Description

Technical Field

[0001] The invention relates to the technical field of lifesaving equipment, and mainly to a life jacket supporting positioning alarm and drinking water functions. Background Art

[0002] At present, life jackets are generally made of low-density buoyancy materials or inflatable structures. Among them, life jackets commonly used on ships are mainly made of low-density buoyancy materials, such as natural fibers and foam plastics. In fact, when small and medium-sized cruise ships on the water encounter storms or special failures, there is a risk of capsizing, which often causes heavy casualties.

[0003] It is worth noting that many of them died despite wearing life jackets. The main reasons are: the people who fell into the water fainted due to not being able to drink water for a long time, and they may even drink a lot of sea water when falling into the water, which caused them to quickly become dehydrated and weak. In addition, staying in the water for a long time will make the bodies of the people who fell into the water colder, which can easily lead to stiffness and make it difficult for them to support for a long time. Therefore, it is necessary to design a life jacket that supports positioning alarm and drinking water functions to solve the above problems. Summary of the invention

By repeating the above operation, an appropriate amount of seawater can quickly enter the heating box, and the seawater in the heating box is heated by the heating tube, so that the seawater boils to generate water vapor, and the water vapor enters the condenser through the air outlet pipe. The water vapor entering the condenser can heat the sealed cavity, so as to warm the person who falls into the water and prevent the person from freezing. The water vapor can also be cooled by the body temperature of the person who falls into the water and the temperature of the seawater to form water droplets, which flow into the fresh water tank through the condenser. The person who falls into the water can suck out the fresh water in the fresh water tank through the water suction pipe, so as to prevent the person who falls into the water from being thirsty or even weak due to dehydration, thereby improving the survival time of the person who falls into the water, thereby improving the survival rate of the person who falls into the water.

[0029] Secondly, the present invention realizes the alarm by long pressing the alarm button to make the alarm module send out an alarm signal, and locates the position of the person who falls into the water by sending a positioning signal through the GPS positioning module, and activates the voice function through the voice module so that the person who falls into the water can describe his or her own situation. At the same time, smoke is emitted through the smoke sprayer, which makes it easier for search personnel to quickly find the person who falls into the water. BRIEF DESCRIPTION OF THE DRAWINGS

Repeating the above operation can allow an appropriate amount of seawater to quickly enter the heating box 21; then the seawater in the heating box 21 is heated by the heating tube 22, so that the seawater boils and generates water vapor, and the water vapor enters the condenser 24 through the air outlet pipe 23, and enters the condenser 24. The water vapor can heat the sealed cavity 11, thereby warming the person who falls into the water and preventing him from freezing. The water vapor can also be cooled by the body temperature of the person who falls into the water and the temperature of the sea water to form water droplets, which flow into the fresh water tank 25 through the condenser 24. Then, the bolt 32 and the extrusion plate 33 are moved by rotating the bolt 32, so that the extrusion plate 33 is moved away from the water suction pipe 26. The person who falls into the water can take out the water suction pipe 26 and suck out the fresh water in the fresh water tank 25 through the water suction pipe 26, thereby preventing the person from becoming thirsty or even becoming weak due to dehydration.
