The life-saving ball comprises a ball body, the ball body is provided with an inlet and outlet and a containing cavity, first air cavities and a through hole are formed in the ball body, the ball body is further provided with an inflation nozzle, a first one-way valve is arranged between every two adjacent first air cavities, each first one-way valve comprises a sliding block and a first elastic piece, and the sliding block is provided with an air inlet channel and an air outlet channel; a connecting channel is formed in the inner side wall of the through hole, when air enters the first air cavity gradually, the sliding block moves to enable the air inlet channel and the air outlet channel to communicate with the connecting channel, inflation is achieved, and when the air in the first air cavity communicating with the air outlet channel is saturated, the sliding block moves away from the first air cavity communicating with the air outlet channel under the action of the first elastic piece, and the air in the first air cavity communicates with the air outlet channel. The air inlet channel and the air outlet channel are staggered with the connecting channel, one-way communication is achieved, in the using process of the ball body, if one first air cavity breaks, under the action of the first one-way valve, the other first air cavities can continue to play a role to achieve the rescue effect, and the using reliability of the lifesaving appliance is improved.

    本申请涉及一种救生球,其包括球体,球体上开设有出入口和容纳腔,球体内设有气腔一和通孔,球体上还设有充气嘴,相邻两个气腔一之间设有单向阀一,单向阀一包括滑块和弹性件一,滑块上设有进气通道和出气通道,通孔的内侧壁上开设有连接通道,当气腔一内逐渐进气时,滑块发生移动使进气通道、出气通道均与连接通道连通,实现充气,当与出气通道连通的气腔一内的气体饱和,滑块在弹性件一的作用下移动远离与出气通道连通的气腔一,使得进气通道、出气通道均与连接通道错开,实现单向导通,在球体使用过程中,若有气腔一发生破裂,在单向阀一的作用下,其余部分气腔一可继续发挥作用实现救助效果,提高了救生器具使用的可靠性。
