摘要： A ceiling fan includes an adapting assembly having at least one rotary shaft and a lower sealing ring. Each rotary shaft has a seat being semi-circular and a guiding portion being semi-spherical and having a guiding surface. The lower sealing ring has at least one protrusion. The guiding portion is mounted through the lower sealing ring and the guiding surface abuts against the at least one protrusion. With the seat of the rotary shaft being semi-circular and the guiding portion being semi-spherical, when the rotary shaft is rotated, the guiding surface and the at least one protrusion coordinate with each other to rotate. The adapting assembly has reduced volume. Accordingly, the ceiling fan is lightweight, has reduced power consumption and manufacturing cost, and is easy for installation.

摘要： Apparatus and methods for circulating air. The apparatus may include a ceiling fan and may include a light fixture. A motor assembly may drive the fan about a rotational axis. Blades of the fan may be fixed to an outer ring of a blade bracket. Blades may extend away from the outer ring. The blade bracket may also include a translucent blade support to which the outer ring may be fixed. The translucent blade support may be disc shaped. A blade holder adapter may fix an inner portion of the translucent blade support to the ceiling fan. The fan may be configured such that a portion of the translucent blade support may provide a view unobscured by the translucent blade support so that there may be at least partial visibility of a visible element, such as a structure, above the translucent blade support from below the apparatus.

摘要： A misting fan includes a nozzle, a fan assembly, and a support assembly. The nozzle is configured to spray water. The support assembly is formed with a coupling portion for detachably coupling a battery pack. The nozzle is disposed on the fan assembly or the support assembly and includes a nozzle body and a second part. The nozzle body includes a first part formed with a first surface and the second part is detachably installed to the nozzle body and formed with a second surface. When the second part is installed to the nozzle body, a water flow channel is formed between the second surface and the first surface. When the second part is detached from the nozzle body, the first surface is at least partially exposed for cleaning access.

摘要： A ceiling fan or ceiling fan includes a body defining an interior passage having an inlet and an outlet provided on the body. The inlet, outlet, and interior passage can be annular. An impeller is mounted within the interior passage and driven by a motor mounted within the body to draw a volume of air through the interior passage from the inlet to the outlet. A movable deflector including an inner angled surface and a lower angled surface is provided at the outlet to direct the airflow in a generally outward or generally downward direction, respectively.

摘要： A fan brake system for controlling an industrial fan system, the fan brake system including a fan brake having a brake pad movable on the fan brake to selectively engage the fan system. An actuator including a motor can be operable to cause the fan brake to perform a braking procedure on the fan system to resist rotational movement of the fan system. A controller can be communicated with the actuator, the controller operable to selectively cause the actuator and the fan brake to perform the braking procedure, wherein the controller is operable to monitor and control power being supplied to the motor of the actuator during the braking procedure to maintain a torque output of the motor according to a predetermined torque profile during the braking procedure.

摘要： A blower includes a body, a motor, and a single fan configured to rotate in response to rotation of a motor shaft to discharge air through a discharge opening. The maximum rotational speed of the motor shaft is within a range of 50,000 rpm to 120,000 rpm. An area of the discharge opening is changeable by a user. The blower is configured to selectively operate in a first mode or in a second mode according to the area of the discharge opening. In the first mode, the maximum blowing force of the air discharged through the opening is within a range of 2.5 N to 5.0 N when the motor is driven at the maximum rotational speed. In the second mode, the maximum dynamic pressure of the air discharged is within a range of 30 kPa to 65 kPa when the motor is driven at the maximum rotational speed.

摘要： A battery powered fan assembly for use with a stackable storage system includes a base defining a storage area, a fan housing that at least partially defines an airflow chamber, a plurality of fan blades positioned within the airflow chamber, a motor operable to rotate the plurality of fan blades, a battery receptacle configured to receive a removable battery pack to power the motor, a mating interface formed on at least one of the base and the fan housing, and a latch mounted to the base. The mating interface is configured to interact with a complementary mating interface formed on a stackable element of the stackable storage system, and the latch is configured to selectively inhibit relative movement between the fan assembly and the stackable element while the mating interface of the fan assembly interacts with the complementary mating interface of the stackable element.
