[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment of a combined oil filter, comprising an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are combined and provided with a disassembly assembly, which can be conveniently disassembled and assembled, so as to facilitate the later maintenance and directly replace the filter element 5, without replacing all of them, saving costs, and improving convenience and disassembly efficiency. A filter element 5 for filtering oil impurities is arranged between the upper shell 1 and the lower shell 2. The upper shell 1 is arranged above the lower shell 2, and a disassembly assembly is arranged between the upper shell 1 and the lower shell 2. The disassembly assembly includes a limit rod 35 that can slide into the card slot 36 and slide into the limit slot 34 to limit the limit block 3, so that the upper shell 1 is combined and connected with the lower shell 2 to reach the limit block 3. The bottom end of the upper shell 1 is fixedly connected with a connecting rod 33 that supports and drives the limit block 3 to move.

[0031] The limit block 3 is fixedly connected to the bottom end of the connecting rod 33, and the connecting rod 33 is set to be L-shaped. After being set to the L-shape, it can slide into the slide groove 37, and then the left protrusion of the L-shape is rotated to be stuck in the card groove 36, so that the effect of limited installation can be quickly achieved, which improves the convenience of installation, so that the filter element 5 can be easily replaced without replacing all of them, saving costs. The outer wall of the upper shell 1 begins to have an annular groove that provides space for the movement of the guide ring 32 and the movement of the spring 31. The inner wall of the annular groove is slidably connected to the guide ring 32 that drives the limit rod 35 to move. The bottom end of the guide ring 32 is fixedly connected to the limit rod 35 that can slide into the limit groove 34 to limit the limit block 3. The limit rod 35 passes through and is slidably connected to the bottom end of the upper shell 1.

[0032] Reference Figure 1 , Figure 3 and Figure 4 A sealing assembly is provided at the top of the lower shell 2, and the sealing assembly includes a sealing ring 4 which is made of rubber material to increase the sealing performance after the upper shell 1 and the lower shell 2 are combined and connected. The sealing ring 4 is slidably connected to the top of the lower shell 2, and a positioning block 42 is fixedly connected to the rear surface of the sealing ring 4 to cooperate with the spring 2 41 so that the sealing ring 4 is always in close contact with the upper shell 1.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The guide ring 32 is elastically connected to the upper shell body 1 through a spring 31, one end of the spring 31 is fixedly connected to the top inner wall of the annular groove, and the other end of the spring 31 is fixedly connected to the top of the guide ring 32. By moving the guide ring 32 upward to squeeze the spring 31, the limiting rod 35 is driven to slide out of the limiting groove 34 and align with the slide groove 38. The upper shell body 1 is slightly rotated to drive the limiting block 3 to rotate and slide out of the card groove 36, so that the limit of the upper shell body 1 can be quickly released. After the upper shell body 1 is quickly removed, the filter element 5 can be replaced. A slide groove 37 is provided at the top of the lower shell body 2 for providing movement of the limiting block 3, and the limiting block 3 slides on the inner wall of the slide groove 37.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A slot 36 is provided on the outer side of the outer wall of the lower shell 2 near the outer side of the slide groove 1 37, which can clamp the limit block 3 and limit the position. The limit block 3 is clamped on the inner wall of the slot 36, and the slot 36 is connected to the slide groove 1 37. A slide groove 2 38 is provided on the front surface of the top of the lower shell 2 near the slide groove 1 37 for providing movement of the limit rod 35. The limit rod 35 slides on the inner wall of the slide groove 2 38. A limit groove 34 is provided at the bottom of the slide groove 1 37, which can cooperate with the limit rod 35 to slide into the limit groove 34 to limit the limit block 3, and the limit rod 35 is inserted into the inner wall of the limit groove 34.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The positioning block 42 is elastically connected to the lower shell body 2 through the spring 2 41. One end of the spring 2 41 is fixedly connected to the upper inner wall of the lower shell body 2, and the other end of the spring 2 41 is fixedly connected to the bottom end of the positioning block 42. After the upper shell body 1 and the lower shell body 2 are assembled and connected and installed, the sealing ring 4 can be extruded in cooperation with the upper shell body 1, so that the sealing ring 4 moves downward to drive the positioning block 42 to extrude the spring 2 41. The reverse force of the extrusion of the spring 2 41 can make the sealing ring 4 always closely fit the bottom end of the upper shell body 1, thereby increasing the tightness of the connection between the upper shell body 1 and the lower shell body 2. The sealing ring 4 is inserted into the inner wall of the bottom end of the upper shell body 1.

[0036] Working principle: When in use, the upper shell 1, the lower shell 2 and the filter element 5 inside are combined, and the disassembly and assembly components and the sealing components are used to achieve the effect of quick maintenance and replacement of the filter element 5, without the need to replace all of them. When installing, place the upper shell 1 above the lower shell 2, so that the limit block 3 at the bottom of the connecting rod 33 slides into the slide groove 1 37 at the top of the lower shell 2, and at the same time, the bottom end of the limit rod 35 is squeezed through the inner wall of the bottom end of the slide groove 2 38, so that the limit rod 35 drives the guide ring 32 to move upward to squeeze the spring 1 31. Since the connecting rod 33 is set to L shape, at this time, the upper shell body 1 is rotated so that the left side protrusion of the L-shape is stuck in the card groove 36, and the reverse force of the extrusion of the spring 1 31 drives the guide ring 32 and the limit rod 35 to return and slide into the limit groove 34 to limit the limit block 3, thereby realizing rapid limit installation. At the same time, the bottom end of the upper shell body 1 will squeeze the sealing ring 4, and the sealing ring 4 drives the positioning block 42 to compress the spring 2 41. The reverse force of the spring 2 41 makes the sealing ring 4 fit tightly to the bottom end of the upper shell body 1, thereby increasing the sealing of the connection, so that the oil filter can stably and effectively filter oil impurities.

[0037] When the filter element 5 needs to be replaced, the guide ring 32 is pulled upwards to squeeze the spring 1 31, driving the limit rod 35 to slide out of the limit groove 34 and align it with the slide groove 2 38, and then the upper shell 1 is slightly rotated to drive the limit block 3 to slide on the inner wall of the slide groove 1 37, so that the limit block 3 rotates and slides out of the slot 36, and the limit of the upper shell 1 is released. The upper shell 1 can be quickly removed and the filter element 5 can be replaced without replacing all of it, which saves costs and improves convenience and disassembly and assembly efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
