The invention discloses a sphere electric iron, comprising not only an iron body, a bottom plate, a handle, a electric heating component, a temperature sensor, a control unit, but also rolling spheres, wherein, the rolling sphere is arranged on the bottom plate through bearings on the both sides and is protruding from the lower part of the bottom plate, so when ironed, the clothing are contacted through rolling friction contact clothing but sliding friction; the electric heating component is arranged in the ball, the positive and the negative power cords is led out separately by the bearings on the both sides of the rolling sphere after electric brushes; the temperature sensor locates above the rolling sphere, below the iron body. The structure of the invention is simple, the rolling sphere irons folds through stress concentration, the ironing efficiency for folds is improved, and the invention is suitable for all electric irons.
