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.
