Description

technical field [0001] The invention relates to an electric heating hand warmer, in particular to a portable battery hand warmer. Background technique [0002] At present, there are many types of hand warmers in the market, such as electric hot water bottle, hand warmer, electric cake and so on. This kind of hand warmer is all heated by high voltage to reach a certain set temperature and then heated. Due to the use of high voltage heating, the safety risk factor is large. Because of the need for insulation, it has many layers of thermal conductivity, and the temperature rises slowly when it is turned on. The material is thick, the product is bulky, it is inconvenient to carry, it cannot be used at any time, and it cannot be used when it is heated by electricity. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a portable battery hand warmer for overcoming the above defects and deficiencies, which is small and light, can be used anytime,...
