[0028] In this embodiment, the diaphragm assembly of the breast pump includes a diaphragm 10, a diaphragm cover 20, a sealing structure 30, and a sealing layer 40.

[0029] The diaphragm 10 has a cavity 11 and an opening 12 communicating with the cavity 11.

[0030] The diaphragm cover 20 is used to cover the opening 12 and is provided with a through hole 21 therethrough.

[0031] The sealing structure 30 is disposed around the through hole 21 and is configured to form a seal with the main body of the breast pump when the diaphragm cover 20 abuts against the main body of the breast pump.

[0032] By providing the sealing structure 30 at the contact portion between the diaphragm cover 20 and the main body of the breast pump, this design ensures that when the breast pump is operating, the main body and the diaphragm cover 20 are closely fitted and can also form a reliable sealing effect, effectively preventing air leakage and contamination.

[0033] As an implementation manner, a sealing layer 40 is provided on the surface of the diaphragm cover 20 facing away from the diaphragm 10. By providing the sealing layer 40, a secondary seal is formed to further ensure the sealing property.

[0034] As an implementation manner, the sealing layer 40 and the sealing structure 30 are integrally formed. The sealing layer 40 on the diaphragm cover 20 does not cover the through hole 21, and the sealing layer 40 extends around the through hole 21 to form the sealing structure 30. The height of the sealing structure 30 protruding from the diaphragm cover 20 is greater than the thickness of the sealing layer 40.

[0035] As an implementation manner, the diaphragm cover 20 is made of a hard material, and the sealing layer 40 is made of a soft material.

[0036] As an implementation manner, the sealing structure 30 is a trumpet-shaped suction cup. The narrow end of the suction cup communicates with the through hole 21, and the wide end of the suction cup is configured to form a seal with the main body of the breast pump when the diaphragm cover 20 abuts against the main body of the breast pump.

[0037] As an implementation manner, a groove 22 is formed on the diaphragm cover 20, and the groove 22 is configured to facilitate the user to remove the diaphragm cover 20 from the opening 12.

[0038] As an implementation manner, the number of the grooves 22 is two, and the two grooves 22 are respectively located on opposite sides of the through hole 21. For example, the grooves 22 are used to accommodate the fingers of the user, so that the user can pinch the diaphragm cover 20 through the grooves 20 to open the diaphragm cover 20.

[0039] As an implementation manner, the diaphragm assembly further includes a connecting member 50. One end of the connecting member 50 is connected to the diaphragm 10, and the other end is connected to the diaphragm cover 20. In one implementation manner, the diaphragm cover 20, the diaphragm 10, and the connecting member 50 can be integrally formed, and the connecting member 50 can be bent so that the diaphragm cover 20 can be turned over to open or close.

[0040] In the above manner, connecting the diaphragm cover 20 and the diaphragm 10 into one body can reduce the number of parts of the breast pump and avoid loss of parts.

[0041] As an implementation manner, the connecting member 50 is disposed on the long side edge of the opening 12 of the diaphragm 10. By disposing the connecting member 50 on the long side edge of the opening 12 of the diaphragm 10, the connection stability between the diaphragm 10 and the diaphragm cover 20 can be improved, and the service life of the diaphragm assembly can be extended.

[0042] Please continue to refer to Figure 4 and Figure 5 , Figure 4 which is a schematic structural diagram of the breast pump according to the embodiment of the present application. Figure 5 which is a schematic exploded structural diagram of the breast pump according to the embodiment of the present application.

[0043] The embodiment of the present application further provides a breast pump, which includes the diaphragm assembly 90 of any one of the above embodiments. The breast pump includes a main body 60. An air hole communicating with the through hole 21 connecting the diaphragm assembly is formed on the main body 60. A negative pressure pump is disposed in the main body 60, and the negative pressure pump communicates with the air hole. Specifically, a tracheal joint 65 is formed on the main body 60, the air hole is formed in the tracheal joint 65, and the tracheal joint 65 is inserted into the through hole 21.

[0044] In some implementation manners, the diaphragm 10 can be made of an elastic material, which can be deformed under the negative pressure of the negative pressure pump of the main body 60 to transmit the negative pressure. The diaphragm 10 is used for air-liquid isolation between the negative pressure interface side of the main body 60 and the milk suction side of the breast pump, to avoid the milk flowing back into the main body 60 and causing damage or pollution to the main body 60. At the same time, the diaphragm 10 is also used to prevent air from entering the milk suction side and polluting the milk.

The vertical portion 62 is located between the wide end of the breast milk shield 80 and the milk bowl assembly 70. A first side surface of the milk bowl assembly 70 contacts the vertical portion of the main body 60, and a second side surface of the milk bowl assembly 70 contacts the horizontal portion of the main body 60.
