Description

Technical Field

[0001] This disclosure relates to the field of maternal and infant products technology, and in particular to a breast pump. Background Technology

[0002] In the field of maternal and infant products, smart breast pumps are an important tool to help breastfeeding women solve the problem of milk collection, and their market demand is growing. With the development of technology, various smart breast pumps are constantly emerging, bringing certain conveniences to breastfeeding women. However, most smart breast pumps on the market currently have relatively limited functions, primarily focusing on the core function of milk expression. In actual use, breastfeeding women often need to perform prolonged expression to meet their milk production needs. However, during extended expression, the continuous negative pressure applied to the breasts by the pump stretches and compresses the breast tissue, easily causing significant pain. This pain not only reduces the comfort of breastfeeding women using the pump but may also lead to resistance to the process, affecting expression efficiency and normal milk production, causing considerable distress for breastfeeding women. Utility Model Content

[0003] In view of this, in order to solve the technical problem in the prior art that the breast tissue is stretched and compressed due to the continuous negative pressure applied to the breast by the breast pump during a long period of breast pumping, which easily leads to obvious pain in women, this disclosure provides a breast pump.

[0004] According to a first aspect of the present disclosure, a breast pump is provided, including a main unit, a breast shield, a massage part, a drive assembly, and a flexible support member. The main unit has a preset mounting position. The breast shield is disposed on one side of the main unit and connected to the main unit. The massage part is disposed on the side of the main unit near the breast shield and electrically connected to the main unit. The drive assembly is disposed on the main unit and electrically connected to the main unit. The drive assembly is configured to generate vibration when energized. The massage part is configured to vibrate synchronously with the vibration of the drive assembly. During vibration, the massage part drives at least a portion of the breast shield to vibrate synchronously. One end of the flexible support member is connected to the inner wall of the preset mounting position, and the other end is connected to the massage part. The flexible support member is sleeved on the outer periphery of the drive assembly. The flexible support member is configured such that the massage part vibrates synchronously under the drive of the drive assembly.

[0005] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: Adding a massage section to the breast pump allows the massage section to vibrate synchronously via the vibration of the drive component, thus enhancing the breast massage function within the intelligent breast pump. By providing moderate massage to the breast during pumping, blood circulation in the breast area can be promoted, breast tissue can be relaxed, and the pulling and compression caused by negative pressure pumping can be reduced, thereby alleviating pain and improving the user experience of the intelligent breast pump. Furthermore, a flexible support is sleeved around the drive component, and the massage section is sleeved around the flexible support. When the drive component vibrates while energized, it simultaneously drives the flexible support and the massage section to vibrate synchronously. The vibration of the massage section can be transmitted to the skin, achieving a moderate massage effect on the breast. Additionally, different massage sections with different functions can be replaced as needed, and they are easy to clean and disinfect individually after disassembly. Standardized interfaces ensure compatibility between different massage sections and the main unit, reducing production and maintenance costs and improving the product's scalability and flexibility.

[0017] Most smart breast pumps on the market currently have relatively limited functions, primarily focusing on the core function of milk expression. In actual use, breastfeeding women often need to perform prolonged expression to meet their milk production needs. However, during extended periods of expression, the continuous negative pressure applied to the breasts by the pump causes stretching and compression of the breast tissue, easily leading to significant pain for women.

[0018] To address the technical problem of significant pain experienced by women during breastfeeding in existing technologies, this disclosure provides a breast pump with a massage unit. The massage unit is driven by a motor within the main unit, and the vibrations of the massage unit are transmitted to the skin through a breast shield to provide a moderate massage to the breasts. In other words, to address the issue of existing breast pumps causing significant pain during breastfeeding, this disclosure integrates a modular massage unit into the breast pump. The massage function is achieved using the main unit's existing drive motor, and the vibrations of the massage unit are transmitted to the skin through the breast shield via a flexible support structure, forming a synergistic "breast pumping + massage" working mode.

[0019] In this disclosure, references Figures 1-5 A breast pump is provided, comprising: a main unit 3, a breast shield 1, a massage part 4, a drive assembly, and a flexible support 6. The main unit 3 has a preset mounting position. The breast shield 1 is disposed on one side of the main unit 3 and connected to the main unit 3. The massage part 4 is disposed on the side of the main unit 3 near the breast shield 1 and is electrically connected to the main unit 3. The drive assembly is disposed on the main unit 3 and is electrically connected to the main unit 3. The drive assembly is configured to generate vibration when energized. The massage part 4 is configured to vibrate synchronously with the vibration of the drive assembly. During the vibration, the massage part 4 drives at least a portion of the breast shield 1 to vibrate synchronously. One end of the flexible support 6 is connected to the inner wall of the preset mounting position, and the other end is connected to the massage part 4. The flexible support 6 is sleeved on the outer periphery of the drive assembly. The flexible support 6 is configured such that the massage part 4 vibrates synchronously under the drive of the drive assembly.

[0020] In this way, after the drive component is powered on and vibrates, the massage part 4 connected to the main unit 3 can vibrate synchronously with it, and drive at least a part of the breast shield 1 to vibrate synchronously. This vibration can provide a gentle massage to the breast and surrounding tissues, promote local blood circulation, and effectively reduce the discomfort caused by tissue traction during breast pumping. At the same time, the flexible support 6, with one end connected to the inner wall of the preset mounting position of the main unit 3 and the other end connected to the massage part 4 and sleeved on the outer periphery of the drive component, provides stable support for the massage part 4, preventing it from shifting or shaking during vibration. It can also maximize the collection of vibration energy generated by the drive component, reduce the dispersion and loss of vibration during transmission, and ensure that the vibration is efficiently transmitted to the massage part 4 and the breast shield 1, further enhancing the targeted and penetrating effect of the massage. In addition, this structure achieves the orderly connection of the drive component, the massage part 4 and the main unit 3 through the flexible support 6, ensuring the reliability of the coordinated work of each component, allowing the massage function to act stably on the breast tissue, and effectively improving the comfort during breast pumping.

[0021] For example, the massage unit 4 shares the same drive component as the main unit 3.

[0022] For example, the massage unit 4 is modularly installed on the main unit 3. In other words, modular installation can be understood as an assembly method in which the massage unit 4 and the main unit 3 are connected by a standardized interface. The interface forms include, but are not limited to, mechanical snap-fit, threaded connection, magnetic attraction, etc., while taking into account the convenience of electrical connection, ensuring that massage units 4 of different specifications are universal.

[0023] Specifically, modular installation can be understood as a standardized, detachable connection structure between the massage unit 4 and the main unit 3. Quick assembly and disassembly are achieved through pre-set matching interfaces. This can be manifested in several ways: for example, the main unit 3 has a mounting base with a snap-fit ​​mechanism, and the massage unit 4 has a corresponding matching slot. During assembly, the massage unit 4 is aligned with the mounting base and pressed down, causing the slot and snap-fit ​​mechanism to engage and secure it. Alternatively, the main unit 3 uses a threaded connector, and the massage unit 4 has matching external threads, allowing for tightening through rotation. Modular installation also includes modular electrical connections. For instance, the mounting base of the main unit 3 has elastic conductive contacts, and the corresponding massage unit 4 has a conductive plate. When the massage unit 4 is mechanically fixed, the conductive plate automatically contacts the conductive contacts, achieving electrical connection with the mainboard control components without additional wiring. This design allows users to replace the massage units 4 with different functions as needed, and facilitates individual cleaning and disinfection after disassembly. The standardized interfaces ensure compatibility between different massage units 4 and the main unit 3, reducing production and maintenance costs and improving product expandability and flexibility.

[0024] For example, the drive assembly includes a drive motor 5, a motor fixing member 9, and a motor fixing cover plate 10, wherein the motor fixing member 9 is disposed on the outer periphery of the drive motor 5, and the motor fixing cover plate 10 is located above the motor fixing member 9.

[0025] Considering the specific installation scheme of the massage part 4 relative to the main unit 3, in the breast pump provided in this embodiment, the massage part 4 is protruding on the side surface of the main unit 3 near the breast shield 1.

[0026] In this way, the massage part 4 protrudes from the surface of the main unit 3 near the breast shield 1, allowing it to be closer to the breast tissue covered by the breast shield 1. Combined with the feature of the drive assembly driving the massage part 4 to vibrate synchronously and causing a portion of the breast shield 1 to vibrate, the protruding structure shortens the transmission path of the massage force. The vibration generated by the motor does not need to be buffered or dispersed by a flat contact surface, and can directly act on the breast and surrounding muscle tissue through the protruding massage part 4. This direct action enhances the targeting and penetration of the massage, more effectively promoting local blood circulation and relaxing tissues tense due to negative pressure breast pumping, thus significantly relieving the pulling pain caused by prolonged breast pumping; that is, achieving pain relief through the massage function.

[0027] Considering one of the positional relationships between the massage part 4, the drive component, and the flexible support 6, in the breast pump provided in this embodiment, there are multiple massage parts 4. Each massage part 4 is provided with a preset mounting position, a drive component, and a flexible support 6. The multiple massage parts 4 are evenly distributed relative to the breast pump 1 in terms of their milk suction positions.

[0028] In this way, each massage unit 4 corresponds to an independent preset mounting position, drive component, and flexible support 6. One end of the flexible support 6 is connected to the inner wall of the preset mounting position, and the other end is connected to the massage unit 4 and sleeved on the outer periphery of the drive component. This structure can create a dedicated and closed vibration transmission path for each massage unit 4, minimizing energy loss during the transmission of vibration from the drive component. At the same time, it avoids vibration interference caused by multiple massage units 4 sharing components, ensuring that each massage unit 4 can vibrate stably and synchronously with its corresponding drive component, guaranteeing the accurate and stable output of massage force. In addition, the multiple massage units 4 are evenly distributed relative to the breast pump 1, allowing the vibration massage effect to evenly cover key areas of the breast that come into contact with the breast pump 1, such as the area around the areola, which is prone to discomfort due to negative pressure. This avoids missing local massage or uneven force, relieving tissue tension and pain during breast pumping from multiple directions. It also adapts to individual differences in breast structure among different people, improving wearing comfort and universality. Furthermore, the independent component configuration reduces the impact of a single component failure on the overall massage function, enhancing the reliability of product operation.

[0029] Considering the second aspect of the positional relationship between the massage part 4, the drive component, and the flexible support 6, there are multiple massage parts 4. Each massage part 4 is provided with a preset installation position, a drive component, and a flexible support 6. The multiple massage parts 4 are distributed in a dispersed manner relative to the milk suction position of the breast shield 1.

[0030] In this way, each massage unit 4 corresponds to an independent preset mounting position, drive component, and flexible support 6. One end of the flexible support 6 is connected to the inner wall of the preset mounting position of the main unit 3, and the other end is connected to the massage unit 4 and sleeved on the outer periphery of the corresponding drive component. This independent configuration creates a dedicated vibration transmission path for each massage unit 4, which can not only avoid the mutual interference of vibration caused by multiple massage units 4 sharing components, but also reduce the energy loss of the drive component vibration during transmission through the structural characteristics of the flexible support 6, ensuring that each massage unit 4 can vibrate stably and synchronously with the corresponding drive component, and ensuring the accurate transmission of massage force. The multiple massage units 4 are distributed in a dispersed manner relative to the breast pumping position of the breast shield 1, so that the vibration massage can cover different areas of the breast related to breast pumping (such as the outer side of the breast, the areola, and other areas that are prone to traction discomfort due to negative pressure breast pumping), achieving targeted relief for multiple areas of the breast, avoiding insufficient local relief caused by single or concentrated massage, further adapting to the individual differences in breast structure of different people, and improving the comfort when wearing and using the product; at the same time, the independent component configuration also reduces the impact of a single component failure on the overall massage function, enhancing the reliability of product operation.

[0031] Considering the specific structural scheme of the flexible support member 6, in the breast pump provided in this embodiment, the flexible support member 6 includes a first elastic support structure 61. The first elastic support structure 61 has an elastic stroke and is used to synchronously follow the movement when the massage part 4 vibrates, so as to transmit the vibration.

[0032] For example, the first elastic support structure 61 has a first bent edge 611.

[0033] For example, the first bent edge 611 can be understood as a bent shape with a certain angle formed at the edge of the first elastic support structure 61. The bent part can not only enhance the overall rigidity of the support structure, but also provide a certain deformation buffer space when vibration is transmitted. Its bending angle can be adapted to the vibration amplitude and transmission requirements of the massage part 4.

[0034] For example, the first elastic support structure 61 can be understood as a ring structure made of elastic material, such as spring steel sheet, elastic plastic, etc. For example, it is a ring-shaped spring sheet arranged around the massage part. Its whole has deformable characteristics, and can bend, stretch and deform when subjected to external force, and return to its original shape after the external force is removed, thereby realizing the effective transmission of vibration.

[0035] For example, the elastic stroke can be understood as the maximum displacement that the first elastic support structure 61 can undergo within the elastic deformation range. This displacement needs to match the vibration amplitude of the massage part 4 to ensure that it can move synchronously with the massage part 4 without losing its support and transmission functions due to excessive deformation.

[0036] In this way, the first bent edge 611 enhances the structural strength and deformation adaptability of the support structure, making the flexible support 6 less prone to damage when following the vibration of the massage part 4; the elastic characteristics of the first elastic support structure 61, combined with its elastic stroke, can achieve flexible following motion when the massage part 4 vibrates, avoiding vibration transmission jamming or energy loss caused by rigid connection, ensuring that vibration can be transmitted efficiently and smoothly from the massage part 4 to the outer cover structure 7 and the breast shield 1; at the same time, the elastic stroke can buffer the impact force during vibration, reduce hard friction and wear between the massage part 4 and the main unit 3 and the breast shield 1, extend the service life of the components, and make the vibration transmission more in line with the force characteristics of the breast skin, improving the comfort and effectiveness of the massage, and further optimizing the user experience of the "breast suction + massage" synergistic mode.

[0037] Considering the scheme that the first elastic support structure 61 and the massage part 4 have synchronous elastic deformation, in the breast pump provided in the embodiments of this disclosure, during the vibration of the massage part 4, the first elastic support structure 61 is configured to have synchronous elastic deformation following the massage part 4, thereby enhancing the stability and comfort of vibration transmission.

[0038] For example, synchronous elastic deformation can be understood as follows: when the massage unit 4 vibrates periodically due to the action of the drive motor 5, such as reciprocating motion along the axial direction, radial oscillation, or combined vibration, the first elastic support structure 61, driven by the massage unit 4, undergoes elastic deformation with the same frequency, approximately the same deformation direction, and a suitable deformation amount. For instance, when the massage unit 4 reciprocates along the axial direction with an amplitude of 0.8 mm, the first bending edge 611 of the first elastic support structure 61 will simultaneously undergo bending deformation, with its extension stroke matching the vibration amplitude of the massage unit 4 (e.g., 0.7-0.9 mm), and the deformation rhythm consistent with the vibration period of the massage unit 4. If the massage unit 4 has a slight radial offset vibration, the annular portion of the first elastic support structure 61 will simultaneously generate radial elastic oscillation, ensuring coordination with the movement state of the massage unit 4. This synchronization is achieved through the rigid connection point (e.g., welding, integral injection molding) between the first elastic support structure 61 and the massage unit 4, and its own elastic characteristics, ensuring that it neither lags behind the vibration of the massage unit 4 nor deviates from synchronization due to excessive deformation.

[0039] In this way, synchronous deformation ensures that the vibration energy of the massage unit 4 can be transmitted to the outer cover structure 7 and the breast shield 1 without delay and with low loss through the first elastic support structure 61, avoiding vibration cancellation or transmission interruption caused by asynchronous movement of the two, greatly enhancing the stability of vibration transmission, and allowing the skin to continuously and evenly feel the massage effect. In addition, the synchronicity of elastic deformation, combined with the buffering effect of the first bent edge 611, can transform the rigid vibration of the massage unit 4 into a softer elastic vibration, reducing the impact on the connection between the main unit 3 and the breast shield 1 during vibration, reducing fatigue damage to components caused by long-term asynchronous vibration, and making the vibration transmitted to the skin more in line with the human body's force habits, avoiding discomfort caused by abrupt vibration, and further improving the comfort and reliability of the "breast suction + massage" synergistic mode.

[0040] Considering the synchronous vibration scheme of the massage part 4 and the first elastic support structure 61, in the breast pump provided in this embodiment, the massage part 4 is connected to at least a portion of the first elastic support structure 61.

[0041] For example, the massage part 4 is connected to at least a portion of the first elastic support structure 61. This can be understood as the massage part 4 and the first elastic support structure 61 not being completely connected as a whole, but rather fixed through specific parts, and the connection area occupies a portion of the total area of ​​the first elastic support structure 61. For instance, if the first elastic support structure 61 is a ring-shaped spring, the massage part 4 can be connected to the inner edge area of ​​the ring-shaped spring by means of a snap or adhesive; if the first elastic support structure 61 is a sheet-like structure, the massage part 4 can be fixed to the central area or one side edge area of ​​the sheet-like structure by screws. This connection method ensures the linkage between the two and also provides sufficient deformation space for the first elastic support structure 61, allowing it to smoothly undergo synchronous elastic deformation when the massage part 4 vibrates.

[0042] In this way, the connection method ensures effective force transmission between the massage unit 4 and the first elastic support structure 61, so that the vibration of the massage unit 4 can directly drive the first elastic support structure 61 to produce synchronous deformation. This avoids the first elastic support structure 61 becoming too rigid and difficult to deform due to an excessively large connection area, or the vibration transmission becoming unstable due to an excessively small connection area. At the same time, the partial connection provides sufficient elastic deformation space for the first elastic support structure 61, enabling it to better follow the vibration rhythm of the massage unit 4, further improving the efficiency and stability of vibration transmission.

[0043] Considering the change of the tensile state of the first elastic support structure 61 during vibration, in the breast pump provided in this embodiment, when the first elastic support structure 61 is in a static state, the structure of the first elastic support structure 61 itself is not in a tensile or compressed state. When the first elastic support structure 61 is in a position far from the static state, the structure of the first elastic support structure 61 is in a stretched state, and the stretched state has the ability to recover the static state.

[0044] In this way, when the first elastic support structure 61 is in a static state, it is not in a stretched or compressed state. This natural structural state can avoid generating additional pre-tightening force on the massage part 4 and the drive component, prevent the parts from deforming or wearing due to continuous stress under static conditions, ensure the positional stability of the initial assembly of the massage part 4 and the drive component, and at the same time reserve sufficient travel space for elastic deformation in the subsequent vibration process, so as to avoid the initial stress limiting the vibration transmission efficiency. When the first elastic support structure 61 is in a state far from the static position, it is in a stretched state and has the ability to return to a static state. The stretched state can accurately adapt to the displacement requirements of the massage part 4 caused by the vibration of the drive component, ensuring that the support component always maintains a stable connection with the preset installation position of the main unit 3 and the massage part 4 during the vibration process, without separation or loosening, and ensuring the continuous transmission of vibration energy from the drive component to the massage part 4. The recoverability allows the support component to reset in time within the vibration cycle, avoiding deformation accumulation that leads to deviation of the vibration trajectory or a decrease in transmission efficiency. At the same time, the stretching deformation buffers the vibration impact, reduces the rigid collision between the massage part 4 and the main unit 3, extends the service life of the components, and allows the vibration of the massage part 4 to maintain regularity, thereby driving the breast shield 1 to achieve stable synchronous vibration, improving the comfort and stability of breast massage.

[0045] Considering the matching installation scheme of the breast pump 1 and the massage part 4, in the breast pump provided in this embodiment, the breast pump 1 includes a cover body and an outer cover structure 7 corresponding to the massage part 4. The cover body fits into the main unit 3, and the outer cover structure 7 covers the side of the massage part 4 away from the drive component. The outer cover structure 7 has an elastic stroke for receiving and transmitting the vibration of the massage part 4 to the skin.

[0046] In this way, the breast shield 1 fits snugly against the main unit 3, ensuring the overall stability of the breast shield 1 assembly and preventing displacement of the breast shield 1 when the massage part 4 vibrates, thus laying a structural foundation for stable vibration transmission. The outer cover structure 7, corresponding to the massage part 4, is positioned on the side of the massage part 4 furthest from the drive component, precisely engaging with the massage part 4 and reducing the dispersion and loss of vibration in the transmission path, ensuring efficient transmission of vibration energy to the outer cover structure 7. Simultaneously, the elastic travel of the outer cover structure 7 not only cushions the rigid impact generated by the vibration of the massage part 4, preventing direct skin contact and discomfort, but also adapts to the contours of the breast skin through its elastic deformation, improving the fit and allowing the vibration to act more evenly and gently on the breast and surrounding tissues. This effectively alleviates tissue tension and pulling sensations caused by negative pressure breast pumping, further optimizing the wearing and massage comfort during the breast pumping process.

[0047] For example, through the connection between the outer garment structure 7 and the flexible support member 6, the vibration effect of the massage part 4 can be transmitted to the breast shield 1, thereby making the position on the breast shield 1 where the massage part 4 is located come into contact with the skin. At this time, the skin can feel the massage effect of the massage part 4.

[0048] For example, the flexible support 6 can be understood as a component disposed around the massage part 4 to enhance the structural stability of the massage part 4 and transmit vibration. Its form is not limited to a specific shape, such as an annular flange, a columnar support, a frame structure with connecting parts, etc. Its core function is to realize vibration transmission and positioning through cooperation with the outer casing structure 7.

[0049] For example, the outer cover structure 7 can be understood as a matching structure on the breast shield 1 corresponding to the flexible support member 6, which can receive and connect the flexible support member 6. For example, it can be a groove, through hole, buckle seat, magnetic suction member, etc., as long as it can achieve detachable or fixed connection with the flexible support member 6 and does not affect the transmission of vibration from the flexible support member 6 to the breast shield 1.

[0050] Considering the specific assembly relationship between the outer sleeve structure 7 and the massage part 4, in the breast pump provided in this embodiment, the outer sleeve structure 7 is fitted onto the outer wall of the corresponding massage part 4, and the outer sleeve structure 7 and the inner wall of the massage part 4 are interference-fitted.

[0051] In this way, the outer sleeve structure 7 is fitted onto the outer wall of the massage part 4 with an interference fit, achieving a tight assembly between the two and completely eliminating assembly gaps. This prevents the dispersion or delay of vibration energy caused by gaps when the massage part 4 vibrates with the drive component, ensuring that the vibration of the massage part 4 can be efficiently and completely transmitted to the outer sleeve structure 7. The outer sleeve structure 7 then precisely acts on the breast skin and surrounding tissues, enhancing the massage's effect on relieving tissue tension caused by negative pressure breast pumping. Simultaneously, the strong connection provided by the interference fit prevents relative displacement or loosening between the outer sleeve structure 7 and the massage part 4 during massage, ensuring synchronized movement of both under continuous vibration. This avoids abnormal noises or localized friction damage caused by loosening, and ensures that the outer sleeve structure 7 always stably conforms to the skin, ensuring uniform vibration transmission and further improving massage comfort and structural reliability during breast pumping.

[0052] For example, the outer cover structure 77 may include a second elastic support structure 71 having a second bent edge 711, the second elastic support structure 71 having an elastic stroke for receiving and transmitting vibrations from the massage part 4 to the skin.

[0053] For example, the second bent edge 711 can be understood as a bent shape formed by the edge of the second elastic support structure 71. This bent shape can enhance the structural strength of the second elastic support structure 71, and at the same time provide a certain buffer when receiving and transmitting vibrations, making the vibration transmission more gentle.

[0054] For example, the second elastic support structure 71 can be understood as a structure made of elastic materials such as silicone or elastic metal sheets, such as an elastic protrusion integrally formed with the breast shield 1, or an elastic ring fixed to the breast shield 1. It can deform when subjected to the vibration force transmitted by the first elastic support structure 61, and return to its original shape after the force disappears, thereby realizing the transmission of vibration.

[0055] For example, the elastic stroke of the second elastic support structure 71 can be understood as the maximum displacement that can be generated within the elastic deformation range. For instance, when receiving vibrations from the massage unit 4, it can generate a telescopic stroke of 0.3-1.5 mm along the vibration direction, or a certain oscillating stroke in the radial direction, which is adapted to the elastic stroke of the first elastic support structure 61 to efficiently receive and transmit vibrations.

[0056] In this way, the second bent edge 711 enhances the rigidity and deformation capacity of the structure, making the second elastic support structure 71 less prone to damage when receiving vibrations, and at the same time, it can better cooperate with the first elastic support structure 61. Its elastic characteristics and elastic stroke can efficiently receive the vibrations transmitted by the first elastic support structure 61 and transmit them smoothly and gently to the breast shield 1, and then from the breast shield 1 to the skin, avoiding energy loss or abrupt impact during vibration transmission. In addition, the structure is adapted to the elastic stroke of the first elastic support structure 61, which can form a good vibration transmission chain, improve the stability and comfort of the massage effect, and further optimize the "breast pumping + massage" synergistic function of the breast pump.

[0057] Considering the specific structural scheme of the flexible support member 6, in the breast pump provided in this embodiment, the flexible support member 6 includes two inverted U-shaped structures, which form a stepped structure. The lower inverted U-shaped structure is located close to the massage part 4. The outer bottom edge of the higher inverted U-shaped structure extends outward to form a retaining edge 611A, which is engaged with the contour edge of the main unit 3 from top to bottom. The cover structure is configured to transmit the vibration to the skin evenly through its own elastic deformation when receiving the vibration of the massage part 4.

[0058] For example, the two inverted U-shaped structures can be understood as follows: each inverted U-shaped structure is formed by a horizontal segment and two vertical segments, forming an overall U-shape with the opening facing upwards. The vertical segment of the lower inverted U-shaped structure is shorter, and its inner side is fixedly connected to the outer wall of the massage part 4 by hot melt adhesive or with a gap fit. The horizontal segment is at a preset distance from the vibration center axis of the massage part 4, closely fitting the outer periphery of the massage part 4. The vertical segment of the higher inverted U-shaped structure is taller than that of the lower one. The horizontal segments of the two inverted U-shaped structures are arranged in parallel, forming a stepped structure with a height difference. The vertical segments of the two structures are connected by an arc transition to avoid stress concentration.

[0059] For example, the edge 611A can be understood as a horizontal edge 611A with a certain width extending outward from the bottom edge of the inverted U-shaped structure at the high position, and the lower surface of the edge 611A is attached to or fitted with the upper surface of the contour edge of the host 3.

[0060] For example, the side of the locking edge 611A away from the inverted U-shaped structure is bent downward to form a folded edge. This folded edge is closely fitted and locked to the inner sidewall of the contour edge of the main body 3, realizing a locking from top to bottom. The fit gap after locking is small.

[0061] For example, the raised edge 711A can be understood as an arc-shaped edge that protrudes upward from the edge of the second elastic support structure 71.

[0062] In this way, the stepped structure enhances the elastic deformation capability of the first elastic support structure 61. The low-position inverted U-shaped structure close to the massage part 4 ensures the stability of the initial vibration transmission, while the high-position inverted U-shaped structure and the locking edge 611A improve the firmness of the connection between the massage part 4 and the main unit 3, preventing loosening during vibration. The raised edge 711A and the locking edge 611A are locked onto the contour edge of the main unit 3, forming a bidirectional limit, so that the first elastic support structure 61 and the second elastic support structure 71 always maintain precise alignment during vibration transmission, reducing vibration loss caused by relative displacement. At the same time, this locking structure can also buffer the impact of vibration on the main unit 3, reduce noise, and the specific shape design of the inverted U-shaped structure and the raised edge 711A makes the elastic deformation conform to the mechanical law, further improving the efficiency and gentleness of vibration transmission, ensuring a stable and comfortable massage effect, and optimizing the overall structural reliability and user experience of the breast pump.

[0063] Considering the scheme that the cover structure receives the vibration of the massage part 4 and then transmits the vibration evenly to the skin through its own elastic deformation, in the breast pump provided in this embodiment, the cover structure is configured to transmit the vibration evenly to the skin through its own elastic deformation when receiving the vibration of the massage part 4.

[0064] For example, the elastic deformation mode of the cover structure: The cover structure is made of silicone material with a certain thickness, and the whole is an arc-shaped sheet that matches the curvature of the outer wall of the breast shield 1. When the massage part 4 receives the vibration transmitted through the first elastic support structure 61, it will reciprocate bending deformation along the vibration direction (such as the axial direction) with the protruding edge 711A as the fulcrum. The bending amplitude changes with the vibration intensity. At the rated vibration frequency, the maximum bending amount is to adapt to the extensibility of the silicone material. The structure itself will produce slight radial expansion and contraction. This multi-directional deformation allows the vibration energy to diffuse to various areas of the structure.

[0065] For example, the uniform transmission of vibration is manifested in the following way: the contact surface between the cover structure and the breast shield 1 adopts a grid-like texture design with a certain size of texture spacing. When the structure deforms, the grid texture can disperse the concentrated vibration energy to the entire contact surface. Tests have shown that at a certain distance from the vibration source (the connection point with the first elastic support structure 61), the difference in vibration amplitude does not exceed a preset range, ensuring that the vibration intensity felt at each point in the skin contact area is basically the same.

[0066] In this way, the shield structure is configured to uniformly transmit vibration through its own elastic deformation, which brings significant technical effects: its multi-directional elastic deformation (bending, radial expansion and contraction) combined with the mesh-like contact surface can transform the concentrated vibration of the massage part 44 into uniformly distributed surface vibration, avoiding skin discomfort caused by excessive local vibration or affecting the massage effect by insufficient local vibration, so that the force on the breast contact area is balanced; this uniform vibration can more effectively relax breast tissue, promote blood circulation, and specifically relieve local pain caused by negative pressure traction during breast pumping, improving the comfort of use; at the same time, the deformation characteristics of silicone material have a buffering effect, which can filter the harsh impact in the vibration, making the vibration transmitted to the skin more gentle, and the stable fit of the structure with the breast shield 11 ensures that the vibration transmission has no dead angles, further enhancing the reliability of the "breast pumping + massage" synergistic function and optimizing the user experience of the product.

[0067] For example, both the first elastic support structure 61 and the cover structure are made of soft rubber.

[0068] In this way, the elastic properties of the soft rubber material itself allow for smoother and more gentle deformation when receiving and transmitting vibrations, reducing vibration jamming and energy loss caused by rigid structures, and ensuring efficient and continuous vibration transmission. The appropriate Shore hardness ensures both the structural support strength and sufficient elastic travel, allowing the first elastic support structure 61 to accurately follow the vibration of the massage part 4, and the cover structure to evenly transmit vibrations to the skin. The medical-grade and food-grade silicone material has good biocompatibility, is safe and harmless when in contact with the skin or near the breast milk area, and is resistant to washing and sterilization, meeting the hygiene requirements of breast pumps. At the same time, the one-piece molding process of the soft rubber structure reduces assembly complexity, improves structural stability and durability, further enhances the reliability and safety of the "breast pumping + massage" system, and optimizes the user experience.

[0069] Considering the layout of the massage section 4 relative to the nipple channel 8, in the breast pump provided in this embodiment, the main unit 3 is provided with a nipple channel 8, and the breast pump also includes a milk storage chamber 2. The nipple channel 8 is used to communicate with the milk storage chamber 2, and the massage head is installed at the contour tangent position A near the nipple channel 8 to adapt to the breast structure of more people.

[0070] For example, the nipple channel 8 is a cylindrical channel that runs through the main unit 3 and the breast shield 1. The vertical deviation between the channel axis and the side of the main unit 3 that is in contact with the skin is small. For example, the vertical deviation does not exceed 0.5mm. Its inner wall is made of smooth food-grade PP material to ensure that the nipple can be inserted smoothly without friction.

[0071] For example, the tangent position A near the nipple channel 8 is a straight line tangent to the cylindrical surface of the nipple channel 8, with the cylindrical surface as the reference. Specifically, if the center of the cross-section of the nipple channel 8 is O and the radius is r, the horizontal distance between the central axis of the massage part 4 and the straight line passing through the center O and perpendicular to the skin surface is r + a preset distance, which is the area near the outer side of the tangent of the nipple channel 8.

[0072] In this way, the layout avoids the central area where the nipple is located, preventing the massage part 4 from directly compressing the nipple and causing discomfort or affecting milk expression. At the same time, it is close to the areola and surrounding tissue of the breast, which can accurately act on the densely distributed area of ​​mammary glands to promote milk secretion and drainage. It can also adapt to the differences in breast size and nipple position of different people. Whether the user has inverted nipples, full breasts or flat breasts, the massage part 4 can effectively contact the breast tissue, which enhances the universality of the product. In addition, this position layout is coordinated with the hard and soft rubber areas of the breast shield 1. With the vibration transmission of the massage part 4, it can more evenly relieve breast pressure during milk expression, further alleviate pain, and improve the overall user experience.

[0073] Consider the heating scheme of the massage section 4 in the breast pump. Multiple massage sections 4 are provided, and at least one massage section 4 is provided with a first heating unit.

[0074] For example, the first heating unit includes a heating resistor with a predetermined area that is electrically connected to the circuit board of the host 3.

[0075] For example, the heating resistor of the preset area can be a heating resistor adapted to the heating area, and the preheating area can be determined according to the actual heating requirements.

[0076] In this way, multiple massage units 4 are provided, enabling wider vibration coverage of the breast and surrounding tissues through multi-area distribution. The drive assembly simultaneously drives the massage units 4 to vibrate and also vibrate the corresponding areas of the breast shield 1, which can more comprehensively promote local blood circulation in the breast and alleviate the discomfort caused by tissue traction during negative pressure breast suction. At least one massage unit 4 is equipped with a first heating unit (including a preset area heating resistor electrically connected to the circuit board of the main unit 3). Relying on a stable circuit connection, it can achieve continuous power supply and heating. The heat is transferred from the massage unit 4 to the breast shield 1 and the skin, further relaxing the breast tissue through the warming effect. This, combined with the vibration massage, creates a synergistic soothing effect. Furthermore, the preset area heating resistor can precisely adapt to the needs of the target heating area, ensuring uniform heat coverage and avoiding localized overheating or insufficient heating. Simultaneously, the configuration of some massage units 4 with heating and others with only vibration can adapt to the different soothing needs of different areas of the breast, improving the product's adaptability to different usage scenarios and users, and ensuring the targeted and practical nature of the massage and heating functions.

[0077] Considering the heat insulation scheme of the massage part 4, in the breast pump provided in this embodiment, there is an insulating heat-conducting layer between the first heating unit and the breast shield 1. The insulating heat-conducting layer is used to conduct the heat generated by the first heating unit to the massage part 4.

[0078] For example, the insulating heat-conducting layer can be a heat-conducting metal structure with a shape adapted to the profile of the heating resistor, and its area can be slightly larger than that of the heating resistor.

[0079] For example, the edges of the insulating heat-conducting layer can be rounded to avoid scratching the bra 1 or the skin.

[0080] For example, one side of the insulating thermally conductive layer is tightly bonded to the heating resistor with high-temperature resistant double-sided adhesive, and the other side is in contact with the outer wall of the breast shield 1. A thin layer of thermally conductive silicone is applied to the contact area to reduce thermal resistance.

[0081] In this way, the pre-set area heating resistor can provide a stable and moderate heat output, meeting the temperature range required for breast heat therapy and avoiding local overheating or insufficient heat. The heat-conducting insulating layer is made of food-grade stainless steel, which can effectively block the electrical connection between the heating resistor and the breast shield 1, ensuring safety, and can also evenly transfer the heat generated by the heating resistor to the breast shield 1, making the overall temperature distribution of the breast shield 1 more uniform. This allows the heat to act gently on the skin, promote blood circulation in the breast, and relieve pain during breast pumping. At the same time, the solid connection between the heating resistor and the circuit board, and the tight fit between the heat-conducting insulating layer and the heating resistor and breast shield 1, ensure the high efficiency and stability of heat transfer. In conjunction with the massage function of the breast pump, this further improves the user's comfort and breast pumping efficiency.

[0082] Considering the synchronous start-up scheme of the massage unit 4 and the breast pump, the vibration start-up and stop states of the massage unit 4 are set synchronously with the pumping state of the breast pump.

[0083] In this way, the vibration on / off state of the massage unit 4 is synchronized with the pumping state of the breast pump, eliminating the need for users to operate the massage and pumping functions separately, greatly simplifying the usage process and improving ease of use. When the breast pump starts pumping, the massage unit 4 starts vibrating simultaneously. The vibration generated by this vibration in a portion of the breast shield 1 acts on the breast and surrounding tissues in real time, promptly promoting local blood circulation and relieving the discomfort caused by tissue traction due to negative pressure during pumping, avoiding initial pumping discomfort caused by delayed massage activation. When pumping stops, the massage unit 4 stops vibrating simultaneously, avoiding energy waste caused by the massage function running idle and preventing unnecessary skin irritation from excessive vibration after pumping. At the same time, this synchronized coordination allows the vibration massage and negative pressure pumping to work synergistically. The relaxing effect of vibration on breast tissue helps milk flow, creating a positive interaction with the pumping function and ensuring a smooth and comfortable pumping process.

[0084] Considering the synchronization scheme between the vibration state of the massage unit 4 and the suction and degassing states of the breast pump, when the breast pump is in the suction state, the drive component drives the massage unit 4 to maintain the vibration state; when the breast pump is in the degassing state, the drive component stops starting.

[0085] In this way, when the breast pump is in suction mode, the drive component drives the massage unit 4 to maintain vibration. At this time, the vibration can work in sync with the negative pressure during suction. The massage unit 4 drives the corresponding area of ​​the breast shield 1 to vibrate, providing a gentle massage to the breast and surrounding tissues. This effectively promotes local blood circulation, relieves the discomfort caused by tissue traction during negative pressure breast pumping, and the gentle force generated by the vibration can also help relax breast tissue, creating more favorable conditions for milk discharge. This works in synergy with the suction function to improve the smoothness of the breast pumping process. When the breast pump is in deflation mode, the drive component stops operating, which avoids unnecessary vibration during the deflation phase (when the negative pressure disappears) from causing unnecessary irritation to the skin, reduces ineffective energy consumption, and prevents additional wear and tear on components such as the massage unit 4 and breast shield 1 caused by vibration during non-pumping phases, thus extending the service life of the components. The overall solution allows the massage function to be precisely matched with the core working rhythm of the breast pump, ensuring both a comfortable experience during breast pumping and the economy and reliability of the equipment operation.

[0086] Considering the synchronization scheme between the vibration frequency of the massage unit 4 and the lactation or suction mode of the breast pump, when the breast pump is in lactation mode, the drive component drives the massage unit 4 to increase the vibration frequency; when the breast pump is in suction mode, the drive component drives the massage unit 4 to decrease the vibration frequency. When the breast pump stops pumping or stops producing milk, the drive unit stops starting.

[0087] In this way, when the breast pump is in lactation mode, the drive component drives the massage unit 4 to increase the vibration frequency. This more powerful vibration stimulates breast tissue, promotes local blood circulation, and clears milk ducts, creating favorable conditions for milk secretion. This meets the need for pre-treatment of the breast in lactation mode to improve lactation efficiency. When the breast pump is in pumping mode, the drive component drives the massage unit 4 to slow down the vibration frequency. This gentle vibration continuously alleviates the discomfort caused by tissue pulling during pumping without interfering with the core function of negative pressure pumping. It avoids overstimulation caused by the superposition of high-frequency vibration and negative pressure, balancing pumping efficiency and user comfort. When the breast pump stops pumping or lactation, the drive component stops operating. This avoids ineffective energy consumption when the function is idle, reduces additional wear and tear on the massage unit 4 and drive component, extends the service life of components, and ensures that the massage function accurately matches the core needs of different working stages of the breast pump. This achieves efficient adaptation of function and scenario, improving the overall user experience and the reliability of the equipment.

[0088] Considering the design where the vibration intensity of the massage unit 4 changes with the milk pumping intensity level, when the milk pumping intensity level increases, the drive component drives the vibration intensity of the massage unit 4 to increase synchronously; when the milk pumping intensity level decreases, the drive component drives the vibration intensity of the massage unit 4 to decrease synchronously.

[0089] In this way, the vibration intensity of the massage unit 4 rises and falls synchronously with the breast pump's suction intensity level, allowing the massage effect to precisely match the pressure state of the breast under different suction intensities: when the suction intensity level increases, the negative pressure and pulling sensation on the breast tissue correspondingly increases. At this time, the drive component drives the massage unit 4 to synchronously increase the vibration intensity, which can promote local blood circulation through more effective vibration and more fully relieve the tissue tension and pulling discomfort caused by increased negative pressure. When the suction intensity level decreases, the negative pressure on the breast weakens, and the vibration intensity decreases synchronously. This avoids unnecessary irritation to the skin from excessive massage while maintaining a moderate soothing effect, preventing an imbalance in comfort caused by a mismatch between vibration intensity and suction intensity. This synchronous adjustment mechanism allows the massage function and the core breast pumping function to work together deeply, always assisting the breast pumping process with an appropriate intensity. This ensures the relief effect under different suction intensities and improves the overall comfort and adaptability of use. At the same time, the stable connection between the drive component and the massage unit 4 ensures the timeliness and stability of the vibration intensity response as the intensity changes with the pump level.

[0090] One possible structural design for a breast pump is to include a milk storage chamber 2, a breast shield 1, a main unit 3, and the milk storage chamber 2, which are stacked sequentially along the thickness of the breast pump.

[0091] In this way, the breast shield 1, the main unit 3, and the milk storage chamber 2 are stacked sequentially along the thickness direction of the breast pump. This arrangement makes full use of the thickness dimension space, significantly compressing the product's lateral volume and forming a compact and orderly overall structure, precisely meeting the core requirements of wearable breast pumps for small size and portability. Simultaneously, the main unit 3, positioned as the intermediate layer between the breast shield 1 and the milk storage chamber 2, shortens the vibration transmission path from the drive component within the main unit 3 to the breast shield 1, reducing energy loss during transmission. This ensures that the vibration generated by the drive component driving the massage part 4 is efficiently transmitted to the breast shield 1, thus stabilizing the breast tissue and alleviating discomfort during pumping. Furthermore, the stacked arrangement of the milk storage chamber 2 adjacent to the main unit 3 ensures smooth communication between the nipple channel 8 on the main unit 3 and the milk storage chamber 2, avoiding leakage or blockage caused by detours in the milk drainage path. This ensures efficient implementation of the core pumping function. In addition, the tight stacking of components along the thickness direction reduces structural wobbling during use, further enhancing stability during wear.

[0092] Considering the second structural design of the breast pump, the breast shield 1 includes a hard plastic area near the center of the main body and a soft plastic area at the edge. The hard plastic area is used to match and engage with the inner circumference of the main body 3 and is connected to the milk storage chamber. The soft plastic area is used to align and install with the side of the main body that is in contact with the skin.

[0093] In this way, the hard rubber area near the center of the breast pump 1 matches and engages with the inner circumference of the main unit 3. Relying on the rigidity of the hard rubber itself, a stable connection between the breast pump 1 and the main unit 3 can be achieved, preventing them from loosening due to vibration or negative pressure of the massage part 4 during breast pumping. At the same time, the design of the hard rubber area connecting with the milk storage cavity ensures the regularity and smoothness of the milk drainage channel, preventing milk leakage due to gaps in the connection or structural deformation, and ensuring the stable implementation of the core breast pumping function. The soft rubber area located on the edge is aligned with the side of the main unit 3 that touches the skin. The flexibility of the soft rubber can precisely adapt to the breast contours of different people, forming a close and soft fit, reducing local pressure on the skin and improving wearing comfort. At the same time, the elasticity of the soft rubber can also compensate for minor errors in the assembly of the breast pump 1 and the main unit 3, further enhancing the fit and sealing, avoiding negative pressure leakage or energy loss during massage vibration transmission. The two work together to ensure the structural stability, functional reliability, and user comfort of the breast pump 1.

[0094] Considering the assembly scheme of the massage unit 4 and the nipple channel 8, the main unit 3 and the breast shield 1 are connected by the nipple channel 8. The massage unit 4 is installed at the contour tangent position A near the nipple channel 8 to accommodate the breast structure of more people.

[0095] In this way, the nipple channel 8 connecting the main unit 3 and the breast shield 1 is the core drainage path for breast pumping. The massage unit 4 is installed close to the tangent of the channel's contour. This avoids the massage unit 4 directly covering or compressing the nipple channel 8 and the nipple area, preventing interference with the core breast pumping function or additional pressure discomfort to the nipple. It also allows the massage unit 4 to precisely target key areas around the areola and breast that are prone to traction discomfort due to negative pressure breast pumping, ensuring that the vibration massage effectively promotes local blood circulation and relieves tissue tension. Simultaneously, this installation position can adapt to individual differences in breast structure among different people (such as breast size, nipple position deviation, etc.). Regardless of whether the nipple position is to the left, right, or in a normal position, the massage unit 4, by being close to the tangent of the nipple channel 8's contour, can form a good fit with the breast tissue, avoiding massage blind spots or poor fit problems caused by differences in breast structure. This significantly improves the product's universality for different users, ensuring that all types of users can obtain a stable massage and soothing effect.
