Specifically, in this embodiment, the thickness of the second inner cylinder 6 is 4mm, and the thickness of the second outer cylinder 7 is 2mm, so that the occupation of the cylinder body on the space of the cylinder wall of the flow guiding ring 1 can be reduced, a sound-deadening chamber can be formed more effectively, and the sound-deadening effect can be improved.
In this embodiment, the thickness of the second outer cylinder 7 is smaller than that of the second inner cylinder 6, because the second inner cylinder 6 is closer to the airflow, the effect of the vibration generated when the airflow flows on the second inner cylinder 6 is larger, and if the thickness of the second inner cylinder 6 is too small, the second inner cylinder 6 vibrates along with the airflow, so that the vibration and noise reduction effect of the second inner cylinder 6 on the airflow is reduced.
Preferably, the rectifying plate 2 is provided with a second muffling hole 9.
The rectifying plate 2 is made of sound-absorbing material.
When the airflow flows through the rectifying plate 2, the rectifying plate 2 can not only perform the rectifying function on the airflow, but also perform the silencing function, thereby reducing the airflow flowing loss and the airflow flowing noise.
When the inner wall of the flow guide ring 1 and the rectifying plate 2 are both provided with the silencing holes, the two are combined for silencing, so that the pneumatic noise and the air cavity resonance sound can be greatly reduced.
It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed. The foregoing is only a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present application, and these modifications and variations should also be considered as the protection scope of the present application.
