AI Technical Summary
Technical Problem
The existing exhaust gas detection sensors are bulky and costly, and are not suitable for ordinary users.
Method used
A reflective sensor is designed, using a light source assembly to emit light. The light is transmitted in the first optical path in the reflective rod, and is received by the light source assembly after contacting the external exhaust through the air guide hole to achieve limited detection.
Benefits of technology
It realizes exhaust gas detection with small structure, low cost and good measurement effect, and is suitable for ordinary users.

Abstract
The present invention discloses a reflective sensor, which includes a reflective rod, a light reflecting member installed at one end of the reflective rod, and a first optical path disposed in the reflective rod along a first direction and having one end correspondingly arranged with the light reflecting member. A vent hole is formed in the reflective rod along a second direction, passing through the first optical path and communicating with the outside. A light source assembly is installed at the other end of the reflective rod. In the present invention, light is emitted by the light source assembly, the light is transmitted in the first optical path, and after the light contacts the external exhaust gas through the vent hole, it is received by the light source assembly for finite detection. The structure of the present invention is small, low in cost, and good in measurement effect.
