Abstract

The invention discloses an electric fan with the head shaking angle adjustable. The electric fan comprises fan blades, a motor, a control circuit board, a supporting column and a base, wherein an output shaft of the motor is coaxially connected with the fan blades; the base for containing the control circuit board is arranged below the motor; the motor is contained in a shell, and the shell is connected with the upper end of the supporting column through a rotating mechanism; the rotating mechanism comprises a supporting motor and a steering shaft of the fan blades, and the steering shaft is coaxially connected with a steering motor arranged in the supporting column. According to the technical scheme, the designed electric fan has the function that the head shaking angle of the electric fan can be freely adjusted, when the electric fan is used, the head shaking angle of the electric fan can be adjusted according to the number of people sitting in front of the fan, and idle work of the electric fan is avoided.

Description

technical field [0001] The invention relates to an electric fan, in particular to an electric fan which can adjust the swinging angle. Background technique [0002] An electric fan is a common household appliance. It drives the fan blades through a motor to increase the speed of air flow and accelerate the evaporation of sweat on the surface of the human body, thereby bringing bursts of coolness. In order to allow several people in the room to enjoy the wind, a fan that can shake their heads is designed. [0003] The control device of the widely used electric fan shakes the head at present is to drive the connecting rod by the motor main shaft worm and the worm gear of the electric fan blade, so that the electric fan swings back and forth according to a certain angle. The head shaking angle of this kind of mechanical electric fan is fixed, and sometimes the range of air supply is limited, and sometimes when the head shaking angle is smaller, it cannot meet the demand. Ther...
