The support ring is located in the circular groove, and a plurality of conjugation protrusions are provided on the support ring, the plurality of conjugation protrusions are uniformly distributed on the peripheral surface of the support ring; and the conjugation protrusions and the conjugation pores are plugged with each other one by one and can ensure that the mating base 24 and the support ring are integrated together.

As shown in FIG. 5 and FIG. 6, in one embodiment of the present disclosure, the support ring is made of rubber, the hardness of the support ring is larger than that of other rubber parts on the breast suction shield 5. The port ring includes a pluggable ring 14 and an epitaxial ring 12 that are integrated together. Wherein, the epitaxial ring 12 is between the pluggable ring 14 and the absorption portion 7, and can play a role of supporting the absorption portion 7, thus ensure the reliability of fitness of the absorption portion 7. In particular, the epitaxial ring 12 is arranged coaxially with the absorption portion 7, and the profile of the epitaxial ring 12 is small than that of the absorption portion 7, which can make the hardness of the central part of the absorption portion 7 is large and not easy to deform, while the hardness of the edge parts is small and easy to fit.

Further, in the present embodiment, the pluggable ring 14 May have various shapes, for example, the pluggable ring may take an ellipse or a circle shape etc. When the pluggable ring 14 is ellipse-shaped, and the major axis of the ellipse is arranged vertically, and the minor axis of the ellipse is arranged horizontally, it can ensure the correctness of connection between the breast suction shield 5 and the breast pump principal machine 2 and play an error-proof role. Both ends along the direction of the minor axis each is provided with one positioning groove 13, this can ensure the connecting reliability between the breast suction shield 5 and the breast pump container. When the pluggable ring 14 is circle-shaped, two positioning grooves 13 are on both ends of the same diameter of the circle, the pluggable ring 14 is more prone to be modeled, convenient to be manufactured, and easy to save cost when taking a circle shape.

When the solenoid valve is off, the sealing chamber 29 has a negative pressure with the action of the air pump 10, the suction portion expands, and the emulating contact ring 8 extrudes the mammary areola and then sucks milk; when the solenoid valve is on, the inside of the sealing chamber 29 recovers to the atmosphere pressure, the suction portion contracts, and the emulating contact ring 8 expands. The solenoid valve is on and off uninterruptedly, which can emulate a scene that a baby is sucking the milk, and then the sucked milk enters into the milk bottle 1 from the milk leakage hole 21 through the connecting cover and the one-way valve 18. The one-way valve 18 acts to conduct in one-way manner, can allow the milk and gases to go through, rather than allowing the milk and gases to flow back, and can cooperate with the solenoid valve to form a sealing environment together.

As known by common technical knowledge, the present can be implemented through other schemes that are not departed from the spiritual essence or necessary features. Therefore, in terms of various prospects, the above-mentioned schemes are only exemplary descriptions, not limitation thereof. All changes fall within or equivalent to the scope of the present disclosure are included into the present disclosure.
