  • Patent number: 7652439
    Abstract: A change-over device of pull cord control and wireless remote control for a DC brushless-motor ceiling fan is to have a driver installed in a ceiling fan basic body, and the driver has a detecting unit for detecting whether or not a connector positioned in a hanging bell is connected with a wireless control switch unit so as to control the blades of the DC brushless-motor ceiling fan to rotate by pull cord control or by wireless remote control. Further, the connector is installed inside the hanging bell; therefore, when the DC brushless-motor ceiling fan is to be additionally provided with a wireless control switch unit, it is convenient and safe in installation.

  • Patent number: 7621498
    Abstract: A hanger for a ceiling fan is formed with a conical receiving opening contracted downward gradually and having a hard hanging spherical member received therein. The hanging spherical member has its outer circumference annularly provided with a stop ring whose diameter is larger than the inner diameter of the receiving opening. A shock-absorbing cover is covered around the outer circumference under the stop ring of the hanging spherical member, having its inner circumferential camber matching with the outer circumferential camber of the hanging spherical member to enable the shock-absorbing cover to stably cover the hanging spherical member, and its outer circumference completely touching the inner edge of the receiving opening, avoiding the hanging spherical member dropping downward, preventing noises from produced and effectively elevating stability of the hanger.
