Description

The flat-plate heating device

Technical field

The utility model relates to a kind of electro-heat equipment, relates in particular to a kind of soft flat-plate heating device of collapsible use.

Background technology

In life, usually use electric heater unit, make conductor and the heating of electric current by having resistance, this heater often uses plain conductor as conductor, but when electro-heat equipment is used for some special products such as electrically warmed shoes, electric blanket, less because of the power of needs, and require lead lighter, plain conductor just must be done very carefully, in using folding process, fracture easily, and plain conductor is not easy to and the cloth secure bond.

The utility model content

The purpose of this utility model is in order to provide a kind of being convenient to make, and is tough and tensile durable, can often fold and carry and non-damageable flat-plate heating device.

In order to realize above-mentioned purpose, flat-plate heating device of the present utility model comprises the reticular fibre carrier, be covered in the conductive coating of reticular fibre carrier surface and be covered in the insulating barrier of conductive coating outside.

Above-mentioned reticular fibre fiber material that carrier uses is a kind of flame-proof heat-resistant fiber.

Above-mentioned conductive coating is a conductive ink layer.

Above-mentioned insulating barrier is a silicon rubber coating.

Also can use insulation film to replace above-mentioned insulating barrier, be coated on the outer surface of the reticular fibre carrier that scribbles conductive coating.

Above-mentioned reticular fibre carrier edge end is provided with conductive strips, and conductive strips lead to the wiring lead.

Relevant detailed content of the present utility model and technology are described as follows with regard to conjunction with figs. now.

Embodiment

Please refer to Fig. 1, Fig. 2 and shown in Figure 3, flat-plate heating device of the present utility model comprises the netted reticular fibre carrier 1 of anti-breaking tension, reticular fibre carrier 1 comprises horizontal fibers striped 11 and perpendicular fiber striped 10, this reticular fibre carrier 1 surface is soaked to be coated with and is wrapped with the conductive coating 2 that one deck is used to conduct electricity, and conductive coating 2 outsides are coated with the insulating barrier 3 of heat conduction, wear-resisting and insulation.

Reticular fibre carrier 1 need have sufficient tension, fire-retardant, high temperature resistant and pliability, thereby this reticular fibre carrier 1 fiber material that uses is a kind of flame-proof heat-resistant fiber, for example can use natural fibers such as cotton textiles, silk, polyester, poly-ammonia, organic fibers such as plane heat resistance fiber net, inorfils such as glass fibre, perhaps above various fibrous blend fibres.

The mesh shape of reticular fibre carrier 1 can have various ways, both can make the grid that is interwoven by fiber striped anyhow, also can be diagonal screen, the involute net.

The material of above-mentioned conductive coating 3 generally uses conduction and heat conduction all to be relatively easy to conductive ink layer.

For making insulating barrier 3 of the present utility model have good heat conduction, waterproof and anti-flammability, this insulating barrier 3 is the silicon rubber dope layer.

As shown in Figure 4, for this flat-plate heating device and external power supply are electrically connected, reticular fibre carrier 1 left and right edges end at this flat-plate heating device is provided with conductive strips 8, conductive strips 8 are to be woven mutually by plain conductor and reticular fibre carrier 1 to form, conductive strips 8 lead to wiring lead 5, wiring lead 5 is connected with extraneous power supply, because the resistance of conductive strips 8 is less, thereby electric current can guarantee that the voltage between the two ends, the left and right sides of this flat-plate heating device keeps identical, makes this flat-plate heating device heating more uniform and stable.

As shown in Figure 5, the conductive coating 2 of flat-plate heating device of the present utility model also can use insulation film 6, this flat-plate heating device envelope is located at this insulation film 6, make this flat-plate heating device have better waterproof ability and better security performance, this insulation film 6 adopts soft heat conductive silica gel usually.

As shown in Figure 6, structural representation for the netted fiber carrier 1 of the utility model flat-plate heating device, for making the reticular fibre carrier more firm, the horizontal fibers striped 11 of this reticular fibre carrier is the sub-thread form, perpendicular fiber striped 10 be a double-twisted structure, perpendicular fiber striped 10 the Box junction place with twist around horizontal fibers striped 11.

The flat-plate heating device that utility model relates to, because the netted traction-resistant fibre material that adopts good toughness is as reticular fibre carrier 1, outer soaking respectively at reticular fibre carrier 1 wrapped up in conductive coating 2 and insulating barrier 3, perhaps use insulation film 6 to replace insulating barrier 3, thereby be convenient to make, reduce cost, the cutting easily of reticular fibre carrier, after being convenient to sew up with soft cloth, the folding use have ease for use preferably, and this flat-plate heating device is convenient to be connected with power supply, heating is even, and heating property is also more stable.
