A ventilation control apparatus (200), and a breathing mask device (20) provided with the ventilation control apparatus (200). The ventilation control apparatus (200) comprises a cavity (210) and a valve assembly (220). The cavity (210) is provided with an air delivery port (211) and a mask ventilation port (212) which are in communication with one another, the mask ventilation port (212) being used for being in communication with the breathing mask (20). The valve assembly (220) is provided with an air inlet channel and an air discharge channel in communication with the cavity (210) via the air delivery port (211). The valve assembly (220) is configured to connect the air inlet channel when the pressure (P1) within the cavity (210) is less than or equal to the atmospheric pressure (P0), and connect the air discharge channel when the difference (ΔP) between the pressure (P1) within the cavity (210) and the atmospheric pressure (P0) is greater than or equal to a predetermined value. The ventilation control apparatus (200) implements an exhalation phase positive pressure function, and prevents patient discomfort caused by continuous positive pressure. A positive pressure air supply apparatus (such as a CPAP breathing machine) and a pipeline etc. need not be connected during use, thereby facilitating patient movement, and the positive pressure air supply apparatus need not be carried when going out. A patient may carry the breathing mask (20) provided with the ventilation control apparatus (200) at any time for treatment. In addition, the ventilation control apparatus (200) is small in size, convenient to carry, and low in cost.La présente invention concerne un appareil de commande de ventilation (200), et un dispositif de masque respiratoire (20) muni de lappareil de commande de ventilation (200).
