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), provided with one or a plurality of air delivery ports (212A, 212B), and a mask ventilation port (211) used for being in communication with the breathing mask (20) a valve assembly (220) arranged at at least one of the air delivery ports (212A, 212B), the valve assembly (220) being matched with the air delivery ports (212A, 212B) to form an air inlet port and an air discharge port, the valve assembly (220) being configured to connect the air inlet port to the mask ventilation port (211) when the pressure (P1) within the cavity (210) is less than or equal to the atmospheric pressure (P0), and connect the air discharge port to the mask ventilation port (211) when the pressure (P1) within the cavity (210) is greater than the atmospheric pressure (P0). The cross-sectional area of the air inlet port is greater than that of the air discharge port, and the air discharge port keeps the pressure (P1) within the cavity (210) greater than the atmospheric pressure (P0) during exhalation. 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 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.Linvention concerne un appareil de commande de ventilation (200), et un dispositif de masque de respiration (20) ayant lappareil de commande de ventilation (200).
