Abstract
An automobile muffler capable of discharging condensed water relates to an automobile sound deadening exhaust system and is used for resolving the problem that service life of an existing muffler is affected due to the fact that condensed water corrodes muffler materials. The automobile muffler comprises an upper casing, a lower casing, a partition board and an exhaust muffling tube, and is characterized in that the muffler further comprises a water absorbing pipe, one end of the water absorbing pipe is communicated with the exhaust muffling tube, and a gap is arranged between the other end of the water absorbing pipe and the lower casing. By arranging one or a plurality of small-diameter absorbing pipes on the exhaust muffling tube inside the muffler, while the bottom end of the water absorbing pipe is about 5mm away from the lower casing of the muffler, the condensed water stored in the lower casing of the muffler can be absorbed through negative pressure generated by exhausting air flow, and then be discharged along with the exhausting air flow, thereby effectively preventing corrosion to the muffler materials.
Description
Technical field
The utility model relates to the automotive silencing vent systems, refers to a kind of automotive muffler of getting rid of condensed water particularly.
Background technique
At present, known exhaust silencer inside is not provided with any drainage means, so the water vapour that the burning of motor car engine internal cause produces is after the condensation knot is met at the suppressor case place, water of condensation can accumulate for a long time in silencing apparatus inside, and its pH value can reach 2.These residual acid condensate water can produce corrosion to the noise elimination modulator material, and then cause the silencing apparatus shortening even the ultimate failure in working life.
The model utility content
The purpose of this utility model is exactly in order to overcome above-mentioned existing silencing apparatus because of condensed water corrodes the problem that the silencing apparatus material influences its working life, a kind of automotive muffler of getting rid of condensed water to be provided.
To achieve these goals, a kind of automotive muffler of getting rid of condensed water of providing of the utility model comprises upper shell, lower shell body, dividing plate and exhausting silencer pipe.Its specialization is: described silencing apparatus also comprises at least one suction sleeve, and an end of described suction sleeve is communicated with described exhausting silencer pipe, is provided with the gap between the other end of described suction sleeve and the lower shell body.
The other end of described suction sleeve and the gap between the lower shell body are at 4～6mm.
Described suction sleeve and described exhausting silencer pipe can be to be welded to connect.
Described suction sleeve can be one.
Described suction sleeve can be two.
The diameter of described suction sleeve is preferably 8～10mm.
The beneficial effects of the utility model are: by one or more minor diameter suction sleeve is set on the exhausting silencer pipe of silencing apparatus inside, and the suction sleeve bottom apart from silencing apparatus lower shell body 5mm about, can be by the negative pressure of exhaust airstream generation, draw the condensed water that the silencing apparatus lower shell body retains, discharge with exhaust airstream again, prevented corrosion effectively the noise elimination modulator material.
Description of drawings
Fig. 1 is the utility model and embodiment's a structural representation;
Fig. 2 is the local structure for amplifying schematic representation of Fig. 1;
Among the figure, 1-upper shell, 2-lower shell body, 3-exhausting silencer pipe, 4-suction sleeve, 5-dividing plate.
Embodiment
Below in conjunction with the drawings and specific embodiments the automotive muffler of getting rid of condensed water of the present utility model is described in further detail:
As depicted in figs. 1 and 2, the automotive muffler of the condensed water got rid of in the present embodiment comprises upper shell 1, lower shell body 2, dividing plate 5 and exhausting silencer pipe 3, on exhausting silencer pipe 3, be welded with a diameter and be about the suction sleeve 4 of 8mm, one end of suction sleeve 4 is communicated with exhausting silencer pipe 3, the about 5mm in gap between the other end and the lower shell body 2.
When engine operation, exhaust airstream flows in exhausting silencer pipe 3, exhausting silencer pipe 3 inside and outsides produce pressure difference (negative pressure), and the condensed water of lower shell body 2 bottoms is sucked in the exhausting silencer pipe 3 by suction sleeve 4, and condensed water is met the water vapour of thermosetting and discharged the silencing apparatus outside with exhaust airstream.
Claims (6)
