Automobile muffler with high noise reduction performance

Abstract

The invention relates to the technical field of auxiliary devices of automobile mufflers, in particular to an automobile muffler with high noise reduction performance. The automobile muffler comprisesa shell, a left communicating pipe and a right communicating pipe. A muffling cavity is arranged inside the shell. The automobile muffler is characterized by further comprising a left first net plate, a left second net plate, a left fixing ring, a left rotary shaft, a left rotary rod, a left upper brush rod, a left lower brush rod, a right first net plate, a right second net plate, a right fixingring, a right rotary shaft, a right rotary rod, a right upper brush rod, a right lower brush rod, a driving lead screw, two groups of limit slide columns, an adjusting plate, a left adjusting shaft and a right adjusting shaft. The automobile muffler has the advantages that carbon deposits attached onto the inner walls of the left communicating pipe and the right communicating pipe can be timely cleaned by the automobile muffler, accordingly, carbon deposition can be reduced, influence of increase of carbon deposits on the flow degree of exhaust inside the left communicating pipe and the rightcommunicating pipe can be prevented, and use limitation can be lowered; accumulated water which is generated by means of condensation under cold conditions inside the muffling cavity further can be conveniently scraped, accordingly, the inner wall of the automobile muffler can be prevented from being corroded, and the use reliability can be improved.

[0002] As we all know, the car muffler with high noise reduction performance is a kind of car exhaust pipe used to silence the noise generated inside the engine exhaust pipe, so as to better reduce car noise and provide a comfortable driving experience for the whole vehicle. Auxiliary device, which has been widely used in the field of automobile noise reduction; the existing automobile muffler with high noise reduction performance includes a shell, a left connecting pipe and a right connecting pipe, the inside of the casing is provided with a muffler cavity, and There are multiple sets of sound-absorbing panels horizontally inside the sound-absorbing chamber, and the left and right ends of the casing are respectively provided with an air inlet and an exhaust port. side, and the right input end of the left connecting pipe communicates with the air inlet, the right connecting pipe is located on the right side of the housing, and the left input end of the right connecting pipe communicates with the exhaust port; the existing high noise reduction performance When the automobile muffler is used, first connect the shell with the automobile exhaust pipe through the left connecting pipe and the right connecting pipe, and then eliminate the noise generated inside the exhaust pipe through multiple groups of sound-absorbing plates inside the sound-absorbing chamber; now In the use of some automobile mufflers with high noise reduction performance, it is found that because the gasoline inside the automobile engine often occurs insufficient combustion, a lot of carbon deposits will be generated in the exhaust gas. After long-term use, the carbon deposits will adhere to the left connecting pipe and the right connecting pipe. On the inner wall of the pipe, the increase of carbon deposit will affect the smoothness of the exhaust gas inside the left and right connecting pipes, and the internal cleaning cannot be carried out, resulting in high limitations in its use; and when gasoline is burned, gasoline is mixed with air and then ignited and burned to discharge water. Steam and water vapor enter the interior of the muffler and condense into water droplets that accumulate inside the muffler and cannot be discharged in time. If it remains for a long time, the inner wall of the muffler will be corroded, resulting in low reliability
