[0002] Water environment testing, analysis and sampling is a rigorous scientific activity aimed at evaluating water quality and ensuring the safety and suitability of water resources. When conducting water environment testing, analysis and sampling, a water sampling device is usually required. A water sampling device, that is, a water quality sampler, is an important tool for collecting water quality samples. With the rapid development of industrialization and urbanization, water pollution problems are becoming increasingly serious. Timely and accurate monitoring of water quality has become an important means to ensure water resource safety and maintain ecological balance. Water quality monitoring not only involves drinking water safety, but also industrial water use, agricultural irrigation, ecological environment and other fields. Therefore, the requirements for water quality monitoring technology are also getting higher and higher.

[0003] In the traditional water environment testing and analysis process, the sampling method often faces many limitations. In the traditional sampling process, water samples need to be taken from multiple different locations. During continuous sampling, the last sample often remains in the pipeline, resulting in inaccurate samples for the next sampling. The traditional sampling process lacks an effective filtration pretreatment mechanism, which can easily cause impurities mixed in the water sample to interfere with subsequent testing and analysis, reducing the accuracy of the results. In addition, some sampling devices usually lack flexible height adjustment functions, making it difficult for operators of different heights to achieve optimal comfort when using them.
