The utility model relates to a nonmetallic electro-thermal fiber warm vest, which comprises a vest. The front and the back of the vest are provided with a front electric heating sheet and a back electric heating sheet; a battery is arranged on the vest, and the battery, the front electric heating sheet and the back electric heating sheet form a series circuit; and electrodes are connected into the series circuit and then are placed on the vest. The nonmetallic electro-thermal fiber warm vest is characterized in that the electric heating sheet comprises a conductive film sheet, a carbon nano fiber coat is manufactured on the conductive film sheet, and insulating material layers are wrapped outside the conductive film sheet and the carbon nano fiber coat. The nonmetallic electro-thermal fiber warm vest has the advantages of long service life and safety, good heating and warming performance, convenient manufacture, firmness and durability, safety and reliability, and lower processing cost.
Description
Technical field
The utility model relates to a kind of non-metal electric heating fiber Thermal insulating vest, belongs to electrothermal vest technical field.
Background technology
At present, the electrothermal clothes of supplying on the market, products such as electric blanket, the plain conductor that is coated with paint film or plastic layer outside general the employing is made thermo electric material, make in clothes or woollen blanket, the voltage of external power supply is commonly 220 volts, and the resistance of plain conductor is more than 300 ohm, about 0.5 ampere in electric current, make the plain conductor heat release and heat through energising.Civilian electrothermal clothes, electric blanket use through long-term, bend by pressure cause film aging broken, even the plain conductor short circuit that fractures, product is easily aging and use dangerous, be 220 volts of voltages because of additional power source simultaneously, cause the human injury easily, during use certain precautionary measures must be arranged.
In addition, also supply with the carbon fiber on the market is the electric heating dress ornament and the electric blanket of heating material, the outside naked of carbon fiber electrothermal line wherein, only processing during electric heating piece with manually taking insulation processing, technology is unreasonable, and processing is also inconvenient, and the electric heating carbon fiber strength is not enough, can not fully satisfy the making requirement of electric heating clothes, certain limitation is arranged.
Summary of the invention
The purpose of this utility model provides the non-metal electric heating fiber Thermal insulating vest of a kind of long service life and safety.
In order to achieve the above object, the technical solution of the utility model has provided a kind of non-metal electric heating fiber Thermal insulating vest, comprise vest, electric heating piece and back electric heating piece before on the front of vest and back, being respectively equipped with, battery is located on the vest and with preceding electric heating piece and back electric heating piece and is formed series loop, electrode inserts series loop and is placed on the vest, it is characterized in that, electric heating piece comprises conductive film sheet, on the conductive film sheet, be manufactured with the carbon nano-fiber coating, be wrapped with insulation material layer in conductive film sheet and carbon nano-fiber coating.
Further, the area of described preceding electric heating piece is 80mm * 160mm～120mm * 200mm.
The area of described back electric heating piece is 130mm * 370mm～170mm * 370mm.
The utility model substitutes original plain conductor or carbon fiber with the carbon nano-fiber coating, and the teflon insulation film is arranged as wrapped with insulation.The carbon nano-fiber coating makes electric heating piece of the present utility model prolong greatly service life, and compression strength height simultaneously is again because the proportion of carbon nano-fiber is about 1.58 similar with cotton fiber, in light weight; Carbon nano-fiber itself possesses heat insulation and heat-insulating property, and self-characteristic has determined that again it is a kind of good fire-retardant, anticorrosive, can also antistatic, be suitable for dressing as dress ornament.Teflon insulation is film-insulated effective, and is fire-retardant, and anticorrosion is antistatic, and is safe and reliable.
The utility model has the advantages that: long service life and safety, the heating warm-keeping performance is good, easy to make simultaneously, firm and durable, safe and reliable, processing cost is lower.

The front view of a kind of non-metal electric heating fiber Thermal insulating vest that Fig. 1 provides for the utility model;
The rearview of a kind of non-metal electric heating fiber Thermal insulating vest that Fig. 2 provides for the utility model;
Fig. 3 is the structured flowchart of electric heating piece.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, the schematic diagram of the non-metal electric heating fiber Thermal insulating vest that provides for the utility model is made up of vest 1, preceding electric heating piece 2, back electric heating piece 3.
Preceding electric heating piece 2 and back electric heating piece 3 manufacturing process are for to be produced on carbon nano-fiber coating 7 on the conductive film sheet 6, at conductive film sheet 6 and carbon nano-fiber coating 7 outer wrapping polytetrafluoroethylene films 8.Single fiber irregular alignment in the carbon nano-fiber coating, single fiber resistance are 5 * 10
-4Ohm * 100nm.The heating of electric heating piece integral body and conduction are that the summation of the electrocaloric effect of every fiber constitutes.The resistance of electric heating piece is subjected to influencing jointly of resistance sizes between single fiber, but mainly based on the resistance of single fiber, so all-in resistance R
AlwaysCan be used as the result in parallel of n root single fiber Ri, as shown in the formula:
1/R
Always=1/R1+1/R2++ ... + 1/Rn=∑ 1/Ri
So under external voltage V, power can calculate with Ohm's law: W=V
2/ R
AlwaysCaloric value available electrical power formula is roughly estimated: Q=0.24IVt.Present embodiment is selected R
AlwaysBe 40 ohm, voltage is 8 volts, and power is 36 watts.Relation between the branch electric current I i of each individual carbon fibers of total current I summation is as shown in the formula I
Always=I1+I2+ ... so+In=∑ Ii is total current I
AlwaysAt 0.5～1 ampere-hour, the current value of single fiber is extremely weak.
Connect power supply after 2～3 minutes, heating sheet surface temperature reaches 25～35 degree, has worn next to the skin cosy sensation.
