[0002] Pure water refers to water that is pure, does not contain any impurities, and is composed of a single substance, H2O. It effectively prevents various pathogens from invading the human body. Its advantage is that it can effectively and safely replenish water to the human body. It has a strong solubility, so it has a strong affinity with human cells and has the effect of promoting metabolism.

[0003] In the related art, a pure water pH value detection device is designed, including a detection table, a detection disk is arranged on the surface of the detection table, a detection cup for carrying a sample to be detected is arranged on the surface of the detection disk, a lifting device is arranged above the detection table, a PH detector is arranged on the piston rod end wall of the lifting device, the PH detector is located above the detection cup, a control panel is arranged on the side wall of the detection table, the control panel is electrically connected to the PH detector, the PH detector is inserted into the detection cup through the lifting device, the pH value of the pure water sample in the detection cup is detected, and the detection result is sent to the control panel for recording.

[0004] With respect to the above-mentioned related technologies, the following problems exist: after the pH tester is inserted into the test cup and contacts the sample, part of the sample solution will adhere to the side wall of the pH tester. Since the buffering capacity of pure water is poor, pure water is easily contaminated. Water droplets of different test samples adhere to the side wall of the pH tester. When the next set of tests is carried out, the water droplets will follow the pH tester into the next test cup, affecting the sample in the test cup and causing inaccurate test results. Therefore, this needs to be improved. Utility Model Content
