[0024] A heat preservation pad 1, which is used to isolate the human body from the ground;

[0025] A rubber sleeve 2, the bottom of which is fixedly connected to the top of the thermal insulation pad 1;

[0028] The bottom of the liner 10, the buffer air column 11 and the down lining 12 are fixedly connected to the top of the thermal insulation pad 1, and the buffer air column 11 is located in the interlayer between the liner 10 and the down lining 12, and is arranged along the interlayer filling.

[0029] The inflation device 7 includes an air bag 14 , the inner wall of the air bag 14 is fixedly connected to a sealing tube 15 , the inner wall of the sealing tube 15 is slidably connected to a piston 16 , the inner wall of the piston 16 is slidably connected to a one-way valve 17 , and an air intake pipe 18 is arranged outside the one-way valve 17 .

[0030] The bottom end of the air intake pipe 18 is rotatably connected to the inner wall of the sealing tube 15 . The inner wall of the sealing tube 15 is provided with an exhaust hole 19 . The exhaust hole 19 is located inside the air bag 14 , and the air intake pipe 18 is located outside the air bag 14 .

[0031] The inner wall of the air bag 14 is fixedly connected with a bent pipe 20 , the outer wall of the bent pipe 20 is fixedly connected with an exhaust pipe 23 , the outer wall of the exhaust pipe 23 is fixedly connected with a cross pipe 22 , and the outer wall of the cross pipe 22 is fixedly connected with an intake pipe 21 .

[0032] The air bag 14, the bent pipe 20, the exhaust pipe 23, the cross pipe 22 and the intake pipe 21 are connected to each other. The intake pipe 21 passes through the down lining 12 and extends to the inside of the down lining 12. The cross pipe 22 is located in the gap between the rubber sleeve 2 and the inner liner 10. The outer wall of the intake pipe 21 is fixedly connected to the inner walls of the rubber sleeve 2, the inner liner 10 and the down lining 12.

[0033] Working principle:

[0034] When the device is in use, untie the strap 6 from the backpack, take off the sleeping bag, and lay the sleeping bag flat so that the thermal pad 1 is in contact with the ground. Then manually pull the inflation device 7 to inject air into the interlayer between the rubber sleeve 2, the liner 10 and the down lining 12. The sleeping bag is inflated and opened. Bind the strap 6 to a tree or a fixed frame outside to prevent the sleeping bag from shaking. Then open the zipper 4 and enter the sleeping bag from the opening. Since the zipper adopts a double-head design, the zipper is pulled inside the sleeping bag, and the head is located at the bottom of the ventilation window 5. The ventilation window 5 adopts an acrylic panel, which can take into account ventilation while also allowing for lighting, making it easy to observe the external environment.

[0035] When manually pulling out the inflator 7, one hand holds the exposed part of the sealing tube 15, and the other hand holds the exposed part of the piston 16, and the piston 16 is continuously and rapidly pulled out. In the process of the piston 16 being pressed into the sealing tube 15, the air on the left side of the one-way valve 17 is compressed, and the reaction force of the compressed air forces the one-way valve 17 to slide rightward relative to the piston 16. Since the side of the one-way valve 17 close to the exhaust hole 19 is much larger than the side close to the suction pipe 18, in this process, the large end of the one-way valve 17 fits with the piston 16, blocking the through hole opened in the piston 16, and the air is continuously compressed and injected into the interior of the air bag 14 from the exhaust hole 19. 9 and the interior of the air intake pipe 18 adopt a structure similar to the one-way valve 17. When the piston 16 approaches the exhaust hole 19, the valves inside the air intake pipe 18 and the exhaust hole 19 are opened, and the one-way valve 17 is closed. When the piston 16 moves away from the exhaust hole 19, the valves inside the air intake pipe 18 and the exhaust hole 19 are closed, and the one-way valve 17 is opened. The air on the right side of the one-way valve 17 is compressed to the space on its left side through the through hole, and the cycle is repeated. During this process, the air enters the air bag 14, and then flows along the curved pipe 20 and through the cross pipe 22 into the space between the rubber sleeve 2 and the inner liner 10. With the auxiliary support of the buffer air column 11, the entire sleeping bag is propped up.

[0036] When encountering a situation similar to an avalanche, the buzzer 13 is pressed to send a distress signal. The vertically installed buffer 11 air column can provide a certain support in the vertical space. The person is trapped inside the down lining 12, and the air inside the down lining 12 is gradually consumed until the air inside the sleeping bag gradually decreases. The buzzer 13 alarms, and the person pulls out the plug of the air inlet pipe 21 extending into one side of the sleeping bag. The air inside the air bag 14 and the interlayer between the rubber sleeve 1 and the liner 10 enters the sleeping bag through the cross pipe 22, providing additional oxygen supply to the inside personnel, prolonging the survival time to a certain extent, and increasing the probability of self-rescue and being rescued.

[0037] When wading is required, the inflated sleeping bag is placed on the water surface, the zipper 4 is opened, and items or people can be placed inside the sleeping bag. Since the sleeping bag adopts a multi-layer inflatable structure and the inflatable device 7 is installed on both sides, when in use, the suction end of the suction pipe 18 can be turned upward to prevent water from flowing into the air bag 14. The entire sleeping bag can float steadily on the water surface, which can effectively extend the chance of survival of people outdoors.

[0038] When the sleeping bag needs to be stored, the plug inside the exhaust pipe 23 is pulled out, the air flows out from the inside of the sleeping bag, and the whole sleeping bag is rolled up.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
