A composite health-care electric blanket

Abstract

The invention discloses a composite health care electric blanket. The composite health care electric blanket includes an electric blanket body; the lower surface of the electric blanket body is provided with a buffer support layer; the upper surface of the electric blanket body is provided with a silica gel layer; a surface of the silica gel layer forms a far infrared negative ion powder layer through physical vapor deposition; a heating wire is arranged in the electric blanket; the heating wire is electrically connected to an over-temperature protection element; the heating wire includes a plurality of heating rings and metal nickel plating aluminum foils arranged on the outer peripheries of the heating rings, wherein the heating rings have different sizes, have the same circle center, and are wave-shaped; the over-temperature protection element includes U-shaped conductive composite core wires which are connected in an end to end manner, and silica gel insulating layers arranged on the outer peripheries of the conductive composite core wires. The composite health care electric blanket is good in hand feeling, is long in service life, is high in voltage resistant performance, is reliable, is good in warming effect, can kill bacteria, diminish inflammation, and release negative ions, and is powerful in heath care function.

Description

technical field [0001] The invention relates to the technical field of heating products, in particular to a composite health care electric heating blanket. Background technique [0002] With the improvement of people's living standards, the quality requirements for daily necessities continue to increase. In autumn and winter, many people who are afraid of the cold need to use electric blankets, and some even use them for pets. In addition to requiring adjustable and controllable temperature, automatic constant temperature, etc., there are often local wrinkles due to abnormal operations. Or the partial pressure is too heavy, or the multi-layer folding causes the local or overall temperature of the electric blanket to be too high. If it cannot be avoided in time, it will cause the electric blanket to overheat and catch fire, causing a fire. [0003] At present, the positive temperature coefficient PTC (Positive Temperature Coefficient) characteristic can be exhibited in the c...
