【 Working principle 】 :
When inhaling, a and D. b and C. Inhaling outside air in cavity D. Inhaling high concentration CO2 gas in cavity c; When exhaling, a and c pass, d and e pass, d and e pass, and the gas in cavity d is sent to the analyzer to detect the CO2 concentration. The high concentration of CO2 in cavity c is discharged out of the mouth.
