In other embodiments, the drain port 38 may be in communication with a waste collection device via a conduit.

In summary, the working process of the disinfection machine in this embodiment is as follows:

the fan 2 works to generate negative pressure, and the external air is sucked into the air duct inside the sterilizer from the air inlet of the shutter at the bottom of the sterilizer. The high-voltage electrostatic module kills germs in the air and primarily adsorbs suspended particles such as dust in the air. Then the air is disinfected by ozone through the ozone reduction layer and the peculiar smell is eliminated. And then the air is heated by the high-temperature auxiliary heating layer to kill germs and catalytically decompose residual ozone on the upper layer into oxygen, so that the damage to a human body caused by excessive ozone emission is avoided. And finally, the high-efficiency filter layer uses a high-efficiency filter element to finally filter the air and then the air is discharged out of the sterilizing machine through a centrifugal air duct. After the disinfection function of the disinfection machine is used for a period of time, a user presses the self-cleaning function, the fan 2 works and rotates firstly, the heating device 37 starts preheating, the opening and closing valve 34 is opened, the cleaning water is pumped out from the cleaning tank 31 by the power pump 35, the water is heated at high temperature by the heating device 37 to form steam, the steam is sprayed to the blades of the impeller 21 through the spray head 32 for cleaning, and the steam is thrown to the inner wall of the air channel due to the inertia effect after being liquefied into water to form the effect of washing and cleaning the air channel. The water for washing the air duct flows to the liquid accumulating disc 36 along the inner wall and finally flows to the waste water collecting device through the water outlet 38, and the cleaning process of the air duct and the fan is completed.
