Further, the photocatalytic filter is composed of a metal grid coated with a nano-scale titanium dioxide coating.

Further, the sensing system is arranged between the air inlet and the air filter system.

Further, the air filtration system sensing system includes a smoke sensor, an odor sensor and a buzzer.

Further, the sterilization system is arranged at the rear side of the air filtration system, and the cross-flow fan is arranged at the rear side of the air filtration system.

Further, the sterilization system includes a liftable uV germicidal lamp and a liftable infrared lamp.

Further, the air outlet is arranged on the upper part of the housing.

Further, the upper part of the housing is provided with buttons and a display screen.

Beneficial effects: an air purifier of the utility model has a simple structure. Driven by a cross-flow fan, the indoor air passes through the pre-filter cotton, high-efficiency air filter, activated carbon filter screen, UV lamp, and photocatalytic filter screen in order to sterilize, The purified air is sent to the room through the air outlet; at the same time, the adjustable UV sterilizing lamp and the adjustable infrared lamp can be used alone to sterilize, dehumidify, and treat the indoor air.
