Description

The present invention relates to a wearable personal safety protection terminal, and specifically to a field of wearing equipment technology.

Many people have a hobby of swimming outdoors in lakes, but lack of safety measures causes drowning accidents and is a problem that cannot be overlooked for the safety protection of swimming.
Currently, as a safety protection device for swimming, there are large-sized equipment such as floats and kickboards, which are inconvenient to carry and have restrictions on use, and most people carry the above device when swimming outdoors. To solve the above problem, we provide a protective device that can be worn and is on the verge of drowning in a timely manner.
Commercially available life-saving bracelets generally require that the airbag be filled with air by a tank filled with compressed gas during drowning, and the gas tank must be replaced each time it is used.Since the capacity of the gas tank is fixed, the amount of gas in it is the weight. It is difficult to apply to different people, and in the case of users with a larger body shape, it may not float due to lack of buoyancy. The present invention makes improvements to the above problems.
