Abstract

The invention includes a fixing sleeve and a seat set. The fixing sleeve has a connecting portion with an inner thread and is fastened onto an exhaust pipe. The seat set has a connecting end with an outer thread and a sleeve end with an inner thread. The connecting end is screwed to the connecting portion. An inner side of the seat set is coated with a catalytic conversion agent.

Claims

1. An oxygen sensor seat structure, comprising:

a fixing sleeve, having a connecting portion with an inner thread, and fastened onto an exhaust pipe; and

a seat set, having a connecting end with an outer thread and a sleeve end with an inner thread, wherein the connecting end is screwed to the connecting portion, an inner side of the seat set is coated with catalytic conversion agent.

2. The oxygen sensor seat structure of claim 1, wherein the fixing sleeve is formed with a flange.

3. The oxygen sensor seat structure of claim 1, wherein the seat set includes a first seat and a second seat, the first seat is an arc-shaped tube, one end of the first seat is a first connecting end with an outer thread, another end thereof is a first sleeve end with an inner thread, the first seat is fastened to the fixing sleeve by screwing the first connecting end to the connecting portion, the second seat is a straight tube, one end of the second seat is a second connecting end with an outer thread, another end thereof is a second sleeve end with an inner thread, and the second seat is fastened to the first seat by screwing the second connecting end to the first sleeve end.

4. The oxygen sensor seat structure of claim 3, wherein the first connecting end of the first seat is screwed with a nut.
