[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model proposes a breathing training device, see reference. Figure 1 , 4 The device includes a training body 1, which contains an air inlet chamber 11 and a control chamber 13. The air inlet chamber 11 has an air outlet 12, allowing the user to blow air into it. The control chamber 13 has an air inlet 131 on its side wall, which connects it to the air inlet chamber 11. One end of the control chamber 13 has an opening 132, which connects it to the outside. The other end of the control chamber 13 has several air outlets 133. The airflow path within the training device is: air outlet → air inlet chamber → air inlet → control chamber → air outlet.

[0024] See Figure 2 , 4 A control knob 2 is rotatably connected to the control chamber 13. The control knob 2 is located below the opening 132, and a portion of the peripheral wall of the control knob 2 is provided with an air inlet groove 21. The control knob 2 cuts off the airflow path from the air inlet 131 to the control chamber 13. This product adjusts the expiratory resistance of the trainer by changing the number of air inlets 21 connected to the air inlet 131. Specifically, when the number of connected air inlets 21 increases, the airflow path increases, and the resistance of the airflow in the air inlet chamber 11 entering the control chamber 13 decreases, thus reducing the expiratory resistance of the breathing trainer. Conversely, when the number of connected air inlets 21 decreases, the expiratory resistance of the breathing trainer increases. Users can adjust the resistance of the trainer by rotating the control knob 2, making operation simpler.

[0025] See Figure 1 The control knob 2 has a rotating boss 22 at its end, which extends out of the opening 132. The rotating boss 22 has several anti-slip grooves 221 on its peripheral side, allowing the user to rotate the control knob 2 more conveniently by rotating the boss 22.

[0026] See Figure 2 , 3The training device body 1 includes an upper shell 14 and a lower shell 15 that are spliced ​​together. An opening 132 is provided in the upper shell 14. A sealing annular protrusion 141 is provided below the opening 132. An air inlet 131 is provided on the sealing annular protrusion 141. A connecting annular protrusion 151 is provided inside the lower shell 15. An air outlet 133 is provided on the bottom surface of the inner cavity of the connecting annular protrusion 151. The sealing annular protrusion 141 and the connecting annular protrusion 151 are interlocked to form the control cavity 13.

[0027] See Figure 2 The air intake chamber 11 is provided with two air guide plates 16 spaced apart, and an air guide channel 161 is formed between the air guide plates 16. The two ends of the air guide channel 161 are respectively connected to the air blowing port 12 and the air intake port 131. The air guide channel 161 allows the airflow blown out by the user to flow to the control chamber 13 to ensure the effectiveness of breathing training.

[0028] See Figure 2 , 4 The outer side of the air inlet 12 is provided with a positioning annular protrusion 17, and a support sleeve 18 is inserted into the positioning annular protrusion 17. The support sleeve 18 is provided with a clearance hole 181, which communicates with the air inlet 12. The user can bury their face in the support sleeve 18 for breathing training.

[0029] See Figure 3 The air intake groove 21 only extends through the other end of the control knob 2. The air intake groove 21 is not connected to the end with the rotating boss 22. The length of the air intake groove 21 is wider than the air inlet 131, thereby ensuring that the airflow entering through the air intake groove 21 flows to the air outlet 133, so as to improve the effectiveness of breathing training.

[0030] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
