Electric hand warmer based on electromagnetic principle

Abstract

The present invention proposes an electric hand warmer based on the electromagnetic principle, which is characterized in that: it includes a heating part; it includes a closed main body containing water inside and a heating element placed in the closed main body, and the closed main body is provided with a The water inlet of the cavity, the heating element is a hollow iron shell, which floats or suspends in the water body; the base part includes the base body and the power circuit built in the base body, the base body has a platform for placing the heating part, the base body An electromagnetic coil connected with the power circuit is arranged on the platform. The invention abandons the traditional electrode active contact heating method, the heating part does not involve active devices, the cost is lower and the heating is safer; in addition, the heating part and the base part can be separated, and when the water body needs to be heated, it will generate heat Parts can be put back on the base, no need for wiring and switch operation, very convenient and fashionable.

Description

technical field [0001] The invention relates to an electric hand warmer based on the electromagnetic principle. Background technique [0002] When the weather is cold, people often use warm water bags to keep warm. The traditional water-filled warm water bags maintain the temperature by adding hot water. Not only is the process of adding water cumbersome and wastes water resources, but also it is easy to be scalded by hot water if the operation is not careful. . In this regard, the existing technology uses electrode heating to solve the problem of water heating. However, since the electrodes are directly hidden in the hot water bag, they may come into contact with the water after long-term use, and the production quality supervision is weak, so leakage and explosion are prone to occur. and other dangerous situations; the reason is caused by the active contact heating method of electrode heating, which needs to be solved urgently. Contents of the invention [0003] Based ...
