Abstract
A fog-proof device for evaporating fog from a camera's lens includes a glass covering a front surface of the lens, and a light-shielding cylinder mounted to the glass. The light-shielding cylinder defines a through hole. A zigzagging heat-generating portion is formed along a circumference of the light-shielding cylinder, and two ends of the heat-generating portion are separated by a gap. Ends of the heat-generating portion at opposite sides of the gap are electrically connected to two power wires.
