Description
[technical field]
This utility model relates to acoustic filter technical field, particularly to a kind of automobile exhaust muffler.
[background technology]
The process of car exhaust pipes waste gas and the aperture of throttle have relation, when accelerator open degree is bigger, and gasoline combustion
More and produce bigger power with discharge exhausted air quantity.And when accelerator open degree is less, gasoline combustion is less and produces less dynamic
Power and discharge exhausted air quantity.When oiling is accelerated, exhaustor is full of waste gas to be discharged, but when oil return, often results in extraneous cold sky
Gas is entered by exhaustor tail pipe, if a large amount of cold air moment enters exhaustor, the temperature within exhaustor can be made suddenly to drop and shape
Become part of condensed liquid.And when refueling, the discharge the most easily affecting waste gas is smooth, produce phenomenon of detonation.Therefore, there are many aerofluxuss
Pipe be designed with multiple different bending and inflection path, on the one hand except Exhaust Pressure and the volume of can decaying, on the other hand
Also extraneous substantial amounts of cold air transient backflow is reduced to inside exhaustor.But, most exhaustor the most only considers aerofluxus
The limit in path, does not considers that the waste gas produced because of limit excessively squeezes the aerofluxus that phenomenon caused smooth, and may be because of
Aerofluxus has some setbacks produced noise problem.To this end, it is proposed that a kind of automobile exhaust muffler.
[utility model content]
Main purpose of the present utility model is to provide a kind of automobile exhaust muffler, filters by being provided with toxic gas
Device, acoustic board and high-frequency tube, sound can first be absorbed and small and exquisite be easily installed, on two high-frequency tubes by acoustic board
Sound can be eliminated by intensive through hole, the installation of toxic gas filter, and can effectively remove has poison in air
Body, compares environmental protection, and noise elimination from level to level can obtain good soundproof effect, 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 muffler, including cylinder
Body, entering trachea, escape pipe and the first high-frequency tube, described inner barrel is provided with the first dividing plate and second partition, described cylinder side
Being provided with air intake and opposite side is provided with gas outlet, described air intake is connected by entering trachea and the first dividing plate, described in enter gas

Cross escape pipe to be connected with second partition, be provided with screw rod inside described escape pipe and screw rod upper surface is provided with flight.
Further, described cylinder upper and lower surface is provided with cushion, and described inner barrel is provided with exhalant canal.
Further, described cylinder, the first dividing plate and second partition material are all sound-absorbing material.
Further, described inner barrel is provided with the second high-frequency tube, described second high-frequency tube the first high-frequency tube just under
Side.
Further, described toxic gas filter is provided with three layers of filter course being close to.
Compared with prior art, this utility model has the advantages that this utility model is by being provided with toxic gas
Filter, acoustic board and high-frequency tube, sound can first be absorbed and small and exquisite be easily installed by acoustic board, two high-frequency tubes
On intensive through hole sound can be eliminated, the installation of toxic gas filter, can effectively remove having in air
Poisonous gas, compares environmental protection, and noise elimination from level to level can obtain good soundproof effect.
