Abstract

The utility model relates to a pen cap comprising a cap body and a battery, wherein the cap body is a semiconductor chilling plate, the heat radiating end of the semiconductor chilling plate is located on the inner ring surface of the cap body, the chilling end of the semiconductor chilling plate is located on the outer ring surface of the cap body, and the semiconductor chilling plate is connected with the battery through a circuit. The utility model also relates to a pen comprising a penholder and the pen cap. The heat is released on the inner ring surface of the cap body according to the working principle of the semiconductor chilling plate, so that the penholder inserted into the pen cap is heated to avoid the condition that the writing of a user is influenced in frigid weather.

Description

A kind of pen cap and pen

Technical field

The utility model relates to a kind of pen cap and pen.

Background technology

Write and be seen everywhere in daily life, but under special environment, can affect the effect of writing owing to being subject to the impact of environment, main manifestations in the following areas:

1, winter, our the south of the lower reaches of the Yangtze River weather is colder, and in the situation that not warming oneself condition, writing time has been grown hand can become stiff, is inconvenient to write;

2, under dim environment, also can affect the sight line of writing, writing effect is exerted an influence.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of pen cap and pen are provided, can heat the penholder being inserted in the pen cap, conveniently write, and can overcome by the lighting pilot lamp on penholder the defect that under dim environment, impact is write.

The utility model solves the technical scheme that its technical problem adopts: a kind of pen cap, comprise body and battery, described body is semiconductor chilling plate, the radiating end of described semiconductor chilling plate is positioned at the inner ring face of body, the refrigeration end of semiconductor chilling plate is positioned at the outer ring face of body, and described semiconductor chilling plate forms circuit with battery and is connected.

Further, on described body, be provided with supporting rod, described battery is arranged on supporting rod, is also provided with lighting pilot lamp and for controlling the first switch of lighting pilot lamp work on supporting rod.

Further, on the circuit between described semiconductor chilling plate and battery, be provided with the second switch that is communicated with or disconnects for control circuit.

A kind of pen, comprises penholder and the pen cap, and the described pen cap adopts the above-mentioned pen cap.

The beneficial effects of the utility model are: utilize the operation principle of semiconductor chilling plate, in the inner ring face release heat of body, thereby make to be inserted in heat on the penholder band in the pen cap, thereby avoid affecting user at cold snap, write.

By being arranged on the lighting pilot lamp on supporting rod, facilitate user to write in the place that the light is dusky.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 be the pen cap partly cut open structural representation;

Fig. 2 is the stereogram of the pen cap;

Fig. 3 is the structural representation of pen.

Wherein: 1, body, 2, supporting rod, 3, battery, the 4, first switch, 5, lighting pilot lamp, 6, penholder.

The specific embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

As shown in Fig. 1 Fig. 2, a kind of pen cap, comprises body 1 and battery 3, body 1 is semiconductor chilling plate, the radiating end of semiconductor chilling plate is positioned at the inner ring face of body 1, and the refrigeration end of semiconductor chilling plate is positioned at the outer ring face of body 1, and semiconductor chilling plate forms circuit with battery 3 and is connected.Utilize the operation principle of semiconductor chilling plate, in the inner ring face release heat of body 1, thereby the penholder 6 that makes to be inserted in the pen cap is with heat, thereby avoid affecting user at cold snap, writes.

On body 1, be provided with supporting rod 2, battery 3 is arranged on supporting rod 2, the first switch 4 that is also provided with lighting pilot lamp 5 on supporting rod 2 and works for controlling lighting pilot lamp 5.The first switch 4 is controlled the work of lighting pilot lamp 5, facilitates user to write in the place that the light is dusky.

On circuit between semiconductor chilling plate and battery 3, be provided with the second switch that is communicated with or disconnects for control circuit.By second switch, just can control the work of semiconductor chilling plate, in the time of often need to be with pen, second switch can be opened for a long time, if need not second switch can be closed by pen for a long time, just can play like this effect of power saving.

Semiconductor chilling plate, is also thermoelectric module, is a kind of heat pump.It is comprised of two potsherds, has the semi-conducting material (bismuth telluride) of N-type and P type in the middle of it, and this semiconductor element is to link and form by series connection form on circuit.When a N-type semiconductor material and P-type semiconductor material be coupled to galvanic couple to time, in this circuit, connect after DC current, the just energy-producing transfer of energy, the joint absorption heat that electric current flows to P type element by N-type element becomes cold junction, and the joint release heat that electric current flows to N-type element by P type element becomes hot junction.

The work running of semiconductor chilling plate is that it not only can freeze but also can heat with DC current, by changing the polarity of DC current, decides realization refrigeration or heating on same cooling piece, and heating efficiency is very high, is forever greater than 1.The temperature range of semiconductor chilling plate, can realize to 130 ℃ of negative temperatures from 90 ℃ of positive temperature.

As shown in Figure 3, a kind of pen, comprises penholder 6 and the pen cap, and the pen cap adopts the above-mentioned pen cap, and penholder 6 is inserted in necessary inner chamber, can under the effect of semiconductor chilling plate radiating end, to penholder 6, heat, and facilitates user to use in arctic weather.

The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
