Abstract

The utility model discloses a vehicle vent -pipe muffler, including bobbin, resonant chamber, anechoic room, intake pipe and outlet duct, the bobbin is inside to be divided into the anechoic room between resonant chamber and the resonant chamber by first baffle and second baffle, first baffle had all been opened the tube hole with second baffle top layer and had been crossed the tube hole outside and had been equipped with the micropunch and evenly distributed, intake pipe one end pierces into the tube hole of crossing of bobbin and first baffle and is connected with the second baffle, the tube hole of crossing that bobbin and second baffle were passed to outlet duct one end stretches into in the anechoic room, the abatvoix is equipped with the abatvoix in the anechoic room and being located between intake pipe and the outlet duct, the anechoic room intussuseption is filled with acoustical coating, and this muffler noise cancelling effect is good, the reduction of very big degree noise pollution to inside gas flow is good for the muffler, can not produce the backward flow, has improved automobile engine's output, and simple structure is just with production and use.

Description

A kind of automobile exhaust pipe deafener

【Technical field】

This utility model relates to a kind of deafener, particularly to a kind of automobile exhaust pipe deafener.

【Background technology】

The muffler of automobile is used to reduce a critical component of automobile engine to exhaust noise, it eliminates noise by the pulsation of reduction, decay pressure at expulsion, existing muffler structure is complicated, manufacturing technique requirent is high, there is the problem that erasure effect is bad, to this end, it is proposed that a kind of automobile exhaust pipe deafener.

【Utility model content】

Main purpose of the present utility model is to provide a kind of automobile exhaust pipe deafener, can effectively solve the problem in background technology.

For achieving the above object, the technical scheme that this utility model is taked is:

A kind of automobile exhaust pipe deafener, including socket, resonant chamber, anechoic chamber, air inlet pipe and escape pipe, it is divided into the anechoic chamber between resonant chamber and resonant chamber by the first dividing plate and second partition inside described socket, described first dividing plate and second partition top layer all had outside pore and mistake pore and are provided with micropunch and are uniformly distributed, described air inlet pipe one end is pierced into the pore of crossing of socket and the first dividing plate and is connected with second partition, described escape pipe one end extend in anechoic chamber through the pore of crossing of socket and second partition, abatvoix and abatvoix it is provided with between air inlet pipe and escape pipe in described anechoic chamber, it is filled with quieter material in described anechoic chamber.

Further, described quieter material is gradient acoustical cotton.

Further, the air inlet pipe end in described anechoic chamber and top layer, exhaustor end have air dispelling hole.

Further, described abatvoix is fixing with tube walls, the first dividing plate and the first dividing plate respectively is connected.

Further, described abatvoix top layer is provided with air passing hole.

Compared with prior art, this utility model has the advantages that a kind of automobile exhaust pipe deafener, this deafener good muffling effect, high degree reduce noise pollution, and deafener internal gas flow is good, will not produce backflow, improve the output of automobile engine, simple in construction, just with production and use.

【Detailed description of the invention】

For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, this utility model is expanded on further.

As Figure 1-3, a kind of automobile exhaust pipe deafener, including socket 2, resonant chamber 5, anechoic chamber 7, air inlet pipe 1 and escape pipe 9, described socket 2 is internal is divided into the anechoic chamber 7 between resonant chamber 5 and resonant chamber 5 by the first dividing plate 6 and second partition 4, described first dividing plate 6 and second partition 4 top layer all had outside pore 12 and mistake pore 12 and are provided with micropunch 10 and are uniformly distributed, described air inlet pipe 1 one end is pierced into the pore 12 of crossing of socket 2 and the first dividing plate 6 and is connected with second partition 4, described escape pipe 9 one end extend in anechoic chamber 7 through the pore 12 of crossing of socket 2 and second partition 4, abatvoix 8 and abatvoix 8 it is provided with between air inlet pipe 1 and escape pipe 9 in described anechoic chamber 7, it is filled with quieter material 13 in described anechoic chamber 7.

This utility model automobile exhaust pipe deafener, gas enters air inlet pipe 1 and is entered into inside, anechoic chamber 7 by air dispelling hole 3, gas reduces the undulatory property of gas through the space of quieter material 13, anechoic chamber 7 also plays the effect of expanding gas simultaneously, further function as the effect reducing noise, gas both sides resonant chamber 5 while socket 2 internal flow serves good eliminating gas heat energy and subtract the effect of sound, and then gas is discharged through abatvoix 8 by escape pipe 9.

Wherein, described quieter material 13 is gradient acoustical cotton, and material internal space connects so that gas fluidity is good, sound-absorbing effect is good.

Wherein, air inlet pipe 1 end in described anechoic chamber 7 and top layer, exhaustor end have air dispelling hole 3.

Wherein, described abatvoix 8 is fixed be connected with socket 2 inwall, the first dividing plate 6 and the first dividing plate 6 respectively.

Wherein, described abatvoix 8 top layer is provided with air passing hole 11.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
