When the movable plate 33 is aligned with the fixed plate 32, the shielding member 3 is in an illuminated state, and the ultraviolet rays emitted from the light source 2 can pass through the movable plate 33 and the fixed plate 32 to sterilize the external environment. When the movable plate 33 and the fixed plate 32 are offset, the shielding assembly 3 gradually enters a closed state until the offset distance between the movable plate 33 and the fixed plate 32 is maximum, the shielding assembly 3 is completely closed, and at the moment, the ultraviolet rays emitted by the light source 2 are completely shielded by the movable plate 33 and the fixed plate 32, so that the light source 2 is lost indoors.
