[0020] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the drawings.
[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0022] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model in conjunction with the accompanying drawings.
[0023] Please refer to Figures 1-3 As shown, this embodiment is an electrostatic conduction device, including:
[0024] An electrostatic conduction part, which includes a conductive filter 21, a conductive corrugated pipe 22, a conductive nozzle 23, and a conductive elastic sheet 24. The lower end of the conductive corrugated pipe 22 is fixedly connected to one side of the upper end of the conductive filter 21, and the conductive nozzle 23 is sleeved and connected to the upper end of the conductive corrugated pipe 22. The conductive elastic sheet 24 is arranged and connected to one side of the upper part of the conductive corrugated pipe 22;
[0025] While the conductive filter 21 satisfies conductivity, it also serves as a filtering structure for the oil fluid. In conjunction with the conductive corrugated pipe 22 and the conductive nozzle 23, it can not only satisfy conductivity but also be used for the transportation of the oil fluid. Moreover, by utilizing the telescopic characteristics of the conductive corrugated pipe 22, the adjustment of the usage length can be satisfied, improving the usage effect. The conductive elastic sheet 24 is also used for electrostatic conduction;
[0026] The electrostatic conduction part is arranged and connected inside the fuel pump part, and the fuel pump part includes a metal shell 11, a pump core 12, and an upper cover 13. The pump core 12 is fixedly connected to the middle part inside the metal shell 11, and the upper cover 13 is snap-connected to the upper end of the metal shell 11;
[0027] The metal shell 11 is the main installation carrier of the fuel pump part and provides external protection ability. The pump core 12 is the main working component of the fuel pump part, and the upper cover 13 seals and protects the upper part of the metal shell 11;
[0028] One side of the upper end of the upper cover 13 is provided with a through-hole, and the conductive nozzle 23 passes through the through-hole. One side of the middle part of the bottom end of the upper cover 13 is fixedly connected to the upper end of the conductive elastic sheet 24;
[0029] The through-hole is used for the conductive nozzle 23 to pass through to satisfy the normal extraction of the oil fluid;
[0030] It further includes an auxiliary disassembly part, which includes a movable tube 31, a support rod 32, and a movable spring 33. The movable tube 31 is symmetrically and fixedly connected to the end of one side inside the metal shell 11, and the support rod 32 is fixedly connected inside the movable tube 31. The movable spring 33 is sleeved on the outer surface of the upper part of the support rod 32;
[0031] The lower end of the movable spring 33 abuts against the upper end of the movable tube 31, and the upper end of the movable spring 33 abuts against one side of the bottom end of the upper cover 13;
[0032] The movable tube 31 is used to install the support rod 32 and to receive and fix the movable spring 33. Through the interference between the end of the movable spring 33 and the upper cover 13 and the movable tube 31, after the upper cover 13 is opened, it is convenient for the movable spring 33 to restore the reverse force exerted by the deformation, so that the upper cover 13 can be opened conveniently and labor-savingly, which is conducive to the inspection and replacement of the components inside the metal shell 11.
[0033] Working principle: During the use of the fuel pump, the conductive filter 21 is used to filter impurities in the oil, and the oil is discharged through the conductive bellows 22 in conjunction with the conductive oil nozzle 23;
[0034] During use, the conductive filter 21, the conductive bellows 22, the conductive nozzle 23, and the conductive spring 24 all have the function of conducting electricity, and can remove static electricity. At the same time, during the installation of the conductive nozzle 23, the length of the conductive nozzle 23 can be finely adjusted by utilizing the telescopic characteristics of the conductive bellows 22.
[0035] When the upper cover 13 is opened and the components inside the metal housing 11 are inspected, an upward force is applied to the upper cover 13, which is conducive to the movable spring 33 to restore the deformation and apply a reverse force to assist in applying the cover-opening force;
[0036] This solution utilizes the principle of self-static elimination to achieve the purpose of removing static electricity. There is no need to install a negative power connection line, which can reduce the occupation of the internal space of the metal shell 11 and can be opened quickly and conveniently, saving time and effort and improving the maintenance efficiency of components.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
