Description

Technical Field

[0001] This utility model relates to the technical field of fuel tank draining mechanism, and in particular to fuel tank draining and cleaning mechanism and vehicle. Background Technology

[0002] Currently, most domestic and international electronic fuel injection tanks use built-in fuel pumps and galvanized sheets. The manufacturing process involves drawing and welding, which generates iron powder and welding residue during the punching and welding processes. During painting, the tank uses inner galvanized sheet material and undergoes a spraying process before pretreatment. These multiple processes can lead to a significant accumulation of dust inside. Even if cleaning is performed during the process, this increases the probability of problems during the later use of the vehicle and maintenance of the fuel system. Traditional iron magnetized screws are magnetic, causing iron powder to be attracted to the threads. This makes assembly difficult when directly locking the threads to the drain plug bolt, and the threads may eventually break down, leading to serious seal failure. This application addresses the above-mentioned defects. Utility Model Content

[0003] The purpose of this invention is to provide a fuel tank draining and cleaning mechanism and vehicle that can collect iron powder in the fuel tank, thus solving the problems of increased vehicle failure rate and traditional magnetized screw seal failure caused by dust in the fuel tank due to previous steps.

[0004] To address the aforementioned problems, this utility model provides an oil tank draining and cleaning mechanism, comprising a magnetic part, a bolt assembly, a drain port stud, and a nut. The bolt assembly can be connected to the nut, and the drain port stud is located on the periphery of the connection point between the bolt assembly and the nut. The magnetic part is located at one end of the bolt assembly near the oil tank. Separating the nut and the bolt assembly allows for oil draining. The magnetic part at the end can attract internal iron powder, thus draining excess impurities while simultaneously attracting iron impurities, maximizing the cleanliness of the oil tank and extending the service life of the oil pump. Furthermore, since only the end is magnetic, it reduces the impact on the surrounding environment or other equipment, providing anti-interference capabilities and preventing iron powder from adsorbing onto the threads of the bolt assembly.

[0005] According to one embodiment of the present invention, the magnetic part is part of the bolt assembly, that is, the head end of the bolt assembly is directly set with magnetic material or magnetized.

[0006] According to one embodiment of the present invention, the magnetic part is a separate component that is mounted on a bolt assembly, which is simple to assemble and has a low cost.

[0007] According to one embodiment of the present invention, the bolt assembly is made of a non-magnetic material, such as brass. When the bolt assembly and the magnetic part are integrally formed, the bolt assembly is made of a non-magnetic material except for the magnetic part.

[0008] According to one embodiment of the present invention, the magnetic part is a magnet, but other magnetic materials may also be used.

[0009] According to one embodiment of the present invention, the bolt assembly has a groove at its end for mounting a magnetic part.

[0010] According to one embodiment of the present invention, the magnetic part is encapsulated in the groove with epoxy resin, resulting in superior and more reliable sealing.

[0011] According to one embodiment of the present invention, a sealing ring is provided between the nut and the drain plug stud.

[0012] According to one embodiment of the present invention, the nut is provided with a receiving groove for accommodating the sealing ring.

[0013] A vehicle, including a motorcycle or other vehicle with a fuel tank, includes the aforementioned fuel tank draining and cleaning mechanism, which is installed on the fuel tank component of the fuel system.

[0014] The beneficial effects of this utility model are that by setting a magnetic part, iron powder inside the oil tank can be adsorbed. While draining oil and cleaning to release excess impurities, it can also adsorb iron impurities, thus maximizing the protection of the cleanliness inside the oil tank and the service life of the oil pump. Furthermore, since only the end is magnetic, it can reduce the impact on the surrounding environment or other equipment, play an anti-interference role, and also prevent iron powder from adsorbing at the threads of the bolt assembly, ensuring its service life.

[0020] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0021] Fuel tank draining and cleaning mechanism, such as Figures 1-3 It includes a magnetic part 11, a bolt assembly 12, an oil drain stud 13, a nut 14, and a sealing ring 15.

[0022] The bolt assembly 12 is made of brass and has a threaded part 121 and a groove 122 at the end. The magnetic part 11 is a magnet and is encapsulated in the groove 122 with epoxy resin for a more reliable seal. The magnetic part 11 is used to adsorb iron powder inside the oil tank 2.

[0023] The end of the drain plug stud 13 is provided with a stepped part 131 for positioning when installed on the oil tank 2.

[0024] The nut 14 has a positioning end face 143, a threaded hole portion 142 connected to the bolt assembly 12, and a receiving groove 141 for accommodating the sealing ring 15. The bolt assembly 12 can be connected to the nut 14. The threaded connection method is convenient for maintenance. The drain plug stud 13 is located on the periphery of the connection position between the bolt assembly 12 and the nut 14. The positioning end face 143 is used to position the relative position of the bolt assembly 12 and the drain plug stud 13.

[0025] Separate the nut 14 from the drain plug stud 13, and use the gap between the bolt assembly 12 and the drain plug stud 13 to perform the oil draining operation. The magnetic part 11 at the end can attract internal iron powder. While draining oil and cleaning, it can also attract iron impurities, thus maximizing the cleanliness of the oil tank and the service life of the oil pump. Since only the end is magnetic, it can reduce the impact on the surrounding environment or other equipment, play an anti-interference role, and also prevent iron powder from being attracted to the threads of the bolt assembly 12.

[0026] In this design, the magnet 11 and the copper bolt assembly 12 are encapsulated with epoxy resin to form a magnetic bolt mechanism, rather than an iron magnetized screw. Because the motorcycle has a compact layout and electronic control components are concentrated at the bottom of the fuel tank, this combination structure can reduce the impact on the surrounding environment or other equipment and play an anti-interference role. Secondly, the oil drain port stud 13 of the fuel tank drain cleaning mechanism is brazed to the fuel tank drain port, rather than being directly locked with a magnetized screw, making the mechanism more reliable and durable.

[0027] A sealing groove is added to the oil drain stud 13 for fitting a sealing ring 15. A sealing ring 15 is provided between the nut 14 and the oil drain stud 13, making the sealing performance better and more reliable.

[0028] A vehicle, such as a motorcycle or other vehicle with a fuel tank, includes the aforementioned fuel tank draining and cleaning mechanism, such as... Figure 4 The fuel tank draining and cleaning mechanism 1 is installed on the fuel tank 2 in the fuel system.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
