The invention discloses a portable drowning lifesaving device which comprises a bottom reaction unit, a shell, an air bag and a top knob switch unit. The folded air bag is placed in a right side of the shell, and several binding belts are arranged at one end of the shell. When the whole device is in water, the top knob switch unit is turned on so that the air bag is unbound; a first spring pushesthe air bag out from the inside; meanwhile, external water is sucked into a mounting groove through the through holes in the mounting groove; after the first spring extends to a certain extent, pressure on a second spring is weakened; the second spring starts to extend to push a gasket; a supporting insertion plate is pushed by the first spring to be tightly pressed at a through hole bulge of themounting groove; and after the whole locking block is pushed away by the gasket, chemical substances in the mounting groove make contact with water entering the mounting groove previously to generatea large amount of gas, the air bag is in a sealed state, the large amount of gas is generated in the air bag to enable the air bag to be inflated rapidly, and buoyancy is provided for a user to achieve a self-rescue function.

    本发明公开了便携溺水救生装置,包括底部反应单元、外壳、气囊和顶部旋钮开关单元,所述外壳右侧内部放置有折叠好的气囊,所述外壳一端有几道绑扎带。本发明当整个装置在水中时,旋钮开顶部旋钮开关单元使得气囊被解除束缚,第一弹簧将气囊从内部推出,同时通过安装槽上的通孔将外部的水吸入内部,第一弹簧伸展开一定程度后对第二弹簧的压力减弱,第二弹簧开始伸展推动垫圈,支撑插板被第一弹簧推动紧压于安装槽的通孔凸起处,垫圈将锁紧块整个推离后,安装槽内部的化学物质与之前进入内部的水接触产生大量气体,气囊处于密封状态,大量的气体在气囊内部生成使得气囊快速充气,为使用者提供浮力以实现自救功能。
