Abstract
The utility model discloses a novel electric warming writing pen, aiming to provide an electric warming writing pen which has high safety and reliability, simple structure, lower cost and convenient use. The utility model comprises a pen core and pen casing. The pen casing is provided with a heat insulation layer, an exothermic body and an insulating heat conductor from inner to exterior, and the exothermic body is connected with a power connection of the pen end by a conducting wire. The utility model can offer the writer with hands warming under the cold condition.
Description
Technical field
The utility model relates to the lettering pen class, and more particularly, it relates to the warm lettering pen of a kind of electricity.
Background technology
At present, the lettering pen of selling on the market is of all kinds, for example pen, ball pen, pencil etc., and its function often only limits to write purposes.Yet China is vast in territory, makes a clear distinction between the four seasons, in the season of cold,, still have considerable people because the popularity rate of air-conditioning is also not high, student particularly, the study of unconditionally writing in air-conditioned room is temporarily frozen hand and has been brought great inconvenience for their activity of writing because cold.Up to the present, do not see the lettering pen that can warm up hand on the market as yet.
Summary of the invention
The purpose of this utility model has been to break through the limitation of existing lettering pen function singleness, and a kind of warm lettering pen of electricity with warm hand function is provided.
Electricity of the present utility model warms up lettering pen, comprise a pen core and a shell, described shell is outside equipped with thermal insulation layer, heater and insulating heat-conductive layer by the lining, described heater is connected with the power connection of pen end by lead, described power connection is connected with the power supply that is not higher than 220V, preferably be connected with the power supply that is not higher than 36V, the operating temperature of described case surface is no more than 45 ℃.
The beneficial effects of the utility model are as follows:
1. reliability height can voltage power supply safe in utilization; 2.Good heating effect can warm up hand when writing; 3.Simple in structure, with low cost, easy to use, be fit to extensively promote.
Description of drawings
Accompanying drawing is the structural representation of the warm lettering pen of novel electricity
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
In the drawings, the warm lettering pen of novel electricity mainly is made of a pen core 1 and a shell 2, and described shell 2 is outside equipped with thermal insulation layer 3, heater 4 and insulating heat-conductive layer 5 by the lining, and heater 4 is connected with the power connection 6 of pen end by lead; Described heater 4 can adopt thermistor, is made by semi-conducting material, can come design temperature by the prescription of adjusting semi-conducting material, and according to the requirement of the warm lettering pen of this electricity, the operating temperature of a shell can not be higher than 45 ℃.
The external power supply of the warm lettering pen of this novel electricity can be an AC power, also can be dc source, and its power source voltage that connects can not surpass 220V, preferably adopts the safe voltage that is not higher than 36V.
