[0036] Further, the suction bowl 2 is integrally formed with the breast pumping channel 13, the structure is more compact, and the overall stability is enhanced, when the suction bowl 2 elastically deforms during the operation of the breast pump, the breast pumping channel 13 can be more stably driven to form a negative pressure, and the unstable situation of the breast pumping effect caused by loose parts or insecure connection is reduced.

[0037] Further, the suction bowl 2 is integrally formed with the breast pumping channel 13, the structure is more compact, and the overall stability is enhanced, when the suction bowl 2 elastically deforms during the operation of the breast pump, the breast pumping channel 13 can be more stably driven to form a negative pressure, and the unstable situation of the breast pumping effect caused by loose parts or insecure connection is reduced.

[0038] Optionally, the outer shell 3 can be installed on the side of the breast pump 1 away from the opening 11 by means of a threaded connection.

[0039] Optionally, the outer shell 3 can be installed on the side of the breast shield 1 away from the opening 11 by means of a snap-fit ​​connection.

[0040] Optionally, the outer shell 3 can be installed on the side of the breast shield 1 away from the opening 11 by means of a slot connection.

[0041] Furthermore, such as Figures 1 to 9 The main housing 51 shown is provided with a first opening 511, the outer housing 3 is provided with a second opening 312, and the air pressure chamber 41 communicates with the negative pressure mechanism 52 through the first opening 511 and the second opening 312.

[0042] Specifically, the main unit 5 includes a main unit housing 51 and a negative pressure mechanism 52 located inside the main unit housing 51. The main unit 5 is the core part of the breast pump that generates negative pressure. The negative pressure mechanism 52 communicates with the air pressure chamber 41 through the first opening 511 on the main unit housing 51 and the second opening 312 on the outer shell 3, which helps to ensure that the negative pressure can be efficiently transmitted to the air pressure chamber 41.

[0043] Furthermore, such as Figures 1 to 9 The main unit housing 51 shown is integrally formed.

[0044] Furthermore, the one-piece molded main body housing 51 has no welded or spliced ​​seams, reducing potential weak points and improving the overall structural strength and durability; secondly, the one-piece molded structure can better withstand external pressure and impact, ensuring that it will not be damaged by accidental collisions during use.

[0045] Furthermore, the unibody manufacturing method reduces assembly steps and the number of required parts, thereby simplifying the entire manufacturing process, which not only reduces production costs but also helps to improve production efficiency.

[0046] Furthermore, since the one-piece molded main unit housing 51 has no seams, it reduces the risk of air leakage caused by improper assembly or component aging, which helps to ensure that the breast pump maintains a stable negative pressure environment during use.

[0047] Furthermore, such as Figures 1 to 9 The negative pressure mechanism 52 shown includes a drive power supply 521, a drive motor 522 connected to the drive power supply 521, and a negative pressure pump 523 connected to the drive motor 522. The output end of the negative pressure pump 523, the first opening 511, and the second opening 312 are located on the same straight line.

[0048] Specifically, the output end of the negative pressure mechanism 52, the first opening 511, and the second opening 312 are located on the same straight line, so that the negative pressure can be efficiently transmitted to the air pressure chamber 41 along this straight line. This helps to reduce the loss and dispersion of negative pressure during transmission, ensuring that the negative pressure can fully act on the suction bowl 2 and the milk suction channel 13, thereby improving milk suction efficiency. Secondly, the straight-line arrangement helps to reduce the turning and obstruction of airflow during transmission, which helps to reduce airflow resistance, helps to maintain the stable output of the negative pressure mechanism 52, and reduces energy consumption and noise caused by airflow resistance.

[0049] Furthermore, the drive power supply 521 provides power to the drive motor 522, which drives the negative pressure pump 523 to work, and can continuously and stably generate negative pressure, which helps to ensure that the breast pump can provide a stable negative pressure environment when it is working.

[0050] Optionally, the operating state of the negative pressure pump 523 can be precisely adjusted by controlling the drive motor 522, so that the intensity and variation of the negative pressure can be adjusted according to the user's actual needs, which helps to simulate the effect of natural sucking.

[0051] Furthermore, such as Figures 1 to 9 The breast pump 1 shown includes an extension 14 extending away from the opening 11, and the main housing 51 is provided with a clearance groove 512 on the side near the opening 11 for the outer wall of the extension 14 to extend into.

[0052] Furthermore, by extending the extension 14 into the clearance groove 512, the breast pump 1 and the main unit housing 51 can fit more tightly together, improving the stability of the connection; secondly, the extension 14 extending into the clearance groove 512 can form a tighter contact, which helps to reduce assembly gaps.

[0053] Furthermore, the extension 14 is designed to make the connection between the milk suction channel 13 and the suction bowl 2 more secure, effectively preventing the suction bowl 2 from shifting or deforming under negative pressure. At the same time, the extension 14 increases the connection area between the suction bowl 2 and the outer shell 3 and the mounting shell 311, thereby improving the stability of the entire breast pump structure.

[0054] The outer shell 3 is provided with a first clearance notch 32 for the extension 14 to extend into, and the mounting shell 311 is provided with a second clearance notch 3111 for the extension 14 to extend into. The first clearance notch 32 and the second clearance notch 3111 are respectively configured to cooperate with the extension 14 so that the suction bowl 2 and the mounting shell 311 can be precisely aligned during assembly, which helps to reduce the adjustment steps in the assembly process and effectively improves the efficiency and accuracy of assembly.

[0055] Optionally, the cross-section of the first clearance notch 32 is "U" shaped. The "U" shaped cross-section structure has good rigidity and bending resistance, which can effectively prevent deformation caused by external forces and ensure the stability of the outer shell 3 structure.

[0056] Optionally, the cross-section of the second clearance notch 3111 is U-shaped. The U-shaped cross-section design can increase the structural strength of the second clearance notch 3111, making it less prone to deformation or damage when subjected to external forces. This helps ensure that the second clearance notch 3111 maintains the integrity of its shape and function during long-term use. Secondly, the U-shaped cross-section of the second clearance notch 3111 can provide better guidance, making it easier for the extension 14 to extend into and be fixed in the corresponding position. This helps to simplify the assembly process, improve assembly efficiency, and reduce the failure rate caused by improper assembly.

[0057] Furthermore, such as Figures 1 to 9 The avoidance groove 512 shown is arc-shaped.

[0058] Specifically, the arc-shaped design makes the contact surface between the extension 14 and the relief groove 512 smoother, reducing local stress concentration and thus improving the stability and durability of the connection; secondly, the arc-shaped structure has better resistance to deformation, and can maintain the stability of its shape even when subjected to external pressure or impact, reducing damage caused by stress concentration.

[0059] Furthermore, such as Figures 1 to 9 The outer shell 3 shown is provided with a mounting shell 311 extending toward the milk suction channel 13. A mounting groove 23 is provided between the extension 14 and the suction bowl 2 for the mounting shell 311 to extend into. When the mounting shell 311 extends into the mounting groove 23, the suction bowl 2 and the mounting shell 311 surround and form an air pressure chamber 41.

[0060] Furthermore, through the plug-in connection, users can easily install the suction bowl 2 onto the mounting housing 311, or quickly disassemble it when cleaning or replacement is needed, which simplifies the operation steps and helps improve the user experience.

[0061] Furthermore, the interlocking structure provides a secure connection, ensuring that the suction bowl 2 will not loosen or fall off during use, thus guaranteeing the stability and safety of milk expression. Secondly, the secure connection can effectively reduce air leakage caused by loose connections during milk expression, ensuring stable negative pressure and improving milk expression efficiency.

[0062] Optionally, the suction bowl 2 and the milk suction channel 13 are both made of silica gel material, which has excellent flexibility and elasticity, can better fit the shape of the breast, and can maintain good sealing even on slightly curved or irregular surfaces, so that the suction bowl 2 can more evenly distribute negative pressure during use, reducing the problem of excessive local pressure.

[0063] Further, as shown in the installation groove 23, a plurality of elastic sealing strips 231 are arranged on the end of the installation shell 311. Figures 1 to 9

[0064] Further, the elastic sealing strip 231 can fill the small gap between the installation groove 23 and the installation shell 311, effectively preventing air leakage from these gaps, helping to maintain the negative pressure state of the air pressure chamber 41, and ensuring the smooth progress of the breast pump process.

[0065] Further, the elastic sealing strip 231 not only plays a sealing role, but also to a certain extent, increases the connection strength between the installation groove 23 and the installation shell 311, helps to prevent loosening or falling off due to external forces during use, and improves the structural stability of the entire breast pump.

[0066] Further, as shown in the installation groove 23, a plurality of elastic sealing strips 231 are arranged on the end of the installation shell 311. Figures 1 to 9

[0067] Further, through the first deformation part 21 arranged axially and the second deformation part 22 arranged circumferentially, the suction bowl 2 can realize more complex elastic deformation under the action of negative pressure, which is conducive to better simulating the rhythm and intensity when the baby sucks, thereby more effectively adjusting the suction size to meet the use needs of different users.

[0068] Further, the synergistic effect of the first deformation part 21 and the second deformation part 22 can produce a more uniform and comprehensive massage effect, the first deformation part 21 can better fit the shape of the breast, and the second deformation part 22 can massage and stimulate the breast tissue in multiple directions, which helps to promote milk secretion and reduce the discomfort of the breast.

[0069] Optionally, the first deformation part 21 is in a strip shape along the axial direction of the milk suction channel 13, and the strip-shaped first deformation part 21 can deform along the axial direction of the milk suction channel 13 under the action of negative pressure, thereby ensuring that the entire milk suction channel 13 can be uniformly affected by negative pressure; the second deformation part 22 is in a ring shape along the circumferential direction of the milk suction channel 13, which is conducive to providing uniform support and pressure around the entire breast, ensuring that the breast is fully wrapped and comfortably supported during the breast pump process.​​

[0070] Furthermore, such as Figures 1 to 9 The first deformation portion 21 shown includes a plurality of spaced deformation protrusions 211 and deformation grooves 212 located between adjacent deformation protrusions 211.

[0071] Furthermore, the deformation protrusions 211 are designed to provide multiple elastic support points in the axial direction of the suction bowl 2. When negative pressure is applied, the deformation protrusions 211 can provide more flexible elastic deformation, so that the suction bowl 2 can better adapt to different breast shapes and sizes. The presence of the deformation grooves 212 increases the elastic deformation range of the suction bowl 2, so that the suction bowl 2 can deform more evenly under negative pressure, thereby better simulating the rhythm and force of infant sucking.

[0072] Furthermore, the design of the deformation protrusion 211 and the deformation groove 212 can disperse the stress under negative pressure, which helps to reduce the risk of deformation or damage to the suction bowl 2 due to excessive local stress during use, making the suction bowl 2 more stable during long-term use and extending the service life of the components.

[0073] The implementation method of Example 2 is as follows:

[0074] The difference between Example 2 and Example 1 is that: the first deformation part 21 is corrugated or wave-shaped along the axial direction of the milk suction channel 13. Each wave-shaped first deformation part 21 can produce undulating deformation under negative pressure, thereby simulating the manual massage technique and performing a deep massage on the breast tissue; the second deformation part 22 is also wave-shaped, but it is arranged around the circumference of the milk suction channel 13 to form a continuous wave-shaped structure, which is conducive to applying massage force evenly in the circumferential direction and providing comprehensive breast support and stimulation.

[0075] The implementation method of Example 3 is as follows:

[0076] The difference between Example 3 and Example 1 is that both the suction bowl 2 and the milk suction channel 13 are made of rubber. Rubber has good elasticity and can fit tightly against the smooth surface to form a stronger vacuum seal, thereby providing stronger suction. This allows the milk suction channel 13 to be more stably attached to the breast during use, reducing the possibility of air leakage.

[0077] 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.
