The upper gear 131 drives the water inlet gear 109 and the water inlet valve core 127 to rotate ninety degrees through the external transmission belt 128, and drives the return valve core 125 to rotate ninety degrees through the sliding folding tube 126, so that the return water ball valve 124 opens and the water inlet ball valve 108 closes. The top gear 130 drives the transmission gear 206 to rotate through the long transmission belt 204, and at the same time, the long transmission belt 204 drives the lifting piece 205 to move. At the same time, the pipeline pump 207 is started, and the water source enters the lower water inlet pipe 137 through the water inlet tee 107, then enters the return pipe 123, and enters the disinfection box 301. The transmission gear 206 drives the rack push plate 306 to slide inward through the docking gear 305, and the blocking frame 307 is lifted up by the rack push plate 306. The blocking frame 307 no longer blocks the disinfection powder box 308, and the pop-up spring 309 rebounds, and the disinfection powder box 308 pops up. The water source is mixed with the disinfection powder, and the water source is mixed with the disinfection powder. Then the disinfectant water enters the recoil ball valve 210 and the riser 113 through the upper recoil pipe 208, enters the RO membrane 104 through the connecting tee 111 and the connecting pipe 112, and then enters the filter element 103, and then enters the water inlet pipe 106 and the recoil tee 110, and returns to the return pipe 123 through the return ball valve 124 to form a cycle, thereby realizing the disinfection and sterilization flushing of the pipeline.When the flushing is completed, the connecting pipe 112 rotates again to reset, and the rack push plate 306 continues to move forward. At this time, the rack push plate 306 will not lift the next blocking frame 307. At this time, the lifting piece 205 lifts the lifting block 304 and the closing plate 303. The connecting pipe 112 rotates twice to lift the lifting block 304 once, and the remaining sewage in the disinfection box 301 and the pipeline is discharged from the discharge pipe 302. When the connecting pipe 112 rotates next time, the rack push plate 306 lifts the next blocking frame 307, and repeats this process.
