Description

Transparent heating film Technical Field The utility model relates to the technical field of heating films, in particular to a transparent heating film. Background Because of the temperature difference between the inside and the outside, fog is easy to form on the glass, the sight is easy to be blocked, and particularly, the damage is larger in the moving process, for example, the front windshield of an automobile is influenced once fog is formed. For the non-mobile type (such as a showcase, a glass window of a home or a factory, etc.), most of the existing methods are not processed, but after fog is formed, light rays, sight lines, etc. are shielded, water drops are formed, and water stains are formed on the glass for a long time; At present, a transparent electric heating film layer is arranged on a windshield, and two conductive motors are arranged at the edge of the electric heating film layer, for example, the Chinese utility model application number is 94230063.7, and the mode can play a role in preventing fog and defrosting, but has some defects.
