Description

Technical Field

[0001] This utility model relates to the field of vacuum device technology, and in particular to an integrated valve vacuum pump, a breast pump main unit, and a breast pump. Background Technology

[0002] Existing breast pumps mainly use a vacuum pumping component to extract air, creating a negative pressure air chamber to draw milk out to the milk pumping channel; then, by opening the vent valve, outside air is allowed to enter the air chamber that was originally under negative pressure, restoring the air pressure in the air chamber to atmospheric pressure, while at the same time, the milk in the milk pumping channel is discharged into the milk storage chamber at atmospheric pressure.

[0003] In the aforementioned milk expression process, the vacuum extraction assembly and vent valve of the breast pump are core structural components. However, their current large size restricts the internal structural layout of the breast pump, resulting in a large overall size. Furthermore, both the vacuum extraction assembly and vent valve require electric operation, and the battery size is also limited by the pump's dimensions. The current vacuum extraction assembly and vent valve restrict the size of the breast pump, leading to a poor user experience. Utility Model Content

[0004] The main purpose of this invention is to propose an integrated valve-type vacuum pump, a breast pump main unit, and a breast pump, aiming to solve the problem that the size of the breast pump is limited by the vacuum pumping components and the venting valve.

[0005] To achieve the above objectives, the present invention proposes an integrated valve-type vacuum pump, comprising a suction assembly, a drive motor, a housing, a rotating shaft, a transmission component, and a linkage component. An air chamber is formed within the housing, and the housing has a venting channel and a connection channel communicating with a breast pump. The venting channel connects the air chamber to the outside environment. The drive motor drives the rotating shaft to rotate and causes the suction assembly to extract air from the air chamber. The transmission component is slidably mounted on the rotating shaft, and the linkage component is sleeved on the rotating shaft and can move along the axial direction of the rotating shaft. The drive motor can drive the rotating shaft to rotate and drive the transmission component and the linkage component to seal or open the venting channel.

[0006] In one embodiment, one of the transmission member and the rotating shaft is provided with a limiting groove, and the other of the transmission member and the rotating shaft is provided with a limiting boss that cooperates with the limiting groove. The limiting boss and the limiting groove are rotatable relative to each other.

[0007] In one embodiment, one of the transmission component and the linkage component is provided with a first magnetic component, and the other of the transmission component and the linkage component is provided with a second magnetic component. The first magnetic component and the second magnetic component are magnetically connected. The drive motor drives the rotating shaft to rotate so as to drive the transmission component to move or have a tendency to move along the axial direction of the rotating shaft.

[0008] In one embodiment, there are multiple first magnetic elements or second magnetic elements, with each first magnetic element spaced apart from the linkage element or the transmission element, and each second magnetic element spaced apart from the transmission element or the linkage element.

[0009] In one embodiment, the transmission member is provided with a first boss located at one end of the transmission member near the drive motor, and the linkage member is provided with a second boss. The movement of the transmission member can cause the first boss to abut against the second boss, so that the linkage member moves along the axial direction of the rotating shaft.

[0010] In one embodiment, the integrated valve vacuum pump includes a seal connected to the linkage. The seal is located at one end of the linkage near the venting channel. The drive motor can drive the shaft to rotate to drive the transmission component to slide, and drive the linkage component to slide, so that the seal seals the venting channel.

[0011] In one embodiment, a guide boss is provided inside the housing, and the linkage is formed with a guide groove that mates with the guide boss. Both the guide boss and the guide groove extend along the axial direction of the rotating shaft.

[0012] In one embodiment, the integrated valve vacuum pump further includes a reset elastic element, the two ends of which are elastically connected to the linkage element and the drive motor, respectively, and the reset elastic element is located between the linkage element and the drive motor.

[0013] This utility model also proposes a breast pump main unit, including an integrated valve vacuum pump and a battery that provides power to the integrated valve vacuum pump.

[0014] This utility model also proposes a breast pump, including a breast pump main unit and a suction cup communicating with the air chamber; and a milk storage container, the milk storage container being used to store the milk sucked out by the suction cup.

[0015] This invention presents an integrated valve-type vacuum pump, which integrates the functions of a negative pressure pump and a vent valve through ingenious mechanical design. Specifically, the integrated valve-type vacuum pump includes a suction assembly, a drive motor, a housing, a rotating shaft, a transmission component, and a linkage component. An air chamber is formed within the housing, which has a vent channel and a connection channel communicating with the breast pump. The vent channel connects the air chamber to the outside environment. The drive motor drives the rotating shaft to rotate, thereby activating the suction assembly and creating a negative pressure space within the air chamber. The transmission component slides on the rotating shaft, and the linkage component is fitted onto the rotating shaft and can move axially along the shaft. The drive motor, through the rotation of the rotating shaft, drives the transmission component to slide, thereby controlling the linkage component to seal or open the vent channel, achieving the generation and release of negative pressure. By integrating the suction assembly and the vent valve into a compact housing, additional pipes and components are reduced, effectively decreasing the size of the breast pump. This integrated design allows for more efficient space utilization, making the breast pump more portable. The integrated valve vacuum pump simplifies the control mechanism, allowing users to control both pumping and degassing processes through a single interface, improving ease of use and user experience. The integrated valve design enhances the efficiency of negative pressure formation and degassing, reducing energy loss and making pumping faster while lowering energy consumption. Because pumping and degassing functions are integrated into a single unit, maintenance and component replacement become more centralized and convenient, reducing maintenance costs and complexity. This integrated valve vacuum pump not only solves the problem of excessively large vacuum pumping components and degassing valves in traditional breast pumps but also improves the portability, ease of operation, and efficiency of the breast pump, while reducing maintenance costs and providing users with a superior user experience.

[0028] This utility model proposes an integrated valve vacuum pump 100.

[0029] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the integrated valve vacuum pump 100 includes an air extraction assembly 1, a drive motor 2, a housing 3, a rotating shaft 4, a transmission component 5, and a linkage component 6. An air chamber 3a is formed inside the housing 3. The housing 3 has an air venting channel 3b and a connecting channel 3c that communicates with a breast pump. The air venting channel 3b connects the air chamber 3a to the outside. The drive motor 2 drives the rotating shaft 4 to rotate and drives the air extraction assembly 1 to extract the air from the air chamber 3a. The transmission component 5 is slidably disposed on the rotating shaft 4, and the linkage component 6 is sleeved on the rotating shaft 4 and can move along the axial direction of the rotating shaft 4. The drive motor 2 can drive the rotating shaft 4 to rotate and drive the transmission component 5 and the linkage component 6 to seal or open the air venting channel 3b.

[0030] In one embodiment, the housing 3 has an internal air chamber 3a, and the housing 3 has a venting channel 3b and a connecting channel 3c that communicates with the breast pump. The venting channel 3b connects the air chamber 3a to the external environment, while the connecting channel 3c connects the air chamber 3a to the milk-suction part of the breast pump. The drive motor 2 is connected to the suction assembly 1 via a rotating shaft 4. When the drive motor 2 operates, it drives the rotating shaft 4 to rotate, thereby driving the suction assembly 1 to work, drawing air out of the air chamber 3a to the outside, creating a negative pressure space within the air chamber 3a, thus achieving the milk-suction function. By integrating the venting channel 3b and the connecting channel 3c inside the housing 3, the number of external pipes and connecting components is reduced, making the entire vacuum pump structure more compact and easier to integrate into the breast pump main unit. The integrated valve vacuum pump 100 simplifies the operation of the breast pump; users only need to operate the integrated valve vacuum pump 100 to control the milk-suction and venting processes, improving ease of use. By precisely controlling the opening and closing of the venting channel 3b, the negative pressure inside the air chamber 3a can be precisely controlled, thereby adapting to the milk pumping needs of different users and improving milk pumping efficiency.

[0031] It should be noted that the transmission component 5 is designed as a slider, which is fixed to the rotating shaft 4 by a guide rail or bearing, allowing it to slide along the shaft 4. The linkage component 6 is designed as a part with a seal 63, which is fitted onto the rotating shaft 4 and its axial movement along the rotating shaft 4 is controlled by the movement of the slider. The drive motor 2 drives the rotating shaft 4 to rotate via gears, belts, or a direct connection. The rotation of the rotating shaft 4 causes the slider to slide, which in turn pushes the seal valve to move on the rotating shaft 4, thus sealing or opening the venting channel 3b. Through the design of the transmission component 5 and the linkage component 6, precise control of the opening and closing of the venting channel 3b can be achieved, thereby accurately adjusting the negative pressure to meet the milk pumping needs of different users. This design optimizes the internal structure of the breast pump, reduces additional parts and connections, making the breast pump more compact, portable, and easy to use. Due to the direct connection between the transmission component 5 and the linkage component 6, the opening and closing response of the venting channel 3b is faster, improving the working efficiency of the breast pump. By reducing the number of moving parts and optimizing the structural design, the durability and reliability of the entire vacuum pump are improved, extending the product's service life.

[0032] This utility model presents an integrated valve-type vacuum pump 100, which integrates the functions of a negative pressure pump and a vent valve through ingenious mechanical design. Specifically, the integrated valve-type vacuum pump 100 includes a suction assembly 1, a drive motor 2, a housing 3, a rotating shaft 4, a transmission component 5, and a linkage component 6. An air chamber 3a is formed within the housing 3. The housing 3 has a vent channel 3b and a connecting channel 3c that communicates with a breast pump. The vent channel 3b connects the air chamber 3a to the outside environment. The drive motor 2 drives the rotating shaft 4 to rotate, thereby causing the suction assembly 1 to operate and creating a negative pressure space within the air chamber 3a. The transmission component 5 slides on the rotating shaft 4, and the linkage component 6 is fitted onto the rotating shaft 4 and can move axially along the rotating shaft 4. The drive motor 2 drives the transmission component 5 to slide through the rotation of the rotating shaft 4, thereby controlling the linkage component 6 to seal or open the vent channel 3b, realizing the generation and release of negative pressure. By integrating the vacuum pump assembly 1 and the vent valve into a compact housing 3, the size of the breast pump is effectively reduced by eliminating additional piping and components. This integrated design allows for more efficient space utilization, making the breast pump more portable. The integrated valve vacuum pump 100 simplifies the control mechanism, allowing users to control the pumping and venting processes through a single operating interface, improving ease of use and user experience. The integrated valve vacuum pump 100 design improves the efficiency of negative pressure formation and venting, reduces energy loss, makes the pumping process faster, and lowers energy consumption. Since the pumping and venting functions are integrated into one unit, maintenance and component replacement become more centralized and convenient, reducing maintenance costs and complexity. This integrated valve vacuum pump 100 not only solves the problem of excessively large vacuum pump assembly 1 and vent valve in traditional breast pumps, but also improves the portability, ease of operation, and efficiency of the breast pump, while reducing maintenance costs and providing users with a superior user experience.

[0033] In one embodiment of this utility model, please refer to Figure 3 One of the transmission component 5 and the rotating shaft 4 is provided with a limiting groove 5a, and the other of the transmission component 5 and the rotating shaft 4 is provided with a limiting boss 41 that cooperates with the limiting groove 5a. The limiting boss 41 and the limiting groove 5a can rotate relative to each other.

[0034] In this embodiment, one of the transmission component 5 and the rotating shaft 4 is provided with a limiting groove 5a, and the other of the transmission component 5 and the rotating shaft 4 is provided with a limiting boss 41 that cooperates with the limiting groove 5a. The transmission component 5 and the rotating shaft 4 achieve mutual rotation through the cooperation of the limiting boss 41 and the limiting groove 5a, and the transmission component 5 achieves axial movement during rotation. Specifically, both the limiting groove 5a and the limiting boss 41 are designed with a helical shape. Through the cooperation of the limiting boss 41 and the limiting groove 5a, precise limiting can be achieved, while the structure is simple and easy to manufacture and maintain. The simplified structure reduces material and manufacturing costs, making the entire device more economical and practical. The design of the limiting structure allows operators to easily achieve limiting control of rotating parts, improving the convenience of operation. The limiting structure can prevent excessive rotation or displacement of rotating parts, thereby improving the safety and reliability of mechanical equipment.

[0035] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 One of the transmission component 5 and the linkage component 6 is provided with a first magnetic component 51, and the other of the transmission component 5 and the linkage component 6 is provided with a second magnetic component 61. The first magnetic component 51 and the second magnetic component 61 are magnetically connected. The drive motor 2 drives the rotating shaft 4 to rotate so as to drive the transmission component 5 to move or have a tendency to move along the axial direction of the rotating shaft 4.

[0036] In one embodiment, the transmission component 5 and the linkage component 6 are magnetically connected via a first magnetic component 51 and a second magnetic component 61. Specifically, the transmission component 5 can be designed as a permanent magnet, while the linkage component 6 is designed as a component made of ferromagnetic material. Thus, the first magnetic component 51 (transmission component 5) and the second magnetic component 61 (linkage component 6) can be connected by magnetic force. The drive motor 2 drives the rotating shaft 4 to rotate. Due to the magnetic connection between the transmission component 5 and the linkage component 6, the magnetic transmission component 5 moves along the axial direction of the rotating shaft 4 or has a tendency to move along the axial direction of the rotating shaft 4, thereby driving the linkage component 6 to move along the axial direction of the rotating shaft 4 to seal or expose the vent hole. In another embodiment, the transmission component 5 can be designed as an iron block, while the linkage component 6 is designed as a permanent magnet, and the two are connected via a first magnetic component 51 and a second magnetic component 61. Since there is no contact between the driving component and the driven component, there is no rigid connection problem, thus avoiding the transmission of vibration or sudden changes and achieving smooth operation of the working machinery.

[0037] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 There are multiple first magnetic elements 51 or second magnetic elements 61, with each first magnetic element 51 spaced apart from the linkage element 6 or the transmission element 5, and each second magnetic element 61 spaced apart from the transmission element 5 or the linkage element 6.

[0038] In this embodiment, the transmission component 5 and the linkage component 6 are magnetically connected through multiple magnetic components spaced apart. Specifically, the transmission component 5 and the linkage component 6 can each be provided with multiple first magnetic components 51 and multiple second magnetic components 61, which are arranged at intervals along the radial direction. During the rotation of the transmission component 5, the connection between the magnetic units is more stable under the attraction between the multiple first magnetic components 51 and the second magnetic components 61, while maintaining effective transmission of magnetic force. At the same time, since the multiple first magnetic components 51 and the multiple second magnetic components 61 increase the weight of the transmission component 5 and the linkage component 6, the centrifugal force on the transmission component 5 and the linkage component 6 is increased, further improving the motion efficiency of the transmission component 5 and the linkage component 6. By spaced out the multiple magnetic components, the magnetic field distribution can be optimized, and the torque transmission efficiency can be improved, especially in the gap-distributed and combined pull-push designs. The spaced out arrangement of multiple magnetic components can reduce the risk of motion failure between the transmission component 5 and the linkage component 6 due to overload of a single magnetic component, thereby improving the stability and reliability of the entire system. By rationally designing the spacing of magnetic components, short circuits or interactions between like magnetic fields can be reduced, thereby lowering the risk of demagnetization. The non-contact connection of the magnetic components also reduces mechanical wear, lowering maintenance costs and complexity.

[0039] In one embodiment of this utility model, please refer to Figure 4 The transmission component 5 is provided with a first boss 52, which is located at one end of the transmission component 5 near the drive motor 2. The linkage component 6 is provided with a second boss 62. The movement of the transmission component 5 can drive the first boss 52 to abut against the second boss 62, so that the linkage component 6 can move along the axial direction of the rotating shaft 4.

[0040] In one embodiment, the transmission component 5 is designed with a first boss 52 located at the end of the transmission component 5 near the drive motor 2. The linkage component 6 is designed with a second boss 62. When the drive motor 2 drives the rotating shaft 4 to rotate, the transmission component 5 moves accordingly, and the first boss 52 on it abuts against the second boss 62 on the linkage component 6. This causes the linkage component 6 to move along the axial direction of the rotating shaft 4, thereby sealing the vent hole. The first boss 52 and the second boss 62 can be protrusions surrounding the transmission component 5 and the linkage component 6, or they can be multi-segment structures surrounding the transmission component 5 and the linkage component 6. Through the direct abutment of the first boss 52 and the second boss 62, direct drive from the transmission component 5 to the linkage component 6 can be achieved, reducing energy loss and transmission delay. The boss design in this technical solution is simple, easy to manufacture and integrate into existing mechanical systems, reducing overall complexity and cost. Due to its simple structure, the boss design facilitates inspection and maintenance, helping to reduce maintenance workload and costs during long-term operation.

[0041] In one embodiment of this utility model, please refer to Figure 3 and Figure 5 The integrated valve vacuum pump 100 includes a seal 63, which is connected to the linkage 6. The seal 63 is located at one end of the linkage 6 near the venting channel 3b. The drive motor 2 can drive the rotating shaft 4 to rotate, thereby driving the transmission 5 to slide and the linkage 6 to slide, so that the seal 63 seals the venting channel 3b.

[0042] In this embodiment, the integrated valve vacuum pump 100 integrates a seal 63, which is connected to the linkage 6 via bolts or clips and is located at the end of the linkage 6 near the venting channel 3b. When the drive motor 2 starts and drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the transmission component 5 to move axially along the rotating shaft 4, which in turn drives the linkage 6 to slide axially along the rotating shaft 4. The movement of the linkage 6 causes the seal 63 to move to the position of the venting channel 3b, thereby achieving the sealing or opening of the venting channel 3b by the seal 63.

[0043] In this embodiment, the transmission component 5 can be a slider that slides on the rotating shaft 4 and is connected to the linkage component 6 via a linkage mechanism. When the rotating shaft 4 rotates, the slider moves, pushing the linkage component 6 to move axially along the rotating shaft 4 via the linkage, so that the seal 63 can reach the venting channel 3b and seal it.

[0044] In another embodiment, the transmission component 5 can be a screw, while the linkage component 6 is designed as a nut that meshes with the screw. When the drive motor 2 drives the screw to rotate, the nut (i.e., the linkage component 6) moves axially along the screw. Since the seal 63 is fixed to the nut, the seal 63 also moves accordingly to achieve a seal on the venting passage 3b.

[0045] By precisely controlling the movement of the transmission component 5 and the linkage component 6, the sealing component 63 can accurately seal the venting channel 3b, preventing gas leakage. This technical solution simplifies the sealing operation of the venting channel 3b; simply starting the drive motor 2 is sufficient to move and seal the sealing component 63, making the operation simple and quick. Since the drive motor 2 directly drives the rotating shaft 4, a rapid response is achieved, quickly sealing the venting channel 3b and improving system efficiency. In this technical solution, the transmission component 5 and the linkage component 6 have simple structures, low maintenance and replacement costs, and help reduce long-term operating costs.

[0046] In one embodiment of this utility model, please refer to Figures 1 to 3 The housing 3 has a protruding guide boss 31, and the linkage 6 has a guide groove 6a that cooperates with the guide boss 31. Both the guide boss 31 and the guide groove 6a extend along the axial direction of the rotating shaft 4.

[0047] In one embodiment, the housing 3 has one or more guide bosses 31 inside, which protrude along the axial direction of the rotating shaft 4. The linkage 6 has guide grooves 6a that match the shape and size of the guide bosses 31, also extending along the axial direction of the rotating shaft 4. This design allows the linkage 6 to move smoothly along the axial direction of the rotating shaft 4 under the guidance of the guide bosses 31, ensuring precise and controlled movement of the linkage 6. In this embodiment, the guide bosses 31 can be designed as cylindrical, and the guide grooves 6a on the linkage 6 can be designed as corresponding cylindrical grooves. This design allows the linkage 6 to slide axially while rotating around the guide bosses 31, achieving precise guidance and movement. In another embodiment, the guide bosses 31 can be designed as inclined surfaces with a specific angle, and the guide grooves 6a on the linkage 6 can be designed as corresponding inclined grooves. This design allows the linkage 6 to achieve axial acceleration or deceleration movement when subjected to driving force, through the cooperation of the inclined guide bosses 31 and the inclined guide grooves 6a. The cooperation between the guide boss 31 and the guide groove 6a provides precise guidance, ensuring that the linkage 6 moves along a predetermined path, thus improving the accuracy and reliability of the entire system. A well-designed guide reduces friction on the linkage 6 during movement, lowers energy consumption, and extends component lifespan. The internal guide boss 31 and the guide groove 6a on the linkage 6 simplify the mechanical structure, reduce additional guiding components, and make the design more compact. The design of the guide boss 31 and guide groove 6a improves the stability of the linkage 6's movement, reduces deviations caused by vibration or impact, and is suitable for applications requiring high-precision control.

[0048] In one embodiment of this utility model, please refer to Figures 1 to 3 The integrated valve vacuum pump 100 also includes a reset elastic element 7. The two ends of the reset elastic element 7 are elastically connected to the linkage element 6 and the drive motor 2, respectively. The reset elastic element 7 is located between the linkage element 6 and the drive motor 2.

[0049] In this embodiment, the reset elastic element 7 is designed to ensure that the linkage 6 can return to its initial position after operation. Specifically, one end of the reset elastic element 7 is connected to the linkage 6, and the other end is connected to the drive motor 2, located between the linkage 6 and the drive motor 2. This design ensures that when the drive motor 2 drives the rotating shaft 4 to rotate and moves the transmission component 5, the linkage 6 also moves accordingly. After completing its function, the elastic force of the reset elastic element 7 acts on the linkage 6, causing it to return to its initial position.

[0050] In this embodiment, the reset elastic element 7 can be a spring, with one end fixed to the linkage 6 and the other end fixed to the housing of the drive motor 2. After the transmission element 5 completes its action of pushing the linkage 6, the restoring force of the spring pulls the linkage 6 back to its initial position, ensuring that the seal 63 can accurately reset to seal the venting channel 3b. In another embodiment, the reset elastic element 7 can be a rubber bellows, which is elastic and can withstand a certain amount of tension and compression. One end of the bellows is connected to the linkage 6, and the other end is connected to the fixed part of the drive motor 2. When the transmission element 5 moves the linkage 6, the bellows is stretched; after the action is completed, the bellows naturally returns to its original shape, pushing the linkage 6 back to its initial position, thereby realizing the reset of the seal 63.

[0051] The design of the reset elastic element 7 ensures that the linkage 6 can accurately return to its initial position after operation, which is crucial for maintaining normal equipment operation and preventing gas leakage. The automatic reset function of the reset elastic element 7 improves the reliability of linkage 6 operation and reduces the risk of equipment failure due to improper manual reset. The automatic reset mechanism reduces the need for continuous monitoring and adjustment of the linkage 6 position, thereby reducing maintenance workload and costs. The use of the reset elastic element 7 reduces wear on linkage 6 and seal 63, extending the service life of components.

[0052] This utility model also proposes a breast pump main unit, which includes an integrated valve vacuum pump 100 and a battery that provides power to the integrated valve vacuum pump 100. The specific structure of the integrated valve vacuum pump 100 is as described in the above embodiments. Since this breast pump main unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0053] This utility model also proposes a breast pump, including a breast pump main unit and a suction cup connected to an air chamber 3a; and a milk storage container for storing milk sucked out by the suction cup.

[0054] In this embodiment, the breast pump main unit integrates an integrated valve-type vacuum pump 100 and a battery that provides power to the pump. The design of the breast pump main unit allows the integrated valve-type vacuum pump 100 to work seamlessly with the battery, achieving portable and efficient breast pumping functionality. The integrated valve-type vacuum pump 100 includes components such as a transmission component 5, a linkage component 6, a guide boss 31, a guide groove 6a, and a reset elastic component 7, ensuring the compactness of the breast pump main unit and ease of operation. The breast pump main unit is connected to the battery via a cable, and the battery provides the necessary power for the vacuum pump's operation. Due to the design of the integrated valve-type vacuum pump 100 and the portable battery, the breast pump main unit is lighter and easier to carry and use, especially suitable for use when out and about. The efficient sealing and venting mechanism of the integrated valve-type vacuum pump 100 ensures the efficiency of the breast pumping process and reduces the time required for pumping.

[0055] The core components of the breast pump proposed in this invention include a breast pump main unit, a suction cup communicating with an air chamber 3a, and a milk storage container. The breast pump main unit integrates the aforementioned integrated valve-type vacuum pump 100, which is responsible for generating and maintaining the negative pressure required for milk extraction. The suction cup is designed to conform to the mother's breast and is connected to the air chamber 3a of the breast pump main unit to extract milk. The milk storage container is used to collect and store the milk extracted from the suction cup. The suction cup can be designed as a cup-shaped structure made of silicone material, with a soft edge on the inside to ensure a tight seal and comfortable fit against the breast. The suction cup is connected to the breast pump main unit via a flexible tube that can withstand negative pressure and is easy to bend and manipulate to adapt to different usage environments. The high efficiency of the integrated valve-type vacuum pump 100 ensures that the breast pump can quickly generate negative pressure, thereby efficiently extracting milk.
