Abstract

The invention discloses a graphite heat conductor-based electric blanket, which comprises an electric blanket; a heating cable is arranged in the electric blanket; and two pieces of graphite paper are arranged at two sides of the heating cable. A double-sided adhesive tape is arranged between the two pieces of graphite paper. The graphite heat conductor-based electric blanket is provided with the graphite heat conductors, so that the problems of energy waste and potential safety hazard of the traditional radiating fin are solved; because the graphite has extremely strong heat conductivity (which can even exceed the heat conductivities of copper and aluminum after treatment), the graphite heat conductor can transfer the heat to a position beyond 100 millimeters in short time (within about 5 seconds) when the heating cable generates heat, the interval of the internal heating cable can reach over 150 millimeters and the heating effect is not affected; and in addition, because the heat can be quickly dissipated by the graphite heat conductors, namely the graphite paper, heat is not accumulated nearby the heating cable, and risks are avoided.

Description

Electric blanket based on the graphite heat conducting body

Technical field

The present invention 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, and the heat build-up phenomenon of traditional electric blanket has been wasted electric energy greatly, shows that mainly that heating cable need be arranged is very close in order to reach uniform heating; 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

Technical problem to be solved by this invention provides a kind of electric blanket based on the graphite heat conducting body, and the heat that heating can be produced transmits rapidly to be opened, and eliminates safe hidden trouble.

For solving the problems of the technologies described above, the technical solution adopted in the present invention 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.

The other one side that described graphite paper is provided with beyond the double faced adhesive tape 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 based on the graphite heat conducting body provided by the invention, by 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 heating cable of inside of the present invention can reach at interval 150mm, this distance is more than three times, according to heating power formula P=I of existing electric blanket internal heat generation cable interval 2R and resistance formula R=σ L/S as can be known, electrical power P is directly proportional with the resistance wire length L, that is to say the present invention in theory power consumption can be reduced to 1/3rd of electric blanket power consumption of the prior art, so the present invention has energy-efficient advantage; In addition, can rapidly heat be scattered because the graphite heat conducting body is graphite paper among the present invention, therefore the phenomenon of heat build-up near heating cable, can not occur, thereby avoid the generation of unsafe condition.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples:

Fig. 1 is structural representation of the present invention.

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, by graphite paper conduction heat, two-layer graphite paper is key of the present invention up and down, after heating cable 2 heating 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 among the present invention is when adopting as the arrangement mode among Fig. 1, can adopt wideer spacing B, the spacing of 150mm for example, can reach and the identical heating effect of prior art 45mm spacing, therefore also save raw material, owing to shortened the length of heating cable 2, also saved electric energy.

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, is that ground floor graphite paper 7 and second layer graphite paper 5 are combined on the one hand, 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.Namely be provided with double faced adhesive tape other one side stickup single face glue in addition at ground floor graphite paper 7 and second layer graphite paper 5.The effect of single face glue is to wrap up graphite paper, avoids occurring the problem of graphite paper breakage.

Further prioritization scheme is, 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 adopt 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.
