[0030] Referring to Figure 1 - Figure 2 , the present utility model provides an oil filter, which includes a housing and a filter element 3. The housing includes an end cap 2 and an outer shell 1 connected to the end cap 2. A filter chamber is provided inside the outer shell 1, and the end cap 2 closes the filter chamber. An oil inlet 7 and an oil outlet 8 are provided on the end cap 2; the filter element 3 is installed in the filter chamber, and an oil inlet passage 5 communicating with the oil inlet 7 is formed between the filter element 3 and the outer shell 1, and an oil outlet passage 6 communicating with the oil outlet 8 is formed inside the filter element 3; wherein, an anti-slip boss 4 is provided on the outer surface of the outer shell 1.

[0031] In the housing, the outer shell 1 is a cylindrical or prismatic container with one end open, and the inner cavity of the outer shell 1 forms the filter chamber; the end cap 2 is connected to the open end of the outer shell 1, and an oil inlet 7 and an oil outlet 8 both communicating with the filter chamber are provided on the end cap 2, wherein the oil outlet 8 is located at the center of the end cap 2, and the oil inlet 7 is plural and is arranged around the oil outlet 8.

[0032] The filter element 3 is inserted into the filter chamber from the open end of the outer shell 1, and an oil inlet passage 5 is formed between the housing and the filter element 3, and the oil inlet passage 5 is annular; a central cylinder is provided inside the filter element 3, filter paper is arranged on the outer ring of the central cylinder, and an oil outlet passage 6 is formed inside the central cylinder, and the oil outlet passage 6 communicates with the oil outlet 8.

[0033] It can be understood that the oil to be filtered first enters the oil inlet passage 5 through the oil inlet 7, then passes through the filter paper of the filter element 3 for filtration, and the filtered oil is output to the outside of the oil filter through the oil outlet passage 6 and the oil outlet 8, completing the oil filtration process.

[0034] The outer shell 1 in the housing is provided with the anti-slip boss 4, so that the anti-slip boss 4 can increase the friction between the user and the outer shell 1, thereby facilitating the disassembly and assembly of the oil filter, facilitating the maintenance of the engine, and further prolonging the service life of the engine.

[0035] The oil filter provided by the present utility model includes a housing comprising an end cap 2 and a housing 1, and a filter element 3. A filter cavity is provided inside the housing 1, and the end cap 2 closes the filter cavity. An oil inlet 7 and an oil outlet 8 are provided on the end cap 2. The filter element 3 is installed in the filter cavity, and an oil inlet passage 5 communicating with the oil inlet 7 is formed between the filter element 3 and the housing 1. An oil outlet passage 6 communicating with the oil outlet 8 is formed inside the filter element 3. In this way, impurities in the oil can be filtered by the filter element 3. At the same time, by providing anti-slip protrusions 4 on the outer surface of the housing 1, the disassembly and assembly of the oil filter can be facilitated, the maintenance of the engine can be made convenient, and the service life of the engine can be extended.

[0036] In a specific embodiment of the present utility model, the number of the anti-slip protrusions 4 is multiple, and the multiple anti-slip protrusions 4 are evenly arranged along the circumferential direction of the housing 1. By providing multiple anti-slip protrusions 4, the density on the outer periphery of the housing 1 can be increased, so that the anti-slip grip on the housing 1 can be realized at different angles, thereby improving the operation convenience.

[0037] In a specific embodiment of the present utility model, the number of the anti-slip protrusions 4 is at least two. Specifically, the two anti-slip protrusions 4 are arranged oppositely, which can not only ensure the anti-slip grip of the housing 1, but also reduce the material cost of the housing 1.

[0038] In a specific embodiment of the present utility model, the length of the anti-slip protrusion 4 is not less than half of the length of the housing 1. By limiting the length of the anti-slip protrusion 4, the anti-slip grip on the housing 1 can be realized for holding at different positions, thereby improving the operation convenience. Preferably, the anti-slip protrusion 4 extends from the connection between the housing 1 and the end cap 2 to the other end of the housing 1.

[0039] In a specific embodiment of the present utility model, the cross-section of the anti-slip protrusion 4 is in the shape of a rounded rectangle, a hemisphere, a rectangle or an arc. In this way, the structure of the anti-slip protrusion 4 can be enriched. Preferably, the anti-slip protrusion 4 is arranged in an arc shape.

[0040] In a specific embodiment of the present utility model, the anti-slip protrusion 4 and the housing are of an integrally formed structure. In this way, the anti-slip protrusion 4 and the housing can be integrally processed, thereby improving the processing efficiency.

[0041] In a specific embodiment of the present utility model, a Tesla valve for enabling unidirectional conduction from the oil inlet 7 to the oil inlet passage 5 is provided between the oil inlet 7 and the oil inlet passage 5.

[0042] By setting a Tesla valve with one-way conduction between the oil inlet passage 5 and the oil inlet 7, the one-way conduction function is realized, preventing the engine oil in the main oil passage from returning to the oil pan after the engine stops, so as to prevent the friction pair from being worn without oil when the vehicle is started next time. Moreover, compared with the existing technical solution that uses a rubber valve plate to form a one-way valve, it has many advantages. For example, since the Tesla valve has a fixed geometric shape, it can withstand the influence of factors such as high and low temperatures and pulse pressures, and can make up for the disadvantages of traditional rubber valve plates that are prone to aging, tearing and easy damage, with a higher service life, making the one-way conduction function from the oil inlet 7 to the oil inlet passage 5 more durable, greatly improving the use reliability of the oil filter, and further improving the use reliability of the engine.

[0043] The second aspect of the present utility model also provides an oil filter assembly, including the oil filter of any one of the above, and the oil filter is installed on the oil filter seat.

[0044] It can be understood that the oil filter assembly also includes an oil filter seat. The oil filter is installed on the oil filter seat, the housing abuts against the oil filter seat, the oil inlet 7 is connected to the main oil passage for engine oil supply through the oil filter seat, and the oil outlet 8 is connected to the main oil passage of the engine through the oil filter seat.

[0045] The oil filter is detachably installed on the oil filter seat through the housing, which is convenient for replacing the oil filter. When the filter element 3 in the oil filter fails, the old oil filter seat can be removed and replaced with a new oil filter. At the same time, after the oil filter is removed, the blocked position in the housing can be dredged and cleaned.

[0046] The ways for the oil filter seat and the housing to achieve detachable connection can adopt threaded connection, snap connection, clamp connection, etc., which can meet the requirements of convenient disassembly and assembly.

[0047] Since the oil filter is installed on the oil filter assembly, therefore, the oil filter assembly at least has the beneficial effects of the above oil filter, which will not be elaborated here.

[0048] The third aspect of the present utility model also provides an engine, including the above oil filter assembly.

[0049] The oil filter assembly is connected to the main oil passage of the engine to filter the engine oil. Since the above oil filter assembly is installed on the engine, the beneficial effects brought by the oil filter assembly can be seen in the above embodiments, which will not be elaborated here.

[0050] Finally, it should be noted that 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 foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
