The inorganic solution flows into the inorganic waste liquid bin 23 along the inorganic waste liquid port 22 for storage. At this time, the shower head 26 arranged at one end away from the drain groove 20 is started, and pure water is pumped into the shower head 26 from the liquid storage bin 27 to clean the experimental container. When the experimental solution is an organic solution, after the experiment is completed, the organic solution is poured into the organic waste liquid port 24, and the organic solution flows into the organic waste liquid bin 25 along the organic waste liquid port 24 for storage. Finally, the ultraviolet lamp ring 17 arranged between the ventilation main body 1 and the first ventilation pipe 5 is started to sterilize the inside of the ventilation main body 1, and the atomizer 8 arranged at the output end of the disinfection bin 7 is started to atomize the disinfectant and spray it into the ventilation main body 1 to disinfect the ventilation main body 1.
