[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides an interface structure for a breathing trainer, including a connecting tube 1 and an adjustment interface 2. The adjustment interface 2 includes several ball heads 31, connecting tubes 32, and ball seats 33. The ball heads 31, connecting tubes 32, and ball seats 33 are all hollow structures. The connecting tubes 32 are used to communicate with the ball heads 31 or with the ball seats 33. Both the ball seats 33 and the ball heads 31 have openings 331. The ball heads 31 enter the ball seats 33 through the openings 331 and are hinged. The ball heads 31, connecting tubes 32, and ball seats 33 are sequentially connected to form the adjustment interface 2. One end of the adjustment interface 2 is connected to the connecting tube 1 through the connecting tubes 32, and the other end of the connecting tubes 32 is a free end.

[0023] In this application, when the angle of the adjustment interface 2 needs to be adjusted, the connecting tube 32 is bent, causing relative movement between the ball head 31 and the ball seat 33. This automatically adapts to changes in angle until it is adjusted to a suitable angle for the patient, allowing the patient to maintain the correct posture, fully exhale air, and improve training efficiency. Specifically, there are two ball interfaces. The two ball interfaces are hinged together, providing a larger rotation angle and multiple degrees of freedom, enabling flexible rotation within a more complex angle range and accommodating more precise angle adjustments.

[0024] In one feasible embodiment, a first receiving groove 332 is formed on the inner peripheral wall of the ball seat 33. The first receiving groove 332 is used to place a first sealing ring 333, which abuts against the outer peripheral wall of the ball head 31. In this embodiment, the first sealing ring 333 helps to keep the ball seat 33 clean by preventing dust and other contaminants from entering the interior of the ball seat 33. In addition, the interface structure of this application needs to maintain the airtightness between the ball head 31 and the ball seat 33 to prevent gas from flowing out from the gap between the ball head 31 and the ball seat 33 during the patient's exhalation.

[0025] In one feasible embodiment, an adjusting screw 334 is also threaded onto the ball seat 33. The free end of the adjusting screw 334 extends into the ball seat 33 and abuts against the ball head 31. The free end of the adjusting screw 334 is flexible. In this embodiment, the flexible free end of the adjusting screw 334 can press against the outer peripheral wall of the ball head 31. Furthermore, by turning the adjusting screw 334, the friction between the adjusting screw 334 and the ball joint can be adjusted. This adjusted friction facilitates movement while also fixing the ball head 31 and the ball seat 33 at the desired angle.

[0026] When the adjusting screw 334 is tightened, the friction between the adjusting screw 334 and the ball joint increases; conversely, loosening the screw reduces friction.

[0027] In one feasible embodiment, the adjusting screw 334 is closer to the opening 331 than the sealing ring. In this embodiment, gas leakage from the threaded connection between the adjusting screw 334 and the ball seat 33 can be effectively prevented, maintaining the seal between the ball head 31 and the ball seat 33.

[0028] In one feasible embodiment, the connecting cylinder 1 is provided with a limiting plate 4 and a movable plate 5. The limiting plate 4 is fixed inside the connecting cylinder 1 and has a through hole 41. The limiting plate 4 is located above the connection between the connecting cylinder 1 and the adjustment interface 2. The movable plate 5 is movably disposed inside the connecting cylinder 1 and located above the limiting plate 4. The connecting cylinder 1 is provided with an elastic element 6, which is used to drive the movable plate 5 to abut against the limiting plate 4. This embodiment adopts the basic principle of resistance training. The patient blows air from the adjustment interface 2 and needs to exert effort to resist the resistance set by the movable plate 5 and the elastic element 6 to increase the blowing muscle strength, thereby increasing the strength and endurance of the respiratory muscles. Specifically, the patient exhales air from the free end of the adjustment interface 2, the air enters the connecting cylinder 1 from the adjustment interface 2, and the air overflows from the through hole 41, pushing the movable plate 5 upward. The elastic element 6 has a reaction force on the movable plate 5, and the patient needs to exhale a larger airflow to resist the above-mentioned reaction force, thereby achieving a better training effect.

[0029] Specifically, the elastic element 6 is a spring, and a stop plate 7 is detachably connected to the end of the connecting cylinder 1. The stop plate 7 is located above the moving plate 5, and the stop plate 7 has an air hole 71. One end of the spring abuts against the moving plate 5, and the other end abuts against the stop plate 7. The air hole 71 can discharge or draw gas into the connecting cylinder 1 during the movement of the moving plate 5, maintaining the atmospheric pressure inside the connecting cylinder 1 in balance with the external atmospheric pressure. In this embodiment, the stop plate 7 and the connecting cylinder 1 are detachably connected by a threaded connection. By disassembling the stop plate 7 and replacing it with a spring with a different elastic coefficient, targeted training can be performed.

[0030] In one feasible embodiment, a guide rod 51 protrudes from the side of the movable plate 5 away from the limiting plate 4. The guide rod 51 extends along the central axis of the connecting cylinder 1 through the air hole 71 to the outside of the connecting cylinder 1, and the spring is sleeved on the outer periphery of the guide rod 51. In this embodiment, the guide rod 51 can prevent the spring from coming out.

[0031] In one feasible implementation, the diameter of the vent 71 is larger than the diameter of the guide rod 51, thereby preventing friction between the guide rod 51 and the vent 71, which would affect the movement of the moving plate 5. Furthermore, gas can escape from the gap between the guide rod 51 and the vent 71, thus maintaining air pressure balance.

[0032] In one feasible embodiment, the movable plate 5 is provided with a second receiving groove 52, which is used to place a second sealing ring 53, which abuts against the inner peripheral wall of the connecting cylinder 1. In this embodiment, the second sealing ring 53 can prevent the patient's exhaled gas from leaking out from the gap between the movable plate 5 and the inner wall of the connecting cylinder 1, ensuring that the force on the elastic element 6 is consistent with the preset value, and ensuring that the preset training effect is achieved.

[0033] In one feasible embodiment, a sealing plate 8 is detachably connected to the end of the connecting cylinder 1, and the sealing plate 8 is located below the limiting plate 4. The sealing plate 8 and the connecting cylinder 1 are detachably connected by a threaded connection. During the patient's exhalation, saliva can enter the connecting cylinder 1 through the adjustment port 2, causing contamination inside the connecting cylinder 1. The interior of the connecting cylinder 1 can be cleaned by removing the sealing plate 8, maintaining the hygiene of the interior of the connecting cylinder 1.
