[0044] Implementation process: First, open the plug 15, pour the water to be detected into the filter head body 11. The water to be detected filters impurities through the filter screen 12 and the filter membrane 13. During filtration, since the filtration speed of the filter membrane 13 is slow, a suction filtration device needs to be used. After using the suction filtration device, the vacuum degree in the mixing chamber 5, the sampling tube 4, and the collection box 8 increases.

The guide vanes 14 in the mixing chamber 5 are arranged in a spiral shape downward, and there are gaps between each guide vane 14, which can increase the mixing effect without affecting the change of air pressure. Finally, the processed sample mixed with the reagent flows into the detection tube 10, and then the detection tube 10 is inserted into the sample installation port 2 for detection.
