Abstract

The present invention discloses a breast pumping system comprising a housing, an air pump, a milk container, a pipe, a diaphragm, a shield and a cover, wherein, when the air pump acts on the air chamber through the vent pipe, the diaphragm is distorted so as to form a negative pressure inside the receiving chamber of the pipe, accordingly the milk from the passage flows into the storing chamber of the milk container after passing through the receiving chamber and the lower port successively. The air chamber can be manufactured larger in size so as to improve the pumping effect of the breast pump. When the air pump is an air pump with large pumping force, the pumping power can be further increased, and the pumping effect of the breast pump can be improved. The diaphragm is directly sealed to the cover, so that the sealing effect is good, it is not easy to cause air leakage, and the structure is reasonable and reliable.
