When the engine is operated for a period of time, a lot of impurities are doped in the oil, at this time, when the oil with a certain pressure in the engine and doped with impurities presses down the elastic sheet 221 from the liquid inlet 22, so that the elastic sheet 221 is separated from the shielding of the liquid inlet 22, and then the oil enters the outer chamber 32 through the liquid inlet 22, the impurities in the oil can be attached to the outer surface of the filter element 30 in the process of filtering the oil by the filter element 30 and entering the filter chamber 31, and when the impurities on the outer surface of the filter element 30 are attached to a certain degree, the filtering capability of the filter element 30 can be greatly reduced.
Meanwhile, referring to fig. 8-11, as the oil in the engine continuously enters the outer chamber 32, the oil in the outer chamber 32 overcomes the pushing force of the elastic restoring member 37 against the second lifting member 36, so as to push the second lifting member 36 to slide downwards, when the second lifting member 36 slides downwards until the pressing portion 362 is in abutting contact with the transition member 338, the second lifting member 36 stops briefly sliding downwards, then as the oil in the engine continuously enters the outer chamber 32, the oil in the outer chamber 32 continuously overcomes the pushing force of the elastic restoring member 37 against the second lifting member 36, and the pressing portion 362 gradually presses the transition member 338 into the mounting member 33, when the transition member 338 is pressed and completely accommodated in the mounting member 33, the second lifting member 36 slides downwards at a relatively high speed until the pressing portion 362 is in abutting contact with the limiting member 337, in the process, under the assistance of the first piston cylinder 411 and the second piston cylinder 421, the first matching rod drives the first lifting member 34 to move relatively short time in a short time to the pushing force of the elastic restoring member 37 against the second lifting member 36, and the pressing portion 331 is made to gradually push the transition member 338 into the mounting member 33, and the filter element 31 is made to slide down towards the outer surface of the first chamber 31, and the filter element 30 is made to pass through the first chamber 33, and the filter element 31 is made to be suddenly pushed down towards the outer surface of the filter chamber 30 by the first chamber 31, and the filter element 30 is made to be made to slide down towards the outer surface of the filter element 31 by the first chamber 31.
In the process that the first lifting member 34 slides upwards, the first annular member 341 drives the driven block 35 to rotate by a certain angle, so that the driving member 353 rotates by a certain angle, and the blade 354 rotates by a certain angle along with the driving member 353, it can be understood that the rotation of the blade 354 can assist the filter chamber 31 to flow to the outer chamber 32, so that the blade 354 provides a certain power for back flushing to a certain extent, in addition, because the driving member 353 has an inverted cone structure, namely, the driving member 353 has a conical surface, in the process that the first lifting member 34 slides upwards, the oil in the filter chamber 31 can be pushed upwards, so that most of the oil in the filter chamber 31 can play a role in back flushing on the filter element 30 with the aid of the conical surface, and the impurity removing effect is improved.
Furthermore, with the aid of the first piston cylinder 411 and the second piston cylinder 421, the first lifter 34 and the second lifter 36 are linked, when the second lifter 36 slides down, a part of the oil in the filter chamber 31 is sucked into the outer chamber 32, at this time, the oil pressure in the filter chamber 31 is reduced, that is, the oil amount discharged from the liquid outlet 21 is reduced in a short time, however, when the second lifter 36 slides down, the first lifter 34 slides up, the sum of the volumes of the filter chamber 31 and the first chamber 331 is reduced due to the upward sliding of the first lifter 34, so that the upward sliding of the first lifter 34 compensates for the reduced amount of the oil discharged from the liquid outlet 21, and the oil amount discharged from the liquid outlet 21 is stabilized, so that the stable operation of the engine is achieved.
When the impurities attached to the outer surface of the filter element 30 are washed down, the filter element 30 recovers the filtering capability, the oil in the outer chamber 32 can enter the filter chamber 31 continuously through the filter element 30 and is output from the liquid outlet 21 for the engine, at this time, the elastic reset piece 37 pushes the second lifting piece 36 upwards and enables the second lifting piece to reset gradually, and at the same time, the first lifting piece 34 slides downwards in the first chamber 331 and resets gradually with the aid of the first piston cylinder 411 and the second piston cylinder 421, so that the back washing cleaning of the impurities is completed.
It will be appreciated that when the outer surface of cartridge 30 is again subjected to a greater amount of impurities, second lifter 36 again slides downwardly, and the above process is repeated until cartridge 30 regains its filtering capability.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
