Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of respiratory training, more particularly, the present application relates to a diaphragmatic breathing training device for lung function training. BACKGROUND

[0002] The strength of lung function is directly related to the oxygen supply and metabolic efficiency of the human body. For patients with chronic obstructive pulmonary disease, postoperative rehabilitation groups and long-term lack of exercise groups, scientific lung function training is crucial. Diaphragmatic breathing, as a training method that can effectively exercise the diaphragm and increase lung capacity, is widely used in clinical rehabilitation and daily health care. However, there are still many problems to be solved in the implementation process of current diaphragmatic breathing training. In actual training, patients often lack professional guidance and intuitive feedback, making it difficult to accurately master the essentials of diaphragmatic breathing. Most people tend to use chest breathing subconsciously, which greatly reduces the training effect and may even aggravate the body burden due to improper breathing.

[0003] However, some existing diaphragmatic breathing auxiliary devices generally need to rely on external equipment such as the inflation degree of the air bag to roughly reflect the depth of breathing, which cannot provide real-time and accurate guidance for patients and is difficult to help patients form correct breathing habits. At the same time, the existing devices have obvious shortcomings in body position adaptability. When patients lie down for training, the waist is often in a suspended state, which can easily cause soreness and affect the continuity of training. When using a sitting position for training, the waist lacks effective support and is prone to bending, which can cause breathing difficulties and reduce training efficiency. In addition, some devices require an external oxygen source, which is not only inconvenient to carry but also has the safety hazard of gas leakage, and cannot flexibly adjust the oxygen supply according to the training needs.

[0004] The utility model discloses a kind of abdominal breathing training devices for lung function rehabilitation training. Including oxygen inhalation device, deck chair and abdominal contraction device;Abdominal contraction device includes waist support adjusting support device, telescopic adjusting device, automatic winding mechanism, contraction cloth, clamping mechanism and pulling device;Telescopic adjusting device is fixedly installed on deck chair;Waist support adjusting support device is fixedly installed on telescopic adjusting device;Automatic winding mechanism is fixedly installed at the bottom of waist support adjusting support device;Pulling device is fixedly connected with waist support adjusting support device;Contraction cloth one end is fixedly installed in automatic winding mechanism, and the end of contraction cloth away from automatic winding mechanism is sequentially through pulling device and waist support adjusting support device and extends;Clamping mechanism is fixedly installed at the end of contraction cloth away from automatic winding mechanism.The technical solution is pressed by elastic resin pad to patient's abdomen when exhaling by hydraulic cylinder, and it is difficult to control pressing degree by simply pressing by hydraulic cylinder to push elastic resin pad, so that different body type people cannot be trained, and the range of extrusion is single, and different body type human abdomen cannot be extruded in all directions, so that extrusion effect is poor, and abdominal breathing effect is affected. SUMMARY

[0005] In order to overcome the above-mentioned defects of the prior art, the present application provides an abdominal breathing training device for lung function training to solve at least part of the technical problems raised in the above background art.

[0006] To achieve the above-mentioned purpose, the first aspect of the present application provides an abdominal breathing training device for lung function training, which comprises: a positioning plate; a storage gas bag installed on the positioning plate and used to contact the user's abdomen; the storage gas bag has a first storage chamber and a second storage chamber which are isolated from each other; a gas generating mechanism installed on the positioning plate and used to supply gas to the first storage chamber and the second storage chamber; a collection gas bag installed on the positioning plate and in communication with the first storage chamber; a gas pump in communication between the second storage chamber and the collection gas bag for gas transfer between the second storage chamber and the collection gas bag; an output pipeline in communication with the second storage chamber at one end and used for the user to inhale at the other end; a sound generator installed on the positioning plate; a control assembly installed between the positioning plate and the storage gas bag and capable of adjusting the volume of the sound generator with the expansion and contraction of the storage gas bag.

[0007] The specific technical effects of this embodiment are as follows: The above technical solution, through the coordination of the positioning plate, storage airbag, gas generating device, collection airbag, air pump, output pipe, sound generator, and control components, allows the user to push the storage airbag with their abdomen when inhaling, and the control components to act accordingly and simultaneously amplify the volume of the sound generator. When exhaling, the airbag rebounds and the volume decreases, forming intuitive auditory feedback and guiding the user to naturally adopt abdominal breathing. At the same time, the gas generating device supplies oxygen or hydrogen to the two storage chambers as needed, the air pump realizes hydrogen circulation, and the output pipe delivers oxygen directly to the mouth and nose. This ensures a continuous and sufficient supply of gas required for breathing training, and avoids waste and risks through hydrogen recovery, thereby improving the safety, comfort, and effectiveness of training.

[0008] Optionally, the control component includes a volume control knob for controlling the volume of the speaker and a drive component for driving the volume control knob to rotate, wherein the drive component is connected to the storage air bladder; when the storage air bladder contracts and the user inhales using diaphragmatic breathing, the drive component can control the volume control knob to rotate; when the storage air bladder expands, the drive component can control the volume control knob to rotate in the opposite direction.

[0009] The specific technical effects of this embodiment are as follows: by setting a volume control knob and a drive component, each contraction or expansion of the storage airbag can be immediately converted into the forward and reverse rotation of the knob, and the volume will rise or fall accordingly. Users can judge whether the breathing depth and rhythm are up to standard simply by the strength of the sound, without the need for additional display or operation, reducing the learning difficulty and enhancing the training immersion. At the same time, the mechanical linkage structure is simple and reliable, avoiding the delay or false alarm caused by electronic sensors, and ensuring the stability of long-term use.

[0010] Optionally, the drive assembly includes a first transmission component and a second transmission component that are mutually driven and cooperate with each other. The first transmission component is fixedly connected to or integrally formed with the volume control knob, and the second transmission component is connected to the storage airbag and slidably mounted on the positioning plate. When the storage airbag contracts and the user inhales using abdominal breathing, the second transmission component moves towards the positioning plate and drives the first transmission component to rotate. When the storage airbag inflates, the second transmission component moves away from the positioning plate and drives the first transmission component to rotate in the opposite direction.

[0011] The specific technical effects of this embodiment are as follows: through the sliding engagement of the first transmission component and the second transmission component, the linear displacement of the airbag is accurately converted into the rotational movement of the knob. There is no idle stroke in the transmission process, and the volume change is synchronized with the height of the abdominal rise and fall, allowing the user to obtain real-time and linear auditory guidance, further helping them to establish a conditioned reflex of "inhalation - volume increase, exhalation - volume decrease", accelerating the formation of the correct breathing pattern. Moreover, the sliding structure occupies little space, which is conducive to the thinning of the device.

[0012] Optionally, the control component further includes a protective tube, which is fixedly connected to the positioning plate; the inner cavity of the protective tube forms a sliding channel for the second transmission component.

[0013] The specific technical effects of this embodiment are as follows: the protective tube provides a closed sliding channel for the second transmission component, which not only prevents the transmission component from shifting or jamming, but also isolates the gas leakage inside the airbag, ensuring both transmission accuracy and airbag sealing reliability, avoiding the intrusion of external dust and sweat that could lead to mechanism failure, thereby extending the product life and maintaining long-term consistency of volume feedback.

[0014] Optionally, the first transmission member has an inner hole and an inner sidewall for forming the inner hole, the inner sidewall has an internal thread, the second transmission member can at least partially extend into the inner hole, and the outer sidewall of the extended portion of the second transmission member has an external thread for engaging with the internal thread. Alternatively, the first transmission component includes a gear, and the second transmission component includes a rack, wherein the gear and the rack mesh; Alternatively, at least two meshing grooves are provided on the circumferential wall of the first transmission component, and at least two meshing teeth are fixedly connected to the upper surface of the second transmission component, wherein the meshing teeth cooperate with the meshing grooves.

[0015] The specific technical effects of this embodiment are as follows: by using the meshing methods of internal and external threads, gears and racks, or meshing grooves and meshing teeth, minute linear displacements can be efficiently converted into knob angle changes. The transmission ratio is stable, the volume adjustment is delicate and smooth, and there will be no jumps or noises. It provides users with continuous and gentle auditory cues, reduces abruptness, and enhances the training experience. Both solutions have mature processes and can be flexibly selected according to product size and cost.

[0016] Optionally, the gas generating mechanism includes: Storage battery Two decomposition boxes are used to hold electrolyzed water; Two conductors, one end of which is connected to the positive terminal of the battery and the other end of which extends into the electrolyzed water in one of the decomposition boxes; the other end of which is connected to the negative terminal of the battery and the other end of which extends into the electrolyzed water in another decomposition box. A connecting pipe, the two ends of which are respectively connected to the two decomposition boxes; The electrolytic cell for connecting to the negative terminal of the battery is connected to the first storage chamber, and the electrolytic cell for connecting to the positive terminal of the battery is connected to the second storage chamber.

[0017] The specific technical effects of this embodiment are as follows: The battery electrolyzes the water in the two decomposition boxes through positive and negative conductors respectively. The positive electrode produces oxygen and the negative electrode produces hydrogen. The oxygen is directly supplied to the second storage chamber for the user to inhale. After entering the first storage chamber, the hydrogen is collected and recovered by the gas collection bag. The connecting pipeline maintains the liquid level and pressure balance of the two boxes, realizing the integration of water electrolysis, gas separation and classified storage. It eliminates the cumbersome and leakage risk of external oxygen cylinders, greatly reduces the size of the device, and allows training to be carried out anytime and anywhere. In addition, the hydrogen is centrally managed to prevent the escape of flammable gas, and the safety is significantly improved.

[0018] Optionally, the gas generating mechanism further includes two connecting boxes, which are mounted on the positioning plate in a manner that allows them to rotate around their own axis, and the two decomposition boxes are respectively fixedly installed inside the connecting boxes.

[0019] The specific technical effects of this embodiment are as follows: the connecting box can rotate freely around the positioning plate, and the decomposition box keeps its opening facing upwards. No matter whether the user is lying down, sitting or standing, the electrolyzed water will not flow back into the exhaust pipe, ensuring smooth gas output. At the same time, the rotating structure absorbs external shaking, reduces electrolyzed water splashing, maintains stable electrolysis efficiency, allows for more freedom of training posture, and adapts to different rehabilitation scenarios.

[0020] Optionally, the gas generating mechanism further includes a drive motor and a stirring assembly; the stirring assembly is fixed to one end of the conductor located inside the electrolysis box, and the drive motor is used to drive the stirring assembly to rotate.

[0021] The specific technical effects of this embodiment are as follows: the drive motor drives the stirring component to rotate, continuously stirring the electrolyzed water, which not only prevents solute precipitation that leads to uneven conductivity, but also accelerates the detachment of bubbles from the electrode surface, improving gas production efficiency and purity, so that the oxygen supply can respond to the user's breathing rhythm in a timely manner, avoiding the embarrassment of "anaerobic inhalation" or "overflow of oxygen supply", making the training process more continuous and comfortable.

[0022] Optionally, the abdominal breathing training device further includes a strap, a Velcro hook, and a Velcro tab; one end of the strap is installed on one side of the positioning plate; one of the Velcro hook and the Velcro tab is installed on the movable end of the strap, and the other of the Velcro hook and the Velcro tab is installed on the other side of the positioning plate.

[0023] The specific technical effects of this embodiment are as follows: the strap, together with the Velcro and Velcro tabs, enables quick one-handed dressing and tightness adjustment, adapts to people with different waist sizes, requires no tools to put on and take off, and the tightness can be finely adjusted, ensuring that the positioning plate fits tightly to the abdomen, so that the control components can accurately sense the rise and fall of the abdomen and the volume feedback is not distorted; the Velcro structure is soft, avoiding the pressure of traditional buckles on the skin and improving the comfort of wearing for a long time.

[0024] Optionally, the abdominal breathing training device further includes a lumbar support plate; the lumbar support plate is mounted on the positioning plate by the straps and is located on the side of the storage airbag away from the positioning plate.

[0025] The specific technical effects of this embodiment are as follows: the lumbar support board is fixed to the lower back with straps, forming a front and rear clamp with the positioning plate. When lying flat, the lumbar support board lifts the lower back and suspends it, reducing soreness. When sitting, it restricts the curvature of the lumbar spine and keeps the airway open. The two work together to keep the user in a physiological curvature that is conducive to diaphragmatic movement, reduce the loss of respiratory efficiency caused by improper posture, and further improve the effect of abdominal breathing training.

[0027] 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.

[0028] like Figures 1-9As shown, this embodiment of the present disclosure provides an abdominal breathing training device for lung function training, which includes a positioning plate 1, a waist support plate 2 provided on one side of the positioning plate 1, and a storage air bag 3. The storage air bag 3 is fixedly connected to the side wall of the positioning plate 1 and is located between the positioning plate 1 and the waist support plate 2. The storage air bag 3 is used to store gas.

[0029] The gas generating mechanism includes a connecting box 4, an electrolysis box 5, a conductor 39, and a drive motor 29. The connecting box 4 is rotatably connected to the positioning plate 1. The electrolysis box 5 is fixedly connected to the inner wall of the connecting box 4 and is used to hold electrolyzed water. An exhaust pipe 6 is fixedly connected to the top of the electrolysis box 5, and the exhaust pipe 6 is connected to the storage gas bladder 3. The upper end of the conductor 39 is rotatably connected to the top of the electrolysis box 5, and the lower end of the conductor 39 is fixedly connected to a stirring assembly 40. The stirring assembly 40 is used to stir the electrolyzed water in the electrolysis box 5. The stirring assembly 40 consists of multiple sets of stirring rods arranged vertically, with at least two stirring rods in each set, arranged in a ring on the conductor 39. The length of the stirring rods gradually increases from bottom to top, and the stirring rods are made of conductive materials such as aluminum or aluminum alloy. The drive motor 29 is located on the top of the electrolysis box 5 and is used to drive the rotation of the conductor 39. Specifically, the drive motor 29 drives the conductor 39 to rotate via the first gear 30. There are two first gears 30, which are respectively fixedly connected to the output shaft of the drive motor 29 and the conductor 39. The two first gears 30 mesh with each other, and both first gears 30 are made of insulating material. By driving the conductor 39 to rotate via the drive motor 29, the stirring assembly 40 stirs the electrolyzed water at the bottom of the electrolysis box 5. This not only prevents the formation of sediment in the electrolyzed water, but also promotes the generation of bubbles through the rotation of the stirring assembly 40, thereby further improving the efficiency of oxygen and hydrogen production.

[0030] The sound generator 7 is fixedly connected to the positioning plate 1. The sound generator 7 is connected to the volume control knob 8 via a wire. The storage airbag 3 is equipped with a control component, which is used to control the rotation of the volume control knob 8.

[0031] A strap 9 is fixedly connected to the side wall of the positioning plate 1. A hook and loop fastener 10 is fixedly connected to the side wall of the positioning plate 1 away from the strap 9. A hook and loop fastener 11 is fixedly connected to the side wall of the strap 9. The hook and loop fastener 11 is close to the free end of the strap 9 and cooperates with the hook and loop fastener 10.

[0032] The side wall of the lumbar support board 2 has a strip-shaped through hole 12 for the strap 9 to pass through. The free end of the strap 9 passes through the strip-shaped through hole 12 and is fixed to the hook and loop fastener 10 through the Velcro 11. The strap 9 is made of elastic material. The positioning plate 1 and the lumbar support board 2 are fixed to the user's waist and abdomen through the strap 9. That is, the positioning plate 1 is fixed to the user's abdomen and the lumbar support board 2 is fixed to the user's lower back. When the user is lying flat and performing abdominal breathing exercises, the lumbar support board 2 supports the user's waist and prevents the user's waist from being suspended, thereby improving the user's comfort when performing abdominal breathing exercises in a lying position.

[0033] When a user performs abdominal breathing exercises in a seated position, the lumbar support 2 stabilizes the user's waist, preventing the waist from bending during the exercise and thus improving the efficiency of the exercise.

[0034] Both the connecting box 4 and the electrolysis box 5 are spherical in shape. A rotating shaft 13 is fixedly connected to the outer wall of the connecting box 4. A circular through hole 14 is opened on the side wall of the positioning plate 1. The rotating shaft 13 is rotatably connected to the side wall of the circular through hole 14. An electrolyte injection tube is fixedly connected to the top of the electrolysis box 5. The upper end of the electrolyte injection tube passes through the top of the electrolysis box 5 and is flush with the outer wall of the electrolysis box 5. A piston is inserted into the upper end of the electrolyte injection tube. Both the electrolysis box 5 and the connecting box 4 are made of transparent material, which makes it easy for users to observe the usage of the electrolyte in the electrolysis box 5. When the user injects electrolyte into the electrolysis box 5, since both the connecting box 4 and the electrolysis box 5 are spherical, the connecting box 4 is rotatably connected to the positioning plate 1. Due to the gravity of the electrolyte at the bottom of the electrolysis box 5, when the positioning plate 1 is fixed horizontally or vertically to the user's abdomen, the bottom of the connecting box 4 is rotated downwards, so that the upper ends of the connecting box 4 and the electrolysis box 5 are always facing upwards. This allows the gas inside the electrolysis box 5 to be discharged through the exhaust pipe 6 on its upper side. The exhaust pipe 6 is a telescopic flexible hose, which allows the lower end of the exhaust pipe 6 to rotate with the rotation of the connecting box 4.

[0035] A connecting rod 15 is fixedly connected to the inner wall of the connecting box 4, and one end of the connecting rod 15 is fixedly connected to the outer wall of the electrolysis box 5.

[0036] One of the connection boxes 4 is fixedly connected to the top of a first conductive block 16, and the other connection box 4 is fixedly connected to the top of a second conductive block 17. The first conductive block 16 and the second conductive block 17 are in contact with the upper end of the conductor 39.

[0037] A battery 18 is installed inside the positioning plate 1. The first conductive block 16 is connected to the positive terminal of the battery 18 via a wire, and the second conductive block 17 is connected to the negative terminal of the battery 18 via a wire. The positive and negative terminals of the battery 18 are electrically connected to the second conductive block 17 and the first conductive block 16 via a control switch. When the control switch is activated, the battery 18 transmits power to the conductor 39 via the wires connected to it, the first conductive block 16, and the second conductive block 17, and then transmits the power to the stirring assembly 40 via the conductor 39. The conductor 39 and the stirring assembly 40 connected to the positive terminal of the battery 18 undergo an oxidation reaction with the electrolyzed water to generate oxygen. The oxygen enters the second storage chamber 22 for storage through the exhaust pipe 6 on the side of the first conductive block 16. The conductor 39 and the stirring assembly 40 in contact with the second conductive block 17 undergo a reduction reaction to generate hydrogen. The hydrogen enters the gas collection bladder 24 for storage through the exhaust pipe 6 on the side of the second conductive block 17.

[0038] The wires on the battery 18 pass through the center of the rotating shaft 13 and extend into the connecting box 4. The rotating shaft 13 has through holes for the wires to pass through, which facilitates the connecting box 4 to drive the electrolytic box 5 to rotate. This also prevents the wires on the battery 18 from twisting during the rotation of the electrolytic box 5, thus avoiding damage to the wires.

[0039] A connecting pipe 19 is provided on the outside of the connecting box 4. The two ends of the connecting pipe 19 pass through the bottom of the two connecting boxes 4 and are connected to the electrolysis box 5.

[0040] A vertically arranged diaphragm 20 is fixedly connected to the inner wall of the storage airbag 3. The interior of the storage airbag 3 is divided into a first storage chamber 21 and a second storage chamber 22 by the diaphragm 20. The exhaust pipe 6 near the first conductive block 16 is connected to the second storage chamber 22. An output pipe 27 is fixedly connected to the top of the second storage chamber 22.

[0041] The bottom of the first storage chamber 21 is fixedly connected to a discharge pipe 28, which passes through the bottom of the positioning plate 1 and extends to the lower side of the positioning plate 1.

[0042] An arc-shaped groove 23 is provided on the side wall of the positioning plate 1. A collection air bag 24 is fixedly connected to the open end of the arc-shaped groove 23. The exhaust pipe 6 near the second conductive block 17 is fixedly connected to the bottom of the collection air bag 24. The storage air bag 3, the diaphragm 20 and the collection air bag 24 are all made of elastic materials such as butyl rubber and neoprene rubber, which facilitates the storage of oxygen and hydrogen.

[0043] An air pump 25 is fixedly connected to the positioning plate 1. The air pump 25 is a miniature gas delivery pump, and its port is connected to the collection air bag 24 and the first storage chamber 21 respectively through the delivery pipe 26. Specifically, the air pump 25 is a bidirectional delivery pump such as a diaphragm pump, which facilitates the delivery of hydrogen in the collection air bag 24 to the first storage chamber 21. When it is necessary to transfer the hydrogen in the first storage chamber 21 to the collection air bag 24, the air pump 25 can be used again to deliver the hydrogen in the first storage chamber 21 to the collection air bag 24.

[0044] The control component also includes a drive component that drives the volume control knob 8 to rotate. This drive component is connected to the storage air bladder 3. When the storage air bladder 3 contracts and the user inhales using diaphragmatic breathing, the drive component controls the volume control knob 8 to rotate. When the storage air bladder 3 inflates, the drive component controls the volume control knob 8 to rotate in the opposite direction. By configuring the volume control knob 8 and the drive component, each contraction or expansion of the storage air bladder 3 is immediately translated into forward or reverse rotation of the knob, causing the volume to rise or fall accordingly. Users can judge whether their breathing depth and rhythm are up to standard simply by the volume of the sound, without the need for additional display or operation. This reduces the learning curve and enhances the training immersion. Furthermore, the mechanical linkage structure is simple and reliable, avoiding delays or false alarms caused by electronic sensors and ensuring long-term stability.

[0045] As an optional implementation, the drive assembly includes a first transmission component and a second transmission component 32 that are mutually driven and engaged. The first transmission component is fixedly connected to or integrally formed with the volume control knob 8, and the second transmission component 32 is connected to the storage airbag 3 and slidably mounted on the positioning plate. When the storage airbag 3 contracts and the user inhales using abdominal breathing, the second transmission component 32 moves towards the positioning plate and drives the first transmission component to rotate. When the storage airbag 3 expands, the second transmission component 32 moves away from the positioning plate and drives the first transmission component to rotate in the opposite direction. Through the sliding engagement of the first transmission component and the second transmission component 32, the linear displacement of the storage airbag 3 is precisely converted into the rotational movement of the volume control knob 8. There is no idle travel during the transmission process, and the volume change is highly synchronized with the rise and fall of the abdomen, allowing the user to obtain real-time, linear auditory guidance. This further helps the user establish a conditioned reflex of "inhalation - volume increase, exhalation - volume decrease," accelerating the formation of the correct breathing pattern. Moreover, the sliding structure occupies little space, which is beneficial for the thinness and lightness of the device.

[0046] The control assembly also includes a protective tube 31, which is located inside the storage airbag 3. Both ends of the protective tube 31 pass through the diaphragm 20 and are fixedly connected to the inner wall of the storage airbag 3. The portion of the protective tube 31 connected to the diaphragm 20 is made of a rigid material. When the protective tube 31 is fixed and passes through the diaphragm 20, it facilitates a secure connection between the protective tube 31 and the diaphragm 20, while simultaneously preventing gas in the first storage chamber 21 from entering the second storage chamber 22 through the gap between the outer ring wall of the protective tube 31 and the diaphragm 20. The interior of the protective tube 31 forms a sliding channel for the second transmission component 32.

[0047] As an optional implementation, the first transmission member has an inner hole and an inner sidewall for forming the inner hole, the inner sidewall is provided with an internal thread, the second transmission member 32 is at least partially able to extend into the inner hole, and the outer sidewall of the extended portion of the second transmission member 32 is provided with an external thread for engaging with the internal thread.

[0048] Alternatively, in other embodiments, the first transmission member may also include a gear, and the second transmission member 32 may include a rack, with the gear and rack meshing.

[0049] Alternatively, in other embodiments, the first transmission member may also have at least two meshing grooves 33 on its circumferential wall, and the upper surface of the second transmission member 32 may be fixedly connected with at least two meshing teeth 34, which cooperate with the meshing grooves 33.

[0050] The sound generator 7 is connected to a rotary potentiometer via a wire. The volume control knob 8 is mounted on the rotary potentiometer using existing technology. By rotating the volume control knob 8, the volume of the sound generator 7 is adjusted. When the user inhales, the gas in the storage bladder 3 decreases, causing the user's abdomen to protrude. This protrusion pushes the side wall of the storage bladder 3, which is in contact with the user's abdomen, towards the positioning plate 1. This, in turn, pushes the second transmission component 32 towards the positioning plate 1. As the second transmission component 32 moves, it engages and drives the rotation of the volume control knob 8. As the user inhales more gas, the user's abdomen protrudes further, causing the volume of the sound generator 7 to increase as the second transmission component 32 pushes the volume control knob 8. This facilitates the user's abdominal breathing training by adjusting their breathing pattern through abdominal rise and fall, thus improving the efficiency of the user's abdominal breathing training.

[0051] A base 35 is provided on the lower side of the positioning plate 1, and a groove 36 is provided on the base 35 for placing the positioning plate 1.

[0052] The base 35 has a recovery chamber 37 for recovering gas. The recovery chamber 37 cooperates with the first storage chamber 21 and is used to collect hydrogen gas in the first storage chamber 21.

[0053] An intake pipe 38 is fixedly connected to the bottom of the groove 36, and the lower end of the exhaust pipe 28 can be inserted into the intake pipe 38. A check valve is installed in the exhaust pipe 6. Automatic control valves in the prior art are installed in the output pipe 27, the exhaust pipe 28, and the intake pipe 38 to control the opening and closing of the output pipe 27, the exhaust pipe 28, and the intake pipe 38.

[0054] Working principle: The user fixes the device to the waist and abdomen using elastic straps 9: the positioning plate 1 fits against the abdomen, the lumbar support plate 2 fits against the lower back, and the free end of the strap 9 passes through the strip-shaped through hole 12 on the lumbar support plate 2 and is then tightly attached to the Velcro 10 using Velcro pads 11 to ensure the device is stable. When the user is lying down for abdominal breathing training, the lumbar support plate 2 can support the user's waist and prevent discomfort caused by the user's waist being suspended in the air. When the user is sitting, it can restrict the bending of the waist and ensure proper body posture during training, providing a stable foundation for breathing training. The user first adds electrolyzed water through the electrolyte injection tube at the top of the electrolysis box 5. After injection, the tube opening is sealed with a piston. Since the spherical connecting box 4 and the electrolysis box 5 are transparent, it is easy for the user to observe the remaining electrolyte. The connecting box 4 is rotatably connected to the side wall of the circular through hole 14 of the positioning plate 1 through the rotating shaft 13. Under the gravity of the electrolyte at the bottom of the electrolysis box 5, the electrolysis box 5 always keeps its top facing upward, regardless of whether the positioning plate 1 is in a horizontal or vertical state, to prevent the electrolyte from entering the exhaust pipe 6, thereby ensuring that the gas is discharged smoothly. After the control switch connected to the storage battery 18 is turned on, the storage battery 18 supplies power to the conductor 39 through wires, the first conductive block 16 and the second conductive block 17. The current is conducted to the stirring assembly 40 through the conductor 39. The conductor 39 connected to the positive terminal of the storage battery 18 and the stirring rod undergo an oxidation reaction to generate oxygen, which enters the second storage chamber 22 of the storage bladder 3 through the exhaust pipe 6. The conductor 39 connected to the negative terminal and the stirring rod undergo a reduction reaction to generate hydrogen, which enters the collection bladder 24 through the exhaust pipe 6 on another electrolysis box 5.

[0055] The diaphragm 20 inside the storage bladder 3 divides it into a first storage chamber 21 and a second storage chamber 22. The first storage chamber 21 stores hydrogen produced in the electrolytic box 5 connected to the cathode of the battery 18, and the second storage chamber 22 stores oxygen produced in the electrolytic box 5 connected to the anode of the battery 18. When the user needs oxygen during abdominal breathing training, the control switch on the battery 18 is turned on, and the drive motor 29 is started. The drive motor 29 drives the conductor 39 to rotate through two meshing first gears 30. When multiple sets of stirring rods with increasing length from bottom to top rotate, it can prevent electrolyte precipitation and promote bubble generation, thereby improving gas production efficiency. The exhaust pipe 6 is a telescopic hose that can be flexibly adjusted with the rotation of the connecting box 4 to ensure smooth gas transmission. Oxygen enters the second storage chamber 22 through the exhaust pipe 6 above the electrolytic box 5 connected to the battery 18. At this time, the automatic control valve in the exhaust pipe 6 opens, and as the amount of oxygen in the second storage chamber 22 increases... The storage bladder 3 gradually inflates, compressing the user's abdomen and prompting exhalation. Simultaneously, the user aligns the outlet pipe 27 with their nose or mouth. As the user inhales, the automatic control valve in the outlet pipe 27 opens, while the automatic control valve in the exhaust pipe 6 closes. Oxygen from the second storage chamber 22 is discharged through the outlet pipe 27 and inhaled by the user. As the oxygen in the second storage chamber 22 decreases, the user's abdomen expands outwards during oxygen inhalation, compressing the outer wall of the storage bladder 3 and pushing the side wall of the second storage chamber 22. This causes the second transmission component 32 within the protective tube 31 to move towards the positioning plate 1. The meshing teeth 34 on the second transmission component 32 engage with the meshing groove 33 of the volume control knob 8, rotating the knob. The volume of the sound generator 7 increases with the depth of inhalation, providing feedback to guide the user to master the correct abdominal breathing rhythm.

[0056] During the user's exhalation, the automatic control valve in the exhaust pipe 6 above the electrolytic box 5, which is connected to the anode of the battery 18, opens, and the oxygen in the electrolytic box 5 re-enters the second storage chamber 22. As the oxygen in the second storage chamber 22 increases, the storage air bladders 3 expand, causing the second transmission component 32 to move away from the sound generator 7. This causes the second transmission component 32 to drive the volume control knob 8 to rotate in the opposite direction. At this time, the volume component of the sound generator 7 decreases. This process is repeated to guide the user to perform abdominal breathing training.

[0057] When the user inhales oxygen from the electrolytic cell 5 connected to the anode of the battery 18, the hydrogen produced in the electrolytic cell 5 connected to the cathode of the battery 18 enters the gas collection bladder 24 for storage through the exhaust pipe 6 above it. When the user no longer needs to use the oxygen from the electrolytic cell 5 connected to the anode of the battery 18, the user turns off the control switch on the battery 18. When the user exhales, the micro gas delivery pump 25 is activated. The micro gas delivery pump 25 delivers the hydrogen from the gas collection bladder 24 to the first storage chamber 21 through the delivery pipe 26. As the amount of hydrogen in the first storage chamber 21 increases, the storage bladder 3 gradually expands. The expanded storage bladder... 3. The system compresses the user's abdomen to prompt the user to exhale through abdominal breathing. When the user inhales, the micro gas delivery pump 25 delivers hydrogen from the first storage chamber 21 to the collection bladder 24, so that the user's abdomen protrudes and pushes against the second transmission component 32 during inhalation. The volume of the sound generator 7 then prompts the user on the efficiency of abdominal breathing training. At the same time, the micro gas delivery pump 25 causes the collection bladder 24 to contract and expand during the input and output of hydrogen, thus simulating the user's abdominal breathing training and prompting the user to practice abdominal breathing again.

[0058] When the user completes the abdominal breathing training, the user manually separates the Velcro patch 11 on the strap 9 from the Velcro hook 10 on the positioning plate 1, removes the positioning plate 1 and the waist support plate 2, and places the positioning plate 1 and the waist support plate 2 into the groove 36 on the base 35, thereby storing the positioning plate 1 and the waist support plate 2. When there is a large amount of hydrogen stored in the collection airbag 24 and it is necessary to release the hydrogen in the collection airbag 24, when the positioning plate 1 is placed in the groove 36, the discharge pipe 28 is inserted into the air intake pipe 38, and the automatic control valve and the micro gas delivery pump 25 in the discharge pipe 28 and the air intake pipe 38 are activated. The micro gas delivery pump 25 delivers hydrogen to the first storage chamber 21, and allows the hydrogen to enter the recovery chamber 37 through the discharge pipe 28 and the air intake pipe 38, thereby realizing the recovery of hydrogen and avoiding hydrogen pollution to the air.

[0059] In summary, the above-described embodiments have the following beneficial effects: The device is securely fixed to the waist and abdomen by the combination of the strap 9 and the lumbar support board 2. The lumbar support board 2 provides lumbar support and fixation in lying and sitting positions, respectively, to avoid lumbar discomfort or bending, improve comfort and stability during training, ensure that training can be carried out in the standard posture, and improve training efficiency.

[0060] The electrolysis system, consisting of electrolysis box 5, conductor 39, and stirring assembly, generates oxygen and hydrogen through the electrolysis of water. The oxygen can be used to assist in lung function training, providing the necessary gas for training and meeting the gas supply requirements during the training process. At the same time, the driving assembly drives the stirring assembly to rotate, effectively stirring the electrolyzed water. This prevents the formation of precipitates in the electrolyte from affecting the electrolysis reaction and promotes bubble generation, accelerating the production rate of oxygen and hydrogen, ensuring a sufficient gas supply during training.

[0061] By using the sound generator 7 in conjunction with the control components, the user's abdominal movements are converted into changes in volume. Through sound feedback, the user is guided to adjust their breathing rhythm and depth, helping them to more accurately master the abdominal breathing method and enhancing the targetedness and effectiveness of lung function training.

[0062] The gas is divided into two storage chambers by a diaphragm in the storage bladder 3, storing oxygen and hydrogen respectively. The collection bladder is specifically for collecting hydrogen, achieving classified storage of the gases. The recovery chamber in the base can recover hydrogen, preventing indiscriminate gas emissions, which is both environmentally friendly and safe, while also facilitating gas recycling or subsequent processing.

[0063] By designing the connecting box 4 and the electrolysis box 5 as spherical and rotating them with the positioning plate, the upper end of the connecting box 4 and the electrolysis box 5 are always facing upwards when the positioning plate is fixed horizontally or vertically, ensuring that the gas can be discharged smoothly, adapting to different training postures of the user, and improving the practicality of the device.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
