Description

Technical Field

[0001] The utility model relates to the technical field of environmental management devices, in particular to a sampling device for indoor environmental pollution management. Background Art

[0002] Indoor environmental pollution has always been one of the important issues that people are concerned about. With the development of modern society and the acceleration of industrialization, there are more and more harmful substances in indoor air, such as formaldehyde, benzene, TVOC total volatile organic compounds, etc. These harmful substances pose a potential threat to human health and may cause respiratory diseases, skin allergies and other problems. Therefore, it is particularly important to effectively control indoor environmental pollution.

[0003] In order to effectively control indoor environmental pollution, it is necessary to first accurately detect and evaluate the pollution situation. Traditional indoor pollution detection often relies on sampling devices to assess indoor air quality by collecting air samples and analyzing the harmful substances in the samples. However, traditional sampling devices have some defects, such as the fixed position of the sampling head, the inability to flexibly change the sampling position, and the limited number of sampling ports. The sampling device needs to be constantly rotated to collect air samples in different directions, which is cumbersome to operate. Utility Model Content
