[0002] In mines, tunnels, and other dangerous environments such as fires, self-isolated compressed oxygen self-rescuers are essential equipment for protecting people's lives. Their core function is to isolate users from toxic and harmful gases while providing them with clean, breathable oxygen.
[0003] Traditional compressed oxygen self-rescue devices release high-pressure oxygen rapidly when the valve is opened, which can easily cause the user to choke and feel uncomfortable, thus hindering timely self-rescue. Utility Model Content
[0004] The purpose of this invention is to provide a mine compressed oxygen self-rescue device with a compressed air bladder. By setting up a compressed air bladder for buffering, the high-pressure oxygen first fills the compressed air bladder after the oxygen tank is opened before being delivered to the worker's nose. The one-way valve has a small valve opening threshold, which makes the oxygen delivery smoother and avoids choking the worker. This solves the problem that in traditional compressed oxygen self-rescue devices, when the valve is opened in an emergency, the high-pressure oxygen is ejected too quickly, which can easily cause choking and discomfort to the user, affecting timely self-rescue.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine compressed oxygen self-rescue device with a compressed air bag, comprising an equipment compartment, an oxygen tank, and a base plate. A connecting pipe is fixedly connected to one side of the oxygen tank, and a compressed air bag is fixedly connected to the end of the connecting pipe away from the oxygen tank. A one-way valve is fixedly connected to the top of the compressed air bag, an exhaust pipe is fixedly connected to the top of the one-way valve, and a face mask is fixedly connected to the top of the exhaust pipe. A bite-shaped opening is fixedly installed on the inner wall of the face mask.
[0006] A limiting frame is fixedly connected to the inner wall of the equipment compartment, and a buffer pad is fixedly connected to the bottom of the limiting frame to cushion the compressed airbag.
[0007] Preferably, connecting plates are fixedly connected to both sides of the outer wall of the equipment compartment, and bolts are threadedly connected to both sides of the connecting plates. A support platform is fixedly connected to the top of the base plate, and the bottom of the oxygen tank is fixedly connected to the top of the support platform. Threaded holes are opened at the four corners of the top of the base plate, and the tail end of the bolt is threaded into the inner wall of the threaded hole of the base plate. The top of the base plate fits against the bottom of the equipment compartment and the connecting plate, and the four corners of the bottom of the base plate are fixedly connected to the support legs.
[0008] Preferably, a top cover is rotatably connected to the top side of the equipment compartment via a hinge, a buckle plate is rotatably connected to the side of the top cover via a hinge, and a fixing buckle is fixedly connected to one side of the outer wall of the equipment compartment, with the buckle plate and the fixing buckle slidably engaging.
[0009] Preferably, a breathable pad and a carrying strap are fixedly connected to one side of the equipment compartment, with the carrying strap located on both sides of the breathable pad.
[0010] Preferably, grips are fixedly connected to both sides of the outer wall of the equipment compartment.
[0011] Preferably, a touch panel is fixedly connected to one side of the outer wall of the equipment compartment. The touch panel is electrically connected to the oxygen tank via a transmission line, and the touch panel has a built-in wireless data transmission module.
[0012] Preferably, a protective tube and a switching button are fixedly connected to one side of the outer wall of the equipment compartment. The switching button is located inside the protective tube and is electrically connected to the oxygen tank via a transmission line. A sealing cap is threaded onto the side of the protective tube away from the equipment compartment.
[0013] Preferably, a gas filling valve is fixedly installed on the top of the oxygen tank.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting up a compression bladder for buffering, the high-pressure oxygen first fills the compression bladder after the oxygen tank is opened before being delivered to the worker's nose. The one-way valve has a small valve opening threshold, which makes the oxygen delivery smoother and avoids choking the worker. This solves the problem that in traditional compressed oxygen self-rescue devices, when the valve is opened in an emergency, the high-pressure oxygen is ejected too quickly, which can easily cause choking and discomfort to the user, affecting timely self-rescue.
[0016] 2. By setting up a compression airbag, a limiting frame, and a buffer pad, the compression airbag is initially compressed. After oxygen enters the compression airbag, it gradually expands until the top of the compression airbag hits the bottom of the buffer pad. The limiting frame and buffer pad limit and protect the compression airbag, causing it to stop expanding to a certain extent, preventing it from bursting. They also limit the deformation range of the compression airbag, shortening the expansion time and accelerating the oxygen delivery speed, so that workers can breathe oxygen faster and more smoothly.

A mask 7 is fixedly connected to the top of the exhaust pipe 6, and a bite 8 is fixedly installed on the inner wall of the mask 7.
[0025] A limit frame 9 is fixedly connected to the inner wall of the equipment compartment 1, and a buffer pad 10 is fixedly connected to the bottom of the limit frame 9 to buffer the compressed air bag 4.
[0026] Connecting plates 11 are fixedly connected to both sides of the outer wall of the equipment compartment 1. Bolts 12 are threadedly connected to both sides of the connecting plates 11. A support platform 14 is fixedly connected to the top of the bottom plate 13. The bottom of the oxygen tank 2 is fixedly connected to the top of the support platform 14. Threaded holes are opened at the four corners of the top of the bottom plate 13. The tail end of the bolt 12 is threaded into the inner wall of the threaded hole of the bottom plate 13. The top of the bottom plate 13 fits against the bottom of the equipment compartment 1 and the connecting plate 11. Support legs 15 are fixedly connected to the four corners of the bottom of the bottom of the bottom plate 13. The connecting plate 11 and the bottom plate 13 are connected by bolts 12. The equipment compartment 1 can be disassembled and removed from the outside of the oxygen tank 2 and the compressed air bag 4 for easy maintenance.
[0027] The top of the equipment compartment 1 is connected to a top cover 21 via a hinge. The side of the top cover 21 is connected to a buckle plate 22 via a hinge. A fixing buckle 23 is fixedly connected to one side of the outer wall of the equipment compartment 1. The buckle plate 22 and the fixing buckle 23 slide and engage. The top cover 21 can be flipped open for easy access to the mask 7. When not in use, the top cover 21 is locked by the buckle plate 22, the fixing buckle 23, and another lock to prevent unauthorized personnel from using it. During the standby period, the lock is removed for easy and quick access.
[0028] A breathable pad 24 and a shoulder strap 25 are fixedly connected to one side of the equipment compartment 1. The shoulder strap 25 is located on both sides of the breathable pad 24. The equipment compartment 1 is carried by carrying it on the back through the shoulder strap 25. The breathable pad 24 improves the comfort when carrying it.
[0029] Both sides of the outer wall of the equipment compartment 1 are fixedly connected to handles 26, which facilitates lifting the equipment compartment 1 and lifting the equipment compartment 1 when disassembling the equipment compartment 1 and the base plate 13 to expose the oxygen tank 2 and the compressed air bag 4 for maintenance.
[0030] A touch panel 16 is fixedly connected to one side of the outer wall of the equipment compartment 1. The touch panel 16 is electrically connected to the oxygen tank 2 through a transmission line. The touch panel 16 displays the air pressure and oxygen quantity in the oxygen tank 2 in real time.
[0031] A protective tube 17 and a switching button 19 are fixedly connected to one side of the outer wall of the equipment compartment 1. The switching button 19 is located inside the protective tube 17. The switching button 19 is electrically connected to the oxygen tank 2 through a transmission line. A sealing cap 18 is threaded onto the side of the protective tube 17 away from the equipment compartment 1. The sealing cap 18 prevents accidental activation of the switching button 19. By unscrewing the sealing cap 18 and pressing the switching button 19, the oxygen tank 2 can be quickly started to release oxygen.
[0032] The top of the oxygen tank 2 is fixedly equipped with a gas filling valve 20. The touch panel 16 has a built-in wireless data transmission module to transmit the operating status data of the oxygen tank 2 to the management personnel. If the oxygen in the oxygen tank 2 is insufficient, it can be replenished in time through the gas filling valve 20.
[0033] The working principle of this utility model:
[0034] Workers carry the equipment compartment 1 on their backs using shoulder straps 25. In the event of an accident in the mine, the top cover 21 is flipped open, and the sealing cover 18 is twisted off. Then, the switching button 19 is pressed to activate the oxygen tank 2 and release oxygen. The oxygen is discharged into the compression bladder 4 through the connecting pipe 3. The compression bladder 4 is initially compressed. After the oxygen enters the compression bladder 4, it gradually expands until the top of the compression bladder 4 hits the bottom of the buffer pad 10. The limiting frame 9 and the buffer pad 10 limit and protect the compression bladder 4, stopping its expansion to a certain extent to prevent it from bursting. They also limit the deformation of the compression bladder, shortening the expansion time and accelerating the oxygen delivery speed, allowing workers to inhale oxygen more quickly. During the inflation of the compression bladder 4, the worker puts on the mask 7 and bites down on the bite 8. After the top of the compression bladder 4 contacts the bottom of the buffer pad 10, the compression bladder 4 stops deforming. The positive pressure inside the compression bladder 4 opens the one-way valve 5, and oxygen is transmitted to the worker's mouth through the exhaust pipe 6 and the bite 8 for timely oxygen replenishment. By setting the compression bladder 4 for buffering, the high-pressure oxygen fills the compression bladder 4 first after the oxygen tank 2 is opened before being delivered to the worker's mouth. The valve opening threshold of the one-way valve 5 is relatively small, making the oxygen delivery smoother and avoiding choking on the worker. This solves the problem that when traditional compressed oxygen self-rescue devices are used in emergencies, the high-pressure oxygen is ejected too quickly when the valve is opened, which can easily cause choking and discomfort to the user, affecting timely self-rescue.
[0035] Meanwhile, the oxygen tank 2 can be controlled via the touch panel 16 to adjust the gas delivery valve of the oxygen tank 2 and change the gas delivery speed to further improve comfort. After the oxygen in the oxygen tank 2 is emptied, the gas delivery valve of the oxygen tank 2 is closed, and the compression bag 4 is pressed down to empty the remaining oxygen in the compression bag 4 to avoid waste and restore the compression bag 4 to its initial state for easy refilling and next use.
