Meanwhile, the milk collecting device 3 can connect the breast pump host 1 and the milk storage bottle 2 into a whole, thereby playing the function effect of starting and stopping, and further leading the volume of the breast pump to be thinner and smaller.

The air bag 31 is made of liquid silica gel made of food-grade materials, has excellent elasticity and fatigue resistance, and is mainly used for isolating air pressure from breast milk. As shown in fig. 10 and 11, the air bag 31 has a flat U shape, and the air pressure end is provided in a flat U shape conforming to the air bag 31. The wide surface of the air bag 31 is arranged right opposite to the breast pumping end, the thickness between the two wide surfaces is small, the thinness of the whole breast pump is favorably reduced, and a breast-feeding mother can conveniently wear the breast pump and the breast shield. Meanwhile, the distance between the two narrow surfaces of the air bag 31 is larger, which is beneficial to increasing the volume of the whole air bag 31, and further increasing the increasing range of the air pressure difference in the whole tee joint 32, so as to provide sufficient pressure for sucking milk. The air bag cover is provided with deformation guide surfaces which are arranged corresponding to the two narrow surfaces of the air bag 31, and the deformation guide surfaces guide the air bag 31 to deviate from the breast to be attached to the breast under the vacuum negative pressure to form a flat shape. As shown in fig. 7, when the air bag 31 is flattened by negative pressure, the whole air bag 31 deviates from the breast, and further the gap between the breast and the air bag 31 is increased, so that the milk can smoothly flow into the milk flowing end from the tee 32. The deformation guide surface can be specifically set as a folded surface attached to the surface of the airbag 31, and the folded part of the folded surface is vertically deviated from the airbag 31, so that the deviation guide of the whole airbag 31 is realized.

Fig. 6 and 7 show two states of the air bag 31 when the breast pump is in operation, respectively. In fig. 6, the air bag 31 is in a natural state, at this time, the release valve 14 is in an open state, the air bag 31 is communicated with the atmospheric pressure, no negative pressure is formed in the tee joint 32, and the whole breast pump is in a release state, which is mainly for facilitating the milk to smoothly flow into the milk storage bottle 2; in fig. 7, the air bag 31 is in a negative pressure attaching state, at this time, the air release valve 14 is in a closed state, the air bag 31 is only communicated with the vacuum pump 13 and is completely vacuumized, negative pressure is formed in the tee joint 32 due to the reduction of the volume of the air bag 31, and the whole breast pump is in a suction state, so that the milk in the breast is sucked out.

The duckbill valve 33 is arranged at the milk flowing end and has the function of preventing backflow. As shown in fig. 12, the duckbill valve 33 is provided with a first valve 331 and a second valve 332, the first valve 331 includes arc-shaped first deformable walls 3311 at two sides thereof, the two first deformable walls 3311 gradually get close from top to bottom and form a long first cut 3312 at the end, and the first valve 331 is connected to the milk end and the milk bottle 2; the second valve 332 comprises arc-shaped second deformable walls 3321 at two sides of the second valve, the two second deformable walls 3321 gradually get close from top to bottom and form a long second notch 3322 at the tail end, and the second valve 332 is communicated with the outside atmosphere and the milk bottle 2. The duckbill valve 33 is made of liquid silica gel made of food grade materials, and has the characteristics of excellent sealing property, tear strength, rebound resilience, yellowing resistance, thermal stability, thermal aging resistance and compression deformation resistance. The wall thickness of the first deforming wall 3311 and the second deforming wall 3321 is 0.4-0.6 mm, the area of the deforming wall is large and thin, and the deformation is easy to rebound and deform under stress.

Switching of the opened and closed states of the first and second cutouts 3312 and 3322 is easily achieved by the deformation of the first and second deforming walls 3311 and 3321. The second valve 332 is connected to the outside atmosphere, and the second deformable wall 3321 is not pressed by the negative pressure, so that it is normally open, and the milk bottle 2 is kept in a ventilation state, and the milk can continuously flow into the milk bottle 2 through the first cut 3312; and the first valve 331 is opened or closed following the switching between the vacuum negative pressure and the normal pressure. When the tee 32 is relieved of negative pressure, the first notch 3312 is opened and milk flows into the milk bottle 2 immediately. When the milk bottle 2 shakes, the milk presses the first deforming wall 3311 and the second deforming wall 3321 from the outside, so that the first notch 3312 and the second notch 3322 are closed, the milk cannot flow out of the milk bottle 2, and the milk is effectively prevented from leaking and flowing backwards.

Preferably, the first valve 331 and the second valve 332 are connected together to a sealing gasket 333, the first cut-out 3312 and the second cut-out 3322 are both directed to the inner cavity of the milk storage bottle 2, and the periphery of the sealing gasket 333 is in sealing engagement with the port of the milk storage bottle 2. When the milk storage bottle 2 is in threaded connection with the milk flowing end, the port of the milk storage bottle 2 is tightly abutted to the lower side face of the sealing gasket 333, meanwhile, the threaded connection mode can provide pressure to enable the upper side face of the sealing gasket 333 to be tightly attached to the milk flowing end, and the sealing connection between the milk flowing end and the milk storage bottle 2 is effectively guaranteed. Meanwhile, a first air pressure chamber and a second air pressure chamber which are separated from each other are formed in the middle of the sealing gasket 333, a first connection portion inserted into the first air pressure chamber and a second connection portion inserted into the second air pressure chamber are respectively formed at the milk flowing end, the first valve 331 is disposed at the lower end of the first air pressure chamber, the second valve 332 is disposed at the lower end of the second air pressure chamber, the first air pressure chamber is communicated with the milk flowing end, and the second air pressure chamber is communicated with the external atmospheric pressure. The first air pressure cavity is connected with the first connecting part in an interference fit manner, the second air pressure cavity is connected with the second connecting part in an interference fit manner, and valve failure caused by excessive deformation of the upper end parts of the first valve 331 and the second valve 332 can be avoided.

Figures 8 and 9 show a schematic view of the state of the first valve 331 in the duckbill valve 33 when the breast pump is in operation. In fig. 8, the air bag 31 is in a natural state, the inside of the tee 32 is at a normal pressure, the first cut 3312 is naturally in an open state, and milk collected at the milk end flows into the milk storage bottle 2 through the first valve 331; in fig. 9, the air bag 31 is in a negative pressure fit state, the tee 32 is in a negative pressure state, the first notch 3312 is in a closed state under the extrusion of the negative pressure, and the sucked milk is converged to the milk flowing end and stays at the front end of the first valve 331.
