Abstract
Description
Technical Field
[0001] This invention belongs to the field of nursing equipment technology, specifically referring to a wearable breast pump that can be heated. Background Technology
[0002] As a key nursing device for breastfeeding women, the core function of a breast pump is to help women safely and efficiently express and store breast milk to meet feeding needs in scenarios such as breastfeeding at work, excess milk, or separation of mother and baby. With the upgrading of maternal and infant care concepts, breast pumps with heating and massage functions have gradually become the mainstream in the market. By applying heat and physical massage to the breasts, they can effectively promote blood circulation in the breasts, relieve breast spasms, and unclog milk ducts, thereby improving lactation efficiency and breastfeeding comfort.
[0003] In the prior art, such as Chinese Patent No. CN121648377A, a heated massage lactation-inducing breast pump is disclosed, which includes a breast pump body, a shell and a breast pump shield. The breast pump shield is equipped with a nipple heating component (graphene heating film) and a breast peripheral heating component (carbon fiber heating wire). It also has a massage structure for massaging the breast. Through the synergistic effect of the heating structure and the massage structure, the breast pump achieves precise heating care and multi-dimensional lactation-inducing massage for the breast, which significantly improves the efficiency of breast pumping.
[0004] However, in this technical solution, both the heating diaphragm and the heating wire are electrically connected to the control panel via wires. This wired power supply method brings many inconveniences in actual use: on the one hand, the wire connection makes it difficult to disassemble and clean the breast pump shield, and users cannot thoroughly clean the breast pump shield that is in direct contact with the breast, which can easily lead to breast milk residue and bacterial growth; on the other hand, during frequent disassembly and installation, the wire connection terminals are prone to wear, poor contact, or even short circuits due to repeated plugging and unplugging, affecting the service life and safety of the equipment.
[0005] To address the aforementioned issues, some existing technologies attempt to improve the power supply structure of breast pumps. For example, Chinese patent CN224193834U discloses a breast pump with a heating component connection structure. This design involves installing a heating component on the breast shield, which is electrically connected to the main unit via connecting terminals. The main unit has mating holes for the connecting terminals to insert into, enabling a detachable electrical connection. However, this solution still relies on physically contacting conductive terminals. Precise alignment between the connecting terminals and the mating holes is required, and the contact points are susceptible to oxidation and corrosion when exposed to a humid environment for extended periods, affecting conductivity reliability.
[0006] It is evident that there is an urgent need for a heating and power supply solution that enables breast pump shields to be completely independent and without exposed wires. This would allow breast pump shields that come into direct contact with the breasts to be easily removed from the main unit for thorough cleaning and sterilization, while avoiding problems such as cleaning difficulties, poor contact, and safety hazards caused by the presence of wires or conductive contacts. Summary of the Invention
[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a completely independent, non-exposed wire, easy-to-assemble and disassemble, and thoroughly cleanable wearable breast pump.
[0008] The objective of this invention can be achieved through the following technical solutions: A wearable, heatable breast pump includes a main body containing a battery, a breast pump, and a milk storage chamber. The pump further includes a support frame, a wireless power receiving unit, a heating diaphragm, and a speaker cover. The wireless power receiving unit and the heating diaphragm are both mounted on the support frame. The heating diaphragm is located on the lower side of the support frame and is electrically connected to the wireless power receiving unit. The speaker cover encloses the support frame, the wireless power receiving unit, and the heating diaphragm. A wireless power transmitting unit that cooperates with the wireless power receiving unit is located within the main body. Both the wireless power transmitting unit and the breast pump are electrically connected to the battery.
[0009] This wearable breast pump with heating function integrates a wireless power receiving unit and a heating diaphragm within a speaker cover. A wireless power transmitting unit within the main body works in conjunction with the wireless receiving unit to wirelessly power the heating diaphragm. This ensures that the breast pump cover, consisting of the support frame, wireless receiving unit, heating diaphragm, and speaker cover, is completely independent of the main body, without any exposed wires or interfaces. This allows for easy disassembly and cleaning of the entire breast pump cover, preventing milk or water stains at the electrical interface from affecting power transmission. The structure is simpler and more stable. The support frame design effectively supports the speaker cover, wireless receiving unit, and heating diaphragm, preventing significant deformation of the speaker cover at the connection point. This avoids poor contact between the wireless receiving unit and the heating diaphragm due to deformation, or damage to the heating diaphragm due to excessive deformation, thus extending the lifespan of the wearable breast pump.
[0010] In the aforementioned wearable heated breast pump, the front of the lower side of the support frame is provided with a first groove and a second groove that are connected. The wireless power transmission and receiving unit is located in the first groove, and the heating diaphragm is located in the second groove. Heating diaphragms are provided on both the left and right sides of the wireless power transmission and receiving unit. The heating diaphragms are elongated and extend from the front of the support frame to the rear of the support frame.
[0011] The design of the first and second grooves on the aforementioned support frame enables the fixing of the wireless power transmission receiving unit and the heating film without affecting the function of the heating film. This prevents the wireless power transmission receiving unit and the heating film from shifting or undergoing significant deformation during use and cleaning, which helps to improve the overall structural strength and stability of the breast pump.
[0012] In the aforementioned wearable heated breast pump, a partition is provided inside the main body, dividing the main body into a milk storage chamber and an installation chamber. An annular sealing strip is provided on the outer peripheral wall of the partition. The middle part of the partition is bent upward and protrudes to form a negative pressure groove on the lower side of the partition. The upper end of the horn cover extends into the negative pressure groove. A milk outlet communicating with the milk storage chamber is provided on the negative pressure groove. A milk inlet communicating with the negative pressure groove is provided at the rear end of the horn cover. A sealing cover plate capable of sealing the milk outlet is rotatably connected to the outside of the milk outlet. An outwardly protruding sealing ring is formed on the outer peripheral wall of the middle part of the horn cover. The sealing ring can abut against the lower side of the partition around the negative pressure groove and form a seal. The horn cover and the negative pressure groove together form the negative pressure chamber, which is connected to the breast pump.
[0013] The design of the aforementioned partition ensures the formation of a sealed milk storage chamber, ensuring that the expressed milk is clean and safe. The design of the negative pressure groove, milk outlet, and sealing cover forms a negative pressure chamber. The milk pump draws air into the negative pressure chamber to create negative pressure, thereby stretching and deforming the upper end of the bell cover to draw milk out of the breast.
[0014] In the aforementioned heatable wearable breast pump, the support frame includes a trumpet-shaped support portion and a ring-shaped connecting portion. The lower end of the connecting portion is fixedly connected to the upper end of the support portion. The trumpet cover includes a contact portion and an elastic portion. The contact portion can wrap around the inner and outer sides of the support portion. The upper edge of the outer side wall of the contact portion fits against the lower edge of the connecting portion. The outer side of the inner side wall of the contact portion fits against the inner side of the connecting portion. The upper edge of the contact portion protrudes outward to form the sealing ring. The lower edge of the elastic portion is fixedly connected to the upper edge of the contact portion.
[0015] During the production of this breast pump, the wireless power receiving unit and heating diaphragm are first fixed to the lower side of the support frame. Then, the aforementioned horn cover is directly formed on the outside of the support frame, thereby ensuring the sealing and fixation of the horn cover with the support frame and completely enclosing the wireless power receiving unit and heating diaphragm. The structure of the support frame combined with the structure of the horn cover can ensure the overall structural strength of the breast pump, ensure that the horn cover in contact with the breast is not easily deformed, and at the same time, it is easy to disassemble and thoroughly clean.
[0016] In the aforementioned wearable heated breast pump, the main body includes a main cover plate, a partition plate, an upper mounting plate, and a lower mounting plate. The upper and lower mounting plates are detachably fixed and together form an installation cavity. The partition plate and the main cover plate together form a milk storage cavity. A sealing strip is disposed between the partition plate and the main cover plate. The main cover plate is detachably connected to the upper mounting plate. A milk outlet hole is provided at the front of the main cover plate. The front end of the sealing strip is formed with a sealing plug that can extend out of the main cover plate and seal the milk outlet hole.
[0017] The structure of the main body allows for easy disassembly of the main cover and breast shield, enabling thorough cleaning of all parts of the wearable breast pump that come into contact with breast milk. The structure is simple, easy to assemble and disassemble, and has a high level of safety.
[0018] In the aforementioned wearable heated breast pump, a positioning ring protruding upward is formed in the middle of the lower mounting plate, a through hole that mates with the positioning ring is provided on the upper mounting plate, the outer wall of the connecting part is fitted with the inner wall of the positioning ring, an annular limiting groove is provided on the outer peripheral wall of the connecting part, a guide groove for connecting the limiting groove and the upper side of the connecting part is provided on the outer peripheral wall of the connecting part, and a limiting top post that can extend into the limiting groove is provided on the positioning ring, and the limiting top post can be disengaged from the limiting groove by the guide.
[0019] The limiting groove and guide groove on the aforementioned connecting part, together with the limiting top post on the positioning ring, enable axial positioning and disengagement of the breast pump. When it is necessary to remove the breast pump, rotate the breast pump until the limiting top post aligns with the guide groove, and then pull the breast pump downwards. In normal operation, the limiting top post and guide groove are offset. Preferably, the limiting top post and guide groove are offset by approximately 90 degrees.
[0020] In the aforementioned wearable heated breast pump, the partition protrudes upward to form a buffer groove. An upper mounting plate is provided inside the main body, located below the partition. The upper mounting plate and the buffer groove of the partition together form a buffer cavity. An elastic cylinder plate is provided inside the buffer cavity. The edge of the elastic cylinder plate is fixed and sealed to the inner wall of the buffer cavity. The buffer groove communicates with the negative pressure groove, and the connection hole is located above the elastic cylinder plate. The breast pump communicates with the buffer cavity through the upper mounting plate, and the connection point is located below the elastic cylinder plate.
[0021] When this wearable breast pump is in operation, the pump creates negative pressure in the buffer chamber below the elastic cylinder plate. This negative pressure causes the elastic cylinder plate to deform downwards, creating negative pressure in the buffer chamber above it. This negative pressure then flows through the connecting hole, creating negative pressure within the negative pressure chamber, which in turn causes the upper part of the bell-shaped cover to deform, creating negative pressure within the milk suction chamber formed by the breast and the bell-shaped cover, thus achieving the milk suction function. When the pump stops working, the pressure in the buffer chamber below the elastic cylinder plate returns to normal, and the elastic cylinder plate returns to normal, creating positive pressure in the buffer chamber above it. This positive pressure then flows through the connecting hole, creating positive pressure within the negative pressure chamber, causing the sealing cover to open, allowing the milk in the negative pressure chamber to enter the milk storage chamber through the milk outlet, thus completing the entire milk suction process. This wearable breast pump, by incorporating a buffer groove and an elastic cylinder plate, makes the pressure curve of the negative pressure generated during milk suction smoother, reducing user discomfort and improving the comfort of the milk suction process.
[0022] In the aforementioned wearable heated breast pump, the elastic cylinder plate is hemispherical, and an outwardly protruding annular positioning ring is formed at the lower end of the elastic cylinder plate. A reinforcing ring is embedded in the annular positioning ring. A positioning groove for accommodating the annular positioning ring is formed at the connection between the partition plate and the upper mounting plate. The annular positioning ring is sealed to the groove wall of the positioning groove and the upper side of the lower mounting plate. A spiral easy-break groove is provided on the outer side wall of the elastic cylinder plate.
[0023] The aforementioned annular positioning ring design achieves the fixation and sealing of the elastic cylinder plate; the hemispherical elastic cylinder plate and the easily broken groove design make the deformation and recovery of the elastic cylinder plate after air pressure changes more regular, thereby making the pressure change more gradual and stable, and improving the comfort of the breastfeeding process.
[0024] In the aforementioned wearable heated breast pump, the buffer groove is formed on the front of the partition, the breast pump is located at the rear of the mounting cavity, the battery is located on the left and right sides of the mounting cavity, the rear of the main body is provided with a charging interface, the front of the mounting cavity is provided with a circuit board, the left and right sides of the front of the main body are provided with control buttons electrically connected to the circuit board, and the wireless power transmission unit and the breast pump are both electrically connected to the circuit board.
[0025] This wearable breast pump is used vertically with the breast shield close to the breast and the front end of the pump facing upwards. The design of the pump, battery, charging port, control button and circuit board makes the center of gravity of this wearable breast pump more balanced, which helps to improve the comfort during use.
[0026] Compared with the prior art, the technical effects of the present invention are as follows: 1. In this invention, the support frame and the horn cover are molded as an integral structure. The support frame provides stable structural support, ensuring that the breast shield is not easily collapsed or deformed under negative pressure, thereby ensuring the stability of the negative pressure cavity volume and facilitating the smooth output of the suction curve. The horn cover completely wraps around the lower end of the support frame, making the part in contact with the breast a soft material, which improves wearing comfort. The horn cover is made of flexible materials such as silicone, rubber, or thermoplastic elastomer (TPE). 2. The design of the support frame in this invention can also support the wireless power transmission and receiving unit and the heating diaphragm, which can effectively prevent the speaker cover at the connection with the support frame from being deformed. This avoids poor contact between the wireless power transmission and receiving unit and the heating diaphragm or damage to the heating diaphragm due to large deformation caused by such deformation, which helps to improve the service life of this wearable breast pump. 3. This invention integrates the wireless power transmission and receiving unit and the heating diaphragm within the speaker cover. Then, through the cooperation of the wireless power transmission and receiving unit located within the main body, wireless power transmission to the heating diaphragm is achieved. This ensures that the breast pump, composed of the support frame, wireless power transmission and receiving unit, heating diaphragm, and speaker cover, can be completely independent of the main body without any wires or exposed interfaces. This facilitates the complete disassembly and cleaning of the breast pump and prevents milk or water stains from remaining at the electrical interface during use or after cleaning, thus avoiding interference with normal power transmission. The structure is simpler and more stable. Attached Figure Description

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0038] This wearable, heatable breast pump includes a main body 4, which houses a battery 44, a breast pump 43, and a milk storage chamber 41. It also includes a support frame 1, a wireless power receiving unit 31, a heating diaphragm 32, and a speaker cover 2. The wireless power receiving unit 31 and the heating diaphragm 32 are both mounted on the support frame 1. The heating diaphragm 32 is located on the lower side of the support frame 1 and is electrically connected to the wireless power receiving unit 31. The speaker cover 2 encloses the support frame 1, the wireless power receiving unit 31, and the heating diaphragm 32. A wireless power transmitting unit 33, which cooperates with the wireless power receiving unit 31, is located inside the main body 4. Both the wireless power transmitting unit 33 and the breast pump 43 are electrically connected to the battery 44.
[0039] In this wearable heated breast pump, the support frame 1 and the horn cover 2 are molded as a single unit. The support frame 1 provides stable structural support, ensuring that the breast pump cover is not prone to collapse or deformation under negative pressure, thereby ensuring the stability of the negative pressure chamber volume and facilitating a smooth suction curve. The horn cover 2 completely covers the lower end of the support frame 1, making the part in contact with the breast a soft material, thus improving wearing comfort. The aforementioned horn cover 2 is made of flexible materials such as silicone, rubber, or thermoplastic elastomer (TPE). The design of the support frame 1 also supports the wireless power receiving unit 31 and the heating diaphragm 32, effectively preventing large deformation of the horn cover 2 at the connection point with the support frame 1. This avoids poor contact between the wireless power receiving unit 31 and the heating diaphragm 32 caused by such deformation, or damage to the heating diaphragm 32 due to large deformation, which helps to extend the service life of this wearable breast pump.
[0040] This wearable breast pump with heating function integrates a wireless power receiving unit 31 and a heating diaphragm 32 within a speaker cover 2. A wireless power transmitting unit 33, located within the main body 4, works in conjunction with the wireless power receiving unit 31 to wirelessly power the heating diaphragm 32. This ensures that the breast pump, composed of the support frame 1, wireless power receiving unit 31, heating diaphragm 32, and speaker cover 2, is completely independent of the main body 4 without any exposed wires or interfaces. This facilitates easy disassembly and cleaning of the entire breast pump, and also prevents milk or water stains from affecting power transmission at the electrical interface during use or after cleaning. The design is simpler and more stable.
[0041] Furthermore, the lower side of the support frame 1 is provided with a first groove 111 and a second groove 112 that are connected. The wireless power receiving unit 31 is disposed in the first groove 111, and the heating diaphragm 32 is disposed in the second groove 112. Heating diaphragms 32 are provided on both the left and right sides of the wireless power receiving unit 31. The heating diaphragms 32 are elongated and extend from the front to the rear of the support frame 1. The design of the first groove 111 and the second groove 112 on the support frame 1 can fix the wireless power receiving unit 31 and the heating diaphragm 32 without affecting the function of the heating diaphragm 32, thereby avoiding displacement or large deformation of the wireless power receiving unit 31 and the heating diaphragm 32 during use and cleaning, which is beneficial to improving the structural strength and stability of the overall breast pump.
[0042] like Figure 2As shown, a partition 5 is provided inside the main body 4, which divides the main body 4 into a milk storage chamber 41 and an installation chamber 42. An annular sealing strip 9 is provided on the outer peripheral wall of the partition 5. The middle part of the partition 5 is bent upward and protrudes to form a negative pressure groove 51 on the lower side of the partition 5. The upper end of the horn cover 2 extends into the negative pressure groove 51. A milk outlet 52 communicating with the milk storage chamber 41 is provided on the negative pressure groove 51. The rear end of the horn cover 2 is provided with... The milk inlet 221 is connected to the negative pressure groove 51. The outer side of the milk outlet 52 is rotatably connected to a sealing cover 53 that can seal the milk outlet 52. A sealing ring 211 protruding outward is formed on the outer peripheral wall of the middle part of the horn cover 2. The sealing ring 211 can abut against the lower side of the partition 5 around the negative pressure groove 51 and form a seal. The horn cover 2 and the negative pressure groove 51 together form the negative pressure chamber, which is connected to the milk pump 43.
[0043] like Figure 7-9 As shown, the support frame 1 includes a trumpet-shaped support part 11 and an annular connecting part 12. The lower end of the connecting part 12 is fixedly connected to the upper end of the support part 11. The trumpet cover 2 includes a contact part 21 and an elastic part 22. The contact part 21 can wrap the inner and outer sides of the support part 11. The upper edge of the outer side wall of the contact part 21 fits with the lower edge of the connecting part 12. The outer side of the inner side wall of the contact part 21 fits with the inner side of the connecting part 12. The upper edge of the contact part 21 protrudes outward to form the sealing protrusion ring 211. The lower edge of the elastic part 22 is fixedly connected to the upper edge of the contact part 21.
[0044] like Figure 1-5 As shown, the main body 4 includes a main cover plate 6, a partition plate 5, an upper mounting plate 7, and a lower mounting plate 8. The upper mounting plate 7 and the lower mounting plate 8 are detachably fixed and together form an installation cavity 42. The partition plate 5 and the main cover plate 6 together form a milk storage cavity 41. A sealing strip 9 is disposed between the partition plate 5 and the main cover plate 6. The main cover plate 6 is detachably connected to the upper mounting plate 7. The front part of the main cover plate 6 is provided with a milk outlet hole 61. The front end of the sealing strip 9 is formed with a sealing plug 91 that can extend out of the main cover plate 6 and seal the milk outlet hole 61. The middle part of the lower mounting plate 8... The upper mounting plate 7 has a through hole 71 that mates with the positioning ring 81. The outer wall of the connecting part 12 fits against the inner wall of the positioning ring 81. The outer peripheral wall of the connecting part 12 has an annular limiting groove 121. The outer peripheral wall of the connecting part 12 has a guide groove 122 for connecting the limiting groove 121 and the upper side of the connecting part 12. The positioning ring 81 has a limiting top post 82 that can extend into the limiting groove 121. The limiting top post 82 can be dislodged from the limiting groove 121 by the guide.
[0045] Furthermore, the partition 5 protrudes upward to form a buffer groove 54. An upper mounting plate 7 is provided inside the main body 4. The upper mounting plate 7 is located on the lower side of the partition 5. The upper mounting plate 7 and the buffer groove 54 of the partition 5 together form a buffer cavity 55. An elastic cylinder plate 56 is provided inside the buffer cavity 55. The edge of the elastic cylinder plate 56 is fixed and sealed to the inner wall of the buffer cavity 55. The buffer groove 54 is connected to the negative pressure groove 51 and the connection hole is located on the upper side of the elastic cylinder plate 56. The milk pump 43 is connected to the buffer cavity 55 through the upper mounting plate 7. The connection point is located on the lower side of the elastic cylinder plate 56.
[0046] This wearable breast pump features a negative pressure groove 51 and a buffer groove 54 on the lower side of the partition 5, with an elastic cylinder plate 56 installed within the buffer groove 54. The elastic cylinder plate 56 divides the buffer chamber 55 into a first chamber connected to the negative pressure chamber and a second chamber connected to the breast pump 43. When the breast pump 43 operates, a periodic negative pressure is generated in the second chamber. This negative pressure is buffered by the elastic cylinder plate 56 before being transmitted to the first chamber, and then to the negative pressure chamber. The elastic cylinder plate 56 absorbs and delays the suction peak using its own elastic deformation, transforming the stepped or pulsed suction directly generated by the breast pump 43 into a continuous and smooth negative pressure waveform. This makes the suction applied to the breast closer to the smooth and gradual negative pressure during natural breastfeeding, effectively avoiding the impact and pulling of sudden negative pressure on breast tissue, significantly reducing or even eliminating pain during breast pumping, and improving comfort and safety. When the milk pump 43 stops working, the pressure in the buffer chamber 55 (second chamber) on the lower side of the elastic cylinder plate 56 is restored. The elastic cylinder plate 56 will rise and form a positive pressure in the buffer chamber 55 (first chamber) on the upper side of the elastic cylinder plate 56. This positive pressure will form a positive pressure in the negative pressure chamber through the connecting hole, causing the sealing cover plate 53 to open, so that the milk in the negative pressure chamber can enter the milk storage chamber 41 through the milk outlet 52, thereby completing the entire milk pumping action.
[0047] Preferably, the elastic cylinder plate 56 is hemispherical, and an outwardly protruding annular positioning ring 561 is formed at the lower end of the elastic cylinder plate 56. A reinforcing ring 562 is embedded in the annular positioning ring 561. A positioning groove 57 for accommodating the annular positioning ring 561 is formed at the connection between the partition plate 5 and the upper mounting plate 7. The annular positioning ring 561 is sealed to the groove wall of the positioning groove 57 and the upper side of the lower mounting plate 8. A spiral easy-break groove 563 is provided on the outer side wall of the elastic cylinder plate 56.
[0048] This wearable breast pump employs a hemispherical structure with a spiral, easily foldable groove 563. This allows the elastic cylinder plate 56 to deform orderly along the path of the spiral groove when under pressure, avoiding suction fluctuations caused by irregular deformation. This results in a more uniform and smooth suction transmission. Simultaneously, the hemispherical structure has a larger deformation stroke and better resilience than a planar diaphragm, adapting to pressure variations at different pumping levels and improving the pump's adaptability to different users. Preferably, the central axis of the easily foldable groove 563 coincides with the central axis of the elastic cylinder plate 56. This structure ensures that the deformation of the elastic cylinder plate 56 is evenly distributed circumferentially under negative pressure, avoiding uneven suction transmission caused by eccentric deformation. This further guarantees the symmetry and smoothness of the suction waveform received by the negative pressure chamber, improving the consistency of force on different parts of the breast during pumping and enhancing user comfort. This wearable breast pump achieves rapid and precise positioning of the elastic cylinder plate 56 through the cooperation of the annular positioning ring 561 and the positioning groove 57, facilitating assembly and improving production efficiency. Simultaneously, this sealed and fixed connection structure ensures airtight isolation between the two sides of the elastic cylinder plate 56, preventing the negative pressure generated by the breast pump 43 from leaking directly into the buffer chamber 55 on the upper side of the elastic cylinder plate 56 without buffering. The design of the reinforcing ring 562 significantly improves the structural strength of the annular positioning ring 561, preventing deformation or loosening under long-term alternating negative pressure, thereby ensuring the long-term sealing reliability between the elastic cylinder plate 56 and the positioning groove 57, extending the product's service life, and ensuring the sustained stability of the buffering effect, thus guaranteeing the effectiveness of the buffering action.
[0049] In the aforementioned wearable heated breast pump, the buffer groove 54 is formed on the front of the partition 5, the breast pump 43 is disposed at the rear of the mounting cavity 42, the battery 44 is disposed on the left and right sides of the mounting cavity 42, the rear of the main body 4 is provided with a charging interface 46, the front of the mounting cavity 42 is provided with a circuit board 45, the left and right sides of the front of the main body 4 are provided with control buttons 83 electrically connected to the circuit board 45, and the wireless power transmission unit 33 and the breast pump 43 are both electrically connected to the circuit board 45.
[0050] This wearable breast pump is used vertically, with the breast shield close to the breast and the front of the pump facing upwards. Through the optimized spatial layout of the above-mentioned components, the internal structure of the entire breast pump is compact and the center of gravity is balanced, making it easy for users to wear and use. At the same time, the batteries 44 are symmetrically arranged on both sides, which effectively reduces the overall height of the device, making it more comfortable to wear and reducing the feeling of foreign objects. The design of front-mounted control buttons 83 and rear-mounted charging port 46 conforms to ergonomic operating habits and improves the user experience.
[0051] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection defined by the claims of the present invention.
