Abstract
The invention relates to a muffler used for an exhaust system. The muffler comprises a main pipeline, the main pipeline comprises at least one air inlet and at least one air outlet, sound absorption materials are filled in the main pipeline, the air inlets and the air outlets are respectively communicated with the main pipeline perpendicularly, and each air inlet and each air outlet are connected with one end of an air inlet pipe and one end of an air outlet pipe respectively. Since the air inlet pipes and the air outlet pipes are connected on the main pipeline, sound waves pass through the air inlet pipes, the main pipeline and the air outlet pipes successively to muffle successively so that better muffling effect is achieved. Additionally, the air inlet pipes are capable of changing the mounting direction of the muffler, so that the muffler is more flexible in application.
