Abstract

The utility model discloses an electric heating cushion, which comprises a fiber layer and an electric heating wire. The electric heating wire is distributed inside the fiber layer in a snakelike form and connected with a power line, a control adjusting switch is arranged on the power line, the electric heating wire is connected in series with the control adjusting switch, an aluminum foil layer is spread outside the electric heating wire and covers the electric heating wire, the inner side of the aluminum foil contacts with the electric heating wire, the outer side of the aluminum foil contacts with the fiber layer, the aluminum foil has fine heat conductivity and is capable of quickly absorbing heat of the electric heating wire, the heat is quickly conducted to the whole aluminum foil layer and conducted to a human body through the fiber layer, and the safety hidden hazard of over-high local temperature can be avoided. Further, the aluminum foil made of metal is capable of shielding electromagnetic radiation emitted by the electric heating wire in operation, thereby benefiting body health.

Description

A kind of electric heating pad

Technical field

The utility model relates to a kind of electric heating pad.

Background technology

The electric heating pad, comprise electric heating seat cushions, electric mattress etc., traditional electric heating pad is at fibrage laid inside heating wire, generate heat after the heating wire energized, heat conducts to human body by fibrage, but fibrage poor thermal conductivity, reach desirable heating purpose, then need to strengthen the power of heating wire, it is too high so just to have caused fibrage directly to contact the portion temperature of heating wire, and the portion temperature that does not contact with heating wire is lower, when the heating wire temperature is too high, not only can cause the human body discomfort, also have the danger of breaking out of fire; In the use simultaneously, heating wire has electromagnetic radiation, and traditional electric heating pad can not electromagnetic radiation shielding.

The utility model content

The purpose of this utility model provides a kind of electric heating pad, and mat is temperature equalization in use, has prevented the generation of fire incident effectively, has the effect of electromagnetic radiation shielding simultaneously.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of electric heating pad, comprise fibrage and heating wire, heating wire is the snakelike fibrage inside that is distributed on, and heating wire links to each other with power line, and is provided with control adjusting switch on power line, and heating wire is connected with control adjusting switch, outside at heating wire, tiling one deck aluminium foil also wraps up heating wire, and the aluminium foil medial surface contacts with heating wire, and lateral surface contacts with fibrage.

The beneficial effects of the utility model are:

The thermal conductivity of aluminium foil is good, can promptly absorb the heat of heating wire, and conduct to whole aluminium foil layer fast, conduct to human body by fibrage again, avoided the too high potential safety hazard of local temperature, simultaneously, aluminium foil is a metal material, the electromagnetic radiation of sending in the time of can shielding heating wire work is of value to healthy.
