One side of the second fixing ring 301 is fixedly connected with a second baffle 303, and the other side of the second fixing ring 301 is fixedly connected with a second partition board 302. A plurality of second V-shaped holes 304 are formed inside the second baffle 303. Through the second V-shaped holes 304 and the first V-shaped holes 203, when sound waves enter the chamber, part of the sound waves can be prevented from being vertically reflected and then reflected out from the second V-shaped holes 304 and the first V-shaped holes 203, thereby improving the reduction effect on sound waves.

[0023] In this embodiment, as Figure 2 、 Figure 1 and Figure 5 shown, a communication component 4 is arranged inside the box body 1. The communication component 4 includes an air inlet pipe 401. The air inlet pipe 401 penetrates through one side of the box body 1 and extends into the box body 1. One end of the air inlet pipe 401 penetrates through the box body 1 and two first sound insulation board assemblies 2 in sequence. A plurality of round holes 402 are formed inside the air inlet pipe 401. One side of the box body 1 is fixedly communicated with an exhaust pipe 403.

A clamping pin 603 is fixedly connected to one side of the limiting plate 604. When the waste gas enters through the intake pipe 401, part of the generated sound wave enters the chamber formed between the two round holes 402 through the round holes 402 on the intake pipe 401. This part of the sound wave is reflected between the two first baffles 202, so that the sound wave is gradually weakened. And part of the sound wave enters the chamber formed by the first baffle 202 and the first partition plate 204 through the first baffle 202 on the first baffle 202, and this part of the sound wave will also be gradually consumed with continuous reflection. The remaining part of the sound wave enters the chamber formed by the second sound insulation plate assembly 3 and the second sound insulation plate assembly 3 through the intake pipe 401 and is gradually consumed after reflection. And part of the sound wave enters the chamber formed by the inner wall of the box body 1 and the first sound insulation plate assembly 2 through the connecting pipe 404 and is consumed and weakened through continuous reflection. Finally, the waste gas is discharged through the exhaust pipe 403. With long-term use, carbon will gradually accumulate on the inner wall of the box body 1 and the surfaces of the first baffle 202 and the second baffle 303. By pressing the clamping pin 603, the clamping pin 603 moves into the movable shell 605, so that the clamping column 602 is separated from the clamping pin 603. Under the action of the gravity of the opening and closing plate 503, the sealing strip 502 and the opening and closing plate 503 are separated from the frame 501, so that the personnel can clean the inside of the box body 1.

[0026] In this embodiment, as Figure 3 and Figure 6 shown, the top of the clamping pin 603 abuts against the side surface of the clamping column 602, and the bottom of the clamping pin 603 is an inclined surface.

[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, when the exhaust gas enters through the intake pipe 401, part of the generated sound wave enters the chamber formed between the two round holes 402 through the round hole 402 on the intake pipe 401. This part of the sound wave is reflected between the two first baffles 202, causing the sound wave to be gradually weakened. And part of the sound wave enters the chamber formed by the first baffle 202 and the first partition 204 through the first baffle hole on the first baffle 202, and this part of the sound wave will also be gradually consumed with continuous reflection. The remaining part of the sound wave enters the chamber formed by the second sound insulation plate assembly 3 and the second sound insulation plate assembly 3 through the intake pipe 401 and is gradually consumed after reflection. There is also part of the sound wave that enters the chamber formed by the inner wall of the box body 1 and the first sound insulation plate assembly 2 through the connecting pipe 404 and is consumed and weakened through continuous reflection. Finally, the exhaust gas is discharged through the exhaust pipe 403. With long-term use, carbon deposits will gradually accumulate on the inner wall of the box body 1 and the surfaces of the first baffle 202 and the second baffle 303. By pressing the retaining pin 603, the retaining pin 603 moves into the movable shell 605, causing the clamping column 602 to separate from the retaining pin 603. Under the gravity of the opening and closing plate 503, the sealing strip 502 and the opening and closing plate 503 are separated from the frame 501, so that the personnel can clean the inside of the box body 1.
