[0025] Working principle:

[0026] Initial work phase

[0027] Inside the gynecological department where the micro-oxygen private protection instrument is measured, the power panel 2 supplies power to the internal measuring gas chamber 301, the first solenoid valve 6, the second solenoid valve 11 and the electric telescopic rod 7 through the operating control panel 13, and the measured gas enters the first L-shaped pipe joint 404 from the air inlet nozzle 403. The filter net 405 inside the first L-shaped pipe joint 404 isolates the insects and lumps of dust in the gas to ensure the cleanliness of the interior.

[0028] Measurement phase

[0029] The measured gas enters the measuring gas chamber 301 from the first pipeline 5, the first solenoid valve 6, the regulating member 303 and the input pipe 302 and is measured by the internal sensor. When it is detected that the oxygen concentration in the measured gas exceeds the standard, the electric telescopic rod 7 is extended and retracted upward to drive the sealing cap 305 at the end of the connecting rod 306 to move upward, so that the sealing cap 305 is separated from the air release head 304, and the measured gas is discharged from the air release head 304, which can reduce the measured gas from entering the measuring gas chamber 301.
