Electric fan, electric fan swing control device and swing control method

The invention discloses an electric fan, an electric fan swing control device and a swing control method. The electric fan swing control device comprises a first motor, a second motor and a controller, wherein the first motor is used for controlling the horizontal swing of the electric fan; the second motor is used for controlling the vertical swing of the electric fan; a first end and a second end of the controller are respectively connected with the first motor and the second motor, a first control signal is output by the first end, a second control signal is output by the second end, and the conducting time of the first control signal is different from that of the second control signal. Therefore, the electric fan is driven to vertically swing and horizontally swing for different time through the outputting of the first control signal and the second control signal with different conducting time, the swing moving trajectory of the electric fan continuously varies, large-range air blowing is realized, the air blowing region does not have a dead zone, and the user experience is improved.
