As shown in fig. 1 and 2, in one embodiment, an exhaust system 10 is provided that includes an exhaust body 100 and a reed 200. Wherein, the exhaust body 100 is provided with an exhaust passage 110; reed 200 is disposed in discharge passage 110 such that the air flow in discharge passage 110 can excite reed 200 to resonate to adjust the quality of the discharge sound.

In use, the exhaust system 10 of the above embodiment delivers gas into the exhaust passage 110, so that the gas can excite the reed 200 to resonate to generate sound, thereby effectively adjusting the quality of exhaust sound and improving the comfort and commodity of the exhaust system 10. Compared with the traditional tone quality adjusting mode, the exhaust system 10 can be designed under the condition that the basic structure of the exhaust body 100 is not changed, the performance stability of the exhaust system 10 is ensured, and the design freedom of the exhaust system 10 is improved.

The connection section 210 is fixedly connected to the inner wall of the exhaust channel 110, and may be welded, glued, clamped, inserted or screwed.

Optionally, the connection section 210 is welded to the inner wall of the exhaust passage 110 as one body. Thus, reed 200 does not move relative to exhaust body 100, and ensures that the quality of exhaust sound of exhaust system 10 is stable, thereby improving the reliability of exhaust system 10. In addition, the reed 200 with different length, thickness or shape is welded in the different exhaust bodies 100, so that different frequencies and sizes of sound can be obtained when gas passes through the different exhaust bodies 100, and when the exhaust sound quality needs to be adjusted, only the different exhaust bodies 100 need to be replaced, so that the operation is simple and convenient.

Optionally, the inner wall of the exhaust channel 110 is provided with a connecting groove, and the connecting section 210 is provided as a connecting piece, and the connecting piece is in plug-in fit with the connecting groove. In this way, reed 200 is detachably connected with exhaust body 100, so that exhaust system 10 can obtain sounds with different frequencies and sizes by replacing reed 200 with different lengths, thicknesses or shapes, and the applicability of exhaust system 10 is improved.

In this embodiment, the two opposite sides of the inner wall of the exhaust channel 110 are respectively provided with a connecting groove, and the two sides of the connecting sheet along the radial direction of the exhaust channel 110 are in one-to-one corresponding plug-in fit with the two connecting grooves. In this way, the connection area between the connection piece and the inner wall of the exhaust passage 110 increases, so that the connection strength between the reed 200 and the exhaust body 100 increases, and the reliability and stability of the exhaust system 10 are improved.

As shown in fig. 2 and 3, in one embodiment, reed 200 further includes resonating section 220, resonating section 220 being spaced apart from the inner wall of exhaust passage 110. In this way, the resonance section 220 is prevented from colliding with the inner wall of the exhaust channel 110 to generate noise in the vibration process, so that the stability of the exhaust sound quality of the exhaust system 10 is ensured, and the reliability and stability of the exhaust system 10 are improved. Specifically, in the present embodiment, the resonance section 220 and the connection section 210 are formed by integrally molding. In this way, the ease of processing of the exhaust system 10 is improved.

As shown in fig. 3, alternatively, the distance between the two outer side walls of the resonance section 220 in the radial direction of the exhaust passage 110 and the inner wall of the exhaust passage 110 is the same. In this way, the resonance section 220 is ensured not to collide with the inner wall of the exhaust passage 110 during the vibration process, and the reliability and stability of the exhaust system 10 are improved.

The distance between the two outer side walls of the resonance section 220 along the radial direction of the exhaust channel 110 and the inner wall of the exhaust channel 110 can be flexibly adjusted according to the actual use requirement.

In particular, in the present embodiment, the gas is inputted from the end of the exhaust passage 110 near the connection section 210 and is discharged from the end of the exhaust passage 110 near the resonance section 220. In this way, the gas around the connection section 210 can flow smoothly and smoothly to the periphery of the resonance section 220, so that the gas is prevented from forming vortex at the connection position of the connection section 210 and the resonance section 220 to disturb the gas flow direction in the exhaust channel 110, the stability of the exhaust sound quality of the exhaust system 10 is ensured, and the reliability and stability of the exhaust system 10 are improved. In the embodiment, two arc surfaces 211 are provided, and the two arc surfaces 211 and the connecting section 210 are disposed in one-to-one correspondence along two sides of the radial direction of the exhaust passage 110.

As shown in fig. 1 and 2, the resonance section 220 is optionally provided with a turbulence through hole 221, and the turbulence through hole 221 is used to disturb the airflow in the exhaust passage 110. In this way, the turbulence through holes 221 can play a role in turbulence on the gas in the exhaust passage 110, so that the exhaust system 10 can obtain more different exhaust sounds, and the applicability of the exhaust system 10 is improved.

The number and the inner diameter of the turbulent flow channels can be flexibly adjusted according to the actual use requirement.

In this way, the stress on one side of the reed 200 close to the first exhaust branch is kept consistent with the stress on one side of the reed 200 close to the second exhaust branch, so that the influence of deformation of the reed 200 in the use process on the exhaust sound quality of the exhaust system 10 is avoided, and the reliability and stability of the exhaust system 10 are improved. In particular, in the present embodiment, the turbulence through hole 221 is used to communicate the first exhaust branch with the second exhaust branch.
