[0032] Example 1:

[0033] Please see Figures 1 to 10 The present invention discloses a breast pump assembly, comprising a housing 1 and a breast pumping part 2. The housing 1 has an inner cavity 11 and a housing opening 15, and further includes a contact part 3 connected to the breast pumping part 2. The contact part 3 is made of soft rubber. The breast pumping part 2 and the contact part 3 are integrally formed. The breast pumping part 2 is also provided with a limiting end 21, which is used to connect with the housing 1 to fix the relative position of the breast pumping part 2 and the housing 1. The contact part 3 is sealed to the housing 1 through the housing opening 15.

[0034] This invention integrates the milk-suction part 2 with the contact part 3 made of soft rubber material, which not only improves the connection strength and sealing of the milk-suction part 2 and the contact part 3, effectively avoiding the loosening or detachment of the contact part 3 due to prolonged use in traditional designs, but also ensures the stability and efficiency of the milk-suction process. It also enhances the comfort and suction effect of the part in contact with the breast. In addition, this one-piece molding design eliminates the connection gap between the milk-suction part 2 and the contact part 3, effectively reducing the risk of milk residue and bacterial growth, thereby reducing the possibility of user infection and improving the hygiene and safety performance of the product.

[0035] Specifically, this invention improves the stability and sealing performance of the overall component by making the milk-suction part 2 and the contact part 3, which is made of soft rubber material, a single molded structure. This integrated design not only avoids the problem of loosening or falling off of connecting parts commonly found in traditional breast pumps after prolonged use, ensuring that users can continuously obtain stable suction during use and improving milk expression efficiency, but also makes the connection between the milk-suction part 2 and the contact part 3 tighter, eliminating any possible gaps, reducing the possibility of milk residue, and thus reducing the risk of bacterial growth, providing users with a more hygienic and safer experience. Furthermore, the contact part 3 is made of soft rubber material, which not only enhances the fit between the contact part 3 and the breast, providing a more comfortable user experience, but also creates a good seal between the contact part 3 and the breast, thereby ensuring milk expression efficiency. Furthermore, by setting a limiting end 21 on the milk expression part 2 and connecting the limiting end 21 to the housing 1 and the contact part 3 respectively, the relative positions of the milk expression part 2 and the housing 1 can be further fixed, preventing relative movement between the two during use, thereby ensuring the seal during milk expression. At the same time, the relative positions of the milk expression part 2 and the contact part 3 are fixed, enhancing the overall structural strength of the milk expression part 2 and the contact part 3 after being integrally molded.

[0036] Furthermore, such as Figure 1-10 The illustration shows a breast pump assembly, wherein the breast pumping part 2 is located on the side near the breast and is arranged in a trumpet shape, and the outer side of the breast pumping part 2 is also provided with a mating end 22, and the contact part 3 is provided with a mating groove 31 for the mating end 22 to extend into.

[0037] This invention improves comfort and milk expression efficiency by arranging the milk suction part 2 in a funnel shape near the breast, making the side of the milk suction part 2 that fits the breast more closely. Furthermore, the milk suction part 2 has a mating end 22 on its outer side, and the contact part 3 has a mating groove 31 into which the mating end 22 extends. The mating end 22 and the mating groove 31 enhance the connection strength between the two, making the milk suction part 2 and the contact part 3 more secure after being integrally formed. This reduces the risk of the contact part 3 loosening or falling off, ensuring stability and sealing during the milk expression process.

[0038] Furthermore, such as Figure 1-10 The illustrated milk pump assembly has a positioning end 23 on the outer side of the milk pumping part 2. The positioning end 23 abuts against the contact part 3 to restrict the contact part 3 from moving towards the milk pumping part 2.

[0039] In this invention, a positioning end 23 is provided on the outer side of the milk suction part 2. The positioning end 23 abuts against the contact part 3 to restrict the contact part 3 from moving towards the milk suction part 2. This setting effectively prevents the contact part 3 from moving towards the milk suction part 2 due to breast compression, and avoids the deformation problem that may occur due to pressure under long-term use, thereby ensuring the overall tightness and stability of the milk suction assembly.

[0040] Furthermore, such as Figure 1-10 The illustration shows a breast pump assembly in which the depth H1 of the mating groove 31 is between one-third and two-thirds of the length H2 of one side of the contact portion 3.

[0041] This invention sets the depth H1 of the mating groove 31 to between one-third and two-thirds of the single-side length H2 of the contact part 3. This setting not only ensures the connection strength between the milk-suction part 2 and the contact part 3, but also effectively maintains the elasticity of the contact part 3. Furthermore, if the depth of the mating groove 31 is less than one-third of the single-side length of the contact part 3, there will be a lack of an effective connection support point between the milk-suction part 2 and the contact part 3, resulting in insecure fixing and possible loosening or separation during use, affecting milk-suction efficiency and sealing, and potentially leading to air leakage or reduced suction. Furthermore, if the depth of the mating groove 31 is greater than two-thirds of the single-side length of the contact part 3, although it can further enhance the connection strength, it will limit the elastic deformation ability of the contact part 3 itself, which is made of soft rubber material, reducing the adaptability of the contact part 3 to changes in breast shape, thereby reducing user comfort.

[0042] Furthermore, such as Figure 1-10 The illustrated milk pump assembly includes a contact portion 3 further comprising a limiting hole 32 for insertion of the limiting end 21.

[0043] This invention, by providing a limiting hole 32 on the contact part 3 for the insertion of the limiting end 21, makes the integral molding of the milk suction part 2 and the contact part 3 more robust and the positioning more accurate. When the milk suction part 2 and the contact part 3 are manufactured separately and then integrally molded together, the limiting end 21 and the limiting hole 32 can provide a precise positioning function, ensuring that the milk suction part 2 and the contact part 3 can be accurately aligned during the integral molding process. At the same time, it also enhances the structural strength and sealing of the milk suction part 2 and the contact part 3, ensuring the reliability and stability of long-term use. Furthermore, when the milk suction part 2 and the contact part 3 are directly manufactured through an integral molding process, this setting can also improve the connection strength between the milk suction part 2 and the contact part 3, reducing the possibility of loosening or separation during use, thereby ensuring the stability and sealing of the structure.

[0044] Furthermore, such as Figure 1-10The illustrated milk pump assembly has a protruding pressing end 33 and an abutting end 34 on the side of the contact portion 3 away from the milk pump portion 2. The inner cavity 11 of the housing is provided with a pressing surface 12 on the side of the housing opening 15. The housing 1 abuts against the abutting end 34, and the pressing end 33 cooperates with the pressing surface 12 to achieve a seal between the housing 1 and the contact portion 3.

[0045] This invention features a protruding pressing end 33 and an abutting end 34 on the side of the contact portion 3 away from the milk-suction portion 2, and a pressing surface 12 on the side of the inner cavity 11 of the housing located at the opening 15 of the housing. The housing 1 and the abutting end 34 elastically abut against each other, while the pressing end 33 and the pressing surface 12 elastically abut against each other, thus forming a double sealing effect at the connection between the housing 1 and the contact portion 3. This design not only enhances the tightness of the connection between the housing 1 and the contact portion 3, ensuring the airtight performance of the entire milk-suction assembly and avoiding air leakage caused by poor connection, but also improves the milk-suction efficiency.

[0046] Furthermore, such as Figure 1-10 The illustrated milk pump assembly has a protruding fixed end 13 located on one side of the housing opening 15 in the inner cavity 11 of the housing. The contact portion 3 is also provided with a fixing groove 35 formed by the pressing end 33 and the abutting end 34. The fixed end 13 cooperates with the fixing groove 35 so that the housing 1 is connected to the contact portion 3.

[0047] This invention features a protruding fixing end 13 on one side of the housing opening 15 within the inner cavity 11 of the housing. The pressing end 33 and the abutting end 34 on the contact portion 3 form a fixing groove 35. The engaging connection between the fixing end 13 and the fixing groove 35 securely connects the housing 1 and the contact portion 3. This design not only strengthens the connection between the housing 1 and the contact portion 3, preventing loosening or detachment during use, but also enhances the overall structural stability and sealing through the tight fit between the fixing end 13 and the fixing groove 35. Furthermore, the elastic engaging connection between the fixing end 13 and the fixing groove 35 simplifies the assembly and disassembly of the breast pump assembly, making it easy for users to assemble and disassemble, and facilitating daily cleaning and maintenance.

[0048] Furthermore, such as Figure 1-10 The illustration shows a milk suction assembly, wherein the housing 1 is further provided with a milk pouring port 14 communicating with the inner cavity 11 of the housing, the milk pouring port 14 is for the limiting end 21 to extend into, so as to fix the relative position of the milk suction part 2 and the housing 1.

[0049] This invention features a milk inlet 14 on the housing 1, communicating with the inner cavity 11 of the housing. This inlet 14 allows a limiting end 21 to extend into it, thus fixing the relative position of the milk-suction part 2 and the housing 1. This design not only provides an additional fixing point between the milk-suction part 2 and the housing 1, enhancing the connection strength, but also effectively prevents relative rotation between the milk-suction part 2 and the housing 1 through the cooperation of the limiting end 21 and the milk inlet 14, thereby ensuring stability and consistency during milk suction. Furthermore, the milk inlet 14 allows users to easily pour the breast milk collected in the inner cavity 11 of the housing into a storage container, simplifying the operation process and improving ease of use.

[0050] Furthermore, such as Figure 1-10 The illustrated milk-pumping assembly includes a contact portion 3 further comprising a disassembly portion 36 for separation from the housing 1. The contact portion 3 is made of TPE material, and the milk-pumping portion 2 is made of PP material.

[0051] In this invention, the contact part 3 is also provided with a disassembly part 36 for separation from the housing 1, which allows the user to easily separate the integrally formed structure of the milk pumping part 2 and the contact part 3 from the housing 1, facilitating the cleaning and sterilization of the milk pumping assembly; furthermore, the contact part 3 is made of TPE material, which has good softness and elasticity, which can not only better conform to the breast and improve the comfort during the milk pumping process, but also improve the sealing at the connection with the housing 1; furthermore, the milk pumping part 2 is made of PP material, which has high rigidity and heat resistance, which can ensure the structural strength and durability of the milk pumping part 2.

[0052] This embodiment proposes a milk suction assembly, which mainly consists of a housing 1, a milk suction part 2, and a contact part 3. The milk suction part 2 and the contact part 3 are manufactured by integral molding technology to enhance the connection strength.

[0053] In this embodiment, during the integral molding process of the milk-suction part 2 and the contact part 3, a mating end 22 is provided on the outer side of the milk-suction part 2, and a corresponding mating groove 31 is provided inside the contact part 3. The mating end 22 extends into the mating groove 31 and mates with it, and the depth H1 of the mating groove 31 is half the length H2 of one side of the contact part 3. This not only enhances the connection strength between the milk-suction part 2 and the contact part 3, but also maintains the softness and elasticity of the contact part 3. In addition, a positioning end 23 is provided on the outer side of the milk-suction part 2. The positioning end 23 abuts against the contact part 3, restricting the movement of the contact part 3 towards the milk-suction part 2, thus ensuring the stability of the connection between the two parts. Furthermore, a limiting end 21 is provided on the milk-suction part 2, which matches the limiting hole 32 on the contact part 3, further ensuring the stability of the connection between the two parts and helping to improve the connection strength and sealing between the milk-suction part 2 and the contact part 3.

[0054] During the installation of the pre-molded milk suction unit 2 and contact unit 3 assembly into the housing 1, it is first necessary to ensure that the limiting end 21 on the milk suction unit 2 is aligned with the milk pouring port 14 inside the housing 1. Next, the limiting end 21 is inserted into the milk pouring port 14, and the contact unit 3 is then engaged with the housing cavity 11 through the housing opening 15. At this point, the limiting end 21 is fully inserted into the milk pouring port 14 and fixes the position of the milk suction unit 2 relative to the housing 1. Simultaneously, the pressing end 33 on the contact unit 3 is tightly fitted with the pressing surface 12 of the housing cavity 11, forming a first layer of seal. Furthermore, the abutting end 34 on the contact unit 3 abuts against the side of the housing 1 located at the housing opening 15, forming a second layer of seal. The protruding fixing end 13 provided on one side of the housing cavity 11 fits precisely into the fixing groove 35 formed by the pressing end 33 and the abutting end 34 on the contact unit 3. This design not only enhances the connection strength between the housing 1 and the contact unit 3 but also facilitates easy disassembly for subsequent cleaning and maintenance.

[0055] Furthermore, to make the breast pump 2 conform more closely to the breast's curve, the side of the breast pump 2 closest to the breast is designed in a trumpet shape, and the contact part 3 is made of soft and highly elastic TPE material, greatly improving the comfort of the breast pump assembly in contact with the breast. Meanwhile, to ensure the structural strength and durability of the breast pump 2, it is made of PP material, which has good rigidity and heat resistance. Additionally, to facilitate the disassembly of the breast pump assembly 2 and the contact part 3, the contact part 3 is also provided with a disassembly part 36 for easy separation from the housing 1.

[0056] Example 2:

[0057] Please see Figure 1-10 This embodiment is similar to Embodiment 1, except that in this embodiment, the depth H1 of the mating groove 31 is two-thirds of the length H2 of one side of the contact portion 3.

[0058] Example 3:

[0059] Please see Figure 1-10 This embodiment is similar to Embodiment 1, except that in this embodiment, the depth H1 of the mating groove 31 is one-third of the single-sided length H2 of the contact portion 3.

[0060] Example 4:

[0061] Please see Figure 1-11 The present invention also proposes a breast pump, which further includes a drive assembly 4 connected to the housing 1.

[0062] This invention integrates the milk-suction part 2 with the contact part 3 made of soft rubber material, which not only improves the connection strength and sealing of the milk-suction part 2 and the contact part 3, effectively preventing the contact part 3 from loosening or falling off due to prolonged use in traditional designs, thus ensuring the stability and efficiency of the milk-suction process, but also enhances the comfort of the contact part 3 in contact with the breast and the suction effect of the milk-suction component. Furthermore, this one-piece molding design eliminates the connection gap between the milk-suction part 2 and the contact part 3, effectively reducing milk residue and bacterial growth during milk suction. The risk of gaps between part 2 and contact part 3; furthermore, the present invention also includes a drive assembly 4 connected to the housing 1, which mainly provides the necessary suction for the breast pump. In addition, the breast pump 2 is provided with a breast pumping channel communicating with the drive assembly 4 and a milk delivery channel communicating with the inner cavity 11 of the housing. This arrangement allows the suction provided by the drive assembly 4 to be transmitted to the breast pump 2 through the breast pumping channel, and then act on the breast to effectively extract milk. At the same time, the milk delivery channel ensures that the collected milk can flow smoothly into the inner cavity 11 of the housing for subsequent storage or direct use.

[0063] Furthermore, such as Figure 1-11 The breast pump shown has a placement end 16 on the side of the housing 1 away from the milk inlet 14.

[0064] This invention provides a convenient way for users to place the breast pump after it has been used to express milk. After expressing milk, users usually need to process and store the milk immediately. By providing the placement end 16, users can conveniently place the breast pump on the table while processing the milk, preventing the milk from leaking out of the pouring port 14 due to the breast pump tipping over. This design not only improves the ease of use of the breast pump but also enhances its safety during use.

[0065] 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.
