Abstract
The utility model discloses an inflow-prevention device of an automobile exhaust pipe. The device comprises a bend pipe. The upper end of the bend pipe is connected with a pipe opening of the exhaust pipe in sealing mode, and a plurality of slim pipes used for exhausting gas are arranged abreast in the bend pipe and are fixed in the bend pipe through a plurality of location plates. A water blocking valve is installed at the lower end of the bend pipe, and the lower end of the bend pipe and the water blocking valve are inclined relative to the horizontal level. The water blocking valve comprises a cover body bestrewn with mesh holes and a plurality of rubber balls identical with the slim pipes in number, the rubber balls are arranged under pipe openings of the slim pipes correspondingly, a gap is retained between the pipe opening of each slim pipe and each rubber ball, and the diameter of the rubber ball is larger than that of the slim pipes and the mesh holes. Under normal condition, the rubber balls cannot block the pipe openings of the slim pipes due to the effect of air flow, and tail gas is exhausted outwards from the exhaust pipe, the slim pipes and the mesh holes of the cover body. When an automobile wades into water, the rubber balls can block the pipe openings of the slim pipes under the effect of water buoyancy and prevent the water from entering, and the tail gas can still be discharged from the position close to the pipe openings of the slim pipes.
