Abstract

The invention discloses a pen with the heat preservation function and the heating function. The pen comprises a pen head with a pen point, a pen barrel connected with the pen head, and a pen bag connected to the pen head, wherein the pen bag arranged on the pen head extends into the pen barrel, and the pen head is connected with the lower end of the pen barrel through threads. The pen is characterized in that a pen bag installing cavity, a vacuum heat insulation cavity and a heating cavity are formed in the pen barrel from inside to outside, the heating cavity is filled with heat-conducting media, a heating driving module is embedded into the upper end of the pen barrel, a heating wire connected to the heating driving module extends into the heating cavity, and the power supply end of the heating driving module is connected with a USB interface through a wire. The pen has the remarkable advantages that a pen body is simple in structure; when the pen is used, electricity is provided through the USB interface, and the power supply cost is reduced; due to cooperation between the heating cavity and the vacuum heat insulation cavity, heating of the pen body is ensured, the pen bag of the pen can be prevented from being burnt, and a user can conveniently use the pen in cold winter.

Description

A kind of pen with warming heating function

Technical field

The present invention relates to a kind of pen, specifically, is a kind of pen with warming heating function.

Background technology

Although the arriving of electronic age has replaced many things, pen also still exists in many application scenarios, and particularly finance are done account, leader's signature etc., also cannot depart from completely the hand-written epoch.

Pen is as a kind of routine office work and study article, and except realizing simple writing function, its performance requirement of people is also more and more higher.

Particularly, in cold winter, finance are done account need to grip pen writing for a long time, and hand is easily freezing, although be with the gloves can be warming, writes and inconvenient, if pen self can generate heat, so just can avoid above problem.

By patent retrieval, find, a tool that has existed some to have heat-preserving function in prior art, analyzes and finds, is mainly designed with following several:

(1) by injecting warm water, realize heat-preserving function, the pen container that is equivalent to pen is a warm water storage chamber, promotes the temperature of a body by closing hot-water flooding, realizes heat-preserving function.But while using, the warm water chamber on pen container is excessive, must increase the volume of handwriting, grip inconvenience, if pen container is too small, perfusion warm water has difficulties, and temperature continuation is not strong.

(2), by heater strip being set at pen with it, utilize heater strip to generate heat to realize heat-preserving function.But large multi-scheme adopts powered battery, and cost is higher, if adopt DC power supply, likely exist the too high capsule that causes of heating to scorch.

Summary of the invention

In view of the defect that prior art exists, the present invention proposes a kind of pen with warming heating function, when realizing a body heating function, can avoid again excess Temperature to cause a capsule to scorch, and solves powerup issue simultaneously, reduces operating cost.

For achieving the above object, concrete technical scheme of the present invention is as follows:

A kind of pen with warming heating function, comprise the nib with nib, the pen container being connected with nib and be connected to the capsule in nib, wherein, a capsule in described nib stretches in pen container, nib is threaded connection with the lower end of pen container, its key is: on described pen container by being provided with successively a capsule installation cavity outside interior, vacuum heat-insulation chamber and heating chamber, in described heating chamber, be filled with heat-conducting medium, in the upper end of described pen container, be embedded with heat driven module, the heater strip connecting in this heat driven module stretches in described heating chamber, feeder ear in this heat driven module is connected with USB interface by wire.

By above-mentioned design, USB interface is plugged on the equipment such as computer, charger or portable power source, heat driven module can drive electrothermal wire heating, after the heating of heat-conducting medium in heating chamber, can conduct on the outer wall of pen container, with hand, grip while writing, can guarantee certain temperature, prevent that winter is outside exposed by hand and the frostbite that causes utilizes vacuum heat-insulation chamber by a capsule and heating chamber isolation simultaneously for a long time, avoids because heating wire excess Temperature causes the damage of a capsule.

As further describing, the chamber wall in described vacuum heat-insulation chamber is made by the heat-barrier material that insulate.

Further describe, described insulating heat-conduction material is heat-conducting plastic again, and described insulation heat-barrier material is pottery.

For the ease of fixing of heater strip, the heater strip in described heating chamber is wound on the chamber wall of heating chamber.

Remarkable result of the present invention is: handwriting is simple in structure, during use, by USB interface, powers, and reduces power supply cost, by the cooperation in heating chamber and vacuum heat-insulation chamber, when guaranteeing a body heating, can avoid again fountain pen ink cartridge to be ruined, very easy to use in cold winter.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

As shown in Figure 1, a kind of pen with warming heating function, comprise the nib 1 with nib, with nib 1 pen container being connected 2 and be connected to the capsule 3 of nib on 1, wherein, described written 1 is threaded in the lower end of pen container 2, a capsule 3 in nib 1 stretches in pen container 2, on described pen container 2 by being provided with successively a capsule installation cavity 4 outside interior, vacuum heat-insulation chamber 5 and heating chamber 6, in described heating chamber 6, be filled with heat-conducting medium, in the upper end of described pen container 2, be embedded with heat driven module 7, the heater strip connecting in this heat driven module 7 stretches in described heating chamber 6, feeder ear in this heat driven module 7 is connected with USB interface by wire 8.

In specific implementation process, the outer wall of pen container 2 is made by insulating heat-conduction material, can be heat-conducting plastic, can be also the metal-back that is coated with insulated paint, and the chamber wall in described vacuum heat-insulation chamber 5 is made by the heat-barrier material that insulate, can Ceramics.Heat driven module 7 is actual is a power transfer module, for realizing the conversion of USB power supply, according to user's demand, USB interface can be plugged on notebook, portable power source or the power supply adaptor with USB power supply interface, for finance, handle official business especially, very convenient, because they should do account by electronics, the hand-written account of doing again.

In implementation process, heater strip in described heating chamber 6 can draw in the heat-conducting medium of heating chamber 6, also can be wound on the chamber wall of heating chamber 6, and the heat-conducting medium that heating chamber 6 is filled can be water, also can select the fluent material of other high thermal conductivities, guarantee that heat radiation evenly.

By using the warming pen of this programme design, when heat-preserving function is provided, the defect that has caused a capsule to scorch while having avoided again heating, and also power supply is convenient, with low cost.

Finally it should be noted that, although be described with reference to embodiments of the invention here, but should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.
