Abstract
Description
Technical Field
[0001] This utility model relates to the field of sweeping robots, and in particular to a cleaning system, a base station, and a sweeping robot. Background Technology
[0002] With the rapid development of smart home technology, cleaning robots are becoming increasingly popular due to their highly automated cleaning functions, providing users with great convenience. Current cleaning robots are typically equipped with a dedicated base station, which provides the robot with a docking location and performs multiple maintenance functions such as mop washing, autonomous charging, and garbage collection.
[0003] However, in practice, it has been found that when cleaning base stations using a mop, wastewater and dirt generated during the cleaning process tend to remain and accumulate on the surface of the base station chassis. If not cleaned thoroughly and promptly, this can not only breed bacteria and produce odors but also affect the effectiveness of subsequent cleaning. This necessitates frequent manual cleaning of the base station chassis by users, which to some extent diminishes the convenience of the smart product experience.
[0004] To address this issue, existing technologies have incorporated movable cleaning components such as scrapers within the base station to reduce dirt residue on the chassis through scraping action. However, these solutions typically require a separate drive mechanism (such as a motor and transmission system) for the scraper, which undoubtedly increases the complexity of the base station's internal structure and overall cost, while also leading to higher energy consumption and potential failure risks. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cleaning system, a base station and a sweeping robot.
[0006] This utility model provides a cleaning system, including:
[0007] A robotic vacuum cleaner with a rotating mop head at the bottom;
[0008] A base station includes a cleaning chassis, a cleaning assembly disposed on the cleaning chassis, and a suction assembly. The cleaning assembly includes a first cleaning part rotatably disposed on the cleaning chassis. The suction assembly has a suction port facing the cleaning chassis and is configured to actively suction the waste liquid in the cleaning chassis.
[0009] When the sweeping robot stops at the base station, the wiping part and the first cleaning part are detachably driven together, so that the wiping part can drive the first cleaning part to rotate, so as to guide the sewage to the suction port.
[0010] In the above technical solution, the inner bottom surface of the cleaning chassis is inclined to the location of the suction port.
[0011] In the above technical solution, the sweeping robot is provided with two mop parts side by side, and the cleaning component includes two first cleaning parts, wherein the suction port is located between the two first cleaning parts.
[0012] In the above technical solution, the wiping cloth part includes a wiping cloth tray and a wiping cloth. The bottom surface of the wiping cloth tray is provided with a first connecting structure, and the wiping cloth is disposed on the bottom surface of the wiping cloth tray and avoids the first connecting structure.
[0013] The first cleaning part has a rotating shaft, and the top surface of the rotating shaft is provided with a second connecting structure;
[0014] When the sweeping robot stops at the base station, the first connection structure and the second connection structure can be detachably engaged and driven.
[0015] In the above technical solution, the first connecting structure includes a plurality of first protruding ribs arranged circumferentially, and the second connecting structure includes a plurality of second protruding ribs arranged circumferentially. When the sweeping robot stops, the first protruding ribs and the second protruding ribs interlock and engage with each other to transmit torque.
[0016] In the above technical solution, one of the first connecting structure and the second connecting structure is provided with a positioning groove, and the other is provided with a positioning protrusion adapted to the positioning groove. When the positioning protrusion is inserted into the positioning groove, the first connecting structure and the second connecting structure are aligned.
[0017] In the above technical solution, the cleaning component further includes a second cleaning part for cleaning the rag part, the second cleaning part being fixedly disposed on the cleaning chassis and located above the first cleaning part;
[0018] The second cleaning part is provided with a clearance opening at the location of the second connecting structure, and the first connecting structure and the second connecting structure are engaged through the clearance opening.

[0020] This utility model also provides a base station, including:
[0021] Clean the chassis;
[0022] A cleaning component, disposed on the cleaning chassis, includes a first cleaning part, which is rotatably disposed on the cleaning chassis;
[0023] A suction assembly is disposed on the cleaning chassis, the suction assembly having a suction port facing the cleaning chassis and configured to actively suck up the sewage in the cleaning chassis;
[0024] The first cleaning unit is configured to be separably driven to engage with the mop unit of the robot vacuum cleaner, so as to be driven by the mop unit to rotate and guide the sewage to the suction port.

[0026] Machine body;
[0027] The wiping cloth part is configured to be separably driven to engage with the first cleaning part of the aforementioned base station to drive the first cleaning part to rotate.
[0028] This utility model's cleaning system features a rotatable mop unit at the bottom of the robotic vacuum cleaner. When docked at a base station, this unit forms a separable transmission connection with a rotatable first cleaning unit within the base station. This allows the rotational driving force of the first cleaning unit to come directly from the robotic vacuum cleaner itself, eliminating the need for a separate motor, reduction mechanism, and related circuitry required in traditional base stations. This simplifies the complexity of the base station's internal mechanical and electrical control structures. Simultaneously, combined with a suction component that actively extracts wastewater, the wastewater is agitated by the first cleaning unit during the cleaning process and guided to the suction port for rapid extraction. This prevents wastewater from lingering and settling in the cleaning chassis, improving the efficiency and thoroughness of wastewater recovery. This helps maintain the self-cleaning state of the cleaning chassis, reducing the possibility of bacterial growth and odor generation at the source. Furthermore, the separable transmission connection ensures the robotic vacuum cleaner's independence and flexibility when performing floor cleaning tasks, while also ensuring its reliable conversion into a power source for the base station's cleaning mechanism upon returning. The entire system has a high degree of integration, with all components working closely together. Attached Figure Description

[0039] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0041] The following is a reference to the appendix. Figure 1 To be continued Figure 8 This invention describes the cleaning system, base station, and sweeping robot provided by this utility model.
[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the cleaning system provided by this utility model includes a sweeping robot and a base station.
[0043] The bottom of the sweeping robot is equipped with a rotatable mop part 300. The mop part 300 is driven by a drive mechanism such as a drive motor to rotate so as to wipe the floor when performing a sweeping task. For example, the mop part 300 is usually a disc-shaped structure, and there may be one or two of them. During the sweeping and mopping process, the sweeping robot moves autonomously, and the rotating mop part 300 wipes the floor to complete the cleaning operation.
[0044] The base station is configured as a fixed service terminal for the robotic vacuum cleaner. Its core function is to provide energy supply and cleaning maintenance for the robotic vacuum cleaner to ensure its automated and sustainable operation.
[0045] For example, depending on the water supply and sewage discharge methods, base stations can include two forms: tank-type base stations and tankless base stations. Tank-type base stations have integrated clean water tanks and wastewater tanks, used to store cleaning water and recycle wastewater after washing, respectively. The base station casing also integrates charging, cleaning, and drying modules. After the robotic vacuum cleaner docks at the base station, it can perform tasks such as charging, washing, and drying the mop head, thus preparing for the next cleaning task. Tankless base stations eliminate the need for clean water and wastewater tanks; they are directly connected to the building's water inlet and outlet pipes via pipelines. Tankless base stations also integrate charging, cleaning, and drying modules. During operation, cleaning water is directly taken from the water inlet pipe, and wastewater after washing is directly discharged into the sewer, thus avoiding the need for users to manually change the water.
[0046] In some embodiments, the base station includes a cleaning chassis 100, a cleaning component 200 disposed on the cleaning chassis 100, and a suction component. Exemplarily, the cleaning chassis 100 is fixedly or detachably installed within the base station housing, and is typically located below the docking area between the base station and the robotic vacuum cleaner. More specifically, the cleaning chassis 100 has an overall open trough-shaped, basin-shaped, or recessed structure, its shape matching the mop portion 300 at the bottom of the robotic vacuum cleaner, for example, it can be circular, elliptical, or rectangular, and its interior forms a cleaning trough for containing wastewater. The cleaning chassis 100 is primarily used to collect wastewater generated during the cleaning process. In base stations with water tanks, the wastewater generated after cleaning the mop portion 300 is actively or passively discharged into a wastewater tank for temporary storage. In base stations without water tanks, the cleaning chassis 100 is directly or via an interface connected to the building's drainage pipes to achieve direct wastewater discharge.
[0047] The cleaning assembly 200 is used to clean the cleaning cloth part 300 and the cleaning chassis 100. Specifically, the cleaning assembly 200 includes a first cleaning part 210, which is rotatably disposed on the cleaning chassis 100. The first cleaning part 210 is capable of performing scraping cleaning on the inner bottom surface of the cleaning chassis 100. Exemplarily, the first cleaning part 210 includes a rotating bracket 213 and at least one scraper 214 fixed to the rotating bracket 213. The rotating bracket 213 has a rotating shaft 211 and is rotatably supported on the bottom wall of the cleaning chassis 100 by a bearing or bushing structure. The lower edge of the scraper 214 maintains contact or a small gap with the bottom surface of the cleaning chassis 100. When the first cleaning part 210 is driven to rotate, the scraper 214 rotates accordingly around the central shaft. Because the scraper 214 is in continuous contact with the bottom surface of the cleaning chassis 100, the rotating scraper 214 can effectively disturb and scrape away dirt, hair, particles and other contaminants on the bottom surface of the cleaning chassis 100, thereby maintaining the self-cleaning function of the cleaning chassis 100. Of course, the above is only a preferred embodiment of this utility model, and its specific implementation is not limited to this.
[0048] The suction assembly has a suction port facing the cleaning chassis 100 and is configured to actively suck up the dirt in the cleaning chassis 100. When the robot vacuum stops at the base station, the mop part 300 and the first cleaning part 210 are detachably driven to rotate, so that the mop part 300 can drive the first cleaning part 210 to rotate and guide the dirt to the suction port.
[0049] For example, the suction assembly includes a suction pipe and a negative pressure component. The suction pipe extends into the cleaning chassis 100, and one end facing the cleaning chassis 100 is formed as a suction port. The other end of the suction pipe is connected to the negative pressure component, so that sewage can flow through the suction port into the sewage tank or drain pipe under the action of suction.
[0050] The cleaning system of this utility model features a rotatable mop part 300 at the bottom of the sweeping robot. When docked at a base station, this part forms a separable transmission engagement with a rotatable first cleaning part 210 inside the base station. This allows the rotational driving force of the first cleaning part 210 to come directly from the sweeping robot itself, eliminating the need for a separate motor, reduction mechanism, and related circuitry required in traditional base stations to drive the cleaning components. This simplifies the complexity of the internal mechanical and electrical control structure of the base station. Furthermore, combined with a suction component that actively extracts wastewater, the wastewater is absorbed by the first cleaning part 210 during the cleaning process. The agitation and guidance of the wastewater to the suction port allows for rapid extraction, preventing prolonged retention and sedimentation of wastewater within the cleaning chassis 100. This improves the efficiency and thoroughness of wastewater recycling, helps maintain the self-cleaning state of the cleaning chassis 100, and reduces the possibility of bacterial growth and odor generation at the source. Furthermore, the detachable transmission mechanism ensures the robot's independence and flexibility when performing floor cleaning tasks, while also ensuring its reliable conversion into a power source for the base station's cleaning mechanism upon returning to the base station. The entire system is highly integrated, with each component working closely together.
[0051] In some embodiments, the cleaning assembly 200 further includes a second cleaning part 220 for cleaning the mop part 300. The second cleaning part 220 is fixedly disposed on the cleaning chassis 100 and located above the first cleaning part 210. Exemplarily, the second cleaning part 220 may be one or more fixed scrapers or scraper strips 214, which are mounted on the cleaning chassis 100 via a bracket 213 or directly. When the robot vacuum cleaner stops at the base station, the mop part 300 of the robot vacuum cleaner can contact the second cleaning part 220. When the cloth part 300 is driven to rotate, the surface of the cloth part 300 moves relative to the fixed second cleaning part 220, causing the second cleaning part 220 to scrape, comb, or wring water from the surface of the rotating cloth part 320, thereby cleaning the cloth part 300. As the cloth part 300 rotates, it simultaneously drives the first cleaning part 210 to rotate to scrape and clean the cleaning tray 100, thereby agitating and guiding the wastewater in the cleaning tray 100 and preventing dirt from settling.
[0052] In some embodiments, the inner bottom surface of the cleaning chassis 100 is inclined towards the location of the suction port. This causes the inner bottom surface of the cleaning chassis 100 to form an inclined guide surface extending outward from the location of the suction port. During the cleaning process, the wastewater generated and the dirt scraped up by the first cleaning part 210 will be guided by the inclined bottom surface. The first cleaning part 210 can automatically collect the driving wastewater towards the lowest suction port, avoiding disorderly flow and local accumulation of wastewater in the chassis. This ensures that most of the liquid and suspended dirt can be quickly and centrally transported to the effective range of the suction port, and then efficiently extracted by the suction component.
[0053] In some embodiments, the robot vacuum cleaner has two mop sections 300 arranged side by side, and the cleaning component 200 includes two first cleaning sections 210, wherein the suction port is located between the two first cleaning sections 210.
[0054] In this embodiment, the suction port is located between the two first cleaning sections 210. When the two first cleaning sections 210 are driven to rotate and scrape, the centrifugal force or water flow disturbance generated will naturally guide and collect the sewage in their respective areas to the middle area. The suction port located in the middle confluence area can capture and suck up the concentrated sewage more efficiently, avoiding the problem of untimely or residual sewage recovery on one side due to the offset position of the suction port. It realizes the synchronous, concentrated and rapid recovery of sewage generated by cleaning on both sides, reduces the mixing and residence time of sewage in the chassis, thereby improving the timeliness and thoroughness of the cleaning process as a whole, and helps to maintain the cleanliness of the base station working environment.
[0055] In some embodiments, the wiping unit 300 includes a wiping cloth 320 tray 310 and a wiping cloth 320. The bottom surface of the wiping cloth 320 tray 310 is provided with a first connecting structure 311. The wiping cloth 320 is disposed on the bottom surface of the wiping cloth 320 tray 310 and avoids the first connecting structure 311. The first cleaning unit 210 has a rotating shaft portion 211, and the top surface of the rotating shaft portion 211 is provided with a second connecting structure 212. When the sweeping robot stops at the base station, the first connecting structure 311 and the second connecting structure 212 can be detachably engaged for transmission.
[0056] This embodiment achieves a relatively direct, reliable, and precision-alignment-free transmission structure through the separable engagement between the first connecting structure 311 on the bottom surface of the mop 320 disc 310 and the second connecting structure 212 on the top surface of the rotating shaft of the first cleaning part 210. When the robot stops, the first connecting structure 311 and the second connecting structure 212 can be docked to achieve circumferential engagement, thereby directly transmitting the rotational power of the mop 320 disc 310 to the first cleaning part 210 in the base station, causing it to rotate synchronously to perform the cleaning function. The engagement structure ensures that when the sweeping robot leaves the base station to clean the floor, the mop part 300 is completely disengaged from the first cleaning part 210, ensuring the autonomy and flexibility of the sweeping robot's movement.
[0057] Furthermore, the first connecting structure 311 includes a plurality of circumferentially spaced first protrusions 3111, and the second connecting structure 212 includes a plurality of circumferentially spaced second protrusions 2121. When the robot vacuum stops, the first protrusions 3111 and the second protrusions 2121 interlock and engage with each other to transmit torque.
[0058] In this embodiment, multiple protruding ridges are distributed circumferentially at intervals, enabling a rapid and effective mating relationship to be formed at any mating angle. This reduces the alignment accuracy requirements and improves the success rate and speed of mating. When the protruding ridges intersect, their sides serve as the main force transmission surfaces, capable of bearing and transmitting the considerable torque required to drive the first cleaning unit 210. This avoids stress concentration or slippage that may occur with a single transmission point, ensuring that the first cleaning unit 210 obtains stable and sufficient rotational power to perform effective scraping cleaning. Simultaneously, this mating method provides good constraint in both the axial and radial directions, enhancing structural stability and concentricity during transmission and reducing vibration and abnormal noise.
[0059] In some embodiments, one of the first connecting structure 311 and the second connecting structure 212 is provided with a positioning groove 410, and the other is provided with a positioning protrusion 420 adapted to the positioning groove 410. When the positioning protrusion 420 is inserted into the positioning groove 410, the first connecting structure 311 and the second connecting structure 212 are aligned.
[0060] In this embodiment, during the process of the robot vacuum docking at the base station, the pre-cooperation of the positioning protrusion 420 and the positioning groove 410 can guide the two connecting structures to quickly and accurately enter the preset relative position, realize the initial radial constraint and circumferential angle alignment, effectively overcome the positional deviation that may exist by relying solely on robot docking and positioning, and make the mop part 300 and the corresponding cleaning component 200 engage smoothly.
[0061] In some embodiments, the cleaning assembly 200 further includes a second cleaning part 220 for cleaning the cleaning cloth part 300. The second cleaning part 220 is fixedly disposed on the cleaning base 100 and located above the first cleaning part 210. The second cleaning part 220 has a clearance opening 221 corresponding to the second connecting structure 212, and the first connecting structure 311 and the second connecting structure 212 are engaged through the clearance opening 221.
[0062] By providing an avoidance opening 221 in the second connecting structure 212, a physical channel is provided for the axial docking of the first connecting structure 311 and the wiping cloth part 300, ensuring unobstructed power transmission path. This allows the second cleaning part 220 to be fixedly positioned above the first cleaning part 210, thus performing scraping or combing tasks on the wiping cloth part 300 without hindering the establishment and operation of the transmission connection between the first cleaning part 210 and the wiping cloth part 300 below. This avoids excessively raising or shifting the second cleaning part 220 to avoid interference, thereby ensuring optimal contact and cleaning effect with the wiping cloth part 300. It also enables a compact vertical arrangement of different functional modules such as cleaning and transmission, optimizing the space utilization efficiency inside the base station and improving the rationality and integrity of the structural design.
[0063] Furthermore, a portion of the second connecting structure 212 extends upward and passes through the clearance opening 221. By placing the main part of the second connecting structure 212, which is used for power transmission, on one side of the base station and extending it upward through the clearance opening 221, the first connecting structure 311 corresponding to the mop section 300 of the robotic vacuum cleaner can be designed as an embedded or low-profile flat surface. This allows the entire bottom surface of the mop 320 tray 310 to remain intact and flat after the mop 320 is installed, without any significantly protruding hard parts. When the robotic vacuum cleaner performs floor cleaning tasks and moves autonomously, the flat bottom surface of the mop section 300 ensures that the mop 320 can achieve full and even contact and wiping with the floor, avoiding cleaning blind spots, uneven pressure, or the risk of scratching the floor (especially floor gaps) that may be caused by protruding connecting structures. At the same time, the flat design also completely eliminates the possibility of the protruding structure snagging on carpet edges or floor obstacles during movement, improving the robot's passability and operational reliability in complex home environments.

[0066] A cleaning component 200 is disposed on a cleaning chassis 100 and includes a first cleaning part 210, which is rotatably disposed on the cleaning chassis 100.
[0067] A suction assembly is provided on the cleaning chassis 100. The suction assembly has a suction port facing the cleaning chassis 100 and is configured to actively suck up the dirty liquid in the cleaning chassis 100.
[0068] The first cleaning unit 210 is configured to be separably driven to engage with the mop unit 300 of the robot vacuum cleaner, so as to be driven by the mop unit 300 to rotate and guide the dirty liquid to the suction port.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0073] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
