Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a VOC waste gas detection instrument. Background Art

[0002] VOC is the abbreviation of volatile organic compounds. In the common sense, VOC refers to volatile organic compounds; however, in the environmental sense, it refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm. Therefore, the demand for a VOC exhaust gas detector is growing.

[0003] There are still problems when using the detector:

[0004] When existing detectors detect gas, they usually do so by inserting the connecting tube on the detection head into the exhaust pipe and ionizing the gas through the detection head. However, since the gas inside the exhaust pipe is circulating, it will affect the detection result. Moreover, when performing the detection, if the opening of the connecting part of the exhaust pipe is too large, some exhaust gas will be discharged from the exhaust pipe. In view of the above problems, the inventors have proposed a VOC exhaust gas detection instrument to solve the above problems. Utility Model Content
