Automobile exhaust pipe with waterproof function and filtering function

Abstract

The invention discloses an automobile exhaust pipe with a waterproof function and a filtering function. An air inlet of a pipe body is in a conical shape with a diminishing caliber, an air outlet is formed in a conical shape with an incremental caliber, an inserting groove is formed in a connecting part arranged between the air inlet and the air outlet, a sealing ring is arranged in the insertinggroove, a downward waterproof blocking piece is arranged on the inner wall of the pipe body, and a movable waterproof blocking piece mechanism capable of moving towards the waterproof blocking piece is arranged between the waterproof blocking piece and the air outlet end of the pipe body when water enters the pipe body. A filtering device is arranged in a communicating pipe, and an ellipsoidal filtering layer is arranged in the filtering device. According to the automobile exhaust pipe, tail gas emission is facilitated, the heat dissipation effect can be well achieved, and the filtering effectis obvious; and gas can be circulated with each other, so that the air pressure is equal, the return pressure is balanced, and gas does not pollute each other. When the waterproof blocking piece andthe sealing ring are connected together, the pipe body can be effectively sealed, and the waterproof property is high.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust pipe equipment, and in particular relates to a waterproof and filtered automobile exhaust pipe. Background technique [0002] At the same time, with the rapid growth of urban motor vehicles, the phenomenon of environmental pollution caused by traffic noise is also becoming more and more prominent. The biggest hazard of automobiles to environmental protection is noise pollution and air pollution. According to the survey, motor vehicle noise accounts for 75.5% of urban noise. , with the development of automobile energy saving and emission reduction, automobiles are required to reduce noise and save energy consumption. The main noise of the car comes from the exhaust system of the car, that is, the noise of the exhaust emission of the automobile. In order to reduce the noise of the exhaust emission of the automobile, it meets the requirements of automobile environmental protection. The ex...

Problems solved by technology

Existing automobile exhaust pipes usually only have one exhaust main pipe, and in use, since the usual automobile exhaust pipes are arranged at the bottom of the automobile, the exhaust pipe at a lower position should The pipe is very easy to cause water to flow back into the exhaust pipe, which is easy to cause engine damage

At present, there is no effective device to solve the problem of automobile anti-backflow
