[0029] The buffer mechanism 3 is located outside the housing 2, and the buffer mechanism 3 is slidably connected to the inner wall of the protective shell 1, and is arranged in a ring array along the central axis of the protective shell 1;

When in use, the gas enters the interior of the shell 2 from the packaging cover 16 installed on the left side of the shell 2. The side baffle 4, the sound insulation board 5 and the partition plate 8 divide the interior of the shell 2 into a plurality of chambers of different volumes. When the gas enters the interior of the shell 2, the gas flows in each chamber through the intake pipe 7, the connecting pipe 9 and the exhaust pipe 10. The rubber pad 6 can buffer the vibration generated when the gas flows through the intake pipe 7. In this process, sound waves are emitted from the holes opened on the surfaces of the connecting pipe 9 and the exhaust pipe 10, and are reflected back and forth between the side baffle 4, the sound insulation board 5 and the partition plate 8, and finally cancel each other out, thereby achieving a sound-absorbing effect;

The arc-shaped plate 31 is located outside the shell 2, and the roller 35 is rollingly connected to the outer wall of the shell 2. When an object hits the muffler, the protective shell 1 and the buffer mechanism 3 can buffer the impact force. In this process, the object first contacts the arc-shaped plate 31 and forces the arc-shaped plate 31 to drive the fixed column 32 to approach the shell 2. At this time, the rollers 35 on both sides roll along the surface of the shell 2. At the same time, the rotating frames 33 on both sides rotate relatively, and force the torsion spring 34 to be twisted under force, so as to buffer the impact force, thereby achieving the purpose of protecting the entire muffler.

[0032] The inner wall of the shell 2 is fixedly connected with a fixing sleeve 11, the outer wall of the fixing sleeve 11 is fixedly connected with a compression spring 12, the left end of the compression spring 12 is fixedly connected with a sliding ring 13, the inner wall of the shell 2 is slidably connected with an annular sleeve 14, the inner wall of the annular sleeve 14 is fixedly connected with a filter screen 15, the inner wall of the sliding ring 13 is slidably connected with the outer wall of the fixing sleeve 11, the outer wall of the sliding ring 13 is slidably connected with the inner wall of the shell 2, and the left side of the shell 2 is threadedly connected with a packaging cover 16, the right side of the packaging cover 16 is in contact with the left side of the annular sleeve 14, and in the process of the gas packaging cover 16 entering the interior of the shell 2, the solid particles contained in the gas will adhere to the surface of the filter screen 15 fixedly connected to the annular sleeve 14, thereby reducing the impact and erosion of the solid particles on the inner wall of the shell 2, thereby improving the service life of the shell 2, and then improving the service life of the muffler;

[0033] After a long period of use, when the filter 15 needs to be replaced, the packaging cover 16 is rotated to separate the packaging cover 16 from the shell 2. At this time, under the elastic force of the compression spring 12, the sliding ring 13 slides along the outer wall of the fixed sleeve 11 and the inner wall of the shell 2, and the annular sleeve 14 together with the filter 15 is pushed out from the inside of the shell 2. At this time, the filter 15 can be replaced.

[0034] Working principle:

[0035] When in use, the gas enters the interior of the housing 2 from the packaging cover 16 installed on the left side of the housing 2. During this process, the solid particles contained in the gas will adhere to the surface of the filter screen 15 fixedly connected to the annular sleeve 14, thereby reducing the impact and erosion of the solid particles on the inner wall of the housing 2, thereby increasing the service life of the housing 2, and further increasing the service life of the muffler;

[0036] After a long period of use, when the filter 15 needs to be replaced, the packaging cover 16 is rotated to separate the packaging cover 16 from the housing 2.

[0037] The side baffles 4, the sound insulation board 5 and the partition board 8 divide the interior of the housing 2 into a plurality of chambers of different volumes. When the gas enters the interior of the housing 2, the gas flows in each chamber through the intake pipe 7, the connecting pipe 9 and the exhaust pipe 10. The rubber pad 6 can buffer the vibration generated when the gas flows through the intake pipe 7. In this process, sound waves are emitted from the holes opened on the surfaces of the connecting pipe 9 and the exhaust pipe 10, and are reflected back and forth between the side baffles 4, the sound insulation board 5 and the partition board 8, and finally cancel each other out, thereby achieving a sound-absorbing effect.

[0038] When an object hits the silencer, the protective shell 1 and the buffer mechanism 3 can buffer the impact force. During this process, the object first contacts the arc plate 31, and forces the arc plate 31 to drive the fixed column 32 to approach the shell 2. At this time, the rollers 35 on both sides roll along the surface of the shell 2, and the rotating frames 33 on both sides rotate relatively, and force the torsion spring 34 to twist under force, so as to buffer the impact force, thereby achieving the purpose of protecting the entire silencer.
