Abstract

A twin headed fan with 360 degree oscillation has a fan's base (30) connected to a first rotating shaft (31) by a first gear (41). This allows the first rotating shaft (31) to rotate the fan's base (30) 360 degree. A connecting point between the first rotating shaft (31) and the fan's base (30) acts as a first pivot point (61). A connecting point between a first fan (51) and the fan's base (30) acts as a second pivot point (62) which enables vertical movement of fan's blades on the first fan (51). A connecting point between a second fan (52) and the fan's base (30) acts as a third pivot point (63) which enables vertical movement of fan's blades on the second fan (52). A first motor (11), a second motor (12) and a third motor (13) operate simultaneously to enable 360 degree horizontal oscillation and fan's blades vertical adjustment functions of the twin headed fan.
