[0032] In the embodiment, the control platform 1 is used to control the operation frequency of the linear driving device 2, the control platform 1 feeds back the position detection of the color mark plate 5 through the color mark sensor 4, and then controls the amplitude of the operation of the opening and closing tidal volume mechanism 3 driven by the linear driving device 2. The airflow generated in the operation of the opening and closing tidal volume mechanism 3 is simulated and tested by the breathing machine. The test data are compared with the position detection data of the color mark plate 5 by the color mark sensor 4. In the operation of the opening and closing tidal volume mechanism 3, the color mark sensor 4 moves along the direction of the color mark plate 5, and then detects the positions of different colors on the color mark plate 5, and then obtains the opening and closing amplitude of the opening and closing tidal volume mechanism 3.

[0033] Reference Figure 5 Before the test starts, the test duration, breathing frequency, tidal volume, and breathing ratio are set. After the parameters are set, the test is started. It is judged whether the test duration is reached. If yes, the test is stopped. Otherwise, the test is continued. After starting, the motor is forward rotated to make the sliding block 21 rise and drive one end of the opening and closing tidal volume mechanism 3 to rise and dilate to simulate lung inhalation. When the simulated lung inhalation tidal volume reaches the set value, the motor is reversed to make the sliding block 21 descend and drive one end of the opening and closing tidal volume mechanism 3 to descend and contract to simulate lung exhalation. If the tidal volume is not reached, the motor is continuously forward rotated in the next time, but the number of rotations is more than the preset number of rotations than that in the last time, so that the height of the sliding block 21 is higher, that is, the amplitude of the opening and closing tidal volume mechanism 3 is larger.
