| 摘要 |
<p>The invention relates to a fan comprising a kinematic system which is disposed inside a frame that is affixed to a ceiling. Said kinematic system conveys a to-and-fro oscillating movement to an axle, from which the fan is suspended, by means of a connecting rod/crank system which is equipped with a motor comprising a revolution reduction mechanism and an electronic speed variation circuit. Said system transmits the oscillating movement to a transversely-fixed axle which is secured using bars, said bars being articulated by means of a knuckle joint. In this way, the to-and-fro movement is transmitted to the fan which is fixed to the axle bar by means of a sail-type pressure system or by means of pressure from another parallel bar which is connected to the aforementioned axle bar by means of screws. The base of the fan comprises another bar which acts as a ballast and which supports essence holders at the ends thereof.</p> |
