Description
Technical field
This utility model is related to a kind of apparatus of the internal-combustion engine technical field, more particularly to a kind of automobile exhaust muffler.
Background technology
Acoustic filter is to allow air-flow to pass through, but can prevent or reduce a kind of device of sound transmission, is to eliminate air to move
The important measures of power noise, acoustic filter can stop the propagation of sound wave, it is allowed to which air-flow passes through, and be the effective work for controlling noise
Tool, existing acoustic filter mostly adopt impedance composite noise-cancelling theory, as complex structure, weight are big, high-temperature oxydation sound absorption is filled out
Material, high velocity air impact the reasons such as sound absorption filler, aqueous vapor infiltration sound absorption filler, and acoustic filter is easy to occur keeping in repair frequently, eliminates the noise
Effect is poor, situations such as usage cycles are short.
A kind of Chinese patent of Publication No. CN204663629U, and in particular to New Buffering impedance type deafener, including
Expansion anechoic chamber, the one end for expanding anechoic chamber are provided with air inlet pipe, and its other end is provided with escape pipe, in expansion noise reduction room and air inlet
The face of the central axis of pipe is provided with dividing plate, and V-arrangement buffer board is provided between dividing plate and air inlet, and dividing plate is provided with insertion tube,
Insertion tube is provided with and shock absorbing hole and subtracts discharge orifice, is additionally provided with sound absorbing layer on insertion tube, insertion tube and air inlet pipe and expands anechoic chamber
Centrage is identical, and expansion is provided with four groups of dividing plates in noise reduction room, and every group of dividing plate has four pieces, is equipped with insertion tube on four pieces of dividing plates, and four
Expansion anechoic chamber is divided into four identical sector shaped chambers centered on the centrage for expanding anechoic chamber by block dividing plate, the dividing plate with
Stiffening ring is provided between expansion noise reduction chamber interior walls.
Although the acoustic filter, its simple structure, is widely used, can be absorbed according to the high and low frequency in noise respectively
Noise reduction, but automobile exhaust dress in acoustic filter can not realize in same exhaust apparatus in line drum and back pressure drum function with
Little as noise reduction resistance, erasure effect is not clear to be thought, also improved space.
Utility model content
The purpose of this utility model is to provide a kind of automobile exhaust muffler, can effectively improve erasure effect.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of automobile exhaust muffler, including housing and silencers channel, the two ends of the housing are equipped with baffle plate, described to disappear
Sound passage is penetrated from the side of plate washer, and the silencers channel is projected from the opposite side of baffle plate and extends to the outside of housing, institute
State silencers channel circular first bloop is equipped with enclosure interior.
Using such scheme, as silencers channel is that one end is input into, other end output represents silencers channel through housing,
As silencers channel is equipped with bloop in enclosure interior, bloop itself can effectively reduce the sound of input input, pass through
The sound of input is reduced, the erasure effect of silencers channel can be effectively improved.
Preferably, the enclosure interior is provided with first sound-absorbing layer that disappears for wrapping silencers channel.
Using such scheme, as enclosure interior is equipped with noise reduction layer, as noise reduction layer itself has the energy for absorbing noise
Power, when the noise on silencers channel is spread out of by bloop to be come, can effectively realize absorbing the noise on silencers channel, enter one
Step reduces noise.
Preferably, first noise reduction layer includes silk screen, silk floss, high temperature cotton, high temperature cotton contradicts and is connected to silencers channel,
The silk flosssilk wadding is fixedly connected on side of the high temperature cotton away from silencers channel, and the silk screen is fixedly connected on silk floss away from high temperature cotton
Side.
Using such scheme, as silk screen has the ability of conduction noise, and silk floss and high temperature cotton itself all have noise reduction
Ability, and high temperature is continuous itself even possesses heat-insulated ability, can more effectively reduce silencers channel temperature operationally, pass through
Silk screen and silk floss, high temperature cotton.
Preferably, the silencers channel includes the first hush pipe, the second hush pipe, the first bend pipe, the second bend pipe, it is described
First hush pipe, the second hush pipe are arranged at enclosure interior, and first bend pipe is communicated in the first hush pipe, and described second is curved
Pipe is communicated in the second hush pipe.
Using such scheme, as silencers channel repeatedly passes through housing, once, can only pass through to disappear compared to just through housing
Sound-absorbing layer carries out preliminary noise reduction, and repeatedly passes through housing, by cooperating for bloop and noise reduction layer, can further reduce and make an uproar
Sound.
Preferably, first hush pipe and the second hush pipe are not overlapped each other and leave gap.
Using such scheme, as silencers channel does not overlap and leaves each other gap in housing, and the gap base
Originally completely cut off with noise reduction layer, can be prevented effectively from by above-mentioned setting overlapped so that the reduction of erasure effect.
Preferably, the silencers channel is provided with the cross section of input port and delivery outlet and the input port and delivery outlet
It is circle.
Using such scheme, due to doing the circular volume and circle that can have the minimum material of realization to obtain maximum itself
With the ability for strengthening resistance to pressure, by above-mentioned setting, resistance to pressure can be significantly reduced costs and can be strengthened, noise can be prevented effectively from
It is excessive to produce the excessive phenomenon of pressure.
Preferably, the delivery outlet on the silencers channel is more than the diameter of input port.
Using such scheme, the diameter of delivery outlet is set greater than the diameter of input port here, effectively noise reduction can be led to
Road can be effectively increased area in last delivery outlet increase delivery outlet defeated to reduce unit after in the noise elimination process of enclosure interior
Go out noise, reduce the unit effect of noise.
In sum, this utility model has the advantages that：
1st, the bloop for being arranged in enclosure interior by silencers channel and the noise reduction layer for being arranged at enclosure interior, can be effectively real
Now noise is reduced；
2nd, do not overlap each other and leave gap by the first hush pipe and the second hush pipe, be avoided that each other
Affect, further improve soundproof effect；
3rd, the sound of last output effectively can be carried out by unit area by the diameter with diameter greater than input port of delivery outlet
The reduction of formula is realizing noise reduction on general effect.
