Description

Technical Field

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

[0002] Traditional breast pumps are designed to rely on a continuous negative pressure mode to pump milk from a woman's breasts. This method typically involves applying uniform and continuous negative pressure to the breasts within a set working cycle. However, this traditional operating mode of breast pumps has some significant limitations and problems.

[0003] First, the continuous negative pressure of traditional breast pumps does not effectively simulate the natural sucking rhythm and fluctuations of an infant during breastfeeding. During natural breastfeeding, the infant stimulates the mother's breasts with different sucking intensities and frequencies. This stimulation helps to trigger the "let-out" reflex, which is the phenomenon of milk ejection produced when the mammary glands receive appropriate stimulation. This process involves the secretion of oxytocin from the pituitary gland, which is a key hormone that promotes milk secretion.

[0004] However, traditional breast pumps, due to their single suction mode, often cannot mimic this natural rhythm and depth, resulting in deficiencies in milk extraction efficiency and breast health. Women using traditional breast pumps may experience insufficient milk extraction or breast pain after pumping. Continuous inappropriate suction may also lead to blocked milk ducts and even cause health problems such as mastitis.

[0005] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0006] The aforementioned technical problem with traditional breast pumps is that they continuously generate negative pressure to suction milk from the breast within a set working cycle, which cannot achieve the "milk release" reflex produced by the action of an infant "latching" the woman's breast and sucking.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A breast pump that mimics infant sucking includes a milk bowl, a breast pump main unit connected to the milk bowl, and a breast shield structure. The breast shield structure has a breast cover, and the breast cover has an elastic sucking-simulating inner airbag assembly. The breast pump main unit includes an air source device that communicates with the elastic sucking-simulating inner airbag assembly. When the air source device inflates or deflates the elastic sucking-simulating inner airbag assembly, the elastic sucking-simulating inner airbag assembly can deform to achieve deformation expansion or deformation contraction.

[0009] As described above, in a baby-sucking-inspired breast pump, the elastic sucking-inspired inner liner airbag assembly includes an upper inner liner lip and a lower inner liner lip.

[0010] As described above, the simulated baby sucking breast pump includes an elastic simulated sucking liner airbag assembly that further comprises a left liner lip and a right liner lip, wherein the upper liner lip, left liner lip, lower liner lip, and right liner lip sequentially surround each other to form a ring-shaped simulated sucking liner.

[0011] As described above, in a baby-sucking breast pump, the elastic sucking-inspired liner airbag assembly further includes a liner seat connected to the sucking-inspired liner, the liner seat being detachably connected to the bra structure.

[0012] As described above, in a breast pump that mimics infant sucking, the elastic, sucking-inspired inner liner airbag assembly and the breast shield are integrally molded.

[0013] As described above, in a baby-sucking-inspired breast pump, the elastic sucking-inspired inner liner airbag assembly includes a breast massage section and a nipple massage section, the bra structure includes a milk suction channel, and the nipple massage section is located between the breast massage section and the milk suction channel, and is connected to both respectively.

[0014] As described above, in a baby-like breast pump, the breast massage section and the nipple massage section are connected, and the internal space of the breast massage section gradually narrows along the nipple massage section toward the outlet of the breast shield.

[0015] As described above, a breast pump that mimics a baby's sucking motion includes a sealed housing as the main unit, an air source device with an air intake end and an air intake pipe, a negative pressure chamber in the milk bowl, a breast shield structure with a milk suction channel located in the negative pressure chamber, and an air suction channel between the sealed housing and the negative pressure chamber that connects the air intake pipe to the negative pressure chamber.

[0016] As described above, in a baby-sucking breast pump, the air source device includes an integrated pump and valve air pump.

[0017] As described above, in a baby-like breast pump, the air source device is provided with an air delivery end, the air delivery end is provided with an air delivery pipe communicating with the air delivery channel, and the air delivery pipe is provided with a heating module capable of heating the gas delivered by the air delivery pipe.

[0018] The beneficial effects of this utility model are:

[0019] This utility model relates to a breast pump that mimics infant sucking, and relates to the field of breast pump technology. It includes a milk bowl, a breast pump main unit connected to the milk bowl, and a bra structure. The bra structure includes a breast shield with an elastic, simulated-sucking inner airbag assembly. The breast pump main unit includes an air source device connected to the elastic, simulated-sucking inner airbag assembly. When the air source device inflates or deflates the elastic, simulated-sucking inner airbag assembly, the assembly deforms to expand or contract, producing an effect similar to infant sucking. This simulated infant sucking action effectively stimulates the mother's mammary glands and promotes oxytocin secretion. This design, by simulating the natural breastfeeding process, helps trigger the "milk release" reflex, causing milk to spray out after appropriate stimulation of the mammary glands.

[0037] Example 1:

[0038] like Figures 1 to 8As shown, this embodiment of a breast pump that mimics infant sucking includes a milk bowl 1, a breast pump main unit 2 connected to the milk bowl 1, and a breast shield structure 3. The breast shield structure 3 has a breast shield 31, and the breast shield 31 has an elastic mimicking sucking inner airbag assembly 4. The breast pump main unit 2 includes an air source device 22 connected to the elastic mimicking sucking inner airbag assembly 4. When the air source device 22 inflates or deflates the elastic mimicking sucking inner airbag assembly 4, the elastic mimicking sucking inner airbag assembly 4 can deform to expand or contract, producing an effect similar to infant sucking. The mimicking infant sucking action can effectively stimulate the mother's mammary glands and promote the secretion of oxytocin. This design, by simulating the natural breastfeeding process, helps to trigger the "milk release" reflex, causing the mammary glands to produce milk ejection after receiving appropriate stimulation. Compared with the single negative pressure mode of traditional breast pumps, this biomimetic design is more conducive to improving lactation efficiency.

[0039] like Figures 1 to 8 As shown, the elastic suction-simulating inner liner airbag assembly 4 of this embodiment includes an upper inner liner lip 41 and a lower inner liner lip 42.

[0040] Specifically, by setting an elastic, sucking-simulating inner lining airbag assembly at the bra, which includes an upper lining lip and a lower lining lip, when the air source device inflates or deflates the airbag assembly through the air delivery channel, the upper and lower lining lips will deform and expand or deform and contract, producing an effect similar to a baby sucking.

[0041] Furthermore, by controlling the inflation and deflation process of the air source device, the suction strength and frequency can be adjusted. This adjustability allows the breast pump to be customized according to the mother's individual needs and comfort, providing a more personalized breast pumping solution.

[0042] Furthermore, the elastic inner liner airbag assembly provides a softer, more conforming contact surface, reducing stimulation and discomfort to the breasts during pumping. The deformation of the upper and lower lips of the liner can better adapt to the shape of the breast, providing a more comfortable pumping experience.

[0043] like Figures 1 to 8 As shown, the elastic simulated sucking liner airbag assembly 4 of this embodiment also includes a left liner 43 and a right liner 44. The upper liner 41, the left liner 43, the lower liner 42 and the right liner 44 are arranged in sequence to form a ring-shaped simulated sucking liner 45.

[0044] Specifically, by introducing a left lip liner and a right lip liner, the simulated sucking liner airbag assembly can more comprehensively and three-dimensionally simulate the movements of an infant's mouth during the sucking process. The coordinated movement of the four simulated lip liner airbags can produce a more realistic infant sucking effect, which is closer to the natural breastfeeding process.

[0045] Preferably, the deformation and compression of the four inner lining lip airbags on the top, bottom, left, and right sides can stimulate the breast from different directions, more effectively promoting milk release. This multi-directional stimulation mode helps improve milk expression efficiency, promotes the secretion of more milk, and allows mothers to complete the milk expression process in a shorter time.

[0046] Preferably, the coordinated movement of the four lips can provide a more even and gentle suction distribution. Compared with a single upper and lower lip design, the introduction of left and right lips can reduce local pressure concentration and make the suction more dispersed and balanced. This helps to reduce discomfort to the breasts during breastfeeding and improve the mother's comfort.

[0047] Furthermore, the deformable shape of the four lips on the inner lining allows it to better adapt to the different breast shapes and sizes of mothers. This adaptive design ensures that the breast pump can fit the breast better, thereby improving milk expression efficiency and reducing leakage problems.

[0048] Preferably, the rhythm changes of an infant's sucking can be further simulated by controlling the order and timing of inflation and deflation of the four lips. This simulation of rhythm helps stimulate the mother's mammary glands, promotes the secretion of oxytocin, and thus increases milk production.

[0049] In other embodiments, the elastic, sucking-like inner liner airbag assembly 4 includes an upper inner liner 41 and a lower inner liner 42, but does not include a left inner liner 43 and a right inner liner 44. A suitable design can be selected according to actual needs.

[0050] Preferably, in this embodiment, the simulated sucking liner 45 is ring-shaped. The ring-shaped simulated sucking liner 45 can more evenly cover the milk-suction area of ​​the breast, achieving all-round stimulation. This design simulates the natural envelopment of an infant when sucking milk, which can effectively stimulate the mammary glands and thus improve lactation efficiency.

[0051] Furthermore, the ring design helps to create a better seal, reduce air leakage, and ensure effective transmission of suction. This sealing effect makes the breast pump more efficient while reducing milk spillage and waste.

[0052] Furthermore, the soft and elastic material of the ring-shaped sucking liner can provide a similar feel to a baby's mouth, giving mothers a more natural breastfeeding experience. This design may help reduce the psychological stress on mothers, making the breastfeeding process more relaxed and natural.

[0053] Due to its elasticity and shape, the ring-shaped lining can better adapt to breasts of different shapes and sizes, which improves its versatility and comfort.

[0054] In other embodiments, the upper lip 41, left lip 43, lower lip 42, and right lip 44 of the inner lining are arranged in sequence around the gap to form a sucking-simulating inner lining 45. The design of the gaps between the multiple lips allows each lip to move independently, providing a more flexible and diverse stimulation pattern. This design can simulate the tongue and mouth movements of an infant during sucking, thereby providing a more realistic and effective stimulation.

[0055] Furthermore, the gaps between the lip air sacs can serve as channels for milk flow, allowing milk to flow more smoothly from the breast to the collector. This design helps reduce milk stasis and lowers the risk of problems such as mastitis.

[0056] Furthermore, the interval design allows the breast pump to target specific areas of the breast, which is very helpful in resolving localized milk duct blockages or promoting milk release from specific areas.

[0057] like Figures 1 to 8 As shown, in this embodiment, the elastic suction-simulating lining airbag assembly 4 and the breast bra 31 are integrally molded structures. Preferably, the suction-simulating lining 45 and the breast bra structure 3 are integrally molded structures.

[0058] Preferably, the one-piece molded structure eliminates the connecting parts between the sucking liner 45 and the breast shield 31 or the breast shield structure 3, simplifying the overall structure of the breast pump. This not only reduces production costs but also improves the reliability of the breast pump and reduces problems such as air leakage or detachment caused by poor component connections.

[0059] Furthermore, the one-piece molding design avoids any gaps that may exist between the simulated sucking liner 45 and the breast bra 31 or bra structure 3, thus providing better sealing performance. This not only improves milk expression efficiency but also prevents milk leakage, ensuring the hygiene and safety of the milk expression process.

[0060] Furthermore, the seamless integration of the sucking-in liner 45 with the breast shield 31 or bra structure 3 provides a smoother and more continuous contact surface, reducing stimulation and discomfort to the breast. This design allows mothers to feel more comfortable during breastfeeding and reduces the pressure and discomfort that may be caused by the edges of the breast pump.

[0061] Furthermore, in this embodiment, the simulated sucking liner 45 and the bra structure 3 are integrally formed, and there is an air bladder space between the inner wall of the simulated sucking liner 45 and the side wall of the bra 31. The air source device 22 is connected to the air bladder space through the air supply channel 5. By controlling the air source device 22 to supply air to the air bladder space, the simulated sucking liner 45 can produce periodic deformation, simulating the sucking action of an infant. This deformation can produce a massage and stimulation effect on the breast, promote the secretion and discharge of milk, and improve the milk pumping efficiency.

[0062] The presence of the air bladder space allows the simulated sucking liner 45 to adapt to different breast shapes and sizes. This adaptability can improve the fit between the breast pump and the breast, reduce air leakage, and ensure the efficiency and comfort of the breast pumping process.

[0063] Furthermore, the deformation of the 45-degree sucking liner can disperse and reduce direct pressure on the breast, reducing discomfort and pain during breastfeeding. The cushioning effect of the airbag space can distribute pressure more evenly on the surface of the breast, reducing discomfort caused by excessive local pressure.

[0064] Preferably, the simulated suction liner 45 and the breast bra 31 are connected by a cold-bonded hydroforming process. The cold-bonded hydroforming process can complete the connection at a lower temperature, which helps to maintain the original properties and strength of the material. Through this process, a precise and uniform bond can be achieved between the simulated suction liner 45 and the breast bra 31, improving the stability and durability of the entire structure.

[0065] Furthermore, the use of cold-bonded hydroforming can simplify the production process because it allows molding and joining to be completed at lower temperatures and pressures, reducing reliance on high-performance equipment. This not only improves production efficiency but also helps to reduce manufacturing costs.

[0066] In other embodiments, the sucking-inspired liner 45 and the breast bra 31 can also be integrally connected using other different processes, such as injection molding or ultrasonic welding.

[0067] Taking injection molding as an example, injection molding is a commonly used method for producing plastic products. By injecting molten plastic material into a specific mold, the overall structure of the imitation sucking liner 45 and the breast bra 31 can be formed in one go. The advantages of this process are high production efficiency, mass production capability, and good product consistency and precision.

[0068] Taking ultrasonic welding as an example, ultrasonic welding is a plastic joining method that does not require the use of additional adhesives. It uses the heat generated by high-frequency vibration to melt and fuse the contact surfaces of two plastic parts together. Ultrasonic welding can achieve a fast, efficient and environmentally friendly connection between the imitation suction liner 45 and the breast bra 31, while ensuring good sealing performance.

[0069] Preferred, such as Figures 1 to 8 As shown, the bra structure 3 in this embodiment is also provided with a positioning plate 33 corresponding to the breast pump host 2. The positioning plate 33 has an assembly groove 331 on one side. When the breast pump host 2 is assembled with the milk bowl 1, one side of the breast pump host 2 is installed in the assembly groove 331.

[0070] Preferably, the mounting groove 331 provides a dedicated mounting position for the breast pump main unit 2. When one side of the breast pump main unit 2 is embedded in the mounting groove 331, the edge of the groove can limit and fix the breast pump main unit 2 to a certain extent, preventing it from shifting or loosening during use. This ensures that the breast pump main unit 2 can be accurately aligned with the milk bowl 1 each time it is assembled, improving the assembly accuracy, avoiding performance problems caused by assembly deviation, and enhancing the stability of the connection.

[0071] Furthermore, embedding one side of the breast pump main unit 2 into the mounting groove 331 makes the entire product visually simpler and more unified. The groove design can hide the connection between the breast pump main unit 2 and the milk bowl 1, improving the product's aesthetics.

[0072] Furthermore, compared with other connection methods, the bra structure 3 in this embodiment is made of materials such as silicone or plastic. One side of the breast pump host 2 is embedded into the assembly groove 331, and the connection can be achieved by interference fit. This can reduce the volume and protrusion of the connection part, making the whole product more compact and saving space.

[0073] like Figures 1 to 8 As shown, the elastic suction-simulating inner lining airbag assembly 4 of this embodiment includes a breast massage part 47 and a nipple massage part 48. The bra structure 3 includes a breast suction channel 32. The nipple massage part 48 is located between the breast massage part 47 and the breast suction channel 32 and is connected to both of them.

[0074] Specifically, the breast massage section 47 massages the breasts through changes in air pressure, which helps stimulate the mammary glands, promote milk secretion, and relieve breast engorgement.

[0075] The nipple massage section 48 is specifically designed to stimulate and massage the nipples, mimicking the oral movements of a baby sucking. This helps stimulate the nipples, promotes milk flow, and improves milk extraction efficiency.

[0076] The combination of breast massage section 47 and nipple massage section 48 provides a more comprehensive massage experience, stimulating both the breast and nipple simultaneously, more closely resembling the natural sucking process of an infant, and helping to promote milk secretion and drainage.

[0077] like Figures 1 to 8 As shown, in this embodiment, the breast massage part 47 and the nipple massage part 48 are connected. The internal space of the breast massage part 47 gradually narrows along the nipple massage part 48 toward the outlet of the breast cover 31; that is, the internal space of the breast massage part 47 widens toward the nipple massage part 48.

[0078] With this design, at the connection between the breast massage section 47 and the nipple massage section 48, due to the structural changes of the two components, the pressure is concentrated in this area. This concentrated pressure effect can produce stronger stimulation to the tissues around the areola and nipple. The concentrated pressure stimulation of the areola and the tissues around the nipple can promote the discharge of milk from the mammary lobules and its smooth flow to the nipple. This mechanical stimulation better simulates the oral movements of an infant when sucking and helps to induce the milk descent reflex.

[0079] Furthermore, the pressure effect of the breast massage section 47 gradually increases from the outside to the inside, reaching its maximum at the connection with the nipple massage section 48. This progressive massage action can gradually reduce the pressure on the breast during the massage process, thereby avoiding excessive compression of the mammary glands, reducing discomfort, and effectively stimulating the entire breast to promote milk production and drainage.

[0080] As the internal space of the breast massage section 47 gradually widens, the transition from breast massage to nipple massage becomes more natural, reducing sudden pressure on the nipple and breast, making the breastfeeding process more comfortable.

[0081] Furthermore, the gradually widening design of the internal space of the breast massage section 47 reduces the pressure on the breast during the deformation process, making the entire breast pumping process more comfortable, especially for mothers with sensitive breasts.

[0082] Furthermore, the concentrated pressure effect simulates the oral movements of an infant sucking, making the breastfeeding process closer to natural breastfeeding and helping to maintain the mother's milk production capacity.

[0083] Preferably, the nipple massage portion 48 includes the upper lip of the inner lining 41 and the lower lip of the inner lining 42 (such as a sucking-like inner lining 45); or, the elastic sucking-like inner lining airbag assembly 4 formed by combining the nipple massage portion 48 and the breast massage portion 47 includes the upper lip of the inner lining 41 and the lower lip of the inner lining 42 (such as a sucking-like inner lining 45), and a suitable design can be selected according to actual needs.

[0084] like Figures 1 to 8 As shown, the breast pump main unit 2 of this embodiment includes a sealed housing 21, an air source device 22 is also provided with an air intake end 223, the air intake end 223 is provided with an air intake pipe 224, the milk bowl 1 is provided with a negative pressure chamber 11, the breast shield structure 3 includes a milk suction channel 32 located in the negative pressure chamber 11, and an air suction channel 8 is provided between the sealed housing 21 and the negative pressure chamber 11 to communicate with the air intake pipe 224 and the negative pressure chamber 11.

[0085] Specifically, the air source device 2 draws out air from the negative pressure chamber 11 through the air intake end 223 and the air intake pipe 224, so that the negative pressure chamber 11 forms a negative pressure, thereby causing the milk suction channel 32 or the deformable structure of the milk suction channel 32 (such as the suction bowl) in the negative pressure chamber 11 to expand elastically. Then, the air source device 2 introduces air into the negative pressure chamber 11 through the air intake end 223 and the air intake pipe 224, so that the negative pressure chamber 11 in the milk bowl 1 returns to atmospheric pressure, thereby causing the milk suction channel 32 or the deformable structure of the milk suction channel 32 (such as the suction bowl) in the negative pressure chamber 11 to contract elastically and return to its original state. This process is repeated.

[0086] Specifically, the breast pump channel 3 mainly provides negative pressure for milk suction, while the elastic sucking-simulating inner airbag assembly 4 provides squeezing massage. Together, they simulate the oral movements and rhythm of an infant sucking. Through the synergistic effect of negative pressure suction and squeezing massage, the mammary gland tissue can be effectively stimulated, promoting milk secretion and discharge, and improving milk suction efficiency. The breast pump channel 3 and the elastic sucking-simulating inner airbag assembly 4 work together to further mimic the infant's sucking movements. Furthermore, the elastic deformation of the breast pump channel 32 or the deformation structure of the breast pump channel 32 allows milk to enter the milk storage space in the milk bowl 1 for collection.

[0087] like Figures 1 to 8 As shown, the gas source device 22 in this embodiment is provided with a gas delivery end 221. The gas delivery end 221 is provided with a gas delivery pipe 222 that communicates with the gas delivery channel 5. The gas delivery pipe 222 is provided with a heating module 6 that can heat the gas delivered by the gas delivery pipe.

[0088] Specifically, the air source device 22 is responsible for providing compressed or pressurized air. Since the air source device 22 also generates heat during operation, it preheats the gas so that the gas has a certain initial temperature before being transported through the air delivery pipe 222. However, the gas temperature will drop during the process of being transported to the elastic imitation suction liner airbag assembly 4 (such as the upper liner 41 and the lower liner 42). Therefore, a heating module 6 is added at the air delivery pipe 222. The heating module 6 heats the gas to raise its temperature to a suitable level. The heated gas reaches the elastic imitation suction liner airbag assembly 4 (upper liner 41 and lower liner 42) through the air delivery channel 5.

[0089] Furthermore, the breast pump main unit 2 is also equipped with a control component 23, which can adjust the power of the heating module 6 as needed to maintain the gas temperature within the optimal range.

[0090] Preferably, the heating module 6 can be a PTC heater or a heating film (whose material composition can be graphene combined with a flexible sensor, or carbon fiber, or conductive ink, or carbon-based material coated on an insulating silicone substrate, for uniform heating, thinness, and flexible design). The heating module 6 is assembled on the air delivery pipe 222 and can be controlled by the control component 23 (such as a circuit board) to heat the heating module 6. The heated air is delivered through the air delivery pipe 222 to the air supply channel 5 and reaches the elastic suction-simulating inner lining airbag assembly 4 (such as the inner lining upper lip 41 and inner lining lower lip 42), causing the temperature inside the elastic suction-simulating inner lining airbag assembly 4 (such as the inner lining upper lip 41 and inner lining lower lip 42) to rise. Taking the inner lining upper lip 41 and inner lining lower lip 42 as an example, the gas can cause the inner lining upper lip 41 and inner lining lower lip 42 to expand, and the gas has a certain temperature, so that the inner lining upper lip 41 and inner lining lower lip 42 have a certain temperature, providing a hot compress and massage effect to the breast, promoting blood circulation, and relieving discomfort symptoms.

[0091] Furthermore, applying heat can relax breast tissue, thereby enhancing the massage effect of the inner airbag and improving the comfort of breastfeeding. The appropriate temperature of the heat application can also promote milk secretion and flow, thus improving the efficiency of breastfeeding.

[0092] Furthermore, applying heat can help relieve discomfort such as swelling and pain caused by mastitis, providing soothing and treatment for mothers.

[0093] like Figures 1 to 8 As shown, the air outlet of the air supply pipe 222 in this embodiment is provided with a temperature detection component 7 electrically connected to the heating module 6. The temperature detection component 7 can monitor the air temperature at the air outlet of the air supply pipe 222 in real time. The temperature detection component 7 sends the measured temperature data to the control component 2. The control component 23 adjusts the heating power of the heating module 6 according to the preset temperature range and the currently measured temperature. The heating module 6 adjusts the heating intensity according to the instructions of the control component 23, so that the air temperature at the air outlet of the air supply pipe 222 is maintained within the optimal range. The stable hot air reaches the elastic suction-like inner lining airbag component 4 through the air supply channel 5, providing the best heat therapy effect for the breast.

[0094] Specifically, the temperature detection component 7 can monitor the air temperature at the air outlet of the air supply pipe 222 in real time, providing timely and accurate data feedback for temperature control. The control component 23 can automatically adjust the heating power of the heating module 6 based on the feedback data from the temperature detection component 7, without requiring manual intervention from the user, making it more convenient to use.

[0095] Furthermore, through real-time monitoring and automatic adjustment, the system can ensure that the air temperature delivered to the inner lining airbag is always within the optimal range, providing a stable and efficient heat therapy effect.

[0096] Furthermore, the temperature detection component 7 in this embodiment includes a temperature sensor arranged around the air outlet near the air outlet of the air supply pipe 222. The air outlet of the air supply pipe 222 is connected to the air delivery channel 5. With this design, the gas temperature at the air outlet of the air supply pipe 222 can be monitored in real time, and the heating power of the heating module 6 can be adjusted in a timely manner through the control component 23. This can effectively prevent the gas temperature from being too high or too low, and avoid causing discomfort or damage to the breast.

[0097] Preferably, the temperature detection component 7 can also be a temperature probe inserted into the gas delivery pipe 222, and a suitable design can be selected according to actual needs.

[0098] like Figures 1 to 8 As shown, the air source device 22 in this embodiment includes an integrated pump and valve air pump. Specifically, by integrating the air pump and valve into one unit, the structure of the air source device 22 can be simplified, the number of parts can be reduced, and the reliability can be improved. Furthermore, the integrated pump and valve design makes the air source device 22 more compact, which is convenient to integrate into the breast pump and improves the portability of the whole machine.

[0099] Specifically, by adopting the design of the sealed housing 21, the sealed housing 21 forms a sealed air tank, and the internal space is in a state similar to a vacuum. When the air pump is working, air can be drawn out from the negative pressure chamber 11 through the air intake end 223 and the air intake pipe 224, so that the negative pressure chamber 11 forms a negative pressure. At the same time, air can be delivered to the elastic imitation suction liner airbag assembly 4 through the air delivery end 221 and the air delivery pipe 222, so that the elastic imitation suction liner airbag assembly 4 expands elastically. That is, in this embodiment, when the elastic imitation suction liner airbag assembly 4 is under positive pressure, the negative pressure chamber 11 is under negative pressure; when the elastic imitation suction liner airbag assembly 4 is under negative pressure, the negative pressure chamber 11 is under positive pressure. The design of the sealed housing 21 being in a state similar to a vacuum can minimize the impact on the air pressure of the air source device 22, so that the air pressure between the negative pressure chamber 11 and the elastic imitation suction liner airbag assembly 4 reaches a balanced state.

[0100] When the air pump stops working, the valve opens, and air can be injected into the negative pressure chamber 11 through the air intake end 223 and the air intake pipe 224, so that the pressure in the negative pressure chamber 11 returns to atmospheric pressure.

[0101] The air inside the elastic suction-simulating inner liner airbag assembly 4 can also be discharged through the air inlet 221 and the air delivery pipe 222, so that the elastic suction-simulating inner liner airbag assembly 4 can elastically contract and return to its original shape.

[0102] By alternating the operation of the air pump and valve, the pressure in the negative pressure chamber 11 changes periodically between negative pressure and atmospheric pressure, thereby driving the periodic elastic deformation of the breast pumping channel 32 or its deformable structure (such as the suction bowl).

[0103] Furthermore, by alternating the operation of the air pump and valve, the pressure inside the elastic suction-simulating liner airbag assembly 4 changes periodically between positive pressure and atmospheric pressure, thereby driving the periodic elastic deformation of the elastic suction-simulating liner airbag assembly 4.

[0104] Preferably, in other embodiments, the air source device 22 can employ an independent air pump and a solenoid valve, with the air pump and solenoid valve being set separately. The air pump provides the functions of suction and inflation, and the solenoid valve controls the airflow direction. Typically, two solenoid valves are set, one controlling the suction pipe 224 and the other controlling the delivery pipe 222. By controlling the opening and closing of the corresponding solenoid valves, the periodic change of pressure in the negative pressure chamber 11 or the elastic imitation suction liner airbag assembly 4 can be achieved. A suitable design can be selected according to actual needs.

[0105] like Figures 1 to 8 As shown, the sealed housing 21 in this embodiment includes an upper housing 211 and a lower housing 212. The upper housing 211 and the lower housing 212 are seamlessly sealed together by ultrasonic welding or hot melting, so that the breast pump main unit 2 forms a sealed air tank space. The air source device 22 is installed inside the sealed housing 21, isolating it from the external environment and forming an independent functional unit. This ensures the high sealing performance of the sealed housing 21, and the highly sealed housing 21 can effectively isolate the influence of the external environment, such as humidity and dust, thereby improving the reliability and service life of the breast pump.

[0106] Furthermore, placing the air source device 22 inside the breast pump main unit 2 can effectively isolate the noise generated when the air pump is working, improve the quietness performance of the breast pump, and the good sound insulation effect can create a quiet and comfortable breast pumping environment for the mother, reducing interference to the baby and others.

[0107] Furthermore, the breast pump main unit 2, resembling a sealed air canister, provides a relatively independent and stable air pressure environment. This facilitates the air source device 22 in precisely controlling the magnitude and variation of air pressure. Specifically, once the breast pump is assembled, the sealed housing 21, the elastic, simulated-sucking inner airbag assembly 4, and the negative pressure chamber 11 form a completely sealed air canister structure, providing a stable working environment for the air source device and reducing the impact of external air pressure fluctuations on the pump's performance. This design allows the pump to more precisely control the air pressure in the negative pressure chamber and the simulated-sucking inner airbag, thereby better simulating the natural sucking rhythm and intensity.

[0108] Furthermore, in a sealed and controlled system, the air pump responds to pressure adjustments more quickly and can instantly respond to changes in the control system's commands. This is crucial for breast pumps that need to quickly switch pressures to adapt to different sucking stages.

[0109] Furthermore, it ensures proper air pressure control within the breast pump unit 2, preventing safety issues caused by improper pressure, such as excessive inflation and rupture of the airbag, thus ensuring user safety during use.

[0110] like Figures 1 to 8 As shown, the sealed housing 21 of this embodiment is also provided with a pressure detection element 9 that is electrically connected to the gas source device 22.

[0111] Preferably, the pressure detection element 9 includes a pressure sensor mounted on the circuit board. The pressure sensor on the circuit board can detect the air pressure in the sealed housing 21 in real time when the air source device 22 is venting or inhaling air in the sealed housing 21. This allows for real-time control of the solenoid valve of the air source device 22 and adjustment of the intake pressure, causing the elastic sucking-simulating inner liner airbag assembly 4 to bulge out and mimic the sucking action of an infant, thereby stimulating the mammary glands to secrete milk.

[0112] Furthermore, real-time monitoring by pressure sensors can promptly detect abnormal air pressure, such as excessively high or low pressure. This early warning can trigger safety protection mechanisms, such as automatically shutting down the air pump or releasing pressure, to prevent equipment damage or user injury.

[0113] Furthermore, the data recorded by the pressure sensor can be used to analyze different users' pumping patterns and pressure preferences. Based on this data, personalized pumping settings can be provided to users to meet their specific needs.

[0114] Example 2:

[0115] The difference between Example 2 and Example 1 is as follows:

[0116] like Figures 9 to 13 As shown, the elastic suction-simulating liner airbag assembly 4 of this embodiment also includes a liner seat 46 connected to the suction-simulating liner 45, and the liner seat 46 is detachably connected to the bra structure 3.

[0117] Specifically, the elastic sucking-simulating liner airbag assembly 4 consists of a sucking-simulating liner 45 and a liner seat 46. The liner 45 directly contacts the mother's breast, mimicking the sucking action of an infant, while the liner seat 46 is used to fix the liner 45 and connects to the bra structure 3.

[0118] Furthermore, the detachable connection between the lining seat 46 and the bra structure 3 allows users to easily remove or install the lining airbag assembly 4 from the bra structure 3. This connection is typically achieved through snaps, latches, threaded engagement, or other quick-connect mechanisms. In this embodiment, the lining seat 46 is provided with a connecting seat 461, and the breast suction channel 32 of the bra structure 3 is provided with a connecting slot 321. Since the breast suction channel 32 has a certain elasticity, the connecting slot is also elastic. The connecting slot holds the connecting seat in place, so that the lining seat 46 is connected to the bra structure 3. A suitable design can be selected according to actual needs.

[0119] Preferably, the detachable design of the inner lining airbag assembly 4 makes cleaning and disinfection more convenient. Users can easily remove the inner lining airbag assembly from the bra structure for thorough cleaning and drying, ensuring hygienic and safe use.

[0120] Furthermore, if the inner airbag assembly needs to be replaced or a new, improved version is available, users can simply replace the inner airbag assembly without replacing the entire breast pump device, which provides greater cost-effectiveness and a better user experience.

[0121] Furthermore, different users may require linings of different sizes or shapes. The removable design allows users to choose the appropriate lining airbag components according to their individual needs, increasing the product's applicability and user satisfaction.

[0122] The simulated suction liner 45 and the liner seat 46 are connected by a cold-bonded hydraulic forming process. Alternatively, processes such as injection molding or ultrasonic welding can be used, and a suitable design can be selected according to actual needs.

[0123] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
