Abstract
The utility model discloses a cap of a pen generates heat, which comprises a sleeve, the sleeve is sandwich structure, is equipped with spontaneous heating powder in the intermediate layer, and the sleeve is equipped with the sliding sleeve outward, be equipped with each other matched with bleeder vent on sliding sleeve and the telescopic intermediate layer outer wall. The utility model discloses both having can be used to the heating, and can also being used for melting the ink that the pen nib solidifies, it has characteristics such as low in production cost, simple structure, convenient to use.
Description
Technical field
The utility model relates to the cap of a pen, especially a kind of heating cap of a pen.
Background technology
In the winter of cold, student is outside when writing, hand is chronically exposed to, easily cause frostbite, if put on thermal glove can cause dysgraphia again, therefore people add that on pen electro-heat equipment is for heating, modal is at present electrical heating and solar energy heating, but electrically heated structure is very complicated, production cost is very high, and particularly temperature is not easy to control, the efficiency of solar energy heating is too low, and indoor temperature is often not easy to reach.
In addition, at very low temperature, the ink of Pen nib easily solidifies and cannot write.
Spontaneous heating powder is that one in atmosphere oxidation reaction can occur, and the material of release heat, be add iron powder based on powdered carbon mostly, its heating principle is under the effect of powdered carbon, iron powder and air contact surfaces are long-pending to be increased, by with oxygen generation oxidation reaction and release heat.The feature of spontaneous heating powder is that electrothermal calefactive rate is fast, and temperature ratio is easier to control.
Summary of the invention
The purpose of this utility model is to provide a kind of heating cap of a pen, and this cap of a pen for thermal source, not only can be used for heating with spontaneous heating powder, can also be used for melting the ink that pen nib solidifies.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of heating cap of a pen, comprise sleeve, described sleeve is sandwich, is provided with spontaneous heating powder, is provided with sliding sleeve outside sleeve in interlayer, and the interlayer outer wall of described sliding sleeve and sleeve is provided with the air-vent of working in coordination.
The interlayer outer wall of described sliding sleeve and sleeve is respectively provided with several rows air-vent, and the aperture of air-vent is 0.5 ~ 2mm, and the air-vent on sliding sleeve and sleeve interlayer outer wall at least can a line overlap, and can all overlap at most.
Described sliding sleeve is provided with fountain pen clip.
The utility model adopts spontaneous heating powder to replace conventional electrical heating, and the temperature of heating is more controlled, and volume is less, and carry convenient, price is cheaper.Spontaneous heating powder needs could generate heat under the condition of aerobic, by establishing air-vent on sleeve and sliding sleeve, and closedown or the opening of air-vent is regulated by rotating sliding sleeve, when air-vent is closed completely, spontaneous heating powder in interlayer can not ingress of air and can not generating heat, can long time stored, transport, when air-vent is opened, enter air in interlayer, spontaneous heating powder starts persistent fever.The quantity that air-vent is opened can be regulated by sliding sleeve, and it is more that air-vent is opened, and the air entered in interlayer is more, and the temperature of spontaneous heating powder is higher, otherwise then less.The features such as the utility model both can be used for heating, and can also be used for melting the ink that pen nib solidifies, it is low that it has production cost, and structure is simple, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
Embodiment: as shown in Figure 1, 2, a kind of heating cap of a pen, comprise sleeve 1, described sleeve 1 is sandwich, is provided with spontaneous heating powder 2, is provided with sliding sleeve 3 outside sleeve 1 in interlayer, and the interlayer outer wall of described sliding sleeve 3 and sleeve 1 is provided with the air-vent 4 of working in coordination.The interlayer outer wall of described sliding sleeve 3 and sleeve 1 is respectively provided with several rows air-vent 4, and the aperture of air-vent 4 is 1mm, and the air-vent 24 on the interlayer outer wall of sliding sleeve 3 and sleeve 1 at least can a line overlap, and can all overlap at most.Described sliding sleeve 3 is provided with fountain pen clip 5.
Described spontaneous heating powder 2 is become to be grouped into by iron powder, carbon dust, vermiculite, resin, salt etc., and particle diameter is greater than 5mm, and obtain by commercial sources, its maximum heating temp is 80 DEG C, and minimum heating temp is 50 DEG C.
