Description

Technical Field

[0001] This invention belongs to the field of breathing training device technology, specifically a breathing training device with adjustable resistance. Background Technology

[0002] In modern society, with the increasing health awareness and focus on the rehabilitation needs of special populations, respiratory function training has gradually become an important part of medical rehabilitation, sports and fitness, and daily health care. Breathing trainers, as tools to assist in improving respiratory muscle strength and lung ventilation, are widely used in the rehabilitation treatment of patients with chronic obstructive pulmonary disease (COPD), respiratory endurance training for athletes, lung function recovery for postoperative patients, and improving respiratory efficiency in healthy individuals.

[0003] Traditional breathing trainers have significant limitations in resistance adjustment. Early, simple trainers often used fixed resistance designs, such as providing resistance through a single-aperture airway or a valve with a fixed elastic coefficient, which could only meet training needs of a single intensity. However, respiratory function varies significantly among different populations: the respiratory muscle strength of healthy adults differs greatly from that of elderly patients, the training intensity requirements of those with mild respiratory dysfunction are drastically different from those of severely ill patients, and the physical condition of the same user can change at different training stages. Fixed resistance trainers cannot flexibly adjust the difficulty according to individual differences and training progress, which can easily lead to poor training results—too little resistance makes it difficult to achieve the required training intensity, while too much resistance may cause respiratory muscle fatigue or even damage, affecting user compliance.

[0004] Therefore, this invention provides a breathing trainer with adjustable resistance. Utility Model Content

[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a breathing trainer with adjustable resistance is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a breathing trainer with adjustable resistance, comprising a breathing apparatus shell; a mouthpiece is movably mounted on one side of the breathing apparatus shell; an adjustment component is provided on the surface of the breathing apparatus shell near the mouthpiece; a drive mechanism is provided on the inner wall of the breathing apparatus shell; a transmission component is provided at the end of the rotating rod away from the screw; an air-blocking mechanism is provided on the surface of the screw; a quick-release component is provided on the side of the breathing apparatus shell near the mouthpiece; the adjustment component includes a rotating ring and a limiting ring, the two sides of the rotating ring are fixedly installed with the limiting ring, and the rotating ring is rotatably mounted on one side of the inner wall of the breathing apparatus shell through the limiting ring; the cooperation of the rotating ring and the limiting ring allows the user's rotation to drive the gear ring to rotate, thereby enabling power transmission, while the limiting ring ensures that the rotating ring can rotate stably on the inner wall of the breathing apparatus shell.

[0007] Preferably, the driving mechanism includes a rotating rod, a screw, and a limiting plate. Two sets of rotating rods are provided, and the two sets of rotating rods are rotatably installed on the top and bottom of the inner wall of the respirator housing. One end of the rotating rod is fixedly installed with the screw, and the end of the screw away from the rotating rod is fixedly installed with the limiting plate. In this scheme, the cooperation between the rotating rod and the screw can drive the air-blocking mechanism to move by rotation, thereby enabling it to adjust the resistance. The limiting plate can limit the air-blocking mechanism and prevent it from moving off the surface of the screw.

[0008] Preferably, the transmission assembly includes a driven tooth and a toothed ring. The driven tooth is fixedly installed at the end of the rotating rod away from the screw, and the toothed ring is fixedly installed on the inner wall of the rotating ring. The driven tooth meshes with the toothed ring. In this scheme, the cooperation between the driven tooth and the toothed ring can achieve rotation through the drive of the rotating ring and transmit rotational energy to the rotating rod to make it rotate.

[0009] Preferably, the air-blocking mechanism includes a threaded plate, a spring, and an air-blocking mesh ball. The threaded plate is threaded onto the surface of the screw. The side of the threaded plate away from the mouthpiece is fixedly installed with the spring. The side of the spring away from the threaded plate is fixedly installed with the air-blocking mesh ball. The surface of the air-blocking mesh ball has a funnel-shaped groove, with the larger opening of the funnel-shaped groove facing the threaded plate. In this design, the threaded plate can move continuously as the screw rotates. The spring can generate resistance through its own elasticity. The air-blocking mesh ball can prevent air from directly entering the interior of the respirator shell. At the same time, the funnel-shaped groove on the surface of the air-blocking mesh ball allows the user to inhale a smaller amount of air and exhale quickly.

[0010] Preferably, a filter screen is fixedly installed on the inner wall of the respirator housing on the side away from the mouth. In this design, the filter screen can filter the inhaled air and prevent dust or impurities from being inhaled into the lungs and causing irreversible damage to the body.

[0011] Preferably, the quick-release assembly includes a threaded ring and an internal thread. The threaded ring is fixedly installed on the side of the respirator housing near the mouthpiece, and the internal thread is formed on the inner wall of the mouthpiece. The mouthpiece is threaded onto the surface of the threaded ring through the internal thread. In this design, the use of the threaded ring and the internal thread enables the mouthpiece to be quickly replaced, thereby facilitating disassembly and disinfection and improving safety during use.

[0012] The beneficial effects of this utility model are as follows: 1. The present invention discloses a resistance-adjustable breathing trainer, which, through the arrangement of a rotating ring, a limiting ring, a rotating rod, a screw, and a limiting plate, enables the rotating ring and the limiting ring to work together to drive the gear ring to rotate, thereby transmitting power. At the same time, the limiting ring ensures that the rotating ring can rotate stably on the inner wall of the breathing apparatus shell. The rotating rod and the screw work together to drive the air-blocking mechanism to move through rotation, thereby enabling resistance adjustment. The limiting plate limits the air-blocking mechanism to prevent it from moving off the surface of the screw.

[0013] 2. The adjustable resistance breathing trainer of this utility model, through the arrangement of driven teeth, toothed rings, threaded plates, springs, and air-blocking mesh balls, enables the driven teeth and toothed rings to rotate through the drive of the rotating ring, and transmits the rotational energy to the rotating rod to make it rotate. The threaded plate can move continuously following the rotation of the screw. The spring can generate resistance through its own elasticity. The air-blocking mesh ball can prevent air from directly rushing into the interior of the breathing apparatus shell. At the same time, the funnel-shaped groove on the surface of the air-blocking mesh ball can make the user take in a smaller amount of air when inhaling, and exhale the air quickly when exhaling.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 4As shown in the embodiment of this utility model, an adjustable resistance breathing trainer includes a breathing apparatus shell 1; a mouthpiece 2 is movably mounted on one side of the breathing apparatus shell 1, an adjustment component 3 is provided on the surface of the breathing apparatus shell 1 near the mouthpiece 2, and a drive mechanism 4 is provided on the inner wall of the breathing apparatus shell 1; a transmission component 5 is provided at the end of the rotating rod 41 away from the screw 42, and an air-blocking mechanism 6 is provided on the surface of the screw 42; a quick-release component 8 is provided on the side of the breathing apparatus shell 1 near the mouthpiece 2; the adjustment component 3 includes a rotating ring 31 and a limiting ring 32, the two sides of the rotating ring 31 are fixedly installed with the limiting ring 32, and the rotating ring 31 is rotatably mounted on one side of the inner wall of the breathing apparatus shell 1 through the limiting ring 32; the drive mechanism 4 includes a rotating rod 41, a screw 42, and a limiting plate 43, two sets of rotating rods 41 are provided, the two sets of rotating rods 41 are rotatably mounted on the top and bottom of the inner wall of the breathing apparatus shell 1, one end of the rotating rod 41 is fixedly installed with the screw 42, and the end of the screw 42 away from the rotating rod 41 is fixedly installed with the limiting plate 43. Position plate 43 is fixedly installed. Transmission assembly 5 includes driven tooth 51 and toothed ring 52. Driven tooth 51 is fixedly installed at the end of rotating rod 41 away from screw 42. Toothed ring 52 is fixedly installed on the inner wall of rotating ring 31. Driven tooth 51 meshes with toothed ring 52. Air blocking mechanism 6 includes threaded plate 61, spring 62 and air blocking mesh ball 63. Threaded plate 61 is threaded onto the surface of screw 42. The side of threaded plate 61 away from nozzle 2 is fixedly installed with spring 62. Spring 62 is located away from threaded plate 61. One side of the respirator housing 1 is fixedly installed with the air-blocking mesh ball 63. The surface of the air-blocking mesh ball 63 is provided with a funnel-shaped groove, with the larger opening of the funnel-shaped groove facing the threaded plate 61. A filter screen 70 is fixedly installed on the inner wall of the respirator housing 1 away from the mouthpiece 2. The quick-install assembly 8 includes a threaded ring 81 and an internal thread 82. The threaded ring 81 is fixedly installed on the side of the respirator housing 1 near the mouthpiece 2. The internal thread 82 is opened on the inner wall of the mouthpiece 2. The mouthpiece 2 is threaded onto the surface of the threaded ring 81 through the internal thread 82.

[0020] like Figures 1 to 4As shown, the interaction between the rotating ring 31 and the limiting ring 32 allows the user's rotation to drive the gear ring 52 to rotate, thereby transmitting power. Simultaneously, the limiting ring 32 ensures that the rotating ring 31 rotates stably on the inner wall of the respirator housing 1. The interaction between the rotating rod 41 and the screw 42 allows rotation to drive the air-blocking mechanism 6 to move, thus enabling resistance adjustment. The limiting plate 43 limits the air-blocking mechanism 6, preventing it from moving off the surface of the screw 42. The interaction between the driven tooth 51 and the gear ring 52 allows the rotating ring 31 to drive rotation and transmit rotational energy to the rotating rod 41, enabling it to move forward. The screw plate 61 rotates continuously, following the rotation of the screw 42. The spring 62 generates resistance through its own elasticity. The air-blocking mesh ball 63 prevents air from directly entering the respirator housing 1. At the same time, the funnel-shaped groove on the surface of the air-blocking mesh ball 63 allows the user to inhale a smaller amount of air and exhale quickly. The filter 70 filters the inhaled air, preventing dust or impurities from being inhaled into the lungs and causing irreversible damage to the body. The use of the threaded ring 81 and the internal thread 82 allows the mouthpiece 2 to be quickly replaced, making it easy to disassemble and disinfect, thereby improving the safety of use.

[0021] Working principle: During operation, the user first picks up the mouthpiece 2 and aligns it with the threaded ring 81. Then, the mouthpiece 2 is installed on one side of the respirator housing 1. The user then puts the mouthpiece 2 in their mouth and bites it with their teeth. When the user inhales, the air pressure inside the respirator housing 1 decreases, allowing external air pressure to enter through the filter 70 and move into the respirator housing 1 through the air-blocking mesh ball 63. Because the air-blocking mesh ball 63 has poor ventilation, air pushes it to one side, compressing the spring 62 and preventing it from blocking the air inlet, thus increasing the air intake. After inhalation, the user exhales. Following exhalation, the funnel-shaped opening on the surface of the air-blocking mesh ball 63... The larger end of the hole faces the mouth 2, so when the user exhales, a large amount of air will be discharged through the through holes on the surface of the air-blocking mesh ball 63. When inhaling again, because the air inlet at the end of the funnel is very small, the air intake will be less than the pressure difference, so the air-blocking mesh ball 63 will be pushed open. When the resistance needs to be adjusted, the user needs to rotate the rotating ring 31 to drive the toothed ring 52 to rotate. The rotation of the toothed ring 52 will drive the two sets of driven teeth 51 to rotate. When the driven teeth 51 rotate, they will drive the rotating rod 41 and the screw 42 to rotate. The rotation of the screw 42 will drive the threaded plate 61 to move. As the threaded plate 61 moves continuously, the spring 62 will be compressed. As the spring 62 is compressed, the user needs more force to push the air-blocking mesh ball 63 to one side when inhaling again.
