Description
Technical field
The utility model is related to generators to be vented field, and in particular to a kind of generator muffler.
Background technology
Generator will produce larger noise at work, therefore in use would generally install silencer to subtracting
Small noise.But in actual use, noise is generated by air pulsation, therefore vibrations can be conducted to muffler body,
Vibrations occur to make a noise so as to cause silencer, while traditional silencer mostly uses bending cavity and reduces noise,
But air-flow hits silencer internal wall and also results in silencer vibrations to make a noise, and causes noise elimination effect poor.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of good generators of noise elimination effect
Use muffler.
To achieve the above object, the utility model provides following technical solution：Including be connected air inlet, tube body and
Gas outlet, tube body include interior tube body and outer tube body, and buffer layer is filled between interior tube body and outer tube body, and interior tube body includes connecting successively
Separator tube, enlarged tube and the exhaust pipe connect, exhaust pipe is interior to be equipped with several downtake pipes, and the inner wall of separator tube is equipped with buffering
Baffle, the caliber of enlarged tube are more than the caliber of separator tube, and downtake pipe includes the first nozzle and the second nozzle, the first nozzle and
Enlarged tube is connected, and the second nozzle is connected with gas outlet, and buffer layer is rubber material, and being further opened with several on buffer layer disappears
Sound hole.
Further, distributary division, the spherical shape of distributary division are additionally provided in the cavity of enlarged tube.
Further, several reflection grooves, the spherical shape of reflection groove are additionally provided on cushioning fender.
Further, it is additionally provided with noise reduction cavity on buffer layer, glass fibre cotton is equipped in noise reduction cavity.
The deficiencies in the prior art are compared, advantageous effect caused by technical solution provided by the utility model：When in use,
Air-flow enters separator tube from air inlet, since the presence of cushioning fender makes air-flow when flowing through cushioning fender, fraction punching
Hit cushioning fender so that fraction changes direction, to change the vibration frequency of air-flow, reduces noise, while air-flow is flowing
When to enlarged tube, since the caliber of enlarged tube is more than the caliber of separator tube, when air-flow enters enlarged tube from separator tube, air-flow
Pressure becomes smaller so that the gas diffusion shaken, to achieve the purpose that reduce noise, while the second nozzle of exhaust pipe
Diameter is more than the diameter of the first nozzle, therefore in use, and the gas in enlarged tube can pass through and further subtract in discharge
Pressure reduces gas pulsation, to achieve the purpose that eliminate noise, simultaneously as gas shock interior tube body can lead to interior tube body
Vibrations, therefore buffer layer can reduce the vibrations of interior tube body, avoid because erasure effect caused by the vibrations of interior tube body dies down
The problem of occur, since sound wave is different in solid and spread speed in air, the presence of bloop makes sound wave pass
When being directed at buffer layer, sound wave is divided because movement velocity is different, so that the noise elimination effect of silencer is more preferable.

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
The utility model is described further referring to figs. 1 to Fig. 4.
A kind of generator muffler, including the air inlet, tube body and the gas outlet that are connected, tube body includes 5 He of interior tube body
Outer tube body 6, is filled with buffer layer 4 between interior tube body 5 and outer tube body 6, interior tube body 5 includes sequentially connected separator tube 1, enlarged tube
2 and exhaust pipe 3, several downtake pipes 31 are equipped in exhaust pipe 3, and the inner wall of separator tube 1 is equipped with cushioning fender 11, expands
The caliber of pipe 2 is more than the caliber of separator tube 1, and downtake pipe 31 includes the first nozzle 311 and the second nozzle 312, the first nozzle
311 are connected with enlarged tube 2, and the second nozzle 312 is connected with gas outlet, and buffer layer 4 is rubber material, is also opened on buffer layer 4
Equipped with several bloops 41, bloop 41 is located at 5 side of interior tube body；When in use, air-flow enters separator tube 1 from air inlet,
Since the presence of cushioning fender 11 makes air-flow when flowing through cushioning fender 11, fraction damping of shocks baffle 11 so that portion
Air-flow is divided to change direction, to change the vibration frequency of air-flow, reduction noise, while air-flow when flowing to enlarged tube 2, due to expanding
The caliber of big pipe 2 is more than the caliber of separator tube 1, therefore when air-flow enters enlarged tube 2 from separator tube 1, and stream pressure becomes smaller so that
The gas diffusion shaken, to achieve the purpose that reduce noise, while the diameter of the second nozzle 312 of downtake pipe 31
More than the diameter of the first nozzle 311, therefore in use, the gas in enlarged tube 2 can pass through and further subtract in discharge
Pressure reduces gas pulsation, and is not in contact with each other between downtake pipe 31, and sound wave is reflected in exhaust pipe 3, therefore can be with
Noise is further decreased, to achieve the purpose that eliminate noise, simultaneously as gas shock interior tube body 5 can lead to interior tube body 5
Vibrations, therefore buffer layer 4 can reduce the vibrations of interior tube body 5, avoid because erasure effect becomes caused by the vibrations of interior tube body 5
Weak problem occurs, and since sound wave is different with the spread speed in air in solid, the presence of bloop 41 makes sound wave
When conduction is to buffer layer, sound wave is divided because movement velocity is different, so that the noise elimination effect of silencer is more preferable.
Further, distributary division 21,21 spherical shape of distributary division are additionally provided in the cavity of enlarged tube 2；Air-flow is entering expansion
When pipe 2, gas shock on distributary division 21, gas globally four dissipate so that the vibration frequency of gas is varied so that sound
Phenomena such as reflection and interference, occurs for wave so that noise elimination effect is more preferable.
Further, several reflection grooves 12,12 spherical shape of reflection groove are additionally provided on cushioning fender 11；Therefore it was using
Cheng Zhong, since the presence of the reflection groove 12 of dome shape makes the reflection of sound wave reversely inconsistent so that the interference effect between sound wave
Fruit is more preferable, strengthens erasure effect.
Further, it is additionally provided with noise reduction cavity 42 on buffer layer 4, glass fibre cotton, glass fibre are equipped in noise reduction cavity 42
Cotton is located at outer tube body side, and glass fibre cotton and bloop 41 are staggered, therefore when in use, the sound conducted from buffer layer 4
Wave when glass fibre cotton by further being weakened so that erasure effect is more preferable.
It is worth noting that air inlet and gas outlet are not drawn in the figure.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
