Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a breathing training device. Background Technology

[0002] Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS, OSAS) is a condition characterized by pauses in breathing due to obstructive lesions of the upper airway (including collapse of the pharyngeal mucosa), with snoring being the primary symptom. Many factors contribute to obstructive sleep apnea syndrome, with weak airway muscles being a common cause. These factors include weakness, thickening, and crowding of the neck and pharyngeal muscles. Treatment methods for snoring typically include surgical removal, anti-snoring devices, and exercise-based weight loss therapies.

[0003] Anti-snoring therapy is currently the main method for preventing snoring during sleep. This involves using a CPAP machine, anti-snoring patches, mouthguards, or belts before bed to keep the airway clear during sleep. However, because these devices need to be worn constantly during sleep, patient acceptance is low, and snoring often resumes once the device is removed. Therefore, anti-snoring therapy only treats the symptoms, not the root cause. Exercise for weight loss can fundamentally address respiratory muscle weakness caused by obesity, but it requires a certain amount of space and time. Most people are too busy to find suitable places for weight loss exercise, and the effects of exercise are mainly on the surface of the body, without effectively strengthening the muscles of the throat and nasal cavity.

[0004] However, respiratory muscle weakness is a major cause of nasopharyngeal diseases and related conditions. Therefore, strengthening and improving respiratory muscle training can effectively improve snoring. One way to strengthen and improve respiratory muscle training is to use a training device, which works by applying exhalation or inhalation to the device and using the vibration waves generated by the device to treat snoring and improve respiratory muscle strength.

[0005] However, existing training devices have the following drawbacks: parameters such as the frequency and cumulative time of breathing exercises rely entirely on personal recording. Individuals often cannot fully record the training parameters for each breath due to personal matters and habits, resulting in occasional over- or under-training, leading to an imbalance in each training session and an inability to conduct regular and scientific training, thus affecting the effectiveness of breathing exercises.

[0036] In one embodiment, this utility model discloses a breathing training device 100, comprising: a frame 1, having an inner cavity and an air inlet 13 and an air outlet 14 respectively communicating with the inner cavity; a partition plate 2, housed in the inner cavity to divide the inner cavity into a first cavity 15 and a second cavity 16, the partition plate 2 having a through hole 21 communicating with the first cavity 15 and the second cavity 16; a vibration assembly 3, including a swing arm 31 rotatably disposed within the frame 1 and a valve 32 disposed on the swing arm 31, the valve 32 blocking the through hole 21 when the swing arm 31 swings to a first position and disengaging from the through hole 21 when the swing arm 31 swings to a second position; and a sensor 4, used to detect the vibration sound waves caused by the vibration of the swing arm 31, or the vibration of the frame 1 caused by the vibration, or the air pressure change within the frame 1 caused by the vibration, to determine breathing parameters, such as... Figures 1 to 11 As shown.

[0037] Preferably, the frame 1 is used to facilitate gas flow to help the patient exhale or inhale; the frame 1 can be a cylinder, cuboid, or other geometric shape, or an irregular geometric shape; the frame 1 can be made of metal, plastic, or other materials, etc., without specific limitations; furthermore, the frame 1 has an inner cavity for the flow of the patient's exhaled or inhaled gas to help the patient perform exhalation or inhalation exercises; the shape of the inner cavity can be a cylinder, cuboid, or other geometric shape, etc., or... The frame is an irregular geometric shape, etc.; the air inlet 13 is located at one end of the frame 1 and communicates with the inner cavity, preferably at one end along the length of the frame 1, so that gas can enter the interior of the inner cavity from the air inlet 13; the air outlet 14 is located at the other end of the frame 1 and communicates with the inner cavity, preferably at one end along the length of the frame 1, so that gas can be discharged from the air outlet 14. The arrangement of the air inlet 13, the inner cavity, and the air outlet 14 allows gas to enter the inner cavity from the air inlet 13 and then be discharged from the air outlet 14, realizing unidirectional gas flow, which facilitates the patient's exhalation or inhalation. In other embodiments, the air inlet 13 and the air outlet 14 can also be located at both ends along the width or thickness of the frame 1, or one can be located at one end along the length, width, or thickness of the frame 1 and the other at one end along the width, thickness, or length of the frame 1, etc.

[0038] More preferably, the partition plate 2 is disposed within the inner cavity and is fixedly connected to the frame 1, such as by integral molding, welding, or bonding; the partition plate 2 can be located at the middle position along the length direction of the frame 1, or at one end along the length direction, etc. In this embodiment, the partition plate 2 is located at the middle position along the length direction of the frame 1; the partition plate 2 can extend along the length direction of the frame 1, or along the thickness direction or width direction of the frame 1, in this embodiment, the partition plate 2 extends along the length direction of the frame 1; the partition plate 2 divides the inner cavity of the frame 1 into two independent cavities, namely the first cavity 15 and the second cavity 16, which are located on both sides of the partition plate 2 and are isolated from each other to achieve spatial separation between the two cavities; the shapes of the first cavity 15 and the second cavity 16 can be regular geometric shapes, such as cylinders, The cavity can be a cuboid or an irregular geometric shape; the first cavity 15 is connected to the air inlet 13 so that the gas entering through the air inlet 13 enters the first cavity 15; the second cavity 16 is connected to the air outlet 14 so that the gas in the second cavity 16 is discharged through the air outlet 14; a through hole 21 is provided on the partition plate 21, the through hole 21 penetrates both surfaces of the partition plate 21, one end of the through hole 21 is connected to the first cavity 15 and the other end is connected to the second cavity 16 so as to realize the connection between the first cavity 15 and the second cavity 16, thereby allowing the gas in the first cavity 15 to enter the second cavity 16 through the through hole 21 so as to realize the gas flow between the two cavities; the through hole 21 can be provided in the middle of the partition plate 21 or at one end of the partition plate 21, etc., and can be provided as needed, without specific limitation here.

[0039] Preferably, the vibration component 3 is disposed within the inner cavity of the frame 1 to achieve mechanical vibration. It is driven to vibrate when the patient inhales or exhales, thereby exercising the patient's respiratory muscles. Moreover, the frequency is more adaptable to the patient's inhalation or exhalation, resulting in a more ideal exercise effect on the respiratory muscles. The swing arm 31 is used to swing within the inner cavity to generate vibration waves. These vibration waves cause the respiratory muscles to vibrate, thereby exercising the muscles and achieving the purpose of treating snoring. For patients who cannot expel phlegm independently, the vibration waves cause the airway to vibrate, which can effectively loosen the phlegm adhering to the trachea, thus aiding in phlegm expulsion. Furthermore, the frequency of these vibration waves is between 20Hz and 200Hz, making the exercise effect on the respiratory muscles even more ideal. Valve 32 is mounted on the swing arm 31 and can swing with the swing arm 31. Valve 32 and the swing arm 31 can be integrally formed or fixedly connected, such as by welding or bonding, depending on the requirements. Furthermore, valve 32 can be located in the middle of the swing arm 31 or at one end, depending on the requirements. When the swing arm 31 swings to the first position, valve 32 is partially housed within the through hole 21 and blocks the through hole 21, thus isolating the first chamber 15 from the second chamber 16 and preventing gas from entering the second chamber 16 from the first chamber 15 through the through hole 21. Figure 3 and Figure 4 As shown; when the swing arm 31 swings to the second position, the valve 32 disengages from the through hole 21 and does not block the through hole 21, thereby connecting the first chamber 15 and the second chamber 16. At this time, the gas in the first chamber 15 can enter the second chamber 16 through the through hole 21.

[0040] It should be noted that the second position is any position where the swing arm 31 swings to where the valve 32 does not block the through hole 21, and no specific limitation is made here.

[0041] Preferably, the sensor 4 can be located on the inside of the frame 1 or on the outside of the frame 1. It can be set as needed and is not specifically limited here.

[0042] In some embodiments, the swing arm 31 generates sound waves during its swing. Since the swing arm 31 swings periodically with inhalation or exhalation, the sound waves it generates are periodic, and this period is consistent with the period of inhalation or exhalation. Therefore, the sensor 4 can be a sound wave sensor, which can detect the periodic vibration sound waves generated by the swing arm 31 due to its swing, and then obtain the periodic parameters of the patient's inhalation or exhalation through these periodic sound waves, such as the frequency, number of breaths, and time of inhalation or exhalation. This enables the automatic recording of the parameters of the patient's inhalation or exhalation training, making it convenient for the patient to record these parameters in a timely and accurate manner, ensuring the patient's regular exercise, and facilitating the patient's rapid recovery.

[0043] In some embodiments, the swing arm 31 will collide with the isolation plate 2 and the inner wall of the frame 1 during the swing, thereby causing the frame 1 to vibrate. The periodic parameters of the frame 1 vibration are consistent with the periodic parameters of the patient's exhalation or inhalation. Therefore, the sensor 4 can be a vibration sensing sensor, which can detect the periodic vibration of the frame 1 caused by the swing, and then obtain the periodic parameters of the patient's exhalation or inhalation through the periodic vibration, such as the frequency, number of times, and time of exhalation or inhalation. This enables the automatic recording of the parameters of the patient's exhalation or inhalation training, which is convenient for the patient to record the parameters in a timely and accurate manner, ensuring the patient's regular exercise and facilitating the patient's rapid recovery.

[0044] In some embodiments, during the patient's exhalation or inhalation exercises, the swing arm 31 swings periodically. During this swinging motion, the valve 32 opens and closes periodically. When the valve 32 is open, airflow flows from the first chamber 15 through the through-hole 21 to the second chamber 16, causing the air pressure in the first chamber 15 to gradually decrease and the air pressure in the second chamber 16 to gradually increase. When the valve 32 blocks the through-hole 21, the airflow from the first chamber 15 into the second chamber 16 decreases, thereby increasing the air pressure in the first chamber 15 and decreasing the air pressure in the second chamber 16. Therefore, during the patient's periodic exhalation or inhalation, the air pressure in the first chamber 15 or the second chamber 16 changes periodically, and the period of air pressure change coincides with the patient's exhalation or inhalation cycle. Therefore, sensor 4 can be a barometric pressure sensor, which can detect changes in air pressure in the first chamber 15 or the second chamber 16, and then obtain periodic parameters of the patient's exhalation or inhalation through the periodic vibration, such as the frequency, number of times, and time of exhalation or inhalation, so as to realize the automatic recording of the parameters of the patient's exhalation or inhalation training, so that the patient can record the parameters in a timely and accurate manner and ensure the patient's regular exercise.

[0045] It should be noted that the above respiratory parameters include the patient's breathing frequency, number of breaths, and duration. In other embodiments, other parameters may also be used. Users can set them as needed, and no specific limitations are made here.

[0050] It should also be noted that the microphone sensor is covered with a waterproof and sound-permeable membrane to protect it from water vapor generated during the patient's breathing exercises, preventing it from entering and causing damage. The waterproof and sound-permeable membrane can cover the entire microphone sensor or only a portion of it, such as areas requiring sealing, and can be configured as needed without specific limitations. The waterproof and sound-permeable membrane is an existing technology and can be made of materials such as polypropylene spunbond nonwoven fabric or polyethylene high-molecular breathable membrane, which will not be elaborated further here.

[0059] It should be noted that the pressure sensor is preferably located in the first chamber 15 because the air pressure in the first chamber 15 is relatively high, making the detected data more accurate.

[0060] In one embodiment, when the sensor 4 is used to detect vibration sound waves or vibration of the frame 1, the sensor 4 is fixed inside or outside the frame 1; or, when the sensor 4 is used to detect changes in air pressure, the sensor 4 is fixed inside the frame 1, such as...

[0091] More preferably, the support shaft 33 can be a cylinder, cuboid, or other geometric shape, and its specific shape can be set as needed, without being specifically limited here.

[0092] More preferably, the support shaft 33 is fixedly connected to the frame 1, such as by integral molding, welding, or bonding. The specific connection method can be set as needed and is not specifically limited here.

[0093] Preferably, the support shaft 33 is located inside the second cavity 16 so that the swing arm 31 can swing within the second cavity 16.

[0094] More preferably, one end of the swing arm 31 is a first end 311, which is rotatably connected to the support shaft 33, so that the swing arm 31 swings around the support shaft 33 so that it swings periodically to the first position and the second position to achieve periodic blocking of the through hole 21.

[0095] Furthermore, the second chamber 16 is located between the air outlet 14 and the through hole 21, so that the gas in the first chamber 15 can pass through the through hole 21 into the second chamber 16 and then be discharged from the air outlet 14, realizing one-way gas flow.

[0096] Furthermore, the swing arm 31 is housed in the second cavity 16 so that when it swings to the first position, it blocks the through hole 21 through the valve 32, and when it swings to the second position, it disengages from the through hole 21, thereby achieving periodic blocking of the through hole 21.

[0097] In one embodiment, the frame 1 includes a first partition 11 located at one end of the partition plate 2 and a second partition 12 located at the other end of the partition plate 2. The partition plate 2 is fixedly connected to the first partition 11 and the second partition 12 respectively, and the partition plate 2 extends along the length direction of the frame 1. Figures 1 to 10 As shown.

[0098] Preferably, the first partition 11 is located on the side of the isolation plate 2 near the air inlet 13. The first partition 11 is fixedly connected to the inner wall of the frame 1, such as by integral molding, welding, or bonding. The specific connection method can be set as needed and is not specifically limited here.

[0099] More preferably, the first partition 11 is fixedly connected to the end of the isolation plate 2 near the air inlet 13, such as by bonding, integral molding, welding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0100] More preferably, the first partition 11 can be a geometric shape such as a cuboid or cylinder, or an irregular geometric shape, and its specific shape can be set as needed, without being specifically limited here.

[0101] Preferably, the second partition 12 is located at one end of the isolation plate 2 near the air outlet 14. The second partition 12 is fixedly connected to the inner wall of the frame 1, such as by integral molding, welding, or bonding. The specific connection method can be set as needed and is not specifically limited here.

[0102] More preferably, the second partition 12 is fixedly connected to the end of the isolation plate 2 near the air outlet 14, such as by bonding, integral molding, welding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0103] Furthermore, the second partition 12 can be a geometric shape such as a cuboid or cylinder, or an irregular geometric shape, and its specific shape can be set as needed, without being specifically limited here.

[0104] Furthermore, the combination of the first partition 11, the partition plate 2, and the second partition 12 can divide the inner cavity of the frame 1 into independent first cavity 15 and second cavity 16. The arrangement of the first partition 11 and the second partition 12 allows the partition plate 2 to extend along the length direction of the frame 1, thereby facilitating its cooperation with the swing arm 31 to realize the swing of the swing arm 31 and increase the stability of vibration.

[0105] Furthermore, the isolation plate 2 extends along the length of the frame 1, thereby increasing its surface area so that the swing arm 31 can better fit on the isolation plate 2 when swinging, and the valve 32 can smoothly block the through hole 21, thus achieving stable unidirectional control of the airflow.

[0106] In one embodiment, the breathing training device 100 further includes a first magnet 51 fixed inside the frame 1 and a second magnet 52 fixed to the other end of the swing arm 31 and used to magnetically attract the first magnet 51, such as... Figures 1 to 10 As shown.

[0107] Preferably, the first magnet 51 is fixed to the frame 1, for example, fixed to the inner wall of the frame 1 or fixed to the outer wall of the frame 1, so as to achieve a stable connection between the two.

[0108] More preferably, the first magnet 51 can be a cylindrical, cuboid, or other geometric shape, or an irregular geometric shape, etc., and can be set as needed, without specific limitations here.

[0109] Preferably, the second magnet 52 is fixedly connected to the swing arm 31, such as by adhesive bonding or snap-fit ​​connection.

[0110] Preferably, the second magnet 52 and the first magnet 51 are positioned opposite each other so that they attract each other magnetically, which helps the swing arm 31 to reset in time during the swinging process, thereby allowing the valve 32 to block the through hole 21 and prevent gas backflow.

[0111] More preferably, the second magnet 52 can be disposed at the middle position of the swing arm 31 or at the end of the swing arm 31. In this embodiment, the second magnet 52 is fixed to the end of the swing arm 31.

[0112] It should be noted that during the swinging process, the swing arm 31 drives the second magnet 52 to periodically move away from and towards the first magnet 51. When the second magnet 52 moves away from the first magnet 51, the magnetic attraction of the first magnet 51 to the second magnet 52 can make the swing arm 31 quickly return to its original position, which helps to accelerate the vibration of the swing arm 31 and thus enhance the training effect on the respiratory muscles.

[0113] Furthermore, the other end of the swing arm 31 is the second end 312, and the second magnet 52 is fixed on the second end 312 so that when the swing arm 31 swings, it drives the second magnet 52 to swing accordingly, causing it to periodically approach and move away from the first magnet 51 and the sensor 4.

[0114] Furthermore, the second end 312 is fixedly connected to the second magnet 52, such as by adhesive bonding or snap-fitting. The specific connection method can be set as needed and is not specifically limited here. In this embodiment, the second end 312 is provided with a groove, and the second magnet 52 is housed in the groove and fixedly connected to the second end 312 to increase the connection area between the two and enhance the stability of their connection.

The air inlet connector 18 is used to connect the air inlet 13 of the frame 1 to external devices such as the mouthpiece 200 or the nasal mask 300, or it may not be connected to external devices, so as to enable the patient to practice exhalation and inhalation.

[0117] More preferably, one end of the air intake connector 18 is connected to the air intake port 13 so that the first cavity 15 is in communication with the interior of the air intake connector 18, so that the gas in the air intake connector 18 enters the first cavity 15 through the air intake port 13.

[0118] More preferably, the air intake connector 18 is fixedly connected to the air intake port 13, such as by clipping, welding, or bonding. The fixed connection method can be set as needed and is not specifically limited here.

[0122] In one embodiment, the breathing training device 100 further includes an air outlet connector 93, which communicates with the air outlet 14 and is fixedly connected to the outer casing 9, such as... Figures 1 to 10 As shown.

[0123] Preferably, the air outlet connector 93 is located at the air outlet 14 of the frame 1.

[0129] It should be noted that in some embodiments, since the frame 1 is shorter and the outer shell 9 is longer, an exhaust pipe 19 is provided at the end of the frame 1. The exhaust pipe 19 is located between the exhaust connector 93 and the frame 1. In this case, the exhaust port 14 is located at the end of the exhaust pipe 19 away from the frame 1, so as to achieve connection with the exhaust connector 93. Furthermore, one end of the exhaust pipe 19 is connected to the end of the frame 1, and the second cavity 16 communicates with the interior of the exhaust pipe 19. The other end of the exhaust pipe 19 is connected to the exhaust connector 93 to achieve gas flow.

[0130] In one embodiment, the isolation plate 2 has an arc-shaped protrusion 22, the through hole 21 passes through the protrusion 22, and the valve 32 is conical and is at least partially accommodated within the protrusion 22 when the through hole 21 is blocked. Figure 3 and Figure 4 As shown.

[0131] Preferably, the isolation plate 2 is provided with a protrusion 22, which protrudes toward the first cavity 15 to accommodate at least part of the valve 32.

[0132] More preferably, the protrusion 22 is arc-shaped. In other embodiments, the protrusion 22 may also be other shapes, etc., which are not specifically limited here.

[0133] More preferably, the protrusion 22 and the partition plate 22 can be integrally formed, or they can be fixedly connected by welding, bonding or other methods. The specific connection method can be set as needed and is not specifically limited here.

[0134] Preferably, the through hole 21 extends through the protrusion 22 so that the valve 32 can at least partially pass through the through hole 21 to block the through hole 21 and prevent gas from passing through the through hole 21.

[0135] More preferably, the valve 32 is conical so that it matches the shape of the protrusion 22, facilitating the sealing of the through hole 21. In other embodiments, when the protrusion 22 has a different shape, the shape of the valve 32 matches the shape of the protrusion 22 to seal the through hole 21.

[0136] Furthermore, the valve 32 can be at least partially housed within the protrusion 22 to block the through hole 21, preventing gas from passing through the through hole 21 and ensuring the sealing performance.

[0137] In one embodiment, the breathing training device 100 further includes an extension tube 400 and a connector. One end of the extension tube 400 is connected to the air inlet connector 18 or the air outlet connector 93, and the other end of the extension tube 400 is connected to the connector. Figure 9 and Figure 10 As shown.

[0138] Preferably, the extension tube 400 is elongated and located outside the housing 9, making it easy to connect to the air inlet connector 18 or the air outlet connector 93.

[0139] It should be noted that the connector is used to connect to the mouth or nasal cavity. When the connector is used to connect to the mouth, it is a mouthpiece 200; when the connector is used to connect to the nasal cavity, it is a nose mask 300. It can be set as needed and no specific limitation is made here.

[0140] More preferably, one end of the extension tube 400 is connected to the air inlet connector 18, and the other end is connected to the mouthpiece 200, thereby enabling exhalation or inhalation exercises through the mouthpiece 200.

[0141] It should be noted that the extension tube 400 connects the air inlet connector 18 and the mouthpiece 200, allowing the patient to perform exhalation exercises through the mouthpiece 200. When the patient exhales, the air pressure in the first chamber 15 increases and becomes greater than the air pressure in the second chamber 16. At this time, the valve 32 opens, and the swing arm 31 swings around the support shaft 33. The gas in the first chamber 15 enters the second chamber 16 through the through hole 21. The second end 312 of the swing arm 31 moves away from the isolation plate 2. After colliding with the inner wall of the frame 1, it generates a rebound force, causing the second end 312 of the swing arm 31 to move towards the isolation plate. 2. The valve 32 is moved, causing it to reset and block the through hole 21. At this time, the patient continues to exhale, and the valve 32 opens again. Through the patient's periodic exhalation, the valve 32 moves back and forth periodically, thereby generating vibration waves to cause vibration of the airway, so that the respiratory muscles are fully exercised, thereby achieving the effect of treating snoring. Furthermore, due to the gravity of the valve 32, the magnetic attraction between the first magnet 51 and the second magnet 52, and the rebound force during swinging, the valve 32 is quickly reset, and the resistance of the valve 32 to disengage from the through hole 21 is increased, thereby enhancing the effect of exhalation exercise.

[0142] More preferably, one end of the extension tube 400 is connected to the air outlet connector 93, and the other end is connected to the mouthpiece 200, so that exhalation or inhalation exercises can be achieved through the mouthpiece 200.

[0143] It should be noted that the above-mentioned connections can be fixed connections such as snap-fit ​​or adhesive, which are existing technologies and will not be described in detail here.

[0144] It should be noted that the extension tube 400 connects the air outlet connector 93 and the mouthpiece 200, allowing the patient to perform inhalation exercises through the mouthpiece 200. When the patient inhales, the air pressure in the second chamber 16 decreases and becomes lower than the air pressure in the first chamber 15. At this time, the valve 32 opens, and the swing arm 31 swings around the support shaft 33. The gas in the first chamber 15 enters the second chamber 16 through the through hole 21. The second end 312 of the swing arm 31 moves away from the isolation plate 2. After colliding with the inner wall of the frame 1, it generates a rebound force, causing the second end 312 of the swing arm 31 to move towards the isolation plate 2. The movement causes valve 32 to reset and block the through hole 21. At this time, the patient continues to exhale, and valve 32 opens again. Through the patient's periodic exhalation, valve 32 moves back and forth periodically, thereby generating vibration waves to cause vibration of the airway, which allows the respiratory muscles to be fully exercised, thus achieving the effect of treating snoring. Furthermore, due to the gravity of valve 32, the magnetic attraction between the first magnet 51 and the second magnet 52, and the rebound force generated during swinging, valve 32 quickly resets and increases the resistance of valve 32 to disengage from through hole 21, thus achieving the effect of correct inhalation training.

[0145] It should also be noted that the mouthpiece 200 mentioned above can also be replaced with a nose mask 300, etc., and the settings can be selected according to needs. No specific restrictions are made here.

[0146] It should also be noted that the extension tube 400 allows patients to avoid holding the breathing training device for extended periods of time. The breathing training device 100 can be placed in a backpack or on a table, and patients can sit or lie down. They only need to hold the mouthpiece 200 or the nasal mask 300, making it more convenient to operate.

[0147] In one embodiment, the breathing training device 100 further includes a silencer 7, which is disposed within the air outlet connector 93, the air outlet pipe 19, or the air outlet 14. Figure 7 or Figure 8 As shown.

[0148] Preferably, the silencer 7 is a commercially available silencer, which can be of straight pipe, plate, honeycomb, or other structures, all of which can reduce noise. Here, a straight pipe silencer is preferred. The sound-absorbing material and structure of the straight pipe silencer are directly arranged on the inner wall of the pipe, and the pipe can be circular or rectangular, etc., and the minimum cross-sectional area of ​​the silencer 7 pipe is greater than 30% of the area of ​​the air outlet. Since the airflow flows from the first chamber 15 to the second chamber 16 during exhalation or inhalation, the gas flow needs to be realized as quickly as possible to avoid the airflow stagnating in the first chamber 15 or the second chamber 16 and affecting the vibration of the valve 32. Exhausting is carried out by the silencer 7 pipe having a minimum cross-sectional area greater than 30% of the area of ​​the air outlet 14, which does not affect the vibration of the valve 32 and reduces noise to a certain extent.

[0149] More preferably, the muffler 7 is disposed within the air outlet connector 93 and is fixedly connected to it, such as by snap-fit ​​connection, threaded connection, adhesive bonding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0150] More preferably, the muffler 7 is disposed inside the air outlet pipe 19 and is fixedly connected to it, such as by snap-fit ​​connection, threaded connection, adhesive bonding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0151] Preferably, the muffler 7 is disposed inside the air outlet 14 and is fixedly connected to it, such as by snap-fit ​​connection, threaded connection, adhesive bonding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0152] In one embodiment, the breathing training device 100 further includes a sleeve 17, the frame 1 being housed within and fixedly connected to the sleeve 17, such as... Figure 3 As shown.

[0153] Preferably, the sleeve 17 can be a cuboid, cylinder, or other geometric shape, and its specific shape can be set as needed, without being specifically limited here.

[0154] More preferably, the sleeve 17 can be made of metal or non-metal materials, such as plastic. The specific material can be set as needed and is not specifically limited here.

[0155] More preferably, the frame 1 is housed within the sleeve 17 and fixedly connected thereto, such as by snap-fit ​​connection, adhesive bonding, welding, etc. The specific connection method can be set as needed and is not specifically limited here.

[0156] Preferably, the outer surface of the frame 1 abuts against the inner surface of the sleeve 17 to achieve a stable connection between the two.

[0157] More preferably, the sleeve 17 can be set at the middle position of the outer wall of the frame 1, or at one end of the outer wall of the frame 1, etc. The sleeve 17 can also cover the entire outer wall of the frame 1, and the two ends of the sleeve 17 are coplanar with the two ends of the frame 1, so that the length of the sleeve 17 is consistent with the length of the frame 1. It can be set as needed, and no specific limitation is made here.

[0158] It should be noted that multiple sleeves 17 can also be provided and arranged sequentially at intervals on the outer wall of the frame 1 to enhance the protection of the outer wall of the frame 1.
