Abstract
A noise-reducing air passage device and its components for use in ventilator systems, including a housing with at least one inlet, at least one outlet, an inner wall, and an outer wall. The space enclosed by the inner wall of the housing forms a gas passage including at least one chamber to provide a space for gas accumulation and flow. A blower, the core component to provide positive pressure gas to the device, is secured within one of the at least one chamber. The gas passage also includes a ventilation component to divide the gas and streamline turbulent airflow. The ventilation component is among the noise-reducing components, which also include a support component to provide support and damp vibrations for the blower and an inlet component provided at the inlet.
