[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional automobile oil filter, the oil filter is an integrated structure. When the filter screen inside the oil filter is blocked, it is difficult to remove the filter screen separately for cleaning and replacement. The entire oil filter is often replaced, which will cause waste of other parts in good condition. The device designs the automobile oil filter to be detachable, so that the internal filter screen can be taken out separately for cleaning and replacement, reducing the waste of parts;

[0014] 2. When replacing the internal filter element, the upper shell and the lower shell are connected by threads. At the same time, there are anti-slip patterns on the outside of the upper shell and the lower shell, which are easy to separate by hand. You can also use a wrench or other tools to clamp the hexagonal force block and separate them. After the upper shell and the lower shell are separated, the filter seat, support plate and support spring can be easily taken out. After cleaning and replacing the filter, put the rubber ring on the top of the filter seat. First send the filter seat into the upper shell, and then place the support spring between the two sets of support plates and send it into the upper shell. Finally, twist the lower shell to connect the lower shell with the upper shell. The support spring pushes the support plate to provide support for the filter seat. Under the action of the rubber ring, it is re-sealed with the mounting plate to complete the separate replacement of the filter. This solves the problem that most automotive oil filters are inconvenient to take out the internal filter separately for cleaning and replacement, and the overall replacement is prone to waste of parts.

[0015] 3. When filtering the engine oil, two sets of installation pipes fix the oil inlet pipe and the oil outlet pipe respectively. The engine oil enters the device from the oil inlet pipe. When the engine oil enters the limit column from the filter, the impurities in the engine oil are blocked by the filter and retained, and the clean engine oil flows out through the oil outlet pipe at the end of the installation pipe. When the filter is blocked, the impurities on the filter block the channel, and it is difficult for the engine oil to flow through the filter, which increases the pressure in the filter. The bypass spring is located between the limit ring and the piston, pushing the piston to block the bottom channel of the limit column. When the oil pressure increases, the engine oil pushes the piston upward to open the bottom channel of the limit column, so that the engine oil can flow out through the oil outlet pipe at the end of the installation pipe to prevent the engine from losing oil lubrication.

The hexagonal force block 202 is arranged on the bottom of the lower shell 201. The engine oil is contained through the lower shell 201, and the hexagonal force block 202 is convenient for using tools to disassemble the device.

[0024] See also Figure 3 In this embodiment, the support assembly 3 includes a support plate 301 and a support spring 302; the support plate 301 is arranged inside the lower shell 201, and a support spring 302 is arranged on one side of the support plate 301; the support plate 301 is pushed by the support spring 302 to provide support force for the filter seat 501.

[0025] See also Figure 4 In this embodiment, the mounting assembly 4 includes a mounting plate 401, a limiting column 402 and a limiting ring 403. The limiting column 402 is arranged above the support plate 301, and the mounting plate 401 is arranged above the limiting column 402. The limiting ring 403 is arranged on the inner side of the limiting column 402. The limiting column 402 is fixed to the upper shell 101 through the mounting plate 401, and the filter seat 501 is prevented from shaking by the limiting column 402. The bypass spring 602 is supported by the limiting ring 403; the filter assembly 5 includes a filter seat 501, a filter screen 502 and a rubber ring 503. The limiting column 402 A filter seat 501 is arranged on the outside, a filter screen 502 is arranged on the inside of the filter seat 501, and a rubber ring 503 is arranged above the filter seat 501. The filter screen 502 is placed on the filter seat 501 to fix the engine oil, and the rubber ring 503 is used to strengthen the seal between the filter seat 501 and the mounting plate 401; the bypass assembly 6 includes a piston 601 and a bypass spring 602, a bypass spring 602 is arranged at the bottom of the limit ring 403, and a piston 601 is arranged at the bottom of the bypass spring 602, and the piston 601 is pushed by the bypass spring 602 to close the channel at the bottom of the limit column 402.

[0026] When filtering the engine oil, the two sets of mounting tubes 102 fix the oil inlet pipe and the oil outlet pipe respectively. The engine oil enters the device from the oil inlet pipe. When the engine oil enters the limit column 402 from the filter screen 502, the impurities in the engine oil are blocked by the filter screen 502 and the clean engine oil flows out through the oil outlet pipe at the end of the mounting tube 102.

[0027] When the filter is clogged, impurities on the filter screen 502 block the channel, and it is difficult for the oil to flow through the filter screen 502, which increases the pressure in the filter. The bypass spring 602 is located between the limit ring 403 and the piston 601, pushing the piston 601 to block the bottom channel of the limit column 402. When the oil pressure increases, the oil pushes the piston 601 to move upward, opening the bottom channel of the limit column 402, so that the oil can flow out through the oil outlet pipe at the end of the installation pipe 102, preventing the engine from losing the lubrication of the oil.
