1. A respiratory ventilation device, intended to send an air flow, generated by a fan, into a duct, the duct extending between the device and a respiratory mask, intended to be worn by a user, the device extending between a lower end, forming a bottom, and an upper end, the device having:
a ventilation chamber, containing the fan; and
a humidifier, connected to the ventilation chamber, and intended to humidify the air blown in by the fan, the humidifier having a water reservoir intended to accommodate water;
the humidifier having:
a connecting chamber, adjacent to the ventilation chamber, and comprising:
an intake opening, leading out of the ventilation chamber; and
an exhaust opening, leading into an exhaust channel, the exhaust channel being configured to be attached to the duct;
a humidification chamber, having the water reservoir; and
a first opening and a second opening, separate from one another, formed between the connecting chamber and the humidification chamber;
wherein:
the connecting chamber extends between the humidification chamber; and the ventilation chamber; and
the device has a separating wall extending between the connecting chamber and the humidification chamber, the first opening and the second opening being made in the separating wall, the separating wall being arranged such that:
the humidification chamber extends between the bottom and the separating wall; and
the connecting chamber extends between the separating wall and the ventilation chamber.
