Description
Technical field
Guard member technical field is the utility model is related to, more particularly to a kind of expanding muffler.
Background technology
Noise is the byproduct that industrial society's fast development is brought, it is considered together with atmosphere pollution and water pollution
It is three big public hazards of the world today.As the improvement of people's living standards, automobile becomes increasingly popular and increases as a kind of vehicles,
Environmental pollution getting worse caused by automobile noise, therefore the harm that research automobile noise, reduction automobile noise are brought becomes
One problem urgently to be resolved hurrily.
Gas handling system can regard the system being made of some pipelines and acoustics original paper (or being silencer element) as.Mesh
Before, silencer element includes expanding muffler, Hull nurse hereby muffler, quarter-wave long tube etc..In gas handling system, expansion
Formula muffler is also at the same time air filter, and expanding muffler plays very important for the gas handling system noise reduction of vehicle
Effect.
A key factor for influencing expanding muffler erasure effect is exactly divergence ratio, can be by improving divergence ratio
Method improves erasure effect, and to increase the approach of divergence ratio have two, otherwise the sectional area of increase expansion cavity, otherwise reduce pipeline
Sectional area.But the sectional area of the sectional area of increase expansion cavity or reduction pipeline is all conditional.In air inlet system and exhaust system
In, the sectional area for increasing expander suffers from the limitation of installation space, and the sectional area for reducing pipeline influences whether air-flow
Circulation.When sectional area is too small, if the speed of air-flow is too fast, frictional noise very high on duct wall can be caused.
Therefore, a kind of neither influence installation and the expanding muffler with good noise elimination effect how are designed, is this
Field technology personnel's urgent problem.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of expanding muffler, and appearance is light,
Occupied space is smaller, and does not influence noise elimination effect；
Further, the utility model uses following technical proposals：
A kind of expanding muffler, including expansion chambers, expansion chambers one end are connected with air inlet pipe, the expansion chambers other end and outlet
Pipe connects；
The expansion chambers are separated into the first chamber and the second chamber by partition plate, and first chamber and the second chamber are connected by connecting tube
It is logical；The outlet side of the connecting tube is obliquely installed, and the central axes of outlet end section and expansion chambers are in setting angle.
Further, the outlet side of the connecting tube is arranged to curve bend.So set, be conducive to the smooth stream of air-flow
It is logical
Further, the outlet end opening of the connecting tube is tilted towards air outlet pipe.
Preferably, the connecting tube sets two, and the outlet side of two connecting tubes is oppositely arranged.
Further, the angle of two connecting tube outlet end sections is 20~40 degree.
Further, first chamber is connected with air inlet pipe, and the second chamber is connected with air outlet pipe.
Further, the volume of first chamber is less than the volume of the second chamber.
Further, the inlet end of the connecting tube is connected with the first chamber, and the outlet side of connecting tube is connected with the second chamber.
Compared with prior art, the beneficial effects of the utility model are：
The muffler of the utility model, by being arranged to the connecting tube outlet side of two chamber of expansion chambers with central axes in setting
Angle, under conditions of air inlet open area is certain, increases the area of gas outlet, and then increases divergence ratio.
The muffler of the utility model will not take exceptional space, occupy little space, and ensure that silencer in limited peace
The erasure effect of silencer is improved on the premise of dress space.

Meaning property embodiment and its explanation are used to explain the application, do not form the improper restriction to the application.
Fig. 1 is the muffler structure schematic diagram of the utility model；
Fig. 2 is the muffler axonometric drawing of the utility model；
In figure, 1 air outlet pipe, 2 expansion chambers, 3 connecting tubes, 4 partition plates, 5 air inlet pipe, 6 first chambers, 7 second chambers.
Embodiment
It is noted that described further below is all illustrative, it is intended to provides further instruction to the application.It is unless another
Indicate, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
As background technology is introduced, otherwise lifting muffler effect needs to increase the section of expansion cavity in the prior art
Accumulate and then can not effectively install, otherwise need to reduce the sectional area of pipeline and then influence airflow；For depositing in the prior art
The deficiency of noise elimination effect can not be improved in the confined space in muffler, present applicant proposes a kind of expanding muffler.
In a kind of typical embodiment of the application, as shown in Figure 1, there is provided a kind of expanding muffler, including expand
Room 2 is opened, as shown in Fig. 2, expansion chambers 2 are cylindrical shape, 2 one end of expansion chambers is connected with air inlet pipe 5,2 other end of expansion chambers and outlet
Pipe 1 connects；
Expansion chambers 2 are separated into the first chamber 6 and the second chamber 7 by partition plate 4, and the first chamber 6 is connected with the second chamber 7 by connecting tube 3；
First chamber 6 is connected with air inlet pipe 5, and the second chamber 7 is connected with air outlet pipe 1.The volume of first chamber 6 is less than the volume of the second chamber 7, ensures
The noise elimination effect of muffler.
