[0040] Working principle: When it is necessary to detect the gas sample, first open the cover 104, then take out the sampling tube 230, then press the piston rod 232 to discharge the gas inside the sampling tube 230, then align the abutting head 233 of the sampling tube 230 with the position where sampling is required, pull the piston rod 232 of the sampling tube 230 to allow air to enter the inside of the sampling tube 230, and then put the sampling tube 230 into the positioning groove 121 of the placement groove 120, so that the magnet ring 231 of the sampling tube 230 is magnetically attracted to the iron ring 231 of the positioning groove 121.

At this time, each air storage bag 224 becomes deflated and gas detection can be performed. Then the solenoid valve 223 is opened again to extend and push the electric push rod 112 The piston rod 232 allows the remaining air inside the sampling tube 230 to be sent into the air storage bag 224, then the solenoid valve 223 is closed and the micro air pump 212 is opened. The gas inside each air storage bag 224 passes through the air inlet head 202 and enters the sensor 201 for detection, and then the gas passes through the exhaust head 203 and enters the multi-lumen tube 210 and is discharged through the micro air pump 212. Simultaneous detection of multiple samples can be achieved, thereby facilitating the use of the air quality detection device when there are many samples, increasing the convenience of using the air quality detection device.
