Description

Technical Field

[0001] The utility model relates to the technical field of mother and baby products, and more specifically, to a wearable breast pump. Background Art

[0002] A breast pump refers to a tool used to extract breast milk accumulated in the mammary glands. It is generally applicable when the baby cannot directly suck breast milk, or when there are problems with the mother's nipples, or when the mother still hopes to breastfeed despite insisting on working.

[0003] Based on the above, the inventor found that most of the existing products on the market are four-piece sets. This design integrates the cylinder and the cup cover through the production process, which is convenient for users to assemble with good sealing performance. In addition, most breast pumps on the market do not have a designed milk storage space, resulting in the user having to keep the upper body upright or leaning forward during use to avoid the backflow of milk at the milk suction port, which makes the use experience unfriendly and fatigue appears. At the same time, for the convenience of use and space limitation, most existing breast pumps use a diaphragm pump with a relatively small size for the air pump design. However, this brings problems such as unstable product function output and high noise, and the use experience is not smooth. Therefore, in view of this, the existing structure is studied and improved to provide a wearable breast pump in order to achieve a more practical value. Summary of the Utility Model

At the same time, the added milk storage chamber solves the fatigue caused by keeping the body upright or leaning forward during use. In addition, the use of a piston pump in cooperation with an air valve greatly improves the stability of function output and reduces the noise generated during its use, making the use experience smoother.
