Run through housing；One end of described first noise reduction transverse tube is air inlet；The other end of described first noise reduction transverse tube is the first venthole；
First noise reduction transverse tube of described first venthole side is provided with air valve；Enclosure interior is located at by described noise reduction bend pipe；Described noise reduction
The vertical section of bend pipe is welded as a whole with the first noise reduction transverse tube；One end of the horizontal segment of described noise reduction bend pipe uses closure designs；
The downside of noise reduction bend pipe is located at by described second noise reduction transverse tube；One end of described second noise reduction transverse tube is run through baffle plate and gives vent to anger with first
Hole is positioned at the same side；One end that described second noise reduction transverse tube runs through baffle plate is provided with the second venthole；Described second noise reduction transverse tube
The other end uses closure designs.
Preferably, described air valve is driven by wireless signal and uses wireless remote sensing to be controlled.
Preferably, the outside wall surface of described noise reduction bend pipe, the first noise reduction transverse tube, the second noise reduction transverse tube is closely fitted with steel wire
Net；All intersect on described noise reduction bend pipe and the second noise reduction transverse tube and be provided with bloop.
Preferably, it is filled with silencing cotton between described steel wire and the inwall of housing.
Compared with prior art, the beneficial effects of the utility model are: this utility model noise reduction drum is by using air valve
Design, can be remotely controlled by wireless, and then the discharge capacity of gas in control the first noise reduction transverse tube, thus controls automobile last or end syllable
Size, and the design of noise reduction bend pipe can realize air valve of completely closed time, make gas and noise pass sequentially through noise reduction bend pipe,
Bloop, silencing cotton, then discharged by the second hush pipe, greatly reduce the quality of noise reduction by increasing stroke so that disappear
Audio fruit is substantially.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: one singly enter double go out Valve controlling noise reduction drum, bag
Include housing 1, noise reduction bend pipe the 2, second noise reduction transverse tube 3；Described housing 1 outline uses thin wall cylindrical stretching design；Described housing 1
Be respectively arranged at two ends with a baffle plate 4；Described housing 1 is internal is provided with the first noise reduction transverse tube 5；The two of described first noise reduction transverse tube 5
End extends through housing 1；One end of described first noise reduction transverse tube 5 is air inlet 6；The other end of described first noise reduction transverse tube 5 is
First venthole 7；First noise reduction transverse tube 5 of described first venthole 7 side is provided with air valve 8；Shell is located at by described noise reduction bend pipe 2
Body 1 is internal；The vertical section of described noise reduction bend pipe 2 is welded as a whole with the first noise reduction transverse tube 5；The horizontal segment of described noise reduction bend pipe 2
One end use closure designs；The downside of noise reduction bend pipe 2 is located at by described second noise reduction transverse tube 3；The one of described second noise reduction transverse tube 3
End runs through baffle plate 4 and is positioned at the same side with the first venthole 7；One end that described second noise reduction transverse tube 2 runs through baffle plate 4 is provided with
