The utility model relates to a bionic infant nipple which comprises a horn part attached to the horn inner wall of a breast suction cover, a nipple neck part penetrating into the breast suction cover and sealed with the breast suction end of a three-way connecting part and a nipple head part located in the three-way connecting part, and the whole or part of the nipple head part is a deformation body capable of simulating the
breast milk suction action of an infant. A milk sucking hole is formed in the deformation body, and the milk sucking hole is opened or closed based on the
simulation action of the deformation body along with the change of the milk sucking negative pressure. On one hand, the nipple is formed based on the horn part, the nipple neck part and the nipple head part, the nipple can be conveniently and stably assembled on a
breast pump, the
breast milk sucking action of a baby is simulated based on the deformation body of the nipple head part along with the adsorption pressure change,
milk secretion is promoted, and discomfort of mothers is relieved; and on the other hand, the designed milk sucking hole is switched between opening and closing, and the nipple is used as a one-way valve, so that the milk sucking device can be applied to milk sucking in various postures, and the universality and the practicability are improved.
