NOVELTY - The utility model belongs to the technical field of detector, especially a graphene water purifying agent detector water quality filtering mechanism, comprising a shell structure set of the detector shell, the detector shell of the outer side wall left end upper screw thread is connected with a first screw; When using the mechanism, firstly the user the first screw, the detector shell is sleeved on the water tap, then the first screw is screwed, the detector shell is fixedly mounted on the water tap, saves the step of soaking hot water, the graphene water purifying agent is set, realizing prolonging the filtering time of the mechanism; after using the mechanism for a period of time, the user finds that the PP cotton is completely discoloured, namely the rotary nut is screwed; the PP cotton is taken out; then the second screw is loosened; the baffle door is opened; it is convenient for the user to change the graphene water purifying agent; after the replacement is finished, the second screw is screwed tightly on the baffle door; The new PP cotton plug into the detector shell, screwing cap, realizing the operation of changing the mechanism filter core.
