Centrifugal fan with 360 degree continuous rotation
Abstract:
This patent discloses a fan capable of 360 degree continuous rotation. The fan may include an impeller positioned within the impeller housing, an impeller motor fixed to the impeller housing, where a control knob may control the impeller motor. The fan further may include an impeller shaft connected between the impeller and the impeller motor to rotate the impeller and the impeller housing may reside on a base. A contact ring may be positioned within the base. The impeller motor and the impeller housing may rotate relative to the contact ring, which may provide power to the impeller motor through brushes. A housing motor may be positioned within the base and be connected to the impeller motor to rotate the impeller motor. A housing motor switch may control the housing motor.
