[0002] In the current market of breastfeeding products, as an important tool for assisting mothers in collecting breast milk, the optimization of the design and function of breast pumps has always been the focus of product developers. The traditional design of breast pumps often focuses on the combination of functionality and portability, but there is still room for improvement in meeting specific user needs, such as enhancing the usage efficiency and comfort. Especially, the milk bowl assembly, as the part that directly contacts and stores breast milk, its structural design directly affects the milk collection efficiency and the actual experience of users.
[0003] Currently, the milk bowl designs of most breast pumps on the market are relatively standard. While pursuing overall compactness, they often neglect the optimization of the volume of the lower half of the milk bowl. This limitation may lead to the following problems during actual use: First, the smaller volume of the lower half restricts the amount of breast milk that can be collected in a single use, increasing the frequency of emptying and reassembling, and affecting the convenience of use for mothers; Second, for mothers with a large milk secretion volume, the smaller volume may not be sufficient to handle the rapid secretion situation, resulting in overflow or waste; Finally, the unreasonable volume distribution may also affect the negative pressure stability and efficiency during the milk collection process, reducing the overall milk collection experience.

[0026] In this embodiment, the breast pump includes a main body 20 and a milk bowl assembly 10.
[0027] The main body 20 includes a horizontal portion 21 and a vertical portion 22 bent and connected to the horizontal portion 21. The angle between the extending directions of the horizontal portion 21 and the vertical portion 22 is approximately 90 degrees, but the embodiments of the present application do not limit this, as long as they are bent and extended in a way that is acceptable.
[0028] The first side surface S1 of the milk bowl assembly 10 contacts the vertical portion 22 of the main body 20, and the second side surface S2 of the milk bowl assembly 10 contacts the horizontal portion 21 of the main body 20. The first side surface S1 and the second side surface S2 are two adjacent side surfaces of the milk bowl assembly 20.
[0029] In the above manner, the main body 20 is generally L-shaped, forming an L-shaped step, and the milk bowl assembly 10 is accommodated at the L-shaped step of the main body. This layout is beneficial to the miniaturization and thinning of the overall breast pump, and is also convenient for the layout of the internal space of the main body. It enables the components of the breast pump to be closely assembled together, with a reasonable layout, effectively reducing the volume of the entire breast pump, and thus facilitating carrying and use, and improving the user experience.
[0030] In this embodiment, the thickness of the upper half of the vertical portion 22 of the main body 20 is greater than the thickness of the lower half of the vertical portion 22 of the main body 20. In some embodiments, the thickness of the upper half may refer to the average thickness of each position of the upper half in the height direction, and the thickness of the lower half refers to the average thickness of each position of the lower half in the height direction.
[0031] In the above manner, on the one hand, this is beneficial to the layout of the internal components of the main body 20. The sizes of the internal components of the main body are often inconsistent. The internal components of the main body, such as a negative pressure pump, a solenoid valve, a battery, a circuit board, etc. Therefore, the components with larger sizes can be arranged above, and the components with smaller sizes can be arranged below. On the other hand, without changing the overall thickness of the breast pump, the thickness of the lower half of the milk bowl assembly can be made thicker, thereby increasing the volume of the lower half of the milk bowl assembly, which can reduce the probability of milk covering components such as the one-way valve or the milk outlet inside the milk bowl assembly, improving the milk extraction efficiency and reducing the milk extraction energy consumption and the risk of backflow. On the third hand, it can make the milk bowl assembly and the main body stagger each other, which is more convenient for the up-down, left-right limit design between the milk bowl assembly and the main body.
[0032] In one embodiment, the thickness of the longitudinal portion 22 of the main body 20 gradually decreases from top to bottom.
[0033] In one embodiment, the thickness of the upper half of the milk bowl assembly 10 is less than the thickness of the lower half of the milk bowl assembly 10.
[0034] In one embodiment, the thickness of the milk bowl assembly 10 gradually increases from top to bottom.
[0035] In one embodiment, the thickness of the transverse portion 21 of the main body 20 gradually decreases along the direction towards the connection between the transverse portion 21 and the longitudinal portion 22.
[0036] In one embodiment, the surface of the transverse portion 21 of the main body 20 in contact with the milk bowl assembly 10 is non-planar. For example, the upper surface of the transverse portion 21 of the main body 20 bulges towards the second side surface S2 of the milk bowl assembly 10, and the upper surface of the transverse portion 21 of the main body 20 is curved. On the one hand, this can increase the contact area between the main body 20 and the milk bowl assembly 10, facilitating heat dissipation of the main body 20 by the milk and water in the milk bowl assembly 10. This curved surface shape is not limited to a smoothly transitioning curved surface, but can also be a non-smoothly transitioning curved surface, such as a surface with an angular bend transition, a serrated surface, a wavy surface, etc. The shape of the second side surface S2 of the milk bowl assembly 10 generally matches the shape of the upper surface of the transverse portion 21. On the other hand, this non-planar design can also facilitate the limit design in the transverse direction between the main body 20 and the milk bowl assembly 10, and is easier to position during installation.
[0037] In one embodiment, a through hole penetrating the thickness direction is formed in the longitudinal portion 22 of the main body 20; the breast pump further includes a breast shield 30, the breast shield 30 has a narrow end and a wide end, the narrow end of the breast shield 30 is inserted through the through hole, and at least a part of the main body 20 is located between the wide end of the breast shield 30 and the milk bowl assembly 10.
[0038] In one embodiment, the milk bowl assembly 10 includes a bowl body 11 and a cover plate 12, the bowl body 11 and the cover plate 12 enclose to form a milk storage space, the breast pump further includes a milk suction pipe 40 and a diaphragm bracket 50, a negative pressure chamber is formed in the diaphragm bracket 50, and both the milk suction pipe 40 and the diaphragm bracket 50 are connected to the cover plate 12.
[0039] In one embodiment, the milk suction pipe 40 is located above the diaphragm bracket 50.
[0040] In one embodiment, the breast pump further includes a diaphragm 60 for being placed in the negative pressure chamber. The diaphragm 60 divides the inner space of the diaphragm bracket 50 into a first sub-space and a second sub-space. The first sub-space is communicated with the negative pressure interface 23 of the main body 20, and the second sub-space is communicated with the inner space of the milk suction pipe 40. The diaphragm 60 can be deformed in the inner space of the diaphragm bracket under the negative pressure provided by the main body to transmit the negative pressure.
[0041] In the embodiment of the present application, the breast pump is provided to include: a main body including a horizontal part and a vertical part bent and connected to the horizontal part; the thickness of the upper half of the vertical part of the main body is greater than the thickness of the lower half of the vertical part of the main body; a milk bowl assembly, a first side surface of the milk bowl assembly contacts the vertical part of the main body, and a second side surface of the milk bowl assembly contacts the horizontal part of the main body. The first side surface and the second side surface are two adjacent side surfaces of the milk bowl assembly. It can increase the capacity of the lower half of the milk bowl, without additionally increasing the overall thickness of the breast pump, and can more conveniently arrange the internal components of the main body.
