[0002] A breast pump, a device specifically designed for extracting and collecting breast milk, mainly comprises three parts: a suction device, a breast shield, and a collection container. The breast shield contains the breast and creates a negative pressure environment inside, thereby enabling effective milk extraction; finally, the extracted milk is collected in the collection container.

[0003] During use, a deformable component that works with the suction device needs to be installed inside. When the suction device generates negative pressure, the deformable component deforms; when the negative pressure disappears, the deformable component returns to its initial state. Currently, this deformable component needs to be installed through the opening of the collection container. During installation, it inevitably comes into contact with the wall of the collection container, which will lead to hygiene problems. In addition, the limited space in the collection container makes it inconvenient to install the deformable component. Utility Model Content

[0041] like Figures 1-3 As shown, Figure 1 A three-dimensional structural diagram of a breast pump; Figure 2 This is a diagram showing the disassembled state of a breast pump; Figure 3 This is a cross-sectional view of a breast pump. The breast pump includes a reservoir 1, a deformable component 2, a suction assembly 3, and a support component 5. The deformable component 2 is disposed on the outer wall of the reservoir 1. The suction assembly 3 and the support component 5 are detachably connected to the reservoir 1. In use, the suction assembly 3 and the deformable component 2 work together to form a negative pressure. The negative pressure causes the deformable component 2 to deform, which in turn generates a negative pressure between the support component 5 and the deformable component 2, thereby realizing the operation of expressing milk from the breast. Finally, the expressed milk is collected by the reservoir 1.

[0042] Please refer to the following: Figure 4 and Figure 5 As shown, Figure 4 This is a three-dimensional structural diagram of the liquid storage component 1; Figure 5This is another three-dimensional structural diagram of the liquid storage component 1. The liquid storage component 1 has a liquid storage tank 11, an inlet 12, a delivery port 13, an outlet 14, and a first negative pressure groove 15. The inlet 12, delivery port 13, and outlet 14 are all connected to the liquid storage tank 11. The breast is placed in the inlet 12 through the support member 5. The obtained milk flows into the liquid storage tank 11 through the delivery port 13 and is finally poured out through the outlet 14. The first negative pressure groove 15 is formed on the outer wall of the liquid storage component 1. In this way, the installation of the deformable part 2 can be completed from the outside of the liquid storage component 1, avoiding the phenomenon that the hand or device comes into contact with the wall of the liquid storage tank 11 when installing the deformable part 2 from the direction of the liquid storage tank 11, thereby improving the hygiene effect when using the breast pump. Furthermore, the outer wall of the liquid storage component 1 is also provided with a receiving groove 16, and the first negative pressure groove 15 is located in the receiving groove 16. Specifically, the inlet 12 and the inlet 13 penetrate through the bottom wall of the receiving groove 16 and communicate with the first negative pressure groove 15. The first negative pressure cavity 4 formed by the suction component 3 and the deformable component 2 is also located in the receiving groove 16. The setting of the receiving groove 16 can make the overall shape of the breast pump more aesthetically pleasing. For example, after the suction component 3 is connected to the liquid storage component 1, its overall cross-section is a semi-circular structure.

[0043] In this embodiment, the deformable part 2 is made of elastic material, the deformable part 2 is snapped into the peripheral wall of the first negative pressure groove 15, and the deformable part 2 can be disassembled.

[0044] Please review Figures 1-3 The suction assembly 3 includes a lower shell 31, an upper shell 32, a suction pump 33, a valve body 34, and a control circuit board 35. The lower shell 31 is disposed on the liquid storage component 1, and the upper shell 32 is disposed on the lower shell 31. The upper shell 32 and the lower shell 31 together form a receiving cavity 7. The suction pump 33, the valve body 34, and the control circuit board 35 are all disposed in the receiving cavity 7, and the suction pump 33 and the valve body 34 are electrically connected to the control circuit board 35. Specifically, the lower shell 31 has a second negative pressure groove 311. The second negative pressure groove 311 and the deformable component 2 together form a first negative pressure cavity 4. The suction pump 33, the valve body 34, and the first negative pressure cavity 4 can form a negative pressure flow channel. The negative pressure flow channel refers to the channel through which the suction pump 33, the valve body 34, and the first negative pressure cavity 4 are connected by a pipe. When the suction pump 33 is working, it draws out the gas in the first negative pressure cavity 4, and the channel through which the gas flows is the negative pressure flow channel. In this embodiment, after the upper shell 32 is assembled, its curvature matches that of the outer surface of the liquid storage component 1, so that the outer surface of the breast pump has a hemispherical structure. The valve body 34 is an existing solenoid valve product, and the negative pressure environment of the first negative pressure chamber 4 can be controlled by setting the valve body 34.

[0045] Furthermore, the suction assembly 3 also includes an operation panel 36, which is connected to the upper shell 32 and protrudes from the surface of the upper shell 32. The operation panel 36 is electrically connected to the control circuit board 35, and the working status, working mode, and working power of the breast pump can be adjusted through the operation panel 36. Of course, information can also be displayed on the operation panel 36.

[0046] In addition, a power module (not shown in the figure) can be set to supply power to the control circuit board 35, and a corresponding charging function can be set to charge the breast pump later.

[0047] Please refer to the following: Figure 6 As shown, Figure 6 This is a three-dimensional structural diagram of the support member 5. The support member 5 has a first support opening 51, which communicates with the insertion opening 12. In use, the breast is placed in the first support opening 51. Specifically, the support member 5 is generally funnel-shaped. Furthermore, the support member 5 also has a slot 52, which is formed around the inner edge of the support member 5. The liquid storage member 1 can be inserted into the slot 52. After the liquid storage member 1 is inserted into the slot 52, the support member 5 and the liquid storage tank 11 of the liquid storage member 1 together form a collection chamber 6. After the milk is squeezed out, it will be transported to the collection chamber 6 for storage, and finally the milk in the collection chamber 6 will be poured out through the outlet 14. It can be understood that although the slot 52 is formed around the breast, in order to facilitate the pouring out of the milk in the collection chamber 6, there is a notch at the position corresponding to the outlet 14, that is, there is a gap between the two ends of the slot 52.

[0048] The breast pump also includes a variable diameter component 8, which is fitted into the first support port 51. The variable diameter component 8 has a second support port 81, which is connected to the insertion port 12. The diameter can be adjusted by the variable diameter component 8, so that the breast pump fits the breast better.

[0049] Please refer to the following: Figure 7 As shown, Figure 7This is a three-dimensional structural diagram of the protective component 9. The breast pump also includes the protective component 9, which covers the side of the support 5 away from the deformable component 2. When the breast pump is not in use, the protective component 9 can be installed on the support 5 to prevent external bacteria and dust from contaminating the inside of the breast pump. Furthermore, the protective component 9 has a support groove 91, which is adapted to the edge of the support 5, that is, the edge of the support 5 can be inserted into the support groove 91 for temporary storage of the breast pump. Even further, the protective component 9 also has a support surface 92, which extends into the support groove 91. The shape of the support surface 92 is adapted to the external shape of the liquid storage component 1. When the support 5 is inserted into the support groove 91, the support surface 92 simultaneously contacts the liquid storage component 1. The arrangement of the support groove 91 and the support surface 92 allows the breast pump to be placed upright on the protective component 9 for easy placement.

[0050] Please review Figure 3 The breast pump also includes a flow-blocking component 10, which is located inside the liquid storage tank 11 and connects the inlet 13 to the liquid storage tank 11. Specifically, the flow-blocking component 10 is an existing one-way valve, such as a duckbill valve, to prevent milk in the liquid storage tank 11 from flowing back through the inlet 13.

[0051] In use, the protective piece 9 is removed from the support piece 5, and the breast enters the first support port 51 or the second support port 81 from direction A. Then, the operation is started through the control panel 36. The control circuit board 35 will make the suction pump 33 and the valve body 34 work, thereby creating a negative pressure in the first negative pressure chamber 4. Under the negative pressure environment, the deformable piece 2 will deform in direction B. At this time, the space between the side of the deformable piece 2 away from the first negative pressure chamber 4 and the breast will also become a negative pressure environment, thereby squeezing the milk out of the breast. Since the flow obstruction piece 10 is in a closed state under the negative pressure environment, the milk cannot flow into the collection chamber 6 temporarily. Then, the control circuit board 35 sends a signal to make the valve body 34 switch modes, allowing external gas to enter and thus destroying the negative pressure environment of the first negative pressure chamber 4. After the negative pressure disappears, the deformable piece 2 will return to its initial position. During this process, the squeezed milk will be forced into the collection chamber 6 through the infusion port 13 and the opened flow obstruction piece 10. The milk will be temporarily stored in the collection chamber 6. By continuously switching the mode of the control valve 34, the above process will be repeated to squeeze out more milk, and finally the milk in the collection chamber 6 will be poured out through the outlet 14.

[0052] In summary, during assembly, the deformable part 2 can be installed on the outside of the liquid storage component 1, thereby avoiding contact with the inner wall of the liquid storage tank 11 and greatly improving hygiene. In addition, since the deformable part 2 is installed on the outside, it has a larger operating space, improving assembly efficiency and convenience.

[0053] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
