[0003] China Patent Network discloses a gas detection device CN212622509U for environmental detection. The utility model mainly puts the balloon after collecting gas into the transparent cover, and pushes the pull plate through the handrail to make one end of the pull plate enter the bottom plate to form a closed space, and then pushes the ejector pin through the pull ring to puncture the balloon to avoid the leakage of collected gas and the mixing of external gas. This method is complicated and inconvenient to operate, and because the balloon is consumed each time, it will cause a lot of resource waste. Utility Model Content

If there is a large amount of gas in the airbag, you can open the air vent to discharge some of the original gas during inflation to increase the concentration of the gas to be tested in the gas detection chamber. After the detection is completed, remove the airbag, open the air vent, inject air into the gas detection chamber through the airbag installation port, and discharge the detection gas to avoid affecting the next detection.

[0007] Preferably, the detection machine includes a gas detection chamber, an airbag installation port, an air release port and an operation panel.

The airbag installation port and the air release port are both one-way valve structures and are connected to the internal space of the gas detection chamber. The operation panel is arranged on the front of the detection machine.

[0008] Preferably, the airbag includes an airbag deflation port, a locking device and an airbag air inlet port. The airbag is a foldable inflatable gas made of silicone. The airbag deflation port is arranged at the bottom of the airbag, and the airbag air inlet port is arranged at the top of the airbag. The airbag deflation port and the airbag air inlet port are both one-way valve structures, and the locking device is a mechanical latch structure arranged in a circle around the airbag deflation port.

[0009] Preferably, the airbag installation port is provided with a slot structure for connecting and fixing the airbag, which is locked with a locking device on the airbag.
