Example 1

Referring to fig. 1-2, an electric blanket capable of preventing overheating by folding comprises a blanket main body 1, wherein a plurality of heating wires 3 are arranged inside the blanket main body 1, insulating outer skins 2 are welded outside the heating wires 3, cavities are arranged inside the insulating outer skins 2, magnesium oxide particles 7 are arranged in the cavities of the insulating outer skins 2, rubber strips 6 are arranged on the inner walls of the two ends of the insulating outer skins 2, the cavities are arranged inside the insulating outer skins 2, the magnesium oxide particles 7 are filled in the cavities, the magnesium oxide particles 7 have a heat conduction and insulation function, when the electric blanket is folded, due to the fact that fillers are arranged, folding gaps are widened, and abrasion of the insulating outer skins 2 caused by folding is relieved to a certain extent when the electric blanket is folded.

Wherein, blanket main part 1 one side welding has

electric wire

4, 4 one end welding of electric wire has plug 5, when the electric blanket is folded, rubber strip 6 is crooked, because rubber itself has certain tension, when the folding of rubber strip 6, rubber strip 6 has tension because the compression in one side of folding department, the opposite side has elasticity owing to the extension, prevents the electric blanket and closely laminates on folding department both sides to prevented heating wire 3 when folding, because of folding angle is too big, lead to heating wire 3 at the resistance grow, generate heat too much problem.
