The mute muffler further consists of a first inner pipe and an outer inner pipe, wherein the first inner pipe simultaneously penetrates through the front baffle plate and the back baffle plate for running through the front cavity and the tail cavity, and the second inner pipe penetrates through the back baffle plate for running through the back cavity with the tail cavity.
Description
Technical field
The utility model relates to a kind of quiet silencing apparatus.
Background technique
Silencing apparatus is mainly used in the fields such as motorcycle, automobile, it mainly acts on is to be installed on the waste pipe, the high pressure that motor is discharged, high-speed exhaust gas noise are bigger, do not allow directly to be discharged into waste gas in the air, must carry out noise elimination noise reduction by silencing apparatus handles, though the inner dividing plate that also is provided with of existing silencer cylinder, but directly connect before and after the space in the cylindrical shell, the waste gas that enters silencing apparatus can directly be discharged, less in the inner number of turns that produces of silencing apparatus, noise reduction is not obvious, needs to do further to improve.
Summary of the invention
The purpose of this utility model is to provide a kind of quiet silencing apparatus, the noise that the utility model can effectively be eliminated motor and produced, excellent noise reduction effect.
Its technological scheme is as follows:
A kind of quiet silencing apparatus, comprise cylindrical shell, preceding dividing plate, rear bulkhead and tail pipe, preceding dividing plate, rear bulkhead are located at the rear end of cylindrical shell and cylinder back-end are divided into relatively independent back cavity and tail chamber, the cavity of dividing plate front end is an ante-chamber before in the cylindrical shell, be provided with the suction port that communicates with ante-chamber in barrel front end, tail pipe passes rear bulkhead and cylinder back-end portion simultaneously, and the rear end of tail pipe forms relief opening; This silencing apparatus also includes the first interior pipe, second interior the pipe, and the first interior Guan Tongjin passes preceding dividing plate, rear bulkhead, and the first interior pipe is connected ante-chamber and tail chamber, and the second interior pipe passes rear bulkhead, makes the second interior pipe with back cavity and the perforation of tail chamber.
After waste gas that motor is discharged enters the ante-chamber of silencing apparatus, enter in the tail chamber by the first interior pipe, waste gas in the tail chamber can enter in the back cavity by the second interior pipe, the waste gas of back cavity is discharged in the atmosphere by tail pipe, and the utility model is for existing silencing apparatus, because waste gas fold back repeatedly in silencing apparatus, waste gas is after motor is discharged, its energy is absorbed by silencing apparatus, and the noise that outwards spreads out of by tail pipe is littler, and noise reduction is largely increased.
Further improvement of the utility model is:
On described tail pipe, be provided with vent, described tail chamber communicates with the inside of described tail pipe by this vent, enters the waste gas in the tail chamber, and a part enters in the back cavity by the second interior pipe, some can enter in the tail pipe by vent, discharges by tail pipe again.
Described cylindrical shell comprises main tube and is positioned at the tail-hood of main tube rear end that this tail-hood is passed in the rear end of described tail pipe.Main tube in the cylindrical shell separates with tail-hood makes processing, processes more convenient.
Forward position is arranged with preceding pipe in described cylindrical shell, and described suction port communicates with described ante-chamber by pipe before this.
Be provided with the support dish in described cylindrical shell, the rear end of described preceding pipe is fixed on this support dish.
In described ante-chamber, be provided with the recess dish.
In sum, the utility model has the advantages that: because after waste gas enters silencing apparatus from motor, fold back repeatedly in can silencing apparatus, waste gas at a high speed can collide with the wall of silencing apparatus, its most of energy is absorbed by silencing apparatus, the waste gas that motor is discharged is through after the silencing apparatus, and the noise that outwards spreads out of is littler, the noise reduction ideal.

Embodiment
As shown in Figure 1, a kind of quiet silencing apparatus, comprise cylindrical shell, preceding dividing plate 1, rear bulkhead 2 and tail pipe 3, preceding dividing plate 1, rear bulkhead 2 are located at the rear end of cylindrical shell and cylinder back-end are divided into relatively independent back cavity 4 and tail chamber 5, the cavity of dividing plate 1 front end is an ante-chamber 6 before in the cylindrical shell, be provided with the suction port 7 that communicates with ante-chamber 6 in barrel front end, tail pipe 3 passes rear bulkhead 2 and cylinder back-end portion simultaneously, and the rear end of tail pipe 3 forms relief opening 8; This silencing apparatus also includes in first in the pipe 9, second in the pipe 10, the first pipe 9 with dividing plate 1, rear bulkhead 2 before advancing to pass, and makes that pipe 9 connects ante-chamber 6 and tail chamber 5 in first, and pipe 10 passes rear bulkhead 2 in second, makes that pipe 10 connects back cavity 4 and tail chamber 5 in second.
Wherein, described cylindrical shell comprises main tube 12 and is positioned at the tail-hood 13 of main tube 12 rear ends that this tail-hood 13 is passed in the rear end of tail pipe 3; Be provided with vent 11 on tail pipe 3, tail chamber 5 communicates with the inside of tail pipe 3 by this vent 11; Pipe 14 before forward position is arranged with in cylindrical shell, suction port 7 communicates with ante-chamber 6 by pipe 14 before this; Be provided with in cylindrical shell and support dish 15, the rear end of preceding pipe 14 is fixed on this support dish 15, is provided with recess dish 16 in ante-chamber 6.
After waste gas that motor is discharged enters the ante-chamber 6 of silencing apparatus, enter in the tail chamber 5 by pipe 9 in first, a part of waste gas in the tail chamber 5 can enter in the back cavity 4 by pipe 10 in second, and the waste gas of back cavity 4 is discharged in the atmosphere by tail pipe 3; Another part waste gas that enters in the tail chamber 5 can enter in the tail pipe 3 by vent 11, discharges by tail pipe 3 again.The utility model is for existing silencing apparatus, because waste gas fold back repeatedly in silencing apparatus, waste gas is after motor is discharged, and its energy is absorbed by silencing apparatus, and the noise that outwards spreads out of by tail pipe 3 is littler, and noise reduction is largely increased.
Only be preferred embodiment of the present utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
