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

[0002] With the popularization of breastfeeding and the fast pace of modern life, breast pumps have become an essential tool for many breastfeeding women. People use breast pumps to efficiently express and store breast milk for subsequent feeding of their babies.

[0003] Existing breast pumps have complex structures, and the disassembly and assembly of various components are complicated, time-consuming, and inefficient, making them inconvenient for pumping milk and cleaning, resulting in a poor user experience. To reduce the number of parts, some breast pumps integrate the horn cover, suction bowl, and spout valve into a single unit. However, this one-piece structure prevents users from selecting different materials for the horn cover and suction bowl based on their actual needs. Different materials vary in cost and performance, which is not conducive to cost savings.

[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 wearable breast pump, and the technical solution adopted is as follows: A wearable breast pump includes a front shell for conforming to the breast, a rear shell for detachably connected to the front shell, and a main unit for providing a negative pressure source. The front shell includes an opening, a first milk outlet, and a milk suction channel. The milk suction channel extends from the opening toward the first milk outlet. The rear shell and the front shell are connected to form a milk storage chamber. A suction bowl is provided on the outside of the milk suction channel. The suction bowl surrounds and fits against the outer wall of the milk suction channel. The suction bowl is provided with a second milk outlet that communicates with the first milk outlet and a one-way valve connected to the second milk outlet, so that milk enters the milk storage chamber through the one-way valve.

[0006] Furthermore, the front shell of the milk bowl is made of thermoplastic material, and the suction bowl and one-way valve are both made of flexible material, and the suction bowl and one-way valve are integrally formed.

[0007] Furthermore, the main unit includes a breast pump, an installation compartment is provided at the bottom of the rear shell of the milk bowl, an installation mechanism is provided between the breast pump and the installation compartment, and the breast pump is detachably connected to the bottom of the rear shell of the milk bowl through the installation mechanism.

[0008] Furthermore, a mounting groove is provided on the top of the front shell of the milk bowl on the side away from the rear shell of the milk bowl, and the main unit assembly includes a controller that is detachably mounted on the mounting groove and is used to control the operating status of the milk pumping main unit.

[0009] Furthermore, the installation mechanism includes an installation slide rail located on the side of the rear shell of the milk bowl away from the front shell of the milk bowl, and an installation groove located on the milk pumping unit and slidably connected to the installation slide rail.

[0010] Furthermore, the opening is provided with a removable liner made of a flexible material.

[0011] Furthermore, the front shell of the milk bowl includes an observation section located above the opening and a deformation section located on the outer wall of the milk suction channel. The observation section, the deformation section, and the suction bowl are all made of transparent material.

[0012] Furthermore, a sealing ring is provided between the front shell and the rear shell of the milk bowl.

[0013] Furthermore, a handle is formed between the bottom of the rear shell of the milk bowl and / or the bottom of the milk pump unit.

[0014] Furthermore, the handle includes a first extension located at the bottom of the rear shell of the milk bowl and a second extension located at the bottom of the breast pump, both of which are arc-shaped.

[0015] The beneficial effects of this utility model are as follows: This invention saves internal space in the breast pump by setting a suction bowl that fits the milk suction channel on the outside of the milk suction channel. The suction bowl and the front shell of the milk bowl are set separately, which allows users to choose different materials to make the front shell of the milk bowl and the suction bowl separately.

[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 8 A wearable breast pump is shown, including a front shell 1 for conforming to the breast, a rear shell 2 detachably connected to the front shell 1, and a main unit 4 for providing a negative pressure source. The front shell 1 includes an opening 14, a first milk outlet 111, and a milk suction channel 11. The milk suction channel 11 extends from the opening 14 toward the first milk outlet 111. The rear shell 2 and the front shell 1 are connected to form a milk storage chamber 12. The milk suction channel 11 is provided with a suction bowl 3 on the outside. The suction bowl 3 surrounds and fits the outer wall of the milk suction channel 11. The suction bowl 3 is provided with a second milk outlet 32 ​​that communicates with the first milk outlet 111, and a one-way valve 31 connected to the second milk outlet 32, so that milk enters the milk storage chamber 12 through the one-way valve 31.

[0022] This invention saves internal space in the breast pump by setting a suction bowl that fits the milk suction channel on the outside of the milk suction channel. The suction bowl and the front shell of the milk bowl are set separately, which allows users to choose different materials to make the front shell of the milk bowl and the suction bowl separately. While ensuring the quality and performance of the equipment, it helps to reduce production costs.

[0023] Furthermore, the front shell 1 and the rear shell 2 of the milk bowl are detachably connected, which makes it convenient for users to clean and maintain the internal components of the breast pump. After a period of use, users can easily disassemble the front shell 1 and the rear shell 2 of the milk bowl to thoroughly clean the milk storage chamber 12, the milk suction channel 11, the suction bowl 3 and other components, which helps to ensure the hygiene of the breast pump.

[0024] Optionally, the front shell 1 and the rear shell 2 of the milk bowl can be connected by threaded connection, snap-fit ​​connection or other connection methods.

[0025] Furthermore, such as Figures 1 to 8 The front shell 1 of the milk bowl shown is made of thermoplastic material, and the suction bowl 3 and the one-way valve 31 are both made of flexible material. The suction bowl 3 and the one-way valve 31 are integrally formed.

[0026] Furthermore, the suction bowl 3 and the one-way valve 31 are integrally molded. Compared with the traditional separate installation of the suction bowl and one-way valve, the integral molding helps to reduce the number of parts, making the overall structure of the breast pump simpler. This helps to reduce the difficulty of managing and assembling parts during the production process. In addition, the integral molding design avoids the extra space required for separate installation of the suction bowl 3 and the one-way valve 31, so that the internal space of the breast pump can be effectively utilized, thus saving the internal space of the breast pump.

[0027] Furthermore, the one-piece molded structure helps reduce the connection gap between the suction bowl 3 and the one-way valve 31, thereby improving the sealing performance of the breast pump. Better sealing performance helps maintain a stable negative pressure environment, making the milk pumping process smoother and improving milk pumping efficiency. At the same time, it effectively reduces the risk of milk leakage.

[0028] Preferably, the front shell 1 of the breast pump is made of PP (polypropylene) or PPSU (polyphenyl sulfone). PP is a food-grade material that is non-toxic, odorless, and meets the safety standards for maternal and infant products, allowing it to come into direct contact with breast milk and skin. Secondly, PP material has good high-temperature resistance and can withstand high-temperature sterilization, which helps ensure the hygiene of the breast pump during use. Furthermore, PPSU has excellent high-temperature resistance, high strength, good toughness, and is durable and resistant to breakage, even in the event of frequent use or accidental drops.

[0029] Preferably, both the suction bowl 3 and the one-way valve 31 are made of silicone material. Silicone has excellent sealing performance, which can effectively prevent air leakage and milk leakage, which helps to ensure the stable suction of the breast pump and effectively improve the milk pumping efficiency. Secondly, silicone material has good flexibility and elasticity, which can fit closely to the breast, provide a comfortable user experience, and reduce the pressure on the breast.

[0030] Furthermore, a proper combination of PP and silicone materials can help reduce production costs while ensuring equipment quality and performance.

[0031] Furthermore, such as Figures 1 to 8 The main unit 4 shown includes a breast pump 41, and an installation compartment 21 is provided at the bottom of the milk bowl rear shell 2. An installation mechanism is provided between the breast pump 41 and the installation compartment 21. The breast pump 41 is detachably connected to the bottom of the milk bowl rear shell 2 through the installation mechanism.

[0032] Furthermore, during the use of the breast pump, the front shell 1, the back shell 2, and the suction bowl 3 will directly contact the breast milk, which can easily leave residual breast milk and breed bacteria. The detachable connection allows users to easily separate the back shell 2 from the breast pump unit 41, thereby facilitating thorough cleaning and sterilization of the breast bowl part and ensuring hygiene.

[0033] Furthermore, the bottom mounting compartment 21 makes full use of the lower space of the milk bowl back shell 2, avoiding the extra space occupation caused by the external placement of the milk pumping unit 41, and improving space utilization.

[0034] Furthermore, when the breast pump unit 41 or the milk bowl malfunctions, the detachable connection allows users to quickly replace the damaged parts without replacing the entire breast pump, which helps reduce maintenance costs.

[0035] Furthermore, when the breast pump is not in use, the detachable connection allows users to store the breast pump unit 41 and the milk bowl back cover 2 separately, which helps to reduce the overall space occupied by the breast pump.

[0036] Optionally, in some embodiments, the installation mechanism includes an external thread located on the installation chamber 21 and an internal thread located on the breast pump 41, so that the breast pump 41 and the installation chamber 21 are tightly threadedly connected by rotating the breast pump 41.

[0037] Optionally, in some embodiments, the installation mechanism includes an elastic buckle located in the installation compartment 21 and a slot located on the breast pump host 41. After aligning the breast pump host 41 with the installation compartment 21, the user presses down to make the buckle snap into the slot, thus connecting the two. When disassembling, the user presses down on the buckle to disengage it from the slot, thereby separating the breast pump host 41 and the milk bowl back cover 2.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the milk bowl back shell 2 and the milk pumping unit 41 are slidably connected by the mounting slide rail 51 and the mounting groove 52.

[0039] Specifically, the breast pump unit 41 integrates key components such as an air pump, battery, solenoid valve, and PCBA. The air pump generates negative pressure to power the pumping process; the battery provides stable power to the entire unit, ensuring that the breast pump is not limited by power supply during use, allowing users to use it anytime, anywhere; the solenoid valve is used to precisely control the magnitude and switching of negative pressure, thereby realizing suction adjustment and pause functions during the pumping process; the PCBA integrates control chips, sensors, and circuits, enabling intelligent control of the pumping process, such as adjusting suction mode, controlling pumping time, and monitoring battery level.

[0040] Furthermore, such as Figures 1 to 8 The top of the front shell 1 of the milk bowl shown is provided with a mounting groove 13 on the side away from the rear shell 2 of the milk bowl. The main unit assembly 4 includes a controller 42 that is detachably mounted on the mounting groove 13 and is used to control the operating state of the milk pumping main unit 41.

[0041] Furthermore, the controller 42 is mounted on the mounting slot 13 of the front shell 1 of the milk bowl, so that the user can easily touch and operate it during the milk feeding process. When feeding, the user's hand will usually naturally approach the milk bowl, at which time the controller 42 can be easily adjusted, such as adjusting the feeding mode, intensity and time parameters, without having to move the hand significantly or look for other control devices, thus improving the convenience and efficiency of operation.

[0042] Furthermore, by mounting the controller 42 on the mounting slot 13 of the front shell of the milk bowl 1, the overall structure of the breast pump becomes more compact, reducing additional space occupation. Secondly, the design of the mounting slot 13 allows the controller 42 to be integrated with the front shell of the milk bowl, making the appearance of the breast pump more concise and beautiful.

[0043] Optionally, the controller 42 can be installed on the mounting slot 13 using connection methods such as threaded connection, snap-fit ​​connection, slot connection, magnetic connection, etc.

[0044] Preferably, the controller 42 is located on the top of the front shell 1 of the milk bowl, so that the user can naturally see the operation buttons of the controller while using the breast pump, making it easy for the hand to reach and operate.

[0045] Furthermore, such as Figures 1 to 8 The installation mechanism shown includes an installation slide rail 51 located on the side of the rear shell 2 of the milk bowl away from the front shell 1 of the milk bowl, and an installation groove 52 located on the milk pumping unit 41 and slidably connected to the installation slide rail 51.

[0046] Furthermore, the sliding connection makes the connection and disassembly between the breast pump 41 and the rear shell of the milk bowl 2 very simple and quick. Users only need to push the breast pump 41 in or pull it out along the mounting rail 51 to complete the installation or disassembly, without the need for complicated rotation or pressing actions.

[0047] Furthermore, the installation slide rail 51 and installation groove 52 provide a good limiting function to ensure that the breast pump host 41 will not loosen or fall off due to accidental collision or shaking during use; secondly, the sliding connection can ensure that the interface between the breast pump host 41 and the milk bowl back shell 2 is accurately aligned, avoiding problems such as air leakage or loose connection caused by improper installation.

[0048] Furthermore, the installation of the slide rail 51 and the installation groove 52 can hide the connection interface at the connection between the breast pump host 41 and the milk bowl back shell 2, reducing exposed parts and improving the overall aesthetics of the breast pump.

[0049] Furthermore, there are two mounting rails 51, each of which is L-shaped. The two L-shaped mounting rails 51 can fix the breast pump 41 from multiple directions. The L-shaped structure allows the rails to not only limit the breast pump 41 in the horizontal direction, but also provide support and constraint in the vertical direction. Compared with a single-direction fixing method, this multi-directional fixing can effectively prevent the breast pump 41 from shaking or shifting back and forth, left and right, and up and down during use. This greatly enhances the stability of the connection between the breast pump 41 and the milk bowl back shell 2, ensures the accuracy of the relative positions between the components of the breast pump during operation, and guarantees the milk pumping effect.

[0050] Furthermore, such as Figures 1 to 8 The opening 14 shown is provided with a removable inner liner 15, which is made of a flexible material.

[0051] Furthermore, the inner liner 15 is made of a flexible material, such as silicone or rubber, which can better conform to the shape of the breast, reduce pressure on the breast, and provide a more comfortable user experience; secondly, the soft inner liner 15 can reduce friction between the front shell 1 of the breast cup and the breast, avoiding skin discomfort or damage caused by prolonged use.

[0052] Furthermore, since the inner lining 15 has a certain degree of elasticity, it can adapt to different breast shapes and sizes, ensuring a good sealing effect under various conditions.

[0053] Furthermore, the inner lining 15 can be disassembled and washed separately, preventing dirt and grime from accumulating at the opening 14, reducing the risk of bacterial growth, and helping to meet the hygiene requirements of maternal and infant products.

[0054] Furthermore, such as Figures 1 to 8 The milk bowl front shell 1 shown includes an observation part 16 located above the opening 14 and a deformation part 17 located on the outer wall of the milk suction channel 11. The observation part 16, the deformation part 17 and the suction bowl 3 are all made of transparent material.

[0055] Furthermore, the observation section 16, the deformation section 17, and the suction bowl 3 are all made of transparent material, so that users can clearly see the fit between the breast and the suction bowl 3 and the flow of milk. During the milk pumping process, users can promptly detect problems such as milk blockage or insufficient breast fit, and make adjustments based on the observed conditions to ensure a smooth milk pumping process and improve milk pumping efficiency.

[0056] Furthermore, transparent components provide users with good visual feedback, making them feel more at ease when using the breast pump. Users can see the working status of the breast pump and the condition of their breasts, reducing tension and anxiety caused by not being able to see, thereby improving the comfort of use.

[0057] Furthermore, the transparent observation section 16, deformation section 17, and suction bowl 3 allow users to easily observe the internal workings of the breast pump. If any problems such as component damage or air leakage occur during the operation of the breast pump, users can detect them in time through the transparent sections, thus avoiding the breast pump failing to work properly or causing damage to the breasts due to the failure to detect the fault in time.

[0058] Furthermore, such as Figures 1 to 8 A sealing ring 6 is provided between the front shell 1 and the rear shell 2 of the milk bowl shown.

[0059] Furthermore, the sealing ring 6 can effectively fill the tiny gap between the front shell 1 and the rear shell 2 of the milk bowl, ensuring a tight connection between the two and preventing air leakage.

[0060] Furthermore, the sealing ring 6 can prevent milk from leaking from the connection between the front shell 1 and the rear shell 2 of the milk bowl, avoiding milk seepage that could contaminate the milk pump 41 or other components, and ensuring hygiene and safety during use.

[0061] Furthermore, the sealing ring 6 is made of food-grade materials, such as silicone or food-grade rubber, which is non-toxic and odorless, meets the hygiene standards for maternal and infant products, and ensures that the parts in contact with breast milk are safe and reliable.

[0062] Furthermore, such as Figures 1 to 8 A latch 7 is formed between the bottom of the rear shell 2 of the milk bowl and / or the bottom of the milk pump 41.

[0063] Furthermore, after a period of use, the breast pump needs to be disassembled for cleaning or maintenance of components such as the milk bowl and the main pump 41. The handle 7 provides a convenient position for the user to apply force. The user can use their fingers to hold this position and easily separate the back shell 2 of the milk bowl from the main pump 41, avoiding the situation where it is difficult to find a point of leverage, which may lead to disassembly difficulties or damage to the components. Similarly, during installation, the handle 7 also helps the user to accurately align the back shell 2 of the milk bowl with the main pump 41 and install it in place.

[0064] Furthermore, when disassembling and installing breast pump components, if there is no suitable point of leverage, the hand can easily slip off the components, which may cause the breast pump to fall and be damaged, or even injure the user or surrounding objects. The design of the handle increases the friction and stability between the hand and the breast pump components, reduces the risk of slippage, and ensures safety during use.

[0065] Preferably, both the bottom of the milk bowl back shell 2 and the bottom of the milk pump host 41 are provided with a handle 7, which allows the user to use multiple fingers to hold the two positions at the same time, forming a more stable grip.

[0066] Furthermore, such as Figures 1 to 8 The handle 7 shown includes a first extension 71 located at the bottom of the milk bowl rear shell 2 and a second extension 72 located at the bottom of the milk pump host 41. Both the first extension 71 and the second extension 72 are arc-shaped.

[0067] Furthermore, the curved design naturally conforms to the shape of the user's fingers. Especially when the user grips the grip 7 with their fingers, the curved structure can better distribute the pressure on the fingers and reduce fatigue caused by prolonged use. Secondly, the curved first extension 71 and second extension 72 provide a more comfortable grip experience. Users can choose the appropriate grip position according to their hand size and usage habits, further improving the comfort of use.

[0068] Furthermore, the curved design increases the contact area between the user's fingers and the handle 7, thereby improving grip stability and reducing instability of the breast pump caused by hand slippage.

[0069] Furthermore, the curved design reduces sharp edges on the device surface, lowering the risk of scratches or cuts caused by accidental collisions and further improving product safety.

[0070] The implementation method of Example 2 is as follows: The difference between Embodiment 2 and Embodiment 1 is that the controller 42 is located on the side of the front shell 1 of the milk bowl, which helps to make full use of the space on the side of the front shell 1 of the milk bowl, making the overall structure of the breast pump more compact and reducing the space occupied.

[0071] The implementation method of Example 3 is as follows: The difference between Example 3 and Example 1 is that the controller 42 is located at the bottom of the front shell 1 of the milk bowl. During daily use and carrying, the controller is not easily touched accidentally, thus avoiding situations such as the breast pump suddenly starting or stopping or abnormal changes in suction caused by accidental touch.

[0072] The implementation method of Example 4 is as follows: The difference between Example 4 and Example 1 is that the front shell 1 of the milk bowl is made of TPE material. TPE material has the elasticity of rubber and the processing properties of plastic. It is soft in texture and feels comfortable when in contact with the skin. It can better fit the breast and reduce pressure and discomfort on the breast.

[0073] The implementation method of Example 5 is as follows: The difference between Example 5 and Example 1 is that both the suction bowl 3 and the one-way valve 31 are made of natural rubber. Natural rubber has extremely high elasticity and can quickly respond to changes in negative pressure during milk expression, generating strong and stable suction to effectively promote milk discharge.

[0074] The implementation method of Example 6 is as follows: The difference between Example 6 and Example 1 is that the handle 7 is located at the bottom of the milk bowl back shell 2. After the breast pump has been used for a period of time, milk will remain inside the milk bowl back shell, which needs to be disassembled and cleaned. The presence of the handle 7 provides a point of leverage for the user. The user can use their fingers to hold this position and easily remove the milk bowl back shell from the breast pump body without damaging the milk bowl back shell or other parts due to difficulty in applying force.

[0075] The implementation method of Example 7 is as follows: The difference between Embodiment 7 and Embodiment 1 is that the handle 7 is located at the bottom of the breast pump host 41. The breast pump host 41 usually needs to be disassembled regularly for cleaning or maintenance. With the handle 7 located at the bottom of the host, the user can easily use their fingers to hold the position and conveniently remove the host from the back shell 2 of the milk bowl or install it back.

[0076] 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.
