Background technology
With the improvement of living standards, in life anything of people is all in the trend development towards simplicity, people couple Increasing in the degree of dependence of electricity, increasing personal or enterprise purchases generator as stand-by power supply.Generator is A kind of relatively conventional generator, it is deep due to the advantages that it easily starts, stable working to be favored.But during generator operation Noise radiation is more strong, causes serious noise pollution, disturbs the normal live and work of people, influences physical and mental health.Hair , there are many kinds the reason for motor generation loud noise, wherein, exhaust noise is the main part of generator noise, because This, control generator exhaust noise is the key for reducing generator noise.Muffler typically is installed on generator blast pipe, And muffler generally use single-bin structure, it is impossible to preferably slowed down to air-flow, make air-flow caused by generator pass through this After kind muffler, still there is higher flow velocity and stronger impulsive force, cause the noise-reduction effect of muffler undesirable, And this generator is heavier, welding is inconvenient, not readily portable.Therefore, how a kind of generating of features simple structure is provided Machine muffler, after it is used for generator, good deceleration can be carried out to air-flow, lowers its impulsive force, obtains good disappear Audio fruit, turn into the important technological problems that those skilled in the art need to solve.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of portable digital generator muffler, this muffler structure Simply, decrease of noise functions is powerful, and while easy processing is welded.
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.
Brief description of the drawings
Fig. 1 is the structure diagram of portable digital generator muffler.
Fig. 2 is the top view of portable digital generator muffler.
Fig. 3 is the upward view of portable digital generator muffler.
With specific embodiment, the utility model will be further described below in conjunction with the accompanying drawings, referring to figure:1- shells;11- Upper casing;12- lower casings;2- air inlet pipe;21- gas outlets;3- escape pipes;4- airways;The upper airways of 41-;Airway under 42-;5- Dividing plate;6- bases;7- epicoeles;8- cavity of resorptions.
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.
