Abstract

一种学习用笔,涉及一种冬天使用可以发热的笔,属于文具。它包括笔杆和笔头,在笔杆的顶端设有一个夹片,其特征是,所述的笔杆为导热性好的材料制成,笔杆内部均匀的分布有电热丝,笔杆外部设有电热丝的工作开关;所述的夹片内部设有纽扣电池的电池仓;电池、开关和电热丝由导线依次连接组成工作电路;电热丝设定温度上限不超过50度。冬天写字时手比较冷,但是写字时不能够戴手套,这时将笔杆上的开关打到“开”的状态,笔杆内部的电热丝通电发热,人们握住笔时就会感觉很温暖,不会再因为手太冷而感觉写字不方便。电热丝设定了温度上限,防止电热丝温度太高烫手。
A learning pen relates to a pen capable of heating in winters, belonging to stationery, which comprises a penholder and a pen head, wherein the top end of the penholder is provided with a clamping piece. The learning pen is characterized in that the penholder is made from material with excellent heat conductivity, electric-heat wires are evenly distributed inside the penholder, an operating switch of the electric-heat wires is arranged outside the penholder, the inner portion of the clamping piece is provided with a battery bin of button batteries, and the batteries, the switch and the electric-heat wires are connected by wires in turn to form an operating circuit, and the set upper temperature limit of the electric-heat wires does not exceed 50 DEG C. People feel cold when writing in winter, but can not wear gloves to write, however, then the switch on the penholder can be opened, and the electric-heat wires inside the penholder are electrified to heat, people can feel warm when holding the pen, and never feel inconvenient to write owing to feeling cold. The electric-heat wires are set with the upper temperature limit, which can prevent temperature of electric-heat wires from being overhigh to scald hands.
