Abstract

The utility model relates to a but pencil box of heat supply establishes the carbon fiber layer that generates heat in the pencil box upper cover, the pencil box bottom is built -in to have battery and a control chip, and the pencil box lateral wall sets up the USB interface that charges, the battery is the control chip power supply, and control chip control carbon fiber generates heat the layer and generates heat, and USB charges interface joinable power and charges, and whole structural design is simple reasonable, furthermore, the carbon fiber generates heat that high and to generate heat effect of thermal conductivity good for layer factor of safety, can make things convenient for safely be the pencil box heat supply effectively, but messenger's pencil box has played the function that the hand was warmed up in the heat supply well.

Description

A kind of pencil box that can heat supply

Technical field

The utility model relates to a kind of pencil box that can heat supply.

Background technology

Tradition pencil box is students in middle and primary schools' conventional stationery, and its enclosure material is mainly iron sheet or plastics, therefore always becomes ice-cold in cold case surface in winter, wants to open or close pencil box and all makes us extremely feeling bad; In addition, not heating in southern classroom, student does one's assignment while taking notes, palm is exposed to easily to catch a cold outward for a long time, and a lot of students just have to use hand warmer or hand are inserted in pocket, very inconvenient and impact study. Consider that pencil box is conventional stationery, student has attended class and has carried, if can allow as required pencil box generate heat safely and effectively, just can address the above problem.

Utility model content

The deficiency existing for prior art, the purpose of this utility model be to provide a kind of structural design advantages of simple, can safe and effective heat supply pencil box.

For achieving the above object, the utility model provides following technical scheme: a kind of pencil box that can heat supply, in pencil box upper cover, establish carbon fiber heating layer, pencil box bottom is built-in with battery and control chip, pencil box sidewall arranges USB charging inlet, described battery is control chip power supply, the heating of control chip control carbon fiber heating layer, and USB charging inlet can connect power source charges.

Further, at pencil box sidewall and bottom, carbon fiber heating layer is also set.

Further, described battery is electrically connected with control chip.

By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: as mentioned above design can heat supply pencil box, battery provides electric energy for control chip, control chip impels the heating of carbon fiber heating layer, carbon fiber heating layer is given the heat supply of whole pencil box shell by heat radiation, thereby play the function of driving changes in temperature hand, whole simplicity of design is reasonable; In addition, battery can be self-powered, when power shortage, connect power source charges by USB charging inlet, carbon fiber heating layer safety coefficient is high and heating and heat conducting is effective, can safe ready heat supply effectively, and control chip can switch and is regulated the heating of carbon fiber heating layer.

Fig. 1 is the overall structure schematic diagram of the utility model embodiment;

Fig. 2 is the design flow diagram of the utility model embodiment.

Description of reference numerals:

1. carbon fiber heating layer; 2. battery; 3. control chip; 4.USB charging inlet.

Detailed description of the invention

Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.

With reference to figure 1 and Fig. 2, what the invention process disclosed is a kind of pencil box that can heat supply, in pencil box upper cover, establish carbon fiber heating layer 1, pencil box bottom is built-in with battery 2 and control chip 3, described battery 2 is electrically connected with control chip 3, pencil box sidewall arranges USB charging inlet 4, described battery 2 is that control chip 3 is self-powered, when power shortage, can connect power source charges by USB charging inlet 4, control chip 3 can be controlled carbon fiber heating layer 1 and generate heat, and then gives the heat supply of whole pencil box shell by heat radiation, thereby plays the function of driving changes in temperature hand; Preferably, can carbon fiber heating layer 1 be also set at pencil box sidewall and bottom.

Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
