Abstract

The invention discloses a portable and safety multifunctional hand warmer. The multifunctional hand warmer comprises a charging power source, a power source heat-insulating and anti-explosion layer, a temperature sensing controller, an electric heating wire, a temperature rise insulating layer, an aluminum film conducting layer, a fluff layer, an inner charging module, an outer charging module, a power source, a temperature and electric quantity displayer and an abnormity alarm module. Potential hazards such as leakage and overheating explosion of a liquid hand warmer can be avoided, safety of the multifunctional hand warmer is improved, the hand warmer is provided with the own power source to conduct charging and discharging, and the requirement for outdoor carrying is met fully, which is beneficial for market application and popularization.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of hand warming bags, in particular to the technical field of a portable and safe multifunctional hand warming bag. [0003] 【Background technique】 [0004] Hand warmers, as the name suggests, can warm people's hands or other parts. The hand warmer uses the liquid in the hand warmer to transfer heat. Generally, it is widely used by people in winter. The liquid in the hand warmer is the supersaturated solution of sodium acetate. Because the concentration of the supersaturated solution is too high, it is not stable. When we twist the metal sheet inside, the slight shock produced is enough to cause the solute to crystallize into a more stable solid. However, the process is exothermic, so the hand warmer starts to warm up. One advantage of hand warmers is that they can be recycled. As long as the hand warmer is placed in boiling water and heated for about 10 minutes, the condensed solute will be di...
