基于磁生电原理的手摇式便携加温盒

"节能减排"是当今中国乃至世界都极为看重的问题,而当下又是生活节奏极快的时代,人们旅游、外出或是忙于完成某种工作等很多时候都会面临一个问题--快捷食品不够健康,携带食物易变凉。本文创新性地利用磁发电原理,设计出一款基于磁生电原理的手摇式便携加温盒。通过手摇手柄使得盒盖中的磁极转动,进而产生变化的磁场。固定在盒盖内的线圈因切割磁感线产生电流,电流流经盒体内的发热电阻产生热量加热食物。本装置操作简单,方便实用,能够实现节能减排的目的,有很好的发展前景。

Energy saving and emission reduction are the most important issues in China and even the world today.However,in the era of rapid pace of life,people often face a problem when they travel,go out or are busy with some work, for example,fast food is not healthy enough and the food they carry is liable to become cold.In this paper,the principle of magnetic power generation is innovatively used to design a portable hand-held heating box based on the principle of magnetoel-ectricity.The magnetic poles in the lid are rotated by a hand crank to generate a changing magnetic field.The coil fixed in the cover of the box generates current by cutting the magnetic induction wire,and the current flows through the thermal resistance of the box body to generate heat to heat food.The device is simple to operate,convenient and practical,can achieve the purpose of energy saving and emission reduction,and has a good prospect for development.
