1. A breast pump adapted to be placed at a mammary gland of a breast of a user to collect breast milk, wherein the breast pump comprises:
a main body having an accommodation space;
a breast milk suctioning shield assembled in the accommodation space and detachably connected to the main body, wherein a front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion;
at least one deformable member assembled with an annular connection portion located between the breast shielding portion and the nipple passage, and the at least one deformable member is controlled to be inflated and deflated by a first air pump;
a breast milk container assembled with the main body; and
a first detector disposed in the breast pump, wherein when the first detector detects none of the breast milk inside the nipple passage, a negative-pressure suctioning force generated by a second air pump decreases,
wherein the first detector is disposed at a rear portion of the nipple passage of the breast milk suctioning shield to detect the breast milk inside the nipple passage; when the first detector detects none of the breast milk inside the nipple passage, the first detector enables the first air pump to inflate and deflate the at least one deformable member alternately to press and touch the breast.
