Description

Technical Field

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

[0002] Traditional integrated breast pumps are typically driven by electricity or manual force and extract milk through negative pressure. Their core structure includes a power unit, a breast shield, and a milk storage container. The design goals are primarily portability and ease of operation. However, a significant drawback of existing technologies is the lack of dynamic simulation of a baby's natural sucking motion.

[0003] From a physiological perspective, infant sucking is a complex, cyclical process that includes two key stages:

[0004] 1) The oral negative pressure formation stage (sucking period) is achieved through the coordinated action of the tongue and palate to generate negative pressure;

[0005] 2) During the squeezing stimulation stage (swallowing period), the areola area is regularly pressed by jaw movement. Traditional integrated breast pumps mostly use a single negative pressure mode, which can only simulate the vacuum effect during the sucking period and cannot reproduce the mechanical squeezing stimulation during the swallowing period.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] This addresses the technical problem mentioned above where traditional all-in-one breast pumps lack dynamic simulation of a baby's natural sucking motion.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A wearable breast pump that mimics sucking includes a milk bowl, a sucking component, a milk bowl cover connected to the milk bowl, and a breast pump main unit. The milk bowl cover has a milk suction channel, and the sucking component is detachably connected to the milk suction channel. The breast pump main unit has an air source device, and the milk bowl has a positive pressure air path that allows the sucking component and the air source device to communicate. When the air source device inflates or deflates the sucking component through the positive pressure air path, the sucking component can deform within the milk suction channel to achieve expansion or contraction.

[0010] As described above, a wearable breast pump that mimics sucking includes at least two spaced flexible airbags, with a space between the flexible airbags for accommodating the nipple; the outer wall of each flexible airbag is close to or abuts against the inner wall of the breast pumping channel.

[0011] As described above, the wearable breast pump that mimics sucking has two flexible airbags, and each of the flexible airbags has an arc-shaped cross-section.

[0012] As described above, the wearable breast pump that mimics sucking includes a mounting bracket, each of the flexible airbags is connected to the mounting bracket, the mounting bracket has a through hole in the middle communicating with the receiving space, and the mounting bracket has air passages communicating with the positive pressure air passage and the flexible airbag respectively.

[0013] As described above, a wearable breast pump that mimics sucking has an air passage comprising an annular air passage communicating with a positive pressure air passage and multiple airbag air passages communicating with the annular air passage, wherein the airbag air passages are correspondingly arranged with flexible airbags.

[0014] As described above, a wearable breast pump that mimics sucking has an air source device comprising an air pump, an exhaust assembly, and a positive pressure pipeline component. The positive pressure pipeline component has a first air delivery end, a first air inlet end, and a first exhaust end. The first air delivery end is connected to a positive pressure air path, and the first exhaust end is connected to the exhaust assembly. The air pump has a positive pressure air outlet end connected to the first air inlet end.

[0015] As described above, in a wearable breast pump that mimics sucking, the venting assembly includes a first solenoid valve and a pressure detection element. The pressure detection element is electrically connected to the first solenoid valve and the air pump, respectively. When the pressure detection element detects that the air pressure in the positive pressure pipeline component reaches a predetermined threshold, the pressure detection element can control the air pump's inflation flow rate and control the first solenoid valve to vent.

[0016] As described above, a wearable breast pump that mimics sucking has a negative pressure chamber and a negative pressure air passage inside the milk bowl. The milk suction channel is located inside the negative pressure chamber and has a deformable structure. The air source device also includes an air suction component and a negative pressure pipe component.

[0017] As described above, a wearable breast pump that mimics sucking has a negative pressure pipe component with a first suction end, a second suction end, and a second air inlet end. The first suction end is connected to the negative pressure air path, the second air inlet end is connected to the suction assembly, and the air pump has a negative pressure suction end connected to the second suction end.

[0018] As described above, the wearable breast pump that mimics sucking is further provided with a control component and a power supply component. The power supply component includes a power supply battery located inside the breast pump and a charging port located on one side of the breast pump.

[0019] The beneficial effects of this utility model are:

[0020] This utility model relates to a wearable breast pump that mimics sucking, and relates to the field of breast pump technology. It includes a milk bowl, a sucking component, a milk bowl cover connected to the milk bowl, and a breast pump main unit. The milk bowl cover has a milk suction channel, and the sucking component is detachably connected to the milk suction channel. The breast pump main unit contains an air source device. The milk bowl has a positive pressure air path that connects the sucking component and the air source device. The air source device is connected to the sucking component through the positive pressure air path and can inflate or deflate the sucking component. When the air source device inflates the sucking component, the sucking component deforms and expands within the milk suction channel, squeezing the nipple, simulating the jaw pressing action of an infant during swallowing. Through repeated inflation and deflation, the sucking component continuously deforms, expands, and contracts within the milk suction channel. By simulating the sucking action of an infant, it can stimulate the mother's pituitary gland to secrete prolactin, thereby increasing milk production and meeting the infant's nutritional needs.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0034] like Figures 1 to 9 As shown, this embodiment of a wearable breast pump that mimics sucking includes a milk bowl 1, a sucking component 4, a milk bowl cover 2 connected to the milk bowl 1, and a breast pump main unit 3. The milk bowl cover 2 is provided with a milk suction channel 21, and the sucking component 4 is detachably connected to the milk suction channel 21. The breast pump main unit 3 is provided with an air source device 5. The milk bowl 1 is provided with a positive pressure air passage 11 that allows the sucking component 4 and the air source device 5 to communicate. Specifically, the air source device 5 is connected to the sucking component 4 through the positive pressure air passage 11 and can inflate or deflate the sucking component 4. When the air source device 5 inflates the sucking component 4, the sucking component 4 will deform and expand within the milk suction channel 21, squeezing the nipple, simulating the jaw pressing action during the infant's swallowing period.

[0035] When the air source device 5 releases air from the suction component 4, the suction component 4 will deform and contract within the milk suction channel 21 to simulate the action of an infant sucking on a nipple, thus completing one sucking cycle.

[0036] Through repeated inflation and deflation, the sucking component 4 can continuously deform, expand, and contract within the milk suction channel 21, simulating the rhythm and force of a baby sucking on the nipple. By deforming, expanding, and contracting, the sucking component 4 can more realistically simulate the action and rhythm of a baby sucking on the nipple, providing a more natural breastfeeding experience.

[0037] Furthermore, by simulating the sucking motion of an infant, the mother's pituitary gland can be stimulated to secrete prolactin, thereby increasing the amount of breast milk produced and meeting the infant's nutritional needs.

[0038] Furthermore, the suction component 4 in this embodiment can be detached from the milk suction channel 21 for easy cleaning and replacement, ensuring the hygiene and maintenance of the breast pump.

[0039] In addition to adding a sucking function, this breast pump still retains the basic functions of a traditional breast pump, and can collect and store breast milk through the milk bowl 1 and the breast pump main unit 3.

[0040] like Figures 1 to 9 As shown, the sucking component 4 of this embodiment includes at least two spaced flexible airbags 41, and there is a receiving space 42 between the plurality of flexible airbags 41 to receive the nipple.

[0041] Specifically, two or more flexible airbags 41 are periodically inflated and deflated under the control of the air source device 5. The inflation and deflation of each airbag can be controlled independently or synchronously, and a suitable design can be selected according to actual needs.

[0042] When the flexible airbags 41 are inflated, they expand inward, applying slight pressure to the nipple within the receiving space 42, simulating the suction force of a baby sucking. When deflated, the airbags contract, reducing the pressure on the nipple, simulating the relaxation phase of a baby sucking. By controlling the inflation and deflation of the airbags, the rhythm and force of a baby sucking can be precisely simulated, adjustable from rapid shallow sucking to deep sucking.

[0043] Furthermore, by using two or more spaced flexible airbags, this design can more accurately simulate the sucking motions and strength of an infant, thereby more effectively stimulating the mammary glands and promoting milk secretion. This spaced airbag design can reduce continuous pressure on the nipple, making it closer to the feeling of natural breastfeeding than traditional breast pumps, reducing pain and discomfort, and improving the comfort of breastfeeding.

[0044] Furthermore, the spacing between the flexible airbags ensures that each airbag has enough space to deform and expand when inflated, without being restricted or squeezed by adjacent airbags. This allows the airbags to more freely simulate the movements and strength of a baby's sucking. In addition, when the airbags have enough room to deform, they can generate greater pressure and suction when inflated, more effectively stimulating the mammary glands, promoting the release and flow of milk, and thus improving the efficiency of milk expression.

[0045] Ample deformation space allows the airbag to deform and move more noticeably when inflated, more closely resembling the movements of a baby's mouth and tongue when sucking. This realism provides mothers with a more natural breastfeeding experience and reduces user discomfort.

[0046] Furthermore, ample deformation space can reduce mutual interference and wear between airbags, and prevent airbags from being squeezed or damaged during repeated inflation and deflation, thereby extending the service life of the suction components.

[0047] Furthermore, the spacing not only provides deformation space for the airbags, but also makes the internal structure of the suction components more open, facilitating cleaning and maintenance. Mothers can more easily disassemble and clean each airbag, ensuring the hygiene of the breast pump.

[0048] Furthermore, the reasonable spacing setting provides more flexibility in the design of the sucking component, allowing designers to adjust the number, size, and spacing of the airbags as needed to optimize the sucking effect and adapt to the needs of different mothers.

[0049] Furthermore, due to the presence of the accommodating space 42, the design can accommodate nipples of different sizes and shapes, increasing the versatility and adaptability of the breast pump.

[0050] like Figures 1 to 9 As shown, the number of flexible airbags 41 in this embodiment is two, and the cross-sectional shape of each flexible airbag 41 is arc-shaped. Preferably, each flexible airbag 41 in this embodiment is an elongated arc shape, and the cross-sectional shape of each flexible airbag 41 presents an arc shape similar to that of a baby's lips. When the airbag is inflated, this shape can more naturally fit the breast and nipple, simulating the wrapping and sucking action of a baby's lips.

[0051] Furthermore, the coordinated operation of the two flexible airbags 41 can better simulate the movements of an infant's upper and lower lips when sucking, similar to the coordinated movements of an infant's upper and lower lips when sucking.

[0052] The flexible airbag 41 features a rounded cross-sectional design, which allows the suction to be distributed more evenly around the nipple and areola, avoiding excessive pressure at any one point and reducing discomfort.

[0053] The rounded airbag design provides a gentler, more natural sucking sensation, reducing stimulation and pressure on the breasts and nipples, making mothers more comfortable when using the breast pump. The shape of the airbag and the synergistic work of the two airbags can more effectively stimulate the mammary glands, promote the release and drainage of milk, and improve milk pumping efficiency.

[0054] Furthermore, the arc-shaped design and even suction distribution can reduce local pressure on the nipple, lowering the risk of nipple damage or pain, especially for mothers with sensitive or easily injured nipples.

[0055] Furthermore, the arc-shaped airbag design can better adapt to breasts and nipples of different sizes and shapes, improving the versatility and applicability of the breast pump.

[0056] Furthermore, the simplified design with two air bladders makes the structure of the suction components simpler, making it easier for mothers to use and clean the breast pump, thus improving ease of use.

[0057] In other embodiments, multiple flexible airbags 41 units can be set up to achieve a wave-shaped squeezing sequence through differential inflation, thereby restoring the peristaltic stimulation of the infant's tongue.

[0058] In other embodiments, the flexible airbag 41 may adopt a wave-shaped structure design, so that its deformation process generates progressive pressure transmission. For example, the front flexible area deforms first to achieve priority stimulation of the nipple base, and the rear rigid support part delays the response to form a pressure gradient diffusion. A suitable design can be selected according to actual needs.

[0059] like Figures 1 to 9 As shown, the outer wall of each flexible airbag 41 in this embodiment is close to or abuts against the inner wall of the breast suction channel 21. By restricting the breast suction channel 21, it can be ensured that the flexible airbag 41 expands into the receiving space 42, ensuring the squeezing effect on the nipple.

[0060] like Figures 1 to 9 As shown, the suction component 4 in this embodiment also includes an assembly bracket 43. Each of the flexible airbags 41 is connected to the assembly bracket 43. The assembly bracket 43 has a through hole 431 in the middle that communicates with the accommodating space 42. The assembly bracket 43 has an air passage that communicates with the positive pressure air passage 11 and the flexible airbag 41 respectively, so that the positive pressure air generated by the air pump can enter the flexible airbag through the air passage and inflate it.

[0061] Specifically, the through hole 431 in the middle of the mounting bracket 43 communicates with the receiving space 42, and the through hole 431 allows the nipple to pass through and enter the receiving space 42.

[0062] Specifically, by connecting multiple flexible airbags 41 together using the mounting bracket 43, the airbags can be subjected to more even force, avoiding excessive deformation or damage to individual airbags.

[0063] Integrating the gas passage into the mounting bracket 43 allows for easy cleaning and maintenance, preventing gas passage blockage or contamination.

[0064] Furthermore, the presence of the mounting bracket 43 can enhance the structural stability of the suction assembly 4, improving its reliability and durability.

[0065] like Figures 1 to 9 As shown, the air passage in this embodiment includes an annular air passage 432 communicating with the positive pressure air passage 11 and multiple airbag air passages 433 communicating with the annular air passage 432. The airbag air passages 433 are correspondingly arranged with the flexible airbag 41.

[0066] Specifically, the positive pressure air path 11 can introduce the positive pressure air generated by the air pump into the annular air path 432, and the annular air path 432 then distributes the air to each flexible air bag 41 through multiple air bag air paths 433, causing the multiple flexible air bags 41 to inflate.

[0067] The design of the annular air passage 432 and the airbag air passage 433 ensures that each flexible airbag 41 is subjected to the same air pressure at the same time, generating uniform suction and avoiding excessive or insufficient local suction, thereby improving the comfort and safety of breastfeeding.

[0068] The design of the annular air passage 432 can reduce the airflow transmission distance, reduce airflow resistance, make the airflow smoother, and improve the response speed and suction output of the breast pump.

[0069] Preferably, integrating the annular air passage 432 and the airbag air passage 433 into the mounting bracket 43 can make the structure of the suction component 4 more compact, reduce space occupation, and facilitate integration and installation.

[0070] Furthermore, the design of the annular air passage 432 and the airbag air passage 433 allows for easy cleaning and maintenance, preventing air passage blockage or contamination and extending the lifespan of the breast pump.

[0071] Preferably, the assembly bracket 43 and the breast pump channel 21 can be connected by the following structures, such as: threaded connection:

[0072] The assembly bracket 43 and the breast suction channel 21 are provided with matching external and internal threads, which are screwed together by rotation to achieve a detachable connection.

[0073] Clip-on connection:

[0074] A snap-fit ​​structure, such as protrusions and grooves, is provided at the connection between the mounting bracket 43 and the breast pumping channel 21, and the connection is achieved through the interlocking of the snap-fits.

[0075] Interference connection:

[0076] The mounting bracket 43 and the breast pumping channel 21 are designed to be interference fit structures, and pressure is used to make the two fit tightly together to achieve connection.

[0077] Plug-in connection:

[0078] The connection between the mounting bracket 43 and the breast pump channel 21 is designed as a plug and socket, and the connection is achieved by plugging in.

[0079] Preferably, in this embodiment, at least one sealing ring 434 is provided between the assembly bracket 43 and the milk suction channel 21. The sealing ring enables an interference fit between the two and also improves the sealing performance between them. The sealing ring can achieve both connection and sealing performance, making the structure of the breast pump more compact.

[0080] Preferably, the front end of the breast suction channel 21 is provided with a positioning slot 211, which can abut against the side wall of the mounting bracket 43 to prevent the mounting bracket 43 from continuing to enter the breast suction channel 21 under the pressure of the breast. Through the cooperation of the mounting bracket 43 and the positioning slot 211, the positioning of the suction component 4 in the breast suction channel 21 is ensured, and its normal operation is ensured.

[0081] Preferably, in this embodiment, the mounting bracket 43 is provided with an inwardly recessed annular groove 435, and the annular groove 435 is provided with at least one air inlet 436 communicating with the annular air passage 432. Preferably, when the mounting bracket 43 is positioned and assembled into the breast milk suction channel 21, the annular groove 435 is located directly below the positive pressure air passage 11, and the positive pressure air passage 11 can provide gas to the annular air passage 432 through the annular groove 435 and the air inlet 436.

[0082] Preferably, since the annular groove 435 is an annular recessed structure, and under the action of the positioning clip 211, when the mounting bracket 43 is assembled into the breast milk suction channel 21, the annular groove 435 can be aligned with the position of the positive pressure air path 11. This design can improve the fault tolerance of the assembly, reduce the impact of assembly errors on gas transmission, and make the user not need to pay too much attention to the assembly position of the mounting bracket 43.

[0083] Preferably, the suction component 4 is made of plastic or silicone, and a suitable design can be selected according to actual needs.

[0084] like Figures 1 to 9 As shown, the air source device 5 in this embodiment includes an air pump 51, an exhaust assembly 52, and a positive pressure pipeline component 53. The positive pressure pipeline component 53 is provided with a first air delivery end 531, a first air inlet end 532, and a first exhaust end 533. The first air delivery end 531 is connected to the positive pressure air passage 11, and the first exhaust end 533 is connected to the exhaust assembly 52. ​​The air pump 51 is provided with a positive pressure air outlet end 511 connected to the first air inlet end 532.

[0085] Specifically, the air pump 51 delivers compressed gas to the positive pressure pipeline component 53 through the positive pressure outlet 511 and the first inlet 532. The positive pressure pipeline component 53 guides the gas to the first delivery end 531 and delivers the gas to the positive pressure air passage 11 through the first delivery end 531. The positive pressure air passage 11 transmits the gas to the mounting bracket 43 in the breast pumping channel 21 to provide positive pressure for the flexible airbag 41. This design can effectively establish and transmit positive pressure gas, realize the inflation of the flexible airbag 41, and realize the squeezing of the nipple.

[0086] During the breast pumping process, the gas inside the flexible airbag 41 needs to be released. The first exhaust end 533 of the positive pressure pipe component 53 is connected to the exhaust component 52, which can guide the gas inside the flexible airbag 41 to the exhaust component 52 for release.

[0087] Preferably, the exhaust assembly 52 can be a control element such as an exhaust valve or a solenoid valve. By controlling the opening and closing of the exhaust assembly 52, the air pressure inside the flexible airbag 41 can be adjusted, thereby adjusting the deformation of the flexible airbag 41. This design allows the flexible airbag 41 to deform in a regular manner, ensuring the suction effect of the suction assembly.

[0088] Furthermore, this design can improve the compactness and reliability of the air circuit, reduce the risk of gas leakage, and also facilitate the assembly and maintenance of the breast pump.

[0089] The air source device 5 is designed as an independent module, which can be easily assembled, disassembled and replaced. When the air pump 51, exhaust component 52 or positive pressure pipeline component 53 malfunctions or needs maintenance, the air source device 5 can be handled separately without disassembling the entire breast pump. This design improves the maintainability and serviceability of the breast pump, extends the service life of the product, and also facilitates the user's daily maintenance and cleaning.

[0090] like Figures 1 to 9 As shown, the exhaust assembly 52 of this embodiment includes a first solenoid valve 521 and a pressure detection element 522. The pressure detection element 522 is electrically connected to the first solenoid valve 521 and the air pump 51 respectively. When the pressure detection element 522 detects that the air pressure in the positive pressure pipeline component 53 reaches a predetermined threshold, the pressure detection element 522 can control the inflation flow rate of the air pump 51 and control the first solenoid valve 521 to exhaust, so that the suction assembly 4 returns to normal, and the flexible airbag 41 deforms regularly and repeatedly, thereby realizing the suction function.

[0091] Specifically, the air pressure detection element 522 monitors the air pressure inside the positive pressure pipeline component 53 in real time. When the air pressure reaches or exceeds the preset threshold, the air pressure detection element 522 will send a signal. After receiving the signal that the air pressure exceeds the threshold, the air pressure detection element 522 adjusts the inflation flow of the air pump 51 to reduce or stop inflation in order to avoid over-inflation. At the same time, the air pressure detection element 522 controls the first solenoid valve 521 to open and perform an exhaust operation to reduce the pressure inside the positive pressure pipeline component 53, so that the flexible airbag 41 gradually returns to its original shape.

[0092] By detecting air pressure in real time and automatically adjusting the air pump's inflation flow, the pressure inside the flexible airbag 41 is always maintained within the range most suitable for sucking, which helps improve breast pumping efficiency and user comfort.

[0093] Furthermore, the automatic control system prevents damage or shortened lifespan of the airbags due to overinflation, increasing the safety and durability of the equipment.

[0094] Furthermore, by controlling the inflation of the air pump and the deflation of the first solenoid valve, the flexible airbag 41 can deform regularly and repeatedly, more closely mimicking the rhythm of natural breastfeeding.

[0095] Preferably, the air pressure detection element 522 can be a structure such as an air pressure sensor or a pressure switch, and a suitable design can be selected according to actual needs.

[0096] like Figures 1 to 9 As shown, the milk bowl 1 in this embodiment is provided with a negative pressure chamber 12 and a negative pressure air passage 13. The milk suction channel 21 is located in the negative pressure chamber 12. The milk suction channel 21 is provided with a deformable structure 22. The air source device 5 also includes an air suction component 54 and a negative pressure pipe component 55. The negative pressure pipe component 55 is provided with a first air suction end 551, a second air suction end 552 and a second air inlet end 553. The first air suction end 551 is connected to the negative pressure air passage 13, and the second air inlet end 553 is connected to the air suction component 54. The air pump 51 is provided with a negative pressure air suction end 512 connected to the second air suction end 552. When the negative pressure chamber 12 is made to form a negative pressure under the action of the air pump 51, the deformable structure 22 can deform and expand to realize the milk suction channel 21 to suck milk.

[0097] Specifically, the air pump 51 is connected to the second air intake end 552 of the negative pressure pipeline component 55 through the negative pressure intake end 512, thereby establishing a connection with the negative pressure chamber 12. When the air pump 51 is working, it draws out the air in the negative pressure chamber 12 and forms a negative pressure environment in the negative pressure chamber 12.

[0098] Under the action of negative pressure, the deformable structure 22 located in the milk suction channel 21 deforms and expands. This expansion increases the volume of the milk suction channel 21 and generates suction. The negative pressure in the milk suction channel 21 draws milk from the breast into the milk bowl 1.

[0099] Air is drawn into the negative pressure air passage 13 by the suction assembly 54 to restore the air pressure in the milk suction channel 21, causing the deformable structure 22 to contract and return to its original shape.

[0100] With the above design, the expansion and contraction of the deformable structure 22 under the action of the air pump 51 simulates the changes in the oral cavity when an infant sucks, making the breastfeeding process closer to the feeling of natural breastfeeding and reducing stimulation and discomfort to the breast.

[0101] Furthermore, the establishment of a negative pressure environment and the expansion of the deformable structure enhance the suction of the milk-suction channel 21, enabling it to more effectively draw milk from the breast and improve milk-suction efficiency.

[0102] Specifically, the air pump 51 uses a positive pressure air path to enable the suction of the suction component and a negative pressure air path to enable the milk suction function of the milk suction channel 21. The two work together to promote smooth milk suction.

[0103] Preferably, the intake component 54 is a solenoid valve structure, and a suitable design can be selected according to actual needs.

[0104] Preferably, the deformation structure 22 can be a suction bowl located at the end of the breast pumping channel 21, or a deformation strip located on the outside of the breast pumping channel 21 that can drive the breast pumping channel 21 to deform. A suitable design can be selected according to actual needs.

[0105] like Figures 1 to 9 As shown, the breast pump main unit 3 of this embodiment is also provided with a control component 6 and a power supply component 7. The power supply component 7 includes a power supply battery 71 disposed in the breast pump main unit 3 and a charging port 72 disposed on one side of the breast pump main unit 3.

[0106] Specifically, the control component 6 is responsible for controlling and coordinating the various components of the breast pump, including the air pump 51, solenoid valve, pressure sensor, etc. It can adjust the rhythm, intensity and time of breast pumping according to the preset program or user input to meet the needs of different mothers.

[0107] Preferably, the control component 6 is typically composed of components such as a microprocessor, a memory, and a power management circuit. The microprocessor is responsible for running the control program, the memory is used to store the program and data, and the power management circuit is responsible for managing the power supply battery 71.

[0108] With the control component 6, the breast pump can be intelligently controlled, providing multiple pumping modes and parameter adjustments to meet the needs of different mothers. At the same time, the control component 6 can also realize the fault detection and protection functions of the breast pump, improving the safety and reliability of the breast pump.

[0109] Preferably, the power supply battery 71 is the power source of the breast pump, providing electrical energy to all components of the breast pump. Its capacity and type directly affect the battery life and performance of the breast pump.

[0110] By placing the power supply battery 71 inside the breast pump main unit 3, the appearance of the breast pump can be made simpler, and the battery replacement and maintenance can be made easier.

[0111] Preferably, the charging port 72 provides an interface for charging the power supply battery 71, allowing the breast pump to be charged via an external power source (such as an adapter).

[0112] The charging port 72 is located on one side of the breast pump main unit 3, which makes it easy for users to plug and unplug the charging cable without affecting the normal use of the breast pump.

[0113] The charging port 72 typically uses a standard USB or DC interface, making it convenient for users to charge the breast pump with a universal charger.
