AI Technical Summary
Most existing self-inflating neck-mounted life jackets have a single-layer air chamber structure, which is prone to gas leakage when damaged. Furthermore, people who fall into the water are prone to rapid hypothermia, leading to loss of consciousness.
A life jacket with a dual-cavity structure was designed. Two sets of air inlets are connected to the first and second cavities respectively. A graphene heating element is set on the inside. The dual cavities are inflated and provide buoyancy when they come into contact with water using an automatic inflation mechanism. At the same time, the graphene heating element provides heat under power supply to prevent temperature loss.
It features dual air chamber protection to prevent gas leakage and provides heat through a graphene heating element to raise the body temperature of the person falling into the water, ensuring safety and maintaining consciousness.
