The present invention provides an electric breast pump. The electric breast pump includes a conduit module, a suction module and a host. The conduit module includes a connector, a first conduit and a second conduit. The connector has an electric contact and an opening hole, and the connector is further disposed with a protrusion at the side of the connector on which the opening hole is formed. The first end of the first conduit connects to the electric contact. The first end of the second conduit connects to the opening hole. The suction module has an adapter body coupled with the connector to connect the suction module and the conduit module. The host connects to the second end of the first conduit and the second end of the second conduit. The host controls the suction module via the conduit module to extract and collect milk when the suction module contacts mothers breast.一種電動吸乳器,包括導管模組、吸乳模組以及主機,該導管模組包括接頭、第一導管及第二導管,該接頭具有電性接點及開孔,該接頭形成有該開孔之一側復設有凸部,該第一導管之其中一端連接於該電性接點,該第二導管之其中一端連接於該開孔,該吸乳模組具有轉接座本體,該轉接座本體藉由與該接頭相結合以連接該吸乳模組與該導管模組,該主機與該第一導管及第二導管用以連接於該接頭之一端的相對端相連接,其中,該主機係透過該導管模組控制該吸乳模組,以於該吸乳模組接觸乳房時汲取並收集乳汁。1‧‧‧導管模組11‧‧‧接頭12‧‧‧第一導管13‧‧‧第二導管
