Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device, a cleaning system, and a control method. Background Technology

[0002] Current floor cleaning methods mostly involve vacuuming, wet mopping, or floor scrubbing equipment to clean dry garbage and wet stains on the floor.

[0003] In existing technologies, when dealing with mixed dry and wet dirt, solid dirt such as hair, debris, and dust mixed with liquid dirt such as sewage tends to mix and adhere in the roller brush or suction channel, causing entanglement and blockage, which affects cleaning efficiency and cleaning effect.

[0004] Therefore, how to reduce the entanglement and clogging caused by mixed dry and wet dirt during the cleaning process, and ensure cleaning efficiency and effectiveness, is an urgent technical problem that needs to be solved. Summary of the Invention

[0005] This application provides cleaning equipment, a cleaning system, and a control method, which can reduce the problem of mixed dry and wet dirt clogging the suction pipe and affecting the cleaning effect and efficiency, while taking into account the cleaning effect of both dry and wet cleaning.

[0006] In a first aspect, embodiments of this application provide a cleaning device, which includes:

[0007] body;

[0008] A floor brush assembly is rotatably connected to the body and is capable of rotating on the surface to be cleaned, having at least a first cleaning posture and a second cleaning posture. The floor brush assembly includes a floor brush body and a first cleaning component and a second cleaning component disposed on the floor brush body. The first cleaning component and the second cleaning component are arranged side by side along the front-back direction of the floor brush assembly. The first cleaning component is used for dry cleaning of the surface to be cleaned, and the second cleaning component is used for wet cleaning of the surface to be cleaned.

[0009] The first air duct is provided with a first suction port, which is located on the main body of the floor brush and adjacent to the first cleaning component. The first suction port is used to suck the dirt generated by the first cleaning component during dry operation into the first air duct.

[0010] The second air duct is provided with a second suction port, which is located on the main body of the floor brush and adjacent to the second cleaning component. The second suction port is used to suck the dirt generated by the second cleaning component during wet operation into the second air duct. The first air duct and the second air duct are isolated from each other.

[0011] An auxiliary wheel is provided on the main body of the floor brush, and the auxiliary wheel supports the floor brush assembly to move on the surface to be cleaned;

[0012] Wherein, along the forward pushing direction of the floor brush assembly, when the floor brush assembly is in the first cleaning posture, the first cleaning component is located in front of the second cleaning component; when the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component.

[0013] The cleaning device provided in this application rotatably connects a floor brush assembly to the main body, allowing the assembly to rotate on the surface to be cleaned to have at least a first cleaning posture and a second cleaning posture. Users can flexibly switch the cleaning posture of the floor brush assembly according to the material, type of dirt, and degree of dirt on the surface. When the floor brush assembly is in the first cleaning posture, the first cleaning component is located in front of the second cleaning component. In this case, the first cleaning component performs dry cleaning on the surface to be cleaned first, effectively removing dry dirt such as hair, debris, and dust, preventing dry debris from clumping when it comes into contact with water during subsequent wet cleaning. When the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component. In this case, the second cleaning component performs wet cleaning on the surface to be cleaned first. This is particularly suitable for scenarios with heavy oil stains and liquid stains. By switching between the first and second cleaning postures, the same cleaning device can meet the needs of different cleaning scenarios, thereby improving the versatility and cleaning effect of the cleaning device.

[0014] By separately setting up a first air duct and a second air duct, and isolating the first air duct and the second air duct from each other, the dry dirt generated by dry cleaning operations and the wet dirt generated by wet cleaning operations can be transported and collected through their respective independent paths (the first air duct and the second air duct), so that the dry dirt and wet dirt can be separated at the starting end after entering the main body of the floor brush.

[0015] Therefore, moisture and liquid droplets can be confined within the second air duct and cannot enter the first air duct or the first suction component connected to the first air duct. This effectively reduces the possibility of liquid intrusion into the first suction component causing short circuits, corrosion, and other phenomena, thereby improving the service life of the first suction component and ensuring the stable, reliable, and safe operation of the cleaning equipment.

[0016] In this embodiment, by providing auxiliary wheels to the main body of the floor brush, the auxiliary wheels can support the floor brush assembly to move on the surface to be cleaned. The auxiliary wheels can improve the smoothness of the floor brush assembly switching between the first cleaning posture and the second cleaning posture. The auxiliary wheels, together with the first and second cleaning components, constitute a multi-point support system for the floor brush assembly, ensuring the stability of the floor brush assembly during the cleaning process and reducing the possibility that insufficient contact between the cleaning components and the surface to be cleaned due to tilting or bumping of the floor brush body could affect the consistency of cleaning results under different cleaning postures.

[0017] Furthermore, the auxiliary wheels can share some of the weight of the floor brush assembly, reducing the pressure between the first and second cleaning components and the surface to be cleaned. This helps to reduce the wear rate of the first and second cleaning components and extend their service life. In addition, it can reduce the thrust required for the user to operate the handle connected to the body to push the cleaning equipment, thus improving the ease of operation for the user.

[0018] In one possible implementation, the first cleaning element rotates about its own axis, the axis of the first cleaning element being parallel to the surface to be cleaned, and the rotation direction of the first cleaning element is configured to guide the dirt generated on the surface to be cleaned to the first suction port.

[0019] In this embodiment, the first cleaning component is capable of separating, picking up, and gathering dry dirt on the surface to be cleaned. By configuring the rotation direction of the first cleaning component to guide the dry dirt generated on the surface to be cleaned to the first suction port, the dry dirt generated on the surface to be cleaned can be guided in an orderly manner, thereby reducing the possibility of dry dirt adhering to areas outside the first air duct during the suction process. The area outside the first air duct can be the inner wall of the brush body or the gaps between components.

[0020] In one possible implementation, the system further includes a first suction assembly and a dust box. The first air duct has a first air outlet at the end away from the first suction port. The first air outlet is connected to the first suction assembly, and the dust box is located on the airflow path between the first suction port and the first suction assembly.

[0021] In this embodiment, since the first and second air ducts are isolated from each other, and the dust box is connected to the airflow path of the first air duct, the dust box can be used only to collect dry dirt from the first air duct. In other words, the dust box can be configured as a collection container specifically for dry dirt from dry cleaning operations. Therefore, wet dirt such as wastewater generated from wet cleaning operations is transported independently through the second air duct and cannot enter the dust box.

[0022] Therefore, the inside of the dustbin can always maintain a dry environment, preventing dry dirt (such as hair, debris, and dust) from coming into contact with moisture or liquid. On one hand, dry dirt won't clump, mold, or stick to the inner walls of the dustbin due to moisture absorption. When emptying the dustbin, the dirt can slide out smoothly without the need for scraping the inner walls, reducing the difficulty of cleaning and improving the thoroughness and convenience of emptying. On the other hand, the filter components inside the dustbin (such as HEPA filters and sponge filters) won't become damp, clogged, or breed bacteria due to contact with moisture. The filtration efficiency remains stable over a long period, reducing the possibility of decreased suction power and frequent replacements due to moisture absorption, thus extending the lifespan of the filter components and reducing user maintenance costs.

[0023] In one possible implementation, both the dustbin and the first suction assembly are disposed on the floor brush body, with the first suction assembly disposed adjacent to the dustbin; or...

[0024] The dust box is disposed on the main body of the floor brush, and the first suction component is disposed on the body.

[0025] In this embodiment, the first air duct, dust box, and first suction component are integrated inside the main body of the floor brush to form a compact dry cleaning module. This helps to reduce the size and weight of the floor brush component, facilitates the lightweight design of the cleaning equipment, and improves the accessibility and operational flexibility of the cleaning equipment in low spaces (such as under furniture, under beds, etc.).

[0026] By integrating the first air duct, dust box, and first suction component inside the main body of the floor brush, the airflow path between the first suction port, the first air duct, the dust box, and the first suction component is significantly shortened. Specifically, the length and number of bends in the first air duct can be reduced, effectively minimizing negative pressure loss during transmission and allowing the suction force generated by the first suction component to be transmitted to the first suction port more efficiently. Under the same input power, the first suction component can have stronger suction performance; alternatively, under the same suction performance requirements, a lower power consumption suction component can be used, helping to reduce overall energy consumption. Furthermore, the proximity of the first suction component to the dust box allows the clean airflow after gas-solid separation in the dust box to directly enter the first suction component after exiting the dust box, eliminating the need for long-distance pipeline transport. This reduces secondary leakage or suction loss caused by poor pipeline sealing during transport, further improving pneumatic efficiency.

[0027] Furthermore, the first suction component is located on the main body of the floor brush, which significantly lowers the overall center of gravity and shifts it forward to the floor brush assembly. On one hand, lowering the center of gravity improves the stability of the cleaning equipment during operation and posture changes, reducing the likelihood of the floor brush assembly tilting or tipping over when the user pushes the machine. This is especially beneficial when the floor brush assembly rotates to change cleaning postures, effectively reducing the possibility of the cleaning equipment tipping over and improving stability and safety. On the other hand, it reduces the weight of the machine. The inertial torque and steering torque required for the user to push the machine are correspondingly reduced, effectively lowering the pushing force and operating effort required to push the machine, making cleaning operations more effortless and convenient. This is particularly beneficial for large homes or long-term continuous cleaning scenarios, effectively alleviating wrist and arm fatigue and improving user comfort.

[0028] In one possible implementation, the second cleaning element rotates about its own axis, and the axis of the second cleaning element is parallel to the surface to be cleaned;

[0029] When the floor brush assembly is in the first cleaning posture, the rotation direction of the second cleaning component is opposite to the rotation direction of the auxiliary wheel;

[0030] When the floor brush assembly is in the second cleaning posture, the rotation direction of the second cleaning component is the same as the rotation direction of the auxiliary wheel.

[0031] In this embodiment, the second cleaning component can form continuous and uniform contact with the surface to be cleaned through its outer peripheral surface during operation, so as to effectively perform wet cleaning operations.

[0032] In this configuration, when the floor brush assembly is in the first cleaning posture, the first cleaning component is located in front of the second cleaning component, which is a rear-mounted cleaning component. The rotation direction of the second cleaning component is opposite to that of the auxiliary wheel. At this time, the tangential velocity direction of the contact area between the second cleaning component and the surface to be cleaned points towards the rear of the floor brush assembly. This allows the wastewater, wet mud, and other wet dirt generated during the wet operation of the second cleaning component to be guided backward to the second suction port located behind it. This reduces the splashing of wet dirt towards the area where the first cleaning component is located, thus effectively isolating the dry cleaning area from the wet cleaning area and reducing the possibility of the first cleaning component and the first air duct being contaminated by moisture.

[0033] When the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component. As a front-mounted cleaning component, the second cleaning component rotates in the same direction as the auxiliary wheel. At this time, the tangential velocity of the part of the second cleaning component that contacts the surface to be cleaned points towards the rear of the floor brush assembly, causing the wet dirt picked up by the second cleaning component to move orderly and be smoothly sucked into the rearward suction port.

[0034] Therefore, by changing the rotation direction of the second cleaning component, the rotation direction of the second cleaning component can be configured to guide wet dirt to the corresponding direction of the second suction port when the floor brush assembly is in the first cleaning posture or the second cleaning posture. This allows the second cleaning component to efficiently pick up and directionally transport wet dirt in both the first and second cleaning postures, thereby reducing the possibility of secondary pollution or cleaning dead spots caused by wet dirt being pushed in the wrong direction due to posture switching. This is beneficial to improving the wet cleaning effect and reliability of the cleaning equipment in various cleaning modes.

[0035] In one possible implementation, the second suction port is provided with a first opening and a second opening. Along the front-rear direction of the floor brush assembly, the first opening and the second opening are located on both sides of the second cleaning component, and the second opening is closer to the auxiliary wheel.

[0036] When the floor brush assembly is in the first cleaning posture, the first opening is in the open state and the second opening is in the closed state.

[0037] When the floor brush assembly is in the second cleaning posture, the second opening is in the open state and the first opening is in the closed state.

[0038] In this embodiment, the second suction port is provided with suction channels on both sides of the second cleaning component, so that when the floor brush assembly is in the first cleaning posture or the second cleaning posture, an effective suction port (first opening or second opening) can be provided on the side corresponding to the second cleaning component.

[0039] When the floor brush assembly is in the first cleaning posture, the first cleaning component is located in front of the second cleaning component. At this time, the second cleaning component acts as a rear cleaning component, and the wet dirt generated by the wet operation of the second cleaning component moves to the rear. Along the forward pushing direction of the floor brush assembly, the first opening on the rear side can be in an open state, and the second opening on the front side can be in a closed state, so that the second suction port can only suck up dirt through the first opening on the rear side of the second cleaning component. This reduces the possibility of suction dispersion and negative pressure loss caused by the simultaneous opening of the first and second openings, and ensures that the suction negative pressure at the first opening on the rear side is concentrated and sufficient.

[0040] When the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component. At this time, the second cleaning component acts as the front cleaning component, and the wet dirt generated by the wet operation of the second cleaning component moves to the rear. Along the forward pushing direction of the cleaning device, the second opening located at the rear is in the open state, and the first opening located at the front is in the closed state, which allows the second suction port to suck up dirt only through the second opening located at the rear of the second cleaning component.

[0041] By selectively switching the opening and closing states of the first and second openings according to the cleaning posture, the second suction port can always only open the opening located on the rear side of the second cleaning component (i.e., the downstream side in the direction of dirt movement) when the floor brush assembly is in the first or second cleaning posture. This ensures that wet dirt can enter the corresponding opening directly through a short path after being rolled up, thereby improving the cleaning effect. At the same time, it reduces the possibility of suction dispersion and negative pressure loss caused by the simultaneous opening of the first and second openings, which is conducive to improving the effective power utilization rate of the suction assembly.

[0042] In one possible implementation, a movable switch is provided in the second air duct. When the floor brush assembly is in the first cleaning posture, the movable switch closes the second opening; when the floor brush assembly is in the second cleaning posture, the movable switch closes the first opening.

[0043] In this embodiment, the active switch allows for selective closing and opening of either the first or second opening, ensuring that the second suction port effectively draws out dirt through a single opening located behind the second cleaning component, regardless of the cleaning posture of the floor brush assembly.

[0044] In one possible implementation, the system further includes a second suction assembly and a wastewater tank. The second air duct has a second air outlet at one end away from the second suction port. The second air outlet is connected to the second suction assembly, and the wastewater tank is located on the airflow path between the second suction port and the second suction assembly.

[0045] In this embodiment, the negative pressure generated during the operation of the second suction component is transmitted to the second air duct and the second suction port via the second air outlet. This allows wet wastewater, wet mud, and other wet contaminants generated during the wet operation of the second cleaning component to be drawn into the second air duct through the second suction port. The wet contaminants are intercepted and collected in the wastewater tank during the airflow process. The separated airflow is discharged from the second air duct via the second air outlet and enters the second suction component, ultimately being discharged into the external environment.

[0046] The wet dirt is drawn into the sewage tank through the second suction port and then undergoes gas-liquid separation. Moisture, droplets, and wet dust are trapped inside the sewage tank. The separated airflow is relatively dry and clean. Therefore, the gas entering the second suction component carries a lower content of droplets and particulate matter, which can effectively reduce the entry of moisture and dirt into the second suction component, thus preventing problems such as moisture absorption, short circuits, corrosion, and impeller wear. This helps to extend the service life and operational reliability of the second suction component.

[0047] Furthermore, the wastewater tank is located along the second air duct path, centralizing the collection of wet dirt. Users only need to clean the wastewater tank to empty the wet dirt, eliminating the need for frequent cleaning of the second air duct. In addition, because the first and second air ducts are isolated from each other, the dust box for dry cleaning and the wastewater tank for wet cleaning are independently set up. Dry and wet dirt are collected separately from the beginning. Users can empty the dust box and wastewater tank separately to clean dry and wet dirt respectively, thus reducing the cumbersome solid-liquid separation required for mixed dry and wet dirt, improving maintenance convenience and user experience.

[0048] In one possible implementation, both the wastewater tank and the second suction assembly are disposed on the machine body, with the second suction assembly disposed adjacent to the wastewater tank.

[0049] In this embodiment, the wastewater tank and the second suction component are integrated inside the machine body, which can form a compact wet cleaning module, which helps to reduce the overall size of the machine and improve the mobility and storage convenience of the cleaning equipment in small spaces.

[0050] Furthermore, the second suction component is located near the sewage tank, which allows the airflow after gas-liquid separation in the sewage tank to enter the second suction component immediately after being discharged from the sewage tank, without the need for long-distance pipeline transportation. This reduces the secondary leakage or suction loss of the clean airflow during transportation due to poor pipeline sealing.

[0051] In addition, by integrating the wastewater tank and the second suction component inside the machine body, the weight of the floor brush assembly can be reduced, thereby reducing the motion resistance of the floor brush assembly when rotating relative to the machine body and changing its posture, and improving the ease and smoothness of the user's operation of the floor brush assembly.

[0052] In one possible implementation, the auxiliary wheel is a booster wheel, and there are two booster wheels. The two booster wheels are respectively arranged on both sides of the width direction of the floor brush assembly, and the floor brush assembly achieves steering by the differential rotation of the two booster wheels.

[0053] In this embodiment, the two assist wheels can support the floor brush assembly as it moves on the surface to be cleaned, and can also have an active driving assist function.

[0054] On one hand, the power-assisted wheels provide driving force for pushing or pulling the floor brush assembly forward or backward. When the user pushes the machine, only a small guiding force is required, and the power-assisted wheels can drive the floor brush assembly to move automatically in the direction of the user's movement. Therefore, it can reduce the pushing force required for the user to push the cleaning device. It is especially suitable for large homes or long-term continuous cleaning scenarios, which can effectively relieve wrist and arm fatigue and improve the ease of operation and user comfort.

[0055] On the other hand, steering can be achieved through the differential rotation of the two assist wheels. When steering is required, the two assist wheels can be controlled to rotate at different speeds or in different directions. The speed difference between the two assist wheels generates a steering torque, allowing the floor brush assembly to complete the steering action on the surface to be cleaned, without relying on the body pushing or pulling or the lateral sliding of the floor brush assembly.

[0056] By using the differential rotation of two assist wheels for reversing direction, the turning radius of the floor brush assembly can be reduced, and even reversing on the spot can be achieved. This significantly improves the flexibility and maneuverability of the cleaning equipment in confined spaces (such as between table and chair legs, furniture corners, and narrow aisles), reduces blind spots, and lowers the likelihood of the floor brush assembly colliding with furniture or corners when the cleaning equipment turns, thus reducing the risk of damage to the cleaning equipment or furniture. Furthermore, the differential steering method eliminates the need for independent steering wheels or mechanisms, simplifying the structure of the floor brush assembly and reducing structural complexity and overall machine cost.

[0057] In one possible implementation, when the floor brush assembly is in the first cleaning posture, the floor brush assembly is configured with a switchable first cleaning mode and a second cleaning mode.

[0058] In the first cleaning mode, the first cleaning component rotates while the second cleaning component remains stationary;

[0059] In the second cleaning mode, both the first cleaning component and the second cleaning component rotate.

[0060] In this application embodiment, the cleaning equipment may be applied to, but is not limited to, the following scenarios.

[0061] When the local brush assembly is in the first cleaning posture, the first cleaning component for dry cleaning is located on the front side, and the second cleaning component for wet cleaning is located on the rear side.

[0062] When only dry cleaning of the surface needs to be performed (such as hair, debris, and dust) and wet cleaning is not required, the user can select the first cleaning mode. In the first cleaning mode, only the first cleaning component rotates to perform dry cleaning, and the first suction component works to suck the dry dirt into the dust box through the first suction port, while the second cleaning component remains stationary. This reduces unnecessary contact and friction between the second cleaning component and the surface to be cleaned when wet cleaning is not required, thereby reducing the wear rate of the second cleaning component, extending its service life, and reducing the energy consumption and operating noise of the second cleaning component during unused periods, which helps to improve the overall energy efficiency of the machine.

[0063] When deep cleaning or cleaning of mixed wet and dry dirt is required, users can select the second cleaning mode. In the second cleaning mode, both the first and second cleaning components rotate. The first cleaning component performs dry cleaning on the surface, effectively picking up and removing dry dirt such as hair, debris, and dust. The second cleaning component then performs wet cleaning on the surface after dry cleaning. The rotating second cleaning component, in conjunction with liquid supply, performs a mopping operation to remove water stains, fine dust, and stubborn stains such as residual oil. This setup allows for the orderly and coordinated operation of dry and wet cleaning within the same cleaning cycle. Dry cleaning first prevents dry dirt from clumping when it comes into contact with water, while wet cleaning afterwards ensures deep cleaning. The two work together without interference, saving cleaning time and reducing energy consumption, as well as user operation time and fatigue. This improves cleaning efficiency while ensuring cleaning effectiveness. It is especially suitable for complex cleaning scenarios such as kitchens and restaurants where mixed wet and dry dirt coexists.

[0064] Furthermore, when the local brush assembly is in the second cleaning posture, the second cleaning component for wet cleaning is located on the front side, and the first cleaning component for dry cleaning is located on the rear side.

[0065] When only wet cleaning of wet dirt (such as water stains) is required on the surface to be cleaned, and dry cleaning is not necessary, the brush assembly can be controlled to adjust to the second cleaning posture. In this mode, only the second cleaning component rotates to perform wet cleaning, and the second suction component works to suck the wet dirt into the wastewater tank through the second suction port, while the first cleaning component remains stationary. This reduces unnecessary contact and friction between the first cleaning component and the surface to be cleaned when wet cleaning is not required, thereby reducing the wear rate of the first cleaning component, extending its service life, and reducing energy consumption and operating noise during unused periods of idling, which helps improve the overall energy efficiency of the machine.

[0066] In one possible implementation, the first cleaning component is vertically connected to the floor brush body to have a lowered position and a raised position;

[0067] When the first cleaning component is in the lowered position, the first cleaning component is in contact with the surface to be cleaned; when the first cleaning component is in the raised position, the first cleaning component is not in contact with the surface to be cleaned.

[0068] Wherein, when the floor brush assembly is in the first cleaning posture and the floor brush assembly is running in the forward direction, the first cleaning component is in the descending position;

[0069] When the floor brush assembly is in the second cleaning mode and the floor brush assembly is running in the backward direction, and when the floor brush assembly is in the second cleaning posture, the first cleaning component is in the raised position.

[0070] In this embodiment, the working state of the first cleaning component can be adjusted according to the cleaning posture and running direction of the floor brush assembly to effectively ensure the isolation and switching reliability between dry cleaning and wet cleaning.

[0071] When the floor brush assembly is in the second cleaning mode and moving backward, the second cleaning component performs wet cleaning, leaving damp mopping marks and liquid on the surface to be cleaned. If the first cleaning component is still in the descending position, as the floor brush assembly is pulled backward, the first cleaning component directly contacts the surface to be cleaned after wet mopping. The bristles on the first cleaning component quickly absorb the residual moisture, liquid, and wet dirt from the floor. On one hand, after absorbing water and becoming damp, the bristles of the first cleaning component become soft, clump, or stick together. When switching back to the first cleaning posture to perform dry cleaning, the damp bristles are unable to effectively pick up hair, debris, and other dry dirt. In fact, due to excessive humidity, the dry dirt may even adhere to the bristles and be difficult to remove, affecting the dry cleaning effect. On the other hand, during the rotation of the damp first cleaning component, the water and wet dirt it carries will enter the first air duct through the first suction port with the airflow, causing an adhesive layer to form on the inner wall of the first air duct, which is difficult to clean. Furthermore, moisture can also penetrate the dust box, causing the dry dirt already collected inside to become damp and clump together. Moisture can even enter the first suction component along the first air duct, causing malfunctions such as moisture absorption and short circuits in the first suction component.

[0072] Therefore, by raising the first cleaning component to a point where it is no longer in contact with the surface to be cleaned when the first cleaning component is in the second cleaning mode and is pulled back, this application can reduce the possibility of the first cleaning component coming into contact with the surface to be cleaned after wet mopping. This effectively avoids the problem of the first cleaning component getting damp and the first air duct being contaminated by moisture, so that the first cleaning component always remains dry and clean when switching back to dry cleaning, thus ensuring the continuous stability of the dry cleaning effect. It can also reduce the possibility of moisture intruding into the first air duct and the first suction component, causing the cleaning equipment to malfunction.

[0073] Secondly, embodiments of this application provide a cleaning system, including:

[0074] Cleaning equipment as described in any of the above embodiments;

[0075] The cleaning equipment can be placed on the base station.

[0076] In one possible implementation, the base station includes a first storage container and a second storage container that are not connected to each other;

[0077] The first storage container is used to communicate with the dust box of the cleaning equipment, and the second storage container is used to communicate with the wastewater tank of the cleaning equipment.

[0078] In this embodiment of the application, when the base station receives the dirt collected by the cleaning equipment, it can connect to the dry dust collection box and the wet wastewater collection tank of the cleaning equipment respectively without connecting the first and second collection containers, so as to achieve the separation and partitioned collection of dry dirt and wet dirt on the base station side.

[0079] The first storage container is used only to receive and store dry dirt from the dust box, while the second storage container is used only to receive and store wet dirt from the wastewater tank. The first and second storage containers are not connected to each other, ensuring that dry and wet dirt remain separated throughout the entire process from discharge by the cleaning equipment to collection at the base station. This effectively reduces the possibility of clumping, mold, odors, and bacterial growth caused by mixed dry and wet dirt, ensuring the cleanliness and hygiene of the cleaning equipment and the internal environment of the base station.

[0080] In one possible implementation, the second storage container is provided with a filter element that divides the internal space of the second storage container into a first cavity and a second cavity that are interconnected.

[0081] The filter element is used to block and retain solid waste generated by wet cleaning in the first cavity, and to allow wastewater to flow through the filter element into the second cavity.

[0082] In this embodiment, the wet dirt discharged from the wastewater tank of the cleaning equipment enters the second storage container and can first enter the first cavity. When the wet dirt passes through the filter element, solid dirt (such as hair, food residue, mud, etc.) in the wet dirt can be intercepted by the filter element and retained in the first cavity, while liquid dirt can pass through the filter element and flow into the second cavity, realizing solid-liquid separation and partitioned storage of wet dirt on the base station side.

[0083] Thirdly, embodiments of this application provide a control method for a cleaning device, the cleaning device including a body, a floor brush assembly, a first air duct, a second air duct, and auxiliary wheels;

[0084] The floor brush assembly is rotatably connected to the body and can rotate on the surface to be cleaned, so as to have at least a first cleaning posture and a second cleaning posture.

[0085] The floor brush assembly includes a floor brush body and a first cleaning component and a second cleaning component disposed on the floor brush body. The first cleaning component and the second cleaning component are arranged side by side along the front-back direction of the floor brush assembly. The first cleaning component is used for dry cleaning of the surface to be cleaned, and the second cleaning component is used for wet cleaning of the surface to be cleaned. When the floor brush assembly is in the first cleaning posture along the forward pushing direction of the floor brush assembly, the first cleaning component is located in front of the second cleaning component; when the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component.

[0086] The first air duct is used to suck up dirt generated during the dry operation of the first cleaning component; the second air duct is used to suck up dirt generated during the wet operation of the second cleaning component, and the first air duct and the second air duct are isolated from each other; the auxiliary wheel is disposed on the main body of the floor brush, and the auxiliary wheel supports the floor brush assembly to move on the surface to be cleaned;

[0087] The method includes:

[0088] In response to a rotation request for the floor brush assembly, the floor brush assembly is controlled to rotate relative to the body to present a first target cleaning posture corresponding to the rotation request; wherein, the first target cleaning posture includes a first cleaning posture or a second cleaning posture.

[0089] In this embodiment, dry and wet dirt are transported and collected separately in their respective cleaning areas and isolated independent air ducts. This ensures that dry and wet dirt are separated and processed from the source of suction, effectively reducing the possibility of them mixing and accumulating in the floor brush assembly and clogging the air ducts. This guarantees the long-term unobstructed flow of the suction channel, improves the reliability of the cleaning equipment, and increases cleaning efficiency. Furthermore, the matching relationship between the corresponding cleaning component and the corresponding air duct is automatically established after the floor brush assembly's posture is switched, requiring no additional settings or adjustments from the user, making operation simple and convenient.

[0090] In one possible implementation, the rotation request is generated by the cleaning device in response to a user's preset rotation operation;

[0091] The preset rotation operation includes triggering a preset button on the cleaning device and / or applying an adjustment operation to the floor brush assembly to rotate around the body.

[0092] In this embodiment, users can switch the attitude of the floor brush component through at least one of two methods: preset button triggering (such as pressing / rotating the button, sending commands through the application, voice control, etc.) and manual force adjustment, so as to meet the diverse needs of different application scenarios and user habits.

[0093] In one possible implementation, prior to controlling the floor brush assembly to rotate relative to the body to present the target cleaning posture corresponding to the rotation request, the method further includes:

[0094] Obtain the cleaning scene and the current cleaning posture of the floor brush component; wherein, the cleaning scene includes:

[0095] Based on the cleaning scenario, a second target cleaning posture is determined; wherein, the second target cleaning posture includes either the first cleaning posture or the second cleaning posture.

[0096] The rotation request is generated based on the current cleaning posture and the second target cleaning posture.

[0097] In this embodiment, the cleaning posture switching of the floor brush component can be based on the automatic identification of the cleaning scene and the comprehensive judgment of the current cleaning posture to generate a rotation request autonomously, so as to realize intelligent decision-making and automatic switching of the cleaning posture.

[0098] In one possible implementation, when the floor brush assembly is in the first cleaning posture, the rotation direction of the second cleaning component is controlled to be opposite to the rotation direction of the auxiliary wheel;

[0099] When the floor brush assembly is in the second cleaning posture, the rotation direction of the second cleaning component is controlled to be the same as the rotation direction of the auxiliary wheel.

[0100] In this embodiment, the control unit automatically configures the rotation direction of the second cleaning component according to the current cleaning posture of the floor brush assembly, so that the tangential velocity direction of the part in contact with the surface to be cleaned always points in the direction of the second suction port. Thus, regardless of whether the floor brush assembly is in the first or second cleaning posture, the wet dirt generated by wet cleaning can obtain an orderly movement trend toward the second suction port, ensuring efficient suction of wet dirt, reducing secondary pollution or cleaning dead corners caused by wet dirt being pushed in the wrong direction due to the switching of cleaning posture, and improving the wet cleaning effect and reliability of the cleaning equipment in multiple cleaning modes.

[0123] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0124] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0125] The cleaning equipment described in this application can be widely used in home environments such as kitchens, living rooms, bedrooms, and bathrooms to remove dust, hair, debris, water stains, and oil residue from different surfaces such as tiles, wooden floors, and cement floors.

[0126] The cleaning equipment can be, but is not limited to, a floor scrubber. This application uses a floor scrubber as an example. A floor scrubber is a device used to clean floors, carpets, and other surfaces, and generally includes multiple parts such as a floor brush assembly, a main fan, a clean water tank, and a wastewater tank.

[0127] Current floor cleaning solutions mostly employ vacuuming, wet mopping, or floor washing methods. The working principle of cleaning equipment is usually that the cleaning component located at the front or bottom of the brush assembly contacts the surface to be cleaned, and then the suction channel sucks the dirt generated during the cleaning process into the machine body.

[0128] However, when a wet roller brush cleans a surface, solid dirt such as hair, dust, and debris mixes with liquid dirt such as water and sludge, and enters the roller brush area or suction channel along with the fluid. The solid-liquid mixture formed by the solid and liquid dirt easily adheres to the inner wall of the suction channel, causing accumulation and blockage.

[0129] Clogged suction channels can obstruct airflow, leading to a rapid decrease in the machine's effective suction power and impacting cleaning performance and efficiency. Furthermore, clumps of hair continuously entangle the brush rollers, affecting their cleanliness and causing the cleaning process to worsen. The continuous entanglement of hair also increases the load on the brush rollers, potentially causing motor overload, overheating, wear, and even malfunctions, thus affecting the stability and reliability of the cleaning equipment.

[0130] To address the aforementioned technical problems, this application provides a cleaning device, a cleaning system, and a control method. The cleaning device includes a main body, a floor brush assembly, a first air duct, a second air duct, and auxiliary wheels. By setting the first and second air ducts as independent channels isolated from each other, dry dirt generated during dry cleaning and wet dirt generated during wet cleaning can be transported and collected through their respective independent paths, achieving source separation of mixed dry and wet dirt upon entering the floor brush body. Dry dirt will not come into contact with water or liquid, thus fundamentally avoiding the problems of clumping, expansion, and air duct blockage caused by mixing dry and wet dirt. This ensures the long-term unobstructed flow of the suction channel and reduces the possibility of suction power attenuation affecting cleaning effect and efficiency.

[0131] The cleaning equipment, cleaning system, and control method provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0132] See Figure 1 As shown, the cleaning device 100 of this application embodiment includes a body 110, a floor brush assembly 120, a first air duct 130, a second air duct 140, and an auxiliary wheel 150.

[0133] The floor brush assembly 120 is rotatably connected to the body 110. The floor brush assembly 120 is capable of rotating on the surface to be cleaned, having at least a first cleaning posture and a second cleaning posture. The floor brush assembly 120 includes a floor brush body 121, and a first cleaning member 122 and a second cleaning member 123 disposed on the floor brush body 121. The first cleaning member 122 and the second cleaning member 123 are arranged side-by-side along the front-back direction (e.g., the X direction) of the floor brush assembly 120. The first cleaning member 122 is used for dry cleaning of the surface to be cleaned. The second cleaning member 123 is used for wet cleaning of the surface to be cleaned.

[0134] The first air duct 130 is provided with a first suction port 130a. The first suction port 130a is located on the floor brush body 121 and adjacent to the first cleaning component 122. The first suction port 130a is used to suck the dirt generated by the first cleaning component 122 during dry operation into the first air duct 130.

[0135] The second air duct 140 is provided with a second suction port 140a. The second suction port 140a is located on the floor brush body 121 and adjacent to the second cleaning component 123. The second suction port 140a is used to suck the dirt generated by the second cleaning component 123 during wet operation into the second air duct 140. The first air duct 130 and the second air duct 140 are isolated from each other.

[0136] The auxiliary wheel 150 is mounted on the brush body 121. The auxiliary wheel 150 supports the brush assembly 120 as it moves on the surface to be cleaned.

[0137] In the first cleaning posture, when the floor brush assembly 120 is in the forward pushing direction, the first cleaning component 122 is located in front of the second cleaning component 123. When the floor brush assembly 120 is in the second cleaning posture, the second cleaning component 123 is located in front of the first cleaning component 122.

[0138] In this embodiment, by rotatably connecting the floor brush assembly 120 to the body 110, and enabling the floor brush assembly 120 to rotate on the surface to be cleaned to have at least a first cleaning posture and a second cleaning posture, the user can flexibly switch the cleaning posture of the floor brush assembly 120 according to the application scenario such as the material of the surface to be cleaned, the type of dirt, and the degree of dirt. When the floor brush assembly 120 is in the first cleaning posture, the first cleaning component 122 is located in front of the second cleaning component 123. At this time, the first cleaning component 122 performs dry cleaning on the surface to be cleaned first, so as to effectively remove dry dirt such as hair, debris, and dust, and prevent dry dirt from clumping when it comes into contact with water during subsequent wet cleaning. When the floor brush assembly 120 is in the second cleaning posture, the second cleaning component 123 is located in front of the first cleaning component 122. At this time, the second cleaning component 123 performs wet cleaning on the surface to be cleaned first. This is especially applicable to scenarios with heavy oil stains and liquid stains. By switching between the first cleaning posture and the second cleaning posture, the same cleaning device 100 can meet the needs of different cleaning scenarios, thereby improving the versatility and cleaning effect of the cleaning device 100.

[0139] By providing a first air duct 130 and a second air duct 140 respectively, and isolating the first air duct 130 and the second air duct 140 from each other, the dry dirt generated by dry cleaning operations and the wet dirt generated by wet cleaning operations can be transported and collected through their respective independent paths (first air duct 130 and second air duct 140), so that the dry dirt and wet dirt can be separated at the starting end after entering the floor brush body 121.

[0140] Specifically, dry dirt cannot come into contact with water or liquid, thus avoiding the problems of clumping, expansion, and air duct blockage caused by mixing dry and wet materials. This ensures the long-term unobstructed flow of the suction channel, reduces the problem of suction power attenuation affecting cleaning effect and efficiency, and reduces the frequency and difficulty of manual cleaning of components such as suction channels and filter components.

[0141] It should be noted that the first air duct 130 and the second air duct 140 are isolated from each other, meaning that the suction path formed by the first air duct 130 and the suction path formed by the second air duct 140 are not connected or intersect. In other words, the suction paths for dry dirt generated by the cleaning operation of the first cleaning component 122 and wet dirt generated by the cleaning operation of the second cleaning component 123 are completely independent. Specifically, the first air duct 130 and the second air duct 140 are not connected at their starting points, do not intersect in their respective extension paths, and are not connected at their ends.

[0142] Therefore, moisture and liquid droplets can be confined within the second air duct 140 and cannot enter the first air duct 130 or the first suction assembly 180 connected to the first air duct 130. This effectively reduces the possibility of liquid intrusion into the first suction assembly 180, which could lead to short circuits, corrosion, or other problems. As a result, the service life of the first suction assembly 180 can be improved, and the cleaning equipment 100 can be ensured to operate stably, reliably, and safely.

[0143] In this embodiment, by providing an auxiliary wheel 150 to the brush body 121, the auxiliary wheel 150 can support the brush assembly 120 to move on the surface to be cleaned. The auxiliary wheel 150 can improve the smoothness of the brush assembly 120 switching between the first cleaning posture and the second cleaning posture. The auxiliary wheel 150, together with the first cleaning component 122 and the second cleaning component 123, constitutes a multi-point support system for the brush assembly 120, ensuring the stability of the brush assembly 120 during the cleaning process and reducing the possibility that insufficient contact between the cleaning component and the surface to be cleaned due to tilting or bumping of the brush body 121 could affect the consistency of cleaning results under different cleaning postures.

[0144] Furthermore, the auxiliary wheel 150 can share part of the weight of the floor brush assembly 120, reduce the pressure between the first cleaning component 122 and the second cleaning component 123 and the surface to be cleaned, help reduce the wear rate of the first cleaning component 122 and the second cleaning component 123, and extend their service life. In addition, it can reduce the thrust required for the user to push the cleaning device 100 by operating the handle connected to the body 110, and improve the ease of operation for the user.

[0145] In some examples, the first cleaning component 122 and the second cleaning component 123 are two side-by-side cleaning execution components used for dry cleaning and wet cleaning, respectively, for zoned treatment of different types of stains, and their order is interchanged after a posture switch.

[0146] For example, the floor brush assembly 120 can rotate 180° relative to the body 110. Rotating the floor brush assembly 120 by 180° allows the first cleaning element 122 and the second cleaning element 123 to be interchanged in the front-rear direction X of the floor brush assembly 120.

[0147] In some examples, the first cleaning component 122 may be, but is not limited to, a roller brush, a bristle brush, a sponge strip, or an electrostatic adsorption strip.

[0148] In some examples, the second cleaning component 123 may be, but is not limited to, a wet mop, a squeegee, an absorbent cotton, etc.

[0149] In some examples, the first cleaning element 122 and the second cleaning element 123 may have similar axial lengths and be arranged side by side according to the effective width of the brush body 121.

[0150] In some examples, the mounting positions of the first cleaning component 122 and the second cleaning component 123 on the brush body 121 can be secured by clips, bushings, or replaceable brackets.

[0151] The first air duct 130, in conjunction with the first cleaning component 122, is an independent airflow channel for conveying dirty airflow during dry cleaning operations. The first air duct 130 can draw in dry dirt generated by the first cleaning component 122 during cleaning.

[0152] The second air duct 140, in conjunction with the second cleaning component 123, is an independent airflow channel for conveying dirty airflow during wet cleaning operations. The second air duct 140 can draw in wet dirt such as wastewater and atomized liquid generated during wet cleaning by the second cleaning component 123.

[0153] In some examples, the first air duct 130 can be a straight, bent, or segmented duct.

[0154] In some examples, the second duct 140 can be a straight, bent, or segmented duct.

[0155] In some examples, along the front-rear direction X of the floor brush body 121, the auxiliary wheel 150 can be located between the first cleaning component 122 and the second cleaning component 123 to balance the weight of the floor brush assembly 120 on both sides along the front-rear direction X, so that the floor brush assembly 120 can be evenly stressed during the forward and backward movement of the cleaning device 100, and the user can operate it with a light touch.

[0156] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the first cleaning component 122 rotates about its own axis. The axis of the first cleaning component 122 is parallel to the surface to be cleaned. The rotation direction of the first cleaning component 122 is configured to guide the dirt generated on the surface to be cleaned to the first suction port 130a.

[0157] In this embodiment, the first cleaning component 122 is capable of separating, picking up, and gathering dry dirt on the surface to be cleaned. By configuring the rotation direction of the first cleaning component 122 to guide the dry dirt generated on the surface to be cleaned to the first suction port 130a, the dry dirt generated on the surface to be cleaned can be guided in an orderly manner, thereby reducing the possibility of dry dirt adhering to areas outside the first air duct 130 during the suction process. The area outside the first air duct 130 can be the inner wall of the brush body 121 or the gaps between components.

[0158] Specifically, the airflow direction generated by the first cleaning component 122 during rotation and the direction of dry dirt ejection are both directed towards the first suction port 130a. In the initial stage after the dry dirt is rolled away from the surface to be cleaned by the first cleaning component 122, it receives a force moving towards the first suction port 130a. This allows the dry dirt to initially concentrate and enter the first air duct 130, thereby reducing the possibility of the dry dirt scattering disorderly after being rolled away from the surface, which could affect the cleaning effect.

[0159] The first cleaning component 122 can rotate continuously or intermittently around its own axis. Since the axis of the first cleaning component 122 is parallel to the surface to be cleaned, the outer peripheral surface of the first cleaning component 122 can form a uniform contact with the surface to be cleaned.

[0160] In some feasible ways, along the forward pushing direction of the floor brush assembly 120, the first suction port 130a may be located on the front side of the first cleaning member 122 or on the rear side of the first cleaning member 122, which is not limited in the embodiments of this application.

[0161] In some examples, along the forward pushing direction of the floor brush assembly 120, when the first suction port 130a is located in front of the first cleaning member 122, the rotation direction of the first cleaning member 122 is opposite to the rotation direction of the auxiliary wheel 150 when it moves forward.

[0162] During rotation, the tangential velocity of the contact area between the first cleaning component 122 and the surface to be cleaned points towards the front of the floor brush assembly 120. This allows the dry dirt picked up by the first cleaning component 122 to be propelled towards the first suction port 130a under the influence of centrifugal force and airflow. Under the combined effect of inertial force and negative pressure suction, the dirt smoothly enters the first suction port 130a. Therefore, the possibility of dry dirt escaping away from the first suction port 130a is effectively reduced, ensuring that the dry dirt always moves in an orderly manner towards the first suction port 130a. This improves the suction efficiency of dry cleaning, reduces the accumulation or leakage of dry dirt at the front end of the floor brush body 121, and enhances the cleaning effect.

[0163] In other examples, along the forward pushing direction of the floor brush assembly 120, when the first suction port 130a is located behind the first cleaning member 122, the rotation direction of the first cleaning member 122 is the same as the rotation direction of the auxiliary wheel 150 when it moves forward.

[0164] During rotation, the tangential velocity direction of the contact area between the first cleaning component 122 and the surface to be cleaned points towards the rear of the floor brush assembly 120. This allows the dry dirt picked up from the surface by the first cleaning component 122 to move orderly towards the rearward first suction port 130a under the influence of the tangential velocity direction and the airflow generated by the rotation, and smoothly enter the first suction port 130a under the negative pressure suction. Therefore, it can effectively reduce the possibility of dry dirt escaping away from the first suction port 130a, ensuring that the dry dirt always moves orderly towards the first suction port 130a, thereby improving the suction efficiency of dry cleaning, reducing the accumulation or leakage of dry dirt at the front end of the floor brush body 121, and improving the cleaning effect.

[0165] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the cleaning device 100 also includes a first suction assembly 180 and a dust box 160. A first air outlet is provided at the end of the first air duct 130 away from the first suction port 130a. The first air outlet is connected to the first suction assembly 180. The dust box 160 is located in the airflow path between the first suction port 130a and the first suction assembly 180.

[0166] In this embodiment, since the first air duct 130 and the second air duct 140 are isolated from each other, and the dust box 160 is connected to the airflow path of the first air duct 130, the dust box 160 can be used only to collect dry dirt from the first air duct 130. In other words, the dust box 160 can be configured as a collection container specifically for dry dirt from dry cleaning operations. Therefore, wet dirt such as wastewater generated from wet cleaning operations is transported independently through the second air duct 140 and cannot enter the dust box 160.

[0167] Therefore, the interior of the dustbin 160 can always maintain a dry environment, preventing dry dirt (such as hair, debris, and dust) from coming into contact with moisture or liquid. On one hand, dry dirt will not clump, mold, or stick to the inner wall of the dustbin 160 due to moisture absorption. When emptying the dustbin 160, the dirt can slide out smoothly without the need for scraping the inner wall with tools, reducing the difficulty of cleaning the dustbin 160 and improving the thoroughness and convenience of emptying. On the other hand, the filter components inside the dustbin 160 (such as HEPA filters and sponge filter layers) will not become damp, clogged, or breed bacteria due to contact with moisture. The filtration efficiency can remain stable over a long period, reducing the possibility of decreased suction power and frequent replacements due to moisture in the filter components. This helps to extend the service life of the filter components and reduce the user's maintenance costs.

[0168] See also some of the possible implementation methods. Figure 1 As shown, both the dustbin 160 and the first suction component 180 are disposed on the floor brush body 121. The first suction component 180 is disposed adjacent to the dustbin 160.

[0169] In this embodiment, the first air duct 130, dust box 160 and first suction component 180 are integrated inside the floor brush body 121 to form a compact dry cleaning module. This helps to reduce the volume and weight of the floor brush component 120, facilitates the lightweight design of the cleaning device 100, and improves the mobility and operational flexibility of the cleaning device 100 in low spaces (such as under furniture, under beds, etc.).

[0170] By integrating the first air duct 130, dust box 160, and first suction component 180 inside the brush body 121, the airflow path between the first suction port 130a, the first air duct 130, the dust box 160, and the first suction component 180 is significantly shortened. Specifically, the length and number of bends in the first air duct 130 can be reduced to effectively reduce the loss of negative pressure during transmission, allowing the suction force generated by the first suction component 180 to be transmitted to the first suction port 130a more efficiently. Under the same input power, the first suction component 180 can have stronger suction performance; or, under the same suction performance requirements, a lower power consumption suction component can be used, which helps to reduce the overall energy consumption of the machine. Furthermore, the first suction component 180 is positioned adjacent to the dust box 160, which allows the clean airflow after gas-solid separation in the dust box 160 to enter the first suction component 180 immediately after being discharged from the dust box 160, without needing to be transported through a long pipeline. This reduces secondary leakage or suction loss caused by poor pipeline sealing during the transport of clean airflow, and further improves pneumatic efficiency.

[0171] Furthermore, the first suction component 180 is located on the brush body 121, which significantly lowers the center of gravity of the entire machine and moves it forward to the brush component 120. On the one hand, lowering the center of gravity improves the stability of the cleaning device 100 during operation and posture switching, making it less likely for the brush component 120 to tilt or tip over when the user pushes the body 110. Especially when the brush component 120 rotates to switch cleaning postures, it effectively reduces the possibility of the cleaning device 100 tipping over, improving stability and safety. On the other hand, it reduces the weight of the body 110. The inertial torque and steering torque that the user needs to overcome when pushing the body 110 are correspondingly reduced, effectively reducing the pushing force and operating effort required to push the body 110, making cleaning operations more effortless and convenient. Especially for large homes or long-term continuous cleaning scenarios, it can effectively alleviate wrist and arm fatigue for users, improving product comfort.

[0172] In other examples, the dustbin 160 is located on the brush body 121, and the first suction assembly 180 is located on the body 110.

[0173] In this embodiment, the dust box 160, serving as a centralized collection container for dry dirt, is positioned on the brush body 121, significantly shortening the airflow path between the first suction port 130a, the first air duct 130, and the dust box 160. Dry dirt sucked in through the first suction port 130a can directly enter the dust box 160 with a shorter distance, effectively reducing particulate matter settling, wear on the inner wall of the first air duct 130, and dirt residue caused by long-distance transport of dirt within the first air duct 130. This improves the collection efficiency and thoroughness of dry dirt.

[0174] By mounting the first suction component 180 on the body 110, the overall weight distribution of the machine can be balanced, avoiding the problem of increased pushing resistance and reduced operational flexibility caused by an overly heavy floor brush component 120. Furthermore, the body 110 provides more space for the first suction component 180, which improves its heat dissipation efficiency, thereby enhancing the machine's continuous operating capacity and reliability.

[0175] In some examples, the relative positions of the dustbin 160 and the first suction assembly 180 can be adapted to the internal space of the floor brush body 121.

[0176] For example, the dust box 160 and the first suction component 180 can be stacked vertically, arranged side by side horizontally, or arranged front to back, and are not limited in this embodiment.

[0177] In some feasible ways, the second cleaning element 123 rotates about its own axis, and the axis of the second cleaning element 123 is parallel to the surface to be cleaned.

[0178] When the floor brush assembly 120 is in the first cleaning posture, the rotation direction of the second cleaning component 123 is opposite to the rotation direction of the auxiliary wheel 150. When the floor brush assembly 120 is in the second cleaning posture, the rotation direction of the second cleaning component 123 is the same as the rotation direction of the auxiliary wheel 150.

[0179] In this embodiment, the second cleaning component 123 can form continuous and uniform contact with the surface to be cleaned through its outer peripheral surface during operation, so as to effectively perform wet cleaning operations.

[0180] When the floor brush assembly 120 is in the first cleaning posture, the first cleaning component 122 is located in front of the second cleaning component 123. The second cleaning component 123 is a rear cleaning component, and its rotation direction is opposite to that of the auxiliary wheel 150. At this time, the tangential velocity direction of the contact part between the second cleaning component 123 and the surface to be cleaned points to the rear of the floor brush assembly 120. This allows the wastewater, wet mud, and other wet dirt generated during the wet operation of the second cleaning component 123 to be guided backward to the second suction port 140a located behind it. This reduces the splashing of wet dirt towards the area where the first cleaning component 122 is located, thereby effectively isolating the dry cleaning area from the wet cleaning area and reducing the possibility of the first cleaning component 122 and the first air duct 130 being contaminated by moisture.

[0181] When the floor brush assembly 120 is in the second cleaning posture, the second cleaning component 123 is located in front of the first cleaning component 122. As a front cleaning component, the second cleaning component 123 rotates in the same direction as the auxiliary wheel 150. At this time, the tangential velocity of the contact area between the second cleaning component 123 and the surface to be cleaned points towards the rear of the floor brush assembly 120, causing the wet dirt picked up by the second cleaning component 123 to move orderly and be smoothly sucked into the rearward second suction port 140a.

[0182] Therefore, by changing the rotation direction of the second cleaning component 123, the rotation direction of the second cleaning component 123 can be configured to guide wet dirt to the corresponding direction of the second suction port 140a when the floor brush assembly 120 is in the first cleaning posture or the second cleaning posture. This allows the second cleaning component 123 to efficiently pick up and directionally transport wet dirt in both the first and second cleaning postures, thereby reducing the possibility of secondary pollution or cleaning dead corners caused by wet dirt being pushed in the wrong direction due to posture switching. This is beneficial to improving the wet cleaning effect and reliability of the cleaning equipment 100 in various cleaning modes.

[0183] See also some of the possible implementation methods. Figure 1 and Figure 2As shown, the second suction port 140a is provided with a first opening 1401 and a second opening 1402. Along the front-rear direction X of the floor brush assembly 120, the first opening 1401 and the second opening 1402 are located on both sides of the second cleaning member 123, and the second opening 1402 is closer to the auxiliary wheel 150.

[0184] When the floor brush assembly 120 is in the first cleaning posture, the first opening 1401 is in the open state and the second opening 1402 is in the closed state. When the floor brush assembly 120 is in the second cleaning posture, the second opening 1402 is in the open state and the first opening 1401 is in the closed state.

[0185] In this embodiment, the second suction port 140a is provided with suction channels on both sides of the second cleaning member 123, so that when the floor brush assembly 120 is in the first cleaning posture or the second cleaning posture, an effective suction port (first opening 1401 or second opening 1402) can be provided on one side corresponding to the second cleaning member 123.

[0186] When the floor brush assembly 120 is in the first cleaning posture, the first cleaning component 122 is located in front of the second cleaning component 123. At this time, the second cleaning component 123 acts as a rear cleaning component, and the wet dirt generated by the wet operation of the second cleaning component 123 moves to the rear. Along the forward pushing direction of the floor brush assembly 120, the first opening 1401 located on the rear side can be in an open state, and the second opening 1402 located on the front side can be in a closed state, so that the second suction port 140a can only be suctioned through the first opening 1401 located on the rear side of the second cleaning component 123. This reduces the possibility of suction dispersion and negative pressure loss caused by the simultaneous opening of the first opening 1401 and the second opening 1402, and ensures that the suction negative pressure at the first opening 1401 on the rear side is concentrated and sufficient.

[0187] When the floor brush assembly 120 is in the second cleaning posture, the second cleaning component 123 is located in front of the first cleaning component 122. At this time, the second cleaning component 123 acts as a front cleaning component, and the wet dirt generated by the wet operation of the second cleaning component 123 moves to the rear. Along the forward pushing direction of the cleaning device 100, the second opening 1402 located at the rear is in the open state, and the first opening 1401 located at the front is in the closed state, so that the second suction port 140a can be suctioned only through the second opening 1402 located at the rear of the second cleaning component 123.

[0188] By selectively switching the opening and closing states of the first opening 1401 and the second opening 1402 according to the cleaning posture, when the floor brush assembly 120 is in the first cleaning posture or the second cleaning posture, the second suction port 140a always only opens the opening located on the rear side of the second cleaning component 123 (i.e., the downstream side in the direction of dirt movement). This ensures that wet dirt can enter the corresponding opening directly through a short path after being rolled up, thereby improving the cleaning effect. At the same time, it reduces the possibility of suction dispersion and negative pressure loss caused by the simultaneous opening of the first opening 1401 and the second opening 1402, which is conducive to improving the effective power utilization rate of the suction assembly.

[0189] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, a movable switch 141 is provided inside the second air duct 140. When the floor brush assembly 120 is in the first cleaning posture, the movable switch 141 closes the second opening 1402. When the floor brush assembly 120 is in the second cleaning posture, the movable switch 141 closes the first opening 1401.

[0190] In this embodiment of the application, the active switch 141 can be used to selectively close or open the first opening 1401 and the second opening 1402, so that no matter what cleaning posture the floor brush assembly 120 is in, the second suction port 140a can effectively suck up dirt only through a single opening located on the rear side of the second cleaning component 123.

[0191] In some examples, the second air duct 140 may have a first suction channel and a second suction channel in the portion near the second cleaning member 123.

[0192] In some examples, the movable switch 141 may include a movable baffle movably connected to the inner wall of the second air duct 140. The movable baffle may be rotatably connected to the inner wall of the second air duct 140, or it may be slidably connected to the inner wall of the second air duct 140; this is not limited in the embodiments of this application.

[0193] In this embodiment, the example described is that the active switch 141 is rotatably connected to the inner wall of the second air duct 140.

[0194] In some examples, there may be one movable baffle. When the free end of the movable baffle corresponds to the first suction channel, the movable baffle can close the first opening 1401, at which point the first opening 1401 is in a closed state and the second opening 1402 is in an open state. Similarly, when the free end of the movable baffle corresponds to the second suction channel, the movable baffle can close the second opening 1402, at which point the first opening 1401 is in an open state and the second opening 1402 is in a closed state.

[0195] Alternatively, there may be two movable baffles. One movable baffle corresponds to the first suction channel for closing or opening the first opening 1401. The other movable baffle corresponds to the second suction channel for closing or opening the second opening 1402.

[0196] In some examples, the switching of the position of the active switch 141 can be linked to the rotation of the floor brush assembly 120 relative to the body 110 to switch cleaning postures. When the floor brush assembly 120 switches to the first cleaning posture, the active switch 141 can automatically switch to the position that closes the second opening 1402. When the floor brush assembly 120 switches to the second cleaning posture, the active switch 141 can automatically switch to the position that closes the first opening 1401.

[0197] For example, when the floor brush assembly 120 rotates relative to the body 110 to switch cleaning postures, the rotational movement of the floor brush assembly 120 can be converted into position switching of the active switch 141 by a linkage mechanism. The linkage mechanism may include, but is not limited to, a toggle element that drives the position switching of the active switch 141, a power transmission assembly, etc. The power transmission assembly may be, but is not limited to, a rack and pinion mechanism, a linkage mechanism, or a cam mechanism.

[0198] Alternatively, the active switch 141 can be made of a magnetic material. Taking an active switch 141 including a movable baffle as an example, when the ground brush assembly 120 is in the first cleaning posture, the inner wall of the second suction channel can be energized, so that the inner wall of the second suction channel can attract the movable baffle and close the second opening 1402, thereby allowing the first opening 1401 to be in the open state. Similarly, when the ground brush assembly 120 is in the second cleaning posture, the inner wall of the first suction channel can be energized, so that the inner wall of the first suction channel can attract the movable baffle and close the first opening 1401, thereby allowing the second opening 1402 to be in the open state.

[0199] Furthermore, the opening of the first opening 1401 or the second opening 1402 can be controlled by a pneumatic control method using negative or positive pressure. The movable switch 141 contains a pneumatic chamber. The cleaning device 100 is equipped with an air source device. By controlling the air source device to fill the activation chamber with positive pressure or extract negative pressure, the movable switch 141 can be driven to switch positions, thereby closing the first opening 1401 or the second opening 1402.

[0200] See also some of the possible implementation methods. Figure 1 As shown, the cleaning device 100 also includes a second suction assembly 190 and a wastewater tank 170. A second air outlet is provided at the end of the second air duct 140 away from the second suction port 140a. The second air outlet is connected to the second suction assembly 190. The wastewater tank 170 is located in the airflow path between the second suction port 140a and the second suction assembly 190.

[0201] In this embodiment, the negative pressure generated by the second suction assembly 190 during operation is transmitted through the second air outlet to the second air duct 140 and the second suction port 140a, allowing wet wastewater, wet mud, and other wet contaminants generated by the wet operation of the second cleaning component 123 to be sucked into the second air duct 140 through the second suction port 140a. The wet contaminants are intercepted and collected in the wastewater tank 170 during the airflow process. The separated airflow is discharged from the second air duct 140 through the second air outlet and enters the second suction assembly 190, ultimately being discharged into the external environment.

[0202] The wet dirt is drawn into the sewage tank 170 after being sucked in through the second suction port 140a, where it undergoes gas-liquid separation. Moisture, droplets, and wet dust are trapped inside the sewage tank 170. The separated airflow is relatively dry and clean. Therefore, the gas entering the second suction assembly 190 carries a lower content of droplets and particulate matter, which can effectively reduce the entry of moisture and dirt into the second suction assembly 190, thus preventing problems such as moisture absorption, short circuits, corrosion, and impeller wear. This helps to extend the service life and operational reliability of the second suction assembly 190.

[0203] Furthermore, the wastewater tank 170 is positioned along the path of the second air duct 140, centralizing the collection of wet dirt. Users only need to clean the wastewater tank 170 to empty the wet dirt, eliminating the need for frequent cleaning of the interior of the second air duct 140. In addition, since the first air duct 130 and the second air duct 140 are isolated from each other, the dry cleaning dust box 160 and the wet cleaning wastewater tank 170 are independently configured. Dry and wet dirt are collected separately from the beginning. Users can empty the dust box 160 and the wastewater tank 170 separately to clean dry and wet dirt respectively, thereby reducing the cumbersome operation of additional solid-liquid separation required for mixed dry and wet dirt, improving maintenance convenience and user experience.

[0204] See also some of the possible implementation methods. Figure 1 As shown, both the wastewater tank 170 and the second suction assembly 190 are located on the body 110. The second suction assembly 190 is located adjacent to the wastewater tank 170.

[0205] In this embodiment, the wastewater tank 170 and the second suction component 190 are integrated inside the body 110, forming a compact wet cleaning module, which helps to reduce the overall size of the machine and improve the mobility and storage convenience of the cleaning equipment 100 in a small space.

[0206] Furthermore, the second suction component 190 is located adjacent to the sewage tank 170, which allows the airflow after gas-liquid separation in the sewage tank 170 to enter the second suction component 190 immediately after being discharged from the sewage tank 170, without the need for long-distance pipeline transportation. This reduces secondary leakage or suction loss of clean airflow during transportation due to poor pipeline sealing.

[0207] In addition, by integrating the wastewater tank 170 and the second suction component 190 inside the body 110, the weight of the floor brush component 120 can be reduced, thereby reducing the motion resistance of the floor brush component 120 when rotating relative to the body 110 and changing its posture, and improving the ease and smoothness of the user's operation of the floor brush component 120.

[0208] In some implementations, the auxiliary wheel 150 is a power-assisted wheel. There are two power-assisted wheels. The two power-assisted wheels are respectively positioned on opposite sides of the width direction (e.g., the Y-axis) of the floor brush assembly 120. The floor brush assembly 120 achieves steering through the differential rotation of the two power-assisted wheels.

[0209] In this embodiment, the two assist wheels can support the floor brush assembly 120 as it moves on the surface to be cleaned, and can also have an active driving assist function.

[0210] On one hand, the assist wheel provides driving force for pushing or pulling the floor brush assembly 120 forward or backward. When the user pushes the main body 110, only a small guiding force is required, and the assist wheel can drive the floor brush assembly 120 to move automatically following the user's direction of movement. Therefore, the pushing force required for the user to push the cleaning device 100 can be reduced. This is especially suitable for large homes or long-term continuous cleaning scenarios, effectively relieving wrist and arm fatigue and improving ease of operation and user comfort.

[0211] On the other hand, steering can be achieved by the differential rotation of the two assist wheels. When steering is required, the two assist wheels can be controlled to rotate at different speeds or in different directions. The steering torque is generated by the speed difference between the two assist wheels, so that the floor brush assembly 120 can complete the steering action on the surface to be cleaned without relying on the push-pull of the body 110 or the lateral sliding of the floor brush assembly 120.

[0212] By using the differential rotation of two assist wheels for reversing direction, the turning radius of the floor brush assembly 120 can be reduced, and even reversing direction on the spot can be achieved. This significantly improves the flexibility and maneuverability of the cleaning equipment 100 in confined spaces (such as between table and chair legs, furniture corners, narrow aisles, etc.), reduces blind spots, and lowers the possibility of the floor brush assembly 120 colliding with furniture or corners when the cleaning equipment 100 turns, thus reducing the risk of damage to the cleaning equipment 100 or furniture. In addition, the differential steering method eliminates the need for independent steering wheels or steering mechanisms, simplifying the structure of the floor brush assembly 120 and helping to reduce structural complexity and overall machine cost.

[0213] In some examples, along the front-rear direction X of the floor brush assembly 120, the auxiliary wheel 150 may be located in the middle area of ​​the floor brush assembly 120.

[0214] In some feasible ways, when the floor brush assembly 120 is in a first cleaning posture, the floor brush assembly 120 is configured with a switchable first cleaning mode and a second cleaning mode.

[0215] In the first cleaning mode, the first cleaning component 122 rotates while the second cleaning component 123 remains stationary. In the second cleaning mode, both the first cleaning component 122 and the second cleaning component 123 rotate.

[0216] In this application embodiment, the cleaning device 100 may be applied to, but is not limited to, the following scenarios.

[0217] When the local brush assembly 120 is in the first cleaning posture, the first cleaning component 122 for dry cleaning is located on the front side, and the second cleaning component 123 for wet cleaning is located on the rear side.

[0218] When only dry cleaning of the surface to be cleaned (such as hair, debris, and dust) is required, and wet cleaning is not necessary, the user can select the first cleaning mode. In the first cleaning mode, only the first cleaning component 122 rotates to perform dry cleaning, and the first suction component 180 operates to suck the dry dirt into the dust box 160 through the first suction port 130a, while the second cleaning component 123 remains stationary. This reduces unnecessary contact and friction between the second cleaning component 123 and the surface to be cleaned when wet cleaning is not required, thereby reducing the wear rate of the second cleaning component 123, extending its service life, and reducing the energy consumption and operating noise of the second cleaning component 123 during unused periods, which helps improve the overall energy efficiency of the machine.

[0219] When deep cleaning of the surface is required, or when cleaning a mixture of dry and wet dirt is needed, the user can select the second cleaning mode. In the second cleaning mode, both the first cleaning component 122 and the second cleaning component 123 rotate. The first cleaning component 122 can first perform dry cleaning on the surface to be cleaned, effectively picking up and removing dry dirt such as hair, debris, and dust. Subsequently, the second cleaning component 123 performs wet cleaning on the surface after dry cleaning. The rotating second cleaning component 123, in conjunction with liquid supply, performs a mopping operation to remove stubborn stains such as water stains, fine dust, and residual oil. This setup allows for the orderly connection and coordinated operation of dry and wet cleaning within the same cleaning cycle. Dry cleaning first prevents dry dirt from clumping when it comes into contact with water, while wet cleaning afterwards ensures a deep cleaning effect. The two work together without interference, saving cleaning time and reducing energy consumption, saving user operation time and reducing fatigue, thereby improving cleaning efficiency while ensuring cleaning effectiveness. It is especially suitable for complex cleaning scenarios where dry and wet stains coexist, such as kitchens and restaurants.

[0220] Furthermore, when the local brush assembly 120 is in the second cleaning posture, the second cleaning component 123 for wet cleaning is located on the front side, and the first cleaning component 122 for dry cleaning is located on the rear side.

[0221] When only wet cleaning of wet dirt (such as water stains) is required on the surface to be cleaned, and dry cleaning is not necessary, the floor brush assembly 120 can be controlled to adjust to the second cleaning posture. At this time, only the second cleaning component 123 rotates to perform wet cleaning, and the second suction assembly 190 works to suck the wet dirt into the wastewater tank 170 through the second suction port 140a, while the first cleaning component 122 remains stationary. This reduces unnecessary contact and friction between the first cleaning component 122 and the surface to be cleaned when wet cleaning is not required, thereby reducing the wear rate of the first cleaning component 122, extending its service life, and reducing the energy consumption and operating noise of the first cleaning component 122 during unused periods, which helps to improve the overall energy efficiency of the machine.

[0222] In some examples, users can switch between a first cleaning mode and a second cleaning mode by applying a steering force to the floor brush assembly 120. Alternatively, users can control the floor brush assembly 120 to automatically rotate relative to the body 110 using operation buttons on the body 110. These operation buttons on the body 110 may be, but are not limited to, buttons, knobs, touch panels, etc.

[0223] In some examples, the cleaning device 100 may also be equipped with a dirt detection device. The control unit can automatically select a first cleaning posture or a second cleaning posture, as well as a first cleaning mode or a second cleaning mode, based on the type of dirt detected by the dirt detection device. This enables intelligent automatic switching of cleaning posture and cleaning mode, thereby improving user convenience and the degree of cleaning automation.

[0224] For example, the dirt detection device may be, but is not limited to, an optical sensor, an ultrasonic sensor, etc.

[0225] In some possible implementations, the first cleaning element 122 is vertically connected to the floor brush body 121 to have a lowered position and an raised position.

[0226] When the first cleaning component 122 is in the lowered position, the first cleaning component 122 is in contact with the surface to be cleaned; when the first cleaning component 122 is in the raised position, the first cleaning component 122 is not in contact with the surface to be cleaned.

[0227] When the floor brush assembly 120 is in the first cleaning posture and is running in the forward direction, the first cleaning component 122 is in the lowered position. When the floor brush assembly 120 is in the second cleaning mode and is running in the backward direction, and when the floor brush assembly 120 is in the second cleaning posture, the first cleaning component 122 is in the raised position.

[0228] In this embodiment, the working state of the first cleaning component 122 can be adjusted according to the cleaning posture and running direction of the floor brush assembly 120 to effectively ensure the isolation and switching reliability between dry cleaning and wet cleaning.

[0229] When the ground brush assembly 120 is in the first cleaning posture and is running in the forward direction, the first cleaning component 122 is in the descending position and in contact with the surface to be cleaned. At this time, the first cleaning component 122 performs dry cleaning operation as a front cleaning component to effectively pick up and clean dry dirt such as hair and debris on the travel path, and cooperates with the first suction port 130a to suck the dry dirt into the dust box 160.

[0230] When the floor brush assembly 120 is in the first cleaning posture, the second cleaning component 123, as a rear-mounted cleaning component, can be in a non-working state or perform wet cleaning operations according to application requirements. When the floor brush is recently in the first cleaning mode, the second cleaning component 123 remains stationary in a non-working state and can remain dry. When the floor brush assembly 120 moves in the backward direction, the first cleaning component 122 can remain in the lowered position to perform reciprocating cleaning of the surface to be cleaned. When the floor brush assembly 120 is in the second cleaning mode, the second cleaning component 123 rotates to be in the working state. When the floor brush assembly 120 moves in the forward direction, it can perform dry and wet cleaning on the surface to be cleaned. The second cleaning component 123 remains wet. When the floor brush moves in the backward direction, the first cleaning component 122 can switch from the lowered position to the raised position to disengage from the surface to be cleaned.

[0231] Specifically, when the floor brush assembly 120 is in the second cleaning mode and moving backward, the second cleaning component 123 performs wet cleaning, leaving damp mopping marks and liquid on the surface to be cleaned. If the first cleaning component 122 is still in the descending position, as the floor brush assembly 120 is pulled backward, the first cleaning component 122 directly contacts the surface to be cleaned after wet mopping, and the bristles on the first cleaning component 122 quickly absorb the residual moisture, liquid, and wet dirt on the floor. On the one hand, after the first cleaning component 122 absorbs water and becomes damp, the bristles become soft, clump, or stick together. When switching back to the first cleaning posture to perform dry cleaning, the damp bristles are unable to effectively pick up hair, debris, and other dry dirt, and the excessive humidity may even cause the dry dirt to stick to the bristles and be difficult to remove, affecting the dry cleaning effect. On the other hand, during the rotation of the first cleaning component 122, which absorbs moisture, the moisture and wet dirt it carries will enter the first air duct 130 through the first suction port 130a with the airflow, causing an adhesive layer to form on the inner wall of the first air duct 130, which is difficult to clean. In addition, moisture can also invade the dust box 160, causing the dry dirt already collected in the dust box 160 to become damp and clump together. Moisture can even enter the first suction assembly 180 along the first air duct 130, causing the first suction assembly 180 to become damp, short-circuit, or malfunction.

[0232] Therefore, by raising the first cleaning component 122 to a point where it is no longer in contact with the surface to be cleaned when the first cleaning component 122 is in the second cleaning mode and is pulled back, this application can reduce the possibility of the first cleaning component 122 coming into contact with the surface to be cleaned after wet mopping. This effectively avoids the problem of the first cleaning component 122 getting damp and the first air duct 130 being contaminated by moisture, so that the first cleaning component 122 always remains dry and clean when switching back to dry cleaning, thus ensuring the continuous stability of the dry cleaning effect. It can also reduce the possibility of moisture intrusion into the first air duct 130 and the first suction component 180 causing the cleaning equipment 100 to malfunction.

[0233] Similarly, when the ground brush assembly 120 is in the second cleaning posture, the second cleaning component 123 is located in front of the first cleaning component 122 as a front cleaning component to perform wet cleaning operations, while the first cleaning component 122 is located behind the second cleaning component 123. After the second cleaning component 123 passes, wet mopping marks are left on the surface to be cleaned. By switching the first cleaning component 122 to the raised position and separating it from the surface to be cleaned, the risk of the first cleaning component 122 coming into contact with the wet cleaning area and becoming damp, as well as the risk of moisture entering the first air duct 130 through the first suction port 130a, can be avoided, thus ensuring effective isolation between dry cleaning and wet cleaning in the second cleaning posture.

[0234] In some examples, the first cleaning component 122 may be vertically connected to the brush body 121 via a transmission structure such as a cam mechanism, a lead screw and nut mechanism, or a linkage mechanism.

[0235] For example, the floor brush body 121 is provided with a rotatable cam. A mating part is provided between the cam and the bracket of the first cleaning member 122. When the cam rotates to a first angle position, the protrusion of the cam abuts against the mating part and pushes the bracket of the first cleaning member 122 to a lowered position, so that the first cleaning member 122 contacts the surface to be cleaned. When the cam rotates to a second angle position, the base circle of the cam is opposite to the mating part, and the bracket of the first cleaning member 122 can be lifted to a raised position under the action of the elastic reset member, so that the first cleaning member 122 is disengaged from the surface to be cleaned.

[0236] This application also provides a cleaning system, see [link to relevant documentation] Figure 3 and Figure 4 As shown, the cleaning system may include the cleaning device 100 and the base station 200 in any of the above embodiments. The cleaning device 100 may be placed on the base station 200.

[0237] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, the base station 200 includes a first storage container 210 and a second storage container 220 that are not connected to each other. The first storage container 210 is connected to the dust box 160 of the cleaning equipment 100. The second storage container 220 is connected to the wastewater tank 170 of the cleaning equipment 100.

[0238] In this embodiment, when the base station 200 receives the dirt collected by the cleaning equipment 100, it can connect to the dry dust collection box 160 and the wet wastewater collection tank 170 of the cleaning equipment 100 respectively without connecting the first storage container 210 and the second storage container 220, so as to achieve the separation and partitioned storage of dry dirt and wet dirt on the base station 200 side.

[0239] The first storage container 210 is used only to receive and store dry dirt from the dust box 160, and the second storage container 220 is used only to receive and store wet dirt from the wastewater tank 170. The first storage container 210 and the second storage container 220 are not connected to each other, which ensures that dry dirt and wet dirt remain separated throughout the entire process from discharge from the cleaning equipment 100 to collection by the base station 200. This effectively reduces the possibility of problems such as clumping, mold, odor, and bacterial growth caused by mixed dry and wet dirt, and ensures the cleanliness and hygiene of the internal environment of the cleaning equipment 100 and the base station 200.

[0240] Furthermore, when cleaning the base station 200, users can empty the dry dirt in the first storage container 210 and the wet dirt in the second storage container 220 respectively, without having to perform additional separation operations on the mixed dirt, thus simplifying the cleaning process and improving maintenance convenience.

[0241] Furthermore, the first storage container 210 and the second storage container 220 are each independently configured, allowing users to clean one of them separately based on actual usage. For example, when the first storage container 210 is full while the second storage container 220 is not full, the user only needs to clean the first storage container 210, without simultaneously cleaning the second storage container 220, thus reducing unnecessary maintenance frequency and improving usability. The independently configured first and second storage containers 210 and 220 can be cleaned and disinfected separately, reducing the hygiene risks caused by cross-contamination of dry and wet dirt due to mixed storage.

[0242] See in some examples Figure 4 As shown, dry dirt in the dust box 160 of the cleaning device 100 can enter the base station 200 from point M and enter the first storage container 210 under the action of gravity.

[0243] In some examples, dry dirt can be filtered out by a filter structure such as a filter screen before entering the first receiving container 210, so that larger particles of dry dirt can be removed.

[0244] In some examples, base station 200 may be provided with a clean water tank 240. The clean water tank 240 may at least be used to provide cleaning fluid for the self-cleaning of the first cleaning component 122 and the second cleaning component 123 of the cleaning device 100.

[0245] In some examples, the clean water tank 240 is not connected to either the first storage container 210 or the second storage container 220.

[0246] For example, the clean water tank 240 and the second storage container 220 can be arranged side by side along the width direction Y of the cleaning device 100.

[0247] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, the second storage container 220 is equipped with a filter element 230. The filter element 230 divides the internal space of the second storage container 220 into a first cavity 220a and a second cavity 220b that are interconnected. The filter element 230 is used to block and retain solid waste generated by wet cleaning in the first cavity 220a, and to allow wastewater to flow through the filter element 230 into the second cavity 220b.

[0248] In this embodiment, the wet dirt discharged from the wastewater tank 170 of the cleaning device 100 enters the second storage container 220 and can first enter the first cavity 220a. When the wet dirt passes through the filter element 230, solid dirt (such as hair, food residue, mud, etc.) in the wet dirt can be intercepted by the filter element 230 and retained in the first cavity 220a, while liquid dirt can pass through the filter element 230 and flow into the second cavity 220b, realizing solid-liquid separation and partitioned storage of wet dirt on the base station 200 side.

[0249] Specifically, see Figure 4 As shown, the first cavity 220a can be located above the second cavity 220b. Wet dirt can enter the second storage container 220 of the base station 200 from point N. The wet dirt flows downwards under gravity, while solid dirt is retained in the first cavity 220a by the filter element 230, and liquid dirt is stored in the second cavity 220b under gravity. This effectively reduces the problems of rotting, foul odor, and bacterial growth caused by solid dirt being soaked in liquid dirt for a long time, thus reducing the possibility of odor generation inside the base station 200. Furthermore, when the user cleans the base station 200, solid and liquid dirt are located in different cavities, allowing the user to empty the solid and liquid dirt separately without requiring additional solid-liquid separation of the mixed dirt.

[0250] In some examples, filter element 230 may be, but is not limited to, a screen, filter plate, filter membrane, perforated baffle, etc.

[0251] In some examples, spray self-cleaning components are integrated inside both the base station 200 and the wastewater tank 170. When the cleaning device 100 is placed back in the base station 200, the base station 200 can automatically start the spray cleaning program, using high-pressure water jets to flush the inner wall of the wastewater tank 170 of the body 110, so as to thoroughly remove stains, slime and dirt residue remaining on the inner wall of the wastewater tank 170.

[0252] After completing the cleaning operation and returning to the base station 200, the cleaning equipment 100 can automatically perform the self-cleaning process inside the sewage tank 170 without manual intervention from the user. Through the spraying and rinsing of high-pressure water, stubborn residues such as oil, grime, mucus, and bacterial biofilms adhering to the inner wall of the sewage tank 170 are effectively peeled off and removed, so as to avoid odor, mold and bacterial growth caused by the accumulation of dirt in the sewage tank 170 after long-term use, and ensure the long-term cleanliness and hygiene of the inside of the sewage tank 170.

[0253] Furthermore, the spray self-cleaning component is integrated inside the base station 200 and the wastewater tank 170 cavity, which allows the entire wet cleaning process to be completed automatically in a closed environment. The entire process does not require manual washing or wiping by the user, reducing or even eliminating the user's maintenance burden of cleaning the wastewater tank 170, and realizing full-dimensional manual maintenance-free operation of the wet cleaning system.

[0254] This application embodiment also provides a control method for a cleaning device, the cleaning device including a body, a floor brush assembly, a first air duct, a second air duct, and auxiliary wheels;

[0255] The floor brush assembly is rotatably connected to the main body and can rotate on the surface to be cleaned, having at least a first cleaning posture and a second cleaning posture. When the floor brush assembly is in the first cleaning posture along its forward pushing direction, the first cleaning component is located in front of the second cleaning component. When the floor brush assembly is in the second cleaning posture, the second cleaning component is located in front of the first cleaning component.

[0256] The floor brush assembly includes a floor brush body and a first cleaning component and a second cleaning component disposed on the floor brush body. The first and second cleaning components are arranged side by side along the front-to-back direction of the floor brush assembly. The first cleaning component is used for dry cleaning of the surface to be cleaned, and the second cleaning component is used for wet cleaning of the surface to be cleaned. A first air duct is used to extract dirt generated during the dry cleaning operation of the first cleaning component. A second air duct is used to extract dirt generated during the wet cleaning operation of the second cleaning component. The first and second air ducts are isolated from each other. An auxiliary wheel is disposed on the floor brush body, and the auxiliary wheel supports the floor brush assembly to move on the surface to be cleaned.

[0257] The methods include:

[0258] In response to a rotation request for the floor brush assembly, the floor brush assembly is controlled to rotate relative to the body to present a first target cleaning posture corresponding to the rotation request. The first target cleaning posture may include a first cleaning posture or a second cleaning posture.

[0259] The rotation request refers to a rotation control request issued to the floor brush assembly, which triggers the floor brush assembly to rotate relative to the body and assume a corresponding target cleaning posture. The first target cleaning posture is the target posture corresponding to the rotation request, and its value is either the first cleaning posture or the second cleaning posture, which is used as the target stopping position of the floor brush assembly after it has completed rotation.

[0260] In this embodiment, through the rotatable connection between the body and the floor brush assembly, the first and second cleaning components arranged side by side on the floor brush body, and the first and second air ducts respectively used to suck up dirt generated during the operation of the first and second cleaning components and isolated from each other, the cleaning device responds to the received rotation request, first determines the first target cleaning posture corresponding to the rotation request, and then controls the floor brush assembly to rotate relative to the body to the first target cleaning posture, so that the first cleaning component of the floor brush assembly is located in front of the second cleaning component in the first cleaning posture, or the second cleaning component is located in front of the first cleaning component in the second cleaning posture.

[0261] The same floor brush assembly can switch cleaning postures based on the user's rotation request simply by rotating itself, and maintains the corresponding cleaning component and air duct coordination after the posture switch. Specifically, the first cleaning component and the first air duct work together to achieve dry cleaning, while the second cleaning component and the second air duct work together to achieve wet cleaning. This setup ensures that dry and wet dirt are transported and collected separately in their respective cleaning areas and isolated air ducts, allowing for separation and processing of dry and wet dirt from the source of suction. This effectively reduces the possibility of dry and wet dirt mixing and accumulating within the floor brush assembly, clogging the air ducts, and thus ensures the long-term unobstructed flow of the suction channel, improving the reliability of the cleaning equipment and increasing cleaning efficiency. Furthermore, the coordination between the corresponding cleaning component and the corresponding air duct is automatically established after the floor brush assembly posture switch, requiring no additional settings or adjustments from the user, making operation simple and convenient.

[0262] In some examples, since the first and second cleaning components are arranged side by side along the front-to-back direction on the brush body, when determining the target posture, the cleaning component located on the front side can be identified as the first or second cleaning component, and the working position of the corresponding first or second air duct in the subsequent cleaning process can be determined.

[0263] In some feasible implementations, the rotation request is generated by the cleaning equipment in response to a user's preset rotation operation.

[0264] The preset rotation operation includes triggering a preset button on the cleaning device and / or applying an adjustment operation to the floor brush assembly, causing it to rotate around the machine body.

[0265] In this embodiment, users can switch the attitude of the floor brush component through at least one of two methods: preset button triggering (such as pressing / rotating the button, sending commands through the application, voice control, etc.) and manual force adjustment, so as to meet the diverse needs of different application scenarios and user habits.

[0266] Specifically, when triggered by a preset button, the device can quickly switch between cleaning postures with a single click. The cleaning equipment can automatically control the floor brush assembly to rotate to the corresponding target cleaning posture, making operation simple and effortless. When adjusted manually, the rotation angle of the floor brush assembly relative to the body can be quickly and finely adjusted to handle cleaning of local corners. Furthermore, external force can be applied directly to the floor brush assembly for manual adjustment, without the need to operate buttons or wait for an electric response, making adjustments more intuitive and efficient.

[0267] It is easy to understand that the preset button trigger and manual force adjustment can be used together to control the cleaning posture switching of the floor brush component. This ensures the convenience and flexibility of cleaning posture switching, and in special cases such as electric drive failure or insufficient power, the cleaning posture can still be switched manually, enhancing the fault tolerance and emergency availability of the cleaning equipment.

[0268] In some feasible implementations, before controlling the rotation of the brush assembly relative to the body to present the target cleaning posture corresponding to the rotation request, the following steps are also included:

[0269] Obtain the current cleaning state of the cleaning scene and the floor brush component. The cleaning scene includes:

[0270] Based on the cleaning scenario, a second target cleaning posture is determined. This second target cleaning posture can be either the first cleaning posture or the second cleaning posture.

[0271] A rotation request is generated based on the current cleaning posture and the second target cleaning posture.

[0272] In this embodiment, the cleaning posture switching of the floor brush component can be based on the automatic identification of the cleaning scene and the comprehensive judgment of the current cleaning posture to generate a rotation request autonomously, so as to realize intelligent decision-making and automatic switching of the cleaning posture.

[0273] Specifically, the cleaning equipment first obtains the current cleaning scene information (such as the type of floor material, type of dirt, degree of dirt, etc. of the area to be cleaned), then determines the optimal cleaning posture (i.e. the second target cleaning posture) to match the cleaning scene, and then compares the second target cleaning posture with the current cleaning posture of the floor brush component. If the two are inconsistent, a rotation request is automatically generated and the floor brush component is driven to rotate to the target cleaning posture.

[0274] With this setup, the cleaning equipment can adaptively select the optimal cleaning posture according to the actual cleaning scenario, without requiring manual judgment or operation by the user. It is especially suitable for fully automatic cleaning modes or scenarios where users are unfamiliar with the cleaning parameters, thereby improving the intelligence level and cleaning effect of the cleaning equipment.

[0275] Furthermore, by acquiring the current cleaning posture and comparing it with the target cleaning posture, the control unit can determine whether a posture switch is indeed necessary before generating a rotation request. This avoids unnecessary repeated rotations or malfunctions when already in the target posture, reducing wasted power consumption and mechanical wear of the drive motor. In addition, not generating a rotation request when already in the target cleaning posture also prevents unnecessary rotation of the floor brush assembly from interfering with the user's operating experience, avoiding the user's perception of a cleaning equipment malfunction and impacting their experience.

[0276] In some feasible ways, when the ground brush assembly is in the first cleaning posture, the rotation direction of the second cleaning component is controlled to be opposite to the rotation direction of the auxiliary wheel.

[0277] When the ground brush assembly is in the second cleaning posture, the rotation direction of the second cleaning component is controlled to be the same as the rotation direction of the auxiliary wheel.

[0278] In this embodiment, in the first cleaning posture, the first cleaning component is located in front of the second cleaning component, and the second cleaning component performs wet cleaning as a rear cleaning component. The tangential velocity direction of the part of the second cleaning component that contacts the surface to be cleaned is directed towards the rear of the floor brush assembly, so that the wet dirt generated by the wet cleaning is guided backward to the second suction port located behind the second cleaning component, thereby reducing the possibility of wet dirt splashing forward to the area where the first cleaning component is located, and ensuring effective isolation between the dry cleaning and wet cleaning areas.

[0279] In the second cleaning posture, the second cleaning component is located in front of the first cleaning component. The second cleaning component performs wet cleaning as a front cleaning component. The tangential velocity direction of the part in contact with the surface to be cleaned is also pointing to the rear of the floor brush assembly, so that the wet dirt is guided backward to the second suction port located behind the second cleaning component.

[0280] Therefore, based on the current cleaning posture of the floor brush assembly, the control unit automatically configures the rotation direction of the second cleaning component so that the tangential velocity direction of the part in contact with the surface to be cleaned always points in the direction of the second suction port. Thus, regardless of whether the floor brush assembly is in the first or second cleaning posture, the wet dirt generated by wet cleaning can obtain an orderly movement trend toward the second suction port, ensuring efficient suction of wet dirt, reducing secondary pollution or cleaning dead spots caused by wet dirt being pushed in the wrong direction due to the switching of cleaning posture, and improving the wet cleaning effect and reliability of the cleaning equipment in various cleaning modes.
