Description

Technical Field

[0001] The invention relates to an anti-drowning automatic life-saving necklace and a working method thereof. Background Art

[0002] When a person falls into water accidentally, if the person cannot swim or loses consciousness, he will drown if he is not rescued in time. Existing life jackets and life buoys are not convenient to carry with you on a daily basis. When you fall into the water suddenly, it is difficult to get the life-saving facilities in time. Even if you wear a life-saving device on your wrist, it is difficult to ensure that the head of the person who falls into the water will always be above the water and will not drown when the person is exhausted or unconscious. Although the existing life-saving necklace can keep the head of the person who falls into the water above the water and will not drown. However, there are many shortcomings. For example, in a critical moment, it is found that the life-saving airbag is leaking, the person who falls into the water is unconscious or is in a nervous state and cannot press the life-saving switch, etc. At this time, the life-saving necklace cannot play a life-saving role.
