Technical field
The present invention relates to a kind of automobile exhaust pipe, and in particular to a kind of automobile exhaust pipe with water-proof function.
Background technology
The waterproof technique of automobile exhaust pipe is always one of problem of world car industry, and the exhaust apparatus of existing automobile is more
It is lying in for silencer below longitudinal beam, or is arranged in frame outside, some arranges silencer vertically, exhaust outlet direction
Rear, but there is the problem of exhaust outlet is easily intake always in these arrangements, particularly when automobile is by ponding road surface, water submerged
Automobile exhaust pipe, causes water inflow of the engine, and automobile stops working in ponding, in this case, and the general measure of blocking is not
Practical.
At present for present public vehicles understanding, automobile both domestic and external on the waterproof technique of automobile exhaust pipe substantially
It is by the way of blast pipe internal punches, not there is too obvious effect.A kind of row is found when consulting Chinese patent net
Tracheae water-tight device, it be blast pipe uplink be connected to upwardly extend and outlet level bend pipe, bend pipe is connected with blast pipe
Mouth external diameter is circle, and the shapes and sizes of internal diameter are identical with the external diameter of the blast pipe mouth of pipe.Its outlet port is improved, is prevented into water；
Due to different automobiles, the caliber shapes and sizes of its blast pipe are different, to ensure that bend pipe is connected with the close of blast pipe, and spy will
Rubber tube is set at its seam, using the sealing of round tube, effectively prevents gas leakage from intaking.It is contemplated that aesthetic property and side
Just property, this scheme can not be in masses' popularization.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of vapour with water-proof function
Vehicle exhaust pipe, dividing plate is provided with blast pipe, after automobile exhaust pipe is by water submerged, by the air-flow of vehicle exhaust, will be arranged
Tracheae outlet is divided into tail gas discharge and water circulation two parts, and water is discharged from check valve, do not entered in automobile.
Technical scheme：In order to solve the above technical problems, a kind of automobile exhaust pipe with water-proof function of the present invention, including
It is vented in tube body, exhaust tube body and dividing plate, dividing plate is installed provided with inner chamber and the exhaust outlet connected with inner chamber, interior intracavitary
Inner chamber is divided into the first chamber and the second chamber, the wall connection of dividing plate one end and inner chamber, the other end goes out with the tail gas positioned at the first intracavitary
Mouthful connection, offgas outlet just to the second cavity wall be the first inclined-plane, the face on dividing plate towards the first inclined-plane is provided with groove, and blast pipe goes out
Mouth one end open area is big, and other end aperture area is small, and the big one end of exhaust outlet area is provided with the second inclined-plane, the second inclined-plane
Above groove, the second chamber is provided with check valve on the inwall on the second inclined-plane, and tail gas is oblique by first from offgas outlet
Face changes after direction, is then discharged by groove from exhaust outlet, and water enters the second intracavitary from exhaust outlet, by recessed
The tail gas of groove discharges water from check valve.
Preferably, the groove is that plane, two sides are that inclined-plane is constituted by bottom surface, tail gas enters in groove, by recessed
Inclined-plane in groove changes the direction of motion of tail gas.
Preferably, the inclined-plane of the groove and bottom surface angle are 120 °~135 °.
Preferably, first inclined-plane and offgas outlet axis angle are 45 °.
Beneficial effect：The automobile exhaust pipe with water-proof function of the present invention, is provided with dividing plate in blast pipe, as automobile row
Exhaust outlet, by the air-flow of vehicle exhaust, is divided into tail gas discharge and water circulation two parts, water by tracheae by after water submerged
From check valve discharge, do not enter in automobile；And over-pressure gas can also be entered by check valve in engine non-normal working
Row pressure release, with anti-tamper blast pipe.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of automobile exhaust pipe with water-proof function of the present invention, including exhaust tube body 4, blast pipe
Provided with inner chamber and the exhaust outlet 3 connected with inner chamber in body 4, interior intracavitary is provided with dividing plate 8, and inner chamber is divided into the by dividing plate 8
The wall connection of one chamber and the second chamber 7, the one end of dividing plate 8 and inner chamber, the other end is connected with the offgas outlet 6 positioned at the first intracavitary, tail
Gas outlet 6 just to the wall of the second chamber 7 be the first inclined-plane 5, dividing plate 8 towards the first inclined-plane 5 face be provided with groove, exhaust outlet 3
One end open area is big, and other end aperture area is small, and the big one end of the area of exhaust outlet 3 is provided with the second inclined-plane 2, the second inclined-plane
2 are located above groove, and the second chamber 7 is provided with check valve 1 on the inwall on the second inclined-plane 2, and tail gas passes through the from offgas outlet 6
One inclined-plane 5 changes after direction, is then discharged by groove from exhaust outlet 3, and water enters the second chamber 7 from exhaust outlet 3
It is interior, water is discharged from check valve 1 by the tail gas of groove.
In the present invention, the groove is that plane, two sides are that inclined-plane is constituted by bottom surface, and tail gas enters in groove, passes through
