[0002] A flow analyzer is an instrument used to detect water samples. It filters water samples through a filter membrane to obtain particles and impurities in the sample. However, during the use of the existing flow analyzer's filtration structure, the filter membrane needs to be cleaned or replaced after each filtration to maintain the stability of the filtration performance. However, when detecting water samples, there are particles and impurities of varying sizes in the sample, which requires frequent replacement of the filter membrane. The existing filter membrane replacement is cumbersome, resulting in a low filtration effect and a reduced service life of the filter membrane. In view of this, we propose a filtration structure for a flow analyzer for water sample detection. Utility Model Content
