Description

Cleaning modules, cleaning robots and cleaning systems

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 2023116129929 and application name “Cleaning Module, Cleaning Robot and Cleaning System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of intelligent cleaning equipment, and in particular to a cleaning module, a cleaning robot and a cleaning system. Background Art

[0003] Cleaning robots are a type of intelligent device that can automatically perform cleaning tasks instead of people. Their advent not only frees people's hands and reduces the labor intensity of cleaning operations, but also achieves better cleaning effects and more efficient cleaning speeds. Therefore, they are deeply favored by consumers.

[0004] Compared to traditional cleaning robots that only have a sweeping function, cleaning robots with combined washing, mopping and sweeping functions are more popular in the market because they can achieve better cleaning results. The component that performs the washing and mopping functions on the cleaning robot is a roller mop module, which is usually equipped on a sweeper. After completing a floor cleaning operation and when the sweeper returns to the workstation, the cleaning mechanism automatically cleans the mop to remove dust, hair and other dirt adhering to the mop. However, in reality, there are other functional components in the sweeper that cooperate with the roller mop, and these functional components are also prone to adhesion of dirt. Therefore, cleaning the mop with the cleaning mechanism alone is not enough 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 labor-intensive, and the user experience is not good.

[0005] Summary of the Invention

[0006] Based on this, it is necessary to provide a cleaning module, a cleaning robot and a cleaning system to address the problem that it is impossible to achieve thorough and effective cleaning with a mop, which makes manual cleaning time-consuming and labor-intensive, and the user experience is poor.

[0007] In one aspect, the present application provides a cleaning module comprising:

[0008] frame;

[0009] A cleaning assembly, the cleaning assembly being rotatably connected to the frame and having a lift position and a lower position that can be switched between each other, and the cleaning assembly comprising a cleaning roller and a wiper member that are mounted in conjunction with each other;

[0010] a linkage member, one end of which is rotatably connected to the frame; and

[0011] a cleaning pipe assembly, the cleaning pipe assembly being rotatably connected to the cleaning assembly and the other end of the linkage, the cleaning pipe assembly being provided with a water spraying portion;

[0012] When the cleaning assembly is in the lowered position, the water spray portion is arranged toward the cleaning roller; when the cleaning assembly is switched to the raised position, the linkage member synchronously drives the cleaning tube group to rotate relative to the cleaning assembly so that the water spray portion is switched to face the wiper.

[0013] The cleaning module of the above scheme is applied to the cleaning robot. When the cleaning robot moves in the place to be cleaned, the water spraying part of the cleaning pipe group is arranged towards the cleaning roller of the cleaning component in the lowered position, and the water spraying part sprays water to the cleaning roller to wet the cleaning roller, so as to meet the cleaning roller's ability to complete the sweeping and mopping process on the floor of the place to be cleaned; when the cleaning operation is finished, the cleaning robot returns to the workstation, and the cleaning pipe group can continue to spray water to the cleaning roller to complete the self-cleaning process of the cleaning roller. After that, the cleaning component moves upward under the drive of the lifting mechanism, thereby pulling the cleaning component to rotate upward relative to the frame and enter the lifting position The cleaning roller is then cleaned by the water jet, which in turn cleans the dirt adhering to the wiper component and prevents the wiper component from causing secondary contamination to the cleaned roller. This allows for deep cleaning of the cleaning module and ensures that the cleaning component is thoroughly cleaned. This eliminates the need for regular disassembly of the cleaning module and manual deep cleaning of the above components, which saves time and effort due to frequent assembly and disassembly operations.

[0014] On the other hand, the present application also provides a cleaning robot, which includes the cleaning module as described above; and

[0015] A lifting mechanism is connected in transmission with the cleaning assembly, and is used to drive the cleaning assembly to switch between the lifting position and the lowering position.

[0016] In addition, the present application also provides a cleaning system, which includes:

[0017] Workstations; and,

[0018] The cleaning robot as described above is used to return to the workstation to complete the cleaning operation.

DETAILED DESCRIPTION

[0030] To facilitate understanding of the present application, a more comprehensive description of the present application will be provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. It should be understood that these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number or order of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0033] In existing technologies, when a sweeper is cleaning, a cleaning mechanism automatically cleans the mop to remove dirt, dust, hair, and other impurities adhering to the mop. However, sweepers contain other functional components that work with the roller mop, and these components are also prone to collecting dirt and staining the mop. Therefore, cleaning the mop with the cleaning mechanism alone is not sufficient to ensure thorough cleaning. The roller mop module must be regularly disassembled for manual deep cleaning, which is time-consuming and labor-intensive, resulting in a poor user experience.

[0034] To address this issue, this application proposes a cleaning system that can be used for automated cleaning operations in homes, offices, stadiums, and other venues, replacing traditional manual cleaning methods with improved quality, increased efficiency, and reduced costs. Specifically, the cleaning system includes a workstation and a cleaning robot.

[0035] The workstation is used to house and service cleaning robots, meeting their various needs. For example, the workstation is equipped with a storage compartment. When the cleaning robot is not in operation (such as standby or shutdown), the cleaning robot returns to the compartment. At this time, the cleaning robot and the workstation are integrated into one, which facilitates centralized management and reduces site space usage.

[0036] Furthermore, the cleaning robot is designed to return to the workstation to complete its cleaning operations. For example, the workstation is equipped with a cleaning mechanism that cleans dirty components of the cleaning robot upon its return to the storage compartment. Furthermore, the workstation is equipped with charging, sterilization, and drying mechanisms to meet the cleaning robot's power and endurance requirements, as well as its sterilization and disinfection needs, significantly enhancing its performance.

[0037] In the present application, the cleaning robot can specifically be a sweeper, which includes a cleaning module 100. In addition to the basic function of cleaning dust and other impurities on the ground, the cleaning module 100 also has functions such as washing and mopping the ground, and even drying the ground, thereby meeting the different cleaning needs of people or different venues.

[0038] 1 and 2 , a cleaning module 100 according to an embodiment of the present application is shown, which includes a frame 10 , a cleaning assembly 20 , a linkage 40 , and a cleaning pipe assembly 50 .

[0039] The frame 10 is used to be connected and fixed to the main structure (such as the housing) of the cleaning robot, and plays the role of loading and fixing components such as the cleaning component 20, the linkage member 40, and the cleaning pipe group 50.

[0040] 3 and 4 , the cleaning assembly 20 is rotatably connected to the frame 10 and has a lift position (as shown in FIG. 4 ) and a lower position (as shown in FIG. 3 ) that can be switched between each other. The cleaning assembly 20 includes a cleaning roller 21 and a wiper 22 that are mounted in conjunction with each other.

[0041] The cleaning roller 21 and the wiper 22 may be arranged relative to and in contact with each other, and the wiper 22 may scrape and collect the sewage on the cleaning roller 21 , thereby maintaining the cleaning effect of the cleaning roller 21 .

[0042] It is understood that when the cleaning assembly 20 is in the lowered position, the cleaning roller 21 can normally contact the surface to be cleaned, thereby performing a cleaning operation on the surface to be cleaned, as shown in Figure 3. For example, when the cleaning roller 21 rotates in a dry state, it cooperates with the negative pressure suction mechanism on the cleaning robot to 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.

[0043] It is understandable that when the cleaning assembly 20 is in the raised position, the cleaning roller 21 is spaced apart from the surface to be cleaned and cannot contact the surface to be cleaned.

[0044] Furthermore, in order to enable the cleaning component 20 to switch between the raised position and the lowered position, the cleaning robot also includes a lifting mechanism, which lifts and lowers the cleaning component 20, thereby enabling the cleaning component 20 to switch between the raised position and the lowered position, thereby making the cleaning roller 21 spaced apart from the surface to be cleaned or in normal contact with the surface to be cleaned.

[0045] The lifting mechanism may be any one of an electric push rod, a telescopic rod mechanism, etc., and may be selected according to actual needs.

[0046] In one embodiment, the lifting mechanism includes a lifting link 30 connected to the cleaning assembly 20, and the lifting link 30 provides the cleaning assembly 20 with a lifting force for upward movement and a release force for downward movement, thereby lifting the cleaning roller 21 to a position spaced apart from the surface to be cleaned or lowering the cleaning roller 21 to normally contact the surface to be cleaned.

[0047] 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 a raised position and a lowered position.

[0048] One end of the linkage member 40 is rotatably connected to the frame 10 via a shaft connection or other means, the cleaning pipe assembly 50 is rotatably connected to the cleaning assembly 20 via a hinge or other means, and the cleaning pipe assembly 50 is rotatably connected to the other end of the linkage member 40 via a hinge or other means. In addition, the cleaning pipe assembly 50 is provided with a water spray portion 51.

[0049] When the cleaning assembly 20 is in the lowered position, the water spraying portion 51 is disposed toward the cleaning roller 21 .

[0050] When performing cleaning operations, the water spraying part 51 is set toward the cleaning roller 21, and water or other cleaning liquid is sprayed toward 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 floor, but also further wash and mop the floor to thoroughly remove stubborn stains or residual dust adhering to the floor.

[0051] When the cleaning assembly 20 is switched to the raised position, the linkage member 40 simultaneously drives the cleaning tube assembly 50 to rotate relative to the cleaning assembly 20 by a preset angle, so that the water spray portion 51 is switched to face the wiper member 22 .

[0052] It is necessary to explain that the water spray portion 51 is directed toward the wiper element 22. The water spray portion 51 may be completely directed toward the wiper element 22 or partially directed toward the wiper element 22. When the water spray portion 51 is partially directed toward the wiper element 22, part of the sprayed water can clean the wiper element 22 and the other part can clean the cleaning roller 21, so that the cleaning effect is more comprehensive.

[0053] In summary, the implementation of the technical solution of this embodiment will have at least the following beneficial effects: the cleaning module 100 of the above solution is applied to the cleaning robot, and when the cleaning robot moves in the area to be cleaned, the water spraying part 51 of the cleaning pipe group 50 is arranged toward the cleaning roller 21 of the cleaning component 20 in the lowered position, and the water spraying part 51 sprays water to the cleaning roller 21 to wet the cleaning roller 21, so as to satisfy the cleaning roller 21 to complete the sweeping and mopping of the area to be cleaned; when the cleaning operation is completed, the cleaning robot returns to the workstation, and the cleaning pipe group 50 can also continue to spray water to the cleaning roller 21 to complete the self-cleaning process of the cleaning roller 21. After that, the cleaning component 20 is driven by the lifting mechanism to rotate upward relative to the frame 10. Switch to the lifting position. During this process, the linkage part 40 will also rotate synchronously relative to the frame 10, so that the linkage part 40 can push the cleaning pipe group 50 to rotate relative to the cleaning component 20 by a preset angle (such as 15°, 17°, etc.), so that the water spray part 51 switches to face the wiper part 22. The water sprayed from the water spray part 51 cleans the dirt adhered to the wiper part 22, thereby preventing the wiper part 22 from causing secondary pollution to the cleaning roller 21 after cleaning. In this way, the deep cleaning of the cleaning module 100 can be completed, ensuring that the cleaning component 20 is thoroughly cleaned. In this way, people no longer need to disassemble the cleaning module 100 regularly and rely on manual deep cleaning of the above-mentioned components, avoiding people from wasting manpower and time due to frequent assembly and disassembly operations, which helps to improve people's user experience.

[0054] Among them, the linkage part 40 can be in the form of a connecting arm such as a rocker arm, a swing arm, or in the form of a connecting rod mechanism. It only needs to ensure that when the cleaning component 20 is switched to the lifted position, the linkage part 40 can synchronously push the cleaning pipe group 50 to rotate relative to the cleaning component 20, so that the water spray part 51 switches to face the wiper component 22 to clean the dirt adhered to the wiper component 22.

[0055] Please continue to refer to Figures 1, 3 and 4. Based on the above embodiment, 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 spaced apart along the length direction of the main rod 11, wherein 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 connected and fixed 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 via a first rotating shaft 14. One end of the second connecting rod 13 is connected and fixed to the other end of the main rod 11 in the length direction, and the other end of the second connecting rod 13 is rotatably connected to one end of the linkage member 40 via a second rotating shaft 15.

[0056] In the height direction, the length of the second connecting rod 13 is smaller than the length of the first connecting rod 12 .

[0057] It should be noted that the above-mentioned height direction specifically refers to the height direction of the cleaning module 100, that is, the Z-axis direction in Figures 1 and 3; in addition, the length direction of the cleaning module 100 is the Y-axis direction, and the width direction is the X-axis direction.

[0058] 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.

[0059] Since the first connecting rod 12 and the second connecting rod 13 are respectively located at the two ends of the length direction of the main rod 11, the rotational connection between the first connecting rod 12 and the cleaning component 20 and the rotational connection between the second connecting rod 13 and the linkage member 40 are separated by a sufficiently large installation distance, thereby avoiding interference problems when the cleaning component 20 and the linkage member 40 rotate.

[0060] And because the length of the second connecting rod 13 is shorter than that of the first connecting rod 12, both are arranged vertically in the installed and used state, and the end of the second connecting rod 13 away from the main rod 11 is closer to the cleaning tube group 50, so that the length of the linkage member 40 can be set shorter to meet the needs of connecting the second connecting rod 13 and the cleaning tube group 50. And precisely because the length of the linkage member 40 is shorter, when the lifting mechanism pulls the cleaning component 20 upward to rotate a smaller angle, the linkage member 40 can synchronously drive the cleaning tube group 50 to rotate a smaller preset angle than the cleaning component 20, thereby switching the water spray part 51 to face the wiper 22, making the switching response speed of the entire mechanism faster, which helps to improve the self-cleaning efficiency of the cleaning module 100.

[0061] Referring to Figure 3, in one embodiment, when the cleaning assembly 20 is in the lowered position, the cleaning roller 21 passes through the water spray portion 51 along its vertical center axis, or the water spray portion 51 is located on the side of the center axis closer to the wiper element 22. Considering that the cleaning assembly 20 is lifted a short distance, this arrangement ensures that when the cleaning assembly 20 is lifted a short distance and in the raised position, the water spray portion 51 can rotate a small angle to accurately face the wiper element 22 without being blocked or interfered with by the cleaning roller 21.

[0062] Please continue to refer to Figures 1 and 5 to 8. In some embodiments, the cleaning pipe group 50 includes a self-cleaning water pipe 52 and a water pipe connector 53. The self-cleaning water pipe 52 is rotatably installed in the cleaning component 20. The self-cleaning water pipe 52 is provided with a water spray portion 51, and the self-cleaning water pipe 52 is also provided with a water inlet 521. The water pipe connector 53 is connected to the water inlet 521 and is located outside the cleaning component 20. The water pipe connector 53 includes a connecting arm 531, which is rotatably connected to the other end of the linkage 40.

[0063] The water pipe connector 53 is mounted on the outside of the cleaning assembly 20, making it easier to connect to the water supply pipe. This allows cleaning water (i.e., tap water or other types of cleaning water) to enter the water inlet 521 through the water pipe connector 53 and then flow into the self-cleaning water pipe 52. It is ultimately sprayed out from the water spray section 51 to clean the cleaning roller 21 or the wiper element 22. The linkage member 40 is rotatably connected to the connecting arm 531, making it easier to simultaneously push the water pipe connector 53 and the self-cleaning water pipe 52 to rotate, thereby adjusting the water spray direction of the water spray section 51.

[0064] Furthermore, the water pipe connector 53 includes a pipe body 532 and a water pipe interface 533. The connecting arm 531 and the water pipe interface 533 are respectively mounted on the pipe body 532, and the connecting arm 531 and the water pipe interface 533 are arranged at an angle to avoid interference with the linkage 40. In addition, the pipe body 532 is provided with a water hole 532a, and the water pipe interface 533 is connected to the water inlet 521 through the water hole 532a.

[0065] The water pipe interface 533 is cylindrical, with two through-holes and a hollow interior. It is integrally or detachably connected to the pipe body 532. The water pipe interface 533 is designed to be directly plugged into and secured to the water supply pipe, simplifying installation. Furthermore, to prevent the water supply pipe from easily falling off the water pipe interface 533, the outer wall of the water pipe interface 533 is provided with an anti-slip pattern to increase friction with the water supply pipe. For example, in this embodiment, the anti-slip pattern comprises multiple circles of anti-slip protrusions spaced along the axial direction of the water pipe interface 533.

[0066] During installation, the water inlet pipe 521 is inserted into the water hole 532a to achieve communication between the water pipe interface 533, the water hole 532a and the water inlet pipe 521, which helps to shorten the length of the cleaning water flow path and make the water supply to the self-cleaning water pipe 52 more efficient.

[0067] Please continue to refer to Figure 6. In addition, in order to prevent leakage at the connection between the water inlet pipe 521 and the water hole 532a, a sealing ring 54 is installed outside the water inlet pipe 521 or inside the water hole 532a. The sealing ring 54 can improve the sealing performance.

[0068] Please continue to refer to Figures 6 and 8. Based on the above embodiment, the pipe end wall of the water inlet pipe 521 is recessed with a rotation-stop notch 521a, and the hole wall of the water hole 532a is provided with a rotation-stop protrusion 532b. The rotation-stop notch 521a and the rotation-stop protrusion 532b are engaged with each other to assemble and fix the self-cleaning water pipe 52 and the water pipe joint 53.

[0069] Alternatively, as an alternative to the above embodiment, the outer tube wall of the water inlet pipe 521 is provided with a stop protrusion 532b, and the hole wall of the water hole 532a is recessed with a stop groove, and the stop protrusion 532b is clamped in the stop groove to assemble and fix the self-cleaning water pipe 52 and the water pipe joint 53.

[0070] Taking the example of the water inlet pipe 521 having a stop notch 521a on the pipe end wall and the water hole 532a having a stop protrusion 532b on the hole wall, when the water inlet pipe 521 is inserted into the water hole 532a, the stop protrusion 532b automatically fits into the stop notch 521a, thereby forming an installation limit for the self-cleaning water pipe 52 and the water pipe connector 53, so that the two cannot rotate relative to each other, thereby ensuring that the linkage part 40 can synchronously drive the self-cleaning water pipe 52 to rotate when pushing the water pipe connector 53.

[0071] The outer tube wall of the water inlet pipe 521 is provided with a rotation-stopping protrusion 532b and the hole wall of the water hole 532a is provided with a rotation-stopping groove, which have basically the same technical effects as above, so they are not described here in detail.

[0072] In addition, based on any of the above embodiments, the water spray portion 51 is set as a water spray hole, which is a strip hole, and the length extension direction of the strip hole is consistent with the axial direction of the self-cleaning water pipe 52; or, the water spray portion 51 includes at least two water spray holes, and at least two water spray holes are arranged at intervals along the axial direction of the self-cleaning water pipe 52.

[0073] 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. It not only ensures that the water spray is evenly distributed, but also that 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 away sewage.

[0074] Optionally, the wiper member 22 may be a long strip of plate, rod, etc.

[0075] Please continue to refer to Figures 3 and 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.

[0076] 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.

[0077] 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 lifted 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 is switched 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 is switched to face the cleaning roller 21. In some embodiments, the cleaning assembly 20 also includes a driving member, and the cleaning roller 21 includes a roller body 211 and a cleaning cloth 212. The driving member is installed on the cleaning bracket 23 and is transmission-connected to the roller body 211. The roller body 211 is rotatably installed in the cleaning bracket 23, and the cleaning cloth 212 is detachably installed on the outer peripheral surface of the roller body 211.

[0078] The cleaning bracket 23 is rotatably mounted to the frame 10 via a rotating shaft. A mounting cavity is formed within the cleaning bracket 23. The self-cleaning water pipe 52, the cleaning roller 21, and the wiper element 22 are all mounted within the mounting cavity, making the overall structure of the cleaning assembly 20 compact and well-organized. For example, the self-cleaning water pipe 52 is rotatably connected to the cleaning bracket 23 by a hinge or other means.

[0079] The driving member can be a driving device such as a motor. The motor drives the drum body 211 to rotate, thereby driving the cleaning cloth 212 to wipe the floor in a rotating manner. Cooperating with the movement of the cleaning robot, the purpose of sweeping and mopping the floor can be achieved.

[0080] Furthermore, the cleaning assembly 20 also includes a water collection tank 24. The wiper member 22 and the water collection tank 24 are respectively installed in the cleaning bracket 23, and the wiper member 22 is located between the water collection tank 24 and the cleaning roller 21.
