An annular silicone sleeve 13 is provided at the rear end of the air blower 1 to improve the comfort of the air blower 1 when in contact with the mouth and to increase airtightness, preventing air leakage at the contact point between the mouth skin and the air blower 1. An exhaust pipe 2 is sleeved on the front of the air blower 1, and the air blower 1 and the exhaust pipe 2 slide circumferentially at the sleeve joint. A slider 11 is circumferentially provided on the outer surface of the front of the air blower 1, and a slider 11 is circumferentially provided on the inner surface of the rear of the exhaust pipe 2. The sliding groove 21 of block 11 allows the air blower 1 and the exhaust pipe 2 to slide circumferentially through the cooperation of the slider 11 and the sliding groove 21. A screwing part 23 is circumferentially provided on the outer surface of the exhaust pipe 2. Anti-slip protrusions 231 are arrayed circumferentially on the outer surface of the screwing part 23 to prevent slippage between the hand and the contact surface of the screwing part 23 during screwing, thus affecting operation. A gear indicator 232 is provided on the rear side of the screwing part 23. In this embodiment, numbers 0-5 are used to represent different gears. For example, 0 represents that the air outlet 221 is completely covered by the polygonal baffle 41, and numbers 1 to 5 represent that the air volume of the air outlet 221 gradually increases.

[0042] Working principle: During use, rotating the screw 23 controls the position of the polygonal baffle 41 through the cooperation of the linear through groove 222 and the sliding rod 411, thereby adjusting the air volume of the patient's exhaled airflow through the air inlet 121. This allows the exhalation training device to adjust the training intensity during use, improving the patient's training effect. The exhaust pipe 2 contains several colored ribbons 62 with different colors and thicknesses. By adjusting the air volume of the air inlet 121 and using ribbons 62 of different thicknesses for combined training, patients can obtain a variety of training programs with different resistances. The difficulty settings are rich and the operation is highly operable. By observing the height and duration of the ribbons 62 rising, patients can intuitively feel whether the exhalation intensity has reached the standard. Furthermore, the dynamic changes of the ribbons 62 during training increase the fun of training, reduce the boredom of training, and help patients persist in training for a long time.
