Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a device for rapid venting of motorcycle fuel tanks. Background Technology

[0002] Currently, the bottom-mounted fuel tanks on two-wheeled motorcycles only allow gasoline to flow in and air to escape during refueling through a small opening in the internal hose of the fuel filler neck. However, when using a fuel nozzle, the nozzle may shut off before the tank is full, causing gasoline to splatter. This problem results in incomplete filling and gasoline splashing everywhere, staining clothing and posing a potential fire hazard. Utility Model Content

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0021] Please see Figures 1 to 3 The diagram illustrates a preferred embodiment of a motorcycle fuel tank rapid venting device, comprising a fuel tank 1, a filler pipe 2, a first conduit 3, a second conduit 4, and a fuel line 5. The filler pipe 2 is located at the upper end of the fuel tank 1. The first conduit 3 is located near the filler pipe 2 at the upper end of the fuel tank 1, with its lower end communicating with the interior of the fuel tank 1. The second conduit 4 is located on one side of the upper end of the filler pipe 2. Both ends of the fuel line 5 connect to the first conduit 3 and the second conduit 4. In this embodiment, see [reference needed]. Figure 1 As shown, the arrangement of the first conduit 3, the second conduit 4, and the fuel line 5 establishes an independent venting channel for the fuel tank 1, which does not interfere with the refueling line 2. When gasoline is added to the fuel tank 1, the air inside the fuel tank 1 is compressed by the fuel, enters the fuel line 5 through the first conduit 3, then flows into the refueling line 2 through the second conduit 4, and finally exits through the filling port of the refueling line 2. This venting channel is arranged along the side of the refueling line 2, forming a parallel and independent path with the refueling channel, ensuring that air can be discharged quickly and smoothly. This structure effectively solves the problem of poor air discharge during refueling using a traditional fuel tank 1. The independent venting channel eliminates the pressure difference inside the fuel tank 1, avoiding fuel splashing caused by pressure obstruction, reducing fuel waste and safety hazards. At the same time, rapid venting makes the refueling process smoother, shortens refueling time, and improves the user experience. In addition, the presence of the exhaust passage can indirectly reflect the amount of fuel in the fuel tank 1. When the fuel level rises to the point of blocking the lower end of the first conduit 3, the exhaust passage is blocked, and a noticeable "backflow" phenomenon will occur when refueling, indicating to the user that the fuel tank 1 is about to be filled, thereby achieving effective control of the amount of fuel added and avoiding fuel overflow.

[0022] Furthermore, as a preferred embodiment, the refueling pipe 2 includes a filling pipe 6 and a connecting pipe 7. The lower end of the connecting pipe 7 communicates with the interior of the fuel tank 1, and the upper end of the connecting pipe 7 is connected to the lower end of the filling pipe 6. One end of the second conduit 4 communicates with the interior of the filling pipe 6. The upper end of the filling pipe 6 is the filling port, and the fuel tank cap 8 is located at the upper end of the filling pipe 6 to seal the filling port. The fuel tank cap 8 is provided to seal the filling port when not refueling, preventing dust and impurities from entering the fuel tank 1 or fuel from evaporating.

[0023] Furthermore, as a preferred embodiment, the fuel tank 1 includes an upper fuel tank shell 9 and a lower fuel tank shell 10. The upper fuel tank shell 9 is disposed at the upper end of the lower fuel tank shell 10 and is sealed to it. A sealing ring can be provided between the upper fuel tank shell 9 and the lower fuel tank shell 10 to achieve a seal between them. The lower fuel tank shell 10 and the upper fuel tank shell 9 can be connected by bolts or welding. The upper end of the upper fuel tank shell 9 is provided with a fuel tank opening 11, and the lower end of the connecting pipe 7 is connected to the fuel tank opening 11 to ensure reliable sealing of the fuel filling channel. The first conduit 3 and the second conduit 4 are made of metal pipes, and a preset gap is reserved between the first conduit 3 and the filling pipe 2 to avoid friction or vibration interference caused by contact between the two. In this embodiment, the lower end of the connecting pipe 7 is welded to the fuel tank opening 11, and the filling pipe 6 and the connecting pipe 7 are welded and fixed together. The fuel tank cap 8 is threaded to the upper end of the filling pipe 6. An external thread is provided on the outer wall of the upper end of the filling pipe 6, and an internal thread that mates with the external thread is provided on the inner wall of the fuel tank cap 8. A sealing gasket that mates with the upper surface of the filling port is provided on the upper inner wall of the fuel tank cap 8.

[0024] In this embodiment, a through hole is provided at the upper end of the upper shell 9 of the oil tank for connecting with the first conduit 3, so that the first conduit 3 can communicate with the inside of the oil tank 1. The first conduit 3 is inserted into the through hole and welded to the upper shell 9 of the oil tank. The first conduit 3 can be welded to the oil pipe 5. The oil pipe 5 is made of metal and is welded to the second conduit 4. The second conduit 4 is welded to the filling pipe 6. The filling pipe 6 is provided with a connection hole for connecting with the second conduit 4. The second conduit 4 is inserted into the connection hole.

[0025] To use, open the fuel tank cap 8, insert the fuel nozzle into the filling pipe 6, and then add fuel. The fuel flows through the filling pipe 6 into the connecting pipe 7, and then into the fuel tank 1. Simultaneously, air in the fuel tank 1 enters the fuel line 5 through the first conduit 3, then through the second conduit 4 into the filling pipe 6, and is then expelled from the filling port, preventing fuel splashing. When "backflow" is observed during refueling, stop refueling. At this point, the fuel level in the fuel tank 1 is moderate, preventing overflow. After refueling, close the fuel tank cap 8 to ensure a tight seal.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
