Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, specifically a magnetic heating component and a breast pump. Background Technology

[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] Traditional breast pumps generally lack heating functions, which is particularly problematic in winter. When the ambient temperature is low, the shield covering the breast can lower the user's perceived temperature, and milk cannot quickly collect in the container at low temperatures, leading to reduced pumping efficiency. Therefore, the structure of breast pumps needs to be improved to enhance their practicality and user experience. Utility Model Content

[0004] Regarding the aforementioned technical problem that existing breast pumps lack a heating function, resulting in decreased perceived temperature and reduced pumping efficiency when used in low ambient temperatures, the technical solution adopted by this utility model is as follows:

[0005] A magnetic heating assembly includes a cover assembly and a housing connected to the cover assembly. The cover assembly has a cover channel, a heating device for transferring heat to the cover channel, and a first magnetic member. The housing has a control device that can communicate with the heating device and a second magnetic member. The first magnetic member and the second magnetic member are brought close together or separated to allow the cover assembly and the housing to switch between an installed state and a disassembled state.

[0006] Furthermore, in some embodiments of this utility model, the cover assembly includes a cover and a mounting base, the cover and the mounting base enclose a cover receiving cavity, and the heating device includes a heating element disposed in the cover receiving cavity and a connecting terminal connected to the heating element and extending to the outside of the mounting base.

[0007] Furthermore, in some embodiments of this utility model, the shroud cavity is located outside the shroud channel, and the cross-section of the heating element is one of the following: serpentine, annular, semi-circular, square, wavy, sawtooth, grid, or Z-shaped.

[0008] Furthermore, in some embodiments of this utility model, the first magnetic suction member is disposed between the heating member and the connecting terminal.

[0009] Furthermore, in some embodiments of this utility model, the first magnetic suction member is located inside the cavity of the cover, and the cross-section of the first magnetic suction member is one of polygonal, circular, annular, elliptical, fan-shaped, semi-circular, I-shaped, L-shaped, T-shaped, and V-shaped.

[0010] Furthermore, in some embodiments of this utility model, the housing is provided with a housing cavity and a housing channel communicating with the cover channel, the second magnetic attractor is provided on the outside of the housing channel, and the cross-section of the second magnetic attractor is one of polygonal, circular, annular, elliptical, fan-shaped, semi-circular, I-shaped, L-shaped, T-shaped, and V-shaped.

[0011] Furthermore, in some embodiments of this utility model, the housing is provided with a housing opening for the connecting terminal to extend into the housing cavity, and a control device that can communicate with the heating device. The control device is provided with a main board component that communicates with the connecting terminal.

[0012] Furthermore, in some embodiments of this utility model, the second magnetic suction member is located between the housing opening and the main board component.

[0013] Furthermore, in some embodiments of the present invention, the housing is provided with an extension portion extending away from the cover assembly, the housing channel is located within the extension portion, and the housing receiving cavity is provided with a fixing cavity located on the outer periphery of the extension portion for fixing the second magnetic member.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention, by setting a first magnetic suction component and a second magnetic suction component, allows the cover assembly and the housing to be flexibly switched between an installed state and a disassembled state.

[0025] Example 1

[0026] like Figures 1 to 5 The magnetic heating assembly shown includes a cover assembly 1 and a housing 2 connected to the cover assembly 1. The cover assembly 1 has a cover channel 3, a heating device 4 for transferring heat to the cover channel 3, and a first magnetic member 5. The housing 2 has a second magnetic member 7. The first magnetic member 5 and the second magnetic member 7 are brought close together or separated, so that the cover assembly 1 and the housing 2 can be switched between an installed state and a disassembled state.

[0027] This invention, by setting a first magnetic suction component and a second magnetic suction component, allows the cover assembly and the housing to be flexibly switched between an installed state and a disassembled state. After the cover assembly and the housing are installed, the heating device generates heat and transfers heat to the cover channel, effectively increasing the temperature of the part of the cover assembly that contacts the breast, avoiding the user's discomfort due to low temperature contact, and helping the milk to flow more smoothly and quickly, thereby improving the overall efficiency of breastfeeding and saving breastfeeding time.

[0028] Specifically, this utility model, by setting a first magnetic suction component and a second magnetic suction component, allows the first and second magnetic suction components to be close to each other in the installation state, which can facilitate the quick and easy installation of the cover assembly and the housing. When the heating function is needed, the power is turned on, the heating device heats up and transfers heat to the cover channel; when the heating function is not needed, the power can be turned off, the heating device stops heating. When the breast pump is switched to the disassembly state, such as when the breast pump needs to be cleaned or stored, the first and second magnetic suction components can be moved away from each other, which can easily detach the cover assembly and the housing, thereby enhancing the overall convenience of using the breast pump.

[0029] Additionally, when the heating device transfers heat to the breast pump channel, it effectively stimulates milk secretion and improves user comfort, allowing the user to be in a relatively warm and comfortable state during breastfeeding. The increased local ambient temperature in the breast pump channel reduces milk movement obstruction caused by low temperatures, thereby improving milk fluidity and aggregation.

[0030] Optionally, in some embodiments, the heating device can be electrically connected to the control device, which can be located inside the cover assembly, on the housing, or outside the magnetic heating assembly.

[0031] like Figures 2 to 5 The magnetic heating assembly shown includes a cover assembly 1 comprising a cover 11 and a mounting base 12, wherein the cover 11 and the mounting base 12 enclose a cover receiving cavity 13, and the heating device 4 comprises a heating element 41 disposed in the cover receiving cavity 13 and a connecting terminal 42 connected to the heating element 41 and extending to the outside of the mounting base 12.

[0032] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the heating element is disposed within the cavity of the cover body, so that the heating element can heat the cover body at close range and more evenly, and the heat can be more effectively transferred to the part of the cover body that is in contact with the user's breasts, thereby stably increasing the temperature of the cover body and improving the user's comfort during use.

[0033] Additionally, in some embodiments, externally exposed connection terminals facilitate connection of the heating device to the housing assembly or control devices on the casing, reducing the risk of tangled or loose wiring. External connection terminals also provide greater clarity during installation and removal, facilitating alignment and insertion, thus increasing assembly flexibility.

[0034] Optionally, the heating element is a PCBA heating plate, and the heating element is equipped with an NTC temperature sensor. When the heating element is connected to the control device, the NTC temperature sensor can transmit a signal to the control device based on the detected temperature, and then the control device can adjust the temperature to achieve stable heating.

[0035] Example 2

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

[0037] like Figure 3 and Figure 5 The magnetic heating assembly shown has a housing cavity 13 located outside the housing channel 3, and the heating element 41 has a cross-section that is one of the following: serpentine, annular, semi-circular, square, wavy, sawtooth, grid, or Z-shaped.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation, the heating element can be arranged in a circuitous manner within the housing cavity, for example, using a continuous wave shape, a continuous serpentine shape, a continuous zigzag shape, or a continuous Z-shape. This increases the contact area and contact time between the heating element and the housing assembly, allowing heat to be transferred more evenly and comprehensively to the emulsion within the housing assembly. Compared to being positioned on one side of the housing assembly, the circuitous arrangement avoids excessive local heat concentration or insufficient heating in certain areas, resulting in more even heating of the housing assembly.

[0039] 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 cover channel, thus making more efficient use of the heat generated to heat the emulsion.

[0040] 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.

[0041] Of course, the heating element can be arranged in a semi-circular shape on the side near the cover channel.

[0042] Alternatively, the heating element can be a closed ring, such as a circular ring, an elliptical ring, or a polygonal ring, such as a ring with a square cross-section. It can also be an open ring structure, such as a semi-circular ring or a horseshoe-shaped ring, depending on the manufacturing process.

[0043] Optionally, in some embodiments, the annular heating element is arranged around the outer side of the cover channel within the cover's receiving cavity. This arrangement allows for comprehensive and uniform heating of the cover channel, resulting in a more even temperature distribution throughout the cover. The user's breasts are exposed to a relatively consistent warm environment, thus enhancing comfort. Milk flows smoothly into the container in this uniformly warm environment, effectively improving milk expression efficiency and avoiding problems such as slow milk flow due to low temperatures.

[0044] Specifically, the ring-shaped structure is relatively stable, and the heating element can be firmly installed in the housing cavity, making it less prone to positional displacement, thus ensuring the continuous and stable heating function.

[0045] like Figure 3 and Figure 5 The magnetic heating assembly shown has a first magnetic element 5 disposed between the heating element 41 and the connecting terminal 42.

[0046] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, arranging the first magnetic suction member between the heating member and the connecting terminal can fully utilize the space of the cover assembly, avoiding excessive space occupation in other parts of the breast pump, making the internal structure of the breast pump more compact and orderly. The first magnetic suction member can be closer to the second magnetic suction member, and the alignment is more accurate and faster. At this time, the rear end of the mounting base abuts against the front end of the shell, and its adsorption force is greater, thereby improving the stability of the connection.

[0047] Of course, the first magnetic component is made of metal, such as stainless steel, iron, copper, or aluminum. Specifically, in this embodiment, the first magnetic component is made of stainless steel. In some embodiments, the connecting terminal can be connected to the heating element through the first magnetic component. In other embodiments, the first magnetic component has corresponding openings, through which the connecting terminal can pass to connect to the heating element. In still other embodiments, the non-enclosed first magnetic component has a hollow portion, allowing the connecting terminal to pass through the hollow portion and connect to the heating element.

[0048] Optionally, in some embodiments, the first magnetic element may be located at the end of the mounting base.

[0049] like Figure 3 and Figure 5The magnetic heating assembly shown has a first magnetic element 5 located inside the housing cavity 13. The cross-section of the first magnetic element 5 is one of polygonal, circular, annular, elliptical, fan-shaped, semi-circular, I-shaped, L-shaped, T-shaped, or V-shaped.

[0050] Furthermore, as a preferred embodiment of this utility model and not a limitation, the annularly arranged first magnetic member can achieve uniform force within the housing cavity, and the first magnetic member is not easily loosened within the housing cavity. When the housing assembly and the shell are installed close together, due to the annular structure of the first magnetic member, magnetic attraction can be generated at all parts, making the connection between the housing assembly and the shell more stable and uniform. There is no loosening or misalignment caused by uneven local attraction, thereby ensuring that the heating device can be stably connected to the control device through the connection terminal.

[0051] Specifically, since the first magnetic suction element is located inside the housing cavity, the annular structure of the first magnetic suction element will not hinder the heat transfer generated by the heating element. Optionally, in some embodiments, the first magnetic suction element can reduce the heat exchange between the housing cavity and the outside to a certain extent, play a certain heat preservation role, and allow the heated housing to better maintain a suitable temperature, further improving the user's comfort in low-temperature environments and also helping to improve milk pumping efficiency.

[0052] Of course, the first magnetic element can be a closed ring, such as a circular ring, an elliptical ring, or a polygonal ring, such as a ring with a square cross-section. It can also be a non-closed ring structure, such as a semi-circular ring or a horseshoe-shaped ring, depending on the manufacturing process.

[0053] In other embodiments, the first magnetic attractor may be circular, polygonal, elliptical, fan-shaped, or semi-circular and disposed on one side of the housing cavity, or multiple first magnetic attractors may be evenly disposed within the housing cavity. The polygon may be triangular, square, rhomboid, rectangular, trapezoidal, hexagonal, or similar shapes.

[0054] In addition, the housing cavity can be configured in the shape of I, L, T, V, etc., for the corresponding shape of the first magnetic suction component to be fixedly connected. The first magnetic suction component can be configured in the shape of I, L, T, V, etc. and fixed in the housing cavity by means of snap connection, fastener connection, mortise and tenon connection, etc.

[0055] Example 3

[0056] Example 3, based on Example 2, has the following implementation method:

[0057] like Figure 3 and Figure 5The magnetic heating assembly shown has a housing 2 with a housing cavity 21 and a housing channel 22 communicating with the cover channel 3. The second magnetic member 7 is located on the outside of the housing channel 22. The cross-section of the second magnetic member 7 is one of polygonal, circular, annular, elliptical, fan-shaped, semi-circular, I-shaped, L-shaped, T-shaped, and V-shaped.

[0058] Furthermore, as a preferred embodiment of this utility model and not a limitation, the second magnetic suction member is arranged in a ring around the outer side of the housing channel, corresponding to the first magnetic suction member arranged in a ring inside the cover cavity. When the cover assembly and the housing are close to each other, the cover assembly and the housing can be tightly and firmly joined together by the stable and uniform attraction between the ring magnetic suction members, ensuring the structural stability of the entire breast pump after assembly. This ensures that during use, whether it is the slight shaking caused by the breast pumping operation or daily movement, picking up and putting down, the cover assembly and the housing will not easily separate, ensuring that the breast pump can function normally.

[0059] Optionally, in some embodiments, the heating element and the first magnetic suction element are located inside the housing cavity. Heat is transferred from the first magnetic suction element to the second magnetic suction element inside the housing through the rear end of the mounting base. The second magnetic suction element can transfer temperature to the housing channel, thereby playing a certain heat preservation role, so that the heated milk can be better maintained in a suitable temperature environment when flowing through the housing channel and the housing channel.

[0060] Of course, the second magnetic element can be a closed ring, such as a circular ring, an elliptical ring, or a polygonal ring, such as a ring with a square cross-section. It can also be an open ring structure, such as a semi-circular ring or a horseshoe-shaped ring, depending on the manufacturing process.

[0061] In other embodiments, the second magnetic attractor may be circular, polygonal, elliptical, fan-shaped, or semi-circular and disposed on one side of the housing cavity, or multiple second magnetic attractors may be evenly disposed within the housing cavity. The polygon may be triangular, square, rhomboid, rectangular, trapezoidal, hexagonal, or similar shapes.

[0062] In addition, the fixing cavity provided in the housing cavity can be set in the shape of I, L, T, V, etc., for the corresponding shape of the second magnetic suction member to be fixedly connected. The second magnetic suction member can be set in the shape of I, L, T, V, etc. and fixed in the fixing cavity by means of snap connection, fastener connection, mortise and tenon connection, etc.

[0063] Of course, the second magnetic component is made of metal, such as stainless steel, iron, copper, or aluminum. Specifically, in this embodiment, the second magnetic component is made of stainless steel.

[0064] like Figures 2 to 5The magnetic heating assembly shown has a housing 2 with a housing opening 23 for the connection terminal 42 to extend into the housing cavity 21, and a control device 6 that can communicate with the heating device 4. The control device 6 has a main board component 61 that communicates with the connection terminal 42.

[0065] Furthermore, as a preferred embodiment of this utility model and not a limitation, by providing an opening in the housing, the connecting terminals on the cover assembly can smoothly extend into the housing cavity, thereby communicating with the main board of the control device. This ensures the transmission of electrical energy and control signals required for the heating function, allowing the heating device to work accurately according to the preset control logic of the main board. Optionally, in some embodiments, the main board can be precisely adjusted according to the user's set temperature level, heating time, and other requirements, making it convenient for the user to operate and effectively achieving flexible control of the cover temperature, thus improving the convenience and comfort of use.

[0066] Specifically, this utility model, by setting a first magnetic suction component and a second magnetic suction component, allows the first and second magnetic suction components to be close to each other in the installation state, facilitating the quick and easy installation of the cover assembly and the housing. The heating device can be connected to the control device. When the heating function is needed, the power is turned on, and the control device and the heating device are connected, thereby enabling the heating device to generate heat and transfer heat to the cover channel. When the heating function is not needed, the power can be turned off, thereby disconnecting the control device from the heating device. When the breast pump is switched to the disassembly state, such as when cleaning or storing the breast pump, the first and second magnetic suction components can be moved away from each other, allowing the cover assembly and the housing to be easily disassembled, thereby enhancing the overall convenience of using the breast pump.

[0067] Furthermore, connecting the connector terminals to the main board components inside the housing through openings in the housing provides better protection for the electrical connections. Compared to exposed connector terminals, the relatively enclosed environment inside the housing reduces the impact of external physical collisions, moisture corrosion, and dust contamination on the main board components, decreasing the probability of electrical faults such as short circuits and poor contact. This ensures the safety of the breast pump during use and extends the product's lifespan.

[0068] like Figures 2 to 5 The magnetic heating assembly shown has a second magnetic element 7 located between the housing opening 23 and the main board 61.

[0069] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the second magnetic member is positioned between the housing opening and the main board component, and the second magnetic member is closer to the first magnetic member, resulting in a stronger magnetic attraction between the cover assembly and the housing. When the cover assembly is installed onto the housing, the connecting terminals on the cover assembly can precisely extend through the housing opening to the corresponding position on the main board component, making the connection operation smoother and more accurate.

[0070] Of course, in some embodiments, when installation or disassembly is performed, the second magnetic component, which is not enclosed and has a hollowed-out portion, is connected to the main board component through the hollowed-out portion. This can avoid problems such as loosening of the connection terminal, displacement of the circuit, or poor contact caused by external force pulling, and ensure that the electrical connection between the heating device and the main board component is always stable and reliable, thereby ensuring that the heating function can continue to operate normally and improving the stability of the breast pump.

[0071] like Figures 2 to 5 The magnetic heating assembly shown has a housing 2 with an extension 24 extending away from the cover assembly 1, a housing channel 22 located within the extension 24, and a housing cavity 21 with a fixing cavity 241 located on the outer periphery of the extension 24 for fixing the second magnetic member 7.

[0072] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the shell channel is arranged in the extension portion extending away from the cover assembly, so that the milk has a relatively independent and smooth path as it flows from the cover channel to the subsequent collection part. This ensures the stability and smoothness of the milk transfer from the cover to the shell during the milking process, and reduces the occurrence of milk backflow, blockage, and other situations that affect the milking efficiency and milk quality due to unreasonable spatial layout.

[0073] Specifically, the extension provides additional support and protection for the housing channel and the second magnetic component. By setting a fixing cavity on the outer periphery of the extension to fix the second magnetic component, on the one hand, the space between the housing opening and the main board component can be fully utilized, avoiding the occupation of too much other space inside the breast pump, making the internal structure of the breast pump more compact and reasonable. On the other hand, this fixing method can ensure that the second magnetic component can always remain in the accurate position during the use of the breast pump, whether it is daily handling, movement, or slight vibrations during breast pumping operations, without displacement or loosening, thereby ensuring a stable and reliable magnetic attraction between the second magnetic component and the first magnetic component, and maintaining a firm connection between the cover assembly and the housing.

[0074] Example 4

[0075] Example 4, based on the above examples, has the following implementation method:

[0076] like Figures 1 to 5 The breast pump shown includes the magnetic heating assembly as described above.

[0077] In low-temperature environments, traditional breast pumps can lower the user's perceived temperature. This new breast pump uses a magnetic heating component that can transfer heat through the pump's channels, effectively warming the area in contact with the breast, preventing the user from feeling cold and uncomfortable, and improving overall user comfort.

[0078] Low temperatures can also cause milk to have difficulty quickly pooling in the container, thus reducing pumping efficiency. This new breast pump uses a magnetic heating component that heats the environment around the pump's channels, allowing the milk to flow and pool more smoothly and quickly in warm conditions. This reduces the obstruction caused by low temperatures, effectively shortens pumping time, and makes the pumping process more efficient, saving users time and effort.

[0079] This invention relates to a breast pump that, through the inclusion of a first magnetic chuck and a second magnetic chuck, allows for switching between an installed and detached state between the shield assembly and the housing. When the shield assembly and housing are magnetically attached, the heating function can be activated to improve milk expression efficiency when needed. When the heating function is not required, the shield assembly and housing can be easily detached, simplifying operation and enhancing the flexibility and convenience of the breast pump in daily use.

[0080] 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.
