[0032] The working principle and use process of this utility model:

[0033] Before use, the air outlet pipe 113 and the air inlet 112 are connected to the delivery pipe respectively; when in use, the delivery pipe is opened and the switch is pressed to start the motor 121, so that the motor 121 drives the guide pipe 5 to rotate. At the same time, the oil mist passes through the pipe body 51 upward to contact the guide cover 53, and is transported into the through hole 531 through the bottom arc surface of the guide cover 53 and discharged through the through hole 531. The discharged oil mist then contacts the guide block 54, is diverted by the guide block 54 and discharged through the air outlet. Since the delivery pipe rotates at this time, the oil mist discharged through the air outlet passes through the first filter 2 evenly, and then reaches the second filter 3 and the third filter 4 in turn to be fully filtered. After filtering, it is discharged through the air outlet pipe 113. When the oil mist evenly contacts the first filter 2, the second filter and the third filter 4, it can be evenly filtered, and the amount of oil mist filtered each time is even, so that the filtering effect and efficiency are improved. In addition, by rotating the guide pipe 5, the filtering surfaces of the first filter 2, the second filter 3 and the third filter 4 can be uniformly filtered. The oil is then filtered out of the filter screen 111 and the filter screen 112 is removed. At the same time, the oil collected on the outer wall of the guide block 54 drips into the upper end surface of the guide cover 53 through the guide rod 541. The oil is discharged into the collection box 511 through the arc structure of the upper end surface of the guide cover 53 through the air outlet and collected. When cleaning the interior and replacing the filter screen, the bolt 122 is disengaged from the threaded hole 1112 by turning the bolt 122 counterclockwise, and then the cover 12 is removed. At this time, the locking teeth 1211 is disengaged from the slot 5131, and the groove 111 is cleaned or the oil in the collection box 511 is processed, or the filter is replaced. When replacing the first filter 2, the second filter 3 or the third filter 4, it is only necessary to pull out the ring 114 to complete the disassembly, and then close the cover 12, insert the output end of the motor 121 into the mounting tube 513, and insert the tooth 1211 into the slot 5131, and turn the bolt 122 clockwise to make it engage with the threaded hole 1112 again.
