Description

Technical Field

[0001] This utility model relates to the field of fuel pumps, and more specifically, to a compact fuel pump. Background Technology

[0002] Existing fuel pumps typically include a pump body, flow outlet, power cord, and power switch. In traditional designs, the power cord and power switch are usually located at the same end of the flow outlet, while the motor or power interface is located at the other end or rear of the pump body. This layout requires the power cord to travel from the flow outlet to the other end of the pump body to connect to the motor or power interface, increasing the cable length and making the overall structure less compact, resulting in inconvenient installation and maintenance.

[0003] Furthermore, the need for the power cord to be routed around the pump could affect its appearance and increase the risk of cable wear or accidental pulling, thus impacting the equipment's reliability and lifespan. This design could also complicate the production and assembly process, increasing manufacturing costs.

[0004] Therefore, it is necessary to optimize the structure of existing fuel pumps to solve the above problems. Utility Model Content

[0022] A compact fuel pump 1 includes a fuel pump 1, with a liquid outlet 2 at one end. A fuel nozzle 3 is detachably connected to the liquid outlet 2. The fuel pump 1 has a terminal block 4 near a power interface, and a control switch 6 is installed on the terminal block 4. A wire connecting the control switch 6 and the fuel pump 1 is installed inside the terminal block 4. By integrating the power terminal block 4 to the same side as the motor interface, the liquid outlet 2, the fuel pump 1, and the terminal block are connected in a straight line. This layout reduces the complexity of power wiring, and the compact structure improves space utilization and reduces external interference. Simultaneously, the same-side direct connection design makes installation and maintenance more convenient, allowing for quick wiring or maintenance without the need for winding. The reduced risk of wire bending and wear further enhances the safety and reliability of the equipment. Furthermore, the improved clean appearance and standardized interface not only enhance aesthetics but also enable modular design, achieving multiple improvements in cost, efficiency, and safety.
