Description

Technical Field

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

[0002] Floor scrubbers and other wet cleaning systems are core equipment for cleaning surfaces in homes and commercial spaces, integrating vacuuming, scrubbing, and self-cleaning. After cleaning the surface, the scrubber's roller brush and suction pipes become covered in dirt and need to be returned to its base station for cleaning and charging. During self-cleaning, the base station's cleaning tank, the scrubber's main fan, water pump, and heating elements work together to automatically clean the roller brush.

[0003] In addition to cleaning the roller brush, the suction pipe of the floor scrubber also needs to be cleaned during the self-cleaning process to prevent secondary pollution, as some dirt adheres to the inner wall of the pipe due to the solid-liquid separation of debris during the cleaning process. To address this, existing technologies primarily rely on the main fan to pulse-like power switching between a few fixed speeds to introduce liquid from the cleaning tank into the suction pipe, simulating a "surge" phenomenon to repeatedly flush the inner wall of the pipe. For example, the operating logic is as follows: after self-cleaning begins, the main fan immediately increases its power from level 0 to level P4 and runs stably for a period of time. Then, the power drops sharply to level 0, and then quickly increases to a higher power P5 and maintains that level for a period of time, repeating this cycle until self-cleaning ends.

[0004] However, the frequent start-stop and power surges of the fan generate significant mechanical vibration and aerodynamic noise. Especially during the continuous switching between low and high speeds, the noise fluctuates greatly and repeats itself, causing significant auditory disturbance to users and seriously affecting their user experience. Summary of the Invention

[0005] This application provides a self-cleaning method, apparatus, and cleaning system for cleaning equipment. By setting a stepped slow-start sequence for the main fan in the first cleaning mode, with the power increasing sequentially in the first, second, and third stages and the second duration not exceeding one-fifth of the first duration, the power surge and noise fluctuation during the main fan operation are effectively reduced, significantly improving the smoothness of the self-cleaning process and the user's auditory experience.

[0006] In a first aspect, this application provides a self-cleaning method for cleaning equipment, applied to a cleaning system. The cleaning system includes cleaning equipment and a cleaning base station. The cleaning equipment includes a roller brush and a main fan for generating suction. When the roller brush is located in the cleaning tank of the cleaning base station, the cleaning equipment performs a self-cleaning action. The cleaning equipment has a first cleaning mode, and the method includes:

[0007] In response to the self-cleaning command, the cleaning equipment is controlled to enter the first cleaning mode;

[0008] In the first cleaning mode, the cleaning equipment performs at least the following steps:

[0009] Control the main fan to operate at the first power for a first duration;

[0010] After the main fan operates at the first power for a first duration, control the main fan to operate at the second power for a second duration;

[0011] After the main fan has been running at the second power for a second period of time, control the main fan to run at the third power.

[0012] Among them, the third power is greater than the second power, the second power is greater than the first power, and the second duration does not exceed one-fifth of the first duration.

[0013] Compared to existing main fans that often start directly to high power or experience frequent start-stop cycles and abrupt power changes, leading to severe airflow impacts and mechanical vibrations and fluctuating noise, this application addresses the problem by setting a progressively increasing power sequence of first (low power), second (medium power), and third (high power), with each power level operating for a specific duration. This makes the main fan speed and airflow establishment process smooth and continuous, avoiding the impact noise caused by abrupt power changes. Furthermore, by establishing a clear duration relationship—the second power duration not exceeding 1 / 5 of the first power duration—the transition phase to the second power is very short. Thus, a smooth start and initial airflow guidance are achieved by operating at the first power for a longer duration, followed by a rapid transition to the third power with a short second power stage. This ensures a smooth transition and avoids prolonged lingering in the second power segment, preventing the generation of new, continuous noise sources. The overall noise curve is characterized by a "rapid and smooth ascent to high power," rather than fluctuating back and forth between multiple power levels. Furthermore, this application clarifies that the first cleaning mode is a step-by-step power increase process, rather than the repeated start-stop or high-low power cyclic switching process that may exist in the prior art, thereby reducing frequent high-low power switching and effectively avoiding the intermittent and repetitive noise interference generated in the prior art.

[0014] Therefore, this application effectively suppresses the mechanical vibration and aerodynamic noise caused by sudden changes in the main fan during the power increase process by using refined power timing control with low power start-up, short transition, and step-by-step ramp-up to high power. This greatly reduces interference to users and significantly improves the user experience of the cleaning equipment during the self-cleaning process.

[0015] Optionally, the cleaning equipment also includes a suction pipe. When the main fan is running at a first power for a first duration, some of the liquid in the cleaning tank is drawn to the inner wall of the suction pipe and remains in the suction pipe, so that some of the liquid cleans the suction pipe.

[0016] In this way, by utilizing the principle of fluid dynamics balance, a small amount of liquid drawn during the first power operation phase is used to wet and preliminarily rinse the inner wall of the suction pipe without the need for additional cleaning equipment or complex control. This helps to soften or remove dried stains, hair, or particles adhering to the inner wall of the suction pipe, preventing dirt from accumulating inside the pipe and reducing the risk of blockages, odors, or bacterial growth caused by long-term dirt residue in the pipe, thus improving the overall cleanliness and ease of maintenance of the cleaning system.

[0017] Optionally, the method also includes:

[0018] After the main fan operates at the third power for a third duration, control the main fan to operate at the second power for a second duration;

[0019] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the first power for a fourth duration.

[0020] In this way, this application achieves a smooth shutdown of the main fan by setting a stepped power reduction process of "high power - medium power - low power". Furthermore, by incorporating a buffer phase during power reduction, it avoids the vibration and noise impact that might occur when shutting down abruptly from the third power level or dropping abruptly to the first power level, thus making the self-cleaning process more stable and quiet. Simultaneously, during the first power operation phase, a secondary cleaning of the inner wall of the suction pipe is performed, further optimizing the cleaning effect and contributing to a more thorough self-cleaning process.

[0021] Optionally, the cleaning equipment may also include a water pump assembly, and the method may also include:

[0022] During the operation of the main fan, the water pump assembly is kept in the on state.

[0023] In this way, during the self-cleaning process, while the main fan is operating in the first cleaning mode, the water pump assembly can be simultaneously kept on, working in tandem with the suction action of the main fan. This ensures a continuous supply of cleaning water or cleaning solution to the cleaning tank, maintaining an effective cleaning liquid level and flow within the tank. This helps the roller brush to be fully soaked and rinsed, improving the efficiency of dissolving and removing dirt from the roller brush surface. Simultaneously, in conjunction with the suction action of the main fan, a synergistic cleaning effect of rinsing and removing dirt is achieved, thereby enhancing the overall cleaning effect and efficiency of the self-cleaning process.

[0024] Optionally, the method also includes:

[0025] During the operation of the main fan at the first power, the water pump assembly is controlled to increase the liquid output to the first liquid output; the first liquid output is greater than the second liquid output; the second liquid output is the liquid output corresponding to the water pump assembly during the operation of the main fan at the second power and / or the third power.

[0026] By increasing the water pump output during the initial power operation phase of the main blower, more liquid can be injected into the cleaning tank during periods of relatively weak suction. This ensures thorough soaking and wetting of the roller brush and effective rinsing of the inner walls of the suction pipe. This helps soften and remove stubborn stains, dilutes highly concentrated wastewater, thereby improving overall cleaning efficiency and preventing problems such as dry running of the pump or incomplete cleaning due to insufficient liquid.

[0027] Optionally, the cleaning equipment also has a second cleaning mode, and the method further includes:

[0028] After the first cleaning mode ends, control the cleaning equipment to enter the second cleaning mode;

[0029] In the second cleaning mode, the water pump assembly is switched from the on state to the off state.

[0030] Therefore, by entering a second cleaning mode that stops supplying liquid after the first cleaning mode, the continuous supply of liquid can be cut off. This helps reduce unnecessary liquid residue and accumulation in the cleaning tank during subsequent spin-drying or pure suction stages, thereby more efficiently utilizing the suction power of the main fan to dehydrate or remove residual liquid from the roller brush and pipelines, improving self-cleaning efficiency. Furthermore, the water pump assembly is an energy-consuming component. Turning it off promptly in the second cleaning mode, when no cleaning liquid supply is needed, eliminates unnecessary energy consumption and avoids excessive consumption of cleaning liquid.

[0031] Optionally, the method also includes:

[0032] In the second cleaning mode, the cleaning equipment performs at least the following steps:

[0033] The main fan was controlled to operate at its first power for a fifth period of time.

[0034] After the main fan operates at the first power for a fifth duration, the main fan is controlled to operate at the second power for a second duration; the fifth duration shall not exceed one-tenth of the second duration.

[0035] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the third power for a sixth duration.

[0036] Thus, in the second cleaning mode, the stepped power control method for noise reduction is continued. A brief initial power operation helps to gently guide the initial airflow to clean the suction pipe and roller brush area when no new liquid is supplied. Then, based on the second power, the operation gradually increases to the third power and continues, avoiding violent splashing or impact noise caused by a sudden power increase. Simultaneously, considering the characteristics of the second cleaning mode—low water content and a focus on removing residual moisture—the duration of each power stage is optimized. While ensuring necessary cleaning and efficient suction of the suction pipe, the overall energy efficiency and time efficiency of the second cleaning mode are improved, and noise performance is optimized.

[0037] Optionally, the method also includes:

[0038] After the main fan operates at the third power for a sixth time, the main fan is controlled to operate at the second power for a second time.

[0039] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the first power for a seventh duration.

[0040] Thus, in the second cleaning mode, this application can also achieve a smooth shutdown of the main fan by setting a stepped power reduction process of "high power - medium power - low power". This avoids the sudden stop of airflow, vibration, and noise impact that may occur when shutting down directly from high power, improving the stability and quietness of the cleaning equipment during the shutdown phase. At the same time, during the first power operation phase, residual moisture in the suction pipe and roller brush area can be cleaned, further optimizing the self-cleaning effect and helping the cleaning equipment enter a more stable state after the second cleaning mode ends.

[0041] Optionally, the method also includes:

[0042] During the operation of the main fan, the control roller rotates based on the first direction.

[0043] In this way, during the suction process of the main fan, by controlling the continuous rotation of the roller brush in the first direction, the brush bristles and the cleaning tank structure can generate relative movement and friction, thereby more effectively removing stains and hair attached to the surface of the roller brush. The centrifugal force generated by the rotation also helps to throw the sewage and impurities inside the roller brush outward. Combined with the suction force of the main fan, a synergistic cleaning effect of mechanical peeling and fluid suction is formed, significantly improving the cleaning efficiency and effect of the roller brush.

[0044] Optionally, the cleaning equipment also has a second cleaning mode and a third cleaning mode, and the method further includes:

[0045] After the first or second cleaning mode ends, control the cleaning equipment to enter the third cleaning mode;

[0046] In the third cleaning mode, the cleaning equipment performs at least the following steps:

[0047] The control roller is kept in a stopped state, and the main fan is controlled to run at the fourth power for the eighth time.

[0048] After the main fan operates at the fourth power for eight hours, the control brush rotates in the second direction, and the main fan operates at the fifth power for nine hours.

[0049] Among them, the second direction is opposite to the first direction, and the fifth power is greater than the fourth power.

[0050] Thus, by introducing a third cleaning mode, a deep cleaning and dehydration process is specifically performed on the roller brush after completing the first or second cleaning mode. By setting the roller brush to operate at a lower fourth power when it is not running, a preliminary, gentle airflow is used to loosen residual fine dirt on the surface and crevices of the roller brush, facilitating direction switching and preventing damage to the motor. Subsequently, the roller brush is controlled to rotate in the opposite second direction, while the main fan is increased to a fifth power. This reverse rotation changes the direction of force on the bristles, more effectively dislodging any dirt or wastewater that may have remained or become embedded during forward rotation, and then promptly removing it with enhanced suction. This combination of reverse rotation and powerful suction significantly improves the thoroughness and reliability of the self-cleaning process.

[0051] Optionally, the fourth power is greater than the first power.

[0052] By introducing an intermediate fourth power level into the main fan's power ramp-up path, a smoother and more controllable two-stage transition from the first to the fifth power level is achieved. The jump from the first to the fifth power level is a large-scale power change; this is broken down into two smaller power ramp-up steps: from the first to the fourth power level, and then from the fourth to the fifth power level. This reduces the power increment at each step, resulting in more gradual changes in the main fan speed and airflow intensity. This effectively reduces torque shocks, mechanical vibrations, and airflow turbulence caused by sudden power changes, leading to smoother operation. Furthermore, the design of the fourth power level being greater than the first power level provides the control algorithm with more precise adjustment tools. This allows the cleaning system to manage the power ramp-up rate more accurately, ensuring that the main fan and drive circuitry operate within safe electrical and thermal load ranges, improving the cleaning system's control robustness under complex conditions and long-term operational reliability. Moreover, the smoother power ramp-up process means that the intensity and frequency changes of the main fan noise are also more gradual. This helps avoid large transient noises or unpleasant pitch fluctuations, making the overall noise sound more continuous and stable, improving the user's auditory experience.

[0053] Optionally, the cleaning equipment also has a fourth cleaning mode, which includes the following methods:

[0054] After the third cleaning mode ends, control the cleaning equipment to enter the fourth cleaning mode;

[0055] In the fourth cleaning mode, the cleaning equipment performs at least the following steps:

[0056] Control the roller brush to be in a stopped state, and control the main fan to run at the sixth power for the eighth time;

[0057] After the main fan operates at the sixth power for eight hours, the control brush rotates based on the first direction, and the main fan operates at the fifth power for nine hours.

[0058] The sixth power is less than the fourth power.

[0059] Thus, this application introduces a fourth cleaning mode. After the third cleaning mode, the rotation direction of the roller brush is switched again and the power of the main fan is adjusted to form a "reset cleaning" stage. This stage involves operating the main fan at a lower sixth power while the roller brush is stopped, allowing for a gentle initial blowing and tidying of the roller brush after the reverse strong cleaning. Subsequently, the roller brush is controlled to rotate in the initial first direction, and with the help of a stronger fifth power suction, the bristles are restored to their normal working direction. At the same time, any loosened residue or wastewater during the reset process is removed, and the airflow is combed through the roller brush to ensure that it is clean, fluffy, and correctly oriented in a standby state, ready for the next cleaning operation.

[0060] Optionally, the sixth power is equal to the first power.

[0061] In this way, after the main fan has operated at the fourth power for eight hours, the power can be reduced to a verified and stable first power. This step acts as a "reset," establishing a lower starting point for the main fan's subsequent power ramp-up. Further, starting from the lower first power, the power can be gradually increased to the fifth power. This process can reuse or draw upon the verified, gradual power ramp-up strategy (e.g., step-by-step increase) from the first cleaning mode. This ensures that even when switching between different cleaning modes, the main fan's transition to high-power operation is smooth, controlled, and low-noise. Furthermore, this method of first reducing to the first power and then increasing to the fifth power significantly reduces the amplitude and rate of power change near the mode switching point compared to directly switching or jumping from the fourth power to the fifth power. This effectively suppresses potential electrical stress, mechanical vibration, and sudden changes in airflow noise that may occur during mode switching, resulting in smoother transitions between different modes in the self-cleaning process and more stable overall operation.

[0062] Secondly, this application provides a self-cleaning device for cleaning equipment, applied to a cleaning system. The cleaning system includes cleaning equipment and a cleaning base station. The cleaning equipment includes a roller brush and a main fan for generating suction. When the roller brush is located in the cleaning tank of the cleaning base station, the cleaning equipment performs a self-cleaning action. The cleaning equipment has a first cleaning mode, and the device includes:

[0063] The first control module is used to control the cleaning equipment to enter the first cleaning mode in response to the self-cleaning command;

[0064] The second control module is used to control the cleaning equipment to perform at least the following steps in the first cleaning mode:

[0065] Control the main fan to operate at the first power for a first duration;

[0066] After the main fan operates at the first power for a first duration, control the main fan to operate at the second power for a second duration;

[0067] After the main fan has been running at the second power for a second period of time, control the main fan to run at the third power.

[0068] Among them, the third power is greater than the second power, the second power is greater than the first power, and the second duration does not exceed one-fifth of the first duration.

[0069] Thirdly, this application provides a cleaning system, which includes a cleaning device and a cleaning base station. The cleaning device includes a roller brush and a main fan for generating suction. When the roller brush is located in the cleaning tank of the cleaning base station, the cleaning device performs a self-cleaning action. The cleaning device has a first cleaning mode, and the cleaning system is used to perform the method as described in any of the first aspects.

[0070] The self-cleaning method, apparatus, and system for cleaning equipment provided in this application divide the power of the main fan during the self-cleaning process into at least three power stages: a first power (low power), a second power (transitional power), and a third power (high power). A second duration of operation at the second power is inserted between the main fan's transition from the first power to the third power as a transition phase, avoiding a direct switch from low to high power and thus reducing vibration and noise impact caused by sudden power changes. Furthermore, this second duration does not exceed one-fifth of the first duration of operation at the first power, ensuring a smooth power change and suppressing abrupt noise fluctuations. In this way, in self-cleaning mode, the main fan first operates at a lower first power for a first duration, completing the initial cleaning of the suction pipe; then, it briefly operates at the intermediate second power for a second duration as a buffer phase for power increases, preventing a direct jump to high power before further increasing to the higher third power, achieving efficient sewage suction. This gradual increase in power, rather than instantaneous switching, ensures a smooth transition in the main fan's operating state, reducing repeated noise fluctuations and effectively mitigating vibration and noise abrupt changes during fan operation, thereby improving the user's auditory experience.

[0078] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0079] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0080] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, "first power" and "second power" are only used to distinguish different power levels and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0081] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0082] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0083] Floor scrubbers are typically equipped with a cleaning base station, which functions to replenish water to the scrubber, self-clean the roller brush, and dry the roller brush. The roller brush self-cleaning function aims to remove residual dirt, including wastewater and solid debris, from the brush surface. However, the self-cleaning process is often accompanied by relatively high operating noise, which contradicts the trend of floor scrubbers becoming more high-end and quieter. Therefore, reducing noise during the self-cleaning phase has become a key requirement in the definition of floor scrubber products.

[0084] Furthermore, after completing a cleaning task, existing floor scrubbers often leave debris (such as hair and lint) in the suction pipe between the brush end and the wastewater tank, which is difficult to remove completely. These residues may still clog the pipe during the self-cleaning process, leading to problems such as decreased suction performance, odors, or unusual noises.

[0085] In existing technologies, cleaning of suction pipes mainly relies on the main fan to pulse-like power switching between a few fixed gears to introduce the liquid from the cleaning tank into the suction pipe to simulate a "surge" phenomenon and repeatedly flush the inner wall of the pipe. For example, its operating logic is as follows: after self-cleaning begins, the main fan immediately increases its power from gear 0 to gear P4 and runs stably for a period of time. Then, the power drops sharply to gear 0 and then quickly increases to a higher gear P5 and maintains it for a period of time, repeating the cycle until self-cleaning ends.

[0086] However, the frequent start-stop and power surges of the fan generate significant mechanical vibration and aerodynamic noise. Especially during the continuous switching between low and high speeds, the noise fluctuates greatly and repeats itself, causing significant auditory disturbance to users and seriously affecting their user experience.

[0087] To address the aforementioned issues, this application provides a self-cleaning method for cleaning equipment. By dividing the power of the main fan during the self-cleaning process into at least three power stages: a first power (low power), a second power (transitional power), and a third power (high power), a second duration of operation at the second power is inserted as a transition phase between the main fan's increase from the first power to the third power. This avoids a direct switch from low to high power, thereby reducing vibration and noise impact caused by sudden power changes. Furthermore, this second duration does not exceed one-fifth of the first duration of operation at the first power, ensuring a smooth power change and suppressing abrupt noise fluctuations. Thus, in self-cleaning mode, the main fan first operates at a lower first power for a first duration, completing the initial cleaning of the suction pipe; then, it briefly operates at the intermediate second power for a second duration as a buffer phase for power increases, preventing a direct jump to high power before further increasing to the higher third power, achieving efficient sewage suction. This gradual increase in power, rather than instantaneous switching, ensures a smooth transition in the main fan's operating state, reducing repeated noise fluctuations and effectively mitigating vibration and noise abrupt changes during fan operation, thereby improving the user's auditory experience.

[0088] Optionally, the self-cleaning method for cleaning equipment provided in this application can be applied to a cleaning system, for example... Figure 1 This is a partial structural diagram of a cleaning system provided in an embodiment of this application, as shown below. Figure 1 As shown, the cleaning system 300 includes a cleaning device 200 and a cleaning base station 100. The cleaning device 200 includes a roller brush 201 and a main fan 202 for generating suction force. When the roller brush 201 is located in the cleaning tank 101 of the cleaning base station 100, the cleaning device 200 performs a self-cleaning action. The cleaning device 200 has a first cleaning mode, which is a preset self-cleaning operation mode, mainly used to clean the roller brush 201 and pump the sewage in the cleaning tank 101 to the sewage tank.

[0089] Optionally, the cleaning equipment 200 also includes a suction pipe (not shown in the figure). The throat is a part of the suction pipe, which is usually located between the suction port and the sewage tank inlet. Sewage enters the throat through the suction port, and its constriction design accelerates the gas-liquid mixing flow. Then, it finally enters the sewage tank through the suction pipe, completing the solid-liquid separation and sewage collection.

[0090] Optionally, the cleaning device 200 may also include a water pump assembly (not shown) for supplying cleaning fluid, such as water or cleaning agent solution, to the cleaning tank 101 and / or the roller brush 201.

[0091] Based on the above structural design of the cleaning system 300, the cleaning system 300 can effectively self-clean the roller brush 201 and the suction pipe. For example, Figure 2This is a schematic diagram of an application scenario provided in an embodiment of this application, such as... Figure 2 As shown, taking the cleaning equipment 200 as a floor scrubber as an example, after the floor scrubber completes the cleaning task in the living room area and returns to the cleaning base station 100, it can automatically or through user commands trigger a self-cleaning command to control the floor scrubber to enter the first cleaning mode.

[0092] The first cleaning mode of a floor scrubber includes at least the following three stages:

[0093] Phase 1: Control the main fan to run at its lowest power (low power) for the first duration. Phase 1 can be used for initial wetting and cleaning of the internal suction pipes of the main unit.

[0094] Phase Two: After the main fan operates at its first power for a first duration, it is switched to its second power (medium power, higher than the first power) for a second duration. This second phase is a brief transition period designed to smoothly increase the fan power and avoid the noise and vibration impact of a direct switch to high power. The second duration should not exceed one-fifth of the first duration.

[0095] Phase 3: After the main blower has been running at the second power for a second period of time, the main blower is switched to the third power (high power, higher than the second power). In the third phase, the sewage in the cleaning tank is forcefully pumped into the sewage tank with high suction force, completing the main cleaning and sewage recycling process.

[0096] Optionally, the above three stages can be executed repeatedly. This application embodiment does not specifically limit the number of times the stages are executed repeatedly, but can determine the number of times based on user needs, the degree of dirt on the roller brush, and the degree of dirt on the suction pipe.

[0097] In this way, through the above-mentioned step-by-step power control of "low power - medium power - high power", the noise and vibration performance of the floor scrubber is optimized while ensuring effective cleaning and suction, thus improving the user experience.

[0098] It should be noted that the embodiments of this application do not specifically limit the type of cleaning equipment. In addition to floor scrubbers, the cleaning equipment can also be other intelligent cleaning equipment with dual functions of roller brush cleaning and suction cleaning, and is also equipped with a cleaning base station with self-cleaning function.

[0099] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0100] For example, Figure 3This is a schematic flowchart illustrating a self-cleaning method for a cleaning device provided in an embodiment of this application. The self-cleaning method for the cleaning device is applied to... Figure 1 In the cleaning system with the structure shown, such as Figure 3 As shown, the self-cleaning method of this cleaning equipment includes the following steps:

[0101] S301, In response to the self-cleaning command, control the cleaning equipment to enter the first cleaning mode.

[0102] In this embodiment, the self-cleaning instruction can refer to a trigger signal used to instruct the cleaning device to begin its self-cleaning procedure. This self-cleaning instruction can be manually triggered by the user (e.g., by pressing a button on the cleaning base station or cleaning device), or it can be automatically generated by the cleaning device or cleaning base station when specific conditions are met (e.g., detecting that the cleaning device has been returned to the cleaning base station). This embodiment does not specifically limit the triggering conditions for the self-cleaning instruction.

[0103] Optionally, the first cleaning mode may include a cleaning mode for the roller brush and suction pipe and a suction mode for the wastewater in the cleaning tank.

[0104] S302. In the first cleaning mode, the cleaning equipment performs at least the following steps:

[0105] Control the main fan to operate at the first power for a first duration;

[0106] After the main fan operates at the first power for a first duration, control the main fan to operate at the second power for a second duration;

[0107] After the main fan has been running at the second power for a second period of time, control the main fan to run at the third power.

[0108] Among them, the third power is greater than the second power, the second power is greater than the first power, and the second duration does not exceed one-fifth of the first duration.

[0109] In this embodiment, the first power can refer to a relatively low power level, which can be used in the initial stage of self-cleaning to perform cleaning tasks on components such as the throat in the suction pipe. For example, the first power can be 20W.

[0110] The first duration can refer to the duration during which the main fan operates at its first power level, serving as the time reference required to complete the initial cleaning phase. For example, the first duration could be 10 seconds.

[0111] The second power level can refer to an intermediate power level between the first and third power levels, used as a buffer or transition during the power increase process to smooth out the power change curve. For example, the second power level could be 35W.

[0112] The second duration can refer to the duration during which the main fan operates at its second power level. Since the second duration does not exceed one-fifth of the first duration, it ensures the transition phase is sufficiently short, serving as a buffer without affecting overall cleaning efficiency. For example, the second duration could be 0.5 seconds.

[0113] The third power level can refer to a relatively high power rating, mainly used in the later stages of self-cleaning processes to generate sufficient suction to efficiently draw the wastewater generated during cleaning into the wastewater tank. For example, the third power level could be 40W.

[0114] It should be noted that the specific values ​​of the third power, second power, first power, second duration, and first duration are not limited in the embodiments of this application, and can be set based on product performance parameters.

[0115] For example, Figure 4 A timing diagram of a floor scrubber performing self-cleaning, as provided in an embodiment of this application, is shown below. Figure 4 As shown by the black line, in the first cleaning mode, self-cleaning is performed by gradually increasing the power of the main fan in stages. The minimum steps performed by the floor scrubber include: first running at a lower first power P1 for a first duration of 10 seconds, then briefly transitioning at a second power P2, and further switching to a higher third power P3 for continuous operation.

[0116] It should be noted that the timing diagram corresponding to the dotted line in the figure, that is, the power rises from 0 to P4 and runs stably for a period of time, then the power drops sharply to 0, and then quickly rises to a higher power P5 and is maintained for a period of time, corresponds to the timing control diagram of the existing floor scrubber for self-cleaning. Since the power required for the existing technology is greater than the maximum power required for this application, it can be characterized that this application, by setting a stepped power control strategy that includes a transition power stage, not only effectively reduces the mechanical vibration and aerodynamic noise of the main fan caused by power changes during the self-cleaning process, making the noise change more gradual, but also significantly reduces the interference of noise fluctuations on the user's hearing, thereby significantly improving the user experience.

[0117] Compared to existing main fans that often start directly to high power or experience frequent start-stop cycles and abrupt power changes, leading to severe airflow impacts and mechanical vibrations and fluctuating noise, this application addresses the problem by setting a progressively increasing power sequence of first (low power), second (medium power), and third (high power), with each power level operating for a specific duration. This makes the main fan speed and airflow establishment process smooth and continuous, avoiding the impact noise caused by abrupt power changes. Furthermore, by establishing a clear duration relationship—the second power duration not exceeding 1 / 5 of the first power duration—the transition phase to the second power is very short. Thus, a smooth start and initial airflow guidance are achieved by operating at the first power for a longer duration, followed by a rapid transition to the third power with a short second power stage. This ensures a smooth transition and avoids prolonged lingering in the second power segment, preventing the generation of new, continuous noise sources. The overall noise curve is characterized by a "rapid and smooth ascent to high power," rather than fluctuating back and forth between multiple power levels. Furthermore, this application clarifies that the first cleaning mode is a step-by-step power increase process, rather than the repeated start-stop or high-low power cyclic switching process that may exist in the prior art, thereby reducing frequent high-low power switching and effectively avoiding the intermittent and repetitive noise interference generated in the prior art.

[0118] Therefore, this application effectively suppresses the mechanical vibration and aerodynamic noise caused by sudden changes in the main fan during the power increase process by using refined power timing control with low power start-up, short transition, and step-by-step ramp-up to high power. This greatly reduces interference to users and significantly improves the user experience of the cleaning equipment during the self-cleaning process.

[0119] Optionally, when the main fan is running at the first power for the first duration, some of the liquid in the cleaning tank is drawn to the inner wall of the suction pipe and remains in the suction pipe, so that some of the liquid cleans the suction pipe.

[0120] For example, the first power is configured such that the negative pressure suction generated inside the suction pipe is equal in magnitude and opposite in direction to the gravitational component of the liquid flowing on the inner wall of the suction pipe.

[0121] It should be noted that during the self-cleaning process, by precisely controlling the main fan to operate at its lowest power, the negative pressure suction generated inside the suction pipe is precisely balanced with the gravitational component of the liquid flowing along the inner wall of the pipe. This balance allows some of the liquid drawn from the cleaning tank to flow along and temporarily remain on the inner wall of the suction pipe, thereby achieving wetting and cleaning of the inner wall of the suction pipe.

[0122] In this way, by utilizing the principle of fluid dynamics balance, a small amount of liquid drawn during the first power operation phase is used to wet and preliminarily rinse the inner wall of the suction pipe without the need for additional cleaning equipment or complex control. This helps to soften or remove dried stains, hair, or particles adhering to the inner wall of the suction pipe, preventing dirt from accumulating inside the pipe and reducing the risk of blockages, odors, or bacterial growth caused by long-term dirt residue in the pipe, thus improving the overall cleanliness and ease of maintenance of the cleaning system.

[0123] Optionally, the method also includes:

[0124] After the main fan operates at the third power for a third duration, control the main fan to operate at the second power for a second duration;

[0125] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the first power for a fourth duration.

[0126] In this embodiment, the third duration may refer to the duration during which the main blower operates at the third power, which is the main stage required to complete the efficient sewage suction task. For example, the third duration is 15 seconds.

[0127] The fourth duration can refer to the time during which the main fan operates at its initial power after a step-down reduction in power, used for supplementary cleaning of the inner wall of the suction pipe after the main suction is completed. For example, the fourth duration is 5 seconds.

[0128] For example, such as Figure 4 As shown, in the first cleaning mode, after switching to the higher third power P3 and running for a third duration of 15 seconds, it briefly transitions to the intermediate second power P2, and then switches to the lower first power P2 and runs for a fourth duration of 5 seconds.

[0129] It should be noted that the specific numerical values ​​corresponding to the third and fourth durations are not limited in the embodiments of this application, and they can be set based on product performance parameters.

[0130] In this way, this application achieves a smooth shutdown of the main fan by setting a stepped power reduction process of "high power - medium power - low power". Furthermore, by incorporating a buffer phase during power reduction, it avoids the vibration and noise impact that might occur when shutting down abruptly from the third power level or dropping abruptly to the first power level, thus making the self-cleaning process more stable and quiet. Simultaneously, during the first power operation phase, a secondary cleaning of the inner wall of the suction pipe is performed, further optimizing the cleaning effect and contributing to a more thorough self-cleaning process.

[0131] Optionally, the cleaning device may perform the first cleaning mode multiple times, and this application embodiment does not specifically limit this.

[0132] Optionally, the method also includes:

[0133] During the operation of the main fan, the water pump assembly is kept in the on state.

[0134] "On" refers to the state in which the water pump assembly is started and in normal operation. In the on state, the water pump assembly can pump liquid from its water source (such as a clean water tank) to the cleaning tank.

[0135] In this way, during the self-cleaning process, while the main fan is operating in the first cleaning mode, the water pump assembly can be simultaneously kept on, working in tandem with the suction action of the main fan. This ensures a continuous supply of cleaning water or cleaning solution to the cleaning tank, maintaining an effective cleaning liquid level and flow within the tank. This helps the roller brush to be fully soaked and rinsed, improving the efficiency of dissolving and removing dirt from the roller brush surface. Simultaneously, in conjunction with the suction action of the main fan, a synergistic cleaning effect of rinsing and removing dirt is achieved, thereby enhancing the overall cleaning effect and efficiency of the self-cleaning process.

[0136] Optionally, the method also includes:

[0137] During the operation of the main fan at the first power, the water pump assembly is controlled to increase the liquid output to the first liquid output; the first liquid output is greater than the second liquid output; the second liquid output is the liquid output corresponding to the water pump assembly during the operation of the main fan at the second power and / or the third power.

[0138] In this embodiment, the first liquid output can refer to the liquid flow rate per unit time controlled and output by the water pump assembly during the operation of the main fan at the first power, which is a relatively high flow rate value.

[0139] The second output flow rate can refer to the liquid flow rate per unit time controlled by the pump assembly during the operation of the main fan at the second and / or third power, which is a flow rate value that is relatively lower than the first output flow rate.

[0140] It should be noted that the embodiments of this application do not limit the specific values ​​of the first and second liquid output volumes.

[0141] For example, the liquid output of the water pump assembly can be differentiated at different power stages of the self-cleaning process of the floor scrubber. For instance, during the period when the main fan operates at a lower first power, the water pump assembly can be controlled to supply water at a higher first liquid output; while during the period when the main fan operates at a higher second and / or third power, the water pump assembly can be controlled to supply water at a lower second liquid output. This provides more liquid during the low-power cleaning stage, helping to thoroughly wet and rinse the roller brush and the inner walls of the suction pipe, increasing the cleaning effect; reducing the liquid supply during the high-power suction stage avoids excessive liquid supply affecting suction efficiency or causing splashing, thereby improving the overall process energy efficiency and stability while ensuring cleaning effectiveness.

[0142] By increasing the water pump output during the initial power operation phase of the main blower, more liquid can be injected into the cleaning tank during periods of relatively weak suction. This ensures thorough soaking and wetting of the roller brush and effective rinsing of the inner walls of the suction pipe. This helps soften and remove stubborn stains, dilutes highly concentrated wastewater, thereby improving overall cleaning efficiency and preventing problems such as dry running of the pump or incomplete cleaning due to insufficient liquid.

[0143] Optionally, the cleaning equipment also has a second cleaning mode, and the method further includes:

[0144] After the first cleaning mode ends, control the cleaning equipment to enter the second cleaning mode;

[0145] In the second cleaning mode, the water pump assembly is switched from the on state to the off state.

[0146] In this embodiment, the second cleaning mode can refer to a preset self-cleaning operation mode, used to clean the roller brush and remove residual liquid by relying on mechanical scrubbing action combined with the suction force of the fan when the liquid supply stops. This second cleaning mode is a supplementary cleaning after the first cleaning mode has ended. Optionally, the second cleaning mode may include a scrubbing mode for the roller brush, a cleaning mode for the suction pipe, and a suction mode for the remaining wastewater in the cleaning tank.

[0147] The "off" state refers to the water pump assembly stopping operation and no longer pumping liquid. In the off state, no new liquid is injected into the cleaning tank.

[0148] In this way, after the cleaning equipment completes the first cleaning mode, it can be controlled to automatically enter a preset second cleaning mode. In this second cleaning mode, the water pump assembly is switched from the on state to the off state, and the cleaning equipment performs specific cleaning actions. For example, mechanical action (such as high-speed rotating scrubbing of the roller brush) and continuous suction from the fan are used to effectively remove residual moisture from the roller brush, improving the cleanliness of the roller brush.

[0149] It should be noted that after the cleaning equipment completes the first cleaning mode, it may not immediately enter the second cleaning mode. It may cycle through the first cleaning mode multiple times before entering the second cleaning mode, or it may perform other cleaning modes before entering the second cleaning mode. This application embodiment does not limit this. This step is only to limit the second cleaning mode to be executed after the first cleaning mode.

[0150] Therefore, by entering a second cleaning mode that stops supplying liquid after the first cleaning mode, the continuous supply of liquid can be cut off. This helps reduce unnecessary liquid residue and accumulation in the cleaning tank during subsequent spin-drying or pure suction stages, thereby more efficiently utilizing the suction power of the main fan to dehydrate or remove residual liquid from the roller brush and pipelines, improving self-cleaning efficiency. Furthermore, the water pump assembly is an energy-consuming component. Turning it off promptly in the second cleaning mode, when no cleaning liquid supply is needed, eliminates unnecessary energy consumption and avoids excessive consumption of cleaning liquid.

[0151] Optionally, the method also includes:

[0152] In the second cleaning mode, the cleaning equipment performs at least the following steps:

[0153] The main fan was controlled to operate at its first power for a fifth period of time.

[0154] After the main fan operates at the first power for a fifth duration, the main fan is controlled to operate at the second power for a second duration; the fifth duration shall not exceed one-tenth of the second duration.

[0155] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the third power for a sixth duration.

[0156] In this embodiment, the fifth duration may refer to the duration during which the main fan operates at the first power in the second cleaning mode. This fifth duration is set to be extremely short (not exceeding one-tenth of the second duration) to accommodate the need for low water volume and rapid rinsing of the suction pipe during this stage. For example, the fifth duration is 20 seconds.

[0157] The sixth duration can refer to the duration during which the main fan operates at third power in the second cleaning mode. Since the amount of liquid to be pumped has decreased in the second cleaning mode, this sixth duration is typically shorter than the third duration in the first cleaning mode, in order to achieve efficient pumping while saving energy and time. For example, the sixth duration is 7 seconds.

[0158] It should be noted that the specific numerical values ​​corresponding to the sixth and fifth durations are not limited in this application embodiment, and can be set based on product performance parameters.

[0159] For example, such as Figure 4As shown, in the second cleaning mode, a stepped power control strategy is also adopted, but the running time of each stage is adaptively adjusted according to the task characteristics of the second cleaning mode (water pump shut-off, water volume reduction). For example, it first runs at a lower first power P1 for a fifth duration of 20 seconds, then briefly transitions to a middle second power P2, and further switches to a higher third power P3 to run continuously for a sixth duration of 7 seconds.

[0160] Thus, in the second cleaning mode, the stepped power control method for noise reduction is continued. A brief initial power operation helps to gently guide the initial airflow to clean the suction pipe and roller brush area when no new liquid is supplied. Then, based on the second power, the operation gradually increases to the third power and continues, avoiding violent splashing or impact noise caused by a sudden power increase. Simultaneously, considering the characteristics of the second cleaning mode—low water content and a focus on removing residual moisture—the duration of each power stage is optimized. While ensuring necessary cleaning and efficient suction of the suction pipe, the overall energy efficiency and time efficiency of the second cleaning mode are improved, and noise performance is optimized.

[0161] Optionally, the method also includes:

[0162] After the main fan operates at the third power for a sixth time, the main fan is controlled to operate at the second power for a second time.

[0163] After the main fan operates at the second power for a second duration, the main fan is controlled to operate at the first power for a seventh duration.

[0164] The seventh duration can refer to the duration of operation at the first power after the power of the second cleaning mode decreases in a stepwise manner. This is used to perform airflow cleaning of the suction pipe after the main suction is completed, so as to remove residual moisture.

[0165] It should be noted that the specific value of the seventh duration is not limited in the embodiments of this application, and it can be set based on product performance parameters.

[0166] For example, such as Figure 4 As shown, in the second cleaning mode, after switching to the higher third power P3 and running continuously for a sixth time for 7 seconds, the main fan is controlled to briefly transition to the intermediate second power P2, and then further switches to the lower first power P2 and runs continuously for a seventh time for 0.5 seconds.

[0167] Thus, in the second cleaning mode, this application can also achieve a smooth shutdown of the main fan by setting a stepped power reduction process of "high power - medium power - low power". This avoids the sudden stop of airflow, vibration, and noise impact that may occur when shutting down directly from high power, improving the stability and quietness of the cleaning equipment during the shutdown phase. At the same time, during the first power operation phase, residual moisture in the suction pipe and roller brush area can be cleaned, further optimizing the self-cleaning effect and helping the cleaning equipment enter a more stable state after the second cleaning mode ends.

[0168] Optionally, the method also includes:

[0169] During the operation of the main fan, the control roller rotates based on the first direction.

[0170] In this embodiment, the first direction may refer to a preset direction in which the roller brush is controlled to rotate during the self-cleaning process. This first direction is usually configured to be the same rotation direction as the cleaning device when performing normal cleaning work on the surface to be cleaned (e.g., forward or clockwise rotation direction). This embodiment does not limit the specific rotation direction corresponding to the first direction.

[0171] For example, at each stage of the self-cleaning process, regardless of the power at which the main fan is operating, the roller brush can be controlled to continuously rotate in a preset first direction.

[0172] In this way, during the suction process of the main fan, by controlling the continuous rotation of the roller brush in the first direction, the brush bristles and the cleaning tank structure can generate relative movement and friction, thereby more effectively removing stains and hair attached to the surface of the roller brush. The centrifugal force generated by the rotation also helps to throw the sewage and impurities inside the roller brush outward. Combined with the suction force of the main fan, a synergistic cleaning effect of mechanical peeling and fluid suction is formed, significantly improving the cleaning efficiency and effect of the roller brush.

[0173] Optionally, the cleaning equipment also has a second cleaning mode and a third cleaning mode, and the method further includes:

[0174] After the first or second cleaning mode ends, control the cleaning equipment to enter the third cleaning mode;

[0175] In the third cleaning mode, the cleaning equipment performs at least the following steps:

[0176] The control roller is kept in a stopped state, and the main fan is controlled to run at the fourth power for the eighth time.

[0177] After the main fan operates at the fourth power for eight hours, the control brush rotates in the second direction, and the main fan operates at the fifth power for nine hours.

[0178] Among them, the second direction is opposite to the first direction, and the fifth power is greater than the fourth power.

[0179] In this embodiment of the application, the third cleaning mode may refer to a preset self-cleaning operation mode. This third cleaning mode cleans the roller brush and other components such as the suction pipe by controlling the roller brush in two states: stationary and reverse rotation, combined with the suction of the main fan with different power.

[0180] The stopped operation state can refer to the brush drive motor being de-energized, and the brush being stationary and not rotating.

[0181] The fourth power level can refer to the power value at which the main fan is controlled to operate in the third cleaning mode, which is a relatively low power. For example, the fourth power level could be 30W.

[0182] The eighth duration can refer to the duration during which the main fan operates at the fourth power and the roller brush stops running in the third cleaning mode. For example, the eighth duration could be 1 second.

[0183] The second direction can refer to the direction in which the roller brush is controlled to rotate in the third cleaning mode, which is opposite to the first direction. This second direction is usually configured to be the opposite direction of rotation of the cleaning device when performing normal cleaning work on the surface to be cleaned (e.g., reverse or counterclockwise rotation direction). The embodiments of this application do not limit the specific rotation direction corresponding to the second direction.

[0184] The fifth power level can refer to the power value at which the main fan is controlled to operate in the third cleaning mode, which is a higher power value than the fourth power level. For example, the fifth power level could be 40W.

[0185] The ninth duration can refer to the duration during which the main fan operates at the fifth power level in the third cleaning mode. For example, the ninth duration could be 5 seconds.

[0186] It should be noted that the specific values ​​of the fourth power, the eighth duration, the second direction, the fifth power, and the ninth duration are not limited in the embodiments of this application, and can be set based on product performance parameters.

[0187] Optionally, the fourth power is equal to the first power.

[0188] For example, after completing the first or second cleaning mode, the cleaning equipment can be controlled to enter a third cleaning mode. This third cleaning mode can be divided into two stages: in the first stage, the roller brush is controlled to stop running, and the main fan is controlled to run at a lower fourth power; in the second stage, the roller brush is controlled to rotate in the opposite direction, while the main fan is controlled to run at a higher fifth power.

[0189] It should be noted that after the cleaning equipment completes the first or second cleaning mode, it may not immediately enter the third cleaning mode. It may cycle through the first or second cleaning mode multiple times before performing the second cleaning mode, or it may perform the third cleaning mode after performing other cleaning modes. This application embodiment does not limit this. This step is only to limit the third cleaning mode to be performed after the first or second cleaning mode.

[0190] Thus, by introducing a third cleaning mode, a deep cleaning and dehydration process is specifically performed on the roller brush after completing the first or second cleaning mode. By setting the roller brush to operate at a lower fourth power when it is not running, a preliminary, gentle airflow is used to loosen residual fine dirt on the surface and crevices of the roller brush, facilitating direction switching and preventing damage to the motor. Subsequently, the roller brush is controlled to rotate in the opposite second direction, while the main fan is increased to a fifth power. This reverse rotation changes the direction of force on the bristles, more effectively dislodging any dirt or wastewater that may have remained or become embedded during forward rotation, and then promptly removing it with enhanced suction. This combination of reverse rotation and powerful suction significantly improves the thoroughness and reliability of the self-cleaning process.

[0191] Optionally, the fourth power is greater than the first power.

[0192] In one possible implementation, the motor controller driving the main fan can output corresponding drive current or voltage at appropriate stages to achieve power control where the fourth power is greater than the first power. It should be noted that other power controls in the above embodiments can also be controlled using similar methods, and this application does not specifically limit them.

[0193] In this application, the fourth power of the main fan is set to be higher than the first power used for cleaning the suction pipe in the first cleaning mode.

[0194] By introducing an intermediate fourth power level into the main fan's power ramp-up path, a smoother and more controllable two-stage transition from the first to the fifth power level is achieved. The jump from the first to the fifth power level is a large-scale power change; this is broken down into two smaller power ramp-up steps: from the first to the fourth power level, and then from the fourth to the fifth power level. This reduces the power increment at each step, resulting in more gradual changes in the main fan speed and airflow intensity. This effectively reduces torque shocks, mechanical vibrations, and airflow turbulence caused by sudden power changes, leading to smoother operation. Furthermore, the design of the fourth power level being greater than the first power level provides the control algorithm with more precise adjustment tools. This allows the cleaning system to manage the power ramp-up rate more accurately, ensuring that the main fan and drive circuitry operate within safe electrical and thermal load ranges, improving the cleaning system's control robustness under complex conditions and long-term operational reliability. Moreover, the smoother power ramp-up process means that the intensity and frequency changes of the main fan noise are also more gradual. This helps avoid large transient noises or unpleasant pitch fluctuations, making the overall noise sound more continuous and stable, improving the user's auditory experience.

[0195] Optionally, the cleaning equipment also has a fourth cleaning mode, which includes the following methods:

[0196] After the third cleaning mode ends, control the cleaning equipment to enter the fourth cleaning mode;

[0197] In the fourth cleaning mode, the cleaning equipment performs at least the following steps:

[0198] Control the roller brush to be in a stopped state, and control the main fan to run at the sixth power for the eighth time;

[0199] After the main fan operates at the sixth power for eight hours, the control brush rotates based on the first direction, and the main fan operates at the fifth power for nine hours.

[0200] The sixth power is less than the fourth power.

[0201] In this embodiment, the fourth cleaning mode can refer to a preset self-cleaning operation mode, which is used to clean the roller brush and suction pipe by performing suction with lower power and combining it with the roller brush to resume rotation in the first direction. For example, the sixth power can be 20W.

[0202] The sixth power can refer to the power value at which the main fan is controlled to operate in the fourth cleaning mode, which is a power value lower than the fourth power value in the third cleaning mode.

[0203] It should be noted that the specific value of the sixth power is not limited in the embodiments of this application, and it can be set based on the product performance parameters.

[0204] Optionally, in the fourth cleaning mode, the cleaning device may also perform at least the following steps:

[0205] Control the roller brush to be in a stopped state, and control the main fan to run at the sixth power for ten hours;

[0206] After the main fan operates at the sixth power for ten hours, the control brush rotates in the first direction, and the main fan is controlled to operate at the fifth power for eleven hours. The tenth hour is not equal to the eighth hour, and the eleventh hour is not equal to the ninth hour.

[0207] For example, after completing the third cleaning mode, the cleaning equipment can be controlled to enter the fourth cleaning mode. This fourth cleaning mode can also be divided into two stages: in the first stage, the roller brush is controlled to stop rotating, and the main fan operates at a lower sixth power; in the second stage, the roller brush is controlled to resume forward rotation, while the main fan operates at a higher fifth power.

[0208] Thus, this application introduces a fourth cleaning mode. After the third cleaning mode, the rotation direction of the roller brush is switched again and the power of the main fan is adjusted to form a "reset cleaning" stage. This stage involves operating the main fan at a lower sixth power while the roller brush is stopped, allowing for a gentle initial blowing and tidying of the roller brush after the reverse strong cleaning. Subsequently, the roller brush is controlled to rotate in the initial first direction, and with the help of a stronger fifth power suction, the bristles are restored to their normal working direction. At the same time, any loosened residue or wastewater during the reset process is removed, and the airflow is combed through the roller brush to ensure that it is clean, fluffy, and correctly oriented in a standby state, ready for the next cleaning operation.

[0209] Optionally, the sixth power is equal to the first power.

[0210] Optionally, after the main fan has been running at the sixth power for eight hours, the main fan can be gradually increased to the fifth power.

[0211] In this way, after the main fan has operated at the fourth power for eight hours, the power can be reduced to a verified and stable first power. This step acts as a "reset," establishing a lower starting point for the main fan's subsequent power ramp-up. Further, starting from the lower first power, the power can be gradually increased to the fifth power. This process can reuse or draw upon the verified, gradual power ramp-up strategy (e.g., step-by-step increase) from the first cleaning mode. This ensures that even when switching between different cleaning modes, the main fan's transition to high-power operation is smooth, controlled, and low-noise. Furthermore, this method of first reducing to the first power and then increasing to the fifth power significantly reduces the amplitude and rate of power change near the mode switching point compared to directly switching or jumping from the fourth power to the fifth power. This effectively suppresses potential electrical stress, mechanical vibration, and sudden changes in airflow noise that may occur during mode switching, resulting in smoother transitions between different modes in the self-cleaning process and more stable overall operation.

[0212] In the foregoing embodiments, the self-cleaning method of the cleaning equipment provided in this application has been described. To achieve the functions of the methods provided in the embodiments of this application, the electronic device serving as the execution subject may include hardware structures and / or software modules, implementing the above functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. Whether a particular function is executed in the form of hardware structures, software modules, or a combination of hardware structures and software modules depends on the specific application and design constraints of the technical solution.

[0213] For example, Figure 5 This application provides a schematic diagram of the structure of a self-cleaning device for a cleaning equipment, applied to a cleaning system. The cleaning system includes a cleaning device and a cleaning base station. The cleaning device includes a roller brush and a main fan for generating suction. When the roller brush is located in the cleaning tank of the cleaning base station, the cleaning device performs a self-cleaning action. The cleaning device has a first cleaning mode, such as... Figure 5 As shown, the self-cleaning device 500 of the cleaning equipment includes:

[0214] The first control module 501 is used to control the cleaning equipment to enter the first cleaning mode in response to the self-cleaning command;

[0215] The second control module 502 is used to control the cleaning equipment to perform at least the following steps in the first cleaning mode:

[0216] Control the main fan to operate at the first power for a first duration;

[0217] After the main fan operates at the first power for a first duration, control the main fan to operate at the second power for a second duration;

[0218] After the main fan has been running at the second power for a second period of time, control the main fan to run at the third power.

[0219] Among them, the third power is greater than the second power, the second power is greater than the first power, and the second duration does not exceed one-fifth of the first duration.

[0220] Optionally, the cleaning equipment also includes a suction pipe.
