when disinfection is carried out, disinfection liquid medicine is added into the annular medicine storage barrel 75 through the medicine adding pipe 712 by opening the box door 11, two liquids separated and filtered by the membrane separation device 4 are poured into the shell 6, the liquid level is lower than the medicine adding pipe 712, then the ultraviolet lamp 9 is started and the driving block 710 is pushed until the liquids cannot be pushed any more, the driving block 710 drives the sealing block 78 to move away, the medicine spraying pipe 76 is communicated with the annular medicine storage barrel 75, and the box door 11 is closed and the motor 8 is started;
the motor 8 drives the driving pipe 71 to rotate, the driving pipe 71 drives the nut 73 to rotate through the driving block 74, so that the nut moves downwards relative to the screw rod 72, and simultaneously the driving block 74 drives the annular medicine storage barrel 75 to rotate highly and move downwards, and due to centrifugal force, disinfectant inside the annular medicine storage barrel 75 is sprayed out through the spray holes 77 on the medicine storage barrel 76;
the annular medicine storage barrel 75 can move up and down and rotate at a high speed while spraying medicine, namely, water is stirred, so that medicine liquid can be more uniformly and fully contacted and mixed with the water, and the whole disinfection effect is better by matching with the ultraviolet lamp 9;
when annular medicine storage barrel 75 moves down to 6 bottoms of casing and triggers photoelectric switch, make the motor 8 reversal this moment, annular medicine storage barrel rebound this moment, move to the upside when annular medicine storage barrel 75 touches pressure photoelectric switch and makes, motor 8 reverse rotation once more.
