Description

Technical Field

[0001] The invention relates to the technical field of hypoxia training, in particular to an adjustable hypoxia training device for plateau hypoxia training. Background Art

[0002] The low oxygen environment of the plateau will directly affect the health of people who move to the plateau, causing a series of problems such as high incidence of acute altitude sickness and reduced ability to continue working. According to statistics, more than 35.6% of people will experience acute altitude sickness of varying degrees during the period of rapid migration from the plain to the plateau, manifested as headache, anorexia, vomiting, fatigue, dizziness, insomnia and other symptoms. If not properly treated, some patients may develop high-altitude pulmonary edema or high-altitude cerebral edema, which will endanger their lives. Plateau medical research shows that slow step-by-step intermittent hypoxia compound exercise can significantly improve the body's cardiopulmonary function and improve labor capacity.

[0003] During use, the existing hypoxic training cabin adopts overall ventilation. If the hypoxic training cabin is large, the oxygen content at the top may be relatively low and the dirty air at the bottom may not be discharged in time, which may not meet the special needs of different height areas in the cabin well. At the same time, in terms of ventilation uniformity, overall ventilation may make the air quality in areas close to the air inlet and outlet better, while the air renewal is relatively slow in places far away from these areas. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable hypoxic training device for plateau hypoxia training, comprising a cabin, an observation window is fixedly connected to the outside of the cabin, a movable door is arranged at the front end of the cabin, an air inlet is arranged at the bottom of the rear end of the cabin, and an exhaust fan is fixedly connected to the top of the cabin;

[0005] The shell is fixedly mounted in the inner cavity of the cabin, and an intermediate plate is fixedly connected to the gap between the shell and the cabin;

[0006] An air supply assembly, which is fixedly installed inside the cabin and is located on a side away from the movable door;

[0007] The shell includes a frame, which is fixedly connected to the interior of the cabin, an exhaust hole is opened in the middle of the top of the frame, and an air inlet is opened at the bottom of the frame, and the air inlet is arranged in a trapezoidal shape;

[0008] Preferably, the air supply assembly includes an oxygen concentrator, which is fixedly installed inside the cabin, and an air pipe is fixedly connected to one side of the oxygen concentrator close to the air inlet, and a connecting hole is opened on the outside of the air pipe. A V-shaped block is arranged on the outside of the air pipe, and the concentration of oxygen discharged by the oxygen concentrator is adjusted according to actual needs. When the oxygen concentrator is working, air enters the oxygen concentrator through the air inlet, and the mixed gas enters the inside of the air pipe and is then discharged from the connecting hole, so that the gas enters the inside of the frame through the air inlet, so that the inside of the cabin is in a low oxygen situation, and when the ventilation volume inside the air pipe increases, the limit ring inside the air pipe is forced to expand outward, and extrusion is generated between the limit ring and the cylinder, and the cylinder drives the V-shaped block It deforms toward the side away from the gas pipe, so that the gas is discharged in an inclined direction. At this time, when the lower layer of gas enters obliquely upward, it will generate upward power, making it easier for the lower layer of gas to mix with the middle and upper layers of gas, avoiding oxygen accumulation in the lower layer, making the oxygen concentration in the cabin more evenly distributed in the vertical direction, reducing the dead corners of exhaust gas in the cabin, and allowing exhaust gas to be discharged more smoothly out of the cabin. A limit ring is fixedly connected to the inner side of the gas pipe near the connecting hole, and the limit ring is elastic. A circular hole is opened on the side of the V-shaped block, and the V-shaped block is elastic. A cylinder is fixedly connected to the side of the V-shaped block near the gas pipe, and the cylinder is slidably connected to the gas pipe, and the V-shaped block is located inside the air inlet.

[0009] Preferably, there are multiple observation windows, which are evenly arranged on the outside of the cabin. An air outlet is opened at the rear end of the cabin, and the air outlet is symmetrically arranged with the air inlet as the center. A guide plate is fixedly connected to the top of the shell.

[0010] The side of the air inlet hole close to the middle plate is the short side of the trapezoid. There are multiple connecting holes, and the multiple connecting holes are evenly arranged on the air pipe. The connecting holes and the air inlet holes are located on the same straight line. The cylinder passes through the air pipe and extends to the inside. The end of the cylinder away from the V-shaped block contacts the outer side of the limit ring.

[0011] Preferably, a guide block is fixedly connected to the inner wall of the frame, the guide block is located at the top side corner of the frame, a connecting pipe is fixedly connected to the outer side of the frame, the connecting pipe is fixedly connected to the observation window, a through hole is opened in the middle of the inner side of the frame, and the through holes are arranged in three rows in a stepped manner. When the oxygen generator is working, air enters the oxygen generator through the air inlet, and the mixed gas enters the inside of the round rod. The gas in the round rod enters the inside of the frame through the through hole. Part of the air will flow to the upper layer through the through hole in the upper layer, providing fresh air for the upper area and replacing the original air in the upper layer. The dirty air in the upper layer can be discharged to the frame through the exhaust hole at the top, and the other part of the air will be discharged to the frame through the exhaust hole at the top. The air will flow to the lower layer through the through holes in the lower layer, and air replacement will also be carried out. The design of the through hole structure is conducive to forming a good airflow organization, which promotes the air to flow and diffuse more evenly at different height levels, avoiding ventilation dead corners, thereby effectively improving the overall ventilation efficiency, allowing the indoor and outdoor air to be fully exchanged and maintaining the freshness of the air. There are multiple middle plates, and the multiple middle plates divide the interval between the frame and the cabin into five parts. The two middle plates are located in the middle of the upper and lower through holes, and a spring plate is fixedly connected to the side of the frame close to the through hole, and a block is fixedly connected to the inner wall of the middle plate close to the side of the spring plate, and the block is located inside the through hole.

[0012] Preferably, a fixed pipe is fixedly connected to the outside of the oxygen concentrator, the fixed pipe is fixedly connected to the top corner of the frame, the fixed pipe is communicated with the guide block, and a round rod is fixedly connected to the outside of the oxygen concentrator. By arranging the round rod, the fixed pipe and the air pipe, the upper, middle and lower layers inside the frame are stratified and ventilated. The three-layer ventilation can form a good vertical and horizontal air circulation. The air in the lower layer is fully mixed with the air in the middle layer during the rising process, and the air in the middle layer is exchanged with the air in the upper layer. This circulation method helps to evenly distribute fresh air to all corners of the frame and avoid air stagnation areas, thereby optimizing the air quality in the entire cabin. The round rod is located in the middle of the fixed pipe and the air pipe, and the round rod is located on the outside of the through hole between the two middle plates.

When the movable door is closed, the slider moves inside the sliding groove toward the entrance of the cabin body, and the slider drives the movable plate to move through the clamping plate. At this time, the support plate moves with the movable plate inside the inclined groove, and the gap between the inclined groove and the sliding groove becomes smaller, so that the support plate applies a force to the movable plate through the supporting plate. At this time, the movable plate is forced to slide inside the fixed frame, and when the slider moves to the other end of the sliding groove, the outer ring groove of the fixed frame is adapted to the entrance of the cabin body. Under the support of the support plate, the fixed frame and the cabin body are tightly fitted, so that the tightness of the movable door is good, preventing outside air from entering Entering, resulting in an increase in cabin pressure, which makes it impossible to accurately simulate the plateau environment, but a well-sealed cabin door can effectively prevent this from happening, ensuring that the cabin pressure is stable at the required low pressure level, so that activities such as training or treatment can be carried out in the expected environment, a moving plate is fixedly connected to the outside of the splint, a fixed frame is slidably connected to the outside of the moving plate, a round window is fixedly connected to the outside of the fixed frame, a ring groove is provided at the front end of the fixed frame, an inclined groove is provided on the side of the fixed block away from the sliding groove, a support plate is slidably connected to the inner wall of the inclined groove, a support plate is fixedly connected to the side of the moving plate away from the splint, the support plate is fixedly connected to the support plate on the side away from the moving plate, a convex ring is fixedly connected to the side of the splint away from the moving plate, a limit frame is fixedly connected to the side of the fixed frame close to the convex ring, and the limit frame and the convex ring are adapted to each other.

[0014] The present invention provides an adjustable hypoxia training device for plateau hypoxia training. It has the following beneficial effects:

[0015] 1. The adjustable hypoxic training equipment for plateau hypoxic training can form good vertical and horizontal air circulation through three-layer ventilation. The air in the lower layer is fully mixed with the air in the middle layer during the rising process, and the air in the middle layer is exchanged with the air in the upper layer. This circulation method helps to evenly distribute fresh air to all corners of the frame, avoiding air stagnation areas, thereby optimizing the air quality in the entire cabin.

[0016] 2. The adjustable hypoxic training equipment for plateau hypoxic training will generate upward power, making it easier for the lower layer of gas to mix with the middle and upper layers of gas, avoiding oxygen accumulation in the lower layer, making the oxygen concentration in the cabin more evenly distributed in the vertical direction, reducing dead corners of exhaust gas in the cabin, and allowing exhaust gas to be discharged more smoothly out of the cabin.

[0017] 3. The adjustable hypoxic training equipment for plateau hypoxic training is conducive to the formation of good airflow organization through the design of the through-hole structure, which promotes the air to flow and diffuse more evenly at different height levels, avoids ventilation dead corners, and effectively improves the overall ventilation efficiency, so that indoor and outdoor air can be fully exchanged and the air can be kept fresh.

[0018] 4. The adjustable hypoxia training equipment for plateau hypoxia training fits tightly with the cabin body through a fixed frame, so that the movable door has good airtightness, preventing outside air from entering, causing the air pressure in the cabin to rise, and failing to accurately simulate the plateau environment. A well-sealed cabin door can effectively prevent this from happening, ensuring that the air pressure in the cabin is stable at the required low pressure level, so that activities such as training or treatment can be carried out in the expected environment.

[0038] The air supply assembly 8 includes an oxygen concentrator 81, which is fixedly installed inside the cabin 1. An air pipe 84 is fixedly connected to the side of the oxygen concentrator 81 near the air inlet 25. A connecting hole 85 is provided on the outside of the air pipe 84. A V-shaped block 86 is provided on the outside of the air pipe 84. The concentration of oxygen discharged by the oxygen concentrator 81 is adjusted according to actual needs. When the oxygen concentrator 81 is working, air enters the oxygen concentrator 81 through the air inlet 7, and the mixed gas enters the inside of the air pipe 84 and is then discharged from the connecting hole 85, so that the gas enters the inside of the frame 21 through the air inlet 25, so that the inside of the cabin 1 is in a low oxygen situation. When the ventilation volume inside the air pipe 84 increases, the limit ring 89 inside the air pipe 84 is forced to expand outward, and extrusion is generated between the limit ring 89 and the cylinder 88. The cylinder 8 8 drives the V-shaped block 86 to deform toward the side away from the gas pipe 84, so that the gas is discharged in an inclined direction. At this time, when the lower layer of gas enters obliquely upward, it will generate upward power, making it easier for the lower layer of gas to mix with the middle and upper layers of gas, avoiding oxygen accumulation in the lower layer, making the oxygen concentration in the cabin more evenly distributed in the vertical direction, reducing the dead corners of exhaust gas in the cabin, and allowing the exhaust gas to be discharged more smoothly out of the cabin. The inner side of the gas pipe 84 near the connecting hole 85 is fixedly connected to a limit ring 89, and the limit ring 89 is elastic. A circular hole 87 is opened on the side of the V-shaped block 86, and the V-shaped block 86 is elastic. A cylinder 88 is fixedly connected to the side of the V-shaped block 86 near the gas pipe 84, and the cylinder 88 is slidably connected to the gas pipe 84. The V-shaped block 86 is located inside the air inlet 25.

[0039] The second embodiment is based on the first embodiment. Figures 6 to 9 As shown, there are multiple observation windows 4, which are evenly arranged on the outside of the cabin 1. An air outlet 6 is opened at the rear end of the cabin 1, and the air outlet 6 is symmetrically arranged with the air inlet 7 as the center. A guide plate 10 is fixedly connected to the top of the shell 2.

There are multiple connecting holes 85, and the multiple connecting holes 85 are evenly arranged on the air pipe 84. The connecting holes 85 and the air inlet hole 25 are located on the same straight line. The cylinder 88 passes through the air pipe 84 and extends to the inside. The end of the cylinder 88 away from the V-shaped block 86 contacts the outer side of the limit ring 89.

[0041] The inner wall of the frame 21 is fixedly connected with a guide block 23, and the guide block 23 is located at the top side corner of the frame 21. The outer side of the frame 21 is fixedly connected with a connecting pipe 26, and the connecting pipe 26 is fixedly connected to the observation window 4. A through hole 24 is opened in the middle of the inner side of the frame 21, and the through holes 24 are arranged in three rows in a stepped manner. When the oxygen generator 81 is working, air enters the oxygen generator 81 through the air inlet 7, and the mixed gas enters the inside of the round rod 83. The gas in the round rod 83 enters the inside of the frame 21 through the through hole 24. Part of the air will flow to the upper layer through the through hole 24 on the upper layer, providing fresh air for the upper area and replacing the original air on the upper layer. The dirty air on the upper layer can be discharged to the frame 21 through the exhaust hole 22 on the top. Part of the air will flow to the lower layer through the lower through holes 24, and air replacement will also be carried out. The design of the through hole 24 structure is conducive to forming a good airflow organization, which promotes the air to flow and diffuse more evenly at different height levels, avoiding ventilation dead corners, thereby effectively improving the overall ventilation efficiency, allowing the indoor and outdoor air to be fully exchanged and maintaining the freshness of the air. There are multiple middle plates 9, and the multiple middle plates 9 divide the interval between the frame 21 and the cabin 1 into five parts. Two middle plates 9 are located in the middle of the upper and lower through holes 24. The side of the frame 21 close to the through hole 24 is fixedly connected with a spring plate 28, and the inner wall of the middle plate 9 close to the side of the spring plate 28 is fixedly connected with a stopper 27, and the stopper 27 is located inside the through hole 24.

The fixed pipe 82 is communicated with the guide block 23. A round rod 83 is fixedly connected to the outside of the oxygen concentrator 81. By arranging the round rod 83, the fixed pipe 82 and the air pipe 84, the upper, middle and lower layers inside the frame 21 are stratified and ventilated. The three-layer ventilation can form a good vertical and horizontal air circulation. The air in the lower layer is fully mixed with the air in the middle layer during the rising process, and the air in the middle layer is exchanged with the air in the upper layer. This circulation method helps to evenly distribute fresh air to all corners of the frame 21, avoid air stagnation areas, and thus optimize the air quality in the entire cabin. The round rod 83 is located in the middle of the fixed pipe 82 and the air pipe 84, and the round rod 83 is located on the outside of the through hole 24 between the two middle plates 9.

[0043] The third embodiment is based on the first and second embodiments. Figures 10 to 13As shown, the movable door 3 includes a fixed block 31, which is fixedly connected to the inner wall of the cabin 1, a slide groove 32 is provided at the front end of the fixed block 31, a slider 313 is slidably connected to the inner wall of the slide groove 32, a square hole 314 is provided at the top of the slider 313, and a clamping plate 310 is slidably connected to the inner wall of the square hole 314. When the movable door 3 is closed, the slider 313 moves inside the slide groove 32 toward the entrance of the cabin 1, and the slider 313 drives the movable plate 39 to move through the clamping plate 310. At this time, the support plate 3 As the moving plate 39 moves inside the inclined groove 36, the gap between the inclined groove 36 and the slide groove 32 becomes smaller, so that the support plate 37 exerts a force on the moving plate 39 through the support plate 38. At this time, the moving plate 39 is forced to slide inside the fixed frame 33. When the slider 313 moves to the other end of the slide groove 32, the outer annular groove 34 of the fixed frame 33 is adapted to the inlet of the cabin 1. Under the support of the support plate 37, the fixed frame 33 is closely fitted with the cabin 1, so that the tightness of the moving door 3 is good. , preventing outside air from entering, causing the cabin pressure to rise, and failing to accurately simulate the plateau environment, and a well-sealed cabin door can effectively prevent this from happening, ensuring that the cabin pressure is stable at the required low pressure level, so that activities such as training or treatment can be carried out in the expected environment, a moving plate 39 is fixedly connected to the outer side of the splint 310, a fixed frame 33 is slidably connected to the outer side of the moving plate 39, a round window 35 is fixedly connected to the outer side of the fixed frame 33, a ring groove 34 is provided at the front end of the fixed frame 33, an inclined groove 36 is provided on the side of the fixed block 31 away from the slide groove 32, a support plate 37 is slidably connected to the inner wall of the inclined groove 36, a support plate 38 is fixedly connected to the side of the moving plate 39 away from the splint 310, and a side of the support plate 38 away from the moving plate 39 is fixedly connected to the support plate 37, a side of the splint 310 away from the moving plate 39 is fixedly connected to a convex ring 311, and a side of the fixed frame 33 close to the convex ring 311 is fixedly connected to a limited position frame 312, and the limited position frame 312 and the convex ring 311 are adapted.

[0044] When in use, the concentration of oxygen discharged by the oxygen concentrator 81 is adjusted according to actual needs. When the oxygen concentrator 81 is working, air enters the oxygen concentrator 81 through the air inlet 7, and the mixed gas enters the interior of the air pipe 84, and then is discharged from the connecting hole 85, so that the gas enters the interior of the frame 21 through the air inlet 25, so that the interior of the cabin 1 is in a low oxygen situation. When the ventilation volume inside the air pipe 84 increases, the limit ring 89 inside the air pipe 84 is forced to expand outward, and compression is generated between the limit ring 89 and the cylinder 88. The cylinder 88 drives the V-shaped block 86 to deform toward the side away from the air pipe 84, so that the gas is discharged in an inclined direction. At this time, when the lower layer of gas enters obliquely upward, an upward force is generated, making the lower layer of gas easier to mix with the middle and upper layers of gas, avoiding oxygen accumulation in the lower layer, making the oxygen concentration in the cabin more evenly distributed in the vertical direction, reducing the dead corners of exhaust gas in the cabin, and allowing the exhaust gas to be discharged out of the cabin more smoothly.

[0045] When the movable door 3 is closed, the slider 313 moves inside the slide groove 32 toward the entrance of the cabin body 1, and the slider 313 drives the movable plate 39 to move through the clamping plate 310. At this time, the support plate 37 moves inside the inclined groove 36 with the movable plate 39, and the gap between the inclined groove 36 and the slide groove 32 becomes smaller, so that the support plate 37 applies force to the movable plate 39 through the support plate 38. At this time, the movable plate 39 slides inside the fixed frame 33 under the force. When the slider 313 moves to the other end of the slide groove 32, the outer annular groove 34 of the fixed frame 33 is adapted to the entrance of the cabin body 1. Under the support of the support plate 37, the fixed frame 33 and the cabin body 1 are tightly fitted, so that the tightness of the movable door 3 is good.
