Description

Technical Field

[0001] This utility model relates to the field of gas sampling technology, specifically a gas sampling device for environmental monitoring. Background Technology

[0002] Gas sampling is the process of collecting representative gas samples from specific environments such as the atmosphere, industrial plants, indoor spaces, and pipelines. As a crucial preliminary step in gas detection and analysis, its core function is to provide accurate and reliable data for environmental quality monitoring and control, industrial production process management and safety early warning, occupational health hazard assessment, scientific research data acquisition, and pollution source location and investigation through subsequent detection of sample components, concentrations, and other indicators.

[0003] However, traditional gas sampling methods generally suffer from low integration, cumbersome operation, and difficulty in guaranteeing sampling accuracy. Their sampling pumps, sampling tubes, and sampling containers are mostly scattered components, requiring individual assembly during on-site sampling. This is not only inconvenient to carry but also prone to delays due to missing components or improper connections. Most traditional devices lack standardized sealing structures, making them susceptible to gas leaks and the intrusion of outside air during sampling, resulting in insufficient purity of the collected gas samples and an inability to accurately reflect the gas composition of the target environment. Furthermore, traditional sampling methods largely rely on manual control of sampling rate and time, lacking real-time parameter monitoring and adjustment components, making it difficult to accurately control key sampling conditions such as negative pressure and flow rate, leading to poor repeatability and accuracy of sampling results. After sampling, the disassembly and storage of scattered components is haphazard, and sample containers are prone to damage and leakage due to inadequate protection, further affecting subsequent sample testing and analysis.

[0004] Based on this, the present invention provides a gas sampling device for environmental monitoring to solve the aforementioned technical problems. Utility Model Content
