Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere detection, in particular to a sealed collection device for atmosphere detection. Background Art

[0002] Sealed sampling devices for atmospheric testing are devices specially designed to collect gas samples from the atmosphere and ensure that the samples remain well sealed during and after the collection process. This device is essential to ensure the representativeness of the sample, prevent cross contamination, and maintain the stability of the sample's chemical composition. It is particularly suitable for applications that require accurate measurement of trace pollutants or volatile organic compounds (VOCs), toxic and harmful gases in the atmosphere.

[0003] The vacuum air bag sampler is a sealed gas collection device used for atmospheric testing. This sampler uses vacuum box technology to exhaust the air inside the air bag by vacuuming, forming a negative pressure state, and then opens the valve connected to the outside atmosphere. The gas in the atmosphere will automatically fill into the air bag under the action of the pressure difference, thereby completing the collection of atmospheric samples in the target area. Since the air bag can be completely sealed, the collected gas samples can be kept in the state at the time of collection, which is convenient for subsequent precise analysis in the laboratory, and is especially suitable for the sampling of volatile organic compounds (VOCs) and other trace gas components. These samplers are usually designed to be lightweight and suitable for use in a variety of environments, including environmental monitoring, health and epidemic prevention, production safety inspections, and scientific research.

[0004] In order to be flexible in disassembly and assembly and convenient to carry, the vacuum air bag sampler in the prior art usually adopts a split design, in which the vacuum box and the vacuum pump are designed as separate components. There is no connecting mechanism and the vacuum box and the vacuum pump cannot be connected as a whole. Even if the volumes of the various parts of the split design are small, the two parts still need to be carried or placed when carrying and using, which is not conducive to quickly carrying out work in a small space or complex environment such as the wild.
