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 robotic vacuum cleaners mainly consist of a sweeping module and a mopping module. These modules work together to perform both sweeping and mopping functions. However, because the sweeping and mopping modules are integrated into the entire machine and cannot be separated, the cleaning equipment needs to carry the mopping 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, wherein the housing has a recess on one side along the horizontal direction for accommodating at least part of a sweeping robot, and a connecting part on the housing for mounting to the sweeping robot and being detachable from the sweeping robot; a roller brush mounted on the lower side of the housing; a clean water tank and a water supply assembly, wherein the clean water tank is disposed inside the housing, and the water supply 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 working 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 supply component sprays clean water from the clean 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 addition, since the recess can accommodate at least part of the robot vacuum, when the floor cleaning module and the robot vacuum are assembled together, the space occupied by the floor cleaning module and the robot vacuum can be reduced, making the overall structure of the floor cleaning module and the robot vacuum more compact.

[0010] In some embodiments, the recess has a top wall surface and a side wall surface, the top wall surface being parallel to the horizontal direction and the side wall surface being orthogonal to the horizontal direction, and the connecting portion being disposed on at least one of the top wall surface and the side wall surface.

[0011] In some embodiments, the top wall and the side wall form a clearance cavity that extends through the housing along the axial direction of the brush.

[0012] In some embodiments, the connecting part is at least one of a plug, a hook, a snap-fit, and a magnetic connector.

[0013] In some embodiments, the connecting part has a communication interface for communicating with the robot vacuum cleaner; or, the floor cleaning module further includes a wireless communication module, which is disposed inside the housing and is used for wirelessly communicating with the robot vacuum cleaner.

[0014] In some embodiments, the floor cleaning module further includes an electronic control component disposed within the housing and located on the side of the clean water tank opposite to the recess.

[0015] In some embodiments, the water supply 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 clear water tank, and the other end of the first water path is connected to the spray head. The spray head is located in front of the roller brush.

[0016] 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 in communication with the wastewater tank. The suction assembly can generate negative pressure to suck the wastewater on the roller brush into the wastewater tank.

[0017] Another embodiment of the cleaning device of the present invention includes a floor washing module, which is the floor washing module described in any one of the embodiments of the present invention; a sweeping robot, wherein the outer side wall of the sweeping robot is provided with a mating part, at least part of the sweeping robot is located in the recessed part, and the mating part is detachably connected to the connecting part.

[0018] According to embodiments of this utility model, the cleaning device 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 according to the working mode of the cleaning device. When the cleaning device 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 device is washing the floor, the floor-washing module and the robotic vacuum cleaner can be assembled together. The water supply component sprays clean water from the clean 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. Furthermore, since the recessed part can accommodate at least part of the robotic vacuum cleaner, when the floor-washing module and the robotic vacuum cleaner are assembled together, the space occupied by the floor-washing module and the robotic vacuum cleaner can be reduced, making the overall structure of the cleaning device more compact.

[0019] 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.

[0020] The cleaning system according to an embodiment of this utility model can be installed on 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 according to the working 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. The water supply component sprays clean water from the clean 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. Furthermore, since the recessed part can accommodate at least part of the robotic vacuum cleaner, when the floor-washing module and the robotic vacuum cleaner are assembled together, the space occupied by the floor-washing module and the robotic vacuum cleaner can be reduced, making the overall structure of the cleaning equipment more compact.

[0037] 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.

[0038] The following is a reference appendix. Figures 1 to 7 This invention describes a floor cleaning module, cleaning equipment, and cleaning system according to embodiments of the present invention.

[0039] like Figures 1 to 7 As shown, the floor cleaning module of this utility model embodiment includes: a shell 1, a roller brush assembly 2, a clean water tank 3, and a water supply assembly 4.

[0040] The outer casing 1 has a recess 11 on one side along the horizontal direction. The recess 11 is used to accommodate at least part of the sweeping robot 8. The outer casing 1 has a connecting part 12, which is used to be installed on the 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 outer casing 1. The clean water tank 3 is located inside the outer casing 1. The water supply 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.

[0041] According to the embodiments of this utility model, the floor cleaning module can be installed onto the sweeping robot 8 via the connecting part 12. Since the connecting part 12 is detachable from the sweeping robot 8, the user can selectively assemble or detach the floor cleaning module and the sweeping robot 8 according to the working mode of the cleaning equipment. In other words, the floor cleaning module can be freely assembled onto the sweeping robot 8.

[0042] 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 supply 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.

[0043] In addition, since the recess 11 can accommodate at least part of the sweeping robot 8, when the floor cleaning module and the sweeping robot 8 are assembled together, the space occupied by the floor cleaning module and the sweeping robot 8 can be reduced, making the overall structure of the floor cleaning module and the sweeping robot 8 more compact.

[0044] 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 supply component 4 can spray water towards the roller brush 21, and the water supply component 4 can also spray water towards the ground in front of the roller brush 21 to perform deep cleaning of the ground.

[0045] 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 outer casing 1, thereby improving the floor cleaning effect of the roller brush 21.

[0046] In other examples, the floor cleaning module may not require a drive motor to rotate the roller brush 21.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] The cleaning device of this utility model has at least the following functions:

[0051] (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.

[0052] (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) operations. After the sweeping robot 8 finishes sweeping and mopping, it 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.

[0053] (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.

[0054] 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.

[0055] 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.

[0056] The simultaneous sweeping, mopping, and washing mode can adapt to scenarios requiring rapid floor cleaning, thus saving cleaning time.

[0057] Optionally, such as Figure 1 , Figure 6 and Figure 7 As shown, the recess 11 is provided on the front side of the outer casing 1, and the connecting part 12 is provided on the recess 11. It should be noted that the forward direction of the floor cleaning module is the front side of the outer casing 1, and the opposite direction of the forward direction of the floor cleaning module is the rear side of the outer casing 1.

[0058] Since the recess 11 is located on the front side of the outer shell 1, the rear end of the robot vacuum 8 can extend into (embed) the space enclosed by the recess, that is, the rear end of the robot vacuum 8 matches the front end of the outer shell 1. This facilitates the movement of the cleaning module by the robot vacuum 8 and improves obstacle avoidance. Furthermore, since the connecting part 12 is located on the recess 11, the connection structure between the robot vacuum 8 and the cleaning module is more compact and occupies less space.

[0059] For example, the recess 11 is arranged near the lower side of the outer casing 1 so that the recess 11 matches the shape of the robot vacuum cleaner 8.

[0060] Optionally, such as Figure 1 and Figure 4 As shown, the recessed portion 11 has a top wall surface 111 and a side wall surface 112. The top wall surface 111 is parallel to the horizontal direction, and the side wall surface 112 is orthogonal to the horizontal direction. The connecting portion 12 is provided on at least one of the top wall surface 111 and the side wall surface 112. It can be understood that the top wall surface 111 is substantially parallel to the upper end surface of the sweeping robot 8, and the side wall surface 112 is arranged opposite to the outer peripheral wall of the sweeping robot 8.

[0061] The recessed portion 11 of the floor cleaning module in this embodiment of the utility model can accommodate part of the sweeping robot, making the overall structure of the sweeping robot 8 and the floor cleaning module more compact and occupying less space. Furthermore, the connecting portion 12 is provided on the top wall surface 111 or the side wall surface 112 of the recessed portion 11, which can hide the connection structure between the sweeping robot 8 and the floor cleaning module. It also makes full use of the space inside the recessed portion 11, improves the rationality of the arrangement of cleaning equipment components, and has good overall integrity.

[0062] For example, the connecting part 12 may be provided only on the top wall surface 111. Alternatively, the connecting part 12 may be provided only on the side wall surface 112.

[0063] For example, one connecting part 12 is provided on the top wall surface 111 of the recessed part 11, and another connecting part 12 is provided on the side wall surface 112 of the recessed part 11, thereby improving the reliability of the connection between the sweeping robot 8 and the floor cleaning module.

[0064] In other examples, the recessed portion 11 also has a bottom wall surface (not shown), and the connecting portion 12 is provided on the bottom wall surface. When the sweeping robot 8 docks with the floor cleaning module, the connecting portion 12 on the bottom wall surface can be connected to the lower end surface of the sweeping robot.

[0065] Optionally, such as Figure 1 and Figure 4 As shown, the top wall 111 and the side wall 112 form an avoidance cavity 113. The avoidance cavity 113 extends through the outer shell 1 along the axial direction of the roller brush 21, so that the sweeping robot 8 can enter and exit the avoidance cavity 113 formed by the recess 11 in multiple directions, which improves the flexibility of the sweeping robot 8 when assembling with the floor cleaning module.

[0066] In the example of this application, the clearance cavity 113 formed by the recess 11 is generally rectangular and extends along the left and right direction of the outer shell 1 and penetrates the outer shell 1, so that the sweeping robot 8 can enter and exit the clearance cavity 113 formed by the recess 11 in multiple directions (e.g., from front to back, from left to right, and from right to left), which improves the flexibility of assembling the sweeping robot 8 with the floor cleaning module.

[0067] Optionally, the connecting part 12 is at least one of a plug-in part, a hook-in part, a snap-in part, and a magnetic part.

[0068] In one example, the connecting part 12 is a plug-in connector, meaning that the connecting part 12 and the robot vacuum cleaner 8 are fixed together by a plug-in connection. For example, the plug-in connector is a plug post.

[0069] In another example, the connecting part 12 is a hook. That is, the connecting part 12 and the robot vacuum cleaner 8 are fixed together by hooking. For example, the hook is a hook.

[0070] In another example, the connecting part 12 is a snap-fit ​​component. That is, the connecting part 12 and the robot vacuum cleaner 8 are fixed together by snap-fit. For example, the snap-fit ​​component can be a snap block, a snap hook, or a snap ring.

[0071] In another example, the connecting part 12 is a magnetic component. That is, the connecting part 12 and the robot vacuum cleaner 8 are fixed together by magnetic attraction. For example, the magnetic component is a permanent magnet or an electromagnet.

[0072] The number of connecting parts 12 can be one or more. When there are multiple connecting parts 12, the connecting parts 12 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.

[0073] Optionally, the connecting part 12 has a communication interface (not shown) for communicating with the robotic vacuum cleaner 8. It is understood that the connecting part 12 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 12; second, it can communicate with the robotic vacuum cleaner 8 to control the operation of the roller brush 21 and water supply component 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.

[0074] In other examples, the floor cleaning module also includes a wireless communication module (not shown), which is located inside the housing 1 and is used for wireless communication with the robot vacuum cleaner 8. Compared to a plug-in communication scheme between the floor cleaning module and the robot vacuum cleaner 8, this method improves the stability of communication between the two, is less affected by external factors such as mechanical vibration, and is more reliable in operation.

[0075] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, the water supply component 4 includes a first water passage 41, a water pump 42, and a spray head 43. The water pump 42 is connected in series with the first water passage 41. One end of the first water passage 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, the clean water in the clean water tank 3 can be transported to the spray head 43 through the first water passage 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.

[0076] like Figure 5 As shown, the first water passage 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 clear water tank 3 and the inlet of the water pump 42, respectively. The two ends of the second pipe section 412 are connected to the outlet of the water pump 42 and the spray head 43, respectively. Optionally, 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.

[0077] 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.

[0078] 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.

[0079] Optionally, such as Figure 6 As shown, the water supply assembly 4 also includes a filter 44, which is located inside the clean water tank 3 and connected to the first water path 41. It is understood that the clean water entering the first water path 41 is filtered by the filter 44, thereby preventing impurities in the clean water tank 3 from entering the first water path 41 and the spray head 43. This improves the smoothness of the clean water flow in the water supply assembly 4, reduces the probability of the first water path 41 and the spray head 43 being clogged by impurities, and improves the reliability of the floor cleaning module.

[0080] In some embodiments, such as Figure 4 and Figure 6 As shown, the outer casing 1 has a receiving cavity 13, which includes a first partition 131 and a second partition 132. The second partition 132 is located in front of the first partition 131 and above the recess 11. At least part of the clear water tank 3 and / or at least part of the water pump 42 are located in the second partition 132. This allows for full utilization of the space above the recess 11, making the arrangement of components inside the outer casing 1 more compact and reducing the space occupied by the outer casing 1.

[0081] like Figures 4 to 6 As shown, the first partition 131 can accommodate most of the clean water tank 3, and the second partition 132 can accommodate a small portion of the clean water tank 3. Specifically, the clean water tank 3 includes a first extension tank 31 and a first water tank body 32. The first water tank body 32 is located in the first partition 131, the first extension tank 31 is located in front of the first water tank body 32 and within the second partition 132, and the water pump 42 is located within the second partition 132, and the water pump 42 is located in the lower area of ​​the first extension tank 31.

[0082] like Figure 6 As shown, the first extension box 31 and the first water tank body 32 are connected, and the connection structure is generally L-shaped. A partition 16 is provided at the bottom of the receiving cavity 13, located between the clean water tank 3 and the roller brush 21 to separate the roller brush 21 from the clean water tank 3. When the roller brush 21 cleans the floor, it prevents wastewater on the roller brush 21 from being splashed into the receiving cavity 13 of the clean water tank 3, facilitating daily maintenance of the floor cleaning module and making cleaning easier.

[0083] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the floor cleaning module also includes a wastewater tank 5 and a suction component 6. The wastewater tank 5 is located inside the outer casing 1, and the suction component 6 is connected to the wastewater tank 5. The suction component 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 component 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.

[0084] 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 outer shell 1 in the front-back direction, that is, reduce the size of the outer shell 1 in the front-back direction, so as to improve the obstacle avoidance effect when the floor cleaning module moves.

[0085] Specifically, such as Figure 7 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.

[0086] 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.

[0087] 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.

[0088] Optionally, such as Figure 6 and Figure 7 As 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.

[0089] 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.

[0090] Optionally, such as Figure 5 As shown, the water pump 42 and the air pump 63 are arranged on the same side in the front-rear direction of the housing 1. 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.

[0091] For example, such as Figure 7 As shown, at least part of the sewage tank 5 and / or at least part of the air pump 63 are located within the second partition 132. This allows for full utilization of the space above the recess 11, enabling a more compact arrangement of components within the housing 1 and reducing the space occupied by the housing 1.

[0092] like Figure 5 and Figure 7 As shown, the first partition 131 can accommodate most of the sewage tank 5, and the second partition 132 can accommodate a smaller portion of the sewage tank 5. Specifically, the sewage tank 5 includes a second extension box 51 and a second tank body 52. ​​The second tank body 52 is located in the first partition 131, the second extension box 51 is located in front of the first tank body 52 and within the second partition 132, and the air pump 63 is located within the second partition 132, specifically in the lower region of the second extension box 51. Figure 7 As shown, the second extension box 51 and the second water tank body 52 are connected, and the connection structure is roughly L-shaped.

[0093] In one example, such as Figure 7 As shown, the suction assembly 6 also includes a first air passage 64, which is connected to the sewage chamber of the sewage tank 5. 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.

[0094] like Figure 5 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. Optionally, as... Figure 6 and Figure 7As 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.

[0095] 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.

[0096] In some embodiments, such as Figure 6 and Figure 7 As shown, the floor cleaning module also includes an electronic control component 7, which is located inside the housing 1 and situated on the side of the clean water tank 3 opposite to the recess 11. This allows for full utilization of the space in the receiving cavity 13, resulting in a more compact arrangement of components within the housing 1. Figure 6 As shown, the electronic control assembly 7 and the recess 11 are respectively arranged on the front and rear sides of the housing 1. The electronic control assembly 7 includes at least a power board 71. For example, the power board 71 is arranged at the rear side of the receiving cavity 13, that is, the power board 71 is located in the gap between the rear wall of the housing 1 and the sewage tank 5 (clean water tank 3), thereby making full use of the space of the receiving cavity 13 and making the arrangement of the components inside the housing 1 more compact.

[0097] Optionally, such as Figure 1 and Figure 4 As shown, the outer shell 1 includes a shell body 14 and a cover 15. The shell body 14 has a receiving cavity 13 inside. The cover 15 is installed on the shell body 14 and can open and close the opening of the receiving cavity 13.

[0098] like Figure 4 As shown, the shell body 14 has a front wall panel and a rear wall panel, which together define the receiving cavity 13. The cover 15 is located on the upper side of the shell body 14, that is, the opening of the receiving cavity 13 is arranged facing upwards, so as to facilitate the user to take out and put in the clean water tank 3 and the sewage tank 5.

[0099] 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.

[0100] like Figure 1As 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 12.

[0101] According to an embodiment of this utility model, the cleaning device can be installed on a sweeping robot 8 via the connecting part 12. Since the connecting part 12 is detachable from the sweeping robot 8, the user can selectively assemble the floor-washing module and the sweeping robot 8 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 8 can be separated, which helps 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 supply component 4 sprays clean water from the clean water tank 3 onto the roller brush 21 or the floor to achieve clean water cleaning of the roller brush 21, reducing the maintenance frequency of the floor-washing module.

[0102] In addition, since the recess 11 can accommodate at least part of the sweeping robot 8, when the floor cleaning module and the sweeping robot 8 are assembled together, the space occupied by the floor cleaning module and the sweeping robot 8 can be reduced, making the overall structure of the cleaning equipment more compact.

[0103] Optionally, the mating part (not shown) engages with the connecting part 12. For example, one of the mating part and the connecting part 12 is provided with a snap-fit ​​block, and the other of the mating part and the connecting part 12 is provided with a snap-fit ​​groove. The snap-fit ​​block and the snap-fit ​​groove engage with each other, thereby facilitating the installation and separation of the floor cleaning module and the sweeping robot 8.

[0104] Optionally, the mating part and the connecting part 12 are hooked together. For example, one of the mating part and the connecting part 12 is provided with a hook, and the other of the mating part and the connecting part 12 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.

[0105] Optionally, the mating part and the connecting part 12 are magnetically connected. For example, one of the mating part and the connecting part 12 is provided with a first magnetic member, and the other of the mating part and the connecting part 12 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.

[0106] 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.

[0107] 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.
