Description

Technical Field

[0001] The present application relates to the technical field of intelligent cleaning devices, and particularly to a cleaning module, a cleaning robot, and a cleaning system. Background Art

[0002] A cleaning robot is a type of intelligent device that can automatically perform cleaning tasks on behalf of people. Its appearance not only liberates people's hands, reduces the labor intensity of people's cleaning operations, but also can achieve better cleaning effects and higher cleaning operation speeds. Therefore, it is deeply favored by consumers.

[0003] Compared with traditional cleaning robots that only have a sweeping function, cleaning robots with a combined function of mopping and sweeping are more popular in the market because they can achieve better cleaning effects. The component that performs the mopping function on a cleaning robot is a roller mop module, which is usually equipped on a floor sweeper. After completing a ground cleaning operation and when the floor sweeper returns to the workstation, the cleaning mechanism will automatically clean the mop to remove dirt such as dust and hair adhering to the mop. However, in fact, there are other functional components in the floor sweeper that cooperate with the roller mop, and these functional components are also prone to adhering to dirt. Therefore, simply cleaning the mop by the cleaning mechanism is not sufficient to ensure that the mop is thoroughly cleaned. Therefore, people need to regularly disassemble the roller mop module for manual deep cleaning, which is time-consuming and laborious and has a poor user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide a cleaning module, a cleaning robot, and a cleaning system for the problem that the mop cannot be thoroughly and effectively cleaned, resulting in time-consuming and laborious manual cleaning and a poor user experience.

[0005] On the one hand, the present application provides a cleaning module, which includes:

[0006] A frame;

[0007] A cleaning component, the cleaning component is rotatably connected to the frame, and the cleaning component has a lifted position and a lowered position that can be switched to each other. The cleaning component includes a cleaning roller and a water scraping member that are cooperatively installed;

[0008] A linkage member, one end of the linkage member is rotatably connected to the frame; and,

[0009] A cleaning pipe group, the cleaning pipe group is rotatably connected to the cleaning component, and the cleaning pipe group is rotatably connected to the other end of the linkage member. The cleaning pipe group is provided with a water spraying part;

[0010] When the cleaning assembly is in the lowered position, the water spraying part is arranged towards the cleaning roller; when the cleaning assembly is switched to the lifted position, the linkage synchronously drives the cleaning pipe group to rotate relative to the cleaning assembly so that the water spraying part is switched to face the wiper.

[0011] The cleaning module of the above solution is applied to a cleaning robot. When the cleaning robot moves in the area to be cleaned, the water spraying part of the cleaning pipe group is arranged towards the cleaning roller of the cleaning assembly in the lowered position, and the water spraying part sprays water on the cleaning roller to wet the cleaning roller, so as to meet the requirement that the cleaning roller completes the cleaning and mopping treatment of the ground in the area to be cleaned; when the cleaning operation is over and the cleaning robot returns to the workstation, the cleaning pipe group can continue to spray water on the cleaning roller to complete the self-cleaning treatment of the cleaning roller. After that, the cleaning assembly moves upward under the drive of the lifting mechanism, so as to lift the cleaning assembly to rotate upward relative to the frame and enter the lifted position. During this process, the linkage will also rotate relative to the frame synchronously, so that the linkage can push the cleaning pipe group to rotate a preset angle relative to the cleaning assembly, so that the water spraying part is switched to face the wiper, and the water sprayed from the water spraying part can clean the dirt adhered to the wiper, thus preventing the wiper from causing secondary pollution to the cleaned cleaning roller. In this way, the in-depth cleaning of the cleaning module can be completed, ensuring that the cleaning assembly is thoroughly cleaned. In this way, it is no longer necessary for people to regularly disassemble the cleaning module and manually deeply clean the above components, avoiding the consumption of manpower and time caused by people's frequent installation and disassembly operations, and helping to improve people's use experience.

[0039] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0040] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0041] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0042] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.

[0044] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation manner.

[0045] In the existing related technologies, when a floor sweeper performs a cleaning operation, the cleaning mechanism will automatically clean the mop to remove dirt such as sewage, dust, and hair adhering to the mop. However, in fact, there are other functional components in the floor sweeper that cooperate with the roller mop, and these functional components are also prone to adhering to dirt and easily soiling the mop. Therefore, simply cleaning the mop by the cleaning mechanism is actually not sufficient to ensure that the mop is thoroughly cleaned, and people need to regularly disassemble the roller mop module for manual deep cleaning, which is time-consuming and laborious and has a poor user experience.

[0046] To address this problem, this application proposes a cleaning system that can be applied to automatic cleaning operations in venues such as homes, offices, and stadiums, replacing the traditional manual cleaning operation method, and having the effects of improving quality, increasing efficiency, and reducing costs. Specifically, the cleaning system includes a workstation and a cleaning robot.

[0047] The workstation is used to accommodate the cleaning robot and provide services for the cleaning robot to meet various needs of the cleaning robot. For example, the workstation is provided with an accommodation cabin. When in a non-working state (such as standby or shutdown), the cleaning robot returns to the accommodation cabin. At this time, the cleaning robot is integrated with the workstation, which is more conducive to centralized management and reduces the occupation of site space at the same time.

[0048] In addition, the cleaning robot is also used to return to the workstation to complete the cleaning operation. For example, the workstation is equipped with a cleaning mechanism, and the cleaning mechanism can clean the dirty components of the cleaning robot that returns to the accommodation cabin. Further, the workstation is also equipped with a charging mechanism, a sterilization mechanism, a drying mechanism, etc., so as to meet the needs of the cleaning robot for power supply and endurance, sterilization and disinfection, etc., and greatly improve the performance of the cleaning robot.

[0049] In this application, the cleaning robot can specifically be a floor sweeper, and the floor sweeper includes a cleaning module 100. In addition to having the basic function of cleaning dust and other impurities on the ground, the cleaning module 100 also has functions such as mopping and even drying the ground, so as to meet the different cleaning needs of people or different sites.

[0050] Refer to Figure 1 and Figure 2 , a cleaning module 100 shown in an embodiment of this application, includes a frame 10, a cleaning component 20, a linkage 40, and a cleaning pipe group 50.

[0051] Among them, the frame 10 is used to be connected and fixed to the main structure (such as the housing) of the cleaning robot, and plays a role in loading and fixing components such as the cleaning component 20, the linkage 40, and the cleaning pipe group 50.

[0052] Please continue to refer to Figure 3 and Figure 4 , the cleaning component 20 is rotatably connected to the frame 10, and the cleaning component 20 has a lifted position (such as Figure 4 shown) and a lowered position (such as Figure 3 shown) that can be switched to each other. The cleaning component 20 includes a cleaning roller 21 and a wiper 22 that are installed in cooperation.

[0053] Among them, the cleaning roller 21 and the wiper 22 can be arranged opposite to and in contact with each other, and the wiper 22 can scrape the sewage on the cleaning roller 21 and collect it, so as to maintain the cleaning effect of the cleaning roller 21.

[0054] It can be understood that when the cleaning component 20 is in the lowered position, at this time, the cleaning roller 21 can normally contact the surface to be cleaned, so as to perform a cleaning operation on the surface to be cleaned, such as Figure 3As shown in the figure. For example, when the cleaning roller 21 rotates in a dry state, in cooperation with the negative pressure dust suction mechanism on the cleaning robot, it can suck dust and other impurities on the surface to be cleaned into the dust collection box of the cleaning robot, thereby achieving the purpose of cleaning the surface to be cleaned. When the cleaning roller 21 rotates in a wet state, it can wash and mop the surface to be cleaned.

[0055] It can be understood that when the cleaning assembly 20 is in the lifted position, the cleaning roller 21 is spaced from the surface to be cleaned and cannot contact the surface to be cleaned.

[0056] Furthermore, in order to realize the mutual switching of the cleaning assembly 20 between the lifted position and the lowered position, the cleaning robot further includes a lifting mechanism. The lifting mechanism lifts and lowers the cleaning assembly 20, so as to realize the mutual switching of the cleaning assembly 20 between the lifted position and the lowered position, and further enable the cleaning roller 21 to be spaced from the surface to be cleaned or normally contact the surface to be cleaned.

[0057] Among them, the lifting mechanism can be any one of an electric push rod, a telescopic rod mechanism, etc., and can be specifically selected according to actual needs.

[0058] In one embodiment, the lifting mechanism includes a lifting link 30 connected to the cleaning assembly 20. The lifting link 30 provides an upward lifting force and a downward release force for the cleaning assembly 20, so as to lift the cleaning roller 21 to be spaced from the surface to be cleaned or lower the cleaning roller 21 to normally contact the surface to be cleaned.

[0059] In one embodiment, the lifting link 30 is rotatably connected to the cleaning assembly 20, and the lifting link 30 is used to transmit a driving force to drive the cleaning assembly 20 to switch between the lifted position and the lowered position.

[0060] Among them, one end of the linkage member 40 is rotatably connected to the frame 10 by means of a rotating shaft, etc., the cleaning pipe group 50 is rotatably connected to the cleaning assembly 20 by means of a hinge, etc., and the cleaning pipe group 50 is rotatably connected to the other end of the linkage member 40 by means of a hinge, etc. And, the cleaning pipe group 50 is provided with a water spraying part 51.

[0061] Among them, when the cleaning assembly 20 is in the lowered position, the water spraying part 51 is arranged facing the cleaning roller 21.

[0062] During the cleaning operation, the water spraying part 51 is arranged facing the cleaning roller 21, and a cleaning liquid such as water is sprayed onto the cleaning roller 21 through the water spraying part 51 to wet the cleaning roller 21, so that the cleaning roller 21 can not only rotate to scrub the ground, but also further realize washing and mopping the ground, and thoroughly remove stubborn stains or residual dust adhered to the ground.

[0063] When the cleaning component 20 switches to the lifting position, the linkage 40 synchronously drives the cleaning pipe group 50 to rotate a preset angle relative to the cleaning component 20, so that the water spraying part 51 switches to face the wiper 22.

[0064] It should be noted that the water spraying part 51 facing the wiper 22 can be that the water spraying part 51 completely faces the wiper 22, or part of it faces the wiper 22; when part of the water spraying part 51 faces the wiper 22, part of the sprayed water can clean the wiper 22 and the other part can clean the cleaning roller 21, making the cleaning effect more comprehensive.

[0065] In summary, implementing the technical solution of this embodiment will at least have the following beneficial effects: The cleaning module 100 of the above solution is applied to a cleaning robot. When the cleaning robot moves in the area to be cleaned, the water spraying part 51 of the cleaning pipe group 50 is arranged to face the cleaning roller 21 of the cleaning component 20 in the lowered position, and the water spraying part 51 sprays water on the cleaning roller 21 to wet the cleaning roller 21, so as to meet the requirement that the cleaning roller 21 completes the cleaning and mopping treatment of the surface to be cleaned of the area to be cleaned; when the cleaning operation is over and the cleaning robot returns to the workstation, the cleaning pipe group 50 can also continue to spray water on the cleaning roller 21 to complete the self-cleaning treatment of the cleaning roller 21. After that, driven by the lifting mechanism, the cleaning component 20 is lifted to rotate upward relative to the frame 10 and switches to the lifting position. During this process, the linkage 40 will also rotate synchronously relative to the frame 10, so that the linkage 40 can push the cleaning pipe group 50 to rotate a preset angle (such as 15°, 17°, etc.) relative to the cleaning component 20, so that the water spraying part 51 switches to face the wiper 22, and the water sprayed from the water spraying part 51 cleans the dirt adhered to the wiper 22, thus preventing the wiper 22 from causing secondary pollution to the cleaned cleaning roller 21. Thus, the deep cleaning of the cleaning module 100 can be completed, ensuring that the cleaning component 20 is thoroughly cleaned. In this way, it is no longer necessary for people to regularly disassemble the cleaning module 100 and rely on manual deep cleaning of the above components, avoiding the waste of manpower and time caused by people's frequent installation and disassembly operations, and helping to improve people's use experience.

[0066] Among them, the linkage 40 can be in the form of a connecting arm such as a rocker arm or a swing arm, or in the form of a linkage mechanism, as long as it meets the requirement that when the cleaning component 20 switches to the lifting position, the linkage 40 can synchronously push the cleaning pipe group 50 to rotate relative to the cleaning component 20, so that the water spraying part 51 switches to face the wiper 22 to clean the dirt adhered to the wiper 22.

[0067] Please continue to refer to Figure 1 , Figure 3 and Figure 4, on the basis of the above embodiments, the frame 10 includes a main rod 11, a first connecting rod 12 and a second connecting rod 13. The first connecting rod 12 and the second connecting rod 13 are arranged at intervals along the length direction of the main rod 11. Among them, the first connecting rod 12 and the second connecting rod 13 can be arranged parallel to each other. One end of the first connecting rod 12 is fixedly connected to one end of the main rod 11 in the length direction, and the other end of the first connecting rod 12 can be rotatably connected to the cleaning assembly 20 through a first rotating shaft 14. One end of the second connecting rod 13 is fixedly connected to the other end of the main rod 11 in the length direction, and the other end of the second connecting rod 13 can be rotatably connected to one end of the linkage 40 through a second rotating shaft 15.

[0068] Among them, along the height direction, the length of the second connecting rod 13 is less than the length of the first connecting rod 12.

[0069] For example, when the cleaning assembly 20 is in the lowered position, the second connecting rod 13 and the first connecting rod 12 are arranged in the height direction, and the height of the end of the second connecting rod 13 away from the main rod 11 from the ground is greater than the height of the end of the first connecting rod 12 away from the main rod 11 from the ground.

[0070] Since the first connecting rod 12 and the second connecting rod 13 are respectively located at both ends of the main rod 11 in the length direction, the rotational connection between the first connecting rod 12 and the cleaning assembly 20 and the rotational connection between the second connecting rod 13 and the linkage 40 are separated by a sufficient installation distance, thus avoiding interference problems when the cleaning assembly 20 and the linkage 40 rotate.

[0071] And because the length of the second connecting rod 13 is shorter than that of the first connecting rod 12, and both are vertically arranged in the installation and use state, the end of the second connecting rod 13 away from the main rod 11 is closer to the cleaning pipe group 50, so that the length of the linkage 40 can be set shorter to meet the need of connecting the second connecting rod 13 and the cleaning pipe group 50. And precisely because the length of the linkage 40 is shorter, when the lifting mechanism pulls up the cleaning assembly 20 to rotate a small angle, the linkage 40 can synchronously drive the cleaning pipe group 50 to rotate a small preset angle relative to the cleaning assembly 20, realizing the switching of the water spraying part 51 to face the wiper 22, making the switching response speed of the whole mechanism faster and helping to improve the self-cleaning efficiency of the cleaning module 100.

[0072] Please refer to Figure 3, in one embodiment, when the cleaning assembly 20 is in the lowered position, the central axis of the cleaning roller 21 in the vertical direction passes through the water spraying part 51 or the water spraying part 51 is located on one side of the central axis closer to the wiper 22. Considering that the lifting distance of the cleaning assembly 20 is short, this arrangement can ensure that when the cleaning assembly 20 is lifted a short distance and in the lifted position, the water spraying part 51 can rotate a small angle to accurately face the wiper 22 without being blocked or interfered by the cleaning roller 21.

[0073] Please continue to refer to Figure 1 , Figures 5 to 8 , in some embodiments, the cleaning pipe group 50 includes a self-cleaning water pipe 52 and a water pipe joint 53. The self-cleaning water pipe 52 is rotatably installed in the cleaning assembly 20. The self-cleaning water pipe 52 is provided with a water spraying part 51, and the self-cleaning water pipe 52 is further provided with a water inlet 521. The water pipe joint 53 is connected to the water inlet 521 and is located outside the cleaning assembly 20. The water pipe joint 53 includes a connecting arm 531, and the connecting arm 531 is rotatably connected to the other end of the linkage 40.

[0074] The water pipe joint 53 is installed outside the cleaning assembly 20, so that it is more convenient to connect with the water supply pipe, enabling the cleaning water (i.e., tap water or other types of cleaning water) to enter the water inlet 521 through the water pipe joint 53 and then flow into the self-cleaning water pipe 52, and finally spray out from the water spraying part 51 to clean the cleaning roller 21 or the wiper 22. The linkage 40 is rotatably connected to the connecting arm 531, making it easier to synchronously push the water pipe joint 53 to drive the self-cleaning water pipe 52 to rotate while rotating itself, so as to adjust the spraying direction of the water spraying part 51.

[0075] Furthermore, the water pipe joint 53 further includes a pipe body 532 and a water pipe interface 533. The connecting arm 531 and the water pipe interface 533 are respectively installed on the pipe body 532, and the connecting arm 531 and the water pipe interface 533 are distributed at an angle, so as to avoid interference with the linkage 40. In addition, the pipe body 532 is provided with a water passing hole 532a, and the water pipe interface 533 is communicated with the water inlet 521 through the water passing hole 532a.

[0076] The water pipe interface 533 is specifically cylindrical with both ends penetrating and hollow inside. The water pipe interface 533 is integrally or detachably connected to the pipe body 532. The water pipe interface 533 is used for directly plugging and fixing with the water supply pipe, and the installation method is simple. Further, in order to prevent the water supply pipe from easily falling off the water pipe interface 533, the outer peripheral wall of the water pipe interface 533 is provided with an anti-slip texture structure to increase the friction with the water supply pipe. For example, in this embodiment, the anti-slip texture structure is specifically a plurality of anti-slip protrusions arranged at intervals along the axial direction of the water pipe interface 533.

[0077] During installation, inserting the water inlet port 521 into the water passing hole 532a can connect the water pipe interface 533, the water passing hole 532a, and the water inlet port 521, which helps to shorten the length of the cleaning water flow path and supply water to the self-cleaning water pipe 52 more efficiently.

[0078] Please continue to refer to Figure 6 In addition, in order to prevent leakage at the insertion part of the water inlet port 521 and the water passing hole 532a, a sealing ring 54 is installed on the outside of the water inlet port 521 or inside the water passing hole 532a, and the sealing ring 54 can improve the sealing performance.

[0079] Please continue to refer to Figure 6 and Figure 8 Based on the above embodiments, a rotation prevention notch 521a is recessed in the pipe end wall of the water inlet port 521, and a rotation prevention protrusion 532b is provided on the hole wall of the water passing hole 532a. The rotation prevention notch 521a and the rotation prevention protrusion 532b are engaged to assemble and fix the self-cleaning water pipe 52 and the water pipe joint 53.

[0080] Alternatively, as an alternative to the above embodiments, a rotation prevention protrusion 532b is provided on the outer pipe wall of the water inlet port 521, and a rotation prevention groove is recessed in the hole wall of the water passing hole 532a. The rotation prevention protrusion 532b is engaged in the rotation prevention groove to assemble and fix the self-cleaning water pipe 52 and the water pipe joint 53.

[0081] Taking the pipe end wall of the water inlet port 521 having a rotation prevention notch 521a and the hole wall of the water passing hole 532a having a rotation prevention protrusion 532b as an example, after the water inlet port 521 is inserted into the water passing hole 532a, the rotation prevention protrusion 532b automatically snaps into the rotation prevention notch 521a, thereby forming an installation limit for the self-cleaning water pipe 52 and the water pipe joint 53, preventing them from rotating relative to each other circumferentially, and ensuring that when the linkage 40 pushes the water pipe joint 53, the self-cleaning water pipe 52 can be driven to rotate synchronously.

[0082] The outer pipe wall of the water inlet port 521 having a rotation prevention protrusion 532b and the hole wall of the water passing hole 532a having a rotation prevention groove have basically the same technical effects as above, so they will not be elaborated here.

[0083] In addition, based on any of the above embodiments, the water spraying part 51 is provided as a water spraying hole, the water spraying hole is a strip-shaped hole, and the length extension direction of the strip-shaped hole is consistent with the axial direction of the self-cleaning water pipe 52; or, the water spraying part 51 includes at least two water spraying holes, and the at least two water spraying holes are arranged at intervals along the axial direction of the self-cleaning water pipe 52.

[0084] No matter whether one water spray hole is used and is set as a strip hole, or at least two water spray holes are used and are set at intervals, it is ensured that the extension length of the total water spray surface is not less than the length of the cleaning roller 21 and the wiper 22. Not only does it ensure that the water spray is evenly distributed, but the water spray can completely cover the cleaning roller 21 and the wiper 22, thereby improving the cleaning effectiveness. After the cleaning module 100 completes the self-cleaning operation, the wiper 22 no longer needs to be manually disassembled and cleaned manually, thereby improving the degree of automation of the cleaning robot. At the same time, the cleaning of the wiper 22 also ensures the stability of the cleaning roller 21 in scraping off the sewage.

[0085] Optionally, the wiper member 22 may be a long strip of plate, rod or the like.

[0086] Please continue reading Figure 3 and Figure 4 In addition, based on any of the above embodiments, the cleaning assembly 20 also includes a cleaning bracket 23 rotatably connected to the frame 10, the cleaning roller 21 is rotatably connected to the cleaning bracket 23, the cleaning pipe group 50 is rotatably connected to the cleaning bracket 23, the wiper 22 is fixedly connected to the cleaning bracket 23, and the cleaning bracket 23 drives the cleaning roller 21, the wiper 22 and the cleaning pipe group 50 to switch between the raised position and the lowered position.

[0087] Furthermore, the cleaning bracket 23 is arranged between the first connecting rod 12 and the second connecting rod 13, one side of the cleaning bracket 23 is rotatably connected to the first connecting rod 12, and the other side of the cleaning bracket 23 is rotatably connected to the second connecting rod 13 through the cleaning tube group 50 and the linkage 40.

[0088] In one embodiment, the cleaning bracket 23 is rotatably connected to the lifting link 30, and the lifting link 30 drives the cleaning bracket 23 to move upward, thereby driving the cleaning roller 21, the wiper 22 and the cleaning pipe group 50 to move to the lifting position, and during the upward movement of the cleaning bracket 23, the linkage 40 can push the cleaning pipe group 50 to rotate relative to the cleaning bracket 23 by a preset angle so that the water spray part 51 switches to face the wiper 22; the lifting link 30 drives the cleaning bracket 23 to move downward, thereby driving the cleaning roller 21, the wiper 22 and the cleaning pipe group 50 to move to the lowered position, and during the upward movement of the cleaning bracket 23, the linkage 40 can push the cleaning pipe group 50 to rotate relative to the cleaning bracket 23 so that the water spray part 51 switches to face the cleaning roller 21. In some embodiments, the cleaning assembly 20 also includes a driving member, the cleaning roller 21 includes a roller body 211 and a cleaning cloth 212, the driving member is mounted on the cleaning bracket 23 and is transmission-connected to the roller body 211, the roller body 211 is rotatably mounted in the cleaning bracket 23, and the cleaning cloth 212 is detachably mounted on the outer peripheral surface of the roller body 211.

[0089] The cleaning bracket 23 is used to be rotatably installed on the frame 10 through a rotating shaft, and an installation cavity is formed inside the cleaning bracket 23. The self-cleaning water pipe 52, the cleaning roller 21, and the water scraping member 22 are all installed in the installation cavity, making the overall structure of the cleaning assembly 20 compact and reasonably arranged. For example, the self-cleaning water pipe 52 is rotatably connected to the cleaning bracket 23 by means such as hinging.

[0090] The driving member can be a driving device such as a motor. The motor drives the rotation of the roller body 211, thereby driving the cleaning cloth 212 to wipe the ground in a rotating manner. Cooperating with the movement of the cleaning robot, the purpose of cleaning and mopping the ground can be achieved.

[0091] Furthermore, the cleaning assembly 20 further includes a water collecting tank 24. The water scraping member 22 and the water collecting tank 24 are respectively installed inside the cleaning bracket 23, and the water scraping member 22 is located between the water collecting tank 24 and the cleaning roller 21. The water scraping member 22 is provided with a water scraping portion 221 and a water guiding portion 222. The water scraping portion 221 abuts against the cleaning cloth 212. One end of the water guiding portion 222 is connected to the water scraping portion 221, and the other end is connected and cooperated with the notch of the water collecting tank 24. The water scraping portion 221 is used to scrape the sewage on the cleaning cloth 212, and the water guiding portion 222 is used to guide the scraped sewage and the sewage generated by the water spraying portion 51 for cleaning the water scraping member 22 into the water collecting tank 24. In this way, it can be ensured that the sewage can be collected into the water collecting tank 24 in a timely and complete manner, avoiding sewage leakage and causing pollution. The sewage in the water collecting tank 24 enters the sewage tank by means of suction.
