Description

Technical Field

[0001] This utility model relates to the field of breast pumps, specifically a breast pump component with hot and cold compress functions. Background Technology

[0002] With the continuous development of breast pump technology, its functions have become increasingly diversified to meet different user needs. Recent studies have found that hot and cold compresses are very important for breastfeeding women. Hot compresses can unclog milk ducts, making milk expression smoother; while cold compresses can relieve pain and reduce swelling during engorgement. Therefore, many breast pumps have been equipped with hot or cold compress functions to improve user comfort and meet these needs.

[0003] Nevertheless, while current breast pumps on the market do meet users' needs for hot or cold compresses to some extent, they can only provide one of these functions. This means that in actual use, if users need to switch between hot and cold compresses, they must stop their current operation and change to a different device or accessory. This not only increases the complexity and time cost of use but also reduces the consistency and comfort of the overall experience.

[0004] Therefore, it is necessary to develop a breast pump component with both hot and cold compress functions, so that users can easily and quickly switch between the two functions. Utility Model Content

[0038] Example 1:

[0039] Please see Figure 1-13 This utility model proposes a breast pump assembly with hot and cold compress functions, including a breast pump assembly body 1, wherein the breast pump assembly body 1 includes a breast pump assembly 2, a heat exchange assembly 3 for providing a heat or cold medium to the breast pump assembly 2, and a connecting pipe 4 for conveying the heat or cold medium. The breast pump assembly 2 is provided with a fitting part 21 that fits against the breast. The heat exchange assembly 3 and the fitting part 21 are circulated and supplied with a cold or hot medium through the connecting pipe 4 so that the surface of the fitting part 21 produces a cold or hot compress effect.

[0040] This invention, by setting up a heat exchange component 3 and a connecting pipe 4 connecting the heat exchange component 3 and the fitting part 21, allows users to adjust the temperature of the medium in the heat exchange component 3 according to their needs. The medium can be transported back and forth between the fitting part 21 and the heat exchange component 3 through the connecting pipe 4, so that the temperature of the medium can be transferred to the surface of the fitting part 21 that is in contact with the breast. This realizes the hot and cold compress functions of the breast pumping component 2, allowing users to quickly and conveniently switch between hot and cold compress modes according to their own needs without interrupting operation or changing equipment, thereby improving the user's convenience and comfort.

[0041] Specifically, when the user needs a hot compress, the heat exchange component 3 heats the medium to a suitable temperature and delivers it to the fitting part 21 through the connecting pipe 4. The connecting pipe 4 also enables continuous circulation of the medium between the fitting part 21 and the heat exchange component 3. In this embodiment, the medium is delivered into the fitting part 21, allowing the temperature of the medium to be transferred to the fitting part 21 more efficiently, and then to the breast. This design maintains a stable warm state on the surface of the fitting part 21, which is very beneficial for promoting milk secretion. Similarly, when the user needs a cold compress, the heat exchange component 3 cools the medium and delivers it to the fitting part 21 through the same connecting pipe 4. The low temperature of the medium is then transferred to the breast through the fitting part 21. This design is suitable for relieving breast swelling or inflammation symptoms. Furthermore, this design avoids the need for frequent changes when switching between hot and cold compress modes. This design eliminates the inconvenience of switching between different devices, saving time and effort. Furthermore, this feature allows users to simultaneously perform breast pumping while applying cold or hot compresses, without interrupting the pumping process during the switch. Further, in this embodiment, the connecting pipe 4 and the breast pumping component 2 are detachably connected, and the breast pumping component 2 can be a handheld or wearable breast pump, allowing users to replace it with different types as needed. Further, this embodiment also includes a mounting housing 7 for installing and protecting the heat exchange component 3, and a power supply is installed inside the mounting housing 7. Further, in this embodiment, the fitting part 21 is made of silicone, allowing for better fit to the breast. Further, in this embodiment, two breast pumping components 2 are provided, while in other embodiments, only one breast pumping component 2 may be provided. Further, in this embodiment, pure water is preferred as the medium.

[0042] Furthermore, in some embodiments, when the medium is a liquid, the heat exchange assembly 3 is further provided with a medium reservoir for storing the medium, a pump and valve assembly for draining the connecting pipe 4, and a temperature sensor for detecting the medium temperature. The medium reservoir allows the medium flowing back from the bonding part 21 to the heat exchange assembly 3 to enter the medium reservoir first, preventing these media from directly participating in the temperature regulation process again. This is because the medium that has just flowed back still carries the temperature from the last operation. When the user switches the temperature, if these media directly enter the new temperature regulation stage, it will affect the accuracy of the newly set temperature. By first introducing the medium into the medium reservoir, its temperature can be made consistent with the system target temperature, thereby ensuring that the system regulation is accurate when switching temperatures. The accuracy of the section will not be affected by previous operations; further, in some embodiments, the heating and cooling effects can be achieved by setting heating elements and cooling elements in the heat exchange component 3, which can realize rapid heating and cooling of the medium; further, the heat exchange component 3 is provided with a cooling element for cooling and a heating element for heating. The cooling element can cool the medium by means of a compressor and a refrigerant, or by means of semiconductor refrigeration, while the heating element can directly heat the medium by means of a heating wire; further, in some embodiments, the cooling area and the heating area are separate. Therefore, a three-way valve, a control valve and a corresponding pump body are provided between the cooling area, the heating area and the connecting pipe 4 to select and control the output of the hot and cold medium. Specifically, the medium is pure water.

[0043] Furthermore, in some embodiments, the medium can also be air, and the heat exchange component 3 changes the temperature of the bonding part 21 by heating or cooling the air.

[0044] Furthermore, such as Figure 1-13 The illustration shows a breast pump assembly with hot and cold compress functions. The fitting part 21 has a fitting part cavity. The breast pump assembly body 1 also includes a medium flow channel 212 disposed in the fitting part cavity. The medium flow channel 212 is disposed on the inner or outer side of the fitting part cavity. The medium flow channel 212 includes a first medium flow channel 2121 for medium inflow, a second medium flow channel 2122 for medium outflow, and a third medium flow channel 2123 connecting the first medium flow channel 2121 and the second medium flow channel 2122.

[0045] This invention provides a cavity within the bonding portion 21, and in this embodiment, a medium flow channel 212 is located inside the cavity, providing a flow path for the medium. This enables directional flow of the hot and cold media within the cavity, resulting in more precise and controllable temperature conduction. Furthermore, by configuring the medium flow channel 212 as a first medium flow channel 2121 for medium inflow, a second medium flow channel 2122 for medium outflow, and a third medium flow channel 2123 connecting the first and second medium flow channels 2121 and 2122, the medium flow channel 212 can form a liquid exchange circulation loop with the heat exchange assembly 3 via the connecting pipe 4. This arrangement allows the medium in the heat exchange component 3 to be continuously supplied to the medium flow channel 212, while also allowing the medium that has transferred temperature in the medium flow channel 212 to flow back to the heat exchange component 3, ensuring the stability of the medium temperature in the medium flow channel 212, thereby ensuring the constant surface temperature of the bonding portion 21; further, in this embodiment, the medium flow channel 212 is directly formed inside the bonding portion 21; further, in some other embodiments, the medium flow channel 212 is embedded inside the bonding portion 21 as a component; further, in some other embodiments, the medium flow channel 212 can also be disposed outside the bonding portion 21 and closely attached to the bonding portion 21.

[0046] Furthermore, such as Figure 1-13 The invention relates to a breast pump assembly with hot and cold compress functions, wherein the first medium flow channel 2121 and the second medium flow channel 2122 are arranged in a spiral shape and are spaced apart.

[0047] In this invention, the first medium flow channel 2121 and the second medium flow channel 2122 are arranged in a spiral shape. This arrangement extends the medium flow channel 212 within a limited space, increasing the residence time of the hot and cold media within the bonding portion 21, thereby more effectively transferring temperature and ensuring the stability and continuity of temperature changes. Furthermore, the first medium flow channel 2121 and the second medium flow channel 2122 are arranged at intervals, i.e., a second medium flow channel 2122 is provided between adjacent first medium flow channels 2121. This arrangement prevents the first medium flow channels 2121 from concentrating together, thus preventing... If the temperature is too concentrated, and the first medium flow channels 2121 are concentrated together, it will cause some areas to overheat during hot compresses and some areas to be too cold during cold compresses, affecting the user's comfort and user experience. Furthermore, by setting the first medium flow channels 2121 and the second medium flow channels 2122 alternately, the hot and cold mediums can be distributed more evenly in the inner cavity of the bonding part, making the temperature of the entire bonding part 21 surface more uniform. Furthermore, since the medium in the medium flow channel 212 is constantly flowing, the temperature of the second medium flow channel 2122 has little effect on the temperature of the first medium flow channel 2121.

[0048] Furthermore, such as Figure 1-13 The illustration shows a breast pump assembly with hot and cold compress functions, wherein the connecting pipe 4 includes an output pipe 41 connecting the heat exchange component 3 and the first medium flow channel 2121, and a return pipe 42 connecting the heat exchange component 3 and the second medium flow channel 2122.

[0049] This invention establishes a loop for the cold or hot medium between the milk pumping assembly 2 and the heat exchange assembly 3 by setting up an output pipe 41 and a return pipe 42. This allows the cold or hot medium to directly enter the first medium flow channel 2121 through the output pipe 41, thereby transferring the temperature to the surface of the contact part 21 that contacts the breast, providing the required cold or hot compress effect. At the same time, the medium that has completed the temperature exchange returns to the heat exchange assembly 3 through the return pipe 42 for readjustment, ensuring the continuous operation of the entire system. This design ensures the continuity and stability of temperature regulation, thereby ensuring the temperature stability of the contact part 21.

[0050] Furthermore, such as Figure 1-13 The illustration shows a breast pump assembly with hot and cold compress functions. The breast pump assembly 2 further includes a milk suction part 22 for suctioning milk and a connecting assembly 23 connected to the milk suction part 22. The fitting part 21 is provided on the milk suction part 22. The connecting assembly 23 is also provided with a first docking end 231 connecting the output pipe 41 and the first medium flow channel 2121, and a second docking end 232 connecting the recovery pipe 42 and the second medium flow channel 2122.

[0051] The milk suction assembly 2 of this invention includes a milk suction part 22 for suctioning milk and a connecting assembly 23 connected to the milk suction part 22. The milk suction part 22 and the connecting assembly 23 are detachably connected, allowing users to quickly replace or clean the components as needed. Furthermore, the connecting assembly 23 includes a first docking end 231 for connecting the output pipe 41 to the first medium flow channel 2121, and a second docking end 232 for connecting the recovery pipe 42 to the second medium flow channel 2122. The output pipe 41 is directly inserted into the first docking end 23. 1. The connection is made by directly inserting the recovery pipe 42 into the second docking end 232, ensuring a stable connection between the connecting pipe 4 and the connecting component 23. Furthermore, by connecting the connecting pipe 4 to the connecting component 23, the user does not need to disassemble the connecting pipe 4 when the milk pump 22 needs to be disassembled for cleaning, avoiding sealing problems caused by prolonged disassembly and assembly. Furthermore, in some embodiments, the output pipe 41 and the recovery pipe 42 are PU tubes, which have a certain degree of elasticity and can form an effective seal when docked with the first docking end 231 and the second docking end 232 respectively.

[0052] Furthermore, such as Figure 1-13 The illustration shows a breast pump assembly with hot and cold compress functions. The fitting part 21 has a fitting surface 211 that fits the breast, and a first connecting end 221 and a second connecting end 222 located on the side away from the fitting surface 211. The first connecting end 221 is connected to a first medium flow channel 2121, and the second connecting end 222 is connected to a second medium flow channel 2122. The first docking end 231 has a first connecting hole 2311 for the first connecting end 221 to be inserted, and the second docking end 232 has a second connecting hole 2321 for the second connecting end 222 to be inserted.

[0053] This invention provides a first connecting end 221 and a second connecting end 222 on the side of the fitting part 21 away from the fitting surface 211, and provides a first connecting hole 2311 and a second connecting hole 2321 on the first mating end 231 and the second mating end 232 of the connecting component 23, respectively. By inserting the first connecting end 221 into the first connecting hole 2311 and the second connecting end 222 into the second connecting hole 2321, not only is the milk pumping part 22 and the connecting component 23 connected, but also a tight and rapid connection is achieved between the medium flow channel 212 and the connecting pipe 4. This arrangement not only ensures the sealing of the medium flow path and avoids leakage problems, but also effectively simplifies the assembly process of the milk pumping part 22 and the connecting component 23, allowing users to perform daily care and cleaning more easily. Furthermore, in some embodiments, the first connecting end 221 and the second connecting end 222 are made of silicone material, so that they can form an effective seal when they fit with the first connecting hole 2311 and the second connecting hole 2321.

[0054] Furthermore, such as Figure 1-13 The illustration shows a breast pump assembly with hot and cold compress functions. The main body 1 of the breast pump assembly also includes an air pump assembly 5, and the breast pump assembly 2 is also provided with a negative pressure chamber 6. The connecting pipe 4 includes a negative pressure pipe 43 that connects the air pump assembly 5 and the negative pressure chamber 6.

[0055] This invention connects the air pump assembly 5 and the negative pressure chamber 6 through a negative pressure pipeline 43, so that the negative pressure generated by the air pump assembly 5 can act on the negative pressure chamber 6, thereby achieving the effect of the milk pump assembly 2 sucking up the milk; furthermore, the air pump assembly 5 in this embodiment can also adjust the milk pumping force according to the user's needs, ensuring that the milk pumping process is both efficient and comfortable; furthermore, the air pump assembly 5 is installed in the mounting housing 7; furthermore, a solenoid valve is also provided between the air pump assembly 5 and the negative pressure chamber 6, and the solenoid valve is installed in the mounting housing 7.

[0056] Furthermore, such as Figure 1-13The invention illustrates a breast pump assembly with hot and cold compress functions. The breast pumping part 22 is further provided with a deformable part 223 connected to the side of the fitting part 21 away from the fitting surface 211. The deformable part 223 has a breast pumping channel 2231 inside. The connecting component 23 has a connecting component inner cavity 234 into which the deformable part 223 extends. The deformable part 223 and the inner wall of the connecting component inner cavity 234 form the negative pressure cavity 6.

[0057] This invention achieves a milk suction effect by extending the deformable part 223 into the inner cavity 234 of the connecting component and forming a negative pressure cavity 6 with the inner wall of the inner cavity 234 of the connecting component. When the air pump assembly 5 provides negative pressure to the negative pressure cavity 6 through the negative pressure pipeline 43, the negative pressure acts on the deformable part 223, causing the deformable part 223 to deform. This deformation forms an effective suction force in the milk suction channel 2231, thereby efficiently sucking up the milk. This design effectively simplifies the milk suction operation process.

[0058] Furthermore, such as Figure 1-13 The diagram shows a breast pump assembly with hot and cold compress functions, wherein the connecting assembly 23 is further provided with a third docking end 233 that cooperates with the negative pressure pipeline 43, and the third docking end 233 is provided with a third docking hole 2331 that communicates with the negative pressure chamber 6.

[0059] This invention simplifies the connection structure between the air pump assembly 5 and the negative pressure chamber 6 by providing a third docking end 233 on the connecting component 23 to cooperate with the negative pressure pipeline 43, and providing a third docking hole 2331 on the third docking end 233 to communicate with the negative pressure chamber 6. This design ensures stable transmission of negative pressure. Furthermore, this design allows users to install and disassemble the pipeline more conveniently. Furthermore, by connecting the negative pressure pipeline 43 and the third docking end 233, and by providing the third docking hole 2331 on the third docking end 233 to communicate with the negative pressure chamber 6, the pipeline used to transmit hot and cold media is separated from the pipeline that creates negative pressure in the negative pressure chamber 6, thereby achieving simultaneous hot and cold compresses and breast milk pumping. Furthermore, in some embodiments, the negative pressure pipeline 43 is a PU tube, which has a certain degree of elasticity and can form a sealing fit with the third docking end 233, thereby improving the sealing and reliability of the pipeline connection and avoiding leakage problems.

[0060] Furthermore, such as Figure 1-13 The invention illustrates a breast pump assembly with hot and cold compress functions. The breast pump assembly 2 further includes a storage assembly 24 for storing breast milk, and the breast pump channel 2231 is provided with a liquid outlet 22311 communicating with the inner cavity of the storage assembly 24.

[0061] This invention provides a storage component 24 for storing milk in the milk pumping assembly 2, and a liquid outlet 22311 communicating with the inner cavity of the storage component 24 in the milk pumping channel 2231. This design not only achieves a seamless connection from milk pumping to storage, reducing intermediate steps and avoiding unnecessary contact between the milk and air, thus ensuring the hygiene and safety of milk storage; furthermore, this design allows users to complete the entire process of milk pumping and milk storage without additional operation, improving convenience and efficiency.

[0062] Furthermore, such as Figure 1-13 The breast pump assembly shown has hot and cold compress functions. The connecting component 23 is located near the fitting part 21 and is provided with an abutting part 236 that abuts against the fitting part 21. The fitting part 21 is flared and the abutting part 236 is adapted to the shape of the fitting part 21.

[0063] In this invention, the abutting part 236 and the fitting part 21 are adapted to each other in shape. When the first connecting end 221 is inserted into the first connecting hole 2311 and the second connecting end 222 is inserted into the second connecting hole 2321, the abutting part 236 and the fitting part 21 fit together. When the negative pressure chamber 6 generates negative pressure, since the fitting part 21 in this embodiment is made of silicone, the fitting part 21 will tightly abut against the abutting part 236 due to the adsorption effect, thereby sealing the negative pressure chamber 6 and ensuring the milk suction effect.

[0064] Example 2:

[0065] Furthermore, such as Figure 1-13 The diagram shows a breast pump assembly with hot and cold compress functions, wherein the connecting assembly 23 is further provided with a docking interface 235 connected to the storage assembly 24, and the liquid outlet 22311 is provided with a one-way valve assembly 22312.

[0066] This invention improves ease of use and equipment maintenance by providing a connection interface 235 on the connecting component 23 for connection with the storage component 24, and by detachably connecting the connecting component 23 to the storage component 24 via the connection interface 235. Furthermore, the connection component 23 is sealed to the storage component 24 via the connection interface 235, thus preventing leakage of emulsion from the connection between the connecting component 23 and the storage component 24. Furthermore, by providing a one-way valve assembly 22312 at the outlet 22311, efficient transfer of emulsion from the milk suction channel 2231 to the storage component 24 is achieved, ensuring that the emulsion can only flow unidirectionally to the storage component 24, preventing emulsion backflow or leakage.

[0067] Example 3:

[0068] Furthermore, such as Figure 1-16 The illustration shows a breast pump assembly with hot and cold compress functions, wherein the liquid outlet 22311 is detachably connected to the storage assembly 24.

[0069] This invention features a detachable connection between the outlet 22311 and the storage component 24, allowing users to easily remove the storage component 24 from the milk pumping component 2 for convenient cleaning and maintenance. It also allows users to quickly replace the storage component 24 when needed, ensuring the hygiene and safety of the milk. Furthermore, the detachable and sealed connection between the outlet 22311 and the storage component 24 ensures that the milk flows smoothly and leak-free into the storage component 24. This design allows users to remove the storage component 24 after each use for cleaning and disinfection, effectively preventing bacterial growth. Moreover, this design also allows users to replace the storage component 24 with different ones according to different needs, thus better meeting personalized requirements.

[0070] 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.
