Abstract:
A ventilation device includes a passage unit (100), a wind turbine (200) and a fan (300). The wind turbine (200) is provided above the passage unit (100), and the fan (300) is provided within the wind turbine (200). The rotation of the wind turbine (200) drives the fan (300) to rotate, so that the air within the passage (100) is exhausted by the fan.
