[0036] Embodiment 1:

[0037] As shown in the figure, the roller operating device for breast pump of the embodiment comprises a support 1, a roller support 2 with a first roller hole 21 at the top is arranged on the support 1, a roller structure is rotatably connected on the roller support 2, a PCBA module 5 is further arranged on the support 1, an encoder 51 is arranged on one side of the roller support 2 on the PCBA module 5, the encoder 51 can detect the rotation of the roller structure to send a signal to control the breast pump. Figures 1 to 6

[0038] Specifically, the encoder on the PCBA module can accurately detect the rotation of the roller structure to realize the blind operation of the breast pump.

[0039] The user can feel the force and feedback of gear adjustment through the rotation of the roller. Physical feedback allows the user to clearly perceive the operation result without visual confirmation, avoiding the occurrence of misoperation. This tactile feedback improves the intuitiveness and safety of use, so that the user can accurately operate the breast pump even in low light environment or distracted state.

[0040] This design maximizes the use of keys, reduces the complex key layout of traditional breast pumps, and users can easily adjust the gear size of the breast pump without needing to focus on the buttons. In addition, users can still operate conveniently when performing other activities, such as holding a child or performing daily activities, which not only reduces hardware costs and production complexity, but also makes the operation interface more simple and clear. Especially for novice mothers, the simplified operation process significantly improves the convenience of use, reduces confusion and learning cost.

[0041] Preferably, the encoder 51 can adopt a mechanical encoder or an optical encoder, and the appropriate design can be selected according to actual needs.

[0042] As shown in the figure, the roller operating device for breast pump of the embodiment comprises a support 1, a roller support 2 with a first roller hole 21 at the top is arranged on the support 1, a roller structure is rotatably connected on the roller support 2, a PCBA module 5 is further arranged on the support 1, an encoder 51 is arranged on one side of the roller support 2 on the PCBA module 5, the encoder 51 can detect the rotation of the roller structure to send a signal to control the breast pump. Figures 1 to 6 ​As shown, the roller structure of this embodiment includes a roller 3 and a rotating shaft assembly 4 disposed on the roller 3. The side wall of the roller bracket 2 is provided with a shaft hole for the end of the rotating shaft assembly 4 to pass through the roller bracket 2. The encoder 51 is provided with a first mounting hole 511 for one end of the rotating shaft assembly 4 to pass through. The encoder 51 in this embodiment is a mechanical encoder. By cooperating with the end of the rotating shaft assembly 4, the encoder can accurately detect the rotation of the roller. It has the advantages of simple structure, low cost and high reliability.

[0043] like Figures 1 to 6 As shown, the PCBA module 5 in this embodiment is also provided with a function button 52 located on one side of the roller bracket 2. The roller structure includes a roller 3 and a rotating shaft assembly 4 disposed on the roller 3. The side wall of the roller bracket 2 is provided with a shaft hole for the end of the rotating shaft assembly 4 to pass through the roller bracket 2. The function button 52 is located below the end of the rotating shaft assembly 4. When the roller 3 is pressed, the rotating shaft assembly 4 can press the function button 52.

[0044] Preferably, a function button 52 is added to the PCBA module 5 so that the encoder and the function button can work together with the roller shaft assembly 4. The encoder can accurately detect the rotation of the roller, and the function button realizes the switching on and off and mode switching functions of the breast pump through the movement of the shaft assembly 4.

[0045] The encoder ensures the accuracy of gear adjustment and can make precise adjustments according to the angle of rotation, while the push-button function ensures the reliability and sensitivity of mode switching and power control, thereby enhancing the response speed and stability of the entire device.

[0046] Furthermore, both the rotation and pressing of the rollers provide physical feedback. Users can feel the force and feedback of the gear adjustment through the rotation of the rollers, and the "pressing" sensation when pressing provides clear confirmation of the operation. Physical feedback allows users to clearly perceive the operation result without visual confirmation, avoiding misoperation. This tactile feedback improves the intuitiveness and safety of use, enabling users to accurately operate the breast pump even in low-light environments or when distracted.

[0047] This design minimizes the use of buttons and reduces the complex button layout of traditional breast pumps. Users can easily adjust the pump's intensity without having to focus on the buttons. Furthermore, users can still operate the pump conveniently while doing other activities, such as holding the baby or performing daily tasks. This not only reduces hardware costs and manufacturing complexity but also makes the user interface simpler and clearer. Especially for new mothers, the simplified operation process significantly improves ease of use and reduces confusion and learning costs.

[0048] Specifically, the device uses the rotation of the roller to complete gear adjustment, mode switching and power-on / off operation, especially the pressing function of the roller, which realizes mode switching and power-on / off by pressing the roller, thereby further reducing the number of keys on the traditional breast pump. By adopting the roller structure and simplified mechanical operation mode, the user can adjust the gear of the breast pump by rotating the roller (forward or reverse), without having to look down to check or identify complex keys and icons. The use of the roller is very ergonomic and intuitive to operate, and the user can not have to concentrate on finding the button position.

[0049] As shown in Figures 1 to 6 The shaft hole of the embodiment includes a first shaft hole 22 and a second shaft hole 23 arranged on both sides of the roller support 2.

The encoder 51 is provided with a first assembly hole 511 for the roller support shaft 41 to pass through, and the function key 52 is located below the pressing shaft 42.

[0050] With such a design, the space on both sides of the roller support 2 can be fully utilized to make the structure of the roller operation device more compact. Moreover, the roller support shaft 41 and the pressing shaft 42 on both sides of the roller support 2 correspondingly control the encoder 51 and the function key 52, which reduces the possibility of user misoperation and further improves the user experience.

[0051] As shown in Figures 1 to 6 The roller support 2 of the embodiment includes an upper support 24 and a lower support 25. The lower support 25 is arranged on the support base 1, and the upper support 24 is detachably connected to the lower support 25.

[0052] Specifically, the separate design of the upper support 24 and the lower support 25 makes the assembly and disassembly of the roller support 2 more flexible. The lower support 25 is fixed on the support base 1 to serve as a support and fixing function. The upper support 24 and the lower support 25 are detachably connected, which allows the roller 3 and the shaft assembly 4 to be easily assembled and disassembled on the roller support 2 without disassembling the entire roller support 2. This design can be applied to both rigid and flexible structures of the roller support 2, and the appropriate design can be selected according to actual needs.

[0053] Preferably, in other embodiments, the detachable connection between the upper support 24 and the lower support 25 can be achieved by simple buckles, screws, slots, etc. This connection method allows the entire device to be disassembled when replacement or maintenance is needed, and only the upper support or the lower support needs to be replaced, which is convenient for maintenance.

[0054] Preferably, the detachable connection structure of the upper support and the lower support simplifies the installation process of the roller 3 and the rotating shaft assembly 4, reduces the assembly time, and improves the production efficiency.

[0055] Further, when the roller structure needs to be replaced or repaired, the upper support 24 can be disassembled, and the operator does not need to disassemble the entire device, which improves the convenience of maintenance and saves time.

[0056] As shown in the drawings, the upper support 24 of the embodiment is provided with a connecting assembly capable of detachably connecting the upper support 24 and the support 1. Figures 1 to 6

[0057] Specifically, the main function of the connecting assembly is to form a detachable connection between the upper support 24 and the support 1. Through this detachable connection mode, the user can conveniently separate or reconnect the upper support 24 and the support 1. The connecting assembly includes but is not limited to buckle connection, latch connection, screw / bolt connection, etc., which can ensure that the two are stably connected together, and can also be easily disassembled when needed.

[0058] In the embodiment, the upper support 24 and the lower support 25 are also provided with a docking assembly, the docking assembly includes a docking protrusion 243 and a docking groove 251, when the docking protrusion 243 is inserted into the docking groove 251, the upper support 24 is assembled on the lower support 25, and the connecting assembly between the upper support 24 and the support 1 can be connected to connect the upper support 24 and the support 1, and stably assemble the upper support 24 on the lower support 25. With such a design, the connecting components between the upper support 24 and the lower support 25 can be saved, the structure of the roller support 2 is further optimized, and the assembly of the upper support 24 on the lower support 25 and the support 1 is facilitated. The docking assembly also plays a role in positioning and sealing.

[0059] Preferably, in other embodiments, the upper support 24 and the lower support 25 are provided with a connecting assembly to realize the connection between the two, and the connecting assembly is not provided between the upper support 24 and the support 1; or, the upper support 24 and the lower support 25 are provided with a connecting assembly to realize the connection between the two, and the connecting assembly is also provided between the upper support 24 and the support 1. The appropriate design can be selected according to the actual needs.

[0060] As shown in the drawings, Figures 1 to 6 ​As shown, the connecting assembly of the embodiment includes first connecting columns 241 arranged on the upper support 24 and second connecting columns 11 arranged on the support 1, the number of the first connecting columns 241 is at least two, and the plurality of first connecting columns 241 are arranged at intervals, the second connecting columns 11 are arranged one by one corresponding to the first connecting columns 241, and the connecting assembly further includes a connecting member capable of connecting the first connecting column 241 with the corresponding second connecting column 11. This stable connection design can make the assembly more convenient, and no additional tools are needed to reinforce the connection, ensuring that the user can easily complete the installation and disassembly process, while ensuring the stability of the connection at each operation.

[0061] Specifically, by arranging a plurality of first connecting columns 241 and distributing them at intervals, the uniformity and stability of the connection can be ensured, and the one-to-one correspondence design of the plurality of first connecting columns 241 and the second connecting columns 11 ensures the stability and firmness of the connection process. The plurality of connection points make the stress of the entire connection area more uniform, which can disperse the stress between the upper support 24 and the support 1, ensuring the stability of the support. Especially when the device bears a large load, multi-point connection can effectively avoid the stress concentration problem caused by single-point connection, and improve the carrying capacity of the overall structure.

[0062] Specifically, the connecting member is responsible for connecting the first connecting column 241 with the corresponding second connecting column 11, and the specific form of the connecting member can include screws, nuts, buckles, pins, spring pins, etc., which ensures stable connection and convenient disassembly when necessary. The connecting member not only ensures firm connection, but also facilitates disassembly for maintenance and adjustment.

[0063] As shown, Figures 1 to 6 As shown, the PCBA module 5 of the embodiment includes a PCB board located between the first connecting column 241 and the second connecting column 11, and the PCB board is provided with a second assembly hole 53 corresponding to the first connecting column 241, and the connecting member can pass through the corresponding second connecting column 11, the second assembly hole 53 and the first connecting column 241, so that the PCB board is arranged on the support 1.

[0064] In the embodiment, the PCB board is provided with a second assembly hole 53 corresponding to the first connecting column 241, and the second assembly hole 53 matches the first connecting column 241 and the second connecting column 11, ensuring accurate docking during connection, allowing the connecting member (such as a screw or a pin) to pass through the second connecting column 11, the second assembly hole 53 and the first connecting column 241 to form a connection, realizing the stable assembly of the PCB board and the support 1. Through this design, the connecting member can ensure that the PCB board is firmly fixed on the support 1 and will not loosen due to external impact or vibration.

[0065] With the support 1 of the embodiment as an example, the bottom of the support 1 is provided with a connecting hole communicated with the second connecting column 11. In the assembly process, the PCB is first assembled on the support 1, the upper support 24 is assembled on the lower support 25, at this time the first connecting column 241, the second assembly hole 53 and the second connecting column 11 are aligned, then the connecting member passes through the connecting hole, the second connecting column 11 and the second assembly hole 53 in sequence, and then is connected with the first connecting column 241 to fix the PCB between the first connecting column 241 and the second connecting column 11, ensuring that the PCB is stably assembled on the support 1. The design of this connection method ensures the accuracy and stability of the assembly, and also simplifies the entire assembly process and avoids complex fixing methods.

[0066] Preferably, the connecting member fixes the PCB firmly on the support 1 through multiple precise positioning points to prevent external impact or vibration from affecting the PCB. This design helps to improve the stability of the equipment, especially during long-term use, effectively reducing the displacement or loosening of the PCB.

[0067] Preferably, such design saves the parts for fixing the PCB on the support 1, and only one set of fixing structure is needed to stably assemble the PCB and the upper support 24 on the support 1 and the lower support 25, having the advantages of simple structure and convenient operation.

[0068] Preferably, in the embodiment, the connecting hole is a counterbore, and the connecting member is a screw, the head of which is hidden in the counterbore, which can make the structure of the device more compact and beautiful, and appropriate design can be selected according to actual needs.

[0069] As shown in Figures 1 to 6 The support 1 of the embodiment is also provided with multiple positioning columns 12, and the PCB is provided with multiple positioning holes 54 corresponding to the positioning columns 12. With such design, the PCB can be precisely positioned and assembled on the support 1, thereby improving the accuracy and stability of the assembly. Through multiple positioning points, the PCB can be more stably fixed on the support 1 to prevent loosening or deformation caused by uneven force or external vibration. This design can improve the stability and reliability of the equipment during use, especially in long-term use or in scenes with large environmental vibration, which can effectively maintain the firmness of the connection.

[0070] As shown in Figures 1 to 6As shown, each positioning post 12 in this embodiment has a plurality of first supporting protrusions 121 circumferentially arranged on its outer wall. When the PCB board is installed on the support 1, the top of the first supporting protrusion 121 abuts against the bottom of the PCB board, providing support for the PCB board, ensuring that the PCB board can remain stable on the support 1 without displacement, effectively distributing the weight of the PCB board, and reducing the risk of single-point pressure concentration through a uniform contact surface. Since these protrusions are circumferentially distributed, they can ensure that the entire PCB board receives stable support during installation, avoiding the problem of PCB board deformation or loosening due to insufficient support points or uneven force.

[0071] Preferably, the presence of the first supporting protrusion 121 can greatly increase the contact area of ​​the support point, enabling the PCB board to obtain more uniform support and reducing the risk of deformation or tilting. Each supporting protrusion 121 bears a portion of the weight and can support the PCB board together with the second connecting column 11, so that the PCB board always maintains a stable position, thereby enhancing the stability of the overall structure.

[0072] Preferably, in this embodiment, there are four positioning posts 12, which are located near the four corners of the PCB board, forming a stable support surface. By distributing the support force to the four corners, the weight of the entire PCB board can be evenly distributed to multiple support points, avoiding damage or instability caused by excessive force on a single support point, reducing the possibility of warping or uneven stress on the PCB board, and preventing deformation or damage.

[0073] like Figures 1 to 6 As shown, the top of the upper bracket 24 in this embodiment is provided with an outwardly extending positioning edge 242. The positioning edge 242 can be engaged with the breast pump housing 100. Through the engagement design between the positioning edge 242 and the breast pump housing 100, the assembly process becomes simpler. The assembler only needs to align the upper bracket 24 with the housing 100, and the positioning can be completed by engaging the positioning edge 242, avoiding complicated docking and fixing operations and reducing human error.

[0074] Preferably, the first connecting post 241 is located at the bottom of the positioning clip edge 242, which can optimize the structure of the roller operating device, making the structure of the device more compact. At the same time, the first connecting post 241 also enhances the structural strength of the positioning clip edge 242, making the entire connection have a higher load-bearing capacity, which can cope with the large load or impact that may occur during the use of the equipment and extend its service life.

[0075] Preferably, a portion of the outer wall of the first connecting post 241 is connected to the outer wall of the upper bracket 24, making the connection between the first connecting post 241 and the upper bracket 24 more stable.

[0076] In some other embodiments, the first connecting column 241 is connected only with the positioning card 242 or only with the outer wall of the upper support 24, and a suitable design can be selected according to actual needs.

[0077] As shown in Figures 1 to 6 The PCBA module 5 of the present embodiment is provided with an avoiding hole 56 capable of avoiding the roller support 2. In the present embodiment, the avoiding hole 56 is arranged on the PCB board, that is, the PCB board is sleeved on the outer side of the roller support 2 through the avoiding hole 56. By adopting such a design, the structure of the whole roller operating device is more compact, which is beneficial to reducing the volume of the roller operating device.
