Description

technical field [0001] The present application relates to a life preserver, in particular to a drowning life preserver. Background technique [0002] With the continuous growth of the national economy and the significant improvement of material living standards, water sports have increasingly become the summer sports of choice for the general public. With the rising trend of swimming, drowning has also become a high incidence of swimming safety problems in summer.

Problems solved by technology

When the human body falls into the water and the body is submerged, the mouth and nasal cavity are filled with water, which prevents the entry of oxygen. At the same time, the stimulation of cold water or water absorption will cause reflex pharyngospasm, which is prone to suffocation

[0003] At present, the existing lifebuoys that can be worn while swimming include lifebuoys, life jackets and inflatable wall rings. , the lifeguard can usually make the swimmer float on the water, but it cannot guarantee that the swimmer can swim in the water normally, that is, he cannot enjoy the normal swimming fun, but if he does not wear the above equipment, there is a risk of drowning
