Description

Technical Field

[0001] The utility model belongs to the technical field of fuel filter design, in particular to a fuel filter with a spin-on structure. Background Art

[0002] A fuel filter is a component used in automobiles or other internal combustion engine equipment. Its function is to filter impurities and contaminants in the fuel to ensure that the fuel entering the engine is clean and harmless. Fuel filters are usually installed in the fuel pipeline of the car to filter out water, sludge, dust and other foreign matter, effectively extending the service life of the engine and improving the combustion efficiency of the fuel.

[0003] When filtering impurities, part of the fuel will be retained on the filter screen. The remaining fuel is sticky and difficult to fall off, and it clumps with impurities to block the filter screen, which affects the service life of the device and also causes fuel waste. Utility Model Content

[0004] The utility model aims to provide a fuel filter with a spin-on structure to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A spin-on fuel filter comprises a shell device, wherein a filter device is arranged in the middle of the shell device; the filter device comprises a filter frame, wherein a plurality of limiting holes are evenly arranged on the circumference of the filter frame, a filter screen is arranged in the middle of the filter frame, and a plurality of magnetic blocks are evenly arranged on the circumference of the top of the filter frame.

[0007] Further: the shell device includes a lower shell, an upper shell is arranged on the top of the lower shell, connecting flanges are fixedly arranged on the top of the lower shell and the bottom of the upper shell, a plurality of sleeves are evenly fixedly arranged on the middle circumference of the lower shell, a plurality of sliding rods are evenly fixedly arranged on the middle circumference of the upper shell, a plurality of electromagnets are evenly installed on the top circumference of the upper shell, connecting pipes are evenly fixedly arranged on the bottom of the lower shell and the top of the upper shell, and connecting threads are arranged on the connecting pipes.

[0008] Furthermore, the slide rod is plug-in connected to the sleeve, and the filter frame is plug-in connected to the slide rod.

[0009] Furthermore: the connecting pipe is integrally formed with the lower shell and the upper shell respectively.

[0010] Furthermore: the filter screen is conical, and the filter frame is annular.

[0011] Furthermore: the magnetic blocks correspond one to one with the electromagnets.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Pass the slide bars through the limit holes on the filter frame respectively, and then close the upper shell and the lower shell together. Insert the slide bar into the sleeve to realize the limit connection between the lower shell and the upper shell. At this time, the bottom of the filter frame is supported by the sleeve. The height of the filter frame is determined, and the two connecting flanges are fixed by bolts. At this time, the installation between the lower shell and the upper shell is completed. By setting the design of the slide bar and the sleeve, the positioning accuracy between the lower shell and the upper shell is improved, the air tightness of the device is maintained, and it is convenient to quickly determine the position of the filter frame;

[0014] 2. When the filter is filtering, part of the fuel will be retained on the filter and clogged with impurities. Therefore, after the fuel passes through the device, the upper shell supporting electromagnet generates magnetism, attracts the magnetic block below, and drives the filter frame to rise along the slide bar. Then the electromagnet is powered off, and the filter frame falls naturally. The electromagnet is repeatedly opened and closed to achieve the up and down vibration of the filter, and the residual fuel is thrown out to prevent the filter mesh from being blocked, thereby increasing the service life of the device, reducing fuel waste and saving costs.

The limiting holes 202 on the filter frame 201 pass through the slide bars 105 respectively, and then the upper shell 102 and the lower shell 101 are closed together, and the slide bar 105 is inserted into the sleeve 104 to realize the limiting connection between the lower shell 101 and the upper shell 102. At this time, the bottom of the filter frame 201 is supported by the sleeve 104, and the height of the filter frame 201 is determined. The two connecting flanges 103 are fixed by bolts. At this time, the installation between the lower shell 101 and the upper shell 102 is completed. By setting the design of the slide bar 105 and the sleeve 104, the positioning accuracy between the lower shell 101 and the upper shell 102 is improved, the air tightness of the device is maintained, and it is convenient to quickly determine the position of the filter frame 201. The two connecting pipes 107 are connected to the fuel pipeline through the connecting threads 108 respectively to complete the overall installation of the device;

[0026] In this embodiment, the filter device 2 includes a filter frame 201, a plurality of limit holes 202 are evenly arranged on the circumference of the filter frame 201, a filter screen 203 is arranged in the middle of the filter frame 201, and a plurality of magnetic blocks 204 are evenly arranged on the circumference of the top of the filter frame 201. The filter screen 203 is conical, and the filter frame 201 is annular. The magnetic blocks 204 correspond to the electromagnets 106 one by one. When the fuel passes through the inside of the device, the filter frame 201 supports the filter screen 203 to filter the fuel to reduce the amount of impurities in the fuel. Since the fuel has a certain viscosity, the filter screen 203 03 During filtration, part of the fuel will be retained on the filter 203 and aggregate with impurities to block the filter 203. Therefore, after the fuel passes through the device, the upper shell 102 supports the electromagnet 106 to generate magnetism, attracting the magnetic block 204 below, driving the filter frame 201 to rise along the slide bar 105, and then the electromagnet 106 is powered off, and the filter frame 201 falls naturally.

[0027] Working principle: When in use, the limiting holes 202 on the filter frame 201 are respectively passed through the slide rod 105, and then the upper shell 102 and the lower shell 101 are closed together, and the slide rod 105 is inserted into the sleeve 104 to realize the limiting connection between the lower shell 101 and the upper shell 102. At this time, the bottom of the filter frame 201 is supported by the sleeve 104, and the height of the filter frame 201 is determined. The two connecting flanges 103 are fixed by bolts. At this time, the installation between the lower shell 101 and the upper shell 102 is completed. By setting the design of the slide rod 105 and the sleeve 104, the positioning accuracy between the lower shell 101 and the upper shell 102 is improved, the air tightness of the device is maintained, and it is convenient to quickly determine the position of the filter frame 201, and the two connecting pipes 107 are connected to the fuel through the connecting threads 108 The pipelines are connected to complete the overall installation of the device. When the fuel passes through the inside of the device, the filter frame 201 supports the filter screen 203 to filter the fuel and reduce the amount of impurities in the fuel. Since the fuel has a certain viscosity, part of the fuel will be retained on the filter screen 203 when the filter screen 203 is filtered, and the filter screen 203 is blocked by impurities. Therefore, after the fuel passes through the device, the upper shell 102 supports the electromagnet 106 to generate magnetism, attracting the magnetic block 204 below, driving the filter frame 201 to rise along the slide bar 105, and then the electromagnet 106 is powered off, and the filter frame 201 falls naturally. The electromagnet 106 is repeatedly opened and closed to achieve the up and down vibration of the filter screen 203, and the residual fuel is thrown out to prevent the mesh of the filter screen 203 from being blocked, thereby increasing the service life of the device, reducing fuel waste, and saving costs.
