Ozone disinfecting device and method for using same for disinfection

An ozone disinfecting device comprises a shell, ozone generators, ozone reduction ultraviolet lamps, a draught fan, a dust removing module, a sliding rail and a control circuit board. The power of the ozone reduction ultraviolet lamps is set to be P>/=0.25*Q*V/(K1*K2*T). A disinfecting method of the ozone disinfecting device comprises the following steps that firstly, the ozone disinfecting device and an article to be disinfected are put into a sealed disinfecting space, and the ozone generators and the draught fan are switched on for disinfection; secondly, after the disinfecting time is up, the ozone generators are switched off, the ozone reduction ultraviolet lamps are switched on, and the draught fan is maintained in operation; thirdly, after the ozone reduction time is up, the draught fan and the ozone reduction ultraviolet lamps are switched off. According to the ozone disinfecting device and the disinfecting method, the concentration of ozone can be selected according to the disinfecting and odor removing requirements, and thus the disinfecting and odor removing effects are guaranteed; the power of the ultraviolet lamps is selected according to the size of the space, the concentration of ozone for disinfection and the ultraviolet radiation conditions so as to quickly achieve the ozone reduction purpose.
