Abstract:
A main unit of an electric breast pump, comprising a power supply, and a main unit casing (2), a pump casing (1) and a pump body (4) sequentially disposed from outside to inside; a pump upper casing (1a) and a pump lower casing (1b) joined to form the pump casing (1) and tightly fit together forming an enclosed inner cavity; and an air hole (1c) is also provided on the pump casing (1). The present invention maximizes the enclosure of the working space of a pump body, and improves a battery compartment (8) to maximize the sealing property, thus effectively blocking the outward transfer path of the working noise of the pump body, effectively reducing the working noise of the main unit of the electric breast pump.
