Abstract

A heating pen comprises a power supply switch, a power supply, a PTC front end, a PTC rear end, a PTC, a metal contact, heat conducting materials, an upper pen body, a lower pen body and a pen point. The heating pen is characterized in that the power supply is fixedly arranged inside the top end of the upper pen body; the power supply switch is arranged at the top end of the upper pen body; two electrodes of the power supply are connected with two front ends of a heating device PTC; two rear ends of the heating device PTC are fixed onto the metal contact on the upper pen body; the metal contact is used for leading the heating device to be more closely connected with the pen bodies, so that heat of the heating device can be sufficiently used by the pen bodies, and the heat conducting materials are evenly adhered onto the rest portions inside the upper pen body, thereby the heating pen achieves the purposes of capabilities of evenly dissipating heat and keeping constant temperature, safety and convenience. The heating pen overcomes the shortcoming that a user can not write good calligraphy because fingers of the user are frozen and stiff when writing with a pen in winter, and the heating pen has the advantages of simple structure, safe and convenient use, and easy production and popularization.

Description

A kind of heat pen that adds

Affiliated technical field

The utility model relates to the cultural tools field, particularly a kind of technical field of the pen that generates heat.

Background technology

At present, there is safety problem in known heating pen in practice, and can not be adjusted to constant temperature automatically along with the variation of ambient temperature, and its practicality is restricted.Start writing winter and usually can't finish writing word when writing, also do not find a kind of pen of heated at constant temperature persistent fever at present because finger is numb with cold.

Summary of the invention

The purpose of this utility model is to provide simple in structure, safe and convenient to use in order to overcome the deficiencies in the prior art, can effectively prevent to point numb with cold and can make finger keep a kind of heat pen that adds of constant temperature when writing.

The technical solution of the utility model is: by power switch, power supply, PTC front end, PTC rear end, PTC, hard contact, Heat Conduction Material, form on one's body by body, a body lower body, nib for pen.The pen top internal fixation of body on one's body is provided with power supply, the switch of power supply is arranged on the pen top of body on one's body, two poles connects the two ends, front of electro-heat equipment PTC by wire, two ends, electro-heat equipment PTC back are fixed on the pen pen hard contact of body on one's body, hard contact is in order to make heater be connected tightr with a body, the heat of heater is made full use of by a body, Heat Conduction Material on the inner remainder of body on one's body the pen is evenly bonding, be able to Homogeneouslly-radiating, can keep the purpose of constant temperature and safe ready.

The beneficial effects of the utility model are: it is numb with cold and can't finish writing the shortcoming of word to have solved the finger when writing of starting writing winter, and the design is simple in structure, safe in utilization, convenient, easily produce, popularization.

Description of drawings

Below in conjunction with accompanying drawing and concrete enforcement the utility model is done further detailed description.

The specific embodiment

In Fig. 1, power switch 1, power supply 2 are connected with PTC front end 3, and PTC rear end 4 directly joins with hard contact 6, and Heat Conduction Material 7 directly is adhered to pen a body 8 and a body lower body 9 on one's body, and heat is distributed evenly.

As shown in Figure 2, originally add heat pen described pen on one's body body 8 upper end internal fixation be provided with power supply 2, connect heater PTC front end 3 by wire, wire is connected to the two poles of the earth of power supply 2 more at last through power switch 1, pen body 8 tops is on one's body set up power switch 1, heater PTC rear end 4 two hard contacts 6 of body 8 upper ends on one's body pen link to each other, can make heater PTC5 be fixed on the pen upper end of body 8 on one's body like this, and make heat be difficult for loss, pen is body 8 on one's body, the body lower body 9 inner evenly bonding Heat Conduction Materials 7 of going up, heat is evenly discharged, reduce energy loss, improve the security of process.

Claims (3)

1. one kind adds heat pen, by power switch, power supply, PTC front end, PTC rear end, PTC, hard contact, Heat Conduction Material, form on one's body by body, a body lower body and nib for pen, it is characterized in that: electro-heat equipment PTC directly is connected with hard contact, Heat Conduction Material directly is adhered to a body, and the pen top internal fixation of body on one's body is provided with power supply.

2. a kind of heat pen that adds according to claim 1 is characterized in that: the switch of power supply is arranged on the pen top of body on one's body, and two poles connects the two ends, front of electro-heat equipment PTC by wire.
