The application discloses a
water quality detection
reagent storage device which comprises a
reagent bag and a protective tank used for placing the
reagent bag, wherein an upper end of the protective tank is provided with a closing cover structure used for closing the opening; the closing cover structure comprises a cover body, a connecting hole, a transmission hose and a sealing
assembly; the sealing
assembly is provided with at least one first
pipe body, one end of the first
pipe body is connected with the transmission hose by inserting into the transmission hose, and the other end of the first
pipe body is provided with a pipe orifice which forms a sealing film and is used for closing a reagent transmission path. The device can guarantee that the reagent in the reagent bag is not polluted when the device is in standby state; after one
water quality detection is completed, the transmission path
pollution problem is effectively avoided by replacing a
single component, and the accuracy of the next detection data is guaranteed; meanwhile, the device has the advantages of simple structure, low replacement component cost, strong practicability and good economy.
