Abstract: A double-layer blade ceiling fan capable of adjusting the arrangement of blades includes a motor and at least two blades. The motor has a stationary part and two rotating parts. The rotating parts are spaced apart from the stationary part. The rotating parts each have a plurality of mounting portions that are arranged around a central axis of the motor. The stationary part has an upper connecting portion and a lower connecting portion. The mounting portion is configured for connection of one of the blades. At least one of the blades is fixed to each of the rotating parts. The blades mounted to the rotating parts are selectively arranged in a same or different pattern for regulating air flow. When the blades and the rotating parts are rotated, the upper connecting portion and the lower connecting portion are not affected.

Abstract: A motor and blade mounting structure of a ceiling fan, the ceiling fan has a motor, at least one bracket, and at least one blade. The at least one bracket has at least one mounting portion. The mounting portion of the at least one bracket is configured for mounting the at least one blade. The motor has a rotor. The rotor of the motor is fixedly connected to the at least one bracket. The motor and blade mounting structure enhances assembly convenience, safety, structural support and durability.

Abstract: A fan blade installation structure of a ceiling fan, the ceiling fan has at least one fan blade, at least one socket, and at least one elastic member. The elastic member is fixed to a periphery of the socket. The elastic member has an open end provided with a holding portion corresponding to a blade hole of the fan blade. The holding portion is elastically moved in and out of the socket. The holding portion has a guide surface for guiding the fan blade. The open end of the elastic member further has an operating portion outside the socket for a user to move the elastic member. The fan blade installation structure has the effects of installing and removing the fan blade quickly, easy assembly, and good assembly safety.

Abstract: A ceiling fan infrared detection and control system has a wall-mounted controller, a ceiling fan controller, and a motor. The wall-mounted controller has an infrared sensor that is arranged outwardly and horizontally. The wall-mounted controller is pivotally equipped with a lens outside the infrared sensor for detecting infrared rays of a human body within a detection range. The control unit can output a wireless signal to the ceiling fan controller to control the motor according to the infrared detection result. The ceiling fan infrared detection and control system uses the technical feature that the lens is rotatable relative to the wall-mounted controller, so that the detection range can be moved synchronously along with the lens. The detection range has directivity and the function of adjusting the detection position, which can avoid false detection of a pet below the height of the detection range.

Abstract: An outdoor ceiling fan includes a ceiling fan body, a lower tube fixedly connected to the ceiling fan body, and an upper tube insertedly connected to the lower tube. The upper tube is telescopic and adjustable relative to the lower tube through an adjustment seat. A hanger is fixedly connected to the upper tube. The hanger covers the top of the upper tube. A waterproof gasket is provided between the housing of the ceiling fan body and the lower tube. A waterproof ferrule is provided among the upper tube, the adjustment seat and the lower tube. The outdoor ceiling fan has the effects of blowing air over a large area, being waterproof, and having a retractable down rod, lighting function and good safety.

Abstract: A quick assembling structure includes a first seat, a second seat, and two elastic plates. The first seat and the second seat are configured to be coupled to a ceiling fan body and a lamp. The first seat has two bars. The second seat has two bar entrances, two longitudinal grooves, and two guide grooves. The elastic plates are disposed in the respective guide grooves, and each have a contact portion and a holding portion. When in use, the bars of the first seat are inserted into the bar entrances, the longitudinal grooves and the guide grooves, the bars are pushed to pass through the contact portions of the elastic plates, and the bars are secured between the contact portions and the holding portions of the elastic plates and the guide grooves.
