Exhaust pipe for automobile

Abstract

The invention relates to the technical field of automobile accessories and discloses a smoke discharging pipe for an automobile. A smoke pipe and a protective plate are included; the smoke pipe is provided with a smoke inlet and a smoke outlet; the smoke pipe is provided with a gas inflow one-way valve; a dustproof structure is arranged in the smoke pipe; the dustproof structure comprises a filterscreen and a rotating fan which comprises spiral blades and an outer frame; a convex block is fixed to the outer frame; the smoke pipe is provided with a waste material port; the protective plate isfixedly connected with the smoke pipe; an annular cavity, a high-pressure gas cavity and a part portion are formed between the smoke pipe and the protective plate due to partition plates and a supporting plate; the annular cavity is provided with a gas outlet; the high-pressure gas cavity communicates with the annular cavity through a first gas outflow one-way valve; the upper portion of the partportion is provided with a gas bag; the gas bag communicates with the high-pressure gas cavity through a second gas outflow one-way valve; the gas bag is provided with a spring abutting against the filter screen; and the smoke pipe is provided with a heat insulating plate used for insulating heat of the annular cavity. The smoke discharging pipe for the automobile can prevent that the smoke discharging pipe for the automobile is blocked, and particle impurities in the smoke discharging pipe can be conveniently treated.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a smoke exhaust pipe for automobiles. Background technique [0002] Automobiles are power-driven, non-track-bearing vehicles with 4 or more wheels, mainly used to: carry people and (or) goods; tow vehicles that carry people and (or) goods. [0003] Although science and technology are now developing towards electric vehicles. However, under the prior art environmental conditions, most automobiles are driven by a gasoline engine, and the combustion efficiency of the gasoline engine cannot reach 100%, and the incomplete combustion of gasoline in the gasoline engine will produce carbon dioxide, carbon monoxide and other impurities. Both carbon monoxide and carbon dioxide emissions will affect the ambient air, and impurities will cause the PM value of the air to rise above the safe value, and air exceeding the safe value can easily cause respiratory diseases in the human body.
