Abstract

The utility model discloses a high-efficient electric heat piece of no light, noiseless, no electromagnetic pollution with multiple use, its characterized in that's heating element is the enameled wire, and the enameled wire is A, B two, and the end of a thread of B are with a terminal of even power, and the end of a thread of B are with another terminal of even power. The electric heating sheet has simple structure and low cost, and the single sheet is suitable for low voltage use and the multiple sheets are connected in series and can be connected with the commercial power for use.

Description

By holding sheet

The utility model relates to a kind of electrothermal device, specifically a kind of electric heating piece.

Present electrothermal device has bulb, electric furnace and under blanket etc., and their common shortcomings are that specificity is strong, can produce light during use and disturb or magnetic disturbance.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and eliminates light and disturb, and removes the high-efficiency electric-heating sheet of electromagnetic pollution.

For achieving the above object, adopt following technical scheme:

Electric heating piece of the present utility model, it comprises heater element, parcel post and binding post, it is characterized in that described heater element is thin enamel covered wire, enamel covered wire is two of identical A, B, they are pressed close to and crooked with a gap folding is gone fixed in shape into any needs in parcel post, and A enamelled wire the end of a thread and B enamelled wire line tail are connected to become a contact, connect a power-line terminal, A enamelled wire line tail and B enamelled wire the end of a thread are connected to become another contact, another binding post of connecting with the mains.

Adopting technique scheme, is heater element with thin enamel covered wire, and the resistivity of copper is low, the heat generation rate of element unit length is few, can guarantee the low-temperature working state, thereby does not have the baking sensation, noiseless, light disturbs, and enamelled wire is thin, adopts connected mode of the present utility model again, and two enamelled wires flow through the reverse current of equivalent simultaneously, with these two enamelled wires of pressing close to is the axle center, magnetic field around it just stack offsets, and the magnetic effect of electric current is just overcome, and has eliminated electromagnetic pollution.Thereby the utility model is simple in structure, and design is unique, reaches to eliminate the light interference, removes the purpose of electromagnetic pollution.When light, the acoustomagnetic effect of electric current are all contained, according to power conversion and law of conservation, this moment electric energy to the transfer ratio of heat energy up to absolutely.

Fig. 1 is a structural representation of the present utility model;

Below in conjunction with accompanying drawing the utility model is further described:

Among the figure, the utility model electric heating piece has comprised heater element enamelled wire 1, parcel post 2 and two binding posts 3 in order to be connected with power supply, and wherein enamelled wire 1 is two of A, B, removes outside the surperficial coat of paint color difference, two enamelled wires are identical.Parcel post 2 can be abrasive paper, also can as fabric, reach fixedly enamelled wire 1 in order to parcel for other support that can conduct heat; Binding post 3 is thin binding post, in order to link to each other with two poles.

The utility model electric heating piece can be made like this: (1) two 0.13 millimeter enamel covered wires that color is different are pressed close to parallel, at long 0.7 meter, illustrate crooked folding to go by Fig. 1 on the wide 0.3 meter thin paper, there is outstanding nail point at the break place, nail point is detachable to fall, line and the gap of facing line are about 1 centimetre, and line folds to the end of a thread homonymy after coming and going 25 one way, and the end of a thread line tail is all reserved the end of a thread of 6 centimeter length; (2) lose terminal, brush Instant cement equably on line thin paper surface, cover another onesize thin paper, brush is put down, compresses, is backed off and follows closely point, gets the utility model electric heating piece base.(3) two the end of a thread of exchange color of the same race are in parallel with two the end of a thread of another root enamelled wire, scald coating removal skin, binding post in the last soldering with flatiron; (4) smear Instant cement on the position of fixing little binding post, ajust little binding post, cover little scraps of paper of smearing Instant cement again on binding post, compress, the link post just obtains the utility model electric heating piece.

The utility model electric heating piece is applicable to low pressure, according to top making data, is applicable to 12-15 volt voltage, can directly make free of contamination under blanket, is put under the sheet the 1 minute instant heating of switching on; Also can be used for fitting up between graceful unique electric greenhouse, be affixed on wall, cover decoration painting again, the multi-disc series connection inserts 220 volts of civil powers, and result of use is splendid simultaneously for the array stepping; Can also change the making parameter and make the honest heater element of hot-blast stove, cushion, vest and pin.

Claims

1. electric heating piece, comprise heater element, parcel post and binding post, it is characterized in that described heater element is an enamelled wire, enamelled wire is two of A, B, they are pressed close to a gap crooked folding and gos into the shape of any needs and be fixed in the parcel post, and A enamelled wire the end of a thread and B enamelled wire line tail be with a binding post that connects power supply, same another binding post that connects power supply of A enamelled wire line tail and B enamelled wire the end of a thread.

2. electric heating piece according to claim 1 is characterized in that described parcel post is a splicing tissue.
