[0002] Water is the source of life. People cannot live without water in their lives and production activities. The quality of drinking water is closely related to people's health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are also constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly. Since the formulation of drinking water quality standards is related to people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, etc., there are differences in the requirements for drinking water quality not only between countries, but also between different regions in the same country. For the sake of people's health, we need to test the water quality regularly.

[0003] When testing water quality, a sampling device is needed to extract water. Currently, general sampling devices have a simple structure. If there are impurities such as aquatic plants and fallen leaves in the river, the sampling device will easily absorb the impurities when absorbing water, which makes it inconvenient for subsequent extraction and testing. Therefore, the sampling device in the existing technology generally adds a filter to the port at the water inlet to filter out impurities in the water. However, from a practical point of view, impurities are easily covered on the filter after being intercepted by the filter, which will seriously reduce the water flow rate of the filter and affect the water extraction efficiency.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content
