Description

technical field

[0001] The invention belongs to the field of lifesaving devices and relates to a lifesaving device for preventing drowning. Background technique

[0002] The anti-drowning lifesaving device is a relatively common safety device. This device is mainly used to prevent suffocation caused by drowning when personnel accidentally fall into the water or near the water. At present, the common life-saving devices on the market mainly include wearable and There are two types of external projection.

[0003] The wearable life preserver is usually worn on the user's wrist or collar. In the event of a drowning accident, the user opens the high-pressure gas valve by pulling the trigger mechanism or automatically triggering by external conditions (such as immersion in water, etc.), so that the high-pressure gas is filled into the foldable life preserver. The airbag of the life preserver is used to lift the user out of the water by the buoyancy of the life preserver. This ki...
