Embodiment one
As shown in Figure 1 and Figure 2, the utility model embodiment one provides a kind of antifog glass 100 of camera, the antifog glass
Glass 100 is equivalent to the protective cover of lens assembly 400 in following cameras, is formed in the front end of lens assembly 400.It is described antifog
Glass 100 includes glass panel 110, and the shape of glass panel 110 is depending on actual needs, such as round, rectangular, planar shaped
Or curved form etc..The glass panel 110 has silver slurry layer 120, silver paste towards silk-screen on an end face of lens assembly 400
The periphery that layer 120 is formed in 110 end face of glass panel, it is annular in shape and there is a notch 130, on silver paste layer 120, corresponding
The both ends of notch 130 are equipped with anode and cathode, are plugged with metal pin 140, metal pin respectively on the anode and cathode
The heating of glass panel 110 is realized after 140 energizations, the metal pin 140 can be realized logical with the circuit board electrical connection of camera
Electricity Functional.When the temperature difference of glass panel 110 is larger, apply voltage to 140 both ends of metal pin, silver paste can quickly be sent out
Heat can effectively remove the water mist on glass panel 110.The antifog glass 100 is applied on camera, and structure is simple, at low cost,
