Meanwhile, as the filler 2 is filled in the first silencing cavity 111 and the second silencing cavity 121, the filler 2 can also reduce the flow rate of gas in the first silencing cavity 111 and the second silencing cavity 121, and further reduce noise. In addition, the silencer 100 is simple in structure and low in production cost, and the fillers 2 in the first silencing cavity 111 and the second silencing cavity 121 can be replaced respectively according to noise types, so that different silencing requirements are met, and the universality of the silencer 100 is improved.
In some embodiments of the present invention, the first muffling chamber 111 and the second muffling chamber 121 are arranged in a first direction, and the cross-sectional area of the first muffling chamber 111 is smaller than the cross-sectional area of the second muffling chamber 121; or the cross-sectional area of the first sound-deadening chamber 111 is larger than that of the second sound-deadening chamber 121; or the cross-sectional area of the first sound-deadening chamber 111 is equal to the cross-sectional area of the second sound-deadening chamber 121. It is understood that the gas entering the muffler 100 through the gas inlet 14 passes through the first sound-deadening chamber 111 and the second sound-deadening chamber 121 in this order and is discharged from the gas outlet 15. The cross-sectional area of the first sound-deadening chamber 111 is smaller than that of the second sound-deadening chamber 121, so that the cross-sectional area of the sound-deadening chamber is suddenly increased, and therefore, sudden changes of impedance are caused in the sound transmission process, and further, the middle and low frequency parts of noise are eliminated, and then, the filler 2 filled in the first sound-deadening chamber 111 and the second sound-deadening chamber 121 absorbs the noise, so that composite sound deadening is realized, and the sound-deadening effect of the silencer 100 is further improved.
Further, the filler 2 in the first muffling chamber 111 is the filler 2 for muffling the high frequency part of the sound, so that the noise of the gas entering the muffler 100 is first muffled by the first muffling chamber 111 (i.e., resistive muffling), and then the cross-sectional area of the second muffling chamber 121 is suddenly increased to muffle the middle and low frequency parts of the noise, thereby muffling the noise of the gas entering the muffler 100.
