Description

FIELD OF THE DISCLOSURE

The present disclosure relates to the technical field of breast pumps, and more particularly to a breast pump wearable in a bra.

BACKGROUND OF THE DISCLOSURE

A breast pump is a device that extracts milk from the breasts of a nursing woman. A breast pump wearable in a bra is an all-in-one breast pump that integrates a suction generating device, a milk collection device and a breast shield, as a wearable breast pump in an independent bra disclosed in CN216798371 U, for example. The breast pump wearable in a bra can be used in the bra as a whole, and the user does not need to take off the clothes or enter a specific position when pumping breast milk, so the breast pump wearable in a bra has the advantage of being convenient to use in public places such as offices.

In the above-mentioned patent document, the holding part of the diaphragm is arranged on the breastshield, and the holding part and the lower part of the diaphragm jointly form a milk-side vacuum chamber, and an air-side vacuum chamber is defined by a concave part arranged in the housing of the breast pump and a upper part of the diaphragm. When working, the air pump drives the diaphragm to create a negative pressure inside the breastshield to simulate the suction generated when a nursing woman is feeding a child. Since the diaphragm in the above-mentioned patent document is jointly fixed by the breastshield and the breast pump housing, the fixation of the diaphragm is released when the breastshield is disassembled. Therefore, when the breastshield is put back again, an aligning operation of the diaphragm and the holding part of the diaphragm and an aligning operation of the diaphragm and the concave part on the housing of the breast pump are required. The breastshield needs to be disassembled and cleaned frequently because it contains a milk channel, which makes the cleaning and maintenance operations of the breast pump more complicated.
