At present, the main methods of removing water, ice and snow from the window glass include mechanical and electric heating, both of which have their own advantages and disadvantages. The mechanical type is mainly a wiper, which can effectively remove rainwater, snow, etc. on the outer surface of the glass of the car body, but it is helpless for the water mist on the inner surface of the front windshield of the vehicle and the icing on the outer surface; the electric heating type is through the resistance wire embedded in the glass. Through electric heating, the water vapor, ice and snow attached to the inside and outside of the glass are melted and evaporated, but the resistance wire is generally an opaque material, which will partially block the driver's line of sight, so it is currently only used for the glass at the rear of the car body windows, but cannot be used for rearview mirrors and front windshields. In addition, compared with the mechanical heating method, the electric heating method has slower response and slower effect.

Based on the deficiencies of traditional glass for removing water, ice and snow, this utility model proposes a glass with a deicing device based on graphene. Embedded in the glass of the car body, it has the advantages of rapid heating to remove water, ice and snow without affecting the driver's sight.
