Due to the negative pressure, milk is discharged from the mammary gland, and flows from the other end of the diversion pipeline 1 to the one-way valve 29 through the connecting mechanism 27 in sequence, and the one-way valve 29 is closed. Then, the fluid driving mechanism inputs fluid from the bladder structure 2 through the through hole 5, so that the bladder structure 2 is expanded under the action of external fluid, at the moment, the sectional area of the flow guide pipeline 1 is reduced, the internal space of the flow guide pipeline 1 is reduced to generate positive pressure, under the action of the positive pressure, the areola 6 is withdrawn from the flow guide pipeline 1 and is blocked at the milk sucking port 3, the one-way valve 29 is opened under the positive pressure, and milk flows into the milk bottle 28 from the one-way valve 29. This is repeated so that milk is discharged from the mammary gland and milk is collected by the milk bottle 28. The one-way valve 29 has the function of simulating the milk sucking and the breath stopping of the baby.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
