Description

Technical Field

[0001] The utility model relates to the field of oil filters, in particular to an oil filter with a visible filter element. Background Art

[0002] In order to solve the problem that diesel engines are generally difficult to start in low temperature environments and vehicles parked for a long time, there is currently a filter assembly, commonly known as the fuel water cold treasure, which includes an electric pump, a filter element and a heater. When the ambient temperature is low, the electric pump and the heater are started by the electronic controller, and the diesel is filtered by the filter element and provided to the engine for combustion and starting. Since it heats the diesel while pumping oil, it can improve the fluidity of the fuel, increase the temperature of the fuel, and ensure that the engine can start. However, it is currently found that the high-pressure oil pump and injector of the high-pressure common rail diesel engine with National III and National IV emissions are often damaged, causing huge losses to users. The reason is that since the existing filter assembly product has an iron filter element shell, the user cannot see the blockage of the internal filter element body, so the filter element cannot be replaced in time, causing damage to the equipment. Summary of the invention

[0003] In view of the deficiencies of the above background technology, the utility model provides an oil filter with a visible filter element.

[0010] Wherein, the sealing gasket is made of elastic material. When the sealing cover is assembled onto the port, the sealing cover presses the sealing gasket onto the upper surface of the upper sealing plate, and the oil inlet pipe passes through the notch and the opening and is connected to the oil guide pipe.

[0024] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0025] As attached Figure 1 , Figure 6 and Figure 7 As shown, an oil filter with a visible filter element comprises a filter housing 1 , a filter element 2 , a sealing gasket 3 and a sealing cover 4 .

[0026] As attached Figures 3 to 8 As shown, the internal space of the filter housing 1 is divided into a filter chamber 11 and an oil clean chamber 12, the upper cavity opening of the filter chamber 11 is open, and the filter element 2 is placed into the filter chamber 11 from the upper cavity opening of the filter chamber 11, wherein a filter channel 2a passes through the axis of the filter element 2, and the upper and lower surfaces of the filter element 2 are respectively sealed with an upper sealing plate 21 and a lower sealing plate 22, and the diameters of the upper sealing plate 21 and the lower sealing plate 22 are both larger than the diameter of the filter element 2, and an oil inlet pipe 24 passes through the upper sealing plate 21, and the oil inlet pipe 24 is connected to the filter channel 2a, and a cover 4 is sealed at the upper cavity opening of the filter chamber 11, and an opening 41 passes through the cover 4. When the cover 4 is assembled to the upper cavity opening of the filter cavity 11, the cover 4 presses and fixes the filter element 2 in the filter cavity 11. At this time, the oil inlet pipe 24 passes through the notch 31 and the opening 41 and is connected to the oil guide pipe 5. The surface of the filter housing 1 is provided with an oil outlet pipe 13, which is connected to the clean oil cavity 12, and the oil outlet pipe 13 is externally connected to the oil drain pipe 6. During filtering, the oil enters the filter channel 2a from the oil inlet pipe 24 through the oil guide pipe 5, and the oil in the filter channel 2a flows into the clean oil cavity 12 after being filtered by the filter element 2, and finally passes through the oil outlet pipe 13 and flows out from the oil drain pipe 6 for use. Among them, the filter housing 1 is made of transparent material, and the working state of the internal filter element 2 can be observed at a glance, and the blockage of the filter element 2 can be judged in time, so as to replace the filter element 2 in time to avoid damage to the equipment. At the same time, since the oil is filtered from the inside to the outside on the filter element 2, the filter element 2 is also gradually blocked from the inside to the outside when in use. Therefore, when the filter element 2 is observed to be blocked on the outside, the filter element 2 can be directly replaced, ensuring the filtering performance of the filter element 2 while ensuring the utilization rate of the filter element 2, reducing the filtering cost. Among them, the oil inlet pipe 24 is fixedly connected with the oil guide pipe 5 by thread matching, and the oil outlet pipe 41 is fixedly connected with the oil discharge pipe 6 by thread matching, which can be easily and quickly disassembled.

[0027] It is worth mentioning that Figures 4 to 7As shown, a sealing gasket 3 is provided on the upper surface of the upper sealing plate 21. The sealing gasket 3 is made of silicone material. Silicone is a high-quality material with many characteristics, such as good transparency, high elongation, strong tensile strength, high density, etc. The sealing gasket 3 made of silicone as the main raw material also has the high-quality characteristics of silicone, so that the sealing gasket 3 has good chemical stability, high temperature resistance, low temperature resistance, oxidation resistance, ozone resistance, good air permeability, water resistance, oil resistance, and corrosion resistance. A notch 31 runs through the axis of the sealing gasket 3, and the notch 31 corresponds to the opening 41. When the cover 4 is assembled to the upper cavity opening of the filter cavity 11, the cover 4 presses the filter element 2 to fix it in the filter cavity 11, and the cover 4 presses the sealing gasket 3 on the upper surface of the upper sealing plate 21, and uses the sealing gasket 3 to seal the gap between the upper sealing plate 21 and the opening 42 of the cover 4 to prevent oil leakage.

[0028] In addition, as attached Figure 2 , Figure 6 and Figure 7 As shown, the filter element 2 is detachably placed in the filter chamber 11. Specifically, the cover 4 is detachably arranged at the upper cavity opening of the filter chamber 11, wherein the upper cavity opening of the filter chamber 11 protrudes upward to form a port 1a, and the cover 4 is threadedly matched and fixedly connected with the port 1a. When in use, the cover 4 is screwed on the port 1a, and the filter element 2 is pressed and fixed in the filter chamber 11 by using the cover 4 and the sealing gasket 3 to prevent the filter element 2 from being skewed during use, resulting in a gap between the filter element 2 and the cover 4 and causing oil leakage. When the function of the filter element 2 is exhausted, it is only necessary to unscrew the cover 4 and the oil guide pipe 5 and replace the new filter element 2, without throwing away the entire oil filter, thereby reducing the cost. At the same time, a sealing ring can be set at the connection gap between the cover 4 and the port 1a. The sealing ring is made of the same material as the sealing gasket 3, which can play a good sealing role and prevent the oil in the filter housing 1 from leaking out.

[0029] In addition, if attached Figures 4 to 7 As shown, a positioning portion 23 is provided on the end surface of the upper sealing plate 21 and the lower sealing plate 22 facing away from the filter element 2, and a groove 32 is provided on the bottom of the filter cavity 11 and the bottom surface of the sealing gasket 3. The positioning portions 23 on the upper sealing plate 21 and the lower sealing plate 22 are respectively embedded in the filter cavity 11 and the groove 32 of the sealing gasket 3. The inner wall of the groove 32 restricts the outer wall of the positioning portion 23, thereby enhancing the connection stability of the filter element 2 in the filter cavity 11, and further preventing the filter element 2 from loosening and skewing during use.

[0030] In summary, when the utility model is in use, since the filter housing 1 is made of transparent material, the working state of the internal filter element 2 can be clearly observed, and the blockage of the filter element 2 can be judged in time, so as to replace the filter element 2 in time to avoid damage to the equipment. When the function of the filter element 2 is exhausted, it is only necessary to remove the cover 4 and the oil guide pipe 5 and replace the new filter element 2, without discarding the entire oil filter, thereby reducing costs.

[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
