AI Technical Summary
When a sharp object punctures the airbag of a current bulletproof and stab-resistant life vest, all the internal air leaks out, making it unable to provide continuous buoyancy and reducing safety.
Design a puncture-resistant inflatable life jacket comprising two front bodies and one rear body, with an internal inflation component and a protective component. The inflation component is connected to the outer and inner air bladders via an air pump and an air inlet pipe. The protective component ensures buoyancy even if the outer air bladder is punctured via an air column and a sealing strip.
It enables the internal airbag and air column to continuously provide buoyancy when the external airbag is punctured, improving safety and ensuring that the life jacket can still provide buoyancy when it encounters a puncture, thus enhancing safety.
