Description

Technical Field

[0001] This application relates to the field of breast pump technology, and in particular to a control method for a breast pump assembly and a breast pump assembly. Background Technology

[0002] Currently, breast pumps can synchronize operational data (such as pumping time, milk volume, and mode) to a mobile app via Bluetooth for convenient viewing and management. However, existing charging cases are only used for collecting milk and charging the breast pump. The charging process is controlled independently internally, and users cannot control the charging behavior according to their own needs, nor can they obtain relevant information about the charging case (such as whether it is currently charging, charging progress, battery temperature, whether protection mechanisms have been triggered, battery health assessment, etc.). This results in users lacking understanding and control over the charging case, thus reducing the user experience. Summary of the Invention

[0003] The main purpose of this application is to propose a control method for a breast pump component and a breast pump component, which aims to enable users to control the charging behavior of the charging box and understand its relevant charging information.

[0004] To achieve the above objectives, this application proposes a control method for a breast pump assembly, the breast pump assembly including a breast pump and a charging device, characterized in that the charging device has a power output interface and a first signal transmission terminal, the breast pump has a power input interface and a second signal transmission terminal, and the breast pump assembly is configured to output a first electrical signal via the second signal transmission terminal when not confirmed to be connected to the charging device; the control method includes: The charging device is configured as follows: The connection status with the breast pump is determined based on the signal changes received by the first signal transmission terminal. When the connection with the breast pump is confirmed, a charging current is output to the breast pump through the power output interface and the power input interface to charge the breast pump. The breast pump is configured as follows: When the current detected at the power input interface is greater than a preset current threshold, a handshake process with the charging device is initiated. When the handshake process is successful, a communication link is established with the charging device, and data interaction is performed through the communication link.

[0005] In one embodiment, the handshake process for initiating the charging device includes: The breast pump is configured to send a handshake command via the second signal transmission terminal when it detects that the current received at the power input interface is greater than a preset current threshold. The charging device is configured to: upon receiving the handshake instruction via the first signal transmission terminal, determine that the handshake with the breast pump has been successful, and output a response signal to the breast pump; The breast pump is configured to determine that a handshake with the charging device has been successfully completed upon receiving a response signal.

[0006] In one embodiment, the step of determining that the handshake with the breast pump was successful and outputting a response signal to the breast pump upon receiving the handshake command via the first signal transmission terminal includes: The charging device is configured to: upon receiving the handshake command via the first signal transmission terminal, output a first current signal / first voltage signal via the power output interface; the response signal includes the first current signal / first voltage signal; Alternatively, the charging device is configured to: upon receiving the handshake instruction via the first signal transmission terminal, send a response instruction via the second signal transmission terminal; the response signal includes the response instruction. Alternatively, the charging device is configured to: upon receiving the handshake instruction via the first signal transmission terminal, output a first current signal / first voltage signal via the power output interface, and also send a response instruction via the second signal transmission terminal; the response signal includes the first current signal / first voltage signal and the response instruction.

[0007] In one embodiment, the step of outputting a first current signal / first voltage signal through the power output interface when the handshake command is received via the first signal transmission terminal includes: The charging device is configured to perform a preset number of restart operations upon receiving a handshake command, so as to output a first current signal / first voltage signal through the power output interface.

[0008] In one embodiment, the number of breast pumps is multiple, each breast pump has a unique identifier, and the charging device has multiple charging slots for accommodating the breast pumps, each charging slot having a power output interface and a first signal transmission terminal; the control method further includes: The charging device is configured to: when a breast pump is detected to be connected to any charging slot, read the identity identifier sent when the breast pump starts the handshake process, and compare the read identity identifier with the identity identifier of the target breast pump that is pre-paired with the charging slot; If the identity identifier does not meet the target conditions, a first prompt action is triggered to remind the user that the breast pump is placed incorrectly, and the output of charging current to the breast pump through the power output interface and the power input interface is stopped. If the identity identifier meets the target conditions, the first signal transmission terminal of the charging device is driven to establish a communication link with the second signal transmission terminal of the breast pump.

[0009] In one embodiment, the charging device is further configured to: Obtain the duration for which the identity identifier does not meet the target conditions, and use this duration as the first duration; When the first duration exceeds the first preset duration, a communication link is established with the breast pump, and a charging current is output to the breast pump through the power output interface and the power input interface. The data obtained from charging and data interaction with the breast pump is associated and recorded as the data of the target breast pump that is preset to be paired with the charging slot.

[0010] In one embodiment, triggering a first prompt action to notify the user of incorrect breast pump placement if the identity identifier does not meet the target conditions includes: The charging device is configured to: after triggering the first prompt action, perform a first count of events in which the identity of the breast pump does not meet the target conditions; When the value of the first count is greater than the first preset value, the position correction prompt of the breast pump is sent to the external terminal. Within the preset response time after sending the position correction prompt, when the position modification instruction returned by the external terminal is received, the identity of the breast pump is updated to the pairing target of the charging slot. And / or, after sending a location correction prompt to an external terminal, obtain the increment of the first count, and when the increment of the first count is greater than a second preset value, update the identity of the breast pump to the pairing target of the charging slot.

[0011] In one embodiment, the control method further includes: The charging device is configured to: after establishing a communication link with the breast pump, acquire the historical operating parameters of the breast pump host; Frequency statistics are performed on the historical working parameters to determine the most frequently occurring parameter combinations; The most frequently occurring parameter combination is stored as the optimal working mode parameter package of the breast pump, and the optimal working mode parameter package of the breast pump is sent to the breast pump so that the breast pump can work in the optimal working mode.

[0012] This application also proposes a breast pump assembly, including a breast pump and a charging device. The charging device has a power output interface and a first signal transmission terminal, and the breast pump has a power input interface and a second signal transmission terminal. When the charging device is connected to the breast pump, the power input interface is connected to the power output interface, and the second signal transmission terminal is connected to the first signal transmission terminal. The breast pump and the charging device are used to operate the control method of the breast pump assembly described above.

[0013] In one embodiment, the charging device includes a first battery circuit, a first control circuit, and a first switching circuit. The first battery circuit is connected to the power output interface. The first control circuit is connected to the controlled terminal of the first switching circuit and the controlled terminal of the first battery circuit. The first terminal of the first switching circuit is connected to the first signal transmission terminal. The first control circuit has a status detection interface and a first signal transmission interface. The second terminal of the first switching circuit is connected to the status detection interface. The third terminal of the first switching circuit is connected to the first signal transmission interface. The breast pump includes a second battery circuit, a second control circuit, and a second switching circuit. The second battery circuit is connected to the power input interface. The second control circuit is connected to the controlled end of the second switching circuit. The first end of the second switching circuit is connected to the second signal transmission end. The second control circuit has a second signal transmission interface. The second end of the second switching circuit is connected to the second signal transmission end. The third end of the second switching circuit is connected to a first electrical signal.

[0014] When the breast pump assembly and the charging device first connect, the breast pump assembly, before confirming its connection, actively sends a first electrical signal from its second signal transmission terminal. This causes a recognizable signal change in the charging device's first signal transmission terminal. Upon detecting this signal change, the charging device confirms the connection and sequentially outputs charging current to the breast pump via its power output and power input interfaces to charge it. When the breast pump detects that the current at its power input interface exceeds a preset current threshold, it confirms its connection and initiates a handshake process to attempt to establish a communication connection. Once the handshake is successful, a communication link is established, and data exchange occurs through this link.

[0015] This setup allows the charging device to wirelessly communicate with a mobile app during data exchange with the breast pump. Users can then send control signals to the breast pump via the app, which in turn transmits these signals to the charging device. The charging device adjusts its charging process accordingly, such as activating a slow charging mode for nighttime use or pausing charging to reduce temperature rise, thus meeting individual user needs.

[0016] On the other hand, the charging device can upload its own working status and management information (such as current battery level, real-time temperature, number of charge and discharge cycles, health assessment, charging mode, protection event records, etc.) to the breast pump, and synchronize it to the APP. This allows users to not only view the data of the breast pumping process, but also to have a comprehensive understanding of the transparent information of the charging process, thus improving the user experience.

[0017] Furthermore, during data interaction with the breast pump, the charging device can also obtain battery information such as battery level, battery health, and battery temperature. This allows the charging device to manage the charging of the breast pump's battery based on its operating parameters. For example, when the battery temperature is detected to be too high, it can automatically switch to trickle charging or pause charging to prevent overheating and damage to the battery cells. Alternatively, if the battery level is too low, it can activate fast charging mode to shorten the waiting time. Compared to existing charging devices that only provide electrical energy, this not only ensures charging safety and extends battery life but also improves charging efficiency, thereby enhancing the user experience.

[0021] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] To address the technical problem of users' lack of understanding and control over the charging box, this application proposes a control method for a breast pump assembly, which includes a breast pump and a charging device. In one embodiment, referring to... Figure 1 The charging device has a power output interface and a first signal transmission terminal, and the breast pump has a power input interface and a second signal transmission terminal; the breast pump assembly is configured to control the second signal transmission terminal to send a first electrical signal when not confirmed to be connected to the charging device; Reference Figure 2 The control method includes: Step S100: The charging device is configured as follows: The connection status with the breast pump is determined based on the signal changes received by the first signal transmission terminal. Step S200: When it is determined that the breast pump is connected to the breast pump, a charging current is output to the breast pump through the power output interface and the power input interface to charge the breast pump; Step S300: The breast pump is configured as follows: When the current detected at the power input interface is greater than a preset current threshold, a handshake process with the charging device is initiated. Step S400: When the handshake process is successful, a communication link is established with the charging device, and data interaction is performed through the communication link.

[0024] It should be noted that a breast pump is a device used to perform milk expression, and a charging device is a power supply used to charge the breast pump. The power output and input interfaces include positive and negative terminals so that when connected, the positive and negative terminals can be electrically connected to form a complete charging circuit. The charging device charges the breast pump through this charging circuit. The first and second signal transmission terminals can be implemented using metal contacts or probes.

[0025] In this embodiment, when the charging device is connected to the breast pump, the power input interface is connected to the power output interface, and the second signal transmission terminal is connected to the first signal transmission terminal. This connection ensures a stable structure when the breast pump and charging device are connected, allowing the power output interface to be stably connected to the power input interface, and the first signal transmission terminal to be stably connected to the second signal transmission terminal. For example, the charging device has a charging slot. When the breast pump is placed in the charging slot, the two devices achieve stable alignment through structural design (such as snap-fit, magnetic positioning, guide grooves, etc.), ensuring precise contact of the interface points.

[0026] In one embodiment, the first electrical signal can be implemented using a low-level signal. Specifically, when the breast pump is not confirmed to be connected to the charging device, the second signal transmission terminal can be grounded to make its first electrical signal a low-level signal. The charging device can pull up the second signal transmission terminal to make its signal level high when it is not confirmed to be connected to the breast pump. When the first signal transmission terminal is connected to the second signal transmission terminal, the second signal transmission terminal is pulled low by the first signal transmission terminal, causing the first signal level to change to a low-level signal. The charging device can determine that it is connected to the breast pump when it detects that the first signal level has changed to a low-level signal.

[0027] In another embodiment, the first electrical signal can also be implemented as a high-level signal. Specifically, when the breast pump is not confirmed to be connected to the charging device, the second signal transmission terminal can be pulled up to make its first electrical signal a high-level signal. When the charging device is not confirmed to be connected to the breast pump, the second signal transmission terminal can be pulled down to make its level signal a low-level signal. When the first signal transmission terminal is connected to the second signal transmission terminal, the second signal transmission terminal is pulled up by the first signal transmission terminal to make the level signal of the first signal transmission terminal change to a high-level signal. The charging device can determine that it is connected to the breast pump when it detects that the level signal of the first signal transmission terminal has changed to a high-level signal.

[0028] It should be noted that when the breast pump detects that the current at the power input interface is greater than the preset current threshold, it can switch the second signal transmission end to the port on the breast pump used to transmit communication data, such as the communication pin of the control circuit, and then send a handshake signal through the port to initiate the handshake process with the charging device.

[0029] In this embodiment, the handshake process is a two-way authentication and communication initialization protocol executed by the breast pump and charging device when they confirm their connection. This protocol ensures the legitimacy of both parties' identities, reliable communication, and protocol consistency. The handshake process is considered successful when both parties confirm that they have successfully shaken hands with each other. Optionally, the breast pump can send a handshake command via a second signal transmission terminal when confirming its connection with the charging device. After receiving the handshake command, the charging device performs a matching operation. Upon successful matching, the charging device confirms that the handshake with the breast pump has been successful and sends a response command via the second signal transmission terminal. After receiving the response command, the breast pump confirms that the handshake with the charging device has been successful and they begin data exchange.

[0030] Optionally, when the breast pump determines that it is connected to the charging device, it can inject a carrier wave of a specific timing into the charging circuit by controlling the switching on and off of the switch on the charging circuit between the power input interface and the power output interface. After the charging device recognizes the carrier wave, it matches its timing. After successful matching, it injects another carrier wave of a specific timing into the charging circuit by controlling the switching on and off of the switch on the charging circuit between the power input interface and the power output interface. After the breast pump successfully matches the timing, it determines that it has successfully shaken hands with the charging device.

[0031] It should be noted that the preset current threshold is a current value lower than the charging current output by the charging device, so that when the charging device outputs charging current to the power input interface through the power output interface, the breast pump can detect that the current at the power input interface is greater than the preset current threshold, and determine that it is connected to the charging device accordingly. The specific value can be set according to the magnitude of the charging current.

[0032] In this embodiment, when the breast pump assembly and the charging device are first connected, the breast pump assembly has not yet confirmed its connection with the charging device. Its second signal transmission terminal actively sends a first electrical signal, causing a recognizable signal change at the first signal transmission terminal of the charging device. Upon detecting the corresponding signal change, the charging device confirms its connection with the breast pump and sequentially outputs charging current to the breast pump through the power output interface and the power input interface to charge the breast pump. When the breast pump detects that the current at the power input interface is greater than a preset current threshold, it confirms its connection with the charging device and initiates a handshake process to attempt to establish a communication connection. Once the breast pump and the charging device confirm a successful handshake, a communication link is established with the charging device, and data is exchanged through the communication link.

[0033] This setup allows the charging device to wirelessly communicate with a mobile app during data exchange with the breast pump. Users can then send control signals to the breast pump via the app, which in turn transmits these signals to the charging device. The charging device adjusts its charging process accordingly, such as activating a slow charging mode for nighttime use or pausing charging to reduce temperature rise, thus meeting individual user needs.

[0034] On the other hand, the charging device can upload its own working status and management information (such as current battery level, real-time temperature, number of charge and discharge cycles, health assessment, charging mode, protection event records, etc.) to the breast pump, and synchronize it to the APP. This allows users to not only view the breast pumping data, but also to have a comprehensive understanding of the transparent information in the charging process, thus improving the user experience.

[0035] Furthermore, during data interaction with the breast pump, the charging device can also obtain battery information such as battery level, battery health, and battery temperature. This allows the charging device to manage the charging of the breast pump's battery based on its operating parameters. For example, when the battery temperature is detected to be too high, it can automatically switch to trickle charging or pause charging to prevent overheating and damage to the battery cells. Alternatively, if the battery level is too low, it can activate fast charging mode to shorten the waiting time. Compared to existing charging devices that only provide electrical energy, this not only ensures charging safety and extends battery life but also improves charging efficiency, thereby enhancing the user experience.

[0036] Furthermore, during data interaction with the breast pump, the charging device acquires the breast pump's operating parameters, such as the optimal operating mode set by the user, and stores them. This allows the new breast pump, which the user has purchased, to obtain the previously set optimal operating mode from the charging device when the old breast pump is lost, eliminating the need for the user to reset it and improving the user experience.

[0037] In one embodiment of this application, reference is made to Figure 3 The step of determining the connection status with the breast pump based on the signal changes received at the first signal transmission terminal includes: Step S110: The charging device is configured to: when it detects that the signal received by the first signal transmission terminal is a first electrical signal, acquire the duration of the first electrical signal at the first signal transmission terminal and use it as the second duration; Step S120: When the second duration is detected to reach the second preset duration, it is determined that the breast pump is connected to itself; When it is detected that the signal received by the first signal transmission terminal is not the first electrical signal, or the second duration is less than the second preset duration, it is determined that the breast pump is not connected to itself.

[0038] The second preset duration is the lower limit of the effective time for which the charging device requires the first electrical signal to be maintained continuously. It can be set to a value of 20ms to 100ms, and the specific value can be set by the R&D personnel according to the actual situation.

[0039] It should be noted that during the connection process between the charging device and the breast pump, the first and second signal transmission terminals may experience multiple microsecond-level level fluctuations due to mechanical bouncing at the moment of contact. If a connection is determined solely based on the detection of the first electrical signal, it can easily lead to false triggering of the system. For example, a single insertion might be mistakenly interpreted as multiple connections, resulting in repeated handshakes, abnormal charging, or data mistransmission.

[0040] To address this, this embodiment introduces a duration verification mechanism: the charging device only determines a valid connection when it confirms the continuous and stable existence of the first electrical signal, i.e., when the duration of the first electrical signal at the first signal transmission end reaches a second preset duration. This effectively filters out contact jitter and transient interference, improving the accuracy and stability of connection identification.

[0041] It should be noted that when the signal received at the first signal transmission end is not the first electrical signal, it usually indicates that the charging device has not yet established a valid connection with the breast pump—for example, the charging box is empty, an incompatible device is placed inside, or the contacts are not making contact / have poor contact. When the second duration is less than the second preset duration, it usually indicates that the breast pump was briefly touched and then removed (e.g., by user error or repositioning) or that the contact was interrupted due to mechanical vibration or oxidation, failing to maintain a stable communication connection. All of the above situations constitute unstable and invalid connections, and the charging device accordingly determines that the connection is "not engaged," thereby preventing accidental charging and ensuring safe and reliable operation.

[0042] In one embodiment of this application, reference is made to Figure 4 The handshake process for initiating the charging device includes: Step S310: The breast pump is configured to send a handshake command via the second signal transmission terminal when it detects that the current received at the power input interface is greater than a preset current threshold. Step S320: The charging device is configured to: upon receiving the handshake command via the first signal transmission terminal, determine that the handshake with the breast pump has been successful, and output a response signal to the breast pump; Step S330: The breast pump is configured to determine that a handshake with the charging device has been successfully completed upon receiving a response signal.

[0043] It should be noted that when the breast pump detects that the current at the power input interface is greater than the preset current threshold, it can confirm that it is in a stable power supply state, and then determine that it has completed the connection with the charging device - while the charging device has already completed the connection recognition beforehand.

[0044] Based on this, the breast pump actively sends a handshake command to initiate a communication request. After receiving the command, the charging device performs a validity check (such as device type, checksum, etc.), and confirms the handshake is successful when the check is successful, and outputs a specific response signal. After the breast pump detects the response signal, it can confirm that the charging device has not only received the handshake command, but has also completed the matching verification, thus confirming the handshake is successful in both directions, laying the foundation for subsequent safe and reliable data interaction.

[0045] In one embodiment, the response signal can be a first current signal / first voltage signal output by the charging device through its power output interface when it receives the handshake command via the first signal transmission terminal. This allows the breast pump to detect the first current signal / first voltage signal and determine that the handshake with the charging device has been successful. The first current signal / first voltage signal is an identifiable electrical signal actively modulated by the charging device at its power output interface as a response. For example, upon receiving the handshake command, the charging device performs a preset number of restart operations, such as 2-3 times, to output intermittent current / voltage. The breast pump determines that the handshake with the charging device has been successful when it detects the intermittent current / intermittent voltage. Alternatively, upon receiving the handshake command, the charging device briefly modulates the output current or voltage according to a preset timing sequence (e.g., a current step of +150mA for 100ms, or a voltage pulse of +80mV for 50ms) as a response signal for a successful handshake.

[0046] In another embodiment, the response signal may also be a response command sent by the charging device through the second signal transmission terminal when the handshake command is received through the first signal transmission terminal, serving as a response signal for successful handshake.

[0047] In another embodiment, the response signal may include the aforementioned first current signal / first voltage signal and response command. The charging device is configured to: upon receiving the handshake command via the first signal transmission terminal, output the first current signal / first voltage signal via the power output interface, and also send the response command via the second signal transmission terminal; the breast pump is configured to: upon detecting that the first current signal / first voltage signal has been received at the power input interface, and upon receiving the response command via the second signal transmission terminal, determine that the handshake with the charging device has been successful.

[0048] With this setup, the breast pump confirms a successful handshake with the charging device only by receiving a first current signal / first voltage signal and a response command. This significantly improves the reliability and anti-interference capability of communication establishment, laying a highly robust foundation for subsequent data interaction.

[0049] It should be noted that when the charging device and the breast pump establish a connection, they need to communicate with each other to perform a handshake process. This communication requires a certain preparation time. Therefore, in one embodiment, the charging device starts a first timer when it outputs charging current to the breast pump sequentially through the power output interface and the power input interface. When the duration of the first timer reaches a third preset duration, the handshake command is received through the first signal transmission terminal. The third preset duration is the time required for the charging device and breast pump to prepare for communication; it can be 100ms, or it can be set by the developers according to actual needs.

[0050] With this configuration, the charging device does not immediately receive the handshake command sent by the breast pump after outputting the charging current. Instead, it receives the handshake command only after a third preset time period. This provides sufficient time for the charging device and the breast pump to prepare for communication, thus fundamentally avoiding handshake failure due to incomplete preparation.

[0051] It should be noted that during the connection process between the breast pump and the charging device, factors such as contact jitter, mechanical misalignment, incomplete magnetic attraction, or external vibration may cause a momentary disconnection or poor contact between the first and second signal transmission terminals. This can lead to the loss or distortion of the handshake command sent by the breast pump during transmission, resulting in handshake failure. To address this, in one embodiment, when the breast pump detects charging current at the power input interface, it sends a handshake command through the second signal transmission terminal every fourth preset time interval until a response is received. This configuration mitigates the risk of losing a single handshake command under common physical interference such as contact jitter and momentary disconnection. By retransmitting the command every fourth preset time interval, the brief contact interruption window can be covered, ensuring that at least one command is successfully delivered when the connection is stable, significantly improving the handshake success rate. The fourth preset time interval is a fixed time interval between each handshake command transmission, which can be between 100ms and 500ms, or can be set by the developers according to actual needs.

[0052] In one embodiment of this application, the number of breast pumps is multiple, each breast pump has a unique identifier, and the charging device has multiple charging slots for accommodating the breast pumps, each charging slot having a power output interface and a first signal transmission terminal; Reference Figure 5 The control method further includes: Step S500: The charging device is configured to: when it detects that the breast pump is connected to any charging slot, read the identity identifier sent when the breast pump starts the handshake process, and compare the read identity identifier with the identity identifier of the target breast pump that is preset to be paired with the charging slot; Step S600: If the identity identifier does not meet the target conditions, trigger the first prompt action to prompt the user that the breast pump is placed incorrectly, and stop outputting charging current to the breast pump through the power output interface and the power input interface; If the identity identifier meets the target conditions, the first signal transmission terminal of the charging device is driven to establish a communication link with the second signal transmission terminal of the breast pump.

[0053] It should be noted that each charging slot is pre-charged with a pre-paired target breast pump before leaving the factory. This allows the charging device to accurately identify the breast pump and obtain and store the corresponding data—ensuring that the operation and charging information of different breast pumps are archived independently, avoiding data confusion, and guaranteeing the accuracy and traceability of records. However, if a user mistakenly places any breast pump into an incompatible charging slot, data confusion may occur.

[0054] In this embodiment, when the charging device detects that the identification of the breast pump placed in the charging slot does not match the target breast pump paired with the charging slot, it determines that the breast pump's identification does not meet the target conditions and triggers a first prompt action, such as issuing a voice prompt, flashing a light, or vibrating, to alert the user that the breast pump has been placed incorrectly. Since the charging device has not yet established a communication link with the breast pump at this time, it cannot obtain the breast pump's battery status. Directly charging the breast pump without a connection could potentially affect the battery; therefore, the charging device stops charging the breast pump at this point to avoid potential battery safety hazards. Conversely, when the charging device detects that the identification of the breast pump placed in the charging slot matches the target breast pump paired with the charging slot, it determines that the breast pump's identification meets the target conditions and drives the charging device and the breast pump to establish a communication link, enabling data exchange between them.

[0055] It is understandable that in practical applications, users may not be able to promptly detect the initial prompt from the charging device, causing the breast pump's identification to fail to meet the target conditions for an extended period, resulting in the charging device not charging the breast pump for a prolonged time. Consequently, the breast pump may not be able to be used the next time due to low battery, impacting the user experience, and the charging device will also be unable to obtain breast pump-related data generated during recent use. To address this, in one embodiment, referring to... Figure 6 The charging device is further configured to: Step S610: Obtain the duration during which the identity identifier does not meet the target condition, and use it as the first duration; Step S611: When the first duration exceeds the first preset duration, establish a communication link with the breast pump, output charging current to the breast pump through the power output interface and the power input interface, and associate and record the data obtained from charging and data interaction of the breast pump as the data of the target breast pump preset to be paired with the charging slot.

[0056] It should be noted that the first preset duration is the threshold of the waiting time for the user to correct the operation after the charging device detects that the identity of the breast pump is inconsistent with the preset pairing of the charging slot. It can be set to about 30 seconds, or you can set it yourself according to the actual situation.

[0057] It should be noted that when the charging device first interacts with the breast pump, if the identification does not match, a polling mechanism will be used to periodically re-attempt identification and begin timing. If the user fails to notice the prompt and the identification mismatch persists for more than a first preset time, the charging device establishes a communication link with the breast pump and outputs charging current to the breast pump via the power output and power input interfaces to charge it. The charging device also associates and stores charging-related information generated during the charging process, as well as data sent during data interaction, with the target breast pump in the incorrect charging slot. For example, if the left breast pump is placed in the right charging slot, this charging is recorded as charging the right breast pump, and the charging and data interaction information generated by the left breast pump are associated and stored with the right breast pump.

[0058] With this setup, when the charging device determines that the breast pump has been placed in the wrong charging slot for too long, it will directly charge the breast pump, ensuring that the user can use a fully charged breast pump next time. It also establishes a direct communication link with the breast pump, allowing the charging device to obtain the milk-related data generated during the pump's operation. This prevents the user from losing a complete milk-expressing data record or causing charging interruption due to a single incorrect placement, thus improving the user experience.

[0059] In practical applications, users may repeatedly place the same breast pump into a non-preset slot due to ease of operation, storage habits, or unclear labeling of the charging case, causing a prompt to be triggered every time it is used, resulting in a highly disruptive user experience. To address this, in one embodiment, refer to... Figure 7 If the identity identifier does not meet the target conditions, triggering the first prompt action to notify the user that the breast pump is placed incorrectly includes: Step S620: The charging device is configured to: after triggering the first prompt action, perform a first count of events in which the identity of the breast pump does not meet the target conditions; Step S621: When the value of the first count is greater than the first preset value, send the position correction prompt of the breast pump to the external terminal, and when the position modification instruction returned by the external terminal is received within the preset response time after sending the position correction prompt, update the identity of the breast pump to the pairing target of the charging slot. And / or, after sending a location correction prompt to an external terminal, obtain the increment of the first count, and when the increment of the first count is greater than a second preset value, update the identity of the breast pump to the pairing target of the charging slot.

[0060] In this embodiment, the first counter is used to count the number of times the user continues to place the same breast pump into the current charging slot after the first prompt action has been sent, i.e., the number of times the breast pump's identification does not meet the target condition. When the value of the first counter reaches a first preset value, such as 3 to 5 times, the charging device determines that this high-frequency misplacement event is the user's actual placement habit in practical applications, and sends a corresponding position correction prompt to the external terminal to prompt the user whether to use the breast pump as the target breast pump for pairing with the charging slot. After receiving the position correction prompt, the user can send a position modification command through the external terminal, so that the charging device will use the breast pump as the target breast pump for pairing with the charging slot when it receives the position modification command. The first preset value is the number of times the event of the identification not meeting the target condition has exceeded the random error range, such as 2 to 5 times, and can also be set according to the actual situation.

[0061] After sending the position correction command to the external terminal, the charging device also obtains the increment of the first count, which is the number of times the user has repeated the incorrect insertion event after sending the position correction command. If the increment of the first count is greater than a second preset value, it determines that the user is still repeating the incorrect insertion event and has not responded to the position correction prompt. In this case, the charging device can directly use this breast pump as the target breast pump for pairing with the charging slot to adapt to the user's usage habits. The second preset value is used to measure whether the user continues to place the same breast pump into the current charging slot after the position correction prompt has been sent, for example, 2 to 5 times, and can also be set according to actual conditions.

[0062] This setup, through a "first count" mechanism, allows the charging device to identify a repetitive user behavior pattern. When it detects a user repeatedly inserting the same breast pump into the "incorrect" slot, it's no longer simply viewed as an error requiring correction, but rather interpreted as a potential new habit the user wants to establish. A location correction prompt is sent to guide the user to re-bind the breast pump to align with their usage habits and meet their personalized needs. Furthermore, by using the increment of the first count to determine when the user consistently ignores the location correction prompt, the device automatically re-binds the breast pump to the repeatedly misplaced charging slot. This ensures the breast pump's usability while respecting the user's actual usage preferences, achieving seamless self-adaptation.

[0063] In one embodiment of this application, reference is made to Figure 8 The control method further includes: Step S700: The charging device is configured to: after establishing a communication link with the breast pump, acquire the historical operating parameters of the breast pump host; Step S800: Perform frequency statistics on the historical working parameters to determine the parameter combination that appears most frequently; Step S900: Store the most frequently occurring parameter combination as the optimal working mode parameter package of the breast pump, and send the optimal working mode parameter package of the breast pump to the breast pump so that the breast pump can work in the optimal working mode.

[0064] It should be noted that historical operating parameters include the historical operating time of the breast pump each time it is used, the historical suction frequency of the breast pump each time it is used, or the historical milk volume of the breast pump each time it is used. The most frequent parameter combination is the operating data that the user uses most frequently during the history of the breast pump, such as the most frequently used operating time, the most frequently used suction frequency and suction power parameters of the pump, and the most frequently expressed milk volume parameters during the history of multiple uses.

[0065] When using a breast pump for an extended period, users will continuously adjust the aforementioned operating parameters according to their own needs. After the adjustment is completed, they will continue to use the adjusted operating parameters to ensure that the breast pump's milk expression function meets their needs. For users, the operating mode of the breast pump based on their own adjusted operating parameters is the optimal operating mode. Therefore, the charging device can use the most frequently occurring parameter combination as the optimal operating mode parameter package for the breast pump and send it to the breast pump so that the breast pump can work in the optimal operating mode.

[0066] This setup has two advantages. First, the most frequently used parameter combinations are continuously adjusted based on historical operating parameters to ensure the breast pump's optimal operating mode meets the user's most recent needs. Second, the charging device can store the optimal operating mode parameter package. When the user switches to another breast pump, the pump can directly retrieve the optimal operating mode parameter package from the charging device, significantly reducing the tedious manual adjustment of the pump's operating parameters to the user's desired settings and improving the user experience.

[0067] This application also proposes a breast pump assembly, including a breast pump and a charging device. The charging device has a power output interface and a first signal transmission terminal, and the breast pump has a power input interface and a second signal transmission terminal. When the charging device is connected to the breast pump, the power input interface is connected to the power output interface, and the second signal transmission terminal is connected to the first signal transmission terminal. The breast pump and the charging device are used to operate the control method of the breast pump assembly described above.

[0068] It is worth noting that since the breast pump assembly of this application is based on the control method of the breast pump assembly described above, the embodiments of the breast pump assembly of this application include all the technical solutions of all embodiments of the control method of the breast pump assembly described above, and the technical effects achieved are exactly the same, so they will not be repeated here.

[0069] In one embodiment of this application, reference is made to Figure 9 The charging device includes a first battery circuit 11, a first control circuit 12, and a first switching circuit 13. The first battery circuit 11 is connected to the power output interface. The first control circuit 12 is connected to the controlled terminal of the first switching circuit 13 and the controlled terminal of the first battery circuit 11. The first terminal of the first switching circuit 13 is connected to the first signal transmission terminal. The first control circuit 12 has a status detection interface and a first signal transmission interface. The second terminal of the first switching circuit 13 is connected to the status detection interface. The third terminal of the first switching circuit 13 is connected to the first signal transmission interface. The breast pump includes a second battery circuit 21, a second control circuit 22, and a second switching circuit 23. The second battery circuit 21 is connected to the power input interface. The second control circuit 22 is connected to the controlled end of the second switching circuit 23. The first end of the second switching circuit 23 is connected to the second signal transmission end. The second control circuit 22 has a second signal transmission interface. The second end of the second switching circuit 23 is connected to the second signal transmission end. The third end of the second switching circuit 23 is connected to a first electrical signal.

[0070] In this embodiment, both the first control circuit 12 and the second control circuit 22 can be implemented using a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or a SOC (System-on-Chip).

[0071] In this embodiment, the status detection interface is the port of the first control circuit 12 used to detect signal changes. When the status detection interface is connected to the first signal transmission terminal, the first control circuit 12 detects signal changes at the first signal transmission terminal via the status detection interface. The first signal transmission interface includes a signal transmission terminal (Rx) and a signal transmitting terminal (Tx) of the first control circuit 12. Since the first signal transmission terminal adopts a single-wire design (only one physical wire) or a single-ended design, it cannot transmit and receive signals simultaneously. Therefore, the first control circuit 12 needs to dynamically switch the enabling states of its internal signal transmitting terminal and signal transmission terminal according to the communication stage. The second signal transmission interface includes a signal transmission terminal (Rx) and a signal transmitting terminal (Tx) of the second control circuit 22. Since the second signal transmission terminal adopts a single-wire design (only one physical wire) or a single-ended design, it cannot transmit and receive signals simultaneously. Therefore, the second control circuit 22 needs to dynamically switch the enabling states of its internal signal transmitting terminal and signal transmission terminal according to the communication stage.

[0072] In this embodiment, the first switching circuit 13 is used to control the connection between the first signal transmission terminal and one of the status detection interface and the first signal transmission interface, and the second switching circuit 23 is used to control the connection between the second signal transmission terminal and one of the second signal transmission interface and the first electrical signal.

[0073] Optionally, the first switching circuit 13 and the second switching circuit 23 can be implemented using a single-pole double-throw switch. The common terminal of the single-pole double-throw switch is equivalent to the first terminal of the first switching circuit 13 and the second switching circuit 23, and the two moving contacts of the single-pole double-throw switch are equivalent to the second and third terminals of the first switching circuit 13 and the second switching circuit 23. The first control circuit 12 controls the lever on the single-pole double-throw switch to open the corresponding path.

[0074] Optionally, the first switching circuit 13 and the second switching circuit 23 can also be implemented using two switching components. One switching component of the first switching circuit 13 is disposed between the first signal transmission end and the status detection interface, and the other switching component of the first switching circuit 13 is disposed between the first signal transmission end and the first signal transmission interface. One switching component of the second switching circuit 23 is disposed between the second signal transmission end and the second signal transmission interface, and the other switching component of the second switching circuit 23 is disposed between the second signal transmission end and the first electrical signal. The first switching circuit 13 defaults to conducting the path between the status detection interface and the first signal transmission end, and the second switching circuit 23 defaults to conducting the path between the second signal transmission end and the first electrical signal, so that when the charging device and the breast pump are connected, the first electrical signal can be transmitted to the second signal transmission end, allowing the charging device to detect signal changes at the first signal transmission end.

[0075] In this embodiment, the third terminal of the second switching circuit 23 can be grounded so that its output first electrical signal is low-level. Alternatively, the third terminal of the second switching circuit 23 can be connected to a pull-up circuit so that its output first electrical signal is high-level. When the first electrical signal is low-level, the charging device can pull up the level of the status detection interface so that when the charging device is connected to the breast pump, the low-level signal can pull down the level of the status detection interface. When the charging device detects the low-level signal, it determines that it is connected to the breast pump. Conversely, the third terminal of the second switching circuit 23 can be connected to a pull-up circuit so that its first electrical signal is high-level. Correspondingly, the charging device can pull down the level of the status detection interface so that when the charging device is connected to the breast pump, the high-level signal can pull up the level of the status detection interface. When the charging device detects the high-level signal, it determines that it is connected to the breast pump.

[0076] In this embodiment, the first battery circuit 11 is used to supply power to the electrical components of the breast pump, and the second battery circuit 21 is used not only to supply power to the first battery circuit 11, but also to supply power to the electrical components of the charging device.

[0077] In this embodiment, when the breast pump and charging device are connected, a first electrical signal is sent to the first signal transmission terminal via the second signal transmission terminal, causing a change in the signal at the first signal transmission terminal. When the first control circuit 12 determines that the breast pump and charging device are connected based on the signal change received at the first signal transmission terminal, it controls the first battery circuit 11 to output charging current to the power input interface and controls the first switching circuit 13 to open the path between the first signal transmission terminal and the first signal transmission interface, thereby preparing for subsequent handshake communication with the breast pump. When the breast pump detects that the current at the power input interface is greater than a preset current threshold, it initiates the handshake process with the charging device.

[0078] It is understood that the handshake process is the same as that in the above embodiments, and will not be described in detail here.

[0079] This setup allows the charging device to wirelessly communicate with a mobile app during data exchange with the breast pump. Users can then send control signals to the breast pump via the app, which in turn transmits these signals to the charging device. The charging device adjusts its charging process accordingly, such as activating a slow charging mode for nighttime use or pausing charging to reduce temperature rise, thus meeting individual user needs.

[0080] On the other hand, the charging device can upload its own working status and management information (such as current battery level, real-time temperature, number of charge and discharge cycles, health assessment, charging mode, protection event records, etc.) to the breast pump, and synchronize it to the APP. This allows users to not only view the breast pumping data, but also to have a comprehensive understanding of the transparent information in the charging process, thus improving the user experience.

[0081] Furthermore, during data interaction with the breast pump, the charging device can also obtain battery information such as battery level, battery health, and battery temperature. This allows the charging device to manage the charging of the breast pump's battery based on its operating parameters. For example, when the battery temperature is detected to be too high, it can automatically switch to trickle charging or pause charging to prevent overheating and damage to the battery cells. Alternatively, if the battery level is too low, it can activate fast charging mode to shorten the waiting time. Compared to existing charging devices that only provide electrical energy, this not only ensures charging safety and extends battery life but also improves charging efficiency, thereby enhancing the user experience.

[0082] Furthermore, during data interaction with the breast pump, the charging device acquires the breast pump's operating parameters, such as the optimal operating mode set by the user, and stores them. This allows the new breast pump, which the user has purchased, to obtain the previously set optimal operating mode from the charging device when the old breast pump is lost, eliminating the need for the user to reset it and improving the user experience.

[0083] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
