NOVELTY - The utility model claims a virus-killing air freshener, comprising a shell; the shell is upper end with an air outlet; the lower end is provided with an air inlet; the shell is further provided with a plug and a switch; the middle of the shell from bottom to top is provided with a first filter layer, an ultraviolet lamp and a titanium dioxide net layer; an electrostatic adsorption layer and a nano-titanium dioxide nano graphene layer. The utility model primarily filters the air by setting HEPA filter screen and medical nonwoven fabric, so as to realize the large particle and dust object in the air can be blocked, then by setting the ultraviolet lamp and titanium dioxide net layer of the photocatalyst layer, realizing superoxide killing the virus in the air; and the titanium dioxide net layer itself can realize the second-stage filtering, further through setting the electrostatic layer and nano-titanium dioxide and nano graphene layer to realize the air after sterilizing and sterilizing the virus four-stage filtering, at last, discharging the purified high quality air, realizing the circulation of air quality.
