[0002] Life jackets, also known as life vests, are life-saving clothing. They are designed similarly to vests and are made of nylon fabrics or neoprene, buoyant materials or inflatable materials, reflective materials, etc. They are generally used for 5-7 years and are one of the life-saving equipment on ships and airplanes. They are generally vest-style and made of foam plastics or cork. They have enough buoyancy when worn on the body to keep the head of the drowning person above the water.

[0003] For example, the Chinese authorized patent with announcement number CN209833958U (an inflatable life jacket) comprises a life jacket body and a gas generator, wherein the gas generator comprises a trigger switch and a plurality of combustion chambers, wherein the plurality of combustion chambers are ignited by the trigger switch, wherein the interior of the life jacket body is divided into a plurality of air bags, wherein the air outlets of the plurality of combustion chambers are connected one-to-one with the air inlets of the plurality of air bags, wherein the combustion chamber comprises an air outlet pipe, wherein the air outlet is located at the free end of the air outlet pipe, wherein a coolant layer is arranged in the air outlet pipe, and by arranging a plurality of air bags, and each air bag adopts a separate combustion chamber to supply air thereto, and each combustion chamber is centrally ignited and burned by the same trigger switch, so that the gas is quickly filled into the corresponding air bag, thereby increasing the inflation rate in the entire life jacket, which is beneficial to ensuring the safety of personnel.

[0004] However, the inflatable life jacket in the above-mentioned prior art cannot adjust the internal inflation volume, so that its buoyancy cannot be adjusted, and it cannot be adjusted for breathing for different users, which affects its flexibility of use; therefore, it does not meet the existing needs. In this regard, we propose an inflatable life jacket with adjustable buoyancy. Utility Model Content
