[0021] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0022] Example

[0023] A breathing training device described in this embodiment, such as Figures 1 to 5 As shown, it includes an air cylinder 1, in which an active ball 5 is arranged, a spring 4 is installed between the active ball 5 and the bottom of the air cylinder 1, and an air outlet hole for gas discharge is opened on the air cylinder 1. This section as a whole constitutes a training component for breathing training. When in use, the patient's exhalation acts on the active ball 5, breaking through the elastic force of the spring 4 to make the active ball 5 move to the left along the air cylinder 1, and the gas exhaled by the patient is discharged from the air outlet hole; in addition, the bottom of the air cylinder 1 is provided with a mounting hole that communicates with the inside and outside, and a detachable end cover 3 is installed in the mounting hole, one end of the spring 4 is connected to the end cover 3, and the other end thereof rests on the active ball 5; the end cover 3 is connected to the left end (bottom of the air cylinder 1) by a thread, and the diameter of the mounting hole when it is opened is equal to the inner diameter of the air cylinder 1; when in use, by disassembling the end cover 3, the spring 4 can be replaced in special circumstances. There are three air outlets, which are evenly spaced along the length of the air cylinder 1. When the activity ball 5 moves to the left, each time the activity ball 5 passes through an air outlet, the air outlet will disperse a part of the patient's exhaled gas. In this way, the patient needs to exhale more gas to make the activity ball 5 continue to move to the left, so as to achieve the purpose of step-by-step breathing training. The three air outlets correspond to three levels. The outer wall of the air cylinder 1 is connected with an air outlet duct 2 that connects all the air outlets. One end of the air outlet duct 2 is in a closed state. The gas discharged from the air outlet is guided by the air outlet duct 2 and uniformly discharged from the outlet of the air outlet duct 2. The outlet of the air outlet duct 2 is close to the left end of the air cylinder 1, and the other end is in a closed state. The activity ball 5 is a hollow structure and is made of plastic material. It is light in texture and more conducive to movement. There is a small gap between the surface of the activity ball 5 and the inner wall of the air cylinder 1.

[0024] The air inlet end of the air cylinder 1 is connected to a regulating valve, and the other end of the regulating valve is connected to a blowing nozzle 6 which is in communication therewith; when in use, the patient exhales through the blowing nozzle 6, and the gas enters the air cylinder 1 after passing through the regulating valve.

[0025] like Figure 1As shown, the regulating valve includes a valve body 8, the outer surface of the valve body 8 is a cylindrical structure, flush with the outer side wall of the air cylinder 1, and the overall structure is beautiful; the valve body 8 is connected to the air inlet end of the air cylinder 1 through a thread, and the left end of the valve body 8 is connected to a first threaded cylinder, and the outer side wall of the first threaded cylinder is provided with a first external thread, and the inner side wall of the air inlet end of the air cylinder 1 is provided with a first internal thread that is threadedly matched with the first external thread. A cavity with a spherical structure is provided in the valve body 8, and a freely rotating ball valve 7 is provided in the cavity. The spherical surface of the ball valve 7 fits with the inner wall of the cavity, and a plurality of air holes with different diameters passing through the ball valve 7 are provided on the ball valve 7; there are four air holes in this embodiment, and the diameters of the four air holes are arranged in sequence from small to large; the center lines of all the air holes are in the same plane and intersect at the center of the ball, and the center lines of the air holes are distributed at equal intervals along the circumference of the ball valve 7; a vent hole is provided on the valve body 8 to connect the blowing nozzle 6 with the air cylinder 1, the vent hole and the center lines of all the air holes are in the same plane, and the center line of the vent hole and the center of the ball valve 7 are in the same straight line, and a rotating shaft 10 is fixed on the spherical surface of the ball valve 7, and a through hole for the rotating shaft 10 to pass through is provided on the valve body 8, and one end of the rotating shaft 10 independently passes through the through hole and is connected to an adjusting disk 9, and the adjusting disk 9 is located on the outside of the valve body 8; the center line of the rotating shaft 10 is in the same straight line with the center of the ball valve 7 and is perpendicular to the center lines of all the air holes.

[0026] like Figure 5As shown, scale lines are provided on the adjustment disk 9 at both ends of each pore, and the same number is provided on the adjustment disk 9 for the two symmetrical scale lines. This section as a whole constitutes an identification component corresponding to each pore; the two corresponding scale lines correspond to the two ends of a pore, so the numbers of these two scale lines are connected. During production, the pore with the smallest diameter corresponds to "number 1", and then "number 2, number 3, number 4" correspond to the pore with the largest diameter in turn. Rotating the adjustment disk 9 can drive the ball valve 7 to rotate through the rotating shaft 10, and the pores with different diameters are connected to the vents to control the size of the airflow through the channel, so as to achieve the purpose of adjusting the breathing training. A connecting seat 11 is fixed on the outer wall of the valve body 8, and a through hole passes through the connecting seat 11. The adjusting disk 9 is located on the outer side of the connecting seat 11 and fits with it. The rotating shaft 10 passes through the connecting seat 11 and is connected to the center of the adjusting disk 9. During production, the connecting seat 11 and the valve body 8 are integrally formed. The through hole is opened on the valve body 8 and passes through the connecting seat 11. The connecting seat 11 is cylindrical as a whole, which mainly fills the gap between the adjusting disk 9 and the outer wall of the valve body 8 to increase the overall aesthetics. In addition, a rubber can be set between the through hole and the rotating shaft 10. A rubber sealing ring is provided to increase the air tightness of the structure; an indicating arrow is provided on the outer side wall of the connecting seat 11 corresponding to the vent hole; the indicating arrow represents the position of the vent hole, and the scale line represents the position of the vent hole. When in use, for example, when the scale line corresponding to "No. 1" is aligned with the indicating arrow, it means that the vent hole corresponding to the scale line is connected with the vent hole, that is, the vent hole of "No. 1" is connected with the vent hole, and in addition, by rotating the adjusting disk 9, other vent holes are also controlled to be connected with the vent holes, and the aperture of the vent hole is larger than the aperture of the largest vent hole.

[0027] like Figure 5 As shown, during production, the valve body 8 is divided into two equal parts, the ball valve 7 is fixed to the rotating shaft 10, and then the ball valve 7 is placed in the spherical cavity. After that, the separated ball valve 7 is connected and sealed by adhesive. The ball valve 7 fits the inner wall of the spherical cavity to prevent air leakage. The blowing nozzle 6 is connected to the right end of the valve body 8 by a thread. The blowing nozzle 6 is connected to a second threaded barrel, and a second external thread is provided on the outer wall of the second threaded barrel. A second internal thread that is threadedly matched with the second external thread is provided on the inner wall of the right end of the valve body 8, so that the blowing nozzle 6 and the valve body 8 are detachably connected. When cleaning, the valve body 8, the air cylinder 1 and the blowing nozzle 6 can be disassembled separately to facilitate cleaning of the interior.

[0028] like Figure 4 As shown, the overall appearance and structure are simple and straight, which is convenient to carry with you. You can take it out and do breathing training anytime and anywhere in your spare time.

[0029] In actual use, the patient holds the blowing nozzle 6 and exhales, and the air flow enters the air cylinder 1 through the regulating valve, breaking through the restriction of the spring 4 to move the movable ball 5 to the left, so as to achieve the purpose of breathing training. In this process, the size of the air flow passage space in the valve body 8 can be controlled by rotating the adjusting disk 9. When the "number 1" air hole is opposite to the vent hole, the air flow channel is the smallest and the resistance is the largest. The patient needs to exhale more air to make the movable ball 5 move to the left. By analogy, when the "number 4" air hole is opposite to the vent hole, the air flow channel is the largest, and it is easy to make the movable ball 5 move to the left. This embodiment is divided into four different gears. According to the different needs of the patient, the adjusting disk 9 can be rotated to make the scale lines of different gear numbers opposite to the indicating arrows, so as to accurately control the size of the air flow passage of the valve body 8 and divide different gears. During the breathing training process, the patient can adjust to the same gear as the previous training for the next training. At the same time, according to the patient's recovery, the gear is changed step by step to standardize the breathing training.
