Description
Technical field
This utility model is related to vehicle muffling device technical field, more particularly to a kind of automotive muffler.
Background technology
At present, loud noise is sent during automobile engine to exhaust, typically, can connect a noise elimination on waste pipe
Device, to reduce exhaust noise, but, as the temperature on automotive muffler is higher, temperature is higher to be just directly discharged in air
Waste is easily caused, on the other hand, other positions of automobile are also required to such high-temperature, and acoustic filter of the prior art is only
Can play reduces the purpose of noise.
Therefore, there is the technical problem of automotive muffler single function in prior art.
Utility model content
This utility model embodiment provides a kind of automotive muffler, solves
The single technical problem of energy.
In order to solve above-mentioned technical problem, this utility model embodiment provides a kind of automotive muffler, disappears including outer layer
Sound plate housing and internal layer noise elimination housing, the outer layer noise elimination housing are coated in nested with the internal layer noise elimination housing, described outer
Acoustical cotton and circulating water pipe are provided between layer noise elimination housing and the internal layer noise elimination housing, the automotive muffler also includes
Air inlet pipe and escape pipe, described air inlet pipe one end are connected to vehicle-exhaust exhaust pipe, and the other end is connected to the internal layer noise elimination shell
Body, the escape pipe are connected on the internal layer noise elimination housing with the air inlet pipe relative misalignment, in the internal layer noise elimination housing
Inside it is divided into three chambers, is followed successively by the first expansion chamber, pressure release chamber, the second expansion chamber, it is swollen that the air inlet pipe enters first
Swollen chamber, the escape pipe stretch into the second expansion chamber, and the gas enters the first expansion chamber, through pressure release chamber, then
Flow out through the second expansion chamber.
Further, multiple steam vents are provided with the air inlet pipe other end.
Further, first expansion chamber, pressure release chamber, the second expansion chamber pass sequentially through baffle connection.
This utility model embodiment at least has the following technical effect that or advantage：
Due to adopting outer layer muffler plate housing and internal layer muffler plate housing, and the outer layer muffler plate in the automotive muffler
Housing cladding nested with internal layer muffler plate housing, is provided with acoustical cotton between outer layer muffler plate housing and internal layer muffler plate housing
And circulating water pipe, the automotive muffler also includes air inlet pipe, escape pipe, and air inlet pipe one end is connected to vehicle exhaust aerofluxuss
Pipe, the other end are connected to internal layer muffler plate housing, are divided into three chambers, are followed successively by the first expansion chamber in internal layer muffler plate housing
Room, pressure release chamber, the second expansion chamber, tail gas enter the first expansion chamber, through pressure release chamber, then through the second expansion chamber
Flow out, solve the technical problem that there is automotive muffler single function in prior art, and then while acoustic filter is eliminated the noise,
Tail gas can be lowered the temperature, be reduced the hot driving of automobile.
Description of the drawings
Fig. 1 is the structural representation of automotive muffler in this utility model embodiment.
Specific embodiment
This utility model embodiment is solved by providing a kind of automotive muffler
The technical problem of single function.
In order to solve above-mentioned technical problem, below in conjunction with Figure of description and specific embodiment to above-mentioned technology
Scheme is described in detail.
A kind of automotive muffler that this utility model is provided, as shown in figure 1, disappear including outer layer muffler plate housing 10 and internal layer
Sound plate housing 20, the outer layer muffler plate housing 10 are coated in nested with the internal layer muffler plate housing 20, in outer layer muffler plate housing
Acoustical cotton 30 and circulating water pipe 40 is provided between 10 and internal layer muffler plate housing 20, and the automotive muffler also includes air inlet pipe
50 and escape pipe 60,50 one end of air inlet pipe is connected to vehicle-exhaust exhaust pipe, and the other end is connected to internal layer muffler plate housing 20
Interior, the escape pipe 60 is with 50 relative misalignment of air inlet pipe and the escape pipe 60 is connected on internal layer muffler plate housing 20, in the internal layer
It is divided into three chambers in muffler plate housing 20, is followed successively by the first expansion chamber 201, pressure release chamber 202, the second expansion chamber 203,
The air inlet pipe 50 enters first expansion chamber 201, and the escape pipe 60 stretches into the second expansion chamber 203, and so, gas enters the
One expansion chamber 201, through pressure release chamber 202, most flows out through the second expansion chamber 203 afterwards, so when gas is in the first expansion
Chamber 201, pressure release is asked the 202, second expansion chamber 203 for instructions and reflects successively, interferes etc., carries out noise reduction process, finally exports, at this
During, 40 pairs of tail gas of circulating water pipe are lowered the temperature, so as to reduce the hot driving of automobile.
The air inlet pipe 50 is stretched into and is provided with multiple steam vents on one end of internal layer muffler plate housing 20, and such tail gas is entered should
When in internal layer muffler plate housing 20, can be by the gas of multi-direction entrance.
Baffle connection is passed sequentially through in first expansion chamber 201, pressure release chamber 202, the second expansion chamber 203, from
And can also carry out filtering noise.
Although having been described for preferred embodiment of the present utility model, those skilled in the art once know substantially
Creative concept, then can make other change and modification to these embodiments.So, claims are intended to be construed to wrap
Include preferred embodiment and fall into the had altered of this utility model scope and change.
