A direct-current (DC) electric fan configured for cooling purposes and for use in all places includes a base, a plurality of fixed-height interconnected inner and outer tubes extending upward from the base, and a driving motor provided in the base for driving the inner and outer tubes into reciprocal rotation, thereby simultaneously driving the fan unit mounted to each inner tube and between each two adjacent outer tubes to rotate over a predetermined rotation range. The blowing direction of each fan unit is also manually adjustable so that the blowing range of the fan can be adjusted and set according to personal needs.
