Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of mother and baby products, and particularly to a breast pump and a breast milk shield. Background Art
[0002] In the actual application of breast pumps, especially during the process of pouring out the breast milk stored inside, problems such as unsmooth milk pouring often occur due to the combined action of pressure difference and liquid surface tension. Specifically, when breast milk attempts to flow out from the milk storage space through the milk pouring port, surface tension will cause the liquid to form a continuous film. This phenomenon is particularly obvious, especially at the beginning and end of milk pouring, resulting in blocked milk flow, which not only affects the smoothness of milk pouring but also may cause waste of breast milk and unsanitary conditions during milk pouring. In addition, if the design of the milk pouring port lacks consideration of fluid dynamics, the uneven pressure difference will also exacerbate the unsmoothness of milk pouring, making the milk pouring process time-consuming and laborious.

[0025] Please refer to Figures 1-4 , Figure 1 which is a schematic structural diagram of the breast pump according to the embodiment of this application. Figure 2 which is a schematic diagram of the shapes of the milk pouring port and the notch according to the embodiment of this application.

[0026] In this embodiment, a milk storage space 101 is formed inside the breast pump. A milk pouring port 102 is formed on the breast pump. The milk pouring port 102 is used to communicate the milk storage space 101 with the outside. A notch 103 is formed at the edge 80 of the milk pouring port 102. The notch 103 communicates with the milk pouring port 102. The size of the notch 103 in the direction where the edge 80 is located is smaller than the size of the milk pouring port 102 in the direction where the edge 80 is located.
[0027] Milk storage space 101: A dedicated milk storage space 101 is provided inside the breast pump. This is to facilitate the collection and temporary storage of breast milk until the next step of processing (such as refrigeration or direct feeding to the baby). Such a design allows the mother to directly store the milk after milk pumping without additional transfer, reducing the operation steps and also reducing the risk of contamination.
[0028] Milk pouring port 102: The milk pouring port 102 equipped on the breast pump is a key design. It serves as a channel for communicating the milk storage space 101 with the outside, facilitating the user to pour the stored breast milk into a milk bottle or other containers when needed. This design simplifies the process of breast milk transfer and improves the flexibility of use.
[0029] Notch 103 design: The edge 80 of the milk pouring port 102 is specifically designed with a notch 103, and this notch 103 communicates with the milk pouring port 102. This detailed design may be to facilitate controlling the flow rate during milk pouring, preventing splashing or waste caused by too fast a flow rate of breast milk during the milk pouring process. At the same time, this design may also consider the convenience of cleaning, facilitating the thorough removal of residual milk during cleaning to maintain the hygiene of the appliance. The addition of the notch 103 changes the path of liquid flow, helps to break the surface tension film of breast milk, reduces the resistance of liquid flow, and thus improves the smoothness of milk pouring. The notch 103 can also play a role in allowing outside air to flow back into the milk storage space 101, so that the pressure difference inside and outside the milk storage space 101 reaches balance, and the milk can flow out smoothly under the action of gravity.
[0030] Size difference: The size of the notch 103 in the direction where the edge is located is smaller than the size of the milk pouring port 102 in the same direction. This design is to ensure smooth milk pouring while reducing the possibility of outside pollutants (such as dust and bacteria) entering the milk storage space 101 through the restrictive effect of the notch 103 when not in use, further ensuring the hygienic safety of breast milk.
[0031] In one embodiment, the lateral dimension of the milk pouring port 102 is greater than the lateral dimension of the notch 103.
[0032] In one embodiment, the longitudinal dimension of the milk pouring port 102 is smaller than the longitudinal dimension of the notch 103.
[0033] The lateral dimension of the milk-pouring opening 102 is larger than that of the notch 103. The notch design helps control the flow rate. The longitudinal dimension of the milk-pouring opening is smaller than that of the notch, which helps maintain a certain damping effect while ensuring the smoothness of milk pouring, so as to avoid the out-of-control caused by too fast milk pouring and resulting in milk splashing and pollution.
[0034] Optionally, the edge of the milk-pouring opening 102 includes a straight edge, and the edge of the notch 103 includes a curved edge. The milk-pouring opening 102 has a straight edge, while the edge of the notch 103 is curved. The curved edge of the notch 103 is more likely to break through the liquid surface tension film at the milk-pouring opening during the milk-pouring process, making the milk pouring smoother.
[0035] As Figure 3 shown, in another embodiment, the notch 303 at the edge of the milk-pouring opening 302 may also include a straight edge.
[0036] In some embodiments, the shape of the notch edge may also include both straight and curved edges, and the embodiments of the present application do not limit this.
[0037] Continue to refer to Figure 2 , optionally, the shape of the milk-pouring opening 102 is elongated, and the notch 103 is located at the long-edge of the milk-pouring opening 102. Dust is less likely to enter the milk storage space 101 through the elongated milk-pouring opening 102 to contaminate the milk. However, it is easier to form a liquid surface tension film at the opening of the elongated milk-pouring opening 102, resulting in difficulty in pouring out the milk. Setting the notch 103 at the long-edge of the elongated milk-pouring opening 102 can better solve this problem, forming a pressure difference and breaking through the surface tension film through the notch 103.
[0038] In one embodiment, the notch 103 is located below the milk-pouring opening 102. By setting the notch 103 below the milk-pouring opening 102, under the action of gravity, more milk is concentrated below and breaks through the surface tension film from the notch 103, enabling the milk to flow out smoothly.
[0039] In one embodiment, the breast pump includes a milk bowl 10 and a breast shield 20. The milk bowl 10 and the breast shield 20 enclose to form the milk storage space 101, and the milk-pouring opening 102 and the notch 103 are located on the breast shield 20. In this embodiment, the breast pump uses the milk bowl 10 as the milk storage container. In other embodiments, this structure is not limited. For example, if a milk bottle is used, it must also have a milk-pouring opening with a notch at the milk-pouring opening to enable the milk to flow out smoothly.
[0040] In one embodiment, the milk suction shield 20 is at least partially made of a rigid material, and the milk pouring port 102 and the notch 103 are formed on the part made of the rigid material.
[0041] In some embodiments, the notch 103 is formed at the middle position of the lower edge of the milk pouring port 102.
[0042] The embodiment of the present application further provides a milk suction shield 20, on which a milk pouring port 102 is formed. The milk pouring port 102 is used to communicate the milk storage space 102 of the breast pump with the outside. A notch 103 is formed on the edge 80 of the milk pouring port 102. The notch 103 is communicated with the milk pouring port 102, and the size of the notch 103 in the direction of the edge 80 is smaller than the size of the milk pouring port 102 in the direction of the edge 80.
[0043] In one embodiment, the breast pump includes: a milk storage container 10, a milk suction shield 20, and a main body 30. The milk suction shield 20 is detachably connected to the milk storage container 10, and a milk suction channel 201 is formed inside the milk suction shield 20.
[0044] The main body 30 is detachably connected to the milk storage container 10, and the main body 30 is used to form a negative pressure for milk suction in the milk suction channel 201 to drive the milk in the milk suction channel 201 to flow into the storage space 101.
[0045] In one embodiment, the milk suction shield 20 is at least partially made of a soft material. Specifically, the milk suction shield 20 includes a soft rubber layer 21 made of soft rubber and a hard rubber layer 22 made of hard rubber, wherein the soft rubber layer 21 is on the side close to the human breast. In other embodiments, the milk suction shield 20 can be entirely made of soft rubber or entirely made of hard rubber, and the embodiments of the present application do not limit this. In some embodiments, the nipple channel part 23 of the milk suction shield 20 is entirely made of hard rubber, and the trumpet-shaped breast flange part 24 is a double-layer structure of soft rubber and hard rubber.
[0046] In one embodiment, the main body 30 includes a housing 31 and a negative pressure pump 32, a solenoid valve, a battery 33, a circuit board, etc. located inside the housing 31.
[0047] In one embodiment, a negative pressure chamber 25 is further provided at the end of the nipple channel part 23. The internal space at the end of the nipple channel part 23 is communicated with the negative pressure chamber 25. A diaphragm 26 is arranged in the negative pressure chamber 25. The diaphragm 26 is used for air-liquid isolation between the internal space of the nipple channel part 23 and the main body 30. After the milk suction shield 20 and the milk storage container 10 are assembled, a seal is formed between the negative pressure chamber 25, the diaphragm 26 and the inner wall of the milk storage container 10.
[0048] In one embodiment, a milk outlet is provided at the bottom of the negative pressure chamber 25, and a one-way valve 27 is provided at the milk outlet. The one-way valve 27 is configured to allow the milk sucked from the milk suction channel 203 into the negative pressure chamber 25 to flow unidirectionally into the milk storage space 101. The one-way valve 27 can be a duckbill valve. Of course, in other embodiments, a flap one-way valve can also be used. The embodiments of the present application do not limit this.
[0049] In the embodiment of the present application, a milk storage space is formed inside the breast pump, and a milk pouring port is formed on the breast pump. The milk pouring port is used to communicate the milk storage space with the outside. A notch is formed at the edge of the milk pouring port, and the notch is communicated with the milk pouring port. The size of the notch in the direction of the edge is smaller than the size of the milk pouring port in the direction of the edge. The addition of the notch changes the liquid flow path, helps to break the surface tension film of breast milk, reduces the resistance of liquid flow, and thus improves the smoothness of milk pouring. The notch can also play a role in allowing outside air to flow back into the milk storage space, so that the pressure difference inside and outside the milk storage space reaches balance, and the milk can flow smoothly under the action of gravity.
