Abstract

The invention discloses an underwater life-saving device, which comprises a sealed shell, wherein a high-pressure gas chamber is arranged in the shell, a gas leakage hole is formed in the high-pressure gas chamber and externally connected with an air bag, a ventilation device for opening the gas leakage hole is also arranged beside the gas leakage hole, the air bag is stored in the shell in a deflation state, a water pressure sensor and a power supply are also arranged in the shell, the water pressure sensor is connected with the ventilation device through a control circuit board and controls the action of the ventilation device, and the water pressure sensor, the control circuit board and the ventilation device are all connected with a power supply; and the shell is externally provided with a fixing piece being fixed together with a human body. Firstly, the device is small in size, and can be fixed on the body through the fixing part without generation of the use discomfort, and the long-time swimming of a user underwater is not affected.

Description

Technical field: [0001] The invention relates to the technical field of life-saving equipment, in particular to an underwater life-saving device. Background technique: [0002] In order to prevent drowning accidents, people with poor water quality, especially teenagers and children, need to wear life jackets or hold life buoys when swimming, which can ensure the safety of personnel to a large extent, but it is very inconvenient and comfortable to wear life jackets when swimming. Poor, lifebuoys generally provide safety protection for people who cannot swim, that is to say, common life jackets or lifebuoys are not suitable for people who can swim in the water, and guaranteed lifesaving equipment is necessary, especially in Swimming in unfamiliar waters or teens swimming alone without parental supervision, therefore, it is necessary to design a life-saving device that is easy to use and does not hinder normal swimming. Invention content: [0003] In order to solve the above...
