Abstract
The utility model relates to an electric heating pad, which comprises an outer housing, an heat insulating layer and an electric heating sandwich layer arranged in the outer housing, wherein the electric heating sandwich layer is provided with electric heating lines and power supply wires; the electric heating lines and the power supply wires all adopt carbon fibers, alloyed threads or composite metal fibers, the power supply wires consist of five to eight strands, each strand consists of a plurality of alloyed threads, carbon fibers, or composite fibers with 3 to 15 Mu m diameters, the strands are arranged on the two sides of the electric heating sandwich layer, power lines are connected at one ends of the power supply wires on one side, a plurality of electric heating lines are arranged on the electric heating sandwich layer between two power supply wires in wave shapes, and the two ends of each electric heating line are electrically connected with the power supply wires. The utility model solves the problems that the existing electric heating pad adopts silver jacketed wires as the internal power supply electric conduction lines, so when the electric heating pad is used on soft seats, fire phenomena happen constantly on the hard silver jacketed wires under the effect of the pressure of an user, and sometimes fire hazards are even caused, etc.
Description
Technical field
The utility model relates to a kind of electric pad, particularly a kind of can folding arbitrarily, the electric heating pad that inner lead can not be struck sparks or fracture.
Background technology
Electric heating is lined with a variety of, use very wide, as all can above being used in home seating, automobile etc., but the conventional electric heating pad all is to adopt the power supply conductivity line of silver jacketed wire as inside, so when on softer seat such as automobile, using, because the hardness of silver jacketed wire is bigger, Chang Haosheng spark phenomenon under the effect of user's pressure, that have even initiation fire is so the existing potential safety hazard of existing electric heating pad is the problem that a needs solves always.
Summary of the invention
Goal of the invention: the utility model provides a kind of electric heating pad, its purpose is to solve existing electric heating pad and adopts the power supply conductivity line of silver jacketed wire as inside, when this electric heating pad uses on softer seat, the phenomenon that harder silver jacketed wire is often struck sparks under the effect of user's pressure, the problem that has even aspect such as initiation fire exists.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of electric heating pad, this heating resistance pad comprises overcoat, is arranged on heat-insulation layer and electric heating sandwich layer in the overcoat, it is characterized in that: the electric heating sandwich layer is provided with electric heating wire and power lead; Electric heating wire and power lead all adopt carbon fiber, alloy silk or composite metal fiber, power lead is formed by 5～8 strands, per share is that the thick carbon fiber of 3～12 μ m, alloy silk or composite metal fiber are formed by many diameters, they are arranged on the both sides of electric heating sandwich layer, one end of the power lead of every side all is connected with power line, many electric heating wires are the zigzag waves shape wave and are arranged on electric heating sandwich layer between two power leads, and the two ends of every electric heating wire are electrically connected with power lead.
It is carbon fiber, alloy silk or the composite metal fiber of 120～180 Ω/m that above-mentioned electric heating wire adopts resistance.
It is carbon fiber, alloy silk or the composite metal fiber of 3～15 Ω/m that above-mentioned power lead adopts resistance.Advantage and effect: by the enforcement of technical solutions of the utility model, can solve well in the existing bedding, have only electric blanket can carry out electric heating, and there is the use of can not switching on for a long time in it, inapplicable all crowds, folding back is broken string easily, initiation fire, and heating region can only be realized single temperature, can not the subregion heating etc. the problem that exists of aspect.
Overcoat and electric heating sandwich layer that the utility model product adopts can adopt far-infrared electric cloth, and its pulling force is strong, ageing-resistant, can fold arbitrarily, can use on any bed, have following characteristics:
1. environmental protection: this product can adopt DC-voltage supply, and no electromagenetic wave radiation, influence electricity produce, but the continuous high temperature use does not have any injury.Be applicable to the demand of different people, particularly the elderly and minor;
2. safe and reliable: low-voltage (6-24V) is powered, and can finish gold and eliminate the fearness humidity, and misgivings, especially children's electric blankets such as fearness electric shock can be used the 6-8V powered battery, and 100% is relieved;
3. establish temperature voluntarily: but design temperature is temperature automatically controlled on temperature, has also set up best sleep switch, cuts off foot's heating power supply in addition when sleeping, makes the sleep quality environment be in warm, comfortable, best temperature environment all the time;
4. durable in use: the local damage of this product does not influence heating effect, heater useful life and cloth are equal, owing to adopt thicker carbon fiber, alloy silk or composite metal fiber as power lead, thereby do not exist traditional silver jacketed wire that the danger of sparking initiation fire takes place.
