AI Technical Summary
The air inlet of existing exhaust gas detectors is easily blocked by dust, which affects the normal operation of the detection work.
A portable automatic exhaust gas detection device was designed, which uses a servo motor-driven cleaning component and a fan. The exhaust gas is drawn into the detection box through the air inlet pipe for detection, and after the detection is completed, the servo motor drives the cleaning component to rotate and clean the dust on the protective screen.
Automated dust cleaning is achieved, preventing air inlet blockage and ensuring the continuity and accuracy of testing.
