[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-9This invention provides a portable respiratory function training device, including a horizontal tube 1, a vertical tube 5 fixedly connected and connected to the bottom surface of the horizontal tube 1, a flexible tube 3 detachably connected to the end of the horizontal tube 1, a base plate 6 fixedly connected and connected to the bottom of the vertical tube 5, a first transparent cylinder 8 fixedly connected and connected to the top surface of the base plate 6 away from the vertical tube 5, a pipe opened inside the base plate 6, the vertical tube 5 and the first transparent cylinder 8 connected through the pipe, a connecting pipe 7 fixedly connected and connected to the top of the first transparent cylinder 8, the top of the connecting pipe 7 fixedly connected and connected to the horizontal tube 1, a first rotating component installed inside the horizontal tube 1, a second rotating component installed inside the vertical tube 5, an adjustment mechanism symmetrically installed on the first transparent cylinder 8, a drive component connected to the adjustment mechanism, the drive component located outside the first transparent cylinder 8, a protective box 9 provided outside the drive component, the protective box 9 fixedly connected to the outer wall of the first transparent cylinder 8, a second transparent cylinder 10 detachably connected to the side of the first transparent cylinder 8 away from the protective box 9, the structure of the second transparent cylinder 10 being consistent with the first transparent cylinder 8.

[0031] The horizontal tube 1 and vertical tube 5 correspond to inhalation and exhalation exercises, respectively. During exhalation, the mouth holds the flexible tube 3 and blows air inward. The air opens the second rotating component and enters the vertical tube 5, then flows into the pipe in the base plate, and finally into the first transparent cylinder 8. The adjustment mechanism in the first transparent cylinder 8 is squeezed, allowing observation of the internal situation and facilitating adaptive adjustments based on actual conditions. The pressure can be adjusted by driving the adjustment mechanism through a drive component to accommodate different individuals. Inhalation and exhalation are performed at the same angles. Furthermore, a second transparent cylinder 10 can be installed to increase the internal space and achieve better exercise results. This invention integrates inhalation and exhalation exercises, is simple and convenient to operate, and its parts are easily disassembled for easy carrying in a carrying case. It is compact and portable, highly adjustable, and has low manufacturing costs, making it suitable for a wider range of people.

[0032] The scheme is further optimized. The adjustment mechanism includes a fixed block 26 fixed to the inner wall of the first transparent cylinder 8. A connecting rod 24 is slidably connected inside the fixed block 26. A sliding block 21 is fixed to the top of the connecting rod 24. A fixed plate 22 is fixed to the inner wall of the first transparent cylinder 8. The sliding block 21 contacts the top surface of the fixed plate 22. An annular plate and an adjustment plate 23 are fixed to the outer side of the connecting rod 24. A spring 25 is fixed between the annular plate and the adjustment plate 23. The spring 25 is sleeved on the outer side of the connecting rod 24. An adjustment component is fixed to the bottom surface of the adjustment plate 23. The adjustment component is connected to the drive component. During exhalation exercise, gas enters the bottom of the first transparent cylinder 8 through the vertical pipe 5. The gas pushes the sliding block 21 to move upward. The sliding block 21 drives the connecting rod 24 to move upward. At this time, the spring 25 is compressed. After the exhalation action stops, the sliding block 21 is reset by the spring 25 for the next use. The adjustment component can move the adjustment plate 23 downward, thereby reducing the relative distance between the adjustment plate 23 and the annular plate, thereby increasing the pressure of the spring 25 and enhancing the exercise effect.

[0033] The scheme is further optimized. The adjustment component includes a lead screw 31 that is symmetrically fixed to the bottom surface of the adjustment plate 23. A sleeve 27 is slidably connected to the bottom of the lead screw 31. The bottom of the sleeve 27 is fixed to the fixed block 26. A first spur gear 28 is threaded to the outside of the lead screw 31. The first spur gear 28 is rotatably connected to the top surface of the sleeve 27. The first spur gear 28 meshes with a second spur gear 33. A vertical shaft is fixed to the center of the second spur gear 33. The bottom of the vertical shaft is rotatably connected to the fixed block 26. A second bevel gear 32 is fixed to the outside of the vertical shaft. The second bevel gear 32 is located above the second spur gear 33. The second bevel gear 32 meshes with a first bevel gear 30. A connecting shaft 29 is fixed to the center of the first bevel gear 30. One end of the connecting shaft 29 is rotatably connected to the inner wall of the first transparent cylinder 8. The other end of the connecting shaft 29 passes through the first transparent cylinder 8 and is connected to the drive component for transmission. The drive assembly drives the connecting shaft 29 to rotate, the connecting shaft 29 drives the first bevel gear 30 to rotate, the first bevel gear 30 drives the second bevel gear 32 to rotate, the second bevel gear 32 drives the second spur gear 33 to rotate, the second spur gear 33 drives the first spur gear 28 to rotate, and the rotation of the first spur gear 28 causes the lead screw 31 to move vertically, thereby changing the position of the adjusting plate 23 and achieving the purpose of adjusting the pressure.

[0034] The scheme is further optimized. The drive component includes a limiting cylinder 36 fixed to the inner wall of the protective box 9. One end of a sliding rod 37 is slidably connected inside the limiting cylinder 36. The other end of the sliding rod 37 extends out of the protective box 9 and is fixed to a knob 38. The knob 38 contacts the outer wall of the protective box 9. A fourth spur gear 43 is fixed to the sliding rod 37. Two connecting shafts 29 extend into the protective box 9 and are fixed to third spur gears 39. The two third spur gears 39 are staggered. The fourth spur gear 43 is detachably connected to the two third spur gears 39 respectively. Pushing the knob 38 inward moves the sliding rod 37 inward, causing the fourth spur gear 43 to mesh with the lower third spur gear 39, which can adjust the position of the lower adjustment plate 23 inside the first transparent cylinder 8. Conversely, pulling the knob 38 outward makes the fourth spur gear mesh with the upper third spur gear 39, which can adjust the upper adjustment plate 23 inside the first transparent cylinder 8. The operation is simple and convenient. The limiting cylinder 36 limits the sliding rod 37 to prevent slippage.

[0035] The design is further optimized by symmetrically creating limiting grooves 34 within the fixed block 26. A limiting block 35 is slidably connected within the limiting groove 34, and the limiting block 35 is fixedly connected to the connecting rod 24. The limiting block 35 can only slide within the limiting groove 34, and the length of the limiting groove 34 determines the movement distance of the connecting rod 24, thus facilitating observation.

[0036] In a further optimized design, the first rotating component includes a first central shaft 16 fixedly connected to the inner wall of the horizontal tube 1. The first central shaft 16 is rotatably connected to a first partition 17, which is adapted to fit the inner wall of the horizontal tube 1. During inhalation, the first partition 17 rotates around the first central shaft 16, opening the airway of the horizontal tube 1 to facilitate inhalation exercises.

[0037] In a further optimized design, the second rotating assembly includes a second central shaft 18 fixedly connected to the inner wall of the vertical tube 5. A second partition 19 is rotatably connected to the second central shaft 18 and is adapted to fit the inner wall of the vertical tube 5. A torsion spring 20 is sleeved on the outer side of the second central shaft 18, with one end of the torsion spring 20 fixedly connected to the inner wall of the vertical tube 5 and the other end fixedly connected to the second partition 19. During exhalation, the second partition 19 rotates around the second central shaft 18, opening the airway of the vertical tube 5 to facilitate exhalation exercises. At this time, the first partition 17 is closed, obstructing the airway of the horizontal tube 1. The torsion spring 20 facilitates the repositioning of the second partition 19.

[0038] In a further optimized design, a first ventilation tube 11 is symmetrically fixed and connected to the side of the first transparent tube 8 away from the protective box 9. A second ventilation tube 13 is detachably connected to the end of the first ventilation tube 11 away from the first transparent tube 8 via a threaded sleeve 12. The end of the second ventilation tube 13 away from the threaded sleeve 12 is fixed and connected to the second transparent tube 10. A third ventilation tube 14 is symmetrically fixed and connected to the side of the second transparent tube 10 away from the second ventilation tube 13. A plug 15 is threadedly connected to the end of the third ventilation tube 14. Increasing the number of second transparent tubes 10 can increase the volume of air during exhalation or inhalation, thus improving the training effect. The plug 15 on the second transparent tube 10 can be removed to install a third transparent tube; the specific number can vary depending on the individual to achieve the desired training effect.

[0039] In a further optimized design, a threaded tube 42 is fixedly connected to the end of the first vent pipe 11 furthest from the first transparent cylinder 8. An embedded tube 40 is fixedly connected to the side of the threaded tube 42 closest to the threaded sleeve 12. The embedded tube 40 extends into the second vent pipe 13, with the inner diameter of the second vent pipe 13 being the same as the outer diameter of the embedded tube 40. A retaining ring 41 is fixedly connected to the outer side of the second vent pipe 13. The threaded sleeve 12 is threadedly connected to the threaded tube 42. The threaded sleeve 12 and the threaded tube 42 facilitate installation and disassembly, making them easy to carry and expanding their applicability. The retaining ring 41 prevents the threaded sleeve 12 from slipping, improving installation efficiency.

[0040] The design is further optimized by attaching a connector 2 to the threaded end of the horizontal tube 1. The connector 2 is fixedly connected to and communicates with the hose 3. The end of the hose 3 away from the connector 2 is fixedly connected to and communicates with a mouthpiece 4. The connector 2 is detachably connected to the horizontal tube 1, which facilitates cleaning of the storage box. The mouthpiece 4 is used for blowing and inhaling, making it more convenient to use.
