Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a floor washing module, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment such as floor scrubbers and floor cleaning robots mainly consist of a sweeping module and a floor scrubbing module. These modules work together to perform both sweeping and scrubbing functions. However, because the sweeping and scrubbing modules are integrated into the entire machine and cannot be separated, the cleaning equipment needs to carry the scrubbing module along with it when moving autonomously to sweep. This results in higher energy consumption and reduced battery life. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a floor cleaning module that can be freely assembled onto a robotic vacuum cleaner, which helps to reduce the energy consumption of the robotic vacuum cleaner and improve its battery life.

[0005] An embodiment of this utility model also proposes a cleaning device.

[0006] An embodiment of this utility model also proposes a cleaning system.

[0007] The floor cleaning module of this utility model includes: a housing, on which a connecting part is provided for mounting to a sweeping robot and being detachable from the sweeping robot; a roller brush, which is mounted on the lower side of the housing; a clean water tank and a water spraying assembly, wherein the clean water tank is disposed inside the housing, and the water spraying assembly is connected to the clean water tank and can spray water toward at least one of the roller brush and the floor.

[0008] According to an embodiment of this utility model, the floor-washing module can be installed onto a robotic vacuum cleaner via a connecting part. Since the connecting part is detachable from the robotic vacuum cleaner, the user can selectively assemble or detach the floor-washing module and the robotic vacuum cleaner depending on the operating mode of the cleaning equipment. When the cleaning equipment is sweeping alone, the floor-washing module and the robotic vacuum cleaner can be separated, which helps reduce the energy consumption of the robotic vacuum cleaner and improve its battery life. When the cleaning equipment is washing the floor, the floor-washing module and the robotic vacuum cleaner can be assembled together, and the water spray component sprays clean water from the water tank onto the roller brush or the floor to achieve clean water cleaning of the roller brush, reducing the maintenance frequency of the floor-washing module.

[0009] In some embodiments, the water spraying assembly includes a first water path, a water pump, and a spray head. The water pump is connected in series with the first water path. One end of the first water path is connected to the clean water tank, and the other end of the first water path is connected to the spray head. The spray head is located on the front side of the roller brush.

[0010] In some embodiments, the spray head includes a plurality of water outlets, which are arranged at intervals along the axial direction of the roller brush.

[0011] In some embodiments, a partition is provided inside the housing, and the clean water tank and the roller brush are respectively arranged on the upper and lower sides of the partition.

[0012] In some embodiments, the floor cleaning module further includes a wastewater tank and a suction assembly. The wastewater tank is disposed inside the housing, and the suction assembly is connected to the wastewater tank. The suction assembly can generate negative pressure to suck the wastewater on the roller brush into the wastewater tank.

[0013] In some embodiments, the wastewater tank and the clean water tank are arranged at an axial distance along the roller brush.

[0014] In some embodiments, the suction assembly includes a suction element, a second water passage, and an air pump. The air pump is connected to the sewage chamber of the sewage tank and can generate negative pressure in the sewage chamber. One end of the second water passage is connected to the suction element, and the other end of the second water passage is connected to the sewage chamber. The suction element is provided with a suction port and is located on the rear side of the roller brush and arranged adjacent to the upper side of the roller brush.

[0015] In some embodiments, the suction device is provided with a suction chamber, one end of which is connected to the suction port and the other end of which is connected to the second water passage. The cross-sectional area of ​​the suction chamber gradually decreases from one end to the other end.

[0016] In some embodiments, the water spray assembly includes a water pump, both of which are located within the housing and are arranged on the same side of the housing in the front-rear direction.

[0017] In some embodiments, the housing includes a housing body and a cover, the housing body having a first receiving cavity, and the cover being mounted on the housing body and capable of opening and closing the opening of the first receiving cavity.

[0019] According to the cleaning device of this utility model, users can selectively assemble the floor washing module and the sweeping robot together or separate them depending on the working mode of the cleaning device. When the cleaning device is sweeping alone, the floor washing module and the sweeping robot can be separated, which helps to reduce the energy consumption of the sweeping robot and improve its endurance. When the cleaning device is washing the floor, the floor washing module and the sweeping robot can be assembled together, and the water spraying component sprays clean water from the water tank onto the roller brush or the ground to achieve clean water cleaning of the roller brush, reducing the maintenance frequency of the cleaning device.

[0020] In some embodiments, the mating part is snapped into the connecting part; or, the mating part is hooked into the connecting part; or, the mating part is magnetically connected to the connecting part.

[0021] Another embodiment of the cleaning system of this utility model includes a base station and a cleaning device, wherein the cleaning device is the cleaning device described in the embodiment of this utility model, and the cleaning device can be docked at the base station.

[0022] According to the cleaning system of this utility model, users can selectively assemble or separate the floor-washing module and the sweeping robot based on the working mode of the cleaning equipment. When the cleaning equipment is sweeping alone, the floor-washing module and the sweeping robot can be separated, which helps to reduce the energy consumption of the sweeping robot and improve its battery life. When the cleaning equipment is washing the floor, the floor-washing module and the sweeping robot can be assembled together, and the water spraying component sprays clean water from the water tank onto the roller brush or the floor to achieve clean water cleaning of the roller brush, reducing the maintenance frequency of the cleaning equipment.

[0040] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The following is a reference appendix. Figures 1 to 8 This invention describes a floor cleaning module, cleaning equipment, and cleaning system according to embodiments of the present invention.

[0042] like Figures 1 to 5As shown, the floor cleaning module of this utility model embodiment includes: a housing 1, a roller brush assembly 2, a clean water tank 3, and a water spray assembly 4. The housing 1 is provided with a connecting part 11, which is used to install onto a sweeping robot 8 and can be separated from the sweeping robot 8. The roller brush assembly 2 includes a roller brush 21, which is installed on the lower side of the housing 1. The clean water tank 3 is disposed inside the housing 1. The water spray assembly 4 is connected to the clean water tank 3 and can spray water toward at least one of the roller brush 21 and the ground.

[0043] According to an embodiment of the present invention, the floor-washing module can be installed onto the robot vacuum cleaner 8 via the connecting part 11. Since the connecting part 11 is detachable from the robot vacuum cleaner 8, the user can selectively assemble the floor-washing module and the robot vacuum cleaner 8 together or separate them depending on the working mode of the cleaning equipment. In other words, the floor-washing module can be freely assembled onto the robot vacuum cleaner 8.

[0044] When the cleaning equipment is used for sweeping alone, the floor washing module and the sweeping robot 8 can be separated, which helps reduce the energy consumption of the sweeping robot 8 and improve its battery life. When the cleaning equipment is used for floor washing, the floor washing module and the sweeping robot 8 can be assembled together. The water spraying component 4 sprays clean water from the clean water tank 3 onto the roller brush 21 or the ground to achieve clean water cleaning of the roller brush 21, reducing the maintenance frequency of the floor washing module.

[0045] Understandably, the roller brush 21 is in contact with the ground, and when the robot vacuum cleaner 8 moves the floor cleaning module, the roller brush 21 can move relative to the ground. The water spray component 4 can spray water towards the roller brush 21, and it can also spray water towards the ground in front of the roller brush 21 to perform deep cleaning of the ground.

[0046] In this example of the present invention, the roller brush assembly 2 also includes a drive motor (not shown), which is connected to the roller brush 21 to drive the roller brush 21 to rotate relative to the housing 1, thereby improving the floor cleaning effect of the roller brush 21.

[0047] In other examples, the floor cleaning module may not require a drive motor to rotate the roller brush 21.

[0048] For example, the robotic vacuum cleaner 8 can transmit power to the roller brush 21 through a linkage component. It can be understood that the drive motor of the robotic vacuum cleaner 8 can both drive its own sweeping brush to rotate and transmit the power of the drive motor to the roller brush 21 through the linkage component. This can reduce the number of power sources, reduce production costs, and make the structure of the cleaning equipment more compact.

[0049] For example, the roller brush 21 can be installed on the housing 1 in a motorless manner, and the sweeping robot 8 drives the floor cleaning module to complete the floor cleaning work of the roller brush 21.

[0050] It should be noted that the sweeping robot 8 can be a robot with only sweeping function, or it can be a sweeping and mopping robot. This utility model does not limit the type of sweeping robot 8.

[0051] The cleaning device of this utility model has at least the following functions:

[0052] (1) Single sweeping and mopping mode. In this mode, the sweeping robot 8 is separated from the floor washing module, and the sweeping robot 8 moves independently to perform sweeping and mopping (dry mopping) operations.

[0053] (2) Sweep and mop first, then wash. In this mode, the sweeping robot 8 separates from the washing module and moves independently to perform sweeping and mopping (dry mopping). After sweeping and mopping, the sweeping robot 8 returns to the base station and reassembles with the washing module (automatic assembly or user-assisted assembly). The sweeping robot 8 then drives the washing module to achieve deep cleaning of the floor.

[0054] (2) Simultaneous sweeping, mopping and washing mode. In this mode, the sweeping robot 8 and the washing module are assembled together (automatic assembly or user-assisted assembly), that is, the sweeping robot 8 and the washing module move at the same time to achieve simultaneous sweeping, mopping and washing operations.

[0055] In the single sweeping and mopping mode, since there is no need to install a floor cleaning module, the weight of the sweeping robot 8 can be reduced, thereby reducing the energy consumption of the sweeping robot 8, increasing the battery life of the sweeping robot 8, and eliminating the need to clean the floor cleaning module, thus reducing the frequency of user maintenance.

[0056] The sweeping and mopping followed by the washing mode allows for dry and wet separation between the robot vacuum 8 and the washing module, keeping the robot vacuum 8's side brushes, dustbin, and other components dry and reducing bacterial growth.

[0057] The simultaneous sweeping, mopping, and washing mode can adapt to scenarios requiring rapid floor cleaning, thus saving cleaning time.

[0058] In some embodiments, such as Figure 3 , Figure 4 and Figure 7As shown, the water spray assembly 4 includes a first water channel 41, a water pump 42, and a spray head 43. The water pump 42 is connected in series with the first water channel 41. One end of the first water channel 41 is connected to the clean water tank 3, and the other end is connected to the spray head 43. The spray head 43 is located on the front side of the roller brush 21. Under the action of the water pump 42, clean water in the clean water tank 3 can be transported to the spray head 43 through the first water channel 41, and then sprayed onto the roller brush 21 through the spray head 43. Since the spray head 43 is located on the front side of the roller brush 21, the clean water can clean the front side of the roller brush 21 and wet the ground in front of the roller brush 21, thereby improving the cleaning effect of the roller brush 21 and avoiding the problem of water stains remaining behind the roller brush 21 after the floor cleaning module cleans the ground.

[0059] like Figure 4 As shown, the first water path 41 includes a first pipe section 411 and a second pipe section 412. The two ends of the first pipe section 411 are connected to the clean water tank 3 and the water inlet of the water pump 42, respectively. The two ends of the second pipe section 412 are connected to the water outlet of the water pump 42 and the spray head 43, respectively.

[0060] Optionally, such as Figure 2 and Figure 3 As shown, the spray head 43 includes multiple water outlets 431, which are arranged at intervals along the axial direction of the roller brush 21. This improves the uniformity of water spraying and ensures that the wettability of the roller brush 21 remains consistent at all positions along its axial direction, which is beneficial to improving the cleaning effect.

[0061] Understandably, each water outlet 431 can be equipped with multiple water outlet micro-holes so that clean water can be dispersed at the water outlet 431 and sprayed evenly onto the roller brush 21 or the ground in front of the roller brush 21.

[0062] For example, there are three water outlets 431, two of which are arranged on both sides of the roller brush 21 along the axial direction, and the other water outlet 431 is arranged in the middle of the roller brush 21.

[0063] Optionally, such as Figure 7 As shown, the water spray assembly 4 also includes a filter 44, which is located inside the clean water tank 3 and connected to the first water channel 41. It is understood that the clean water entering the first water channel 41 is filtered by the filter 44, thereby preventing impurities in the clean water tank 3 from entering the first water channel 41 and the spray head 43. This improves the smoothness of the clean water flow in the water spray assembly 4, reduces the probability of the first water channel 41 and the spray head 43 being clogged by impurities, and improves the reliability of the floor cleaning module.

[0064] In some embodiments, such as Figure 5 , Figure 7 and Figure 8As shown, a partition 12 is provided inside the housing 1, and a clean water tank 3 and a roller brush 21 are respectively arranged on the upper and lower sides of the partition 12. That is, the clean water tank 3 is arranged on the upper side of the partition 12, and the roller brush 21 is arranged on the lower side of the partition 12. The partition 12 can prevent the dirt thrown out by the roller brush 21 during cleaning from splashing onto the clean water tank 3.

[0065] like Figure 7 and Figure 8 As shown, the housing 1 contains a partition 12, a first receiving cavity 131, and a second receiving cavity 132. The first receiving cavity 131 is located above the partition 12, and the second receiving cavity 132 is located below the partition 12. The clean water tank 3 is located in the first receiving cavity 131, and the roller brush 21 is located in the second receiving cavity 132. It can be understood that the partition 12 is used to support and seal the first receiving cavity 131, and the lower end of the second receiving cavity 132 has an opening for the roller brush 21 to contact the ground.

[0066] When the roller brush 21 cleans the floor, it can prevent wastewater from being splashed onto the wall of the clean water tank 3. In other words, the partition 12 can separate the first receiving cavity 131 and the second receiving cavity 132 to prevent wastewater generated during the cleaning of the roller brush 21 from entering the first receiving cavity 131. This makes it easier for users to perform daily maintenance on the floor cleaning module and facilitates wiping.

[0067] Optionally, such as Figure 8 As shown, the second receiving cavity 132 includes a first partition 1321 and a second partition 1322. The second partition 1322 is located above the first partition 1321 and behind the first receiving cavity 131. The roller brush 21 is located in the first partition 1321, and the water pump 42 is located in the second partition 1322. It can be understood that the water pump 42 is located in the second receiving cavity 132 and above the roller brush 21, which allows for a compact arrangement of components within the housing 1 and better space utilization, which is beneficial for the miniaturization design of the floor cleaning module.

[0068] like Figure 8 As shown, the partition 12 has a stepped structure. The partition 12 includes a first stepped plate 121, a vertical plate 123, and a second stepped plate 122. The first stepped plate 121, the vertical plate 123, and the second stepped plate 122 are connected in sequence. The first stepped plate 121 and the second stepped plate 122 are both arranged horizontally. The first stepped plate 121 is located in front of the second stepped plate 122. The height of the second stepped plate 122 is higher than that of the first stepped plate 121. The vertical plate 123, the second stepped plate 122, and the inner wall of the housing 1 together form a second partition 1322. The first partition 1321 is located below the first stepped plate 121 and below the second partition 1322.

[0069] The shape of the clean water tank 3 matches the shape of the first receiving cavity 131, thereby increasing the volume of the clean water tank 3. For example... Figure 7As shown, the cross-section of the housing 1 is rectangular. Since the partition 12 has a stepped structure, the cross-sectional shape of the first receiving cavity 131 is generally L-shaped. Correspondingly, the cross-sectional shape of the water tank 3 is also generally L-shaped, so as to make full use of the space of the first receiving cavity 131 and expand the water storage capacity of the water tank 3.

[0070] In some embodiments, such as Figure 5 and Figure 7 As shown, the floor cleaning module also includes a wastewater tank 5 and a suction assembly 6. The wastewater tank 5 is located inside the housing 1, and the suction assembly 6 is connected to the wastewater tank 5. The suction assembly 6 can generate negative pressure to suck the wastewater on the roller brush 21 into the wastewater tank 5. It can be understood that when the suction assembly 6 is working, it can use the suction force generated by the negative pressure to draw the wastewater on the roller brush 21 into the wastewater tank 5, thereby cleaning the roller brush 21 and improving the overall cleaning effect of the floor cleaning module.

[0071] Optionally, the wastewater tank 5 and the clean water tank 3 are arranged at intervals along the axial direction of the roller brush 21. It can be understood that the wastewater tank 5 and the clean water tank 3 are arranged at intervals in the left-right direction, which can reduce the space occupied by the housing 1 in the front-back direction, that is, reduce the front-back dimension of the housing 1, so as to improve the obstacle avoidance effect when the floor cleaning module moves.

[0072] Specifically, such as Figure 3 and Figure 4 As shown, the suction assembly 6 includes a suction component 61, a second water passage 62, and an air pump 63. The air pump 63 is connected to the sewage chamber of the sewage tank 5. The air pump 63 can generate negative pressure in the sewage chamber. One end of the second water passage 62 is connected to the suction component 61, and the other end of the second water passage 62 is connected to the sewage chamber. The suction component 61 is provided with a suction port 611, which is arranged opposite to the roller brush 21.

[0073] When the suction assembly 6 is working, the air pump 63 can reduce the air pressure in the sewage chamber. Since the second water passage 62 is connected to the sewage chamber and the suction port 611 is opposite to the roller brush 21, the sewage on the roller brush 21 can be sucked into the second water passage 62 by the suction port 611 and enter the sewage chamber, thereby completing the suction work of the suction assembly 6.

[0074] It should be noted that the suction component 61 can abut against the bristles on the roller brush 21, and the suction component 61 can also have a certain gap with the bristles on the roller brush 21. The gap size between the suction component 61 and the roller brush 21 is based on the ability to suction the sewage on the roller brush 21, and this utility model does not limit this.

[0075] Optionally, such as Figure 7As shown, the suction component 61 is located on the rear side of the roller brush 21 and is arranged adjacent to the upper side of the roller brush 21. In this example of the present invention, the spray head 43 is located on the front side of the roller brush 21, and the suction component 61 is located on the rear side of the roller brush 21. This prevents the clean water sprayed from the spray head 43 from being sucked into the wastewater tank 5, and because the suction component 61 is located on the rear side of the roller brush 21, wastewater dripping onto the floor after the roller brush 21 has been cleaned can be avoided, thereby improving the cleaning effect and efficiency of the floor cleaning module.

[0076] In addition, since the suction component 61 is arranged near the upper side of the roller brush 21, when the roller brush 21 rotates, the sewage is easily splashed upward under the action of centrifugal force. At this time, the suction component 61 can more easily absorb the sewage, which helps to improve the cleaning effect of the roller brush 21.

[0077] In one example, such as Figure 3 and Figure 4 As shown, the suction assembly 6 also includes a first air passage 64, which is connected to the sewage chamber. An air pump 63 is located outside the sewage tank 5 and connected in series with the first air passage 64. When the air pump 63 is working, the first air passage 64 can extract air from the sewage chamber to create a negative pressure in the sewage chamber.

[0078] like Figure 4 As shown, the first air passage 64 includes a third pipe section 641 and a fourth pipe section 642. The two ends of the third pipe section 641 are connected to the sewage tank 5 and the air intake end of the air pump 63, respectively. The two ends of the fourth pipe section 642 are connected to the air outlet end of the air pump 63 and the outside atmosphere, respectively.

[0079] Optionally, such as Figure 7 As shown, the suction component 61 has a suction chamber 612. One end of the suction chamber 612 is connected to the suction port 611, and the other end is connected to the second water passage 62. The cross-sectional area of ​​the suction chamber 612 gradually decreases from one end to the other. In other words, the cross-sectional area of ​​the suction chamber 612 gradually decreases from front to back. This facilitates the collection of wastewater from the suction chamber 612 into the wastewater tank 5 via the second water passage 62, thus improving the suction effect of the suction component 61.

[0080] like Figure 7 As shown, the suction port 611 is roughly rectangular, and the length of the suction port 611 is roughly equal to the length of the roller brush 21, so as to ensure that all the sewage in each area of ​​the roller brush 21 along the axis can be sucked into the sewage tank 5.

[0081] In some embodiments, such as Figure 5As shown, both the water pump 42 and the air pump 63 are located inside the housing 1, and are arranged on the same side of the housing 1 in the front-rear direction. Compared with the scheme of arranging the water pump 42 and the air pump 63 on different sides of the housing 1, the space occupied by the water pump 42 and the air pump 63 in the housing 1 can be reduced, which is beneficial to reducing the volume of the housing 1.

[0082] like Figure 5 and Figure 8 As shown, both water pump 42 and air pump 63 are arranged within the second partition 1322, and along the axial direction of the roller brush 21 (e.g., Figure 3 The wastewater tank 5 and the clean water tank 3 are arranged at intervals in the left and right directions. The shapes of the wastewater tank 5 and the clean water tank 3 are matched with the shape of the first receiving cavity 131, thereby increasing the volume of the wastewater tank 5 and the clean water tank 3.

[0083] Optionally, such as Figure 1 and Figure 8 As shown, the housing 1 includes a housing body 14 and a cover 15. The housing body 14 is provided with a first receiving cavity 131. The cover 15 is installed on the housing body 14 and can open and close the opening of the first receiving cavity 131, thereby facilitating the user to take out and put in the clean water tank 3 and the wastewater tank 5.

[0084] like Figure 8 As shown, the shell body 14 has a front wall panel and a rear wall panel. The front wall panel, the rear wall panel, the cover 15, and the partition 12 together define the first receiving cavity 131. The cover 15 is located on the upper side of the shell body 14, that is, the opening of the first receiving cavity 131 is arranged facing upwards, so as to facilitate the user to take out and put in the clean water tank 3 and the wastewater tank 5.

[0085] For example, the cover 15 and the shell body 14 can be connected by a hinge. Alternatively, the cover 15 and the shell body 14 can be detachably connected by a snap-fit ​​mechanism. This application does not specifically limit the connection method between the cover 15 and the shell body 14.

[0086] In some embodiments, such as Figure 6 As shown, the floor cleaning module also includes an electronic control component 7, which includes at least a power supply board 71. The power supply board 71 is located in the first receiving cavity 131 of the housing 1. For example, the power supply board 71 is located at the front side of the first receiving cavity 131, that is, the power supply board 71 is located in the gap between the front wall panel of the housing 1 and the wastewater tank 5 (clean water tank 3). This allows full use of the space in the first receiving cavity 131, making the arrangement of the components inside the housing 1 more compact.

[0087] Optionally, the connecting part 11 is at least one of a plug-in part, a hook-in part, a snap-in part, and a magnetic part.

[0088] In one example, the connecting part 11 is a plug-in connector, meaning that the connecting part 11 and the robot vacuum cleaner 8 are fixed together by a plug-in connection. For example, the plug-in connector is a plug post.

[0089] In another example, the connecting part 11 is a hook. That is, the connecting part 11 and the robot vacuum cleaner 8 are fixed together by hooking. For example, the hook is a hook.

[0090] In another example, the connecting part 11 is a snap-fit ​​connector. That is, the connecting part 11 and the robot vacuum cleaner 8 are fixed together by snap-fit. For example, the snap-fit ​​connector can be a snap block, a snap hook, or a snap ring.

[0091] In another example, the connecting part 11 is a magnetic component. That is, the connecting part 11 and the robot vacuum cleaner 8 are fixed together by magnetic attraction. For example, the magnetic component is a permanent magnet or an electromagnet.

[0092] The number of connecting parts 11 can be one or more. When there are multiple connecting parts 11, the connecting parts 11 can be arbitrarily selected and combined from plug-in parts, hanging parts, snap-fit ​​parts and magnetic parts, and this utility model does not limit them in this regard.

[0093] Optionally, the connecting part 11 has a communication interface (not shown) for communicating with the robotic vacuum cleaner 8. It is understood that the connecting part 11 has two functions: first, it can be mechanically connected to the robotic vacuum cleaner 8, meaning the robotic vacuum cleaner 8 can drive the floor cleaning module to move synchronously through the connecting part 11; second, it can communicate with the robotic vacuum cleaner 8 to control the operation of the roller brush 21 and the water spray assembly 4 in the floor cleaning module. This improves the compactness of the component arrangement, resulting in a more aesthetically pleasing appearance and better overall integrity.

[0094] In other examples, the floor cleaning module also includes a wireless communication module, which is located inside the housing 1 and used for wireless communication with the robotic vacuum cleaner 8. Compared to a plug-in communication scheme between the floor cleaning module and the robotic vacuum cleaner 8, this improves the stability of communication between the two, is less affected by external factors such as mechanical vibration, and is more reliable in operation.

[0095] like Figure 1 As shown, another embodiment of the cleaning device of this utility model includes a floor washing module and a sweeping robot 8. The floor washing module is the floor washing module of this utility model, and the outer side wall of the sweeping robot 8 is provided with a mating part (not shown), which is detachably connected to the connecting part 11.

[0096] According to the cleaning device of this utility model embodiment, the user can selectively assemble the floor washing module and the sweeping robot 8 together or separate them according to the working mode of the cleaning device. When the cleaning device is sweeping alone, the floor washing module and the sweeping robot 8 can be separated, which helps to reduce the energy consumption of the sweeping robot 8 and improve its battery life. When the cleaning device is washing the floor, the floor washing module and the sweeping robot 8 can be assembled together, and the water spraying component 4 sprays clean water from the clean water tank 3 onto the roller brush 21 or the ground to achieve live water cleaning of the roller brush 21, reducing the maintenance frequency of the cleaning device.

[0097] Optionally, the mating part and the connecting part 11 are engaged. For example, one of the mating part and the connecting part 11 is provided with a engaging block, and the other of the mating part and the connecting part 11 is provided with a engaging groove. The engaging block and the engaging groove engage with each other, thereby facilitating the installation and separation of the floor cleaning module and the sweeping robot 8.

[0098] Optionally, the mating part and the connecting part 11 are hooked together. For example, one of the mating part and the connecting part 11 is provided with a hook, and the other of the mating part and the connecting part 11 is provided with a hanging groove. The hook and the hanging groove are hooked together, which facilitates the installation and separation of the floor cleaning module and the sweeping robot 8.

[0099] Optionally, the mating part and the connecting part 11 are magnetically connected. For example, one of the mating part and the connecting part 11 is provided with a first magnetic member, and the other of the mating part and the connecting part 11 is provided with a second magnetic member. The first magnetic member and the second magnetic member attract each other, thereby facilitating the installation and separation of the floor cleaning module and the sweeping robot 8.

[0100] Of course, the floor cleaning module and the sweeping robot 8 can also be connected by fasteners or other detachable methods, and this utility model does not make specific limitations in this regard.

[0101] Another embodiment of the cleaning system of this utility model includes a base station (not shown) and a cleaning device. The cleaning device is the cleaning device of this utility model and can be docked at the base station. For example, the base station has functions such as charging, adding liquid, and dust collection for a sweeping robot 8 or a floor cleaning module.
