The second negative pressure mechanism 40 is arranged, so that the breast milk suction assembly 110 can exert negative pressure on the breast milk passage 11 under the action of the manual power source, so as to realize the suction of the breast milk, and the suction capacity of the breast milk suction assembly 110 can be increased when the breast milk suction position is adjusted, so that the breast milk suction assembly 110 is not easily separated from the breast. Therefore, the breast milk suction assembly 110 of the utility model can exert negative pressure on the breast milk passage 11 through the first negative pressure mechanism 30 when the electric quantity is sufficient, so as to realize the suction of the breast milk, and the breast milk suction assembly 110 can exert negative pressure on the breast milk passage 11 through the second negative pressure mechanism 40 when the electric quantity is used up, so as to realize the suction of the breast milk, so that the situation that the breast milk cannot be normally sucked when the electric quantity is used up does not occur, and the use experience of the user is greatly improved.

[0046] Please refer to Figure 4 The first negative pressure mechanism 30 comprises a diaphragm 31 and a diaphragm support 32, the diaphragm 31 is connected to the diaphragm support 32, and a negative pressure chamber 33 is formed by the diaphragm support 32 and the diaphragm 31, the diaphragm support 32 is connected to one side of the milk storage container 20 facing the milk storage space 21, one side of the diaphragm 31 opposite to the negative pressure chamber 33 is communicated with the breast milk passage 11, and the diaphragm 31 is used to deform under the action of the electric power source. In the specific implementation, the diaphragm 31 deforms under the action of the electric power source, when the diaphragm 31 deforms towards the negative pressure chamber 33, the space on the side of the diaphragm 31 opposite to the negative pressure chamber 33 becomes larger, negative pressure is generated, and the suction of the breast milk is realized. In the embodiment, the diaphragm support 32 is connected to one side of the milk storage container 20 facing the milk storage space 21, the diaphragm 31 is connected to one end of the diaphragm support 32 away from the milk storage container 20, and one side of the diaphragm 31 opposite to the negative pressure chamber 33 is communicated with the breast milk passage 11.

[0047] In one embodiment, the diaphragm support 32 is integrally formed with the milk storage container 20. In this way, the processing and manufacturing are facilitated, and the production efficiency is improved. Of course, in other embodiments, the diaphragm support 32 and the milk storage container 20 can be respectively manufactured and then assembled.

[0048] Please refer to Figure 4 and Figure 5The second negative pressure mechanism 40 comprises an elastic pressing member 41, a first one-way valve 42 and a second one-way valve 43. The elastic pressing member 41 is connected to the milk storage container 20 to separate the milk storage space 21 from the outside, and the elastic pressing member 41 is used to deform under the action of a manual power source. The milk storage container 20 and / or the breast shield 10 is provided with a milk discharge port 50, which is connected to the outside and the milk storage space 21, and the first one-way valve 42 is installed at the milk discharge port 50 to allow the milk and gas to flow from the milk storage space 21 to the outside in one direction. The breast shield 10 is also provided with a communication hole 12, which is used to communicate the breast pumping channel 11 and the milk storage space 21, and the second one-way valve 43 is installed at the communication hole 12 to allow the milk and gas to flow from the breast pumping channel 11 to the milk storage space 21 in one direction.

In a specific implementation, when the power is used up, the elastic pressing member 41 is manually pressed to deform, and the elastic pressing member 41 deforms towards the side close to the milk storage space 21, so that the excess gas in the milk storage space 21 is discharged through the first one-way valve 42. When the elastic pressing member 41 is released, the elastic pressing member 41 rebounds and the first one-way valve 42 closes. Since the gas pressure in the milk storage space 21 is lower than the gas pressure in the breast pumping channel 11, the gas flows from the breast pumping channel 11 to the milk storage space 21 through the second one-way valve 43, and a negative pressure is generated in the breast pumping channel 11, thereby realizing the pumping of the milk.
