It's designed to assist with breathing exercises, strengthening the lungs and respiratory muscles through inhalation and exhalation exercises. Designed to operate at varying breathing resistance levels, spirometers enable users to breathe more deeply and effectively. They are commonly used in rehabilitation, athletic training, and general health care. By using a spirometer, people can improve lung function, strengthen their respiratory system, increase oxygen intake, and improve the body's efficiency in utilizing oxygen. These devices are beneficial for people with respiratory conditions and those seeking to improve their physical endurance and fitness.

[0003] Chinese patent publication number CN116899186A discloses a protective breathing training device, which is connected to the breathing training passage fluid through the inner cavity of the gas filter component. The inhaled and exhaled gases are purified by the gas filter component before entering the human respiratory tract or the external environment, ensuring two-way protection during inhalation and exhalation; and the three-dimensional gas filter component doubles the area of ​​the gas filter component in a limited space, while ensuring the purification effect, the air resistance during inhalation or exhalation is minimized. By replacing the breathing training component and the gas barrier component, independent exhalation training, inhalation training, or a mode of simultaneous exhalation and inhalation training can be achieved, and the air resistance level required for training can be adjusted according to the scale mark, and can be changed at any time according to the needs of the user, with simple and convenient operation.

[0004] When adjusting the breathing resistance, that is, the training intensity, of the breathing trainer in the above scheme, the user needs to first remove the breathing trainer and then manually turn it to adjust it, which will interrupt their training process and affect the training effect. At the same time, after manual adjustment, the user needs to wear it for a try to know the specific breathing resistance, which will make it difficult for the user to accurately control the resistance level and waste too much time in adjustment.

[0005] Therefore, it is necessary to provide a resistance-adjustable lung capacity training device to solve the above problems. Summary of the Invention

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] See also Figures 1-16A resistance-adjustable lung capacity training device comprises: a trainer body 1, an adjustment component 2 and an air resistance component 6. The trainer body 1 comprises a cylinder 11 and a sealing cover 12. The cylinder 11 and the sealing cover 12 are integrally formed. The sealing cover 12 is close to the inner side of the lips. Two bite blocks 15 are fixedly installed on the inner side of the sealing cover 12. The bite block 15 is located between the upper and lower teeth. A mounting groove 17 is provided on the top of the bite block 15. A vent 2 110 is provided at one end of the cylinder 11. The adjustment component 2 comprises a bite airbag 1 21, a bite airbag 2 22 and a trachea 1 23. The bite airbag 1 21 and the bite airbag 2 22 are respectively fixedly installed in the mounting groove 17 on the top of the two bite blocks 15. One end of the trachea 1 23 is connected to the bite airbag 1 21, and the outer end of the bite airbag 2 22 is fixedly installed with a The connected trachea 24 has the other end connected to the trachea 1 23, the occlusal airbag 1 21, the occlusal airbag 2 22, the trachea 1 23 and the interior of the trachea 2 24 are interconnected, and a driving device 25 is installed at the end of the trachea 1 23 away from the occlusal airbag 1 21, and the air curtain 1 62 and the air curtain 2 63 are used to control the flow size of the vent 2 110. The occlusal airbag 1 21 and the occlusal airbag 2 22 are both in contact with the upper teeth. The occlusal airbag 1 21 and the occlusal airbag 2 22 automatically adjust the internal gas to enter the driving device 25 through the force of the teeth biting. The driving device 25 adjusts the breathing resistance by pushing the air curtain 1 62 to move through the incoming gas. The distance that the air curtain 1 62 moves is directly proportional to the volume of the gas entering the driving device 25.

[0025] The cylinder 11 is provided with a vent 2 110 and a vent assembly 3 is installed at one end, and the other end of the cylinder 11 is provided with a vent 13, a drying assembly 7 is arranged inside the vent 13, a filter assembly 4 is arranged at one end of the vent assembly 3, and a control assembly 5 is arranged at the other end of the vent assembly 3 and inside the filter assembly 4 to control the gas circulation.

[0026] The device in this solution is mainly used for respiratory training of the lungs. Compared with traditional training devices, it has a smaller volume, so it can be worn for training while exercising. The trainer body 1 is made of silicone, so an integrated mold forming process can be adopted. The trainer body 1 is mainly composed of a cylinder 11 and a sealing cover 12. The sealing cover 12 is arranged in an arc shape so that it can match the upper and lower gums of the user. When worn, it can fit closely to the gums of the user. Ventilation port 2 110 and vent 1 13 are respectively provided at both ends of the cylinder 11. Ventilation port 13 is provided at the position where the cylinder 11 is connected to the sealing cover 12, and an air resistance component 6 is provided on the inner side of the vent 2 110. The air resistance component 6 is mainly used to control the internal ventilation volume of the vent 2 110, that is, to adjust the breathing resistance. An adjustment component 2 is also provided on the inner side of the sealing cover 12. The adjustment component 2 is mainly used to drive the air resistance component 6 to adjust the breathing resistance. By wrapping the sealing cover 12 in the mouth so that the sealing strip 14 is against the gums, and then letting the upper and lower teeth bite the bite block 15, when the user bites the bite block 15 hard, the bite airbag 1 21 and the bite airbag 2 22 will be squeezed. Since the bite airbag 1 21 and the bite airbag 2 22 are connected to the driving device 25 through the trachea 1 23 and the trachea 2 24, and the movable plate 621 is driven by the driving device 25, the movable plate 621 controls the adjustment of the breathing resistance. Therefore, when the user needs to adjust the breathing resistance, it is only necessary to change the strength of the teeth biting the bite block 15 to complete the adjustment. Adjustments are made according to the user's real-time needs, and there is no need to manually adjust the resistance. The user can save time and focus more on training, thereby improving training efficiency.

[0027] At the vent 2 110, the ventilation component 3 is detachably connected. The ventilation component 3 is mainly used to install the filter component 4 and two control components 5. The filter component 4 is mainly used to filter the air, and the control component 5 plays the role of one-way ventilation. By threading the filter component 4 at one end of the vent tube 31, the inhaled air can be filtered. At the same time, control components 5 are set on both sides of the vent tube 31. The two control components 5 are installed in opposite directions. The control component 5 set on the filter component 4 is used for air intake, and the other is used for air exhaust. Since the gas exhaled by the human body contains more water vapor, the linkage control of the two control components 5 makes the air not pass through the filter component 4 when it is exhausted, which can prevent the filter 44 from being soaked by water vapor and prevent the filter 44 from breeding bacteria, thereby improving safety and service life.

[0028] Optionally, in some embodiments, see Figures 1-4, pull rings 18 are fixedly connected on both sides of the cylinder 11, a sealing strip 14 is fixedly installed on the outer edge of the sealing cover 12, the sealing strip 14 is tightly attached to the gums to form a seal, a plurality of snap rings 19 are fixedly installed on the outer end of the cylinder 11, and baffles 16 are fixedly installed on the top and bottom ends of the bite block 15, and the baffles 16 are against the inner wall of the oral cavity.

[0029] The vent 13 and the vent 2 110 provided at both ends of the cylinder 11 are connected to each other, so that the gas can pass through the cylinder 11. A sealing strip 14 is fixed at the outer edge of the sealing cover 12, and the sealing strip 14 also rests against the gums. After the sealing cover 12 is wrapped by the lips, a gap is easily generated between the sealing cover 12 and the gums as the user moves. Since the sealing strip 14 protrudes from the surface of the sealing cover 12 and is thicker than the sealing cover 12, it can improve the sealing performance and prevent air from flowing out from between the sealing cover 12 and the gums. Pull rings 18 are fixed on both sides of the cylinder 11. When the user adjusts the trainer body 1 in the mouth, the pull rings 18 can be used to adjust it, thereby improving the convenience of use. Two bite blocks 15 are fixed on the inner side of the sealing cover 12. In addition to being used to install the adjustment component 2, the bite block 15 can also be used to fix the trainer body 1 by the teeth biting the bite block 15. The upper and lower ends of the bite block 15 are fixed with baffles 16. When the user bites the bite block 15, the baffle 16 will be located on the inside of the mouth. The baffle 16 will be against the inner gums and can be stuck in the mouth, which can prevent the trainer body 1 from falling out and improve stability.

[0030] Optionally, in some embodiments, see Figure 5 and Figure 6 The driving device 25 includes a shell 251 and a piston 254. A connecting port 253 is provided at the outer end of the shell 251. The air pipe 23 is connected to the interior of the shell 251 through the connecting port 253. A partition 252 is fixedly installed on the inner wall of the shell 251. The piston 254 is slidably connected to the inner wall of the shell 251. A push rod 256 is fixedly installed on the outer end of the piston 254. The push rod 256 passes through the inner wall of the shell 251 and extends to the outside. The push rod 256 is located in the shell 251 and is sleeved with a telescopic spring 255 at one end. The two ends of the telescopic spring 255 are respectively against the piston 254 and the inner wall of the shell 251. The piston 254 is pushed by the gas delivered into the interior of the shell 251 by the air pipe 23. After being pushed by the piston 254, the push rod 256 is reset by the telescopic spring 255.

[0031] The bite airbag 1 21 and the bite airbag 2 22 in this solution have the same shape and volume. The bite airbag 1 21 and the bite airbag 2 22 can be installed on the bite block 15 through the installation groove 17 opened on the inner side of the bite block 15. However, when the bite airbag 1 21 and the bite airbag 2 22 are installed in the installation groove 17, they will be slightly higher than the installation groove 17 and extend to the top of the bite block 15, so that the user can more easily squeeze the bite airbag 1 21 and the bite airbag 2 22 when biting the bite block 15.

[0032] The outer ends of the bite airbag 1 21 and the bite airbag 2 22 are fixedly connected to the trachea 1 23 and the trachea 2 24 respectively, and the end of the trachea 2 24 is connected to the trachea 1 23, so that the bite airbag 1 21 and the bite airbag 2 22 can be connected to each other. The trachea 1 23 and the trachea 2 24 are both tightly attached to the inner wall of the cylinder 11. The end of the trachea 1 23 is connected to the driving device 25. The outer end of the shell 251 is provided with a connecting port 253. The end of the trachea 1 23 is connected to the connecting port 253, and the trachea 1 23 is connected to the interior of the shell 251 through the connecting port 253. The piston 254 is slidably connected to the inside of the shell 251, and a partition 252 is fixed on the inner wall of the shell 251. The partition 252 is mainly used to block the controller stroke of the piston 254. The push rod 256 is fixed to the outer end of the piston 254, and the other end of the push rod 256 passes through the shell 251 and extends to the outside. A telescopic spring 255 is surrounded by the end of the push rod 256 located inside the shell 251. The telescopic spring 255 is located inside the shell 251, and the two ends of the telescopic spring 255 are respectively against the piston 254 and the inner wall of the shell 251.

[0033] The extended end of the push rod 256 is connected to the movable plate 621. Therefore, when it is used to perform breathing training after biting the bite block 15, when it is necessary to adjust the breathing resistance, it is only necessary to increase the force to bite the bite block 15, or reduce the force to bite the bite block 15, so as to control the amount of gas in the bite airbag 1 21 and the bite airbag 2 22 flowing into the shell 251, so that the piston 254 inside the shell 251 can move. Since the push rod 256 is driven by the piston 254, the movement of the piston 254 can drive the push rod 256 to drive the movable plate 621 to move, thereby changing the breathing resistance. Compared with the traditional adjustment method, the user can continuously adjust the breathing resistance during exercise. When the user exercises more easily, the breathing resistance can be increased, and when exercising vigorously, the breathing resistance can be reduced, so that it can better match the training and improve the training effect.

[0034] Optionally, in some embodiments, see Figure 7-Figure 9The air resistance component 6 also includes a mounting plate 61, which is fixedly mounted on the inner wall of the vent 2 110. A mounting groove 2 65 is provided at the outer end of the mounting plate 61. Air curtain 1 62, air curtain 2 63 and resetter 64 are all located inside the mounting groove 2 65. Air curtain 1 62 includes a movable plate 621. A plurality of equidistantly distributed vent holes 1 622 are provided at the outer end of the movable plate 621. Sliders 623 are fixedly mounted on both sides of the movable plate 621. Slide grooves matching the slides 623 are provided on both sides of the interior of the mounting groove 2 65. The movable plate 621 is slidably connected to the slide groove through the slide 623 and moves in the mounting groove 2 65. One end of the push rod 256 is connected to the push rod 256. The outer end of the movable plate 621 is fixedly connected, and the resetter 64 includes an elastic strip 1 641 and an elastic strip 2 642. The elastic strip 1 641 and the elastic strip 2 642 are both arranged in an arc shape. The outer ends of the elastic strip 1 641 and the elastic strip 2 642 are fixedly installed with a connecting block 643. The two ends of the elastic strip 1 641 are respectively rotatably connected to the two ends of the elastic strip 2 642. The elastic strip 1 641 is fixedly connected to the outer end of the movable plate 621 through the connecting block 643. The elastic strip 2 642 is fixedly connected to the inner side wall of the mounting groove 2 65 through the connecting block 643. The elastic strip 1 641 and the elastic strip 2 642 push the movable plate 621 to reset through their own elastic force.

[0035] The air curtain 2 63 includes a fixing plate 631, which is fixedly mounted on the inner wall of the mounting groove 2 65. A plurality of equally spaced second vent holes 632 are provided at the outer end of the fixing plate 631. The breathing resistance is adjusted by changing the overlapping area of ​​the vent holes 1 622 and the vent holes 2 632.

[0036] The air resistance component 6 in this scheme is mainly used to adjust the breathing resistance, wherein the mounting plate 61 is fixed on the inner wall of the vent 2 110, and a mounting groove 2 65 is provided at the outer end of the mounting plate 61. The air curtain 1 62, the air curtain 2 63 and the resetter 64 are all located in the mounting groove 2 65, wherein the air curtain 1 62 is mainly composed of a movable plate 621, and a plurality of equidistantly distributed air holes 1 622 are provided at the outer end of the movable plate 621, while the air curtain 2 63 is mainly composed of a fixed plate 631, and a plurality of vent holes 2 632 are provided at the outer end of the fixed plate 631. The air holes 1 622 and the air holes 2 632 are the same. When the air holes 1 622 and the air holes 2 632 completely overlap, the flow rate in the channel is the largest. On the contrary, when they are completely staggered, the channel will be closed, and air cannot circulate.

[0037] The fixed plate 631 is fixed on the inner wall of the second mounting groove 65 and cannot be moved, while sliders 623 are fixed on both sides of the movable plate 621. Two sliding grooves are opened on the inner wall of the second mounting groove 65, and the sliders 623 are slidably connected with the sliding grooves. Therefore, when the push rod 256 drives the movable plate 621 to move in the second mounting groove 65, the overlapping area of ​​the vent hole 1 622 and the vent hole 2 632 can be changed, thereby changing the breathing resistance.

[0038] The resetter 64 is mainly composed of an elastic strip 1 641 and an elastic strip 2 642. The two ends of the elastic strip 1 641 are respectively connected to the two ends of the elastic strip 2 642 for rotation. The elastic strip 1 641 and the elastic strip 2 642 are both supported by metal sheets and are arranged in an arc shape with a certain elasticity. Connecting blocks 643 are fixed on the elastic strip 1 641 and the elastic strip 2 642. The connecting blocks 643 are used to install the elastic strip 1 641 and the elastic strip 2 642. The elastic strip 1 641 is fixed to the movable plate 621 through the connecting blocks 643, and the elastic strip 2 642 is fixed to the inner side wall of the mounting groove 2 65 through the connecting blocks 643. When the movable plate 621 is driven by the push rod 256 to move toward the resetter 64, it will squeeze Elastic strip 1 641 and elastic strip 2 642, when the user reduces the bite force on the bite block 15, the elastic force of the resetter 64 itself will push the resetter 64 to reset the movable plate 621, and at the same time, the telescopic spring 255 inside the shell 251 will also push the piston 254, so that the push rod 256 drives the movable plate 621 to reset. Therefore, the telescopic spring 255 and the resetter 64 have the same function, and are both used to assist the fixed plate 631 in resetting. Through the cooperation of the telescopic spring 255 and the resetter 64, the user can reduce the squeeze on the bite airbag 1 21 and the bite airbag 2 22, and the fixed plate 631 can quickly cooperate with it to adjust the breathing resistance, thereby achieving the purpose of rapid adjustment.

[0039] Optionally, in some embodiments, see Figure 10 The drying component 7 includes a limiting plate 71 and a drying sheet 73. The limiting plate 71 is fixedly mounted on the inner wall of the cylinder 11. A slot 72 matching the drying sheet 73 is provided on the inner side of the limiting plate 71. The drying sheet 73 is mounted on the inner side of the limiting plate 71 through the slot 72. The drying sheet 73 is made of non-woven fabric and is used to absorb moisture inside the cylinder 11.

[0040] The drying component 7 in this scheme is mainly used to keep the inside of the cylinder 11 dry. The limiting plate 71 is arranged in an arc shape and is fixedly installed close to the inner wall of the cylinder 11. A slot 72 is provided on the inner side of the limiting plate 71. The slot 72 is mainly used to install a drying sheet 73, and the drying sheet 73 is stuck in the inside of the slot 72. It is worth mentioning that the top of the limiting plate 71 is hollowed out so that the drying sheet 73 can be exposed. The drying sheet 73 is mainly made of non-woven fabric. Since the user will inevitably drool when breathing, and water droplets will condense in the cylinder 11 when breathing, by arranging a drying sheet 73 at the bottom end of the cylinder 11, the moisture will slide down the inner wall of the cylinder 11 to the bottom. At this time, the drying sheet 73 can absorb it, so that the interior remains relatively dry, thereby improving the comfort and hygiene of use. The drying sheet 73 is replaceable and can be replaced with a new one after use.

[0041] Optionally, in some embodiments, see Figure 11 The ventilation assembly 3 includes a ventilation cylinder 31, a connecting groove 35 is provided at the outer end of the ventilation cylinder 31, and the connecting groove 35 is detachably connected to the outer end of the cylinder body 11 through a clamping ring 19. An air outlet 33 and an air inlet 34 are respectively provided at both ends of the ventilation cylinder 31. A counterweight ring 32 is fixedly installed at one end of the ventilation cylinder 31 with the air outlet 33.

[0042] The ventilation assembly 3 in this scheme is mainly composed of a breather cylinder 31. The breather cylinder 31 has a three-way structure. The beginning of the breather cylinder 31 is respectively provided with a connecting groove 35, an air outlet 33 and an air inlet 34. The outer end of the cylinder body 11 is provided with a snap ring 19. The breather cylinder 31 is detachably connected to the cylinder body 11 by snapping the connecting groove 35 and the snap ring 19. The control assembly 5 is installed inside the air outlet 33. The installation direction of the control assembly 5 is opposite to that of the control assembly 5 in the filter assembly 4. The air inlet 34 is threadedly connected to the mounting cover 41, so that the filter assembly 4 can be detachably mounted on the breather cylinder 31. It is worth mentioning that a counterweight ring 32 is fixed on the outside of one end of the air outlet 33 of the breather cylinder 31. Since the filter assembly 4 is installed at the air inlet 34, the weight added by the counterweight ring 32 can keep the left and right sides of the breather cylinder 31 balanced, so that the user can maintain better balance when exercising.

[0043] Optionally, in some embodiments, see Figure 11-14 The filter assembly 4 includes a mounting cover 41, the outer end of the mounting cover 41 is provided with an anti-slip pattern 42, the mounting cover 41 is threadedly connected to one end of the ventilator 31 with an air inlet 34, the filter assembly 4 also includes a filter box 43 and a plurality of filter discs 44, the filter box 43 is detachably mounted inside the mounting cover 41, a mounting post 45 is fixedly mounted at the inner center of the filter box 43, the mounting post 45 passes through a plurality of filter discs 44, a side air hole 46 is provided at the outer edge of the filter box 43, a through hole 47 is provided at the outer end of the filter box 43, an annular groove 48 is provided on the inside of the filter box 43, the annular groove 48 is connected to the side air hole 46, and the filter disc 44 is mounted on the inside of the filter box 43 through the annular groove 48.

[0044] The filter assembly 4 in this solution is mainly used to filter the air inhaled by the user. The outer end of the mounting cover 41 is provided with an anti-slip groove 42 for increasing friction. The mounting cover 41 is threadedly connected to the air inlet 34. A filter box 43 is detachably mounted inside the mounting cover 41. A mounting post 45 is fixed on the inner side of the filter box 43 near the center of the circle. The mounting post 45 passes through multiple filter discs 44 and strings the filter discs 44 on the inner side of the filter box 43. The filter discs 44 are mainly used to filter the inhaled air. Side air holes 46 are opened around the outer side of the filter box 43, and the filter box 43 has a plurality of side holes 46. An annular groove 48 is provided on the inner side, which is connected to the side air hole 46, so that the side air hole 46 can be connected to the interior of the filter box 43, which plays a role in ventilation. At the same time, the annular groove 48 can clamp the edge of the filter 44 installed in the filter box 43, thereby improving the stability of the installation of the filter 44. A large through hole 47 is also provided at the outer end of the filter box 43, and the through hole 47 is also used for ventilation. When the user inhales, the control component 5 installed inside the installation cover 41 will open, allowing air to enter and be filtered by the filter 44 before being inhaled, thereby improving the safety of breathing.

[0045] Optionally, in some embodiments, see Figure 15 and Figure 16 The control component 5 includes a plurality of air baffles 51 of successively decreasing lengths, and a plurality of rotating shafts 52 matching the air baffles 51. The air baffles 51 are rotatably mounted on the inner side of the mounting cover 41 via the rotating shafts 52. A magnet 53 is mounted on the outer side of the air baffle 51. The control component 5 also includes a plurality of limit baffles 54. The plurality of limit baffles 54 are all fixedly mounted on the inner side of the mounting cover 41. The air baffles 51 are magnetically attracted to the limit baffles 54 by the magnets 53 and abut against each other to form a seal.

[0046] The control component 5 in this scheme mainly plays the role of one-way ventilation. The control component 5 installed in the air outlet 33 and the control component 5 installed in the mounting cover 41 are in opposite directions, so that they cannot be opened at the same time. The control component 5 is mainly composed of multiple air baffles 51. The multiple air baffles 51 decrease in length from the middle to the sides, so that they can form a circular shape, matching the mounting cover 41 and the air outlet 33. Each air baffle 51 is rotatably installed inside the mounting cover 41 through a rotating shaft 52. At the same time, a magnet 53 is fixed on the outer end of each air baffle 51, and the limit baffle 54 is also fixed on the mounting cover 41. It is worth mentioning that the control component 5 installed in the air outlet 33 is installed in the same way as the mounting cover 41, wherein the limit baffle 54 installed in the mounting cover 41 is located on the outside and is made of metal, while the limit baffle 54 installed in the air outlet 33 is located inside the air outlet 33. Therefore, the installation directions of the two control components 5 are opposite. When the user inhales, the limit baffle 54 installed in the installation cover 41 is located outside and will not block the air baffle 51. At this time, the air baffle 51 rotates inward and opens, and air is inhaled through the filter assembly 4. When the user exhales, the limit baffle 54 in the installation cover 41 will block the air baffle 51, making it close to the limit baffle 54 to form a seal. On the contrary, the control assembly 5 installed in the air outlet 33 will open to allow the air to be discharged. Since the exhaled air of the human body contains more water vapor, the two control assemblies 5 are controlled to prevent the user from exhaling through the filter assembly 4 and being discharged from the air outlet 33. This can prevent the filter 44 from being soaked by water vapor, prevent the filter 44 from breeding bacteria, and improve safety and service life.

[0047] Working principle: When using the device, you first need to wear the trainer body 1, put the sealing cover 12 into your mouth, make the sealing strip 14 close to the gums, and bite the teeth on the bite block 15. The sealing cover 12 and the baffle 16 are located on both sides of the teeth to clamp them. At this time, you can breathe without using your nose, only using your mouth, to train your breathing. When it is necessary to adjust the breathing resistance, you only need to increase the force to bite the bite block 15, or reduce the force to bite the bite block 15, so as to control the amount of gas in the bite airbag 1 21 and the bite airbag 2 22 flowing into the shell 251. The movement of the piston 254 can drive the push rod 256 to drive the movable plate 621 to move. When the push rod 256 drives the movable plate 621 to move in the installation groove 2 65, the overlapping area of ​​the vent 1 622 and the vent 2 632 can be changed, thereby changing the breathing resistance. During strenuous exercise, the breathing resistance can be reduced, and conversely, the resistance can be increased, so that it can better match the training and improve the training effect.
