Air purification sterilizer

The air purification and disinfection machine comprises a machine base, a purification box and a function box are installed at the top of the machine base, and a filter box is installed at an opening in one side of the purification box. When the coarse filter screen, the HEPA filter screen and the activated carbon screen plate are seriously blocked, a water pump is started to pump out clean water in the functional box, the functional box can be communicated with the corresponding Z-shaped shell through an electromagnetic valve, then the clean water flows into the spraying pipe through the Z-shaped shell to be sprayed and cleaned, stains with high adsorbability are prone to being left on the coarse filter screen and the HEPA filter screen, and the cleaning effect is good. Therefore, a turbine is further installed in the Z-shaped shell corresponding to the position, the turbine is driven by water flow to rotate during cleaning and then drives a vertical shaft to rotate, a first bevel gear drives a second bevel
