Abstract
The utility model belongs to the technical field of electric heating, particularly a safety automatic temperature controlled electric blanket without electrical pollution. The utility model is mainly composed of automatic temperature controlled macromolecule electric heating cables (1), (2), (3) and (4), an electric blanket fabric (5), a power supply box (6) and a power supply lead (7). When electrified, the electric heating cables can change electric energy into heat energy and any point on the electric heating cables can automatically control temperature according to the inherent positive temperature coefficient characteristic of the electric heating cables, solving the problem that the electric blanket at present is not provided with temperature control and fire is easy to happen in abnormal use and realizing the automatic temperature control and fire safety of flexible electric heating products, such as the electric blankets, etc.
Description
The utility model belongs to field of electric heating, the temperature automatically controlled no electropollution electric blanket of particularly a kind of safety-type.
At present, electric blanket and other electric heating flexible product, heating are flexible spiral electric heating nickel filament structure, and its shortcoming is, warping resistance is poor, are difficult to realize automatic temperature-adjusting control, when fractureing soon, localized hyperthermia occurs, produce the electric arc fabric that ignites and cause fire.Filament forms the aerial radiation structure and causes electromagnetic pollution.
The purpose of this utility model provides the temperature automatically controlled no electropollution electric blanket of a kind of safety-type, solves above shortcoming.Its principle is the characteristic of expanding with heat and contract with cold of utilizing macromolecular material intrinsic, and the realization temperature is controlled automatically and adopted parallel-connection structure to realize non-cracking, does not therefore have localized hyperthermia and electropollution, has satisfied electric heating fabrics safety and temperature automatically controlled requirement.
The utility model is achieved in that it is by temperature automatically controlled high molecular electrothermal cable (1), (2), (3), (4), electric blanket fabric (5), power pack (6), power supply lead wire formations such as (7), wherein temperature automatically controlled high molecular electrothermal cable (1), (2), (3), (4), adopt macromolecule conducting material (3) as the electric heating transition material, conductive material 3 is formed by even conductive doped powder in the macromolecular material, and the outer one deck high strength insulation macromolecular material that coats of conductive material (3) is as insulation course (4), conductive material (3) clad metal lead (1), (2), form the shunt cable structure, lead (1), (2), be connected with power pack (6), be connected with electrical network, constitute the temperature automatically controlled no electropollution electric blanket of complete safe type by power supply lead wire (7).Wherein, temperature automatically controlled characteristic realizes by the macromolecular material principle of expanding with heat and contracting with cold, when the electric blanket energising, the heating cable temperature raises, when reaching design temperature, conducting polymer composite expands, and conduction powder spacing is elongated, some conductive paths disconnect, the heating cable resistance value raises, and power descends, and electric blanket temperature reduces, be stabilized at last on the design temperature, it is temperature automatically controlled to form the electric blanket arbitrfary point.Adopt the heating cable structure, lead (1), (2) are that stranded copper wire is through anti-oxidation processing, form parallel-connection structure by the conducting polymer composite coating, contact area is big, and electric current does not just pass through from this when local loose contact, therefore can not form localized hyperthermia, cause fire.
Conductive lead wire (1), (2) can accomplish good the contact with power pack (6), have solved nickel filament and have been difficult to the good problem that contacts with power pack (6).
Adopt the electric blanket of heating cable structure, form planar heating, stray inductance, electric capacity is very little, has formed no electropollution electric blanket.Power supply can be the urban network electricity source, also can be special lower security power supply
Accompanying drawing is the temperature automatically controlled no electropollution electric blanket structural representation of safety-type of design.(1), (2) are the anti-oxidation copper wire lines of multiply, and (3) are the high molecular electrothermal transition materials, and (4) are polymeric dielectric layers, and (5) are the electric blanket fabrics, and (6) are power packs, and (7) are power supply lead wires.
Claims (3)
1. the temperature automatically controlled no electropollution electric blanket of safety-type is by temperature automatically controlled high molecular electrothermal cable (1), (2), (3), (4), electric blanket fabric (5), power pack (6) and power supply lead wire (7) constitute, and it is characterized in that: in electric blanket fabric (5), be distributed with temperature automatically controlled high molecular electrothermal cable (1), (2), (3), (4) are as heating, be connected with power supply with power supply lead wire (7) by power pack (6), constitute electric blanket.
2. according to the temperature automatically controlled no electropollution electric blanket of the described safety-type of claim 1., it is characterized in that: temperature automatically controlled high molecular electrothermal cable (1), (2), (3), (4), as the electric blanket electrothermal conversioning element, by conductive lead wire (1), (2), high molecular electrothermal layer (3), polymeric dielectric layer (4) is formed, conductive lead wire (1) wherein, and (2) are more than two or two.
3. according to the temperature automatically controlled no electropollution electric blanket of the described safety-type of claim 1., it is characterized in that: electric blanket fabric (5) can be a nonwoven fabrics, cotton.
