Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a base station and a cleaning system. Background Technology

[0002] With the increasing popularity of household cleaning appliances, cleaning equipment systems with automatic recharging and automatic dust collection functions (such as dust collection base stations for handheld / upright vacuum cleaners, or dust collection and parking base stations for sweeping and mopping devices) are widely used. Base stations are typically used to provide parking support for the main cleaning unit, recharge its power, and transfer and collect dust from the dust box / dust bin, thereby reducing the frequency of user maintenance and improving ease of use.

[0003] In existing technologies, most cleaning units are powered by rechargeable batteries. To meet the needs of large homes, long-term continuous cleaning, or high-power modes, some products adopt a removable battery pack design, allowing users to extend battery life by replacing the battery pack. Correspondingly, various battery replenishment methods have emerged in the market, such as: the cleaning unit being placed at a base station for charging; or users placing a spare battery pack in the base station's storage area, charging dock, or charging slot for replenishment.

[0004] However, some shortcomings still exist in the above solutions: First, while some base stations are replenishing power to the cleaning host, they cannot simultaneously meet the power replenishment needs of the backup battery pack. Users often need to switch between different charging objects or need to configure an additional independent charger, which makes the charging process cumbersome, space-consuming, and easy to forget. Second, even if some solutions support replenishing power to multiple batteries, they are often limited by power supply capacity, control strategies, or structural layout, resulting in low charging efficiency and inflexible switching of charging objects, which in turn affects the continuous operation experience. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of how to improve the adaptability and user experience of base stations in multi-battery charging scenarios without increasing the user's operational burden, while taking into account safety, reliability and ease of maintenance, and to provide a base station and cleaning system.

[0006] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention.

[0007] According to one aspect of the present invention, a base station is provided, comprising: Base station main body; A charging interface is provided on the base station body, including a first interface that interfaces with a first battery pack provided on the cleaning host and a second interface that interfaces with a second battery pack. The charging circuit includes a first circuit connected to the first interface and a second circuit connected to the second interface; The control unit, located inside the base station body, controls the conduction of the first circuit and the second circuit respectively; The first battery pack and the second battery pack are interchangeable in powering the cleaning unit; the control unit is configured to: When the first battery pack is connected to the first interface, the first circuit is turned on. When the second battery pack is connected to the second interface, the second circuit is turned on. When the first battery pack and the second battery pack are respectively connected to the first interface and the second interface, the first circuit is controlled to be turned on and the second circuit is turned on.

[0008] By setting charging interfaces on the base station body for connecting to the first battery pack on the cleaning host and the second battery pack respectively, and configuring the first circuit and the second circuit corresponding to the two interfaces in the base station, the base station can establish relatively independent charging paths for different charging objects in terms of structure. This allows the base station platform to simultaneously meet the two types of energy replenishment needs: charging the battery pack that is parked with the host and charging the independent battery pack. This improves the adaptability and user convenience in multi-battery usage scenarios.

[0009] Finally, the first and second battery packs can alternately power the cleaning host, so the power replenishment of the two battery packs can be uniformly managed at the base station side, allowing users to flexibly switch between the working battery pack and the backup battery pack, thereby achieving more continuous and stable cleaning operation support without significantly increasing additional equipment.

[0010] In some exemplary embodiments of the present invention, based on the foregoing scheme, When the first battery pack and the second battery pack are respectively connected to the first interface and the second interface, and the first battery pack meets the first preset condition, and the second battery pack meets the second preset condition, the first circuit is turned on and the second circuit is turned on. The first preset condition includes: the first battery pack is not fully charged; the second preset condition includes: the second battery pack is not fully charged.

[0011] By setting corresponding preset conditions for the first and second battery packs respectively, under the premise that the first battery pack is connected to the first interface and the second battery pack is connected to the second interface, the first circuit is activated only when the first battery pack meets the first preset condition and the second circuit is activated only when the second battery pack meets the second preset condition. This ensures that the two charging outputs match the actual charging needs of their respective battery packs, avoiding invalid charging and unnecessary energy consumption caused by activating the circuit when the battery pack is fully charged or does not need to be recharged. This improves the system's energy efficiency and the precision of charging management.

[0012] Secondly, the first preset condition is limited to the first battery pack being in a non-fully charged state, and the second preset condition is limited to the second battery pack being in a non-fully charged state. This enables the base station to make independent judgments and control based on the charging termination state of each battery pack: when a battery pack is fully charged, only the corresponding circuit remains off without affecting the other circuit from continuing to charge. This reduces the waiting time caused by a single battery pack being fully charged in parallel charging scenarios, thereby improving the efficiency of dual-battery charging and the continuity of user experience.

[0013] Furthermore, using the docking in place and the non-fully charged state as the circuit conduction access condition can reduce the risk of erroneous power-on when docking is unstable or the state is misjudged, and reduce battery aging and device temperature rise accumulation caused by long-term float charging after full charge, thereby improving the safety, reliability and battery pack life performance of the charging process.

[0014] In some exemplary embodiments of the present invention, based on the foregoing scheme, the control unit is configured as follows: When the first battery pack does not meet the first preset condition, the first circuit is controlled to shut down; and / or When the second battery pack does not meet the second preset condition, the second circuit is controlled to shut down.

[0015] By actively controlling the first circuit to remain off when the first battery pack does not meet the first preset condition, it is possible to avoid erroneous power-on output when the first battery pack has not requested charging, has not completed handshake authentication, or has not met the safety threshold. This reduces the risk of no-load output, erroneous charging, and abnormal energy output, and improves the safety and reliability of the first circuit charging control.

[0016] By actively controlling the second circuit to remain off when the second battery pack does not meet the second preset condition, unexpected charging behavior when the second battery pack is not properly connected, has poor contact, or is in an abnormal state can be suppressed, reducing device temperature rise and losses caused by invalid charging and repeated start-stop, thereby improving the stability of the second circuit charging process and device life.

[0017] Secondly, since the first and second circuits adopt the fail-safe strategy of default shutdown when not enabled according to the corresponding preset conditions, even if the charging permission status of either battery pack changes or is temporarily lost, it can ensure that the corresponding charging circuit quickly returns to the safe state, avoiding the mutual transmission or superposition of abnormal states when the two circuits are charging in parallel, thereby enhancing the overall safety redundancy and robustness of the base station in the dual-circuit working scenario.

[0018] In some exemplary embodiments of the present invention, based on the foregoing scheme, the control unit is further configured to: before controlling the first circuit and / or the second circuit to be turned on. Perform a communication handshake and / or authentication on the first battery pack and / or the second battery pack; When the communication handshake is successful and / or the identity authentication is passed, it is determined that the first preset condition and / or the second preset condition is met.

[0019] By performing a communication handshake and / or authentication on the corresponding first and / or second battery packs before activating the first and / or second circuits, the battery pack type, status, and legitimacy can be confirmed before the charging circuit is powered on. This avoids unidentified, mismatched, or abnormal battery packs from being connected, leading to mischarging, parameter mismatch, and potential safety hazards, thereby improving the safety and reliability of the charging process.

[0020] Secondly, the first preset condition and / or the second preset condition are only determined to be met when the communication handshake is successful and / or the identity authentication is passed. This allows the preset conditions to serve as valid credentials for charging permission, binding the circuit conduction condition with the authorization status on the battery pack side. This enables controlled enabling and failure safety control of the charging circuit, reducing the probability of blind power-on, no-load output, or abnormal energy output.

[0021] Furthermore, by combining the handshake / authentication mechanism with the independent control of the first and second circuits, independent verification and authorization can be performed on the two battery packs in the dual-circuit parallel charging scenario. This allows the base station to ensure the charging safety of one battery pack while preventing overall charging interruption or malfunction due to authentication failure or abnormal state of the other battery pack, thereby improving the stability and anti-interference capability in dual-charging mode.

[0022] In some exemplary embodiments of the present invention, based on the foregoing scheme, the control unit is configured as follows: When the voltage of the first battery pack and / or the second battery pack is detected to have reached a preset full charge threshold, the corresponding charging circuit is shut off to stop charging the corresponding battery pack; and / or When the first battery pack and / or the second battery pack outputs a full charge indication message, the corresponding charging circuit is controlled to shut down to stop charging the corresponding battery pack.

[0023] By controlling the corresponding charging circuit to shut down and stop charging in a timely manner when the voltage of the first battery pack and / or the second battery pack reaches the preset full charge threshold, the risk of overcharging caused by the battery pack continuing to input energy when it is close to full charge can be avoided, and safety hazards such as battery overheating, bulging and capacity decay can be reduced, thereby improving the safety of the charging process and the battery life.

[0024] Secondly, by controlling the corresponding charging circuit to shut down and stop charging when the first battery pack and / or the second battery pack outputs a full charge indication, the charging termination action of the base station can be kept consistent with the charging status determination on the battery pack side, avoiding misjudgments caused by relying solely on a single voltage threshold (such as voltage drift under different temperatures, loads, or battery health conditions), thereby improving the accuracy of full charge determination and the robustness of charging control.

[0025] Furthermore, triggering shutdown based on at least one of two criteria—voltage threshold determination and full charge indication information determination—can create a more redundant charging termination mechanism. This allows each battery pack to independently complete full charge exit based on its own state in a dual-circuit parallel charging scenario, reducing ineffective energy consumption and device temperature rise caused by prolonged float charging, thereby improving the stability and energy efficiency of dual-charging operation of the base station.

[0026] In some exemplary embodiments of the present invention, based on the foregoing scheme, the first circuit is provided with a first charging controller, and the second circuit is provided with a second charging controller. The first charging controller and the second charging controller respectively perform constant current and constant voltage charging control on the first battery pack and the second battery pack.

[0027] By setting a first charging controller and a second charging controller in the first circuit and the second circuit respectively, and having the two charging controllers perform constant current and constant voltage charging control on the first battery pack and the second battery pack respectively, the base station can achieve independent adjustment and independent closed-loop control for the charging process of different battery packs. This avoids charging instability or control distortion caused by the mutual coupling of charging parameters when multiple batteries are charged in parallel, thereby improving the stability and consistency of dual-circuit charging.

[0028] Secondly, constant current and constant voltage charging control can improve charging efficiency by using constant current charging when the battery is low, and smoothly converge the charging current by using constant voltage control when the battery is close to full charge. This avoids the risk of overheating and overcharging caused by rapid voltage rise or continuous high current input, thereby improving the safety and lifespan of the battery pack while ensuring charging speed.

[0029] Furthermore, since the first charging controller and the second charging controller implement charging curve control for different battery packs respectively, when the charging curve of a certain battery pack needs to be adjusted due to differences in temperature, internal resistance, health status, etc., adaptive control and protection exit can be completed without affecting the normal charging of the other battery pack, thereby improving the base station's resistance to differences and overall reliability in dual-charging operation scenarios.

[0030] In some exemplary embodiments of the present invention, based on the foregoing scheme, the base station includes a dust collection component; the control unit is configured to: In response to the cleaning host docking with the base station body, the dust collection component is controlled to perform a dust collection operation; When the dust collection operation is completed and the battery pack meets the first preset condition, the first circuit is controlled to be turned on.

[0031] By binding the activation of the first circuit with the completion of the dust collection operation and the detection of the first preset condition, the base station only starts charging the first battery pack when the dust collection process is completed and the charging permission status is met. This avoids charging anomalies and misjudgments caused by motor starting current, transient power fluctuations, or electromagnetic interference during the dust collection process, thereby improving the stability and safety of the charging process. Furthermore, this timing control of triggering dust collection upon docking and then recharging after dust collection can rationally allocate the base station's energy and execution resources during the initial docking phase, reducing the peak power superposition and temperature rise accumulation caused by simultaneous dust collection and charging. This improves the reliability and overall lifespan of the base station in multi-functional integrated scenarios and enhances the user's overall experience during the return-to-base phase.

[0032] Secondly, collecting dust before charging can eliminate electromagnetic interference from the dust collection motor, ensuring the accuracy of signals such as power detection and temperature detection.

[0033] In some exemplary embodiments of the present invention, based on the foregoing scheme, the base station further includes: The delay circuit is electrically connected to the control unit; The control unit is configured to: Output a dust collection drive signal to control the dust collection component to perform a dust collection operation; In response to the end edge of the dust collection drive signal, the delay circuit is controlled to start timing, and after the timing reaches the preset delay time, the first circuit or the second circuit is controlled to be turned on.

[0034] When faced with the requirement of "charging after dust collection is completed," those skilled in the art typically employ a direct serial logic of "charging immediately after dust collection ends," meaning the charging circuit is activated immediately after the dust collection drive signal stops to shorten the return-to-station process time. However, this invention introduces a delay circuit electrically connected to the control unit between the control unit and the charging circuit. The control unit triggers the delay circuit to start timing in response to the end edge of the dust collection drive signal. Only after the timing reaches a preset delay time is the first or second circuit activated, thereby proactively establishing a stable window between "dust collection end - charging start." This design breaks away from the technical bias that "direct serial operation is optimal," and can significantly improve system stability, anti-interference capability, and reliability without changing the basic functional objectives. For example, transient shutdown of the dust collector motor, bus ripple attenuation, contact jitter, and sensor signal stabilization can all be completed within a preset delay window, allowing charging to occur in a more stable electrical and mechanical state, reducing the risk of false triggering and repeated start-stop. At the same time, the delay circuit, as an independent timing control unit, is decoupled from the charging module, allowing the control strategy to be quickly adapted by adjusting the preset delay time. This is beneficial for modular expansion and product platform reuse under different models, power supply specifications, and dust collection components.

[0035] Secondly, the end-edge triggering, preset delay, and logical AND dual verification in this invention are not simply a stacking of timing control functions, but rather form an organic combination and construct a complete control link. Specifically, the end-edge triggering uses the moment the dust collection drive signal stops as the reference point for the delay timing, ensuring the certainty and accuracy of the timing start point and avoiding deviations caused by using fixed durations or coarse-grained polling. The preset delay provides a system stability window, allowing sufficient time for transient disturbances after the dust collection drive component stops to decay, thus creating a stable premise for the subsequent charging circuit to conduct. After the delay ends, logical AND dual verification (e.g., the preset conditions are still valid, the in-situ detection is still satisfied, etc.) is performed before the first or second circuit is allowed to conduct, further introducing safety redundancy on the basis of correct timing, avoiding erroneous power-on output when the docking status changes or the enable condition fails during the delay period. The combination of these three elements forms a closed-loop control link of precise positioning, active waiting, and dual verification, giving the charging conduction a clear time reference, a stable window, and safety redundancy, thereby achieving a synergistic improvement in stability, anti-interference, and scalability at the system level.

[0036] In some exemplary embodiments of the present invention, based on the foregoing solution, the dust collection assembly includes a dust bag; the control unit is configured to: When the dust bag is installed in place and the dust bag is detected to be in a non-full state, the dust collection component is controlled to perform a dust collection operation.

[0037] On the one hand, by checking the installation status of the dust bag before performing the dust collection operation and only allowing the dust collection component to start when the dust bag is properly installed, problems such as dust leakage, contamination of the base station interior, and abnormal air ducts caused by improperly installed or incorrectly installed dust bags can be avoided. This improves the sealing reliability of the dust collection process and the stability of system operation, reducing the user's subsequent cleaning and maintenance costs. On the other hand, by allowing the dust collection operation to be performed when the dust bag is not full, risks such as suction power reduction, airflow blockage, dust overflow, and overload of the dust collection drive component caused by continuing to collect dust when the dust bag is full can be avoided. This improves dust collection efficiency and operational safety, and extends the service life of the dust collection drive component and related parts.

[0038] Secondly, by setting the dust bag in place and the dust bag not being full as the entry conditions for dust collection operations, the base station can perform pre-verification of critical maintenance status in the scenario of automatic dust collection upon returning to the station, reducing invalid dust collection and triggering abnormal operating conditions, thereby improving the controllability of the overall workflow and the consistency of user experience.

[0039] In some exemplary embodiments of the present invention, based on the foregoing scheme, at least one indicator light is provided on the base station body; the control unit is configured to: In response to the first circuit and / or the second circuit being turned on, the indicator light is controlled to display different indication effects, which are used to indicate that the first circuit is turned on, the second circuit is turned on, and / or the first circuit and the second circuit are turned on simultaneously.

[0040] By setting indicator lights on the base station body and controlling the indicator lights to display corresponding indication effects when the first circuit and / or the second circuit is turned on, the charging status of the base station can be presented to the user in a visual way, so that the user can quickly know whether it is charging without connecting to an external terminal, thereby improving the user-friendliness and convenience of human-computer interaction.

[0041] Secondly, by corresponding the indicator effects to three states—first circuit conduction, second circuit conduction, and simultaneous conduction of both circuits—users can clearly distinguish whether the base station is currently charging the cleaning host battery pack, charging the second battery pack, or in a dual-circuit parallel charging state. This reduces misoperations and repeated waiting caused by unclear states, improving predictability and user experience consistency in dual-battery charging scenarios. When the base station experiences state changes such as two-circuit switching, parallel conduction, or charging termination, the indicator light can promptly reflect the changes in circuit conduction relationships, allowing users to determine whether the battery pack is correctly connected, whether charging has started normally, and whether dual charging is effective. This, to some extent, improves fault perception and maintenance efficiency, and reduces troubleshooting costs for users.

[0042] In some exemplary embodiments of the present invention, based on the foregoing solution, the base station body is provided with at least one button, and the control unit is configured as follows: In response to the operation command of the button, it is determined that the first preset condition and / or the second preset condition are met.

[0043] By setting buttons on the base station body and having the control unit respond to button operation commands to determine whether the first preset condition and / or the second preset condition is met, charging enable can be extended from passive triggering to user-controllable triggering. This allows users to initiate the charging process for the first battery pack and / or the second battery pack as needed in different usage scenarios, thereby improving the flexibility and convenience of charging management. Furthermore, based on button confirmation of the corresponding preset conditions, the base station can enter charging mode only with explicit user authorization, avoiding unnecessary energy consumption and interference caused by automatically entering charging when the user does not need to charge or needs to maintain silent / low power consumption, thus improving the base station's energy efficiency and user experience.

[0044] In some exemplary embodiments of the present invention, based on the foregoing solution, the control unit is further configured as follows: Obtain the first power status information of the first battery pack and the second power status information of the second battery pack; When the first power status information indicates that the power of the first battery pack is lower than a first preset threshold, it is determined that the first preset condition is met; and / or When the second power status information indicates that the power of the second battery pack is lower than the second preset threshold, it is determined that the second preset condition is met.

[0045] By acquiring the first state of charge information of the first battery pack and the second state of charge information of the second battery pack, the base station can perceive and compare the remaining power of the two battery packs in real time. This provides a data foundation for subsequent charging decisions and avoids problems such as missed charging, incorrect charging, or untimely replenishment caused by relying solely on user subjective judgment or fixed timing triggers. When the first state of charge information indicates that the first battery pack's power is below a first preset threshold, the first preset condition is met. This ensures that the charging initiation of the first circuit matches the actual replenishment needs of the first battery pack, thereby triggering charging in a timely manner when the power is insufficient and avoiding unnecessary charging intervention when the power is sufficient, thus improving the automation level and energy efficiency of charging management. When the second state of charge information indicates that the second battery pack's power is below a second preset threshold, the second preset condition is met. This allows the charging initiation of the second circuit to adaptively control the power status of the second battery pack, reducing the possibility of insufficient power in the backup battery pack when it needs to be replaced due to long-term inactivity. This improves the range guarantee capability and user experience in dual-battery rotation scenarios.

[0046] Secondly, by setting a first preset threshold and a second preset threshold respectively, and independently determining whether the corresponding preset conditions are met based on the respective power status of the two battery packs, the base station can implement differentiated triggering strategies in dual-circuit parallel charging or single-circuit charging modes, avoiding the two battery packs being treated in a one-size-fits-all manner due to their different states, thereby improving the flexibility, stability and robustness of system control.

[0047] In some exemplary embodiments of the present invention, based on the foregoing solution, the base station body is further provided with: The first in-situ detection unit is used to detect whether the first battery pack is in a docking state with the first interface; The second in-situ detection unit is used to detect whether the second battery pack is in a docking state with the second interface; The control unit is configured to: The first circuit is allowed to conduct only when the first presence detection unit detects that the first battery pack is in place; The second circuit is allowed to conduct only when the second presence detection unit detects that the second battery pack is in place; or, The first circuit and the second circuit are allowed to be turned on simultaneously only when the first presence detection unit detects that the first battery pack is in place and the second presence detection unit detects that the second battery pack is in place.

[0048] By setting a first presence detection unit and a second presence detection unit on the base station body, which are used to detect the docking presence status of the first battery pack and the first interface, and the second battery pack and the second interface, respectively, the key physical connection conditions can be pre-confirmed before the charging circuit is powered on, thereby providing a clear and observable trigger basis for charging control and improving the accuracy of base station docking status identification and the controllability of the charging process.

[0049] Secondly, the first circuit is only allowed to conduct when the first battery pack is detected to be in place by the first in-place detection unit, and the second circuit is only allowed to conduct when the second battery pack is detected to be in place by the second in-place detection unit. This ensures that the charging output is strictly bound to the actual docking state, which can avoid no-load output and mischarging in the case of battery pack not being inserted, not being inserted properly, or poor contact. It also reduces the risks of arcing, transient impacts, and abnormal heating of devices, thereby improving charging safety and interface reliability.

[0050] Furthermore, when two battery packs need to be charged simultaneously, the first and second circuits are only allowed to conduct simultaneously when both the first and second battery packs are in place. This provides clear access conditions for parallel charging of the dual circuits, preventing control disturbances or abnormal energy output caused by accidentally entering the dual charging state when only one side is connected or the connection on both sides is unstable. This improves the stability, robustness, and consistency of user experience in the dual charging mode.

[0051] In some exemplary embodiments of the present invention, based on the foregoing solution, the control unit is further configured as follows: When the first circuit and the second circuit are simultaneously turned on, the real-time charging power of the first circuit and the second circuit is obtained; If the sum of the real-time charging power exceeds a preset total power threshold, the charging current of the first circuit and / or the second circuit is reduced, or the charging mode is switched to time-sharing charging mode.

[0052] By acquiring the real-time charging power of the two circuits when the first and second circuits are simultaneously activated, the base station can perceive and quantify the power occupancy during the parallel dual-charging process in real time, thereby providing a basis for subsequent power scheduling and protection control, and avoiding uncontrollable power situations under changes in power supply capacity or differences in battery status.

[0053] Secondly, when the sum of real-time charging power exceeds the preset total power threshold, reducing the charging current of the first circuit and / or the second circuit enables the dual-circuit parallel charging to achieve adaptive derating under the condition of limited total power, suppressing the risks of bus voltage sag, adapter overload, device temperature rise accumulation and charging interruption caused by overpower, thereby improving the stability of parallel charging and the reliability of system power supply.

[0054] In addition, when the total power threshold is exceeded, the system switches to time-sharing charging mode. This allows for power reuse over time when the conditions for continuous parallel charging are not met, so that both battery packs can still receive continuous power replenishment on the same base station. This avoids the situation where a battery pack cannot be charged for a long time due to a simple shutdown, thereby improving the power replenishment efficiency and user experience in dual-battery scenarios.

[0055] Finally, the aforementioned real-time power monitoring, over-threshold judgment, and derating or time-sharing closed-loop control enable the base station to maintain predictable power boundaries and charging behavior under different adapter specifications, different battery states of charge, and different ambient temperatures, thereby enhancing the robustness of the system and reducing abnormal energy consumption and safety hazards caused by changes in operating conditions.

[0056] According to another aspect of the present invention, a cleaning system is provided, the cleaning system comprising a base station and a cleaning host, the base station comprising: Base station main body; A charging interface is provided on the base station body, including a first interface that interfaces with a first battery pack provided on the cleaning host and a second interface that interfaces with a second battery pack. The charging circuit includes a first circuit connected to the first interface and a second circuit connected to the second interface; A control unit, located within the base station body, controls the conduction of the first circuit and the second circuit respectively; wherein the first battery pack and the second battery pack can alternately power the cleaning host; the control unit is configured to: When the first battery pack is connected to the first interface, the first circuit is turned on. When the second battery pack is connected to the second interface, the second circuit is turned on. When the first battery pack and the second battery pack are respectively connected to the first interface and the second interface, the first circuit is controlled to be turned on and the second circuit is turned on.

[0057] By setting up a base station with a first interface and a second interface in the cleaning system, and configuring a first circuit and a second circuit that connect the two interfaces respectively in the base station, the cleaning system can simultaneously establish relatively independent charging paths for the first battery pack and the second battery pack on the cleaning host. This allows the system to be compatible with multiple battery usage scenarios such as host return-to-station charging and backup / replaceable battery pack charging under the same base station platform, thereby improving the system's adaptability and ease of use.

[0058] Secondly, by controlling the first and second circuits respectively in response to the first battery pack docking with the first interface and the second battery pack docking with the second interface, the charging output is matched with the charging permission / demand status of the battery pack side. This avoids blind power-on and mischarging when the battery pack is not properly docked, has not completed handshake authentication, or has not met safety conditions, thereby improving the safety, reliability and controllability of the charging process.

[0059] Furthermore, when the first preset condition and the second preset condition are met simultaneously, the control unit controls the first circuit and the second circuit to be turned on at the same time, so as to charge the first battery pack and the second battery pack at the same time. This reduces the time the user has to wait between the two charging objects, improves the charging efficiency, and enables the cleaning host to have a more stable battery life guarantee and a better user experience in long-term continuous cleaning or high-power mode.

[0060] Since the first and second battery packs can alternately power the cleaning host, this cleaning system manages the power replenishment of the two battery packs in a unified manner through the base station side. This allows users to flexibly switch between the working battery pack and the backup battery pack, reducing the probability of task interruption due to insufficient battery power, thereby enhancing the continuous operation capability and overall availability of the cleaning system.

[0061] In some exemplary embodiments of the present invention, based on the foregoing scheme, the cleaning host includes a first host and a second host; The first battery pack is detachably installed on the first host, and the second battery pack is detachably installed on the second host; and / or, the first battery pack is detachably installed on the second host, and the second battery pack is detachably installed on the first host; When the first host and the second host are respectively connected to the first interface and the second interface, the control unit controls the first circuit and the second circuit to be turned on simultaneously, so as to charge the first battery pack and the second battery pack at the same time.

[0062] By expanding the cleaning unit into a first unit and a second unit, and making the first and second battery packs detachably installed on different units, and allowing the first and second battery packs to be interchanged between the two units, the cleaning system can achieve battery resource sharing and flexible allocation in multi-unit usage scenarios, reducing cleaning task interruptions caused by insufficient power of a single unit, and improving the system's adaptability and availability to different home configurations or scenarios with multiple devices.

[0063] Secondly, it allows the first battery pack to be installed in the second host and the second battery pack to be installed in the first host, so that the battery pack and the host can form a replaceable and interchangeable power supply relationship. This allows users to flexibly select the working battery pack and the backup battery pack according to the usage frequency and battery life requirements, and realize the cyclic use of the battery pack through unified power replenishment by the base station, thereby improving the battery life guarantee capability and improving the consistency of the experience under long-term use.

[0064] In addition, when the first host and the second host are connected to the first interface and the second interface respectively, the control unit controls the first circuit and the second circuit to be turned on simultaneously, thereby realizing the parallel charging of the first battery pack and the second battery pack installed on the two hosts respectively. This reduces the waiting time for users to charge between the two hosts or frequently plug and unplug and switch, improves the energy replenishment efficiency, and thus enhances the continuous cleaning capability and overall usage efficiency in multi-host scenarios.

[0065] Therefore, this invention can achieve unified charging management and controllable status output for multiple hosts and multiple battery packs while keeping user operation simple, reducing maintenance costs caused by misconnection, mischarging or missing charging objects, thereby improving the overall reliability of the cleaning system and user experience.

[0066] In some exemplary embodiments of the present invention, based on the foregoing scheme, the control unit is configured as follows: Based on the current cleaning duration and / or return time of the cleaning host, historical cleaning interval data and / or preset cleaning plan data, a predicted time for the start of the next cleaning task is determined; before the predicted time, at least one of the first battery pack and the second battery pack is charged to the target power range.

[0067] By determining the predicted time to start the next cleaning task based on the current cleaning duration and / or return time of the cleaning host, combined with historical cleaning interval data and / or preset cleaning plan data, the base station can transform users' actual usage habits and planned needs into quantifiable time targets. This enables proactive planning of subsequent charging opportunities and avoids problems such as untimely or ineffective charging caused by relying solely on fixed times or passive triggering.

[0068] Secondly, by charging at least one of the first and second battery packs to the target power range before the predicted time, the system can ensure that at least one battery pack has the power level to start cleaning before the next cleaning task arrives, thereby reducing the probability of waiting or task interruption due to temporary power shortage and improving the endurance guarantee capability and overall availability in multi-battery rotation scenarios.

[0069] In addition, by adopting a strategy of predicting the start time and charging to the target capacity range in advance, the battery can be kept at full charge for a long time or frequently and unnecessarily recharged while meeting cleaning needs. This can reduce battery aging and energy loss caused by float charging to a certain extent, achieve a balance between charging efficiency, range guarantee and battery life, and improve the long-term reliability of the system and the consistency of user experience.

[0079] According to one aspect of the present invention, a cleaning system is provided, with reference to Figure 1 As shown, the cleaning system includes a cleaning host 20 and a base station 10. The base station 10 works in conjunction with the cleaning host 20 to charge the battery pack of the cleaning host 20 and to charge the backup battery pack. The cleaning host 20 performs cleaning operations on the surface to be cleaned. The cleaning host 20 is powered by a removable battery pack, including at least a first battery pack. The base station 10 can also interface with and charge a second battery pack. The first and second battery packs are replaceable and can be interchangeably installed on the cleaning host 20 to power it.

[0080] In some exemplary embodiments of the present invention, reference is made to Figure 2 , Figure 4 and Figure 5 As shown, the base station 10 includes a base station body 11, a charging interface 12, a charging circuit 13, and a control unit 14.

[0081] The base station body 11 is used to accommodate and install the charging interface 12, the charging circuit 13, and the control unit 14, and provides a parking and docking support structure for the cleaning host 20. In some implementations, the base station body 11 is provided with a docking position to guide the cleaning host 20 to dock with the charging interface 12 of the base station 10; the base station body 11 may also be provided with a placement position or insertion position for a spare battery pack to guide the second battery pack to dock with the charging interface 12 of the base station 10.

[0082] The charging interface 12 is disposed on the base station body 11 and includes at least a first interface 12a and a second interface 12b. The first interface 12a is used to connect with a first battery pack installed on the cleaning host 20 to form an electrical connection for a first charging path; the second interface 12b is used to connect with a second battery pack to form an electrical connection for a second charging path. The first interface 12a and the second interface 12b can adopt a contact type, pin type, or spring type electrical connection structure; to improve the reliability of the connection, a guide structure and a limiting structure can be set around the interface to ensure that the relative position of the battery pack and the interface meets the conduction requirements.

[0083] The charging circuit 13 includes a first circuit 13a and a second circuit 13b: the first circuit 13a is electrically connected to the first interface 12a and is used to output charging energy to the first battery pack; the second circuit 13b is electrically connected to the second interface 12b and is used to output charging energy to the second battery pack. In some implementations, the first circuit 13a and the second circuit 13b respectively include a switching device and a charging control device, used to realize conduction and cutoff under the control of the control unit 14, and to regulate the output current / voltage.

[0084] The control unit 14 is disposed within the base station body 11 and is used to control the conduction of the first circuit 13a and the second circuit 13b respectively. In some implementations, the control unit 14 may be a microcontroller unit (MCU) or a control board containing an MCU. The control unit 14 is electrically connected to the first circuit 13a and the second circuit 13b respectively to output enable control signals to drive the corresponding circuits into the conduction state or keep them in the off state; the control unit 14 can also obtain the status information of the battery pack to form a charging control closed loop.

[0085] In some embodiments, when the first battery pack is connected to the first interface 12a, the first circuit 13a is controlled to be turned on; When the second battery pack is connected to the second interface 12b, the control second circuit 13b is turned on; When the first battery pack and the second battery pack are connected to the first interface 12a and the second interface 12b respectively, the first circuit 13a and the second circuit 13b are activated. The connection status of the first battery pack with the first interface 12a and the second battery pack with the second interface 12b can be determined by an in-situ detection unit, interface terminal continuity detection, communication online information, or other connection detection methods. This invention does not impose specific limitations.

[0086] In this embodiment of the invention, preset conditions are used to represent a set of conditions or a determination result that allow the base station to conduct the corresponding charging circuit 13. Preset conditions can be characterized or implemented by charging enable information. For example, detecting that the first charging enable information is valid can be used to indicate that the first preset condition is met; detecting that the second charging enable information is valid can be used to indicate that the second preset condition is met. Preset conditions are not limited to being implemented by charging enable information; in other embodiments, they can also be implemented individually or in combination by conditions such as in-situ detection results, power status threshold determination, and safety threshold determination.

[0087] Based on this, the control unit 14 controls the first loop 13a and the second loop 13b in the following manner: In response to obtaining the first charging enable information corresponding to the first battery pack, the first circuit 13a is controlled to be turned on so that the first circuit 13a outputs charging power to the first battery pack through the first interface 12a; In response to obtaining the second charging enable information corresponding to the second battery pack, the second circuit 13b is controlled to be turned on so that the second circuit 13b outputs charging power to the second battery pack through the second interface 12b; In response to the simultaneous fulfillment of the first charging enable information and the second charging enable information, the first circuit 13a and the second circuit 13b are simultaneously turned on to charge the first battery pack and the second battery pack at the same time.

[0088] The first charging enable information can reflect the charging permission status or charging demand status of the first battery pack. In some implementations, the first charging enable information can be output by the first battery pack or generated by the control unit 14 based on the docking status and status data of the first battery pack. When the cleaning host 20 is parked at the docking position of the base station body 11 and docking is completed, the first interface 12a establishes an electrical connection with the first battery pack; the control unit 14 acquires the first charging enable information and, when the first charging enable information is satisfied, conducts the first circuit 13a to charge the first battery pack.

[0089] The second charging enable information can reflect the charging permission status or charging demand status of the second battery pack. In some implementations, the second charging enable information can be output by the second battery pack or generated by the control unit 14 based on the docking status and status data of the second battery pack. When the second battery pack is placed or inserted into the base station body 11 and docked with the second interface 12b, the second interface 12b establishes an electrical connection with the second battery pack; the control unit 14 acquires the second charging enable information and, when the second charging enable information is satisfied, activates the second circuit 13b to charge the second battery pack.

[0090] When both battery packs are in a charging-enabled state, the control unit 14 simultaneously activates the first circuit 13a and the second circuit 13b to charge both battery packs at the same time.

[0091] In some implementations, the first charging enable information and / or the second charging enable information may include at least one of the following: a charging request signal output by the corresponding battery pack, a confirmation signal indicating that a communication handshake with the corresponding battery pack has been completed, an in-situ detection signal indicating that the corresponding battery pack has been inserted / connected, a corresponding battery pack authentication pass signal, and an allow signal indicating that the corresponding battery pack meets a preset safety threshold.

[0092] The charging request signal can be a high / low level signal, a pulse signal, or a communication message containing a request field. In some implementations, the target battery pack's BMS can output a charging request signal after detecting that the battery level is below a threshold or receiving an interrogation command from the base station.

[0093] The communication handshake is used to confirm capability information such as battery pack model, rated voltage range, and maximum allowable charging current. After a successful handshake, control unit 14 can determine charging parameters and control the target circuit output accordingly. The confirmation signal for the communication handshake may include at least one of the following: a successful handshake response message (e.g., response_code=OK, handshake_ok=1, status=READY, etc.), a challenge-response verification pass flag (e.g., base station 10 sends a challenge, the battery pack returns a response, and control unit 14 generates an confirmation signal after verifying the signature / CRC / checksum), or a parameter negotiation complete flag (e.g., parameter negotiation complete=1).

[0094] The presence detection signal can be obtained by a position detection unit set on the base station 10. The presence detection unit can be a mechanical limit switch, a Hall sensor, a photoelectric switch, a contact short-circuit detection circuit, or an insertion identification circuit based on terminal voltage / resistance.

[0095] Authentication methods may include: whitelist matching based on the battery pack's unique identifier, challenge-response based on a key / signature, or authentication interaction based on a security chip. When authentication fails or the authentication result expires, the control unit 14 disables the target circuit and may output a prompt message or record the abnormal status.

[0096] The preset safety threshold may include at least one of the following: the battery pack temperature is within the allowable range, the terminal voltage is within the allowable range, the fault flag reported by the BMS is normal, and the terminal contact impedance is within the allowable range.

[0097] Based on this, before controlling the first circuit 13a and / or the second circuit 13b to be turned on, the control unit 14 first performs a communication handshake and / or authentication on the first battery pack and / or the second battery pack. Only when the communication handshake is successful and / or the authentication is passed will the corresponding first charging enable information and / or second charging enable information be generated, so that the power-on output of the charging circuit 13 is bound to the permission status on the battery pack side.

[0098] In some implementations, after detecting that the target battery pack has successfully docked with the target interface, the control unit 14 initiates a handshake / authentication process, as described in the following reference. Figure 3 As shown, the process may include: S301: In response to docking with the target battery pack, initialize the communication line and send a link establishment command or wake-up command; when the communication line is detected to be available, enter the handshake phase.

[0099] S302: Send a handshake request message to the target battery pack; in response to the target battery pack returning a handshake response message, verify the handshake response message.

[0100] When the handshake response message meets the preset confirmation conditions (such as correct response code, successful verification, and complete parameter fields), the communication handshake is determined to be successful, and a "handshake confirmation signal" is generated.

[0101] S303: In response to successful communication handshake and / or successful authentication, generate charging enable information corresponding to the target battery pack and set the charging enable information to a valid state; S304: In response to the charging enable information being valid, control the target circuit to be turned on in order to charge the target battery pack.

[0102] If the communication handshake fails, authentication fails, or timeout is not completed, the control unit 14 will not generate charging enable information and will keep the target loop off.

[0103] In some embodiments, the charging enable information can be obtained by combining the above-mentioned multiple signals according to a preset logic, for example: The charging enable information is valid when the in-situ detection signal is valid, the authentication pass signal is valid, and the permission signal is valid. The charging enable information is valid when both the in-situ detection signal and the communication handshake confirmation signal are valid. The charging enable information is valid when the in-situ detection signal is valid, the charging request signal is valid, and the enable signal is valid.

[0104] Based on the above combination rules, the control unit 14 turns on the corresponding charging circuit 13 when the charging enable information is valid; when any constituent signal fails, times out, or becomes invalid, the control unit 14 controls the corresponding charging circuit 13 to turn off, so as to stop charging or enter the protection state.

[0105] In some embodiments of the present invention, reference is made to Figure 4 As shown, the control unit 14 is used to implement fail-safe control for the first circuit 13a and the second circuit 13b. The control unit 14 controls the shutdown of the corresponding charging circuit 13 based on the detection results of the first charging enable information and / or the second charging enable information.

[0106] In some implementations, the control unit 14 periodically checks the validity of the first charge enable information.

[0107] In response to the absence of the first charging enable information, the control unit 14 outputs a first shutdown control signal to keep the switching device of the first circuit 13a in the off state, thereby turning off the first circuit 13a and stopping the output of charging power to the first battery pack.

[0108] Similar to the first circuit 13a, the control unit 14 periodically detects the validity of the second charging enable information.

[0109] In response to the absence of a second charging enable information, the control unit 14 outputs a second shutdown control signal to keep the second circuit 13b in a shutdown state and stop outputting charging power to the second battery pack.

[0110] The failure to detect the first charging enable information and / or the second charging enable information may include at least one of the following: the first charging enable information is absent, the first charging enable information is invalid, the first charging enable information has not been updated within a preset time window, or the first charging enable information does not meet the preset judgment conditions. To avoid misjudgment caused by plug-in / plug-out jitter, in some implementations, the control unit 14 only triggers the shutdown of the first circuit 13a when the first charging enable information is not detected for multiple consecutive sampling cycles. In other implementations, the control unit 14 may use a combination of hardware debouncing and software debouncing to avoid frequent start-stop of the charging circuit 13 due to docking transients or communication interruptions.

[0111] It should be noted that the shutdown control of the first loop 13a and the second loop 13b are independent of each other: When the first charging enable information fails while the second charging enable information remains valid, the control unit 14 controls the first circuit 13a to shut down and keeps the second circuit 13b on. When the second charging enable information fails while the first charging enable information remains valid, the control unit 14 controls the second circuit 13b to shut down and keeps the first circuit 13a on.

[0112] In this way, base station 10 can keep the corresponding circuit in a safe state when any battery pack does not meet the charging permission conditions, without affecting the normal charging of the other battery pack.

[0113] In some embodiments of the present invention, the control unit 14 is used to determine the charging termination conditions of the first battery pack and / or the second battery pack, and control the corresponding charging circuit 13 to shut down when the full charge condition is met, so as to stop charging the corresponding battery pack, thereby avoiding overcharging and improving charging safety and reliability.

[0114] In some implementations, the control unit 14 periodically acquires the terminal voltage value of the target battery pack during the charging process and compares the sampled terminal voltage with a preset full charge threshold.

[0115] The terminal voltage value can be obtained by sampling the terminal voltage of the target battery pack through the sampling circuit on the target circuit and converting it into a digital quantity; or by obtaining the voltage data reported by the battery pack through communication with the target battery pack.

[0116] To avoid misjudgment caused by transient fluctuations in voltage sampling, the control unit 14 can only perform loop shutdown after the terminal voltage continuously meets the full charge threshold and reaches a preset stable duration.

[0117] In other implementations, the target battery pack can output a full charge indication message when it detects that it is fully charged. When the control unit 14 detects that the target battery pack outputs a full charge indication message, it outputs a shutdown control signal to shut down the target circuit and stop charging the target battery pack.

[0118] Full charge indication information may be: a full charge status flag reported by the battery pack BMS via communication; and / or a level signal output by a status terminal of the target interface; and / or a status message containing a full charge field.

[0119] In some other implementations, the control unit 14 may use at least one of voltage threshold determination and full charge indication information determination as the charging termination criterion, so that in the dual-loop parallel charging scenario, each battery pack can independently exit charging according to its own state, avoiding overcharging and reducing unnecessary energy input.

[0120] In some embodiments, reference Figure 5 As shown, the first circuit 13a is equipped with a first charging controller 13a1, and the second circuit 13b is equipped with a second charging controller 13b1. The first charging controller 13a1 is used to perform constant current and constant voltage charging control on the first battery pack, and the second charging controller 13b1 is used to perform constant current and constant voltage charging control on the second battery pack. The first charging controller 13a1 and the second charging controller 13b1 can independently regulate the charging of their respective target battery packs, thereby enabling the base station 10 to stably output the corresponding charging current and charging voltage in single-circuit charging or dual-circuit parallel charging scenarios.

[0121] For example, during the constant current phase, control unit 14 is configured to perform: In response to the target circuit being turned on by the control unit 14 and starting to charge, the target charging controller is controlled to enter the constant current control stage: and the target charging controller is controlled to obtain feedback information such as the terminal voltage and charging current of the target battery pack (for example, through the sampling resistor / current detection circuit and voltage sampling circuit). The duty cycle or drive parameters of the power converter are adjusted in a closed loop based on feedback information to stabilize the charging current of the target circuit at a preset constant current value I_CC. When the terminal voltage of the target battery pack is detected to reach the preset switching threshold V_SW (e.g., close to the target constant voltage value), the target charging controller is controlled to trigger the switch from the constant current stage to the constant voltage stage.

[0122] For example, during the constant voltage stage, the target charging controller controls the charging voltage to be near the preset constant voltage value V_CV; As the battery pack gradually charges, the charging current naturally decreases. When the charging current drops to the preset termination current threshold I_END and / or the target battery pack outputs a full charge indication message, the control unit 14 controls the target circuit to shut down or controls the target charging controller to stop outputting, so as to end the charging process.

[0123] In some embodiments, when the first circuit 13a and the second circuit 13b are simultaneously turned on: The first charging controller 13a1 independently performs constant current and constant voltage control on the first battery pack, without depending on the state of the second battery pack; The second charging controller 13b1 independently performs constant current and constant voltage control on the second battery pack, without depending on the state of the first battery pack. When any battery pack needs to be derated or prematurely terminated due to temperature, internal resistance, or state of charge, only the charging controller of the corresponding circuit adjusts the control parameters or stops charging, while the other circuit can continue charging according to its target strategy.

[0124] In this way, base station 10 can achieve stable charging curves for the two battery packs even when there are differences (such as different remaining power, health status, and temperature status), thus avoiding charging instability caused by mutual interference during parallel charging.

[0125] In some embodiments of the present invention, in addition to having a charging function, the base station 10 also integrates a dust collection component, which is used to transfer the dust in the dust box / dust bin of the cleaning host 20 to the collection structure on the base station 10 side after the cleaning host 20 returns to the station. The control unit 14 is used to coordinate the dust collection process and the charging process, so that the dust collection and charging are executed according to a preset timing sequence.

[0126] In some implementations, the base station body 11 is provided with a docking position to guide the cleaning host 20 to park and dock with the base station 10. The control unit 14 is configured to perform the following steps: In response to the docking of the cleaning host 20 with the base station body 11, the dust collection component is controlled to perform a dust collection operation; In response to the completion of the dust collection operation and the detection of the first charging enable information, the first circuit 13a is controlled to be turned on.

[0127] The control unit 14 can determine that the cleaning host 20 has been properly docked with the base station body 11 by using a docking detection signal. The docking detection signal can come from a docking switch, position sensor, interface terminal continuity detection, or communication online information, etc. The dust collection assembly may include dust collection drive components (such as fans / motors), dust collection pipelines, dust bags / dust bins, etc. The control unit 14 can control the dust collection drive components to start during dust collection operation and maintain the preset dust collection time or maintain it until the dust collection end conditions are met.

[0128] The completion of the dust collection operation can be determined by at least one of the following methods: The dust collection duration reaches the preset dust collection time, the dust collection motor current / negative pressure change is detected to meet the preset stability condition, the dust collection host 20 dust bin / dust box status signal is detected to indicate that dust discharge has been completed, and the working status of the dust collection component is detected to have reached the preset end state.

[0129] In some implementations, in response to the completion of the dust collection operation, the control unit 14 may also control the dust collection drive to stop or enter a low-power state and set the dust collection process to a completed state.

[0130] In some embodiments of the present invention, in addition to the base station body 11, charging interface 12, first circuit 13a, second circuit 13b, and control unit 14, the base station also includes a delay circuit (not shown). The delay circuit is electrically connected to the control unit 14 and is used to provide a preset delay window after the dust collection operation is completed, so that the conduction of the charging circuit 13 occurs in a more stable system state.

[0131] The delay circuit can be implemented using any one of the following or a combination thereof: Hardware timing circuits: for example, RC charging and discharging networks combined with comparators / Schmitt triggers to form delayed outputs; Timing chip circuits: such as monostable trigger circuits or dedicated delay devices that output delayed arrival signals; Programmable delay circuits: such as delay timing circuits implemented by counters / dividers, whose delay time is configured by the control unit; Isolation / Shaping Unit: Used to shape, de-jitter, or isolate the end edge to improve the stability of end edge detection.

[0132] The delay circuit can output a "delay arrival signal" or a "timing completion signal" to the control unit, which then decides whether to activate the first or second circuit based on the signal.

[0133] In some embodiments, the control unit outputs a dust collection drive signal to control the dust collection assembly to perform dust collection operations. The dust collection assembly may include a dust collection drive component (e.g., a motor / fan), a dust collection channel, and a dust bag, etc.

[0134] During dust collection operation, control unit 14 maintains the dust collection drive signal in a first state (e.g., high level, active PWM, or enabled state) to drive the dust collection drive device. When the dust collection operation ends, control unit switches the dust collection drive signal to a second state (e.g., low level, inactive PWM, or disabled state). The "end edge of the dust collection drive signal" can be the edge that switches from the first state to the second state (e.g., falling edge), or it can be the switching event where the dust collection drive signal changes from an active state to an inactive state.

[0135] In some embodiments, the control unit 14 controls the delay circuit and the charging circuit 13 according to the following logic: In response to the detection that the cleaning host is connected to the base station body, a dust collection drive signal is output to control the dust collection component to perform a dust collection operation; In response to the completion of the dust collection operation, the dust collection drive signal is disabled; and in response to the end edge of the dust collection drive signal, the delay circuit is triggered to start timing. When the delay circuit reaches the preset delay time, the delay circuit outputs a delay arrival signal; In response to a delayed arrival signal, control the first circuit 13a or the second circuit 13b to conduct in order to charge the battery pack connected to the corresponding interface.

[0136] In some embodiments of the present invention, the dust collection assembly includes a dust bag for collecting dust transferred by the self-cleaning host 20. To ensure the sealing and reliability of the dust collection process, the control unit 14 performs a pre-verification of the dust bag's installation status and dust fullness before initiating the dust collection operation, and only allows the dust collection operation to be performed when the dust bag is installed in place and is not in a dust full state.

[0137] In some implementations, the base station body 11 is equipped with a dust bag installation detection unit to detect whether the dust bag is installed in place. The dust bag installation detection unit can be a mechanical limit switch, a magnetic induction switch, a photoelectric switch, or a contact continuity detection structure, etc.

[0138] In some implementations, the base station body 11 is equipped with a dust fullness detection unit to detect whether the dust bag is full. The dust fullness detection unit may be a pressure / negative pressure switch, an airflow sensor, an optical dust level detector, a weight detection structure, or a judgment logic based on changes in motor current / negative pressure.

[0139] In some implementations, if the control unit 14 does not detect that the dust bag is installed in place, or detects that the dust bag is full, the control unit 14 will prevent the dust collection drive from starting and may output a prompt message to remind the user to install the dust bag or replace / clean the dust bag.

[0140] In some exemplary embodiments of the present invention, reference is made to Figure 1 , Figure 2 and Figure 6As shown, at least one indicator light 15 is provided on the base station body 11. The control unit 14 can control the indicator light 15 to display different indication effects according to the conduction status of the first circuit 13a and / or the second circuit 13b, so as to intuitively feed back the current charging status to the user, making it easy for the user to quickly determine whether the base station 10 is charging the first battery pack, charging the second battery pack, or in a dual-circuit simultaneous charging state.

[0141] Indicator lights 15 can be located on the outer surface of the base station body 11 or on the operation panel. The control unit 14 is electrically connected to the indicator lights 15 via a drive circuit. Indicator lights 15 can be single-color, dual-color, or multi-color; multiple indicator lights 15 can also be combined to form different display modes. The control unit 14 can achieve different indication effects by controlling the on / off state of different colors, flashing frequency, duty cycle, or brightness level.

[0142] In some embodiments, the control unit 14 controls the indicator light 15 to display the indication effect according to the following correspondence: When the first circuit 13a is turned on, the indicator light 15 displays a first indication effect to indicate that the base station 10 is charging the first battery pack. The first indication effect can be a first color that is constantly on, a first flashing mode, etc.

[0143] When the second circuit 13b is activated, indicator light 15 displays a second indication effect to indicate that base station 10 is charging the second battery pack. The second indication effect can be a second color constant light, a second flashing mode, etc.

[0144] In response to the simultaneous conduction of the first circuit 13a and the second circuit 13b, the control indicator 15 displays a third indication effect to indicate that the base station 10 is in a dual-circuit parallel charging state. The third indication effect may be a combination of two colors lit simultaneously, two colors flashing alternately, or a brightness / flash frequency different from the aforementioned first and second indication effects.

[0145] In some embodiments, the control unit 14 refreshes the indicator light 15 status when the conduction state of the first circuit 13a and the second circuit 13b changes. For example, when switching from single-circuit charging to dual-circuit simultaneous charging, the control unit 14 switches the indicator effect to a third indicator effect; when either circuit is turned off, the control unit 14 switches the indicator effect back to the corresponding single-circuit conduction indicator effect or an off state. In this way, the indicator light 15 can reflect the changes in the charging operation status of the base station 10 in real time, making it easier for users to determine whether charging has started normally and whether dual charging is effective.

[0146] In some exemplary embodiments of the present invention, reference is made to Figure 1 , Figure 2 and Figure 6As shown, at least one button 16 is provided on the base station body 11 for receiving user operation commands. The control unit 14 is electrically connected to the button 16 and can collect the trigger signal of the button 16 and generate first charging enable information and / or second charging enable information accordingly. This allows the user to actively control the charging start of the first circuit 13a and the second circuit 13b through the button 16, thereby improving the controllability and interactive convenience of charging management.

[0147] Button 16 can be located on the operation panel or side wall of the base station body 11. Button 16 can be a mechanical button, a touch button, or a rotary button. The control unit 14 periodically scans the input port of button 16 to obtain operation commands such as pressing, long pressing, and double-clicking of button 16. To avoid accidental touches, in some implementations, the control unit 14 performs debouncing processing on the trigger signal of button 16 and only determines the operation command to be valid after a preset debouncing time is met.

[0148] In some embodiments, the control unit 14 generates different charging enable information based on different button 16 operation commands, examples of which include: Click operation: In response to the click operation of button 16, control unit 14 generates first charging enable information, so that the first circuit 13a has the conditions to be turned on to charge the first battery pack. Double-click operation: In response to the double-click operation of button 16, control unit 14 generates second charging enable information, enabling the second circuit 13b to be turned on to charge the second battery pack; Long press operation: In response to the long press operation of button 16, control unit 14 simultaneously generates first charging enable information and second charging enable information, so that the first circuit 13a and the second circuit 13b have the conditions to be simultaneously turned on to enter the dual-circuit charging mode. Re-trigger: In response to triggering the same operation command again, the control unit 14 cancels the corresponding charging enable information or sets it to an invalid state to exit the corresponding charging mode.

[0149] In some exemplary embodiments of the present invention, the control unit 14 of the base station 10 is used to monitor the power status of the first battery pack and the second battery pack, and automatically generate first charging enable information and / or second charging enable information based on the power status information, so as to realize on-demand power replenishment and automated charging management of the two battery packs.

[0150] In some implementations, the control unit 14 acquires first state-of-charge information of the first battery pack and second state-of-charge information of the second battery pack. The state-of-charge information may include at least one of the following: state of charge (SOC), battery terminal voltage, remaining capacity, remaining usable time, or charge level identifier.

[0151] Battery status information can be obtained in the following ways: The control unit 14 reads the data reported by the battery pack BMS by communicating with the battery pack, the control unit 14 estimates the battery pack terminal voltage / current by sampling and combining it with a preset mapping relationship, or the control unit 14 reads the battery pack output power level signal.

[0152] In some implementations, the control unit 14 updates the power status information of the two battery packs at preset intervals and stores the update results in a cache for threshold determination and charging strategy control.

[0153] In some exemplary embodiments of the present invention, the control unit 14 sets a first preset threshold and a second preset threshold to determine whether the corresponding battery pack needs to enter a charging state. The threshold can be a SOC threshold, a terminal voltage threshold, or a remaining capacity threshold, etc., and the threshold value can be preset according to battery specifications or product strategy.

[0154] Control unit 14 is configured as follows: In response to the first power status information indicating that the power of the first battery pack is lower than the first preset threshold, the control unit 14 generates the first charging enable information and sets the first charging enable information to an active state, so as to allow the subsequent conduction of the first circuit 13a to charge the first battery pack.

[0155] In response to the second power status information indicating that the power of the second battery pack is lower than the second preset threshold, the control unit 14 generates the second charging enable information and sets the second charging enable information to an active state to allow the subsequent conduction of the second circuit 13b to charge the second battery pack.

[0156] The first charging enable information and the second charging enable information can be generated independently: when the power of either battery pack is lower than the corresponding threshold, only the corresponding charging enable information is generated; when both battery packs are lower than the corresponding threshold, the first charging enable information and the second charging enable information are generated simultaneously, thus providing conditions for the simultaneous conduction of the dual circuits.

[0157] In this way, base station 10 can automatically trigger charging permission based on the actual power demand of the two battery packs, reducing user intervention and missed charging situations, and improving the battery life guarantee capability and ease of use in dual battery switching scenarios.

[0158] In some exemplary embodiments of the present invention, reference is made to Figure 2 , Figure 4 and Figure 5As shown, the base station body 11 is equipped with a first presence detection unit 111 and a second presence detection unit 112, which are used to detect the presence status of the first battery pack and the first interface 12a, and the presence status of the second battery pack and the second interface 12b, respectively. The control unit 14 sets conduction access conditions for the first circuit 13a and the second circuit 13b based on the presence detection results, so that the charging output is bound to the actual connection status of the battery pack, avoiding no-load output and mischarging when not inserted, not inserted properly, or poor contact.

[0159] In some implementations, the first presence detection unit 111 and / or the second presence detection unit 112 may be implemented in at least one of the following ways: Mechanical detection: A limit switch is installed near the interface. When the battery pack is inserted or docked in place, the switch is triggered to output an in-position signal. Magnetic / Hall Sensor Detection: A magnet is installed inside the battery pack, and a Hall sensor is installed on the base station 10 side. When the battery pack is in place, the Hall sensor output meets the threshold. Photoelectric detection: Detects whether the battery pack has entered the preset position using an obstruction-type photoelectric sensor; Contact continuity detection: After the battery pack is in place, the preset detection terminal is shorted or a preset resistance value is formed. The control unit 14 can determine that the battery pack is in place by sampling the corresponding level / resistance. Communication online detection: After the battery pack is connected, the communication link is online. The control unit 14 determines that it is in place if it receives an online frame / heartbeat frame within a preset time window.

[0160] Control unit 14 is configured as follows: The first circuit 13a is allowed to conduct only when the first presence detection unit 111 detects that the first battery pack is in place; The second circuit 13b is allowed to conduct only when the second presence detection unit 112 detects that the second battery pack is in place; The first circuit 13a and the second circuit 13b are allowed to be turned on simultaneously only when the first presence detection unit 111 detects that the first battery pack is in place and the second presence detection unit 112 detects that the second battery pack is in place.

[0161] Specifically, when both on-state conditions are met simultaneously and both the first charging enable information and the second charging enable information are valid, the control unit 14 controls the first circuit 13a and the second circuit 13b to be turned on simultaneously to charge the two battery packs in parallel; when either on-state signal fails, the control unit 14 only shuts down the corresponding circuit or prohibits entering the dual-circuit simultaneous conduction state to maintain the safety and stability of the charging output.

[0162] In this way, base station 10 can establish clear conduction access conditions in single-battery charging and dual-battery parallel charging scenarios, reducing no-load output, mischarging, and repeated start-stop due to unstable docking, thereby improving the reliability of the charging process and user experience.

[0163] In some exemplary embodiments of the present invention, the control unit 14 of the base station 10 is used to perform power constraint control in a parallel charging scenario where the first circuit 13a and the second circuit 13b are simultaneously turned on, so as to avoid voltage drop, overheating or charging interruption caused by the total charging power exceeding the external power supply capacity of the base station 10 or the upper limit of the system's allowed power. During parallel charging, the control unit 14 acquires the real-time charging power of the first circuit 13a and the second circuit 13b, and when the sum of the real-time charging power of the two circuits exceeds a preset total power threshold, it reduces the charging current of at least one circuit or switches to a time-sharing charging mode.

[0164] In some implementations, the control unit 14 acquires the real-time charging power of the first circuit 13a and the second circuit 13b, respectively. The real-time charging power can be obtained as follows: Control unit 14 acquires the circuit output voltage and charging current, and calculates the real-time power, wherein: Real-time power of first circuit 13a ; Real-time power of second circuit 13b ; in, These are the sampled output voltage values ​​of the first circuit 13a and the second circuit 13b. These are the sampled charging current values ​​for the first circuit 13a and the second circuit 13b.

[0165] The first charging controller 13a1 and / or the second charging controller 13b1 report the current output power or voltage and current parameters to the control unit 14, and the control unit 14 obtains the parameters accordingly. .

[0166] Control unit 14 updates at a preset sampling period And calculate the total charging power. .

[0167] Based on this, the control unit 14 will increase the total charging power. Compared with the preset total power threshold Comparison: when When, maintain the parallel charging strategy; when At that time, the power limiting action is triggered.

[0168] The preset total power threshold can be set in advance based on the external adapter specifications, the base station 10 power module capacity, or the system thermal design parameters; in some implementations, the threshold can also be dynamically adjusted according to temperature or power supply status.

[0169] In some embodiments, in response to The control unit 14 performs derating control to reduce the charging current of the first circuit 13a and / or the second circuit 13b. Examples of derating methods include: Single-path derating: Prioritize reducing the charging current of a specific path (e.g., reducing the current of the circuit corresponding to a battery pack with higher capacity) to bring the total power back below the threshold. Dual-path coordinated derating: Simultaneously reduce the charging current of two paths according to a preset ratio (e.g., according to...). (Proportional scaling) to smoothly reduce total power; Priority derating: Based on preset priorities, the charging current of one battery pack is guaranteed first, while the charging current of the other circuit is drated or suspended.

[0170] The control unit 14 can derating by setting the target current values ​​of the first charging controller 13a1 and the second charging controller 13b1, or by controlling the operating parameters of the switching devices in the control loop.

[0171] In other embodiments, in response to The control unit 14 switches to time-sharing charging mode, causing the first circuit 13a and the second circuit 13b to alternately conduct according to time slices. Examples of time-sharing charging modes include: Within the first time slice, only the first circuit 13a is turned on and the second circuit 13b is turned off; During the second time slice, only the second circuit 13b is turned on and the first circuit 13a is turned off. The on-time ratio of each circuit is dynamically adjusted according to the preset duty cycle or the difference in electrical power.

[0172] In some implementations, the control unit 14 sets a minimum on-time duration and a minimum off-time duration when switching between time-sharing charging modes to avoid device wear or interface jitter caused by frequent switching.

[0173] When detected Falling back below the preset recovery threshold (e.g., below) When the preset hysteresis is subtracted, the control unit 14 can restore parallel charging or increase the drated charging current to the target value. By setting the hysteresis threshold, frequent switching caused by power fluctuations around the threshold can be avoided.

[0174] In some exemplary embodiments of the present invention, reference is made to Figure 6As shown, the cleaning unit 20 in the cleaning system includes a first unit 20a and a second unit 20b. The first unit 20a and the second unit 20b can be the same type or different types of cleaning units 20, such as a handheld vacuum cleaner and an upright vacuum cleaner, or two handheld vacuum cleaners. To improve the power replenishment efficiency in multi-device usage scenarios, the cleaning system is equipped with a first battery pack and a second battery pack. Both battery packs are detachable and can be interchanged between the first unit 20a and the second unit 20b to power the corresponding unit.

[0175] In some implementations, the first host 20a has a first battery compartment structure, and the second host 20b has a second battery compartment structure. The first battery pack and the second battery pack each have a positioning structure and electrical connection terminals for matching battery compartments, and the external dimensions, locking structures, and terminal layouts of the first battery pack and the second battery pack meet the requirements for interchangeable assembly, thereby achieving: In one installation method, the first battery pack is detachably installed on the first host 20a, and the second battery pack is detachably installed on the second host 20b; In another installation method, the first battery pack is detachably installed on the second host 20b, and the second battery pack is detachably installed on the first host 20a.

The first interface 12a and the second interface 12b can be arranged at different docking positions on the base station body 11 to allow the first host 20a and the second host 20b to be parked and docked at the same time.

[0177] In some implementations, the base station body 11 is equipped with a first docking position and a second docking position: When the first host 20a is parked at the first docking position, the first interface 12a docks with the first battery pack installed on the first host 20a. When the second host 20b is parked in the second docking position, the second interface 12b docks with the second battery pack installed on the second host 20b.

[0178] When the battery packs are interchanged, the first interface 12a can be connected to either the first or the second battery pack, and the second interface 12b can be connected to either the first or the second battery pack.

In response to the detection that the second battery pack is connected to the second interface 12b and the second battery pack meets the charging enable condition, the control unit 14 controls the second circuit 13b to be turned on to charge the second battery pack. In response to both the first battery pack and the second battery pack meeting the charging enable conditions, the control unit 14 controls the first circuit 13a and the second circuit 13b to be turned on simultaneously, so as to charge the first battery pack and the second battery pack at the same time.

[0181] In some exemplary embodiments of the present invention, the control unit 14 of the base station 10, in addition to controlling the on and off of the first circuit 13a and the second circuit 13b, is also used to predict the start time of the next cleaning task based on the usage behavior and planning information of the cleaning host 20, and to charge at least one of the first battery pack and the second battery pack to the target power range before the predicted time, so as to improve the availability and continuous operation capability of the next cleaning task.

[0182] Control unit 14 acquires at least one of the following data and uses it to generate the prediction time: Current cleaning duration Tc: The total duration of this cleaning task from start to finish; Return time Tr: The time when the cleaning host 20 is parked at the base station 10 and the docking is completed; Historical cleaning interval data ΔT hist The interval between the start times of two consecutive cleaning tasks, or the interval between returning to the station and the start of the next cleaning task; Preset cleaning plan data S plan User-defined planned cleaning times, periodic plans, or schedule information.

[0183] In some implementations, the control unit 14 records Tc and Tr on a per-cleaning-task basis and maintains the interval sequence of the most recent N cleaning tasks as ΔT. hist Preset cleaning plan data can be set by the user on the mobile device or base station 10 panel and stored in the control unit 14.

[0184] Control unit 14 is based on Tc, Tr, ΔT hist and / or S plan Generate the predicted time T for the start of the next cleaning task. next Example implementations include: Historical interval prediction: Tr is combined with the statistical value of historical cleaning intervals to obtain T. next For example, the mean, weighted mean, or median can be used as an estimate for the next interval; Based on planned time prediction: When preset cleaning plan data exists, the planned cleaning time is directly used as T. next ; Fusion forecasting: When both historical and planned data exist, the planned time should be used first, or the time T should be fine-tuned based on historical deviations around the planned time. next .

[0185] The above forecasting strategies can be selected and implemented according to product needs, and are not limited to this.

[0186] In other embodiments, the control unit 14 sets a target power range [SOC]. L SOC H This range represents the target battery level required to initiate the next cleaning task. In some implementations, the target battery range can be represented by the state of charge (SOC), battery terminal voltage, remaining capacity, or estimated available time.

[0188] Based on this, the control unit 14 performs pre-charging according to the following procedure: The response time reaches or exceeds T start The control unit 14 selects at least one of the first battery pack and the second battery pack as the target charging object, and controls the corresponding circuit to be turned on to start charging. During the charging process, the control unit 14 acquires the power status information of the target battery pack in real time; In response to the detection that the target battery pack's charge level has entered the target charge range [SOC] L SOC H The control unit 14 stops charging the target battery pack or switches to sustain mode. In T nextBefore the next cleaning task arrives, the control unit 14 ensures that at least one of the first and second battery packs reaches the target power range to meet the startup requirements of the next cleaning task.
