Description

Technical Field

[0001] This utility model relates to the field of breast pumps, specifically a heated nipple shield structure for a breast pump. Background Technology

[0002] In modern parenting, breast pumps have become an indispensable tool for many breastfeeding mothers. Traditional breast pumps mainly focus on milk extraction, using a simple negative pressure principle to draw milk from the breast. However, when used in low-temperature environments, the cold breast pump cover directly contacts the breast, causing discomfort for mothers. It may even cause breast contraction due to low-temperature stimulation, affecting milk production. Therefore, breast pump covers with heating structures have appeared on the market. These breast pump covers use traditional resistance wires as their heating structure. However, traditional resistance wires have the problem of uneven heating, and there is also a risk of localized overheating leading to burns.

[0003] Therefore, it is necessary to develop a heating bra structure for breast pumps to solve the problem of uneven heating and the risk of burns caused by localized high temperatures, which are common with traditional resistance heating systems. Utility Model Content

[0004] Regarding the aforementioned problems of discomfort and stimulation of breast contraction caused by the cold breast shield contacting the breast when using traditional breast pumps in low-temperature environments, the technical solution adopted by this utility model to solve these problems is as follows:

[0005] A heated breast shield structure for a breast pump includes a breast shield and a heating component connected to the breast shield. The breast shield includes a fitting portion that conforms to the breast area. The heating component includes a conductive heating coating disposed on the fitting portion. The conductive heating coating forms a heating zone by covering the side of the fitting portion away from the breast, and is able to uniformly distribute heat in the heating zone after power is applied.

[0006] Furthermore, the conductive heating coating is a conductive ink or a conductive paste.

[0007] Furthermore, the conductive heating coating is provided with a heating material and a bonding material. The heating material includes at least one of a metal material, a conductive polymer material, a carbon-based material, a carbon fiber, or graphene. The bonding material includes at least one of an epoxy resin, a polyurethane, or an acrylate.

[0008] Furthermore, the bonding portion includes a first cover and a second cover connected to the first cover, and the conductive heating coating is disposed between the first cover and the second cover.

[0009] Furthermore, the bra is made of a soft material, and the hardness of the first bra body is greater than that of the second bra body.

[0010] Furthermore, the conductive heating coating includes a heating circuit, which is covered on the bonding portion by one of the following methods: printing, coating, inkjet printing, or vacuum coating.

[0011] Furthermore, the heating circuit includes multiple heating circuits arranged around the bonding portion, and the multiple heating circuits are connected in parallel with each other.

[0012] Furthermore, the fitting part is provided with a mounting part on the side away from the breast, and the heating assembly also includes a connecting terminal that is connected to the conductive heating coating and electrically connected to an external circuit. The connecting terminal is located in the mounting part and protrudes from the mounting part.

[0013] Furthermore, the heating assembly also includes a magnetic suction member disposed on the mounting portion, the magnetic suction member being used for magnetic connection with an external host.

[0014] Furthermore, the conductive heating coating is provided with a first connecting portion and a second connecting portion that are both connected to the connecting terminal, and the heating assembly also includes a temperature sensor disposed on the bonding portion and connected to the connecting terminal, the temperature sensor being disposed between the first connecting portion and the second connecting portion.

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

[0016] This invention uses a conductive heating coating as a heating element, and places the conductive heating coating on the side of the contact area away from the breast to form a heating zone. The conductive heating coating achieves uniform heating of the heating zone. Compared with traditional resistance wire, the conductive heating coating can cover a larger area, and its thickness and resistivity are more consistent, which can make the temperature distribution of the heating zone more uniform and reduce the risk of burns caused by local overheating, effectively improving the safety of use and the comfort of the user.

[0026] Example 1

[0027] like Figures 1 to 6 The heating bra structure of the breast pump includes a bra 1 and a heating component 2 connected to the bra. The bra 1 includes a fitting part 11 that fits against the breast area. The heating component 2 includes a conductive heating coating 21 disposed on the fitting part 11. The conductive heating coating 21 forms a heating area by covering the side of the fitting part 11 away from the breast, and can uniformly distribute the heating area when energized.

[0028] This invention uses a conductive heating coating as a heating element, and places the conductive heating coating on the side of the contact area away from the breast to form a heating zone. The conductive heating coating achieves uniform heating of the heating zone. Compared with traditional resistance wire, the conductive heating coating can cover a larger area, and its thickness and resistivity are more consistent, which can make the temperature distribution of the heating zone more uniform and reduce the risk of burns caused by local overheating, effectively improving the safety of use and the comfort of the user.

[0029] Specifically, this invention provides a conductive heating coating on the contact part that fits the breast. When the breast pump is started, the heating component receives an external control signal, and the conductive heating coating starts to work, generating heat. The heat is transferred to the breast through the contact part, keeping the breast warm and reducing discomfort and breast contraction caused by low temperature stimulation. The external control system can monitor and adjust the heating temperature to ensure that the temperature is kept within a suitable range to provide the best breast pumping experience.

[0030] like Figures 2 to 6 The diagram shows a heated breast shield structure for a breast pump, wherein the conductive heating coating 21 is a conductive ink or conductive paste.

[0031] This invention uses conductive ink or conductive paste as a conductive heating coating, which ensures that the heated breast shield heats up evenly after being powered on, avoiding local overheating or undercooling. Because conductive ink and conductive paste have good conductivity, the heating temperature and area can be precisely controlled by precisely controlling the coating thickness and pattern of the conductive ink or conductive paste, meeting the needs of different users. At the same time, because conductive ink or conductive paste can form a thin coating, the heated breast shield can maintain good softness and comfort while maintaining heating performance.

[0032] Furthermore, the conductive heating coating is provided with a heating material and a bonding material. The heating material includes at least one of a metal material, a conductive polymer material, a carbon-based material, a carbon fiber, or graphene. The bonding material includes at least one of an epoxy resin, a polyurethane, or an acrylate.

[0033] In this invention, the conductive heating coating is provided with a heating material. When electricity is applied, the heating material generates heat, which is evenly transferred to the contact area through the coating, thereby heating the breast. Compared with breast pumps that use traditional resistance wire heating, the conductive heating coating can more effectively cover the contact area and heat it. Furthermore, the conductive heating coating has better flexibility and uniform heating performance. When it is placed on the contact area, it will not affect the flexibility of the contact area, allowing the contact area to better conform to the shape of the breast and provide a more comfortable and effective heating effect.

[0034] Because carbon-based materials, carbon fibers, and graphene all possess excellent electrical and thermal conductivity, they are not only lightweight but also provide uniform heating. Therefore, using carbon-based materials, carbon fibers, or graphene as heating materials allows the conductive heating coating to exhibit rapid response and efficient heating. Similarly, metals, due to their excellent electrical conductivity, can also be used as heating materials. Metal materials can rapidly heat up after being energized, and the heating efficiency and temperature range can be controlled by adjusting the type and proportion of metals. In this invention, the metal is made into fine powder or fiber form and added to the heating material to ensure the flexibility of the conductive heating coating. In addition, the heating material can also be made of metal oxides, some of which have good electrothermal conversion capabilities. For example, materials such as tin oxide and indium oxide can not only improve the stability and durability of the coating, but also regulate the heating efficiency and temperature distribution to a certain extent. In addition, conductive polymer materials are also polymer compounds with excellent conductivity. They can form a conductive network in the ink to realize the transfer of electrical energy and the generation of heat. Therefore, by using conductive ink as a conductive heating coating and combining it with at least one of the following heating materials: metal materials, conductive polymer materials, carbon-based materials, carbon fibers, or graphene, the conductive ink can be evenly distributed on the bonding part to form a uniform heating area. After being energized, the temperature of the entire heating area can remain consistent, achieving a uniform, efficient, and safe heating effect on the breast area, providing a comfortable and consistent warm environment for the breast.

[0035] Optionally, in some embodiments, the heating materials of different types mentioned above can be used in combination and the heating performance can be customized according to actual needs so that the heated bra can meet the needs of different application scenarios. By using these efficient heating materials, not only can the preheating time be shortened, but also the uniform temperature distribution can be guaranteed, providing users with a more comfortable experience. At the same time, through reasonable material ratio and design, the safety and stability of the heating process can be ensured, the risk of overheating can be avoided, and the safety of the heated bra structure can be further enhanced.

[0036] Furthermore, the conductive heating coating is provided with an adhesive material, which includes at least one of epoxy resin, polyurethane, and acrylate. By using the adhesive material as a carrier for the heating material, it is possible to ensure that the heating material and the adhesive material are effectively adhered to the bonding part after mixing. At the same time, it can ensure the flexibility and durability of the conductive heating coating, prevent it from falling off from the bonding part, and effectively improve the connection stability and reliability between the conductive heating coating and the bonding part. In addition, the adhesive material can also ensure the uniform distribution of the heating material in the conductive heating coating, help to evenly disperse the heating material, prevent particle agglomeration, and thus ensure the consistency of the conductivity of the conductive heating coating.

[0037] Taking epoxy resin as an example, epoxy resin can provide good tensile and tear resistance. Epoxy resin-based conductive heating coatings are more durable. At the same time, epoxy resin has excellent adhesion to a variety of substrates, which means that it can form a stable coating on different surfaces, making it suitable for diverse application scenarios. Therefore, epoxy resin can effectively fix the heating material to the substrate, reducing delamination or peeling caused by time or environmental changes, and improving the connection stability and reliability between the conductive heating coating and the bonding part.

[0038] Taking polyurethane as an example, polyurethane has excellent flexibility and ductility, which means that it can adapt to substrates of various shapes and curvatures while maintaining good conductivity. Due to its good elasticity and recovery ability, polyurethane-based conductive heating coatings can maintain structural integrity and functional stability under repeated bending, stretching and other conditions.

[0039] Taking acrylates as an example, acrylate polymers can provide good flexibility and a certain degree of elasticity, so that the heating layer formed by the conductive heating coating can remain intact under bending or stretching. This makes it suitable for flexible electronic devices or other applications that need to adapt to deformation. At the same time, acrylate-based inks usually have good rheological properties and are easy to apply through various technologies such as screen printing and inkjet printing, thereby achieving complex patterns and high-precision coating applications. Therefore, by using acrylate-based conductive inks, not only can the safety and effectiveness of heating components be ensured, but users can also be provided with a more comfortable and reliable experience.

[0040] Example 2

[0041] Example 2, based on Example 1, also has the following implementation method:

[0042] like Figures 2 to 6 The diagram shows a heated breast shield structure for a breast pump. The fitting part 11 includes a first shield 111 and a second shield 112 connected to the first shield 111. The conductive heating coating 21 is disposed between the first shield 111 and the second shield 112.

[0043] This invention designs the fitting part as a first cover and a second cover, and places the conductive heating coating between the first cover and the second cover. This allows the conductive heating coating to be wrapped by the first cover and the second cover, reducing the risk of direct contact with the skin, avoiding potential burn hazards, and effectively improving the safety of the heated bra. At the same time, it allows heat to be transferred more evenly to the breast area, improving the heating effect and enhancing comfort. In addition, placing the conductive heating coating between the first cover and the second cover prevents the heating layer from being exposed, which is beneficial for maintaining cleanliness and extending service life, effectively improving the convenience of maintenance and the service life of the heated bra.

[0044] Furthermore, the bra 1 is made of soft material, and the hardness of the first cover 111 is greater than that of the second cover 112.

[0045] This invention uses soft materials as the material for the bra, allowing it to better adapt to different breast shapes and provide a more fitting and comfortable wearing experience. The soft material also helps reduce pressure during wear, avoiding unnecessary compression of the breasts and thus improving user comfort. Furthermore, in this invention, the second part of the bra is the section that directly contacts the breast, while the first part primarily provides support. By designing the first part to be more rigid than the second part, the comfort of wearing the bra can be further improved while ensuring support, reducing potential discomfort from prolonged use.

[0046] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the Shore hardness of the first cover 111 is 40-60°, and the Shore hardness of the second cover 112 is 20-40°. By setting the Shore hardness of the first cover to 40-60°, the first cover within this hardness range can maintain a certain shape stability while having sufficient softness to ensure good contact with the breast, improving milk pumping efficiency and comfort. Setting the Shore hardness of the second cover to 20-40° and making it softer than the first cover increases wearing comfort, reduces friction and pressure on the skin around the breast, and also facilitates heat conduction of the conductive heating coating, resulting in a more uniform temperature distribution and effectively improving the comfort of using the heated bra.

[0047] Specifically, in some embodiments, the elastic material can be silicone, TPU thermoplastic polyurethane, TPE thermoplastic elastomer, etc. These materials all have the characteristics of elasticity and flexibility, which can fully meet the usage requirements of bras.

[0048] Preferably, in some embodiments, the bra is made of silicone.

[0049] Preferably, in some embodiments, the Shore hardness of the first cover is 50°, and the Shore hardness of the second cover is 30°.

[0050] Example 3

[0051] Example 3, based on Example 2, also has the following implementation method:

[0052] like Figures 2 to 6 The diagram shows a heated breast shield structure for a breast pump. The conductive heating coating 21 includes a heating circuit 211, which is covered on the bonding portion 11 by one of the following methods: printing, coating, inkjet printing, or vacuum coating.

[0053] In this invention, the heating circuit can be printed onto the bonding part. This method is suitable for mass production and allows for precise control of the circuit pattern and thickness, ensuring the uniformity of the conductive heating coating. Coating is another method for covering the heating circuit onto the bonding part. Through coating, a thin and uniform conductive heating coating can be formed, improving heating efficiency and comfort. In addition, inkjet printing technology can also be used to precisely print the heating circuit onto the bonding part. This method has high flexibility and customizability, allowing adjustment of the circuit pattern and density according to different needs. Furthermore, the heating circuit can also be covered onto the bonding part through vacuum coating. Vacuum coating is a high-precision covering method that can form an extremely thin and uniform conductive heating coating on the bonding part. This method is suitable for applications with extremely high requirements for coating thickness and uniformity. Therefore, using vacuum coating to cover the heating circuit onto the bonding part can effectively control the thickness and uniformity of the conductive heating coating. Thus, all of the above covering methods can ensure that the heating circuit forms a uniform and continuous coating on the bonding part, thereby achieving uniform heating throughout the heating area.

[0054] Furthermore, the conductive heating coating 21 includes multiple heating circuits 211, which are arranged around the bonding portion 11, and the multiple heating circuits 211 are connected in parallel with each other.

[0055] This invention divides the conductive heating coating into multiple independent heating circuits, enabling more precise temperature control and a more uniform heat distribution. The heating circuits are arranged around the contact area, i.e., the area in contact with the breast, ensuring that heat is evenly transferred to the breast from multiple directions, avoiding localized overheating or cold spots and providing a more comfortable experience. Furthermore, the multiple heating circuits are connected in parallel, meaning that even if one circuit fails, the others can still function normally. The parallel circuit design also effectively balances the current distribution in each part, preventing localized overload of the heating circuits and significantly improving the safety of the heated bra.

[0056] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the cross-sectional shape of the heating circuit 211 can be one of a serpentine, annular, wavy, Z-shaped, or arc-shaped form. The heating circuit can be arranged in a circuitous manner, for example, by using a continuous serpentine, continuous annular, continuous wavy, continuous Z-shaped, or continuous arc-shaped arrangement. Such a design can increase the contact range between the heating circuit and the bonding part, so that the heat can be transferred to the bonding part more evenly and comprehensively. Moreover, since the heating circuit is distributed in a circuitous manner, it extends the heat transfer path within a limited space, further improving the heating efficiency of the heating circuit on the bonding part, thereby providing a more comfortable user experience.

[0057] Example 4

[0058] Example 4, based on the above examples, also has the following implementation method:

[0059] like Figures 2 to 6 The heating bra structure of a breast pump shown has a mounting part 113 on the side of the fitting part 11 away from the breast. The heating component 2 also includes a connection terminal 22 that is connected to the conductive heating coating 21 and electrically connected to an external circuit. The connection terminal 22 is located in the mounting part 113 and protrudes from the mounting part 113.

[0060] This invention provides an installation part on the side of the fitting part away from the breast, and places a connecting terminal that is connected to the conductive heating coating and electrically connected to an external circuit in the installation part to fix the connecting terminal. The connecting terminal is a component used to electrically connect the conductive heating coating to an external power supply or other control circuit. The connecting terminal protrudes from the installation part, making the electrical connection between the connecting terminal and the external power supply or other control circuit more convenient and reliable, effectively improving the stability and reliability of the heated bra.

[0061] like Figure 4 The heating breast shield structure of the breast pump shown is provided. The heating component 2 also includes a magnetic suction member 24 disposed on the mounting part 113. The magnetic suction member 24 is used for magnetic connection with the external host.

[0062] This invention features a magnetic attachment in the mounting section that connects to an external host unit, allowing the heated breast cover to be easily connected or disconnected. Through magnetic force, the user simply brings the heated breast cover close to the host unit's interface for automatic alignment and secure connection, eliminating the need for complex plugging and unplugging operations. This magnetic connection method greatly simplifies the connection process between the heated breast cover and the external host unit. Especially for components like breast covers that require frequent disassembly and cleaning, compared to traditional plug-and-play connections, the magnetic design reduces the precision requirements for alignment, lowers the possibility of misoperation, and effectively improves the user experience. Simultaneously, the magnetic attachment provides sufficient attraction force to ensure a stable and reliable connection, preventing easy disconnection even with slight pulling or movement, thus guaranteeing the stability and reliability of the connection between the heated breast cover and the external host unit.

[0063] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the magnetic component is disposed on the inner side of the mounting part, so that the mounting part completely covers the magnetic component and prevents it from being exposed. This design can protect it from the influence of the external environment to a certain extent, such as preventing it from directly colliding with external hard objects, thereby extending its service life. Moreover, placing the magnetic component on the inner side of the mounting part helps to maintain the simple and beautiful overall appearance of the bra, effectively improving the aesthetics of the bra.

[0064] like Figures 2 to 5 The heating breast shield structure of the breast pump shown is provided with a first connecting part 212 and a second connecting part 213 that are both connected to the connecting terminal 22. The heating component 2 also includes a temperature sensor 23 disposed on the fitting part 11 and connected to the connecting terminal 22. The temperature sensor 23 is disposed between the first connecting part 212 and the second connecting part 213.

[0065] The first and second connecting parts of this invention are respectively connected to the connecting terminals to form a complete circuit loop. This design ensures that the current can flow evenly through the entire conductive heating coating, thereby achieving uniform heating. Furthermore, this invention also includes a temperature sensor connected to the connecting terminals for measuring the temperature of the contact area. The temperature sensor is positioned between the first and second connecting parts, meaning it is at the core of the heating zone, allowing for the most accurate temperature readings and ensuring precise temperature control. Specifically, during the operation of the heated bra, the temperature sensor transmits the monitored temperature to the external control system via the connecting terminals. The external control system adjusts the current supplied to the conductive heating coating according to a preset program, thereby controlling the temperature of the heated bra and ensuring it remains within a suitable range, thus improving the comfort and safety of the heated bra.

[0066] 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.
