[0002] 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 constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Since the formulation of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, it is necessary to conduct water quality testing on water resources. During the water quality testing process, impurities in the water will affect the sampling, so it is necessary to filter the impurities in the water through a filter structure.

[0003] In the prior art, when testing water quality, water is usually collected and stored through a water collection cylinder with a filter frame inside, and then transferred to a water quality testing device for testing. However, the debris left by filtering in the filter frame is not easy to clean, and the filter frame needs to be removed from the water collection cylinder for cleaning, which is more troublesome. In addition, when the filter frame is removed, it is easy to contaminate the water to be tested, affecting the test quality. Utility Model Content
