The invention discloses a cyclone dust removal long-life automobile muffler. A muffling cylinder flattening piece is in a rectangular shape and is provided with a plurality of dual-door-window holes. The dual-door-window holes comprise rectangular sound through holes formed in the muffling cylinder flattening piece. The sound through holes are provided with beams. The axes of the beams coincide with the connecting lines of the midpoints of the opposite sides of the sound through holes. The two sides of each beam are connected with a wing plate A and a wing plate B. Each sound through hole is divided into two symmetric through holes with the same area through the corresponding beam. An acute angle A is formed between each wing plate A and the muffling cylinder flattening piece. An acute angle B is formed between each wing plate B and the muffling cylinder flattening piece. The area of each wing plate A is equal to the area of the region, on the left side of the beam, of the corresponding sound through hole. The area of the wing plate B is equal to the area of the region, on the right side of the beam, of the corresponding sound through hole. The cyclone dust removal long-life automobile muffler has the advantages of being simple in structure and strong in anti-noise capacity.
Description
technical field [0001] The invention relates to the field of automobile mufflers, in particular to a cyclone dust removal and long-life automobile muffler. Background technique [0002] The muffler end cover assembly is an important component of automobile noise reduction. The existing structure is mainly composed of a muffler and an end cover. The muffler is provided with evenly arranged circular sound passage holes, and the end cover is a flat plate structure. The above-mentioned muffler is used behind the Alto car to reduce the noise. When the original output noise of the engine is 95 decibels, after the muffler treatment of the end cover assembly of the muffler, the output is 73.58 decibels, and the noise is still relatively large. The traditional structure is a direct current structure with wind passage. After a long time, the air passage holes inside the muffler will be blocked, making the muffler unusable. Therefore, the life of a general muffler is 3 to 5 years. Co...
