NOVELTY - The utility model claims a light medium catalytic composite function air sterilizer, the air sterilizer comprises a device main body, a PM2.5 static filter plate, a mute axial flow fan, a special ultraviolet generating lamp, a ceramic composite graphene titanium plate and a negative oxygen ion generating device, the shell is provided with an air inlet, air outlet and operation display panel. the air outside the device firstly passes through the PM2.5 static filter plate set by the air inlet, the air is pre-processed, the remove is relatively large particulate matter the air; secondly, sterilizing and purifying the air through the optical medium catalytic area; finally, further processing by the negative oxygen ion generating device and then uniformly discharging. and the air sterilizer is provided with an automatic detecting system and a manual, automatic switching system, after starting, firstly performing fault detection, when there is no fault, automatically entering the working state; when there is fault, stopping working. The utility model can quickly sterilize the air, sterilize and purify, improve the quality of the indoor air, and meet the related specification standard.
