Abstract

The utility model discloses an electric blanket which comprises an electric heating layer and a wrapping layer, wherein a plurality of carbon fibers are woven inside a cloth body on the electric heating layer, the electric heating layer is combined with a power cord which is riveted with each carbon fiber by rivets; the wrapping layer is wrapped outside the electric heating layer, when a DC power supply of 10V to 20V is electrified to the power cord, the carbon fibers generate quantity of heat and does not generate electromagnetic waves. The electric blanket can be used for manufacturing products such as clothes, loincloth and corset, and has the function of maintaining human health.

Description

Electric blanket

Technical field

The utility model relates to a kind of electric blanket, relates in particular to a kind of electric blanket with many carbon fibres with distribute heat.

Background technology

Electric blanket is often to be used for warming clothing or bed clothes cold season, its structure mainly is to bury the metal electric heating silk with thermal conductive property in woollen blanket underground, yet the employed heating wire of traditional electric blanket can produce the electromagnetic wave of higher-strength when energising, so that can be to user's healthy generation harmful effect.And electric blanket can absorb human body or airborne moisture after using a period of time unavoidably, and moisture influences this heating wire easily and cause short circuit, even if water is dialled when spilling to electric blanket accidentally, the easier thereby danger that causes electric leakage and get an electric shock.In addition, the heating wire of traditional electric blanket is to adopt the copper product manufacturing mostly, and is light inadequately during use so whole electric blanket weight is heavier, and its comfort level is also not enough.

The utility model content

Main purpose of the present utility model is to solve existing electric blanket and the time can produces the high-strength magnetic ripple and be unfavorable for health, be subjected to moisture and moisture effects easily and cause short circuit or problems such as electric shock, the heavier and inconvenient use of overall weight in energising.

In order to achieve the above object, the utility model provides a kind of electric blanket, includes:

One electrothermal layer has a cloth body, is woven with many carbon fibres in this cloth body, and is combined with power line at this electrothermal layer, and this power line and each described carbon fibre are connected in parallel;

One clad be coated on this electrothermal layer outside, and described power line passes this clad.

Described each bar carbon fibre is woven into " M " shape.

Described power line is fixed in this carbon fibre with the rivet that possesses conduction property and electrically connects.

The beneficial effects of the utility model are that employing has the carbon fibre of thermal conductive property to be imbedded in the cloth body, and the carbon fibre is connected with power line, makes when power line is passed into electric current, produced heat by to be allowed the carbon fibre.By this characteristic of carbon fibre material as nonmetallic materials and light weight, make it be passed into the electric current adstante febre and can not generate electromagnetic waves, can not be subjected to moisture and moisture effects and leak electricity or get an electric shock, and product such as electric blanket of making, clothes, band, corset is lighter, comfortable.

Fig. 1 is for showing the stereogram of electric blanket among the utility model embodiment.

Fig. 2 is for showing the plan view of electric blanket among the utility model embodiment.

Fig. 3 utilizes rivet with the fixing partial schematic diagram of power line and the fine end of carbon for showing among the utility model embodiment.

The specific embodiment

Below cooperate and graphic embodiment of the present utility model is done more detailed description, any those of ordinary skill in the art can be implemented according to this studying the present specification postscript carefully.

As shown in Figures 1 and 2, the electric blanket that the utility model provides includes an electrothermal layer 1 and a clad 2, and this electrothermal layer 1 is coated on this clad 2 inside.Described electrothermal layer 1 has the made cloth body 11 of material by any suitable manufacturing bed clothes such as cotton, hair, nylon, and when making this cloth body 11, in this cloth body 11, be woven with the carbon fibre 12 of many nonmetallic materials, make carbon fibre 12 become the part of cloth body 11 structures.In preferred embodiment of the present utility model, described each bar carbon fibre 12 is woven to " M " shape (as shown in Figure 2).One side of electrothermal layer 1 then is combined with an anode supply line 3 and a cathode power line 4, first end 121 of this M shape carbon fibre 12 is connected with power line 3, second end 122 then is connected with cathode power line 4, this anode supply line 3 passes cloth body 11 with 4 of cathode powers and is connected power supply outward, makes described carbon fine 12 form parallel circuits.The preferable connected mode of described carbon fine 2 and power line is to adopt the rivet 5 that possesses conduction property that anode supply line 3 or cathode power line pressure are pulled as illustrated in fig. 3 and be fixed in cloth body 1 together.

Described clad 2 is used for coating the surfacing of this electrothermal layer 1, and its similar general quilt cover after clad 2 envelopes electrothermal layer 1, also makes this power line 3 pass this clad 2.

By aforementioned structure of the present utility model, described anode supply line 3 can be connected to a transformer (not shown) with cathode power line 4, this transformer then connects a plug, when inserting supply socket by plug, alternating current is converted to direct current and is imported fine 12 heatings of carbon by transformer; Described carbon fibre 12 also can be connected to the battery chamber, provides dc source by battery.Better embodiment of the present utility model feeds this power line with the direct current of 10V～20V, can make that described carbon is fine to produce heat, and can not generate electromagnetic waves, and can not be subjected to moisture and moisture effects and leak electricity or get an electric shock, and the electric blanket of making is lighter, comfortable.

The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; therefore; all have in that identical utility model spirit is following do relevant any modification of the present utility model or change, all must be included in the category of the utility model intention protection.
