s6, after the experiment, the spraying disc (35) continuously sprays the atomized sterilization reagent to the experiment bin (26) for disinfection and sterilization, at the moment, the electromagnetic valve (41) on the second air outlet pipe (39) is closed, the electromagnetic valve (41) on the first air outlet pipe (42) is opened, the air suction pump (37) continuously discharges the atomized sterilization reagent into the experiment bin (26) through the air suction pipe (38) and the first air outlet pipe (42), the atomized sterilization reagent is recycled, and the waste of the sterilization reagent is reduced.
