Description
Technical field
The utility model relates to auto parts field, particularly relates to a kind of automobile exhaust pipe multifunctional silencer.
Background technique
Automobile is city main noise pollution sources, and the exhaust sound of motor is again the main source of automobile noise.Current noise problem will be subject to more attention after emission problem, and correlated noise mandatory standard was implemented already, and have progressively strict trend.The effect of mobile muffler is the noise reducing motor generation, reduces vibration, improves the travelling comfort protection of the environment that automobile uses.Existing baffler comprises enclosing housing and is connected to suction tude (i.e. the outlet pipe of automobile) and the steam outlet pipe at enclosing housing two ends, is provided with silencing board, silencing board is distributed with bloop of collaborating in enclosing housing.The waste gas of discharging after engine combustion is entered in enclosing housing by suction tude, and after passing through the noise reduction of collaborating of extended volume and silencing board in enclosing housing, reaches the effect of step-down, noise elimination, finally discharged by steam outlet pipe.The gas entered in enclosing housing due to the suction tude in baffler finally all outwardly will be discharged by steam outlet pipe, but because exhaust port arranges single and discharge area is less than normal, it is unobstructed that inner exhaust passage is arranged so that air-flow is difficult to, this just will inevitably cause the exhaust of steam outlet pipe not smooth, the exhaust resistance of baffler is strengthened, and the back pressure required for motor is reduced, simultaneously because the gas of motor discharge is with partial impurities, need to regularly replace baffler, spend high.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of automobile exhaust pipe multifunctional silencer.
The utility model is achieved through the following technical solutions:
A kind of automobile exhaust pipe multifunctional silencer, comprise tank body, suction port, the propagation chamber being arranged on described tank interior, the dividing plate that is disposed adjacent with described propagation chamber, the described suction port place of described tank body has been threaded front shroud, described suction port place is provided with filter layer, described dividing plate is provided with air pipe, the other end of described air pipe is arranged on rear end cover, and the described tank body of described air pipe surrounding is provided with noise reduction layer.
As optimal technical scheme of the present utility model, described air pipe is evenly equipped with vent.
As optimal technical scheme of the present utility model, described dividing plate is provided with trapezoidal inlet hole.
As optimal technical scheme of the present utility model, the material glass fiber filter of described filter layer is cotton.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, structure is simple, inlet hole is provided with the impurity contained in filter blocks tail gas and enters baffler, tail gas enters rear first gathering after diffusion, decrease the momentum of tail gas, the trapezoidal design of suction port during gathering makes gas circulate gently, thus prevent because excessive change makes gas block, it is smooth-going that the uniform vent in air pipe surface makes gas circulate, it is little that the multilayer sound-silencing measures arranged makes tail gas contain momentum, has good erasure effect.Front and rear cover plate easily can be opened and clean baffler inside simultaneously, succinctly easy to operate, need not change baffler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-suction port; 2-front shroud; 3-filter layer; 4-propagation chamber; 5-dividing plate; 6-noise reduction layer; 7-rear end cover; 8-air pipe; 9-tank body.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of automobile exhaust pipe multifunctional silencer, comprise tank body 9, suction port 1, the propagation chamber 4 being arranged on described tank body 9 inside, the dividing plate 5 that is disposed adjacent with described propagation chamber 4, described suction port 1 place of described tank body 9 has been threaded front shroud 2, described suction port 1 place is provided with filter layer 3, described dividing plate 5 is provided with air pipe 8, the other end of described air pipe 8 is arranged on rear end cover 7, and the described tank body 9 of described air pipe 8 surrounding is provided with noise reduction layer 6.Described air pipe 8 is evenly equipped with vent.Described dividing plate 5 is provided with trapezoidal inlet hole.Inlet hole is provided with the impurity contained in filter blocks tail gas and enters baffler, tail gas enters rear first gathering after diffusion, decrease the momentum of tail gas, the trapezoidal design of suction port during gathering makes gas circulate gently, thus prevent because excessive change makes gas block, it is smooth-going that the uniform vent in air pipe 8 surface makes gas circulate, and the multilayer sound-silencing measures of setting makes tail gas contain momentum seldom, has good erasure effect.Front and rear cover plate can easily be opened simultaneously, cleans baffler inside, succinctly easy to operate, need not change baffler.
The material glass fiber filter of described filter layer 3 is cotton, high temperature resistant, easily cleans.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
