The invention discloses an electric breast pump, which relates to the field of maternal and child ware. The electric breast pump comprises a breast pumping cover I, a breast pumping cover II, a tee joint I, a tee joint II and a control main machine, and is characterized in that the main machine is internally provided with a vacuum pump I and a vacuum pump II, the vacuum pump I is connected with the tee joint I and the breast pumping cover I through a pipeline, the vacuum pump II is connected with the tee joint II and the breast pumping cover II through a pipeline, a control circuit of the control main machine is respectively used for controlling the vacuum suction force and the vacuum suction frequency of the vacuum pump I and the vacuum pump II, and a conversion gas valve can also be arranged between output pipelines of the vacuum pump I and the vacuum pump II. The electric breast pump is suitable for being used by puerperae who have two asymmetric breasts, such as the sizes and the milk yield of the breasts are different, and puerperae who have relatively good body health and sufficient milk, thus requiring larger vacuum suction force for accelerating the quantity of milk pumping so as to finish milk pumping in a short time. The electric breast pump has the characteristics of being convenient to use, being adapted to multiple requirements of different puerperae and the like.
