AI Technical Summary
In existing heated mattresses, the double-helix heating wires are prone to breakage, which can cause the filling layer to be burned through by high temperatures and pose a safety hazard.
A flexible electric heating film is sandwiched between the foamed comfort layer and the foamed insulation layer, and the wires, PCB board and power supply are placed between the foamed insulation layer and the air cushion. The mattress cover and the edge of the air cushion are sewn together with visible stitching, resulting in a safe and reliable structure.
This improves the safety performance of heated mattresses, reduces the unpleasant experience of hard objects such as wires, and enhances user comfort and satisfaction.
