s3: when the spray pipe (4) sprays the deodorant liquid downwards, the movable plate (7) is hit, so that a downward acting force is generated on the movable plate (7), the movable plate (7) moves downwards, the movable plate (7) drives the filter box (6) to move downwards through the connecting rope (602), the heater (8) is opened through the first control assembly, a microbial material (601) filled in the filter box (6) is heated, and the activity of microbes is improved;
s4: when the heater (8) heats the water tank (1) to a certain temperature, the second control component controls the fan (19) to be turned on, so that the treated gas is quickly discharged out of the water tank (1).
