Description

[0001] This application is a divisional application of the invention patent application with the application number 202411354806.0, the application date of September 27, 2024, and the invention creation name of "Self-cleaning Method, Device and Electronic Device", which was submitted to the China National Patent Office. Technical Field

[0002] This application relates to the field of cleaning equipment, and particularly to a self-cleaning method and device. Background Art

[0003] When the cleaning equipment is in the self-cleaning stage and cleaning the roller brush assembly, it usually relies on simple water flushing or mechanical scraping. These methods have limited cleaning effects on stubborn stains, such as stains like oil and soy sauce. Especially at the roots of the bristles of the roller brush assembly, due to the complex structure, it is difficult for water flushing or mechanical scraping to clean the roots thoroughly, resulting in incomplete cleaning and poor cleaning effects.

[0004] If the stains on the roller brush assembly cannot be completely removed, the remaining stains will gradually accumulate, causing the roller brush assembly to mildew, have an unpleasant smell, and even breed bacteria, which not only affects the use effect of the cleaning equipment but may also have an adverse impact on the health of the user. Summary of the Invention

[0005] This application provides a self-cleaning method, device and electronic device, which are used to solve the problems that the stains on the existing roller brush assembly cannot be completely removed, the remaining stains gradually accumulate, resulting in the roller brush assembly mildewing, having an unpleasant smell, and even breeding bacteria, affecting the use effect of the cleaning equipment, and having an adverse impact on the health of the user.

[0006] In a first aspect, this application provides a self-cleaning method, which is applied to a cleaning system. The cleaning system includes a cleaning device and a cleaning base station; the cleaning device includes a roller brush assembly, a water pump assembly, a suction motor and a scraping strip assembly; the cleaning base station includes a heating component and a cleaning cavity; the suction motor is used to provide suction force for the extraction of the liquid in the cleaning cavity; the scraping strip assembly is in interference fit with the roller brush assembly; the heating component is installed on the bottom wall of the cleaning cavity to heat the bottom liquid in the cleaning cavity; the method includes:

[0007] In response to a self-cleaning instruction, control the scraping strip assembly to move to a first position to increase the interference amount between the scraping strip assembly and the roller brush assembly, and control the roller brush assembly to rotate forward;

[0008] During the process of the cleaning device performing self-cleaning at the cleaning base station, at least when it is detected that the water pump assembly is in an on state, control the heating component to be in an on state, so that the heating component heats at least the bottom liquid in the cleaning cavity to perform thermal cleaning on the roller brush assembly.

[0009] It should be noted that in the conventional self-cleaning operation in the prior art, without the assistance of hot water, it is impossible to dissolve the oil stains on the surface and at the root of the roller brush assembly, resulting in a significant decline in the cleaning effect. Moreover, the interference fit between the existing scraping strip and the roller brush assembly remains fixed, making it impossible to adjust the interference fit between the scraping strip and the roller brush assembly according to actual cleaning needs. This design limits the extrusion force of the scraping strip on the roller brush assembly, making it difficult to remove stubborn stains at the root of the roller brush bristles and other places. Due to this unsatisfactory cleaning effect combination, it is impossible to apply a strong extrusion force to the roller brush assembly during cleaning to squeeze out the dirt at the root of the roller brush assembly, thereby reducing the cleaning effect.

[0010] Compared with the cleaning methods in the prior art, the present application can control the interference fit between the scraping strip assembly and the roller brush assembly according to the working mode of the cleaning device, so as to adjust the pressure between the scraping strip and the roller brush, and achieve efficient cleaning of the surface of the roller brush assembly and the root of the roller brush assembly, etc. Specifically, during self-cleaning, the heating component can heat the bottom liquid in the cleaning cavity or directly act on the surface of the roller brush assembly to increase the temperature of the roller brush surface. Therefore, by utilizing the high-temperature characteristics of hot water or the heating component, the thermal movement between molecules can be accelerated, making it easier to dissolve stubborn oil stains, and then more effectively dissolving the dirt on the roller brush assembly. After being rinsed with hot water during the self-cleaning process, the stubborn stains on the roller brush can be effectively removed, improving the cleaning effect and cleaning efficiency. At the same time, increasing the interference fit between the scraping strip and the roller brush assembly and controlling the forward rotation of the roller brush assembly can increase the pressure of the scraping strip on the roller brush, making the pressure between the scraping strip and the roller brush greater than that in the cleaning state, so that the dirt dissolved by heating can be extruded or scraped out from the inside and even the depth of the roller brush immediately, further improving the cleaning effect and cleaning efficiency. Thus, through the cooperation of this thermal cleaning and the increase in scraping strip pressure, the cleaning effect on the surface and inside of the roller brush assembly can be significantly improved.

[0011] Furthermore, by responding to the self-cleaning instruction, the system can automatically control the actions of each component without manual intervention, simplifying the operation process, improving the user experience, reducing the time and energy for users to clean manually. This thermal cleaning function can not only remove dirt but also kill bacteria and microorganisms, improve the hygiene level of the cleaning device, ensure the safety of the use environment, and regular self-cleaning operations can prevent dirt accumulation, reduce the wear of the roller brush and other cleaning components, thereby extending the service life of the cleaning device.

[0012] Optionally, when it is detected that the water pump assembly is in the on state, controlling the heating component to be in the on state includes:

[0013] When it is detected that the water pump assembly is in the on state and the suction motor is in the off state, controlling the heating component to be in the on state.

[0014] When the suction motor is turned off, the water pump assembly can evenly distribute the cleaning liquid in the cleaning chamber. After the heating component is started, the cleaning liquid in the cleaning chamber can be heated to increase the temperature of the cleaning liquid, thereby enhancing the cleaning effect. Furthermore, through the hot water or the high-temperature characteristics of the heating component, the dirt on the surface of the roller brush assembly can be more effectively dissolved. During this self-cleaning process, after being rinsed with hot water, the stubborn stains on the surface of the roller brush can be effectively washed away. And when the suction motor is turned off, the airflow inside the system decreases, which helps prevent heat loss of the heating component. In this state, when the heating component is turned on, the temperature of the system can be better controlled to ensure the safe operation of the cleaning device. Moreover, when the suction motor is turned off, the power consumption of the system will decrease. At this time, when the heating component is turned on, the electrical energy resources can be utilized more efficiently, avoiding unnecessary energy consumption. This operation strategy reflects the intelligent control ability of the cleaning system. For users, this intelligent control strategy can simplify the operation process, reduce manual intervention, and improve the user experience.

[0015] Optionally, the cleaning base station further includes a hot air generator; the hot air generator is used to provide hot air in the cleaning chamber; the method includes:

[0016] During the process of the cleaning device performing self-cleaning at the cleaning base station, it at least includes controlling the heating component and / or the hot air generator to be turned on when it is detected that the water pump assembly is in the on state, so as to perform hot cleaning on the roller brush assembly.

[0017] In this way, by using the heating component and the hot air generator simultaneously or separately, multiple cleaning effects can be achieved. That is, the hot air generator can be used to perform hot cleaning on the roller brush assembly, the heating component can also be used to perform hot cleaning on the roller brush assembly, and both can be used simultaneously to perform hot cleaning on the roller brush assembly. That is, when the cleaning liquid is cleaning the roller brush assembly, the hot air generator can quickly heat the roller brush assembly and other components in the cleaning chamber to perform hot cleaning on the components. The hot air provided by the hot air generator can also help soften and remove the stubborn stains and residues on the roller brush, effectively dissolve the stubborn stains on the roller brush assembly, and also help prevent the growth of mold and bacteria, maintaining the hygiene and cleanliness of the device, thereby extending the service life of the device; the heating component can also heat the bottom liquid in the cleaning chamber to effectively dissolve the stubborn stains on the roller brush assembly. And if after the heating component has heated the cleaning liquid for preliminary cleaning, further treatment with hot air can ensure a more thorough cleaning effect on the surface and inside of the roller brush assembly. In this application, the heating component and / or the hot air generator can be selectively turned on according to needs through the intelligent control system, avoiding unnecessary energy consumption, achieving energy conservation and environmental protection, and the system can also intelligently control the working states of the heating component and / or the hot air generator according to the real-time detected states, such as the on state of the water pump assembly, to improve the cleaning effect and device performance.

[0018] Optionally, when it is detected that the water pump assembly is in the on state, controlling the heating component and / or the hot air generator to be in the on state includes:

[0019] When it is detected that the water pump assembly is in the on state and both the hot air generator and the suction motor are in the off state, controlling the heating component to be in the on state.

[0020] In this way, when it is detected that both the hot air generator and the suction motor are off, the heating component is controlled to be turned on, so that the heating component can heat the cleaning liquid to its optimal cleaning temperature, thereby enhancing the cleaning effect, effectively dissolving the dirt on the surface of the roller brush assembly, and then through the flushing of hot water during the self-cleaning process, the stubborn stains on the roller brush surface can be effectively removed. And when the hot air generator and the suction motor are off, the water pump assembly can focus more on delivering the cleaning liquid to the cleaning cavity, while the heating component can more effectively heat these liquids, which can improve the efficiency of the cleaning process and enable the roller brush assembly to be cleaned more thoroughly.

[0021] Optionally, the method further includes:

[0022] When it is detected that the water pump assembly is in the off state and the suction motor is in the on state, controlling the hot air generator to be turned on so that the hot air generator delivers hot air to the cleaning cavity to heat the liquid in the cleaning cavity, and the scraping strip assembly scrapes off the liquid on the roller brush assembly to continue the hot cleaning of the roller brush assembly.

[0023] In this way, during the self-cleaning process, the design of adding hot air and the bottom heating component heats the liquid in the cleaning cavity. The combination of hot water and hot air can better dissolve and remove the stubborn stains and grease on the surface and inside of the roller brush, thereby improving the cleaning effect. And the dual action of hot water and hot air can not only clean the surface of the roller brush, but also deeply clean the gaps and small parts inside the roller brush to ensure thorough cleaning without residue. Coupled with the cooperation with the scraping strip assembly, it not only improves the self-cleaning efficiency of the roller brush, but also can make the roller brush recover cleanliness, greatly reduce stain residue, reduce the risk of mildew and bacteria growth on the roller brush, and the regular automatic cleaning can prevent dirt and impurities from accumulating on the roller brush assembly and other key components, thereby reducing wear and failures and extending the service life of the device.

[0024] Optionally, the cleaning base station further includes a shielding mechanism and a base air duct; the shielding mechanism can shield the air outlet of the base air duct; the method further includes:

[0025] When it is detected that the height of the liquid in the cleaning cavity is greater than the safety threshold, controlling the position of the shielding mechanism to change so as to shield the air outlet of the base air duct.

[0026] In this way, by setting a safety threshold and an occlusion mechanism, liquid overflow and entry into sensitive components can be prevented, the risks of electrical short circuits and mechanical failures can be reduced, the safety of the device can be enhanced, ensuring the safety of users during use, and by real-time monitoring the liquid level in the cleaning chamber and automatically controlling the position of the occlusion mechanism, intelligent liquid level management can be achieved, reducing manual intervention by users and improving the automation level and user experience of the device.

[0027] Optionally, the cleaning base station further includes an occlusion mechanism and a base air duct; the occlusion mechanism is used to change the wind direction of the air outlet of the base air duct; the method further includes:

[0028] When a change in the rotation direction of the roller brush assembly is detected, control the position of the occlusion mechanism to change, so as to change the wind direction of the air outlet of the base air duct.

[0029] A change in the rotation direction of the roller brush assembly may cause uneven cleaning effects in some parts. Therefore, in this application, by adjusting the wind direction, it can be ensured that the hot air can cover all parts of the roller brush assembly. During the rotation of the roller brush assembly, the hot air blows towards the wet surface of the roller brush, or the hot air blows into the gap between the cleaning chamber and the roller brush assembly. Since part of the cleaning liquid in the gap will also be taken away by the roller brush assembly when the roller brush assembly rotates, it can increase the contact area between the hot air, the cleaning liquid and the bristles, thereby improving the heat exchange efficiency. And by directly acting the hot air on the roller brush assembly, it will not affect other components due to excessive temperature. Uniform cleaning can reduce the wear and corrosion of the roller brush assembly and other components, prevent premature aging of other components caused by high temperature, and thus extend the service life of the device. By reasonably controlling the wind direction, overheating and damage caused by the concentration of hot air in a certain part can be avoided. Uniform hot air distribution can ensure the safe operation of the device and prevent failures caused by overheating. This operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the roller brush assembly and automatically adjusting the position of the occlusion mechanism, intelligent wind direction management can be achieved, reducing manual intervention by users and improving the automation level and user experience of the device.

[0030] Optionally, the method further includes:

[0031] When it is detected that the roller brush assembly rotates in the reverse direction, control the squeegee assembly to move from the first position to the second position to reduce the interference fit between the squeegee assembly and the roller brush assembly.

[0032] In this way, when the rotary brush assembly rotates forward, a large interference amount helps to effectively clean the surface of the rotary brush. However, when rotating in the reverse direction, reducing the interference amount can avoid excessive scraping of the rotary brush by the scraping strip, enabling the rotary brush assembly to come into full contact with the liquid, achieving the purpose of rinsing, and thus maintaining the stability of the cleaning effect. This operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the rotary brush assembly and automatically adjusting the position of the scraping strip assembly, intelligent interference amount management can be achieved, reducing manual intervention by the user and improving the automation level and user experience of the device.

[0033] Optionally, the method further includes:

[0034] When the water pump assembly is in the on state, at least when it is detected that the height of the bottom liquid in the cleaning chamber is greater than a preset threshold, control the water pump assembly to switch to the off state.

[0035] In this way, when the water pump assembly is in the on state, the heating component can be controlled to be in the on state, and when it is detected that the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, the water pump assembly is automatically turned off to achieve thermal cleaning of the rotary brush assembly. This comprehensive operation strategy can adapt to different cleaning requirements and operation modes. Whether it is increasing the interference amount, thermal cleaning, or liquid level management, the system can automatically adjust to ensure the best cleaning effect and equipment protection.

[0036] Optionally, the cleaning base station further includes a heating component, and the suction motor is also used to suck the heat of the heating component into the cleaning chamber to realize the flow of hot air in the cleaning chamber; the method further includes:

[0037] When it is detected that the water pump assembly is in the off state and the suction motor is in the on state, control the heating component to be in the on state, so that the suction motor sucks the heat of the heating component into the cleaning chamber to heat the liquid in the cleaning chamber and continue to perform thermal cleaning on the rotary brush assembly.

[0038] In this way, when the hot air generator is damaged or the system does not have a drying function, the combination of the heating component and the suction motor can be used as an emergency alternative to ensure that the cleaning system can still operate normally and achieve the thermal cleaning function. By providing an alternative hot air generation method, the reliability of the system can be improved, and the system downtime caused by a single component failure can be reduced. By intelligently controlling the working states of the heating component and the suction motor, efficient use of energy can be achieved, unnecessary energy consumption can be avoided, and the heating component and the suction motor are only turned on when needed to reduce energy waste. This comprehensive operation strategy can adapt to different cleaning requirements and operation modes. Whether it is thermal cleaning, drying, or energy saving, the system can automatically adjust to ensure the best cleaning effect and equipment protection.

[0039] Optionally, the heating component includes a heating element and a seal. At least part of the heating element is sealed in the seal, and the heating element is installed on the bottom wall of the cleaning cavity through the seal to heat the bottom liquid in the cleaning cavity.

[0040] By setting the heating component, when the floor washer performs self-cleaning, cold water can be heated into hot water, so that the roller brush component can be thermally cleaned. Since at least part of the heating element is sealed in the seal and the seal is installed on the bottom wall of the cleaning cavity, it can prevent water on the cleaning cavity from leaking out from the bottom wall of the cleaning cavity during self-cleaning of the roller brush component. In addition, at least part of the heating element being sealed in the seal can effectively block the heat conduction of the heating element inside the seal in other directions, and only conduct heat from the unsealed part at the top of the heating element.

[0041] In a second aspect, the present application provides a self-cleaning method applied to a cleaning system. The cleaning system includes a cleaning device and a cleaning base station; the cleaning device includes a roller brush component, a water pump component, and a suction motor; the cleaning base station includes a hot air generator and a cleaning cavity; the suction motor is used to provide a suction force for extracting the liquid in the cleaning cavity; the hot air generator is used to provide hot air in the cleaning cavity; the method includes:

[0042] During the process of the cleaning device performing self-cleaning at the cleaning base station, it at least includes controlling one of the water pump component and the suction motor to be in an on state and the other to be in an off state, and controlling the roller brush component to rotate forward and backward alternately when the hot air generator is in an on state.

[0043] Wherein, when the water pump component is in an on state, it at least includes controlling the water pump component to switch to an off state when it is detected that the height of the bottom liquid in the cleaning cavity is greater than a preset threshold.

[0044] It should be noted that the roller brush component is prone to being stained with stubborn stains during the cleaning process, such as stubborn stains like oil and soy sauce. These stains have strong adhesion. In the prior art, when performing self-cleaning operations on these stains, without the assistance of heat flow, it is impossible to dissolve the stubborn stains on the surface and root of the roller brush component, and thus it is difficult to effectively clean, resulting in poor cleaning effects. If the cleaning is not thorough, the remaining stains will cause the roller brush component to mildew, have an odor, and even breed bacteria, affecting the hygiene condition and user experience of the device.

[0045] Compared with the cleaning methods in the prior art, the present application provides a self-cleaning method that makes full use of the function of the hot air generator in the self-cleaning system and enables it to be turned on during the self-cleaning process. Then, the hot air is used to heat the cleaning liquid or directly heat the surface of the roller brush assembly. By utilizing the high-temperature characteristics, the thermal motion between molecules is accelerated, and stubborn stains, especially grease stains, can be dissolved more effectively. It can be understood that this hot air can not only further soften and remove stubborn stains but also prevent the growth of molds and bacteria, maintaining the hygiene of the cleaning device.

[0046] In this way, during the self-cleaning process, there is a situation where the hot air generator is turned on. In the state where the hot air generator is turned on, the hot air can be used to heat the water in the roller brush assembly and the cleaning cavity to achieve hot cleaning of the roller brush assembly and enhance the cleaning effect. And when the hot air generator is turned on, controlling the roller brush assembly to rotate forward and backward alternately can enable the hot air blown by the hot air generator to reach the surface and the root of the roller brush assembly, ensuring that the roller brush assembly is comprehensively cleaned, avoiding dead corners and omissions, and improving the cleaning effect.

[0047] In addition, during the self-cleaning process, the liquid level in the cleaning cavity is monitored in real time. When the liquid level is greater than the preset threshold, the water pump assembly is automatically turned off to prevent liquid overflow and keep the working environment clean and dry. By intelligently controlling the working states of the water pump assembly and the suction motor, efficient use of resources can be achieved, avoiding unnecessary energy consumption and waste of water resources. And when it is detected that the liquid level reaches the preset threshold and the water pump is turned off in a timely manner, the power consumption can be reduced and the energy utilization efficiency can be improved. Therefore, through intelligent liquid level management and hot air control, while achieving hot cleaning of the roller brush assembly, the present application can prevent liquid from entering the electrical components, reduce the risks of electrical short circuits and mechanical failures, and improve the safety of the device.

[0048] Optionally, the cleaning device further includes a squeegee assembly; the squeegee assembly is in interference fit with the roller brush assembly; the method further includes:

[0049] In response to the self-cleaning instruction, control the squeegee assembly to move to the first position to increase the interference amount between the squeegee assembly and the roller brush assembly.

[0050] In this way, by increasing the interference fit between the squeegee assembly and the roller brush assembly, the pressure of the squeegee on the roller brush can be increased, thereby more effectively scraping off dirt and impurities on the surface of the roller brush, improving the cleaning effect. When the hot air generator is turned on, hot air is used to perform thermal cleaning on the roller brush assembly, further enhancing the cleaning effect, especially for removing stubborn stains on the surface of the roller brush. By controlling the roller brush assembly to rotate forward and backward alternately, it is ensured that the entire surface of the roller brush is cleaned, avoiding dead corners and omissions, and improving the cleaning effect. By intelligently controlling the working states of the water pump assembly and the suction motor, efficient use of resources can be achieved. When the liquid level reaches the preset threshold, the water pump assembly is timely turned off, while improving the energy utilization efficiency, reasonably controlling the interference fit and liquid supply, reducing the wear of the squeegee and the roller brush, and extending their service life.

[0051] Optionally, the method further includes:

[0052] When it is detected that the roller brush assembly rotates in the reverse direction, control the squeegee assembly to move from the first position to the second position to reduce the interference fit between the squeegee assembly and the roller brush assembly.

[0053] When it is detected that the roller brush assembly rotates in the forward direction, the squeegee assembly can be controlled to move to the first position to increase the interference fit between the squeegee assembly and the roller brush assembly. A larger interference fit helps to effectively clean the surface of the roller brush. Further, when it is detected that the roller brush assembly rotates in the reverse direction, control the squeegee assembly to move from the first position to the second position to reduce the interference fit between the squeegee assembly and the roller brush assembly. Reducing the interference fit can avoid excessive scraping of the roller brush by the squeegee, enabling the roller brush assembly to fully contact the liquid, achieving the purpose of rinsing, and thus maintaining the stability of the cleaning effect. This mutually coordinated operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the roller brush assembly and automatically adjusting the position of the squeegee assembly, intelligent interference fit management can be achieved, reducing manual intervention by the user, and improving the automation level and user experience of the device.

[0054] Optionally, the cleaning base station further includes a heating component; the heating component is installed on the bottom wall of the cleaning chamber to heat the bottom liquid in the cleaning chamber. The method further includes:

[0055] When it is detected that the water pump assembly is in the on state, control the heating component to be in the on state so that the heating component heats at least the bottom liquid in the cleaning chamber to perform thermal cleaning on the roller brush assembly.

[0056] In this way, by heating the cleaning liquid with the heating component and / or the hot air generator for immersion washing, the roller brush assembly can be cleaned with hot water or hot steam, further enhancing the cleaning effect. Moreover, the combination of hot water and hot air can better dissolve the dirt on the surface of the roller brush assembly and remove stubborn stains and grease on the roller brush surface, thereby improving the cleaning effect. The dual action of hot water and hot air can not only clean the surface of the roller brush but also deeply clean the gaps and small parts inside the roller brush to ensure thorough removal of dirt and bacteria and enhance the overall cleaning effect. Additionally, the cleaning system can automatically adjust the working modes of each component according to the real-time detected status. For example, it can flexibly control the activation of the heating component and / or the hot air generator to ensure the best cleaning effect and equipment protection.

[0057] Optionally, when the water pump assembly is in the on state, it at least includes controlling the water pump assembly to switch to the off state when it is detected that the height of the bottom liquid in the cleaning chamber is greater than a preset threshold, including:

[0058] When it is detected that the water pump assembly is in the on state, the suction motor is in the off state, and the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, control the water pump assembly to switch from the on state to the off state so that the hot air generator delivers hot air into the cleaning chamber to heat the liquid in the cleaning chamber and perform hot cleaning on the roller brush assembly.

[0059] In this way, after the water pump assembly switches from the on state to the off state, by delivering hot air into the cleaning chamber through the hot air generator, the cleaning liquid can be heated by the hot air to further enhance the cleaning effect. Through intelligent liquid level management and component control, such as intelligently controlling the working state of the water pump assembly, efficient use of resources can be achieved, avoiding unnecessary energy consumption and water resource waste.

[0060] Optionally, the hot air generator includes a fan assembly and a heating component; the suction motor is also used to suck the heat of the heating component into the cleaning chamber to achieve the flow of hot air in the cleaning chamber; when the hot air generator is in the on state, controlling one of the water pump assembly and the suction motor to be in the on state and the other to be in the off state, and controlling the roller brush assembly to rotate forward and backward alternately, including:

[0061] At least when the heating component is in the on state and the fan assembly is in the off state, control the suction motor to be in the on state, the water pump assembly to be in the off state, and control the roller brush assembly to rotate forward and backward alternately so that the suction motor sucks the heat of the heating component into the cleaning chamber to heat the liquid in the cleaning chamber and perform hot cleaning on the roller brush assembly.

[0062] In this way, the heat of the heating component is sucked into the cleaning chamber by the suction motor to form a hot air flow, so as to heat the cleaning liquid, and the hot water or hot steam is used to clean the roller brush component, effectively dissolving and removing stubborn stains on the surface and inside of the roller brush component, further enhancing the cleaning effect. By intelligently controlling the working states of the heating component and the suction motor, the energy can be efficiently utilized, unnecessary energy consumption can be avoided, and the combination of the heating component and the suction motor can be used as an emergency alternative to ensure that the cleaning system can still operate normally and realize the hot cleaning function. By providing an alternative hot air generation method, the reliability of the system can be improved, and the system downtime caused by the failure of a single component can be reduced.

[0063] Optionally, the cleaning base station further includes a shielding mechanism and a base air duct; the shielding mechanism is used to shield the air outlet of the base air duct; the method further includes:

[0064] When it is detected that the height of the liquid in the cleaning chamber is greater than the safety threshold, control the position of the shielding mechanism to change so as to shield the air outlet of the base air duct.

[0065] In this way, by setting the safety threshold and the shielding mechanism, liquid overflow and entry into sensitive components can be prevented, the risks of electrical short circuits and mechanical failures can be reduced, the safety of the device can be improved, the safety of the user during use can be ensured, and by real-time monitoring the liquid height in the cleaning chamber and automatically controlling the position of the shielding mechanism, intelligent liquid level management can be realized, manual intervention by the user can be reduced, and the automation level and user experience of the device can be improved.

[0066] Optionally, the cleaning base station further includes a shielding mechanism and a base air duct; the shielding mechanism is used to change the wind direction of the air outlet of the base air duct; the method further includes:

[0067] When it is detected that the rotation direction of the roller brush component changes, control the position of the shielding mechanism to change so as to change the wind direction of the air outlet of the base air duct.

[0068] The change in the rotation direction of the roller brush assembly may cause uneven cleaning effects in some parts. Therefore, by adjusting the wind direction, it can be ensured that the hot air can cover all parts of the roller brush assembly. During the rotation of the roller brush assembly, the hot air blows towards the wet surface of the roller brush, or the hot air blows into the gap between the cleaning chamber and the roller brush assembly. Since part of the cleaning liquid in the gap will also be taken away by the roller brush assembly when the roller brush assembly rotates, it can increase the contact area between the hot air, the cleaning liquid, and the bristles, thereby improving the heat exchange efficiency. And by directly acting on the roller brush assembly with hot air, it will not affect other components due to excessive temperature. Uniform cleaning can reduce the wear and corrosion of the roller brush assembly and other components, prevent the premature aging of other parts caused by high temperature, and thus extend the service life of the equipment. By reasonably controlling the wind direction, it is possible to avoid overheating and damage caused by the concentration of hot air in a certain part. Uniform hot air distribution can ensure the safe operation of the equipment and prevent failures caused by overheating. This operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the roller brush assembly and automatically adjusting the position of the shielding mechanism, intelligent wind direction management can be achieved, reducing the manual intervention of users and improving the automation level and user experience of the equipment.

[0069] Optionally, the method further includes:

[0070] When it is detected that the water pump assembly is in the closed state, the suction motor is in the on state, and the hot air generator is switched from the off state to the on state, control the hot air generator to be in the on state for at least some periods.

[0071] In this way, by turning on the hot air generator for some periods, the roller brush assembly can be further cleaned and disinfected with hot air to enhance the cleaning effect. By turning on the suction motor, the hot air can be evenly distributed in the cleaning chamber to ensure that all components can be fully cleaned. Furthermore, by intelligently controlling the on period of the hot air generator, efficient use of energy can be achieved, avoiding unnecessary energy consumption, turning on the hot air generator only when needed, reducing energy waste, and the above comprehensive operation strategy can adapt to different cleaning requirements and operation modes, improving the flexibility of hot cleaning.

[0072] In a third aspect, the present application provides a self-cleaning method applied to a cleaning system. The cleaning system includes a cleaning device and a cleaning base station; the cleaning device includes a roller brush assembly, a water pump assembly, a suction motor, and a wiper blade assembly; the cleaning base station includes a hot air generator and a cleaning chamber; the suction motor is used to provide suction force for the extraction of liquid in the cleaning chamber; the hot air generator is used to provide hot air in the cleaning chamber; the wiper blade assembly is in interference fit with the roller brush assembly; the method includes:

[0073] In response to a self-cleaning instruction, control the wiper blade assembly to move to a first position to increase the interference amount between the wiper blade assembly and the roller brush assembly;

[0074] During the process of the cleaning device performing self - cleaning while located at the cleaning base station, it at least includes controlling one of the water pump assembly and the suction motor to be in an on state and the other to be in an off state when the hot - air generator is in an on state, and controlling the roller brush assembly to rotate forward and backward alternately.

[0075] It should be noted that when performing self - cleaning operations on stubborn stains on the roller brush assembly in the prior art, there is no assistance of heat flow, so it is impossible to dissolve the stubborn stains on the surface and root of the roller brush assembly. Moreover, the interference fit between the existing scraping strip and the roller brush assembly is fixed and cannot be adjusted according to the actual cleaning requirements. This design limits the extrusion force of the scraping strip on the roller brush assembly and the ability of hot cleaning, resulting in difficulty in removing stubborn stains at the root of the roller brush bristles and other areas. After long - term use of the roller brush assembly, problems such as mildew, bad smell, and even bacterial growth are likely to occur, affecting the hygiene condition and service life of the cleaning device.

[0076] Compared with the cleaning methods in the prior art, the present application can control the interference fit between the scraping strip assembly and the roller brush assembly according to the working mode of the cleaning device to increase the pressure of the scraping strip on the roller brush, so that the pressure between the scraping strip and the roller brush is greater than that in the cleaning state. In addition, the present application makes full use of the function of the hot - air generator and can also turn it on during the self - cleaning process. Then, it uses hot air to heat the cleaning liquid or directly heat the surface of the roller brush assembly, thereby more effectively heating and dissolving stubborn stains. Coupled with the interference fit with the scraping strip assembly, it is possible to extrude or scrape out the heated and dissolved dirt from the inside and even the deep part of the roller brush in the first time, ensuring the cleanliness of the roller brush assembly.

[0077] Among them, during the self - cleaning process, by controlling one of the water pump assembly and the suction motor to be turned on and the other to be turned off, and controlling the roller brush assembly to rotate forward and backward alternately, each part of the roller brush assembly can be cleaned more comprehensively, preventing the generation of dead corners. And by alternately turning on the water pump assembly and the suction motor, the usage of water and electricity can be effectively controlled, avoiding resource waste and achieving the purpose of energy conservation and environmental protection. By rotating the roller brush assembly forward and backward alternately, the roller brush can be evenly worn, avoiding unbalanced wear of the roller brush caused by single - direction wear and premature damage. In the present application, since the hot - air generator can be turned on to heat the liquid in the cleaning cavity and the roller brush assembly, therefore, in cooperation with the operation of the water pump assembly or the suction motor, efficient cleaning of the surface and root of the roller brush assembly can be achieved. And the above process is automated. Through the above - mentioned automated self - cleaning process, there is no need for manual operation by the user, which can also improve the user experience and convenience.

[0078] Optionally, the hot air generator includes a fan assembly and a heating assembly; the suction motor is further configured to suck the heat of the heating assembly into the cleaning cavity to achieve the flow of hot air in the cleaning cavity; when the hot air generator is in the on state, control one of the water pump assembly and the suction motor to be in the on state and the other to be in the off state, and control the brush roller assembly to rotate forward and backward alternately, including:

[0079] At least when the heating assembly is in the on state and the fan assembly is in the off state, control the suction motor to be in the on state, the water pump assembly to be in the off state, and control the brush roller assembly to rotate forward and backward alternately, so that the suction motor sucks the heat of the heating assembly into the cleaning cavity, heats the liquid in the cleaning cavity, and performs thermal cleaning on the brush roller assembly.

[0080] In this way, the heat of the heating assembly is sucked into the cleaning cavity by the suction motor to form a hot air flow to heat the cleaning liquid, and the brush roller assembly is cleaned with hot water or hot steam, effectively dissolving and removing stubborn stains on the surface and inside of the brush roller assembly, further enhancing the cleaning effect. By intelligently controlling the working states of the heating assembly and the suction motor, efficient use of energy can be achieved, unnecessary energy consumption can be avoided, and the combination of the heating assembly and the suction motor can be used as an emergency alternative to ensure that the cleaning system can still operate normally and achieve the thermal cleaning function. By providing an alternative hot air generation method, the reliability of the system can be improved, and the system downtime caused by a single component failure can be reduced.

[0081] Optionally, the method further includes:

[0082] When it is detected that the brush roller assembly rotates in the reverse direction, control the squeegee assembly to move from the first position to the second position to reduce the interference fit between the squeegee assembly and the brush roller assembly.

[0083] In this way, when the brush roller assembly rotates forward, a larger interference fit helps to effectively clean the surface of the brush roller. However, when rotating in the reverse direction, reducing the interference fit can avoid excessive scraping of the brush roller by the squeegee, enabling the brush roller assembly to come into full contact with the liquid for the purpose of rinsing, thereby maintaining the stability of the cleaning effect. This operating strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the brush roller assembly and automatically adjusting the position of the squeegee assembly, intelligent interference fit management can be achieved, reducing manual intervention by the user and improving the automation level and user experience of the device.

[0084] Optionally, the method further includes:

[0085] During the self-cleaning process of the cleaning device at the cleaning base station, control the cleaning base station to charge the cleaning device.

[0086] Charge the cleaning device during the self - cleaning process to ensure that the device has enough power to continue performing other cleaning tasks after completing self - cleaning, extend the working time of the device, and by charging during the self - cleaning process, the downtime of the device due to insufficient power can be reduced. Since self - cleaning and charging are carried out simultaneously, the time when the device stays in the base station is fully utilized, improving the time utilization rate and avoiding occupying extra time for charging alone. Also, by performing self - cleaning and charging simultaneously, the working state of the device can be quickly restored, improving the overall cleaning efficiency, so that users do not need to arrange the charging time of the cleaning device separately. The system automatically completes charging during the self - cleaning process, simplifying the operation process and enhancing the user experience.

[0087] Optionally, the method further includes:

[0088] After the self - cleaning of the cleaning device located in the cleaning base station is completed, control the water pump assembly to be in the closed state, and both the hot - air generator and the suction motor to be in the on state to dry the roller brush assembly.

[0089] In this way, by drying the roller brush assembly, long - term retention of moisture can be prevented, the growth of mold and bacteria can be inhibited, the hygiene and cleanliness of the device can be maintained, which helps to keep the hygiene of the roller brush assembly and the cleaning cavity, reducing the risk of odor and bacteria spread. Through the dual action of the hot - air generator and the suction motor, a rapid drying effect can be achieved, preventing moisture from staying in the device interior for a long time, thereby extending the service life of the device.

[0095] Wherein, when the water pump assembly is in an on state, at least when it is detected that the height of the bottom liquid in the cleaning chamber is greater than a preset threshold, the water pump assembly is controlled to switch to an off state.

[0114] Through the above-mentioned drawings, the specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0115] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. For example, the first device and the second device are only used to distinguish different devices, and their sequence is not limited. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and "first", "second", etc. do not necessarily mean different.

[0116] It should be noted that in the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly, using words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0117] In the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression below refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, c can be single or multiple.

[0118] When the cleaning device is contaminated with stubborn stains, such as oil stains, soy sauce stains, etc., the self-cleaning effect of the cleaning device is not good. Especially at the roots of the bristles of the roller brush assembly, due to the complex structure, it is difficult for the existing water flow flushing or mechanical scraping to thoroughly clean the roots, resulting in the cleanliness not meeting the requirements. If the cleaning is not thorough, the residual stains will gradually accumulate, causing the roller brush assembly to mildew, have an unpleasant smell, and even breed bacteria, which not only affects the use effect of the cleaning device but may also have an adverse impact on the health of the user.

[0119] Since high temperature can accelerate the dissolution of oil stains and stubborn stains and improve the cleaning activity of the cleaning agent, during the self-cleaning process, the cleaning water can be heated to improve the self-cleaning efficiency of the roller brush assembly.

[0120] In view of the above problems and considerations, the embodiment of the present application provides a self-cleaning method. During the self-cleaning process, by designing a heating component at the bottom of the cleaning base station, the liquid in the cleaning cavity is heated, or the heating component directly acts on the surface of the roller brush assembly. Then, by utilizing the high-temperature characteristics of hot water or the heating component, stubborn stains and grease can be better dissolved and removed, thereby improving the cleaning effect. And by controlling the interference amount between the scraping strip assembly and the roller brush assembly, the dirt and residues on the roller brush can be effectively removed. In this way, under the dual action of hot water and scraping, the self-cleaning efficiency of the roller brush assembly can be improved, and the roller brush assembly can be restored to cleanliness, greatly reducing the stain residue and reducing the risk of roller brush mildew and bacteria growth.

[0121] Optionally, during the self-cleaning process, a hot air design can also be added. During the self-cleaning process, the hot air generator is started at least in one stage to blow hot air towards the roller brush assembly. This hot air generator does not require additional configuration and can share the heater used for drying. In this way, by adding hot air, not only the surface of the roller brush assembly can be cleaned, but also the gaps and small parts inside the roller brush assembly can be deeply cleaned to ensure thorough cleaning without residue.

[0122] Optionally, the self-cleaning method provided by the present application is applied to a cleaning system, and the cleaning system includes a cleaning device and a cleaning base station; the cleaning system can be a self-mobile cleaning system or a handheld cleaning system. The embodiment of the present application does not make specific limitations here. The cleaning device can be devices such as a floor sweeping robot and a floor washer. The embodiment of the present application does not make specific limitations on the type of the cleaning device. For the convenience of description below, the cleaning device is taken as a floor washer as an example, but it does not mean that the cleaning device is limited to a floor washer.

[0123] Exemplarily, Figure 1 and Figure 2 are partial structural schematic diagrams of the cleaning system provided by the embodiment of the present application, such as Figure 1 and Figure 2As shown in the figure, the cleaning device includes a roller brush assembly 200, a water pump assembly, a suction motor, and a squeegee assembly (not shown in the figure); the cleaning base station 100 includes a heating assembly 2 and a cleaning chamber 11; the suction motor is used to provide suction force for the extraction of the liquid in the cleaning chamber 11; the squeegee assembly is in interference fit with the roller brush assembly 200; the heating assembly 2 is installed on the bottom wall of the cleaning chamber 11 to heat the bottom liquid in the cleaning chamber 11 and can also directly heat the roller brush assembly 200; among them, the roller brush assembly 200 includes components such as a roller brush, and the squeegee assembly includes components such as a squeegee.

[0124] Optionally, the cleaning base station 100 further includes a base body 1, and the base body 1 has a cleaning chamber 11 for accommodating the item to be cleaned; the heating assembly 2 includes a heating element 21 and a seal 22, at least part of the heating element 21 is sealed in the seal 22, and the heating element 21 is installed on the bottom wall of the cleaning chamber 11 through the seal 22 to heat the liquid in the cleaning chamber 11.

[0125] Among them, with reference to Figure 3 , in the present application, by setting the heating assembly 2, cold water can be heated into hot water during the self-cleaning of the floor washer, so that the roller brush assembly 200 can be thermally cleaned. At least part of the heating element 21 is sealed in the seal 22, and the seal 22 is installed on the bottom wall of the cleaning chamber 11, so that when the roller brush assembly 200 is self-cleaned, the water on the cleaning chamber 11 will not leak from the bottom wall of the cleaning chamber 11; in addition, at least part of the heating element 21 is sealed in the seal 22, which can effectively block the heat conduction of the heating element 21 inside the seal 22 in other directions, and only conduct heat from the unsealed part at the top of the heating element 21 (the part corresponding to the roller brush assembly of the floor washer).

[0126] Optionally, the cleaning base station 100 further includes a hot air generator, and the hot air generator is used to provide hot air in the cleaning chamber 11; it should be noted that the hot air generator includes a fan assembly and a heating assembly. When the fan assembly does not work or there is no fan assembly in the cleaning base station 100, the suction motor can suck the heat of the heating assembly into the cleaning chamber 11 to realize the flow of hot air in the cleaning chamber 11.

[0127] In this way, the present application does not need to be equipped with an additional heater. By sharing with the hot air generator used for drying, the volume and weight of the base are reduced, and the design cost of the cleaning base station is also reduced.

[0128] Optionally, the cleaning base station 100 further includes a shielding mechanism and a base air duct; the shielding mechanism can shield the air outlet 111 of the base air duct or change the wind direction of the air outlet 111 of the base air duct. The functions and effects of the shielding mechanism in the embodiments of the present application are not specifically limited, and it can be determined based on the application scenario requirements of the cleaning device.

[0129] Exemplarily, when the roller brush assembly 200 of the floor washer is placed on the cleaning chamber 11 for self-cleaning, the cold water ejected by the roller brush assembly 200 flows to the cleaning chamber 11, and the heating element 21 heats the cold water to perform self-cleaning on the roller brush assembly 200 based on hot water.

[0130] Exemplarily, Figure 4 FIG. is a schematic diagram of an application scenario provided by an embodiment of the present application. As Figure 4 shown, this application scenario can be applied to a cleaning system in a home scenario. Taking a floor washer as the cleaning device, this application scenario includes a floor washer 400 and a cleaning base station 100; the floor washer 400 includes a roller brush assembly, a water pump assembly, and a squeegee assembly, and the cleaning base station 100 includes a heating assembly and a cleaning chamber.

[0131] When the floor washer 400 is placed on the cleaning base station 100, the floor washer 400 can perform a self-cleaning function. The floor washer 400 can control the squeegee assembly to reciprocate in response to a self-cleaning instruction to achieve squeezing and cleaning of the roller brush assembly. During the self-cleaning process of the floor washer 400, when it is detected that the water pump assembly is in an on state, the heating assembly can be controlled to be in an on state to enable the heating assembly to heat the bottom liquid in the cleaning chamber and achieve thermal cleaning of the roller brush assembly.

[0132] Optionally, the cleaning base station 100 may further include a hot air generator. In this way, during the self-cleaning process of the floor washer 400, the hot air generator can also be controlled to be in an on state to provide hot air in the cleaning chamber for thermal cleaning of the roller brush assembly. In this way, through the design of adding hot air and the heating assembly, the liquid in the cleaning chamber is heated, and the combination of hot water and hot air can better dissolve and remove stubborn stains and grease on the surface and inside of the roller brush assembly, thereby improving the cleaning effect. Moreover, the dual action of hot water and hot air can not only clean the surface of the roller brush but also deeply clean the gaps and small parts inside the roller brush to ensure thorough cleaning without residue.

[0133] In this way, thermal cleaning not only improves the self-cleaning efficiency of the roller brush assembly but also enables the roller brush assembly to be restored to cleanliness, greatly reducing stain residue and reducing the risk of mildew and bacteria growth on the roller brush assembly.

[0134] It should be noted that this cleaning system can also be applied to shopping mall scenarios, school scenarios, and office scenarios. The embodiments of the present application do not limit the specific application scenarios, and the above are only illustrative examples.

[0135] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be 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 repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0136] Figure 5 This is a schematic flowchart of a self-cleaning method provided by an embodiment of the present application. Taking the cleaning system as the execution entity as an example, as Figure 5 shown, the self-cleaning method includes the following steps:

[0137] S501. In response to the self-cleaning instruction, control the squeegee assembly to move to the first position to increase the interference amount between the squeegee assembly and the roller brush assembly, and control the roller brush assembly to rotate forward.

[0138] Among them, the present application embodiment does not specifically limit the sequence of the control logics of the roller brush assembly and the squeegee assembly. For example, in response to the self-cleaning instruction, the squeegee assembly can be controlled to move to the first position first, and then the roller brush assembly can be controlled to rotate forward, or the roller brush assembly can be controlled to rotate forward first, and then the squeegee assembly can be controlled to move to the first position. Or, the squeegee assembly can be controlled to move to the first position and the roller brush assembly can be controlled to rotate forward simultaneously.

[0139] In the embodiment of the present application, the interference amount between the squeegee assembly and the roller brush assembly refers to the degree of mechanical interference between the squeegee assembly and the roller brush assembly, that is, when the squeegee assembly contacts the roller brush assembly, the depth or tightness of the squeegee assembly pressed into the surface of the roller brush. By increasing the interference amount, the cleaning effect of the squeegee assembly on the surface of the roller brush can be improved, because greater pressure can more effectively remove dirt and impurities attached to the roller brush assembly.

[0140] Exemplarily, during the self-cleaning process, by controlling the position of the squeegee assembly, the interference amount is adjusted to optimize the cleaning effect. For example, in response to the self-cleaning instruction, the squeegee assembly moves to the first position to increase the interference amount, thereby enhancing the cleaning effect.

[0141] It should be noted that in response to the self-cleaning instruction, the squeegee assembly moves to the first position, and at this time, the roller brush assembly is default to rotate forward. In actual applications, the present application embodiment does not limit the specific rotation direction of the roller brush assembly, which can be set based on the application scenario requirements or can be set manually.

[0142] Optionally, the self-cleaning instruction can be an instruction issued by the user based on the application (APP) of the terminal device, or an instruction automatically generated by the cleaning system based on the recognized degree of dirt of the roller brush assembly. The present application embodiment does not specifically limit this. Among them, the terminal device establishes a communication connection with the cleaning system to control the cleaning system based on the APP.

[0143] S502. During the self-cleaning process of the cleaning device at the cleaning base station, it at least includes controlling the heating component to be in an on state when it is detected that the water pump component is in an on state, so that the heating component heats at least the bottom liquid in the cleaning cavity to perform thermal cleaning on the roller brush component.

[0144] In some embodiments, the heating component is installed in the bottom wall of the cleaning cavity of the cleaning base station. During the process of the cleaning device returning to the cleaning base station for self-cleaning, when it is detected that the water pump component is in an on state, the heating component is controlled to be in an on state to heat the bottom liquid in the cleaning cavity, and then the roller brush component is cleaned based on the hot water. Alternatively, when the heating component is in an on state, the surface of the roller brush component can be heated to dissolve the dirt on the roller brush component.

[0145] Among them, during the process of cleaning the roller brush component with hot water, the roller brush component can be controlled to rotate forward. Since the scraping strip component moves to the first position, the interference amount between the scraping strip component and the roller brush component is increased, so that the roller brush component is subjected to press-in cleaning, thereby optimizing the cleaning effect of hot water cleaning.

[0146] It should be noted that when the heating component is controlled to be in an on state, the on state or off state of the roller brush component and the suction motor is not specifically limited in the embodiments of the present application. For example, when the roller brush component is in an off state, the roller brush component may be in the soaking stage, or when the roller brush component is in an on state, the roller brush component may cooperate with the scraping strip component to perform thermal cleaning.

[0147] Therefore, in the embodiments of the present application, according to the working mode of the cleaning device, the interference amount between the scraping strip component and the roller brush component is controlled to adjust the pressure between the scraping strip and the roller brush. Specifically, during self-cleaning, the heating component can heat the bottom liquid in the cleaning cavity or directly act on the surface of the roller brush component. By using the high-temperature characteristics of hot water or the heating component, the thermal motion between molecules can be accelerated, making it easier to dissolve stubborn grease stains, and then more effectively dissolving the dirt on the roller brush component. After being rinsed with hot water during the self-cleaning process, the stubborn stains on the roller brush can be effectively removed, improving the cleaning effect and cleaning efficiency. At the same time, increasing the interference amount between the scraping strip and the roller brush component and controlling the roller brush component to rotate forward can increase the pressure of the scraping strip on the roller brush, so that the pressure between the scraping strip and the roller brush is greater than that in the cleaning state, thereby being able to squeeze or scrape out the heated and dissolved dirt from the inside and even the depth of the roller brush in the first time, further improving the cleaning effect and cleaning efficiency. Thus, through the cooperation of this thermal cleaning and the increase in scraping strip pressure, the cleaning effect on the surface and inside of the roller brush component can be significantly improved.

[0148] It should be noted that in the self-cleaning operation of the prior art, without the assistance of hot water, it is impossible to dissolve the oil stains on the surface and root of the roller brush assembly, resulting in a significant decline in the cleaning effect. Moreover, the interference fit between the existing scraping strip and the roller brush assembly is fixed, making it impossible to adjust the interference fit between the scraping strip and the roller brush assembly according to actual cleaning needs. This design limits the extrusion force of the scraping strip on the roller brush assembly, making it difficult to remove stubborn stains at the root of the roller brush bristles and other areas. Due to this unsatisfactory cleaning effect of the cooperation, it is impossible to achieve a strong extrusion of the roller brush assembly during cleaning to squeeze out the dirt at the root of the roller brush assembly, thereby reducing the cleaning effect. Compared with the cleaning method in the prior art, the present application can achieve efficient cleaning of the surface and root of the roller brush assembly based on the above methods.

[0149] Moreover, by responding to the self-cleaning instruction, the system of the present application can automatically control the actions of each component without manual intervention, simplifying the operation process, improving the user experience, and reducing the time and effort of manual cleaning by the user. This hot cleaning function can not only remove dirt but also kill bacteria and microorganisms, improving the hygiene level of the cleaning device, ensuring the safety of the use environment, and preventing dirt accumulation through regular self-cleaning operations, reducing wear on the roller brush assembly and other cleaning components, thereby extending the service life of the cleaning device.

[0150] Optionally, when it is detected that the water pump assembly is in the on state, controlling the heating component to be in the on state includes:

[0151] When it is detected that the water pump assembly is in the on state and the suction motor is in the off state, controlling the heating component to be in the on state.

[0152] Exemplarily, during the soaking stage of the roller brush assembly, when the cleaning system detects that the water pump assembly is in the on state and the suction motor is in the off state, it controls the heating component to be in the on state. At this time, the liquid in the cleaning cavity can be heated based on the heating component to perform hot soaking on the roller brush assembly; or, during the pipeline cleaning stage, when the cleaning system detects that the water pump assembly is in the on state and the suction motor is in the off state, it can also control the heating component to be in the on state. At this time, hot water can flow through the pipeline to perform hot cleaning on the pipeline wall.

[0153] It should be noted that the present application embodiment does not specifically limit the stage at which the cleaning system detects that the water pump assembly is in the on state and the suction motor is in the off state. The above is only an example for illustration.

[0154] When the suction motor is turned off, the water pump assembly can evenly distribute the cleaning liquid in the cleaning chamber. After the heating component is started, the cleaning liquid in the cleaning chamber can be heated to increase the temperature of the cleaning liquid, thereby enhancing the cleaning effect. Furthermore, by utilizing the high-temperature characteristics of hot water or the heating component, the dirt on the surface of the roller brush assembly can be more effectively dissolved. During this self-cleaning process, after flushing with hot water, the stubborn stains on the surface and inside of the roller brush can be effectively washed away. And when the suction motor is turned off, the airflow inside the system decreases, which helps prevent heat loss of the heating component. In this state, when the heating component is turned on, the temperature of the system can be better controlled to ensure the safe operation of the cleaning device. Moreover, when the suction motor is turned off, the power consumption of the system will decrease. At this time, when the heating component is turned on, the electrical energy resources can be utilized more efficiently, avoiding unnecessary energy consumption. This operation strategy reflects the intelligent control ability of the cleaning system. For users, this intelligent control strategy can simplify the operation process, reduce manual intervention, and improve the user experience.

[0155] Optionally, the cleaning base station further includes a hot air generator; the hot air generator is used to provide hot air in the cleaning chamber; the method includes:

[0156] During the self-cleaning process of the cleaning device at the cleaning base station, it at least includes controlling the heating component and / or the hot air generator to be turned on when it is detected that the water pump assembly is in the on state, so as to perform hot cleaning on the roller brush assembly.

[0157] In some embodiments, when it is detected that the water pump assembly is in the on state, only the heating component can be controlled to be turned on to perform hot cleaning on the roller brush assembly. Or, when it is detected that the water pump assembly is in the on state, only the hot air generator can be controlled to be turned on, which can also achieve hot cleaning of the roller brush assembly. In this way, the two can cooperate and be flexibly configured, both of which can achieve hot cleaning of the roller brush assembly. When one component, such as the heating component, has a problem, the other component, such as the hot air generator, can be controlled to be turned on to ensure the stable operation of the system.

[0158] In other embodiments, when it is detected that the water pump assembly is in the on state, the heating component and the hot air generator can be controlled to be turned on simultaneously to perform hot cleaning on the roller brush assembly. In this way, the heating component heats the liquid for hot cleaning, while the hot air generator provides hot air, which can further enhance the cleaning effect of hot cleaning and ensure that the roller brush assembly is thoroughly cleaned.

[0159] In this way, by using the heating component and the hot air generator simultaneously or separately, multiple cleaning effects can be achieved. That is, the hot air generator can be used to perform hot cleaning on the roller brush assembly, the heating component can also be used to perform hot cleaning on the roller brush assembly, and both can be used simultaneously to perform hot cleaning on the roller brush assembly. When the hot air generator is cleaning the roller brush assembly with cleaning liquid, it can quickly heat the roller brush assembly and other components in the cleaning cavity to perform hot cleaning on the components. The hot air provided by the hot air generator can also help soften and remove stubborn stains and residues on the roller brush, effectively dissolve the stubborn stains on the roller brush assembly, and help prevent the growth of mold and bacteria, maintaining the hygiene and cleanliness of the device, thereby extending the service life of the device. The heating component can also heat the bottom liquid in the cleaning cavity to effectively dissolve the stubborn stains on the roller brush assembly. Moreover, if the cleaning liquid has been preliminarily cleaned by the heating component and then further processed by hot air, it can ensure a more thorough cleaning effect on the surface and inside of the roller brush assembly. In this application, the heating component and / or the hot air generator can be selectively turned on according to needs through the intelligent control system to avoid unnecessary energy consumption, achieve energy conservation and environmental protection, and the system can also intelligently control the working states of the heating component and / or the hot air generator according to the real-time detected states, such as the on state of the water pump assembly, to improve the cleaning effect and device performance.

[0160] Optionally, when it is detected that the water pump assembly is in the on state, controlling the heating component and / or the hot air generator to be in the on state includes:

[0161] When it is detected that the water pump assembly is in the on state and both the hot air generator and the suction motor are in the off state, controlling the heating component to be in the on state.

[0162] In the embodiment of this application, if it is detected that the water pump assembly is in the on state and both the hot air generator and the suction motor are in the off state, then the heating component needs to be controlled to be in the on state. At this time, hot cleaning of the roller brush assembly can be performed, and when both the hot air generator and the suction motor are off, the overall energy consumption of the system is reduced. In this case, turning on the heating component can more efficiently utilize the electric energy resources and avoid unnecessary energy consumption.

[0163] Therefore, when the hot air generator and the suction motor are both detected to be turned off in the embodiments of the present application, the heating component is controlled to be turned on, so that the heating component can heat the cleaning liquid to its optimal cleaning temperature, thereby enhancing the cleaning effect, effectively dissolving the dirt on the surface of the roller brush assembly, and then through the flushing of hot water during the self-cleaning process, the stubborn stains on the roller brush can be effectively removed. Moreover, when the hot air generator and the suction motor are turned off, the water pump assembly can focus more on delivering the cleaning liquid to the cleaning cavity, while the heating component can heat these liquids more effectively, which can improve the efficiency of the cleaning process and enable the roller brush assembly to be cleaned more thoroughly.

[0164] Optionally, the method further includes:

[0165] When it is detected that the water pump assembly is in the off state and the suction motor is in the on state, the hot air generator is controlled to be turned on, so that the hot air generator delivers hot air to the cleaning cavity to heat the liquid in the cleaning cavity, and the scraping strip assembly scrapes off the liquid on the roller brush assembly to continue the hot cleaning of the roller brush assembly.

[0166] In this step, when it is detected that the water pump assembly is turned off, the system no longer adds new liquid to the cleaning cavity, but uses the existing liquid for cleaning. By turning on the hot air generator to heat the existing liquid to a higher temperature and cooperating with the scraping strip assembly, the cleaning effect can be enhanced. Among them, the high-temperature liquid can more effectively dissolve and remove the stubborn stains on the roller brush assembly.

[0167] It should be noted that hot air can not only heat the liquid, but also accelerate the evaporation process of the liquid. When the suction motor is turned on, the combination of hot air and suction can quickly dry the roller brush assembly and other components in the cleaning cavity to prevent excessive moisture from remaining.

[0168] Therefore, in the self-cleaning process of the embodiments of the present application, the design of hot air and the bottom heating component is added to heat the liquid in the cleaning cavity. The combination of hot water and hot air can better dissolve and remove the stubborn stains and grease on the surface and inside of the roller brush, thereby improving the cleaning effect. Moreover, the dual action of hot water and hot air can not only clean the surface of the roller brush, but also deeply clean the gaps and small parts inside the roller brush to ensure thorough cleaning without residue. In addition, cooperating with the scraping strip assembly, it not only improves the self-cleaning efficiency of the roller brush, but also can make the roller brush recover cleanliness, greatly reduce stain residue, reduce the risk of roller brush mildew and bacteria growth, and regular automatic cleaning can prevent dirt and impurities from accumulating on the roller brush assembly and other key components, thereby reducing wear and failures and extending the service life of the device.

[0169] The above-mentioned automated cleaning process reduces the need for manual intervention. The system will automatically complete the cleaning task, which not only saves time but also improves the user experience.

[0170] Optionally, the cleaning base station further includes a shielding mechanism and a base air duct; the shielding mechanism can shield the air outlet of the base air duct; the method further includes:

[0171] When it is detected that the height of the liquid in the cleaning chamber is greater than the safety threshold, control the position of the shielding mechanism to change so as to shield the air outlet of the base air duct.

[0172] In the embodiments of the present application, the safety threshold is a preset height threshold for ensuring that the liquid in the cleaning chamber will not flow back from the air outlet, and the safety threshold is set greater than based on the height of the air outlet. The embodiments of the present application do not make specific limitations on the size of the safety threshold.

[0173] When the height of the liquid in the cleaning chamber exceeds the safety threshold, shielding the air outlet of the base air duct can prevent the liquid from being blown out of the cleaning chamber, avoid the liquid from overflowing to the outside of the device, keep the working environment clean and dry, and can also prevent the liquid from entering the base air duct and other sensitive components based on the air outlet, avoiding damage to the electrical components and mechanical components caused by the liquid, thereby extending the service life of the device.

[0174] It should be noted that the embodiments of the present application do not make specific limitations on the specific installation position of the shielding mechanism, and its installation position can be such that it can shield the air outlet of the base air duct.

[0175] Therefore, by setting the safety threshold and the shielding mechanism in the embodiments of the present application, it is possible to prevent the liquid from overflowing and entering sensitive components, reduce the risk of electrical short circuits and mechanical failures, improve the safety of the device, ensure the safety of users during use, and through real-time monitoring of the liquid height in the cleaning chamber and automatically controlling the position of the shielding mechanism, intelligent liquid level management can be achieved, reducing manual intervention by users and improving the automation level and user experience of the device.

[0176] Optionally, the cleaning base station further includes a shielding mechanism and a base air duct; the shielding mechanism is used to change the wind direction of the air outlet of the base air duct; the method further includes:

[0177] When it is detected that the rotation direction of the roller brush assembly changes, control the position of the shielding mechanism to change so as to change the wind direction of the air outlet of the base air duct.

[0178] In the embodiments of the present application, different rotation directions of the roller brush assembly require different wind directions to ensure that all parts of the roller brush assembly can be evenly processed. Therefore, when it is detected that the rotation direction of the roller brush assembly changes, by changing the wind direction of the air outlet of the base air duct, it can be ensured that the hot air or air flow always acts on the roller brush assembly at the best angle and direction, thereby improving the cleaning and drying effects.

[0179] It should be noted that the shielding mechanism can be provided in the form of a plate body or a knob. The embodiments of the present application do not specifically limit the setting form of the shielding mechanism. For example, the setting method of the plate body at the outlet of the air outlet can be changed to prevent water from flowing into the base while not affecting the air outlet.

[0180] In some embodiments, when the rotary brush assembly rotates forward, the wind direction at the air outlet of the base air duct is positive and slightly upward at this time. If it is detected that the rotation direction of the rotary brush assembly changes to reverse rotation, the position of the shielding mechanism is controlled to move above the air outlet of the base air duct to block part of the upper air outlet or cooperate with the air outlet to guide the air flow out, so that the wind direction at the air outlet of the base air duct becomes positive and slightly downward; wherein, the positive wind direction can refer to the direction perpendicular to the outlet air as positive.

[0181] In other embodiments, when the rotary brush assembly rotates in the reverse direction, the wind direction at the air outlet of the base air duct is positive and slightly downward at this time. If it is detected that the rotation direction of the rotary brush assembly changes to forward rotation, the position of the shielding mechanism is controlled to move below the air outlet of the base air duct to block part of the lower air outlet or cooperate with the air outlet to guide the air flow out, so that the wind direction at the air outlet of the base air duct becomes positive and slightly upward; in this way, by adjusting the wind direction, the air flow can be guided more effectively, cooperating with the rotation direction of the rotary brush assembly, optimizing the air flow path, and making the use of the air flow reach the optimum.

[0182] The change in the rotation direction of the rotary brush assembly may cause uneven cleaning effects in some parts. Therefore, in the embodiments of the present application, by adjusting the wind direction, it can be ensured that the hot air can cover all parts of the rotary brush assembly. During the rotation of the rotary brush assembly, the hot air blows towards the wet surface of the rotary brush, or the hot air blows into the gap between the cleaning chamber and the rotary brush assembly. Since part of the cleaning liquid in the gap will also be taken away by the rotary brush assembly when the rotary brush assembly rotates, the contact area between the hot air and the cleaning liquid and the bristles can be increased, thereby improving the heat exchange efficiency. And by directly acting on the rotary brush assembly with hot air, it will not affect other components due to excessive temperature. Uniform cleaning can reduce the wear and corrosion of the rotary brush assembly and other components, prevent the premature aging of other components caused by high temperature, and thus extend the service life of the equipment. By reasonably controlling the wind direction, it is possible to avoid the concentration of hot air in a certain part resulting in overheating and damage. Uniform hot air distribution can ensure the safe operation of the equipment and prevent failures caused by overheating. This operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the rotary brush assembly and automatically adjusting the position of the shielding mechanism, intelligent wind direction management can be achieved, reducing the manual intervention of users and improving the automation level and user experience of the equipment.

[0183] Optionally, the method further includes:

[0184] When it is detected that the roller brush assembly rotates in the reverse direction, control the wiper assembly to move from the first position to the second position to reduce the interference fit between the wiper assembly and the roller brush assembly.

[0185] In the embodiment of the present application, since the wiper assembly is controlled to move from the first position to the second position, the interference fit between the wiper assembly and the roller brush assembly is reduced, so that the roller brush assembly can be in full contact with the liquid.

[0186] Therefore, when the roller brush assembly rotates forward, a larger interference fit helps to effectively clean the surface of the roller brush. However, when rotating in the reverse direction, reducing the interference fit can avoid excessive scraping of the roller brush by the wiper, enabling the roller brush assembly to be in full contact with the liquid, achieving the purpose of rinsing, and thus maintaining the stability of the cleaning effect. This operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the roller brush assembly and automatically adjusting the position of the wiper assembly, intelligent interference fit management can be achieved, reducing manual intervention by users and improving the automation level and user experience of the device.

[0187] Optionally, the method further includes:

[0188] When the water pump assembly is in the on state, at least when it is detected that the height of the bottom liquid in the cleaning chamber is greater than a preset threshold, control the water pump assembly to switch to the off state.

[0189] In the embodiment of the present application, the preset threshold is a threshold preset in advance to prevent the liquid in the cleaning chamber from overflowing. When the liquid height in the cleaning chamber exceeds the preset threshold, continuing to operate the water pump assembly may cause the liquid to overflow. Therefore, by timely closing the water pump, it is possible to prevent the liquid from overflowing to the outside of the device, maintaining the cleanliness and dryness of the working environment. The embodiment of the present application does not specifically limit the size of the preset threshold, which can be set based on application scenario requirements and device capacity.

[0190] Exemplarily, during the soaking stage of the roller brush assembly, the height of the bottom liquid in the cleaning chamber can be monitored in real time. Then, when the water pump assembly is in the on state, when it is detected that the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, the water pump assembly is automatically turned off to prevent the liquid from overflowing, avoiding excessive liquid from entering sensitive components and preventing device damage and failures.

[0191] Therefore, when the water pump assembly is in the on state, the heating component can be controlled to be in the on state, and when it is detected that the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, the water pump assembly is automatically turned off to achieve thermal cleaning of the roller brush assembly. This comprehensive operation strategy can adapt to different cleaning requirements and operation modes. Whether it is increasing the interference fit, thermal cleaning, or liquid level management, the system can automatically adjust to ensure the best cleaning effect and device protection.

[0192] Optionally, the cleaning base station further includes a heating component, and the suction motor is also used to suck the heat of the heating component into the cleaning cavity to realize the flow of hot air in the cleaning cavity; the method further includes:

[0193] When it is detected that the water pump assembly is in the closed state and the suction motor is in the open state, control the heating component to be in the open state, so that the suction motor sucks the heat of the heating component into the cleaning cavity, heats the liquid in the cleaning cavity, and continues to perform thermal cleaning on the roller brush assembly.

[0194] It should be noted that in this application, the hot air generator can be shared with the device used for drying. However, for a cleaning system without a drying function, or when other components in the hot air generator are damaged and only the heating component can be used, the heat of the heating component can be sucked into the cleaning cavity by the suction motor to realize the flow of hot air in the cleaning cavity, playing the same role as the hot air generator.

[0195] Exemplarily, taking the case where there is a heating component in the cleaning system and the heating component is available as an example, when the cleaning system detects that the water pump assembly is in the closed state and the suction motor is in the open state, the heating component can be controlled to be in the open state, so that the suction motor sucks the heat of the heating component into the cleaning cavity, heats the liquid in the cleaning cavity, and continues to perform thermal cleaning on the roller brush assembly.

[0196] Therefore, when the hot air generator is damaged or the system has no drying function, the combination of the heating component and the suction motor can be used as an emergency alternative to ensure that the cleaning system can still operate normally and realize the thermal cleaning function. By providing an alternative hot air generation method, the reliability of the system can be improved, and the system downtime caused by a single component failure can be reduced. By intelligently controlling the working states of the heating component and the suction motor, the energy can be utilized efficiently, unnecessary energy consumption can be avoided, and the heating component and the suction motor are only turned on when needed, reducing energy waste. This comprehensive operation strategy can adapt to different cleaning requirements and operation modes. Whether it is thermal cleaning, drying or energy saving, the system can be automatically adjusted to ensure the best cleaning effect and equipment protection.

[0197] Exemplarily, this application also provides a self-cleaning method, which includes:

[0198] During the process of the cleaning device performing self-cleaning at the cleaning base station, it at least includes that when the hot air generator is in the open state, controlling one of the water pump assembly and the suction motor to be in the open state and the other to be in the closed state, and controlling the roller brush assembly to rotate forward and backward alternately;

[0199] Among them, when the water pump assembly is in the on state, it at least includes controlling the water pump assembly to switch to the off state when it is detected that the height of the bottom liquid in the cleaning cavity is greater than a preset threshold value.

[0200] In the embodiments of the present application, the definition of the preset threshold value is similar to that in the above embodiments, and will not be elaborated here. For details, reference can be made to the description of the above embodiments.

[0201] In some embodiments, during the self-cleaning process of the cleaning device at the cleaning base station, if it is detected that the hot air generator is in the on state, the water pump assembly can be controlled to be in the on state, the suction motor can be controlled to be in the off state, and the roller brush assembly can be controlled to rotate forward and backward alternately. At this time, it may be in the stage of soaking the roller brush assembly. Based on the hot air provided by the hot air generator, the liquid in the cleaning cavity is heated to achieve hot soaking.

[0202] In other embodiments, during the self-cleaning process of the cleaning device at the cleaning base station, if it is detected that the hot air generator is in the on state, the suction motor can be controlled to be in the on state, the water pump motor can be controlled to be in the off state, and the roller brush assembly can be controlled to rotate forward and backward alternately. At this time, it may be in the initial cleaning stage of the roller brush assembly or the pipeline cleaning stage. The suction motor pumps out the heated liquid in the cleaning cavity to achieve water replacement cleaning of the roller brush assembly or pipeline cleaning.

[0203] It should be noted that in the embodiments of the present application, when the hot air generator is in the on state, one of the water pump assembly and the suction motor is in the on state, the other is in the off state, and the roller brush assembly rotates forward and backward alternately, the corresponding stage is not specifically limited. The above are only illustrative examples.

[0204] Among them, when it is detected that the height of the bottom liquid in the cleaning cavity is greater than the preset threshold value, it is necessary to timely control the water pump assembly to switch to the off state to prevent liquid overflow, avoid excessive liquid entering sensitive components, and prevent equipment damage and failures.

[0205] Therefore, in the state where the hot air generator is turned on, the embodiments of the present application can use hot air to perform thermal cleaning on the roller brush assembly and the cleaning chamber, enhancing the cleaning effect. And by controlling the roller brush assembly to rotate forward and backward alternately, it can ensure that the surface of the roller brush is comprehensively cleaned, avoiding dead corners and omissions, and improving the cleaning effect. Among them, it is also necessary to monitor the liquid level in the cleaning chamber in real time. When it is detected that the liquid level is greater than the preset threshold, the water pump assembly is automatically turned off to prevent liquid overflow, keeping the working environment clean and dry. By intelligently controlling the working states of the water pump assembly and the suction motor, it is possible to efficiently utilize resources, avoid unnecessary energy consumption and waste of water resources, turn off the water pump when the liquid level reaches the preset threshold, reduce power consumption, and improve energy utilization efficiency. Therefore, through intelligent liquid level management and hot air control, the embodiments of the present application can avoid liquid from entering the electrical components while realizing thermal cleaning of the roller brush assembly, reducing the risks of electrical short circuits and mechanical failures, and enhancing the safety of the device.

[0206] Optionally, the cleaning device further includes a squeegee assembly; the squeegee assembly is in interference fit with the roller brush assembly; the method further includes:

[0207] In response to the self-cleaning instruction, control the squeegee assembly to move to the first position to increase the interference amount between the squeegee assembly and the roller brush assembly.

[0208] In the embodiments of the present application, the acquisition method of the self-cleaning instruction and the description of the interference amount are similar to those described in the above embodiments, and will not be elaborated here. For details, reference can be made to the description in the above embodiments.

[0209] Exemplarily, in response to the self-cleaning instruction, the cleaning system can control the squeegee assembly to move to the first position to increase the interference amount between the squeegee assembly and the roller brush assembly. And during the process of self-cleaning when the cleaning device is located in the cleaning base station, if it is detected that the hot air generator is in the on state, one of the water pump assembly and the suction motor can be controlled to be in the on state, and the other to be in the off state, and the roller brush assembly can be controlled to rotate forward and backward alternately to achieve thermal cleaning of the roller brush assembly.

[0210] During the above process, it is also necessary to monitor the height of the bottom liquid in the cleaning chamber in real time. When it is detected that the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, the water pump assembly is timely controlled to switch to the off state to prevent liquid overflow, keeping the working environment clean and dry.

[0211] Therefore, in the embodiments of the present application, by increasing the interference amount between the scraping strip assembly and the roller brush assembly, the pressure of the scraping strip on the roller brush is increased, so that the dirt and impurities on the surface of the roller brush can be more effectively scraped off, improving the cleaning effect. When the hot air generator is in the on state, hot air is used to perform hot cleaning on the roller brush assembly, further enhancing the cleaning effect, especially for removing stubborn stains on the surface of the roller brush. By controlling the roller brush assembly to rotate forward and backward alternately, it is ensured that the surface of the roller brush is comprehensively cleaned, avoiding dead corners and omissions, and improving the cleaning effect. By intelligently controlling the working states of the water pump assembly and the suction motor, efficient use of resources can be achieved. When the liquid level reaches the preset threshold, the water pump assembly is timely turned off, while improving the energy utilization efficiency, reasonably controlling the interference amount and liquid supply, reducing the wear of the scraping strip and the roller brush, and prolonging their service life.

[0212] Optionally, the method further includes:

[0213] When it is detected that the roller brush assembly rotates in the reverse direction, control the scraping strip assembly to move from the first position to the second position to reduce the interference amount between the scraping strip assembly and the roller brush assembly.

[0214] Exemplarily, when the roller brush assembly rotates forward and backward alternately, when it is detected that the roller brush assembly rotates in the forward direction, the scraping strip assembly can be controlled to move to the first position to increase the interference amount between the scraping strip assembly and the roller brush assembly. A larger interference amount helps to effectively clean the surface of the roller brush. When it is detected that the roller brush assembly rotates in the reverse direction, control the scraping strip assembly to move from the first position to the second position to reduce the interference amount between the scraping strip assembly and the roller brush assembly. Reducing the interference amount can avoid excessive scraping of the roller brush by the scraping strip, enabling the roller brush assembly to fully contact the liquid, achieving the purpose of rinsing, and thus maintaining the stability of the cleaning effect.

[0215] This mutually coordinated operation strategy reflects the intelligent control ability of the system. By real-time detecting the rotation direction of the roller brush assembly and automatically adjusting the position of the scraping strip assembly, intelligent interference amount management can be achieved, reducing manual intervention by users, and improving the automation level and user experience of the device.

[0216] Optionally, the cleaning base station further includes a heating component; the heating component is installed on the bottom wall of the cleaning cavity to heat the bottom liquid in the cleaning cavity. The method further includes:

[0217] When it is detected that the water pump assembly is in the on state, control the heating component to be in the on state, so that the heating component heats at least the bottom liquid in the cleaning cavity to perform hot cleaning on the roller brush assembly.

[0218] In the embodiments of the present application, the bottom liquid in the cleaning cavity can also be heated based on the heating component installed on the bottom wall of the cleaning cavity, and hot water is used to perform hot cleaning on the roller brush assembly.

[0219] Exemplarily, during the self-cleaning process of the cleaning device at the cleaning base station, if it is detected that the water pump assembly is in the on state, the heating assembly and / or the hot air generator can be controlled to be in the on state to perform thermal cleaning on the roller brush assembly.

[0220] In this way, by heating the cleaning liquid with the heating assembly and / or the hot air generator for soaking cleaning, the roller brush assembly can be cleaned with hot water or hot steam, further enhancing the cleaning effect. Moreover, the combination of hot water and hot air can better dissolve the dirt on the surface of the roller brush assembly and remove stubborn stains and grease on the roller surface, thereby improving the cleaning effect. The dual action of hot water and hot air can not only clean the surface of the roller brush but also deeply clean the gaps and small parts inside the roller brush to ensure thorough removal of dirt and bacteria and improve the overall cleaning effect. In addition, the cleaning system can automatically adjust the working modes of each component according to the real-time detected status. For example, the on / off of the heating assembly and / or the hot air generator can be flexibly controlled to ensure the best cleaning effect and equipment protection.

[0221] Optionally, when the water pump assembly is in the on state, at least when it is detected that the height of the bottom liquid in the cleaning chamber is greater than a preset threshold, controlling the water pump assembly to switch to the off state includes:

[0222] When it is detected that the water pump assembly is in the on state, the suction motor is in the off state, and the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, controlling the water pump assembly to switch from the on state to the off state so that the hot air generator delivers hot air into the cleaning chamber to heat the liquid in the cleaning chamber and perform thermal cleaning on the roller brush assembly.

[0223] Exemplarily, during the self-cleaning process of the cleaning device at the cleaning base station, if it is detected that the water pump assembly is in the on state, the suction motor is in the off state, and the height of the bottom liquid in the cleaning chamber is greater than the preset threshold, it is necessary to promptly control the water pump assembly to switch from the on state to the off state to prevent liquid overflow, avoid excessive liquid from entering sensitive components, and prevent equipment damage and failures.

[0224] Therefore, in the embodiments of the present application, after the water pump assembly switches from the on state to the off state, by delivering hot air into the cleaning chamber through the hot air generator, the cleaning liquid can be heated with hot air to further enhance the cleaning effect. Through intelligent liquid level management and component control, such as intelligently controlling the working state of the water pump assembly, efficient use of resources can be achieved, and unnecessary energy consumption and water resource waste can be avoided.

[0225] Optionally, the hot air generator includes a fan assembly and a heating assembly; the suction motor is further configured to suck the heat of the heating assembly into the cleaning cavity to achieve the flow of hot air in the cleaning cavity; when the hot air generator is in the on state, one of the water pump assembly and the suction motor is controlled to be in the on state, and the other is controlled to be in the off state, and the control of the roller brush assembly to rotate forward and backward alternately includes:

[0226] At least when the heating assembly is in the on state and the fan assembly is in the off state, the suction motor is controlled to be in the on state, the water pump assembly is controlled to be in the off state, and the roller brush assembly is controlled to rotate forward and backward alternately, so that the suction motor sucks the heat of the heating assembly into the cleaning cavity, heats the liquid in the cleaning cavity, and performs thermal cleaning on the roller brush assembly.

[0227] It should be noted that if the fan assembly in the hot air generator is damaged, the heat of the heating assembly can be sucked into the cleaning cavity by the suction motor to achieve the flow of hot air in the cleaning cavity, replacing the function of the hot air generator. Alternatively, based on application scenarios or user requirements, such as energy consumption requirements, the heating assembly can be intelligently controlled to be in the on state or the hot air generator can be in the on state.

[0228] Wherein, when the heating assembly is in the on state, in addition to providing suction force for the extraction of the liquid in the cleaning cavity, the suction motor is also used to suck the heat of the heating assembly into the cleaning cavity to achieve the flow of hot air in the cleaning cavity; when the hot air generator is in the on state, the suction motor is only used to provide suction force for the extraction of the liquid in the cleaning cavity.

[0229] Exemplarily, during the self-cleaning process of the cleaning device at the cleaning base station, if it is detected that the heating assembly is in the on state and the fan assembly is in the off state, the suction motor can be controlled to be in the on state, the water pump assembly can be controlled to be in the off state, and the roller brush assembly can be controlled to rotate forward and backward alternately, so that the suction motor sucks the heat of the heating assembly into the cleaning cavity, replacing the function of the hot air generator, and heating the liquid in the cleaning cavity to perform thermal cleaning on the roller brush assembly.

[0230] In this way, the heat of the heating assembly is sucked into the cleaning cavity by the suction motor to form a hot air flow to heat the cleaning liquid, and the roller brush assembly is cleaned with hot water or hot steam, effectively dissolving and removing stubborn stains on the surface and inside of the roller brush assembly, further enhancing the cleaning effect. By intelligently controlling the working states of the heating assembly and the suction motor, energy can be efficiently utilized, unnecessary energy consumption can be avoided, and the combination of the heating assembly and the suction motor can be used as an emergency alternative to ensure that the cleaning system can still operate normally and achieve the thermal cleaning function. By providing an alternative hot air generation method, the reliability of the system can be improved, and the system downtime caused by a single component failure can be reduced.

[0234] When it is detected that the rotation direction of the roller brush assembly changes, control the position of the occlusion mechanism to change the air flow direction of the air outlet of the base air duct.

[0235] It should be noted that the implementation manners and effects of the above two optional examples are similar to those of the above embodiments. For details, please refer to the description of the above embodiments and will not be elaborated here.

[0236] Optionally, the method further includes:

[0237] When it is detected that the water pump assembly is in the off state, the suction motor is in the on state, and the hot air generator is switched from the off state to the on state, control the hot air generator to be in the on state for at least some time periods.

[0238] In the embodiment of the present application, during the self-cleaning process, the hot air generator can be started at at least one stage, and hot air is blown towards the roller brush assembly and the liquid in the cleaning chamber is heated to achieve thermal cleaning of the roller brush assembly.

[0239] Exemplarily, taking the self-cleaning stage as 1 min 45 s as an example, the roller brush assembly is in the soaking stage from 0 to 15 s, in the preliminary cleaning stage of the roller brush assembly from 15 to 26 s; in the soaking stage of the roller brush assembly from 26 to 40 s; in the pipeline cleaning stage from 40 to 55 s; in the deep cleaning stage from 55 to 105 s; wherein, in the preliminary cleaning stage, the pipeline cleaning stage and the deep cleaning stage, the hot air generator can be started. Optionally, the hot air generator can also be started at any time period in the preliminary cleaning stage, the pipeline cleaning stage and the deep cleaning stage. The embodiment of the present application does not specifically limit the partial time periods for starting the hot air generator.

[0240] Optionally, during the process that the cleaning device is in the preliminary cleaning stage, at least some time periods of the hot air generator are in the on state; wherein, the water pump assembly is in the off state, the suction motor is in the on state, and the roller brush assembly rotates forward, for example, the hot air generator is started from 15 to 25 s.

[0241] Optionally, during the pipeline cleaning stage of the cleaning device, at least part of the hot air generator is in the on state, wherein the roller brush assembly rotates forward, the water pump assembly is in the off state, and the suction motor is in the on state.

[0242] It can be understood that the suction motor can suck away the hot air through the sewage suction channel. The hot air can also melt the oily stains adhering to the wall of the sewage suction channel, and the cleaning liquid can be superimposed for flushing and cleaning the sewage suction channel, thereby improving the self-cleaning efficiency.

[0243] Optionally, when the roller brush assembly rotates forward, the water pump assembly is in the off state, the suction motor is in the off state, and the hot air generator is in the on state, after running for the first duration, control the suction motor to switch from the off state to the on state; continue to control the roller brush assembly to rotate forward, the water pump assembly is in the off state, the suction motor is in the on state, and the hot air generator is in the on state, and run for the second duration, such as the first duration corresponding to 40 - 42 s and the second duration corresponding to 40 - 45 s.

[0244] It should be noted that during the above pipeline cleaning process, the above process can be repeated multiple times, and the embodiments of the present application do not make specific limitations on this.

[0245] Optionally, during the deep cleaning stage of the cleaning device, the hot air generator is continuously in the on state, wherein the roller brush assembly rotates forward and backward alternately, and the suction motor is in the on state.

[0246] Optionally, when the water pump assembly is in the off state, the suction motor is in the off state, and the hot air generator is in the on state, control the roller brush assembly to rotate forward and backward alternately within the third duration; the forward and backward alternating rotation state includes forward rotation, reverse rotation, and stop; after the third duration ends, control the water pump assembly to switch from the off state to the on state, and control the roller brush assembly to rotate forward and backward alternately within the fourth duration; after the fourth duration ends, control the water pump assembly to switch from the on state to the off state, and control the roller brush assembly to rotate forward within the fifth duration, such as the third duration corresponding to 55 - 77 s, the fourth duration corresponding to 77 - 103 s, and the fifth duration corresponding to 103 - 105 s.

[0247] Among them, when the roller brush assembly rotates forward and the suction motor is in the off state, the roller brush assembly can rotate forward at 150 r / min; when the roller brush assembly rotates backward and the suction motor is in the on state, the roller brush assembly can rotate backward at 150 r / min, and the suction motor works at a power of 150 W; when the roller brush assembly rotates forward and the suction motor is in the on state, the roller brush assembly can rotate forward at 450 r / min, and the suction motor works at a power of 150 W.

[0248] Therefore, in the embodiment of the present application, by turning on the hot air generator in some time periods, hot air can be used to further clean and disinfect the roller brush assembly, enhancing the cleaning effect. By turning on the suction motor, the hot air can be evenly distributed in the cleaning cavity to ensure that all components can be fully cleaned. Furthermore, by intelligently controlling the opening time period of the hot air generator, efficient use of energy can be achieved, unnecessary energy consumption can be avoided, the hot air generator is only turned on when needed, energy waste is reduced, and the above comprehensive operation strategy can adapt to different cleaning requirements and operation modes, improving the flexibility of hot cleaning.

[0249] Optionally, the method further includes:

[0250] During the self-cleaning process of the cleaning device at the cleaning base station, controlling the cleaning base station to charge the cleaning device.

[0251] Charging the cleaning device during the self-cleaning process ensures that the device has sufficient power to continue performing other cleaning tasks after completing self-cleaning, extending the working time of the device. And by charging during the self-cleaning process, the downtime of the device due to insufficient power can be reduced. Since self-cleaning and charging are carried out simultaneously, the time when the device stays at the base station is fully utilized, improving the time utilization rate, avoiding occupying extra time for charging alone, and by carrying out self-cleaning and charging simultaneously, the working state of the device can be quickly restored, improving the overall cleaning efficiency, so that the user does not need to separately arrange the charging time of the cleaning device, and the system automatically completes charging during the self-cleaning process, simplifying the operation process and improving the user experience.

[0252] Optionally, the method further includes:

[0253] After the self-cleaning of the cleaning device at the cleaning base station ends, controlling the water pump assembly to be in the off state, and both the hot air generator and the suction motor to be in the on state to dry the roller brush assembly.

[0254] In the embodiments of the present application, the hot air generator and the suction motor can also be used to dry the roller brush assembly. Among them, the hot air generator provides hot air, and the suction motor promotes air flow, which can quickly dry the roller brush assembly and other components in the cleaning cavity, prevent moisture residue, and through the action of the suction motor, the hot air can be evenly distributed in the cleaning cavity to ensure that all components can be fully dried and avoid local dampness.

[0255] In this way, by drying the roller brush assembly, long-term retention of moisture can be prevented, the growth of mold and bacteria can be inhibited, the hygiene and cleanliness of the device can be maintained, which helps to keep the hygiene of the roller brush assembly and the cleaning cavity, reduce the risk of odor and bacteria transmission. Through the dual action of the hot air generator and the suction motor, the function of rapid drying can be achieved, preventing long-term retention of moisture inside the device, thereby extending the service life of the device.

[0256] Exemplarily, Figure 6 is a schematic flowchart of another self-cleaning method provided by the embodiments of the present application. As Figure 6 shown, the self-cleaning method includes:

[0257] S601. In response to the self-cleaning instruction, control the scraper assembly to move to the first position to increase the interference amount between the scraper assembly and the roller brush assembly.

[0258] S602. During the process of the cleaning device performing self-cleaning at the cleaning base station, at least when the hot air generator is in the on state, control one of the water pump assembly and the suction motor to be in the on state and the other to be in the off state, and control the roller brush assembly to rotate forward and backward alternately.

[0259] It should be noted that the acquisition method of the self-cleaning instruction and the description of the interference amount are similar to those described in the above embodiments, and will not be elaborated here. For details, reference can be made to the description in the above embodiments.

[0260] It should also be noted that S602 is similar to the description of the above embodiments, which is the implementation method of the hot air generator providing hot air for the cleaning cavity, heating the liquid in the cleaning cavity and the roller brush assembly. For details, reference can be made to the description of the above embodiments. In the embodiments of the present application, S601 and S602 are the implementation methods of providing hot air and the scraper assembly cooperating with each other for hot cleaning.

[0261] Therefore, the present application can control the interference amount between the squeegee assembly and the roller brush assembly according to the working mode of the cleaning device, so as to increase the pressure of the squeegee on the roller brush, making the pressure between the squeegee and the roller brush greater than that in the cleaning state. In addition, the present application makes full use of the function of the hot air generator, which can also be turned on during the self-cleaning process, and then uses hot air to heat the cleaning liquid or directly heat the surface of the roller brush assembly, so as to more effectively heat and dissolve stubborn stains. Coupled with the interference fit with the squeegee assembly, it is possible to squeeze or scrape out the heated and dissolved dirt from the inside and even the depth of the roller brush in the first time, ensuring the cleanliness of the roller brush assembly.

[0262] During the self-cleaning process, by controlling one of the water pump assembly and the suction motor to be turned on and the other to be turned off, and controlling the roller brush assembly to rotate forward and backward alternately, each part of the roller brush assembly can be cleaned more comprehensively, preventing the generation of dead corners. And by alternately turning on the water pump assembly and the suction motor, the usage of water and electricity can be effectively controlled, avoiding waste of resources and achieving the purpose of energy conservation and environmental protection. By rotating the roller brush assembly forward and backward alternately, the roller brush can be evenly worn, avoiding the imbalance and premature damage of the roller brush caused by one-way wear. In the present application, since the hot air generator can be turned on to heat the liquid and the roller brush assembly in the cleaning cavity, therefore, combined with the operation of the water pump assembly or the suction motor, efficient cleaning of the surface and the root of the roller brush assembly can be achieved, and the above process is automated. Through the above automated self-cleaning process, there is no need for manual operation by the user, which can also improve the user experience and convenience.
