[0019] Please see Figure 1-4 This utility model provides a technical solution: a foldable multi-functional foam life jacket, including a front shoulder foam fabric 1, a fixing rope 2 passing through one side surface of the front shoulder foam fabric 1, a front chest foam fabric 3 passing through one side surface of the fixing rope 2, a buckle 4 fixedly connected to one side surface of the front chest foam fabric 3, a front waist foam fabric 5 passing through the fixing rope 2, a connecting nylon rope 6 fixedly connected to one side surface of the front shoulder foam fabric 1, a rear shoulder foam fabric 7 fixedly connected to one side surface of the connecting nylon rope 6, a rear chest foam fabric 8 fixedly connected to one side surface of the connecting nylon rope 6, a waterproof light strip 9 fixedly connected to one side surface of the rear chest foam fabric 8, a rear waist foam fabric 10 fixedly connected to one side surface of the connecting nylon rope 6, and a multi-functional life-saving mechanism 11 provided on one side surface of the front chest foam fabric 3;
[0020] The multi-functional lifesaving mechanism 11 includes a fixed foam board 1101, a first trough 1102, a small oxygen tank 1103, an air hose 1104, an inhalation mask 1105, a fixed fork 1106, a second trough 1107, a waterproof flashlight 1108, a fixing strap 1109, a connecting buckle 1110, a cable storage box 1111, and a whistle 1112. The fixed foam board 1101 is fixedly connected to one side of the front foam garment 3. A first groove 1102 is fixedly connected. A small oxygen tank 1103 is slidably connected to the inner surface of the first groove 1102. An air tube 1104 is fixedly connected to the upper surface of the small oxygen tank 1103. An inhalation mask 1105 is fixedly connected to the upper surface of the air tube 1104. A fixing fork 1106 is engaged with one side surface of the inhalation mask 1105. A second groove 1107 is fixedly connected to one side surface of the fixing foam board 1101. A waterproof flashlight 1108 is slidably connected. A fixing strap 1109 is provided on one side of the second groove 1107. A connecting buckle 1110 is fixedly connected to one side of the fixed foam board 1101. A cord storage box 1111 is fixedly connected to one side of the connecting buckle 1110. A whistle 1112 is fixedly connected to one side of the cord storage box 1111. The system connects the fixed foam board 1101, the first groove 1102, the small oxygen tank 1103, the air tube 1104, and the inhalation device. The inclusion of an air mask 1105, a fixing fork 1106, a second slotted tube 1107, a waterproof flashlight 1108, fixing straps 1109, a connecting buckle 1110, a cable storage box 1111, and a whistle 1112 allows the waterproof light strip 9 on the back of the foam vest 8 to function effectively at night or in low-visibility waters. Its flashing red and blue light can attract the attention of rescuers from a distance, facilitating quick location of the person in the water and improving rescue efficiency. In emergencies, such as when a person is trapped underwater for a period of time or has difficulty breathing in smoky or other adverse environments, the air mask 1105 on the fixing fork 1106 can be removed and worn, and the valve of the oxygen cylinder 1103 can be opened to breathe oxygen. The approximately ten-minute oxygen supply provides valuable time for self-rescue or while waiting for rescue. The waterproof flashlight 1108 can be taken out from the second slot 1107 for use. In the night or in a dim environment, it can be used for lighting, making it easier for the person who has fallen into the water to observe the surrounding environment, find objects to hold onto or determine their own location. At the same time, the flashlight can also send out distress signals to a distance through flashing light. It works in conjunction with the waterproof light strip 9 to enhance the distress signaling effect.The whistle 1112 is fixed to the cable storage box 1111. The paracord inside the cable storage box 1111 can be used in certain special situations, such as tying the paracord to a fixed object to prevent it from being washed away by the water flow. The whistle 1112 can be blown when rescuers are spotted or a boat is passing by nearby. Its sharp sound can be heard within a certain distance to attract the attention of others. Since the cable storage box 1111 restricts the range of motion of the whistle 1112, it can prevent the whistle 1112 from being lost.
[0021] Furthermore, the front shoulder foam fabric 1, the front chest foam fabric 3, and the front waist foam fabric 5 are connected to each other by a fixing rope 2, and the back shoulder foam fabric 7, the back chest foam fabric 8, and the back waist foam fabric 10 are connected to each other by a fixing rope 2. With the arrangement of the front shoulder foam fabric 1, the front chest foam fabric 3, the front waist foam fabric 5, the back shoulder foam fabric 7, the back chest foam fabric 8, and the back waist foam fabric, when not in use, some of the connecting knots can be untied, and the front shoulder foam fabric 1, the front chest foam fabric 3, the front waist foam fabric 5, the back shoulder foam fabric 7, the back chest foam fabric 8, and the back waist foam fabric 10 can be folded in a certain order to reduce the overall volume and facilitate storage and carrying.
[0022] Furthermore, the front shoulder foam fabric 1, the front chest foam fabric 3, and the front waist foam fabric 5 are provided with two sets on the fixing rope 2. Similarly, the back shoulder foam fabric 7, the back chest foam fabric 8, and the back waist foam fabric 10 are provided with two sets on the fixing rope 2. The front and back fabrics are fixedly connected by connecting nylon ropes 6. There are five sets of connecting nylon ropes 6 on each side of the fabric. By setting the connecting nylon ropes 6, the front and back fabrics are stably fixed together during use, making the overall structure more robust and stable, and improving the safety of the user.
[0023] Furthermore, three sets of waterproof luminous light strips 9 are installed on each side of the surface of the back foam garment 8. The waterproof luminous light strips 9 are waterproof and flash red and blue lights during use. With the installation of the waterproof luminous light strips 9, the flashing lights can form a sharp contrast with the surrounding environment when in use, making it easier for rescuers to spot the person who has fallen into the water from a distance. The combination of red and blue lights is a relatively eye-catching signal. In many rescue scenarios, this combination of two colors is widely used for emergency signal markings, which can attract the attention of rescuers and thus improve the timeliness of rescue.
[0024] Furthermore, two sets of fixing straps 1109 are provided on the upper and lower sides of one side surface of the first groove 1102 and the second groove 1107. The small oxygen tank 1103 and the waterproof flashlight 1108 can be fixed by the compression of the first groove 1102 and the second groove 1107 through the contraction of the fixing straps 1109. With the setting of the fixing straps 1109, the small oxygen tank 1103 and the waterproof flashlight 1108 can be firmly fixed during use. This avoids loss or damage that may be caused by shaking or displacement of the items, and ensures that they can function normally when these devices are needed.
[0025] Furthermore, the fixing fork 1106 is fixed to one side surface of the front shoulder foam clothing 1. The breathing mask 1105 can be easily fixed by the fixing fork 1106. The small oxygen tank 1103 can provide oxygen for about ten minutes for emergency use. With the small oxygen tank 1103, the ten-minute oxygen supply can maintain the user's basic life activities, buy enough time to wait for rescue or to save themselves. It can alleviate the user's breathing difficulties at critical moments and increase the chance of survival.
[0026] Furthermore, the cable storage box 1111 allows the whistle 1112 to move a maximum distance of three meters. Multiple sets of paracord are wound inside the cable storage box 1111. With the cable storage box 1111, whistle 1112, and paracord, the whistle 1112 and paracord can be combined together and stored in the cable storage box 1111 when in use, forming a convenient tool unit. When users need to use the whistle to send a distress signal or use the paracord for self-rescue, they can conveniently obtain both tools in one place. This design improves the efficiency of tool use and enriches the function of the life jacket, better meeting the various needs in complex aquatic environments.
[0027] Working Principle: After the user puts on the life jacket, the waterproof luminous strip 9 on the foam back panel 8 can function at night or in low-visibility waters. Its flashing red and blue light can attract the attention of rescuers from a distance, making it easier for rescuers to quickly locate the person in the water and improve rescue efficiency. In emergencies, such as when the person in the water is trapped underwater for a period of time or has difficulty breathing in smoky or other adverse environments, the breathing mask 1105 on the fixed fork 1106 can be removed and worn, and the valve of the oxygen tank 1103 can be opened to breathe oxygen. The approximately ten-minute oxygen supply time can buy the user valuable time for self-rescue or waiting for rescue. The waterproof flashlight 1108 can be taken out from the second slot 1107 and used for illumination at night or in dim environments, helping the person in the water to observe the surrounding environment, find objects to hold onto, or determine their own location. At the same time, the flashing light of the flashlight can also be used to send out distress signals to a distance, working in conjunction with the waterproof luminous strip 9 to enhance the effectiveness of the distress signal. The whistle 1112 is fixed to the cable storage box 1111. The paracord inside the cable storage box 1111 can be used in certain special situations, such as tying the paracord to a fixed object to prevent it from being washed away by the water flow. The whistle 1112 can be blown when rescuers are spotted or a boat is passing by nearby. Its sharp sound can be heard within a certain distance to attract the attention of others. Since the cable storage box 1111 restricts the range of motion of the whistle 1112, it can prevent the whistle 1112 from being lost. Furthermore, since the various garment panels are connected by the fixing rope 2 and the connecting nylon rope 6, when not in use, some of the connecting rope knots can be untied, and the front shoulder foam panel 1, front chest foam panel 3, front waist foam panel 5, back shoulder foam panel 7, back chest foam panel 8, and back waist foam panel 10 can be folded in a certain order to reduce the overall volume and facilitate storage and carrying.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
