Description

Technical Field

[0001] This invention relates to the field of respiratory training equipment technology, specifically a multi-level adjustable respiratory training mask for high-altitude low-oxygen environment care. Background Technology

[0002] A breathing training mask is a device used to strengthen respiratory muscles, regulate breathing rhythm, and improve the body's gas exchange efficiency. It is widely used in respiratory rehabilitation, physical enhancement, and special environment adaptation training. In high-altitude, low-oxygen environments, the air is thin and the oxygen partial pressure is low. Different groups of people have significantly different hypoxia tolerance and respiratory muscle training needs. Untrained people are prone to problems such as shortness of breath and rhythm disorders. Therefore, breathing training masks need to have multi-level adjustable functions to adapt to the full-stage training needs from low-load adaptation to high-load enhancement by adjusting breathing resistance and oxygen supply rhythm, helping users gradually improve breathing efficiency and body tolerance in low-oxygen environments.

[0003] Commonly used high-altitude hypoxia breathing training masks mostly use manual valves or pad stacking to adjust resistance. Some masks achieve oxygen supply rhythm control through a simple through-hole switching structure. However, in use, the rhythm adjustment structure and resistance adjustment structure of these masks are independent of each other, and the breathing rate can only be adjusted by the user's subjective judgment, making it difficult to form a standardized breathing rhythm guidance. Summary of the Invention

[0009] Preferably, the outer wall of the limiting ring is rotatably connected to the inner wall of the fixed bracket, and the lower surface of the guide post is rotatably connected to the upper surface of the guide plate.

[0010] Preferably, a guide ring two is fixedly connected to the upper surface of the guide ring one, a limit ring two is fixedly connected to the upper surface of the guide ring two, a gear ring two is fixedly connected to the outer wall of the limit ring two, a fixing post two is fixedly connected to the lower surface of the gear ring two, a pinion two is meshed with the tooth end of the gear ring two, a large gear two is meshed with the tooth end of the pinion two, a guide post two is fixedly connected to the inner wall of the large gear two, a coincident post is fixedly connected to the inner wall of the pinion two, and a guide bracket is rotatably connected to the outer wall of the coincident post.

[0011] Preferably, the inner wall of the fixed bracket two is fixedly connected to a guide rail, the outer wall of the guide rail is slidably connected to a limit bracket, the inner bottom wall of the limit bracket is fixedly connected to a spring two, the upper surface of the spring two is fixedly connected to a limit post three, the outer wall of the limit post three is fixedly connected to a slider, the upper surface of the limit post three is fixedly connected to a guide post three, and the outer wall of the limit bracket is fixedly connected to an adjustable perforated plate.

[0012] Preferably, the outer wall of the second guide ring is rotatably connected to the inner wall of the second fixed bracket, and the inner wall of the guide bracket is rotatably connected to the outer wall of the second limiting ring.

[0014] Preferably, the outer wall of the adjustable perforated plate is slidably connected to the inner wall of the fixed bracket two, and the outer wall of the limiting bracket is slidably connected to the inner wall of the fixed bracket two.

[0015] Working principle: The motor drives the transmission shaft to rotate, which in turn drives the large gear to rotate. The large gear then drives the guide post to rotate, which in turn drives the small gear to rotate. The small gear further drives the positioning post to rotate, which in turn drives the limiting plate to rotate. This, in turn, drives the limiting plate to rotate the guide ring, which in turn drives the limiting ring to rotate. This causes the rotating holes of the guide ring to periodically overlap, adjusting the breathing rhythm of the mask body during high-altitude low-oxygen breathing training. This not only guides the user's breathing frequency but also prevents the waste of oxygen during exhalation.

[0016] By rotating the limiting post one outward, the fixing post one rotates, the fixing post one rotates, the limiting post two rotates, the limiting post two rotates, the spring one rotates, and the spring one rotates, which in turn rotates the threaded post. Thus, the threaded post rotates and disengages from the oxygen tube, completing the disassembly of the mask body and achieving the effect of convenient assembly and disassembly of the mask body.

[0017] The rotation of guide ring one drives the rotation of guide ring two, which in turn drives the rotation of limit ring two, which in turn drives the rotation of gear ring two, which in turn drives the rotation of fixed column two, which in turn drives the rotation of pinion gear two, which in turn drives the rotation of gear two, which in turn drives the rotation of gear two, which in turn drives the rotation of guide column two, which in turn drives the rotation of overlapping column, which in turn drives the rotation of guide bracket. The rotation of overlapping column provides visual breathing prompts to trainees undergoing high-altitude hypoxia breathing training, preventing rapid or slow breathing, and achieving the effect of visually guiding trainees to adjust their breathing rate.

[0018] By pulling down the slider, the limiting post three moves, which in turn compresses the spring two. This compression then moves the guide post three, which further disengages from the fixed bracket two and moves the limiting bracket. Consequently, the limiting bracket moves the adjustable orifice plate to adjust pipes of different diameters for training high-altitude hypoxic individuals, achieving the effect of adapting to the load requirements of different training stages.

[0019] This invention provides a multi-level adjustable breathing training mask for use in high-altitude, low-oxygen environments. It offers the following beneficial effects: 1. This invention uses a starting motor to drive a transmission shaft to rotate, which in turn drives a large gear to rotate. This large gear then drives a guide post to rotate, which in turn drives a small gear to rotate. The small gear further drives a positioning post to rotate, which in turn drives a limiting plate to rotate. This, in turn, drives a guide ring to rotate, which in turn drives a limiting ring to rotate. This causes the rotating holes of the guide ring to periodically overlap, thus adjusting the breathing rhythm of the mask body during high-altitude low-oxygen breathing training. This not only guides the user's breathing frequency but also avoids wasting oxygen during exhalation.

[0020] 2. This invention uses a starting motor to drive the transmission shaft to rotate, which in turn drives the large gear one to rotate, simultaneously driving the small gear two to rotate. The small gear two drives the large gear two to rotate, which in turn drives the guide column two to rotate. The guide column two drives the overlapping column to rotate, which in turn drives the guide bracket to rotate. The rotation of the overlapping column provides visual breathing prompts to trainees undergoing high-altitude hypoxia breathing training, preventing rapid or slow breathing, and achieving the effect of visually guiding trainees to adjust their breathing rate.

[0021] 3. The present invention rotates the limiting post one outward to drive the fixing post one to rotate, the fixing post one to drive the limiting post two to rotate, and then the limiting post two to drive the spring one to rotate. The spring one further drives the threaded post to rotate, so that the threaded post rotates and disengages from the oxygen tube, thus completing the disassembly of the mask body, achieving the effect of convenient assembly and disassembly of the mask body.

[0022] 4. This invention moves the limiting column three by pulling down the slider, which in turn compresses the spring two. The compression of the spring two then moves the guide column three, which further disengages from the fixed bracket two and moves the limiting bracket. This allows the limiting bracket to move the adjustable orifice plate to adjust pipes of different diameters for training people with low oxygen levels at high altitudes, thus achieving the effect of adapting to the load requirements of different training stages.

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a multi-level adjustable breathing training mask for high-altitude hypoxic environment care, comprising a fixed bracket 1, an oxygen tank 2 fixedly connected to the inner wall of the fixed bracket 1, a guide plate 3 fixedly installed at the output end of the oxygen tank 2, a fixed bracket 4 fixedly connected to the upper surface of the guide plate 3, a motor 5 fixedly installed on the fixed bracket 4, a transmission shaft 6 fixedly installed at the output end of the motor 5, a large gear 7 fixedly connected to the outer wall of the transmission shaft 6, a guide post 8 fixedly connected to the lower surface of the large gear 7, a small gear 9 meshing with the tooth end of the guide post 8, a gear ring 10 meshing with the tooth end of the small gear 9, a positioning post 11 fixedly connected to the inner wall of the small gear 9, a limit plate 12 rotatably connected to the outer wall of the positioning post 11, a guide ring 13 fixedly connected to the outer wall of the limit plate 12, a limit ring 14 fixedly connected to the outer wall of the guide ring 13, and a disassembly assembly provided on the inner wall of the fixed bracket 4.

[0027] Specifically, the starting motor 5 drives the transmission shaft 6 to rotate, which in turn drives the large gear 7 to rotate. The fixed bracket 4 supports and fixes the motor 5, ensuring that the motor 5 does not wear during operation. Simultaneously, the fixed bracket 4 restricts and guides the transmission shaft 6, ensuring that the position of the transmission shaft 6 does not shift when driven by the motor 5. Furthermore, the transmission shaft 6 fixes the large gear 7, preventing it from falling off during rotation. This rotation of the large gear 7 drives the guide post 8 to rotate, which in turn drives the small gear 9 to rotate, which in turn drives the positioning post 11 to rotate. The guide plate 3 supports and restricts the guide post 8, ensuring that it does not fall off during rotation. Simultaneously, the gear ring 10 meshes with the small gear 9, ensuring that the position of the small gear 9 does not shift during rotation. Wheel 9 fixes the positioning post 11, ensuring its position remains unchanged during rotation. This rotation of the positioning post 11 causes the limiting plate 12 to rotate, which in turn causes the guide ring 13 to rotate, which in turn causes the limiting ring 14 to rotate. The guide ring 13 fixes the limiting plate 12, preventing it from falling off during rotation. Meanwhile, the fixing bracket 4 restricts and guides the guide ring 13, ensuring its position does not shift during rotation. The fixing bracket 4 also supports and guides the limiting ring 14, preventing its position from shifting during rotation. This rotation of the guide ring 13 aligns the through-hole with the face mask body 16, regulating the breathing rhythm during high-altitude low-oxygen breathing training. This not only guides the user's breathing frequency but also prevents oxygen waste during exhalation.

[0028] Please see the appendix Figure 3 - Appendix Figure 10 The disassembly assembly includes an oxygen tube 15, the outer wall of which is set on the inner wall of the fixed bracket 2 4. The outer wall of the oxygen tube 15 is attached to the mask body 16. The outer wall of the mask body 16 is fixedly connected to a bandage 17. The outer wall of the mask body 16 is rotatably connected to a limit post 18. The outer wall of the limit post 18 is fixedly connected to a fixed post 19. The outer wall of the fixed post 19 is fixedly connected to a limit post 20. The outer wall of the limit post 20 is fixedly connected to a spring 21. The outer wall of the limit post 20 is fixedly connected to a threaded post 22.

[0029] Specifically, by rotating the first limiting post 18 outward, the first fixing post 19 is driven to rotate, which in turn drives the second limiting post 20 to rotate. The mask body 16 restricts the first limiting post 18, ensuring its position does not change during rotation. Simultaneously, the mask body 16 supports and guides the first fixing post 19, ensuring its position does not shift during rotation. Furthermore, the mask body 16 supports and restricts the second limiting post 20, preventing it from falling off during rotation. This allows the second limiting post 20 to rotate... The rotating mechanism drives the spring 21 to rotate, which in turn drives the threaded post 22 to rotate, causing the threaded post 22 to rotate out of the oxygen tube 15. The mask body 16 restricts the spring 21, ensuring that its position does not change during rotation. At the same time, the oxygen tube 15 supports and guides the threaded post 22, preventing it from shifting its position during rotation. This allows the threaded post 22 to rotate out of the oxygen tube 15, completing the disassembly of the mask body 16 and achieving the effect of convenient assembly and disassembly of the mask body 16.

[0030] Please see the appendix Figure 1 - Appendix Figure 7 The outer wall of the gear ring 10 is fixedly connected to the inner wall of the fixed bracket 2 4, and the outer wall of the guide post 8 is rotatably connected to the inner wall of the fixed bracket 2 4.

[0031] Specifically, the gear ring 10 is fixed by the second fixing bracket 4 to ensure that the position of the gear ring 10 does not change. At the same time, the second fixing bracket 4 restricts and guides the guide post 8 to ensure that the position of the guide post 8 does not shift when it rotates.

[0032] Please see the appendix Figure 1 - Appendix Figure 7 The outer wall of the drive shaft 6 is rotatably connected to the inner wall of the fixed bracket 2 4, and the outer wall of the guide ring 13 is rotatably connected to the inner wall of the fixed bracket 2 4.

[0033] Specifically, the drive shaft 6 is restricted and guided by the fixed bracket 2 4 to ensure that the position of the drive shaft 6 will not shift when it is driven to rotate by the motor 5, and the fixed bracket 2 4 restricts the guide ring 13 so that the position of the guide ring 13 will not change when it rotates.

[0034] Please see the appendix Figure 1 - Appendix Figure 10 The outer wall of the limiting ring 14 is rotatably connected to the inner wall of the fixed bracket 4, and the lower surface of the guide post 8 is rotatably connected to the upper surface of the guide plate 3.

[0035] Specifically, the limiting ring 14 is supported and guided by the fixed bracket 2 4 to ensure that the position of the limiting ring 14 will not fall off when it rotates. At the same time, the guide plate 3 supports and restricts the guide post 8 so that the position of the guide post 8 will not change when it rotates.

[0036] Please see the appendix Figure 1 - Appendix Figure 7 A guide ring 23 is fixedly connected to the upper surface of guide ring 13. A limit ring 24 is fixedly connected to the upper surface of guide ring 23. A gear ring 25 is fixedly connected to the outer wall of limit ring 24. A fixing post 26 is fixedly connected to the lower surface of gear ring 25. A pinion 27 is meshed with the tooth end of gear ring 25. A large gear 28 is meshed with the tooth end of pinion 27. A guide post 29 is fixedly connected to the inner wall of large gear 28. A coincident post 30 is fixedly connected to the inner wall of pinion 27. A guide bracket 31 is rotatably connected to the outer wall of coincident post 30.

[0037] Specifically, the rotation of guide ring 13 drives the rotation of guide ring 23, which in turn drives the rotation of limit ring 24. Fixed bracket 24 restricts and guides guide ring 13, ensuring that the position of limit ring 14 does not shift during rotation. Fixed bracket 24 also supports and guides guide ring 23, ensuring that its position does not change during rotation. Furthermore, fixed bracket 24 supports and guides limit ring 24, preventing it from falling off during rotation. This rotation of limit ring 24 drives the rotation of gear ring 25, which in turn drives the rotation of fixed post 26, which in turn drives the rotation of pinion 27. Limit ring 24 fixes and restricts gear ring 25, ensuring that its position does not change during rotation. Simultaneously, limit ring 24 supports and restricts fixed post 26, preventing its position from changing during rotation. When the gear ring 25 falls, it meshes with the pinion 27, ensuring that the pinion 27 does not shift its position during rotation. The rotation of the pinion 27 then drives the rotation of the large gear 28, which in turn drives the rotation of the guide post 29, which in turn drives the rotation of the overlapping post 30. The engagement of the pinion 27 with the large gear 28 ensures that the large gear 28 does not shift its position during rotation. Simultaneously, the fixing post 26 supports and guides the guide post 29, ensuring that its position does not change during rotation. The pinion 27 also fixes the overlapping post 30, preventing it from falling during rotation. This causes the overlapping post 30 to rotate, driving the guide bracket 31 to rotate. The rotation of the overlapping post 30 provides visual breathing prompts to the trainee undergoing high-altitude hypoxia breathing training, preventing rapid or slow breathing and achieving the effect of visually guiding the trainee to adjust their breathing rate.

[0038] Please see the appendix Figure 1 - Appendix Figure 8 The inner wall of the fixed bracket 2 4 is fixedly connected to the guide rail 32, the outer wall of the guide rail 32 is slidably connected to the limit bracket 33, the inner bottom wall of the limit bracket 33 is fixedly connected to the spring 2 34, the upper surface of the spring 2 34 is fixedly connected to the limit post 35, the outer wall of the limit post 35 is fixedly connected to the slider 36, the upper surface of the limit post 35 is fixedly connected to the guide post 37, and the outer wall of the limit bracket 33 is fixedly connected to the adjustable perforated plate 38.

[0039] Specifically, by pulling down the slider 36, the limiting post 35 moves, which in turn compresses the spring 34. The limiting bracket 33 restricts and guides the slider 36, ensuring its position does not shift during movement. The limiting bracket 33 also guides and restricts the limiting post 35, preventing its position from changing during movement. Furthermore, the limiting bracket 33 fixes and supports the spring 34, preventing it from falling out when compressed. This compression causes the guide post 37 to move, disengaging it from the fixed bracket 4. The internal drive limit bracket 33 moves, which in turn moves the adjustable orifice plate 38. The fixed bracket 2 4 restricts and guides the guide column 37 to ensure that the position of the guide column 37 does not shift when it moves. At the same time, the guide rail 32 supports and guides the limit bracket 33 to ensure that the position of the limit bracket 33 does not change when it moves. The fixed bracket 2 4 supports and restricts the adjustable orifice plate 38 to prevent it from falling when it moves. Thus, the adjustable orifice plate 38 can be adjusted to move different diameter pipes to train people with low oxygen levels at high altitudes, achieving the effect of adapting to the load requirements of different training stages.
