Abstract

There is provided a fan device using static fan blades and dynamic fan blades to change pressure, which includes a frame, a motor and at least a set of fan blades. The frame has a central through chamber with two end openings used as the inlet and the outlet respectively. The motor is arranged in the chamber, and the set of fan blades, which includes a static fan blade and a dynamic fan blade, is arranged in the chamber. The static fan blade is made in radial and helical protrusion while the dynamic fan blade is made in radial and reverse helical protrusion and also coaxially arranged along with the static fan blades set. Between the cross sections of each static fan blade corresponding to each dynamic fan blade, there is an included angle with which the draft pressure of the fan device is effectively increased.
