Problems solved by technology

[0003] 1) When the person entering the water stays in the water for a long time (such as in the sea or a lake) and has not been rescued, due to his physical exhaustion to exhaustion, the person entering the water will sink and be separated from the lifebuoy, and the life jacket will also be affected by the buoyancy. Insufficient (usually the inner material of the lifejacket is plastic foam) to sink the person entering the water

[0004] 2) When people swim in the water, they often choose to give up using lifebuoys and lifejackets because of their large and clumsy bodies, which brings great unsafe hidden dangers to swimmers

[0005] 3) The lifebuoy or lifejacket cannot enable the wearer to dive, which reduces the fun of swimming; while swimmers who do not wear the lifebuoy or lifejacket cannot rescue themselves if an accident occurs during diving
