The present invention relates to a fluid pumping device. The device includes: a pumping casing which includes a space unit inside, an inlet for introducing a fluid to the inside space unit and discharges the fluid in the inside space unit, and a rotational fan which is prepared in a rotatable manner in the inside space unit and selectively opens or closes the inlet and an outlet; a driving motor which generates rotational power using the applied power; and a power delivery unit which delivers the rotational power from the driving motor to the pumping casing and includes one input axis for inputting the rotational power from the driving motor and one output axis for delivering the rotational power delivered through the input axis to the rotational fan of the pumping casing. According to the present invention, by stably delivering the rotational power from the driving motor to the pumping casing using the power delivery unit, the pumping efficiency is increased. |
