[0002] With the development of society and the improvement of people's living standards, more and more mothers begin to pay attention to postpartum care and the quality of infant feeding. However, in the actual lactation process, many mothers will encounter nipple pain, breast congestion and other problems when breastfeeding, which not only affects the breastfeeding experience, but also may lead to decreased milk production. Although traditional breast pumps can help solve these problems to some extent, there are still deficiencies in promoting milk secretion and relieving breast discomfort. In recent years, research has found that moderate heat application helps to dilate the lactiferous ducts, promote blood circulation, thereby effectively relieving breast distending pain, increasing milk production, and effectively preventing and treating breast congestion. Therefore, nursing products with heat application function have appeared on the market, such as heat pads, warmies, etc. These products can be used before breastfeeding to achieve the effect of preheating the breasts. However, the heat application effect of such products is often not uniform, and additional operation steps are required, making it difficult to synchronize with the breast pumping process.

[0003] Therefore, it is necessary to develop a heating assembly and a breast pump that can achieve simultaneous heat application during the breastfeeding process to improve the breastfeeding experience and increase milk production. SUMMARY

At least two of the connecting ends, the connecting housing and the milk suction part form an installation area for installing the transparent assembly. The heating device is also provided with a clearance area for the milk suction part to extend into.

[0010] Furthermore, in the heating assembly described in the solution, the transparent assembly has a mating hole located in the center and cooperating with the milk-suction part, and a mating groove located near the heating device and cooperating with the connecting end. There are multiple mating grooves. The mounting area is arranged in a ring shape. The inner diameter of the ring of the mounting area is S1. The distance from the center of the milk-suction part to the connecting housing is S2. The proportion of S1 to S2 is between one-third and three-quarters.

[0029] Example 1:

[0030] Please see Figures 1 to 6 The present invention proposes a heating component for a breast pump. The heating component includes a fitting component 1 that fits against the breast, and a heating device 2 connected to the fitting component 1. The fitting component 1 has a cavity into which the breast can be inserted and a transparent area near the outer periphery of the breast. The heating device 2 emits heat to the transparent area so that the heat is transferred to the breast through the transparent area.

[0031] This invention enables simultaneous hot compress during breastfeeding by incorporating a heating device on the bonding component. This feature not only helps dilate mammary ducts and promote blood circulation, but also effectively relieves breast engorgement, increases milk production, and effectively prevents and treats breast blockage, thereby enhancing the breastfeeding experience and milk production. Furthermore, when the heating device uses infrared radiation, the transparent area on the bonding component ensures that the radiant heat released by the heating device can penetrate the transparent area and act on the breast more efficiently and evenly, further enhancing the hot compress effect.

[0032] Furthermore, such as Figures 1 to 6 A heating assembly is shown, wherein the heating device 2 includes a circuit board 21 and a heating element 22 located on the circuit board 21. The circuit board 21 is connected to the bonding assembly 1, and the heating element 22 faces the transparent area.

[0033] This invention features a heating element 22 mounted on a circuit board 21, with the circuit board 21 directly connected to the bonding assembly 1. This configuration not only ensures that the heat emitted by the heating element 22 is accurately applied to the transparent area, but also simplifies the overall design of the heating assembly, making the heating device 2 more compact and stable, and easier to manufacture and maintain. Furthermore, the fact that the heating element 22 is positioned directly opposite the transparent area ensures that radiant heat is efficiently transferred to the breast through the transparent area, thereby effectively promoting the expansion of mammary ducts and blood circulation, and alleviating symptoms of breast swelling and pain and breast blockage.

[0034] Furthermore, such as Figures 1 to 6 The heating assembly shown is provided with multiple heating elements 22, which are arranged evenly around the outer edge of the circuit board 21 and circumferentially along the circuit board 21. The heating elements 22 are infrared lamp beads.

[0035] This invention utilizes multiple heating elements 22 arranged along the outer edge of a circuit board 21, evenly distributed around the circumference of the circuit board 21. This arrangement enables comprehensive and uniform heat application to the peripheral area of ​​the breast, avoiding localized overheating and improving user comfort and safety. Furthermore, the heating elements 22 employ infrared lamps for heating via thermal radiation. This design allows heat to quickly penetrate the skin surface and directly act on deep tissues, promoting blood circulation and mammary duct dilation, thereby more effectively relieving breast swelling and pain, and milk duct blockage. Furthermore, the infrared lamps heat the breast through their transparent areas, allowing heat to penetrate evenly and reach the breast, achieving optimal heat application and further promoting milk secretion and relieving breast discomfort. Finally, this design avoids the risk of burns from contact heating.

[0036] Furthermore, such as Figures 1 to 6 A heating assembly is shown, wherein the bonding assembly 1 includes a bonding housing 11 and a transparent assembly 12 connected to the bonding housing 11, and the transparent area is partially or entirely located on the transparent assembly 12.

[0037] This invention, by setting a transparent component 12 and forming a transparent area within it, allows users to observe the operation of the infrared lamp beads at any time and take timely measures when the heating device 2 malfunctions. Furthermore, the transparent component 12 not only effectively prevents the breast from directly contacting the heating device 2, avoiding the risk of burns caused by direct contact, but also does not affect the heating effect of the heating device 2. This ensures that the heat emitted by the infrared lamp beads can be evenly transferred to the breast through the transparent component 12, guaranteeing the uniformity and effectiveness of the hot compress.

[0038] Furthermore, such as Figures 1 to 6The heating assembly shown includes a fitting housing 11 having a milk suction part 111, a connecting housing 112 located outside the milk suction part 111 and connected to the milk suction part 111, and a plurality of connecting ends 113 connecting the connecting housing 112 and the milk suction part 111. At least two of the connecting ends 113, the connecting housing 112, and the milk suction part 111 form a mounting area 114 for mounting the transparent assembly 12. The heating device 2 also has a clearance area 23 for the milk suction part 111 to extend into.

[0039] In this invention, the milk-suction part 111 is connected to the connecting housing 112 via the connecting end 113 and is integrally formed. This design not only ensures the stability and strength between the milk-suction part 111 and the connecting housing 112, but also simplifies the overall structure, thereby improving manufacturing efficiency and reliability. Furthermore, the installation area 114 allows the transparent component 12 to be firmly fixed to the housing 11, ensuring the stability of the transparent component 12 during use. Furthermore, the clearance area 23 ensures that the milk-suction part 111 can smoothly extend into the heating device 2, thereby bringing the heating device closer to the breast, reducing heat loss to a certain extent, and realizing the simultaneous expression of milk and heat application, improving the efficiency and comfort of breastfeeding.

[0040] Furthermore, such as Figures 1 to 6 The heating assembly shown has a transparent component 12 with a mating hole 121 located in the center and cooperating with the milk suction part 111, and a mating groove 122 located near the heating device 2 and cooperating with the connecting end 113. The mating groove 122 has multiple grooves. The mounting area 114 is arranged in a ring shape with an inner diameter of S1. The distance from the center of the milk suction part 111 to the connecting housing 112 is S2. The proportion of S1 to S2 is between one-third and three-quarters. The transparent component 12 is arranged in a trumpet shape.

[0041] This invention features a mating hole 121 located in the center of the transparent component 12 that mates with the milk-suction part 111, and a mating groove 122 located near the heating device 2 that mates with the connecting end 113. This arrangement not only ensures a tight fit between the transparent component 12 and the fitting housing 11, but also provides good sealing and stability. Furthermore, the mounting area 114 is annular, with its annular inner diameter S1 being in a ratio between one-third and three-quarters of the distance S2 from the center of the milk-suction part 111 to the connecting housing 112. This arrangement ensures that the transparent component 12 has sufficient mounting space to effectively cover most of the breast area, while also ensuring that the milk-suction part 111 does not interfere with the milk-suction part's ability to... The breast absorbs liquid normally, thus ensuring the uniformity of the heat therapy effect. Furthermore, if S1 accounts for more than three-quarters of S2, the installation space for the transparent component 12 will be too large, which will reduce the space occupied by the milk suction part 111 and thus affect the liquid absorption effect. If S1 accounts for less than one-third of S2, the installation space for the transparent component 12 will be too small, which will not only affect the installation and stability of the transparent component 12, but also reduce the heating area, thus affecting the heat therapy effect. Furthermore, the transparent component 12 is flared in shape, which is ergonomic and can mimic the shape of the breast, so that the heat can be distributed more evenly on the surface of the breast, further optimizing the heat therapy effect and improving the user's comfort.

[0042] Furthermore, such as Figures 1 to 6 A heating assembly is shown, wherein the fitted housing 11 and the transparent component 12 are integrally molded.

[0043] This invention uses a one-piece molding process to manufacture the fitted shell 11 and the transparent component 12. This not only simplifies the manufacturing process and reduces production costs, but also improves the stability and sealing of the overall structure. Furthermore, the one-piece molding structure avoids the problems of loosening and poor sealing that may be caused by repeated assembly.

[0044] Furthermore, such as Figures 1 to 6 The heating assembly shown has a circuit board 21 with a connection hole 211, and a fixing end 115 extending from the bonding housing 11 toward the circuit board 21. The fixing end 115 has a fixing hole 1151. The connection hole 211 and the fixing hole 1151 are connected to each other so that the heating device 2 is connected to the bonding assembly 1.

[0045] This invention features a connecting hole 211 on the circuit board 21 and a fixed end 115 extending from the fitting housing 11 toward the circuit board 21. The fixed end 115 has a fixing hole 1151. The connection hole 211 and the fixing hole 1151 work together to connect the heating device 2 with the fitting component 1. This design not only ensures a stable connection between the heating device 2 and the fitting component 1, improving the overall stability and reliability of the structure, but also simplifies the assembly process, enabling quick installation and disassembly of the heating device 2 and the fitting component 1, facilitating maintenance and component replacement. Furthermore, the engagement of the extended fixed end 115 with the circuit board 21 ensures that the infrared lamp bead and the transparent component 12 maintain an appropriate distance, ensuring that heat is evenly transferred to the breast, while avoiding poor heat therapy effects or safety hazards caused by excessively close or far distances.

[0046] Furthermore, such as Figures 1 to 6 The heating assembly shown includes a milk suction unit 111 further comprising a milk suction channel 1111 into which the breast extends, and an inner liner 1112 extending into the milk suction channel 1111, wherein the inner liner 1112 is partially or completely in contact with the inner wall of the milk suction channel 1111.

[0047] This invention provides an inner liner 1112 on the inner wall of the milk suction channel 1111. In this embodiment, the inner liner 1112 is made of silicone, which prevents the breast from making hard contact with the milk suction part 111, thereby increasing user comfort. Furthermore, the inner liner 1112 also increases the seal between the milk suction part 111 and the breast, ensuring a negative pressure effect during milk suction, thus improving milk suction efficiency. Furthermore, the inner liner 1112 partially or completely abuts against the inner wall of the milk suction channel 1111 in this embodiment. The inner liner 1112 is completely abutted against the inner wall of the milk suction channel 1111, which means that the inner liner 1112 is completely located in the milk suction channel 1111. This arrangement further improves the sealing between the inner liner 1112 and the milk suction channel 1111. In some other embodiments, the inner liner 1112 is partially abutted against the inner wall of the milk suction channel 1111, which means that a part of the inner liner 1112 can extend into the transparent component 12 and be seamlessly connected to the transparent component 12. This arrangement avoids the problem of insufficient heating effect due to gaps.

[0048] This embodiment proposes a heating component that combines heat therapy and milk expression functions, primarily to improve the user experience during breastfeeding or milk expression, promote milk secretion, and alleviate symptoms of breast engorgement and blocked milk ducts. The heating component mainly consists of a bonding component 1 and a heating device 2, wherein the bonding component 1 has a milk expression function; the two work together to ensure the simultaneous implementation of heat therapy and milk expression functions.

[0049] The heating device 2 consists of a circuit board 21 and a heating element 22 mounted on the circuit board 21. The heating element 22 uses multiple infrared LEDs, which are evenly arranged along the edge of the circuit board 21 and directly aligned with the transparent area on the transparent component 12 located in the bonding assembly 1. The transparent component 12 is located on the outer periphery of the breast, serving not only as an observation window allowing the user to observe the working status of the infrared LEDs but also protecting the user from direct contact with them. This embodiment utilizes the thermal radiation function of the infrared LEDs to achieve uniform heating of the breast, effectively avoiding the risk of localized overheating. Furthermore, the transparent component 12 adopts a trumpet shape, making the heating assembly more ergonomic and conforming better to the natural shape of the breast, further improving the heating effect and user experience.

[0050] In addition, a milk suction part 111 is provided in the fitting shell 11, and the milk suction part 111 is provided with a milk suction channel 1111. A silicone liner 1112 is installed inside the milk suction channel 1111. The liner 1112 is completely in contact with the inner wall of the milk suction channel 1111, which not only increases the user's comfort, but also improves the negative pressure effect during the milk suction process, ensuring efficient milk extraction.

[0051] Furthermore, to ensure that the transparent component 12 can be securely installed on the fitting housing 11, the milk-pumping part 111 is connected to the connecting housing 112 via the connecting end 113, together forming a mounting area 114 for installing the transparent component 12. The mounting area 114 is annular, with an inner diameter of S1. The inner diameter S1 of the mounting area 114 accounts for seven-fifteenths of the distance S2 from the center of the milk-pumping part 111 to the connecting housing 112. The transparent component 12 is fixed in the mounting area 114 and integrally formed with the fitting housing 11, ensuring structural stability and product sealing. At the same time, a clearance area 23 is also provided in the heating device 2, allowing the milk-pumping part 111 to extend into it, so that the heating device 2 can be closer to the breast, thereby reducing heat loss and improving the heat therapy effect.

[0052] During installation, the heating device 2 and the bonding component 1 are tightly connected by aligning the connection hole 211 on the circuit board 21 of the heating device 2 with the fixing hole 1151 on the fixing end 115 of the bonding housing 11. This arrangement not only simplifies the assembly process but also ensures the stability between the heating device 2 and the bonding component 1. Simultaneously, it maintains an appropriate distance between the infrared LED and the transparent component 12, facilitating more efficient heat transfer to the breast and ensuring the uniformity and effectiveness of the heat therapy.

[0053] Example 2:

[0054] Please see Figures 1 to 8The present invention also proposes a breast pump, which further includes a drive assembly 3 and a milk storage container 4. The heating assembly is connected to the drive assembly 3 and the milk storage container 4 respectively. The function of the drive assembly 8 is to provide the required suction for the milk suction channel 1111 on the heating assembly. The function of the milk storage container 7 is to concentrate the milk in the milk storage container 7 for storage after the milk is sucked into the milk suction channel 1111.

[0055] The breast pump of this invention features a heating component with a transparent area in the contact component 1 that fits against the breast. A heating device 2 radiates heat to this transparent area, providing simultaneous heat therapy during breastfeeding or pumping. This design overcomes the limitations of traditional breast pumps that cannot provide heat therapy while pumping, improving both breastfeeding comfort and efficiency. Furthermore, the drive component 8 provides the necessary suction to the milk suction channel 1111 on the heating component, ensuring smooth milk flow from the breast into the channel 1111. This also eliminates the need for an external power source, allowing for convenient use anytime, anywhere. Moreover, the milk storage container 7, connected to the milk suction channel 1111, ensures that the milk is collected and stored after being drawn into the channel. This facilitates milk collection and storage, prevents spillage and waste, and ensures hygiene and cleanliness during the pumping process. Furthermore, by using the heating component in conjunction with the drive component 3 and the milk storage container 4, simultaneous milk expression and heat application are achieved, improving the overall breastfeeding effect. The heat application effectively promotes the expansion of mammary ducts and blood circulation, enhances milk secretion, and alleviates symptoms of breast engorgement and milk blockage. At the same time, the stable suction provided by the drive component 3 and the centralized storage function of the milk storage container 4 ensure efficient collection and storage of milk, further optimizing the breastfeeding experience. In some other embodiments, milk expression can be achieved by manually pressing the airbag without the need for the drive component 3.

[0056] Example 3:

[0057] The difference between this embodiment and Embodiment 1 is that the annular inner diameter S1 of the installation area 114 accounts for one-third of the distance S2 from the center of the milk suction part 111 to the connecting shell 112.

[0058] Example 4:

[0059] The difference between this embodiment and Embodiment 1 is that the annular inner diameter S1 of the installation area 114 accounts for three-quarters of the distance S2 from the center of the milk suction part 111 to the connecting shell 112.
