Fig. 1 schematically shows a structural diagram of a breast pump provided in the technical solution of the present disclosure. As can be seen from fig. 1, the breast pump 10 includes a suction cup 101, a suction port 102 located at the center of the suction cup 101, and a pressure opening 103 provided at the suction port 102. The pressure opening 103 is a part connected to the flow guide channel and can be opened by negative pressure to facilitate the sucking of milk and to allow the milk to flow through the flow guide channel to the milk storage device. It should be noted that: the pressure opening 103 is an opening that can be opened when receiving a pressure in a predetermined direction, and in the present embodiment, the pressure in the predetermined direction is the above-mentioned negative pressure, that is, the pressure directed from the opening of the suction cap 101 to the suction port 102.

Illustratively, the suction cup 101 has a trumpet-shaped opening for attaching to a surface of a breast so that the breast is received in the suction cup 101. The suction opening 102 is located at the tip of the trumpet-shaped opening, i.e., the tightening end, and the nipple can be just corresponding to the position of the suction opening 102 when the breast is received in the suction cup 101. Since the suction port 102 has a certain length, the pressure opening 103 is provided at a certain distance from the tightening end of the trumpet-shaped opening, and the distance is preferably set to allow a suitable space for the nipple. The pressure opening 103 may be integrated with the suction port 102, or may be fixed to an end of the suction port 102, which is not limited in this embodiment, for example, the suction port 102 is located at a tightening end of a trumpet-shaped opening of the suction cover 101, and the pressure opening 103 is connected to the suction port 102 through a screw thread.

The breast pump 10 provided by the embodiment of the present disclosure is provided with a pressure opening 103 at the position of the suction port 102, and the pressure opening 103 can be opened in a negative pressure state and closed in other states. In this way, the suction cup 101 can be attached to the surface of the breast while the breast pump 10 is in use, and the nipple can be aligned with the suction opening 102. Therefore, the pressure opening 103 is opened due to the negative pressure when the suction effect is applied, the breast is sucked, the breast milk can be sucked out and guided to the milk storage device through the suction opening 102 and the pressure opening 103, and when the suction effect disappears, the pressure opening 103 is closed again, so that the flow guide channel of the breast milk can be separated from the suction cover 101 and the suction opening 102, and the cleanness inside the breast pump 10 can be ensured.

Fig. 2a and 2b show exemplary structural illustrations of the pressure opening 103. Referring to fig. 2a and 2b, the pressure opening 103 comprises a sealing body 1031 and an opening 1032 in the center of the sealing body 1031. The sealing body 1031 may have a convex structure, and the opening 1032 may have a cross shape or a Y shape, but not limited thereto. Taking the cross-shaped opening as an example, when the pressure opening 103 is under negative pressure, four areas of the sealing body 1031 separated by the cross-shaped opening will all protrude further in the convex direction, so as to expand the pressure opening 103.

Furthermore, the sealing body 1031 of the pressure opening 103 may be made of silicone. Of course, the silica gel material should be a healthy material that can be applied to edible utensils. On the basis, since the silica gel has good flexibility, the pressure opening 103 is suitable for being prepared, so that the characteristics that the pressure opening 103 is opened under the action of negative pressure and closed under other states can be ensured, and a sufficiently long service life can be obtained.

In this example embodiment, as shown in fig. 3, the breast pump 10 further comprises an absorbent pad 104, the absorbent pad 104 being removably attached to an inner surface of the absorbent enclosure 101 to facilitate absorption of excess milk during use of the breast pump 10. Therefore, the absorption pad 104 can not only be attached to the surface of the nipple at the moment of stopping milk suction for absorbing the excessive milk, but also be directly detached and padded in the underwear at the end of milk suction to prevent the problem of milk overflow causing the need of wiping again, thereby avoiding the embarrassment of milk overflow. It should be noted that: for clarity of illustration of the various components of the breast pump 10, fig. 3 shows the structure of the absorbent pad 104 partially cut away so as to expose a portion of the absorbent casing 101.

Wherein, considering the problems of absorption effect and comfort, the present embodiment can adopt cotton material to prepare the cotton adsorption pad. Due to the good adsorbability and the soft characteristic of the cotton material, the embarrassment of galactorrhea can be timely solved, and comfortable experience is brought to mothers. It should be noted that: the absorbent pad 104 in this embodiment may be an accessory product configured specifically for the breast pump 10, but may be a commercially available spill-proof pad that has been further processed, and is not particularly limited as long as it has a suitable shape and can be applied to the inside of the absorbent cup 101.

As shown in fig. 4, the adsorption pad 104 includes an adsorption pad body 1041 and a slit 1042 located at the center of the adsorption pad body 1041. The position of the slit 1042 corresponds to the position of the suction port 102, so that the suction port 102 can be opened by the negative pressure when being opened. Further, the shape of the slits 1042 may also be the same as the shape of the opening 1032 in the pressure opening 103, e.g., all have a cross shape. In this way, the suction pad 104 is disposed on the inner surface of the suction cup 101, and the center thereof is provided with the slit 1042 corresponding to the position of the pressure opening 103, when the breast pump 10 is in a milk sucking state, due to the effect of negative pressure, the opening 1032 structure of the pressure opening 103 and the slit 1042 structure of the suction pad 104 are both opened in a direction away from the suction cup 101, so as to form a channel communicating the suction pad 104, the suction port 102, and the pressure opening 103, so as to facilitate the flow of breast milk, when the breast pump 10 is in a milk sucking state, both the opening 1032 structure of the pressure opening 103 and the slit 1042 structure of the suction pad 104 are closed, at this time, the suction pad 104 is attached to the surface of the breast, so as to wipe the nipple, and the suction pad 104 can be detached and disposed in the underwear at any time, thereby preventing the embarrassment of milk overflow. Based on the process, the design of the embodiment can effectively improve the convenience degree of the milk sucking process, thereby bringing good experience for mothers.

In this exemplary embodiment, as shown in fig. 5, the breast pump 10 further comprises a suction assembly 105, the suction assembly 105 being in communication with the suction port 102 for applying a negative pressure to the suction port 102 to expand the pressure opening 103 and draw out the breast milk.
