Embodiment 1

[0044] Such as figure 1 As shown, the automobile exhaust device is composed of an intake pipe 1, an exhaust pipe 2, a wet curtain unit 3, a sealing plate 4 and the like. Wherein, the intake pipe 1 is cylindrical and the two ends of the intake pipe 1 are the intake end 1a and the outlet end 1b respectively, and automobile exhaust enters the intake pipe 1 through the intake end 1a and is discharged from the outlet end 1b.

[0045] The exhaust pipe 2 includes a connecting pipe 2a and an air outlet pipe 2b connected to each other. Both the connecting pipe 2a and the air outlet pipe 2b are cylindrical and the center lines of the two are collinear. Specifically, the outer edge of the connecting pipe 2a has a protruding annular connecting portion 2a1, and the outer edge of the air outlet pipe 2b is correspondingly provided with an annular connecting portion 2b1, and the annular connecting portion 2a1 and the annular connecting portion 2b1 are passed through several screws 5 The conn...

Embodiment 2

[0061] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that the sealing assembly 8 includes an O-shaped sealing ring 8a located in the second annular groove, and the inner peripheral surface of the O-shaped sealing ring 8a is in contact with the annular groove. The inner walls of the groove two are offset.

Embodiment 3

[0063]The structure and principle of the third embodiment are basically the same as that of the first embodiment, except that the sealing assembly 8 includes a ring-shaped first sealing gasket 8b located on the inner bottom wall of the annular groove, connected to the end surface of the inner end 2a2 of the pipe Offset against the upper first gasket 8b.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automobile accessories and relates to an automobile exhaust device. Background technique [0002] At present, the number of cars per capita in my country is rising rapidly. Cars emit a large amount of unfiltered exhaust every day. The pollution of automobile exhaust is becoming more and more serious. The large amount of automobile exhaust makes the urban air quality continue to decline, and the air pollution is worrying. [0003] Aiming at the problems existing in the prior art, people have realized that they don’t know and make improvements, such as an environmentally friendly automobile exhaust cylinder [application number: 201210447955.2; publication number: CN102900493A] disclosed in China Patent Library, which includes exhaust port automobile exhaust cylinder, partition Heat ring, exhaust gas inlet, locking device and activated carbon layer, one end of the automobile exhaust cylinder is connected to ...
