DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Example: Reference Figure 1-Figure 6 The oil filter comprises a housing 1, a transmitter 2 fixedly mounted on the top of the housing 1, the transmitter 2 being electrically connected to the warning light in the vehicle, and a base 3 fixedly mounted on the bottom of the housing 1, and further comprising:

[0027] In order to prevent frequent filter replacement, an early warning component is provided on the equipment, including a sealing plate 7 slidably mounted inside the housing 1, a sealing ring is provided on the outer edge of the sealing plate 7 to prevent oil leakage, and a trigger rod 6 is fixedly mounted on the sealing plate 7 at the center position, and the function of the trigger rod 6 is to resist and open the transmission when the sealing plate 7 approaches the conveyor 2. An oil pipeline 8 is fixedly mounted on the side of the sealing plate 7 away from the trigger rod 6, and a plurality of second oil inlets 9 are provided on one side of the oil pipeline 8. When the first filter element 12 is blocked, the oil pushes the sealing plate 7 upward, and during the pushing process, the second oil inlet 9 provided on the oil pipeline 8 is drawn out from the second filter element 17, and the oil enters the second filter element 17 from the second oil inlet 9. A fixing plate 11 is installed around the outer wall of the other side of the oil pipeline 8, and a spring 10 is fixedly mounted on one side of the fixing plate 11, which can tighten the sealing plate 7 when the filter is working normally, and play a sealing role on the second filter element 17. It is worth noting that the thrust of the spring 10 is smaller than the impact force of the oil when the first filter element 12 is about to be blocked.

[0028] refer to Figure 5A second filter element 17 is provided in the housing 1, and a spring 10 is fixedly connected between the fixing plate 11 and the second filter element 17. The spring 10 can limit the sealing plate 7, and the oil delivery pipe 8 is slidably arranged in the second filter element 17. A filter tube 13 is provided on the outer wall of the second filter element 17, and a third cavity 22 is provided in the filter tube 13. A plurality of oil filter holes 14 are provided on both outer walls of the filter tube 13, and a one-way valve 15 rotating toward the third cavity 22 is provided on the oil filter holes 14 on both sides. The oil filtered by the first filter element 12 enters the third cavity 22 through the one-way valve 15 on the side of the first filter element 12, and the oil filtered by the second filter element 17 enters the third cavity 22 through the one-way valve 15 on the side of the second filter element 17. The one-way valves 15 on both sides rotate relatively and cannot flow back to another filter element in series.

[0029] refer to Figure 2 and Figure 4 A plurality of first oil inlets 4 are provided on the base 3, so that the engine oil can enter the first cavity 16 from the plurality of first oil inlets 4 at the same time. A hollow plate 19 is fixedly installed on the side of the base 3 close to the second filter element 17. The hollow plate 19 can prevent the unfiltered engine oil from entering the filter element. A second cavity 20 is provided in the hollow plate 19. A plurality of second oil outlets 18 are provided on the side of the hollow plate 19 close to the filter tube 13, and the second oil outlet 18 is located between the third cavity 22 of the filter tube 13. The engine oil first enters the interior of the filter from the first oil inlet 4 provided on the base 3. Due to the setting of the hollow plate 19, the engine oil can only enter the inner cavity from the first oil inlet 4.

[0030] It is worth noting that a first oil outlet 5 is provided at the center of the third cavity 22 , and a threaded groove 21 is provided on the inner wall of the first oil outlet 5 , which can be threadedly connected to an external oil pipeline.

[0031] A first filter element 12 is provided around the outer wall of the reference filter tube 13, and the engine oil can enter the filter tube 13 from the first filter element 12 for filtration. The first filter element 12 is fixedly connected to the base 3, and a first cavity 16 is provided between the first filter element 12 and the inner wall of the shell 1. The first cavity 16 is located directly above the first oil inlet 4, and the engine oil enters the first cavity 16 from the first oil inlet 4.

[0032] By adopting the above technical solution, when the first filter element 12 is blocked, the engine oil enters the first cavity 16 through the first oil inlet 4, and then enters the third cavity 22 opened in the filter tube 13 after passing through the first filter element 12. Due to the action of the one-way valve 15, the engine oil cannot enter the second filter element 17 at this time, and finally the engine oil flows out of the first oil outlet 5 from the second oil outlet 18 provided below the third cavity 22.

[0033] When the first filter element 12 is clogged, the engine oil pushes against the sealing plate 7 and moves upward. During the movement of the sealing plate 7, a second oil inlet 9 is opened on the oil pipe 8 and flows out from the second filter element 17. The engine oil enters the second filter element 17 from the second oil inlet 9. The engine oil is filtered from the second filter element 17 into the third cavity 22, and then flows out of the first oil outlet 5 from the second oil outlet 18 provided below the third cavity 22.

[0034] At the same time, when the sealing plate 7 moves upward, the trigger rod 6 contacts the transmitter 2, and the transmitter 2 sends a prompt to the vehicle that the first filter element 12 is blocked. It is worth noting that when the second filter element 17 is started after the first filter element 12 is blocked, the filter can only be used for 1,000 kilometers. The time to replace the filter is determined based on the mileage of the user's vehicle.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
