DETAILED DESCRIPTION

[0021] 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.

[0022] In one embodiment, a quick-release filter for an oil pump is provided. Figure 1-4 As shown, the oil pump quick-release filter includes a base 1, a shell 2 and a filter element 3, wherein the base 1 is made of metal, the shell 2 adopts a nylon shell or a metal shell according to the pressure of the use scenario, and the filter element 3 can be made of filter paper, nylon cloth or polymer materials according to the use requirements. The filter element 3 is arranged in the shell 2, and the shell 2 is arranged on the base 1, so that the filter element 3 is assembled in the base 1 and the shell 2, and one of the shell 2 and the base 1 is provided with a bolt insertion hole. In this embodiment, a bolt insertion hole 21 is provided in the middle of the top of the shell 2, and a bolt insertion hole 22 is provided at the bottom. A screw hole 11 is correspondingly provided in the middle of the bottom of the seat 1. The oil pump quick-release filter is also provided with a long bolt 4 that enters from the bolt penetration hole 21, penetrates the filter element 3 and is connected to the screw hole 11. The filter element 3 is clamped between the base 1 and the housing 2 by installing the long bolt 4; the base 1 is provided with a first oil port 12, a first oil passage 13, a second oil passage 14 and a second oil port 15. The first oil port 12 is connected to the filter element 3 through the first oil passage 13, and the second oil port 15 is connected to the interlayer space 22 between the filter element 3 and the housing 2 through the second oil passage 14. Figure 4As shown, the flow direction of the oil in the first oil channel 13 is the direction of the left arrow sequence in the base 1 or the opposite direction, and the flow direction of the oil in the second oil channel 14 is the direction of the right arrow sequence in the base 1 or the opposite direction. The first oil port 12 and the second oil port 15 have one oil inlet and the other oil outlet respectively. The main function of the oil pump quick-release filter is to filter out impurities in the oil.

[0023] The oil pump quick-release filter is used as follows: during assembly, the filter element 3 is set in the housing 2, the housing 2 is set on the base 1, and then the long bolt 4 is inserted from the bolt insertion hole 21, penetrates the filter element 3 and is connected to the screw hole 11, and the filter element 3 is clamped between the base 1 and the housing 2 by installing the long bolt 4 to complete the assembly. When in use, the oil pump quick-release filter is installed in the oil circuit of the engine oil pump. The first oil port 12 and the second oil port 15 are respectively one oil inlet and the other oil outlet. The oil enters through the oil inlet of the oil pump quick-release filter, and is discharged from the oil outlet after being filtered by the filter element 3. Specifically, the interior of the filter element 3 is a cavity structure, and the side wall of the filter element 3 is a filter layer. If the first oil port 12 is the oil inlet, the oil entering the first oil port 12 is connected to the filter element 3 through the first oil channel 13. The bottom of the filter element 3 is open and the top is closed. The oil entering the filter element 3 flows out from the side wall to the interlayer space 22 between the filter element 3 and the housing 2. This process allows the oil to be filtered, and the outflowing oil flows through the second oil channel 14 to the second oil port 15 and continues to flow into the engine for combustion. When maintenance or replacement of the filter element 3 is required, the long bolt 4 is directly unscrewed and removed from the screw hole 11, so that the base 1 and the housing 2 can be disassembled, and the filter element 3 can be taken out for maintenance or replacement, which is very convenient. The filter element 3, the housing 2 and the base 1 are connected by a long bolt 4, thereby avoiding the problem of a large volume of the connection structure of the three components caused by the annular hoop, thereby reducing the installation space occupied by the filter. In addition, the nut of the bolt rod can be easily disassembled and assembled using an ordinary wrench by connecting with the long bolt 4, eliminating the need for a special wrench for the filter.

[0024] Further, in another embodiment, Figure 1 As shown, a spring 5 for pressing the filter element 3 is sleeved on the long bolt 4 of the oil pump quick-release filter. The filter element 3 can be pressed by setting the spring 5, and filter elements 3 of different heights within a certain height range can be installed in the housing 2.

[0025] Further, in another embodiment, Figure 1-4As shown, a center hole 31 for passing a long bolt 4 is provided in the middle of the top surface of the filter element 3 of the oil pump quick-release filter. The top surface of the filter element 3 is a circular top plate, and the center hole 31 is located in the middle thereof. A first sealing gasket 41 and a spring gasket 51 which are sleeved on the long bolt 4 are provided in sequence on the upper side of the center hole 31. The long bolt 4 can be smoothly penetrated and installed through the provided center hole 31. The provided first sealing gasket 41 can seal the center hole 31, and the spring gasket 51 is conducive to stable support of the lower end of the spring 5.

[0026] Further, in another embodiment, Figure 1-4 As shown, a support ring portion 16 is provided in the base 1 of the oil pump quick-release filter. The support ring portion 16 is a circular ring wall arranged upward from the bottom surface of the internal space of the base 1. The first oil channel 13 passes through the left side of the support ring portion 16 and is connected to the inside thereof. A lower opening 32 is provided at the bottom of the filter element 3. The bottom surface of the filter element 3 is a circular bottom plate. The lower opening 32 is arranged in the middle of the circular bottom plate. The edge of the lower opening 32 is supported on the support ring portion 16 by a second sealing gasket 33. The second sealing gasket 33 plays a sealing role.

[0027] Further, in another embodiment, Figure 1-4 As shown, the oil pump quick-release filter is provided with a stud portion 17 in the support ring portion 16 , and the screw hole 11 is provided in the stud portion 17 . The stud portion 17 is provided to facilitate the arrangement of the screw hole 11 .

[0028] Further, in another embodiment, Figure 1-4 As shown, the bolt insertion hole 21 of the oil pump quick-release filter is arranged at the middle position of the top of the housing 2, and a third sealing gasket 23 sleeved on the long bolt 4 is arranged on the top of the housing 2, and sealing is performed by the third sealing gasket 23.

[0029] Further, in another embodiment, Figure 1-4 As shown, the base 1 of the oil pump quick-release filter is provided with an annular groove 18 for docking with the shell 2. The shell 2 is cylindrical with a conical top. The annular groove 18 is also annular. A fourth sealing gasket 19 is provided in the annular groove 18 for sealing.

[0030] Further, in another embodiment, Figure 1-4 As shown, the first oil port 12 and the second oil port 13 of the oil pump quick-release filter are both provided with internal threads so as to be connected to the oil circuit of the oil pump.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
