Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products, specifically a breast pump with a heating function. Background Technology

[0002] As a key device to assist breastfeeding, breast pumps are widely used in the daily lactation care of breastfeeding women. Their core function is to achieve efficient milk collection by simulating the rhythm and strength of a baby's natural sucking. This not only meets the lactation needs of breastfeeding women who are unable to breastfeed due to objective factors such as work or going out, but also helps relieve breast discomfort in cases of milk stasis or breast engorgement, thereby helping to maintain the breastfeeding cycle.

[0003] To improve user comfort, existing breast pumps typically include heating elements that transfer heat to the breasts through the vent, thus relieving breast engorgement. However, the heating elements are often directly mounted on the vent. As the part of the breast pump that comes into direct contact with the breast, the vent can easily retain milk in its internal milk channels after each pumping session, requiring frequent cleaning. During cleaning, moisture inevitably comes into contact with the heating elements mounted on the vent, making them susceptible to moisture damage or short circuits, thus affecting their lifespan.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] To address the above problems, this utility model proposes a breast pump with a heating function, and the technical solution adopted is as follows: A breast pump with a heating function includes a main unit, a milk bowl, and a horn cover connected to the main unit, and also includes a heating component electrically connected to the main unit. The main unit includes a main unit housing, the horn cover includes a milk suction channel communicating with the milk bowl and a contact portion for contacting the breast, the main unit housing includes a connecting end face connected to the contact portion, and the heating component is disposed inside the main unit housing and adjacent to the connecting end face.

[0006] Furthermore, the connecting end face and the contact portion together form a contact surface that contacts the breast, and the heating component is used to heat the contact surface.

[0007] Furthermore, the cross-section of the contact portion is smaller than the cross-section of the connecting end face, and the contact portion and the connecting end face are together attached to the breast surface. The heating component conducts heat to the breast tissue through the connecting end face and the contact portion.

[0008] Furthermore, the cross-section of the contact portion is greater than or equal to the cross-section of the connecting end face, the contact portion is independently attached to the breast surface, and the heating component transfers heat to the contact portion through the connecting end face, so that the contact portion conducts heat to the breast tissue.

[0009] Furthermore, the heating component is fixed inside the main unit housing by overmolding, so that the heating component and the main unit housing form an integral structure.

[0010] Furthermore, the heating component is fixedly installed inside the main unit housing.

[0011] Furthermore, the heating assembly includes a heating element for generating heat, a base covering the outside of the heating element and attached to the main unit housing, and a connection terminal, wherein the heating element is electrically connected to the main unit through the connection terminal.

[0012] Furthermore, the substrate is made of a composite of silicone material and hard plastic material. The hard plastic material is located on the side close to the inner wall of the host and serves as a structural support layer. The silicone material is located between the heating element and the hard plastic material and serves as a thermally conductive buffer layer.

[0013] Furthermore, the heating element is a heating film.

[0014] Furthermore, the heating element is a semiconductor element.

[0015] The beneficial effects of this utility model are as follows: This invention places the heating component inside the main housing and near the connection end face, so that the heating component transfers heat to the connection end face only through thermal conduction. This completely avoids the heating component coming into contact with water during the cleaning of the speaker cover, which helps to significantly reduce the risk of short circuits, corrosion or insulation failure caused by moisture, and effectively improves the service life and safety of the heating component.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] Example 1: like Figures 1 to 9 The illustrated breast pump with heating function includes a main unit 1, a milk bowl 2, and a speaker cover 3 connected to the main unit 1. It also includes a heating component 4 electrically connected to the main unit 1. The main unit 1 includes a main unit housing 10. The speaker cover 3 includes a milk suction channel 31 communicating with the milk bowl 2 and a contact portion 32 for contacting the breast. The main unit housing 10 includes a connecting end face 11 connected to the contact portion 32. The heating component 4 is disposed inside the main unit housing 10 and adjacent to the connecting end face 11.

[0022] This invention places the heating component inside the main housing and near the connection end face, so that the heating component transfers heat to the connection end face only through thermal conduction. This completely avoids the heating component coming into contact with water during the cleaning of the speaker cover, which helps to significantly reduce the risk of short circuits, corrosion or insulation failure caused by moisture, and effectively improves the service life and safety of the heating component.

[0023] Furthermore, by placing the heating component 4 on the outside of the main housing 10 and connecting it to the speaker cover 3, the speaker cover 3 can be removed separately during cleaning. However, this structure exposes the heating component 4 to the external environment, and the electrical interface of the heating component 4 is easily affected by external factors such as moisture, milk, or dust, which can easily damage the electrical interface of the heating component 4. In contrast, this invention completely avoids exposing the heating component 4 by embedding the heating component 4 entirely within the main housing 10, ensuring that the heating component 4 is always in a sealed, dry, and stable environment, thereby improving safety and durability.

[0024] Furthermore, by setting up a milk suction channel 31 that communicates with the milk bowl 2, the expressed milk can flow into the milk bowl 2 through the milk suction channel 31, which helps to ensure the collection and storage of milk and improves the convenience of using the breast pump.

[0025] Furthermore, such as Figures 1 to 9 The connecting end face 11 shown and the contact portion 32 together form a contact surface 5 that contacts the breast, and the heating component 4 is used to heat the contact surface 5.

[0026] Furthermore, by cooperating with the connecting end face 11 of the main unit 1 and the contact part 32 of the speaker cover 3 to form a continuous contact surface 5, the heat energy of the heating component 4 can be evenly conducted to the area in contact with the breast, avoiding local overheating or heating blind spots caused by the fixed size of the traditional single contact part 32, which is conducive to improving the comfort of use and effectively relieving milk stasis and swelling.

[0027] Furthermore, the heating component 4 only needs to act on the inner wall of the main housing 10 to indirectly heat the contact surface 5, eliminating the need to integrate the heating element 41 inside the easily contaminated speaker cover 3. This fundamentally isolates the heat source from the residual milk environment, significantly reducing the risk of short circuits, insulation failures, and metal corrosion caused by water ingress during cleaning, thus helping to extend the service life of the equipment and improve its safety.

[0028] Preferably, the connecting end face 11 and the contact portion 32 are coaxially arranged. When the cross-section of the contact portion 32 is smaller than the cross-section of the connecting end face 11, the contact portion 32 and the connecting end face 11 are in contact with the breast together. When the cross-section of the contact portion 32 is greater than or equal to the connecting end face 11, the contact portion 32 is in contact with the breast alone. The main unit 1 is provided with a heating adjustment controller for controlling the working state of the heating component 4. Users can adjust the heating temperature of the heating component 4 according to actual usage needs through the heating adjustment controller, which is beneficial to improving the practicality of the breast pump. At the same time, combined with the heat transfer under different contact modes, users can accurately control the temperature of the contact surface, avoiding overheating discomfort or insufficient heating problems that may be caused by a fixed temperature, which is beneficial to improving the personalized user experience.

[0029] Furthermore, such as Figure 6 The cross-section of the contact portion 32 shown is smaller than the cross-section of the connecting end face 11. The contact portion 32 and the connecting end face 11 are together attached to the surface of the breast. The heating component 4 conducts heat to the breast tissue through the connecting end face 11 and the contact portion 32.

[0030] Specifically, the contact portion 32 and the connecting end face 11 are coaxially arranged, and the cross-section of the contact portion 32 is smaller than the cross-section of the connecting end face 11. In this case, the contact portion 32 cannot fully fit the surface of the breast, and the connecting end face 11 needs to cooperate with the contact portion 32 so that it can fully fit the surface of the breast.

[0031] Furthermore, when the contact portion 32 and the connecting end face 11 are together in contact with the breast, the connecting end face 11 can help the contact portion 32 form a more complete fit structure, making up for the fit gap problem that may be caused by the small cross-section of the contact portion 32. The contact portion 32 and the connecting end face 11 work together to better fit the breast contour, which is conducive to improving the tightness of the fit with the breast surface.

[0032] Furthermore, when the cross-section of the contact portion 32 is smaller than the cross-section of the connecting end face 11, the connecting end face 11 of the main unit 1 can directly participate in contact with the breast, so that the effective heating area is no longer limited to the size of the speaker cover 3 itself, but extends to a larger area of ​​the end face of the main unit 1. The larger contact area can distribute and transfer heat to the breast tissue more quickly and evenly, avoiding the problem of local overheating or uneven temperature that may be caused by small area heating, thereby significantly improving the comfort of hot compress and the efficiency of relieving swelling and pain.

[0033] Furthermore, such as Figures 1 to 9 The heating component 4 shown is fixed inside the main housing 10 by overmolding, so that the heating component 4 and the main housing 10 form an integral structure.

[0034] Furthermore, the heating component 4 is fixed inside the main housing 10 by overmolding and forms an integrated structure, which can completely eliminate the risk of gaps or loosening that may exist in traditional assembly connections. Compared with detachable or simple splicing installation methods, overmolding allows the heating component 4 to be tightly integrated with the main housing 10. During the use, transportation or daily vibration of the breast pump, the heating component 4 will not shift or fall off, ensuring that the heating component 4 is always in the preset position adjacent to the connection end face 11, thus ensuring the stability of heat transfer.

[0035] Furthermore, the overmolding process enables a large-area and seamless close contact between the heating component 4 and the main housing 10, which helps to reduce the thermal resistance of the heat conduction interface. Heat can be transferred more efficiently from the heating source heating component 4 to the connection end face 11 of the main housing 1, reducing the loss of heat energy during the internal transfer process.

[0036] Specifically, the heating component 4 is first manufactured, and then the manufactured heating component 4 is placed in the mold of the main unit housing 10. Next, molten thermoplastic elastomer or medical-grade silicone material is injected. After high temperature and high pressure molding, these materials will completely wrap around and penetrate the outer surface of the heating component 4. After cooling and solidification, they will fuse with the main unit housing 10 to form an integrated structure.

[0037] Furthermore, such as Figures 1 to 9 The heating assembly 4 shown includes a heating element 41 for generating heat, a base 42 covering the outside of the heating element 41 and attached to the main unit housing 10, and a connection terminal 43. The heating element 41 is electrically connected to the main unit 1 through the connection terminal 43.

[0038] Furthermore, by integrating the heating element 41, the base 42, and the connection terminal 43 into a modular component, it is beneficial to achieve a high degree of integration of the heating function, avoiding the problems of complex assembly, poor contact, or disordered heat flow path caused by traditional scattered wiring. As a carrier, the base 42 can not only stably fix the heating element 41, but also ensure that it fits tightly with the main housing 10, which helps to improve heat conduction efficiency and device stability, and effectively enhances the overall reliability of the breast pump.

[0039] Furthermore, the connection terminal 43 serves as a dedicated electrical interface, which facilitates a standardized and reliable connection between the heating element 41 and the power supply of the host 1, avoiding the risks of loosening and short circuits that may result from direct soldering or arbitrary connection of wires; the substrate 42 completely encloses the heating element 41, completely isolating it from the external environment, greatly extending the service life of the heating assembly 4, while ensuring electrical safety during long-term use.

[0040] Furthermore, such as Figures 1 to 9The substrate 42 shown is made of a composite of silicone material and hard plastic material. The hard plastic material is located on the side close to the inner wall of the host 1 and serves as a structural support layer. The silicone material is located between the heating element 41 and the hard plastic material and serves as a thermally conductive buffer layer.

[0041] Furthermore, the hard plastic material near the main housing 10 in the substrate 42 serves as a structural support layer, possessing high hardness and morphological stability. This provides a solid structural support for the entire heating component 4, ensuring that the heating component 4 is not easily deformed or displaced after being installed in the main housing 10. It maintains a tight fit with the inner wall of the main housing 10, preventing the heating component 4 from loosening due to insufficient support from the substrate, which could affect heat transfer or safety of use.

[0042] Furthermore, the silicone material located between the heating element 41 and the hard plastic material serves as a thermally conductive buffer layer. The silicone material has good thermal conductivity, which can quickly conduct the heat generated by the heating element 41 to the hard plastic support layer and then to the main housing 10, preventing heat from accumulating on the surface of the heating element 41. At the same time, the flexible nature of the silicone can fill the tiny gaps between the heating element 41 and the hard plastic material, reducing heat loss during the heat transfer process and improving the uniformity of heat conduction.

[0043] Furthermore, the silicone material has excellent insulation properties. As a buffer layer between the heating element 41 and the hard plastic layer, it can further isolate the risk of electrical connection between the heating element 41 and the inner wall of the main body housing 10, and avoid short circuits due to insufficient insulation of the material. At the same time, the flexible properties of silicone can better adapt to the shape of the heating element 41, tightly wrap the heating element, reduce the gap between the heating element 41 and the substrate 42, and help reduce the possibility of external dust and moisture intrusion.

[0044] Furthermore, such as Figures 1 to 9 The heating element 41 shown is a heating film.

[0045] Furthermore, the heating film has planar heating characteristics. Compared with traditional point or line heating elements 41, the heating film can form a more comprehensive and uniform heat coverage area. When the heating film is used as the heating element 41, it can fully adhere to the silicone thermally conductive buffer layer in the substrate 42, and evenly transfer heat to the silicone layer. Then, the heat is dispersed through the silicone layer to the hard plastic support layer and the inner wall of the main unit housing 10, ultimately making the heat distribution on the contact surface 5 more even, avoiding local overheating or heating dead zones, effectively relieving breast swelling and pain, and preventing discomfort to the breast caused by local high temperature, which is conducive to improving user comfort.

[0046] Furthermore, the heating film is thin and flexible, and does not require additional complex installation structure. It perfectly fits the composite configuration of the substrate 42. The flexible nature of the heating film can be slightly adjusted according to the shape of the substrate to ensure close contact with the silicone layer and reduce heat transfer gaps. At the same time, the structural configuration of the heating film does not increase the overall thickness of the heating component 4, which helps to save installation space on the inner side wall of the main unit housing 10.

[0047] Furthermore, the heating film has a stable heating power and over-temperature protection characteristics, which can avoid the risk of overheating caused by power fluctuations.

[0048] The implementation method of Example 2 is as follows: The difference between Example 2 and Example 1 is as follows: Figure 7 The cross-section of the contact portion 32 shown is greater than or equal to the cross-section of the connecting end face 11. The contact portion 32 is independently attached to the surface of the breast. The heating component 4 transfers heat to the contact portion 32 through the connecting end face 11, so that the contact portion 32 conducts heat to the breast tissue.

[0049] Specifically, the contact portion 32 and the connecting end face 11 are coaxially arranged, and the cross-section of the contact portion 32 is greater than or equal to the cross-section of the connecting end face 11. At this time, the contact portion 32 can completely fit the surface of the breast, and the connecting end face 11 will not directly contact the breast. The heating component 4 conducts heat to the contact portion 32 through the connecting end face 11, and then the contact portion 32 applies heat to the breast tissue.

[0050] Furthermore, when the cross-section of the contact portion 32 is greater than or equal to the cross-section of the connecting end face 11, the contact portion 32 can independently conform to the surface of the breast, which can more fully cover the breast contact area and adapt to the use needs of breasts with larger contours or special shapes. Compared with the contact portion 32 and the connecting end face 11 conforming together, the independently conforming contact portion 32 can reduce the additional contact between the connecting end face 11 and the breast, avoid the pressure caused by the conforming of multiple parts, further improve the conforming comfort during the breast pumping process, and reduce the risk of local pressure pain.

[0051] Furthermore, the heating component 4 transfers heat to the contact portion 32 through the connecting end face 11, and then the contact portion 32 conducts the heat to the breast tissue, forming an indirect heat conduction path of "heating component 4 - connecting end face 11 - contact portion 32". This helps to avoid direct connection between the heating component 4 and the contact portion 32. Even if the contact portion 32 needs to be cleaned frequently, moisture is unlikely to penetrate into the heating component 4 through the contact portion 32, effectively preventing the heating component 4 from getting damp and short-circuiting.

[0052] The implementation method of Example 3 is as follows: The difference between Example 3 and Example 1 is as follows: Figures 1 to 9The heating component 4 shown is fixedly installed inside the main unit housing 10; Specifically, the heating component 4 is fixedly installed inside the main unit housing 10 so that the user cannot or cannot easily disassemble the heating component 4, which can avoid safety hazards such as electric shock and component damage caused by misoperation, and at the same time prevent the heating component 4 from becoming loose during use.

[0053] Optionally, in some embodiments, the heating component 4 is installed inside the main housing 10 by means of a threaded connection. A mounting post with internal threads is preset on the inner side wall of the main housing 10, and a through hole is provided at the corresponding position of the heating component 4. The screw is passed through the through hole and tightened to the mounting post. The threaded connection has high strength and is suitable for application scenarios that require long-term stable fixation.

[0054] Optionally, in some embodiments, the heating component 4 is installed inside the main housing 10 by means of a snap-fit ​​connection. The inner side of the main housing 10 is provided with an elastic snap-fit, and the edge of the heating component 4 is provided with a corresponding slot. During assembly, the snap-fit ​​deforms elastically and then snaps into the slot to fix the heating component 4. The snap-fit ​​connection does not require additional tools, which is beneficial to improving production assembly efficiency and helps to ensure a tight fit between the heating component 4 and the main housing 10.

[0055] Optionally, in some embodiments, the heating component 4 is installed inside the main housing 10 via a slot connection. The main housing 10 is provided with a slot with a positioning protrusion. The heating component 4 is designed as a plate-like structure that fits the slot. When inserted, it is fixed by the protrusion engaging with the groove on the edge of the heating component 4. The slot connection helps to ensure that the position of the heating component 4 is relatively stable inside the main housing 10, which helps to ensure the heat conduction efficiency.

[0056] Optionally, in some embodiments, the heating component 4 is installed inside the main housing 10 by magnetic attraction. A neodymium iron boron magnet is embedded in the main housing 10, and an iron-containing metal sheet is set at the corresponding position of the heating component 4. The initial fixation is achieved by magnetic attraction, and the positioning post is used to prevent displacement. The magnetic attraction setting is conducive to quick alignment and installation during production, while avoiding excessive tightening that may affect the heating component 4.

[0057] The implementation method of Example 4 is as follows: The difference between Example 4 and Example 1 is as follows: Figures 1 to 9 The heating element 41 shown is a semiconductor element.

[0058] Furthermore, semiconductor heating elements typically have extremely high electrothermal conversion efficiency and extremely fast thermal response speed, and can quickly reach the predetermined temperature after being powered on, which helps to reduce the user's waiting time.

[0059] Optionally, in some embodiments, the semiconductor element is a PTC ceramic heating element. The PTC ceramic heating element has a positive temperature coefficient characteristic. When the temperature rises to a certain value, the resistance will increase sharply, thereby automatically limiting the temperature rise and achieving overheat protection without complex circuits. Secondly, the PTC ceramic heating element heats evenly and has strong stability, and can gently transfer heat to the main unit housing 10 through the base silicone layer.

[0060] Optionally, in some embodiments, the semiconductor element is a silicon carbide semiconductor heater. Using silicon carbide semiconductor material as the heating element has the characteristics of high temperature resistance, chemical stability and strong oxidation resistance. It can maintain stable performance even at high temperatures, which is beneficial to improving the stability of the breast pump's operation.

[0061] Optionally, in some embodiments, the semiconductor element is a silicon-based semiconductor heating element. The semiconductor heating element made of silicon as a substrate has excellent electro-thermal conversion efficiency and precise temperature controllability. The heating temperature can be precisely adjusted by the magnitude of the current. Secondly, its thin and light structure can fit into the installation space within the main unit housing 10, and the heating response speed is fast, which can quickly reach the preset temperature, thus helping to meet the user's need for immediate relief of breast pain.

[0062] 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.
