[0040] See also Figure 1-Figure 9 As shown, the present invention provides an anti-hypothermia marine life jacket with positioning and position information sending functions, including a body jacket 100 provided with an inner liner filled with gas and a Beidou information terminal 130 installed on the chest of the body jacket 100, and the Beidou information terminal 130 integrates a Beidou positioning module, a mobile communication module, a control processing module and a power management module; the Beidou positioning module continuously receives Beidou satellite signals, calculates the current position information of the life jacket, and transmits this information to the control processing module; the control processing module processes the received position information; the mobile communication module sends the position information to the fishing vessel safety and rescue information service center platform through the mobile communication network;

[0041] That is, the Beidou information terminal 130 accesses the Internet and the fishing boat safety and rescue information service center platform through a mobile base station and a mobile gateway to perform unified information processing, storage and display to achieve user tracking and monitoring; the above is the prior art and will not be repeated here;

[0042] Specifically, in order to allow the user to maintain body temperature when wearing a life jacket to resist the low temperature at sea or even in the sea, a thermal insulation kit 200 of matching size is sewn on the inner side of the body armor 100. The body armor 100 is a pullover wearable vest structure, that is, its front side is closed; a closed temperature storage area is formed on the inner side of the body armor 100 to separate the body from the low-temperature air and seawater; a heating component 300 is provided on the chest of the body armor 100 to supply hot gas between the thermal insulation kit 200 and the body armor 100, so as to form a thermal insulation layer surrounding the body, and further prolong the time of maintaining body temperature, so that the user can wait for rescue safely;

[0043] The thermal insulation kit 200 includes a body protector 210 that forms a closed inner cavity with the body protector 100, a neck protector 220 disposed in the middle of the top surface of the body protector 210, and a neck bag 230 disposed on the top of the body protector 210; the neck bag 230 is inflated and closely attached to the neck to form a state of isolating the outside air and seawater; the body protector 210 is made of silica gel and has a vest structure with an opening at the bottom, the neck protector 220 is connected to the body protector 210, and cuffs 211 are provided on the left and right sides of the top of the body protector 210 for the user to wear and use normally;

[0044] The heating component 300 includes a storage part 310 on which a piezoelectric ceramic sheet and a solid fuel are placed, a spring-beating part 320 slidably connected to the outer side of the storage part 310, and a connecting sleeve 330 for penetrating the body armor 100 and sleeved with the storage part 310; when the piezoelectric ceramic sheet is subjected to an external force, such as impact or vibration, charge separation will occur to form an electrostatic field; as the charge accumulates, it will eventually lead to the occurrence of a discharge phenomenon, that is, electric sparks; the solid fuel is preferably sodium azide, and when sodium azide is heated, it will quickly decompose to produce nitrogen and metallic sodium; the reaction process is very rapid, and the required amount of gas can be provided to the airbag in a very short time;

[0045] The striking member 320 is used to strike the piezoelectric ceramic sheet placed inside the storage member 310 to generate electric sparks to ignite the solid fuel to release hot gas, which then fills the closed inner cavity between the body protection sleeve 210 and the body protection garment 100, forming a heating layer to protect the body temperature.

[0046] Furthermore, a neck cover 120 is connected to the middle of the top of the body armor 100, and short sleeves 110 are connected to the left and right sides of the top of the body armor 100. The outer side of the bottom end of the body armor 210 is aligned and sewn with the inner side of the bottom end of the body armor 100, the outer side of the top end of the neck cover 220 is aligned and sewn with the inner side of the top of the neck cover 120, and the outer side of the cuff 211 is aligned and sewn with the inner side wall of the short sleeve 110, so that a heat-insulating cavity from the bottom end to the neck is formed between the body armor 210 and the body armor 100, thereby surrounding and protecting the body;

[0047] An air valve 240 is embedded on the outside of the neck bag 230, and an air bag 140 is hung on the neck cover 120 and is plugged into the air valve 240 to inflate the neck bag 230; by repeatedly squeezing the air bag 140, the neck bag 230 can be expanded and tightly attached to the neck to form a closed state.

[0048] Specifically, the storage member 310 is composed of a flat cylindrical sheet placement sleeve 311 and a long cylindrical material placement sleeve 312 which are coaxial and integral. The outer diameter of the sheet placement sleeve 311 is larger than the outer diameter of the material placement sleeve 312, and the inner cavities of the two are connected and pass through the outer end of the material placement sleeve 312, so that materials can be put into the opening end of the material placement sleeve 312; the piezoelectric ceramic sheet and the solid fuel are respectively placed in the inner cavities of the sheet placement sleeve 311 and the material placement sleeve 312; the inner cavity of the material placement sleeve 312 is provided with a material storage sleeve 316 with openings at both ends, and the solid fuel is filled in the storage sleeve 316 for easy access; the storage member 310, the piezoelectric ceramic sheet and the solid fuel are used in a matching manner so that they can be replaced in time after one use.

[0049] Furthermore, a heat transfer hole 101 is opened on the chest of the body armor 100, and the connecting sleeve 330 is tightly fitted with the heat transfer hole 101, and glue is applied at the gap to form a sealed state; the connecting sleeve 330 is provided with a circular ring-shaped sealing piece 331 facing the inner end of the body armor sleeve 210, and the sealing piece 331 is made of silicone material to form a circular ring sheet structure, and the inner hole diameter of the sealing piece 331 is smaller than the inner diameter of the storage sleeve 316, which is used to prevent the solid fuel combustion in the storage sleeve 316 from entering between the body armor sleeve 210 and the body armor 100, and only allow the gas with heat to pass in; a U-shaped connecting block 332 is provided on the outer side of the outward end of the connecting sleeve 330, and a sealing cover 340 is clamped on the outside of the connecting block 332, which is used to seal the storage piece 310 and the hitting piece 320 to avoid touch-free operation.

[0050] Specifically, recessed holes 313 are provided on the top and sides of the sheet-mounting sleeve 311, wherein the recessed hole 313 on the side penetrates the inner cavity of the sheet-mounting sleeve 311, and a sealing film 315 is bonded inside the recessed hole 313 to seal the piezoelectric ceramic sheet and isolate it from the outside. The sealing film 315 is a paper film or a plastic film so that the spring-beating member 320 can penetrate and contact the piezoelectric ceramic sheet.

[0051] The arc edge of the plate sleeve 311 is symmetrically provided with a slide rail 314 between a pair of concave holes 313. The cross section of the slide rail 314 is an inverted L-shaped, thereby forming a limit knot; the striking member 320 includes a nail 321 inserted into the concave hole 313, a spring 322 sleeved on the outside of the nail 321, and a sliding sleeve 323 engaged and slidably connected with the pair of slide rails 314; the top of the nail 321 is a plastic end and insulated. Under normal circumstances, the nail 321 is inserted into the top. When in use, the driving pin 321 is pulled out of the recessed hole 313, and then slides along the slide rail 314 to the recessed hole 313 on the side until they overlap. The driving pin 321 instantly pierces the sealing film 315 under the action of the rebound force of the spring 322, and hits the piezoelectric ceramic sheet to generate electric sparks, thereby igniting the solid fuel to release heat gas, which diffuses to the space between the body guard 210 and the body guard 100 through the heat transfer hole 101 to form a heating layer.

[0052] Furthermore, the sleeve 323 and the driving pin 321 are slidably sleeved, and the upper and lower ends of the spring 322 are respectively welded to the top of the driving pin 321 and the top surface of the sleeve 323. Since the sleeve 323 and a pair of slide rails 314 slide in a limited manner, the lower end of the spring 322 is pulled and rebounds to pull the driving pin 321 to extend into the plate sleeve 311 until the driving pin 321 slides to the side recessed hole 313 and can be instantly inserted to form an impact force; wherein the contraction length of the spring 322 is greater than the distance between the inner end of the recessed hole 313 and the piezoelectric ceramic sheet, so that after the spring 322 retracts, it pulls the driving pin 321 to move axially and can touch the piezoelectric ceramic sheet.

[0053] In addition, in order to prevent cold air or seawater from entering the torso armor 100, the insulation time of the torso armor 210 is extended, so that the user can wait for rescue safely; the short sleeve 110 is provided with an arm guard 400 for closing the arm to prevent cold air or seawater from entering the torso armor 210 from the short sleeve 110; the arm guard 400 includes an elastic arm guard 410, a palm guard 420 fixedly connected to the outer end of the arm guard 410, and an arm bag provided at the connection between the arm guard 410 and the palm guard 420 430, the arm guard 410 is made of latex and is cylindrical, and its inner end is aligned and bonded with the inner end side wall of the short sleeve 110, so that the arm guard 410 is closed and connected with the short sleeve 110; the outer side of the arm bag 430 is embedded with a valve 240, the outer end of the palm cover 420 is in a closed state and a finger hole 421 is opened on one side; the top of the inflatable bag 140 is hung with an elastic rib, and the upper end of the elastic rib is fastened with a ring 141 that is sleeved with the neck cover 120, so that the inflatable bag 140 can be stretched to inflate the arm bag 430;

[0054] When wearing the body protector 100, after the arm is inserted into the arm guard 410, the palm is passed through the palm guard 420, and the thumb is passed through the finger hole 421. After the arm is stretched out, the arm guard 410 is stretched to cover the entire arm, and then the arm bag 430 is inflated with the air bag 140 to expand it and fit closely to the skin, forming a closed state;

[0055] The bottom end of the body armor 100 is provided with a waist protector 500 for closing the waist and abdomen to prevent cold air or sea water from entering the body armor 210 from the short-sleeved sleeve 110; the waist protector 500 includes an elastic waist armor 510 and a waist bag 520 arranged on the top of the waist armor 510, and an air valve 240 is embedded on the outer side of the waist bag 520. The waist armor 510 is made of an elastic belt, and a sewing edge 511 bonded to the bottom surface of the body armor 100 is sewn on the top of the waist armor 510, so that the waist armor 510 is closed and connected to the body armor 100; the waist armor 510 is pressed against the waist and abdominal skin to fit, and then the waist bag 520 is inflated by the air bag 140 to fit tightly against the waist and abdominal skin to form a closed state.

[0056] When using the anti-hypothermia marine life jacket with positioning and position information sending function of the present invention, the body armor 100 is first worn as a whole outside the upper body, the arm is inserted into the arm guard 410, the palm is passed through the palm guard 420, and the thumb is passed through the finger hole 421, and the arm is stretched out to stretch the arm guard 410 to wrap the whole arm; then the waist guard 510 is put on in contact with the skin, and then the inflatable bag 140 is used to inflate the valve mouth 240 of the neck bag 230, the arm bag 430 and the waist bag 520 in turn, so as to form a closed environment between the body guard 210 and the upper body close to the skin, thereby initially forming a heat preservation space that isolates the external cold air and seawater;

[0057] When the user needs rescue, the mobile communication module of the Beidou information terminal sends the current location information to the fishing vessel safety and rescue information service center platform via the mobile network, connects to the Internet and the fishing vessel safety and rescue information service center platform, and processes, stores and displays the information in a unified manner, so as to track and monitor the user and launch rescue operations;

[0058] At the same time, if the user encounters a situation where the body temperature drops or floats in the sea water, the user opens the cover 340 and pulls out the driving pin 321 to disengage the recessed hole 313 located above the sheet sleeve 311, and then slides along the slide rail 314 to the recessed hole 313 located on the side of the sheet sleeve 311 until they overlap. The driving pin 321 instantly pierces the sealing film 315 under the action of the rebound force of the spring 322, and hits the piezoelectric ceramic sheet inside the sheet sleeve 311 to generate an electric spark, which then ignites the solid fuel to release heat gas, which diffuses to the space between the body protector 210 and the body protector 100 through the heat transfer hole 101, forming a heating layer, and further prolonging the time for maintaining body temperature, so that the user can safely wait for rescue.
