[0036] Example

[0037] Please refer to Figures 1 to 8 , as shown in the figure, a life preserver is provided in this embodiment, which includes a life jacket 100 and a protective helmet 200 connected to each other; the upper body and head of the human body can be protected at the same time; a plurality of first gas storage bins 110 for containing oxygen, an inflatable component, a first gas pipe 111 and a second gas pipe 121 are arranged inside the life jacket 100, the inflatable component is connected to the first gas storage bins 110, and any adjacent first gas storage bins 110 are connected to each other through the first gas pipe 111, and the inflatable component fills oxygen into the plurality of first gas storage bins 110, so that the life jacket 100 expands, which plays a protective effect of reducing impact; and The first gas storage bins 110 are each provided with a second gas storage bin 120 for accommodating carbon dioxide. Any adjacent second gas storage bins 120 are connected to each other through a second gas pipe 121, and can store carbon dioxide generated by the user, further improving the protective effect of the life jacket 100; any first gas pipe 111 is provided with a first one-way valve 112, and any second gas pipe 121 is provided with a second one-way valve 122. The first one-way valve 112 and the second one-way valve 122 have opposite valve opening directions. The first one-way valve 112 and the second one-way valve 122 strictly limit the flow direction of oxygen and carbon dioxide (such as Figure 2The first gas storage bin 110 and the second gas storage bin 120 are arranged to ensure that the gas inside the life jacket 100 basically maintains a dynamic balance; and due to the setting of the one-way valve, each of the first gas storage bin 110 and the second gas storage bin 120 remains relatively independent. Even if part of the first gas storage bin 110 and the second gas storage bin 120 is damaged, the first gas storage bin 110 and the second gas storage bin 120 of the other parts can also maintain a normal protective effect for a period of time, thereby increasing the user's chance of survival; the protective helmet 200 is provided with an inflatable protection component for protecting the head and neck and a rescue reminder component 300 for sending a distress message. The inflatable protection component is connected to the first gas storage bin 110 and the second gas storage bin 120. After the first gas storage bin 110 transmits oxygen to the protective helmet 200, it is absorbed by the user; the carbon dioxide exhaled by the user is transported to the second gas storage bin 120 through the inflatable protection component, The gas dynamic balance inside the life jacket 100 can be basically achieved, ensuring that the protective effect of the life jacket 100 will not be affected; and the second gas storage bin 120 storing carbon dioxide is arranged inside the first gas storage bin 110, so even if the first gas storage bin 110 is hit and damaged, it can ensure that the second gas storage bin 120 can continue to provide protection, the design is unique and the protective effect is good; the top of the protective helmet 200 is provided with a solar charging component 400, and the solar charging component 400 is connected to the rescue reminder component 300, and the energy in the sunlight obtained by the solar component is converted into the energy of the rescue reminder component 300, so that the rescue reminder component 300 sends a distress signal, and the rescue personnel can quickly locate the user's position through the distress signal, reduce the difficulty of rescue, realize fast and accurate rescue operations, and further improve the user's survival probability. Therefore, the embodiment of the present invention has the beneficial effects of good protection effect, reduced rescue difficulty and improved patient survival probability.

[0038] It should be noted that the life jacket 100 can be made into a one-piece type with the protective helmet 200 for easy carrying; or according to the needs of use, the life jacket 100 and the protective helmet 200 can be made into a separate type, and the connection method of the life jacket 100 and the helmet is a detachable connection method, which enhances the applicability of this product and meets various usage needs.

[0039] It should be noted that, in some other embodiments, the second gas storage bin 120 may not be arranged inside the first gas storage bin 110. Figure 3 As shown; the first air storage bin 110 and the second air storage bin 120 can be arranged side by side, so that the expansion volume of the life jacket 100 is increased, and the protection effect of the life jacket 100 can also be improved.

[0040] In some embodiments of the present invention, Figure 1The above-mentioned inflation assembly includes a first compressed oxygen tank 131 and a first inflation valve 132 , one end of the first inflation valve 132 is connected to the first compressed oxygen tank 131 , and the other end is connected to the first gas storage bin 110 . In a general emergency situation, after the user puts on the life jacket 100, the first inflation valve 132 is opened to allow the oxygen in the first compressed oxygen tank 131 to be quickly filled into the multiple first gas storage bins 110. The volume of the first gas storage bins 110 expands after being filled with oxygen, thereby expanding the overall volume of the life jacket 100. When the user is drowning, the life jacket 100 can provide sufficient buoyancy to prevent the user from drowning; the user can float on the water surface and wait for rescue or can rescue himself; when facing mudslides or floods, the life jacket 100 is used in conjunction with the protective helmet 200. The life jacket 100 can provide buoyancy to the user while reducing the impact force received by the user, thereby reducing the damage to the patient; the protective helmet 200 can protect the user's head and neck, prevent the user from suffering fatal impact injuries, and increase the user's survival rate in floods or mudslides. In addition, when wearing a helmet, the user can breathe the oxygen in the first gas storage chamber 110 of the life jacket 100, and then transport the exhaled carbon dioxide to the second gas storage chamber 120 for storage, so that the gas in the life jacket 100 basically maintains a dynamic balance, thereby extending the user's survival time and improving the chance of survival.

[0041] It should be noted that, in some other embodiments, the first inflation valve 132 may preferably be a quick inflation valve (existing technology), so that the first compressed oxygen tank 131 can deliver oxygen faster, and can provide safety protection for the user more quickly when dealing with emergencies.

[0042] In some embodiments of the present invention, the life jacket 100 is provided with a wearing assembly 500, so that the life jacket 100 is more securely worn and prevents the life jacket 100 from falling off in dangerous situations. The wearing assembly 500 includes a buckle or a zipper. Figure 1 As shown, after the user puts on the life jacket 100, the buckle is fastened to make it very convenient to put on, and it also makes the life jacket 100 more secure to wear. A zipper can also be selected. After the user puts on the life jacket 100, the zipper is used to tighten the life jacket 100 so that the patient's body parts are completely covered, which has a better protection effect.

[0043] It should be noted that the life jacket 100 can be a vest-type life jacket 100, which is convenient for the user to wear quickly. In some other embodiments, a long-sleeved life jacket 100 can be selected according to specific use requirements.

[0044] In some embodiments of the present invention, reference Figure 4The above-mentioned inflatable protection component includes a mask pop-up bin 600, an airbag pop-up bin 620, a ventilating tube 630, a second compressed oxygen tank 640 and a second inflating valve 650; the mask pop-up bin 600 is provided with an airbag opening 621 of the breathing mask 620 and an inflatable top block 610, the airbag opening 621 of the breathing mask 620 abuts against the top block 610, after the top block 610 is formed, the top block 610 pushes the airbag opening 621 of the breathing mask 620 out of the mask pop-up bin 600 and close to the user's mouth and nose; the airbag opening 621 is provided in the airbag pop-up bin 620, and the airbag opening 621 is provided with an inflatable protective airbag 6 20. After the airbag is inflated and formed, it pops out from the airbag opening 621, protecting the user's head and neck while squeezing the user's head forward, so that the user's mouth and nose fit with the airbag opening 621 of the breathing mask 620; the second compressed oxygen tank 640 is arranged inside the protective helmet 200 to avoid direct expansion with external objects and affecting normal use; the air inlet of the second inflation valve 650 is connected to the second compressed oxygen tank 640, and the air outlet of the second inflation valve 650 is connected to the top block 610 and the protective airbag 620 respectively through the ventilation pipe 630, so that oxygen is quickly filled into the top block 610 and the protective airbag 620 through the trachea. During actual use, the second inflation valve 650 is opened, so that the oxygen in the second compressed oxygen tank 640 is quickly transmitted to the compressed top block 610 and the compressed protective airbag 620 through the ventilation pipe 630. Since the volume of the top block 610 is smaller than that of the protective airbag 620, the top block 610 can be expanded and formed quickly, and then the top block 610 expands the mask pop-up bin 600, and pushes the airbag opening 621 of the breathing mask 620 out of the bin, so that the airbag opening 621 of the breathing mask 620 is close to the user's mouth and nose; then the protective airbag 620 is inflated and expanded, and pops out from the airbag opening 621 into the internal space of the protective helmet 200, thereby squeezing the user's head and forcing the user's head to tilt forward slightly, so that the user's mouth and nose are also fitted with the airbag opening 621 of the breathing mask 620, so as to achieve oxygen inhalation and carbon dioxide discharge.

[0045] In some embodiments of the present invention, the mask ejection chamber 600 includes an expansion slot 630 to protect the airbag 620, and the top block 610 is located at the bottom of the expansion slot 630 to protect the airbag 620. Figure 5At this time, the top block 610 is in a compressed state, and the airbag opening 621 of the breathing mask 620 is also in the mask ejection chamber 600; both ends of the expansion groove 630 protecting the airbag 620 are provided with slide grooves 631, and the airbag opening 621 of the breathing mask 620 is provided with a slider 621 slidably connected with the slide groove 631. As the volume of the top block 610 expands, the slider 621 slides with the slide groove 631, and the airbag opening 621 of the breathing mask 620 is gradually pushed upward by the expanded top block 610 to protect the airbag 620, thereby realizing the functions of supplying oxygen to the user and discharging carbon dioxide. The design is reasonable and has good practicality.

[0046] In some embodiments of the present invention, the airbag port 621 of the breathing mask 620 is provided with an inlet check valve 622 for oxygen inhalation through the nose and an outlet check valve 623 for carbon dioxide exhalation through the mouth. Figure 6 The inlet check valve 622 is connected to the first gas storage bin 110 through the vent pipe 630, and the outlet check valve 623 is connected to the second gas storage bin 120 through the air pipe. The position of the air inlet check valve 622 fits the user's nose. The user exhales through the nose, so that the air inlet check valve 622 is opened, and the oxygen in the first air storage chamber 110 in the life jacket 100 is inhaled into the user's nose through the air inlet check valve 622, thereby completing the oxygen supply; the air outlet check valve 623 is close to the user's mouth, and through the exhalation effect of the mouth, the air outlet check valve 623 is opened, and carbon dioxide flows into the second air storage chamber 120 for storage and collection; during the inhalation and exhalation, the exchange of oxygen and carbon dioxide is achieved; while the oxygen in the first air storage chamber 110 is reduced, the second air storage chamber 120 is supplemented with carbon dioxide, so that the gas in the life jacket 100 basically maintains a dynamic balance; the use time of the life jacket 100 can be extended to a certain extent, thereby increasing the user's chance of survival in a dangerous situation and providing the rescue team with more sufficient rescue time.

[0047] It should be noted that, in some other embodiments, the ventilation tube 630 is a compressed air tube. The compressed air tube has a foldable structure, such as Fig. 9 As shown; when stretched, the foldable structure of the compressed air tube can be stretched out, so that the length of the compressed air tube becomes longer, the use is more flexible, and the practicality is stronger; at the same time, the compressed air tube 630 only needs to occupy a smaller space. When the user's head is deflected, the protective helmet 200 pulls the compressed air tube 630 to stretch, thereby avoiding the insufficient length of the air tube 630 affecting the flexibility of use of this product.

[0048] In some embodiments of the present invention, the above-mentioned inflatable protection component further includes a water-blocking airbag 660, which is connected to the second inflatable valve 650 through the ventilation pipe 630, and the water-blocking airbag 660 is arranged around the lower end of the protective helmet 200, and the specific reference is made to Figure 4 and Figure 7 The water-blocking airbag 660 is annular in shape as a whole. After the second inflation valve 650 is opened, the oxygen in the second compressed oxygen tank 640 is quickly filled into the water-blocking airbag 660, so that it is quickly formed. The inflated and formed water-blocking airbag 660 fills the gap between the bottom of the protective helmet 200 and the outside world, so that a relatively closed environment is formed inside the protective helmet 200. In the event of a flood or a mud-rock flow, it can block water or foreign objects from the outside world to prevent them from entering the protective helmet 200 and causing damage to the head and neck of the user. The design is reasonable and can further improve the protectiveness of the protective helmet 200.

[0049] In some embodiments of the present invention, the protective helmet 200 is further provided with goggles 700, which are rotatably connected to the protective helmet 200, and a sealing strip 710 is provided at the contour edge of the goggles 700. Figure 7 and Figure 8 After the user puts on the protective helmet 200, the goggles 700 can be turned down to block foreign objects or muddy water outside the protective helmet 200, thereby protecting the patient's eyes and face and further improving the protectiveness of the protective helmet 200; a sealing strip 710 is provided at the contour edge of the goggles 700. When the goggles 700 are turned down and fit with the protective helmet 200, the sealing strip 710 fills the small gap between the goggles 700 and the protective helmet 200, which can further enhance the airtightness of the protective helmet 200 and prevent external water from penetrating into the protective helmet 200; at the same time, the loss of oxygen and carbon dioxide can be reduced, so that the dynamic gas balance inside the life jacket 100 can be maintained for a longer time, thereby extending the protection time and protection effect of the life jacket 100.

[0050] It should be noted that, in some other embodiments, air outlets may be further provided around the goggles 700; when the goggles 700 fog up and block the user's vision, the air outlets may be opened to allow the fog on the outer surface of the goggles 700 to dissipate and restore the user's vision.

[0051] In some embodiments of the present invention, the solar charging component 400 includes a solar panel 410 and a small battery 420 electrically connected to each other, and the small battery 420 is electrically connected to the rescue reminder component 300. The solar panel 410 converts the absorbed light energy into electrical energy and stores it in the small battery 420 to provide energy for the rescue reminder component 300. Figure 4 and Figure 7As shown. The rescue reminder component 300 includes GPS, Bluetooth or a light-emitting element; through the auxiliary positioning function of GPS, the rescue team can quickly locate the user's position, which can help the rescue team determine the approximate preliminary range; the positioning function of Bluetooth allows the rescue team to further narrow the search and rescue range after determining the search and rescue range, ensuring rapid rescue; the light-emitting element can provide visual reminders for the rescue team members at night or in a dark environment, making it convenient for the rescue team members to determine the specific location of the user; the light-emitting element can specifically use an LED light-emitting lamp, which has a long service life and low power consumption, and can be used for a longer time at night or in a dark environment.

[0052] In some embodiments of the present invention, the protective helmet 200 is an ABS plastic helmet. ABS plastic has good impact resistance, structural strength and corrosion resistance; good impact resistance and structural strength can improve the protective performance of the protective helmet 200, so that the wearer's head is well protected and prevents the head from suffering fatal injuries; good corrosion resistance can make the protective helmet 200 have better tolerance and be suitable for a variety of dangerous environments.

[0053] Working principle of the life preserver: after the user puts on the life jacket 100 and the protective helmet 200, when a dangerous situation occurs, the first inflation valve 132 is opened, so that the oxygen in the first compressed oxygen tank 131 is quickly filled into the multiple first gas storage bins 110. After the first gas storage bins 110 are filled with oxygen, the volume expands, thereby expanding the overall volume of the life jacket 100 to provide buffer protection or buoyancy support for the user; at the same time, the second inflation valve 650 is opened, so that the oxygen in the second compressed oxygen tank 640 is quickly transmitted to the compressed top block 610 and the compressed protective airbag 620 through the ventilation pipe 630. As the volume of the top block 610 expands, the slider 621 slides with the slide groove 631, and the airbag opening 621 of the breathing mask 620 is gradually pushed upward by the expanded top block 610 to push the expansion groove 630 protective airbag 620, thereby popping out the mask pop-up bin 600 and approaching the user's mouth and nose; then the protective airbag 620 is inflated and expanded. The air is ejected from the airbag opening 621 into the inner space of the protective helmet 200, thereby squeezing the user's head and forcing the user's head to tilt forward slightly. The user's mouth and nose are therefore fitted with the airbag opening 621 of the breathing mask 620, so that oxygen is inhaled and carbon dioxide is discharged; the user exhales through the nose, so that the air inlet check valve 622 provided on the airbag opening 621 of the breathing mask 620 is opened, and the oxygen in the first air storage bin 110 in the life jacket 100 is inhaled into the nose of the user through the air inlet check valve 622, thereby completing the oxygen supply; the air outlet check valve 623 is close to the user's mouth, and the air outlet check valve 623 is opened through the exhalation effect of the mouth, and carbon dioxide flows into the second air storage bin 120 for storage and collection; in one exhalation and one breath, the exchange of oxygen and carbon dioxide is realized; while the oxygen in the first air storage bin 110 is reduced, the second air storage bin 120 is supplemented with carbon dioxide at the same time, so that the gas in the life jacket 100 basically maintains a dynamic balance.

[0054] In summary, the embodiment of the present invention provides a life preserver, comprising a life jacket 100 and a protective helmet 200 connected to each other; the life jacket 100 and the protective helmet 200 can simultaneously protect the upper body and the head of the human body; the life jacket 100 and the protective helmet 200 are connected through a ventilating pipe 630 to realize gas exchange between the life jacket 100 and the helmet, so that the gas inside the life jacket 100 can basically maintain dynamic balance; an inflation protection component and a rescue reminder component 300 are arranged in the protective helmet 200; the inflation protection component comprises a mask pop-up chamber 600, an air bag pop-up chamber 620, a ventilating pipe 630, a second compressed oxygen tank 640 and a second inflation valve 650, and by opening the second inflation valve 650, the air bag port of the breathing mask 620 arranged in the mask pop-up chamber 600 is opened. The protective airbag 621 and the protective airbag 620 arranged in the airbag ejection chamber 620 are ejected successively, and the protective airbag 620 provides protection for the user's head and forces the user's mouth and nose to fit with the airbag opening 621 of the breathing mask 620; an inlet check valve 622 and an outlet check valve 623 are arranged on the airbag opening 621 of the breathing mask 620, and the inlet check valve 622 allows the oxygen in the first air storage chamber 110 to be inhaled by the user's nose, and the outlet check valve 623 allows the carbon dioxide exhaled from the user's mouth to flow into the second air storage chamber 120, which can basically achieve the dynamic balance of gas inside the life jacket 100, prolong the protection effect and buoyancy effect provided by the life jacket 100, and improve the patient's survival rate; in addition, the second air storage chamber 120 is arranged in the first air storage chamber 110 0, so even if the first gas storage bin 110 is damaged by impact, it can ensure that the second gas storage bin 120 can continue to provide protection, the design is unique and the protection effect is good; any one of the first gas delivery pipes 111 is provided with a first one-way valve 112, and any one of the second gas delivery pipes 121 is provided with a second one-way valve 122. The valve opening directions of the first one-way valve 112 and the second one-way valve 122 are opposite. The first one-way valve 112 and the second one-way valve 122 strictly limit the flow direction of oxygen and carbon dioxide, so that oxygen can only flow from the first gas storage bin 110 to the protective helmet 200, and carbon dioxide can only flow from the helmet to the second gas storage bin 120, ensuring that the gas inside the life jacket 100 basically maintains a dynamic balance; and due to the setting of the one-way valve, each first gas delivery pipe 111 is provided with a first one-way valve 112, and the second one-way valve 122 is provided with a second one-way valve 122. The first gas storage bin 110 and the second gas storage bin 120 are kept relatively independent. Even if part of the first gas storage bin 110 and the second gas storage bin 120 is damaged, the other parts of the first gas storage bin 110 and the second gas storage bin 120 can also maintain a normal protective effect for a period of time, thereby increasing the user's chance of survival. A solar charging component 400 is provided on the top of the protective helmet 200. The solar charging component 400 is connected to the rescue reminder component 300. The energy in the sunlight is obtained by the solar component and converted into energy for the rescue reminder component 300, so that the rescue reminder component 300 sends out a distress signal. Rescuers can quickly locate the user's position through the distress signal, thereby reducing the difficulty of rescue, realizing fast and accurate rescue operations, and further increasing the user's chance of survival.
