Description

Technical Field

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

[0002] In the current breastfeeding product market, breast pumps serve as an important tool to assist mothers in collecting breast milk. In the field of maternal and infant care, breast pumps play a crucial role in ensuring infant nutrition, relieving milk stasis in mothers, and facilitating breast milk storage. With technological advancements and increasingly refined market demands, breast pump designs are constantly evolving towards greater user-friendliness, convenience, and efficiency.

[0003] Traditional breast pumps often suffer from problems such as cumbersome installation, easy displacement during use, and insufficient stability. These issues not only affect the mother's comfort but may also lead to low milk pumping efficiency and even unnecessary leakage during operation, impacting the user experience. For working women who need to pump frequently, a well-designed, portable breast pump that ensures a tight seal is particularly important. Utility Model Content

[0026] In this embodiment, the breast pump includes a main unit 20 and a milk bowl assembly 10.

[0027] The host 20 includes a horizontal portion 21 and a vertical portion 22 that is bent and connected to the horizontal portion 21.

[0028] The first side S1 of the milk bowl assembly 10 contacts the longitudinal portion 22 of the main unit 20, and the second side S2 of the milk bowl assembly 10 contacts the transverse portion 21 of the main unit 20. The first side S1 and the second side S2 are two adjacent sides of the milk bowl assembly 10. By setting the main unit 20 to a roughly bent L-shape, the stability of the assembly between the milk bowl assembly 10 and the main unit 20 can be improved.

[0029] A first coupling structure 211 is provided on the transverse portion 21, and a second coupling structure 111 matching the first coupling structure 211 is provided on the second side S2 of the milk bowl assembly 10. The first coupling structure 211 and the second coupling structure 111 are configured to be detachably coupled to each other to realize the installation or positioning between the main unit 20 and the milk bowl assembly 10. By providing the first coupling structure 211 and the second coupling structure 111 on the transverse portion 21 of the main unit 20 and at corresponding positions on the milk bowl assembly 10, the stability of the assembly between the milk bowl assembly 10 and the main unit 20 can be further improved. The first coupling structure 211 and the second coupling structure 111 can be complementary coupling structures, for example, one of which is a slot and the other is a buckle, as described below.

[0030] In one embodiment, a third coupling structure 221 is provided on the longitudinal portion 22, and a fourth coupling structure 112 matching the third coupling structure 221 is provided on the first side surface S1 of the milk bowl assembly 20. The third coupling structure 221 and the fourth coupling structure 112 are configured to be detachably coupled to each other to realize the installation or positioning between the host 20 and the milk bowl assembly 10. The first coupling structure 211 and the second coupling structure 111 can be complementary coupling structures, for example, one of which is a slot and the other is a buckle.

By providing one coupling point on the transverse portion 21 and two coupling points on the longitudinal portion, the stability of installation and positioning can be improved, and disassembly and installation can be made smoother.

[0032] In one embodiment, the lines connecting the positions of the two third coupling structures 221 and the one first coupling structure 112 form a triangle. By arranging the three coupling points in a triangular relationship, the stability of the installation and positioning can be improved.

[0033] In one embodiment, one of the first coupling structure 211 and the second coupling structure 111 is an elastic buckle, and the other is a slot.

[0034] In one embodiment, the first coupling structure 211 is an elastic buckle, and the second coupling structure 111 is a slot. The surface of the elastic buckle 211 facing the milk bowl assembly 10 has an inclined surface that slopes upward along the direction close to the longitudinal portion 22. By providing an inclined surface on the elastic buckle 211, the main unit 20 and the milk bowl assembly 10 can be smoothly installed and positioned.

[0035] In this configuration, one of the third coupling structure 221 and the fourth coupling structure 112 is a protrusion, and the other is a groove.

[0036] Optionally, the third coupling structure 221 is a protrusion 221, and the fourth coupling structure 112 is a groove.

[0037] Among them, a ball is provided on the side of the protrusion 221 facing the horizontal portion 21 of the host 20.

[0038] The milk bowl assembly 10 includes a bowl body 11 and a cover plate 12, which together form a milk storage space. The second coupling structure 111 is disposed on the bowl body 11. The breast pump also includes a milk suction tube 40 and a diaphragm support 50. A negative pressure chamber is formed within the diaphragm support 50. Both the milk suction tube 40 and the diaphragm support 50 are connected to the cover plate 12.

[0040] In one embodiment, the breast pump further includes a diaphragm 60, which is placed inside the negative pressure chamber. The diaphragm 60 divides the internal space of the diaphragm support 50 into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface 23 of the main unit 20, and the second subspace is connected to the internal space of the milk suction tube 40. The diaphragm 60 can deform within the internal space of the diaphragm support under the negative pressure provided by the main unit to transmit negative pressure.
