[0026] Example 1:

[0027] Please see Figure 1-5 The present invention proposes a breast pump connection structure, including a milk bowl 2 and a main unit 1 detachably connected to the milk bowl 2. The main unit 1 and the milk bowl 2 are connected by fitting along a predetermined assembly direction. The milk bowl 2 is provided with a protruding first guide end 26, and the main unit 1 is provided with a first guide groove 15 that fits with the first guide end 26. Symmetrical inclined guide edges 261 are provided on both sides of the first guide end 26 so that the main unit 1 fits with the milk bowl 2 along the predetermined assembly direction.

[0028] This invention simplifies the installation process between the main unit 1 and the milk bowl 2 by providing a protruding first guide end 26 on the milk bowl 2 and a first guide groove 15 on the main unit 1 that cooperates with the first guide end 26, and providing symmetrical inclined guide edges 261 on both sides of the first guide end 26. This allows the first guide end 26 and the inclined guide edges 261 to guide the main unit 1 to cooperate with the milk bowl 2 along a predetermined assembly direction when the user assembles the main unit 1 and the milk bowl 2.

[0029] Furthermore, compared to traditional breast pumps where users can only rely on visual alignment or intuition to connect the main unit 1 and the milk bowl 2, often requiring multiple attempts to find the correct installation position in low-light environments, this invention, through the design of the first guide end 26 and the first guide groove 15, allows the user to naturally guide the main unit 1 along a predetermined path to accurately slide into the correct docking position with the milk bowl 2, even at night or in poor lighting conditions, without the need for repeated adjustments of the viewing angle or multiple attempts, thus improving the convenience and efficiency of user operation. Furthermore, by providing symmetrical inclined guide edges 261 on both sides of the first guide end 26, it not only further guides the main unit 1 accurately into the first guide groove 15, but also, due to the inclined guide edges 261... The tilt angle of the inclined guide edge 261 provides a gradually tightening guide path during the engagement of the main unit 1 and the milk bowl 2, allowing the main unit 1 to connect with the milk bowl 2 more smoothly and naturally, reducing the need for repeated adjustments due to inaccurate alignment, and effectively reducing the resistance encountered by the user during installation. Furthermore, the inclined guide edge 261 can also compensate for small errors that may occur during manufacturing and assembly. If there is a slight deviation in the manufacturing precision of the main unit 1 or the milk bowl 2, or if the user fails to align them completely during installation, the inclined guide edge 261 can play a corrective role, ensuring that the main unit 1 can still be successfully connected to the milk bowl 2. In some embodiments, the inclined guide edge 261 is arc-shaped, further enhancing the guiding effect and making it easier for the main unit 1 to be installed in the correct position.

[0030] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the shape of the first guide groove 15 is adapted to the shape of the first guide end 26, and the cross-section of the first guide end 26 is approximately triangular or approximately trapezoidal.

[0031] This invention sets the cross-section of the first guide end 26 to an approximately triangular shape, enabling the main unit 1 to more accurately reach the correct position along the predetermined assembly direction when docking with the milk bowl 2. This setting allows the first guide end 26 to provide a clear guiding point for the initial contact between the first guide groove 15 and the first guide end 26, ensuring that the connection between the main unit and the milk bowl can be successfully achieved even in low light conditions. Furthermore, in some other embodiments, the cross-section of the first guide end 26 is approximately trapezoidal. This setting not only retains the advantages of a triangle but also increases the width of the guide path, thereby further improving the stability and fault tolerance during the installation process.

[0032] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the milk bowl 2 is provided with a first side wall 22 arranged along a predetermined assembly direction of the main unit 1, and a mating groove 211 located on the opposite side of the first side wall 22. The main unit 1 is also provided with a second side wall 13 that mates with the first side wall 22, and a first mating part 11 that mates with and connects to the mating groove 211. The first guide end 26 is provided on the first side wall 22, and the first guide groove 15 is provided on the second side wall 13.

[0033] This invention simplifies the alignment process between the main unit 1 and the milk bowl 2 by providing a mating groove 211 on the milk bowl 2 and a corresponding first mating part 11 on the main unit 1, which engages with the first guide end 26 on the first side wall 22 and the first guide groove 15 on the second side wall 13. This allows the user to simply push the main unit 1 along the predetermined assembly direction to insert the first mating part 11 into the mating groove 211, thereby completing the installation with the milk bowl 2 and improving the ease of operation. Furthermore, this design not only simplifies the overall assembly steps but also enhances the firmness of the connection between the main unit 1 and the milk bowl 2.

[0034] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the second sidewall 13 is further provided with an elastic abutment end 12. There are at least two elastic abutment ends 12, which are symmetrically arranged on both sides of the second sidewall 13. The elastic abutment ends 12 elastically abut against the first sidewall 22 to drive the first mating part 11 to abut against and fix the mating groove 211.

[0035] In this invention, the elastic abutment end 12 is elastically abutted against the first side wall 22. The elastic force provided by the elastic abutment end 12 ensures that the first mating part 11 can tightly fit the mating groove 211, and the friction between the two achieves a stable fixing effect between the main unit 1 and the milk bowl 2. This arrangement not only effectively ensures a tight connection between the main unit 1 and the milk bowl 2, but also makes the installation process smoother and simpler. Furthermore, at least two elastic abutment ends 12 are provided, and when these two elastic abutment ends 12 are symmetrically arranged on both sides of the second side wall 13, the elastic abutment ends 12 can distribute pressure more evenly, ensuring a more stable and smooth connection between the main unit 1 and the milk bowl 2. This also reduces the force required by the user during installation, greatly improving the user experience. Furthermore, the symmetrical arrangement of the elastic abutment ends 12 also allows for more even force when the user assembles the main unit 1 and the milk bowl 2, ensuring a smoother installation each time. Furthermore, in this embodiment, two elastic abutment ends 12 are provided.

[0036] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the first sidewall 22 is further provided with an abutment groove 221 that mates with the elastic abutment end 12, and the abutment groove 221 has an arc-shaped cross-section.

[0037] This invention provides an abutment groove 221 on the first side wall 22 that mates with the elastic abutment end 12. When the main unit 1 and the milk bowl 2 are properly engaged, the elastic abutment end 12 can accurately enter the abutment groove 221. This not only provides a tactile indication to the user that the parts are in place, but also effectively prevents the elastic abutment end 12 from accidentally shifting due to external force. This ensures that the engagement of the main unit 1 and the milk bowl is easier and improves the stability and reliability of the connection. In addition, the abutment groove 221 is designed with an arc shape, which allows the elastic abutment end 12 to transition more smoothly when entering or leaving the abutment groove 221, reducing frictional resistance.

[0038] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the milk bowl 2 is further provided with a first cover plate 23 that is angled to a first side wall 22. The first side wall 22 and the first cover plate 23 form an installation area 24 for installing the main unit 1. The main unit 1 is further provided with a second cover plate 14 that cooperates with the first cover plate 23. The second cover plate 14 is provided with a second guide end 141 extending toward the first cover plate 23 on the side away from the first side wall 22. The milk bowl 2 is further provided with a second guide groove 25 into which the second guide end 141 extends.

[0039] This invention provides a first sidewall 22 and a first cover plate 23 connected at an angle to the first sidewall 22 in the milk bowl. The first sidewall 22 and the first cover plate 23 form an installation area that can support and install the main unit 1, allowing the main unit 1 to be stably placed on the milk bowl 2. Furthermore, by providing a second guide end 141 extending toward the first cover plate 23 on the side of the second cover plate 14 away from the first sidewall 22, and by providing a second guide groove 25 for the second guide end 141 to extend into, this design further ensures the alignment process between the main unit 1 and the milk bowl 2. This allows the user to complete the installation of the main unit 1 and the milk bowl 2 simply by pushing them in a predetermined direction, without the need for additional angle adjustments or repeated attempts.

[0040] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the second guide groove 25 is provided with a limiting part 251 for limiting the insertion depth of the second guide end 141, the mating groove 211 is provided on the limiting part 251, and the first mating part 11 is provided on the second guide end 141.

[0041] This invention, by providing a limiting part 251 within the second guide groove 25 to restrict the insertion depth of the second guide end 141, can control the connection depth between the main unit 1 and the milk bowl 2, thereby ensuring consistency and stability in each installation and avoiding the risk of component damage due to over-insertion. Furthermore, by placing the mating groove 211 on the limiting part 251 and the first mating part 11 on the second guide end 141, the user can complete the mating of the first mating part 11 and the mating groove 211 simply by relying on the guiding effect of the second guide end 141 and the second guide groove 25, thereby further improving the smoothness and accuracy of the installation process of the main unit 1 and the milk bowl 2.

[0042] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the connection between the first sidewall 22 and the first cover plate 23 is provided with an arc-shaped arched portion 27, and the connection between the second sidewall 13 and the second cover plate 14 is provided with a positioning groove 16 for fitting with the arched portion 27.

[0043] This invention features an arc-shaped arched portion 27 at the connection between the first side wall 22 and the first cover plate 23, and a positioning groove 16 at the connection between the second side wall 13 and the second cover plate 14, which is adapted to the shape of the arched portion 27 and fits snugly against it. This arrangement helps to position the main unit 1 and the milk bowl 2 relative to each other, preventing the main unit 1 from moving left or right relative to the milk bowl 2, thus making the fixation of the main unit 1 and the milk bowl 2 more stable. Furthermore, the tight fit between the arched portion 27 and the positioning groove 16 also helps to enhance the stability of the connection between the main unit 1 and the milk bowl 2. In addition, this arrangement not only increases the structural stability between the main unit 1 and the milk bowl 2, but also simplifies the alignment process. When the user performs the installation operation, the arched portion 27 can be naturally guided into the positioning groove 16, ensuring the precise docking between the main unit 1 and the milk bowl 2, and strengthening the connection strength between the main unit 1 and the milk bowl 2.

[0044] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the first cover plate 23 is provided with a negative pressure connector 231, and the second cover plate 14 is also provided with a negative pressure inlet 18 connected to the negative pressure connector 231. The negative pressure inlet 18 includes a flexible part, and the negative pressure connector 231 and the flexible part of the negative pressure inlet 18 are connected by an interference fit.

[0045] This invention provides a negative pressure connector 231 on the first cover plate 23 and a flexible negative pressure inlet 18 on the second cover plate 14. The interference fit between the negative pressure connector 231 and the flexible portion of the negative pressure inlet 18 achieves a tight, leak-free connection, improving the breast pump's pumping effect and simplifying assembly, allowing users to install the device more easily. Furthermore, this design ensures that the connection between the main unit 1 and the milk bowl 2 will not easily loosen even during slight vibration or movement, further enhancing the connection stability between them. In this embodiment, the negative pressure inlet 18 is made of silicone material.

[0046] Furthermore, such as Figure 1-5 The diagram shows a breast pump connection structure, wherein the main unit 1 is further provided with detachable ends 17 located on both sides adjacent to the second side wall 13.

[0047] This utility model provides detachment ends 17 on the second sidewall 13 of the main unit 1 on both sides, with the detachment ends 17 protruding from the surface of the main unit 1. This arrangement allows the user to easily apply external force to release the connection between the elastic abutment end 12 and the second mating part 21 through the detachment ends 17, thereby easily separating the main unit 1 from the milk bowl 2 and effectively simplifying the user's operation process when separating the main unit 1 from the milk bowl 2.

[0048] Example 2:

[0049] Furthermore, such as Figure 1-5 The breast pump shown includes a breast pump connection structure and a bra 3 connected to the milk bowl 2.

[0050] This invention improves user comfort by providing a bra 3 connected to the milk bowl 2, with the bra 3 being the part that directly contacts the breast. Furthermore, by applying the breast pump connection structure to the breast pump, users can more quickly and accurately assemble the main unit 1 and the milk bowl 2 even at night or in poor lighting conditions, thereby reducing the difficulty of alignment during installation. Moreover, this design ensures a tight fit between the main unit 1 and the milk bowl 2, improving the stability and reliability of the equipment.
