The irradiation lamp and the fan both adopt safe voltages, the USB interface mode is preferably used for switching on the power supply, the ultra-low safe voltage is adopted, electric leakage or fire accidents can not occur, the safety is enhanced, and the silencing effect is good. The irradiation lamp can emit visible light or ultraviolet light to emit light as a main function, and a low-power consumption LED lamp can be used.

When the deodorizing box is used, the deodorizing box is placed at a place which is not in the way near the wall edge or the corner, such as under a bed, a table and the like, the air inlet faces indoors, and the air outlet faces the wall or the corner. The connecting socket is connected with a power supply, the irradiation lamp in the box body is lighted, the fan is started, indoor air is pumped in from the air inlet, and the indoor air is discharged from the air outlet, so that forced circulation of the indoor air is formed. When the indoor air passes through the dust removing filter screen, dust in the air is filtered, and when the indoor air passes through the deodorizing filter screen, the deodorizing agent fully contacts the modified photocatalyst titanium dioxide deodorizing agent to remove peculiar smell in the air under the action of illumination, so that the effect of removing the indoor peculiar smell is achieved.
