A ceiling fan assembly comprising a motor, a mount for coupling to a structure and for suspending the motor, and a ceiling fan blade comprising only a blade body for coupling to the motor, wherein the ceiling fan blade is formed from a molded pulp comprising at least one of paper fibers, plant fibers, or wood fibers.

A hidden fan and a fan lamp are disclosed. The hidden fan includes a turntable assembly and a plurality of fan blade assemblies arranged at the turntable assembly, the turntable assembly has a turntable and a limit wheel configured to rotate relative to the turntable, the turntable has a plurality of fan blade fixing portions, and the plurality of fan blade fixing portions are annularly arranged around a center of the turntable, at least one of the fan blade assemblies has a fan blade and a return elastic component, the fan blade has a fixed portion and a linkage portion arranged at a side of the fixed portion, the fixed portion is arranged at the corresponding fan blade fixing portion, the linkage portion is connected with the limit wheel.

A mounting base of a ceiling fan has a mounting disc, a fitting sleeve, and a positioning unit. The mounting disc has a through hole. The fitting sleeve is mounted in the through hole and has a hanging block located on an end of the fitting sleeve. The fitting sleeve is hung on the mounting disc via the hanging block. An accommodating space is formed through the fitting sleeve and is adapted to accommodate a hanging rod. The positioning unit is mounted in the accommodating space and is capable of engaging with the hanging rod. The positioning unit has a bending edge. The positioning unit is hung on the fitting sleeve via the bending edge. The mounting base has a simplified assembling process and a great stability in mounting structure.

A remote control system for forward/reverse rotation of a fan comprises a remote control and a forward-reverse rotation control unit. The remote control includes an operation module, a wireless output module, and a first control module that is electrically connected to the operation module and the wireless output module and that is capable of outputting, through the wireless output module, an operation signal which corresponds to an operation condition of the operation module. The operation signal can switch between a forward rotation mode and a reverse rotation mode to correspond to the operation condition of the operation module. The forward-reverse rotation control unit includes a wireless input module that is used to receive the operation signal, a double-pole relay that is controllable to switch between a first mode and a second mode and that is used to provide electric power to the fan, and a second control module that is electrically connected to the wireless input module and the double-pole relay and that controls the double-pole relay to switch modes according to the operation signal, thereby making a rotational direction of the fan correspond to the operation of the operation module and enhancing convenience of use.

A ceiling fan or blade thereof can include a fan motor for rotating the blade. The blade can include an airfoil body having an outer surface extending between a leading edge and a trailing edge, and a root and a tip. The blade can be separated into three distinct cross sections including a first cross section as a lifting cross section, a second cross section as a flat cross section, and a third cross section as a transition section between the first and second cross sections.

Various aspects of the present disclosure are directed to a fan quick release mechanism. In one example embodiment, the fan quick release may include: an upper coupling that attaches to a downrod hanging from a ceiling, a lower coupling that attaches to a fan/light/other electrical appliance, and a locking pin that couples the upper and lower couplings as desired. To further facilitate ease of assembly, electrical quick disconnects may be positioned within the respective upper and lower coupling assemblies—wherein coupling of the upper and lower couplings also results in the electrical quick disconnects electrically coupling as well.

A ceiling fan having double-layer blades includes a motor unit, a blade frame unit, a first blade unit, and a second blade unit. The blade frame unit has a blade frame body. The first blade unit includes a plurality of first blades. The second blade unit includes a plurality of second blades. The first blades and the second blades surround the outside of the blade frame body, so that there is no need for the motor unit to provide a motor housing for connecting the first blades and the second blades, thereby saving costs and installation costs. With the arrangement of the first blades and the second blades, the ceiling fan can increase the current of air for cooling.

A ceiling fan including a retention system and method of redundantly retaining a ceiling fan can include a ceiling fan motor assembly including a hollow motor shaft at least partially surrounded by a motor housing. A retainer plate is provided at the bottom of the motor housing including an opening. A retainer rod extends through the opening in the retainer plate and secures to the retainer plate. A support cable couples to the retainer rod to suspend the retainer plate from a structure, wherein the retainer plate is configured to redundantly retainer the ceiling fan.

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a ceiling fan mount with a dual axis gimble. The dual axis gimble can be received by a mounting bracket so that at least a first and second axis of rotation are provided to the ceiling fan assembly.

A wall fan suspension structure comprises a wall-side coupling element with a first bottom plate part and a first side plate part connected to each other, the first bottom plate part extends from the first side plate part, and the first bottom plate part is provided for locking on a wall surface; and a fan-side coupling element with a second bottom plate part and a second side plate part connected to each other, the second bottom plate part extends from the second side plate part, the second bottom plate part is provided for coupling with a wall fan, and the second side plate part and the first side plate part are connected by sleeving with each other.
