Description

Technical Field

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

[0002] A breast pump is a device that helps breastfeeding mothers collect breast milk more conveniently. It uses negative pressure to draw milk from the breast and collect it by simulating the sucking action of a baby. There are many types of breast pumps on the market, both manual and electric, but most breast pumps have certain shortcomings in the design of the bra structure.

[0003] The bras used in existing breast pumps are usually made of materials such as silicone or plastic. Their main function is to form a seal against the breast and transfer suction to the nipple. However, these bras can make the nipples feel cold during use and cannot provide a warm environment similar to that of a baby's mouth. Many users have reported that the cold bras affect milk flow and make the milk expression process less comfortable.

[0004] In addition, milk fat tends to solidify at lower temperatures, clogging milk ducts and affecting milk expression. Some studies have shown that moderate heating of the breast helps stimulate milk secretion and makes milk flow smoother, but most current breast pumps do not have integrated heating elements, so they cannot provide heating during the milk expression process.

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

[0006] Regarding the aforementioned technical issue that most current breast pump products do not integrate heating elements, thus failing to provide warmth during the breast pumping process.

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

[0008] A heated breast pump includes a milk bowl, a breast pump main unit connected to the milk bowl, and a breast shield structure. The breast shield structure has an inflation space. The breast pump main unit includes an air source device and a heating module. The air source device is connected to the inflation space, and the heating module can heat the gas supplied by the air source device to the inflation space.

[0009] As described above, in a heated breast pump, the air source device is provided with an air delivery end, the air delivery end is provided with an air supply pipe communicating with the inflation space, and the heating module is connected to the air supply pipe.

[0010] As described above, in a heated breast pump, the heating module includes a PTC heater or a heating film.

[0011] As described above, the breast pump main unit is further provided with a control component electrically connected to the heating module, and the control component is capable of adjusting the power of the heating module.

[0012] As described above, in a heated breast pump, a temperature detection component electrically connected to the heating module is provided at the air outlet of the air delivery pipe.

[0013] In the breast pump described above, the heating module is located near the temperature detection component in the air delivery pipe.

[0014] As described above, in a heated breast pump, the air source device includes an integrated pump and valve air pump.

[0015] As described above, the main unit of the breast pump also includes a sealed housing, the air source device and the heating module are both located inside the sealed housing, and an air supply channel is provided between the sealed housing and the breast shield structure to connect the air source device and the inflation space.

[0016] As described above, in a heated breast pump, the bra structure includes an elastic, simulated sucking liner airbag assembly. The inflation space is located within the elastic, simulated sucking liner airbag assembly. When the air source device draws in or inflates the inflation space, the elastic, simulated sucking liner airbag assembly deforms under the air pressure within the inflation space to achieve expansion or contraction.

[0017] As described above, the breast shield structure of the heated breast pump also includes a breast shield, and the elastic, sucking-inducing inner liner airbag assembly and the breast shield are integrally molded.

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

[0019] This utility model relates to a heated breast pump, specifically a breast pump technical field. It includes a milk bowl, a breast pump main unit connected to the milk bowl, and a breast shield structure. The breast shield structure has an inflatable space. The breast pump main unit includes an air source device and a heating module. The air source device is connected to the inflatable space, and the heating module heats the gas supplied to the inflatable space by the air source device. Thus, warm gas flows into the breast shield structure, filling the inflatable space and providing a warm, enveloping effect on the breast. This heat helps relax the breast and promotes blood circulation. The heating function of the breast pump increases the temperature of the breast area, helping to dilate blood vessels and improve blood circulation. Good blood circulation helps the mammary glands secrete milk more effectively, increasing the efficiency of milk extraction.

[0037] Example 1:

[0038] like Figures 1 to 8 As shown, a heated breast pump according to this embodiment includes a milk bowl 1, a breast pump main unit 2 and a bra structure 3 respectively connected to the milk bowl 1. The bra structure 3 is provided with an inflation space 30. The breast pump main unit 2 includes an air source device 22 and a heating module 6. The air source device 22 is connected to the inflation space 30. The heating module 6 can heat the gas delivered to the inflation space 30 by the air source device 22, thereby heating the bra structure, providing a heat therapy effect to the breast, promoting blood circulation, and relieving discomfort symptoms.

[0039] Specifically, the air source device in the breast pump unit is responsible for generating gas. This gas is delivered to the inflation space inside the bra structure through connecting pipes. Before the gas enters the inflation space, the heating module heats the gas. In this way, warm gas flows into the bra structure and fills the inflation space of the bra, so that the entire bra structure has a warm enveloping effect on the breast. This heat can help the breast relax and promote blood circulation.

[0040] The heating function of the breast pump's bra structure 3 can raise the temperature of the breast area, thereby helping to dilate blood vessels and improve blood circulation. Good blood circulation helps the mammary glands secrete milk better, improving the efficiency of milk expression.

[0041] like Figures 1 to 8 As shown, the gas source device 22 in this embodiment is provided with a gas delivery end 221, and the gas delivery end 221 is provided with a gas delivery pipe 222 communicating with the gas filling space 30. The heating module 6 is connected to the gas delivery pipe 222.

[0042] 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 inflation space 30. 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 inflation space 30 through the air delivery channel 5.

[0043] 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.

[0044] Preferably, the heating module 6 can be a PTC heater or a heating film (the 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, which is designed to be uniform in heating, thin, and flexible). The heating module 6 is mounted on the air supply 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 then sent through the air supply pipe 222 to the air supply channel inflation space 30, which raises the temperature of the bra structure, provides a heat therapy effect to the breast, promotes blood circulation, and relieves discomfort symptoms.

[0045] like Figures 1 to 8 As shown, in this embodiment, the air outlet of the air supply pipe 222 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 inflation space 30 through the air supply channel 5, providing the best heat therapy effect for the breast.

[0046] 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.

[0047] Furthermore, through real-time monitoring and automatic adjustment, the system can ensure that the air temperature delivered to the inflatable space 30 is always within the optimal range, providing a stable and efficient heat therapy effect.

[0048] 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.

[0049] 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.

[0050] Preferably, in this embodiment, the heating module 6 is located near the temperature detection component 7 in the gas supply pipe 222, ensuring that the heated gas can be quickly transferred to the detection area. The temperature detection component 7 monitors the temperature of the heated gas in real time and feeds the data back to the control system to achieve precise temperature control.

[0051] Furthermore, the heating module 6 is located near the inlet of the gas supply pipe 222, which enables it to heat the gas quickly, reduce heat loss, and improve heating efficiency.

[0052] 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.

[0053] like Figures 1 to 8 As shown, the bra structure 3 of this embodiment includes an elastic, suction-simulating inner lining airbag assembly 4. The inflation space 30 is located within the elastic, suction-simulating inner lining airbag assembly 4, that is, the inflation space 30 is the internal space of the elastic, suction-simulating inner lining airbag assembly 4. With this design...

[0054] With this design, when the air source device 22 draws in or inflates the inflation space 30 through the air supply channel 5, the elastic sucking-like inner liner airbag assembly 4 deforms under the action of air pressure to achieve deformation expansion or deformation contraction, producing an effect similar to a baby sucking; and, combined with the heating module heating the gas, the elastic sucking-like inner liner airbag assembly 4 has a certain temperature, providing a hot compress and massage effect to the breast, promoting blood circulation and relieving discomfort symptoms.

[0055] Furthermore, by controlling the air supply device's inflation and deflation process, 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.

[0056] The mimicking of a baby's sucking motion 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 to the single negative pressure mode of traditional breast pumps, this biomimetic design is more conducive to improving lactation efficiency.

[0057] 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.

[0058] 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.

[0059] 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, wherein the upper liner 41, the left liner 43, the lower liner 42 and the right liner 44 are arranged in sequence to form a simulated sucking liner 45.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Furthermore, the interval design allows the breast pump to provide targeted stimulation to specific areas of the breast.

[0073] like Figures 1 to 8 As shown, the bra structure 3 in this embodiment also includes a breast cover 31, and the elastic suction-simulating inner lining airbag assembly 4 and the breast cover 31 are integrally molded structures.

[0074] Preferably, the one-piece molded structure eliminates the connecting parts between the elastic sucking liner airbag assembly 4 and the breast shield 31, 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.

[0075] Furthermore, the one-piece molding design avoids any gaps that may exist between the elastic, sucking-like inner liner airbag assembly 4 and the breast shield 31, thus providing better sealing performance. This not only improves milk expression efficiency but also prevents milk leakage, ensuring hygiene and safety during the milk expression process.

[0076] Furthermore, the seamless integration of the elastic, suction-simulating inner liner airbag assembly 4 with the breast shield 31 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.

[0077] Furthermore, in this embodiment, the elastic suction-simulating inner lining airbag assembly 4 and the breast bra 31 are integrally molded, and the inner wall of the elastic suction-simulating inner lining airbag assembly 4 and the side wall of the breast bra 31 are enclosed to form

[0078] The air supply device 22 is connected to the air supply space 30 through the air supply channel 5. By controlling the air supply device 22 to supply air to the air supply space 30, the elastic sucking-simulating inner liner airbag assembly 4 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.

[0079] Preferably, the elastic, suction-simulating inner lining airbag assembly 4 and the breast bra 31 are connected by a cold-bonding hydroforming process. The cold-bonding 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, precise and uniform bonding can be achieved between the elastic, suction-simulating inner lining airbag assembly 4 and the breast bra 31, improving the stability and durability of the entire structure.

[0080] 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.

[0081] In other embodiments, the elastic suction-like inner lining airbag assembly 4 and the breast bra 31 can also be integrally connected using other different processes, such as injection molding, ultrasonic welding, etc.

[0082] 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 elastic imitation sucking liner airbag component 4 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.

[0083] 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 elastic suction-like inner lining airbag assembly 4 and the breast bra 31, while ensuring good sealing performance.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] like Figures 1 to 8 As shown, the air source device 22 in this embodiment 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 sealing shell 21 and the negative pressure chamber 11 to connect the air suction pipe 224 with the negative pressure chamber 11.

[0100] 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.

[0101] 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.

[0102] like Figures 1 to 8 As shown, the breast pump main unit 2 in this embodiment also includes a sealed housing 21. The gas source device 22 and the heating module 6 are both located inside the sealed housing 21. The design of the sealed housing 21 can minimize the loss of gas temperature and ensure that the heating module 6 heats the gas.

[0103] Furthermore, an air supply channel 5 is provided between the sealed housing 21 and the bra structure 3 to connect the air source device 22 and the inflation space 30, which can ensure the sealing performance between the air source device 22 and the inflation space 30.

[0104] Furthermore, by adopting the design of the sealed housing 21, the sealed housing 21 forms a sealed air tank design, 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 is in a negative pressure state. At the same time, air can be delivered to the inflation space 30 through the air delivery end 221 and the air delivery pipe 222, so that the elastic suction-like inner liner airbag assembly 4 expands elastically. That is, in this embodiment, when the inflation space 30 is in a positive pressure state, the negative pressure chamber 11 is in a negative pressure state; when the inflation space 30 is in a negative pressure state, the negative pressure chamber 11 is in a positive pressure state. Moreover, by adopting the design of the sealed housing 21 being in a state similar to a vacuum state, the influence on the air pressure of the air source device 22 can be minimized, so that the air pressure between the negative pressure chamber 11 and the inflation space 30 reaches a balanced state.

[0105] 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.

[0106] Air can also be discharged from the inflation space 30 through the air supply end 221 and the air delivery pipe 222, so that the elastic imitation suction liner airbag assembly 4 can elastically contract and return to its original shape.

[0107] 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).

[0108] Furthermore, by alternating the operation of the air pump and valve, the pressure within the inflation space 30 is periodically changed between positive pressure and atmospheric pressure, thereby driving the periodic elastic deformation of the elastic suction-simulating inner liner airbag assembly 4.

[0109] 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 within the negative pressure chamber 11 or the inflation space 30 can be achieved. A suitable design can be selected according to actual needs.

[0110] like Figures 1 to 8As 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.

[0111] 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.

[0112] Furthermore, the breast pump main unit 2, resembling a sealed air tank, 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 inflation space 30, and the negative pressure chamber 11 form a completely sealed air tank 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 liner airbag, thereby better simulating the natural sucking rhythm and intensity.

[0113] Furthermore, in a sealed and controlled system, the air pump responds to pressure adjustments more quickly and can respond instantly to changes in the control system's commands. This is crucial for breast pumps that need to quickly switch pressures to adapt to different stages of sucking.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Example 2:

[0120] The difference between Example 2 and Example 1 is as follows:

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.
