[0002] A breast pump is a tool that helps mothers collect breast milk, especially suitable for mothers who cannot breastfeed directly or need to store breast milk for later use. The design of a breast pump mimics a baby's sucking motion, effectively stimulating the breasts to produce milk and extracting it.

[0003] Existing breast pumps with heating functions mainly connect to the heating element via POGOPIN connectors. The POGOPIN connector and the power connection component make point contact with each other. During the heating process, the heating element generates a large current. Under prolonged exposure to this large current, the contact points of the POGOPIN connector are prone to breakdown and oxidation, resulting in a loss of power and failure of the heating function. This leads to a poor user experience. Therefore, it is necessary to improve the connector of the breast pump to reduce the failure rate and better extend the lifespan of the heated breast pump and improve the user experience.

[0026] Example 1

[0027] like Figures 1 to 5 The illustrated heated breast pump includes a cover 1 and a main unit 2 connected to the cover 1. The cover 1 is provided with a heating component 3 for generating heat and a cover connector 4 connected to the heating component 3. The main unit 2 is provided with a main unit connector 5 that is conductive to the cover connector 4. The cover connector 4 and / or the main unit connector 5 are provided with an annular conductive end 6 for increasing the conductive contact area.

[0028] Compared to the point contact method of the original POGOPIN connector, this utility model increases the conductive contact area by setting an annular conductive end, which allows the current to have a wider and more stable path. This can effectively reduce the current density at the contact point, avoid the contact point being broken down due to excessive local current, ensure that the current can continuously and stably pass through the connector, maintain the normal power supply of the heating component, and reduce the problem of heating function failure due to poor contact.

[0029] Specifically, the increased contact area makes heat dissipation at the contact point more uniform, reducing the likelihood of localized overheating. The annular conductive end delays the process of the contact point turning black due to oxidation, which affects conductivity and extends the lifespan of the connector, indirectly improving the overall durability and service life of the heated breast pump.

[0030] Optionally, in some embodiments, when the housing connector is provided with an annular conductive end, the host connector may be provided with a planar contact end. When the annular conductive end contacts the host connector, the annular contact area can reduce the current density at the contact point and avoid excessive local current.

[0031] Optionally, in some embodiments, when the host connector has an annular conductive end, the housing connector may have a planar contact end. When the annular conductive end contacts the housing connector, the annular contact area can reduce the current density at the contact point and avoid excessive local current.

[0032] Optionally, in some embodiments, when the housing connector is provided with an annular conductive end, the host connector may be provided with a planar contact end. When the annular conductive end contacts the host connector, the annular contact area can reduce the current density at the contact point and avoid excessive local current.

[0033] Optionally, in some embodiments, when the host connector is provided with an annular conductive end and a planar contact end, the housing connector is provided with an annular conductive end and a planar contact end. When the annular conductive end of the host connector contacts the planar contact end of the housing connector, the annular contact area can reduce the current density at the contact point and avoid excessive local current.

[0034] Of course, in some embodiments, when the host connector is provided with an annular conductive end and the housing connector is provided with an annular conductive end, when the annular conductive end of the host connector contacts the annular conductive end of the housing connector, the annular contact area can reduce the current density at the contact point and avoid excessive local current.

[0035] Example 2

[0036] Example 2, based on Example 1, has the following implementation method:

[0037] like Figure 3 The illustrated heating breast pump has an annular guide end 6 comprising an annular protrusion 61 and an annular groove 62 that mates with the annular protrusion 61. One of the cover connector 4 and the main unit connector 5 is an annular protrusion 61, and the other is an annular groove 62.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the mating structure of the annular protrusion and the annular groove enables precise alignment between the cover connector and the main unit connector during connection. Compared to the traditional simple point contact method, the concave-convex mating of this utility model can effectively prevent the two from easily separating or misaligning due to accidental shaking, pulling, or other situations during use, ensuring the stability of the connection and thus ensuring that the current can be continuously and stably conducted, maintaining the normal heating function of the breast pump.

[0039] Specifically, the ring-shaped connection structure increases the conductive contact area, allowing the current to be distributed more evenly compared to the previous point contact, thus avoiding excessive local current. This even current distribution helps reduce the risk of contact point breakdown and also ensures a more balanced heat distribution across the entire connection when powered on, further reducing oxidation caused by localized overheating and extending the connector's lifespan.

[0040] In addition, during the assembly process, operators can perform the assembly operations of the housing connector and the main unit connector more intuitively and conveniently, which can effectively improve assembly efficiency and reduce the probability of errors in the assembly process.

[0041] Optionally, in some embodiments, the housing connector has an annular protrusion, the host connector has an annular groove, and the housing connector extends into the host connector for engagement and positioning.

[0042] Optionally, in some embodiments, the housing connector has an annular groove, the host connector has an annular protrusion, and the host connector extends into the housing connector for engagement and positioning.

[0043] Example 3

[0044] Example 3, based on Example 1, has the following implementation method:

[0045] like Figure 3 and Figure 4 The illustrated heating breast pump has a cover 1 with a horn cover 7, and a heating component 3 including a heating element 31 disposed on the horn cover 7 and a temperature sensor 32 connected to the heating element 31. The heating element 31 is connected to the cover connector 4.

[0046] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the horn cover is provided with a breast suction channel 71, and the heating element is located on the outside of the horn cover. The breast suction channel can be heated by the horn cover, which can make the breast milk be heated more evenly and accurately, avoid local overheating or underheating, and reduce the discomfort when the low-temperature cover comes into contact with the user's breast. In addition, the horn cover, which is close to the body temperature, can also stimulate the breast to secrete breast milk through a suitable temperature.

[0047] Specifically, the temperature sensor connected to the heating element can detect the temperature of the speaker cover in real time during the heating process, thereby adjusting the heating power of the heating element through the breast pump controller to maintain the temperature inside the speaker cover within a suitable range.

[0048] like Figures 2 to 5 The illustrated heating breast pump includes a front cover 7 comprising a front cover 11 and a rear cover 12 connected to the front cover 11. A heating element 31 is located between the front cover 11 and the rear cover 12. The rear cover 12 is provided with a rear cover receiving cavity 121 for fixing the cover connector 4. The cover connector 4 and the heating element 31 are respectively located on opposite sides of the rear cover receiving cavity 121.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the heating element is positioned between the front cover and the rear cover, protecting it from external impacts, pressure, dust, moisture, etc., thus helping to extend its service life and ensuring stable heating function. The cover connector is fixed within the rear cover cavity, reducing the risk of loosening or damage caused by external factors such as pulling or touching, and enhancing the stability of the entire connection structure.

[0050] In addition, placing the heating element and the cover connector on opposite sides of the rear cover cavity allows for efficient use of the internal space of the cover, which helps to reduce the overall size of the cover and makes the breast pump more compact and lightweight, making it easier to carry and store.

[0051] Optionally, in some embodiments, both the front cover 11 and the rear cover 12 are arranged in annular horn shapes.

[0052] like Figures 2 to 5 The illustrated heating breast pump has a front cover 11 with a front cover connecting groove 111 and a rear cover 12 with a rear cover connecting groove 122. The heating element 31 is connected between the front cover connecting groove 111 and the rear cover connecting groove 122 and is arranged around the inside of the horn cover 7.

[0053] Furthermore, as a preferred embodiment of this utility model and not a limitation, the heating element is arranged in a ring around the inside of the speaker cover, enabling all-round and uniform heating of the speaker cover. Compared with local heating, the ring-shaped layout allows heat to be transferred to the inside of the speaker cover from all angles, avoiding uneven heating.

[0054] Specifically, because the heating element is connected between the front cover connecting groove and the rear cover connecting groove, and is arranged around the inside of the horn cover, its contact area with the horn cover is relatively larger, the heat transfer path is more direct and efficient, and the heat can be relatively concentrated around the horn cover. Fixing the heating element through the front cover connecting groove and the rear cover connecting groove ensures a stable installation position for the heating element inside the cover, preventing displacement or loosening.

[0055] like Figures 3 to 5 The illustrated heating breast pump has a main unit 2 with a main unit housing 21. The main unit housing 21 has a main unit housing receiving cavity 211 into which the main unit connector 5 extends, and a main unit housing connecting end 212. The main unit connector 5 has a connector boss 51 that extends into the main unit housing receiving cavity 211, and a main unit connector mating end 52 that connects to the connector boss 51 and mates with the main unit housing connecting end 212. The annular guide end 6 is disposed in the connector boss 51.

[0056] Furthermore, as a preferred embodiment of this utility model and not a limitation, the main unit connector is provided with a connector boss extending into the receiving cavity of the main unit housing, and the main unit connector mating end mates with the main unit housing connection end. This arrangement allows the main unit connector to achieve a stable installation and positioning within the main unit housing. The annular conductive end is located within the connector boss. When mating with the corresponding connector, on the one hand, the stable overall structure prevents the connection stability from being affected by shaking or loosening; on the other hand, it ensures accurate alignment of the annular conductive end, stably increasing the conductive contact area, ensuring stable and smooth current flow, maintaining good conductivity between the components of the heated breast pump, and reducing malfunctions caused by poor contact.

[0057] Optionally, in some embodiments, the connector boss can be connected to the mating end of the host connector by ultrasonic welding, snap-fit ​​connection, or magnetic connection.

[0058] Optionally, in some embodiments, the main unit housing connection end and the main unit connector mating end can be connected by fastener thread connection, snap connection, mortise and tenon connection, ultrasonic welding, magnetic connection, or other methods.

[0059] like Figures 3 to 5 The illustrated heating breast pump has a rear cover 12 with a rear cover guide end 123 for connecting to the temperature sensor 32. The contact ends of the cover connector 4 are in contact with the temperature sensor 32 and the heating element 31, respectively.

[0060] In addition, the rear cover is equipped with a connecting end for a temperature sensor, which enables the temperature sensor to obtain temperature information near the horn cover in real time and accurately, ensuring the safety and stability of the breast pump during use and extending the product's service life.

[0061] Optionally, the housing connector is a conductive circular connector, with two of its contact ends contacting the two ends of the annular heating element, and one contact end of the housing connector contacting the temperature sensor.

[0062] Optionally, in some embodiments, the heating element is a non-enclosed annular type.

[0063] Optionally, in some embodiments, the rear cover guide end is a connecting groove, and the temperature sensor is engaged on the rear cover guide end to maintain a stable position.

[0064] Optionally, in some embodiments, the rear cover guide end can be a connecting bracket. The temperature sensor is assembled to the rear cover guide end by means of snap-fit ​​connection, fastener screw connection, magnetic connection, etc., thereby restricting the movement of the temperature sensor.

[0065] Example 4

[0066] Example 4, based on Example 1, has the following implementation method: Figures 3 to 5 The illustrated heating breast pump has multiple sets of annular guide ends 6. Each annular guide end 6 includes annular protrusions 61 and annular grooves 62. An annular groove 62 is formed between two annular protrusions 61, and an annular protrusion 61 is formed between two annular grooves 62. Both the cover connector 4 and the main unit connector 5 are provided with the annular guide ends 6 and are connected to each other.

[0067] Furthermore, as a preferred embodiment of this utility model and not a limitation, multiple sets of annular conductive terminals are provided. Compared to a single set or traditional point contact method, this greatly increases the conductive contact area between the housing connector and the main unit connector. When current passes through the connector, it can be distributed across multiple annular conductive areas, effectively reducing the current density at each contact point. This significantly reduces the risk of current breakdown at the contact point, ensuring stable and smooth current conduction between the two, maintaining the normal operation of all functions of the heated breast pump, and improving the electrical performance stability of the product.

[0068] Specifically, the nested structure of the annular protrusions and annular grooves provides excellent positioning and anti-detachment performance, creating multiple stable connection points between the cover connector and the main unit connector. This better resists the effects of external pulling, shaking, and plugging / unplugging during the use of the breast pump, preventing loosening or disconnection of the connector and ensuring reliable connection during long-term use.

[0069] Optionally, in some embodiments, an annular groove is formed between two adjacent annular protrusions, and an annular protrusion is formed between two adjacent annular grooves. The annular protrusion and the annular groove of the host connector coincide in center, and the annular protrusion and the annular groove of the housing connector coincide in center. The annular protrusion of the housing connector extends into the annular groove of the host connector, and at the same time, the annular protrusion of the host connector extends into the annular groove of the housing connector.

[0070] Optionally, in some embodiments, multiple sets of annular conductive ends can be arranged at horizontal intervals within the housing connector, and multiple sets of annular conductive ends can be arranged at horizontal intervals within the host connector.

[0071] Optionally, in other embodiments, multiple sets of annular conductive ends may be arranged at intervals in the vertical direction within the housing connector, and multiple sets of annular conductive ends may be arranged at intervals in the vertical direction within the host connector.

[0072] Example 5

[0073] Example 5, based on Example 3, has the following implementation method:

[0074] like Figures 1 to 5 The illustrated heating breast pump has a rear cover 12, a heating element 31, and a cover connector 4 that are coated with rubber to form a heating rear cover assembly 8.

[0075] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the small gaps between the rear cover, heating element, and cover connector can be filled by overmolding, making the connection more secure and enhancing the overall structural strength of the support component. The rear cover, heating element, and cover connector are integrated into a heated rear cover assembly, making the heated rear cover assembly more compact and stable. During daily use of the breast pump, even under external impact, vibration, or frequent plugging and unplugging operations, the components are less likely to loosen, shift, or detach.

[0076] At the same time, the overmolding process also reduces a lot of component assembly and debugging time and potential assembly errors, effectively improving production efficiency. It also helps to ensure product quality consistency and reduce product defect rate.

[0077] Of course, in subsequent assembly, the front cover and the rear heating cover assembly can be reassembled using methods such as snap-fit ​​connection, fastener connection, injection molding connection, magnetic connection, and mortise and tenon connection.

[0078] Example 6

[0079] Example 6, based on Example 5, has the following implementation method:

[0080] like Figures 1 to 5 The illustrated heating breast pump has a front cover 11 and a rear heating cover assembly 8 formed by rubber coating to form the cover 1.

[0081] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the front cover and the heated rear cover assembly are integrated into a complete cover body by overmolding, making the connection between the parts tighter and more secure. Overmolding makes the overall appearance of the cover body more refined and smooth, improving the overall aesthetics of the breast pump.

[0082] Example 7

[0083] Example 7, based on the above examples, has the following implementation method:

[0084] The heating component 3 includes at least one of the following: a metallic material, a conductive polymer material, a conductive coating, carbon fiber, or graphene.

[0085] Specifically, metallic materials have good electrical and thermal conductivity, as well as high strength and stability. Metallic materials can be nickel-chromium alloys with good high-temperature resistance and stable resistivity, or copper with good electrical conductivity and high thermal conductivity.

[0086] Specifically, conductive polymer materials have good electrothermal conversion properties. Conductive polymer materials can be polyaniline materials that are made into filaments after doping treatment and can exhibit good conductivity, or they can be conductive rubber with good conductivity and flexibility formed by uniformly dispersing conductive particles in a rubber matrix.

[0087] Specifically, the conductive coating can be a carbon film coating with good conductivity and thermal stability, or a silver nanoparticle coating.

[0088] Specifically, carbon fiber has high strength, high modulus and good electrical conductivity, and can be carbon fiber heating wire or polyacrylonitrile-based carbon fiber.

[0089] Specifically, graphene has extremely high electrical and thermal conductivity, which can be used to make graphene heating films or graphene heating coatings that are attached to the speaker cover.

[0090] Optionally, in some embodiments, the heating element 31 of the heating assembly 3 is made of copper, a metallic material.

[0091] Example 8

[0092] Example 8, based on the above examples, has the following implementation method:

[0093] The heating component 3 has a cross-section that is one of the following: snake-shaped, ring-shaped, square-shaped, wave-shaped, sawtooth-shaped, grid-shaped, or Z-shaped.

[0094] Furthermore, as a preferred embodiment of this utility model and not a limitation, the heating element 31 of the heating assembly 3 can be arranged in a roundabout manner between the front cover and the rear cover, for example, in a continuous wave shape, continuous serpentine shape, continuous zigzag shape, continuous square shape, or continuous Z-shape. This can increase the contact range and contact time between the heating element and the speaker cover, allowing heat to be transferred more evenly and comprehensively to the emulsion inside the speaker cover. Compared to a simple single-ring layout, the roundabout arrangement can avoid localized excessive heat concentration or insufficient heating in certain areas, resulting in more even heating of the front cover.

[0095] Specifically, because the heating elements are distributed in a roundabout manner, the heat transfer path is extended within a limited space, reducing heat loss to other unnecessary directions. More heat can be focused around the horn cover, thus making more efficient use of the heat generated to heat the emulsion.

[0096] Of course, the heating element can adopt a grid-like or multiple concentric ring layout. By adjusting the spacing between the patterns, a more efficient heating method can be customized, which is suitable for applications that require rapid heating or are suitable for applications with low ambient temperatures.

[0097] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
