[0002] Breast pumps are a common auxiliary tool for breastfeeding women, widely used in the breastfeeding process, especially suitable for situations where direct breastfeeding is not possible or where breast milk needs to be stored. Existing breast pumps typically consist of a bell-shaped shield to conform to the breast and a main unit to generate negative pressure to express milk. To improve the comfort and efficiency of pumping, some breast pumps incorporate a heating element in the bell-shaped shield, which locally heats the breast to promote milk flow and milk secretion, thus enhancing user comfort.

[0003] In existing technologies, heating components typically include a heating film, connecting terminals, and mating terminals. The connecting terminals and heating film are located on the speaker cover, while the mating terminals are located on the main unit. The main unit can provide power to the heating film located on the speaker cover through the electrical connection between the connecting terminals and the mating terminals. However, during user use, the speaker cover may be squeezed and deformed. This deformation will be conducted to the connecting terminals, thereby affecting the stability of the connection between them and the mating terminals on the main unit, leading to poor contact, power failure, or even failure of the heating function.

[0024] Example 1

[0025] Please see Figures 1 to 4 The heating structure of a breast pump shown includes a horn cover 1 that contacts the breast and a main unit assembly 2 connected to the horn cover 1. The horn cover 1 is provided with a heating component 3. The heating component 3 includes a heating film 31 connected to the horn cover 1, a wire 32 connected to the heating film 31, and a connecting terminal 33 connected to the wire 32. The main unit assembly 2 is provided with a mating terminal 21. The connecting terminal 33 is mated with the mating terminal 21 to electrically connect the heating component 3 to the main unit assembly 2.

[0026] In this invention, the horn cover 1 is the part of the breast pump that directly contacts the breast. Its main function is to conform to the breast, create a negative pressure space for milk expression, and provide a mounting base for the heating component. The horn cover 1 is typically made of soft, skin-friendly, and high-temperature resistant materials to ensure comfort and safety. The main unit 2 is the core part of the breast pump, mainly including a drive motor, a negative pressure pump, a control circuit, and a power module. It is responsible for generating the negative pressure required for milk expression and controlling the operation of the heating component 3. The main unit 2 is provided with a mating terminal 21 for connecting to the connection terminal 33 of the heating component 3, realizing the power supply and control of the heating component 3, enabling the heating component 3 to start its heating function under set conditions. The heating component 3 includes three components: a heating film 31, a wire 32, and a connection terminal 33. The heating film 31 is the heating element in the heating component 3, which is located on the... The speaker cover 1 is used for local heating of the breast. The wire 32 is used to connect the heating film 31 and the connecting terminal 33, transmitting the electrical energy provided by the main unit 2 to the heating film 31 to realize the heating function. The connecting terminal 33 is used to plug and unplug into the mating terminal 21 on the main unit 2 to realize the electrical connection between the heating component 3 and the main unit 2. In summary, by setting the connecting wire 32 between the connecting terminal 33 and the heating film 31, the speaker cover 1 can effectively buffer the deformation when squeezed or deformed during use, so that such deformation will not be directly transmitted to the connecting terminal, causing the connection between the connecting terminal 33 and the mating terminal 21 to become loose. This effectively improves the connection stability and reliability of the connection between the connecting terminal 33 and the mating terminal 21, and avoids problems such as poor contact, power failure, or even failure of heating function caused by the loose connection between the connecting terminal 33 and the mating terminal 21.

[0027] Furthermore, the heating film 31 can be a metal heating film, or it can be a new type of heating material such as flexible PTC, carbon fiber heating film, or carbon-based ink heating film, which has the advantages of rapid heating, controllable temperature, and uniform heating.

[0028] Furthermore, the main unit 2 is provided with a guide groove 22, the mating terminal 21 is located in the guide groove 22, the heating component 3 is provided with a connecting part 34 connected to the wire 32, the connecting terminal 33 is located in the connecting part 34, and the connecting part 34 is mated with the guide groove 22 to ensure a stable connection between the connecting terminal 33 and the mating terminal 21.

[0029] In this utility model, the main unit 2 is provided with a guide groove 22, the heating component 3 is provided with a connecting part 34 connected to the wire 32, and the mating terminal 21 and the connecting terminal 33 are respectively provided in the guide groove 22 and the connecting part 34. The shape of the guide groove 22 matches the shape of the connecting part 34. The guide groove 22 can guide the connecting part 34 to be accurately inserted, ensuring the alignment and stable connection between the connecting terminal 33 and the mating terminal 21, avoiding terminal misalignment, poor contact or difficulty in insertion and removal caused by improper manual insertion and removal, and effectively improving the convenience of user operation and connection reliability.

[0030] Furthermore, the heating structure of the breast pump also includes a magnetic suction assembly 4, which includes a first magnetic suction member 41 disposed in the guide groove 22 and a second magnetic suction member 42 disposed in the connecting part 34. The first magnetic suction member 41 and the second magnetic suction member 42 are magnetically attracted to each other to ensure that the connecting part 34 is firmly connected to the guide groove 22.

[0031] In this invention, the heating structure of the breast pump further includes a magnetic suction assembly 4, which includes a first magnetic suction element 41 and a second magnetic suction element 42. The first magnetic suction element 41 is disposed in the guide groove 22 and forms a magnetic attraction with the second magnetic suction element 42 disposed in the connecting part 34. The first magnetic suction element 41 and the second magnetic suction element 42 can be magnets, magnetic rings or embedded magnetic elements. Through the magnetic attraction between the first magnetic suction element 41 and the second magnetic suction element 42, the connecting part 34 can be firmly attracted after being inserted into the guide groove 22, avoiding loosening or detachment of the connection due to vibration, movement or accidental contact. Based on the connection between the connecting part 34 and the guide groove 22, the connection stability and reliability are further improved.

[0032] Furthermore, the speaker cover 1 includes a flexible portion 11 located on the side away from the main unit 2, and the heating film 31 is located inside the flexible portion 11, and the heating film 31 is arranged in an arc shape along the extending direction of the flexible portion 11.

[0033] In this invention, the flexible part 11 is located on the side of the speaker cover 1 away from the main unit 2, and is the part of the speaker cover 1 that directly contacts the breast. Preferably, the flexible part is made of a soft, skin-friendly, and deformable material such as silicone, which can conform to breasts of different sizes and shapes, thereby improving user comfort. Furthermore, the heating film 31 is disposed within the flexible part 11 and arranged in an arc shape along the extension direction of the flexible part 11. This design ensures that the heating film 31 is evenly distributed in the part of the flexible part 11 that contacts the breast, making the heat distribution more uniform, avoiding local overheating or cold spots, thereby improving the heating effect of the heating component and enhancing user comfort.

[0034] Furthermore, the flexible part 11 and the heating film 31 are integrally coated with adhesive.

[0035] In this invention, the flexible part 11 and the heating film 31 are integrally formed by overmolding. The heating film 31 is completely covered inside the flexible part 11, avoiding the risk of loosening, displacement or falling off of the heating film in traditional assembly methods. This improves the structural stability and sealing performance of the heating component 3, preventing liquid infiltration that could lead to short circuits or damage. Furthermore, there are no air gaps between the heating film 31 and the flexible part 11, resulting in a shorter and more efficient heat conduction path. This helps to achieve a more uniform heat distribution, avoiding local overheating or uneven heating, thereby improving the user experience. In addition, from a production perspective, the overmolding process can achieve automated production, reduce manual assembly steps, improve product consistency and yield, and thus reduce manufacturing costs.

[0036] Furthermore, the connecting terminal 33 is a fixed terminal, and the mating terminal 21 is a flexible terminal.

[0037] In this invention, the connecting terminal 33 is a fixed terminal, and the mating terminal 21 is a flexible terminal. The fixed terminal provides a stable conductive contact surface and is typically in the form of a metal sheet, pin, or contact point, possessing good conductivity and structural rigidity. The flexible terminal, on the other hand, uses a spring sheet, elastic probe, or elastic metal contact, etc., and has a certain deformation capability, providing contact pressure during insertion and removal to ensure good conductivity. By designing the connecting terminal 33 as a fixed terminal and the mating terminal 21 as a flexible terminal, assembly errors can be automatically compensated during insertion and removal, enhancing the contact pressure between terminals, improving the stability and reliability of the electrical connection, and avoiding power outages, overheating, or functional failures caused by poor contact, thereby improving the electrical connection stability between the heating component 3 and the main unit component.

[0038] Furthermore, a limiting part 321 is provided at one end of the wire 32 that is connected to the connecting part 34. The outer diameter of the limiting part 321 is larger than the inner diameter of the guide groove 22 to limit the insertion depth of the connecting part 34.

[0039] In this invention, the limiting part 321 is disposed at the end where the wire 32 connects to the connecting part 34. As a physical limiting structure, it prevents the connecting part 34 from being inserted too deeply, avoiding terminal misalignment, structural damage, or abnormal electrical connection caused by excessive insertion. When the connecting part 34 is inserted into the guide groove 22, the limiting part 321 will abut against the entrance of the guide groove 22, preventing the connecting part 34 from being inserted further. This precisely controls the insertion depth, avoids structural damage, and allows the user to perceive the connection status during insertion and removal, improving the controllability and ease of use of the operation.

[0040] Example 2

[0041] This utility model also provides, for example Figures 1 to 4 The heating structure of a breast pump shown includes the heating structure of a breast pump as described above.

[0042] By integrating the aforementioned heating structure, the breast pump evenly heats the breasts during the pumping process, promoting milk flow, relieving breast engorgement, and improving pumping efficiency and user comfort. Furthermore, the heating structure and main unit employ multiple connection methods, including plug-in, magnetic, and guide types, enhancing connection stability and electrical reliability. This reduces heating failures caused by poor contact and allows the heating component to be easily disassembled for cleaning or replacement, thus improving product hygiene and ease of use.

[0043] Example 3

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

[0045] The wire 32 is flat and is disposed on the edge of the speaker cover 1. The wire 32 is connected to the end of the flexible part 11 on the side away from the main unit 2.

[0046] Traditional breast pumps often use circular cables with a round cross-section. While these cables offer good conductivity, they are prone to breakage due to bending fatigue in environments with frequent bending and stretching, affecting the stability of the heating function. In this invention, the wire 32 is flat. Compared to traditional round wires, the flat wire 32 has better flexibility and fatigue resistance, making it suitable for frequent movement and bending scenarios that may occur during breast pump use, thus extending the wire's lifespan. In addition, the flat wire 32 has a certain degree of torsion resistance, which can guide the deformation direction of the wire 32, effectively reducing irregular deformation and minimizing the space occupied by the wire 32 in the product, making the overall structure more compact and aesthetically pleasing. Furthermore, the wire 32 is located at the edge of the speaker cover 1, and it is connected to the end of the flexible part 11 away from the main unit component 2. This design ensures the uniformity of the thickness of the flexible part 11, preventing changes in the local hardness of the flexible part 11 due to the connection between the wire 32 and the middle section of the flexible part 11, reducing the user's foreign body sensation during use, and improving the user experience.

[0047] Example 4

[0048] Based on Example 1, Example 4 also has the following implementation method:

[0049] Please see Figure 2 , Figure 3The heating structure of a breast pump shown has a guide groove 22 located on the side of the main unit 2 near the horn cover 1. The cross-sectional shape of the guide groove 22 is racetrack-shaped, and the shape of the connecting part 34 matches the shape of the guide groove 22.

[0050] In this invention, the guide groove 22 is positioned on the side of the main unit 2 near the speaker cover 1, which facilitates the user's connection of the speaker cover 1 and the connecting part 34 to the main unit 2. Simultaneously, it effectively shortens the length of the wire 32, making the overall structure more compact and preventing the connection structure from affecting the overall portability and comfort of the breast pump. Furthermore, the cross-sectional shape of the guide groove 22 is designed as a racetrack shape, with a straight middle edge and semi-circular ends, giving the guide groove 22 excellent guiding performance. This facilitates the smooth insertion of the connecting part 34 and prevents rotation or misalignment of the connecting part 34 during insertion and removal. Compared to circular or rectangular structures, the racetrack-shaped structure is easier to align during insertion and removal and also has a certain anti-rotation function, ensuring that the connecting terminal 33 and the mating terminal 21 always maintain the correct mating direction. This further improves the insertion and removal guidance, connection stability, and structural compactness between the heating component and the main unit 2.

[0051] Example 5

[0052] The difference between Embodiment 5 and Embodiment 1 is that the connecting terminal 33 is an elastic terminal and the mating terminal 21 is a fixed terminal.

[0053] Example 6

[0054] Example 6, based on Example 1, also has the following implementation method:

[0055] The cross-sectional length direction of the guide groove 22 is the same as that of the cross-sectional length direction of the conductor 32.

[0056] In this invention, the cross-sectional length direction of the guide groove 22 is set to be consistent with the cross-sectional length direction of the wire 32. This means that when the connecting part is inserted into the guide groove 22, the direction of the wire 32 is coordinated with the insertion and removal direction, avoiding bending, twisting or stress concentration caused by misalignment. This helps the wire to maintain a smooth state during insertion and removal, reducing damage to the wire 32 or confusion in the direction of the wire 32 caused by unreasonable structural layout, thereby improving the convenience of insertion and removal operations for users. In summary, by setting the cross-sectional length direction of the guide groove 22 to be consistent with the cross-sectional length direction of the wire 32, the heating component, insertion and removal guidance performance and the stress state of the wire 32 are further optimized.

[0057] Example 7

[0058] The difference between Embodiment 7 and Embodiment 1 is that the flexible part 11, heating film 31, wire 32 and connecting terminal 33 are integrally coated with glue. The integral molding of the flexible part 11, heating film 31, wire 32 and connecting terminal 33 can reduce the number of breast pump parts and facilitate user assembly.
