A ceiling fan assembly 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 canopy. The canopy can be received by a mounting bracket to enclose the mounting hardware near the ceiling.

A ceiling fan having a dual redundant motor mounting assembly for suspending a motor comprising a downrod, a hollow motor shaft suspending the motor from the downrod, a retaining pin extending through the hollow motor shaft, and a retaining rod coupled to the retainer pin for redundantly suspending the motor.

An ceiling fan comprising a motor system. The motor system is mounted around a motor shaft. The motor shaft couples to a downrod for suspending the ceiling fan from a structure. The motor shaft and motor are encased by a motor housing. The motor housing comprises hub arms for mounting a plurality of blade holders. The blade holders coupled to a plurality of blades rotatable about the motor during operation. The downrod comprises a wire disk mounting guy wiring to the downrod. A retention rod is utilized internal of the motor and downrod as a secondary retention method. An electrical connector is internal of the motor shaft and electrically couples to the stator to power the motor.

A blower device includes a pair of fans, a housing, and a lid. The pair of fans generates an airflow on one side in the axial direction along the central axis and is coaxially arranged. The housing has a tubular shape extending along the central axis, accommodates the pair of fans, and has two end surfaces opened in the axial direction. The lids cover axial end surfaces of the housing and provide ventilation. The lid includes an annular portion in contact with the inner peripheral surface of the housing and including a through hole penetrating in the radial direction. The housing includes an engagement protrusion that protrudes radially inward from the inner peripheral surface and engages with the periphery of the through hole.

A series fan frame body structure includes a first fan frame body, a second fan frame body and a serial connection frame body. The serial connection frame body has a first opening and a second opening. The first and second openings arranged in nonparallel to each other. The first and second fan frame bodies are respectively disposed at the first and second openings. The first and second fan frame bodies are inclined from each other. The first and second fan frame bodies are serially connected in a nonparallel form. Therefore, in the system, due to the resistance of the structure with such configuration, the audio frequency dipole structure is destructed so that the periodical noise and vibration characteristic are lowered.

The invention is about a foldable portable fan, which relates to the technical field of a fan, including an entity; the bottom of the entity is fixedly arranged with a connecting part, the connecting part is connected with a rotating part, one side of the rotating part is connected with a bolt, one end of the bolt is connected with a bolt column; the fan can conveniently connect the entity and the base together by setting a connecting part, a rotating part, a bolt and a bolt column, avoiding the use of screws, and the connection is very convenient; in addition, the entity can be folded between the base, which can save packaging materials, occupy less transportation space and save costs in logistics packaging; and the entity can be matched with different bases, thus providing higher selectivity and more flexible sale.

A motor including a support unit, a first rotating part, a second rotating part, a rotor and a stator is disclosed. The support unit includes an axle and a bearing coupled with the axle. The first rotating part is fit around the axle and is coupled with the bearing. The second rotating part is coupled with the first rotating part. The rotor is coupled with the second rotating part. The stator is connected to the support unit.

A magnetically attracted fan set comprises N+1 fans, the N≥1, and each of the N+1 fans has a fan frame and an airflow generating component disposed on the fan frame. Any two adjacent fans of the N+1 fans respectively have a joint surface, each of the joint surfaces has at least one fixing member capable of forming magnetic attraction, when the joint surface is close to the other joint surface at a distance sufficient for the two fixing members on the two joint surfaces to form magnetic attraction, two of the N+1 fans are joined together. Accordingly, the invention is capable of directly and quickly joining the N+1 fans without requiring complicated assembly gestures or other external components.

A hinge assembly includes a rotation shaft, a first connection member provided at the rotation shaft, a second connection member provided at the rotation shaft, located at one side of the first connection member along an axial direction of the rotation shaft, and configured to rotate around the rotation shaft, and an adjustment member connected to the rotation shaft and configured to press the second connection member along the axial direction of the rotation shaft.

A bottom-mounted whole house fan assembly includes an intake plenum mounted over an opening in a ceiling of a building. The intake plenum is supported on the ceiling in the attic of the building. One end of a flexible duct is connected to the intake plenum and the other end of the duct is connected to a fan so that the fan draws air in the building through the intake plenum and duct and exhausts the air in the attic from whence the air is vented to atmosphere. The fan is supported by at least one vertical strut that is connected to the ceiling at the lower end of the strut and to a housing of the fan at the upper end of the strut. A sound dampener is interposed between the strut and the fan housing and/or the ceiling beam to which the strut is attached.
