The invention relates to a wearable breast pump, and belongs to the technical field of mother and baby products. The breast pump is formed by connecting a main machine assembly and an integrated machine core assembly. Different from the prior art, an integrated functional assembly comprising a butterfly-shaped air bag, a one-way valve plate and a negative pressure channel groove is arranged, a negative pressure buffering air path is formed, negative pressure air flow in the breast suction cover flows horizontally, the extrusion pressure of negative pressure on breasts is relatively balanced, and the comfort of a breast-feeding person is improved when the breast-feeding device is used by the breast-feeding person. The negative pressure cavity is connected with the milk outlet through the long-strip flat negative pressure channel groove, the negative pressure acts on the breasts of the human body from the breast protection pad to the milk outlet, the thickness of the breast protection pad is gradually reduced from the two ends to the middle, and under the negative pressure effect, the thin area in the middle of the breast protection pad can deform more easily, so that the breast protection effect is better. And the human mammary areola part is squeezed and massaged to be consistent with the condition reflex arc of natural lactation of the human body, so that the electric milk suction can be closer to natural lactation.
