Abstract

The utility model relates to a flexible heating unit which comprises a conductive layer and power cords; the conductive layer is arranged between a first protective layer and a second protective layer and is jointed with the first and second layers into a whole, the conductive layer is a flexible fabric woven by metal yarns and common yarns, the metal yarns are orderly woven between the adjacent 2-35 warp common yarns and the adjacent 2-35 weft common yarns to form the cross-woven warp and weft metal yarns, terminals are respectively led out from the metal yarns on both lateral edges of the conductive layer, and the power cords are respectively fixed on the two terminals and extend out of the conductive layer. The flexible heating unit accordingly solves the problems of poor flexibility, easy oxidation and water-washing damage found in resistance wire and also overcomes the defects of poor softness and rigidity of carbon fiber. Besides, the flexible heating unit has good practical adaptability such as strength and deformation, has good softness and can be fabricated into heating units of various electric heating clothes, cushions and quilts, also has low cost, simple manufacturing technique and is suitable for industrial production.

Description

Flexible heating element

Technical field

The utility model relates to a kind of heater, specifically relates to a kind of flexible heating element.

Background technology

In daily life, it often all is only to consider its aesthetic property and comfortableness that people wear dress ornament, and its function is relatively single always.In recent years, lifting along with people's quality of life, requirement to various lives is also just more and more higher, thereby can be increasing to the dress ornament demand of human body heating health care, meanwhile, the heater research that is used for dress ornament is in popular position with invention always, make a general survey of domestic correlative study, on the whole all use at present the thermo electric material of resistance wire or carbon fiber wire and so on, specific practice is to be fixed in the cloth body and to form plane to move widely different mode by design length, thereby reach the purpose of conduction heat supply, but these technology are accepting aspect the practice test, often not enough.Resistance wire is a kind of metal material, and its anti-performance that fractures must be subjected to certain limitation, easily oxidation, and rotproofness is poor, not water-fast again washing, useful life is short, and thermal conversion rate is low, is easy to generate electromagnetic wave; Carbon fiber wire is a kind of hard material, and fracture and loose contact, manufacturing cost height appear in its softness and poor rigidity easily.Thereby the dealer further uses resistance wire or carbon fiber wire directly to inweave to form heater in the fabric, it not only exists weaves the defective of being obstructed in difficulty and the design, and poor ductility, can't cooperate physical activity and bending, in folding or washing, even frangibility in the everyday general purpose process, make the permanent inefficacy of conducting function of heater, many weak points are still arranged, do not reach desirable practical requirement.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of being easy to make, and cost is low, and is soft and light, and folding is washable, heat efficiency height, the flexible heating element of long service life.

In order to achieve the above object; the utility model is by the following technical solutions: a kind of flexible heating element; comprise conductive layer and power line; described conductive layer is sandwiched in first protective layer and middle being superimposed with each other of second protective layer is integral; this conductive layer is the soft fabric that is formed by Metal Yarns and common yarn co-woven; described Metal Yarns is separated by between the 2-35 root and the layout in order between the 2-35 root of being separated by of every adjacent broadwise common yarn at the every adjacent warp-wise common yarn of fabric; form warp-wise and broadwise Metal Yarns and intersect layout mutually; and in draw terminals respectively on the Metal Yarns on described conductive layer dual-side edge, the fixed power source line extends outside the conductive layer respectively on two terminals.

Described Metal Yarns resistance value is 0.02 Ω-600 Ω for every meter.

Described first protective layer and second protective layer are respectively a kind of compositions that is provided with PUR, polyamine Ethyl formate, polyvinyl chloride or PET with the one side of common fabric, and its shape size is suitable with conductive layer.

The utility model compared with prior art, have following advantage and beneficial effect: because the soft fabric that conductive layer forms by Metal Yarns and common yarn co-woven, can keep fabric original physical properties and style constant, make conductive layer rub again and can fabric not take place in the process and Metal Yarns is peeled off mutually in bending, easy fracture more not, it is poor not only to have solved the resistance wire fold resistance, easily oxidation, not laundry-resistant problem, and overcome the defective that carbon fiber wire softness and poor rigidity and heater plane convex-concave have foreign body sensation.Metal Yarns mutual intersection layout in fabric simultaneously is equal to electric each other contact, thereby can not produce the electromagnetic wave of harmful to human, also can significantly improve the heat efficiency of unit are.In addition, the utility model also has the adaptability that intensity, deformation etc. are used, and is convenient to be processed into difformity, and is applied widely, can be made into the heater of articles for use such as various electric heating dress ornaments, seat cushion and bed clothes, its flexibility and good permeability, heat efficiency height heats up rapidly, heating evenly, cost is low, and manufacturing process is simple, easily industrialization.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

See also Fig. 1 and in conjunction with Fig. 2; a kind of flexible heating element; comprise conductive layer 2 and power line 5; the centre that conductive layer 2 is sandwiched in first protective layer 1 and second protective layer 3 is superimposed; and be bonded into one by the direction of arrow shown in Fig. 1; the shape size of first protective layer 1 and second protective layer 3 is suitable with conductive layer 2; they select common fabric respectively for use; a coating hot-melt adhesive at common fabric; the polyamine Ethyl formate; the protective layer of a kind of composition of polyvinyl chloride or PET; to play insulation and waterproof effect; conductive layer 2 is the soft fabrics that formed by Metal Yarns 6 and common yarn 7 co-woven; it is the long filament that the substrate passed plating acrylic acid and copper sulphate are spun into that the Metal Yarns 6 of present embodiment is selected from acrylic fibers or nylon fibre; the fiber number of long filament is less than 500D, and every meter of its resistance value is between 0.02 Ω-600 Ω.Weave on looms when making, Metal Yarns 6 is separated by between the 2-35 and the layout in order between the 2-35 of being separated by of every adjacent broadwise common yarn at the every adjacent warp-wise common yarn of fabric, form warp-wise and broadwise Metal Yarns 6 intersection layout mutually, can keep fabric original physical properties and style constant, be equal to electric each other contact again, can not produce the electromagnetic wave of harmful to human, also can significantly improve the heat efficiency of unit are.On the Metal Yarns 6 on conductive layer 2 dual-side edges, draw terminals 4 respectively, on two terminals 4 respectively fixed power source line 5 extend that conductive layer 2 is outer to be imported with power supply source, its heat efficiency height, heat up rapidly, heating evenly, applied widely, can be made into the heater of articles for use such as various electric heating dress ornaments, seat cushion and bed clothes.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from invention thought; various modification and improvement that those of ordinary skills make the utility model should fall in the protection range of the present utility model, and the content that the utility model is asked for protection all is documented in claims.
