As shown in fig. 1 and 6 to 7, which are second embodiments of the present invention, the difference from the first embodiment is that a collecting plate 211 for collecting impurities is fixedly installed at an inner wall of a housing 21, the collecting plate 211 is L-shaped, one end of the collecting plate 211 is fixedly connected with the housing 21, and a stopper 212 for blocking the impurities collected by the collecting plate is fixedly connected at the other end thereof, so that the collecting plate 211 and the housing 21 define a collecting chamber for collecting the impurities and having a passage.
In the present embodiment, the collecting plate 211 may have a plurality, and the plurality of collecting plates 211 may be arranged at intervals along the circumferential direction of the inner wall of the housing 21.
When the filter element 22 is blocked, engine oil entering between the shell 21 and the filter element 22 has larger impact force on the first blocking block 25 for blocking the filter element 22, the first blocking block 25 can be enabled to rotate and displace along the thread groove 241, and certain extrusion force is generated on engine oil in the filter element 22 due to movement of the first blocking block 25, so that engine oil can recoil the filter element 22, impurities filtered out of the filter element 22 can fall into a collecting cavity of the collecting plate 211, the rotation angle of the first connecting block 251 is smaller than one hundred eighty degrees in the process, after cleaning is completed, due to the fact that the first connecting block 251 is in a structure of being eccentric downwards, and meanwhile, when engine oil reenters the filter element 22 and generates certain extrusion force again on the second blocking block 26, the first blocking block 25 can automatically rotate and reset to the end part of the filter element 22.
Compared with the first embodiment, the present embodiment can facilitate the cleaning of impurities on the filter element 22 by the user, so as to reduce the replacement frequency of the filter element 22.
As shown in fig. 8 to 12, in a third embodiment of the present invention, on the basis of the second embodiment, a fixing groove 2513 is formed on a connection ring 2512, a plurality of circumferentially distributed through holes are formed inside the connection ring 2512, the through holes are used for allowing part of engine oil to pass through, a ratchet block 2514 is slidably mounted inside the fixing groove 2513, the ratchet block 2514 has a first surface and a second surface along the circumferential direction of the connection ring 2512, wherein the first surface is a straight surface extending radially along the connection ring 2512, the second surface is an arc surface, the ratchet block 2514 is connected with the bottom wall of the fixing groove 2513 through a return spring 2515, a collar 28 is movably sleeved on the outer surface of the connection ring 2512, a plurality of ratchet grooves 281 are formed on the inner wall of the collar 28, the ratchet blocks 2514 can be matched and inserted with the ratchet grooves 281, a slide bar 282 is fixedly mounted on the outer surface of the collar 28, a slide groove 221 for slidably connecting the slide bar 282 is formed on the inner wall of the filter element 22, and the slide groove 221 extends axially along the filter element 22.
The end department that filter core 22 kept away from connecting seat 2 is equipped with baffle 231, and baffle 231 ring is established in the periphery side of connecting rod 24, and elastic component 23 sets up between baffle 231 and shell 21 to the top is pushed to baffle 231 and filter core 22 elasticity, when filter core 22 takes place to block up, the engine oil that gets into between shell 21 and the filter core 22 is at first strikeed baffle 231 and makes it keep away from filter core 22, can avoid the frictional force that baffle 231 and filter core 22 meet and produce to influence the rotation of filter core 22.
When the filter element is seriously blocked, the engine oil entering between the shell 21 and the filter element 22 firstly extrudes the baffle 231 to enable the engine oil to be far away from the filter element 22, then the engine oil can generate larger extrusion force on the first blocking block 25 for blocking the filter element 22, the first blocking block 25 drives the connecting ring 2512 to rotate, at the moment, the positive rotating ratchet block 2514 is located in the ratchet groove 281, the first blocking block 25 can drive the filter element 22 to rotate in the process of rotating and moving towards the connecting seat 2 through the matching of the straight surface of the ratchet block 2514 and the ratchet groove 281 and the matching of the sliding strip 282 and the sliding groove 221, and the engine oil inside the filter element 22 can generate reverse impact force on the filter element 22, so that impurities which are backflushed and fall down on the filter element 22 can enter the collecting plate 211 at the bottom of the shell 21 to avoid the impurities from falling onto the filter element 22 again to block the filter element 22.
After the filter element is cleaned and is unblocked, the baffle 231 automatically resets to stop the filter element 22 again, the first plugging block 25 can be rotationally reset under the influence of gravity and the action of the engine oil extrusion force entering the filter element 22, and in the process, due to the arrangement of the arc-shaped surface structure on the ratchet block 2514, the ratchet block 2514 can not drive the lantern ring 28 and the filter element 22 to rotate again when reversing.
Compared with the second embodiment, the impurity that drops on the filter element 22 can be concentrated and the bottom of the shell 21 can be avoided to drop the filter element 22 again to block the filter element, and the purpose of good cleaning effect is achieved.
