Description

Technical Field

[0001] This application relates to the field of maternal and infant device technology, and particularly to breast pumps. Background Technology

[0002] Breast pumps are a common tool in infant care and breastfeeding support devices, widely used to help mothers collect and store breast milk. Traditional breast pump designs typically include a pump or manual operation unit to generate negative pressure, and a suction unit that contacts the breast. While these breast pumps meet basic functional needs, their design often results in a large footprint, making them inconvenient to carry and store.

[0003] Especially in today's fast-paced life, people have increasingly higher demands for the portability and miniaturization of products. Traditional breast pumps, due to structural design limitations, are often large in size, making them inconvenient to carry around and use daily. In particular, when out and about, traveling, or at work, users may need a small, lightweight, and easy-to-carry breast pump to meet their needs anytime, anywhere. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this application provides a breast pump that can solve the problem of the large size of breast pumps.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a breast pump, the breast pump comprising: a diaphragm support, wherein a negative pressure chamber is formed within the diaphragm support; a milk suction tube, wherein a milk guiding channel is formed within the milk suction tube, the milk suction tube is connected to the negative pressure chamber, and the milk guiding channel is at least used for guiding milk from the breast; wherein the milk suction tube and the diaphragm support are arranged side by side within the breast pump, and the diaphragm support is provided with a notch to avoid the milk suction tube, and the milk suction tube is at least partially embedded in the notch of the diaphragm support.

[0006] The notch is formed on the upper or lower side of the diaphragm support such that the vertical space occupied by the diaphragm support and the milk suction tube at least partially overlaps.

[0007] The diaphragm support has a milk flow port, which is used for the milk in the negative pressure chamber to flow into the milk storage space of the breast pump.

[0008] The diaphragm support has a groove formed on it that at least partially accommodates the milk flow port.

[0009] The milk flow port is provided with a one-way valve, which is at least partially accommodated in the groove. The one-way valve is configured to allow the milk to flow unidirectionally into the milk storage space.

[0010] The breast pump includes a milk bowl assembly with a milk storage space inside, and a diaphragm support is connected to the milk bowl assembly and extends into the milk storage space.

[0011] The milk suction tube is connected to the milk bowl assembly and extends into the milk storage space.

[0012] The milk bowl assembly includes a bowl body and a cover plate, which together form the milk storage space. The milk suction tube and the diaphragm support are both connected to the cover plate.

[0013] The milk suction tube and the diaphragm support are integrated with the cover plate.

[0014] The milk suction tube is located above the diaphragm support.

[0015] The breast pump further includes: a main unit having a through hole extending through the thickness direction; a breast shield having a narrow end and a wide end, the narrow end of the breast shield passing through the through hole, and the main unit being at least partially located between the wide end of the breast shield and the milk bowl assembly.

[0016] The main unit includes a horizontal portion and a vertical portion that is bent and connected to the horizontal portion. The through hole is provided on the vertical portion. The vertical portion is located between the wide end of the breast pump shield and the milk bowl assembly. The first side of the milk bowl assembly contacts the vertical portion of the main unit, and the second side of the milk bowl assembly contacts the horizontal portion of the main unit. The first side and the second side are two adjacent sides of the milk bowl assembly.

[0017] The breast pump also includes a diaphragm, which is placed inside the negative pressure chamber. The diaphragm divides the internal space of the diaphragm support into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface of the main unit, and the second subspace is connected to the internal space of the milk suction tube. The diaphragm can deform within the internal space of the diaphragm support under the negative pressure provided by the main unit to transmit negative pressure.

[0018] This application embodiment of the breast pump includes a diaphragm support and a milk suction tube. A negative pressure chamber is formed within the diaphragm support; a milk guiding channel is formed within the milk suction tube, which communicates with the negative pressure chamber. The milk guiding channel is at least used to guide milk from the breast. The milk suction tube and the diaphragm support are arranged side-by-side within the breast pump, and the diaphragm support has a notch to avoid the milk suction tube. The milk suction tube is at least partially embedded in the notch of the diaphragm support. Through this design, the diaphragm support and the milk suction tube are arranged side-by-side, and the notch on the diaphragm support avoids the milk suction tube, allowing the milk suction tube to be at least partially embedded in the notch. This design allows the milk suction tube to overlap in the horizontal or vertical directions, effectively reducing the overall size of the breast pump, making it more portable and easier to store, thus meeting the needs of modern mothers for miniaturized and convenient breast pumps.
