AI Technical Summary
Existing electric heating films in flexible heating appliances can cause localized high temperatures due to partial coverage or folding, posing risks of product damage and burns. Furthermore, multi-point temperature control processes are complex and costly.
Two or more conductive lines are set in each heating zone of the electric heating film as heating elements or temperature measuring elements. The conductive lines are arranged in parallel or cross directions in the same or different insulating layer planes to achieve real-time and accurate temperature measurement and control throughout the entire area.
It achieves real-time and accurate temperature detection across the entire heating zone of the electric heating film, avoiding localized high temperatures, reducing the risk of product damage and burns, while also simplifying the process and reducing costs.
