Those skilled in the art can make similar extensions 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] In order to make the purpose, technical solution and advantages of the utility model clearer, the implementation method of the utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please refer to Figure 1-2 As shown, this embodiment is an external pump electrostatic conduction mechanism, including:

[0024] An electrostatic conduction part, which includes a first conductive filter element 21, a second conductive filter element 22, and an electrostatic derivation spring 23. The second conductive filter element 22 is arranged and connected to the outside of the first conductive filter element 21, and the electrostatic derivation spring 23 is arranged and connected to the middle of one end of the second conductive filter element 22;

[0025] The first conductive filter element 21 and the second conductive filter element 22 are used to guide the static electricity on the fuel pump. The static electricity can be conducted out by using the static electricity guide spring 23 to reduce the probability of fire in the fuel pump;

[0026] The electrostatic conduction part is built-in and connected in the fuel pump part, and the fuel pump part includes a metal shell 11, a pump core 12, and a filter cover 13. The pump core 12 is fixedly connected to the middle part of the metal shell 11, and the filter cover 13 is threadedly connected to one end of the outer surface of the metal shell 11. One side of the outer surface of the pump core 12 is in contact with the inner side of the first conductive filter element 21;

[0027] The metal shell 11 is the main installation carrier of the fuel pump part and provides external protection. The pump core 12 is the main working element of the fuel pump part and performs structural installation on the first conductive filter element. The filter cover 13 is used to keep the pump core 12 inside the metal shell 11 to ensure the cleanliness and normal operation of the fuel system;

[0028] The ends of the second conductive filter element 22 are respectively attached to one end of the outer surface of the pump core 12 and the static electricity lead-out spring 23;

[0029] A protrusion is provided in the middle of one end of the pump core 12, and extends out of one end of the second conductive filter core 22, and the inner wall of the static electricity lead-out spring 23 is sleeved and fixed with the outer wall of the protrusion;

[0030] A groove is provided in the middle of one end of the filter cover 13, and one end of the inner wall of the groove contacts one end of the electrostatic lead-out spring 23;

[0031] The protrusion electrically contacts one end of the electrostatic lead-out spring 23, and electrically contacts the other end of the electrostatic lead-out spring 23 through contact with the inner wall of the groove. At the same time, the force formed by the contact acts on the second conductive filter element 22, which can limit the overall electrostatic conduction part to a secondary structure, ensure the stability of the structure, always fit the outer surface of the pump core 12, and improve the electrostatic conduction effect;

[0032] Working principle: During the use of the fuel pump, the first conductive filter element 21 is adhesively connected to the outer surface of the pump core 12, and the second conductive filter element 22 is adhesively connected to the outer surface of the first conductive filter element 21. One end of the second conductive filter element 22 is also in contact with the pump core 12, and the other end is in contact with the static electricity conducting spring 23. After guiding the static electricity through the first conductive filter element 21 and the second conductive filter element 22, it is conducted out through the static electricity conducting spring 23;

[0033] This solution can meet the requirement of static electricity removal to ensure the safety of fuel pump use. With the internal structure setting, it can avoid occupying external space. It has a simple structure, is convenient to install, and saves costs. At the same time, after the static electricity conducting spring 23 conducts the static electricity, through the formed repulsive force, it further ensures the stability of the static electricity conducting part structure, making it always in contact with the pump core 12 and improving the static electricity conduction effect.
