The invention discloses a new-type heat-dissipating blade uniform speed adjustment device of an electric fan, which comprises a rotating motor, a central shaft is arranged horizontally inside the rotating motor, and a blade disc is arranged vertically in the center of the rotating motor A connecting shaft is arranged around the inner center of the blade disk close to the central axis, and fixed leaves are arranged around the outer wall of the connecting shaft. The invention rotates the motor to drive the central shaft to rotate, the telescopic spring pulls the centrifugal block to move to the side of the connecting shaft, the connecting belt rotates to the orbiting shaft, and then drives the orbiting shaft to rotate so that the connecting belt is accommodated and driven by the connecting belt The power gear rotates, and then drives the connecting rod to rotate through the power gear. The connecting rod is clamped with the rotating wheel through the surrounding thread on the outer wall, which has the advantages of automatically adjusting the fan blade and automatically cleaning the dust attached to the surface of the fan blade.
Description
technical field [0001] The invention relates to the technical field of motor equipment, in particular to a device for adjusting the average speed of cooling fan blades of an electric fan. Background technique [0002] The motor will generate a lot of heat during the working process. If the heat dissipation is not carried out in time, it will affect the normal operation of the motor or even burn the motor. In order to improve the heat dissipation capacity, many heat dissipation structures are added to the motor. For example, the fan blade is a very important The heat dissipation structure is installed on the output shaft of the motor, and uses the rotation of the output shaft of the motor to drive the rotation of the fan blades of the motor to form an air path to achieve the purpose of cooling the components inside the motor. [0003] The rotation speed of the current motor can usually be adjusted, but when the motor speed changes, the rotation speed of the fan blade will als...
