Embodiment one
Fig. 1 is the gas release and the structure diagram of collecting device that the present embodiment is provided.As shown in Figure 1, this implementation
Example provides a kind of gas release and collecting device, including：
Gas generating unit 10, gas generating unit 10 has seal casinghousing (not shown) and sealing cover (not shown), close
Capsule body coordinates with seal cap sealing, and seal casinghousing is formed with accommodating chamber 11, and accommodating chamber 11 is used to accommodate inside gadget 20 to be detected；
Gas provides device 30, and gas provides device 30 and can be connected with gas generating unit 10；
Heating unit 40, heating unit 40 can support gas generating unit 10；
Gas capture devices 50, gas capture devices 50 can be connected with gas generating unit 10；
Wherein, gas, which provides device 30, to provide inert gas to gas generating unit 10, and heating unit 40 can be right
The inside gadget to be detected 20 accommodated in accommodating chamber 11 is heated, and gas capture devices 50 being capable of 10 row of captured gas generating means
The gas to be detected gone out.
Specifically, when the security and the feature of environmental protection that need to interior are detected, gas can be first turned on
Inside gadget 20 to be detected is put into accommodating chamber 11 by the sealing cover of device 10, then seals sealing cover and seal casinghousing, and will
The inert gas that gas is provided in device 30, is then passed through in gas generating unit 10, beats by the air extraction in annular seal space 11
It opens heating unit 40, the inside gadget to be detected 20 in gas generating unit 10 is heated, and maintain constant temperature, then it is to be checked
It surveys inside gadget 20 to be heated and release gas, the gas to be detected which mixes with inert gas is finally by gas trapping
Device 50 is trapped, you can is treated detection gas and is carried out ingredient and content detection, to determine the security of inside gadget 20 to be detected
Whether meet relevant criterion requirement with the feature of environmental protection.
After a certain inside gadget has been detected, the detection of other inside gadgets is if desired carried out, gas can be first turned on
Original inside gadget 20 to be detected in accommodating chamber 11 is taken out, and gas therein is thoroughly discharged by the sealing cover of device 10, than
It such as can be used and be passed through inert gas or vacuumize mode, then proceed by the detection of other inside gadgets, specific detection side
Method as above, does not repeat.It can be seen that the gas that the present embodiment is provided discharges and collecting device, 10 energy of gas generating unit
Enough be used repeatedly, solve need repeatedly to replace sampler bag in conventional bag method and caused by cost problem and environmental pollution
Problem.
The gas release and collecting device that the present embodiment is provided, can be to a variety of traffic such as automobile, car, track train
Inside gadget in instrument is detected, for example can be carpet, roof panels, driver seat assembly, front door interior trim assembly, secondary instrument
