- The present invention relates to a rotation control device of a multi-rotor ceiling fan.
- 2. Description of the Prior Art
-
FIG. 1 is a side view of a conventional multi-rotor ceiling fan. The conventional multi-rotor ceiling fan comprises ashaft 1. One end of theshaft 1 is pivotally connected with aseat member 2. The other end of theshaft 1 is fixed to the ceiling (not shown in the drawing). Theshaft 1 is provided with a power supply portion 3 which is located close to theseat member 2. Theseat member 2 is provided with acorresponding load portion 4. Theload portion 4 gets contact with the power supply portion 3. Theseat member 2 is provided with a pair ofsupport rods 5 extending outward. The distal ends of thesupport rods 5 are respectively connected with afan 6. Thefans 6 are electrically connected to theload portion 4. When the multi-rotor ceiling fan is started, the power supply portion 3 will supply power to theload portion 4. Theload portion 4 further transmits the power supply to thefans 6, such that thefans 6 are rotated. By the inertia force generated by rotation of thefans 6, thefans 6 also revolve round theseat member 2, producing airflow to the surrounding by 360-degree rotation. - However, because the
fans 6 revolve round theseat member 2 by the inertia force generated by rotation of the fans, the revolution speed of thefans 6 will be influenced by the rotation speed of thefans 6. That is to say, the higher the rotation speed, the higher revolution speed there will be. That results in that the conventional multi-rotor ceiling fan cannot produce stable airflow to the surrounding by 360-degree rotation. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems. - The primary object of the present invention is to provide a rotation control device of a multi-rotor ceiling fan to produce stable airflow to the surrounding by 360-degree rotation.
- In order to achieve the aforesaid object, the rotation control device of a multi-rotor ceiling fan of the present invention comprises a fixed unit, a fixed gear, a movable unit, and a driving member. The fixed unit has a housing. The housing has an accommodation room and an opening at one side thereof. The housing further has an axial hole at another side thereof. The fixed unit comprises a shaft connected to the axial hole. The shaft is provided with a power supply portion. The fixed gear is fixed to the fixed unit. The fixed gear has a fixed toothed portion which is disposed round the shaft. The movable unit comprises a seat member which is pivotally connected to the shaft. The movable unit comprises at least one pair of support rods extending outward from the seat member and disposed relative to the shaft. The distal ends of the support rods are respectively connected with a fan. The seat member of the movable unit is provided with a load portion. The load portion gets contact with the power supply portion. The driving member is fixed to the movable unit and has a motor. The motor is electrically connected to the load portion. The motor is further connected with a driving gear. The driving gear has a driving toothed portion. The driving toothed portion meshes with the fixed toothed portion.
- The driving member is fixed to the seat member, the seat member is pivotally connected to the shaft, and the fixed gear is fixed to the shaft and not free. When the multi-rotor ceiling fan is started, the driving gear is moved along the inner edge of the fixed gear and synchronously brings the seat member to rotate with the shaft as the center shaft. Thus, the movable unit turns at a constant speed relative to the fixed unit for the fans connected to the support rods to revolve round the fixed unit, producing stable airflow to the surrounding by 360-degree rotation.

When the multi-rotor ceiling fan is started, thepower supply portion 13 will supply power to theload portion 33. Theload portion 33 further transmits the power supply to themotor 41, such that themotor 41 runs to drive the drivinggear 42 to turn. Because the drivingmember 40 is fixed to theseat member 31 and theseat member 31 is pivotally connected to theshaft 12 and the fixedgear 20 is fixed to theshaft 12 and not free, thedriving gear 42 is moved along the inner edge of the fixedgear 20 as shown inFIG. 4 and synchronously brings theseat member 31 to rotate with theshaft 12 as the center shaft. Thus, themovable unit 30 turns at a constant speed relative to the fixedunit 10 for the fans connected to thesupport rods 32 to revolve round the fixedunit 10, producing stable airflow to the surrounding by 360-degree rotation. - It is noted that the fixed
toothed portion 22 of the fixedgear 20 meshes with the drivingtoothed portion 421 of thedriving gear 42 to resist the inertia force generated by rotation of the fans. Therefore, themovable unit 30 can be turned steady relative to the fixedunit 10 by the drivingmember 40, not influenced by the rotation speed of the fans. -

The fixedgear 20 is adisc member 23. Thedisc member 23 has a throughhole 231 at a central portion thereof for connection of theshaft 12. Thedisc member 23 is fixed to theshaft 12 and located between thelower seat 311 and theupper seat 312. Thedisc member 23 has the fixedtoothed portion 22 around an outer wall thereof. The fixedtoothed portion 22 meshes with the drivingportion 421 of the drivingmember 40. The fixedgear 20 is fixed to theshaft 12 and not free. When the multi-rotor ceiling fan is started, thedriving gear 42 is moved along the inner edge of the fixedgear 20 as shown inFIG. 7 and synchronously brings theseat member 31 to rotate with theshaft 12 as the center shaft. Thus, themovable unit 30 turns at a constant speed relative to the fixedunit 10 for the fans connected to thesupport rods 32 to revolve round the fixedunit 10, producing stable airflow to the surrounding by 360-degree rotation. The second embodiment achieves the same effect as the first embodiment. - Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention.
