Description

Technical Field

[0001] This application belongs to the field of floor cleaning equipment technology, and particularly relates to a mopping device and a mopping robot. Background Technology

[0002] To better meet the needs of household floor cleaning, mopping robots are gradually entering people's daily lives. Mopping robots are usually equipped with two mopping mechanisms, which are driven to rotate to clean floors or tiles. However, when mopping robots walk on carpets, the mopping mechanisms will wet the carpet, causing secondary cleaning. Therefore, it is necessary to avoid walking on carpets as much as possible.

[0003] Currently, to address the issue of mopping robots being unable to walk on carpets, a structure has been proposed that uses a telescopic mechanism to lift the mop mechanism, thereby preventing the mop from contacting the carpet. However, mopping robots with this structure typically have one lifting mechanism for each mop mechanism, or two lifting mechanisms for two mop mechanisms. This makes the structure of the mopping robot complex, its overall size large, and the synchronization of the lifting of the two mop mechanisms poor. Summary of the Invention

[0004] The purpose of this application is to provide a mopping device and a mopping robot, which aims to solve the technical problems of existing mopping robots having complex structures, large overall size, and poor synchronization of mop lifting mechanism.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a mopping device, comprising,

[0006] support;

[0007] At least two mop mechanisms, each mop mechanism including a rotating shaft and a mop assembly, the mop assembly being connected to one end of the rotating shaft;

[0008] A rotary drive mechanism, connected to the bracket, wherein the drive end of the rotary drive mechanism is slidably connected to the rotating shaft and capable of driving the rotating shaft to rotate; and

[0009] A lifting drive mechanism is provided, which is connected to the bracket. The driving end of the lifting drive mechanism is provided with a connecting plate, and the other end of each of the rotating shafts is connected to the connecting plate. The lifting drive mechanism is used to drive the rotating shafts to slide up and down relative to the driving end of the rotation drive mechanism.

[0010] Optionally, the lifting drive mechanism includes a first drive member and a lead screw. The first drive member is mounted on the bracket, and the drive end of the first drive member is connected to the lead screw and is used to drive the lead screw to rotate. The connecting plate is screwed to the lead screw.

[0011] Optionally, the connecting plate includes a plate body and a slider disposed on the plate body, the slider being screwed to the lead screw, and the rotating shaft being connected to the plate body.

[0012] Optionally, the bracket is provided with a guide rod, which is parallel to the lead screw. The connecting plate is provided with a guide hole, and the guide rod passes through the guide hole and can slide within the guide hole.

[0013] Optionally, the rotary drive mechanism includes a second drive member and at least two gearboxes, the input end of each gearbox being connected to the drive end of the second drive member, and the output end of each gearbox being slidably connected to each of the rotating shafts in a one-to-one correspondence.

[0014] Optionally, the gearbox includes a housing, an input shaft mounted on the housing, and an output wheel mounted in the housing and connected to the input shaft; the driving end of the second driving member is connected to the input shaft and is used to drive the input shaft to rotate the output wheel; the other end of the rotating shaft passes through the housing and is connected to the connecting plate.

[0015] A through hole is provided at the middle position of the output wheel, the rotating shaft passes through the through hole and can rotate with the output wheel and slide within the through hole.

[0016] Optionally, the connecting plate has several connecting holes, and the other end of the rotating shaft passes through the housing and the connecting holes and is limited by a snap ring.

[0017] Optionally, the gearbox is provided with an elastic element, the rotating shaft is a stepped shaft, the larger section of the stepped shaft passes through the through hole and exits from the gearbox to connect with the mop assembly; the smaller section of the stepped shaft exits from the gearbox and exits from the connecting hole.

[0018] The elastic element is sleeved on the small section of the stepped shaft, and the two ends of the elastic element abut against the inner wall of the gearbox and the stepped surface of the stepped shaft, respectively.

[0019] Optionally, the bracket is provided with a micro switch for detecting the position of the connecting plate.

[0020] The mopping device provided in this application has at least one of the following technical effects: When in use, the drive end of the rotary drive mechanism drives the rotating shaft to rotate, which in turn drives the mop assembly to rotate. The rotating mop assembly contacts the ground and rotates relative to the ground, thus achieving floor cleaning. Before moving onto the carpet, the drive end of the lifting drive mechanism drives the connecting plate to rise. The rising connecting plate drives all the rotating shafts to rise, and the rising shafts simultaneously move the mop assembly upwards, preventing the mop assembly from contacting the carpet and wetting it after the mopping device moves onto the carpet, thus allowing the mopping robot to move freely on the carpet. Furthermore, through the connecting plate, the mopping device only requires one lifting drive mechanism to move all the mop assemblies upwards, resulting in fewer parts and a simpler structure, which greatly saves on the cost of the lifting drive mechanism. This design reduces the overall size of the mopping device by saving space. Because the device uses a single lifting drive mechanism to move all mop components upwards, the synchronicity of the upward movement of the mop components is excellent. Furthermore, the drive end of the rotary drive mechanism is slidably connected to the rotating shaft, preventing interference between the rotating shaft and the rotary drive mechanism in the lifting direction. Simultaneously, the lifting drive mechanism only needs to move the mop components up and down, without needing to move the rotary drive mechanism, making the lifting of the mop mechanism easier. This also allows for the selection of a smaller, less powerful lifting drive mechanism, further saving space and improving the overall compactness of the mopping robot. Moreover, when the lifting mechanism lifts the mop components, they separate from the carpet, thus solving the problem of significant component damage caused by sliding friction between the mop components and the carpet when the mopping robot walks on carpets.

[0021] Another technical solution adopted in this application is: a floor mopping machine, including the above-mentioned floor mopping device.

[0022] The mopping robot of this embodiment, by employing the aforementioned mopping device, drives the mop assembly upwards via the drive end of the lifting drive mechanism. This prevents the mop assembly from contacting and wetting the carpet after the mopping device moves onto the carpet, allowing the mopping robot to move freely on the carpet. Furthermore, through the connecting plate, the mopping device requires only one lifting drive mechanism to move all mop assemblies upwards. This results in fewer parts, a simpler structure, and significantly reduced installation space for the lifting drive mechanism, thus reducing the overall size of the mopping device. Because the mopping device uses a single lifting drive mechanism to drive all mop assemblies upwards, the synchronicity of the upward movement of the mop assemblies is excellent. Additionally, the rotation... The drive end of the rotary drive mechanism is slidably connected to the rotating shaft. During the process of the lifting drive mechanism driving the rotating shaft to rise and fall, interference between the rotating shaft and the rotary drive mechanism in the lifting direction is avoided. At the same time, the lifting drive mechanism only needs to drive the mop mechanism to rise and fall, without driving the rotary drive mechanism. This makes the lifting of the mop mechanism easier and allows for the selection of a smaller and less powerful lifting drive mechanism, further saving space and improving the overall compactness of the mopping robot. In addition, when the lifting mechanism lifts the mop assembly, the mop assembly separates from the carpet. This also solves the problem of significant component damage caused by the sliding friction between the mop assembly and the carpet when the mopping robot walks on the carpet.

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0037] 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 specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] like Figures 1-2As shown, in one embodiment of this application, a mopping device is provided, which is suitable for use in a mopping robot and can cooperate with the walking mechanism of the mopping robot. The movement of the walking mechanism drives the mopping device to move, thereby achieving large-area mopping and sweeping cleaning of the floor. The floor can be a wood floor or a tile.

[0040] Combination Figure 1 As shown, the mopping device includes a bracket 10, a rotary drive mechanism 30, a lifting drive mechanism 40, and at least two mop mechanisms 20. Each mop mechanism 20 includes a rotating shaft 21 and a mop assembly 22, with the mop assembly 22 connected to one end of the rotating shaft 21. The rotary drive mechanism 30 is connected to the bracket 10, and its drive end is slidably connected to the rotating shaft 21, enabling it to drive the rotating shaft 21 to rotate. The lifting drive mechanism 40 is connected to the bracket 10, and its drive end is provided with a connecting plate 50. The other end of each rotating shaft 21 is connected to the connecting plate 50. The lifting drive mechanism 40 is used to drive the rotating shaft 21 to slide up and down relative to the drive end of the rotary drive mechanism 30.

[0041] The following further describes the mopping device according to the embodiments of this application. When in use, the drive end of the rotary drive mechanism 30 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the mop assembly 22 to rotate. The rotating mop assembly 22 contacts the ground and rotates relative to the ground, thus achieving the wiping and cleaning of the ground. Before the mopping device moves to the carpet, the drive end of the lifting drive mechanism 40 drives the connecting plate 50 to rise. The rising of the connecting plate 50 drives all the rotating shafts 21 to rise, and the rising of the rotating shafts 21 simultaneously drives the mop assembly 22 to move upward, preventing the mop assembly 22 from contacting the carpet and wetting the carpet after the mopping device moves to the carpet, thus enabling the mopping robot to move freely on the carpet. Furthermore, through the connecting action of the connecting plate 50, the mopping device only needs one lifting drive mechanism 40 to achieve the upward movement of all the mop assemblies 22. It has fewer parts and a simpler structure, which can greatly save the installation space of the lifting drive mechanism 40 and reduce the overall size of the mopping device.

[0042] In this embodiment, since the mopping device uses a lifting drive mechanism 40 to drive all the mop assemblies 22 to move upward, the synchronicity of the upward movement of the mop assemblies 22 is good. In addition, the drive end of the rotary drive mechanism 30 is slidably connected to the rotating shaft 21. During the process of the lifting drive mechanism 40 driving the rotating shaft 21 to move up and down, interference between the rotating shaft 21 and the rotary drive mechanism 30 in the lifting direction is avoided. At the same time, the lifting drive mechanism 40 only needs to drive the mop assembly 20 to move up and down, without having to drive the rotary drive mechanism 30 to move up and down. This makes the lifting of the mop assembly 20 easier. A smaller and less powerful lifting drive mechanism 40 can also be selected, further saving space and improving the structural compactness of the entire mopping robot.

[0043] In this embodiment, after the lifting mechanism lifts the mop assembly 22, the mop assembly 22 separates from the carpet. This also solves the problem of significant component damage caused by sliding friction between the mop assembly 22 and the carpet when the mopping robot walks on the carpet. When the mopping device leaves the carpet and the floor needs to be cleaned, the drive end of the lifting drive mechanism 40 drives the connecting plate 50 to move downwards. The connecting plate 50 drives the rotating shaft 21 and the mop assembly 22 to move downwards until the mop assembly 22 contacts the ground. At the same time, the rotation drive mechanism 30 drives the mop assembly 22 to rotate, thereby continuing to rotate and wipe the ground. When the lifting mechanism lifts the mop assembly 22 and separates it from the ground, the rotation drive mechanism 30 may or may not drive the mop assembly 22 to rotate; the specific choice can be made according to actual needs and is not limited here.

[0044] It should be noted that the mop assembly 22 includes a mounting plate 221 and a mop that is detachably connected to the mounting plate 221. The end of the rotating shaft 21 is connected to the mounting plate 221. The drive end of the rotary drive mechanism 30 drives the rotating shaft 21 to rotate. The rotating shaft 21 drives the mounting plate 221 and the mop on the mounting plate 221 to rotate. The mop is pressed against the ground and rotated to wipe, thus achieving the cleaning of the ground.

[0045] In this embodiment, the number of mop mechanisms 20 can be two, three, four or more, and the specific number can be set according to actual needs, and is not limited here.

[0046] In this embodiment, the bottom of the mopping robot is also equipped with a cleaning component for cleaning the floor. When the mopping robot walks on the carpet, the cleaning component can also clean the carpet, thus achieving carpet cleaning. The cleaning component can be a brush, a vacuum cleaner, a scraper, or other cleaning parts.

[0047] In another embodiment of this application, combined with Figure 1 and Figure 2As shown, the lifting drive mechanism 40 of the provided mopping device includes a first drive member 41 and a lead screw 42. The first drive member 41 is mounted on the bracket 10, and its drive end is connected to the lead screw 42 and used to drive the lead screw 42 to rotate. The connecting plate 50 is screwed to the lead screw 42. Specifically, the first drive member 41 drives the lead screw 42 to rotate. During the rotation of the lead screw 42, the connecting plate 50 slides up and down along the lead screw 42, thereby realizing the up and down movement of the connecting plate 50. With the structure of the lead screw 42 and the first drive member 41, the up and down movement of the connecting plate 50 is stable and reliable, the mop is lifted accurately, and the risk of wetting the carpet is small. In specific applications, threaded holes can be directly machined on the connecting plate 50, and the lead screw 42 is screwed into the threaded holes, so that the rotation of the lead screw 42 directly drives the connecting plate 50 to move up and down. The specific structure can be designed according to actual needs and is not limited here.

[0048] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the connecting plate 50 of the provided mopping device includes a plate body 51 and a slider 52 disposed on the plate body 51. The rotating shaft 21 is connected to the plate body 51, and the slider 52 is screwed to the lead screw 42. The rotating lead screw 42 drives the slider to move up and down, and the slider 52 drives the plate body 51 to move up and down. In this way, there is no need to open a threaded hole on the plate body 51. The slider 52 can be directly installed on the plate body 51, which reduces the manufacturing difficulty of the connecting plate 50 and reduces the production cost. In practical applications, the plate body 51 is provided with a fixing hole (not shown in the figure), and the slider 52 is fixed in the fixing hole, thereby realizing the fixed connection between the slider 52 and the plate body 51.

[0049] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the bracket 10 of the provided mopping device is equipped with a guide rod 60, which is parallel to the lead screw 42. The connecting plate 50 is provided with a guide hole 511, and the guide rod 60 passes through the guide hole 511 and can slide within the guide hole 511. The guide rod 60 slides within the guide hole 511, thus guiding the up-and-down movement of the connecting plate 50 and ensuring the stable and reliable lifting of the mop assembly 22. Furthermore, under the guidance of the guide rod 60, the up-and-down movement of the connecting plate 50 is smooth and does not skewing, thereby ensuring good synchronization of the lifting of the mop mechanism 20. In practical applications, the guide hole 511 is formed on the plate 51, and the guide rod 60 is clearance-fitted with the guide hole 511. This allows the guide rod 60 to slide within the guide hole 511 as it moves back and forth along the guide rod 60.

[0050] In practical applications, the number of guide rods 60 can be two, three or more, and the specific number can be set according to actual needs, without limitation here.

[0051] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the rotary drive mechanism 30 of the provided mopping device includes a second drive member 31 and at least two gearboxes 32. The input end of each gearbox 32 is connected to the drive end of the second drive member 31, and the output end of each gearbox 32 is slidably connected to each rotating shaft 21. Specifically, the drive end of the second drive member 31 outputs rotational power to the gearbox 32, which then transmits the rotational power to the rotating shaft 21, causing the rotating shaft 21 to rotate. The rotating shaft 21 then drives the mop to rotate, and the mop rotates and wipes the floor, thus achieving floor cleaning. The gearbox 32 structure provides stable and reliable power transmission, good structural compactness, and facilitates the installation of various components of the mopping device, saving installation space.

[0052] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the gearbox 32 of the provided mopping device includes a housing 321, an input shaft disposed on the housing 321, and an output wheel 322 disposed inside the housing 321 and connected to the input shaft; the driving end of the second driving member 31 is connected to the input shaft and is used to drive the input shaft to rotate the output wheel 322; the other end of the rotating shaft 21 passes through the housing 321 and is connected to the connecting plate 50; a through hole 3221 is provided in the middle position of the output wheel 322, the rotating shaft 21 passes through the through hole 3221 and can rotate with the output wheel 322, and can slide in the through hole 3221. Specifically, the rotational power output by the second driving component 31 is transmitted to the output wheel 322 of the gearbox 32 through the input shaft, causing the output wheel 322 to rotate. During the rotation of the output wheel 322, the rotating shaft 21 is driven to rotate, thereby realizing the rotation and wiping of the mop. In addition, the rotating shaft 21 passes through the housing 321 and the output wheel 322 and is connected to the connecting plate 50. On the one hand, this ensures that the rotating shaft 21 can move up and down relative to the housing 321 and the output wheel 322 under the drive of the connecting plate 50, thereby realizing the lifting and lowering of the mop. On the other hand, the connecting plate 50 and the gearbox 32 are distributed along the axial direction of the rotating shaft 21, which can prevent interference between the lifting and lowering of the connecting plate 50 and the rotation of the internal components of the gearbox 32, and improve the stability of the movement of the rotating shaft 21.

[0053] It should be noted that the rotating shaft 21 passes through the through hole 3221 with a clearance fit. This allows the rotating shaft 21 to move axially within the through hole 3221, enabling it to slide within the hole and move up and down relative to the output wheel 322, thus raising and lowering the mop. Furthermore, the rotating shaft 21 is circumferentially fixed within the through hole 3221, ensuring that the output wheel 322 can drive the rotating shaft 21 to rotate. In a specific embodiment, the cross-section of the rotating shaft 21 matches the cross-sectional shape of the through hole 3221. The cross-section of the rotating shaft 21 can be square, triangular, elliptical, semi-circular, or other irregular shapes, as long as it allows the rotating shaft 21 to rotate with the output wheel 322. Alternatively, in another embodiment, a locating pin is provided between the rotating shaft 21 and the through hole 3221 to achieve circumferential fixation between the rotating shaft 21 and the output wheel 322.

[0054] In this embodiment, the input shaft and the output wheel 322 can be directly connected via a gear transmission structure or a worm gear transmission structure. The specific transmission method can be selected according to the implementation requirements and is not limited here, as long as the output wheel 322 can be rotated. In addition, mounting holes 3211 are opened on opposite side walls of the housing 321. The rotating shaft 21 passes through the mounting holes 3211 and is clearance-fitted with the mounting holes 3211. In this way, the rotating shaft 21 can move up and down within the mounting holes 3211. Thus, the rotating shaft 21 can move axially within the mounting holes 3211, which realizes the sliding of the rotating shaft 21 within the through holes 3221, allowing the rotating shaft 21 to move up and down relative to the housing 321.

[0055] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the connecting plate 50 of the provided mopping device has several connecting holes 512. The other end of the rotating shaft 21 passes through the housing 321 and the connecting holes 512 and is limited by a retaining spring 90. Based on this structure, when the lifting drive mechanism 40 drives the connecting plate 50 to move upward, the rotating shaft 21 is limited by the retaining spring 90, preventing the rotating shaft 21 from disengaging from the connecting holes 512 and moving upward with the connecting plate 50, thereby realizing the rise of the rotating shaft 21, i.e., the rise of the mop. The connection method using connecting holes 512 and retaining spring 90 is simple in structure and low in cost. In specific applications, the connecting holes 512 are opened on the plate 51.

[0056] In another embodiment of this application, combined with Figure 1 and Figure 2As shown, the gearbox 32 of the provided mopping device is provided with an elastic element 70. The rotating shaft 21 is a stepped shaft. The large-sized section of the stepped shaft passes through the through hole 3221 and extends out of the housing 321 to connect with the mop assembly 22. The small-sized section of the stepped shaft extends out of the housing 321 and through the connecting hole 512. The elastic element 70 is sleeved on the small-sized section of the stepped shaft. The two ends of the elastic element 70 abut against the inner wall of the gearbox 32 and the stepped surface of the stepped shaft, respectively. When the lifting drive mechanism 40 drives the connecting plate 50 to move downward, the elastic element 70 applies a downward force to the stepped surface of the step shaft, causing the step shaft to move downward, thereby realizing the downward movement of the mop assembly 22. When the mop assembly 22 rotates to wipe the floor, the elastic element 70 can apply a downward elastic force to the stepped surface of the step shaft, causing the mop to exert a downward force on the floor, ensuring that the mop can be pressed firmly on the floor for rotational wiping, thereby improving the cleaning effect. When the lifting drive mechanism 40 drives the connecting plate 50 to rise, the step shaft overcomes the elastic force of the elastic element 70 and lifts the mop assembly 22, thereby enabling the mopping robot to move freely on the carpet.

[0057] In another embodiment of this application, combined with Figure 1 and Figure 2 As shown, the bracket 10 of the provided mopping device is equipped with a micro switch 80 for detecting the position of the connecting plate 50. The micro switch 80 can accurately determine the position of the connecting plate 50, thereby facilitating the lifting and lowering control of the mop assembly 20 of the mopping robot. In a specific embodiment, the bracket 10 is equipped with two micro switches 80, one of which is located below the connecting plate 50 and the other is located above the connecting plate 50. When the connecting plate 50 moves to the bottom, it triggers the micro switch 80 located below the connecting plate 50, which sends a signal to the control system of the mopping robot, allowing the mopping robot to know the position of the connecting plate 50. When the connecting plate 50 moves to the top, it triggers the bottom micro switch 80 located above the connecting plate 50, which sends a signal to the control system of the mopping robot, allowing the mopping robot to know the position of the top of the connecting plate 50, thus facilitating the mopping robot to accurately control the lifting and lowering of the mop assembly 22.

[0058] In this embodiment, the first driving component 41 is a motor, which can drive all the mop mechanisms 20 to lift and lower, saving space; at the same time, the lifting and lowering synchronization of all the mop mechanisms 20 is good; the second driving component 31 is also a motor, wherein one gearbox 32 can be equipped with one motor, or multiple gearboxes 32 can be equipped with one motor, and the specific transmission method can be selected according to actual needs, and is not limited here.

[0059] In practical applications, combine Figure 1 and Figure 2 As shown, when there are two mop mechanisms 20, the second drive unit 31 is a double-head motor. The two output shafts of the double-head motor are connected to the input shafts of the two gearboxes 32 respectively, and the two gearboxes 32 are set on opposite sides of the double-head motor. The first drive unit 41 and the double-head motor are both mounted on the bracket 10. The first drive unit 41 is set in front of the double-head motor. The connecting plate 50 and the lead screw 42 are set in front of the double-head motor and above the lead screw 42 and the first drive unit 41. The two ends of the connecting plate 50 are respectively located above the two gearboxes 32 and connected to the upper end of the rotating shaft 21 through the snap ring 90. The lead screw 42 is located in the middle position of the connecting plate 50. The guide rod 60 is located between the lead screw 42 and the gearbox 32. This layout makes the structure of the entire mopping device compact and convenient for component installation.

[0060] In another embodiment of this application, a mopping robot is provided, including the mopping device described above.

[0061] The mopping robot of this embodiment, by employing the aforementioned mopping device, drives the mop assembly 22 upward through the drive end of the lifting drive mechanism 40, preventing the mop assembly 22 from contacting and wetting the carpet after the mopping device moves onto the carpet, thus enabling the mopping robot to move freely on the carpet. Furthermore, through the connecting plate 50, the mopping device requires only one lifting drive mechanism 40 to move all the mop assemblies 22 upward, resulting in fewer parts, a simpler structure, and significantly reduced installation space for the lifting drive mechanism 40, thus reducing the overall size of the mopping device. Since the mopping device uses one lifting drive mechanism 40 to drive all the mop assemblies 22 upward, the synchronicity of the upward movement of the mop assemblies 22 is good. Additionally, the rotary drive... The drive end of the lifting mechanism 30 is slidably connected to the rotating shaft 21. During the process of the lifting drive mechanism 40 driving the rotating shaft 21 to rise and fall, interference between the rotating shaft 21 and the rotating drive mechanism 30 in the lifting direction is avoided. At the same time, the lifting drive mechanism 40 only needs to drive the mop mechanism 20 to rise and fall, without driving the rotating drive mechanism 30 to rise and fall. This makes the lifting of the mop mechanism 20 easier, and a smaller and less powerful lifting drive mechanism 40 can also be selected, further saving space and improving the overall structural compactness of the mopping robot. In addition, when the lifting mechanism lifts the mop assembly 22, the mop assembly 22 separates from the carpet. This can also solve the problem of large component damage caused by the sliding friction between the mop assembly 22 and the carpet when the mopping robot walks on the carpet.
