Ceiling fan adaptable to cyclic motion
A ceiling fan adaptable to cyclic motion includes a power unit pivotally connected with a support unit via a transmission unit. The power unit is fixedly provided with a ceiling fan housing, which has a topside and a bottom side respectively provided with an opening and a through hole, the through hole corresponding to a rotating shaft of the power unit. When the ceiling fan is operated, the power unit will pivotally turn along the support unit and drive the blade unit to rotate and actuate the air around to blow toward the front of the blade unit along the periphery of the ceiling fan housing. By so designing, the interior of the ceiling fan is not easy to accumulate batting and dust, and heat of the power unit can be exhausted through the opening at the topside of the ceiling fan housing.
1. A ceiling fan adaptable to cyclic motion comprising:
a support unit having a supporting rod at an upper side;
a transmission unit;
a power unit pivotally connected with the supporting rod of said support unit via said transmission unit, said power unit provided with a first motor, said first motor formed with a rotating shaft;
a blade unit fixedly connected with the rotating shaft of said first motor; and
a ceiling fan housing secured with said power unit, said ceiling fan housing provided therein with an accommodating space, said accommodating space of said ceiling fan housing receiving said power unit, said ceiling fan housing having a top side provided with an opening, the supporting rod of said support unit passing through said opening, said ceiling fan housing having a bottom side bored with a through hole corresponding to the rotating shaft of said first motor,
wherein the rotating shaft of said first motor slants in relation to the supporting rod of the support unit and the opening of said ceiling fan housing is made sufficiently wide, such that when said power unit turns pivotally around the support unit, the ceiling fan housing as a whole turns together with said power unit in a slanted cyclic motion without interference from said support unit, while allowing air in the accommodating space of the ceiling fan housing to freely flow out through the opening for heat dissipation.
2. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said power unit is further fixed with a second motor, said second motor formed with a rotating shaft, said power unit pivotally connected with said support unit via both the rotating shaft of said second motor and said transmission unit.
3. The ceiling fan adaptable to cyclic motion as claimed in claim 2 , wherein a wireless receiving controller is further provided, said first motor and said second motor electrically connected with said wireless receiving controller.
4. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said ceiling fan housing comprises an upper housing and a lower housing combined together, said lower housing secured with said power unit, said lower housing mounted at a location adjacent to the rotating shaft of said first motor, said lower housing bored with said through hole corresponding to the rotating shaft of said first motor, said upper housing fixed on said lower housing, said upper housing provided with said opening.
5. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said support unit is formed with two downward-extending arms at a lower side, adjacent to said power unit, and said power unit is positioned between said two downward-extending arms.
6. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said support unit is formed integrally or composed of several components or made of different components.
7. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said transmission unit is composed of bearings and connecting rods.
8. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said blade unit is formed with a screening portion at a location adjacent to the rotating shaft of said first motor, said through hole being smaller than said screening portion, said screening portion having a continuous surface for covering and blocking view of said through hole.
9. The ceiling fan adaptable to cyclic motion as claimed in claim 1 , wherein said ceiling fan housing is constructed such that air is able to move in and out only through said opening.
