Abstract: A transmission device of a fan is provided. A central axis and an eccentric position of the transmission device are connected with a spindle and a connecting rod, respectively. The spindle is connected with a motor through gears. A first casing and a second casing of the transmission device are pivotally connected to each other. An accommodation hole of the second casing is provided with an elastic member and a press member to engage with an engaging recess of the first casing, such that the fan can be swung. When the user applies a force to change the angle of the fan, the press member is pressed by two press portions of the first casing to disengage from the engaging recess, such that the second casing can be turned relative to the first casing to prevent gear slipping or gear jumping of the motor, the gears, and the spindle.

Abstract: A ceiling fan with gesture induction function includes a switch box provided beneath a motor housing and a blade unit. The switch box is installed therein with a transmitter, a receiver and a controller. The controller can drive the transmitter to transmit a wireless signal to the receiver and further control at least one electrical apparatus of the ceiling fan through reception of a sampling signal of the receiver. The ceiling fan with gesture induction function of this invention enables a user to control the electrical apparatus of the ceiling fan by employing gesture to obstruct the wireless signal, and is unnecessary to disassemble the motor housing and the blade unit for repair of the facilities in the switch box so the ceiling fan with gesture induction function of this invention is safer and more convenient in maintenance.

Abstract: A waterproof structure of a wall-mounted fan housing includes a housing. One side of the main housing is fitted on the outer wall of a first secondary opening of the secondary housing. The housing and the accommodation space of the housing are inclined downward from the main housing toward the secondary housing, preventing rainwater from entering the housing. Another side of the secondary housing has a second secondary opening. The housing is provided with a first drain hole and a motor therein. The first drain hole is disposed at the bottom of the housing close to the second secondary opening of the secondary housing so that rainwater can be discharged from the first drain hole.

Abstract: A detachable blade structure has a blade seat, a motor, a cover plate, a spherical cover, a blade, a detachable member and first and second screws. The spherical cover has a cover slot, a cover positioning hole and a cover screw hole. The cover plate has a chamber. The blade is inserted through the cover slot and inserted into the chamber. The blade seat has a first seat lug, a first seat screw hole, a second seat lug and a second seat screw hole. The motor has a motor positioning hole and a motor screw hole. The first seat lug is inserted into the motor positioning hole. The first screw is screwed into the first seat screw hole and the motor screw hole. The second seat lug is inserted into the cover positioning hole. The second screw is screwed into the second seat screw hole and the cover screw hole.

Abstract: A fan capable of generating omnidirectional airflow includes a central shaft and a fan body. A windward surface of each of blades of the fan body and a radial direction of a motor of the fan body are perpendicular to each other. The central shaft is perpendicular to an axial direction of the motor. The fan body is connected with one side of a support unit. The central shaft is connected with a rotary device. The central shaft is fixed to the support unit. The rotary device can drive the support unit to rotate relative to the central shaft. When the fan is actuated, the blades generate 360-degree outward airflow, and the support unit is rotated by the rotary device so that the fan can generate omnidirectional airflow.
