The invention provides a dual-winding type ion air supplying module. The dual-winding type ion air supplying module comprises a plurality of discharging needles and a metal net; the metal net comprises a framework, a tension spring and two metal lines; one ends of the two metal lines are fixed on the framework separately; the other ends of the two metal lines are connected together through the tension spring; the two metal lines are mutually crossed and wound on the framework; the two metal lines form multiple crossed nodes in a region formed by the framework in a surrounding manner; and the needle point of each discharging needle and the corresponding crossed node are oppositely arranged. The air supplying speed, air supplying quantity and air supplying efficiency of the dual-winding typeion air supplying module are improved.
