The air guide cover 4 cooperates with the air guide port 3 to allow air to enter during the driving of the automobile and reduce the blockage problem of the exhaust pipe 1 caused by the blockage of the output pipe 2. Among them, three air guide covers 4 are contacted with barbs 5, and an auxiliary rod 6 is welded on the bottom side of the barbs 5. A fixed sleeve 7 is sleeved on one side of the auxiliary rod 6. The barbs 5 are used to connect the air guide cover 4. The gear column 11 can rotate the adjusting rod 8. At this time, the fixed sleeve 7 moves toward the side of the resonator and then fits the output pipe 2. The through hole on the inner side of the fixed sleeve 7 corresponds to the air guide port 3. Under normal circumstances, the movable ring 14 There is a certain distance between the fixed sleeve 7 and the detection probe 13 detects the airflow discharged from the output pipe 2. When a problem with the automobile exhaust is detected, the drive motor is started to drive the drive gear 12 to rotate and the gear column 11 to rotate, and the adjusting rod 8 moves to one side of the resonator, and the moving ring 14 fits the fixed sleeve 7, so as to filter the exhaust gas.
