[0025] Similarly, when performing inhalation training, the air outlet port 12 can be closed, and the user can inhale external air into the lungs through the mouthpiece 22.

[0028] Further, in this embodiment, as an implementation scheme of the air intake regulating valve 31, the air intake regulating valve 31 includes a first connecting seat 311 and a rotating baffle 312, the first connecting seat 311 is provided with a first air inlet 3111, and the rotating baffle 312 is provided with a second air inlet 3121, the first connecting seat 311 is connected to the air intake port 11, the rotating baffle 312 is provided between the first connecting seat 311 and the air intake port 11, and can rotate relative to the first connecting seat 311, specifically, the first connecting seat 311 is provided with a gear slot 3112, and the rotating baffle 312 is provided with a lever 3122, and the lever 3122 passes through the gear slot 3112 to drive the rotating baffle 312 to rotate.

[0029] Through the above-mentioned arrangement, the user can move the lever 3122 to move it in the gear slot 3112, so as to drive the rotating baffle 312 to rotate relative to the first connecting seat 311, thereby controlling the relative position of the second air inlet 3121 and the first air inlet 3111. When the rotating baffle 312 rotates until the second air inlet 3121 completely overlaps with the first air inlet 3111, the air inlet port will be fully opened. Continue to rotate the rotating baffle 312. At this time, the rotating baffle 312 will partially block the first air inlet 3111, thereby adjusting the opening and closing size of the first air inlet 3111 to achieve the adjustment of the air intake volume. Furthermore, in this embodiment, a gear number is correspondingly arranged on the gear slot 3112 to mark the opening and closing gear of the first air inlet 3111.

It can be understood that in the present embodiment, the size of the second air outlet 3221 matches the maximum size of the first air outlet 3211.

[0031] Through the above arrangement, the user can rotate the rotating cover 322 so that the second air outlet 3221 passes through different first air outlets 3211. When the second air outlet 3221 coincides with the largest first air outlet 3211, the air outlet volume of the air outlet port 12 reaches a maximum. When the second air outlet 3221 coincides with the smallest first air outlet 3211, the air outlet volume of the air outlet port 12 reaches a minimum, thereby realizing the adjustment of the air outlet volume.

[0032] Furthermore, in this embodiment, a bracket 41 and a vibration ball 42 are disposed below the air outlet port 12 . The bracket 41 is provided with an opening 411 , and the vibration ball 42 is disposed on the bracket 41 .

The differential pressure sensor 13 can accurately test the amount of inhalation this time. When exhaling, the gas in the lungs can be exhaled into the airway main body 1 through the mouthpiece 22, and the gas entering the airway main body 1 can be discharged from the air outlet port 12 through the opening 411. When the gas passes through the opening 411, a force is applied to the vibration ball 42, causing the vibration ball 42 to reciprocate up and down, thereby causing airflow oscillation, forming a The oscillating air pressure is formed to drive the secretions to form resonance, reduce viscosity, and thus promote expectoration. Furthermore, in the above-mentioned expectoration process, the breathing training function can also be achieved by adjusting the air outlet volume and the air inlet volume of the air outlet port 12 and the air inlet port 11. After repeated breathing training for several times, if the sputum is effectively discharged, it means that the amount of air inhaled each time is effective for expectoration. If the sputum cannot be discharged after repeated breathing training for several times, it means that the air inhalation volume cannot meet the needs of expectoration, and the air inhalation volume must continue to be adjusted until the sputum is discharged.

[0034] Furthermore, in the present embodiment, a first one-way valve 51 and a second one-way valve 52 are also provided between the air inlet port 11 and the air outlet port 12.

[0035] Through the above arrangement, when inhaling, a negative pressure is formed in the second main body unit 23, and the gas enters from the lower air inlet port 11. The gas passes through the first support frame 71 to lift the edge of the first one-way valve 51 to achieve the opening of the air inlet port 11. At the same time, under the action of the negative pressure, the second one-way valve 52 will be tightly attached to the second support frame 72 to achieve the closing of the air outlet port 12.

At the same time, under the action of the positive air pressure, the first one-way valve 51 will be tightly attached to the first support frame 71 to achieve the closing of the air inlet port 11. The structure is simple and the arrangement is ingenious.

[0036] Furthermore, in the present embodiment, the multifunctional breathing training device also includes a PCB board 61 and a display screen 62, the airway main body 1 includes an installation port 63, the installation port 63 penetrates the inner wall of the airway main body 1, the differential pressure sensor 13 is arranged in the installation port 63, and is electrically connected to the PCB board 61, and the display screen 62 is electrically connected to the PCB board 61.

In addition, when sputum removal training is required, the second connecting seat 321 can be disassembled and the vibration ball 42 can be placed on the bracket 41.
