[0002] In recent years, with the rapid development of the marine economy and the increasing frequency of maritime activities, maritime accidents have also occurred frequently. After a maritime accident, due to the poor self-rescue ability of those who fall into the water, prolonged immersion in seawater can easily lead to hypothermia, endangering their lives. Therefore, life jackets with heat-insulating properties are needed to ensure the safety of those who fall into the water. Chinese utility model patent CN213057446U discloses a "self-heating life jacket for water rescue, self-rescue, and mutual rescue," whose outer layer is woven from superabsorbent polymer resin, and a self-heating source penetrates the entire outer layer. After absorbing moisture, it expands moderately and adheres to the body surface for continuous heat replenishment, giving the life jacket self-heating properties. However, the life jackets provided by the above-mentioned prior art rely solely on the chemical reaction between chemical materials and seawater to release heat. The chemical material package is prone to moisture absorption and failure, thus affecting the use of the life jacket's self-heating function and hindering rescue efforts. Utility Model Content

[0003] In view of this, this utility model proposes a self-heating life jacket that uses seawater battery power generation to provide heat, which makes up for the shortcomings of chemical material packs that are prone to moisture and failure. It can solve the technical problem that existing self-heating life jackets rely solely on chemical material packs for heating, which are prone to moisture and failure, thus affecting the use of the self-heating function of the life jacket and hindering rescue operations.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problems of existing self-heating life jackets, such as long heating start-up time and poor heat retention, resulting in low rescue success rates and numerous casualties, this utility model designs a self-heating life jacket that employs a dual heating mode of exothermic chemical material reaction and seawater battery discharge. This shortens the heating start-up time, improves the heating performance of the life jacket, and enables it to play a greater role in emergency rescue.

[0028] like Figure 1 As shown, this utility model is a self-heating life jacket, including a life jacket body 100 and a self-heating device 200. The life jacket body has a receiving cavity. The self-heating device 200 includes a chemical material heating component 210 and a seawater battery heating component 220. The chemical material heating component 210 and the seawater battery heating component 220 are disposed in the receiving cavity. The outer walls of the chemical material heating component 210 and the seawater battery heating component 220 are in contact with the life jacket body 100 to transfer heat to the life jacket body 100.

[0029] The self-heating life jacket provided by this utility model is equipped with a chemical material heating component 210 and a seawater battery heating component 220. It provides heat to the life jacket body 100 through a dual heating mode of chemical material heating and seawater battery power supply heating. This makes up for the shortcomings of existing self-heating life jackets that rely solely on chemical materials for heating, which are prone to moisture damage and failure, thus preventing the life jacket from functioning properly. This improves the heating performance of the life jacket and is beneficial for rescue.

[0030] It is understood that the number of accommodating cavities can be single or multiple. Correspondingly, the number of self-heating devices 200 can be single or multiple. In actual use, setting the number of self-heating devices 200 to two, and placing the two self-heating devices 200 at the front two of the life jacket body 100, is the most ergonomic position. Therefore, in the preferred embodiment, the number of self-heating devices 200 is set to two.

[0031] In this embodiment, when the person in the water puts on the self-heating life jacket, seawater flows into the chemical material heating component 210 and the seawater battery heating component 220, generating heat to heat the life jacket body 100. However, in this embodiment, the self-heating device 200 is placed directly in the receiving cavity, and there is a risk of water entering the self-heating device 200 when the life jacket is not in use, which inevitably leads to unnecessary waste. Therefore, this embodiment also designs a sealing component 230 to protect the chemical material heating component 210 and the seawater battery heating component 220; at the same time, in order to ensure that the self-heating function of the life jacket can be used normally when needed, this embodiment also designs a seawater introduction component 240.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, the chemical material heating component 210 and the seawater battery heating component 220 are disposed inside the sealing component 230. The sealing component 230 has a movable end, and the seawater inlet component 240 is connected to the movable end. Under the action of external force, the seawater inlet component 240 can drive the movable end to open or close, so as to introduce seawater into the chemical material heating component 210 and the seawater battery heating component 220 or cut off the seawater inflow.

[0033] Furthermore, the sealing assembly 230 includes a housing 231 and a sealing cap 232. The housing 231 is wrapped around the chemical material heating assembly 210 and the seawater battery heating assembly 220. The sealing cap 232 is rotatably connected to one side of the top of the housing 231 to form a movable end.

[0034] Furthermore, the seawater introduction component 240 is a pull rope. One end of the pull rope is fixedly connected to the sealing cover 232. The other end of the pull rope can drive the sealing cover 232 to rotate on one side of the top of the outer shell 231 under the manual pulling force. In this way, the top of the outer shell 231 can be opened to introduce seawater or the top of the outer shell 231 can be closed to prevent seawater from flowing in.

[0035] Furthermore, the chemical material heating component 210 includes multiple chemical material packages, which are arranged side-by-side with intervals within the outer shell 231. The gaps between the multiple chemical material packages form a first seawater channel. The flowing seawater enters the first seawater channel and reacts with the chemical material packages to release heat through a chemical reaction. The chemical material packages are filled with reducing iron powder, activated carbon, and wood powder, which react with the seawater to release heat. The equation for this chemical reaction is:

[0036]

[0037] The above reaction can release a large amount of heat, and the wood flour increases the contact area of ​​the reaction, which is conducive to the complete reaction of the iron powder.

[0038] Furthermore, the seawater battery heating component 220 includes a plurality of battery electrodes 221, which are arranged side-by-side at intervals within the housing 231. The gaps between the plurality of battery electrodes 221 form a second seawater channel, and the incoming seawater enters the second seawater channel and undergoes the following battery reaction:

[0039]

[0040] The battery electrode 221 is made of aluminum. The seawater battery heating component 220 also includes a heating element 222. The heating element 222 is electrically connected to the multiple battery electrodes 221. The battery electrodes 221 generate electricity to provide power to the heating element 222. The heating element 222 is in contact with the inner wall of the outer shell 231. The heat generated by the heating element 222 is transferred to the life jacket body 100.

[0041] In this embodiment, the life jacket body 100 is heated by a dual heating method, with a combined heating temperature exceeding 40°C. This dual heating method ensures the rapid activation of the self-heating device 200, providing protection for the life safety of those who fall into the water.

[0042] Furthermore, since the exothermic reaction of chemical materials and the heating process of seawater battery discharge require the participation of seawater, and the salinity and temperature of seawater affect the reaction rate, it is difficult to accurately control the heat output in the complex marine environment, resulting in unstable heating of the life jacket, which may lead to overheating or malfunction. To address this issue, this invention designs a temperature control device 300, which can quickly stabilize the heating reaction rate and ensure the heating function of the life jacket.

[0043] Furthermore, the temperature control device 300 includes a temperature sensor and a controller. The temperature sensor is mounted on the self-heating device 200 and is used to detect the temperature of the self-heating device 200. Simultaneously, an electric push plate is also provided on the top of the outer casing 231 below the sealing cover 232. The electric push plate can be powered by an electrode battery 221. The controller is electrically connected to both the temperature sensor and the electric push plate. When the temperature sensor detects that the temperature of the self-heating device 200 is too high or too low, the controller controls the tilt angle of the electric push plate to increase or decrease the opening of the outer casing 231, thereby controlling the flow rate of seawater into the self-heating device 200 and achieving temperature control. It is understood that the above temperature control methods are common in the art and will not be elaborated upon here.

[0044] Furthermore, the life jacket body 100 includes pockets 110, and a plurality of pockets 110 are respectively located on the front and rear sides of the life jacket body 100. The pockets 110 form the receiving cavity for installing the self-heating device 200.

[0045] Furthermore, the life jacket body 100 also includes a pull ring 120, which is located on the front side of the life jacket body 100. The pull ring 120 is connected to one end of the seawater inlet assembly 240 so that a person can pull the seawater inlet assembly 240.

[0046] Furthermore, the life jacket body 100 also includes a neck protector 130, a rescue whistle 140, and a reflective strip 150. The neck protector 130 can ensure that the body of the person who has fallen into the water can remain stable in a complex maritime environment. The rescue whistle 140 is installed at the collar of the life jacket body 100. The person who has fallen into the water can blow the rescue whistle 140 to alert the rescuers after spotting them. The reflective strip 150 is located in the middle of the life jacket body 100 and can help determine the location of the person who has fallen into the water in a dark environment.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
