Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a control method, apparatus and cleaning system for a cleaning system. Background Technology

[0002] With the popularization of smart home technology, floor scrubbers have become a core device for cleaning surfaces in modern homes. Their high efficiency, combining vacuuming, mopping, and self-cleaning, greatly enhances the user's cleaning experience.

[0003] In existing technologies, floor scrubbers generally use detachable or built-in rigid-encapsulated lithium battery packs as their power source. When the device runs out of power and returns to the base station to recharge, it establishes an electrical connection with the battery pack through the base station contacts to replenish its power.

[0004] However, when the battery pack requires high-current charging due to over-discharge, it can easily cause a sharp rise in temperature. Alternatively, if the device is immediately placed at the base station for charging after cleaning, the battery pack temperature will be high. To prevent thermal runaway, the battery management system will trigger a high-temperature protection mechanism, waiting for the battery pack to cool down naturally before recharging, which severely impacts the continuity and efficiency of cleaning operations. Summary of the Invention

[0005] This application provides a control method, device, and cleaning system for a cleaning system. By designing a cleaning system with a cooling structure, a third fan, and a third air duct, the low-temperature airflow generated by the cooling structure is directionally delivered to the battery pack area through the third air duct. This allows for active cooling of the battery pack when its temperature rises, improving the heat dissipation efficiency and temperature control effect of the battery pack, thereby improving the energy consumption, continuity of operation, and stability of the cleaning system during operation.

[0006] In a first aspect, this application provides a control method for a cleaning system, the cleaning system including a cooling structure, a third fan and a third air duct, and a battery pack for a cleaning device; the cooling structure includes a cooling end, the air inlet of the third fan is opposite to the cooling end, and the air outlet of the third fan is connected to the battery pack of the cleaning device through the third air duct; the method includes:

[0007] If the temperature of the battery pack is detected to be higher than the preset temperature threshold, the cooling structure is activated and the third fan is activated to deliver the cooling energy generated by the cooling end to the battery pack through the third air duct.

[0008] Compared with the problem in the prior art that the battery pack is prone to affect the battery life, stability and operating efficiency due to excessive temperature rise during continuous operation and high-power operation of the cleaning device, in this application, when it is detected that the temperature of the battery pack is greater than the preset temperature threshold, the battery pack cannot operate normally. At this time, the cleaning system switches to the active battery cooling state, the refrigeration structure starts to generate cold at the refrigeration end, the third fan starts to establish a directional air flow from the refrigeration end to the battery pack, and the third air duct serves as the cold quantity transmission path, so that the cold air acts on the battery pack to achieve the temperature reduction treatment of the battery pack. In this way, for the heat generated by the battery pack during the operation of the cleaning device or under high-load conditions, it can be timely dissipated through the above-mentioned linkage control, and the temperature of the battery pack will not continuously maintain in the super-threshold state, but maintain the operating temperature of the battery pack within the set range.

[0009] Therefore, in this application, by constructing the refrigeration end of the refrigeration structure, the air inlet of the third fan and the third air duct connecting the battery pack into a continuous cold quantity transmission link, and performing the linkage start control of the refrigeration structure and the third fan when the temperature of the battery pack exceeds the preset temperature threshold, the cold quantity can be directed to the surrounding area of the battery pack, thereby forming an active cooling process for the battery pack. Thus, it is possible to actively cool the battery pack when its temperature rises, improve the heat dissipation efficiency and temperature control effect of the battery pack, and further improve the energy consumption performance, battery life and operating stability during the continuous operation of the cleaning device.

[0010] Optionally, the cleaning system further includes a liquid collector, a water tank and a power device. The liquid collector is at least used to collect the condensed water generated at the refrigeration end, and the power device is used to pump the condensed water collected in the liquid collector into the water tank; the method further includes:

[0011] During the start-up process of the third fan, control the power device to be turned off.

[0012] Since the time for the battery pack to cool down is short, during the start-up period of the third fan, the water pumping action for the condensed water can be stopped, so that the condensed water can be stably retained in the liquid collector and pumped into the water tank for recovery after the power device is started in the subsequent period.

[0013] In this way, turning off the power device when the third fan starts can avoid the interference of the water pumping action on the cooling process and affect the cooling effect of the third fan on the battery pack. Turning off the power device can ensure the stability and efficiency of the cooling process. After turning off the power device, the condensed water can be stably retained in the liquid collector without being disturbed by suction, avoiding incomplete collection or liquid level fluctuation caused by continuous water pumping, so that the recovery of the condensed water is more stable.

[0014] Furthermore, battery pack cooling is a short-term task, and suspending the power unit during this period reduces unnecessary power consumption and improves the overall energy efficiency of the cleaning system. Moreover, by delaying water collection until after cooling is complete, the battery pack cooling and power unit water collection processes can be staggered, preventing them from conflicting and making the cleaning system operate more systematically.

[0015] Optionally, the method also includes:

[0016] If the temperature of the battery pack is detected to be less than or equal to a preset temperature threshold, or if the start-up time of the third fan is detected to be longer than a preset cooling time, the third fan will be shut down.

[0017] When the battery pack temperature drops below the preset temperature threshold, the cooling objective has been achieved. Turning off the third fan promptly prevents overcooling and energy waste. Turning off the third fan when the startup time exceeds the preset cooling time prevents it from running indefinitely, thus providing safety protection.

[0018] In this way, the above control method, by controlling the third fan to shut down in a timely manner when the temperature drop condition is met or the upper limit of the cooling time is reached, can form a closed-loop cooling control in conjunction with the aforementioned start-up control, thereby matching the cooling output with the actual heat dissipation requirements of the battery pack. This allows the third fan to maintain airflow only when necessary and to stop working after cooling is complete, thus reducing ineffective operating time and maintaining the battery pack temperature within the target range.

[0019] Optionally, the method also includes:

[0020] With the third fan off, the control unit is turned on to pump the condensate collected in the unit into the water tank.

[0021] Therefore, this application sets up a system where the operation of the condensate pumping process to the water tank is staggered from the operation of the third fan. This ensures that the power unit only performs the pumping action after the third fan is turned off, thereby making the liquid delivery process more stable and allowing the condensate to enter the water tank for collection in a timely manner. As a result, interference between the condensate recovery process and the refrigeration air supply process is reduced, and the operating status of the power unit is easier to control, thus improving the reliability of condensate recovery and the consistency of the cleaning system's operation.

[0022] Optionally, the cleaning system also includes cleaning equipment and a cleaning base station, which, upon detecting that the battery pack temperature exceeds a preset temperature threshold, controls the activation of a cooling structure, including:

[0023] When the cleaning equipment is detected to be placed at the cleaning base station and the temperature of the battery pack is greater than the preset temperature threshold, the cooling structure is activated.

[0024] Therefore, this application sets the cold energy delivery to be performed only when the cleaning equipment is located at the cleaning base station and links it to the temperature status of the battery pack, thereby matching the thermal management process with the in-situ status of the cleaning equipment.

[0025] In addition, since the cooling capacity is output when the cleaning equipment is parked at the cleaning base station, the cleaning system can complete the cooling of the battery pack in a relatively stable state and work in conjunction with the standby, recharging or self-maintenance process of the cleaning equipment, so that the temperature of the battery pack drops more promptly, the control consistency of battery thermal management is higher, and the battery is prevented from entering the "false charging" protection state due to heat (located on the cleaning base station, but not actually charged).

[0026] Optionally, the refrigeration structure also includes a heating end disposed opposite to the refrigeration end, and the method further includes:

[0027] When the refrigeration structure is activated, the temperature information of the refrigeration end and the heating end are obtained respectively;

[0028] When a temperature difference is determined between the cooling and heating ends based on temperature information, the output voltage of the cooling structure is determined based on the temperature difference, and a drive current is generated based on the output voltage.

[0029] In this way, this application achieves direct energy conversion and adaptive power supply based on temperature difference by separately collecting the temperatures of the cooling and heating ends and adjusting the output voltage according to the temperature difference. The output voltage is then converted into driving current, thereby improving the energy utilization efficiency and power supply control accuracy of the cleaning system. Furthermore, by converting temperature difference changes into electrical energy output, the power supply control of the refrigeration structure is linked to the states of its cooling and heating ends. This not only reduces energy loss in intermediate energy conversion stages but also ensures a stable cooling output for the cleaning system.

[0030] Optionally, the method also includes:

[0031] During the self-cleaning process of the cleaning system or during the cleaning of the surface to be cleaned, the cleaning equipment is powered by the drive current.

[0032] Therefore, by using the drive current to power or supplement the cleaning equipment during the self-cleaning or cleaning process of the cleaning system, the cleaning equipment can maintain simple operation without relying on external power supply, thereby keeping the self-cleaning process and cleaning operation continuous, thus improving the power supply stability and operation consistency of the cleaning system in working condition.

[0033] Optionally, the cleaning system further includes a first fan, and the cooling structure further includes a heating end disposed opposite to the cooling end, with the air inlet of the first fan facing the heating end. The method further includes:

[0034] The first fan is activated to dissipate the heat generated at the heating end.

[0035] In this way, the above structural design creates an independent heat dissipation path between the heating end and the cooling end. By controlling the start of the first fan, the heat generated by the heating end can be dissipated in a timely manner, thereby reducing the impact of heat accumulation on the operation of the cooling structure and enabling the cleaning system to maintain a relatively stable thermal management state under continuous operation or high load conditions.

[0036] Optionally, the cleaning system includes cleaning equipment and a cleaning base station. The cleaning base station includes a first air duct and a roller brush cleaning tank. The cleaning equipment includes a floor brush assembly, which includes a roller brush. The roller brush cleaning tank is used to accommodate the roller brush. One end of the first air duct is connected to the air outlet of a first fan, and the other end is connected to the roller brush cleaning tank. The system controls the first fan to start, so as to dissipate the heat generated by the heating end, including:

[0037] During the self-cleaning process of the cleaning system, the first fan is activated to transfer the heat generated by the heating end to the roller brush cleaning tank through the first air duct to dry the roller brush.

[0038] In this way, by introducing the heat generated at the heating end into the roller brush cleaning tank during the self-cleaning stage, the roller brush is simultaneously dried after cleaning, thereby shortening the time for the roller brush to return to a usable state and reducing the amount of residual moisture remaining on the bristles and the surface of the roller brush substrate. Since the heat is directionally transported through the first air duct, the hot air effect is concentrated within the roller brush cleaning tank, which can improve the efficiency of waste heat utilization and enhance the uniformity of roller brush drying.

[0039] Optionally, the cleaning system also includes a first heating element located within a first air duct. The self-cleaning process includes a drying stage. During the self-cleaning process, a first fan is activated to transfer the heat generated at the heating end to the roller brush cleaning tank through the first air duct.

[0040] In the self-cleaning process, when the cleaning system is detected to have entered the drying stage, the cooling structure is shut down, and the first air duct and the first heating element are activated to heat the airflow from the first air duct to the roller brush cleaning tank.

[0041] Therefore, after the drying stage of the cleaning system, by reusing the structure of the first fan and controlling the shutdown of the cooling structure while activating the first fan and the first heating element, the airflow entering the roller brush cleaning tank can be directly reheated even with the cooling structure shut off. This allows the airflow to be continuously heated during transport and then applied to the surface of the roller brush within the cleaning tank, creating a stable hot air drying environment. This enables the drying and cooling processes to switch between each other without functional conflicts, thereby improving the removal efficiency of residual moisture in the roller brush cleaning tank and enhancing the drying effectiveness of the cleaning system.

[0042] Optionally, the cleaning system includes cleaning equipment and a first air duct. A cooling structure is installed on the cleaning equipment. One end of the first air duct is connected to the air outlet of a first fan, and the other end is connected to the outside. The system controls the first fan to start, dissipating the heat generated at the heating end, including:

[0043] During the cleaning process, the first fan is activated to deliver the heat generated by the heating end to the surface to be cleaned through the first air duct, thereby drying the moisture on the surface.

[0044] Because one end of the first air duct is connected to the air outlet of the first fan, and the other end faces downwards from the surface to be cleaned or is connected to the outside, heat is applied to the damp area after cleaning. This control method allows the heat from the heating element to be directly utilized during the cleaning process and links the hot air output with the cleaning task.

[0045] Through the above structural design, the heat generated by the cooling structure during operation is no longer solely used for heat dissipation, but is instead guided through the first air duct to the surface to be cleaned, creating a hot air drying effect. This allows for the timely evaporation of moisture from the surface while the cleaning task is being performed, shortening the residence time of residual moisture and enabling the cleaning equipment to have simultaneous drying capabilities in continuous wet cleaning scenarios.

[0046] Optionally, the cleaning system also includes a second fan, a second air duct, a second heating element, and a roller brush cleaning tank for the cleaning base station. The second heating element is installed inside the second air duct, one end of which is connected to the air outlet of the second fan, and the other end is connected to the roller brush cleaning tank. The airflow generated by the second fan is delivered to the roller brush cleaning tank through the second air duct. The method further includes:

[0047] During the self-cleaning process of the cleaning system, when the system is detected to have entered the drying stage, the second heating element is activated to heat the airflow from the second air duct to the roller brush cleaning tank.

[0048] Therefore, by activating the second fan and the second heating element in conjunction with each other during the drying stage, the second fan, the second air duct, and the second heating element can form a directional hot air delivery path during the self-cleaning drying stage, so that the heat is concentrated on the roller brush area in the roller brush cleaning tank. Furthermore, the residual moisture on the roller brush can be removed more quickly, and the hot and humid air in the roller brush cleaning tank can also be replaced and circulated in a timely manner, thereby improving the drying response speed and enhancing the drying uniformity.

[0049] In addition, since the heating position of the second heating element is located inside the air duct, the heat can directly enter the target area with the airflow, which can reduce heat loss and make the drying effect in the roller brush cleaning tank more stable.

[0050] Optionally, the method also includes:

[0051] Collect the ambient temperature of the cleaning system;

[0052] The output power of the cooling structure is adjusted based on the ambient temperature.

[0053] Based on the above analysis, by using ambient temperature as the basis for adjusting the power of the refrigeration structure, the refrigeration structure can dynamically adjust its output power according to changes in the ambient heat load. This enhances the cooling response in high-temperature environments and reduces ineffective energy consumption in low-temperature environments, thus ensuring that the battery pack cooling process remains consistent with the external environmental conditions and improving the stability and energy efficiency of the refrigeration control. Furthermore, since the output power can be adjusted according to changes in environmental parameters, the flexibility of the refrigeration control can also be improved.

[0054] Secondly, this application provides a control device for a cleaning system. The cleaning system includes a cooling structure, a third fan, a third air duct, and a battery pack for the cleaning equipment. The cooling structure includes a cooling end, the air inlet of the third fan is opposite to the cooling end, and the air outlet of the third fan is connected to the battery pack of the cleaning equipment through the third air duct. The device includes:

[0055] The control module is used to control the cooling structure to start and the third fan to start when the temperature of the battery pack is detected to be greater than the preset temperature threshold, so as to deliver the cold energy generated by the cooling end to the battery pack through the third air duct.

[0056] Thirdly, this application provides a cleaning system, which includes a cooling structure, a third fan and a third air duct, and a battery pack for the cleaning device; the cooling structure includes a cooling end, the air inlet of the third fan is opposite to the cooling end, and the air outlet of the third fan is connected to the battery pack of the cleaning device through the third air duct.

[0057] The cleaning system is used to perform the methods described above.

[0058] It should be noted that the second and third aspects of this application have similar beneficial effects to the corresponding technical solutions in the first aspect of this application, and the corresponding feasible implementation methods will not be repeated here.

[0059] The control method, apparatus, and cleaning system provided in this application utilize a third fan that works in conjunction with the cooling end of a cooling structure and a third air duct connected to the battery pack. When the battery pack temperature exceeds a preset temperature threshold, the cooling structure and the third fan are activated to deliver the cooling energy generated by the cooling end to the battery pack through the third air duct, thus forming an active cooling process for the battery pack. Based on the aforementioned structural design, this application's solution, through over-temperature detection triggering the coordinated action of the cooling mechanism and the third fan, suppresses battery pack temperature rise, improves battery pack heat dissipation and cooling efficiency, alleviates heat accumulation, and reduces the risk of overheating-induced charging / discharging limitations and operational interruptions, thereby improving the stability, battery life, and user experience of the cleaning system.

[0069] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0070] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0071] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, "first fan" and "second fan" are merely used to distinguish different fans and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0072] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0073] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0074] In existing technologies, floor scrubbers generally use detachable or built-in rigid-encapsulated lithium battery packs as their power source. When the device runs out of power and returns to the base station to recharge, it establishes an electrical connection with the battery pack through the base station contacts to replenish its power.

[0075] However, when the battery pack requires high-current charging due to over-discharge, it can easily cause a sharp rise in temperature. Alternatively, if the device is immediately placed at the base station for charging after cleaning, the battery pack temperature will be high. To prevent thermal runaway, the battery management system will trigger a high-temperature protection mechanism, waiting for the battery pack to cool down naturally before recharging, which severely impacts the continuity and efficiency of cleaning operations.

[0076] It should also be noted that existing technologies for battery thermal management typically employ natural heat dissipation or ordinary air-cooling structures, using the casing for heat dissipation, ventilation openings for air exchange, or conventional fans to blow air away the heat generated during battery operation.

[0077] However, the above methods have limited cooling capacity for battery packs. Especially in high humidity environments, continuous cleaning, or high-power operation, heat accumulates quickly inside the battery pack. Conventional air cooling can only deliver ambient air and cannot achieve targeted and effective cooling, which can easily lead to the battery temperature remaining at a high level.

[0078] In addition, in some cases, the battery pack may experience over-discharge due to prolonged use, causing the battery to enter a "false charging" protection state due to heat, thus preventing the battery from charging.

[0079] Thus, excessively high battery pack temperatures not only affect charging and discharging efficiency and battery life, but may also trigger protection mechanisms, leading to limited charging, operational interruptions, or decreased stability, thereby reducing cleaning efficiency and user experience.

[0080] To address the aforementioned problems, this application provides a control method for a cleaning system. By incorporating a third fan that works in conjunction with the cooling unit of a cooling structure and a third air duct connected to the battery pack within the cleaning system, when the battery pack temperature exceeds a preset temperature threshold, the cooling structure and the third fan are activated. This allows the cooling energy generated by the cooling unit to be delivered to the battery pack through the third air duct, thus forming an active cooling process for the battery pack. Based on the aforementioned structural design, this application's solution, through over-temperature detection triggering the coordinated action of the cooling mechanism and the third fan, suppresses battery pack temperature rise, improves battery pack heat dissipation and cooling efficiency, alleviates heat accumulation, and reduces the risk of overheating-induced charging / discharging limitations and operational interruptions. This, in turn, enhances the stability, battery life, and user experience of the cleaning system.

[0081] It should be noted that the control method for the cleaning system provided in this application is applied to a cleaning system, for example, Figure 1 This is a partial structural diagram of a cleaning system provided in an embodiment of this application, as shown below. Figure 1As shown, the cleaning system 300 includes a cooling structure 120, a third fan 102, a third air duct 160, and a battery pack 201 of the cleaning device 200; the cooling structure 120 includes a cooling end 121, the air inlet of the third fan 102 is opposite to the cooling end 121, and the air outlet of the third fan 102 is connected to the battery pack 201 of the cleaning device 200 through the third air duct 160.

[0082] The battery pack 201 is installed inside the cleaning equipment 200 and serves as the power supply for the entire machine. Optionally, the battery pack 201 may be equipped with a temperature detection component to output a temperature signal characterizing the current thermal state of the battery pack 201.

[0083] The cooling structure 120 is an actuator that generates cooling capacity, including at least a cooling end 121, which is used to release cooling capacity to the adjacent air medium; the third fan 102 is an air supply component that drives airflow, and its air inlet is arranged opposite to the cooling end 121 so as to draw in air that has been cooled by the cooling end 121; the third air duct 160 is an airflow delivery channel that connects the air outlet of the third fan 102 to the installation space of the battery pack 201, so that the cooling capacity can be delivered to the surface of the battery pack 201 or the area around the battery pack 201 along a predetermined path.

[0084] It should be noted that the third air duct 160 is connected to the battery pack 201, meaning it is connected to the surrounding environment of the battery pack 201. The cool air generated by the third fan 102 can be delivered to the battery pack through the third air duct 160 to dissipate heat and cool the battery pack 201.

[0085] The air inlet of the third fan 102 is arranged opposite to the cooling end 121. Specifically, the air inlet of the third fan 102 is directly opposite the cooling outlet area of ​​the cooling end 121, and an air intake path is formed between the two.

[0086] The third air duct 160 can connect the third fan 102 and the battery pack 201, so that the cold air generated by the third fan 102 can flow smoothly to the environment of the battery pack 201 under the guidance of the third air duct 160, thereby reducing the air temperature around the battery pack 201.

[0087] Optionally, the third air duct 160 can be configured as a guide channel, with the channel inlet connected to the air outlet of the third fan 102 and the channel outlet facing the surface, side wall, or interior of the battery pack 201, so that cold air reaches the area around the battery pack 201.

[0088] This can effectively improve the flow between the third fan 102 and the battery pack 201, and can effectively reduce or avoid blockages in the process of cold air reaching the battery pack 201, thereby effectively improving the smoothness of cold air to the battery pack and improving the heat dissipation and cooling effect of the battery pack 201.

[0089] Furthermore, the third air duct 160 also has a good converging effect on the path between the third fan 102 and the battery pack 201, allowing cool air to be gathered within the third air duct 160. This effectively reduces or prevents cool air from dispersing to other parts of the base 110, thus effectively reducing the loss and damage of cool air. This effectively improves the utilization rate of cool air, thereby effectively improving the heat dissipation and cooling effect on the battery pack 201.

[0090] Therefore, based on the above flow path configuration, the cooling process sequentially passes through the cooling end 121 for cooling, the third fan 102 for intake, the third fan 102 for compression, and the third air duct 160 for introduction, thus forming an active cooling path for the battery pack 201.

[0091] Optionally, the cooling structure 120 can be a semiconductor chip. When energized, the semiconductor chip exhibits the Peltier effect, allowing one end to absorb heat and form a cooling end 121. For example, a solid-state heat pump based on the Peltier effect uses direct current to drive charge carriers to transition between P-type and N-type (PN) junctions, achieving directional heat transfer. This process involves no mechanical movement, enables rapid cooling, and provides precise temperature control. Similarly, heating can also be achieved.

[0092] The temperature of the cooling end 121 can be lower than room temperature.

[0093] It should be noted that the Peltier effect can refer to the reversible characteristic of the refrigeration structure 120, which can simultaneously cool and heat. Moreover, the same refrigeration structure 120 can both cool and generate electricity using the Seebeck effect, only with opposite operating modes.

[0094] It should be noted that the cleaning system 300 includes a cleaning base station 100 and a cleaning device 200. At least some of the components of the cooling structure 120, the third fan 102 and the third air duct 160 can be installed on the cleaning base station 100 or on the cleaning device 200. This application embodiment does not specifically limit this.

[0095] For example, Figure 2 This is a schematic diagram of a clean base station provided in an embodiment of this application. Figure 3 This is a schematic diagram of the internal structure of a clean base station provided in an embodiment of this application. Figure 4 This is a cross-sectional schematic diagram of a clean base station provided in an embodiment of this application.

[0096] See Figures 2-4 The following structural descriptions are based on the example of the cooling structure 120, the third fan 102, and the third air duct 160 being installed inside the clean base station 100.

[0097] See Figure 2 As shown, the cleaning base station 100 can be used to house cleaning equipment. The cleaning equipment 200 can include a floor brush assembly and a main body. The floor brush assembly and the main body are rotatably connected; for example, the floor brush assembly can be rotatably connected to the bottom of the main body. During the cleaning process, the user can hold the main body and rotate the main body to make the floor brush assembly rotate relative to the main body, allowing the floor brush assembly to travel to different areas (e.g., under a table, under a cabinet, etc.). The floor brush assembly cleans the surface to be cleaned by contacting and rubbing against the surface.

[0098] Optionally, the floor brush assembly may include a floor brush body and a roller brush, which can be used to clean the surface to be cleaned. For example, when the cleaning device 200 is performing cleaning work, the roller brush can contact the surface to be cleaned. The roller brush is driven to rotate at high speed by a motor installed inside the roller brush, so that the roller brush can make frictional contact with the surface to be cleaned to clean the surface.

[0099] Along the direction of travel of the floor brush assembly, the roller brush can be installed at the front end of the housing, so that the roller brush can make priority contact with the surface to be cleaned. The front of the roller brush is unobstructed, which is conducive to the cleaning of the surface to be cleaned.

[0100] The cleaning device 200 may also include a clean water tank and a wastewater tank. The clean water tank holds clean water, which is then supplied to the roller brush to wet it. This allows the roller brush to soak the stains on the surface to be cleaned, reducing their adhesion and enabling the roller brush to easily wipe away the stains. At this point, the clean water mixed with the stains becomes wastewater, which is then sucked into the wastewater tank under negative pressure for centralized treatment.

[0101] Optional, such as Figure 3 and Figure 4 As shown, the cleaning system 300 also includes a liquid collector 130, a water tank, and a power unit (not shown in the figure). The liquid collector 130 is used to collect condensate generated by the cooling end 121, and the power unit is used to pump the condensate collected in the liquid collector 130 into the water tank.

[0102] It should be noted that the condensate is liquid water that has been condensed at the cooling end 121 and collected by the liquid collector 130. As the transport medium, it enters the water tank through the transport passage provided between the liquid collector 130 and the water tank. The transport passage is used to ensure that the condensate is transferred from the liquid collector 130 to the water tank.

[0103] Among them, the cooling end 121 is the working part that directly forms a low-temperature surface and comes into contact with the air to be treated, so as to cause the water vapor in the air to undergo a phase change.

[0104] Specifically, because the cooling end 121 of the refrigeration structure 120 has a low temperature, room temperature air can undergo a condensation reaction when it encounters the cooling end 121, causing condensate to be released from the air. This allows the air with high humidity to be converted into gas with lower humidity and condensate.

[0105] The liquid collector 130 is located below or near the condensate flow path of the cooling end 121, and is used at least to receive and collect condensate formed on the surface of the cooling end 121 and its adjacent area.

[0106] The power unit is an actuating component that transfers condensate from the liquid collector 130 to the water tank; for example, the power unit can be a water pump. The water tank is a liquid storage component that receives and stores condensate, and works in conjunction with the spraying, cleaning, or circulating liquid supply functions of the cleaning system 300.

[0107] It should be noted that the specific device type corresponding to the power unit is not limited in the embodiments of this application. As long as the power unit can move the condensate from the liquid collector to the water tank along the conveying path during operation, it is sufficient to realize the injection and storage of condensate.

[0108] The water pump can be installed on the cleaning base station 100. The water pump provides power for the flow of condensate towards the water tank, allowing the condensate to flow into the water tank more quickly and efficiently. This effectively accelerates the flow rate of condensate towards the water tank, effectively reducing or preventing the accumulation or aggregation of condensate in the liquid collector 130. It also prevents condensate from overflowing from the liquid collector 130 due to pressure buildup, thus effectively improving the protection of the liquid collector 130.

[0109] Optionally, the water pump can also be installed on the cleaning equipment 200. This application embodiment does not specifically limit the deployment location of the water pump.

[0110] Optionally, the clean base station 100 may also include a base 110, and a cooling structure 120 may be installed in the base 110.

[0111] Optionally, the liquid collector 130 may have a receiving cavity 131, which may be connected to a water tank. For example, the receiving cavity 131 of the liquid collector 130 may be connected to the water tank of the cleaning base station 100, or the receiving cavity 131 of the liquid collector 130 may also be connected to the clean water tank of the cleaning device 200. The receiving cavity 131 can be used to collect and contain condensate generated by the cooling end 121, so that the condensate can flow through the receiving cavity 131 to the water tank.

[0112] Specifically, because the cooling end 121 of the refrigeration structure 120 has a low temperature, room temperature air can undergo a condensation reaction when it encounters the cooling end 121, causing condensate to be released from the air. This allows the air with high humidity to be converted into gas with lower humidity and condensate.

[0113] The condensate can be collected in the receiving cavity 131 of the liquid collector 130 and then transported to the water tank. For example, the condensate in the liquid collector 130 can be directly transported to the clean water tank of the cleaning equipment 200. Alternatively, the condensate in the liquid collector 130 can be first collected in the water tank of the cleaning base station 100 and then transported to the clean water tank of the cleaning equipment 200.

[0114] This allows the refrigeration structure 120 to continuously generate condensate through the refrigeration end 121 to provide clean water to the clean water tank, eliminating the need for users to manually replenish the clean water tank. This saves users from the process of frequently adding clean water, effectively reducing the burden of housework and improving the user experience.

[0115] Furthermore, the cooling end 121 of the cooling structure 120 can convert the humidity in the air into condensate, which can effectively reduce the humidity in the air and reduce or avoid problems such as damp floors and moldy furniture caused by excessive humidity, thus effectively improving the user's health experience.

[0116] Optional, such as Figure 3 As shown, the cleaning system 300 also includes a first fan 101, and the cooling structure 120 also includes a heating end 122 disposed opposite to the cooling end 121, with the air inlet of the first fan 101 facing the heating end 122.

[0117] The other end of the cooling structure 120 can release heat to form a heating end 122. The temperature of the heating end 122 can be higher than room temperature.

[0118] The first fan 101 can dissipate heat and cool the heating end 122 of the cooling structure 120, for example, to reduce the temperature of the heating end 122, thereby reducing or avoiding the excessive temperature of the heating end 122 from affecting the normal operation of the cooling structure 120, and helping to improve the reliability and stability of the operation of the cooling structure 120.

[0119] Optional, see Figures 2-4 The cleaning base station 100 includes a first air duct 140 and a roller brush cleaning tank 111. The roller brush cleaning tank 111 is used to accommodate the roller brush. One end of the first air duct 140 is connected to the air outlet of the first fan 101, and the other end is connected to the roller brush cleaning tank 111.

[0120] The air outlet of the first fan 101 can be connected to the roller brush cleaning tank 111 to transfer the heat from the heating end 122 to the roller brush cleaning tank 111 to dry the roller brush.

[0121] The first fan 101 transfers heat from the heating element 122 to the roller brush cleaning tank 111, allowing the first fan 101 to not only dissipate heat and cool the heating element 122 but also to use the heat from the heating element 122 to dry the roller brush. This effectively improves the utilization rate of heat from the heating element 122, enhances the drying effect of the roller brush, and reduces or prevents mold growth on the roller brush due to prolonged dampness.

[0122] Furthermore, by utilizing the heating end 122 to dry the roller brush, there is no need for a separate drying device for the roller brush. This effectively simplifies the structural design of the cleaning base station 100, improves the internal space layout of the cleaning base station 100, and reduces the design difficulty and cost of the cleaning base station 100. It also effectively reduces the overall production cost of the cleaning base station 100.

[0123] Optionally, the first air duct 140 and the roller brush cleaning tank 111 can be connected by snap-fit, screw fixing, or integral molding to ensure air tightness and structural stability. The groove size of the roller brush cleaning tank 111 matches the outer diameter of the roller brush, so that the roller brush can be covered by hot air when stored. In practical applications, other models of this component can also be selected, and this application does not make specific limitations on this.

[0124] The first air duct 140 guides the hot air generated by the first fan 101, allowing it to flow smoothly to the roller brush cleaning tank 111. This effectively reduces or prevents hot air from being blown away to other areas, minimizing waste and thus improving the utilization rate of heat from the heating end 122 and enhancing the drying effect on the roller brush.

[0125] Optionally, the cleaning system 300 also includes a first heating element 150 located within the first air duct 140. The first heating element 150 can be used to heat the airflow flowing from the first air duct 140 to the roller brush cleaning tank 111.

[0126] The first heating element 150 can heat the gas in the first air duct 140, which can effectively increase the gas temperature in the first air duct 140, so that the first air duct 140 can provide hot air with higher heat to the roller brush, which can effectively increase the temperature of the roller brush and improve the drying effect of the roller brush.

[0127] The first heating element 150 and the cooling structure 120 can operate at different times. That is, when the first heating element 150 is working, the cooling structure 120 can stop working, and vice versa. Since the first heating element 150 can generate a high amount of heat, when the first heating element 150 and the cooling structure 120 are working simultaneously, the heat generated by the first heating element 150 is likely to flow to the heating end 122 of the cooling structure 120, thereby increasing the temperature of the heating end 122 and hindering its heat dissipation and cooling.

[0128] Therefore, by staggering the operation of the first heating element 150 and the cooling structure 120, damage to the cooling structure 120 caused by their simultaneous operation can be effectively reduced or avoided, which is beneficial to improving the heat dissipation protection of the cooling structure 120.

[0129] For example, when the roller brush requires high-temperature rapid drying, the first heating element 150 can be turned on to provide a higher temperature for rapid drying. When the roller brush does not require rapid drying but needs slow drying, the first heating element 150 can be turned off and the cooling structure 120 can be turned on, allowing the heating end 122 of the cooling structure 120 to slowly dry the roller brush.

[0130] Alternatively, in another possible implementation, the cleaning base station 100 may also include a second fan (not shown in the figure), the air inlet of which may be connected to the outside and the air outlet of which may be connected to the roller brush cleaning tank 111. The second fan may be used to blow air onto the roller brush to dry it.

[0131] The second fan is a wind-carrying component that provides airflow to the second air duct. After its output end is connected to the second air duct, it can stably deliver airflow into the roller brush cleaning tank 111. The second air duct is used to form a guide path from the second fan to the roller brush cleaning tank 111.

[0132] In other words, the second fan can blow room-temperature air into the roller brush cleaning tank 111 to dry the roller brush. This allows the roller brush to dry slowly under the action of room-temperature airflow, which can reduce or avoid damage to the roller brush material caused by drying at high temperatures, and helps to improve the protection against scalding of the roller brush.

[0133] Alternatively, in this example, the cleaning base station 100 may further include a second air duct and a second heating element. One end of the second air duct may be connected to the air outlet of the second fan, and the other end may be connected to the roller brush cleaning tank 111. The second heating element may be installed inside the second air duct, and the airflow generated by the second fan may be delivered to the roller brush cleaning tank 111 through the second air duct. The second heating element may be used to heat the airflow inside the second air duct to dry the roller brush.

[0134] The second heating element can be a resistance heating element, with its heating body located in the middle of the air duct or near the air outlet side, so as to uniformly heat the passing airflow. In practical applications, other models of this component can also be selected, but this application embodiment does not specifically limit this.

[0135] The second heating element can heat the airflow in the second air duct, so that the second air duct can provide high-temperature airflow to the roller brush, which can effectively increase the temperature of the roller brush and thus effectively improve the drying effect of the roller brush.

[0136] Moreover, the first air duct 140 and the second air duct are independent of each other, which can effectively prevent the high-temperature airflow generated by the second heating element in the second air duct from reaching the first air duct 140. This can prevent the high-temperature airflow from damaging the refrigeration structure 120. Under the premise of providing high-temperature drying for the roller brush, it can effectively improve the protection of the refrigeration structure 120.

[0137] In this example, the second air duct and the first air duct 140 may be merged at least at their ends so that the airflow of the second air duct and the airflow of the first air duct 140 are mixed and then jointly delivered to the roller brush cleaning tank 111.

[0138] The first air duct 140 carries hot air generated by the heating end 122 of the cooling interface, while the second air duct carries hot air generated by the second heating element. The temperature of the hot air in the first air duct 140 is relatively lower than that in the second air duct. By merging the second air duct with at least its ends of the first air duct 140, the high-temperature hot air in the second air duct can be mixed with the low-temperature hot air in the first air duct 140 before being delivered to the roller brush. This effectively improves the temperature uniformity at the roller brush, thereby enhancing the uniformity and consistency of drying the roller brush and improving the drying effect.

[0139] See also Figure 4 As shown, the clean base station 100 may also include a heat-conducting component 170, which may be located between the heating end 122 and the air inlet of the first fan 101. The heat-conducting component 170 may be used to transfer heat between the heating end 122 and the air inlet of the first fan 101.

[0140] Optionally, the cleaning system 300 may also include a temperature sensor (not shown in the figure) for collecting ambient temperature. The temperature sensor may be installed inside the housing of the cleaning base station 100, near the air intake duct, or at a detection location connected to the outside world, for real-time acquisition of the air conditions in the space where the cleaning system 300 is located.

[0141] The temperature sensor can be a digital temperature and humidity module, whose output signal can be converted into a temperature value. In practical applications, other models of temperature sensors can also be selected, but this application does not make specific limitations on this.

[0142] It should be noted that the embodiments of this application do not limit the specific types of the above-mentioned components or parts, and can refer to the description of the prior art.

[0143] For example, Figure 5 This is a schematic diagram of an application scenario provided in an embodiment of this application, such as... Figure 5 As shown, taking a home scenario as an example, the cleaning device 200 can be a floor scrubber. After the floor scrubber has completed the cleaning task on the surface to be cleaned, it is placed on the cleaning base station 100, and the temperature of the battery pack is relatively high.

[0144] In the above scenario, when it is detected that the floor scrubber is placed on the cleaning base station 100 and the temperature of the battery pack is higher than the preset temperature threshold, the cooling structure and the third fan can be activated. In this way, the cooling capacity generated by the cooling unit of the cooling structure, with the assistance of the third fan, can be converted into cool air and blown onto the battery pack.

[0145] Based on the above control method, the battery pack can be cooled down, thereby effectively reducing the temperature of the battery pack and reducing or avoiding the "false charging" situation caused by the battery overheating. In addition, it can effectively improve the overheat protection of the battery pack, thereby effectively improving the reliability and stability of the battery pack operation.

[0146] It should be noted that the control method provided in this application can be applied to cleaning systems with battery power, air duct heat dissipation, and cooling capabilities. The embodiments of this application do not limit the specific application scenarios; for example, they can be used for the continuous cleaning, self-cleaning, and recharging standby processes of cleaning equipment such as floor scrubbers in home kitchens, bathrooms, and high-humidity indoor environments.

[0147] It should also be noted that the cleaning device 200 can be a floor scrubber or any smart handheld mobile device with cleaning function. This application embodiment does not specifically limit the type of cleaning device 200.

[0148] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0149] For example, Figure 6This is a flowchart illustrating a control method for a cleaning system provided in an embodiment of this application. The control method is applied to a cleaning system that is an overall system for performing cleaning operations and implementing battery thermal management control, specifically a control unit for executing control logic. Optionally, the control unit can be a microcontroller unit (MCU) main control unit or a software logic control module.

[0150] like Figure 6 As shown, the control method of this cleaning system includes the following steps:

[0151] S601. When the temperature of the battery pack is detected to be greater than the preset temperature threshold, the cooling structure is activated.

[0152] In this embodiment, the preset temperature threshold may refer to a critical temperature standard pre-set in the battery management system to determine whether the current temperature of the battery pack deviates from the safe operating range. This embodiment does not limit the specific value corresponding to the preset temperature threshold.

[0153] Optionally, the battery pack temperature can be acquired using a temperature sensor attached to the surface of the battery pack. After acquiring the battery pack temperature, it can be further determined whether it exceeds a preset temperature threshold to decide whether to initiate cooling control.

[0154] It should be noted that when the battery pack temperature exceeds a preset temperature threshold, under specific scenarios after deep battery discharge, it is characterized as a false temperature rise signal caused by electrochemical polarization. This false temperature rise signal does not originate entirely from the heat generated by environmental heat load or external work, but rather from the change in equivalent thermal resistance caused by abnormal internal battery conditions.

[0155] Optionally, when the temperature of the battery pack is detected to be higher than a preset temperature threshold, the corresponding internal processing logic is as follows:

[0156] When the battery pack is in a state of deep discharge or over-discharge, the electrochemical balance inside the battery is disrupted, resulting in voltage imbalance of individual cells and a sharp increase in nonlinear internal impedance (internal resistance).

[0157] Under high internal resistance conditions, Joule heat and polarization heat are generated inside the battery through the release process of the weak self-discharge current or polarization voltage remaining inside the battery. Due to the change in the internal thermal capacity characteristics and heat accumulation caused by deep discharge, this heat is conducted to temperature sensing elements (such as thermistors).

[0158] Furthermore, if the temperature rise signal collected by the temperature detection element exceeds the system's set charging allowable temperature threshold (i.e., the preset temperature threshold), a charging lockout command is generated based on the determination that the battery pack temperature is greater than the preset temperature threshold. This forcibly cuts off the charging circuit to execute a thermal protection strategy until the battery pack temperature is detected to drop below the release threshold (e.g., 25°C), at which point the circuit can be reset and normal charging sequence can be resumed.

[0159] Therefore, based on the above analysis, the step of detecting that the temperature of the battery pack is greater than the preset temperature threshold specifically includes: when the battery pack is in a deep discharge state, resulting in increased internal impedance and intensified electrochemical polarization, collecting the temperature signal corresponding to the accumulated heat generated by the increased internal impedance and electrochemical polarization effect; when the temperature signal exceeds the preset temperature threshold, determining that the battery is in a state of thermal runaway risk and prohibiting the charging operation.

[0160] S602, Control the third fan to start, so as to deliver the cooling energy generated by the cooling end to the battery pack through the third air duct.

[0161] For example, the control unit of the cleaning system performs a temperature judgment after receiving the temperature of the battery pack. When the temperature of the battery pack is detected to be higher than a preset temperature threshold, the control unit generates a heat dissipation start command and outputs it to the cooling structure and the third fan.

[0162] In one possible embodiment, after the control unit detects that the battery pack temperature exceeds a preset temperature threshold, it controls the cooling structure to start, causing the cooling end to generate cooling capacity. Simultaneously, it sends a start signal to the third fan, causing the third fan to begin operation. This creates a suction effect at the third fan's inlet, drawing in low-temperature air from near the cooling end. The air is then compressed through the third fan's outlet into the third air duct and flows along the duct towards the cavity containing the battery pack, exchanging heat with the battery pack casing or the surrounding air, thereby lowering the battery pack's temperature.

[0163] In another possible embodiment, after receiving the temperature signal, the control unit can also use a conventional judgment method to determine whether to activate the cooling structure and the third fan. After the cooling structure is activated, the air temperature around the cooling end drops, and the third fan operates to draw in the low-temperature air to cool the area around the battery pack.

[0164] It should be noted that the above processing method only requires changing the core control logic that triggers the cooling structure and the third fan to start in conjunction based on the battery pack temperature exceeding the preset temperature threshold. The specific processing method is not limited in the embodiments of this application.

[0165] Optionally, if the third fan is of an adjustable speed type, its speed can be adjusted according to the temperature deviation to match to match the heat dissipation intensity. In actual applications, other types can also be selected for this component, and this application does not make any specific limitations in this regard.

[0166] Compared with the problem in the prior art that the battery pack is prone to affect the battery life, stability and usage efficiency due to excessive temperature rise during continuous operation and high-power operation of the cleaning device, in this application, when it is detected that the temperature of the battery pack is greater than the preset temperature threshold, the battery pack cannot work normally. At this time, the cleaning system switches to the active battery cooling state, the refrigeration structure starts to generate cold at the refrigeration end, the third fan starts to establish a directional air flow from the refrigeration end to the battery pack, and the third air duct serves as the cold quantity transmission path, so that the cold air acts on the battery pack to achieve the temperature reduction treatment of the battery pack. In this way, for the heat generated by the battery pack during the operation of the cleaning device or under high-load conditions, it can be timely exported through the above-mentioned linkage control. The temperature of the battery pack will not continue to maintain in the over-threshold state, but the working temperature of the battery pack is maintained within the set range.

[0167] Therefore, in this application, by constructing the refrigeration end of the refrigeration structure, the air inlet of the third fan and the third air duct connecting the battery pack into a continuous cold quantity transmission link, and executing the linkage start control of the refrigeration structure and the third fan when the temperature of the battery pack exceeds the preset temperature threshold, the cold quantity can be directed to reach the surrounding area of the battery pack, thus forming an active cooling process for the battery pack. Thus, it can actively cool the battery pack when its temperature rises, improve the heat dissipation efficiency and temperature control effect of the battery pack, and further improve the energy consumption performance, battery life and usage stability during the continuous operation of the cleaning device.

[0168] Optionally, if the refrigeration structure, the third fan, etc. are arranged on the cleaning device, when the cleaning device is cleaning the surface to be cleaned, the third fan and the refrigeration structure can also be controlled to be turned on to deliver the cold quantity generated at the refrigeration end to the battery pack.

[0169] Since the cold quantity generated at the refrigeration end can be directed by the third fan to the battery pack area, the heat of the battery pack can be taken away in time through air flow exchange. The temperature of the battery pack drops more directly, and the cold quantity utilization path is clear, which helps to maintain the stable working state of the power supply components of the cleaning device.

[0170] Optionally, the method further includes:

[0171] During the startup process of the third fan, control the power device to turn off.

[0172] It should be noted that controlling the power unit to shut down during the startup of the third fan means that the power unit is kept powered off or stopped during the operation of the third fan, so that the condensate in the liquid collector is in a static collection state. At this time, the liquid in the liquid collector will not be transported to the water tank.

[0173] For example, during the process of the cooling structure starting up and the third fan starting up, delivering the cooling energy generated by the cooling end to the battery pack through the third air duct, the control unit can output a shutdown command based on the start / stop signal of the third fan to control the power unit to shut down.

[0174] Because the battery pack cools down in a short time, the condensate pumping action can be stopped during the third fan's operation, allowing the condensate to remain stably in the liquid collector and then be pumped into the water tank for recycling after the power unit starts in a later period.

[0175] In this way, shutting off the power unit when the third fan starts avoids interference with the cooling process caused by water suction, thus preventing the third fan from affecting the cooling effect on the battery pack. Shutting off the power unit ensures a stable and efficient cooling process, and after shutting off the power unit, the condensate can remain stably in the liquid collector without being disturbed by suction, avoiding incomplete collection or liquid level fluctuations caused by continuous water suction, thereby making the condensate recovery more stable.

[0176] Furthermore, battery pack cooling is a short-term task, and suspending the power unit during this period reduces unnecessary power consumption and improves the overall energy efficiency of the cleaning system. Moreover, by delaying water collection until after cooling is complete, the battery pack cooling and power unit water collection processes can be staggered, preventing them from conflicting and making the cleaning system operate more systematically.

[0177] Optionally, the method further includes: controlling the third fan to shut down when the temperature of the battery pack is detected to be less than or equal to a preset temperature threshold or when the start-up duration of the third fan is detected to be greater than a preset cooling duration.

[0178] In this embodiment, the preset cooling time can refer to the maximum allowable duration threshold for the third fan to start and run, which is preset by the cleaning system. Its function is to serve as a judgment condition; when the actual start-up time of the third fan exceeds the preset cooling time, it is determined that the battery pack cooling process has achieved the expected cooling effect or should not be extended further, thereby triggering the control logic to shut down the third fan, preventing excessive operation of the third fan from causing energy waste or system malfunction.

[0179] Optionally, the preset cooling time can be set according to the battery pack capacity, thermal inertia, heat exchange capacity of the refrigeration structure, and workload of the cleaning system. In this embodiment, the specific duration corresponding to the preset cooling time is not limited.

[0180] For example, the control unit of the cleaning system can collect the temperature signal of the battery pack and also keep track of the cumulative start-up time of the third fan; when the temperature detection result shows that the temperature of the battery pack is no higher than the preset temperature threshold, the control unit can output a shutdown command to stop the third fan from running.

[0181] Alternatively, when the third fan is detected to have run continuously for the preset cooling time, the control unit will also output a shutdown command to end the current directional airflow.

[0182] When the battery pack temperature drops below the preset temperature threshold, the cooling objective has been achieved. Turning off the third fan promptly prevents overcooling and energy waste. Turning off the third fan when the startup time exceeds the preset cooling time prevents it from running indefinitely, thus providing safety protection.

[0183] In this way, the above control method, by controlling the third fan to shut down in a timely manner when the temperature drop condition is met or the upper limit of the cooling time is reached, can form a closed-loop cooling control in conjunction with the aforementioned start-up control, thereby matching the cooling output with the actual heat dissipation requirements of the battery pack. This allows the third fan to maintain airflow only when necessary and to stop working after cooling is complete, thus reducing ineffective operating time and maintaining the battery pack temperature within the target range.

[0184] Optionally, the method also includes:

[0185] With the third fan off, the control unit is turned on to pump the condensate collected in the unit into the water tank.

[0186] It should be noted that during the start-up process of the refrigeration structure, water vapor in the air can also be converted into condensate.

[0187] Optionally, when the third fan is off, a cooling trigger command can be generated to control the power unit to start. Optionally, the cooling trigger command can be a start signal, a communication control frame, or a start flag stored in the control register. This application embodiment does not limit the specific form of the cooling trigger command.

[0188] It should be noted that the embodiments of this application do not specifically limit the method of generating the cooling trigger command. For example, the cooling trigger command can be generated when the third fan is detected to be off and the ambient humidity is greater than the first preset humidity threshold. Alternatively, the cooling trigger command can be generated when the third fan is detected to be off and the humidity of the roller brush is greater than the second preset humidity threshold.

[0189] The first preset humidity threshold can refer to a pre-set relative humidity standard used to determine whether the current ambient air humidity has reached the threshold value for triggering the device's cooling trigger logic or cooling working mode.

[0190] The second preset humidity threshold may refer to the pre-set humidity standard of the component used to determine whether the humidity of the surface or inside of the cleaning equipment's roller brush reaches the critical value for triggering the equipment's cooling trigger logic or cooling working mode.

[0191] It is understandable that a high humidity level on the roller brush can indirectly indicate a high humidity level in the air.

[0192] It should be noted that the specific values ​​corresponding to the first preset humidity threshold and the second preset humidity threshold are not limited in the embodiments of this application, and can be set based on application scenario requirements and users.

[0193] For example, after the control unit of the cleaning equipment detects that the third fan is off, it can send an on signal to the power unit to control the power unit to turn on, so that the condensate in the liquid collector can enter the water tank through the liquid guide pipe.

[0194] Therefore, this application sets up a system where the operation of the condensate pumping process to the water tank is staggered from the operation of the third fan. This ensures that the power unit only performs the pumping action after the third fan is turned off, thereby making the liquid delivery process more stable and allowing the condensate to enter the water tank for collection in a timely manner. As a result, interference between the condensate recovery process and the refrigeration air supply process is reduced, and the operating status of the power unit is easier to control, thus improving the reliability of condensate recovery and the consistency of the cleaning system's operation.

[0195] Optionally, if the temperature of the battery pack is detected to be higher than a preset temperature threshold, the cooling structure is activated, including:

[0196] When the cleaning equipment is detected to be placed at the cleaning base station and the temperature of the battery pack is greater than the preset temperature threshold, the cooling structure is activated.

[0197] For example, after receiving the temperature of the battery pack, the control unit of the cleaning system can first determine whether the cleaning equipment has been placed at the cleaning base station. Being placed at the cleaning base station can be manifested as the cleaning equipment completing docking and positioning, charging contact contact, or communication handshake establishment with the cleaning base station.

[0198] Optionally, the cleaning equipment can be placed at the cleaning base station by means of a position detection switch, the closed state of the charging contacts, an infrared alignment signal, or a base contact signal. This application embodiment does not specifically limit this.

[0199] In this way, the control unit will only output a start command to the cooling structure when the position conditions are met and the temperature of the battery pack is greater than the preset temperature threshold, so that the cooling end can start working and generate cold energy, and the cold energy generated by the cooling end can be guided to the battery pack through the air duct.

[0200] Therefore, this application sets the cold energy delivery to be performed only when the cleaning equipment is located at the cleaning base station and links it to the temperature status of the battery pack, thereby matching the thermal management process with the in-situ status of the cleaning equipment.

[0201] In addition, since the cooling capacity is output when the cleaning equipment is parked at the cleaning base station, the cleaning system can complete the cooling of the battery pack in a relatively stable state and work in conjunction with the standby, recharging or self-maintenance process of the cleaning equipment, so that the temperature of the battery pack drops more promptly, the control consistency of battery thermal management is higher, and the battery is prevented from entering the "false charging" protection state due to heat (located on the cleaning base station, but not actually charged).

[0202] Optionally, the method also includes:

[0203] When the refrigeration structure is activated, the temperature information of the refrigeration end and the heating end are obtained respectively;

[0204] When a temperature difference is determined between the cooling and heating ends based on temperature information, the output voltage of the cooling structure is determined based on the temperature difference, and a drive current is generated based on the output voltage.

[0205] The temperature information can refer to the temperature value collected by the temperature sensor attached to the surface of the cooling end and the heating end. The temperature sensor can be a thermistor, a digital temperature sensor or a thin-film thermocouple, etc. In practical applications, other models can also be selected for this component, and this application does not make specific limitations on this.

[0206] It should be noted that in this application, since the cooling structure uses a semiconductor thermoelectric generator with thermoelectric power generation characteristics at both the hot and cold ends, the cooling end and the heating end are respectively located on opposite sides of the same device. The heating end can exchange heat with the environment through a heat sink, while the cooling end exchanges heat with the airflow on the third air duct side. Therefore, the cooling structure exhibits the Seebeck effect.

[0207] For example, taking a semiconductor thermoelectric cooler as an example, the semiconductor thermoelectric cooler has the function of "thermal power generation". Its essence is to use the Seebeck effect to directly convert the temperature difference between the cooling end and the heating end into DC voltage or current. It is a reversible thermoelectric conversion process.

[0208] Specifically, when there is a temperature difference (ΔT) between the cooling and heating ends of a thermoelectric cooler, charge carriers (electrons / holes) inside the material diffuse from the heating end to the cooling end, thus creating a potential difference (output voltage) between the two ends. A thermoelectric cooler is a "thermopile" composed of N-type and P-type semiconductors connected in series. By superimposing the thermoelectric potential, the output voltage can be increased, thereby generating electricity.

[0209] For example, the output voltage can be determined by the following formula:

[0210] V=S×ΔT

[0211] Where V represents the output voltage (mV level), S represents the Seebeck coefficient, which is determined by the material properties of the refrigeration structure; the Seebeck coefficient for semiconductors is much larger than that for metals. ΔT represents the temperature difference (K).

[0212] It should be noted that the larger ΔT is, the higher the corresponding output voltage. The output voltage can be effectively utilized in conjunction with low-power voltage conversion circuits or boost modules to generate electricity.

[0213] Specifically, the output voltage is converted into a driving current by a voltage conversion circuit. The driving current then supplies power to the downstream load or is output to the working circuit of the refrigeration structure to maintain the working state corresponding to the current temperature difference.

[0214] For example, after the cooling structure is activated, the control unit of the cleaning system synchronously reads the temperature data of the cooling end and the heating end, and calculates the temperature difference between the two ends. When the temperature difference between the two ends is greater than a preset threshold, the control unit determines the output voltage of the cooling structure based on the temperature difference using the formula mentioned above.

[0215] Optionally, electricity can be generated based on the output voltage to power low-power components such as sensors, MCUs, and indicator lights, thereby reducing energy consumption.

[0216] In this way, this application achieves direct energy conversion and adaptive power supply based on temperature difference by separately collecting the temperatures of the cooling and heating ends and adjusting the output voltage according to the temperature difference. The output voltage is then converted into driving current, thereby improving the energy utilization efficiency and power supply control accuracy of the cleaning system. Furthermore, by converting temperature difference changes into electrical energy output, the power supply control of the refrigeration structure is linked to the states of its cooling and heating ends. This not only reduces energy loss in intermediate energy conversion stages but also ensures a stable cooling output for the cleaning system.

[0217] Optionally, the method also includes:

[0218] During the self-cleaning process of the cleaning system or during the cleaning of the surface to be cleaned, the cleaning equipment is powered by the drive current.

[0219] It should be noted that since the cooling structure can be installed on both the cleaning base station and the cleaning equipment, when the cooling structure is installed on the cleaning base station, the driving current generated by the cooling structure can power the cleaning equipment during the self-cleaning process. When the cooling structure is installed on the cleaning equipment, the driving current generated by the cooling structure can also power the cleaning equipment during the cleaning process of the surface to be cleaned.

[0220] The driving current can refer to the current signal used to output operating power to the cleaning equipment. It can be generated by the refrigeration structure during thermoelectric power generation or energy conversion and transmitted to the power supply end of the cleaning equipment through the conduction line.

[0221] The self-cleaning process can refer to the working state in which the cleaning system automatically cleans and maintains the cleaning components, channels, or recycling components, and the surface to be cleaned can refer to the target surface of the cleaning equipment to be cleaned.

[0222] In some embodiments, when the cleaning system enters the self-cleaning process, it can control the power management module to connect the drive current to the power supply bus of the cleaning equipment, so that the control unit, fan and cleaning actuator can obtain working power and maintain power supply continuity during the time period required for self-cleaning.

[0223] In other embodiments, when the cleaning system performs cleaning on the surface to be cleaned, the drive current is also output to the battery pack of the cleaning equipment after voltage regulation and current shaping to replenish the battery pack with power.

[0224] Optionally, to adapt to different load conditions, rectification, voltage regulation and current limiting circuits can be set in the power supply path to adjust the amplitude of the drive current before distributing power to each power module. In practical applications, other models of power supply circuits can also be selected, and this application does not make specific limitations on this.

[0225] Therefore, by using the drive current to power or supplement the cleaning equipment during the self-cleaning or cleaning process of the cleaning system, the cleaning equipment can maintain simple operation without relying on external power supply, thereby keeping the self-cleaning process and cleaning operation continuous, thus improving the power supply stability and operation consistency of the cleaning system in working condition.

[0226] Optionally, the method also includes:

[0227] The first fan is activated to dissipate the heat generated at the heating end.

[0228] For example, after receiving the working signal of the heating end, the cooling structure entering the start-up state, or after detecting that the temperature of the heating end has reached the preset heat dissipation condition, the control unit of the cleaning system generates a start command for the first fan to start running, so that the outside air can flow through the air inlet to the area where the heating end is located, thereby carrying away the heat accumulated when the heating end is working away from the cooling structure.

[0229] Optionally, during the above process, the speed of the first fan can also be synchronously controlled to match the heating intensity of the heating end. For example, the control unit can also determine the heat dissipation demand based on the temperature value collected by the temperature sensor at the heating end. When the temperature value is detected to reach the preset upper limit, the first fan can be kept running. When the temperature value drops to the preset range, the speed of the first fan can be stopped or reduced to ensure that heat is continuously dissipated and to maintain the thermal balance of the cooling structure.

[0230] In this way, the above structural design creates an independent heat dissipation path between the heating end and the cooling end. By controlling the start of the first fan, the heat generated by the heating end can be dissipated in a timely manner, thereby reducing the impact of heat accumulation on the operation of the cooling structure and enabling the cleaning system to maintain a relatively stable thermal management state under continuous operation or high load conditions.

[0231] Optionally, the first fan is activated to dissipate heat generated at the heating end, including:

[0232] During the self-cleaning process of the cleaning system, the first fan is activated to transfer the heat generated by the heating end to the roller brush cleaning tank through the first air duct to dry the roller brush.

[0233] For example, after the cleaning system enters the self-cleaning process, the control unit can determine whether the roller brush has completed the cleaning operation based on a preset program. After determining that the cleaning operation has been completed, the control unit can control the first fan to start so that the heat generated by the heating end can be sent into the roller brush cleaning tank through the first air duct, so that the roller brush can complete the evaporation of water in the cleaning tank based on the action of hot air.

[0234] It should be noted that the self-cleaning drying stage and the semiconductor heat dissipation stage can share the same first fan.

[0235] Optionally, the cleaning base station can also control the first fan to run at a preset speed. The hot air output from the heating end continuously enters the roller brush cleaning tank along the first air duct and forms a circulating heat exchange environment in the tank. The residual moisture on the surface of the roller brush evaporates after being heated and is discharged with the airflow.

[0236] Therefore, based on the above structural design, the heat from the heating end is no longer used only for internal heat dissipation, but is guided to the area where the roller brush is located to complete directional drying, thereby achieving heat release and roller brush drying simultaneously during the self-cleaning stage.

[0237] In this way, by introducing the heat generated at the heating end into the roller brush cleaning tank during the self-cleaning stage, the roller brush is simultaneously dried after cleaning, thereby shortening the time for the roller brush to return to a usable state and reducing the amount of residual moisture remaining on the bristles and the surface of the roller brush substrate. Since the heat is directionally transported through the first air duct, the hot air effect is concentrated within the roller brush cleaning tank, which can improve the efficiency of waste heat utilization and enhance the uniformity of roller brush drying.

[0238] Optionally, the self-cleaning process includes a drying stage. During the self-cleaning process of the cleaning system, the first fan is activated to transfer the heat generated at the heating end to the roller brush cleaning tank through the first air duct, including:

[0239] In the self-cleaning process, when the cleaning system is detected to have entered the drying stage, the cooling structure is shut down, and the first air duct and the first heating element are activated to heat the airflow from the first air duct to the roller brush cleaning tank.

[0240] For example, after the cleaning system detects that the self-cleaning process has entered the drying stage, it can first send a control signal to shut down the cooling structure, then start the first fan and simultaneously drive the first heating element to work, so that the first fan continuously blows air and drives the airflow through the first heating element, so that the hot air entering the roller brush cleaning tank directly acts on the surface of the roller brush and the residual moisture in the tank.

[0241] Optionally, the heating power of the first heating element can be set according to the drying time, the moisture content of the roller brush, or the ambient temperature and humidity, so as to maintain the airflow in the tank within a temperature range suitable for drying. This application embodiment does not specifically limit this.

[0242] Therefore, after the drying stage of the cleaning system, by reusing the structure of the first fan and controlling the shutdown of the cooling structure while activating the first fan and the first heating element, the airflow entering the roller brush cleaning tank can be directly reheated even with the cooling structure shut off. This allows the airflow to be continuously heated during transport and then applied to the surface of the roller brush within the cleaning tank, creating a stable hot air drying environment. This enables the drying and cooling processes to switch between each other without functional conflicts, thereby improving the removal efficiency of residual moisture in the roller brush cleaning tank and enhancing the drying effectiveness of the cleaning system.

[0243] Optionally, the first fan is activated to dissipate heat generated at the heating end, including:

[0244] During the cleaning process, the first fan is activated to deliver the heat generated by the heating end to the surface to be cleaned through the first air duct, thereby drying the moisture on the surface.

[0245] In this step, the cooling structure is installed on the cleaning equipment. When the user uses the cleaning equipment to clean the surface to be cleaned, if the system detects that the smart floor cleaning mode is activated, the internal first air duct will automatically switch and push the heat energy of the semiconductor cooling chip directly to the surface to be cleaned through the exhaust port, thereby accelerating the removal of water stains from the surface to be cleaned.

[0246] Optionally, during the cleaning process, the cleaning system can control the first fan to be powered on and run according to the cleaning mode, the water content of the surface to be cleaned, or the duration of the task, so that the heat released by the heating end is sent to the surface to be cleaned through the first air duct. The hot airflow comes into contact with the residual water film on the surface to be cleaned and accelerates evaporation, thereby completing the drying.

[0247] Because one end of the first air duct is connected to the air outlet of the first fan, and the other end faces downwards from the surface to be cleaned or is connected to the outside, heat is applied to the damp area after cleaning. This control method allows the heat from the heating element to be directly utilized during the cleaning process and links the hot air output with the cleaning task.

[0248] Through the above structural design, the heat generated by the cooling structure during operation is no longer solely used for heat dissipation, but is instead guided through the first air duct to the surface to be cleaned, creating a hot air drying effect. This allows for the timely evaporation of moisture from the surface while the cleaning task is being performed, shortening the residence time of residual moisture and enabling the cleaning equipment to have simultaneous drying capabilities in continuous wet cleaning scenarios.

[0249] Optionally, the method also includes:

[0250] During the self-cleaning process of the cleaning system, when the system is detected to have entered the drying stage, the second heating element is activated to heat the airflow from the second air duct to the roller brush cleaning tank.

[0251] For example, during the self-cleaning process, the control unit of the cleaning equipment first determines whether the cleaning system has entered the drying stage based on the preset state. When it is confirmed that the drying stage has been entered, it outputs a heating enable signal to the second heating element and maintains the operation of the second fan, so that the external airflow passes through the heating zone through the second air duct to form hot air and is sent into the roller brush cleaning tank.

[0252] Optionally, the control unit can also adjust the output power of the second heating element according to the drying time, ambient humidity, or liquid state of the roller brush, so that the airflow temperature entering the roller brush cleaning tank is kept within a preset range, thereby completing the drying treatment of the roller brush and the residual moisture inside the tank.

[0253] Optionally, the control unit can also adjust the on / off state of the second heating element based on the temperature of the air duct or the temperature inside the tank collected by the temperature sensor, so that the heating and air supply during the drying stage are matched.

[0254] Therefore, by activating the second fan and the second heating element in conjunction with each other during the drying stage, the second fan, the second air duct, and the second heating element can form a directional hot air delivery path during the self-cleaning drying stage, so that the heat is concentrated on the roller brush area in the roller brush cleaning tank. Furthermore, the residual moisture on the roller brush can be removed more quickly, and the hot and humid air in the roller brush cleaning tank can also be replaced and circulated in a timely manner, thereby improving the drying response speed and enhancing the drying uniformity.

[0255] In addition, since the heating position of the second heating element is located inside the air duct, the heat can directly enter the target area with the airflow, which can reduce heat loss and make the drying effect in the roller brush cleaning tank more stable.

[0256] Optionally, the method also includes:

[0257] Collect the ambient temperature of the cleaning system;

[0258] The output power of the cooling structure is adjusted based on the ambient temperature.

[0259] In this embodiment, the ambient temperature can be a physical quantity representing the degree of hotness or coldness of the air in the external environment where the cleaning system is located, used to characterize the temperature value of the external space where the cleaning system is currently located.

[0260] For example, when the cleaning system is working, the control unit can collect the ambient temperature of the cleaning system, match the ambient temperature with a preset temperature range, and then output the corresponding power control signal so that the cooling structure can maintain the cooling capacity adapted to the heat dissipation requirements under different environmental conditions and stably deliver the cooling capacity to the area where the battery pack is located.

[0261] For example, when the ambient temperature is high, the control unit increases the output power of the refrigeration structure, giving the refrigeration unit a stronger cooling capacity; when the ambient temperature is low, the control unit reduces the output power of the refrigeration structure to reduce ineffective cooling. It should be noted that the aforementioned output power adjustment relationship can be pre-written into memory or continuously adjusted based on real-time detection results to maintain the refrigeration structure at an operating level that matches the environmental conditions.

[0262] In this way, the cleaning system identifies the ambient temperature and adaptively adjusts the output power of the cooling structure to achieve heat utilization at different levels. Furthermore, it can intelligently activate three dehumidification modes: sunny mode, rainy mode, and clothes drying mode.

[0263] Based on the above analysis, by using ambient temperature as the basis for adjusting the power of the refrigeration structure, the refrigeration structure can dynamically adjust its output power according to changes in the ambient heat load. This enhances the cooling response in high-temperature environments and reduces ineffective energy consumption in low-temperature environments, thus ensuring that the battery pack cooling process remains consistent with the external environmental conditions and improving the stability and energy efficiency of the refrigeration control. Furthermore, since the output power can be adjusted according to changes in environmental parameters, the flexibility of the refrigeration control can also be improved.
