Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and specifically to a cleaning base, a cleaning system, and a cleaning control method. Background Art

[0002] Currently, driven by the rapid development of smart home technology and the continuous upgrading of consumption, smart cleaning devices represented by sweeping robots, floor scrubbers, and sweeping and mopping machines have become increasingly popular and have become an indispensable standard configuration for modern families due to their automation and efficiency. In related technologies, in order to effectively deal with traditional cleaning difficulties such as corners, furniture edges, and gaps under low furniture that are common in home environments, floor scrubbers have added side brushes. The core of this mechanism is to arrange side brushes on the extension of the floor brush of the floor scrubber. The side brushes can be closer to the corners than the main roller brush of the floor scrubber. Although this setting increases the cleaning range, users not only need to clean the main roller brush, but also have to spend extra time and energy to clean the side brushes specifically. This additional cleaning step significantly increases the user's usage burden and maintenance complexity, ultimately resulting in a negative impact on the overall product experience and may even weaken the user's core expectation of the convenience of smart cleaning devices. Summary of the Invention

[0003] Multiple embodiments of the present application provide a cleaning base, a cleaning system, and a cleaning control method, which can solve the problem of self-cleaning of the side brushes after cleaning in areas adjacent to walls and low spaces.

[0004] In the first aspect, an embodiment of the present application provides a cleaning base for docking a cleaning device, the cleaning base comprising an outer shell, the outer shell being provided with a first cleaning slot and a second cleaning slot, the first cleaning slot being used to carry a first cleaning part of the cleaning device, and the second cleaning slot being used to carry a second cleaning part of the cleaning device; the outer shell being provided with a connecting channel, the input port of the connecting channel being connected to the second cleaning slot, and the output port of the connecting channel being located around or inside the first cleaning slot; it should be noted that the area around the first cleaning slot includes but is not limited to a range within 5 cm from the edge of the first cleaning slot, and may also include a boundary range where the negative pressure of the airflow near the first cleaning slot exceeds a predetermined limit.

[0005] When the cleaning device is docked with the cleaning base, the sewage suction port of the cleaning device is located around or inside the first cleaning tank, so that the sewage suction port can generate suction on the first cleaning tank and the output port of the connecting channel.

[0006] At present, cleaning equipment generally has only one negative pressure suction component to form a sewage suction port. This easily leads to the situation that when two cleaning slots appear on the cleaning base, the cleaning equipment generally cannot suction the two cleaning slots at the same time. The sewage suction port is close to the first cleaning slot and can generate a large suction force on the first cleaning slot, but it is also relatively far away from the second cleaning slot, so that the suction force near the second cleaning slot is insufficient to support the dirt in it to be extracted, thereby failing to achieve integrated cleaning. However, the present application, without adding a new negative pressure suction component in advance, connects the first cleaning slot and the second cleaning slot to each other through a connecting channel, so that the negative pressure suction generated by the sewage suction port at the first cleaning slot can be transmitted to the second cleaning slot through the connecting channel, and then the dirt in the second cleaning slot can be sucked in by the same sewage suction port through the connecting channel, thereby achieving simultaneous suction processing of the dirt in the two cleaning slots.

[0007] Optionally, the cleaning device is provided with a floor brush assembly and a body assembly, the floor brush assembly is rotatably connected to the body assembly, the floor brush assembly is provided with a floor scraping strip, the first cleaning member is a roller brush, the floor scraping strip maintains a certain gap with the first cleaning member, the sewage suction port is arranged opposite to the first cleaning member, the floor scraping strip extends to the periphery of the sewage suction port, so that the gap between the floor scraping strip and the first cleaning member can generate suction under the action of the sewage suction port;

[0008] When the cleaning device is docked with the cleaning base, the output port of the connecting channel is located in the gap between the ground scraping strip and the first cleaning member, so that the output port of the connecting channel can generate suction.

[0009] In this way, the floor scraping strip of the floor brush assembly extends toward the sewage suction port to form a diversion structure, which facilitates the transmission of the negative pressure generated by the sewage suction port to the corresponding supporting surface along the extension direction of the floor scraping strip. The area with the largest suction force on the supporting surface is between the floor scraping strip and the first cleaning member. Adjusting the output port of the connecting channel to this area can enable the connecting channel to obtain greater suction force, thereby enhancing the sewage discharge capacity of the second cleaning tank.

[0010] Optionally, the ground scraping strip is provided with an avoidance portion, and the avoidance portion is used to leave a transition flow space for the fluid in the connecting channel to flow toward the sewage suction port;

[0011] When the cleaning device is docked with the cleaning base, the ground scraper contacts the first cleaning tank or the outer shell, the avoidance portion surrounds the outer peripheral side of the output port of the connecting channel, and the fluid output from the output port of the connecting channel enters the sewage suction port through the avoidance portion.

[0012] Since the gap between the floor scraper and the first cleaning member is very small, it is generally larger than the size of the output port of the connecting channel, which easily leads to the output port not being completely covered by the gap, thereby weakening the suction force of the output port. Therefore, it is necessary to improve the floor scraper to adapt to the corresponding output port without affecting the basic function of the floor scraper. In this solution, the floor scraper makes room for the output port of the connecting channel by providing an avoidance portion, and the avoidance portion is close to the output port, so that the sewage discharged from the output port of the connecting channel can enter the sewage suction port through the avoidance portion.

[0013] Optionally, the sewage suction port is located above the middle of the ground scraping strip, the avoidance portion is located in the middle of the ground scraping strip and has a U-shaped structure, and the avoidance portion has the function of scraping water on the ground.

[0014] This allows the escape to transfer the negative pressure from the suction port to the connecting channel, while also providing a floor-scraping function without compromising cleaning efficiency. Suction is strongest near the middle of the scraper blade, where the escape is located, and its U-shaped structure ensures that dirt on both sides of the suction port can be drawn in when the scraper blade is cleaning the floor. The U-shaped structure also creates more space between the suction port and the connecting channel.

[0015] Optionally, the first cleaning slot and the second cleaning slot are arranged on the shell along the front-to-back direction of the cleaning base, the second cleaning slot is set toward the left or right side of the shell, the input port of the connecting channel is connected to the bottom of the second cleaning slot, and the output port of the connecting channel extends toward the middle position of the first cleaning slot.

[0016] In this way, the positions of the first cleaning slot and the second cleaning slot correspond to and match the positions of the first cleaning member and the second cleaning member on the floor brush assembly.

[0017] Optionally, the connecting channel is arranged at an inclination, the bottom height of the second cleaning tank is greater than the top height of the first cleaning tank, or the connecting channel extends at a slope of 5° to 15°.

[0018] In this way, the connecting channel can form a certain slope, which makes it easier for the dirt in the second cleaning tank to flow to the location of the first cleaning tank through the connecting channel under the action of gravity.

[0019] Optionally, the second cleaning member is rotatably disposed on the floor brush assembly of the cleaning device, and one or more scrapers are provided at the bottom of the second cleaning tank, and the scrapers extend from the side walls of the second cleaning tank toward the center of the tank bottom;

[0020] When the cleaning device is docked with the cleaning base, the wiper is in interference contact with the second cleaning member.

[0021] In this way, dirt and sewage on the second cleaning member are scraped off by the wiper blade, thereby cleaning the second cleaning member.

[0022] Optionally, the side wall of the second cleaning tank is provided with an air outlet, and the air outlet is lower than the top surface height of the wiper, or, when the cleaning device is docked with the cleaning base, the air outlet is located below the second cleaning member.

[0023] In this way, after the second cleaning element is flushed and cleaned, the air outlet can blow out dry air to take away excess moisture, so that the second cleaning element and the second cleaning tank are dried quickly, effectively inhibiting the growth of bacteria.

[0024] Optionally, the bottom of the second cleaning tank is funnel-shaped, the lowest point of the second cleaning tank is located at the center of the bottom, and the input port of the connecting channel is set at the lowest point of the second cleaning tank; when the cleaning equipment is docked with the cleaning base, the rotation center of the second cleaning member is located above the center of the bottom of the second cleaning tank.

[0026] Optionally, the second cleaning member includes a rag and a tray, the rag is mounted on the tray and is in a circular ring shape; when the cleaning device is docked with the cleaning base, the inner ring area of ​​the rag is located directly above the input port of the connecting channel, and the wiper spans the ring width of the rag.

[0027] This ensures that the wiper blade can completely scrape the entire cloth during self-cleaning, ensuring the self-cleaning efficiency of the cloth. The wiper blade spans the width of the cloth ring and can quickly squeeze out water.

[0028] Optionally, the cleaning base further includes a base water pump, the second cleaning tank is provided with a spraying member, the base water pump is connected to the spraying member, the spraying member includes a first water spraying member and a second water spraying member, the first water spraying member is used to spray upward to wet the second cleaning member, and the second water spraying member is used to spray toward or along the tank bottom to rinse the second cleaning tank;

[0029] The base water pump supplies water to the injection member by being connected to a base station water tank provided on the cleaning base, or the base water pump supplies water to the injection member by being connected to an external water source.

[0030] In this way, the arrangement of the spraying member can improve the self-cleaning effect of the cleaning device. The first spraying member sprays upward to wet the second cleaning member, which can assist in cleaning the second cleaning member; the second spraying member can spray horizontally toward or along the bottom of the tank, thereby flushing the second cleaning tank.

[0031] Optionally, the housing includes a carrying panel for carrying the cleaning equipment, the first cleaning tank and the second cleaning tank are arranged on the carrying panel, the connecting channel is located below the carrying panel or attached to the lower surface of the carrying panel, and the input port and output port of the connecting channel are both facing upward.

[0032] In this way, it is convenient to place the cleaning device on the cleaning base for self-cleaning.

[0033] Optionally, the connecting channel is provided with a one-way valve, and the one-way valve is conductive in the direction from the input port to the output port.

[0034] In this way, it is ensured that the sewage can only flow from the second cleaning tank to the first cleaning tank, preventing sewage from flowing back.

[0035] Optionally, the cleaning base includes a fan and an air duct arranged in the shell, the fan is used to generate airflow, and the air duct is at least used to guide the airflow generated by the fan into the second cleaning tank.

[0036] In this way, the drying of the first cleaning tank and the second cleaning tank can be accelerated, and the growth of bacteria can be suppressed.

[0037] Optionally, the air duct is also used to introduce the airflow generated by the fan into the first cleaning tank, and the air duct includes a first air duct, a second air duct and a third air duct. The first air duct is used to divert the airflow generated by the fan to the second air duct and the third air duct, the second air duct connects the first cleaning tank and the first air duct, and the third air duct connects the second cleaning tank and the first air duct.

[0038] In this way, different cleaning tanks can be dried through different air ducts.

[0039] Optionally, the cleaning base includes a heating element arranged in the first air duct, and the heating element is used to heat the air flowing through the cleaning base.

[0040] In this way, the cleaning tank can be dried more quickly to avoid the problem of moisture, bacterial growth and odor.

[0041] In a second aspect, an embodiment of the present application provides a cleaning base for docking a cleaning device, the cleaning base comprising a housing, the housing being provided with a first cleaning slot and a second cleaning slot, the first cleaning slot being used to carry a first cleaning member of the cleaning device, the second cleaning slot being used to carry a second cleaning member of the cleaning device; the housing being provided with a connecting channel, the input port of the connecting channel being in communication with the second cleaning slot, and the output port of the connecting channel being located around or within the first cleaning slot;

[0048] When the cleaning device is docked with the cleaning base, the wiper is in interference contact with the second cleaning member.

[0049] Optionally, the side wall of the second cleaning tank is provided with an air outlet, the air outlet is lower than the top surface height of the wiper, or, when the cleaning device is docked with the cleaning base, the air outlet is located below the second cleaning member;

[0050] The bottom of the second cleaning tank is funnel-shaped, the lowest point of the second cleaning tank is located at the center of the bottom, and the input port of the connecting channel is set at the lowest point of the second cleaning tank; when the cleaning equipment is docked with the cleaning base, the rotation center of the second cleaning member is located above the center of the bottom of the second cleaning tank.

[0051] Optionally, the second cleaning member includes a rag and a tray, the rag is mounted on the tray and is in a circular ring shape; when the cleaning device is docked with the cleaning base, the inner ring area of ​​the rag is located directly above the input port of the connecting channel, and the wiper spans the ring width of the rag.

[0052] Optionally, the cleaning base further includes a base water pump, the second cleaning tank is provided with a spraying member, the base water pump is connected to the spraying member, the spraying member includes a first water spraying member and a second water spraying member, the first water spraying member is used to spray upward to wet the second cleaning member, and the second water spraying member is used to spray toward or along the tank bottom to rinse the second cleaning tank;

[0053] The base water pump supplies water to the injection member by being connected to a base station water tank provided on the cleaning base, or the base water pump supplies water to the injection member by being connected to an external water source.

[0054] In a fourth aspect, an embodiment of the present application provides a cleaning system, which includes a cleaning device and a cleaning base as described above, wherein the cleaning base is used to supply power to the cleaning device and / or clean the cleaning device.

[0055] Optionally, the cleaning device is provided with a floor brush assembly and a body assembly, the floor brush assembly being rotatably connected to the body assembly, and the floor brush assembly includes:

[0056] case;

[0057] A roller brush assembly is provided on the housing, the roller brush assembly comprising a first cleaning member for cleaning the surface to be cleaned along a direction of travel;

[0058] The side brush mechanism provided on the housing includes a first drive assembly and a side brush member, the side brush member being the second cleaning member, the first drive assembly being provided on the housing, the first drive assembly being used to drive the side brush member to swing, the bottom of the housing being provided with a receiving portion for receiving the side brush member, the receiving portion being provided with a side opening for at least partially passing the side brush member, the side opening being located on the outer side wall of the housing;

[0059] The side brush member is located at the rear side of the roller brush assembly in the direction of travel, and has at least a storage position and an exposed position, wherein the side brush member is retracted into the accommodating portion when in the storage position, and at least partially exposed from the side opening when in the exposed position.

[0060] In this way, the side brushes can clean corners and low spaces.

[0061] In a fifth aspect, an embodiment of the present application provides a cleaning control method for controlling the cleaning system as described above, wherein the cleaning system has a first water supply pipeline for supplying water to the first cleaning element and a second water supply pipeline for supplying water to the second cleaning element, the cleaning control method comprising:

[0062] Detecting whether the cleaning device is docked with the cleaning base, and after docking, controlling the cleaning system to enter a cleaning mode;

[0063] In cleaning mode, the cleaning system's negative pressure assembly is activated to generate suction at the suction port, the first and second cleaning components are rotated relative to the cleaning base, and the first water supply line is controlled to supply water to the first cleaning component and the second water supply line to the second cleaning component. The second water supply line eventually stops supplying water, and after a certain interval, the first water supply line eventually stops supplying water. It should be noted that water may be supplied intermittently multiple times in cleaning mode, and the final cessation of water supply refers to the time point when the corresponding water supply line ends its last water supply in that cleaning mode.

[0064] Since the first cleaning tank is located downstream of the sewage discharge of the second cleaning tank, the first cleaning tank is easily affected by the sewage discharge of the second cleaning tank. If the cleaning in the first cleaning tank stops, the second cleaning tank is still cleaning, there is a risk that the sewage discharged from the second cleaning tank will overflow into the first cleaning tank along the connecting pipe, which can easily cause the first cleaning parts that have been cleaned to be re-contaminated. In order to avoid this risk, the present application strictly controls the sewage discharge time of the two cleaning tanks through the water supply time of the water supply pipeline, so that the cleaning work in the first cleaning tank will stop after the cleaning work in the second cleaning tank stops, thereby avoiding the problem of repeated contamination.

[0065] Optionally, the cleaning control method further includes: after the cleaning mode is completed, controlling the cleaning system to enter a drying mode;

[0066] In the drying mode, the air outlet corresponding to the second cleaning tank is controlled to blow air, and at the same time, the negative pressure component of the cleaning system is controlled to start so that the suction port generates suction to increase the wind pressure in the connecting channel, so that the accumulated water in the connecting channel can be carried out to the suction port with the airflow for recovery.

[0067] In this way, the wind pressure generated by the air outlet and the wind pressure generated by the sewage suction port are used at the same time to perform a superimposed effect, thereby quickly accelerating the drying of the cleaning parts and the cleaning tank, avoiding the odor caused by bacterial growth, and bringing a better user experience.

[0068] Optionally, the air supply assembly of the cleaning base can selectively supply air to the first cleaning tank and the second cleaning tank individually or simultaneously;

[0069] In the drying mode, the air supply component is first controlled to supply air only to the second cleaning tank for a first period of time, and then the air supply component is controlled to supply air to both the first cleaning tank and the second cleaning tank.

[0070] When the power of the air supply component is constant, the wind pressure generated by blowing air into only one cleaning tank is generally greater than the wind pressure generated by blowing air into two cleaning tanks at the same time. By utilizing the larger wind pressure generated by blowing air alone, the ability to discharge accumulated water in the connecting channel can be further improved, thereby reducing the drying time in the connecting channel.

[0071] Optionally, the cleaning device further comprises a lifting assembly for adjusting the lifting of the second cleaning member;

[0072] The cleaning control method further comprises:

[0073] In the cleaning mode, the lifting assembly drives the second cleaning member to extend into the second cleaning tank, and causes the wiper of the second cleaning tank to come into interference contact with the second cleaning member;

[0074] In the drying mode, the lifting assembly drives the second cleaning member to separate from the wiper and controls the air outlet corresponding to the second cleaning tank to blow air.

[0075] In this way, the lifting assembly drives the second cleaning member to contact the wiper of the second cleaning tank and achieve an interference fit. The lifting assembly can provide downward pressure on the second cleaning member to enhance the scraping and cleaning effect of the wiper, and can also reduce the distance between the second cleaning member and the nozzle, improving the water spray cleaning effect. It should be noted that the air outlet is easily blocked by the side of the second cleaning member. In addition, after cleaning is completed, the second cleaning member can be adjusted to separate from the wiper. At this time, the air outlet is between the second cleaning member and the bottom of the second cleaning tank, leaving sufficient exhaust space for the air outlet, preventing the second cleaning member from being wetted by the bottom surface again, and can also enhance the drying convection effect.

[0076] In a sixth aspect, an embodiment of the present application provides a cleaning control method for controlling the above-mentioned cleaning system, wherein the cleaning device further includes a lifting assembly for adjusting the lifting of the second cleaning member, and the cleaning control method includes:

[0077] In the cleaning mode, the lifting assembly drives the second cleaning member to extend into the second cleaning tank, and causes the wiper of the second cleaning tank to come into interference contact with the second cleaning member; after the cleaning mode is completed, the cleaning system is controlled to enter the drying mode; the cleaning control method further includes:

[0078] In the drying mode, the lifting assembly drives the second cleaning member to separate from the wiper and controls the air outlet corresponding to the second cleaning tank to blow air.

[0079] In the present application, when the power of the air supply component is constant, the wind pressure generated by blowing air into only one cleaning tank is generally greater than the wind pressure generated by blowing air into two cleaning tanks at the same time. By utilizing the larger wind pressure generated by blowing air alone, the ability to discharge accumulated water in the connecting channel can be further improved, thereby reducing the drying time in the connecting channel.

Those skilled in the art will understand the specific meanings of these terms in this specification based on the specific circumstances.

[0114] With the rapid development and upgrade of smart home technologies, centered around floor scrubbers, floor scrubbers have become a standard feature in countless households. Floor scrubbers are intelligent cleaning devices that combine vacuuming, mopping, and self-cleaning functions, primarily driven by a motor for efficient floor cleaning. The base station associated with the floor scrubber primarily handles extended functions such as charging, water replenishment, wastewater removal, and self-cleaning. The two work together to enhance the user experience.

[0115] During specific use, the roller brush of the floor scrubber can rotate at high speed relative to the ground. The outer side of the roller brush can be covered with a material similar to soft velvet fabric. The soft velvet fabric is responsible for rubbing against the ground to clean the ground and gaps. The floor brush is also equipped with a silicone scraper on the back of the roller brush to scrape off water stains on the ground to improve the sewage recovery rate. During the operation of the roller brush, the floor scrubber can also replenish water to the roller brush through the built-in electric water pump, so that the roller brush can wet clean the ground. In addition, the user can push the floor scrubber forward when in use. At this time, the roller brush rotates and the scraper can scrape up the sewage on the ground. The negative pressure motor of the floor scrubber body generates a negative pressure at the sewage suction port and cooperates with the centrifugal force of the roller brush rotation to allow the stains to quickly enter the sewage suction port. In this way, after starting the floor scrubber, the user can push the floor scrubber in the predetermined direction to clean the ground.

[0116] Furthermore, after the floor scrubber finishes cleaning the floor, the base station can deep clean the roller brush to prevent odor and bacterial growth. During this process, the floor scrubber needs to be docked with the base station so that the roller brush can be placed in the cleaning tank. The roller brush starts to rotate relative to the cleaning tank. At this time, the built-in wiper of the floor brush can be used to interference fit with the roller brush. The floor scrubber's own water replenishment device replenishes water to the roller brush. The wiper can squeeze out the wastewater from the roller brush, thereby achieving self-cleaning of the roller brush. The wastewater washed out by the roller brush can be sucked away through the floor scrubber's own sewage suction port or through the sewage suction port of the base station to ensure a clean cycle.

[0117] However, in the related art, due to the physical constraints of the roller brush support structure (usually there is a 2-3mm thick end connecting partition), the device cannot achieve true zero-distance edge cleaning. This design flaw makes it difficult to completely remove dust accumulation in key areas such as corners and skirting edges, forming stubborn cleaning dead corners. Even if the user repeatedly pushes and pulls the device, dust or liquid stains may still remain, seriously restricting the comprehensiveness of the cleaning efficiency. Especially when dealing with the space at the bottom of low furniture, the thickness limitation of the existing roller brush system further amplifies the problem of cleaning blind spots. The roller brush at least cannot extend into a low space lower than its diameter, which directly affects the user's actual usage experience.

[0118] Therefore, a side brush can be added to the roller brush. The side brush can be used to clean one side of the floor scrubber specifically to clean corners, skirtings, and other edge locations, or the low spaces under some furniture, thereby eliminating blind spots as much as possible and avoiding repeated cleaning by users. However, after the additional side brush mechanism is finished cleaning the floor, the base station needs to clean the side brush to keep it clean and tidy, thus realizing the self-cleaning ability of the floor scrubber.

[0119] Therefore, it is necessary to provide a technical solution that can clean the roller brush and side brushes at the same time through the base station after the floor scrubber is placed on the base station, thereby realizing the self-cleaning function of the floor scrubber and reducing the tediousness of the user's operation.

[0120] See also Figures 1 to 6 . In an embodiment of the present application, the cleaning device 40 is provided with a floor brush assembly 44 and a body assembly 45, and the floor brush assembly 44 is arranged on the body assembly 45. The floor brush assembly 44 includes: a shell 10, a roller brush assembly 20 and a side brush mechanism 30. The roller brush assembly 20 is arranged on the shell 10, and the roller brush assembly 20 includes a first cleaning member 41, which is used to clean the surface to be cleaned along the direction of travel; the side brush mechanism 30 is arranged on the shell 10, and the side brush mechanism 30 includes a first driving assembly 31 and a side brush member 32. The first driving assembly 31 is arranged on the shell 10, and the first driving assembly 31 is used to drive the side brush member 32 to swing. The bottom of the shell 10 is provided with a accommodating portion 11 for accommodating the side brush member 32. It should be noted that the accommodating portion 11 refers to an open accommodating space; the accommodating portion 11 is provided with a side opening 12 for at least partially passing through the side brush member 32, and the side opening 12 is located on the outer wall of the shell 10. The side brush member 32 is located at the rear side of the roller brush assembly 20 in the direction of travel, and has at least a storage position and an exposed position, wherein the side brush member 32 is retracted into the accommodating portion 11 when in the storage position, and at least partially exposed from the side opening 12 when in the exposed position.

[0121] Since the exposure is from the left or right side, the swing exposure method is easier to borrow the front and rear space of the accommodating portion 11 than the straight exposure method, and the left and right space distance requirements of the accommodating portion 11 are relatively low. The accommodating portion 11 needs to avoid other components in the floor brush assembly 44 and is easy to form an irregular shape. For example, the accommodating portion 11 may have a large space at one end and a relatively small space at the other end in the front and rear direction; in view of the shape of the accommodating portion 11, the space of the accommodating portion 11 can be fully utilized through the swing exposure method. Under the premise of not interfering with the accommodating portion 11, the side brush member 32 can reasonably plan its movement path in the form of swinging, such as adjusting the swing direction, angle and rotation center, etc., so as to increase its maximum exposure degree, thereby further reducing the cleaning blind spots in low spaces.

[0122] In this way, by arranging the side brush member 32 in the accommodating portion 11 of the floor brush assembly 44, the side brush member 32 is driven by the first driving assembly 31 to swing outward through the side opening 12 of the accommodating portion 11 to achieve cleaning of corners and low spaces.

[0123] It should be noted that in the embodiment of the present application, the manner in which the first drive assembly 31 drives the side brush 32 to move is not limited to meet different needs. In one embodiment, the first drive assembly 31 can drive the side brush 32 to perform translational motion to switch the side brush 32 between the stored position and the exposed position; in another embodiment, the first drive assembly 31 can drive the side brush 32 to perform swinging motion to switch the side brush 32 between the stored position and the exposed position.

[0124] In this embodiment, the surface to be cleaned refers to the surface that is in direct contact with and cleaned by the roller brush assembly 20 and / or the side brush member 32 of the floor brush assembly 44. In one embodiment, the floor brush assembly 44 is placed on the ground, and the surface to be cleaned can be the ground; in another embodiment, the floor brush assembly 44 is placed on the wall, and the surface to be cleaned can also be a glass wall. The surface to be cleaned can be any contact surface that needs to be cleaned, and the specific details are not limited here. When the floor brush assembly 44 cleans the contact surface, it mainly relies on the friction between the roller brush assembly 20 provided on the shell 10 and the contact surface when it rolls. At the same time, when the roller brush assembly 20 rolls, the floor brush assembly 44 is pushed or pulled to move back and forth to quickly clean the contact surface.

[0125] Specifically, a housing 11 for accommodating the side brush 32 is provided at the bottom of the housing 10. The housing 11 is provided with a side opening 12 through which the side brush 32 can at least partially pass. The side opening 12 is located on the outer wall of the housing 10. In this way, the side brush 32 can be freely transformed in shape through the cooperation of the side opening 12 and the housing 11. When cleaning the side, the side brush 32 can be extended from the housing 11 through the side opening 12 to reach an exposed position. After cleaning is completed, the side brush 32 can be retracted into the housing 11 through the side opening 12. When the side brush 32 is in the housing 11, the housing 10 can protect the components in the housing 11 from external impact. The side opening 12 is located on the side wall of the housing 10. When the user uses the floor brush assembly 44, the floor brush assembly 44 is often moved back and forth to prevent external debris or furniture from colliding with the side brush 32 through the side opening 12.

[0126] Furthermore, the first drive assembly 31 of the side brush mechanism 30 is disposed on the housing 10, facilitating the retraction of the side brush 32 into the housing 10 or its extension outside the housing 10 to clean the surface to be cleaned. When the side brush 32 is retracted into the housing 10, it can at least partially retract into the accommodating portion 11 at the bottom of the housing 10. In other words, the thickness of the side brush 32 is significantly less than the thickness of the housing 10 above the floor brush assembly 44, allowing the side brush 32 to be concealed within the bottom of the housing 10. Furthermore, a side opening 12 is defined on the outer sidewall of the housing 10, through which the side brush 32 can at least partially pass. The side opening 12 in the outer wall of the housing 10 allows the side brush member 32 to be at least partially retracted from the outside of the housing 10 into the accommodating portion 11 at the bottom of the housing 10. This allows the side brush member 32 to be located in the storage position when not in use, thereby concealing the side brush member 32 and improving the aesthetics of the floor brush assembly 44, making it look similar to a conventional floor brush assembly 44. Alternatively, the side opening 12 in the outer wall of the housing 10 allows the side brush member 32 to be at least partially extended from the accommodating portion 11 to the outside of the housing 10, allowing the side brush member 32 to operate in an exposed position. In this way, the thinner side brush member 32 can be used to clean corners and low spaces around furniture, reducing blind spots of the floor brush assembly 44 and improving cleaning efficiency.

[0127] In this embodiment, the side brush member 32 can move between a storage position and an exposed position relative to the housing 10 under the action of the first drive assembly 31. When the side brush member 32 is not working, it is in the storage position, and the roller brush assembly 20 of the floor brush assembly 44 can complete the cleaning work normally. When the side brush member 32 is in the exposed position, the side brush member 32 is swung outward relative to the housing 10 under the action of the first drive assembly 31, so that the side brush member 32 protrudes outside the housing 10, making it easier for the side brush member 32 to clean the corner edges and low spaces of furniture, such as the gap between cabinet doors that are almost touching the ground, thereby reducing cleaning blind spots and improving cleaning efficiency. Specifically, when the side brush member 32 is in the exposed position, the side brush member 32 can extend at least 3 mm relative to the side wall of the housing 10 to more comprehensively clean the corner edges and low spaces of furniture. For example, the distance that the side brush member 32 extends relative to the side wall of the shell 10 can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4.0mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, 5.0mm, 10mm, 15mm, 20mm, 25mm, 30mm, or 35mm; the distance that the side brush member 32 extends relative to the side wall of the shell 10 is limited by the central axis and its own size, and its preferred extension distance is 20-30mm, which is suitable for general door panels and panel thicknesses.

[0128] In some embodiments, to reduce interaction between the side brushes 32 and the roller brush assembly 20 during operation, the side brushes 32 are positioned behind the roller brush assembly 20 on the floor brush assembly 44. Furthermore, the side brushes 32 can extend laterally relative to the direction of travel, allowing the roller brush assembly 20 to clean corners and low spaces around furniture as it travels along them. This allows the roller brush assembly 20 to clean the bulk of the floor while the side brushes 32 simultaneously clean residual areas around edges and corners, creating a complementary cleaning effect that ensures efficient cleaning.

[0129] Specifically, the different working states of the floor brush assembly 44 can be switched according to different cleaning needs. When encountering the corner edges of the wall and the low space of the furniture that the roller brush assembly 20 cannot clean, the side brush member 32 located in the storage position can be swung toward the front and outer sides of the floor brush assembly 44 to reach the exposed position, so that the side brush member 32 can protrude outside the shell 10 to form a wider cleaning area. It effectively covers the corner edges of the wall and the low space of the furniture that the roller brush assembly 20 cannot reach, reduces the cleaning blind spots, and improves the cleaning efficiency. After cleaning is completed, the side brush member 32 located in the exposed position can be swung toward the rear inner side of the floor brush assembly 44 to reach the storage position, while reducing the overall width of the floor brush assembly 44 to ensure the flexibility of cleaning.

[0130] Furthermore, after the cleaning device 40 completes cleaning the floor, the cleaning device 40 can be docked with the cleaning base 100, so that the cleaning base 100 can charge the cleaning device 40 and clean the roller brush assembly 20 and the side brush mechanism 30, thereby ensuring that the roller brush assembly 20 and the side brush mechanism 30 are clean and tidy. It is understood that the side brush member 32 can only be docked with the cleaning base 100 after it is in the storage position, so as to ensure that the side brush member 32 can be located in the corresponding cleaning position of the cleaning base 100.

[0131] In this embodiment, the specific shape of the side brush 32 is not limited to meet different needs. For example, the side brush 32 can be a circular disc, a triangular disc, or a rectangular disc. The shape of the cleaning slot on the cleaning base 100 corresponding to the side brush 32 also varies depending on the side brush 32. The following description assumes that the side brush 32 is a circular disc.

[0132] In some embodiments, the second drive member 312 of the side brush mechanism 30 can also be used to drive the side brush 32 to eccentrically rotate. Thus, when the swing position of the intermediate connector 314 is restricted and the intermediate connector 314 cannot move further outward, the cleaning range of the side brush 32, which moves synchronously with the intermediate connector 314, is limited. Eccentric rotation can increase the exposed area of ​​the side brush 32, making the cleaning range of the side brush 32 larger than the area of ​​the side brush 32 itself. This allows the floor brush assembly 44 to have a compact structure while also providing a large cleanable area. In this case, the size of the cleaning slot corresponding to the cleaning base 100 of this embodiment can be larger than that of the side brush 32 to ensure that the side brush 32 can eccentrically rotate within the cleaning slot to achieve self-cleaning of the side brush 32.

[0133] In this embodiment, the housing 10 may be provided with only one side brush mechanism 30, located on either the left or right side of the housing 10; or, alternatively, side brush mechanisms 30 may be provided on both the left and right sides of the housing 10. This embodiment does not limit the specific number and left and right positions of the side brush mechanisms 30; it is sufficient that the cleaning slots of the cleaning base 100 are provided accordingly to meet various requirements.

[0134] For example, the side brush mechanism 30 can be disposed on the right side of the housing 10. Thus, the accommodating portion 11 is disposed on the right side of the housing 10, with the side opening 12 of the right accommodating portion 11 facing the right outer wall of the housing 10, facilitating the entry and exit of the right side brush 32 into and out of the accommodating portion 11. In this manner, the first drive assembly 31 can drive the side brush 32 to rotate counterclockwise (e.g., from the six o'clock position to the three o'clock position), causing the side brush 32 to swing toward the right front side to reach an exposed position. The first drive assembly 31 can also drive the side brush 32 to rotate clockwise (e.g., from the three o'clock position to the six o'clock position), causing the side brush 32, which is in the exposed position, to swing toward the left rear side to reach a stowed position.

[0135] In some embodiments, the side brush member 32 faces the surface to be cleaned, and the first drive assembly 31 can drive the side brush member 32 to swing. The side brush member 32 swings toward the front of the floor brush assembly 44 to reach an exposed position, and the side brush member 32 swings toward the rear of the floor brush assembly 44 to reach a storage position.

[0136] In this way, the side brush member 32 can be swung in different directions to switch between different working states. The side brush member 32 can always clean the surface to be cleaned by facing the surface to be cleaned.

[0137] Specifically, the different working states of the floor brush assembly 44 can be switched according to different cleaning needs. When encountering the corner edges of the wall and the low space of the furniture that the roller brush assembly 20 cannot clean, the side brush member 32 located in the storage position can be swung toward the front and outer sides of the floor brush assembly 44 to reach the exposed position, so that the side brush member 32 can protrude outside the shell 10 to form a wider cleaning area. It effectively covers the corner edges of the wall and the low space of the furniture that the roller brush assembly 20 cannot reach, reduces the cleaning blind spots, and improves the cleaning efficiency. After cleaning is completed, the side brush member 32 located in the exposed position can be swung toward the rear inner side of the floor brush assembly 44 to reach the storage position, while reducing the overall width of the floor brush assembly 44 to ensure the flexibility of cleaning.

[0138] Furthermore, the floor brush assembly 44 mainly moves forward during cleaning. When the side brush member 32 extends outward and forward to work in the exposed position, the forward-moving floor brush assembly 44 drives the side brush member 32 forward. If there is a protrusion at the edge of the surface to be cleaned at this time, the side brush member 32 has space to retract backward, so that it can be forced to retract backward after hitting the protrusion. In this way, the side brush member 32 swings toward the front of the floor brush assembly 44 to reach the exposed position, and the side brush member 32 swings toward the rear of the floor brush assembly 44 to reach the storage position. This arrangement can leave space for the side brush member 32 to retract backward, preventing the side brush member 32 from getting stuck and damaging the side brush member 32. At the same time, when the floor brush assembly 44 moves forward, it will apply a backward friction force to the side brush member 32, so that after the side brush member 32 completes its work, the backward friction force can help the side brush member 32 swing back to the storage position, reducing the failure rate.

[0139] Of course, in other embodiments, the side brush member 32 is swung toward the rear of the floor brush assembly 44 to be an exposed position, and the side brush member 32 is swung toward the front of the floor brush assembly 44 to be a stored position.

[0140] In some embodiments, the side brush 32 faces the surface to be cleaned, and the first drive assembly 31 can drive the side brush 32 to move linearly, so that the side brush 32 moves toward the side opening 12 to reach an exposed position, and the side brush 32 moves away from the side opening 12 to reach a storage position.

[0141] In this way, the side brush member 32 can switch between different working states through linear movement, and has a simple structure and a fast response speed.

[0142] Specifically, the different working states of the floor brush assembly 44 can be switched according to different cleaning needs. When encountering the corner edges of walls and the low space of furniture that the roller brush assembly 20 cannot clean, the side brush member 32 located in the storage position can be moved to the left or right side of the floor brush assembly 44 to reach an exposed position, so that the side brush member 32 can protrude outside the shell 10 to form a wider cleaning area. It effectively covers the corner edges of walls and the low space of furniture that the roller brush assembly 20 cannot reach, reduces the cleaning blind spots, and improves the cleaning efficiency. After cleaning is completed, the side brush member 32 located in the exposed position can be swung toward the rear inner side of the floor brush assembly 44 to reach the storage position, while reducing the overall width of the floor brush assembly 44 to ensure the flexibility of cleaning.

[0143] In some embodiments, the side opening 12 is located on the right / left outer wall and the rear outer wall of the shell 10, and the side brush member 32 is close to the rear outer wall of the shell 10 when in the storage position, and spans the right / left outer wall of the shell 10 when in the exposed position.

[0144] Thus, when viewed from above, the side opening 12 is located at the lower left or lower right of the housing 10, and the side brush 32 can extend from the left rear side to the left, or from the right rear side to the right. Thus, when using the floor brush assembly 44, the floor brush assembly 44 is often moved back and forth to prevent external debris or furniture from colliding with the side brush 32 through the side opening 12.

[0145] Specifically, the side opening 12 can occupy part of the space of the rear outer side wall, so that the side brush 32 has more space when moving between the storage position and the exposed position, thereby preventing the side wall or rear wall of the housing 10 from interfering with the movement of the side brush 32. For example, when the side brush 32 swings relative to the housing 10, the side opening space of the rear outer side wall can provide more rotation space for the side brush 32, ensuring that the side brush 32 can extend as far as possible to be exposed, thereby increasing the cleaning range of low spaces and reducing cleaning blind spots.

[0146] In this embodiment, the housing 10 may be provided with only one side brush mechanism 30, located on either the left or right side of the housing 10; or, alternatively, side brush mechanisms 30 may be provided on both the left and right sides of the housing 10. This embodiment does not limit the specific number and left and right positions of the side brush mechanisms 30; it is sufficient that the cleaning slots of the cleaning base 100 are provided accordingly to meet various requirements.

[0147] In some embodiments, the side brush 32 faces the surface to be cleaned, and the first drive assembly 31 can drive the side brush 32 to move linearly, so that the side brush 32 moves toward the side opening 12 to reach an exposed position, and the side brush 32 moves away from the side opening 12 to reach a storage position.

[0148] In this way, the side brush member 32 can switch between different working states through linear movement, and has a simple structure and a fast response speed.

[0149] Specifically, the different working states of the floor brush assembly 44 can be switched according to different cleaning needs. When encountering the corner edges of walls and the low space of furniture that the roller brush assembly 20 cannot clean, the side brush member 32 located in the storage position can be moved to the left or right side of the floor brush assembly 44 to reach an exposed position, so that the side brush member 32 can protrude outside the shell 10 to form a wider cleaning area. It effectively covers the corner edges of walls and the low space of furniture that the roller brush assembly 20 cannot reach, reduces the cleaning blind spots, and improves the cleaning efficiency. After cleaning is completed, the side brush member 32 located in the exposed position can be swung toward the rear inner side of the floor brush assembly 44 to reach the storage position, while reducing the overall width of the floor brush assembly 44 to ensure the flexibility of cleaning.

[0150] In some embodiments, the side opening 12 is located on the right / left outer wall and the rear outer wall of the shell 10, and the side brush member 32 is close to the rear outer wall of the shell 10 when in the storage position, and spans the right / left outer wall of the shell 10 when in the exposed position.

[0151] Thus, when viewed from above, the side opening 12 is located at the lower left or lower right of the housing 10, and the side brush 32 can extend from the left rear side to the left, or from the right rear side to the right. Thus, when using the floor brush assembly 44, the floor brush assembly 44 is often moved back and forth to prevent external debris or furniture from colliding with the side brush 32 through the side opening 12.

[0152] Specifically, the side opening 12 can occupy part of the space of the rear outer side wall, so that the side brush 32 has more space when moving between the storage position and the exposed position, thereby preventing the side wall or rear wall of the housing 10 from interfering with the movement of the side brush 32. For example, when the side brush 32 swings relative to the housing 10, the side opening space of the rear outer side wall can provide more rotation space for the side brush 32, ensuring that the side brush 32 can extend as far as possible to be exposed, thereby increasing the cleaning range of low spaces and reducing cleaning blind spots.

[0153] In addition, it is understood that in the embodiment of the present application, without further explanation, the left, right, front and back are judged by looking down at the floor brush assembly 44. For example, please combine Figure 6 The roller brush assembly 20 is located at the front side, and the side brush mechanism 30 is located at the right rear side.

[0154] In this embodiment, the housing 10 may be provided with only one side brush mechanism 30, located on either the left or right side of the housing 10; or, alternatively, side brush mechanisms 30 may be provided on both the left and right sides of the housing 10. This embodiment does not limit the specific number and left and right positions of the side brush mechanisms 30; it is sufficient that the cleaning slots of the cleaning base 100 are provided accordingly to meet various requirements.

[0155] See also Figures 3 to 5 In some embodiments, the exposed position includes at least a first exposed position and a second exposed position. The side brush 32 reaches the second exposed position from the storage position via the first exposed position. The area of ​​the side brush 32 exposed from the side opening 12 in the second exposed position is greater than the area exposed from the side opening 12 in the first exposed position. Alternatively, the distance the side brush 32 is exposed from the side opening 12 in the second exposed position is greater than the distance it is exposed from the side opening 12 in the first exposed position.

[0156] In this way, the side brush 32 can have two outward swing amplitudes to meet different cleaning needs.

[0157] Specifically, the side brush 32 swings out from the storage position to the side and front. The side brush 32 first swings to the first exposed position. At this time, the side brush 32 can slightly protrude outside the housing 10, which is suitable for cleaning the edges of narrow aisle corners. If the cleaning space is relatively ample, or it is necessary to clean the low space of furniture, the side brush 32 can continue to swing from the first exposed position to the side and front to reach the second exposed position. In this way, the side brush 32 in the second exposed position protrudes further from the housing 10 than the side brush 32 in the first exposed position, so that the thinner side brush 32 has more exposed area, a larger side cleaning range, and a longer side cleaning distance, which is convenient for cleaning the low space of furniture. In this embodiment, the side brush 32 has two different degrees of outward swing to adapt to different cleaning needs.

[0158] See also Figure 4 and Figure 5 In some embodiments, the side brush member 32 is closer to the front end of the side opening 12 in the second exposed position than in the first exposed position.

[0159] In this way, the two swing amplitudes of the side brush member 32 can adapt to different cleaning needs. At the same time, the first exposed position is close to the rear end of the side opening 12, and the second exposed position is close to the front end of the side opening 12, which can be conducive to fully swinging and moving more smoothly.

[0160] In this embodiment, the side brush 32 can swing forward from its stored position within the housing 11 to an exposed position, and the swing sequence is from the stored position to the first exposed position, and then to the second exposed position. This allows the second exposed position to be positioned further forward than the first exposed position, meaning that the second exposed position is closer to the front end of the side opening 12, while the first exposed position is closer to the rear end of the side opening 12 of the housing 11. Thus, the two different swinging degrees of the side brush 32 can accommodate different cleaning needs.

[0161] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, the first drive assembly 31 includes a first drive member 311, a swing arm member 313, and an intermediate connecting member 314. The first drive member 311 is used to drive the swing arm member 313 to rotate. The swing arm member 313 is connected to the side brush member 32 through the intermediate connecting member 314. The intermediate connecting member 314 and the side brush member 32 swing synchronously. The accommodating portion 11 is provided with an avoidance hole 13 for avoiding the movement of the intermediate connecting member 314. The intermediate connecting member 314 passes through the avoidance hole 13.

[0162] In this way, the first driving member 311 can drive the side brush member 32 to swing between different positions. At the same time, the avoidance hole 13 facilitates the side brush member 32 to retract or swing out of the accommodation portion 11.

[0163] Specifically, among the first drive member 311, swing arm 313, intermediate connector 314, and side brush 32 of this embodiment, the first drive member 311, serving as a power source, is directly connected to the swing arm 313, driving the swing arm 313 to rotate about the rotation axis of the first drive member 311. The swing arm 313 indirectly transmits power to the side brush 32 via the intermediate connector 314, ultimately driving the side brush 32 to swing between a stowed position and an exposed position, ensuring the continuity and stability of power transmission from the first drive member 311. Simultaneously, the intermediate connector 314 swings synchronously with the side brush 32.

[0164] Furthermore, please combine Figures 3 to 5 Because the intermediate connector 314 and the side brushes 32 swing in sync, and the side brushes 32 swing between the stored and exposed positions, the accommodating portion 11 needs to be provided with a clearance hole 13 to allow the intermediate connector 314 to move in sync with the side brushes 32. This allows the intermediate connector 314 to pass through the clearance hole 13 without getting caught in the housing 10, allowing it to smoothly enter and exit the accommodating portion 11 along with the side brushes 32, allowing the side brushes 32 to swing between the stored and exposed positions.

[0165] See also Figure 1 、 Figure 2 and Figure 7In some embodiments, the swing trajectory of the side brush member 32 is an arc, and the avoidance hole 13 is an arc-shaped hole corresponding to the arc.

[0166] In this way, the intermediate connecting member 314 can pass through the avoidance hole 13 and smoothly enter and exit the accommodating portion 11 together with the side brush member 32.

[0167] In this embodiment, the first drive member 311, serving as a power source, is directly connected to the swing arm 313, driving the swing arm 313 to rotate about the first drive member 311's axis, indirectly transmitting power to the intermediate connector 314, causing the intermediate connector 314 to also rotate about the axis of the first drive member 311. Consequently, the intermediate connector 314 swings along an arcuate path. Simultaneously, the side brushes 32, which swing synchronously with the intermediate connector 314, also swing along an arcuate path. Because the side brushes 32 and the intermediate connector 314 are interconnected and swing synchronously, they enter and exit the accommodating portion 11 together. Therefore, the clearance hole 13 provided in the accommodating portion 11 for the intermediate connector 314 must conform to the swing path of the intermediate connector 314. In other words, the clearance hole 13 should be an arcuate hole corresponding to the swing arc of the intermediate connector 314. This prevents the intermediate connecting member 314 from being stuck in the accommodating portion 11 or generating unnecessary friction, and facilitates the intermediate connecting member 314 and the side brush member 32 to smoothly enter and exit the accommodating portion 11 .

[0168] See also Figure 1 and Figure 7 In some embodiments, the avoidance hole 13 extends to the side opening 12; or, the distance between the avoidance hole 13 and the side opening 12 is less than 5 mm; or, the avoidance hole 13 is connected to the side opening 12, and the side opening 12 can also allow the intermediate connector 314 to at least partially pass through.

[0169] In this way, the swing amplitude of the intermediate connecting member 314 and the side brush member 32 can be limited by the arrangement of the avoidance hole 13 of the accommodating portion 11 , so as to provide an exposed distance of the side brush member 32 .

[0170] Specifically, the length of the avoidance hole 13 can limit the swing position and amplitude of the intermediate connector 314, and the intermediate connector 314 swings synchronously with the side brush 32. In other words, the intermediate connector 314 can limit the swing position and amplitude of the side brush 32. When the avoidance hole 13 extends to the side opening 12, the intermediate connector 314 and the side brush 32 can have a larger swing range, allowing the side brush 32 to be closer to the front when exposed and further protrude from the housing 10, thus providing the side brush mechanism 30 with a larger cleaning range and improving cleaning efficiency.

[0171] Alternatively, the distance between the extension of the avoidance hole 13 and the side opening 12 is less than 5 mm. In this way, while limiting the position of the intermediate connector 314, the swing range of the intermediate connector 314 is maximized. For example, the distance between the extension of the avoidance hole 13 and the side opening 12 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, etc. This allows the maximum swing amplitude of the intermediate connector 314 and the side brush member 32 to be limited by precisely controlling the extension position of the avoidance hole 13, thereby producing floor brush assemblies 44 with different spacing distances according to different cleaning requirements. At the same time, it can also prevent the intermediate connector 314 and the side brush member 32 from swinging too far outward, making it difficult to reset, thereby increasing the operating stability and reliability of the equipment.

[0172] In the embodiment of the present application, there is no limitation on the spacing distance between the avoidance hole 13 and the side opening 12 to meet various requirements.

[0173] See also Figure 3 、 Figure 5 and Figure 7 In some embodiments, when the intermediate connector 314 moves to the end of the avoidance hole 13 close to the side opening 12, the side brush 32 simultaneously moves to the front end of the side opening 12; and / or when the intermediate connector 314 moves to the end of the avoidance hole 13 away from the side opening 12, the side brush 32 simultaneously moves to the storage position.

[0174] In this way, the intermediate connecting member 314 and the side brush member 32 are ensured to swing synchronously.

[0175] Specifically, because the intermediate connector 314 and the side brush 32 must swing synchronously, when the side brush 32 swings from the stored position to the exposed position, the intermediate connector 314 and the side brush 32 swing synchronously toward the side and front of the floor brush assembly 44. At this time, the intermediate connector 314 moves to the end of the avoidance hole 13 near the side opening 12 (i.e., swings toward the outside of the floor brush assembly 44), while the side brush 32 simultaneously moves to the front end of the side opening 12. Conversely, when the side brush 32 swings from the exposed position to the stored position, the intermediate connector 314 and the side brush 32 swing synchronously toward the inner and rearward sides of the floor brush assembly 44. At this time, the intermediate connector 314 moves to the end of the avoidance hole 13 away from the side opening 12 (i.e., swings toward the inner and rearward sides of the floor brush assembly 44), while the side brush 32 simultaneously moves to the rear end of the side opening 12.

[0176] See also Figure 2 and Figure 8In some embodiments, a second driving member 312 is provided on the intermediate connecting member 314, and the second driving member 312 is used to drive the side brush member 32 to move up and down and / or rotate; the second driving member 312 passes through the avoidance hole 13 and swings synchronously with the side brush member 32, or the second driving member 312 is integrated with the intermediate connecting member 314.

[0177] In this way, the second driving member 312 can drive the side brush member 32 to be close to the surface to be cleaned, or drive the side brush member 32 to rotate to clean the surface to be cleaned, thereby increasing the cleaning ability of the side brush member 32.

[0178] In this embodiment, the floor brush assembly 44 is further provided with a second driving member 312, which is disposed on the intermediate connecting member 314 and swings synchronously with the intermediate connecting member 314 and the side brush members 32. Thus, the second driving member 312 on the intermediate connecting member 314 also needs to enter and exit the accommodating portion 11. Therefore, like the intermediate connecting member 314, the second driving member 312 also needs to at least partially pass through the avoidance hole 13 in order to swing synchronously with the intermediate connecting member 314 and the side brush members 32. Simultaneously, the second driving member 312 can drive the side brush members 32 to move up and down. When enhanced cleaning is required, the side brush members 32 are driven to descend and press against the surface to be cleaned, thereby increasing the contact pressure between the side brush members 32 and the cleaning surface to enhance the cleaning effect. When avoiding obstacles or switching operating modes (for example, retracting the side brush members 32) is required, the second driving member 312 can drive the side brush members 32 to lift out of contact.

[0179] Furthermore, the second drive member 312 can also be used to drive the side brush member 32 to rotate, providing effective cleaning friction for the side brush member 32 during cleaning. At the same time, the exposed portion of the side brush member 32 protruding from the shell 10 can be used to clean the contact surface, while the other portion located inside the shell 10 is self-cleaning at the same time. In this way, after the exposed portion cleans the contact surface and becomes dirty, it can be rotated into the interior of the shell 10 for self-cleaning, keeping the side brush member 32 clean. After self-cleaning is completed, it rotates out to continue cleaning the contact surface, ensuring cleaning efficiency. It should be noted that cleaning the contact surface and self-cleaning are performed simultaneously when the side brush member 32 rotates.

[0180] In the embodiment of the present application, the driving mode of the second driving member 312 is not limited. For example, the second driving member 312 can be used to drive the side brush member 32 to perform lifting motion; or it can be used to drive the side brush member 32 to perform self-rotation motion; or it can drive the side brush member 32 to perform self-rotation motion, and at the same time drive the side brush member 32 to perform lifting motion, so as to meet various needs.

[0181] Furthermore, the second driving member 312 and the intermediate connecting member 314 can be integrated into one. The integrated design can reduce the assembly gap between the two components, improve the overall rigidity and movement accuracy of the components, simplify the installation steps, and make the floor brush assembly 44 work more stably.

[0182] See also Figure 2 and Figure 8 In some embodiments, the side brush member 32 is a circular disk, a triangular plate disk, or a rectangular disk. The side brush mechanism 30 further includes a second driving member 312 for driving the side brush member 32 to rotate eccentrically.

[0183] In this way, side brushes 32 of different shapes can meet different cleaning requirements.

[0184] Specifically, when the housing 10 is provided with only one side brush mechanism 30, the side brush member 32 of the side brush mechanism 30 can be a circular disc, a triangular plate disc, or a rectangular disc. When the side brush mechanisms 30 are provided on both the left and right sides of the housing 10, the side brush members 32 on the left and right sides can both be circular discs, triangular plate discs, or rectangular discs. Of course, the side brush members 32 on the left and right sides can also use discs of different shapes, for example, the side brush member 32 on the left side can use a circular disc, while the side brush member 32 on the right side can use a triangular plate disc or a rectangular disc; or the side brush member 32 on the left side can use a triangular plate disc, while the side brush member 32 on the right side can use a circular disc or a rectangular disc; or the side brush member 32 on the left side can use a rectangular disc, while the side brush member 32 on the right side can use a circular disc or a triangular plate disc. The embodiment of the present application does not limit the specific shape of the side brush member 32 to meet various needs.

[0185] In addition, the second driving member 312 of the side brush mechanism 30 can also be used to drive the side brush member 32 to perform eccentric rotation. Thus, when the swing position of the intermediate connecting member 314 is limited and the intermediate connecting member 314 cannot move further outward, the cleaning range of the side brush member 32, which moves synchronously with the intermediate connecting member 314, is limited. The eccentric rotation can increase the exposed area of ​​the side brush member 32, making the cleaning range of the side brush member 32 larger than the area of ​​the side brush member 32 itself, so that the floor brush assembly 44 has a compact structure while also having a large cleaning area.

[0186] In some embodiments, the side brush member 32 is elastically connected to the intermediate connecting member 314, and the second driving member 312 can drive the side brush member 32 to descend, so that the side brush member 32 descends and elastically abuts against the surface to be cleaned.

[0187] In this way, the second driving member 312 can generate downward pressure on the side brush member 32, increasing the friction between the side brush member 32 and the surface to be cleaned, thereby ensuring a good cleaning effect. At the same time, the side brush member 32 is elastically connected to the intermediate connecting member 314, so that the side brush member 32 has a rebound range when it contacts an obstacle, preventing the side brush member 32 from being stuck and damaged by external pressure.

[0188] See also Figure 8 In some embodiments, an elastic member 315 is provided at the rotational connection between the first driving member 311 and the swing arm member 313. The elastic member 315 is used to provide the swing arm member 313 with a certain elastic rotation amount. When the side brush member 32 is externally squeezed in the exposed position, the side brush member 32 drives the swing arm member 313 to compress the elastic member 315 and can retract a part within the range of the elastic rotation amount of the swing arm member 313. When the side brush member 32 loses external squeezing, the swing arm member 313 drives the side brush member 32 to swing outward under the action of the rebound force of the elastic member 315.

[0189] In this way, the side brush member 32 can be prevented from getting stuck due to touching an obstacle in front during operation, and while ensuring work efficiency, the side brush member 32 can also be prevented from being damaged by external extrusion.

[0190] In this embodiment, when the side brush 32 moves forward within the floor-following brush assembly 44, if a raised obstacle appears in the path of the side brush 32, upon contact with the obstacle, the side brush 32 will hinder its forward movement, generating a backward force on the side brush 32. This force, in turn, drives the swing arm 313 through the side brush 32 to compress the elastic member 315, causing the swing arm 313 to rotate elastically to a certain extent, causing the side brush 32 to partially retract within the range of the swing arm 313's elastic rotation, thereby eliminating the force exerted by the obstacle on the side brush 32. Similarly, when the side brush 32 is externally squeezed in its exposed position, the side brush 32 drives the swing arm 313 to compress the elastic member 315, allowing it to partially retract within the range of the swing arm 313's elastic rotation. At the same time, when the side brush member 32 avoids obstacles or loses external pressure, the swing arm member 313 can drive the side brush member 32 to return to the exposed position under the action of the rebound force of the elastic member 315, so that the side brush member 32 continues to work.

[0191] In some embodiments, the elastic member 315 is a torsion spring, a rubber strip, or a spring.

[0192] In this way, different types of elastic members 315 can be selected to meet various elastic requirements.

[0193] In the embodiment of the present application, the specific type of the elastic member 315 is not limited, as long as the elastic member 315 can meet the elasticity requirements. For example, the elastic member 315 can be a torsion spring, a rubber strip, or a spring to meet various requirements.

[0194] See also Figures 1 to 3 In some embodiments, the housing 10 is provided with a rotatable guide wheel 14 , which is located on the outer side wall of the housing 10 near the side opening 12 .

[0195] In this way, when the floor brush assembly 44 is close to the wall and the side brush member 32 is used to clean the corner edge of the wall, the guide wheel 14 on the same side can resist the approaching wall and roll forward with the floor brush assembly 44, reducing the contact area and friction between the floor brush assembly 44 and the wall.

[0196] In this embodiment, when the floor brush assembly 44 is cleaning corner edges, the guide wheel 14 on the same side of the side brush member 32 can abut against the wall skirting, preventing the roller brush support structure on the side of the floor brush assembly 44 from directly contacting the wall skirting, effectively reducing the contact area between the floor brush assembly 44 and the wall skirting. At the same time, this can convert the sliding friction between the support structure and the wall skirting into rolling friction between the guide wheel 14 and the wall skirting, significantly reducing the running resistance of the floor brush assembly 44 when working against the wall.

[0197] It is understood that the number of guide wheels 14 located on the same side of the side brush member 32 is preferably two, so as to ensure the stability of the guide wheel 14 when it abuts against the wall skirting. However, in the embodiment of the present application, the specific number of guide wheels is not limited, for example, it can be one, two, three, etc. to meet various needs.

[0198] In addition, when the side brush mechanisms 30 are provided on both the left and right sides of the housing 10 , rotatable guide wheels 14 may also be provided on both the left and right sides of the housing 10 .

[0199] See also Figures 1 to 3 In some embodiments, the side opening 12 is flush with the outer side wall of the housing 10 , and the distance that the guide wheel 14 protrudes from the outer side wall is less than or equal to the distance that the side brush member 32 is exposed from the side opening 12 .

[0200] In this way, the guide wheel 14 reduces the running resistance of the floor brush assembly 44 while avoiding affecting the operation of the side brush members 32, thereby ensuring cleaning efficiency.

[0201] In this embodiment, the side opening 12 of the accommodating portion 11 is flush with the outer wall of the housing 10, making the floor brush assembly 44 more compact and the appearance lines smoother, while avoiding the impact of unnecessary protrusions of the housing 10 on cleaning corner edges. At the same time, the guide wheel 14 on the same side as the side opening 12 protrudes to the outer wall of the housing 10, ensuring that when the floor brush assembly 44 performs the corner edge cleaning operation, the guide wheel 14 on the same side as the side brush member 32 can press against the wall skirting, reducing the friction when the floor brush assembly 44 contacts the wall. In addition, the distance that the guide wheel 14 protrudes from the outer wall is less than or equal to the distance that the side brush member 32 is exposed from the side opening 12. This can prevent the guide wheel 14 from excessively protruding against the wall and exceeding the cleaning range of the side brush member 32, ensuring that the side brush member 32 can efficiently clean the corner edges and low spaces of furniture.

[0202] See also Figures 1 to 5One embodiment of the present application provides a floor brush assembly 44, which includes: a housing 10, a roller brush assembly 20, a side brush mechanism 30, and a sewage suction pipe (not shown in the figure); the roller brush assembly 20 is arranged on the housing 10, and is used to clean the surface to be cleaned along the direction of travel; the sewage suction pipe is at least partially arranged in the housing 10 and extends toward the roller brush assembly 20; the side brush mechanism 30 is arranged on the housing 10, and the side brush mechanism 30 includes a side brush member 32 and a first drive assembly 31. The side brush member 32 is used to clean the surface to be cleaned, and the first drive assembly 31 is arranged on the housing 10. A receiving portion 11 is provided at the bottom of the housing 10, and the receiving portion 11 is used to receive the side brush member 32 and leave space for the side brush member 32 to move. The receiving portion 11 is located on one side of the sewage suction pipe and at the rear side of the roller brush assembly 20. The receiving portion 11 extends to the right / left outer wall and the rear outer wall of the housing 10. The first drive assembly 31 is used to drive the side brush member 32 to partially move out of the receiving portion 11 to be exposed outside the housing 10.

[0203] In this way, the accommodating portion 11 can be used as a placement space for the side brush member 32 . When not needed, the side brush member 32 can be retracted into the accommodating portion 11 , so that the housing 10 can protect the side brush member 32 .

[0204] In this embodiment, the accommodating portion 11 is located below the shell 10 and is a semi-enclosed cavity space (a groove-shaped space formed by retracting the shell 10 toward the inside of the shell 10), and the side brush member 32 can move freely inside the accommodating portion 11. The side brush member 32 can move up and down inside the accommodating portion 11, and the side brush member 32 can also be partially moved out of the accommodating portion 11 to be exposed outside the shell 10. Specifically, the accommodating portion 11 is located at the left rear or right rear of the floor brush assembly 44. At this time, the side brush member 32 can be moved out from the left rear or right rear of the floor brush assembly 44 (that is, moved out of the accommodating portion 11). In this way, the free movement of the side brush member 32 can be guaranteed without affecting the inherent position of the roller brush assembly 20 and the sewage suction pipe.

[0205] In some embodiments, the side brush 32 has at least a storage position and an exposed position, wherein the side brush 32 is retracted into the accommodating portion 11 when in the storage position, and at least partially protrudes from the outside of the shell 10 when in the exposed position.

[0206] In this way, the side brush member 32 can change different positions to achieve corresponding functions. When the side brush member 32 is in the storage position, it is retracted into the accommodating portion 11. At this time, the shell 10 can protect the side brush member 32; when the side brush member 32 is in the exposed position, at least part of it protrudes from the outside of the shell 10 to achieve cleaning of the side.

[0207] In some embodiments, the first drive assembly 31 can drive the side brush member 32 to swing, the side brush member 32 swings toward the front of the floor brush assembly 44 to reach an exposed position, and the side brush member 32 swings toward the rear of the floor brush assembly 44 to reach a storage position.

[0208] In this way, the first driving assembly 31 drives the side brush member 32 to swing, and the side brush member 32 can move freely between two positions without adding too many rotating structures, with fast response speed and wide cleaning range.

[0209] In some embodiments, the floor brush assembly 44 also includes a first auxiliary wheel 15, which is arranged in the middle of the rear end of the shell 10. The first auxiliary wheel 15 and the roller brush assembly 20 jointly support the shell 10 on the surface to be cleaned, so that the outer wall of the shell 10 maintains a certain gap with the surface to be cleaned, and the accommodating portion 11 is located on the left or right side of the first auxiliary wheel 15.

[0210] In this way, the first auxiliary wheel 15 and the roller brush assembly 20 work together to support the floor brush assembly 44, so that a certain gap is maintained between the outer wall of the shell 10 and the surface to be cleaned, ensuring smooth movement of the floor brush assembly 44 and improving cleaning efficiency.

[0211] In this embodiment, there can be two first auxiliary wheels 15, both of which are located in the middle of the rear end of the housing 10, forming at least three fulcrums to support the floor brush assembly 44. In one embodiment, when the accommodating portion 11 is on the left side, the first auxiliary wheel 15 near the left side is thinner to avoid the accommodating portion 11 and ensure that the side brush 32 has sufficient space to move out from the left side. In another embodiment, when the accommodating portion 11 is on the right side, the first auxiliary wheel 15 near the right side is thinner to avoid the accommodating portion 11 and ensure that the side brush 32 has sufficient space to move out from the right side.

[0212] In some embodiments, the accommodating portion 11 is provided with a side opening 12 for at least partially passing the side brush member 32 . The side opening 12 is located on the outer wall of the shell 10 and extends from the right / left outer wall of the shell 10 to the rear outer wall of the shell.

[0213] In this way, the side opening 12 occupies the right / left outer side wall and the rear outer side wall at the same time, so that the side brush member 32 has enough space to perform a swinging motion.

[0214] Specifically, the accommodating portion 11 cooperates with the side opening 12 to realize the free movement of the side brush member 32 , while leaving as much moving space as possible for the side brush member 32 , so that the side brush member 32 extends farther relative to the housing 10 .

[0215] See also Figures 1 to 5One embodiment of the present application provides a floor brush assembly 44 , which includes a housing 10 , a roller brush assembly 20 , a side brush mechanism 30 , and a first auxiliary wheel 15 . The roller brush assembly 20 is arranged on the shell 10, and is used to clean the surface to be cleaned along the direction of travel; the first auxiliary wheel 15 is arranged in the middle of the rear end of the shell 10, and the first auxiliary wheel 15 and the roller brush assembly 20 jointly support the shell 10 on the surface to be cleaned, so that the outer wall of the shell 10 maintains a certain gap with the surface to be cleaned; the side brush mechanism 30 is arranged on the shell 10, and the side brush mechanism 30 includes a first drive assembly 31 and a side brush member 32, the first drive assembly 31 is arranged on the shell 10, and the first drive assembly 31 is used to drive the side brush member 32 to move; the side brush member 32 is located on the rear side of the roller brush assembly 20 in the direction of travel, and it has at least a storage position and an exposed position, wherein the side brush member 32 is covered by the shell 10 when in the storage position, and is at least partially exposed to the outside of the shell 10 when in the exposed position; the shell 10 is provided with a side opening 12 on at least its left / right outer wall for partially exposing the side brush member 32.

[0216] Because the floor brush assembly 44 needs to be equipped with a supporting structure, a gap is formed between it and the side wall, and the problem of zero-distance edge contact cannot be achieved. In addition, during the cleaning process, some furniture will have low spaces, and the floor brush assembly 44 cannot extend into the low space, resulting in a cleaning blind spot. The side brush member 32 of the embodiment of the present application can move between the storage position and the exposed position through the side opening 12 under the action of the first drive assembly 31. When the side brush member 32 is in the storage position, the roller brush assembly 20 can achieve normal floor cleaning; when the side brush member 32 is in the exposed position, the side brush member 32 swings outward relative to the shell 10 under the action of the first drive assembly 31 to protrude outside the shell 10, so that the corner edges and low spaces of furniture can be cleaned, reducing cleaning blind spots and improving cleaning efficiency.

[0217] In some embodiments, the cleaning device 40 has at least a first cleaning mode and a second cleaning mode, the roller brush assembly 20 starts running in the first cleaning mode, and the side brush mechanism 30 stops running in the first cleaning mode; the roller brush assembly 20 and the side brush mechanism 30 both start running in the second cleaning mode; the side brush member 32 is in or returns to the storage position when it is stopped, and the side brush member 32 is in or reaches the exposed position when it is started.

[0218] In this way, the cleaning device 40 can achieve different functions through different cleaning modes. The user can also choose to enter the first cleaning mode, in which the roller brush assembly 20 cleans while the side brush mechanism 30 stops to save energy; the user can also choose to enter the second cleaning mode, in which the roller brush assembly 20 and the side brush mechanism 30 clean, and the side brush mechanism 30 can clean side corners or low spaces under furniture.

[0219] In some embodiments, the cleaning device 40 also includes a side detector (not shown in the figure) and a controller (not shown in the figure), the controller is electrically connected to the side detector and the side brush mechanism 30 respectively, the side detector is configured to detect that the distance between the side surface of the shell 10 close to the side brush member 32 and the external obstacle is less than a predetermined distance to output a side signal, and the controller is configured to control the side brush mechanism 30 to start operation when triggered by the side signal.

[0220] In this way, the controller can detect the relative position of the housing 10 and the side surface through the side detector to achieve automatic switching of the cleaning mode. Without user operation, the cleaning device 40 can automatically control whether to clean through the side brush mechanism 30.

[0221] See also Figures 10 to 18 . One embodiment of the present application provides a cleaning base 100 for docking a cleaning device 40. The cleaning base 100 includes a shell 50. The shell 50 is provided with a first cleaning slot 51 and a second cleaning slot 52. The first cleaning slot 51 is used to carry the first cleaning member 41 of the cleaning device 40, and the second cleaning slot 52 is used to carry the second cleaning member 42 of the cleaning device 40. The shell 50 is provided with a connecting channel 53. The input port 531 of the connecting channel 53 is connected to the second cleaning slot 52, and the output port 532 of the connecting channel 53 is located around or inside the first cleaning slot 51. When the cleaning device 40 is docked with the cleaning base 100, the sewage suction port 43 of the cleaning device 40 is located around or inside the first cleaning slot 51, so that the sewage suction port 43 can generate suction on the first cleaning slot 51 and the output port 532 of the connecting channel 53. It should be noted that the area around the first cleaning slot 51 includes but is not limited to the range within 5 cm from the edge of the first cleaning slot 51, and may also include the boundary range where the negative pressure of the airflow near the first cleaning slot 51 exceeds a predetermined limit.

[0222] At present, the cleaning device 40 generally has only one negative pressure suction component to form a sewage suction port 43. This easily leads to the situation that when two cleaning slots appear on the cleaning base 100, the cleaning device 40 is generally unable to suction the two cleaning slots at the same time. The sewage suction port 43 is close to the first cleaning slot 51 and can generate a large suction force on the first cleaning slot 51, but it is also relatively far away from the second cleaning slot 52, so that the suction force near the second cleaning slot 52 is insufficient to support the dirt in it to be extracted, thereby failing to achieve integrated cleaning. However, the present application, without adding a new negative pressure suction component in advance, connects the first cleaning slot 51 and the second cleaning slot 52 to each other through the connecting channel 53, so that the negative pressure suction generated by the sewage suction port at the first cleaning slot 51 can be transmitted to the second cleaning slot 52 through the connecting channel 53, and then the dirt in the second cleaning slot 52 can be sucked into the same sewage suction port 43 through the connecting channel 53, thereby achieving simultaneous suction processing of the dirt in the two cleaning slots.

[0223] In this way, the first cleaning tank 51 and the second cleaning tank 52 are connected to each other through the connecting channel 53, so that the negative pressure suction generated by the suction port 43 at the first cleaning tank 51 can be transmitted to the second cleaning tank 52 through the connecting channel 53, thereby realizing simultaneous treatment of dirt in the two cleaning tanks.

[0224] It should be noted that, in this embodiment, the first cleaning member 41 is the roller brush assembly 20 , and the second cleaning member 42 is the side brush member 32 .

[0225] In this embodiment, the cleaning base 100 can carry the cleaning device 40, facilitating the placement and charging of the cleaning device 40, and also providing a place for the cleaning device 40 to perform self-cleaning. Specifically, the first cleaning tank 51 is used to carry the first cleaning member 41 of the cleaning device 40, facilitating the first cleaning member 41 to perform cleaning within the first cleaning tank 51; the second cleaning tank 52 is used to carry the second cleaning member 42 of the cleaning device 40, facilitating the second cleaning member 42 to perform cleaning within the second cleaning tank 52.

[0226] Furthermore, in order to save costs and simplify the component structure, a single sewage suction port 43 can simultaneously serve the first cleaning member 41 and the second cleaning member 42. This embodiment provides a connecting channel 53 between the first cleaning tank 51 and the second cleaning tank 52, thereby interconnecting the two cleaning tanks. Furthermore, when the cleaning device 40 is docked with the cleaning base 100, the sewage suction port 43 of the cleaning device 40 can be located around or within the first cleaning tank 51, forming a relatively enclosed space within the first cleaning tank 51. In this way, while the sewage suction port 43 generates suction for the self-cleaning of the first cleaning member 41, it can also create a negative pressure suction within the first cleaning tank 51. Because the output port 532 of the connecting channel 53 is located around or within the first cleaning tank 51, the negative pressure suction within the first cleaning tank 51 can be transmitted to the output port 532 of the connecting channel 53. From there, it is transferred into the connecting channel 53, where it is then transmitted to the input port 531 of the connecting channel 53, where it is then transferred into the second cleaning tank 52. This allows dirt within the second cleaning tank 52 to pass through the second cleaning tank 52, to the input port 531, then to the connecting channel 53, and finally to the output port 82. Finally, it passes through the first cleaning tank 51 and is finally sucked away by the suction port 43. In this way, the suction port 43 can remove dirt generated by cleaning the second cleaning element 42 within the second cleaning tank 52. This allows a single suction port 43 to serve both the first cleaning element 41 and the second cleaning element 42, improving self-cleaning efficiency.

[0227] For example, after the user has finished cleaning the floor using the cleaning device 40, they can place the cleaning device 40 on the cleaning base 100 and activate the self-cleaning mode of the cleaning device 40. In self-cleaning mode, the roller brush assembly 20 and the side brush member 32 of the cleaning device 40 can rotate, and the fan of the cleaning device 40 is activated to generate negative pressure at the sewage suction port 43. The roller brush assembly 20 and the side brush member 32 complete the cleaning process in the first cleaning tank 51 and the second cleaning tank 52, respectively. After cleaning, sewage is generated. The sewage in the first cleaning tank 51 can be directly sucked into the sewage tank of the cleaning device 40 through the sewage suction port 43. The sewage in the second cleaning tank 52 can be sucked into the sewage tank of the cleaning device 40 through the sewage suction port 43 through the connecting channel 53, thereby completing the self-cleaning of the cleaning device 40.

[0228] See also Figure 13 and Figure 14 In some embodiments, the cleaning device 40 is provided with a floor brush assembly 44 and a body assembly 45, the floor brush assembly 44 is rotatably connected to the body assembly 45, the floor brush assembly 44 is provided with a floor scraping bar 441, the first cleaning member 41 is a roller brush, the floor scraping bar 441 maintains a certain gap with the first cleaning member 41, the sewage suction port 43 is arranged opposite to the first cleaning member 41, the floor scraping bar 441 extends to the periphery of the sewage suction port 43, so that the gap between the floor scraping bar 441 and the first cleaning member 41 can generate suction under the action of the sewage suction port 43; when the cleaning device 40 is docked with the cleaning base 100, the output port 532 of the connecting channel 53 is located in the gap between the floor scraping bar 441 and the first cleaning member 41, so that the output port 532 of the connecting channel 53 can generate suction.

[0229] In this way, the floor scraping strip 441 of the floor brush assembly 44 extends toward the sewage suction port 43 to form a diversion structure, which facilitates the transmission of the negative pressure generated by the sewage suction port 43 to the corresponding supporting surface along the extension direction of the floor scraping strip 441. The area with the relatively largest suction force on the supporting surface is between the floor scraping strip 441 and the first cleaning member 41. Adjusting the output port of the connecting channel 53 to this area can enable the connecting channel 53 to obtain greater suction force, thereby enhancing the sewage discharge capacity of the second cleaning tank 52.

[0230] Specifically, when the cleaning device 40 is cleaning the floor, the roller brush of the floor brush assembly 44 (i.e., the first cleaning component 41) begins to rotate under the body assembly 45, and scrapes up the dirt on the floor or rolls it backward, rolling the dirt to the floor scraping strip 441. The floor scraping strip 441 is in close contact with the floor, collecting the dirt and gathering it in the gap between the floor scraping strip 441 and the first cleaning component 41, and scraping off some of the dirt and moisture, exposing the dirt to the negative pressure suction formed by the suction port 43, making it easier to suck the dirt into the suction port 43 and clean the floor. At the same time, the floor scraping strip 441 in close contact with the floor can achieve a certain degree of sealing, reducing the leakage of negative pressure suction from the back side of the cleaning device 40. In this way, it not only ensures the effective removal of various floor stains, but also realizes the immediate recycling of garbage, significantly improving the cleaning efficiency.

[0231] Furthermore, a certain gap is maintained between the ground scraping strip 441 and the first cleaning member 41 to prevent the ground scraping strip 441 and the first cleaning member 41 from interfering with each other during operation. When the cleaning work on the ground is completed, the cleaning device 40 is placed back on the cleaning base 100 and docking is completed. At this time, the output port 532 of the connecting channel 53 is located in the gap between the ground scraping strip 441 and the first cleaning member 41. In this way, during self-cleaning, the negative pressure suction formed between the ground scraping strip 441 and the first cleaning member 41 in the first cleaning tank 51 can be transmitted to the output port 532 of the connecting channel 53, and transmitted into the connecting channel 53 through the output port 532, and then the negative pressure suction is transmitted to the input port 531 of the connecting channel 53 through the connecting channel 53, and then the negative pressure suction is transmitted to the second cleaning tank 52, so as to facilitate the suction of dirt generated by the second cleaning member 42 performing self-cleaning work in the second cleaning tank 52. Of course, the first cleaning member 41 and the first cleaning tank 51 closer to the sewage suction port 43 are subjected to greater suction force, and the cleaning effect is better. In this way, one sewage suction port 43 can serve two cleaning members and two cleaning tanks at the same time, thereby improving the self-cleaning efficiency.

[0232] See also Figure 13 and Figure 14 In some embodiments, the scraping bar 441 is provided with an escape portion 442, which is used to leave a transitional flow space for the fluid in the connecting channel 53 to flow toward the sewage suction port 43; when the cleaning device 40 and the cleaning base 100 are docked, the scraping bar 441 contacts the first cleaning tank 51 or the housing 50, and the escape portion 442 surrounds the outer periphery of the output port 532 of the connecting channel 53. The fluid output from the output port 532 of the connecting channel 53 enters the sewage suction port 43 through the escape portion 442.

[0233] Since the gap between the floor scraping strip 441 and the first cleaning member 41 is very small, it is generally larger than the size of the output port of the connecting channel 53, which easily leads to the output port not being completely covered by the gap, thereby weakening the suction force of the output port. Therefore, it is necessary to improve the floor scraping strip 441 to adapt to the corresponding output port without affecting the basic function of the floor scraping strip 441. In this solution, the floor scraping strip 441 makes room for the output port of the connecting channel 53 by setting an avoidance portion 442. The avoidance portion 442 is close to the output port, so that the sewage discharged from the output port 532 of the connecting channel 53 can enter the sewage suction port 43 through the avoidance portion 442.

[0234] In this embodiment, when the cleaning device 40 is docked with the cleaning base 100 and performs self-cleaning on the cleaning base 100, it is necessary to clean the first cleaning member 41 and the second cleaning member 42 simultaneously. At this time, the ground scraping strip 441 disposed opposite the first cleaning member 41 will come into contact with the first cleaning tank 51 or the housing 50. While ensuring airtightness between the first cleaning member 41 and the first cleaning tank 51, it can also easily block the output port 532 of the connecting channel 53, preventing the negative pressure suction generated by the suction port 43 from being transmitted through the connecting channel 53 to the second cleaning tank 52, thus affecting the cleaning of the second cleaning member 42. Therefore, in this embodiment, a relief portion 442 is provided on the ground scraping strip 441 to avoid the output port 532 of the connecting channel 53. This allows the output port 532 of the connecting channel 53 to be located between the first cleaning member 41 and the ground scraping strip 441 after docking. The relief portion 442 surrounds the outer periphery of the output port 532 of the connecting channel 53, ensuring airtightness and preventing the negative pressure suction force generated by the suction port 43 from leaking. This allows the suction force to be smoothly transferred to the second cleaning tank 52 through the relief portion 442 and the connecting channel 53, simultaneously removing dirt or sewage from the second cleaning member 42. This allows a single suction port 43 to simultaneously serve two cleaning members and two cleaning tanks, improving self-cleaning efficiency.

[0235] See also Figure 13 and Figure 14 In some embodiments, the sewage suction port 43 is located above the middle of the ground scraping strip 441, and the avoidance portion 442 is located in the middle of the ground scraping strip 441 and has a U-shaped structure. The avoidance portion 442 has the function of scraping water on the ground.

[0236] This allows the escape portion 442 to transfer the negative pressure from the suction port 43 to the connecting channel 53. It also provides a scraping function, without affecting cleaning efficiency. The suction force is greatest near the middle of the scraping strip 441. The escape portion 442 is located in the middle of the scraping strip 441 and has a U-shaped structure. This allows the scraping strip 441 to absorb dirt from both sides of the suction port 43 when cleaning the floor. The U-shaped structure creates more space between the suction port 43 and the connecting channel 53.

[0237] In this embodiment, because the sewage suction port 43 is located above the middle portion of the floor scraping strip 441, to ensure smooth transfer of suction force, the path from the sewage suction port 43 to the output port 532 of the connecting channel 53 should be shortened. Therefore, the avoidance portion 442 is located in the middle portion of the floor scraping strip 441. Furthermore, to ensure that the scraping performance of the floor scraping strip 441 is not affected, the avoidance portion 442 is configured in a U-shaped structure. This U-shaped structure allows dirt to more easily accumulate at the sewage suction port 43.

[0238] Specifically, the middle portion of the floor scraping strip 441 is protruded toward the rear of the cleaning device 40, forming a U-shaped relief portion 442 in front of the middle portion of the floor scraping strip 441 that is recessed to the rear. This allows the upper sewage suction port 43 to be located between the floor scraping strip 441 and the first cleaning member 41 through the recessed U-shaped structure. At the same time, when the device and the base are docked, the output port 532 of the connecting channel 53 can be located in front of the U-shaped relief portion 442. In other words, the projections of the output port 532 and the sewage suction port 43 on the ground partially overlap, and the output port 532 is located directly below the sewage suction port 43. This ensures that the suction force of the sewage suction port 43 can be smoothly transmitted to the connecting channel 53 while retaining the ground wiping ability of the relief portion 442 of the floor scraping strip 441, thereby ensuring the cleaning efficiency of the cleaning device 40. At the same time, the U-shaped structure of the avoidance portion 442 surrounds the outer peripheral side of the output port 532 of the connecting channel 53, ensuring good air tightness during sewage suction, ensuring the suction force of the sewage suction port 43 on sewage, and improving the self-cleaning efficiency.

[0239] See also Figure 15 and Figure 16 as well as Figure 19 In some embodiments, the first cleaning tank 51 and the second cleaning tank 52 are arranged on the housing 50 along the front-to-back direction of the cleaning base 100, the second cleaning tank 52 is arranged toward the left or right side of the housing 50, the input port 531 of the connecting channel 53 is connected to the bottom of the second cleaning tank 52, and the output port 532 of the connecting channel 53 extends toward the middle of the first cleaning tank 51.

[0240] In this way, the positions of the first cleaning slot 51 and the second cleaning slot 52 correspond to and match the positions of the first cleaning member 41 and the second cleaning member 42 on the floor brush assembly 44 .

[0241] In this embodiment, the input port 531 of the connecting channel 53 is connected to the bottom of the second cleaning tank 52, and the output port 532 of the connecting channel 53 extends toward the middle of the first cleaning tank 51. In this way, the connecting channel 53 forms a certain slope, which makes it convenient for the cleaning equipment 40 to self-clean. When the dirt in the high cleaning tank flows to the lower cleaning tank through the connecting channel 53 under the action of gravity, the dirt is gathered together, making it convenient for the suction port 43 to suck away the dirt.

[0242] In this embodiment, the specific locations of the first cleaning tank 51 and the second cleaning tank 52 are not limited to meet various requirements. For example, the first cleaning tank 51 can be located at the front of the housing 50, while the second cleaning tank 52 can be located at the rear of the housing 50; or the second cleaning tank 52 can be located at the front of the housing 50, while the first cleaning tank 51 can be located at the rear of the housing 50. Furthermore, the second cleaning tank 52 can be located on either the left or right side of the housing 50.

[0243] See also Figure 11 and Figure 19 In some embodiments, the bottom height of the second cleaning tank 52 is greater than the top height of the first cleaning tank 51 , and the connecting channel 53 is inclined, or the connecting channel 53 extends at a slope of 5° to 15°.

[0244] In this way, the connecting channel 53 can form a certain slope, so that the dirt in the second cleaning tank 52 can flow to the location of the first cleaning tank 51 through the connecting channel 53 under the action of gravity.

[0245] In this embodiment, the bottom height of the second cleaning tank 52 can be higher than the top height of the first cleaning tank 51, so that the connecting channel 53 connecting the first cleaning tank 51 and the second cleaning tank 52 will definitely form a slope with a certain inclination angle, so that the dirt in the second cleaning tank 52 can flow to the first cleaning tank 51 along the slope in the connecting channel 53 under the action of gravity.

[0246] Alternatively, when the second cleaning tank 52 is positioned no higher than the first cleaning tank 51, the connecting channel 53 can extend from the second cleaning tank 52 to the first cleaning tank 51 at a slope of 5° to 15°. For example, the connecting channel 53 can extend downward at a slope of 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°. Ensuring that the input port 531 of the connecting channel 53 is higher than the output port 532 allows dirt within the second cleaning tank 52 to flow along the inclined connecting channel 53 toward the first cleaning tank 51 under the action of gravity, thereby gathering the dirt and facilitating its removal by the suction port 43. In this way, even without suction assistance, the dirt can at least partially converge toward the first cleaning tank 51, ensuring the self-cleaning effect of the second cleaning member 42 within the second cleaning tank 52.

[0247] In a preferred embodiment, the connecting channel 53 extends downward at a slope of 10°. In this way, the input port 531 of the connecting channel 53 is ensured to be higher than the output port 532, so that the dirt in the second cleaning tank 52 can flow to the first cleaning tank 51 along the inclined connecting channel 53 under the action of gravity, and the connecting channel 53 will not occupy too much space on the cleaning base 100.

[0248] See also Figures 11 to 16 In some embodiments, the second cleaning member 42 is rotatably mounted on the floor brush assembly 44 of the cleaning device 40 , and one or more wipers 521 are provided at the bottom of the second cleaning tank 52 . The wipers 521 extend from the sidewalls of the second cleaning tank 52 toward the center of the tank bottom. When the cleaning device 40 is docked with the cleaning base 100 , the wipers 521 are in interference contact with the second cleaning member 42 .

[0249] In this way, the dirt and sewage on the second cleaning member 42 are scraped off by the wiper 521 , thereby cleaning the second cleaning member 42 .

[0250] Specifically, after the cleaning device 40 is docked with the cleaning base 100, the second cleaning member 42 is in interference contact with the wiper 521 in the second cleaning tank 52, and the second cleaning member 42 rotates at the same time, so that the wiper 521 in interference contact with the second cleaning member 42 can scrape off the dirt and sewage on the second cleaning member 42, scrape the dirt into the second cleaning tank 52, and then discharge the dirt into the first cleaning tank 51 through the connecting channel 53, and finally suck the dirt away through the sewage suction port 43, which facilitates the centralized treatment of dirt and ensures the self-cleaning effect.

[0251] It should be noted that the cleaning device 40 is provided with a wiper (not shown in the figure) that cooperates with the roller brush. The wiper can squeeze the dirt and sewage in the roller brush into the first cleaning tank 51 when the roller brush is cleaning.

[0252] See also Figure 11 、 Figure 16 and Figure 20 In some embodiments, the side wall of the second cleaning tank 52 is provided with an air outlet 522 , and the air outlet 522 is lower than the top surface height of the wiper 521 , or, when the cleaning device 40 is docked with the cleaning base 100 , the air outlet 522 is located below the second cleaning member 42 .

[0253] In this way, after the second cleaning member 42 is flushed and cleaned, the air outlet 522 can blow out dry air to take away excess moisture, so that the second cleaning member 42 and the second cleaning tank 52 are dried quickly, effectively inhibiting the growth of bacteria.

[0254] In this embodiment, the sidewall of the second cleaning tank 52 is provided with an air outlet 522. The air outlet 522 can blow out dry air to ventilate the second cleaning tank 52 and the second cleaning member 42 after self-cleaning, accelerate the drying of the second cleaning tank 52 and the second cleaning member 42, and inhibit bacterial growth. Furthermore, to prevent the second cleaning member 42 from blocking the air outlet 522 and ensure effective ventilation and drying, the air outlet 522 is positioned below the top surface of the wiper 521; alternatively, when the cleaning device 40 is docked with the cleaning base 100, the air outlet 522 is positioned below the second cleaning member 42. This embodiment does not limit the specific location of the air outlet 522; as long as the air outlet 522 is not blocked and can meet the ventilation requirements of the second cleaning tank 52 and the second cleaning member 42, it is sufficient.

[0255] In one embodiment, when the second cleaning member 42 extends into the second cleaning tank 52, the wiper 521 makes interference contact with the second cleaning member 42 to flush and clean the second cleaning member 42. After the flushing and cleaning is completed, the second cleaning member 42 can be lifted relative to the second cleaning tank 52 so that the air outlet 522 is located below and aligned with the second cleaning member 42, ensuring that the second cleaning member 42 and the second cleaning tank 52 dry quickly.

[0256] See also Figure 11 、 Figure 16 and Figure 19 In some embodiments, the bottom of the second cleaning tank 52 is funnel-shaped, with the lowest point of the second cleaning tank 52 located at the center of the bottom. The input port 531 of the connecting channel 53 is located at the lowest point of the second cleaning tank 52. When the cleaning device 40 is docked with the cleaning base 100, the rotation center of the second cleaning member 42 is located above the center of the bottom of the second cleaning tank 52.

[0257] In this way, the sewage in the second cleaning tank 52 is easily collected and discharged into the first cleaning tank 51 through the connecting channel 53, thereby ensuring a self-cleaning effect.

[0258] In this embodiment, when the second cleaning member 42 performs self-cleaning within the second cleaning tank 52, the wastewater generated by cleaning falls into the second cleaning tank 52 and converges toward the lowest point of the second cleaning tank 52 (i.e., the center of the funnel-shaped tank bottom). In other words, the wastewater converges at the center of the tank bottom. The wastewater then enters the connecting channel 53 through the input port 531 connected to the lowest point (i.e., the center) of the tank bottom. It then flows through the connecting channel 53 and into the output port 532 into the first cleaning tank 51, where it is ultimately sucked away by the wastewater suction port 43. In this manner, the cleaning device 40 completes its self-cleaning process.

[0259] See also Figure 17 and Figure 18In some embodiments, the second cleaning member 42 includes a wiping cloth 421 and a tray 422 . The wiping cloth 421 is mounted on the tray 422 and is annular. When the cleaning device 40 is docked with the cleaning base 100 , the inner ring area of ​​the wiping cloth 421 is located directly above the input port 531 of the connecting channel 53 , and the wiper 521 spans the width of the ring of the wiping cloth 421 .

[0260] In this way, it can be ensured that during self-cleaning, the wiper 521 can completely scrape the entire wiping cloth 421, ensuring the self-cleaning efficiency of the wiping cloth 421. The wiper 521 spans the ring width of the wiping cloth 421 and can quickly squeeze out water.

[0261] Specifically, when the cleaning device 40 is docked with the cleaning base 100, the cleaning device tray 422, the annular wiping cloth 421 on the tray 422, and the bottom of the second cleaning tank 52 form a concentric circle design. At this point, the inner ring area of ​​the wiping cloth 421 is located directly above the input port 531 of the connecting channel 53 at the center of the tank bottom. Simultaneously, the wiper 521 located within the second cleaning tank 52 is in interference contact with the annular wiping cloth 421 on the second cleaning member 42. The length of the wiper 521 is greater than the width of the wiping cloth 421, ensuring that the wiper 521 can completely scrape the entire wiping cloth 421 during self-cleaning, thereby ensuring the self-cleaning efficiency of the wiping cloth 421.

[0262] See also Figure 11 and Figure 19 In some embodiments, the cleaning base 100 further includes a base water pump 60, and the second cleaning tank 52 is provided with a spraying member 61. The base water pump 60 is connected to the spraying member 61, and the spraying member 61 includes a first water spraying member 611 and a second water spraying member 612. The first water spraying member 611 is used to spray upward to wet the second cleaning member 42, and the second water spraying member 612 is used to spray toward or along the bottom of the tank to rinse the second cleaning tank 52; the base water pump 60 supplies water to the spraying member 61 by connecting to the base station water tank provided by the cleaning base 100, or the base water pump 60 supplies water to the spraying member 61 by connecting to an external water source.

[0263] Thus, the provision of the spraying member 61 can enhance the self-cleaning effect of the cleaning device 40. The first spraying member 611 sprays upward to wet the second cleaning member 42, which can assist in cleaning the second cleaning member 42; the second spraying member 612 can spray horizontally toward or along the bottom of the tank, thereby flushing the second cleaning tank 52.

[0264] In this embodiment, to ensure the self-cleaning effect of the second cleaning element 42, a base water pump 60 is further provided on the cleaning base 100, and a spray element 61 is further provided on the second cleaning tank 52. The base water pump 60 is connected to the spray element 61, providing water pressure, which is then ejected by the spray element 61. The first spray element 611 of the spray element 61 sprays water upward to wet the second cleaning element 42. While rinsing away dirt from the second cleaning element 42, it also facilitates the dual action of mechanical friction and water flow between the wiper 521 and the second cleaning element 42 to effectively remove and remove dirt adhered to the second cleaning element 42, thereby ensuring a cleansing effect on the second cleaning element 42. Simultaneously, the second spray element 612 of the spray element 61 is used to spray water toward or along the bottom of the tank to rinse and clean the second cleaning tank 52, preventing excessive accumulation of dirt within the second cleaning tank 52, which could contaminate the second cleaning tank 52 and clog the input port 531 of the connecting channel 53. In this way, when the self-cleaning task is completed, the second cleaning tank 52 and the second cleaning member 42 can be kept clean.

[0265] In this embodiment, the water source required by the base water pump 60 is not limited to meet various needs. For example, the base water pump 60 can be connected to the base water tank provided by the cleaning base 100 to supply water to the injection unit 61; alternatively, the base water pump 60 can be connected to an external water source to supply water to the injection unit 61.

[0266] See also Figures 10 to 12 In some embodiments, the housing 50 includes a carrying panel 54 for carrying the cleaning device 40, the first cleaning tank 51 and the second cleaning tank 52 are arranged on the carrying panel 54, the connecting channel 53 is located below the carrying panel 54 or attached to the lower surface of the carrying panel 54, and the input port 531 and the output port 532 of the connecting channel 53 are both facing upward.

[0267] In this way, it is convenient to place the cleaning device 40 on the cleaning base 100 for self-cleaning.

[0268] Specifically, the supporting panel 54 of the housing 50 can support the cleaning device 40, facilitating placement of the first cleaning member 41 and the second cleaning member 42 of the cleaning device 40 on the supporting panel 54 for self-cleaning. Furthermore, the connection channel 53 is located below the supporting panel 54, enhancing the aesthetics of the cleaning base 100. The input port 531 of the connection channel 53 faces upward, facilitating the suction of wastewater formed within the second cleaning tank 52 into the wastewater suction port 43 via the connection channel 53. Furthermore, the output port 532 of the connection channel 53 also faces upward, facilitating that the wastewater above the output port 532 can be drawn away from the output port 532 after docking, thereby achieving the purpose of self-cleaning.

[0269] In this embodiment, the specific configuration of the connecting channel 53 below the supporting panel 54 is not limited, so as to meet various requirements. For example, the connecting channel 53 can be attached to the lower surface of the supporting panel 54, which simplifies the production of the supporting panel 54 and facilitates the user's removal of the connecting channel 53 for maintenance or replacement. Alternatively, the connecting channel 53 and the supporting panel 54 can be integrally formed, which improves the airtightness of the connecting channel 53 and enhances the efficiency of the suction port 43 in sucking waste from the second cleaning tank 52.

[0270] See also Figures 19 to 22 In some embodiments, the connecting channel 53 is provided with a one-way valve 533 , which is connected in a direction from the input port 531 to the output port 532 .

[0271] In this way, it is ensured that the sewage can only flow from the second cleaning tank 52 to the first cleaning tank 51, preventing the sewage from flowing back.

[0272] Specifically, in this embodiment, a one-way valve 533 is provided in the connecting channel 53. The one-way valve 533 can only be opened toward the output port 532 of the connecting channel 53. This allows sewage from the second cleaning tank 52 to pass through the input port 531 of the connecting channel 53, pushing open the one-way valve 533 and flow toward the output port 82 of the connecting channel 53. Finally, the sewage flows into the first cleaning tank 51 and is sucked into the sewage suction port 43, completing self-cleaning. However, when the sewage attempts to flow back into the second cleaning tank 52, the one-way valve 533 cannot open toward the input port 531, preventing the sewage from flowing back into the second cleaning tank 52. Furthermore, the pressure of the backflowing water causes the one-way valve 533 to close tighter, further preventing the sewage from flowing back.

[0273] In the embodiment of the present application, the specific location of the one-way valve 533 in the connecting channel 53 is not limited to meet different needs. In a preferred embodiment, the one-way valve 533 can be arranged in the connecting channel 53 near the output port 532.

[0274] See also Figure 20 In some embodiments, the cleaning base 100 includes a fan 70 and an air duct 71 disposed in the housing 50 . The fan 70 is used to generate airflow, and the air duct 71 is used to guide the airflow generated by the fan 70 into the first cleaning tank 51 and the second cleaning tank 52 .

[0275] In this way, the drying of the first cleaning tank 51 and the second cleaning tank 52 can be accelerated, and the growth of bacteria can be suppressed.

[0276] Specifically, the fan 70 can generate airflow and introduce the airflow into the first cleaning tank 51 and the second cleaning tank 52 through the air duct 71. The introduced airflow can take away the moisture from the two cleaning tanks and the cleaning parts in the cleaning tanks, speed up the drying speed of the two cleaning tanks, and prevent the cleaning tanks from breeding bacteria and stinking due to long-term moisture, thereby bringing a better user experience.

[0277] See also Figure 20 In some embodiments, the air duct 71 includes a first air duct 711, a second air duct 712, and a third air duct 713. The first air duct 711 is used to divert the airflow generated by the fan 70 to the second air duct 712 and the third air duct 713. The second air duct 712 connects the first cleaning tank 51 and the first air duct 711. The third air duct 713 connects the second cleaning tank 52 and the first air duct 711.

[0278] In this way, air drying of different cleaning tanks can be achieved through different air ducts 71 .

[0279] Specifically, the fan 70 can generate an airflow that first enters the first air duct 711 and then is diverted through the first channel to the second air duct 712 and the third air duct 713. The airflow diverted to the second air duct 712 is blown toward the first cleaning tank 51 for drying the first cleaning tank 51 and the first cleaning member 41 therein. The airflow diverted to the third air duct 713 is blown toward the second cleaning tank 52 for drying the second cleaning tank 52 and the second cleaning member 42 therein. In this way, different cleaning tanks can be dried through different air ducts 71.

[0280] See also Figure 20 In some embodiments, the cleaning base 100 includes a heating element 72 disposed in the first air duct 711 , and the heating element 72 is used to heat the air flowing through the cleaning base 100 .

[0281] In this way, the cleaning tank can be dried more quickly to avoid the problem of moisture, bacterial growth and odor.

[0282] Specifically, the heating element 72 arranged in the first air duct 711 can heat the air flow flowing through the first air duct 711, so that the heated air flow is then diverted through the second air duct 712 and the third air duct 713, and blown into the first cleaning tank 51 and the second cleaning tank 52, thereby accelerating the drying of the cleaning tanks.

[0283] See also Figures 10 to 14The embodiment of the present application further provides a cleaning base 100 for docking a cleaning device 40. The cleaning base 100 includes a shell 50. The shell 50 is provided with a first cleaning slot 51 and a second cleaning slot 52. The first cleaning slot 51 is used to carry the first cleaning member 41 of the cleaning device 40, and the second cleaning slot 52 is used to carry the second cleaning member 42 of the cleaning device 40. The shell 50 is provided with a connecting channel 53. The input port 531 of the connecting channel 53 is connected to the second cleaning slot 52, and the output port 532 of the connecting channel 53 is located around or inside the first cleaning slot 51. When the cleaning device 40 is docked with the cleaning base 100, the sewage suction port 43 of the cleaning device 40 is connected to the first cleaning slot 51, and the sewage suction port 43 of the cleaning device 40 is connected to the output port 532 of the connecting channel 53. The liquid output from the output port 532 of the connecting channel 53 can be sucked into the sewage suction port 43.

[0284] In this way, the connecting channel 53 is connected to the first cleaning tank 51 and the second cleaning tank 52, so that the first cleaning member 41 and the second cleaning member 42 can be cleaned simultaneously.

[0285] In this embodiment, when the cleaning device 40 is docked with the cleaning base 100, the suction port 43 communicates with the first cleaning tank 51 to suck away dirt in the first cleaning tank 51. Simultaneously, the suction port 43 communicates with the output port 532 of the connecting channel 53, transmitting negative pressure suction into the connecting channel 53 through the output port 532. The negative pressure suction is then transmitted to the input port 531 of the connecting channel 53 via the connecting channel 53, and then the negative pressure suction is transmitted to the second cleaning tank 52 to suck away dirt in the first cleaning tank 51. In this way, the first cleaning member 41 and the second cleaning member 42 can be cleaned simultaneously, improving the self-cleaning efficiency.

[0286] In other embodiments, the cleaning device 40 may have two sewage suction ports 43, one of which is connected to the first cleaning tank 51, and the other of which is connected to the output port 532 of the connecting channel 53. In this embodiment, the number of sewage suction ports 43 and the manner in which they are connected to the first cleaning tank 51 and the output port 532 of the connecting channel 53 are not limited to meet various needs.

[0287] See also Figure 11 、 Figure 12 and Figure 19. The embodiment of the present application also provides a cleaning base 100 for docking the cleaning device 40. The cleaning base 100 includes a shell 50 and a base suction assembly 80. The shell 50 is provided with a first cleaning groove 51 and a second cleaning groove 52. The first cleaning groove 51 is used to carry the first cleaning member 41 of the cleaning device 40, and the second cleaning groove 52 is used to carry the second cleaning member 42 of the cleaning device 40; the shell 50 is provided with a connecting channel 53, the input port 531 of the connecting channel 53 is connected to the second cleaning groove 52, and the output port 532 thereof is connected to the input end 81 of the base suction assembly 80; the cleaning base 100 also includes a base sewage tank 90, and the output end 82 of the base suction assembly 80 is connected to the base sewage tank 90, or the cleaning base 100 also includes a sewage pipe 91, one end of the sewage pipe 91 is connected to the output end 82 of the base suction assembly 80, and the other end thereof is used to connect to an external sewage outlet (such as a floor drain).

[0288] In this way, the cleaning base 100 can automatically process the sewage generated by cleaning, making the self-cleaning work more automated and reducing the pressure of the sewage tank of the cleaning equipment 40.

[0289] In this embodiment, the cleaning of the first cleaning tank 51 requires the participation of the sewage suction port 43 on the cleaning device 40, while the cleaning of the second cleaning tank 52 requires the drainage pipe 91 of the cleaning base 100. The base suction assembly 80 of the cleaning base 100 can suction away the sewage generated during self-cleaning. Specifically, the input end 81 of the base suction assembly 80 on the cleaning base 100 is connected to the output port 532 of the connecting channel 53, allowing the base suction assembly 80 to suction away the sewage in the connecting channel 53 and the cleaning tank. At the same time, when the placement location of the cleaning base 100 does not have a good sewage discharge environment, the output end 82 of the base suction assembly 80 can be connected to the base sewage tank 90, so that the sucked sewage can be stored in the base sewage tank 90 first, so that it only needs to clean the base sewage tank 90 regularly; or, when the placement location of the cleaning base 100 has a good sewage discharge environment, the output end 82 of the base suction assembly 80 can be directly connected to an external sewage outlet, so that the sucked sewage can be directly discharged without additional cleaning, which is more convenient to use. In this embodiment, the specific sewage discharge method of the cleaning base 100 is not limited to meet various needs.

[0290] See also Figure 12 and Figure 21 as well as Figure 22 The embodiment of the present application further provides a cleaning system 200 , which includes a cleaning device 40 and any one of the cleaning bases 100 described above. The cleaning base 100 is used to supply power to the cleaning device 40 and / or clean the cleaning device 40 .

[0291] In this embodiment, the type of cleaning device 40 is not limited to meet various needs. For example, the cleaning device 40 can be a floor scrubber, and the cleaning base 100 can serve as a dedicated base station for the floor scrubber. The cleaning system 200 includes the cleaning base 100 and the aforementioned cleaning device 40. The cleaning base 100 is used to power the cleaning device 40 and / or clean the cleaning device 40. The cleaning system 200 can have all the technical features and technical effects of the aforementioned cleaning device 40, enabling the cleaning system 200 to have excellent cleaning and self-cleaning effects, as well as good operational stability and service life, thereby enhancing the user experience.

[0292] In this embodiment, the self-cleaning operation of the cleaning device 40 adopts a dual-slot separate cleaning design, which performs the self-cleaning operations of the roller brush assembly 20 and the side brush member 32 separately. This prevents cross-contamination between the roller brush assembly 20 and the side brush member 32 during self-cleaning, thereby ensuring cleaning quality. Of course, different cleaning modes can also be set for the roller brush assembly 20 and the side brush member 32 to ensure optimal self-cleaning effect.

[0293] See also Figure 22 and Figure 23 The present application also provides a cleaning control method for controlling a cleaning system 200 as described above. The cleaning system 200 includes a first water supply line 201 for supplying water to a first cleaning element 41 and a second water supply line 202 for supplying water to a second cleaning element 42 .

[0294] Cleaning control methods include:

[0295] S1, detecting whether the cleaning device 40 is docked with the cleaning base 100, and after docking, controlling the cleaning system 200 to enter the cleaning mode;

[0296] S2, in the cleaning mode, controls the negative pressure component of the cleaning system 200 to start so that the suction port 43 generates suction, controls the first cleaning member 41 and the second cleaning member 42 to rotate relative to the cleaning base 100, and controls the first water supply pipe 201 to supply water to the first cleaning member 41, and the second water supply pipe 202 to supply water to the second cleaning member 42; the second water supply pipe 202 eventually stops supplying water, and after a certain period of time, the first water supply pipe 201 eventually stops supplying water.

[0297] It should be noted that water may be supplied intermittently multiple times in the cleaning mode, and the final stop of water supply refers to the time point when the corresponding water supply pipeline ends the last water supply in this cleaning mode.

[0298] Since the first cleaning tank 51 is located downstream of the sewage discharge of the second cleaning tank 52, the first cleaning tank 51 is easily affected by the sewage discharge of the second cleaning tank 52. If the cleaning in the first cleaning tank 51 stops, the second cleaning tank 52 is still cleaning, there is a risk that the sewage discharged from the second cleaning tank 52 will overflow into the first cleaning tank 51 along the connecting pipe, which will easily cause the first cleaning part 41 that has been cleaned to be re-contaminated. In order to avoid this risk, the present application strictly controls the sewage discharge time of the two cleaning tanks through the water supply time of the water supply pipeline, so that the cleaning work in the first cleaning tank 51 will stop after the cleaning work in the second cleaning tank 52 stops, thereby avoiding the problem of repeated contamination.

[0299] In this embodiment, when the cleaning control method detects that the cleaning device 40 and the cleaning base 100 have been docked, the cleaning system 200 is controlled to enter cleaning mode. In cleaning mode, the cleaning control method activates the negative pressure component of the cleaning system 200 to generate suction at the suction port 43, thereby removing wastewater generated during cleaning. Simultaneously, the first and second cleaning elements 41, 42 are controlled to rotate relative to the cleaning base 100, enabling the wiper 521 to scrape off any debris from the cleaning elements. Furthermore, the first water supply line 201 is controlled to supply water to the first cleaning element 41, and the second water supply line 202 is controlled to supply water to the second cleaning element 42, thereby moistening the first and second cleaning elements 41, 42. This allows any debris on the cleaning elements to dissolve in the water flow and be scraped off by the wiper 521 into the cleaning tank. The wastewater in the second cleaning tank 52 is then discharged into the first cleaning tank 51 along the connecting channel 53, where it is combined with the wastewater in the first cleaning tank 51 and removed by the suction port 43, resulting in more efficient self-cleaning.

[0300] After self-cleaning is complete, the second water supply line 202 finally stops supplying water. This allows the remaining water in the second cleaning tank 52 to drain along the connecting channel 53 into the first cleaning tank 51. When only unmovable residual water droplets remain in the second cleaning tank 52, the first water supply line 201 finally stops supplying water, and the sewage suction port 43 removes the remaining accumulated water. It should be understood that the sewage suction port 43 operates continuously throughout the cleaning process, continuously removing the wastewater generated during cleaning. At this point, the cleaning system 200 completes its cleaning mode.

[0301] See also Figure 24 In some embodiments, the cleaning control method further comprises:

[0302] S3, after the cleaning mode is completed, controlling the cleaning system 200 to enter the drying mode;

[0303] S4, in the drying mode, controls the air outlet 522 corresponding to the second cleaning tank 52 to blow air, and at the same time controls the negative pressure component of the cleaning system 200 to start so that the suction port 43 generates suction, thereby increasing the wind pressure in the connecting channel 53, so that the accumulated water in the connecting channel 53 can be carried out with the air flow to the suction port 43 for recovery.

[0304] In this way, the wind pressure generated by the air outlet 522 and the wind pressure generated by the sewage suction port 43 are used simultaneously to perform a superimposed effect, thereby quickly accelerating the drying of the cleaning parts and the cleaning tank, avoiding the emission of odor due to bacterial growth, and bringing a better user experience.

[0305] In this embodiment, after the cleaning mode is completed, the cleaning system 200 is controlled to enter the drying mode. At this time, the air outlet 522 located in the second cleaning tank 52 continuously blows air, while the sewage suction port 43 in the first cleaning tank 51 continuously generates negative pressure suction. This combination of blowing and suction creates rapid convection within the cleaning tank and connecting passage 53, allowing any remaining water to be quickly dried by the airflow and the moisture to be sucked away. This accelerates the drying of the cleaning elements and the cleaning tank, prevents odors caused by bacterial growth, and provides a better user experience.

[0306] See also Figure 25 In some embodiments, the air supply assembly of the cleaning base 100 can selectively supply air to the first cleaning tank 51 and the second cleaning tank 52 separately or simultaneously;

[0307] S5 , in the drying mode, first controlling the air supply assembly to supply air only to the second cleaning tank 52 for a first period of time, and then controlling the air supply assembly to supply air to both the first cleaning tank 51 and the second cleaning tank 52 at the same time.

[0308] When the power of the air supply component is constant, the wind pressure generated by blowing air into only one cleaning tank is generally greater than the wind pressure generated by blowing air into two cleaning tanks at the same time. By utilizing the larger wind pressure generated by blowing air alone, the ability to discharge accumulated water in the connecting channel can be further improved, thereby reducing the drying time in the connecting channel.

[0309] In this embodiment, the air supply component of the cleaning base 100 can only supply air to the first cleaning tank 51, for air-drying the first cleaning tank 51 and the first cleaning member 41; or, the air supply component of the cleaning base 100 can only supply air to the second cleaning tank 52, for air-drying the second cleaning tank 52 and the second cleaning member 42; or, the air supply component of the cleaning base 100 can simultaneously supply air to the first cleaning tank 51 and the second cleaning tank 52, for air-drying the two cleaning tanks and the two cleaning members at the same time.

[0310] For example, in drying mode, air can be supplied to the second cleaning tank 52 for a period of time. That is, air can be supplied only to the second cleaning tank 52 during the first period of time. After the second cleaning tank 52 and the second cleaning member 42 are properly dried, air can then be supplied to the first cleaning tank 51 and the second cleaning tank 52 simultaneously. This is the second period of time, and both cleaning tanks and the two cleaning members can be dried simultaneously during the second period of time. It is best to avoid supplying air to both cleaning tanks at the beginning, as this will cause moisture to accumulate in the second cleaning tank 52 after passing through the connecting channel 53, thereby affecting drying efficiency.

[0311] See also Figure 26 In some embodiments, the cleaning device 40 further includes a lifting assembly 46 for adjusting the lifting of the second cleaning member 42;

[0312] Cleaning control methods also include:

[0313] S6, in the cleaning mode, the lifting assembly 46 drives the second cleaning member 42 to extend into the second cleaning tank 52, and makes the wiper 521 of the second cleaning tank 52 come into interference contact with the second cleaning member 42;

[0314] S7, in the drying mode, the lifting assembly 46 drives the second cleaning member 42 to separate from the wiper 521, and controls the air outlet 522 corresponding to the second cleaning tank 52 to blow air.

[0315] In this embodiment, the lifting assembly 46 drives the second cleaning member 42 to contact the wiper 521 of the second cleaning tank 52 and achieve an interference fit. The lifting assembly 46 can provide downward pressure on the second cleaning member 42 to enhance the scraping and cleaning effect of the wiper 521, and can also reduce the distance between the second cleaning member 42 and the nozzle, thereby improving the water spray cleaning effect. It should be noted that at this time, the air outlet 522 is easily blocked by the side of the second cleaning member 42. In addition, after cleaning is completed, the second cleaning member 42 can be adjusted to separate from the wiper 521. At this time, the air outlet 522 is between the second cleaning member 42 and the bottom of the second cleaning tank 52, leaving sufficient exhaust space for the air outlet 522, preventing the second cleaning member 42 from being wetted by the bottom surface again, and increasing the drying convection effect.

[0316] See also Figure 26 The embodiment of the present application further provides a cleaning control method for controlling the cleaning system 200 as required above, wherein the cleaning device 40 further includes a lifting assembly 46 for adjusting the lifting of the second cleaning member 42. The cleaning control method includes:

[0317] S6, in the cleaning mode, the lifting assembly 46 drives the second cleaning member 42 to extend into the second cleaning tank 52, and makes the wiper 521 of the second cleaning tank 52 come into interference contact with the second cleaning member 42;

[0318] S7, in the drying mode, the lifting assembly 46 drives the second cleaning member 42 to separate from the wiper 521, and controls the air outlet 522 corresponding to the second cleaning tank 52 to blow air.

[0319] In the present application, when the power of the air supply component is constant, the wind pressure generated by blowing air into only one cleaning tank is generally greater than the wind pressure generated by blowing air into two cleaning tanks at the same time. By utilizing the larger wind pressure generated by blowing air alone, the ability to discharge accumulated water in the connecting channel 53 can be further improved, thereby reducing the drying time in the connecting channel 53.
