The rear opening of the breast cup portion 120 is connected to the milk suction port 141, and the front opening edge of the breast cup portion 120 extends outward to form the outer ring portion 130; the airbag 200 is installed in the airbag cavity 150; the milk storage shell 300 has a front opening 301, the main body 110 is installed in the milk storage shell 300, and the outer ring portion 130 is hermetically installed at the front opening 301. A channel pipe 310 is provided on the milk storage shell 300, and the channel pipe 310 is located above the airbag 200; the main unit 400 is installed on the top of the milk storage shell 300, and the channel pipe 310 extends into the main unit 400. The main unit 400 includes a negative pressure assembly 410, and the negative pressure assembly 410 is connected to the channel pipe 310 through a pipeline.

[0028] First, when a woman uses this breast pump, fix the bra part 120 on the breast and fix the breast pump through the bra, so that the breast pump is closely attached to the breast, without the need to hold the collection container, and at the same time achieve invisible wearing; second, when cleaning, the main body 110 can be first detached from the milk storage shell 300, and then the three-way part 100 can be detached from the milk storage shell 300, so that the inside of the milk storage shell 300 is completely exposed, and the inside of the milk storage shell 300 and the three-way part 100 can be fully cleaned to ensure the hygiene of use.

[0029] In this embodiment, the inner wall of the central cavity 140 includes a diversion inner wall 160. The diversion inner wall 160 is located between the milk suction port 141 and the milk discharge port 142, and the diversion inner wall 160 is used to guide part of the milk in the central cavity 140 into the milk discharge port 142; the diversion inner wall 160 has three implementation manners:

[0030] Refer to Figure 4 As shown, Embodiment 1: The diversion inner wall 160 is an inclined surface.

[0031] Refer to Figure 5 As shown, Embodiment 2: The diversion inner wall 160 is an inclined arc surface.

[0032] Refer to Figure 6 As shown, Embodiment 3: The diversion inner wall 160 is divided into a first inner wall part 161, a second inner wall part 162, and a third inner wall part 163. The first inner wall part 161 and the second inner wall part 162 are vertically arranged, and the third inner wall part 163 horizontally connects the first inner wall part 161 and the second inner wall part 162.

[0033] Refer to Figure 1. Since during milk suction, the airbag 200 intermittently depresses upward to generate negative pressure in the central cavity 140, it is necessary to keep the airbag 200 firmly installed during operation. Therefore, a first hook ring 151 is provided at the outer edge of the opening of the airbag cavity 150, and a second hook ring 210 is provided on the airbag 200. The second hook ring 210 cooperates with the first hook ring 151.

[0034] To further enhance the firmness of the installation, a pressure ring 320 is installed on the top inner wall of the milk storage shell 300 of the airbag 200. The outer wall of the pressure ring 320 presses the airbag 200 against the inner wall of the airbag cavity 150, thereby forming a sealed space 101.
