Abstract
An electric blanket based on a graphite heat conductor comprises an electric blanket body; heating cables are arranged in the electric blanket; two pieces of graphite paper are arranged on two sides of the heating cables; and double-sided adhesive is arranged between the two pieces of graphite paper. According to the electric blanket based on the graphite heat conductor, which is provided by the utility model, through the arrangement of a graphite heat conductor, the problems of energy waste and potential safety hazards of the traditional radiating fins are solved; since graphite material has very strong heat conductivity (the heat conductivity of the graphite material even can be better than that of copper or aluminium after the graphite material is processed), in a short time (about 5 seconds) that the heating cables generate heat, the graphite heat conductor can transfer the heat 100 mm away, and the heating effect is not influenced even if the interval between the heating cables inside the electric blanket is more than 150 mm; besides, the graphite heat conductor, namely the graphite paper in the electric blanket, can spread heat quickly, so that the phenomenon that heat accumulates near the heating cables can be avoided, and then dangerous conditions are prevented.
Description
Technical field
The utility model relates to a kind of electric blanket, particularly a kind of electric blanket based on the graphite heat conducting body.
Background technology
Traditional electric blanket is a kind of contact electric heating appliance, and it is dish snake shape with soft cable-styled heating cable (being resistance wire) special, that insulating properties reach standard and inweaves or sew up in the woollen blanket, evolution of heat during energising.But traditional electric blanket also has following problems: one of which, the heat build-up phenomenon of traditional electric blanket has been wasted electric energy greatly, mainly show in order to reach uniform heating, need with heating cable arrange very close; In addition, traditional electric blanket also exists huge potential safety hazard, because, when heat build-up acquires a certain degree, may cause near the temperature of heating too high, thereby on fire, this example happens occasionally in the electric blanket use.
Summary of the invention
The utility model technical problem to be solved provides a kind of electric blanket based on the graphite heat conducting body, can the heat that heating produces be transmitted rapidly and open, and eliminates safe hidden trouble.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of electric blanket based on the graphite heat conducting body, comprise electric blanket, and be provided with heating cable in the electric blanket, the heating cable both sides are provided with graphite paper.
Also be provided with double faced adhesive tape between the described graphite paper.
Described graphite paper opposite side also is provided with single face glue.
In the described single face glue, having one deck at least is insulation single face glue.
Described single face glue is PET film single face glue.
A kind of electric blanket that the utility model provides based on the graphite heat conducting body; Through the graphite heat conducting body is set; Overcome the problem that traditional fin exists energy waste and potential safety hazard two aspects; Because graphite material has extremely strong thermal conductivity (process is handled afterwards even can be surpassed copper and aluminium), therefore, in the blink of heating cable generation heat (greatly within five seconds); The graphite heat conducting body just can be communicated to heat beyond the 100mm; So it is above and do not influence heating effect that the inner heating cable of the utility model can reach 150mm at interval, this distance be existing electric blanket internal heat generation cable at interval more than three times, according to heating power formula P=I
2R and resistance formula R=σ L/S can know; Electrical power P is directly proportional with the resistance wire length L; That is to say the utility model in theory power consumption can be reduced to 1/3rd of electric blanket power consumption of the prior art, therefore the utlity model has energy-efficient advantage; In addition, can rapidly heat be scattered, therefore near heating cable, the phenomenon of heat build-up can not occur, thereby avoid the generation of unsafe condition because the graphite heat conducting body is a graphite paper in the utility model.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
In Fig. 1, Fig. 2, a kind of electric blanket based on the graphite heat conducting body comprises electric blanket 1, is provided with heating cable 2 in the electric blanket 1, and heating cable 2 both sides are provided with graphite paper.As shown in Figure 2; Be respectively ground floor graphite paper 7 and second layer graphite paper 5 in this example and be positioned at the both sides of heating cable 2, through graphite paper conduction heat, two-layer up and down graphite paper is the key of the utility model; After 2 heating of the heating cable in the middle of the graphite paper; Heat at first is delivered on the graphite paper that contacts with heating cable 2, then along the surface of graphite paper to around transmit, till the surface temperature of whole graphite paper is evenly; Graphite paper is commercially available product, for example originates in flexible graphite paper or doped graphite paper that section's perseverance in the Yichang reaches graphite limited company.Adopt after the scheme of graphite paper conduction heat; Heating cable 2 in the utility model can adopt the spacing B of broad, for example the spacing of 150mm when adopting like the arrangement mode among Fig. 1; Can reach and the identical heating effect of prior art 45mm spacing; Therefore also practiced thrift raw material,, also saved electric energy owing to shortened the length of heating cable 2.
The scheme of optimizing is also to be provided with double faced adhesive tape 6 between the described graphite paper.The effect of double faced adhesive tape 6 has two, on the one hand is to be used for ground floor graphite paper 7 and second layer graphite paper 5 are combined, and is fixing heating cable 2 on the other hand.
The scheme of optimizing is that described graphite paper opposite side also is provided with single face glue.The other one side that promptly is provided with beyond the double faced adhesive tape at ground floor graphite paper 7 and second layer graphite paper 5 is pasted single face glue.The effect of single face glue is to wrap up graphite paper, avoids occurring the damaged problem of graphite paper.
Prioritization scheme further is that in the described single face glue, having one deck at least is insulation single face glue 4.As shown in Figure 2, the single face glue 8 on upper strata is thinner, for example adopts the film of 0.01mm thickness; The insulation single face glue 4 of lower floor is then thicker, for example adopts the film of 0.1mm thickness, and single face glue 8 is the one side near human body in the time of use; The one side that insulation single face glue 4 then is positioned at away from human body; Insulation single face glue 4 also has certain heat-insulating property except having the not damaged effect of protection graphite paper, can reduce heat waste to greatest extent like this.Prioritization scheme is that described single face glue is PET film single face glue.
