▎ 摘　　要

NOVELTY - The device has a water storage tank arranged on a detecting machine (1) that is arranged with a screw thread shaft. A lower end of the water storage tank is arranged with a water pipe that is rotatably connected with a Q11F-16P type control valve. The detecting machine is formed with a groove (5). The screw thread shaft is closely welded with a spring that is rotatably connected with a spiral shaft. A clamping strip (4) is located in the groove. An upper end of a cover plate (6) is provided with two clamping grooves (7). The clamping strip is clamped into the clamping grooves such that the cover plate is tightly matched with the detecting machine. USE - Graphene water purity detecting device. ADVANTAGE - The device can detect water in a water storage tank so as to control rotation of a valve by a user. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene water purity detecting device. Detecting machine (1) Clamping strip (4) Groove (5) Cover plate (6) Clamping grooves (7)
