In the air flow regulating mechanism 13, there are two working states of an exhalation state and an inhalation state, in the initial state of the air flow regulating mechanism 13, the upper and lower electromagnetic generators 1306 control the magnetic force to make the electromagnetic slider 1308 be located in the middle position of the air cavity sliding barrel 1301, when the air flow induction controller 11 at the rear side detects the air flow, the exhalation working state is switched, the electromagnetic generators 1306 control the magnetic force to make the electromagnetic slider 1308 actively slide downwards to provide the exhalation assisting force for the starting stage of the patient exhalation, the balance height of the electromagnetic slider 1308 subjected to the magnetic force is the height of the upper end of the second spring 1309, the subsequent air flow continuously enters the air cavity sliding barrel 1301 from the exhalation air inlet 1304, the air flow increases the air pressure in the air cavity sliding barrel 1301, the air pressure makes the electromagnetic slider 1308 continuously slide downwards, the second spring 1309 is compressed to provide the upward thrust force for the electromagnetic slider 1308, the balance height is achieved by the air pressure and the elastic force of the second spring 1309, after the expiration is finished, the airflow is no longer detected by the airflow sensing controller 11 on the rear side, the electromagnetic generator 1306 controls the magnetic force to make the electromagnetic slider 1308 return to the initial state, if the airflow is still detected by the airflow sensing controller 11 on the front side after the electromagnetic slider 1308 returns to the initial state, it is proved that the patient is still inhaling, the electromagnetic generator 1306 continues to control the magnetic force to make the electromagnetic slider 1308 actively slide upwards, the upward sliding process after the upward sliding resetting and the upward sliding process after the resetting of the electromagnetic slider 1308 provide the active force for the beginning stage of the inspiration process of the patient, so that the inspiration process of the patient after the expiration is smoothly switched, because the pressure of the expired gas is greater than the pressure of the inspired gas, the upward magnetic force applied to the electromagnetic slider 1308 during the inspiration is greater than the downward magnetic force applied during the expiration, and the magnitude of the excess magnetic force is balanced by the second spring 1309 on the upper side, therefore, the electromagnetic slider 1308 can move upwards for a short distance, so that the resistance in the inspiration process is not too large, the cavity air pressure variation above the electromagnetic slider 1308 needs to be kept larger than that below the electromagnetic slider, the upward height of the electromagnetic slider 1308 does not exceed the middle height of the inspiration air outlet 1303 and the expiration air inlet 1304, the adjustment of the size of the inspiration resistance is realized by adjusting the magnetic force balance position, meanwhile, the electromagnetic slider 1308 can move upwards for a certain distance under the pulling of lower upper air pressure, the upward pulling force of the air pressure is balanced by the second spring 1309 on the upper side, after the inspiration process is completed, the air flow is not detected by the air flow induction controller 11 on the front side, the electromagnetic generator 1306 controls the magnetic force to restore the electromagnetic slider 1308 to the initial state, and the breathing exercise of a patient is realized by repeating the breathing process.
Because the water vapor generated by the patient during breathing is condensed on the inner wall of the air cavity sliding barrel 1301, in order to prevent the condensed water vapor from affecting the sliding of the electromagnetic slider 1308 and the parts in the device, the electromagnetic slider 1308 cooperates with the water vapor collecting component to remove the water vapor condensed on the inner wall of the air cavity sliding barrel 1301, since the outside air is sucked during inhalation without generating moisture, by sliding the electromagnetic slider 1308 upward during inhalation, the water vapor generated in the exhalation process is cleaned, the concave part on the upper surface of the electromagnetic slider 1308 is matched with the diversion trench, the water vapor on the inner wall of the air cavity sliding barrel 1301 is scraped and collected in the concave part of the electromagnetic slider 1308, after the electromagnetic slider 1308 is moved to the upper part of the fixed slide bar 1307, the liquid collected in the depression of the electromagnetic slider 1308 flows into the fixed slide bar 1307 through the collection port on the fixed slide bar 1307, and the collected liquid flows down into the moisture collection assembly through the hollow fixed slide bar 1307.
