The invention discloses a closed water storage type emergency breathing device which comprises a floating plate, a telescopic breather pipe, a water storage cylinder, a closed assembly and a breathing mask. When the device is used, the floating plate and the water storage barrel are separated firstly, the floating plate floats in water, external water can enter a ventilation opening of the floating plate and enter the water storage barrel from a telescopic ventilation pipe in the upward floating process of the floating plate, and after the floating plate floats, a closed piston plate is driven to move downwards through rotation of an adjusting rod; when the sealing piston plate moves downwards, the expansion pipe body is driven to expand downwards at the same time, so that water in the telescopic ventilation pipe and the water storage barrel moves downwards, and when the sealing piston plate moves downwards to the position below the telescopic ventilation pipe, the water is sealed in the lower portion of the water storage barrel. Thus, a dry ventilation path is achieved through the ventilation opening of the floating plate, the telescopic ventilation pipe, the interior of the upper portion of the water storage barrel, the opening and closing pipe and the breathing mask, normal ventilation is not affected, and flexible drainage and stable use are achieved.

    本发明公开了一种封闭储水式应急用呼吸装置,包括浮板、伸缩通气管、储水筒、封闭组件、呼吸面罩;本发明在使用时,首先将浮板和储水筒进行分离,浮板漂浮于水中,浮板向上漂浮的过程外部水会进入浮板的通气口,并从伸缩通气管进入储水筒内,当浮板漂浮之后,通过调节杆转动,并驱动封闭活塞板向下移动,封闭活塞板向下移动的同时带动扩张管体向下扩张,如此伸缩通气管以及储水筒内部的水会向下移动,当封闭活塞板向下移动至伸缩通气管的下方时,如此将水封闭于储水筒的下方内部,如此浮板的通气口、伸缩通气管、储水筒的上方内部、启闭管、呼吸面罩实现干燥的通气路径,不影响正常通气,如此实现灵活排水、稳定的使用。
