[0002] As people become more aware of and pay more attention to health, the quality of the environment is becoming more and more important. Among them, air quality is one of the important indicators of environmental quality. In order to be able to detect air in a wider range, air collection devices are usually used to collect and concentrate the air for detection. This not only saves time and effort, but also has higher detection accuracy. However, due to the influence of temperature, the chemical composition or density of indoor gases may be different at different heights indoors. Since there is generally a height difference of about 2 meters from the floor to the roof indoors, it is necessary to collect air at different positions and heights in the room for joint detection and evaluation. However, existing collection equipment generally cannot collect indoor air at different heights well, and collection is very troublesome, which is not conducive to improving the detection efficiency and detection accuracy of indoor air. For this reason, we propose a gas collection device for indoor chemical gas detection. Utility Model Content
