A breast cup sealing structure and a breast pump

Abstract

This utility model relates to the field of maternal and infant feeding technology, specifically a milk bowl sealing structure, including a suction cup frame and a soft suction cup. The suction cup frame has a first elastic sealing structure, and the surface of the first elastic sealing structure is provided with a first sealing rib structure. The first elastic sealing structure is located on the inner side b of the suction cup frame, and the inner side b also has a fastening part, which extends and protrudes from the inner side b toward the first elastic sealing structure. The suction cup frame of this utility model has a first elastic sealing structure that can seal the installation position, which can improve the sealing effect of the milk bowl when installed on the breast pump. The first sealing rib structure elastically presses against the surface of the breast pump shell to form a sealing structure, so that the installation position can achieve a good watertight effect, which can prevent milk from leaking out and preventing milk residue from the installation gap, ensuring hygiene. On the basis of achieving a sealing and disassembly effect, it further ensures that a sufficient amount of milk can be poured out, making it convenient for users.
