Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present embodiment proposes an intake silencer device including:
the cylinder shell 11 is provided with an inner cavity, a first partition plate 12 is fixed in the inner cavity, the inner cavity is divided into a silencing cavity 13 and a purifying cavity 14 by the first partition plate 12, and the cylinder shell 11 is provided with an air inlet 15 and an air outlet 16;
a silencing assembly disposed in the silencing chamber 13;
the air purification subassembly, the air purification subassembly is located in purifying cavity 14 just the air purification subassembly is fixed on first division board 12, be equipped with on first division board 12 and be used for the air purification subassembly the inlet end with the opening that the amortization chamber 13 communicates.
The technical effect of the scheme is as follows: the inner cavity of the cylinder shell 11 is reasonably separated through the first isolation plate 12, then the corresponding silencing component and the air purification component are installed, air purification and noise reduction can be achieved in the inner cavity of the cylinder shell 11, the design space of the whole machine is reduced, the process manufacturing cost is saved, and the whole machine is compact, stable and reliable.
As an implementation of this embodiment, the sound attenuating assembly includes:
