impeller to rotate, and then the sealing disk is adjusted through a complex linkage mechanism to control the size of the opening in the oil pipe. This precise mechanical transmission structure can ensure the accuracy of flow control, thereby reducing errors in fuel flow and improving refueling accuracy. This automatic adjustment mechanism ensures that the fuel can maintain a stable flow output at different flow rates without complex manual intervention, thereby improving the automation and convenience of the refueling process. The present invention is based on pure mechanical principles and avoids complex electronic components, which not only reduces the maintenance cost and failure rate of the equipment, but also improves durability. Mechanical components are easy to maintain and replace, and are particularly suitable for high-frequency use scenarios such as gas stations. The fuel dispenser is equipped with a heating device to ensure that the fuel inside the fuel dispenser in cold areas will not freeze. The heating system maintains the fluidity of the fuel and can work normally even in low temperature environments, thereby improving the environmental adaptability and reliability of the equipment. In addition, the automatic resetting of the centrifugal rod is achieved through a clockwork device. When the fuel stops flowing, the clockwork mechanism restores the device to its initial position to prepare for the next refueling. The automatic resetting function ensures the stability and consistency of the refueling process, which can improve the reliability of the fuel dispenser under long-term operation and is suitable for high-frequency use scenarios.

[0008] The fuel dispenser includes a fuel tank, a display panel, a fuel pipe, a control ring and a fuel gun. The fuel tank is installed on the upper end of the base, the display panel is installed on the side of the fuel tank, fuel pipes are installed at both ends of the fuel tank, a control ring is installed inside the fuel pipe, a fixed pipe is installed in the inner array of the control ring, a fixed cylinder is installed at the other end of the fixed pipe, an impeller is rotatably installed on the upper end of the fixed cylinder, a rotating column is fixedly installed on the upper end of the impeller, the cross-sectional shape of the rotating column is T-shaped, and a fuel gun is installed at one outer end of the fuel pipe.

[0009] By installing a control ring inside the oil pipe and combining it with structures such as a fixed pipe, a fixed cylinder and a rotating impeller, precise control of the flow of fuel can be achieved. The impeller rotates with the flow of fuel, driving mechanical structures such as the rotating column to adjust the flow. Compared with traditional fuel dispensers, this design can more efficiently adjust and control the flow rate of fuel and improve refueling efficiency. The rotating column adopts a T-shaped cross-section design, which can effectively increase the stability of the rotating column and enable it to rotate more smoothly under the drive of the impeller. The T-shaped structure provides a larger force-bearing area and stronger support, which helps to extend the service life of the rotating column and the overall device and reduce mechanical wear. The linkage design of the control ring and the impeller inside the device allows the flow rate to be automatically adjusted when the fuel flows, ensuring a smooth and accurate flow process. The outer side of the oil pipe is directly connected to the refueling gun to form an integrated design, which reduces connectors or intermediate equipment and improves the convenience of operation. At the same time, this design makes the refueling operation smoother, reduces the possible risk of leakage, and improves the overall aesthetics of the equipment. The setting of components such as the fixed cylinder and the fixed pipe ensures the firmness of the overall structure and improves the durability of the device. In addition, the impeller, rotating column and other components are optimized to adapt to different environmental conditions, including use in low-temperature environments. Combined with the heating device mentioned above, the fuel dispenser can maintain normal operation in cold areas to prevent the fuel from freezing.

[0010] Both ends of the side surface of the rotating column are provided with opening grooves for rotating outward to limit sliding, the cross-section of the opening groove is U-shaped, and a fixed column for limiting rotation is installed on the opening groove.

[0011] The design of the U-shaped support groove can effectively limit the sliding range of the centrifugal rod, making the movement of the centrifugal rod more controlled and preventing unnecessary sliding or shaking. In this way, the entire transmission mechanism can run more smoothly, especially under high-speed rotation or severe vibration conditions, ensuring the stability and operation accuracy of the mechanical structure. In addition, the support groove limits the sliding of the centrifugal rod, reducing excessive friction and wear during the rotation process. This helps to extend the service life of the rotating column and related mechanical parts, reduce the maintenance cost of the equipment, and has significant durability advantages, especially in the case of long-term and high-frequency use. The U-shaped support groove provides a precise track for the rotating column, allowing it to rotate within a fixed range and maintain a stable direction. By limiting the angle and range of rotation by fixing the column, it is possible to prevent deviation during the rotation process, thereby improving the rotation accuracy of the entire mechanical device, ensuring precise control of the oil pipe opening and accurate regulation of the fuel flow. The structure of the U-shaped support groove is relatively simple and can be easily adjusted or maintained.

[0012] Limiting rings are provided at both ends of the fixing column, a mainspring is installed inside the limiting ring, and the mainspring rotates counterclockwise.

[0013] When the dispenser stops working or the fuel stops flowing, the spring will restore the centrifugal rod to its initial position through its elastic action. This automatic reset function ensures that the initial state can be maintained after each operation, ready for the next refueling operation, and improves the working efficiency and convenience of the equipment. The counterclockwise pullback force generated by the spring can pull the rotating column or related components back to their designed initial position in time when the fuel flow stops, avoiding damage to the components or inaccurate operation caused by continued rotation due to inertia or external force. The counterclockwise rotation and reset function of the spring can prevent the components from deviating from the predetermined position due to inertia during the operation of the equipment. By keeping each component within the set range of motion, the wear between the parts is reduced and the service life of the equipment is extended. In addition, the automatic reset function reduces the intervention of the operator and improves the stability of the equipment.

[0014] A sliding block is installed on the rotating column, and the cross-sectional shape of the sliding block is H-shaped. An extrusion block for downward extrusion is installed at the lower end of the sliding block, and the cross-sectional shape of the extrusion block is T-shaped.

[0015] The cross section of the H-shaped sliding block provides a larger contact surface and good guidance. Compared with other shapes, the H-shaped sliding block is more stable during movement, reducing the jamming or irregular sliding caused by friction or offset. This ensures that the sliding block remains stable during longitudinal movement and avoids errors, thereby improving the accuracy and reliability of the equipment. The combined design of the H-shaped sliding block and the T-shaped extrusion block can evenly distribute the force. Driven by the rotating column, the sliding block and the extrusion block will not experience stress concentration when subjected to force, which can avoid local wear or deformation and extend the service life of the equipment components. The T-shaped cross-sectional design of the extrusion block makes it more efficient in transmitting the extrusion force. The T-shaped structure provides a larger force-bearing area, which can better transmit the movement force of the sliding block to other components, thereby achieving precise regulation of the oil pipe flow. The H-shaped sliding block is closely combined with the rotating column. The H-shaped cross-sectional design prevents the sliding block from offsetting during movement. The sliding block is limited by the guide groove when moving up and down, and is not easy to shake left and right, which enhances the accuracy of movement. At the same time, the T-shaped extrusion block provides good directional control when applying the extrusion force, avoiding rotational instability during operation. The H-shaped sliding block and the T-shaped extrusion block cooperate with each other to make the power transmission process smoother, ensuring that the movement of the rotating column can be efficiently converted into the control of the fuel flow in the oil pipe. This design can improve the response speed of the equipment, allowing the fuel dispenser to quickly adjust the flow under different refueling requirements and improve the user experience.

[0016] L-connecting rods are installed at both ends of the T-shaped extrusion block, one end of the centrifugal rod is installed on the L-connecting rod, the other end of the centrifugal rod is spherical, and the material of the centrifugal rod is made of polyvinyl chloride, the centrifugal rod is installed on the fixed column, and the outer end of the mainspring is installed inside the centrifugal rod, a heating box is installed on the outer side of the control ring, and a heating tube is connected to the end of the heating box close to the control ring, the heating tube passes through the fixed tube, the impeller and the sliding block, and the heating tube is located in the rotating column.

[0017] The connection between the centrifugal rod and the L-link allows the centrifugal force to generate mechanical force through rotation, thereby driving the vertical movement of the sliding block. This control method based on mechanical linkage ensures the accuracy of flow regulation and avoids the uncertainty caused by complex electronic control systems. The centrifugal rod is made of polyvinyl chloride material, which is lightweight and has excellent corrosion resistance and avoids the generation of static electricity. Polyvinyl chloride materials can maintain good chemical stability when facing chemical substances such as fuel, are not prone to corrosion or wear, and greatly improve the durability of the equipment. In addition, the weight of PVC material is light, which reduces the load during rotation. A heating box is installed on the outside of the control ring. The heating box heats the fuel through a heating pipe to ensure that the fuel dispenser can still work normally in low temperature or cold environments. The heating pipe runs through the fixed pipe, impeller and sliding block, and is located in the rotating column, making the fuel heating process efficient and uniform. The fuel can be kept within the appropriate temperature range, reducing the flow resistance and improving the fluidity of the fuel. This makes the flow rate of the fuel more stable during the refueling process, reduces the refueling time, and improves the overall refueling efficiency, which is particularly suitable for applications in cold areas. Relying on mechanical transmission to control the fuel flow, and completing the reset and control actions through physical forces such as centrifugal force and springs, reducing the dependence on electronic components and electricity. Compared with purely electronic control systems, mechanical control systems have lower energy consumption and lower failure rates. They also have higher reliability and service life, which helps reduce long-term use costs.

[0018] A U-shaped block is installed on the periphery of the sliding block, and a rotating slider is rotatably installed between the U-shaped blocks. The cross section of the rotating slider is T-shaped, and the four corners of the upper end of the rotating slider are chamfered.

[0019] The outer periphery of the U-shaped block provides additional support, ensuring that the sliding block and the rotating slider are more stable during operation. The tight fit between the U-shaped blocks effectively prevents the sliding block from loosening or displacement, increasing the mechanical reliability of the overall structure. The rotating slider adopts a T-shaped cross-section design, which can effectively reduce friction when rotating between the U-shaped blocks. The T-shaped structure is characterized by having fewer contact surfaces, which can reduce friction resistance during rotation and make rotation smoother. The four corners of the rotating slider are designed as chamfers, which helps to avoid sharp friction or jamming between the edges and other parts during rotation. The chamfer design makes the edges of the slider smoother, which not only improves the smoothness of the movement of mechanical parts, but also avoids damage or wear caused by sharp corners. This helps to reduce maintenance requirements and extend the service life of the equipment. The combination of the U-shaped block and the T-shaped rotating slider ensures that the slider can move smoothly within the preset track when subjected to force, greatly improving the precise control ability of the mechanical system. This structure provides higher precision for flow regulation of the oil pipe and avoids flow control errors caused by misalignment of mechanical parts or excessive friction. The combination of the U-block and T-slide improves the operating efficiency of the entire fuel dispenser by reducing friction and improving sliding smoothness. The rotating slide can easily and accurately control the fuel flow, reduce delays in operation, and ensure that the equipment remains stable and efficient during long-term operation. The chamfered design further improves the reliability and smoothness of the equipment, ensuring the continuous and efficient regulation of fuel flow.

[0020] A rotating rod is installed at the rear end of the U-shaped block, arc-shaped protrusions are provided at the upper and lower ends of the rotating rod, a cross bar is installed at the other end of the rotating rod, adjusting rods are installed at both ends of the cross bar, an adjusting block is installed at the other end of the adjusting rod, a rotating rod is installed between the other ends of the two adjusting blocks, and a sealing disk is installed on the rotating rod.

[0021] The position of the adjustment block can be easily adjusted as needed, thereby changing the angle of the rotating rod and the position of the sealing disc. This flexible adjustment capability allows for more precise control of the fuel flow and can adapt to different refueling needs. The connection between the rotating rod and the crossbar makes the mechanical transmission more stable. The arc-shaped bump can evenly distribute the force applied to the adjustment rod during rotation, avoiding stress concentration. This design reduces friction between components and reduces the failure rate. The design of the arc-shaped bump reduces the contact area with other components during rotation, reducing the friction coefficient. Reducing friction not only improves the smoothness of operation, but also extends the service life of mechanical components and reduces the frequency and cost of maintenance. The adjustment block and the sealing disc can instantly adapt to changes in fuel flow requirements. This rapid response capability makes the fuel dispenser more efficient in actual applications.

[0022] The beneficial effects of the present invention are as follows: 1. The flow of fuel in the fuel dispenser drives the impeller to rotate, and then adjusts the sealing disk through a complex linkage mechanism to control the size of the opening in the oil pipe, ensuring the accuracy of flow control, thereby reducing errors in fuel flow, improving the accuracy of refueling, and maintaining a stable flow output of fuel at different flow rates without the need for complex manual intervention, thereby improving the degree of automation and convenience of the refueling process.

[0023] 2. The rotating column adopts a T-shaped cross-section design, which can effectively increase the stability of the rotating column, allowing it to rotate more smoothly under the drive of the impeller; and the T-shaped structure provides a larger force-bearing area and stronger support, which helps to extend the service life of the rotating column and the overall device and reduce mechanical wear.

[0024] 3. The counterclockwise return force generated by the spring can promptly pull the rotating column and related components back to the designed initial position when the fuel flow stops, avoiding damage to the components or inaccurate operation caused by continued rotation due to inertia or external force. The counterclockwise rotation and reset function of the spring effectively prevents the components from deviating from the predetermined position due to inertia during operation.

[0025] 4. The rotating slider adopts a T-shaped cross-section design, which can effectively reduce the friction when rotating between the U-shaped blocks. The T-shaped structure is characterized by less contact surface, which can reduce friction resistance during rotation and make the rotation smoother. The four corners of the rotating slider are designed as chamfers, which helps to avoid sharp friction or jamming between the edges and other parts during rotation. This not only improves the smoothness of the movement of mechanical parts, but also avoids damage or wear caused by sharp corners. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6 and 7, a high-precision flow control anti-cheating fuel dispenser 2 provided by the present invention includes a base 1, a fuel dispenser 2 and a baffle 3. The fuel dispenser 2 is installed on the upper end of the base 1, and the baffle 3 is installed above the fuel dispenser 2. The fuel dispenser 2 drives the impeller 243 to rotate through the flow of fuel, and the rotating impeller 243 drives the rotating column 244 to rotate. The rotation of the rotating column 244 drives the centrifugal rod 2453 to move outward, and the moving centrifugal rod 2453 drives the sliding block 245 to move vertically. The vertically moving sliding block 245 drives the rotating rod 248 to rotate by rotating the slider 2471, so that the rotating rotating rod 248 drives the sealing disk 2491 to rotate, so that the rotating sealing disk 2491 adjusts the flow rate of the fuel in the oil pipe 23.

[0031] The flow of fuel drives the impeller 243 to rotate, and then the sealing disk 2491 is adjusted through a complex linkage mechanism to control the size of the opening in the oil pipe 23. This precise mechanical transmission structure ensures the accuracy of flow control, thereby reducing the error in the flow of fuel and improving the accuracy of refueling. The automatic adjustment mechanism enables the fuel to maintain a stable flow output at different flow rates without complex manual intervention, thereby improving the automation and convenience of the refueling process; the present invention is based on pure mechanical principles and avoids complex electronic components, which not only reduces the maintenance cost and failure rate of the equipment, but also improves durability. Mechanical parts are easy to maintain and replace, and are particularly suitable for high-frequency use scenarios such as gas stations. The fuel dispenser 2 is equipped with a heating device to ensure that the internal fuel will not freeze in cold areas. The heating system maintains the fluidity of the fuel and can work normally even in a low temperature environment, improving the environmental adaptability and reliability of the equipment. In addition, the automatic resetting of the centrifugal rod 2453 is achieved through the clockwork 2444 device. When the fuel stops flowing, the clockwork 2444 mechanism will restore the device to its initial position to prepare for the next refueling. The automatic reset function ensures the stability and consistency of the refueling process, thereby improving the reliability of the refueling machine 2 under long-term operation and is suitable for high-frequency usage scenarios.

[0032] like Figure 2 , 3 As shown in Figure 4, the fuel dispenser 2 includes a fuel tank 21, a display panel 22, a fuel pipe 23, a control ring 24 and a fuel gun 25. The fuel tank 21 is installed on the upper end of the base 1, and the display panel 22 is installed on the side of the fuel tank 21. The fuel pipe 23 is installed at both ends of the fuel tank 21, and the control ring 24 is installed inside the fuel pipe 23. A fixed pipe 241 is installed in the inner array of the control ring 24, and a fixed cylinder 242 is installed at the other end of the fixed pipe 241. An impeller 243 is rotatably installed on the upper end of the fixed cylinder 242, and a rotating column 244 is fixedly installed on the upper end of the impeller 243. The cross-sectional shape of the rotating column 244 is T-shaped, and a fuel gun 25 is installed at one end of the outer side of the fuel pipe 23.

[0033] By installing a control ring 24 inside the oil pipe 23 and combining structures such as a fixed pipe 241, a fixed cylinder 242 and a rotating impeller 243, precise control of the flow of fuel can be achieved. The impeller 243 rotates with the flow of fuel, driving mechanical structures such as a rotating column 244 to adjust the flow. Compared with the traditional fuel dispenser 2, this design can more efficiently adjust and control the flow rate of fuel, thereby improving the refueling efficiency. The rotating column 244 adopts a T-shaped cross-section design, which effectively enhances the stability of the rotating column 244, allowing it to rotate more smoothly under the drive of the impeller 243. The T-shaped structure provides a larger force-bearing area and stronger support, which helps to extend the service life of the rotating column 244 and the overall device and reduce mechanical wear. Through the linkage design of the control ring 24 and the impeller 243, the fuel can automatically adjust the flow rate when it flows, ensuring the smoothness and accuracy of the flow process. The outer side of the oil pipe 23 is directly connected to the refueling gun 25, forming an integrated design, reducing connectors and intermediate equipment, and improving the convenience of operation. At the same time, this design makes the refueling operation smoother, reduces the possible risk of leakage, and improves the overall aesthetics of the device. The arrangement of the fixed cylinder 242 and the fixed pipe 241 ensures the stability of the overall structure and enhances the durability of the device. In addition, the impeller 243 and the rotating column 244 are optimized and can adapt to different environmental conditions, including use in low-temperature environments.

[0034] like Figure 3 and 4 As shown, both ends of the side surface of the rotating column 244 are provided with opening grooves 2441 for rotating outward and limiting sliding. The cross-section of the opening groove 2441 is U-shaped. A fixing column 2442 for limiting rotation is installed on the opening groove 2441 .

[0035] The design of the U-shaped support groove 2441 effectively limits the sliding range of the centrifugal rod 2453, making its movement more controlled and preventing unnecessary sliding or shaking. In this way, the entire transmission mechanism can operate more smoothly, especially in the case of high-speed rotation or severe vibration, thereby ensuring the stability and operation accuracy of the mechanical structure. At the same time, the limitation of the support groove 2441 reduces the excessive friction and wear generated during the rotation process, helps to extend the service life of the rotating column 244 and related mechanical components, and reduces the maintenance cost of the equipment, especially in the case of long-term high-frequency use, and has significant durability advantages; the U-shaped support groove 2441 provides a precise track for the rotating column 244, so that it rotates within a fixed range and maintains a stable direction. By limiting the angle and range of rotation by the fixed column 2442, the deviation during the rotation process can be effectively prevented, thereby improving the rotation accuracy of the entire mechanical device, ensuring the precise control of the opening of the oil pipe 23 and the accurate regulation of the fuel flow. In addition, the structure of the U-shaped support groove 2441 is relatively simple, which is convenient for adjustment and maintenance.

[0036] like Figure 4 , 5 As shown in FIG6 , both ends of the fixing column 2442 are provided with limiting rings 2443 , and a mainspring 2444 is installed inside the limiting ring 2443 , and the mainspring 2444 rotates counterclockwise.

[0037] When the fuel dispenser 2 stops working or the fuel flow stops, the spring 2444 restores the centrifugal rod 2453 to its initial position through its elastic action. This automatic reset function ensures that the device can remain in the initial state after each operation, ready for the next refueling, and improves the working efficiency and ease of operation of the device. The counterclockwise return force generated by the spring 2444 can promptly pull the rotating column 244 and related components back to the designed initial position when the fuel flow stops, avoiding damage to the components due to continued rotation due to inertia or external force or causing inaccurate operation. The counterclockwise rotation and reset function of the spring 2444 effectively prevents the components from deviating from the predetermined position due to inertia during operation. By keeping each component within the set range of motion, wear between parts is reduced, thereby extending the service life of the equipment. In addition, the automatic reset function reduces the intervention of operators and improves the stability of the equipment.

[0038] like Figure 4 , 5 As shown in FIG6 , a sliding block 245 is installed on the rotating column 244 , and the cross-sectional shape of the sliding block 245 is H-shaped. An extrusion block 2451 for downward extrusion is installed at the lower end of the sliding block 245 , and the cross-sectional shape of the extrusion block 2451 is T-shaped.

[0039] The cross section of the H-shaped sliding block 245 provides a larger contact surface and good guiding performance. Compared with other shapes, the H-shaped sliding block 245 is more stable during movement, reducing the jamming and irregular sliding caused by friction or offset. This ensures that the sliding block 245 remains stable during longitudinal movement, avoids errors, and thus improves the accuracy and reliability of the equipment. The combined design of the H-shaped sliding block 245 and the T-shaped extrusion block 2451 can evenly distribute the force. Driven by the rotating column 244, the sliding block 245 and the extrusion block 2451 will not experience stress concentration when subjected to force, avoiding local wear or deformation and extending the service life of the equipment components. The T-shaped cross-sectional design of the extrusion block 2451 makes it more efficient in transmitting the extrusion force, provides a larger force-bearing area, and can better transmit the movement force of the sliding block 245 to other components, thereby achieving precise regulation of the flow of the oil pipe 23. The H-shaped sliding block 245 is tightly combined with the rotating column 244, and the H-shaped cross-sectional design prevents the sliding block 245 from offsetting during movement. The sliding block 245 is limited by the guide groove when moving up and down, and is not easy to shake left and right, which enhances the accuracy of movement. At the same time, the T-shaped extrusion block 2451 provides good directional control when applying the extrusion force, avoiding rotation instability during operation. Through the mutual cooperation of the H-shaped sliding block 245 and the T-shaped extrusion block 2451, the power transmission process is smoother, ensuring that the movement of the rotating column 244 can be efficiently converted into the control of the fuel flow in the oil pipe 23.

[0040] like Figure 3 , 4 , 5, 6 and 7, L-connecting rods 2452 are installed at both ends of the T-shaped extrusion block 2451, one end of the centrifugal rod 2453 is installed on the L-connecting rod 2452, the other end of the centrifugal rod 2453 has a spherical structure, and the material of the centrifugal rod 2453 is made of polyvinyl chloride, the centrifugal rod 2453 is installed on the fixed column 2442, and the outer end of the spring 2444 is installed inside the centrifugal rod 2453, a heating box 246 is installed on the outer side of the control ring 24, and a heating tube 2461 is connected to one end of the heating box 246 close to the control ring 24, the heating tube 2461 passes through the fixed tube 241, the impeller 243 and the sliding block 245, and the heating tube 2461 is located in the rotating column 244.

[0041] The connection between the centrifugal rod 2453 and the L-link 2452 enables the centrifugal force to generate mechanical force through rotation, thereby driving the vertical movement of the sliding block 245. This control method based on mechanical linkage ensures the accuracy of flow regulation and avoids the uncertainty caused by complex electronic control systems. The centrifugal rod 2453 is made of polyvinyl chloride (PVC) material, which has the characteristics of light weight, excellent corrosion resistance and anti-static properties. Polyvinyl chloride can maintain good chemical stability when facing chemical substances such as fuel, and is not prone to corrosion or wear, thereby greatly improving the durability of the equipment. In addition, the lightweight characteristics of PVC material reduce the load during rotation. A heating box 246 is installed on the outside of the control ring 24, and the fuel is heated by the heating pipe 2461 to ensure that the fuel dispenser 2 can still work normally in low temperature or cold environment. The heating pipe 2461 runs through the fixed pipe 241, the impeller 243 and the sliding block 245, and is located in the rotating column 244, so that the fuel heating process is efficient and uniform. The fuel is kept within the appropriate temperature range, which reduces flow resistance and improves fluidity, thereby making the flow rate during refueling more stable, reducing refueling time and improving overall refueling efficiency, which is particularly suitable for applications in cold regions.

[0042] like Figure 7 As shown, a U-shaped block 247 is installed on the periphery of the sliding block 245, and a rotating slider 2471 is rotatably installed between the U-shaped blocks 247. The cross-section of the rotating slider 2471 is T-shaped, and the four corners of the upper end of the rotating slider 2471 are chamfered.

[0043] The peripheral design of the U-shaped block 247 provides additional support to ensure that the sliding block 245 and the rotating slider 2471 are more stable during operation. The tight fit between the U-shaped blocks 247 effectively prevents the loosening or displacement of the sliding block 245, and enhances the mechanical reliability of the overall structure. The rotating slider 2471 adopts a T-shaped cross-section design, which can effectively reduce the friction when rotating between the U-shaped blocks 247. The T-shaped structure is characterized by a small contact surface, which can reduce friction resistance during rotation and make the rotation smoother. The four corners of the rotating slider 2471 are designed as chamfers, which helps to avoid sharp friction or jamming between the edges and other parts during rotation. The chamfer design makes the edge of the slider more rounded, which not only improves the smoothness of the movement of the mechanical parts, but also avoids damage or wear caused by sharp corners. This helps to reduce maintenance requirements and extend the service life of the equipment. The combined design of the U-shaped block 247 and the T-shaped rotating slider 2471 ensures that the slider can move smoothly within the preset track when subjected to force, greatly improving the precise control ability of the mechanical system. This structure provides higher precision for the flow regulation of the oil pipe 23, avoiding flow control errors caused by misalignment of mechanical parts or excessive friction. By reducing friction and improving the smoothness of sliding, the combination of the U-shaped block 247 and the T-shaped slide block improves the operating efficiency of the entire fuel dispenser 2.

[0044] like Figure 5 and 7 As shown, a rotating rod 248 is installed at the rear end of the U-shaped block 247, and arc-shaped protrusions are provided at the upper and lower ends of the rotating rod 248. A cross bar 2481 is installed at the other end of the rotating rod 248, and adjusting rods 2482 are installed at both ends of the cross bar 2481. An adjusting block 2483 is installed at the other end of the adjusting rod 2482, and a rotating rod 249 is installed between the other ends of the two adjusting blocks 2483. A sealing disk 2491 is installed on the rotating rod 249.

[0045] As needed, the position of the adjustment block 2483 can be easily adjusted to change the angle of the rotating rod 249 and the position of the sealing disk 2491. This flexible adjustment capability makes the control of the fuel flow more precise and can adapt to different refueling needs. The connection method between the rotating rod 248 and the cross bar 2481 enhances the stability of mechanical transmission. The arc-shaped protrusion can evenly distribute the force applied to the adjustment rod 2482 during the rotation process, avoiding stress concentration. This design reduces the friction between components and reduces the failure rate. The design of the arc-shaped protrusion reduces the contact area with other components during rotation, thereby reducing the friction coefficient. Reducing friction not only improves the smoothness of operation, but also extends the service life of mechanical components and reduces the maintenance frequency and cost. The adjustment block 2483 and the sealing disk 2491 can quickly adapt to changes in fuel flow requirements. This rapid response capability makes the fuel dispenser 2 more efficient in actual applications.

[0046] During operation of the present invention, when the fuel in the fuel tank 21 flows, the flowing fuel drives the impeller 243 to rotate, and the rotating impeller 243 drives the rotating column 244 to rotate. The rotating rotating column 244 drives the centrifugal rod 2453 to generate centrifugal force, and then the centrifugal rod 2453 rotates outward under the action of the upper end ball. While the centrifugal rod 2453 is being moved outward, it will pull the L-link 2452 to move vertically under the restriction of the fixed column 2442. The vertically moving L-link 2452 drives the extrusion block 2451 and the sliding block 245 to move vertically. The vertically moving extrusion block 2451 and the sliding block 245 The block drives the rotating rod 248 to rotate by rotating the slider 2471, and the rotating rotating rod 248 drives the cross bar 2481 to move vertically, and the vertically moving cross bar 2481 drives the adjusting rod 2482 and the adjusting block 2483 to move vertically, so that the moving adjusting block 2483 drives the rotating rod 249 to rotate, and the rotating rotating rod 249 drives the sealing disk 2491 to rotate, so as to adjust the opening size of the oil pipe 23, and then control the flow of fuel; and the internal fuel can be heated by the heating box 246 and the heating pipe 2461 to prevent the fuel inside the fuel dispenser 2 from freezing and being unable to flow in cold areas.

[0047] When the fuel does not flow, the centrifugal rod 2453 is restored to its original position by the action of the spring 2444, so that the sealing disk 2491 can always be in the same position in the oil pipe 23, which facilitates more stable flow of the fuel and prepares for the next flow of the fuel.

[0048] Although the present disclosure has been described in detail above with general descriptions and specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements may be made based on the embodiments of the present disclosure. Therefore, these modifications or improvements made without departing from the spirit of the present disclosure are within the scope of protection claimed by the present disclosure.
