Abstract
The invention discloses an automatic drainage silencer for a vehicle. The automatic drainage silencer comprises a shell, a front stop plate and a rear stop plate are arranged inside the shell and divide the shell into a front cavity, a middle cavity and a rear cavity, an air inlet tube spans the front cavity and the middle cavity to be erected on the front stop plate and the rear stop plate, and an air outlet tube spans the rear cavity and the middle cavity to be erected on the rear stop plate and the front stop plate. The automatic drainage silencer further comprises a siphon. A Venturi tube is arranged in the middle of the air outlet tube, and the siphon is connected to the position, with the smallest caliber, of the Venturi tube and communicated with the Venturi tube. Compared with the prior art, the automatic drainage silencer has the advantages of being high in drainage performance, good in corrosion resistance and low in cost, and is suitable for improving the overall condensed-water drainage effect, and therefore the corrosion resistance of the automatic drainage silencer is improved.
Description
Technical field
The present invention relates to a kind of silencer for automobile, particularly a kind of automobile-used Auto-drainage baffler.
Background technique
At present, in automobile exhaust muffler, for reaching antiseptic property, be generally to adopt the mode of syphon tube or the punching of housing minimum point to carry out condensed water discharge.For the former, because syphon tube needs larger pressure difference, just can reach drainage effect, so under the lower condition of city driving running velocity, simple design of siphon pipes will lose efficacy, cause the silencing apparatus aqueous corrosion that is condensed; Although the latter's drainage capacity is stronger, suppressor case outer surface corrodes near weep hole can be more serious, affects outward appearance; In vent design, when vehicle idling, condensed water also can be discharged in addition, thereby causes the ground at the parked place of vehicle to there will be ponding.
Summary of the invention
Object of the present invention, is the deficiency existing in order to overcome above-mentioned prior art, provides a kind of vehicle low speed drainage performance good, corrosion resistant automobile-used Auto-drainage baffler.
To achieve these goals, the present invention has adopted following technological scheme: a kind of automobile-used Auto-drainage baffler, comprise housing, in housing, be provided with front screen, backboard, front screen and backboard are separated into ante-chamber, lumen and back cavity by housing, one suction tude is crossed over ante-chamber and lumen is erected on front screen and backboard, and a steam outlet pipe is crossed over back cavity and lumen is erected on backboard and front screen; Also comprise syphon tube; In the middle of described steam outlet pipe, be provided with one section of Venturi tube, described syphon tube is connected to the bore minimum position of Venturi tube and is communicated with Venturi tube.
Described Venturi tube is arranged in the middle of the steam outlet pipe that is positioned at housing back cavity.
Described syphon tube is connected to the below of Venturi tube and the base plate that siphon port approaches housing down.
Described front screen and backboard are perforated baffle.
Compared with prior art, the present invention has the following advantages:
One, owing to being provided with one section of Venturi tube and syphon tube has been installed in the middle of steam outlet pipe, greatly improve vehicle low speed drainage performance, thereby the decay resistance of silencing apparatus is improved, improved the life-span of silencing apparatus;
Two, due to condensed water, by suppressor case, do not discharge but take out of by steam outlet pipe, the outer surface of suppressor case can not contact with condensed water, has avoided the corrosion of outer surface, has guaranteed appearance looks elegant;
Three, in the time of avoiding vehicle idling parked due to this structure, discharge condensed water, accumulate in ground, thereby also protected the environmental hygiene at the parked place of idling;
Four, only need increase a changes of section at muffler outlet piper, construct a Venturi tube, simple in structure, cost is reasonable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the automobile-used Auto-drainage baffler of the present invention.
Embodiment
Referring to Fig. 1, automobile-used Auto-drainage baffler of the present invention, comprise housing 1, in housing, be provided with front screen 2, backboard 3, front screen 2 and backboard 3 are separated into ante-chamber 11, lumen 12 and back cavity 13 by housing, one suction tude 4 crosses over ante-chamber and lumen is erected on front screen and backboard, and a steam outlet pipe 5 crosses over back cavity and lumen is erected on backboard and front screen; Also comprise syphon tube 6, in the middle of steam outlet pipe 5, be provided with one section of Venturi tube 51, this Venturi tube 51 is arranged in the middle of the steam outlet pipe that is positioned at housing back cavity 13.Syphon tube 6 is connected to the below of bore minimum position of Venturi tube 51 and the base plate that siphon port approaches housing down.
The working principle of automobile-used Auto-drainage baffler of the present invention is, air-flow and noise through suction tude, first enter back cavity, then from back cavity, turn back and enter lumen through backboard, after lumen noise reduction, from front screen, out enter ante-chamber again, from ante-chamber, turn back and enter steam outlet pipe again, by steam outlet pipe, discharged.The condensed water accumulating in housing sucks Venturi tube by syphon tube, and then discharges with air-flow from steam outlet pipe.During common automobile low cruise, exhaust airstream flow velocity is less, general silencing apparatus is difficult to condensed water effectively to discharge, and in the present invention, Venturi tube on steam outlet pipe can make low speed flow accelerate, and utilizes the air-flow after accelerating to produce higher negative pressure, and the position of flow velocity maximum in Venturi tube just in time, siphonal position, thereby promote the drainage effect of silencing apparatus under vehicle low cruise operating mode, improve the decay resistance of silencing apparatus.
Claims (4)
