The invention discloses an electrospinning apparatus comprising an AC high-voltage generator, a liquid supplying device including a micro-injection pump, an air supplying device, a spraying head including a liquid supplying channel connected with the liquid supplying device and an annular air supplying channel connected with the air supplying device, and a receiver including at least two rod-like supporting arms, a rotating shaft and a transmission device driving the rotating shaft to rotate. The air supplying channel sleeves the liquid supplying channel; an end part of an outlet section of the liquid supplying channel is provided with a tapered tipped end; the spraying head is connected with the AC high-voltage generator; one end of the supporting arm is fixedly connected with the rotating shaft and the other end is suspended in the air; the adjacent supporting arms are arranged at intervals; all the supporting arms form a bowl type revolving surface during the rotation of the rotating shaft; and the bowl typerevolving surface is opposite to a liquid outlet and an air outlet of the spraying head. Fibers with tiny diameters can be formed by the use of the electrospinning apparatus; the fiber filament diameters are evenly distributed and the fibers have fluffy structure and excellent mechanical properties; backswinging air flows can be avoided; and the electrospinning apparatus can be widely applied to organization engineering field.
