Extended joint structure

Abstract

Provided is an extended joint structure, which includes a sleeve body and a catalytic structure. The sleeve body is provided with an air inlet, an air outlet, and a catalytic chamber, one end of sleeve body is connected to an air exhaust pipe, and the other end of the sleeve body is connected to an oxygen sensor, so that the gas in the air exhaust pipe flows into the catalytic chamber through the air inlet and then flows out from the air outlet to the oxygen sensor; the catalytic structure is provided inside the catalytic chamber to catalyze the gas flowing through the catalytic chamber to improve the quality of the gas flowing out from the air outlet. This application has the effect of improving the detection environment of oxygen sensors by catalytic treatment of flowing gas, thereby enhancing the stability of detection signals.
