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 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 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.
