Description

Technical Field

[0001] The utility model relates to maternal and infant products, in particular to a convenient-to-use bilateral breast pump. Background Art

[0002] Existing breast pumps are usually lightweight and have only one milk suction component. For example, a breast pump disclosed in Chinese Patent No. ZL202311627009.0 includes: a breast shield, which includes a nipple channel for accommodating the nipple and a flange cover that fits against the breast; a negative pressure system that can directly or indirectly apply negative pressure to the breast shield; a power supply system that can supply power to the negative pressure system; a milk storage container that can store breast milk collected from the nipple channel; and a physiotherapy module that can apply a physiotherapy function to the breast. The physiotherapy module is electrically connected to the power supply system, and the physiotherapy module is detachably or removably arranged with the breast shield.

[0003] However, a single milk suction component can only be used for a single breast of the human body. If two breasts need to be used simultaneously, the user needs to purchase an additional breast pump. Moreover, if a host and a container are connected to each breast pump, wearing it on the body will appear bulky and increase the user's purchase cost. Therefore, further improvement is needed.
