The invention discloses an automobile
exhaust pipe having a waterproof function. The automobile
exhaust pipe comprises an
exhaust pipe body, an inner cavity and an exhaust
pipe outlet communicating with the inner cavity are disposed in the exhaust
pipe body, a separating plate is disposed in the inner cavity to separate the inner cavity into a first cavity and a second cavity, one end of the separating plate is connected with the wall of the inner cavity, the other end is connected with a
tail gas outlet in the first cavity, the wall, opposite to the
tail gas outlet, of the second cavity is a first slope, the face, facing to the first slope, of the separating plate is provided with a groove, one end of the exhaust
pipe outlet is large in open area, the other end is small in open area, the end, having the large open area, of the exhaust pipe is provided with a second slope, the second slope is arranged over the groove, and the inner wall, close to the second slope, of the second cavity is provided with a non return valve. By adopting the automobile exhaust pipe having the waterproof function,
tail gas passes through the tail gas outlet, the direction of the tail gas is changed by the first slope, and then the tail gas passes through the groove and is exhausted from the exhaust pipe outlet, water enters into the second cavity from the exhaust pipe outlet, water in the tail
gas passing through the groove can be drained from the non return valve, so the water will not enters into an automobile, an automobile engine can be protected.
