Restore the original state, so that the second pull rod 28 gradually drives the slide plate 27 to move downward, so that the slide plate 27 squeezes the disinfectant water in the liquid storage cylinder 26, so that the disinfectant water quickly flows into the first connecting pipe 33, and then flows into the infusion tube 34 and is sprayed into the air pipe 3 through the nozzle 35, thereby disinfecting the harmful gas in the air pipe 3, so as to achieve the purpose of pre-treating the harmful gas. During the disinfection process, the first block 301 blocks the disinfectant water, so that the disinfectant water flows in the air pipe 3, and the disinfectant water flows into the collecting cylinder 49 through the second connecting pipe 47, thereby achieving the effect of collecting the disinfectant water, which is convenient for secondary recycling. When the collecting cylinder 49 is full of disinfectant water, the staff turns the second valve 51 to open the liquid outlet pipe 50, so that the disinfectant water is discharged through the liquid outlet pipe 50.
