[0061] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0062] Please refer to the following: Figures 1 to 7 This utility model provides a breast pump 100, including a main unit module 1 and a breast pump flange assembly 2. A connection structure 3 is provided between the main unit module 1 and the breast pump flange assembly 2. The connection structure 3 is used to detachably connect the breast pump flange assembly 2 to the main unit module 1, so as to facilitate the user to disassemble the breast pump flange assembly 2. The breast pump flange assembly 2 includes a breast pump flange 21, a heating component 22, and a temperature sensor 222. The main unit module 1 is electrically connected to the heating component 22 and the temperature sensor 222 through the connection structure 3. The heating component 22 is connected to the breast pump flange 21, and the temperature sensor 222 is connected to the heating component 22 or the breast pump flange 21.

[0063] When a user uses the breast pump 100, the user can choose to appropriately heat the breast through the heating component 22 connected to the breast pump flange 21. This can improve local blood circulation in the breast to a certain extent and reduce the viscosity of the milk to a certain extent, making the milk easier to flow in the mammary ducts, thus promoting lactation. The main unit module 1 can be electrically connected to the heating component 22 and the temperature sensor 222 through the connection structure 3. While the main unit module 1 and the breast pump flange assembly 2 are positioned and connected through the connection structure 3, the main unit module 1 is also electrically connected to the heating component 22 and the temperature sensor 222.

[0064] By implementing the above scheme, the milk suction flange assembly 2 is detachably connected to the main unit module 1, making it easy for users to install and remove the milk suction flange assembly 2; at the same time, the electrical connection between the heating component 22, the temperature sensor 222 and the main unit module 1 can be completed by assembling and connecting the milk suction flange assembly 2 and the main unit module 1 through the connection structure 3. The structure is reasonable and the use of the breast pump 100 is more convenient.

[0065] In the breast pump flange assembly 2, a temperature sensor 222 can acquire a temperature sensing signal. The breast pump 100 can control the heating power of the heating element 22 based on the temperature sensing signal obtained by the temperature sensor 222. For example, when the temperature sensor 222 detects that the temperature has reached the user-set range, it reduces or stops the current and / or voltage of the main unit module 1 to the heating element 22; or, when the temperature sensor 222 detects that the temperature exceeds the safety limit, the main unit module 1 disconnects the power supply to the heating element 22 to prevent the heating element 22 from heating uncontrollably and avoid scalding the user. Through the temperature sensing signal obtained by the temperature sensor 222, the main unit module 1 can adjust the current and / or voltage of the heating element 22. In this way, the heating element 22 of the breast pump 100 can stabilize the temperature, making it safer for the user and improving the user's breast pumping comfort.

[0066] Temperature sensor 222 is connected to heating component 22 or milk suction flange 21, so that temperature sensor 222 can obtain the temperature of the side of breast pump 100 in contact with human body / temperature of heating component more accurately.

[0067] In some embodiments, the heating component 22 is at least partially embedded in the milk suction flange 21, or the heating component 22 is at least partially disposed on the side of the milk suction flange 21 facing the user's breast.

[0068] Since the heating component 22 can be embedded in the milk suction flange 21, the heating component 22 heats the milk suction flange 21 more directly and the heating speed is faster. It can also make the heating component 22 closer to the user's skin, avoiding the problem of slow heat conduction caused by the milk suction flange 21 being too thick. The heating rate of the breast pump 100 is relatively fast, the user experience is better, and it is conducive to promoting lactation.

[0069] In specific applications, the heating component 22 can also be partially or entirely disposed on the side of the breast pumping flange 21 facing the user's breast. The heating component 22 can be provided with a flexible or elastic shell (e.g., a silicone sleeve), so that the shell of the heating component 22 can directly contact the user's breast, resulting in relatively higher heating efficiency. In this embodiment, the heating component 22 is embedded in the breast pumping flange 21.

[0070] In some embodiments, the heating assembly 22 includes a heating element 221, which can be built into the milk suction flange 21 or mounted on the surface of the milk suction flange 21 after being placed in a silicone sleeve. In this embodiment, the heating element 221 is embedded in the milk suction flange 21 as an example.

[0071] In some embodiments, the milk suction flange 21 is provided with one or at least two heating zones 5 in a radial direction, and each heating zone 5 is provided with at least one of the heating components 22 (heating elements 221).

[0072] Please refer to the following: Figure 11 The area on the milk suction flange 21 that is heated by the heating element 221 is the heating area 5. Figure 11 (The shaded area in the image). The breast pump flange 21 may be provided with one heating zone 5, or the breast pump flange 21 may be provided with at least two heating zones 5. Different heating zones 5 may be provided with independent heating elements 221, so that the breast pump flange assembly 2 can independently heat different areas of the user's breast. For example, the heating temperature in the area relatively far away from the user's nipple may be relatively higher, and the heating temperature in the area relatively close to the user's nipple may be relatively lower.

[0073] Specifically, the heating element 221 can be a heating film, such as a graphene flexible electric heating film or a polymer electric heating film. Alternatively, the heating assembly 22 can also include a heating wire to heat the milk suction flange 21.

[0074] In some embodiments, each heating zone 5 is provided with at least one of the temperature sensors 222, so that the temperature of different heating zones 5 can be obtained respectively. For example, when the milk suction flange 21 is provided with two heating zones 5, the two temperature sensors 222 are respectively provided in different heating zones 5.

[0075] In some embodiments, temperature sensors 222 can be respectively installed at two different locations within a heating zone 5, and the temperature sensors 222 at the two different locations within a heating zone 5 can obtain the accurate temperature at different locations within a heating zone 5. It is understood that when there is more than one temperature sensor 222 in the breast pump 100, the multiple temperature sensors 222 are connected in parallel.

[0076] In this example, the heating area 5 can be ring-shaped, which can heat the user's breasts in a ring shape to promote milk secretion.

[0077] In specific applications, the heating element 221 can be ring-shaped and can be installed as a whole on the milk suction flange 21. In some embodiments, the heating element 221 can also be rectangular, semi-circular, etc.

[0078] In this embodiment, an annular heating element 221 is used, and the annular heating area 5 surrounds and fits the user's breast, improving the user experience. In this embodiment, the center of the milk suction flange assembly 2 is the milk inlet 6. The heating element 221 is annular and has one piece. The inner ring of the heating element 221 can be close to the milk inlet 6, and the diameter of the inner ring of the heating element 221 can be a suitable range such as 40mm or 44mm. The outer ring of the heating element 221 can be close to the outer peripheral edge of the milk suction flange 21.

[0079] In some embodiments, at least two heating elements 221 may be provided, and at least two heating elements 221 may be arranged in parallel, and each heating element 221 may be independently temperature controlled.

[0080] In this way, multiple heating elements 221 can be independently temperature-controlled, allowing for independent temperature control of different areas of the user's breast to further improve the user experience. For example, the breast pump flange assembly 2 has two annular heating areas 5, each with an annular heating element 221; the first heating element 221 is located near the outer edge of the breast pump flange 21, and the second heating element 221 is located within the inner ring of the first heating element 221 and near the center of the breast pump flange 21; thus, the heating area 5 corresponding to the first heating element 221 can conform to the outer periphery of the user's breast, and the heating area 5 corresponding to the second heating element 221 can be closer to the user's nipple area. The two heating elements 221 can be independently temperature-controlled to further improve the user experience.

[0081] Please see Figure 6a , Figure 6b and Figure 11 In this embodiment, the heating element 221 is trumpet-shaped and fits into the milk suction flange 21, while the heating area 5 on the milk suction flange 21 is annular.

[0082] In some embodiments, the breast pump flange 21 includes a flange body 210 and a cover 212, the cover 212 being connected to the flange body 210, and the heating element 221 being at least partially sandwiched between the flange body 210 and the cover 212. In this embodiment, the heating element 221 is sandwiched between the flange body 210 and the cover 212, forming an embedded structure.

[0083] Please see Figure 6a , Figure 6b, Figure 7 and Figure 9 In this embodiment, the cover 212 is disposed on the flange body 210 and covers the heating element 221 to encapsulate the heating element 221. In this embodiment, the heating element 221 is sealed between the cover 212 and the flange body 210 to prevent the heating element 221 from being damaged accidentally.

[0084] Specifically, the cover 212 can be a plastic part with a certain degree of hardness, and the flange body 210 can be a soft plastic part.

[0085] In some embodiments, when multiple temperature sensors 222 are provided, at least some of the temperature sensors 222 are sandwiched between the flange body 210 and the cover body 212, making the temperature sensors 222 more difficult to be damaged by external forces.

[0086] In some embodiments, the temperature sensor 222 is disposed on the heating element 221, and the temperature sensor 222 can more directly sense the temperature on the heating element 221. When the heating element 221 is completely sandwiched between the flange body 210 and the cover 212, the temperature sensor 222 is also sandwiched between the flange body 210 and the cover 212.

[0087] In some embodiments, the temperature sensor 222 is at least partially embedded in the flange body 210, so that the temperature sensor 222 can more accurately sense the temperature of the flange body 210 on the side closer to the human body.

[0088] Please see Figure 6a , Figure 6b , Figure 9 and Figure 10 The temperature sensor 222 is sandwiched between the cover 212 and the flange body 210, making it less susceptible to interference or damage from external forces. The temperature sensor 222 is embedded in the flange body 210, allowing for more accurate temperature sensing on the side of the flange body 210 closer to the human body.

[0089] Please see Figure 1 , Figure 2 and Figure 8The connection structure 3 includes a plug-in hole 11 disposed in the main unit module 1, and the milk suction flange assembly 2 has a milk inlet 6. A plug-in ring 20, which can be inserted into the plug-in hole 11, is disposed at the milk inlet 6. The connection structure 3 includes the plug-in ring 20. In specific applications, the main unit module 1 may include an air pump (not shown in the figure) and a milk storage container (not shown in the figure). The main unit module 1 has a milk suction channel, which communicates with the plug-in hole 11, and the milk storage container is connected to the milk suction channel. When the milk suction flange assembly 2 is connected to the plug-in hole 11, the milk inlet 6 is connected to the milk suction channel. The air pump is used to generate negative pressure in the milk suction channel. When the breast pump 100 is in use, the air pump can generate negative pressure in the milk suction channel of the breast pump 100, allowing milk to enter the milk storage container through the milk suction channel.

[0090] Furthermore, in the plug ring 20 and the plug hole 11, which are part of the connection structure 3, the outer side of the plug ring 20 may have an exposed conductive element to facilitate electrical connection between the plug ring 20 and the plug hole 11; the inner side of the plug hole 11 may also have an exposed conductive element to facilitate electrical connection between the plug hole 11 and the plug ring 20. This facilitates the formation of a circuit between the plug ring 20 and the plug hole 11, thereby electrically connecting the main unit module 1 and the milk pumping flange assembly 2.

[0091] In some embodiments, the plug ring 20 and the plug hole 11 are respectively provided with three sets of electrode connectors, wherein the first set is used to connect to the positive electrode of the heating component 22; the second set is used to connect to the positive electrode of the temperature sensor 222; and the third set is used to connect to both the negative electrode of the heating component 22 and the negative electrode of the temperature sensor 222. In this way, the heating element 221 and the temperature sensor 222 can be electrically connected to the host module 1 through the three electrode interfaces, and the voltage of the circuits connected to the heating element 221 and the temperature sensor 222 can be set separately.

[0092] Alternatively, the insertion ring 20 and the insertion hole 11 are respectively provided with four sets of electrode connectors, two of which are used to connect to the positive and negative terminals of the heating component 22; the other two are used to connect to the positive and negative terminals of the temperature sensor 222. The voltages of the circuits connected to the heating element 221 and the temperature sensor 222 can be set separately.

[0093] In some embodiments, the milk suction flange assembly 2 includes a fixing connection assembly 23, which is used to fix the heating element 221 to the cover 212. The fixing connection assembly 23 makes the relative position of the heating element 221 and the cover 212 more stable.

[0094] Understandably, the flange body 210 is generally made of soft rubber (silicone). In some cases, during the manufacturing of the breast pump flange assembly 2, the cover 212 and the heating element 221 can be pre-assembled into an assembly using the fixed connection assembly 23. This assembly is then placed in a mold, and the flange body 210 connected to the assembly is formed by injecting glue into the mold, thus obtaining the breast pump flange assembly 2. In this case, before the flange body 210 is molded by injecting glue onto the cover 212 and the heating element 221, the cover 212 and the heating element 221 are fixed in relative position by the engagement of the positioning protrusion 2121 and the positioning hole 2211. During the process of molding the flange body 210 by injecting glue, unnecessary displacement between the heating element 221 and the cover 212 is less likely to occur.

[0095] In some embodiments, the fixed connection assembly 23 includes a first connector 231 and a second connector 232; the first connector 231 and the second connector 232 can be connected by threads to clamp the heating element 221 and the cover 212.

[0096] Please see Figure 9 and Figure 10 In this embodiment, the heating element 221 is sandwiched between the flange body 210 and the cover 212. The first connector 231 has a threaded hole at the first end of the cover 212. The second connector 232 passes through the preset hole of the heating element 221 and is screwed into the threaded hole of the first connector 231, so that the first connector 231 and the second connector 232 are connected by threads. The first connector 231 and the second connector 232 each have a protruding edge 233. The protruding edge 233 is at both ends of the fixed connection assembly 23 and fastens the cover 212 and the heating element 221.

[0097] Please see Figure 9 and Figure 10 The insertion ring 20 includes the heating element 221 and the cover 212 arranged from the inside to the outside, and the fixed connection assembly 23 is radially connected to the insertion ring 20.

[0098] The insertion ring 20 of the milk pump flange assembly 2 is inserted into the insertion hole 11 at the main unit module 1. The inner side of the insertion ring 20 is the milk inlet 6 of the milk pump flange assembly 2. The cover 212 can serve as the outermost layer of the insertion ring 20. The cover 212 is fitted with the heating element 221 and connected to the flange body 210. The heating element 221 at the insertion ring 20 and the cover 212 are clamped by the fixing connection assembly 23.

[0099] In some embodiments, the fixed connection component 23 is a conductive element and contacts the conductive portion of the heating element 221, and at least part of the first end of the fixed connection component 23 is exposed outside the insertion ring 20; a conductive snap-fit ​​component 31 is provided on the inner side of the insertion hole 11, the conductive snap-fit ​​component 31 is a conductive element, the conductive snap-fit ​​component 31 is used to snap with the first end of the fixed connection component 23, and realize electrical connection. The connection structure 3 also includes the fixed connection component 23 and the conductive snap-fit ​​component 31; the host module 1 is provided with a circuit board and / or a power module, and the conductive snap-fit ​​component 31 is electrically connected to the circuit board and / or the power module.

[0100] In specific applications, a conductive snap-fit ​​component 31 is provided on the inner side of the insertion hole 11. The conductive snap-fit ​​component 31 is conductive and electrically connected to the main unit module 1. The fixed connection component 23 is exposed on the outer side of the insertion ring 20, and the first end of the fixed connection component 23 snaps into the conductive snap-fit ​​component 31 on the inner side of the insertion hole 11. Thus, the conductive snap-fit ​​component 31 snaps into the fixed connection component 23 to fix the assembly of the milk suction flange assembly 2 on the main unit module 1. At the same time, both the fixed connection component 23 and the conductive snap-fit ​​component 31 are conductive. The fixed connection component 23 is conductive with the conductive snap-fit ​​component 31 and simultaneously contacts the heating element 221. Thus, the main unit module 1, the conductive snap-fit ​​component 31, the fixed connection component 23, and the heating element 221 can form a circuit. The main unit module 1 is provided with a circuit board and / or a power module. Therefore, when the milk suction flange assembly 2 and the main unit module 1 are snapped into place, the electrical connection between the heating element 221 and the main unit module 1 is also completed.

[0101] Understandably, the main unit module 1 can be equipped with a battery as a power supply module.

[0102] In some embodiments, the conductive snap-fit ​​component 31 is a bead positioning structure, and the first end of the fixed connection component 23 is provided with a concave surface 32 corresponding to the conductive snap-fit ​​component 31. The concave surface 32 may be a spherical concave surface.

[0103] In this embodiment, the conductive snap-fit ​​component 31 can be a glass bead positioning structure, comprising a connecting cylinder, a glass bead, and an elastic element. The connecting cylinder has an inner cavity for mounting the elastic element, and the front end of the connecting cylinder has a mounting hole for the glass bead to partially protrude. The elastic element can be a spring, one end of which abuts against the glass bead, causing the glass bead to elastically abut against the mounting hole, and the other end of the elastic element abuts against the rear end of the connecting cylinder. The connecting cylinder can be embedded and installed inside the insertion hole 11. Under the action of the elastic element, the glass bead partially protrudes from the inside of the insertion hole 11. When the user inserts the insertion ring 20 into the insertion hole 11, the glass bead contacts the insertion ring 20 and is pushed back by the force of the insertion ring 20, while the elastic element is further compressed, and the insertion ring 20 continues to be inserted into the insertion hole 11. When the insertion ring 20 reaches the preset position, the glass bead corresponds to the corresponding spherical concave surface 32 on the fixed connection component 23. Under the reset action of the elastic element, the glass bead extends into the concave surface 32, allowing the milk suction flange component 2 to dock with the main module 1. When disassembly is required, simply pull out the milk suction flange assembly 2. That is, the plug ring 20 causes the glass bead to retract under force, and the plug ring 20 exits the plug hole 11. Under the reset action of the elastic element, the glass bead protrudes from the inside of the plug hole 11.

[0104] Understandably, the elastic element can be a conductive metal spring, and the glass bead can be a metal glass bead made of a highly conductive metal material (such as stainless steel) in order to achieve an electrical connection to the host module 1.

[0105] It is understandable that the conductive snap-fit ​​component 31 can also be an elastic snap-fit ​​component. When the insertion ring 20 is inserted, the conductive snap-fit ​​component 31 is pushed back by force. When the concave surface on the fixed connection component 23 corresponds to the convex direction of the conductive snap-fit ​​component 31, the conductive snap-fit ​​component 31 pops out again.

[0106] Please see Figure 11 and Figure 12 In this embodiment, the fixed connection component 23 and the conductive snap-fit ​​component 31 are respectively provided in three sets. The first set is used to connect to the positive electrode of the heating element 221; the second set is used to connect to the positive electrode of the temperature sensor 222; and the third set is used to connect to both the negative electrode of the heating element 221 and the negative electrode of the temperature sensor 222. In this way, it can be ensured that both the heating element 221 and the temperature sensor 222 can be electrically connected to the host module 1 through the corresponding fixed connection component 23 and conductive snap-fit ​​component 31.

[0107] Alternatively, in some other embodiments, the fixed connection component 23 and the conductive snap-fit ​​component 31 are respectively provided in four sets, two of which are used to connect to the positive and negative terminals of the heating element 221; the other two are used to connect to the positive and negative terminals of the temperature sensor 222.

[0108] Please see Figure 2 , Figure 3and Figure 9 In this embodiment, when the milk suction flange assembly 2 is inserted into the insertion hole 11, the milk suction flange assembly 2 passes through the insertion hole 11, and a retaining edge 211 is provided at one end of the insertion hole 11. The retaining edge 211 can abut against the main unit module 1 to seal the gap between the milk suction flange assembly 2 and the insertion hole 11.

[0109] In some embodiments, a misalignment prevention structure 4 with a concave-convex fit is provided between the insertion ring 20 and the insertion hole 11, so that each fixed connection component 23 is correspondingly connected to each preset conductive snap-fit ​​component 31.

[0110] Please see Figure 8 To facilitate the correct connection between the milk suction flange assembly 2 and the main unit module 1, and to ensure that the fixed connection structure 3 and the conductive snap-fit ​​component 31 are properly engaged, a misalignment prevention structure 4 with a convex-concave fit can be provided to avoid incorrect connection methods.

[0111] In this embodiment, the anti-misalignment structure 4 includes an assembly groove 41 and an assembly protrusion 42; in the insertion ring 20 and the insertion hole 11, one has the assembly groove 41 and the other has the assembly protrusion 42.

[0112] Please see Figure 8 , Figure 9 and Figure 12 In this embodiment, the insertion hole 11 has an assembly groove 41, and the insertion ring 20 has an assembly protrusion 42, so that the user can only assemble the milk suction flange assembly 2 and the main unit module 1 in the preset correct manner. At the same time, a fixed connection component 23 is exposed on the end face of the assembly protrusion 42, and the corresponding conductive snap-fit ​​component 31 is disposed in the corresponding position of the assembly groove 41 inside the insertion hole 11.

[0113] Please see Figure 6a , Figure 6b and Figure 7In this embodiment, the cover 212 has a positioning protrusion 2121 on the side facing the flange body 210, and the heating element 221 has a positioning hole 2211. The positioning protrusion 2121 and the positioning hole 2211 are fitted together, and the cover 212 and the heating element 221 are fixed in relative position by the insertion and engagement of the positioning protrusion 2121 and the positioning hole 2211 to facilitate assembly. Meanwhile, the flange body 210 has a mounting groove 213 on the side away from the user's breast, which is relatively close to the nipple inlet 6. The cover 212 is trumpet-shaped and installed in the mounting groove 213. The cover 212 has a flange 2122, which is located at the edge away from the center of the cover 212 and protrudes towards the flange body 210. The flange 2122 is snapped into the flange body 210, resulting in a stable connection between the cover 212 and the flange body 210. Generally, the flange body 210 is designed in a trumpet shape to fit the shape of the user's breast. In this embodiment, the cover 212 of the breast pump 100 is also designed in a trumpet shape to match the shape of the flange body 210, making the structure of the breast pump flange 21 reasonable and its appearance neat and beautiful. Furthermore, the cover 212 is installed in the mounting groove 213, and the edge of the cover 212 has a flange 2122 protruding towards the flange body 210. The flange 2122 is fitted into the flange body 210 to improve structural reliability. In specific applications, the main body of the heating element 221 can be trumpet-shaped, with one side abutting the inner side of the cover 212 and the other side abutting the flange body 210.

[0114] In some embodiments, the host module 1 may be equipped with a display screen or have an external display screen connected to it. The display screen is electrically connected to the temperature sensor 222. In some optional embodiments, the display screen may display the temperature monitored by the temperature sensor 222.

[0115] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
