Wherein:
A. annular groove 8 has been seted up to the inside of installing piece 2, and oil return tank 81 has been seted up to the below of filter core 21, and annular groove 8 is linked together with oil return tank 81.

D. The oil separator 1 includes a first chamber located at an inlet end of the filter element 21 and a second chamber located at an outlet end of the filter element 21.
During normal operation, the driven gear 34 is in the second position, an oil-gas mixture generated by the engine enters the first chamber through the air inlet of the oil separator 1, the oil-gas mixture collides with the helical blade 31 and pushes the rotating shaft 3 to rotate, oil in the oil-gas mixture after the oil-gas mixture collides with the helical blade 31 adheres to the outer wall of the helical blade 31 and falls to the bottom of the first chamber along with the rotation of the rotating shaft 3 to enter the oil storage tank 11 on the oil separator 1;
after the oil-gas mixture collides with the helical blade 31, the oil-gas mixture passes through the filter element 21 on the mounting block 2 and enters the second chamber, the helical blade 31 in the oil separator 1 performs primary collision separation on the oil-gas mixture, and the filter element 21 performs secondary filtering separation on the oil-gas mixture, so that the oil-gas separation efficiency is effectively improved. The thrust of the high-temperature and high-pressure gas sprayed out of the filter element 21 to the driven gear 34 is larger than the suction of the magnetic part 4 to the driven gear 34 in normal operation;
when the filter element 21 is blocked, the thrust of the high-temperature and high-pressure gas sprayed from the filter element 21 to the driven gear 34 is smaller than the suction of the magnetic piece 4 to the driven gear 34, when the driven gear 34 on the rotating frame 33 runs to the blocked filter element 21, the driven gear 34 is adsorbed by the magnetic piece 4 in the filter element 21, so that the driven gear 34 is meshed with the meshing structure on the filter element 21, and the driven gear 34 is at the first position;
during the process that the driven gear 34 is attracted to the meshing structure on the filter element 21 by the magnetic element 4, the driven gear 34 drives the fixed shaft 342 to move towards the filter element 21, the first rack 343 on the fixed shaft 342 drives the tooth column 344 to rotate, and the tooth column 344 drives the second rack 345 to move towards the direction far away from the expansion element 36; the expansion member 36 may be a balloon or a rubber ring; after the second rack 345 is separated from the extrusion of the expansion piece 36, the driving gear 32 drives the driven gear 34 to rotate along with the continuous rotation of the rotating shaft 3, the driven gear 34 drives the filter element 21 to rotate, in the process of rotating the filter element 21, due to the influence of centrifugal force, oil on the filter element 21 is thrown out and flows out from the oil return groove 81, and the outlet of the oil return groove 81 faces the first chamber;
after the filter element 21 is cleaned, the oil-gas mixture can be continuously sprayed out of the filter element 21, so that the driven gear 34 is continuously pushed to move towards the direction of the rotating frame 33, and meanwhile, as the first elastic piece 35 is a tension spring, a certain tension is applied to the driven gear 34 from the tension spring, so that the driven gear 34 can be gradually disengaged from the meshing structure to return to the second position; when the driven gear 34 returns to the second position, the first rack 343 on the fixed shaft 342 drives the second rack 345 to move towards the expansion member 36 through the tooth column 344, so that the second rack 345 extrudes the expansion member 36 and the rotating frame 33 is fixedly connected with the rotating shaft 3, and the rotating shaft 3 continues to drive the rotating frame 33 to rotate.
The second embodiment:
as shown in figures 2 to 5 of the drawings,
the air outlet end of the filter element 21 is fixedly provided with a rotating block 5 which is rotationally connected with the mounting block 2, and the air inlet end of the filter element 21 is rotationally connected with a fixed block 6 which is rotationally connected with the mounting block 2;
one surface of the fixed block 6, which is close to the filter element 21, is provided with a limiting groove 61;
a fixed pipe 7 is fixedly arranged inside the filter element 21, one end of the fixed pipe 7 is fixedly connected with the rotating block 5, and the other end of the fixed pipe 7 is rotatably connected with the fixed block 6; a limiting rod 71 is arranged inside the fixed block 6, one end of the limiting rod 71 is rotatably connected with the rotating block 5, and the other end of the limiting rod 71 is fixedly connected with the fixed block 6; a spiral strip 72 is arranged on the outer wall of the limiting rod 71, one end of the spiral strip 72 is fixedly connected with the magnetic part 4, and the other end of the spiral strip 72 is connected with the limiting groove 61 on the fixing block 6; the shape of the helical strip 72 is flat;
Wherein:
A. the rotating block 5 is provided with an accommodating cavity 51 for the driven gear 34 to enter, and the meshing structure is a tooth 52 arranged on the accommodating cavity 51.
B. The second elastic member 75 is a compression spring;
C. the outer wall of the magnetic part 4 is provided with a sliding groove 41, the outer wall of the fixed pipe 7 is provided with a limiting strip 42 matched with the sliding groove 41, and the limiting strip 42 is in radial elastic sliding connection with the inner wall of the fixed pipe 7.
The driven gear 34 is influenced by the magnetic part 4 to enter the accommodating cavity 51 on the rotating block 5 and is meshed with the teeth 52 in the accommodating cavity 51; after the driven gear 34 is meshed with the teeth 52, along with the rotation of the rotating shaft 3, the driving gear 32 on the rotating shaft 3 drives the driven gear 34 to rotate, the driven gear 34 drives the rotating block 5 to rotate, the rotating block 5 drives the filter element 21 to rotate, and the filter element 21 throws oil out under the influence of centrifugal force;
when the driven gear 34 moves towards the filter element 21, the driven gear 34 can rapidly enter the accommodating cavity 51 due to the magnetic attraction of the magnetic piece 4 to the driven gear 34;
in the process that the rotating block 5 drives the filter element 21 to rotate, the filter element 21 drives the fixed pipe 7 to rotate, the fixed pipe 7 drives the magnetic part 4 to rotate through the meshing of the limiting strip 42 and the sliding groove 41, the magnetic part 4 drives the spiral strip 72 to twist and generate energy accumulation, the spiral strip 72 contracts towards the air inlet end of the filter element 21 in the twisting process of the spiral strip 72, and the spiral strip 72 generates torque in the process of contracting towards the air inlet end of the filter element 21 due to the flat shape of the spiral strip 72; the spiral strip 72 drives the magnetic part 4 to move towards the air inlet end of the filter element 21 in the contraction process, the magnetic part 4 contacts with the limiting block 74 in the movement process, and the limiting block 74 blocks the magnetic part 4, so that the spiral strip 72 cannot continuously drive the magnetic part 4 to move towards the filter element 21; with the continuous rotation of the filter element 21, one end of the spiral strip 72, which is far away from the magnetic element 4, rotates in the limiting groove 61, so that the magnetic element 4 can continue to rotate with the rotation of the filter element 21;
with the throwing of the oil liquid in the filter element 21, the centrifugal force of the filter element 21 is gradually increased, so that the limiting rod 71 compresses the second elastic element 75 and moves towards the outer wall direction of the filter element 21, and finally the limiting block 74 is separated from the limiting of the magnetic element 4; then, the magnetic element 4 can continuously move towards the air inlet end of the filter element 21, the driven gear 34 gradually disengages from the magnetic attraction with the magnetic element 4 in the moving process of the magnetic element 4, and finally the driven gear 34 quickly returns to the second position under the pulling of the first elastic element 35, and the rotating shaft 3 drives the rotating frame 33 to continuously rotate after the driven gear 34 returns to the second position;
when the driven gear 34 returns to the second position, the magnetic element 4 moves to the end of the limiting bar 42 close to the filter element 21 and is separated from the limiting bar 42, so that the sliding groove 41 deviates from the position opposite to the limiting bar 42, and then the accumulated energy of the spiral bar 72 is released to push the magnetic element 4 to move towards the rotary block 5, because the limiting bar 42 is elastically connected in a sliding manner along the radial direction of the fixed pipe 7, so that when the magnetic element 4 moves towards the rotary block 5, the magnetic element 4 extrudes the limiting bar 42 out of the inner diameter of the fixed pipe 7, so that the magnetic element 4 can rapidly move towards the rotary block 5, even if the limiting block 74 blocks the magnetic element 4, the instantaneous kinetic energy released by the spiral bar 72 can also rush out of the block of the limiting block 74 to return to the initial position, and when the magnetic element 4 returns to the initial position, the torque generated by the spiral bar 72 itself is released, so that the sliding groove 41 on the magnetic element 4 is re-engaged with the limiting bar 42 again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
