Abstract
The utility model relates to a heating pad which comprises a pad body 1, a temperature control switch and battery installation position 2, a metal blank body 3, an electric heating film 4 and wear-resistant coatings 5. Metal is taken as the blank body, the lower surface of the metal blank body is provided with a layer of electric heating film, and the lower surface of the electric heating film and the upper surface of the metal blank body are respectively provided with a layer of wear-resistant coating. When the heating pad is electrified, the electric heating film starts to heat, and heat is uniformly transferred on the surface of the heating pad through the metal blank body. The heating pad mainly solves the problem that people are inconvenient to write in the low-temperature environment, and after the heating pad is put below writing paper or paper material to be browsed, the human hand does not feel cold. The heating pad is characterized by simple structure, convenience in use, wide range of audience groups and easiness in popularization.
Description
Technical field
A kind of heating plant under the present invention, particularly a kind of heating backing plate.
Background technology
Known, along with the improvement day by day of people's living standard, people more and more pay attention to the study and work environment of self.But because country causes areas to the south, part the Changjiang river not have large-scale central heating place and systematized heat supply heating facility about the regulation of heating, winter temperature is still lower.A lot of workplaces especially in the university most of room for individual study temporarily popularize heat supply heating facilities such as air-conditioning, cause indoor temperature on the low side.Some classmate's association is with gloves, electric hot-water bag etc., writes but be not convenient for like this.
Summary of the invention
At the problem that exists in above-mentioned, the objective of the invention is to carry enough a kind of safe, good heat conduction effect, power consumption low, meet environmental protection standard and can allow people warm up the heating backing plate of hand while learn.
A kind of heating backing plate of the present invention is characterized in that this heating backing plate is base substrate with the metal, and the upper and lower surface of metal body has the heat-resisting mill coating of one deck, and the bottom surface of metal body has one deck electric heating film.
The described metal body of a kind of backing plate that generates heat of the present invention can be the metal material that thermal conductivity such as steel disc, aluminium flake are good and can slightly bend.
The described wear-resistant coating of a kind of heating backing plate of the present invention can be wear-resistant paints such as wear resistant resin.
The thermal source that the present invention is a kind of to be produced the electric heating film energising when generating heat backing plate work conducts the refractory coating of refractory coating to the metal body lower surface, metal body, metal body upper surface successively, has the advantages that heat conduction is even, heat transfer efficiency is high, power consumption is low.
In sum, the present invention has that heat conduction is even, heat transfer efficiency is high, power consumption is low, safe in utilization, the advantage that is easy to carry and is convenient to use under the low temperature.
Description of drawings
The present invention is described further below in conjunction with embodiment.
Fig. 1 is a structural representation of the present invention, and wherein 1 is the backing plate main part, and 2 is temperature control switch and battery installation place.
Fig. 2 is a structure cutaway view of the present invention, and wherein 3 is metal body, and 4 is electric heating film, and 5 is wear-resistant coating.
The specific embodiment
The present invention's backing plate that generates heat is base substrate with the metal, and the upper and lower surface of metal body 3 has one deck wear-resistant coating 5, between metal body 3 and lower surface wear-resistant coating one deck electric heating film 4 is arranged.
During use, place battery in battery installation place 2, open the temperature control switch, electric heating film 4 has electric current to pass through to generate heat, and heat energy is delivered to the backing plate surface more equably by metal body, makes temperature reach controllable temperature.
Claims (1)
