A power supply control device and a ventilating device using the same. The ventilating device includes a blower system (12) and the power supply control device for supplying power to the blower system (12). The power supply control device includes a power supply and a switching control system (7). The power supply includes a solar power supply unit (1) and an electric network power supply unit (4), and the switching control system (7) is in control of switching between the solar power supply unit (1) and the electric network power supply unit (4). The solar power supply unit (1) comprises solar cells (2) and a DC-DC boosting circuit (3), an input terminal of the DC-DC boosting circuit (3) is connected to an output terminal of the solar cells (2), and an output terminal of the DC-DC boosting circuit (3) supplies power to the exterior. The electric network power supply unit (4) comprises an AC-DC rectifying circuit (6), an input terminal of the AC-DC rectifying circuit (6) is connected to an electric network alternating current input (5), and its output terminal supplies power to the exterior. |
