A portable anti-drowning dual-purpose lifesaving device and its working principle

Abstract

The invention discloses a portable anti-drowning dual-purpose lifesaving device and a working principle thereof. The device comprises a reactor and an oxygen gasbag, the reactor is connected with the oxygen gasbag through a first pipe, a one-way valve is arranged on the first pipe, and by means of the one-way valve, air inflation can only be conducted from the reactor to the oxygen gasbag; the reactor is connected with a one-way water inlet valve, sodium peroxide is placed in the reactor, the surface of the sodium peroxide is coated with a chemical protecting film, and a negative pressure cavity is formed inside the reactor; multiple acid acceptors are arranged inside the oxygen gasbag; a mouth-control oxygen supply valve is arranged on the oxygen gasbag; the one-way water inlet valve is connected to a start switch. The working principle is ingenious in design, and two lifesaving functions, namely the floating and oxygen supplying, are achieved on the lifesaving device. Compared with the prior art, the device has the advantages that according to the size and weight, the lifesaving device is convenient to carry even wear, and normal activities are not affected; the device can be used independently as lifesaving equipment, and the device and a belt or a watch can be made into a whole as well.

Description

technical field [0001] The invention relates to a lifesaving device, in particular to a portable anti-drowning dual-purpose lifesaving device and its working principle. Background technique [0002] At present, the drowning life-saving equipment in the life-saving field mainly has the following problems: 1. Poor portability: conventional life buoys, life jackets, diving suits, etc. have poor portability and cannot be carried around. Therefore, it cannot be obtained in time in an emergency, which is one of the important reasons for accidents. 2. Existing similar portable life-saving devices adopt high-pressure gas cylinders to inflate, but their portability is not enough. 3. The existing similar chemical reaction inflatable life-saving device produces carbon dioxide gas, which can only be used as a buoyancy life-saving device, and cannot play a life-saving role when oxygen is needed for escape in a watertight space in a shipwreck accident.
