Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and in particular to a breast pump. Background Technology

[0002] A breast pump is an aid specifically designed for breastfeeding mothers. Its main function is to help them express breast milk from their breasts. Breast pumps can safely express and store breast milk, making it convenient for mothers to provide breast milk for their babies when they are away at work, traveling, or in other situations where direct breastfeeding is not possible. Breast pumps can also help relieve blocked milk ducts. Blocked milk ducts are a common problem for breastfeeding mothers, and if not treated promptly, can lead to more serious health problems such as mastitis. Regular use of a breast pump can effectively unclog milk ducts, reduce the risk of mastitis, and protect the breast health of breastfeeding mothers.

[0003] Existing breast pumps often include massage or heating functions to enhance mothers' comfort. However, the heating element in some devices is complexly designed, requiring separate cables or additional interfaces to connect the heating element to the control circuit. This not only increases structural complexity but also poses risks such as unstable connections, wear, and electrical leakage during the assembly and disassembly of the breast shield, affecting the product's stability and safety. Furthermore, some solutions use simple patch-type heating, lacking good structural integration and failing to achieve rapid assembly and automatic docking. Therefore, there is an urgent need for a more structurally sound, more stable, and easily assembled / disassembled heating breast pump to improve ease of use and safety. Utility Model Content

[0010] In one embodiment, at least one of the connecting portion or the mating portion is a retractable locking structure. When the breast suction shield is assembled with the main unit housing, the locking structure locks the breast suction shield and the main unit housing while the connecting portion and the mating portion are electrically connected.

[0011] In one embodiment, both the connecting part and the mating part are made of metal.

[0012] In one embodiment, the breast shield includes a first body and a second body connected to each other, the first body and the second body enclosing a receiving cavity; the therapeutic component is located within the receiving cavity.

[0013] In one embodiment, the first body is located at the end of the second body away from the host; the second body has a connection hole that connects the receiving cavity to the outside, and the physiotherapy component is at least partially exposed in the connection hole.

[0015] In one embodiment, the host has a mounting slot, the second body is accommodated within the mounting slot, and the first body is at least partially accommodated within the mounting slot.

[0016] In one embodiment, the main unit has a massage part at one end near the breast shield, and the massage part is electrically connected to the main unit; when the main unit is working, the massage part can massage the breasts of the breastfeeding mother.

[0017] In one embodiment, at least a portion of the breast shield is integrally molded from soft and hard plastic, with the soft plastic portion designed to flexibly conform to the breast and the hard plastic portion providing structural support and enhancing connection stability.

[0018] The technical solution provided by this utility model integrates the heating element into the breast pump shield and electrically connects it to the circuit module in the main unit, thereby improving the heating efficiency and overall compactness. The breast pump shield and the main unit shell are detachably connected, and the heating element and the circuit module are automatically connected through an electrical connection component, reducing manual operation and improving user experience. The electrical connection component may include an elastic structure, a snap-fit ​​structure, or a locking structure, which can achieve stable contact, electrical connection, and mechanical limiting during assembly, effectively preventing electrical faults or poor contact caused by loosening.

[0033] This utility model proposes a breast pump 100.

[0034] Please see Figures 1 to 3 In one embodiment of the present invention, the breast pump 100 includes a main unit 1, a breast shield 2, a milk storage container 3, and a therapeutic component 4. The main unit 1 has a circuit module 11 for power supply. The therapeutic component 4 is disposed on the breast shield 2 and is electrically connected to the circuit module 11 of the main unit 1 to realize the power supply control of the therapeutic component 4.

[0035] In this embodiment, the breast pump 100 includes a main unit 1, a breast shield 2, a milk storage container 3, and a therapeutic component 4. The main unit 1 has a built-in circuit module 11, which provides power support and a control system for the entire breast pump 100. The therapeutic component 4 is mounted on the breast shield 2, for example, using an electric heating film or heating wire as the heating element, and is connected to the circuit module 11 of the main unit 1 via a flexible conductive wire or a built-in conductive rail. To ensure the stability and safety of the connection, an elastic, magnetic connection interface or a snap-fit ​​connection structure can be used, so that when the breast shield 2 is installed on the main unit 1, the therapeutic component 4 can automatically achieve electrical connection with the circuit module 11. When the breast shield 2 is connected to the main unit 1 via magnetic attraction, the built-in conductive contacts can accurately align, ensuring stable current transmission, thereby realizing power control of the therapeutic component 4 and providing the user with a comfortable hot compress or massage experience. In addition, a sealing ring can be provided at the connection part 41 between the breast shield 2 and the main unit 1 to prevent liquid from seeping into the circuit, further improving the safety of the product.

[0036] This invention relates to a breast pump 100, which significantly improves ease of use and safety by integrating the electrical connection between the therapeutic component 4 and the circuit module 11 of the main unit 1. The magnetic or snap-on connection structure makes the installation and removal of the breast shield 2 simpler and faster, eliminating user concerns about plugging and unplugging the connection cable and greatly improving efficiency. The built-in conductive rail or flexible conductive wire design avoids the structural complexity and wear risks associated with traditional connection wires, effectively reducing the risk of leakage and ensuring user health and safety. Precise power control of the therapeutic component 4 via the circuit module 11 allows for precise adjustment of the heat therapy temperature to meet the needs of different users. For example, users can select different heat therapy temperatures and massage modes according to their own needs, enhancing the user experience. This design not only optimizes the functionality of the breast pump 100 but also improves the overall performance and market competitiveness of the product.

[0037] In one embodiment of this utility model, please refer to Figures 1 to 3 The main unit 1 includes a main unit housing 12, the breast suction shield 2 is detachably assembled and connected to the main unit housing 12, and the physiotherapy component 4 is electrically connected to the circuit module 11 of the main unit 1 through an electrical connection component.

[0038] In one embodiment, the main unit housing 12 is designed to facilitate the installation and removal of the breast pump shield 2. The breast pump shield 2 is detachably connected to the main unit housing 12 via threaded engagement, snap-fit, or magnetic connection. For example, the top of the main unit housing 12 has internal threads or slots, and the bottom of the breast pump shield 2 has corresponding external threads or snaps, allowing installation to be completed by screwing or pressing. The therapeutic component 4 (such as an electric heating film, electric heating wire, or vibration massage element) is installed on the inner or outer side of the breast pump shield 2 and connected to the circuit module 11 of the main unit 1 via an electrical connection assembly. The electrical connection assembly can be a flexible conductive wire, conductive contacts, or a wireless sensing module. Taking conductive contacts as an example, the inner side of the main unit housing 12 has female contacts, and the bottom of the breast pump shield 2 has male contacts. When the breast pump shield 2 is installed in place, the male and female contacts automatically align to achieve electrical connection. This design ensures a stable connection and reliable power transmission between the breast pump shield 2 and the main unit 1, while also facilitating user replacement or cleaning of the breast pump shield 2 as needed.

[0039] The breast pump 100 of this invention significantly improves the ease of use and safety of the product through the detachable assembly connection between the main unit housing 12 and the breast shield 2, as well as the design of the electrical connection components. The detachable assembly method makes the installation and removal of the breast shield 2 simpler and faster, allowing users to easily replace or clean the shield and maintain hygiene. The stable connection between the therapeutic component 4 and the circuit module 11 of the main unit 1 is achieved through electrical connection components (such as conductive contacts or flexible conductive wires), avoiding the complexity and wear risks associated with traditional connection wires and reducing the risk of leakage.

[0040] In one embodiment of this utility model, please refer to Figure 1 The electrical connection assembly includes a connecting part 41 of the physiotherapy component 4 and a mating part 111 of the circuit module 11. When the breast suction shield 2 is assembled and connected to the main unit housing 12, the connecting part 41 and the mating part 111 contact and are electrically connected.

[0041] In this embodiment, the design of the electrical connection components ensures a stable electrical connection between the therapeutic device 4 and the circuit module 11 of the main unit 1. Specifically, the connecting part 41 of the therapeutic device 4 can be designed as a protruding metal conductive contact or a flexible conductive sheet, while the mating part 111 of the circuit module 11 is a corresponding recessed metal contact groove or conductive socket. When the breast suction shield 2 is assembled and connected to the main unit housing 12, the connecting part 41 of the therapeutic device 4 and the mating part 111 of the circuit module 11 achieve electrical connection through physical contact. For example, the bottom of the breast suction shield 2 is provided with multiple circular metal conductive contacts (connecting parts 41), and the corresponding position of the main unit housing 12 is provided with a matching circular groove (matting part 111), with a conductive spring sheet embedded in the groove. When the breast suction shield 2 is installed in place, the conductive contacts and the conductive spring sheet are in close contact, forming a stable electrical connection, thereby supplying power to the therapeutic device 4. In addition, a magnetic conductive connection method can also be adopted, that is, magnetic materials are provided in the connecting part 41 and the mating part 111, and the electrical connection is achieved by magnetic attraction, further improving the stability and reliability of the connection.

[0042] This invention achieves automatic electrical connection between the breast pump shield 2 and the main unit 1 by designing the connecting part 41 of the therapeutic component 4 and the mating part 111 of the circuit module 11, significantly improving the product's ease of use and safety. This contact-type electrical connection eliminates the need for complex wiring or plugging / unplugging operations; the user automatically completes the electrical connection when installing the breast pump shield 2, greatly simplifying the usage process. The combination of metal conductive contacts and conductive spring sheets, or a magnetic connection method, ensures a tight and stable connection, avoiding leakage or functional failure due to poor contact or loosening. The design of the conductive spring sheets effectively compensates for minor unevenness of the contact surface, ensuring good electrical contact.

[0043] In one embodiment of this utility model, please refer to Figure 1 One of the connecting part 41 and the mating part 111 is a retractable elastic structure. When the breast suction shield 2 is assembled and connected with the main unit housing 12, the elastic structure makes the connecting part 41 and the mating part 111 tightly connected.

[0044] In one embodiment, to ensure a tight connection between the connecting portion 41 of the therapeutic component 4 and the mating portion 111 of the circuit module 11 of the main unit 1, one part is designed as a stretchable elastic structure. For example, the mating portion 111 can be designed as a groove with an elastic conductive spring sheet, while the connecting portion 41 is a metal conductive contact fixed to the breast shield 2. When the breast shield 2 is assembled with the main unit housing 12, the elastic conductive spring sheet will elastically deform due to contact pressure, thereby tightly fitting the metal conductive contact of the connecting portion 41. This elastic structure can effectively compensate for minor errors in the assembly process, ensuring the stability and reliability of the connection. By introducing a stretchable elastic structure into the electrical connection assembly, the connection stability and safety of the breast pump 100 are significantly improved. The design of the elastic structure can effectively compensate for minor errors in the assembly process, ensuring that the connecting portion 41 and the mating portion 111 maintain tight contact under various assembly conditions, avoiding failure of the heat therapy or massage function due to poor contact. For example, the use of an elastic conductive spring sheet can automatically adapt to different contact pressures, ensuring a stable electrical connection while reducing wear caused by frequent disassembly and assembly.

[0045] In one embodiment of this utility model, please refer to Figure 1 and Figure 5 The connecting part 41 and the mating part 111 each include a locking recess and a locking protrusion. When the breast suction shield 2 is assembled and connected to the main unit housing 12, the locking recess and the locking protrusion engage.

[0046] In this embodiment, to achieve a secure assembly connection between the breast pump shield 2 and the main unit housing 12, the connecting portion 41 and the mating portion 111 of the electrical connection assembly adopt a snap-fit ​​structure design. Specifically, the connecting portion 41 can be designed as a protruding snap-fit ​​convex part, such as a circular or rectangular conductive metal protrusion; while the mating portion 111 is designed as a matching snap-fit ​​recess, such as a corresponding circular or rectangular conductive groove. When the breast pump shield 2 is assembled with the main unit housing 12, the snap-fit ​​convex part inserts into the snap-fit ​​recess, achieving a tight fit through shape matching. The snap-fit ​​convex part of the connecting portion 41 can be designed with a structure with elastic barbs, while the snap-fit ​​recess of the mating portion 111 is designed with a structure with corresponding slots, so that during assembly, the elastic barbs can engage with the slots to achieve a secure connection. This snap-fit ​​structure not only ensures the stability of the electrical connection but also enhances the mechanical connection strength between the breast pump shield 2 and the main unit housing 12.

[0047] This invention significantly improves the assembly stability and electrical connection reliability of the breast pump 100 by employing a snap-fit ​​structure design at the connecting part 41 and the mating part 111. The mating structure of the snap-fit ​​recess and snap-fit ​​protrusion ensures that the breast shield 2 and the main unit housing 12 are quickly and accurately connected during assembly, avoiding poor electrical connection due to loosening or detachment. For example, the mating of the snap-fit ​​protrusion with elastic barbs and the slot-type snap-fit ​​recess not only achieves a stable mechanical connection but also ensures good electrical conductivity through close contact. This design also simplifies the user's operation steps, making the installation and removal of the breast shield 2 more convenient. At the same time, the snap-fit ​​structure effectively prevents the breast shield 2 from accidentally loosening due to external forces during use, improving product safety and user experience.

[0048] In one embodiment of this utility model, please refer to Figure 1 At least one of the connecting part 41 or the mating part 111 is a retractable locking structure. When the breast pump shield 2 is assembled and connected to the main unit housing 12, the locking structure locks the breast pump shield 2 and the main unit housing 12 while the connecting part 41 and the mating part 111 are electrically connected.

[0049] In one embodiment, at least one of the connecting part 41 or the mating part 111 is designed as a retractable locking structure to achieve a secure connection between the breast pump shield 2 and the main unit housing 12. For example, the connecting part 41 can be designed as a conductive contact with an elastic telescopic function, and it has a spring device inside to realize telescopic movement. The mating part 111 is a conductive groove fixed on the main unit housing 12, and the groove has a locking hole that matches the elastic telescopic contact. When the breast pump shield 2 and the main unit housing 12 are assembled and connected, the elastic telescopic contact is inserted into the conductive groove and locked into the locking hole under the action of the spring, thereby realizing electrical connection and locking the breast pump shield 2 and the main unit housing 12. By setting a retractable locking structure in the connecting part 41 or the mating part 111, the connection stability and safety of the breast pump 100 are significantly improved. The retractable locking structure can achieve quick and reliable locking when the breast pump shield 2 and the main unit housing 12 are assembled, ensuring that the two will not loosen or fall off during use.

[0050] In one embodiment of this utility model, please refer to Figure 1 Both the connecting part 41 and the mating part 111 are made of metal.

[0051] In this embodiment, both the connecting part 41 and the mating part 111 are made of metal to ensure good electrical conductivity and structural strength. For example, the connecting part 41 can be designed as a metal conductive post fixed to the breast suction shield 2, and its material can be a copper alloy or aluminum alloy with excellent conductivity. The surface is tin-plated or silver-plated to improve oxidation resistance and conductivity. The mating part 111 is a metal conductive socket provided on the main unit housing 12, also made of copper alloy or aluminum alloy, and has an elastic metal sheet on its inner side to enhance contact stability. When the breast suction shield 2 is assembled and connected to the main unit housing 12, the metal conductive post is inserted into the metal conductive socket, and the excellent conductivity of the metal material achieves a stable circuit connection. In addition, to further enhance the reliability of the connection, tiny protrusions and grooves can be provided on the contact surface of the metal conductive post and the socket to improve the quality of electrical connection by increasing the contact area and pressure.

[0052] In one embodiment of this utility model, please refer to Figure 1 The breast shield 2 includes a first body 21 and a second body 22 that are connected to each other. The first body 21 and the second body 22 enclose a receiving cavity 2a; the physiotherapy component 4 is located within the receiving cavity 2a.

[0053] In one embodiment, the breast shield 2 consists of a first body 21 and a second body 22, which are connected to each other by means of threaded connection, snap-fit ​​connection, or welding, and together enclose a receiving cavity 2a. For example, the first body 21 can be designed as a cylindrical shell with threads or grooves on its inner side; the second body 22 is a matching cylindrical liner with corresponding threads or snaps on its outer side. During assembly, the second body 22 is screwed or snapped into the first body 21 to form a sealed receiving cavity 2a. The therapeutic component 4 (such as an electric heating film, a vibration massage element, etc.) is designed with a structure that matches the shape of the receiving cavity 2a, such as a circular or elliptical sheet, and is fixed in the receiving cavity 2a by snaps, adhesives, or embedded structures. For example, an annular groove can be provided on the inner wall of the receiving cavity 2a, and the edge of the therapeutic component 4 has a matching snap edge, which limits the therapeutic component 4 in the receiving cavity 2a by snapping, ensuring its stable installation and use inside the breast shield 2. By designing the breast shield 2 as a structure composed of a first body 21 and a second body 22, and forming a receiving cavity 2a therein to confine the therapeutic component 4, the structural stability and functional integration of the product are significantly improved. The split-type design of the breast shield 2 facilitates manufacturing and assembly, reducing production costs. The receiving cavity 2a provides a stable installation space for the therapeutic component 4, ensuring that it will not shift or loosen during use, thereby improving the reliability of the heat therapy or massage function.

[0054] In one embodiment of this utility model, please refer to Figures 4 to 6The first body 21 is located at the end of the second body 22 away from the host 1; the second body 22 has a connection hole 22a, which connects the receiving cavity 2a to the outside, and the physiotherapy component 4 is at least partially exposed in the connection hole 22a.

[0055] In this embodiment, the first body 21 of the breast suction shield 2 is located at the end of the second body 22 away from the main unit 1, forming a split structure. A connection hole 22a is provided on the portion of the second body 22 near the main unit housing 12, directly connecting the receiving cavity 2a to the outside. The therapeutic element 4 (such as an electric heating film or massage element) is partially or entirely installed within the receiving cavity 2a, and partially exposed to the outside of the breast suction shield 2 through the connection hole 22a. For example, the therapeutic element 4 can be designed as a circular thin sheet with conductive contacts, its edge fixed within the receiving cavity 2a, while the conductive contacts are exposed through the connection hole 22a for electrical connection to the circuit module 11 of the main unit 1. The shape and size of the connection hole 22a can be adjusted according to the design of the therapeutic element 4, for example, designed as circular, square, or polygonal, to ensure that the conductive contacts of the therapeutic element 4 can stably contact the mating part 111 of the main unit 1. By creating a connection hole 22a on the second body 22 and exposing the therapeutic component 4 within it, an efficient electrical connection is achieved between the breast suction shield 2 and the main unit 1 circuit module 11, while maintaining the product's compact structure and airtightness. The design of the connection hole 22a not only provides a channel for the conductive contacts of the therapeutic component 4 to contact the main unit 1 circuit module 11, but also reduces the use of additional connecting wires or interfaces, lowering structural complexity and potential failure risks. Exposing the conductive contacts directly through the connection hole 22a avoids leakage or poor contact problems caused by worn connecting wires or loose interfaces. This design also facilitates cleaning and maintenance of the breast suction shield 2, as the presence of the connection hole 22a makes the installation and removal of the therapeutic component 4 more convenient.

[0056] In one embodiment of this utility model, please refer to Figure 3 and Figure 7 The main unit 1 is equipped with a negative pressure component 13, the second body 22 has a negative pressure chamber 22b, a milk suction channel 2b is formed inside the breast suction shield 2, the negative pressure chamber 22b is connected to the milk suction channel 2b, and the negative pressure component 13 is movably disposed in the negative pressure chamber 22b; the main unit 1 can drive the negative pressure component 13 to move so that negative pressure is generated in the negative pressure chamber 22b and the milk suction channel 2b.

[0057] In one embodiment, the main unit 1 is equipped with a negative pressure component 13, such as a piston-type or diaphragm-type negative pressure pump. The second body 22 has a negative pressure chamber 22b inside, which is connected to the milk suction channel 2b inside the breast pump shield 2 through one or more connecting holes. The negative pressure component 13 is movably disposed within the negative pressure chamber 22b via a drive mechanism of the main unit 1 (such as a motor-driven crank-connecting rod mechanism or gear transmission mechanism). For example, the negative pressure component 13 can be a reciprocating piston, with one end connected to the drive motor of the main unit 1 and the other end located within the negative pressure chamber 22b. When the main unit 1 is started, the drive motor drives the piston to reciprocate within the negative pressure chamber 22b via a transmission mechanism, thereby generating negative pressure within the negative pressure chamber 22b and the milk suction channel 2b. The milk suction channel 2b of the breast pump shield 2 is designed in a funnel or cylindrical shape, with its open end contacting the breast and the other end connected to the negative pressure chamber 22b through a connecting hole, ensuring that negative pressure can be effectively transmitted into the milk suction channel 2b to achieve milk extraction. Furthermore, a one-way valve can be installed between the negative pressure chamber 22b and the milk suction channel 2b to prevent milk from flowing back into the negative pressure chamber 22b. By installing the negative pressure component 13 in the main unit 1 and connecting the negative pressure chamber 22b with the milk suction channel 2b inside the breast shield 2, a highly efficient and stable milk extraction function is achieved. The movable design of the negative pressure component 13 allows the main unit 1 to precisely control the intensity and frequency of the negative pressure, thereby adapting to the breastfeeding needs of different users. For example, by adjusting the motor speed and piston stroke, multiple milk suction modes, from gentle to strong, can be achieved to meet the usage needs of breastfeeding mothers in different scenarios.

[0058] In one embodiment of this utility model, please refer to Figures 1 to 3 The host 1 has a mounting slot 1a, the second body 22 is accommodated in the mounting slot 1a, and the first body 21 is at least partially accommodated in the mounting slot 1a.

[0059] In this embodiment, the main unit housing 12 is designed with a mounting groove 1a for accommodating and fixing the second body 22 and part of the first body 21 of the breast pump shield 2. The shape of the mounting groove 1a matches the shape of the breast pump shield 2 to ensure a tight fit between the two. For example, the mounting groove 1a can be designed as a cylindrical or flared groove with a snap or threaded structure on its inner wall. The outer side of the second body 22 is correspondingly designed with a slot or thread, and the second body 22 is fixed in the mounting groove 1a by snap engagement or thread engagement. A part of the first body 21 (such as the end near the second body 22) is also designed to be accommodated in the mounting groove 1a, and the entire breast pump shield 2 is securely installed through the connection structure (such as threads or snaps) with the second body 22. For example, the end of the first body 21 can be designed as an annular protrusion that engages with the annular slot in the mounting groove 1a to further enhance the stability of the installation. This design not only ensures a tight connection between the breast pump shield 2 and the main unit 1, but also facilitates disassembly and cleaning by the user.

[0060] In one embodiment of this utility model, please refer to Figure 1 The main unit 1 has a massage part 14 at one end near the breast shield 2, and the massage part 14 is electrically connected to the main unit 1; when the main unit 1 is working, the massage part 14 can massage the breasts of the breastfeeding mother.

[0061] In one embodiment, a massage part 14 is provided at the end of the main unit 1 near the breast shield 2. The massage part 14 is electrically connected to the control module of the main unit 1 via a built-in circuit. The massage part 14 can take various specific forms, such as a vibrating massage element, a rotating massage head, or a pneumatic massage device. Taking a vibrating massage element as an example, it can be a miniature vibration motor installed at the end of the main unit 1, powered by the power supply and control module of the main unit 1, which controls the vibration frequency and intensity. The surface of the massage part 14 is designed as a soft silicone layer that contacts the breast to improve comfort during use. When the main unit 1 is working, the control module drives the vibration motor to run, generating vibrations that are transmitted to the breast through the silicone layer, thereby achieving the massage function. In addition, the massage part 14 can also be designed as a rotating massage head with multiple massage bumps, driven by a motor to rotate and provide a comprehensive massage to the breast. The shape and size of the massage part 14 can be optimized according to ergonomic principles to better fit the shape of the breast and ensure the massage effect. This design not only improves the comfort of using the breast pump 100 but also effectively promotes milk secretion and relieves breast engorgement and blocked milk ducts. For example, the vibrating massage element stimulates the milk ducts in the breast through vibration, helping milk to flow more smoothly and reducing discomfort for breastfeeding mothers. The rotating massage head further promotes blood circulation in the breast through all-around massage movements, preventing mastitis. In addition, the soft silicone layer design of the massage section 14 improves comfort when in contact with the breast, reduces friction and pressure, and enhances the user experience. This multi-functional integrated design makes the breast pump 100 not just a simple milk extraction tool, but also a comprehensive breastfeeding aid that provides all-around care.

[0062] In one embodiment of this utility model, please refer to Figure 6 and Figure 7 At least a portion of the breast shield 2 is integrally molded from soft and hard plastic. The soft plastic portion is used to flexibly conform to the breast, while the hard plastic portion provides structural support and enhances connection stability.

[0063] In this embodiment, the breast shield 2 is manufactured using a one-piece molding process combining soft and hard plastics to optimize both function and structure. Specifically, the breast shield 2 consists of a soft plastic part and a hard plastic part. The soft plastic part is typically located on the inner side of the breast shield 2, directly contacting the breast, and is made of soft silicone or thermoplastic elastomer (TPE) material, providing good flexibility and fit to ensure comfort during use. The hard plastic part is located on the outer side of the breast shield 2 or in key structural areas, and is made of rigid plastic materials such as polypropylene (PP) or polycarbonate (PC), providing necessary structural support and strength for the breast shield 2, while enhancing the connection stability with the main unit 1. For example, the inner edge and bottom of the breast shield 2 can be designed as soft plastic parts to achieve a flexible fit to the breast, while the outer connecting part 41 and the main structure are made of hard plastic parts to ensure that the breast shield 2 will not deform or loosen during use. This one-piece design, combining soft and hard plastic, is achieved through a dual-injection molding process. First, the hard plastic portion is injection molded, then the soft plastic portion is injection molded onto its surface, forming a unified structure. The soft plastic portion's flexible fit against the breast effectively reduces discomfort during breastfeeding, providing a more natural and comfortable experience, especially suitable for the sensitive breast tissue of breastfeeding mothers. Simultaneously, the hard plastic portion provides sufficient structural support for the breast shield 2, ensuring it doesn't deform under negative pressure and extending the product's lifespan. Furthermore, the hard plastic portion enhances the connection stability between the breast shield 2 and the main unit 1, reducing the risk of loosening or detachment due to external forces and improving the overall reliability of the product. This design not only optimizes the function and performance of the breast shield 2 but also enhances the product's aesthetics and user experience, making it more suitable for the daily needs of breastfeeding mothers.
