The flange 12 is made of a flexible material, such as rubber or silicone, etc. When negative pressure is applied to the flange 12, the flange 12 can be deformed to transmit the negative pressure to the user's breast, further improving the milk discharge efficiency. The milk storage container 3 can be a milk bag, a milk bottle or a milk bowl, etc. The milk storage container 3 can be directly connected to the breast shield 1, or can be connected through a shorter pipe, or the milk bowl can surround the breast shield 1 to form an independent wearing unit; the two can be an integral whole, or a detachable structure, or the milk bowl or milk bottle can be connected to a shell respectively, but the channel between the two is connected, so that breast milk can flow from the breast shield 1 into the milk storage container 3. The side of the nipple receiving portion 11 facing away from the breast shield 1 is integrally formed with a check piece 2, which is integrally formed to prevent the small parts of the check piece 2 from being lost, and the breast shield 1 and the check piece 2 can be cleaned at the same time, reducing the number of cleaning times for the user. Under the action of negative pressure, the check piece 2 is sealed and fitted to the milk outlet 112 of the nipple receiving portion 11 to achieve blocking of the milk flow path.

[0031] The milk collection assembly 100 proposed in the technical solution of the utility model comprises a breast shield 1, a check piece 2 and a milk storage container 3. The breast shield 1 comprises a flange 12 and a nipple receiving portion 11. One side of the flange 12 is used to fit the breast, and the other side is connected to the nipple receiving portion 11. The nipple receiving portion 11 is formed with a milk suction channel 111. The side of the nipple receiving portion 11 away from the flange 12 is formed with a milk flow port 112 of the milk suction channel 111, forming a milk flow path. The check piece 2 is integrally formed with the other opening of the nipple receiving portion 11, and can seal the milk flow port 112 when negative pressure is applied, so as to unidirectionally conduct the milk flow path. The check piece 2 is integrally formed with the other opening of the nipple receiving portion 11, and can be cleaned or installed together, so as to prevent the check piece 2 from being lost, which would cause the milk collection assembly 100 to be unusable.

[0032] In one embodiment of the present application, the check member 2 includes an elastic connecting portion 21 and a sealing portion 22, the elastic connecting portion 21 is connected between the nipple receiving portion 11 and the sealing portion 22, and the elastic connecting portion 21 can be elastically deformed so that the sealing portion 22 seals the milk flow port 112 when negative pressure is applied, and allows milk to flow through the milk flow port 112 after the negative pressure is released.

[0033] In this embodiment, the elastic connecting part 21 is made of elastically deformable material, such as silicone or rubber. One end of the elastic connecting part 21 is connected to the outer peripheral wall of the nipple accommodating part 11, and the other end is connected to the sealing part 22. By manually pulling the elastic connecting part 21, the elastic connecting part 21 can be deformed, so that the sealing part 22 can seal the milk outlet under the action of negative pressure, thereby preventing the milk from being sucked back into the breast shield 1 under the action of negative pressure, so as to contaminate the milk.

[0034] In one embodiment of the present application, a snap-fitting piece 113 is provided on the nipple receiving portion 11, and a snap-fitting hole 23 is opened on the check member 2. The elastic connecting portion 21 can be elastically deformed so that the snap-fitting piece 113 is snapped into the snap-fitting hole 23, so that the sealing portion 22 seals the milk flow port 112 when negative pressure is applied, and milk can flow through the milk flow port 112 after the negative pressure is released.

[0035] In this embodiment, a clamping piece 113 is provided on the nipple accommodating portion 11, and a clamping hole 23 is opened on the check member 2.
