Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, and in particular to a cleaning disc, a cleaning base station, and a cleaning control method. Background Technology
[0002] In existing technologies, cleaning equipment such as cleaning robots and mops often have cleaning components (such as roller brushes, rubber brushes, or mops) that easily accumulate large amounts of dust, hair, and wet dirt during operation. To ensure cleaning performance and reduce user maintenance workload, a self-cleaning structure for the cleaning components is usually installed in the base station or cleaning tray. For example, scrapers, bristles, and water flow structures are installed in the receiving cavity or washing tank to scrape and rinse the surface of the cleaning components.
[0003] For example, Chinese patent CN223392409U discloses a cleaning base station solution for cleaning equipment, which removes attached dirt by arranging a scraping structure in the cleaning tank in conjunction with water flow to scrape and rinse cleaning components such as roller brushes.
[0004] However, in the aforementioned existing technologies, the scraping structure is mostly fixed, and its contact state with the cleaning component often depends on the component's posture, deformation, and the user's placement method. This makes it difficult to maintain a stable and reproducible scraping contact relationship under different working conditions, resulting in fluctuations in the removal of dirt from the cleaning component's surface and unstable cleaning performance. Furthermore, existing solutions have relatively crude organization and management of the water channels within the cavity. Hair and fibrous dirt generated during the cleaning process easily accumulate and entangle near the scraper and blades, affecting the normal operation of the scraping structure. Simultaneously, wastewater and residual liquid can stagnate or backflow in localized areas, easily causing secondary contamination of the cleaning component and the inner wall of the cavity. Summary of the Invention
[0005] The purpose of this invention is to overcome the problem that the prior art can easily cause secondary pollution to the cleaning components and the inner wall of the cavity, and to provide a cleaning disc, a cleaning base station and a cleaning control method to reduce the risk of entanglement and suppress secondary pollution caused by sewage backflow and residual liquid retention, thereby improving the reliability of the overall cleaning process.
[0006] According to one aspect of the present invention, a cleaning tray is provided for cleaning cleaning components in a cleaning device, the cleaning tray comprising:
[0007] Receptacle,
[0008] A scraping assembly is disposed within the receiving cavity. The scraping assembly includes a scraping element rotatable about a first axis and a drive conversion assembly pulsatingly connected to the scraping element. The drive conversion assembly is used to convert driving force into rotation of the scraping element about the first axis.
[0009] The scraping member switches between a scraping position and a retraction position under the drive of the drive conversion assembly: in the scraping position, at least a portion of the scraping member contacts the cleaning member to scrape off the adhering dirt on the cleaning member; in the retraction position, the scraping member moves away from the receiving cavity.
[0010] By arranging a scraper that can rotate around a first axis and a drive conversion assembly that is connected to the scraper within the receiving cavity, the driving force can be stably converted into the rotation of the scraper around the first axis. This allows for continuous or reciprocating scraping of the surface of the cleaning component as it passes through the receiving cavity, thus more thoroughly removing dirt adhering to the cleaning component. Compared to a fixed scraper structure, this ensures that the scraping force and rotation speed remain within a stable range, preventing dirt residue due to insufficient power or damage to the cleaning component due to sudden changes in power. This significantly improves the cleanliness of the cleaning component, thereby ensuring the cleaning effect of the cleaning equipment on the target area (floor, countertop, etc.) in the future.
[0011] By limiting the scraping component to switch between a scraping position and an avoidance position under the drive of the drive conversion component, the scraping component is positioned in the scraping position and in contact with the cleaning component when cleaning is required. This reduces additional mechanical interference and wear between the cleaning component and the scraping component. Furthermore, combined with the flow path of the cleaning fluid in the receiving cavity, it facilitates orderly management of the water path, reduces the accumulation of hair and fibrous dirt in local areas, reduces the risk of entanglement, and inhibits secondary pollution caused by sewage backflow and residual liquid retention, thereby improving the reliability of the overall cleaning process.
[0012] In some exemplary embodiments of the present invention, based on the foregoing solution, the cleaning tray is provided with a water inlet channel;
[0013] At the scraping position, the scraper and at least a portion of the receiving cavity together define a water storage section for storing water; the water inlet channel connects an external water supply port and the water storage section; at least a portion of the cleaning member is located in the water storage section to contact the water in the water storage section during rolling and to be scraped away by the scraper.
[0014] At the scraping position, the scraping component and the receiving cavity structure together define the water storage section. On the one hand, the water in the water storage section can initially moisten and clean the surface of the cleaning component, reducing the amount of dry and hardened stains carried by the cleaning component. On the other hand, when the cleaning component rolls to the scraping position, the wet stains are more easily peeled off by the scraping component, reducing scraping resistance and more thoroughly removing stains and impurities attached to the surface of the cleaning component. This prevents stains from remaining on the surface of the cleaning component and re-contaminating the cleaned area as it rolls, significantly reducing cleaning residue and improving the overall cleaning quality.
[0015] Secondly, the structural design of the water inlet channel, water storage section, and scraping component forms an integrated functional link for water supply, water storage, wetting of the cleaning component, and scraping of stains. There is no need to set up separate wetting and scraping mechanisms for the cleaning component, which effectively simplifies the overall structure of the cleaning disc, reduces the number of parts, and lowers the size and manufacturing cost of the device. At the same time, this design does not require frequent manual intervention, such as manually adding water to the cleaning component or cleaning the scraping component, which improves the degree of automation and ease of use, and is more compatible with various automated cleaning equipment, such as automatic sweeping machines and cleaning robots.
[0016] In addition, the cleaning component comes into contact with water in the water reservoir during rolling. This wet state reduces the coefficient of friction between the cleaning component and the target surface, as well as between the cleaning component and the scraping component. This prevents the surface of the cleaning component from wearing out too quickly due to dry friction, such as bristles collapsing or cleaning cloth fibers breaking. At the same time, the scraping component removes soft, wet stains rather than hard, dry stains, reducing scratch damage to the surface of the cleaning component during the scraping process. This significantly reduces the wear rate of the cleaning component, extends its replacement cycle and overall service life, and lowers user operating costs.
[0017] In some exemplary embodiments of the present invention, based on the foregoing scheme, the cleaning tray is provided with a water outlet channel and a drain outlet;
[0018] At the scraping position, the scraping member divides the receiving cavity into a water storage section and a drainage section;
[0019] At the avoidance position, the water storage section, the drainage section, the water outlet channel, and the drain outlet are connected in sequence. The sewage in the water storage section flows along the scraper to the drainage section and is guided through the water outlet channel to the drain outlet to be discharged from the cleaning tray.
[0020] By switching between the scraping and avoidance positions, the cleaning tray can seamlessly integrate cleaning operations and wastewater discharge according to actual needs. During cleaning, the water level in the reservoir remains sufficient to keep the cleaning components moist, eliminating concerns about wastewater interference. Once cleaning is complete or wastewater accumulates to a certain level in the reservoir, switching to the avoidance position allows for rapid wastewater discharge without disassembling the cleaning tray or requiring additional cleaning. This significantly simplifies the operation process and is particularly suitable for the continuous operation requirements of automated cleaning equipment, preventing frequent shutdowns for wastewater discharge from impacting cleaning efficiency.
[0021] Secondly, the design of the wastewater flowing along the scraper to the drain section utilizes the structural form of the scraper to provide directional guidance for the wastewater, avoiding local stagnation caused by disordered flow of wastewater within the receiving cavity. At the same time, the sequential connection design of the water storage section, drain section, water outlet channel and drain outlet forms a directional drainage gradient, which can reduce drainage dead corners inside the cleaning tray, prevent wastewater from remaining in the cavity for a long time, thus avoiding the growth of bacteria and the generation of odors, balancing cleaning function and hygiene, and extending the service life of the cleaning tray.
[0022] Furthermore, there is no need to set up separate drainage valves or partition components. The function of separation and connection can be directly achieved by switching the position of the scraper. The scraping, water storage and drainage functions are deeply integrated with the same structure (scraper), reducing the number of internal parts of the cleaning disc, simplifying the overall structural design and assembly process, and reducing production and manufacturing costs. At the same time, the integrated structure reduces the connection gaps between parts, reduces the risk of sewage leakage from the gaps, and improves the overall sealing and reliability of the device.
[0023] In some exemplary embodiments of the present invention, based on the foregoing scheme, along the height direction of the cleaning tray, the bottom surface of the drainage section is higher than the bottom surface of the water outlet channel; the bottom surface of the water outlet channel is higher than the opening of the drain outlet, so that the sewage located in the drainage section flows sequentially to the water outlet channel and the drain outlet under the action of gravity.
[0024] A stepped height difference is created along the height of the cleaning tray, with the bottom of the drainage section > the bottom of the outlet channel > the opening of the drain outlet, providing a natural gravitational potential energy difference for sewage flow. Sewage in the drainage section can automatically flow to the lower outlet channel under gravity, without relying on additional power units. Efficient drainage is achieved simply by optimizing the height of each drainage component, significantly simplifying the internal structure of the cleaning tray, reducing the number of parts and assembly processes, and lowering manufacturing costs. Furthermore, the non-powered design reduces the use of moving parts and electrical components, avoiding risks such as power unit failure and control component malfunction, improving the stability and reliability of the drainage system, and reducing later maintenance costs. After entering the outlet channel, the sewage flows along the height advantage of the channel bottom to the lowest drain outlet. The entire process requires no manual intervention or mechanical drive, greatly improving drainage efficiency and avoiding sewage accumulation problems caused by power failure.
[0025] Secondly, the drainage section needs to receive the wastewater guided by the scraper, with its bottom surface set at a relatively high position. This prevents wastewater from flowing back into the storage section and matches the tilt angle of the scraper. The water outlet channel, as an intermediate guide structure, can be flexibly planned according to the height difference of its bottom surface without occupying the core cleaning area. The drain outlet is set at the lowest point for easy connection to external sewage pipes (such as the wastewater tank of the cleaning equipment). This layout not only improves the utilization rate of the internal space of the cleaning tray but also reduces connection gaps through the height connection of various components, improving overall sealing and preventing wastewater leakage.
[0026] In some exemplary embodiments of the present invention, based on the foregoing scheme, the water inlet channel is located above the water outlet channel along the height direction of the cleaning tray.
[0027] The water inlet channel is positioned above the water outlet channel along the height of the cleaning tray, creating a layered structure with clean water above and wastewater below. Clean water delivered through the inlet channel flows directly to the water storage section in the upper area to wet the cleaning components; while wastewater collected and discharged through the outlet channel comes from the drainage section below. There is no overlap in their flow paths, and a clear height difference exists between them. This prevents wastewater from entering the inlet channel or contaminating the cleaning water supply due to backflow or leakage, thus avoiding the risk of cross-contamination between clean water and wastewater. This ensures that each cleaning of the cleaning components comes into contact with clean water, guaranteeing consistent cleaning results.
[0028] Secondly, the cleaning tray must simultaneously accommodate core components such as the water storage section, drainage section, and scraper. The top-in, bottom-out vertical layout of the water inlet and outlet channels fully utilizes the vertical space of the cleaning tray. The water inlet channel can be arranged along the upper area of the cleaning tray (such as the side wall near the top of the water storage section), without occupying the installation space of the drainage components below; the water outlet channel can extend along the lower area of the cleaning tray, naturally connecting with the low-position design of the drain outlet. This layered layout avoids spatial overlap and interference between channels, eliminating the need to increase the volume of the cleaning tray to accommodate channels. It achieves efficient integration of water supply and drainage functions within a limited space, improving the overall structural compactness.
[0029] Furthermore, the inlet channel delivers clean water, and its core requirement for sealing is to prevent leakage. The outlet channel, on the other hand, discharges wastewater, and the primary concern is preventing wastewater leakage and contamination of the equipment's interior. Placing the inlet channel at the top ensures that its connection points, such as those to external water supply inlets, are located away from areas where wastewater tends to accumulate, reducing the likelihood of wastewater corroding the interface seals. The outlet channel, located at the bottom, allows even minor leaks to be guided to the drain outlet via the drainage structure at the bottom of the cleaning tray (such as a pre-designed collection trough), preventing wastewater from spreading upwards to the inlet channel or other core components of the cleaning tray. Additionally, the height difference between the two channels reduces the need for cross-connections, mitigating sealing difficulties caused by multiple channel intersections and improving the overall leak-proof reliability of the cleaning tray.
[0030] In some exemplary embodiments of the present invention, based on the foregoing solution, an isolation element is provided on the water outlet channel, the isolation element being used to isolate some impurities in the wastewater.
[0031] The isolation component provides preliminary filtration of wastewater flowing into the drain outlet, intercepting solid impurities such as dust particles, hair, and fiber debris. This prevents these impurities from entering downstream pipes, such as the sewage pipe connected to the drain outlet or the wastewater tank interface of cleaning equipment. On one hand, it prevents impurities from depositing and caking on the inner wall of the outlet channel, avoiding a decrease in drainage flow rate due to a reduction in the channel cross-sectional area. On the other hand, it eliminates blockages caused by impurities getting stuck in the drain outlet or downstream pipe connections, ensuring the long-term unobstructed drainage path of the drain section, outlet channel, and drain outlet, guaranteeing the stability of wastewater discharge, and avoiding the risk of wastewater backflow and siltation due to blockages.
[0032] Without a barrier, hard impurities in the wastewater will impact downstream components (such as seals in the wastewater tank and valves in the drain pipe) with the water flow. Over time, this can cause wear and tear, reduce sealing performance, or even lead to valve malfunction. Furthermore, impurities mixed with wastewater and deposited within downstream components increase cleaning difficulty and may even promote bacterial growth. A barrier, by intercepting impurities in advance, significantly reduces contact between downstream components and these impurities, lowers the risk of wear, maintains the cleanliness of downstream components, and thus extends the lifespan of the cleaning tray and the entire cleaning equipment (such as a cleaning robot), reducing maintenance frequency and costs.
[0033] For cleaning equipment equipped with a detachable wastewater tank, impurities trapped by the separator remain in the outlet channel (or the separator itself is washable). During subsequent cleaning, users only need to clean the separator or the impurities in the outlet channel, eliminating the need for additional filtration of the wastewater in the tank. Furthermore, if wastewater needs to be directly discharged into an external drainage system (such as a household sewer), the separator prevents impurities from entering the sewer and causing blockages in the public pipes, reducing the hassle of subsequent sewer blockage repairs and significantly improving the ease of use and reducing the user's operational burden.
[0034] In some exemplary embodiments of the present invention, based on the foregoing solution, the scraping element includes:
[0035] A rotating shaft, wherein the axis of the rotating shaft is the first axis;
[0036] The scraping section has a first end connected to the rotating shaft and a second end away from the first end;
[0037] In the scraping position, the second end contacts the cleaning component; in the avoidance position, the scraping part and the bottom surface of the water storage part form a drainage channel, and the drainage channel at least partially diverts the sewage in the water storage part to the drainage part.
[0038] The scraping component, through a combination of a rotating shaft and a scraping part, can switch between two core functions simply by rotating around a first axis. In the scraping position, the second end of the scraping part directly contacts the cleaning component, efficiently scraping away stains and impurities (such as dust, hair, and wet debris) adhering to the surface of the cleaning component, ensuring the continuous cleaning capability of the cleaning component. When switched to the avoidance position, the scraping part and the bottom surface of the water storage section form a drainage channel, eliminating the need for additional independent drainage components, and can guide the wastewater in the water storage section to the drainage section in a directional manner. This achieves integrated scraping and drainage functions, greatly simplifying the internal structure of the cleaning disc, reducing the number of parts, lowering the device size and manufacturing cost, and avoiding the risk of multi-component collaborative failures.
[0039] The dual-mode switching of the scraping component can be achieved solely through the unidirectional / bidirectional rotation of the rotating shaft, eliminating the need for complex multi-degree-of-freedom drive mechanisms (such as translation and lifting components). The drive conversion component only needs to rotate the rotating shaft around the first axis by a preset angle to complete the position adjustment of the scraping part, significantly simplifying the power transmission structure and reducing drive energy consumption. At the same time, the rotary structure has fewer moving parts and lower friction loss, which, compared to multi-component collaborative drive, reduces the risk of failures such as jamming and wear, improves the long-term operational stability of the scraping component, and reduces maintenance costs.
[0040] In some exemplary embodiments of the present invention, based on the foregoing scheme, the driving conversion component includes:
[0041] An actuator is disposed on the cleaning component;
[0042] The paddle is coaxially connected to the scraper.
[0043] One end of the transmission rod is connected to the output shaft of the actuator; the other end is in intermittent contact with the paddle.
[0044] The rotation of the actuator is converted into a reciprocating thrust on the paddle via the transmission rod. The paddle drives the scraper to reciprocate around the first axis, so that the scraper switches between the scraping position and the avoidance position.
[0045] The drive conversion assembly, through a transmission link of actuator, transmission rod, and paddle, stably converts the rotary motion of the actuator into the reciprocating thrust of the paddle. When the actuator output shaft rotates, it drives one end of the transmission rod to perform a circular motion, while the other end intermittently contacts the paddle, pushing the paddle to reciprocate around the first axis, thereby precisely switching the scraping component to the scraping position or the avoidance position. Compared to solutions that use multiple motors to drive the components separately or rely on complex gear sets, this assembly can complete the motion conversion of rotation, reciprocating thrust, and reciprocating rotation using only three core components: actuator, transmission rod, and paddle. It eliminates the need for additional reduction or reversing mechanisms, reducing the number of parts and assembly steps, lowering manufacturing costs, and also reducing frictional losses between moving parts, thus improving the long-term reliability of the assembly.
[0046] The actuator is directly mounted on the cleaning component, eliminating the need for additional external space on the cleaning tray. The paddle and scraper are coaxially connected, allowing for integrated assembly using the scraper's mounting axis and avoiding the need for additional installation space. The drive rod employs a rod-like structure, allowing for flexible design of its length and direction (e.g., extending along the edge of the cleaning component) based on the internal space of the cleaning tray, without interfering with core functional areas such as the water storage and drainage sections. This layout design achieves efficient integration of the drive function and core components within the limited space of the cleaning tray, avoiding an increase in the overall size of the cleaning tray due to excessively large drive components, and is suitable for the design requirements of miniaturized cleaning equipment (such as portable cleaners and small robotic vacuum cleaners).
[0047] In some exemplary embodiments of the present invention, based on the aforementioned scheme, a first gear is provided on the outer periphery of the output shaft of the actuator, the first gear is coaxial with the output shaft of the actuator, and its axis is parallel to the first axis; a second gear is provided on the transmission rod that meshes with the first gear, the second gear is integrally formed with the transmission rod, and the axis of the transmission rod is perpendicular to the first axis, so as to transmit the output torque of the actuator to the transmission rod.
[0048] The perpendicular meshing structure of the first and second gears precisely converts the rotational power of the actuator output shaft into the running power of the transmission rod. This power direction conversion design, on the one hand, eliminates the need for complex linkages or universal joints to achieve steering, significantly simplifying the spatial layout and avoiding structural redundancy caused by directional conflicts in the power transmission path; on the other hand, gear meshing is a rigid transmission, which, compared to friction transmission (such as belt transmission, friction wheel transmission) or flexible transmission (such as rope transmission), enables slip-free power transmission, efficiently transferring the actuator's output torque to the transmission rod and significantly reducing power loss. Simultaneously, the stable contact area and uniform force transmission of the meshing gears prevent power interruption or torque fluctuations caused by transmission slippage, ensuring the transmission rod receives continuous and stable torque. This, in turn, drives the paddle to smoothly switch the scraper's position, preventing the scraper from jamming or shifting due to unstable power.
[0049] Secondly, gear transmission has a defined transmission ratio (transmission ratio = number of teeth on the first gear / number of teeth on the second gear). By designing the first and second gears with a fixed tooth ratio, the rotation angle of the actuator output shaft and the rotation angle of the transmission rod can be precisely correlated to control the stroke of the transmission rod. Furthermore, through the cooperation of the transmission rod and the paddle, the rotation angle of the scraper around the first axis can be precisely controlled (e.g., ensuring that the contact pressure between the second end and the cleaning part is consistent when the scraper is switched to the scraping position; and that the gap size of the drainage channel is stable when switched to the avoidance position). This high transmission precision avoids the positional deviation of the scraper caused by transmission errors, ensuring the reliability of the cleaning and sewage discharge functions.
[0050] In some exemplary embodiments of the present invention, based on the foregoing scheme, the scraping member includes a scraping portion, and the included angle between the scraping portion and the paddle is 40 degrees to 50 degrees.
[0051] The 40°-50° angle between the scraping section and the lever falls within the efficient force transmission angle range. When the lever rotates around the first axis under the push of the transmission rod, this angle allows the driving force to be transmitted more smoothly along the structural axis of the scraping section, reducing force distribution losses. This avoids situations where the angle is too small, causing some of the driving force to be converted into compressive stress on the bottom surface of the water storage section, or where the angle is too large, causing the driving force to be dispersed and requiring more power to push the scraping section to switch positions. On the one hand, this reduces the energy consumption of the actuator's drive condition switching (no need to output additional power to compensate for force loss), and on the other hand, it reduces stress concentration at the connection between the lever and the scraping section caused by poor force transmission (avoiding long-term overload in this area leading to fracture and deformation), improving the overall durability and operational stability of the scraping component.
[0052] In some exemplary embodiments of the present invention, based on the foregoing scheme, the drive conversion component includes a stop portion, the stop portion being coaxially disposed with the scraper, and the stop portion and the paddle being respectively disposed at both ends of the scraper along the extension direction of the first axis.
[0053] When the scraper rotates around the first axis, if the driving force is transmitted solely by the paddle on one side, uneven axial force can easily cause the scraper to "eccentrically wobble" (such as one end of the scraping part tilting or uneven contact with the cleaning part). Long-term use will exacerbate the wear of the fit clearance between the scraper and the rotating shaft, and may even cause the rotating shaft to jam. The abutment and the paddle are located at opposite ends of the axial direction of the scraper. On the one hand, when the paddle transmits the driving force, the abutment can act as an axial support point to balance the force distribution of the scraper and avoid wobble caused by unilateral force. On the other hand, the coaxial arrangement of the two ensures that the rotation axis of the scraper always coincides with the first axis, reducing radial runout during rotation, reducing frictional wear between the scraper and surrounding components (such as the bottom surface of the water storage section and the inner wall of the receiving cavity), extending the service life of the scraper and the rotating shaft, and improving the overall structural stability.
[0054] During operation and stain removal, the scraping component must withstand multi-directional forces, including driving force, cleaning component reaction force, and sewage impact. Long-term use can lead to axial deformation due to insufficient structural strength (such as scraping component bending or loosening of the connection between the rotating shaft and the scraping part). The stop and the lever are located at opposite ends of the axial direction. Firstly, their coaxial connection forms a stable whole with the scraping component, dispersing the multi-directional forces on the scraping component and preventing stress concentration in the middle of the scraping component or at the rotating shaft connection. This effectively suppresses bending deformation under stress, ensuring the structural stability of the scraping part, significantly improving the long-term operational reliability of the scraping component, and reducing functional failures caused by structural deformation. Secondly, it allows for full utilization of the axial length of the scraping component to accommodate functional components, eliminating the need for additional space for the stop. It also avoids spatial redundancy or component interference at both ends of the scraping component's axial direction. Thus, while ensuring limiting and support functions, it minimizes the space occupied by the drive conversion assembly, improving the overall compactness of the cleaning disc structure.
[0055] In some exemplary embodiments of the present invention, based on the foregoing scheme, the scraping member includes a scraping portion, and the included angle between the scraping portion and the blocking portion is 3 to 7 degrees.
[0056] If the scraping section and the blocking section have no angle or the angle is too small, the scraping section is prone to being in a vertical state due to gravity or assembly errors. This results in the scraping section being tightly fitted to the bottom surface of the water outlet channel or having a very small gap, making it impossible for sewage to be discharged normally. However, a small angle of 3 to 7 degrees can provide stable tilting guidance for the scraping section, ensuring that it always maintains a slight tilted posture when in the avoidance position. It leaves a channel gap between the scraping section and the bottom surface of the water outlet channel to accommodate the flow of sewage. This gap is neither too narrow, which would cause blockage, nor too wide, which would lose its directional guiding function. This solves the problem of vertical downward flow causing the drainage function to fail, and ensures that sewage can flow smoothly to the drainage section along the tilted scraping section.
[0057] According to a second aspect of the present invention, a cleaning base station is provided, the cleaning base station being used at least for cleaning cleaning components in a cleaning device, the cleaning base station comprising a cleaning tray, the cleaning tray comprising:
[0058] Receptacle;
[0059] A scraping assembly is disposed within the receiving cavity. The scraping assembly includes a scraping element rotatable about a first axis and a drive conversion assembly pulsatingly connected to the scraping element. The drive conversion assembly is used to convert driving force into rotation of the scraping element about the first axis.
[0060] The cleaning base station has a clean state and a non-clean state. In the non-clean state, the scraper is located in a clearance position and is away from the receiving cavity. In the clean state, the cleaning component is located inside the receiving cavity. The scraper is switched from the clearance position to the scraping position under the drive of the drive conversion assembly. At least a portion of the scraper contacts the cleaning component to scrape off the attached dirt on the cleaning component.
[0061] The cleaning base station resolves the functional conflict between the entry and exit of cleaning components from the receiving cavity and the scraping cleaning process by clearly defining clean and non-clean states. In the clean state, the drive conversion component precisely rotates the scraping component to the scraping position, ensuring that the scraping component only operates when cleaning is required. This facilitates process linkage control with the base station's water supply, drainage, or drying functions, improving the overall adaptability and intelligence of the cleaning base station to different types of cleaning equipment and various usage scenarios. This mode switching requires no manual intervention, especially suitable for the autonomous return cleaning needs of intelligent cleaning equipment, enhancing the base station's automated operation efficiency and user experience.
[0062] In cleaning mode, the scraper is precisely positioned to the scraping location via the drive conversion assembly, and at least partially in direct contact with the cleaning component, forming a stable scraping pressure and contact area. On one hand, the drive conversion assembly ensures controllable rotation angle of the scraper, avoiding issues such as incomplete contact with the cleaning component or damage due to excessive contact pressure caused by positional misalignment. On the other hand, the direct contact between the scraper and the cleaning component allows for targeted removal of stubborn dirt adhering to the surface of the cleaning component. Compared to non-contact cleaning, this method more thoroughly removes residual dirt from the crevices of the cleaning component, preventing dirt from re-contaminating the ground. Simultaneously, the structure of the receiving cavity collects the scraped dirt, preventing it from scattering into the base station interior or external environment, further improving the cleaning effect.
[0063] The scraping component is integrated into the receiving cavity of the cleaning tray, eliminating the need for additional independent installation space inside the base station and significantly reducing its overall size, making it suitable for use in small spaces such as homes. Simultaneously, the transmission connection between the drive conversion component and the scraping element reduces connection gaps between components, lowering the risk of structural loosening due to vibration and impact. Furthermore, the enclosed receiving cavity environment of the scraping element in the cleaning state prevents dirt from splashing during scraping, reducing the need for cleaning and maintenance inside the base station and improving overall structural reliability.
[0064] The drive conversion component only drives the scraper to rotate when switching between non-clean and clean states. During the cleaning process, there is no need to continuously output power; it is only necessary to maintain the scraping position. Compared with the continuous drive cleaning method, this can significantly reduce the base station's energy consumption. At the same time, the mechanical scraping method of the scraper does not rely too much on consumables. Regular cleaning of the scraper and the housing cavity is sufficient, reducing the consumable replacement costs for users during long-term use.
[0065] According to a third aspect of the present invention, a cleaning control method is provided, the cleaning control method being applied to a cleaning disc and / or a cleaning base station, the cleaning disc and / or the cleaning base station including a receiving cavity and a scraping assembly, the scraping assembly being disposed within the receiving cavity, the scraping assembly including a scraping element rotatable about a first axis and a drive conversion assembly pulverizedly connected to the scraping element, the drive conversion assembly being used to convert a driving force into rotation of the scraping element about the first axis;
[0066] The cleaning control method includes:
[0067] In response to a status signal indicating that the cleaning component is located in the receiving cavity, the drive conversion assembly is controlled to drive the scraping component to the scraping position and supply water to the water inlet channel, so that the scraping component and the receiving cavity together define a water storage section for storing water; as the cleaning component rolls along the receiving cavity, the scraping component is kept in the scraping position, so that the cleaning component comes into contact with the water in the water storage section and is scraped off by the scraping component;
[0068] In response to the cleaning stop condition, the drive conversion component is controlled to drive the scraper to the avoidance position and stop supplying water to the water inlet channel, so that the water storage part is connected to the water outlet channel and the drain outlet, and the sewage in the water storage part is guided to the drain outlet through the water outlet channel and discharged.
[0069] Control the cleaning component to leave the receiving cavity;
[0070] The cleaning stop conditions include at least one of the following: the time required to reach the target cleaning time, the number of scraping operations required to reach the target time, the contact resistance or driving current between the scraping component and the cleaning component being lower than a threshold, or the contamination index based on stain / water turbidity reaching a threshold.
[0071] In response to the status signal indicating that the cleaning component is in the receiving cavity, the control drive conversion component rotates the scraper to the scraping position and supplies water to the water inlet channel. This causes the scraper and the receiving cavity to jointly define the water storage section, maintaining the scraper in the scraping position throughout the entire rolling process of the cleaning component within the receiving cavity. Thus, on the one hand, the cleaning component is continuously immersed in or in contact with the water in the water storage section during rolling, ensuring thorough wetting and softening of contaminants; on the other hand, the scraper simultaneously performs mechanical scraping of the cleaning component. The water washing and scraping actions work together to achieve a stable and reproducible scraping contact state, significantly enhancing the ability to peel and remove attached contaminants, improving cleaning effectiveness and the consistency of the cleaning process.
[0072] When the cleaning stop condition is met, the control drive conversion component rotates the scraper to the avoidance position and stops supplying water to the inlet channel. At the same time, it connects the water storage section with the outlet channel and drain, guiding the sewage in the water storage section to the drain outlet for discharge. By coordinating the switching between the scraping and avoidance positions, the water circuit status of the three stages of water storage, scraping, and drainage is clearly zoned and sequentially controlled: the cleaning stage concentrates water storage and enhances the scraping effect, while the drainage stage quickly removes highly polluted sewage from the cavity. This helps reduce sewage retention and backflow in the receiving cavity, and reduces the probability of hair, fibers, and silt accumulating in local areas, thereby effectively suppressing secondary pollution and water circuit blockage problems and improving the reliability of overall water circuit management.
[0073] The cleaning termination conditions include at least one of the following: target cleaning duration, target number of scraping operations, contact resistance or drive current between the scraper and the cleaning component falling below a threshold, and a contamination level indicator based on dirt / water turbidity reaching a threshold. By integrating time, number of actions, contact conditions (resistance / current), and water / stain status into the control logic, the system can dynamically determine when to end cleaning based on the actual cleaning load and cleaning effect: when the resistance or current decreases, indicating a reduction in attached dirt, or when the contamination level indicator reaches a preset threshold, cleaning can be terminated early to avoid unnecessary repeated scraping and water supply; when the dirt is heavy, sufficient cleaning intensity can be ensured through time or number of scraping operations. This adaptive control method improves the accuracy and repeatability of cleaning termination judgment, reduces water and energy consumption, and reduces wear on the scraper and cleaning components.
[0074] After the scraping and drainage steps are completed, the cleaning component is controlled to leave the receiving cavity. At this point, the scraping component is in a clearing position, and the wastewater in the water storage section has been drained. This prevents the cleaning component from coming into contact with highly contaminated wastewater or residual liquid again during withdrawal, thus preventing recontamination of the freshly cleaned component. It also prevents the scraping component from creating ineffective obstruction or additional friction on the cleaning component during its entry and exit, ensuring smooth movement of the cleaning component in and out of the receiving cavity and the stability of the entire machine's operation.
[0075] In some exemplary embodiments of the present invention, based on the foregoing scheme, the driving conversion component includes:
[0076] An actuator is disposed on the cleaning component;
[0077] The paddle is coaxially connected to the scraper.
[0078] One end of the transmission rod is connected to the output shaft of the actuator; the other end is in intermittent contact with the paddle.
[0079] Controlling the drive conversion component to drive the scraper to the scraping position includes:
[0080] The actuator is controlled to rotate so that the output end of the transmission rod abuts against the paddle and applies a thrust / torque to it within one working cycle;
[0081] Under the force of the paddle, the scraping element is driven to rotate around the first axis to the scraping position and remain there;
[0082] In response to the cleaning stop condition, the actuator is controlled to rotate in the opposite direction or stop, causing the output end of the transmission rod to disengage from the paddle, and the scraper to rotate to the avoidance position.
[0083] By mounting the actuator on the cleaning component and having it intermittently contact the paddle via the output end of the transmission rod during one working cycle, the continuous rotation of the actuator is converted into a directional thrust / torque on the paddle. The scraping component, coaxially connected to the paddle, then rotates around a first axis to the scraping position. This mechanical linkage structure is simple, with a clear transmission path. It can push the scraping component to the predetermined scraping position with a relatively defined stroke and angle in each working cycle, facilitating repeatable scraping actions and providing a foundation for stable and reproducible scraping contact, thus improving the problem of inconsistent cleaning results.
[0084] The output end of the drive rod only contacts the paddle and applies thrust within a specific angular range during the working cycle. After driving the scraper to the scraping position, the output end of the drive rod separates from the paddle, and the scraper can be held in the predetermined position. This intermittent contact design avoids the actuator continuously applying torque to the scraper throughout the cleaning process, reducing unnecessary friction and clamping force, lowering wear and energy consumption of the actuator and drive components, which helps extend the service life of the drive conversion assembly and improve the overall reliability of the machine.
[0085] In response to the cleaning stop condition, the actuator is controlled to rotate in the opposite direction or stop, causing the output end of the transmission rod to disengage from the paddle, thereby releasing the drive constraint on the paddle and the scraper, allowing the scraper to rotate to an avoidance position. This ensures that the scraper is kept away from the path of the cleaning component during the non-cleaning phase, preventing the cleaning component from being blocked or scratched by the scraper when entering or leaving the receiving cavity, reducing mechanical interference and noise. Furthermore, it reduces the continuous accumulation time of hair and fibrous contaminants in the scraping area, and combined with water drainage, helps reduce the risk of entanglement and secondary contamination.
[0086] The actuator is mounted on the cleaning component and transmits driving force through intermittent contact between the drive rod and the paddle inside the cleaning tray. This eliminates the need for complex motors and long-term exposed electrical connections within the cleaning tray, shortening the signal and power transmission links, simplifying the internal structural layout of the cleaning tray, and improving its waterproof, anti-fouling, and sealing performance. Consequently, the interaction between the cleaning component and the cleaning tray is more modular, facilitating assembly and maintenance, and contributing to improved overall stability in long-term wet and dirty environments.

Detailed Implementation
[0101] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0102] The features, structures, or characteristics described above can be combined in any suitable manner in one or more embodiments, and the features discussed in the various embodiments are interchangeable where possible. In the above description, numerous specific details are provided to give a full understanding of embodiments of the invention. However, those skilled in the art will recognize that the technical solutions of the invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the invention.
[0103] Although relative terms such as "up" and "down" are used in this invention to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the icon's arrangement is flipped so that it is upside down, the component described as "up" will become the component described as "down". Other relative terms such as "high", "low", "top", "bottom", "front", "back", "left", and "right" also have similar meanings. When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.
[0104] In this invention, the terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising,” “including,” and “having” are used to indicate an open-ended inclusion meaning and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.
[0105] In existing technologies, cleaning base stations or cleaning discs mostly employ fixed scrapers or passive contact scraping structures to simply scrape away dirt from the cleaning components. The scraping contact state is greatly affected by the orientation of the cleaning component and changes in water volume, leading to unstable cleaning results and difficulty in ensuring consistent cleaning across multiple uses. This results in fluctuations in the removal of dirt from the surface of the cleaning components, resulting in inconsistent cleaning performance. Furthermore, existing solutions have relatively crude organization and management of the water channels within the receiving cavity. Hair and fibrous dirt generated during the cleaning process easily accumulate and entangle near the scrapers and blades, affecting the normal operation of the scraping structure. Simultaneously, wastewater and residual liquid may stagnate or backflow in localized areas, easily causing secondary contamination of the cleaning components and the inner wall of the cavity.
[0106] According to one aspect of the invention, reference is made to Figures 1 to 7 As shown, a cleaning disc 10 is provided. The cleaning disc 10 can be a separately installed structural component for cleaning the cleaning components 20 in the cleaning equipment, or it can be a structural component installed on the cleaning base station or the cleaning robot body for cleaning the cleaning components 20 in the cleaning equipment. Here, the cleaning equipment can be a sweeping robot, a floor scrubber, a steam mop, a handheld vacuum cleaner with a roller attachment, a mite remover, etc., and the cleaning component 20 can be a roller brush, a rubber brush, a roller mop, or other strip / cylindrical cleaning components that can rotate around their own axis.
[0107] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the cleaning tray 10 includes a cleaning surface, on which a receiving cavity 11 for accommodating the cleaning component 20 is formed. The opening of the receiving cavity 11 faces the cleaning equipment side, so that the cleaning component 20 can be partially or completely inserted into the receiving cavity 11 during cleaning. The cleaning tray 10 can be a one-piece injection molded part or assembled from an upper cover and a lower shell. Guide ribs, limiting surfaces, and other structures can be provided on the circumferential wall of the receiving cavity 11 as needed to constrain the position of the cleaning component 20.
[0108] refer to Figure 2 and Figure 3 As shown, the scraping assembly 12 is disposed within the receiving cavity 11. The scraping assembly 12 includes a scraping member 121 rotatable about a first axis X1 and a drive conversion assembly 122 pulsatingly connected to the scraping member 121. The first axis X1 may be arranged parallel or intersecting the axis of the receiving cavity 11. In this embodiment, it is preferable to set the first axis X1 to be approximately parallel to the axis of the cleaning member 20, so that the scraping member 121 can move closer to or away from the outer peripheral surface of the cleaning member 20 in a swinging manner.
[0109] refer to Figure 3As shown, in the scraping position, the scraper 121 rotates about the first axis X1 to the side close to the cleaning member 20, with its working edge protruding towards the interior of the receiving cavity 11 and contacting the outer periphery of the cleaning member 20 that extends into the receiving cavity 11. During the rotation of the cleaning member 20 about the first axis or the rolling along the receiving cavity 11, the working edge of the scraper 121 mechanically scrapes away hair, fibers, and stains adhering to the surface of the cleaning member 20.
[0110] In the avoidance position, the scraper 121 rotates around the first axis X1 to the side away from the receiving cavity 11 under the action of the drive conversion assembly 122, so that at least the working edge or most of the length of the scraper 121 reduces the motion interference with the cleaning component 20.
[0111] When the cleaning component 20 returns to the compartment or passes the cleaning disc 10, the drive conversion assembly 122 can drive the scraper 121 to the scraping position to scrape and clean the cleaning component 20. After cleaning is completed, the drive conversion assembly 122 can drive the scraper 121 to the clearance position so that the cleaning component 20 leaves the receiving cavity 11, completing one self-cleaning cycle.
[0112] Based on this, a water inlet channel 13 is provided on the cleaning tray 10. One end of the water inlet channel 13 is connected to an external water supply port, and the other end is connected to the receiving cavity 11 for supplying water into the receiving cavity 11.
[0113] When the scraper 121 is in the scraping position, the surface of the scraper 121 near the receiving cavity 11 forms a partially recessed space with the bottom wall and / or side wall of the receiving cavity 11. This recessed space constitutes the water storage section 16 for storing water. Specifically, after the scraper 121 is rotated to the scraping position, its working edge moves away from the bottom of the receiving cavity 11 and cooperates with the flange, sidewall or side wall of the bottom of the receiving cavity 11 to define a closed or semi-closed volume area. The outlet of the water inlet channel 13 is arranged facing this area, so that external water supply flows into the water storage section 16 through the water inlet channel 13 and forms a water layer or pool of a certain height in the water storage section 16.
[0114] When the cleaning component 20 is in cleaning mode, at least a portion of the cleaning component 20 extends into the receiving cavity 11, and a section of its outer periphery is located within the space of the water storage section 16. As the cleaning component 20 rotates around its own axis or rolls along the receiving cavity 11, the outer peripheral surface of the cleaning component 20 first comes into contact with the water in the water storage section 16, and the attached dust, mud, and hair are wetted and softened. Then, this part of the surface passes the working edge of the scraper 121 at the scraping position, and the scraper 121 mechanically scrapes the outer periphery of the cleaning component 20, peeling off the softened dirt and carrying it into the water in the water storage section 16. Through the combination of the water washing action in the water storage section 16 and the mechanical scraping action of the scraper 121, a more thorough and stable removal of dirt from the surface of the cleaning component 20 can be achieved.
[0115] In addition, refer to Figures 4 to 6 As shown, in some embodiments, the cleaning tray 10 is also provided with a water outlet channel 14 and a drain outlet 15. One end of the water outlet channel 14 is connected to the drain outlet 15, which is preferably located on the cleaning surface to facilitate the discharge of sewage out of the cleaning tray 10; the other end of the water outlet channel 14 is located in the receiving cavity 11 to discharge sewage from the receiving cavity 11 during drainage.
[0116] When the scraper 121 is in the scraping position, it is located in the receiving cavity 11. Its edge facing the bottom of the receiving cavity 11 engages with the limiting flange and sidewall on the bottom and / or sidewall of the receiving cavity 11, dividing the receiving cavity 11 into an independent water storage section 16 and a drainage section 17 along the rolling direction of the cleaning component 20. Specifically, the area near the water inlet channel 13 forms the water storage section 16, which is used to store clean water or cleaning fluid flowing in from the water inlet channel 13 during the cleaning process. The area outside the water storage section 16 and near the opening of the water outlet channel 14 forms the drainage section 17. At this time, the water storage section 16 and the drainage section 17 are basically not connected, so that the water in the water storage section 16 is concentrated and retained on the scraper 121 side, which is beneficial to maintain sufficient water depth for the cleaning component 20 to soak and scrape during the cleaning stage.
[0117] When drainage is required, the scraper 121 rotates to a clearance position. In this position, the scraper 121 rotates around the first axis X1 away from the limiting flange area that originally formed a sealing fit with the bottom wall and side wall of the receiving cavity 11, so that the water storage part 16 and the drainage part 17, which were originally separated by the scraper 121, form a communication channel below or to the side of the scraper 121; at the same time, the water storage part 16 and the drainage part 17 are connected to the water outlet channel 14, and the water outlet channel 14 is further connected to the drain outlet 15, so that the water storage part 16, the drainage part 17, the water outlet channel 14 and the drain outlet 15 sequentially form a continuous drainage path.
[0118] refer to Figure 4 As shown, the scraping element 121 is a solid line when in the scraping position and a dashed line when in the avoidance position. Alternatively, refer to... Figure 5 The diagram shown is a structural schematic of the scraping component at the scraping location. Figure 6 This is a structural diagram of the scraping component in the avoidance position.
[0119] During drainage, the wastewater in the water storage section 16 flows towards the drainage section 17 along the surface or edge of the scraper 121 under the action of gravity. To guide the flow of wastewater, the side of the scraper 121 facing the drainage section 17 is preferably provided with a guide surface at a certain angle, with the lower end of the guide surface adjacent to the location of the drainage section 17; the bottom wall of the receiving cavity 11 may be partially recessed or provided with a guide groove near the drainage section 17 to collect wastewater from the water storage section 16. In this way, the wastewater in the water storage section 16 slides down the guide surface of the scraper 121 to the drainage section 17, then enters the water outlet channel 14 through the opening at the bottom of the drainage section 17, and finally is discharged from the cleaning tray 10 through the drain outlet 15.
[0120] In some embodiments, the relative height relationship of the drainage section 17, the water outlet channel 14, and the drain outlet 15 is optimized along the height direction X of the cleaning tray 10.
[0121] Specifically, the bottom surface of the receiving cavity 11 used to form the drain section 17 is set at a first height H1, the bottom surface of the water outlet channel 14 is set at a second height H2, and the lower edge of the drain outlet 15 is set at a third height H3, where H1>H2>H3. That is to say, along the height direction X (from top to bottom) of the cleaning tray 10, the bottom surface of the drain section 17, the bottom surface of the water outlet channel 14, and the opening position of the drain outlet 15 are arranged sequentially, so that the drain section 17, the water outlet channel 14, and the drain outlet 15 form a gradually decreasing height difference in the vertical direction.
[0122] Structurally, the bottom wall of the shell in the area where the drainage section 17 is located can be slightly arched or raised relative to the water outlet channel 14 to form a step. The water outlet channel 14 is arranged below or to the side of this step and extends slightly inclined along the direction of gravity to the drain outlet 15. The opening height of the drain outlet 15 is lower than the bottom surface of the water outlet channel 14 to form the final discharge position. In this way, when the scraper 121 is turned to the avoidance position and the water storage section 16 is connected to the drainage section 17, the water outlet channel 14, and the drain outlet 15 in sequence, the sewage in the drainage section 17 flows along the bottom surface of the drainage section 17 to the water outlet channel 14 under the action of gravity, and then flows naturally along the bottom surface of the water outlet channel 14 to the drain outlet 15, and finally is discharged from the cleaning tray 10 through the drain outlet 15. The gravity drainage process can be completed without the need for an additional pumping mechanism.
[0123] In some embodiments, to further guide the sewage flow to the inlet of the effluent channel 14, refer to Figure 4 and Figure 6As shown, the bottom surface of the drainage section 17 can be designed as a sloped surface with a certain gradient, and its lowest point corresponds to the inlet position of the water outlet channel 14; the bottom surface of the water outlet channel 14 can also be set to be slightly inclined towards the drain outlet 15 to reduce sewage retention. At the same time, since the bottom surface of the drainage section 17 is higher than the bottom surface of the water outlet channel 14, and the bottom surface of the water outlet channel 14 is higher than the opening of the drain outlet 15, the risk of sewage backflow or local accumulation can be reduced, making it easier for sewage to be discharged in a concentrated manner, which facilitates subsequent drying of the inside of the cleaning tray 10 and inhibition of odor and bacterial growth.
[0124] In some implementations, reference Figure 4 As shown, the water inlet channel 13 and the water outlet channel 14 are arranged in layers along the height direction X of the cleaning tray 10. Specifically, the bottom surface of the water inlet channel 13 is set above the bottom surface of the water outlet channel 14, that is, the water inlet channel 13 is located near the upper part of the receiving cavity 11, and the water outlet channel 14 is located relatively closer to the bottom of the cleaning tray 10. On the one hand, through the above-mentioned layered arrangement, the water supply path and the drainage path are clearly separated in space. The water inlet channel 13 supplies water to the water storage section 16 at a higher position, and the water outlet channel 14 drains water from the drainage section 17 at a lower position. This is beneficial for maintaining the water volume in the water storage section 16 under cleaning conditions, and for smoothly completing the gravity discharge of sewage under drainage conditions. On the other hand, combining the previous gravity drainage design where the bottom surface of the drainage section 17 > the bottom surface of the outlet channel 14 > the opening of the drain outlet 15, placing the inlet channel 13 above the outlet channel 14 allows the flow of clean water and sewage to follow independent logics of top-down water supply and high-to-low drainage, respectively. Clean water in the inlet channel 13 can flow naturally into the lower water storage section 16 by gravity without additional power (e.g., the outlet of the inlet channel 13 directly connects to the top of the water storage section 16), simplifying the water supply structure. Simultaneously, the outlet channel 14, located at a lower position, can more smoothly receive sewage from the drainage section 17 and guide it to the drain outlet 15. The height arrangement of both perfectly matches the direction of gravity, avoiding blockages or flow obstruction caused by conflicting water flow directions, thus improving the overall efficiency of water supply and drainage. This invention does not limit the specific height difference between the inlet channel 13 and the outlet channel 14; those skilled in the art can set it according to actual conditions.
[0125] In addition, in some implementations, references Figure 1 , Figure 2 , Figures 4 to 7As shown, an isolation element 18 can also be installed within the outlet channel 14. The design of the isolation element 18 can be adapted to the shape of the outlet channel 14 (such as channel width, direction, and height gradient), for example, by adopting a grid-type or mesh-type structure. This ensures filtration accuracy while reserving sufficient water flow channels, preventing a significant increase in drainage resistance due to the installation of the isolation element 18. Furthermore, some isolation elements 18 can be designed as inclined or arc-shaped structures, which not only intercept impurities but also assist in guiding the flow of wastewater, directing it smoothly along the height gradient of the outlet channel 14. This ensures that the filtration function is achieved without affecting wastewater discharge efficiency, thus balancing the dual requirements of filtration protection and efficient drainage.
[0126] In an embodiment of the present invention, reference Figure 1 , Figure 2 , Figures 4 to 7 As shown, there are multiple isolation elements 18, which are spaced apart along the cross-section of the outlet channel 14. Specifically, the cross-section of the outlet channel 14 can be approximately rectangular or elliptical. The multiple isolation elements 18 are arranged in the form of plates, ribs, or columns within the outlet channel 14. One or both ends of each isolation element 18 are fixedly connected to the inner wall of the outlet channel 14, for example, to opposite side walls, or extending from the bottom wall to the top wall, thus dividing the cross-section of the outlet channel 14 into several parallel flow sub-channels. A gap is reserved between adjacent isolation elements 18 for sewage to pass through, ensuring the overall flow capacity.
[0127] In some embodiments, multiple separators 18 are arranged at equal intervals along the cross-sectional direction of the outlet channel 14, and the height of the separators 18 is higher than the inner cavity height of the outlet channel 14, so that the sewage is distributed into multiple sub-channels when flowing through the outlet channel 14. With the above structural arrangement, even if hair, fibers or large particulate impurities are entangled or accumulated in a certain sub-channel, the other sub-channels can still remain unobstructed, thereby reducing the risk of the entire outlet channel 14 being completely blocked, and facilitating the smooth flow of subsequent sewage through the outlet channel 14 to the drain outlet 15 for discharge.
[0128] In some embodiments, the scraper 121 can be a strip-shaped or sheet-like structure, with working edges or ribs along its length that mate with the outer periphery of the cleaning component 20. The middle portion of the scraper 121 is supported on the housing by a pivot, hinge hole, or bushing, allowing it to rotate about the first axis X1. One end or the middle portion of the scraper 121 may be provided with reinforcing ribs, limiting protrusions, or other structures to engage with limiting surfaces on the housing in the scraping or avoidance positions, thereby limiting its rotation range.
[0129] In some implementations, reference Figure 8As shown, the scraping member 121 may include a rotating shaft 1211 and a scraping part 1212. The axis of the rotating shaft 1211 is a first axis X1. The scraping part 1212 has a first end 1212a connected to the rotating shaft 1211 and a second end 1212b away from the first end 1212a. That is, in this embodiment, the second end 1212b of the scraping part 1212 is a working edge or working rib that matches the outer periphery of the cleaning member 20. Along the first axis X1, both ends of the rotating shaft 1211 are rotatably supported on bearing seats or support ears of the cleaning disc 10 housing, so that the scraping member 121 as a whole can rotate relative to the housing about the first axis X1. The scraping part 1212 can be a plate-shaped, arc-shaped, or sheet-shaped structure with reinforcing ribs. Its first end 1212a is fixed to the rotating shaft 1211 by overmolding, snap-fitting, or fasteners, or is integrally injection molded with the rotating shaft 1211, so that the scraping part 1212 rotates together with the rotating shaft 1211.
[0130] In the scraping position, the drive conversion assembly 122 rotates the scraper 121 to the side facing the cleaning component 20. The scraper 1212 is tilted towards the cleaning component 20, and its second end 1212b extends into the cleaning component 20 and contacts its outer peripheral surface. At this time, as the cleaning component 20 rotates under its own drive or rolls along the receiving cavity 11, its outer peripheral surface passes sequentially through the water storage part 16 and the second end 1212b of the scraper 1212, and the second end 1212b scrapes the outer periphery of the cleaning component 20.
[0131] In the avoidance position, the scraper 121 rotates around the first axis X1 to the side away from the cleaning member 20, so that the scraper 1212 is away from the path of the cleaning member 20, and at the same time, a drainage channel is formed between the scraper 1212 and the bottom surface of the water storage part 16. Specifically, when the scraper 1212 is in the avoidance position, the plane between the first end 1212a and the second end 1212b of the scraper 1212 is formed as a guide plane. This guide plane is nearly parallel to the bottom surface of the water storage part 16, or the angle between the guide plane and the bottom surface of the water storage part 16 is changed to an obtuse angle, so that the water in the water storage part 16 can flow out of the water storage part 16 through the bottom surface of the water storage part 16 and the guide plane.
[0132] After the scraper 121 moves from the scraping position to the avoidance position, and the water storage section 16, drainage section 17, water outlet channel 14, and drain outlet 15 are connected, the sewage in the water storage section 16 flows from the water storage section 16 to the drainage section 17 under the action of gravity through the diversion channel. Preferably, the bottom surface of the water storage section 16 can be designed to be slightly inclined towards the drainage section 17. When the scraper 1212 is in the avoidance position, its side facing the water storage section 16 is arranged opposite to the inclined bottom surface. The diversion channel guides the sewage in the water storage section 16 to flow to the drainage section 17 along the gap between the scraper 1212 and the bottom surface of the water storage section 16, thereby realizing at least a partial diversion of the sewage in the water storage section 16.
[0133] The drive conversion assembly 122 is located near the pivoting area of the scraper 121. (Reference) Figures 1 to 3 As shown, the drive conversion assembly 122 converts the driving force into the rotation of the scraper 121 around the first axis X1, allowing the scraper 121 to switch between a scraping position and an avoidance position. Since the drive conversion assembly 122 is abstracted as a mechanism for converting the driving force into the rotation of the scraper 121 around the first axis, it can be adapted to different types of drive sources, such as rotary drive or linear drive. This allows for flexible structural arrangement without changing the working mode of the scraper 121, facilitating a more compact design of the overall structure of the cleaning disc 10, reducing the number of independent drive components, thereby reducing potential failure points and improving the working stability and service life of the scraper assembly 12.
[0134] In some embodiments, the drive conversion assembly 122 can be any of a variety of forms such as a cam-follower mechanism, a rocker arm mechanism, a linkage mechanism, or a gear / sector gear. The external driving force can be a rotational force, a reciprocating linear force, or a oscillating force. The drive conversion assembly 122 converts the above driving force into a limiting oscillation of the scraper 121 around the first axis X1, thereby realizing the switching between the scraping position and the avoidance position.
[0135] In other embodiments, the drive conversion assembly 122 may adopt a mechanical transmission form of actuator 1221-paddle 1222-drive rod 1223. Specifically, as Figures 1 to 3 As shown, the actuator 1221 is mounted on the cleaning component 20, for example, within the end bracket of the roller mop. The actuator 1221 can be a small motor, a geared motor, a mechanical linkage driven by the traveling mechanism of the cleaning equipment, or other drive elements capable of outputting rotational power. The output shaft of the actuator 1221 is arranged along the axis of the cleaning component 20 or at a predetermined angle to the axis of the cleaning component 20. Its output shaft is connected to one end of the transmission rod 1223 via a spline, key, or connecting seat, thereby driving the transmission rod 1223 to move when the actuator 1221 rotates.
[0136] refer to Figure 8 As shown, the paddle 1222 is coaxially connected to the scraper 121. Specifically, the paddle 1222 is fixed on the rotating shaft 1211 of the scraper 121. The paddle 1222 can be a plate-shaped or fan-shaped structure extending radially. Its central hole is fixed to the rotating shaft 1211 by interference fit, spline connection, or threaded connection, so that the paddle 1222 and the scraper 121 remain coaxial in the first axial direction and form a rigid component that rotates integrally. The outer edge or side of the paddle 1222 is provided with an abutment surface that mates with the other end of the transmission rod 1223. For example, it can be set as an arc surface, a slope, or a partial boss, for being pushed by the transmission rod 1223 when the transmission rod 1223 moves to a predetermined angle.
[0137] One end of the transmission rod 1223 is connected to the output shaft of the actuator 1221, and the other end is located near the movement path of the paddle 1222, and intermittently contacts the paddle 1222. Preferably, the transmission rod 1223 can be oscillating around its own axis or around a fixed fulcrum. During the rotation of the actuator 1221, the output end of the transmission rod 1223 oscillates or rotates along a preset trajectory. When the output end of the transmission rod 1223 moves to the angle region where the paddle 1222 is located, its end contacts the abutment surface of the paddle 1222 and applies a pushing force or torque to the paddle 1222; when the output end of the transmission rod 1223 rotates out of the angle region, it separates from the paddle 1222 and no longer applies force to the paddle 1222.
[0138] With the above-described structure, the continuous rotation of actuator 1221 is converted into a reciprocating thrust on paddle 1222 via transmission rod 1223. Whenever the output end of transmission rod 1223 abuts against paddle 1222 and applies a thrust, paddle 1222 rotates around the first axis under this thrust, causing the coaxially connected scraper 121 to rotate around the first axis as well. This drives the scraper 121 from the avoidance position to the scraping position, or from the scraping position to the avoidance position. By rationally designing the shape of paddle 1222, the trajectory of the output end of transmission rod 1223, and the contact angle range between them, the scraper 121 can complete one or more reciprocating oscillations within one or more actuator 1221 working cycles, allowing the scraper 121 to switch back and forth between the scraping position and the avoidance position.
[0139] In some embodiments, a torsion spring, tension spring, or other reset elastic element can be provided on the scraper 121 or the rotating shaft 1211 to provide a reset torque for the scraper 121 when the output end of the transmission rod 1223 separates from the paddle 1222. For example, when the actuator 1221 rotates forward, the output end of the transmission rod 1223 applies a pushing force to the paddle 1222 within a specific angle range, pushing the scraper 121 to the scraping position; when the actuator 1221 stops or rotates in the reverse direction, and the output end of the transmission rod 1223 disengages from the paddle 1222, the scraper 121 automatically rotates to the avoidance position under the action of the reset elastic element. Through the above mechanical coordination, the scraper 121 can automatically and repeatedly switch between the scraping position and the avoidance position according to the rotation of the actuator 1221 without adding complex control algorithms, ensuring that the scraping action and drainage / avoidance action in the cleaning process have good mechanical repeatability and reliability.
[0140] Based on this, refer to Figures 1 to 3As shown, actuator 1221 is mounted on cleaning component 20, and its output shaft is arranged along the axial direction of cleaning component 20 or parallel to the axis of cleaning component 20. A first gear 1221a is fixedly sleeved on the outer periphery of the output shaft of actuator 1221. The first gear 1221a is coaxial with the output shaft of actuator 1221, and its axis is parallel to the aforementioned first axis. The first gear 1221a can be fixed on the output shaft by spline fit, key connection, or interference fit, so that the output torque of actuator 1221 can be transmitted to the first gear 1221a without loss.
[0141] The transmission rod 1223 is arranged on the housing of the cleaning disc 10 or a corresponding bracket, and its axis is perpendicular to the first axis. The transmission rod 1223 is provided with a second gear 1223a that meshes with the first gear 1221a. The second gear 1223a is coaxially mounted with the transmission rod 1223, and its axis is perpendicular to the first axis. The second gear 1223a is fixed to the transmission rod 1223 by means of a key connection, a slot, or a thread, or as... Figure 3 As shown, a second gear 1223a is engraved at the end of the transmission rod 1223. The tooth surface of the second gear 1223a extends along the axial direction of the transmission rod 1223 and faces the first gear 1221a, making the second gear 1223a and the transmission rod 1223 an integral structural component. When the actuator 1221 is working, its output shaft drives the first gear 1221a to rotate. The first gear 1221a and the second gear 1223a mesh with each other through their tooth surfaces, reliably transmitting the torque output by the actuator 1221 to the second gear 1223a, thereby driving the transmission rod 1223 to move along its own axial direction.
[0142] With the above arrangement, the rotation direction of the actuator 1221 output shaft changes spatially through the meshing of the first gear 1221a and the second gear 1223a: the axis of the actuator 1221 output shaft is parallel to the first axis, while the axis of the transmission rod 1223 is perpendicular to the first axis. By means of the orthogonal meshing of the two gears, the torque direction can be reversed within a limited space, while maintaining transmission efficiency and meshing accuracy. The end of the transmission rod 1223 away from the second gear 1223a continues to intermittently contact the paddle 1222 and apply a thrust / torque to it, thereby driving the paddle 1222 and the coaxial scraper 121 to reciprocate around the first axis, realizing the switching between the scraping position and the avoidance position.
[0143] In some implementations, reference Figure 8 and Figure 9As shown, the scraping member 121 includes a scraping portion 1212 extending radially toward the cleaning member 20 and a paddle 1222 coaxially disposed with the scraping member 121. The paddle 1222 is fixedly mounted on the rotating shaft 1211, and its entirety is generally located in a reference plane; the scraping portion 1212 and the paddle 1222 are not coplanar, but rather have a predetermined included angle relative to the paddle 1222 about the rotating shaft 1211. Preferably, when the scraping member 121 is in the intermediate position or any predetermined reference position, the included angle α between the scraping portion 1212 and the paddle 1222 is limited to 40° to 50°, for example, it can be 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, or 50°; more preferably, it is 45°.
[0144] In other words, the included angle α formed by rotating the pivot 1211 from the reference plane of the paddle 1222 toward the reference plane of the scraping part 1212 is 40° to 50°. This angle design ensures that, on the one hand, when the paddle 1222 is subjected to the thrust of the transmission rod 1223 and rotates at a certain angle, it can drive the scraping part 1212 to generate sufficient swing stroke through a reasonable lever arm relationship, thus achieving reliable switching between the scraping position and the avoidance position. On the other hand, while ensuring power transmission efficiency, it avoids insufficient stroke due to an excessively small relative angle between the paddle 1222 and the scraping part 1212, or excessive structural interference and excessive space occupation due to an excessively large relative angle, which is beneficial for achieving a compact arrangement and stable transmission within a limited installation space.
[0145] In some implementations, reference Figure 8 As shown, the drive conversion assembly 122 includes a stop portion 1224. Specifically, as... Figure 8 As shown, the rotating shaft 1211 of the scraper 121 extends along the first axis. The paddle 1222 is disposed at the end of the scraper 121 near the cleaning component 20 and is coaxially fixed with the rotating shaft 1211. The abutment 1224 is also coaxially disposed with the scraper 121 and is arranged at the other end of the scraper 121 away from the paddle 1222 along the first axis. That is, the paddle 1222 and the abutment 1224 are respectively located at both ends of the scraper 121 along the first axis. One end is used to intermittently cooperate with the transmission rod 1223 to achieve driving, and the other end is used to cooperate with the housing limiting structure to achieve position limitation.
[0146] The abutment 1224 can be a radially extending plate or disc, with its central hole fixedly connected to the rotation shaft 1211 of the scraper 121. Preferably, at least one abutment surface is formed on the outer edge of the abutment 1224. When the scraper 121 is rotated to the avoidance position by the drive conversion assembly 122, the abutment surface abuts against the cleaning surface on the cleaning disc 10 housing, thereby limiting the maximum rotation angle of the scraper 121 in the avoidance position. By arranging the paddle 1222 and the abutment 1224 at the two ends of the scraper 121 along the first axis, one end realizes the input of driving force, and the other end realizes mechanical limitation, not only is the structure of the drive conversion assembly 122 more compact and the force transmission path clearer, but it can also stably and repeatably limit the scraping position and the avoidance position, prevent the scraper 121 from rotating excessively and reduce interference with the cleaning surface, the bottom surface of the drain 17 or the bottom surface of the water outlet channel 14, thus affecting the flow of sewage from the drain 17 to the water outlet channel 14.
[0147] refer to Figure 9 As shown, the scraping part 1212 and the blocking part 1224 are not completely on the same plane, but form a small angle. The angle β between the scraping part 1212 and the blocking part 1224 is set to 3° to 7°. That is, the angle β obtained by rotating about the rotation axis 1211 from the reference plane of the blocking part 1224 to the reference plane of the scraping part 1212 is 3° to 7°. For example, it can be 3 degrees, 4 degrees, 5 degrees, 6 degrees, or 7 degrees.
[0148] According to a second aspect of the present invention, a cleaning base station is provided, which is used at least for cleaning cleaning components 20 in a cleaning device. The cleaning base station may include a docking area for docking with the cleaning device and a cleaning tray 10 disposed below or inside the docking area.
[0149] The cleaning disk 10 can be any of the cleaning disks described above, which will not be elaborated upon here. In addition, the cleaning base station has two operating modes: a clean state and a non-clean state.
[0150] In the non-cleaning state, the scraper 121 is held in a clearance position by the drive conversion assembly 122 or by the reset elastic element / gravity. In the clearance position, the scraper 121 is away from the main receiving space of the receiving cavity 11, and its scraping part 1212 is away from the entry and exit path of the cleaning component 20. This allows the cleaning component 20 to smoothly cross or pass through the cleaning tray 10 when returning to the compartment, exiting the compartment, or simply parking for charging, without being blocked or stuck by the scraper 121. This ensures the docking accuracy and smooth entry and exit between the cleaning equipment and the cleaning base station.
[0151] In the cleaning state, the cleaning equipment is guided to the docking area, and at least a portion of the cleaning component 20 on the cleaning equipment extends into the receiving cavity 11. After the base station control unit detects the status signal of the cleaning component 20 being in place, it controls the drive conversion component 122 to work, converting the external driving force into the rotation of the scraping component 121 around the first axis X1, driving the scraping component 121 to rotate from the avoidance position to the scraping position. In the scraping position, at least a portion of the scraping part 1212 of the scraping component 121 contacts the outer peripheral surface of the cleaning component 20. When the cleaning component 20 rotates or rolls along the receiving cavity 11 under its own drive or the base station drive, the scraping component 121 scrapes off the dirt attached to the surface of the cleaning component 20, realizing the active self-cleaning of the cleaning component 20.
[0152] According to a third aspect of the present invention, a cleaning control method is provided, which is applied to a cleaning disk 10 and / or a cleaning base station. The cleaning disk 10 and / or the cleaning base station can be any type of cleaning disk 10 and / or cleaning base station, or it can be the cleaning disk 10 and / or cleaning base station described above. The present invention does not impose any specific limitations.
[0153] The cleaning tray 10 has a receiving cavity 11, a scraping assembly 12, a water inlet channel 13, a water outlet channel 14, and a drain outlet 15. The scraping assembly 12 is disposed in the receiving cavity 11. The scraping assembly 12 includes a scraping element 121 that can rotate around a first axis and a drive conversion assembly 122 that is drively connected to the scraping element 121. The drive conversion assembly 122 is used to convert the driving force into the rotation of the scraping element 121 around the first axis.
[0154] Based on this, refer to Figure 10 As shown, the cleaning control methods include:
[0155] S1010: In response to the status signal that the cleaning member 20 is located in the receiving cavity 11, the drive conversion assembly 122 is controlled to drive the scraper 121 to the scraping position and supply water to the water inlet channel 13, so that the scraper 121 and the receiving cavity 11 together define the water storage part 16 for storing water; during the process of the cleaning member 20 rolling along the receiving cavity 11, the scraper 121 is kept in the scraping position, so that the cleaning member 20 comes into contact with the water in the water storage part 16 and is scraped by the scraper 121;
[0156] S1020: In response to the cleaning stop condition, the control drive conversion component 122 drives the scraper 121 to the avoidance position and stops supplying water to the water inlet channel 13, so that the water storage 16 is connected to the water outlet channel 14 and the drain outlet 15, and the sewage in the water storage 16 is guided to the drain outlet 15 through the water outlet channel 14 for discharge.
[0157] S1030: Control the cleaning component 20 to leave the receiving cavity 11.
[0158] In S1010, in response to the status signal that the cleaning member 20 is located in the receiving cavity 11, the control drive conversion assembly 122 drives the scraper 121 to the scraping position and supplies water to the water inlet channel 13, so that the scraper 121 and the receiving cavity 11 together define the water storage part 16 for storing water; during the process of the cleaning member 20 rolling along the receiving cavity 11, the scraper 121 is kept in the scraping position, so that the cleaning member 20 comes into contact with the water in the water storage part 16 and is scraped by the scraper 121.
[0159] The present invention can obtain the status signal of the cleaning component 20 in the receiving cavity 11 in a variety of ways, such as: setting a limit switch, Hall switch or reed switch at the entrance of the receiving cavity 11, and outputting a trigger signal when the cleaning component 20 or its support is pressed down / approaches; detecting the presence of the surface of the cleaning component 20 or the support by a photoelectric sensor; or determining that it has stopped at a specified position by the position sensor, encoder or other means of the cleaning equipment, and thereby determining that the cleaning component 20 has entered the receiving cavity 11.
[0160] In response to a status signal indicating that the cleaning component 20 is located in the receiving cavity 11, a control command is sent to the drive conversion assembly 122. The drive conversion assembly 122 converts the driving force into rotation of the scraping component 121 around a first axis, causing the scraping component 121 to rotate from a clearance position to a scraping position. In the scraping position, the side of the scraping component 121 near the bottom of the receiving cavity 11 encloses the bottom wall and / or side wall of the receiving cavity 11, forming a partially recessed space, which serves as a water storage section 16 for water storage.
[0161] At the same time, the water supply element connected to the water inlet channel 13 is activated, such as by opening a solenoid valve or starting a small water pump. Clean water or cleaning fluid flows into the water storage section 16 through the water inlet channel 13, forming a water layer of a certain height in the area of the water storage section 16. At this time, a portion of the outer periphery of the cleaning component 20 extending into the receiving cavity 11 is located within the space of the water storage section 16.
[0162] As the cleaning component 20 rolls along the receiving cavity 11 or rotates about its own axis, the scraping component 121 remains in the scraping position. The outer peripheral surface of the cleaning component 20 passes sequentially over the water reservoir 16 and the working edge of the scraping component 121 in one rotation cycle or multiple reciprocating strokes.
[0163] When the cleaning part 20 rotates above the water storage section 16, its outer peripheral surface comes into full contact with the water in the water storage section 16, and the attached dust, mud and hair are soaked and softened.
[0164] The surface then continues to rotate to the position of the scraper 121, where the working edge of the scraper 121 mechanically scrapes the surface of the cleaning component 20, peeling off the softened dirt and bringing it into the water body of the water storage section 16.
[0165] In S1020, in response to the cleaning stop condition, the control drive conversion component 122 drives the scraper 121 to the avoidance position and stops supplying water to the water inlet channel 13, so that the water storage section 16 is connected to the water outlet channel 14 and the drain outlet 15, and the sewage in the water storage section 16 is guided to the drain outlet 15 through the water outlet channel 14 and discharged.
[0166] During the cleaning process, the cleaning status is continuously monitored, and the cleaning is terminated based on pre-set cleaning stop conditions. Cleaning stop conditions may include at least one of the following:
[0167] Reaching the target cleaning time: For example, if the cleaning time is set to T1, the system accumulates the cleaning time through a timer. When the cleaning time reaches T1, it is considered that the cleaning intensity has met the requirements.
[0168] Reaching the target number of scraping cycles: The cleaning ends after the preset number N1 is reached by monitoring the rotation speed of the cleaning component 20 or the number of scraping cycles participated in by the scraping component 121.
[0169] Contact resistance or driving current below the threshold: By monitoring the changes in motor current, torque or speed of the driving cleaning component 20, when the contact resistance between the scraping component 121 and the cleaning component 20 decreases to below the preset threshold (indicating a significant reduction in attached dirt), it is determined that the cleaning is basically completed.
[0170] Pollution level indicator reaches threshold: Turbidity sensor, color sensor or other water quality detection element is arranged in the drainage path or water storage section 16. When the pollution level indicator based on stains / water turbidity reaches the preset threshold (for example, the cleaning water changes from "extremely dirty" to "slightly turbid" or "close to clear water"), the cleaning effect is considered to have met the standard.
[0171] Once the cleaning stop condition is met, the control drive conversion component 122 operates, causing the scraper 121 to move from the scraping position to the avoidance position, and shutting off the water supply element connected to the water inlet channel 13, stopping the water supply to the water inlet channel 13. After the scraper 121 moves to the avoidance position, a communication channel is formed between the water storage section 16 and the drainage section 17, which were originally surrounded by the scraper 121 and the wall of the receiving cavity 11. The water storage section 16 is further connected to the water outlet channel 14 and the drain outlet 15 via the drainage section 17, thereby establishing a continuous drainage path from the water storage section 16 → drainage section 17 → water outlet channel 14 → drain outlet 15.
[0172] Under the influence of gravity, the sewage in the water storage section 16 flows to the drainage section 17 along the drainage channel between the bottom surface of the water storage section 16 and the scraper 121 and the bottom surface, and then enters the water outlet channel 14 through the opening at the bottom of the drainage section 17, and is finally discharged from the cleaning tray 10 / cleaning base station through the drain outlet 15. Since the bottom surface of the drainage section 17, the bottom surface of the water outlet channel 14 and the opening of the drain outlet 15 are set to gradually decrease in height along the X direction in the aforementioned structure, it is conducive to the smooth discharge of sewage and reduces the retention of residual liquid.
[0173] In S1030, the cleaning component 20 is controlled to leave the receiving cavity 11.
[0174] After the drainage operation is completed, the scraper 121 is in a clearance position and away from the main area of the receiving cavity 11. At this time, the cleaning device is driven to exit the cleaning base station, or the constraint between the cleaning component 20 and the cleaning tray 10 is released, allowing the cleaning component 20 to leave the receiving cavity 11 along a predetermined path. Since the sewage in the water storage section 16 has been basically drained at this time, and the scraper 121 is no longer in the movement path of the cleaning component 20, the cleaning component 20 will not be soaked in highly polluted sewage again during the departure process, nor will it be subject to additional friction or obstruction by the scraper 121, thereby ensuring that the cleaning component 20 returns to the standby position in a relatively clean state after completing self-cleaning.
[0175] In some embodiments, the drive conversion assembly 122 includes an actuator 1221, a paddle 1222, and a transmission rod 1223. The actuator 1221 is disposed on the cleaning component 20, for example, mounted within the end bracket of a roller brush or roller mop. The actuator 1221 can be a small motor, a geared motor, or other drive element capable of outputting rotational power. The paddle 1222 is coaxially connected to the scraping component 121 and is fixed to the rotation shaft 1211 of the scraping component 121, ensuring that the paddle 1222 and the scraping component 121 remain coaxial and rotate together in the first axial direction. One end of the transmission rod 1223 is drively connected to the output shaft of the actuator 1221, and the other end is located near the movement path of the paddle 1222, and can intermittently contact the paddle 1222 under the drive of the actuator 1221.
[0176] During the process of controlling the drive conversion assembly 122 to drive the scraper 121 to the scraping position, the actuator 1221 is first controlled to rotate in a preset direction. As the output shaft of the actuator 1221 rotates, one end of the transmission rod 1223 moves, rotates, or oscillates, thereby driving the output end of the transmission rod 1223 to move along a predetermined trajectory. Within one working cycle, the output end of the transmission rod 1223 enters the angle region where the paddle 1222 is located, contacts the side or abutment surface of the paddle 1222, and applies a thrust or torque to the paddle 1222 during continued rotation.
[0177] Under the force of the lever 1222, the lever 1222 rotates around the first axis, and drives the scraper 121, which is coaxially connected to it, to rotate around the first axis as well, so that the scraper 121 rotates from the original avoidance position to the scraping position. Preferably, a limiting structure or a reset elastic element can be provided on the scraper 121 or its rotating shaft 1211, so that after the scraper 121 rotates to the scraping position, it is held in the scraping position by the limiting surface abutting or the elastic element pre-tightening, so that the scraper 121 remains stably in the scraping position throughout the entire cleaning stage when the cleaning element 20 rolls along the receiving cavity 11. At this time, the scraping part 1212 of the scraper 121 contacts the outer peripheral surface of the cleaning element 20, and the water in the water storage part 16 scrapes and cleans the cleaning element 20.
[0178] When the cleaning stop condition is detected, the actuator 1221 is controlled to rotate in the reverse direction or stop working. After the actuator 1221 rotates in the reverse direction or stops, the output end of the transmission rod 1223 retracts from the movement area of the paddle 1222, disengages from the paddle 1222, and no longer applies thrust / torque to the paddle 1222. In this state, the scraper 121 is no longer driven by the transmission rod 1223 and can be moved from the scraping position to the avoidance position by the action of the reset elastic element, its own weight, or other reset mechanisms, so that the scraper 121 moves away from the main receiving area of the receiving cavity 11, leaving sufficient space for subsequent drainage and the cleaning component 20 to leave the receiving cavity 11.
[0179] Through the above specific implementation, the continuous rotational motion of the actuator 1221 is converted into an intermittent thrust on the paddle 1222 via the transmission rod 1223, thereby realizing the reliable switching of the scraping component 121 between the scraping position and the avoidance position; at the same time, the start-stop or reverse control of the actuator 1221 is combined with the cleaning stop condition, so that the scraping component 121 can maintain the scraping position during the cleaning phase and turn to the avoidance position during the drainage and exit phases. In conjunction with the aforementioned water storage / drainage control steps, a complete cleaning-drainage-exit control process is completed.
