Description

[Technical Field] This application belongs to the field of maternal and infant products technology, specifically relating to a wearable breast pump. [Background Technology] Breast pumps are essential maternity and baby products for many breastfeeding women. They help mothers express and store breast milk, relieve engorgement, or provide breastfeeding for infants when separated from their babies. Traditional breast pumps typically consist of a main unit, a long tubing, a breast shield that contacts the breast, and a milk storage bottle. These pumps are bulky, require handheld use, and the tubing restricts the mother's freedom of movement, making them inconvenient to use. Therefore, wearable breast pumps have emerged on the market. However, the current wearable breast pump technology often uses a stacked layout of the main unit and milk storage components, which often results in inefficient use of internal space, leading to a still relatively large pump that is inconvenient for users to carry and use. [Utility Model Content] To address the problem that the internal space of wearable breast pumps cannot be effectively utilized in the prior art, this application provides a wearable breast pump.

[0004] This application is achieved through the following technical solution: A wearable breast pump includes a main unit, a milk storage bowl adapted to the main unit for collecting breast milk, and a connecting mechanism for detachably connecting the main unit and the milk storage bowl. The main unit is provided with a pump assembly for generating negative pressure and a power supply for powering the pump assembly. After the main unit and the milk storage bowl are connected through the connecting mechanism, the two are arranged vertically side by side. The main unit is located on the side closer to the user's body, while the milk storage bowl is located on the side farther away from the user's body.

[0006] As described above, in a wearable breast pump, the connecting mechanism includes an external thread on the connecting edge of the main unit and an internal thread on the corresponding edge of the milk storage bowl; or the connecting mechanism includes an external thread on the connecting edge of the milk storage bowl and an internal thread on the corresponding edge of the main unit, wherein the main unit and the milk storage bowl are connected by the internal thread and the external thread.

[0007] As described above, a wearable breast pump further includes a horn cover that passes through the main unit and snaps into the main unit. The horn cover has a first opening, the milk storage bowl has a second opening, and the main unit has a fourth opening. The first opening of the horn cover passes through the fourth opening of the main unit and extends to the second opening of the milk storage bowl. The first opening is sealed to the inner wall of the second opening.

[0008] As described above, a wearable breast pump also includes a suction bowl. The main unit is provided with a first receiving groove, and the milk storage bowl is provided with a second receiving groove. The main unit is connected to the milk storage bowl so that the first receiving groove and the second receiving groove cooperate to form a negative pressure chamber. The suction bowl is disposed in the negative pressure chamber, and the pump assembly is connected to the first receiving groove through an air tube.

[0009] As described above, a wearable breast pump includes a milk storage bowl comprising a lid and a bowl body sealed to the lid. The lid is provided with a nipple receiving compartment corresponding to the second opening. A milk suction channel is provided between the bottom of the nipple receiving compartment and the second receiving groove, and the second receiving groove is located below the milk suction channel.

[0010] As described above, in a wearable breast pump, the second receiving groove is provided with a third opening that communicates with the bowl body, and the third opening is provided with a one-way valve that allows breast milk to flow into the bowl body and prevents backflow.

[0011] As described above, a wearable breast pump further includes a snap-fit ​​mechanism for detachably connecting the speaker cover and the main unit. The snap-fit ​​mechanism includes a positioning ring on the main unit and a positioning groove on the speaker cover; or the snap-fit ​​mechanism includes a positioning ring on the speaker cover and a positioning groove on the main unit, wherein the positioning ring snaps into the positioning groove to connect the speaker cover and the main unit.

Detailed Implementation Methods

[0019] Please see Figures 1 to 10 A wearable breast pump includes a main unit 1, a milk storage bowl 2 adapted to the main unit 1 and used for collecting breast milk, and a connecting mechanism 3 for detachably connecting the main unit 1 and the milk storage bowl 2. The main unit 1 is provided with a pump assembly 11 for generating negative pressure and a power supply for supplying power to the pump assembly 11. After the main unit 1 and the milk storage bowl 2 are connected through the connecting mechanism 3, the two are arranged vertically side by side.

[0020] In this embodiment, by arranging the main unit 1 and the milk storage bowl 2 vertically side by side, the simple stacking pattern in the prior art is changed. This allows for more efficient use of every inch of space inside the breast pump, solving the problem that traditional layouts either result in excessive size to ensure milk storage capacity or sacrifice capacity for compactness. Ultimately, while achieving a thinner and lighter product, improved wearing comfort and concealment, it provides users with a larger milk storage capacity. During operation, after the user assembles and wears the main unit 1 and milk storage bowl 2 via the connecting mechanism 3, the built-in power is activated, and the pump assembly 11 immediately starts working to generate negative pressure. This negative pressure acts on the user's breast through the milk suction channel, drawing out milk and collecting it in the milk storage bowl 2. To further reduce the internal space of the main unit 1, as a preferred embodiment of this solution rather than a limitation, the pump assembly 11 specifically adopts a pump-valve integrated module that integrates the pump body and the solenoid valve, omitting the separate solenoid valve. This highly integrated design solves the problems of large space occupation and complex air circuits of separate components, thereby freeing up more space for the main unit 1 to accommodate a larger capacity battery or a more powerful motor, resulting in additional beneficial effects such as improved range or efficiency.

[0021] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the host 1 is located on the side closer to the user's body, and the milk storage bowl 2 is located on the side farther away from the user's body.

[0022] In this embodiment, the main unit 1, which includes heavier components such as the motor and battery, is placed on the side closer to the body, while the milk storage bowl 2 is placed on the outside. The advantage of this layout is that it not only solves the problem of existing products being unable to balance size and capacity by improving space utilization, but more importantly, it brings the center of gravity of the product as close to the body as possible, thereby greatly enhancing the stability and comfort of wearing it and effectively avoiding the feeling of being top-heavy and sinking caused by the increase in milk storage.

[0023] Furthermore, as a preferred embodiment of this solution and not a limitation, the cross-sections of the host 1 and the milk storage bowl 2 are circular.

[0024] In this embodiment, the circular mating surface can perfectly cooperate with sealing rings, such as O-rings, to form a uniform, seamless sealing pressure, fundamentally solving the problem of poor sealing at the edges of irregularly shaped structures, which easily leads to air and milk leakage, resulting in extremely high connection reliability. Secondly, the rounded, regular contours eliminate complex curves and sharp angles, making it more universally compatible with the body curves of different users, avoiding localized pressure and significantly improving wearing comfort. Combined with the vertically parallel layout of both, the internal space utilization is further optimized, resolving the contradiction between volume and capacity.

[0025] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting mechanism 3 includes an elastic element 31, a bead 32 disposed on the main unit 1, and a groove 33 disposed on the milk storage bowl 2 and corresponding to the bead 32, or a bead 32 disposed on the milk storage bowl 2 and a groove 33 disposed on the main unit 1 and corresponding to the bead 32, wherein the elastic element 31 drives the bead 32 to engage with the groove 33 to connect the main unit 1 and the milk storage bowl 2.

[0026] In this embodiment, the connecting mechanism 3, through the ingenious cooperation of the elastic element 31, the bead 32, and the groove 33, provides an excellent assembly experience, solving the problems of vague connection feel and user uncertainty about whether the installation is in place in existing products. When the user aligns the main unit 1 with the milk storage bowl 2 and presses it, the elastic element 31 will drive the bead 32 to automatically engage in the groove 33, producing a crisp "click" sound and a clear engagement feel, providing the user with clear auditory and tactile feedback, ensuring a fast, stable, and reliable connection. In another embodiment, the connecting mechanism 3 can use a snap-fit ​​connection method, setting matching protrusions and grooves at the interface between the main unit and the milk storage bowl, or setting one or more elastic arms with barbs on one component, and setting a corresponding slot on another component, so that pressing deforms the elastic arm and snaps it into the slot to achieve fixation. Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a horn cover 4 that passes through and is snapped into the host 1. The horn cover 4 has a first opening 41, the milk storage bowl 2 has a second opening 21, and the host 1 has a fourth opening 15. The first opening 41 of the horn cover 4 passes through the fourth opening 15 of the host 1 and extends to the second opening 21 of the milk storage bowl 2. The first opening 41 is sealed to the inner wall of the second opening 21.

[0027] In this embodiment, by allowing the horn cover 4 to pass through the main unit 1 and be directly and sealed to the second opening 21 of the milk storage bowl 2, a completely closed milk suction channel is formed. This channel strictly confines the entire process of breast milk from suction to storage within the horn cover 4 and the milk storage bowl 2, completely eliminating any possibility of breast milk coming into contact with the interior of the main unit 1, which contains electronic components. This solves the technical problems of hygiene dead spots, cleaning difficulties, and potential cross-contamination caused by milk flowing through the interior of the main unit in traditional integrated breast pumps. Users only need to clean two components: the horn cover and the milk storage bowl, greatly simplifying cleaning and maintenance and ensuring the cleanliness and safety of breast milk.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, the host 1 is provided with a positioning ring 12, and the speaker cover 4 is provided with a positioning groove 42; or the snap-fit ​​mechanism 6 includes a positioning ring 12 provided on the speaker cover 4, and the host 1 is provided with a positioning groove 42, the positioning ring 12 snaps into the positioning groove 42 to connect the speaker cover 4 and the host 1, the host 1 is provided with a limiting protrusion 13, and the speaker cover 4 is provided with a limiting notch 43 for the limiting protrusion 13 to snap into to limit the rotation of the speaker cover 4 relative to the host 1.

[0029] In this embodiment, a dual fastening structure with both axial locking and circumferential positioning functions is constructed through the engagement of the positioning ring 12 and the positioning groove 42, and the cooperation of the limiting protrusion 13 and the limiting notch 43. First, the cooperation of the limiting protrusion and the notch plays a precise guiding and "foolproof" role, ensuring that the user places the speaker cover 4 at the only correct rotation angle when installing it, thereby ensuring the precise alignment of the internal air passage and milk passage, and solving the problem of sealing failure or functional abnormality that may be caused by random rotation during installation. Based on this precise positioning, the positioning ring snapping into the positioning groove provides a crisp "click" sound and a firm axial locking force, providing the user with clear feedback of successful installation and eliminating the risk of accidental detachment during use.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a suction bowl 5. The main unit 1 is provided with a first receiving groove 14, and the milk storage bowl 2 is provided with a second receiving groove 22. The main unit 1 is connected to the milk storage bowl 2 so that the first receiving groove 14 and the second receiving groove 22 cooperate to form a negative pressure chamber. The suction bowl 5 is disposed in the negative pressure chamber, and the pump assembly 11 is connected to the first receiving groove 14 through an air pipe.

[0031] In this embodiment, by designing the negative pressure chamber as a combination of the first receiving groove 14 on the main unit 1 and the second receiving groove 22 on the milk storage bowl 2, and placing the suction bowl 5 within it, a very high degree of structural integration and space utilization is achieved. This solves the problem of traditional breast pumps requiring a complete and independent negative pressure system inside the main unit, resulting in a bulky main unit. By utilizing the space on one side of the milk storage bowl, it provides sufficient space for the movement of the suction bowl 5 without increasing the product's thickness, allowing the entire product to be made thinner and more integrated. Its working principle is as follows: When the pump assembly 11 is activated, air is extracted from the sealed negative pressure chamber, which is composed of the first receiving groove 14 and the second receiving groove 22, through the air tube. The reduced air pressure inside the chamber causes the elastic suction bowl 5 placed within to deform. This deformation is transmitted to the speaker grille, thereby generating negative pressure on the user's breast for milk extraction.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the milk storage bowl 2 includes a lid 23 and a bowl 24 sealed to the lid 23. The lid 23 is provided with a nipple receiving chamber 231 corresponding to the second opening 21. A milk suction channel 232 is provided between the bottom of the nipple receiving chamber 231 and the second receiving groove 22. The second receiving groove 22 is located below the milk suction channel 232.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the second receiving groove 22 is provided with a surrounding wall 223, and the suction bowl 5 is provided with a slot 51 for fitting onto the outside of the surrounding wall 223. The slot 51 on the suction bowl 5 is fitted onto the outside of the surrounding wall 223 so that the suction bowl 5 and the second receiving groove 22 are sealed together.

[0034] In this embodiment, by designing the milk storage bowl 2 as a combination of a lid 23 and a bowl 24, the milk suction channel 232 is positioned above the second receiving groove 22 used to apply negative pressure. The suction bowl 5 acts as a diaphragm to achieve gas-liquid separation. This solves the problem in traditional breast pumps where milk backflow and contamination of the main pump components are easily caused by the close proximity or connection between the air and milk paths. It ensures the absolute cleanliness of the breast milk and protects the core components from damage. Its working principle is as follows: the negative pressure generated by the pump assembly acts on the suction bowl below through the main unit and the second receiving groove 22, causing it to deform. This negative pressure is transmitted upwards to the milk suction channel 232 and the nipple receiving chamber 231, sucking out the breast milk. Under the influence of gravity, the sucked-out breast milk flows along the milk suction channel 232 and eventually enters the bowl 24 through a one-way valve. The airflow used to generate suction is drawn away from the first receiving groove. The two paths do not interfere with each other, thus achieving complete gas-liquid separation.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the second receiving groove 22 is provided with a third opening 221 communicating with the bowl body 24, and the third opening 221 is provided with a one-way valve 222 for allowing breast milk to flow into the bowl body 24 and preventing backflow.

[0036] In this embodiment, a one-way valve 222 is added at the third opening 221 of the connecting bowl 24, providing a crucial physical barrier for the collected breast milk. This solves the problem of milk splashing or flowing back into the suction area within the bowl 24 when the user moves, bends over, or shakes while wearing the breast pump, thus achieving true "splash prevention" and greatly enhancing the product's sealing and reliability. Its working principle is as follows: the negative pressure generated by the pump assembly deforms the suction bowl and acts on the milk extraction channel, drawing out the breast milk; when the breast milk flows through the channel to the third opening 221, its flow pressure pushes open the one-way valve 222, allowing it to flow smoothly into the bowl 24 for storage; once the milk enters the bowl 24, the one-way valve 222 immediately closes, completely blocking its backflow path and ensuring the stability and hygiene of the suction system. The one-way valve 222 specifically adopts a duckbill valve made of silicone material. This valve body solves the problems of easy jamming and poor sealing of traditional mechanical valve plates. It can work with extremely low opening pressure and in a silent manner, producing the additional effects of improved sealing performance and quiet operation.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the speaker cover 4 integrates functional elements such as heating elements, vibration elements, or biomimetic suction airbags.

[0038] In this embodiment, by integrating functional elements such as heating, vibration, or bionic suction airbags into the speaker cover 4, the breast pump is upgraded from a simple negative pressure milk-expressing tool into an intelligent breastfeeding aid capable of actively intervening in and optimizing the lactation process. This addresses the technological gap of traditional breast pumps, which can only passively express milk and are ineffective at common breastfeeding problems such as lactation induction and milk duct unblocking. Its working principle is as follows: while the pump assembly inside the main unit 1 generates negative pressure suction, the user can replace the speaker cover with different integrated functions to achieve different effects. For example, if the heating element uses a flexible PI heating film, it generates constant heat after being powered on, which is applied to the breast through the speaker cover 4 to promote the dilation of milk ducts and accelerate milk flow; the vibration element, such as an eccentric rotor vibration motor, simulates human hand massage through high-frequency micro-vibration to help clear lumps and blockages; and the bionic suction airbag, through rhythmic inflation and deflation, simulates the sucking and squeezing movements of an infant's mouth on the areola, more effectively stimulating milk let-down. These functions work synergistically with the main suction to achieve a more efficient and comfortable lactation experience.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the cover 23 is provided with a third receiving groove 233 for the pump assembly 11 to be installed, and the third receiving groove 233 is located above the milk suction channel 232.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the bowl 24 is made of a transparent material. By making the bowl 24 of a transparent material, the user is provided with real-time visual feedback on the lactation status and milk volume, fundamentally solving the "blind suction" problem of traditional opaque breast pumps. Users can intuitively confirm whether the milk is flowing smoothly and the current collected volume without interrupting lactation or disassembling the device, alleviating potential user anxiety and facilitating accurate judgment of when to empty the milk storage bowl, avoiding the risk of spillage. Its working principle is as follows: the negative pressure generated by the pump assembly draws out breast milk, which drips into and is stored in the bowl 24 after passing through the milk suction channel. The entire collection process and the accumulated milk volume can be clearly observed by the user through the transparent bowl 24. The transparent material uses materials such as polyphenylene sulfone (PPSU) or modified PCTG, which provides high clarity while also possessing excellent impact resistance and chemical resistance, resulting in the additional beneficial effects of improving product safety and service life.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, a magnifying lens 241 is provided at the top of the bowl 24. In this embodiment, the visualization experience is further enhanced, providing users with a clearer perspective and allowing them to observe effortlessly.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first opening 41 of the speaker cover 4 is provided with a first sealing ring 411 for sealing, and the outer edge of the cover 23 is provided with a second sealing ring 234 for sealing.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the host 1 and / or the milk bowl 2 are provided with a first force-bearing part 100 to facilitate the separation of the host 1 and the milk bowl 2, and the cover 23 is provided with a second force-bearing part 200 to facilitate the separation of the cover 23 and the bowl 24.

[0044] In this embodiment, an easy-to-apply force point is provided for the user, which solves the problems of difficult disassembly and easy slippage caused by the smooth shape and tight sealing between components of traditional wearable breast pumps. This greatly improves the convenience and safety of disassembly and cleaning after product use.

[0045] In this second embodiment, as Figure 9As shown, the main unit 1 is located below the milk suction channel 232. The main unit 1 and the milk storage bowl 2 are assembled and fixed by snap fasteners. The one-way valve 222 is a plate-shaped one-way valve.

[0046] In this third embodiment, as Figure 10 As shown, the main unit 1 and the milk storage bowl 2 are assembled using threads. External threads can be provided on the connecting edge of the main unit 1, and corresponding internal threads can be provided on the corresponding edge of the milk storage bowl 2, or vice versa. This solution aims to address the problem of insufficient sealing pressure or loosening of connections that may occur due to tolerances or wear from long-term use in some snap-fit ​​connections.

[0047] The working principle of this embodiment is as follows: This application discloses a wearable breast pump that greatly improves the utilization rate of the internal space and the convenience of use by using a vertically parallel and detachable connection between the main unit and the milk storage bowl. This optimized layout allows for the inclusion of a larger capacity milk storage bowl while effectively controlling the overall thickness of the product, solving the technical pain point of existing products that are difficult to balance size and capacity. At the same time, it also allows the overall structure of the product to be designed to be more compact and small, thereby significantly improving the user's wearing comfort and concealment.
