The air inlet pipe, back pressure pipe, the first swan neck are respectively positioned on the intracorporal middle part of shell, and correspond to each other between it, institute State the second swan neck, third swan neck is respectively positioned on the intracorporal upper end of shell, the exhaust pipe is located at the intracorporal lower end of shell.
One end end that the back pressure pipe is located at the back pressure storehouse is provided with back pressure head, and the both ends side wall of back pressure pipe On be respectively equipped with aperture.
The back pressure head is the hat, and section is arc-shaped.
Metal mesh is provided in the noise elimination storehouse.
The invention has the advantages that
The present invention is directly vented by air inlet pipe enters the noise elimination of back pressure storehouse back pressure, then the noise elimination storehouse damping by filling metal mesh disappears Sound, then pass sequentially through three whirlwind storehouses and will be vented in storehouse and rotate noise elimination, so that the reduction of very big effect when gas is discharged Noise has the value of popularization and application.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention.
In figure: 1- shell, 2- partition, the first whirlwind of 3- storehouse, 4- back pressure storehouse, the second whirlwind of 5- storehouse, 6- noise elimination storehouse, 7- third Whirlwind storehouse, 8- air inlet pipe, 9- back pressure pipe, 10- back pressure head, the first swan neck of 11-, the second swan neck of 12-, 13- third swan neck, 14- metal mesh, 15- exhaust pipe.
Specific embodiment:
Referring to attached drawing.
A kind of automobile exhaust muffler includes shell 1, partition 2, air inlet pipe 8, back pressure pipe 9, the first swan neck 11, Spaced partition 2, the partition 2 is distributed in the shell 1 in double section belt arm pipe 12, third swan neck 13 and exhaust pipe 15 1 inner cavity of shell is divided into the first whirlwind storehouse 3, back pressure storehouse 4, the second whirlwind storehouse 5, noise elimination storehouse 6 and third whirlwind storehouse 7, described first An air inlet pipe 15 crossed is equipped in whirlwind storehouse 3, one end of the air inlet pipe 15 is located at outside the shell 1, and the other end is located at back It presses in storehouse 4, one end of the back pressure pipe 9 is located in back pressure storehouse 4, and the other end passes through the second whirlwind storehouse 5 and is located in noise elimination storehouse 6, institute The one end for stating the first swan neck 11 is located in noise elimination storehouse 6, and the other end is elbow and is located in third whirlwind storehouse 7 that described second is curved One end of head tube 12 is located in third whirlwind storehouse 7, and the other end passes through noise elimination storehouse 6 and is located in the second whirlwind storehouse 5, and its end is curved One end of head, the third swan neck 13 is located in the second whirlwind storehouse 5, and the other end passes through back pressure storehouse 4 and is located at first whirlwind In storehouse 3, and its end is elbow, and the exhaust pipe 15 for crossing shell, the air inlet of the exhaust pipe 15 are equipped in the shell 1 End is located in the first whirlwind storehouse 3, and the other end sequentially passes through back pressure storehouse 4, the second whirlwind storehouse 5, noise elimination storehouse 6 and third whirlwind storehouse 7 And it stretches out outside shell 1.
