Description
Technical field
This utility model belongs to technical field of automobile, more specifically, it relates to a kind of sound eliminator for automobile with Intelligent drainage device.
Background technology
Be higher than bottom deafener for the position of exhaust tail pipe of automobile Yu deafener junction, cause the partial tail gas discharged to condense into water, after water accumulates in deafener, not only can corrode deafener, and weather turn cold in the case of can congeal into ice, blocking deafener.Affecting normal vehicle operation, be at present the water accumulated in exhaust silencer, general use minimum point punching and siphon mode, although the former drainability is relatively strong, but to corrode meeting near osculum more serious for muffler shell external surface.For the latter, owing to siphon needs bigger pressure differential, can be only achieved drainage effect.So under conditions of vehicle low cruise, siphon functional hole can lose efficacy.Discharge from discharge outlet additionally, both have substantial amounts of tail gas while draining, so, not only increase noise, reduce the erasure effect of deafener, and make tail gas not discharge by fixed course, cause chassis to pollute.
Summary of the invention
In order to overcome above-mentioned technical problem, this utility model provides a kind of sound eliminator for automobile with Intelligent drainage device.
This utility model is realized by following technical proposals:
A kind of sound eliminator for automobile with Intelligent drainage device, including deafener body, tail gas air inlet pipe, tail gas escape pipe, shell body and drain pipe, above-mentioned deafener body is cydariform, the outside of deafener body is provided with shell body, above-mentioned tail gas air inlet pipe is fixedly connected on the air inlet side of deafener body, above-mentioned tail gas escape pipe fix be connected in deafener body give vent to anger on side, above-mentioned tail gas air inlet pipe is equal with the aperture area of above-mentioned tail gas escape pipe, above-mentioned deafener body position lowest part is provided with drain pipe, above-mentioned deafener is the most internal is sequentially provided with defecator by tail gas air inlet pipe to the direction of tail gas escape pipe, part flow arrangement and silencing means, above-mentioned defecator, suppressor lumen is divided into four parts by part flow arrangement and silencing means, chamber I, chamber II, chamber III and chamber IV.
Preferably, above-mentioned defecator is drainage screen.
Preferably, above-mentioned part flow arrangement includes silencing baffles I, distributing damper and connecting plate, and above-mentioned silencing baffles I is loudspeaker tubular, and above-mentioned connecting plate is cylindrical, and above-mentioned distributing damper is cone, and above-mentioned silencing baffles I is connected with distributing damper by connecting plate.
It is more highly preferred to, above-mentioned silencing baffles I is provided with some air-vents I, on above-mentioned silencing baffles I, the perforated area summation of all air-vents I is equal with the aperture area of above-mentioned tail gas air inlet, it is ensured that silencing baffles I is provided with air-vent I with the extreme lower position of deafener body junction.
Particularly, above-mentioned silencing means is silencing baffles II, above-mentioned silencing baffles II is provided with some air-vents II, on above-mentioned silencing baffles II, the perforated area summation of all air-vents II is equal with the aperture area of above-mentioned tail gas air inlet, it is ensured that silencing baffles II is provided with air-vent II with the extreme lower position of deafener body junction.
More particularly, the gap between above-mentioned deafener body and shell body is 3-5mm, is filled with silencing cotton in above-mentioned gap.
Wherein, above-mentioned drain valve is provided with the normally closed solenoid valve of band check function, and above-mentioned electromagnetic valve is by control unit of engine control, and in 60 seconds after design engine misses, electromagnetic valve can automatically open up, and water is discharged by drain pipe.
Silencing baffles I is 60 ° with the angle of deafener body.
Deafener body has the plane of two non-curved, and one of them is designated as A-A ' is air inlet side, and another is designated as B-B ' for side of giving vent to anger.
The beneficial effects of the utility model are: this internal defecator that is provided with of deafener, part flow arrangement and silencing means, can not only filter out granule in tail gas, and silencing baffles is provided with air-vent,
When tail gas passes through the air-vent on silencing baffles, owing to vent diameter is less, the frequency spectrum of noise in tail gas can be converted to high frequency or hyperfrequency, thus reduce the composition of audible noise in tail gas, meanwhile, on dividing plate, the perforated area summation of air-vent is equal with the aperture area of described air inlet, and tail gas can be made when stream passes through on dividing plate, ensure that overall flow velocity is constant, preferably realize the noise reduction to exhaust noise by adjustment air-vent size.
Electromagnetic valve is controlled by control unit of engine, when in 60 seconds after engine misses, electromagnetic valve automatically opens up draining, avoid substantial amounts of tail gas while draining to discharge from osculum, ensure that the erasure effect of deafener, also make tail gas discharge by the route of regulation simultaneously, use the electromagnetic valve of band check function, it is to avoid external water pours in down a chimney into deafener.
This utility model alleviates because the hydrops corrosiveness to deafener while ensureing noise reduction, extends the service life of deafener, and its simple in construction, and with low cost, effect is obvious.
