Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment of: a novel three-way catalytic converter comprises a shell 2, wherein a protective structure 6 is arranged outside the shell 2, the protective structure 6 comprises a connecting sleeve ring 602 wrapped outside the shell 2, the connecting sleeve ring 602 is sleeved outside the shell 2, fixing bolts 603 are arranged at the top end inside the connecting sleeve ring 602, a protective shell 601 is arranged at the bottom end of the connecting sleeve ring 602, a carrier catalyst 3 is arranged inside the shell 2, an inlet 1 is arranged at one side of the shell 2, a filtering structure 5 is arranged inside the inlet 1, and an outlet 4 is arranged at the other side of the shell 2;

the cross section of the protective shell 601 is larger than that of the shell 2, a clamping structure is formed between the protective shell 601 and the shell 2, the protective shell 601 and the shell 2 are matched with each other due to the design of the clamping structure, and the protective effect is better;
