Abstract
An electrothermal pen consists of a battery installation position 1, a lead 2, a pen body 3, an electrothermal film 4, a refill 5, a temperature control switch 6 and an indicating lamp 7. The pen body is made of insulating heat-conducting materials, an antiskid wear resistant coating layer is arranged on the outer surface of the pen body, and a layer of electrothermal film is arranged on the inner side of the pen body. When batteries are installed in the electrothermal pen and the temperature control switch is turned on, the electrothermal film gives out heat, and the heat is conducted on the surface of the electrothermal pen uniformly through the pen body made of insulating heat-conducting materials. The electrothermal pen mainly solves the problem of inconvenience in writing in a low-temperature environment, and has the advantages of simple structure, convenience in carrying, safety in use, wide range of users and easiness in popularization.
Description
Technical field
A kind of heating plant under the present invention, particularly a kind of electrothermal pen.
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 a kind of electrothermal pen of hand while learn.
A kind of electrothermal pen of the present invention is characterized in that this electrothermal pen is handwriting with the insulating heat-conduction material, and the outer surface of handwriting has one deck anti-skid wearable coating, and the inboard of handwriting has one deck electric heating film.
The described wear-resistant coating of a kind of electrothermal pen of the present invention can be wear-resistant paints such as wear resistant resin.
The heat that when a kind of electrothermal pen of the present invention is worked the electric heating film energising is produced conducts the anti-skid wearable coating to the handwriting outer surface, 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 the structural representation of a kind of electrothermal pen of the present invention, and wherein 1 is the arranging batteries place, and 2 is lead, and 3 is handwriting, and 4 is electric heating film, and 5 is pen core, and 6 is the temperature control switch, and 7 is indicator lamp.
Fig. 2 is the expanded view at a kind of electrothermal pen Electric radiant Heating Film of the present invention and arranging batteries place, and wherein 1 is the arranging batteries place, and 2 is lead, and 4 is electric heating film.
The specific embodiment
A kind of electrothermal pen of the present invention is handwriting with the insulating heat-conduction material, and the outer surface of handwriting 3 has one deck anti-skid wearable coating, and the inboard of handwriting has one deck electric heating film.During use, place button cell in battery installation place 1, open the temperature control switch, owing to connect by lead, electric heating film 4 has electric current to flow through and generates heat, and heat energy is delivered to the surface equably by the insulating heat-conductive handwriting, makes temperature reach controllable temperature.
Claims (1)
1. an electrothermal pen has concurrently and writes and heating function, it is characterized in that: this electrothermal pen is handwriting with the insulating heat-conduction material, the outer surface of handwriting (3) has one deck anti-skid wearable coating, the inboard of handwriting has one deck electric heating film, and indicator lamp is arranged on the handwriting, can the indicating circuit duty.
