[0033] Specifically, the milk receiving bowl 1 and the main machine 6 are combined to form a regular shape of an integrated structure, specifically, a hemispherical or semi-hemispherical or an integrated structure with a curved surface which is matched with the shape of the human chest.

[0034] Further, the check valve is a flexible opening and closing sheet 7 arranged at the third port 5.3, the opening and closing sheet 7 is at least partially fixed at the third port 5.3, and in a normal state, the third port 5.3 is in a closed state, and under the action of external force, the third port 5.3 is opened. When milk flows through, the opening and closing sheet 7 is pushed away to make the milk flow out, and then due to the flexible material of the opening and closing sheet 7, it automatically resets to close the third port 5.3.

[0035] Further, specifically, the elastic diaphragm 4 can closely cover the second port 5.2, thereby ensuring the sealing property of the second port 5.2. The second port 5.2 is provided with a cover body 5.2.1 extending and diffusing towards the elastic diaphragm 4 in the circumferential direction, the cover body 5.2.1 is matched with the shape of the elastic diaphragm 4 and covers the elastic diaphragm 4, and the outer edge of the elastic diaphragm 4 is provided with an abutting portion 4.1 protruding outward and abutting against the cover body 5.2.1 in the circumferential direction.

Under the action of the air pump, the elastic diaphragm 4 elastically deforms towards the direction opposite to the protruding direction, thereby generating a negative pressure at the second port 5.2 which is in close cooperation with the elastic diaphragm 4, and the negative pressure is transmitted to the chest through the flow-through part 3 and the trumpet cover 2 and the breast milk is sucked out. The breast milk after being sucked out flows to the third port 5.3 through the flow-through part 3, and then flows into the breast cup 1, and the check valve of the third port 5.3 can effectively prevent the backflow of the breast milk. The integration of the elastic diaphragm 4 and the breast cup 1 can effectively prevent the breast milk from being sucked into the main machine 6 through the gap.
