Automobile exhaust pipe having waterproof function

Abstract

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.

Description

technical field [0001] The invention relates to an automobile exhaust pipe, in particular to an automobile exhaust pipe with waterproof function. Background technique [0002] The waterproof technology of automobile exhaust pipes has always been one of the problems in the world's automobile industry. The exhaust devices of existing automobiles are mostly mufflers lying under the longitudinal beams of the frame, or arranged outside the frame. Some of the mufflers are arranged vertically. The exhaust port faces the rear, but these arrangements have always had the problem that the exhaust port is easy to enter water, especially when the car passes through the water-logged road, the water floods the exhaust pipe of the car, causing the engine to enter water, and the car stalls in the water. In this case, general occlusion measures are not practical. [0003] At present, according to the current understanding of social vehicles, domestic and foreign automobiles basically adopt t...
