The invention provides an automobile exhaust device, and belongs to the technical field of an automobile accessory. The automobile exhaust device solves the problem of poor
tail gas purification effect of the existing environment-friendly automobile
tail gas tube. The automobile exhaust device comprises an air inlet
pipe and an
exhaust pipe, wherein an air inlet end and an air outlet end are arranged on the air inlet
pipe, the inner side wall of the air inlet
pipe is in a conical shape, in addition, the
diameter of the inner side wall of the air inlet pipe is gradually reduced in the
airflow direction, a first annular groove is formed in the end surface of the air outlet end, the inner end of the
exhaust pipe is inserted into the first annular groove, a sealing
assembly used for connecting and sealing the inner end of the
exhaust pipe and the first annular groove is arranged between the inner end of the exhaust pipe and the first annular groove, a connecting structure used for fixedly connecting the air inlet pipe and the exhaust pipe is arranged between the air inlet pipe and the exhaust pipe, a clamp groove is formed in the exhaust pipe, wet curtain units are clamped and connected into the clamp groove, a sealing plate is also fixedly connected onto the outer edge of the outer end of the exhaust pipe, in addition, the position of the sealing plate is right aligned with the position of the wet curtain unit, a plurality of exhaust holes are formed in the sealing plate, and catalysts are filled between the sealing plate and the wet curtain unit. The automobile exhaust device has the
advantage of good
tail gas purification effect.
