In addition, the structures of the floating channel 211 and the circulation channel 13 are regular, and they are also convenient for processing and manufacturing.

[0057] In other embodiments of the present application, Figure 3 As shown, there are multiple float mechanisms 20, and the multiple float mechanisms 20 are distributed in sequence along the direction from the first end to the second end.

[0058] The direction from the first end to the second end may refer to the length direction of the body 10. Figures 1 to 3 The direction indicated by the arrow M.

[0059] By adopting the technical solution of this embodiment and providing multiple float mechanisms 20, multiple floats 22 are allowed to float during the training process, thereby increasing the fun of the training and making it easier for patients, especially child patients, to accept the training.

[0060] In other embodiments of the present application, Figure 3 As shown, the floats 22 in the plurality of float mechanisms 20 have different colors.

The airflow sensor 31 is arranged in the circulation channel 13, and the airflow sensor 31 is used to detect the flow direction of the airflow in the circulation channel 13; the sound-emitting component 32 is communicatively connected with the airflow sensor 31, so that when the airflow sensor 31 detects that the airflow in the circulation channel 13 flows into the circulation channel 13 from the air outlet 12, the sound-emitting component 32 can make a sound.

[0063] The airflow sensor 31 may refer to a sensor capable of detecting the flow direction of airflow. The airflow sensor 31 may be, but is not limited to, a hot wire sensor, a wind speed sensor, a differential pressure sensor, and a vibration sensor.

[0064] The sound-emitting component 32 may refer to a component that can emit sound, such as a buzzer or a speaker.

[0065] The sounding piece 32 and the airflow sensor 31 can be connected via wires, wireless communications, etc., that is, when the airflow sensor 31 detects that gas flows from the air outlet 12 into the flow channel 13, the signal emitted by the airflow sensor 31 can control the sound of the sounding piece 32, thereby reminding the patient to exhale through the nose.

[0068] The whistle 33 may refer to a component for producing a sharp whistle. When exhaling into the whistle 33, air flows through the tube, producing a sharp whistle. The whistle 33 may be, but is not limited to, a coach whistle, a police whistle, a referee whistle, or a children's whistle. The whistle 33 may be a mature whistle product on the market, and its specific structure will not be described in detail here.

[0069] The inlet of the whistle 33 may refer to the airflow inlet when the whistle 33 makes a whistle sound. The airflow is connected to the circulation channel 13 and is arranged toward the air outlet 12, so that the gas flowing into the circulation channel 13 from the air outlet 12 can enter the inlet of the whistle 33, thereby blowing the whistle 33 to make a whistle sound, reminding the patient to exhale through the nose.

[0070] By adopting the technical solution of this embodiment, the whistle 33 has a simple structure, is easy to obtain, and is low in cost, which is conducive to reducing the production cost of the atomization inhalation training device 100.

[0071] In other embodiments of the present application, Figure 4 As shown, the air flow channel 331 of the whistle 33 is arranged obliquely relative to the flow channel 13 , and the air flow channel 331 of the whistle 33 is located at a side of the inlet of the whistle 33 facing away from the air outlet 12 .

[0072] The air flow channel 331 of the whistle 33 may refer to the channel through which the air flows in the whistle 33 when the whistle 33 makes a whistle sound, and the air flow channel 331 is inclined relative to the circulation channel 13, and the air flow channel 331 is located on the side of the inlet of the whistle 33 that is away from the air outlet 12, so that the air flow channel 331 can follow the flow direction of the gas exhaled from the patient's mouth, and the gas exhaled from the mouth can enter the whistle 33, thereby blowing the whistle 33; in addition, the air flow channel 331 is opposite to the flow direction of the gas exhaled from the patient's mouth, so that the air flow flowing from the circulation channel 13 into the air outlet 12 is not easy to enter the whistle 33, thereby reducing the risk of accidentally blowing the whistle 33 to achieve a better training effect.

[0073] For example, see Figure 4 As shown, the whistle 33 is installed on the lower side of the body 10 , and the whistle 33 extends obliquely downward in the direction from the air outlet 12 to the air inlet 11 .

[0074] By adopting the technical solution of this embodiment, the probability of the whistle 33 being blown by mistake can be reduced, which is beneficial to improving the training effect.
