Background technology
Along with the lifting of standard of living, various heating or warm keeping element or product arise at the historic moment, and are widely used on the product miscellaneous, as be located in the country in frigid zone, winter temperature is extremely low to cause the automobile rearview mirror frosting, often needs to cause the inconvenience in the driving with its surface of manual wipping; Perhaps, because of the weather temperature is low, and the heat insulation effect of blanket is restricted.
For solving the above problems, therefore heating elements such as installing electric heating piece at the automobile rearview mirror back side additional is arranged with defrosting, or in blanket, bury heating element underground to promote heat insulation effect.Its heating element then such as No. the 474547th, the novel patent of China bulletin the announcement electric heating piece, its again a soft board be longitudinally set with interlaced positive and negative electric lead more than two, be horizontally set with thermal wire more than two again forming the mesh shape, and make electric lead and thermal wire connection in series-parallel to be divided into several heating regions.Heating is with the effect of defrosting or insulation though its electric heating piece can heat up, precisely because electric heating piece mainly is to be printed on soft board to form positive and negative electric lead with electrically conductive ink, and printing conductive carbon forms thermal wire, its heat conduction only is thermal conductive wire, slow or the temperature maintenance of the programming rate of temperature is restricted, and can't reach the heating or the heat preservation effect of expection, and its electric lead is to form with electrically conductive ink printing, oven dry, manufactures loaded down with trivial details disadvantages such as time-consuming.
The inventor is because every shortcoming that above-mentioned existing electric heating piece and manufacture method thereof are derived, be urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, finally successfully research and development to finish a kind of be the conductive film of fitting on base material, again in conductive film printing two mutually staggered conducting wires, and are the electric heating pieces that are riveted on described conducting wire respectively with two conducting strips, it must printing conductive carbon, be convenient to manufacture, more can heat up rapidly, and can effectively keep temperature and reach purpose of energy saving.
Summary of the invention
Main purpose of the present invention, be to be that electric conducting material is a whole piece formula conductive film, and can directly be attached on workpiece or the flexible substrate, and must printing conductive carbon, simple structure, be convenient to manufacture, and the full slice system conductive film can heat up rapidly, and can effectively keep temperature and reach purpose of energy saving.
Another object of the present invention, be base material and conductive film can be selected from the tool reelability PET, PC or base materials such as PP film or cloth, and can coat or be fitted in the product of different size, material or moulding in response to client's various demands.
A further object of the present invention is the electric conducting material that is to make the apparatus positive temperature coefficient, because the expansion of material itself will make that resistance value relatively improves, therefore the magnitude of current of input also will reduce, and reach constant temperature and purpose of energy saving in temperature-rise period.
For achieving the above object, the technical solution used in the present invention comprises:
A kind of electric heating piece is characterized in that, comprising:
One base material;
One conductive film is fitted in described base material one side;
At least two conducting wires are printed on the one side of described conductive film;
At least two conducting strips are riveted on respectively on the conductive film and base material of the end points of described two conducting wires and bottom surface thereof.
For achieving the above object, the technical solution used in the present invention is also drawn together:
A kind of manufacture method of electric heating piece is characterized in that, its step is as follows:
At the base material conductive film of simultaneously fitting;
At described conductive film surface printing electrically conductive ink, and oven dry is to form at least two conducting wires;
Described two conducting strips are riveted on respectively on the conductive film and base material of the end points of described conducting wire and bottom surface thereof.
Compared with prior art, the beneficial effect that the present invention has is: the manufacture method that relies on the made electric heating piece of above-mentioned steps, it is to be the base material conductive film with positive temperature coefficient of simultaneously fitting, again in conductive film printing two mutually staggered conducting wires, and are the electric heating piece persons that are riveted on described conducting wire, conductive film and base material respectively with two conducting strips, its electric conducting material is a whole piece formula conductive film, and can directly be attached on workpiece or the flexible substrate, republish the conducting wire thereon, and must printing conductive carbon, can be convenient to manufacture.
