[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] By setting up the cooperation of structures such as the whistle seat, the whistle plug, and the whistle opening, when the device is used by child patients to exercise the respiratory function, by integrally installing the whistle seat on the first air duct, a whistle sound can be emitted when the child patient exhales, thereby improving the attention and interest of the child patient and making the child patient use the device to exercise the respiratory function more actively. Further, by pulling the connecting rope and through the reset of the second return spring, the position of the piston disk can be changed, thereby changing the sound of the whistle and improving the interest of the child patient when using it. Furthermore, when adult patients exercise the respiratory function, by removing the whistle seat as a whole and replacing it with an air-blocking plate, noise generated during training can be avoided, thus distracting the attention of adult patients.

[0022] By setting up the cooperation of structures such as the first air duct, the second air duct, and the air-blocking ball, when the patient exhales, the air flow enters the inside of the first air duct and then lifts the second air duct. By controlling the magnetic force between the second electromagnet and the first electromagnet, the air flow volume during breathing can be adjusted, and by setting two groups of air-blocking components, the respiratory muscle strength of the patient can be effectively exercised. And when the first electromagnet and the second electromagnet come into contact, the signal indicator light emits a bright light to prompt the patient that the required strength of the respiratory muscle set currently has been completed, so as to achieve the purpose of facilitating the device to adjust the strength when exercising the respiratory muscle strength of the patient.

[0023] Through the cooperation of structures such as an installation frame, a connecting fan, and a first connecting rod, the device of the present invention enables the device to rotate the connecting fan when the patient exhales and the air flow passes through the first air duct and then through the connecting fan, and drives the connecting fan to rotate through the shape of the connecting fan, so that the connecting fan drives the first connecting rod and the fixed rolling ring to rotate, causing the roller to contact the convex stripes provided on the outer wall of the first air duct. After the contact, the third return spring contracts the roller, and after passing through the convex stripes, it is reset. By repeating this operation, the first air duct generates vibrations, causing the air to vibrate inside the first air duct. When the patient practices inhaling, the gas enters the patient's lungs and generates vibrations, and the vibrating gas can disperse the sputum when it contacts the sputum, thereby clearing the sputum accumulated in the patient's lungs, so as to achieve the purpose of facilitating the breathing function exercise of the device while clearing the sputum in the patient's lungs.

[0024] Through the cooperation of structures such as a filter cover, a first return spring, and a limiting ball, when different patients use the device to exercise the breathing function, the device of the present invention enables the entire filter cover to be removed to prevent infection. Press the filter cover into the mouthpiece, so that when the limiting ball contracts and is located at the top of the limiting groove, the first return spring resets the limiting ball, thereby limiting the filter cover. When removing, just pull it out forcefully, so as to achieve the purpose of making it more hygienic for patients to use the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] As Figures 1 to 9 shown, the exercise mechanism 4 includes a first air duct 401, a second air duct 402, and an air blocking ball 403. The first air duct 401 is fixed inside the box body 1.

[0043] As Figures 1 to 9As shown in the figure, the sound generating mechanism 5 includes a whistle seat 501, a whistle plug 502 and a whistle opening 503. The whistle seat 501 is arranged at the bottom end of the first air duct 401. A whistle plug 502 is fixed inside the whistle seat 501.

The top end of the whistle seat 501 is snap-connected to the cover plate 7. The outer wall of the piston disc 504 is close to the inner wall of the whistle seat 501. The piston disc 504 is slidably connected to the whistle seat 501. The connecting rope 505 is slidably connected to the whistle seat 501. The connecting rope 505 is slidably connected to the cover plate 7.

[0044] As Figures 1 to 9 shown in the figure, a second return spring 506 is fixed to the outside of the piston disc 504. A gas blocking plate 507 is arranged at the top end of the cover plate 7. The second return spring 506 is used to squeeze the piston disc 504 and keep it in a moving trend towards the whistle opening 503.

[0045] Adopting the above scheme: By integrally installing the whistle seat 501 on the first air duct 401, a whistle sound can be emitted when a child patient exhales, thereby improving the attention and interest of the child patient, and enabling the child patient to use the device to exercise the respiratory function more actively. Further, by pulling the connecting rope 505 and through the reset of the second return spring 506, the position of the piston disc 504 can be changed, thereby changing the sound of the whistle and improving the interest of the child patient when using it.

[0046] As Figures 1 to 9 shown in the figure, the vibration mechanism 6 includes a mounting frame �01, a connecting fan �02 and a first connecting rod �03. The mounting frame �01 is fixed inside the first air duct 401. A connecting fan �02 is movably connected inside the mounting frame �01. A first connecting rod �03 is fixed to the outside of the connecting fan �02. A reinforcing rod �04 is fixed to the outside of the first connecting rod �03. A rolling ring �05 is movably connected to the outside of the first connecting rod �03. A third return spring �06 is fixed to the outside of the rolling ring �05. A roller �07 is fixed to the top end of the third return spring �06. A convex pattern �08 is fixed to the outer wall of the first air duct 401. The inner wall of the mounting frame �01 is close to the outer wall of the connecting fan �02. The mounting frame �01 and the connecting fan �02 are rotatably connected. A number of groups of the third return springs �06 are provided. The third return springs �06 are equidistantly distributed about the central axis of the rolling ring �05. The third return springs �06 are used to squeeze the third return springs �06 and keep them in a moving trend outwards. A number of groups of the convex patterns �08 are provided. The convex patterns �08 are equidistantly distributed about the central axis of the first air duct 401.

[0047] Adopting the above solution: when the patient exhales, the air flow passes through the first air duct 401 and then through the connecting fan 602. The shape of the connecting fan 602 drives the connecting fan 602 to rotate, so that the connecting fan 602 drives the first connecting rod 603 and the fixed rolling ring 605 to rotate, making the roller 607 contact the convex stripes 608 arranged on the outer wall of the first air duct 401. After the contact, the third return spring 606 contracts the roller 607, and after passing through the convex stripes 608, it is reset. Repeating this operation repeatedly makes the first air duct 401 vibrate, causing the air to vibrate inside the first air duct 401. Then, when the patient practices inhaling, the gas enters the patient's lungs and makes a vibration, and the vibrating gas can disperse the sputum when it contacts the sputum, thereby clearing the sputum accumulated in the patient's lungs.

[0048] The working principle and usage process of the present invention: By opening the cover plate 7, the whistle seat 501 and the air-blocking plate 507 can be replaced. And by rotating the screw rod 13, the position of the support disk 12 can be adjusted, thereby changing the distance between the second connecting rod 9 and the support disk 12 and the restoring force of the fifth return spring 11, and changing the overall respiratory muscle exercise of the device. When different patients use the device to exercise their respiratory function, the filter cover 301 can be completely removed to prevent infection. Press the filter cover 301 into the mouthpiece 2. When the limiting ball 303 contracts and is located at the top of the limiting groove 304, the first return spring 302 resets the limiting ball 303, thereby limiting the filter cover 301. When removing, just pull it out forcefully. And when the patient exhales, the air flow enters the inside of the first air duct 401 and pushes up the second air duct 402. By controlling the magnetic force between the second electromagnet 405 and the first electromagnet 404, the air flow rate during breathing can be adjusted. And by setting two groups of air-blocking components, the respiratory muscle strength of the patient can be effectively exercised. And after the first electromagnet 404 and the second electromagnet 405 come into contact, the signal indicator light 14 emits a bright light to prompt the patient that the required strength of the respiratory muscle set currently has been completed. When a child patient uses it to exercise the respiratory function, by installing the whistle seat 501 as a whole on the first air duct 401, a whistle sound can be emitted when the child patient exhales, thereby improving the attention and interest of the child patient, and making the child patient use the device to exercise the respiratory function more actively. Further, by pulling the connecting rope 505 and through the reset of the second return spring 506, the position of the piston disk 504 can be changed, thereby changing the sound of the whistle and improving the interest of the child patient when using it. Furthermore, when an adult patient exercises the respiratory function, by removing the whistle seat 501 as a whole and replacing it with the air-blocking plate 507, noise can be avoided. And when the patient exhales, the air flow passes through the connecting fan 602 after passing through the first air duct 401, and drives the connecting fan 602 to rotate through the shape of the connecting fan 602, so that the connecting fan 602 drives the first connecting rod 603 and the fixed rolling ring 605 to rotate, making the roller 607 contact the convex stripes 608 provided on the outer wall of the first air duct 401. After contact, the third return spring 606 contracts the roller 607, and after passing through the convex stripes 608, it is reset. Repeating this operation repeatedly makes the first air duct 401 vibrate, making the air vibrate inside the first air duct 401. Then when the patient practices inhaling, the gas enters the patient's lungs and emits vibrations, and the vibrating gas can disperse the sputum when contacting the sputum, thereby clearing the sputum accumulated in the patient's lungs. When a child patient exercises the respiratory function, the pressure of exhalation can be changed by adjusting the magnetic force between the first electromagnet 404 and the second electromagnet 405. By reducing the magnetic force of the second electromagnet 405, the force of the first electromagnet 404 being squeezed becomes smaller. At this time, the air pressure when the child patient exhales can be adapted.Moreover, it can gradually increase the required blowing air pressure by gradually increasing the magnetic force, thereby playing a role in exercising the patient's breathing function. The magnetic force of the electromagnet is proportional to the current intensity passing through it. The greater the current, the stronger the generated magnetic field and the greater the magnetic force. By adjusting the current size, the size of the required air pressure can be quickly adjusted. And a display screen is installed at the top of the box body 1, which can display the number of exhalations required for exercise and the size of the exhalation pressure. When the patient uses the device to exhale, the display screen is flipped so that the patient can more conveniently observe the display screen. The display screen can display the data on its surface for the patient to observe to judge the progress of the breathing function exercise.
