Abstract
A device for expressing milk, with a vacuum-generating unit, which includes a drive motor and a vacuum-generating device, with a switching unit, which is linked to the vacuum-generating unit and determines the suction cycles via a rotatably driven switching member, and with at least one milk expression attachment, which is or can be brought into flow communication therewith and which includes a suction funnel that can be placed on the breast, and a milk collection receptacle. A compact design with reliable function is achieved by the switching member being coupled to the drive motor of the vacuum-generating unit via a transmission for the rotary drive.
Claims20
A milk-extraction device with a drive motor (1.1) and a vacuum generation unit (1) having a vacuum-generating device (1.2, 1.2′), a change-over unit (2) attached thereto which determines extraction cycles by a rotatingly driven change-over member (2.10), and at least one extraction attachment (10, 10′) which can be brought into a flow connection with it and having a suction funnel (6) which can be applied to a breast, and a milk receptacle (7), the milk-extraction device comprising:
- for being rotatorily driven, the change-over member (2.10) coupled via a gear train (20) with the drive motor (1.1) of the vacuum generation unit (1).
