Based on the embodiments in 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.

[0021] When the existing oil filter is used in winter, the temperature of the car is lower before driving, causing the oil inside the car to flow slower due to the lower temperature, which may affect the filtering effect of the oil filter and affect the service life of the engine over time.

[0022] In view of this, the utility model provides an automobile oil filter. Through the cooperation between the PTC heating plate, the conduit and the heat conducting plate, when the automobile is driving in winter, the PTC heating plate is started, the PTC heating plate will generate heat, and the generated heat is transferred to the heat conducting plate through the conduit, and the heat conducting plate then transfers the heat to the inside of the filter, so that the filter can gradually heat the oil while filtering it, avoiding the slow flow rate of the oil due to too low temperature, thereby affecting the filtering effect.

[0023] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0024] Embodiment 1: Figure 1-4 It can be seen that an automobile oil filter comprises a housing 1, the outer wall of the housing 1 is provided with a heating device, the heating device comprises a PTC heating plate 2, a conduit 3 and a heat conducting plate 4, the PTC heating plate 2 is fixedly connected to the outer wall of the housing 1, both sides of the PTC heating plate 2 are connected with the conduit 3, the other end of the conduit 3 is connected with the heat conducting plate 4, the bottom of the heat conducting plate 4 is fixedly connected to the outer wall of the housing 1, the PTC heating plate 2 is heated at a constant temperature, and the specific model is B-77*62;

[0025] In the specific implementation process, it is worth pointing out that when the car is driving in winter, the PTC heating plate 2 is started, and the PTC heating plate 2 generates heat, and the generated heat is transferred to the heat conducting plate 4 through the conduit 3, and the heat conducting plate 4 then transfers the heat to the inside of the filter, so that the filter can gradually heat the oil while filtering the oil, avoiding the slow flow rate of the oil due to too low temperature, thereby affecting the filtering effect;

[0026] Specifically, when the automobile oil filter is used, when the automobile is driving in winter, the PTC heating plate 2 is started, the PTC heating plate 2 generates heat, and the generated heat is transferred to the heat conducting plate 4 through the conduit 3, and the heat conducting plate 4 then transfers the heat to the inside of the filter, so that the filter can gradually heat the oil while filtering the oil, thereby avoiding the slow flow rate of the oil due to too low temperature, thereby affecting the filtering effect.

[0027] Embodiment 2: By Figure 1-4 It can be seen that a spring 6 is fixedly connected to the bottom of the inner wall of the housing 1, a first cover plate 7 is fixedly connected to the top of the spring 6, and a bypass valve 18 is installed on the top of the first cover plate 7;

[0028] In the specific implementation process, it is worth pointing out that the function of the spring 6 at the bottom of the inner wall of the housing 1 is to provide a certain elastic force to the filter element so that it can better contact with the inner wall of the housing 1, thereby ensuring the circulation of the engine oil. The function of the bypass valve 18 is that when the oil filter is blocked due to excessive impurities, the bypass valve 18 will automatically open, so that the engine oil will directly enter the main oil channel without passing through the filter, thereby maintaining the basic operation of the engine and preventing the engine from being seriously worn due to lack of lubricating oil.

[0029] Furthermore, the outer wall of the bypass valve 18 is sleeved with a central tube 11, the outer wall of the central tube 11 is sleeved with a filter paper 9, the outer wall of the filter paper 9 is provided with a plurality of slide grooves 8, the inner wall of the housing 1 is fixedly connected with a plurality of protrusions 5, and the protrusions 5 are slidably engaged with the inner wall of the slide groove 8;

[0030] In the specific implementation process, it is worth pointing out that impurities in the engine oil will be filtered out by the filter paper 9 to ensure that the engine oil without impurities enters the engine. The filter paper 9 filters the engine oil for a long time, and the problem of clogging will occur over time, affecting the filtering effect. The filter paper 9 can be replaced by relying on the sliding connection between the multiple slide grooves 8 on the outer wall of the filter paper 9 and the protrusion 5, avoiding the replacement of the entire filter due to the clogging of the filter paper 9, which is too expensive.

[0031] Furthermore, the outer wall of the filter paper 9 is fixedly connected with a plurality of strong magnetic blocks 10;

[0032] In the specific implementation process, it is worth pointing out that impurities such as iron filings in the engine oil will be adsorbed by the strong magnetic block 10 on the outer wall of the filter paper 9, which reduces the filtering burden of the filter paper 9 and can increase the service life of the filter paper 9;

[0033] Furthermore, a second cover plate 12 is threadedly connected to the top of the central tube 11, and a check valve 13 is installed on the top of the second cover plate 12;

[0034] In the specific implementation process, it is worth pointing out that the function of the check valve 13 is to prevent the oil in the oil channel from flowing back to the oil pan after the engine is turned off. When the engine is started next time, the oil filter must be filled first so that the oil can reach the lubrication surface. With the check valve 13, the oil will not flow back to the oil pan after the engine is turned off, and there will be no oil shortage at the initial stage of the engine start.

[0035] Furthermore, a third cover plate 15 is buckled on the top of the housing 1, and a rubber sealing ring 14 is covered on the bottom of the third cover plate 15. The outer wall of the rubber sealing ring 14 is attached to the inner wall of the housing 1. A plurality of oil inlet holes 17 are provided on the top of the third cover plate 15, and an oil outlet hole 16 is provided on the top of the central tube 11.

[0036] In the specific implementation process, it is worth pointing out that an oil inlet cavity connected to the oil inlet hole 17 is formed between the shell 1 and the central tube 11. The engine oil enters the interior of the filter through the oil inlet hole 17 and is filtered by filtering devices such as the filter paper 9 and the strong magnetic block 10. The central tube 11 is connected to the oil outlet hole 16 to form an oil outlet channel. The unfiltered engine oil flows into the oil inlet cavity from the oil inlet hole 17, is filtered by the filter paper 9, and then enters the oil outlet channel and flows out through the oil outlet hole 16.

[0037] Specifically, on the basis of the above-mentioned embodiment 1, the function of the spring 6 at the bottom of the inner wall of the shell 1 is to provide a certain elastic force to the filter element, so that it can better contact with the inner wall of the shell 1, thereby ensuring the circulation of the engine oil. The function of the bypass valve 18 is that when the oil filter is blocked due to excessive impurities, the bypass valve 18 will automatically open, allowing the engine oil to enter the main oil channel directly without passing through the filter, thereby maintaining the basic operation of the engine and preventing the engine from being seriously worn due to lack of lubricating oil. Impurities in the engine oil will be filtered out by the filter paper 9 to ensure that oil without impurities enters the engine. The filter paper 9 filters the engine oil for a long time, which will cause clogging over time and affect the filtering effect. The filter paper 9 can be replaced by relying on the sliding and carding relationship between the multiple slide grooves 8 on the outer wall of the filter paper 9 and the protrusion 5, avoiding the replacement of the entire filter due to clogging of the filter paper 9, which is too expensive and has a lot of problems in the engine oil. Impurities such as iron filings will be adsorbed by the strong magnetic block 10 on the outer wall of the filter paper 9, which reduces the filtering burden of the filter paper 9 and increases the service life of the filter paper 9. The function of the check valve 13 is to prevent the oil in the oil channel from flowing back to the oil pan after the engine is turned off. At the next start, the oil filter must be filled first before the oil can reach the lubrication surface. With the check valve 13, the oil will not flow back to the oil pan after the engine is turned off, and there will be no oil shortage at the initial stage of engine start. An oil inlet cavity connected to the oil inlet hole 17 is formed between the outer shell 1 and the central tube 11. The oil enters the interior of the filter through the oil inlet hole 17 and is filtered by filtering devices such as the filter paper 9 and the strong magnetic block 10. The central tube 11 is connected to the oil outlet hole 16 to form an oil outlet channel. The unfiltered oil flows into the oil inlet cavity from the oil inlet hole 17, is filtered by the filter paper 9, and then enters the oil outlet channel and flows out through the oil outlet hole 16.
