What the purpose of this utility model was realized in：
A kind of portable digital generator muffler, including shell, the side of the shell are provided with an air inlet pipe, shell
Opposite side be provided with an escape pipe, the enclosure is provided with a dividing plate, and the inside of shell is separated into by the dividing plate
Chamber and cavity of resorption, airway is provided with the dividing plate, and airway includes being arranged on the upper airway of dividing plate upper surface and is arranged on
The lower airway of dividing plate lower surface, upper airway and lower airway are interconnected.
Preferably：The right side of the air inlet pipe is provided with a gas outlet, and the escape pipe is siphunculus..
Preferably：The escape pipe connects epicoele through epicoele connection cavity of resorption, the air inlet pipe through cavity of resorption.
Preferably：The airway is shaped as serpentine, and the entrance of the upper airway is away from air inlet pipe, lower airway
It is arranged on the left side of escape pipe.
Preferably, the shell includes upper casing and lower casing and is connected with dividing plate.
Preferably, one end of the lower casing is provided with a fixed seat, and fixed seat is welded and fixed with air inlet pipe.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1. shell internal body portion is divided into the spaces of two sealings by dividing plate, the space of the sealing is upper inner chamber and lower interior
Chamber, is provided with airway and lower airway on dividing plate, the upper upper inner chamber of airway connection, the lower lower airway of airway connection, on
Lower airway is connected to form a loop, and one end of shell body is provided with air inlet pipe, and air inlet pipe connects through lower inner cavity and upper inner chamber
Logical, the opposite side of shell body is provided with escape pipe, and escape pipe connects through upper inner chamber with lower inner cavity, and gas is thin by this bending
Small loop, the gas outlet of airway is smaller, so device out is seldom, the internal diameter of escape pipe is very big, in airway out
Device can not be full of whole escape pipe, gas can be made not compressed in gas outlet in outlet, reduce gas in outlet
Friction in pipe, so as to reduce noise, it can must effectively play a part of noise reduction.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,
As Figure 1-3, a kind of portable digital generator muffler, including shell 1, the side of the shell 1 are set
There is an air inlet pipe 2, the opposite side of shell 1 is provided with an escape pipe 3, it is characterised in that：The shell 1 is internally provided with a dividing plate
5, the inside of shell 1 is separated into epicoele 7 and cavity of resorption 8 by the dividing plate 5, and airway 4 is provided with the dividing plate 5, and airway 4 wraps
The upper airway 41 for being arranged on the upper surface of dividing plate 5 and the lower airway 42 for being arranged on the lower surface of dividing plate 5 are included, upper airway 41 is with
Airway 42 is interconnected, and forms a unidirectional gas flowing path, two inner chambers it is sufficiently bulky, airway 4 enters
Gas port and gas outlet very little, make gas slowly to enter, gas from lower airway 4 come out when because gas output very little
The reason for, prevent gas from filling the tracheae 3 that overfills, it is possible to reduce impulsive force of the gas on escape pipe 3, so as to reduce noise.
Preferably, the right side of the air inlet pipe 2 is provided with a gas outlet 21, and the escape pipe 3 is siphunculus, can be extended
