In this embodiment, specifically, the filter holes 511 are formed in the purifying device 51, the purifying device 51 is made of a metal material, and a catalyst for purifying the automobile exhaust is coated on an inner wall of each filter hole 511, so as to ensure that the automobile exhaust can effectively form oxidation and reduction catalysis when passing through the filter holes 511, thereby ensuring that the overall purifier can have an effect of purifying the automobile exhaust.
The filter holes 511 comprise two guide parts 512 and two connecting parts 513, and the two guide parts 512 in each filter hole 511 are symmetrically arranged and are respectively connected to two ends of the connecting part 513; the one-time rotation angle of the purification device 51 is n × 180 °, wherein n is any positive odd number from 1 to n;
