Description

Technical Field

[0001] This disclosure relates to the construction of accessories for floor mops, and more specifically to a mop cleaning device for floor mops. Background Technology

[0002] Autonomous mobile devices refer to intelligent mobile devices that autonomously perform preset tasks. These devices can move autonomously based on the results sensed by their sensing components. Currently, autonomous mobile devices typically include, but are not limited to, self-moving cleaning equipment (such as intelligent sweeping robots, intelligent mopping robots, and intelligent floor scrubbing robots), companion mobile robots (such as intelligent electronic pets and nanny robots), service mobile robots (such as reception robots in hotels, inns, and meeting venues), industrial inspection intelligent devices (such as power inspection robots and intelligent forklifts), and security robots (such as home or commercial intelligent security guard robots).

[0003] Autonomous mobile devices with mopping functions can be collectively referred to as mopping robots. Mopping robots include those with only mopping capabilities, or those combining mopping with other functions (such as sweeping). After a certain period of operation, the mop cloth accumulates a large amount of dirt due to continuous wet mopping, requiring timely cleaning. Manually cleaning the mop cloth is not only inefficient but also untimely, thus necessitating the development of automated mop cleaning devices. However, existing automated mop cleaning devices are relatively complex in structure and lack stable operation. Utility Model Content

[0004] In view of the problems of the prior art, the purpose of this disclosure is to provide a mop cleaning device for a floor mop, which can realize the automated cleaning of the mop with a relatively simple structure, thereby improving the mop cleaning efficiency and timeliness of the floor mop, and saving costs.

[0005] To achieve the above objectives, the present disclosure adopts the following technical solution.

[0006] This disclosure provides a mop cleaning device for a floor cleaning machine, comprising:

[0007] A base assembly, which is placed on a support surface and has guide rails;

[0008] A slide assembly, mounted on the base assembly, the slide assembly being capable of reciprocating along the guide rail, and the slide assembly having a guide groove; and

[0009] A drive assembly is mounted on the base assembly. The drive assembly has an insertion part that inserts into the guide slot. The insertion part and the guide slot cooperate to drive the slide assembly to perform the reciprocating motion.

[0010] In one alternative embodiment, the drive assembly includes a motor and a guide wheel, the guide wheel comprising a wheel body and a guide post fixed to each other, the wheel body being driven by the motor to rotate about its central axis, and the insertion portion extending linearly and arranged off-axis relative to the central axis of the wheel body.

[0011] In another alternative embodiment, the guide post is arranged off-axis with the wheel body, and the guide post always extends along a first direction parallel to the central axis, the first direction being perpendicular to the support surface.

[0012] In another alternative embodiment, the guide groove extends along a second direction perpendicular to the first direction, and the guide rail extends along a third direction perpendicular to both the first and second directions.

[0013] In another alternative embodiment, the slide assembly includes:

[0014] A guided component, mounted on the guide rail and capable of reciprocating along the guide rail; and

[0015] A slide plate, which is detachably mounted to the guided component.

[0016] In another alternative embodiment, the guided component includes a mounting portion and a driven portion that are fixed to each other.

[0017] A guide shaft, serving as the guide rail, is inserted through the mounting portion. A hook is formed on a first side of the mounting portion. The slide plate has a connecting portion corresponding to the hook. The connecting portion is mounted to the hook so that the slide plate and the mounting portion can be detachably assembled together.

[0018] The driven part is fixedly connected to the second side of the mounting part, and the guide groove is formed in the driven part.

[0019] In another alternative embodiment, the slide further includes a slide body, and the connecting portion is fixedly installed on the side edge of the slide body.

[0020] The board body has multiple protrusions and multiple through holes. The multiple protrusions are arranged at intervals on the top of the board body for contacting the mop cloth of the mopping machine. The through holes penetrate the board body along the height direction of the board body.

[0021] In another alternative embodiment, the slide further includes a plurality of support wheel assemblies, each of which includes an elastic plate and a roller. One end of the elastic plate is mounted to the bottom of the slide body, and the roller is rotatably mounted to the other end of the elastic plate. The slide is supported by the base assembly via the plurality of support wheel assemblies.

[0022] In another alternative embodiment, the slide assembly further includes a plurality of guide wheels mounted on the guided member in a manner rotatable relative to the guided member, the guided member contacting the base assembly via the plurality of guide wheels.

[0023] In another alternative embodiment, the motor is provided with a motor gear, the wheel body is formed with teeth and the wheel body is always meshed with the motor gear, so that the motor gear and the wheel body constitute a speed reduction transmission mechanism.

[0024] In another alternative embodiment, the base assembly includes a base and a guide seat that can be detachably assembled together.

[0025] The guide rail is fixed to the base, and

[0026] The guide seat is used to guide the mopping machine to position it at a position corresponding to the mop cloth and the mop plate assembly. The guide seat has a water trough, and the portion of the mop plate assembly used for cleaning the mop cloth is always located above the water trough.

[0027] In another alternative embodiment, the base has a drain outlet, and the guide seat has a water nozzle communicating with the drain outlet.

[0028] The bottom of the water tank has a water collection recess that is recessed downward relative to the rest of the bottom of the water tank, and the water spout communicates with the water collection recess; and / or the bottom of the water tank is configured to be inclined toward the side where the water spout is located.

[0029] By adopting the above technical solution, this disclosure provides a mop cleaning device for a floor cleaning machine. The mop cleaning device includes a base assembly, a mop plate assembly, and a drive assembly assembled together. Specifically, the base assembly is placed on a support surface and has a guide rail. The mop plate assembly is mounted on the base assembly and assembled with the guide rail, and the mop plate assembly is capable of reciprocating along the guide rail, and the mop plate assembly has a guide groove. The drive assembly is mounted on the base assembly, and the drive assembly has an insertion part that inserts into the guide groove. The insertion part and the guide groove cooperate to enable the mop plate assembly to reciprocate along the guide rail.

[0030] In this way, by utilizing the insertion part of the drive component and the guide groove of the slipper assembly, the slipper assembly can reciprocate stably and smoothly along the guide rail. Thus, a relatively simple structure is achieved, enabling the slipper assembly used for cleaning to reciprocate and effectively clean the mop. This mop cleaning device not only automates cleaning operations but also has relatively low cost, improved operational stability, and a longer lifespan. Attached Figure Description

[0055] Embodiments of this disclosure are described below with reference to the accompanying drawings. For ease of understanding, the elements shown in the drawings may include elements such as dimensions and scales that are expressed differently from actual dimensions and scales.

[0056] In this disclosure, unless otherwise specified, "upper" and "lower" refer to the upper and lower sides in the vertical direction, respectively, when the mop cleaning device according to this disclosure is placed on a horizontal support surface and in normal use. Furthermore, to clearly illustrate the technical solution of this disclosure, the terms "first direction," "second direction," and "third direction" are used to help describe the structural and relative positional features of each component. When the mop cleaning device according to this disclosure is placed on a horizontal support surface and in normal use, the first direction is a vertical direction perpendicular to the horizontal plane, and the second and third directions are two directions parallel to the horizontal plane and perpendicular to each other. Additionally, in this disclosure, the terms indicating location and direction are used only to clearly illustrate the structure and working process of the mop cleaning device according to this disclosure, but do not impose any particular limitations on the structure and / or usage state of the mop cleaning device.

[0057] In this disclosure, the term "off-axis" refers to the fact that the central axes of the two components are arranged offset from each other in a non-collinear manner; furthermore, "reciprocating motion" can include linear motion and curvilinear motion.

[0058] The following description, in conjunction with the accompanying drawings, describes a mop cleaning device for a floor cleaning machine according to this disclosure.

[0059] like Figure 1 As shown, a mop cleaning device for a floor cleaning machine according to an embodiment of the present disclosure includes a base assembly 1, a mop plate assembly 2, and a drive assembly 3 assembled together, which is capable of automatically cleaning a mop mop mopped on the mop plate assembly 2.

[0060] In this embodiment, the base assembly 1 can be placed on a horizontal support surface, which is typically the floor of a building interior. Figure 1 , Figure 2 and Figure 5 As shown, the base assembly 1 includes a guide rail 11, a base 12, and a guide seat 13 assembled together.

[0061] like Figure 1 and Figure 2 As shown, the guide rail 11 is fixedly mounted on the base 12 and stably supported by the base 12. Further, as... Figure 3 and Figure 4 As shown, the guide rail 11 is formed as a cylindrical guide shaft extending linearly in a third direction D3 parallel to the horizontal support surface. The cross-section of the guide shaft at any point in its extension direction is a circle with the same shape and size. In this way, the slide assembly 2 mounted on the guide rail 11 can be guided by the guide rail 11 to achieve reciprocating linear motion.

[0062] The bottom of the base 12 is designed to be placed directly on a horizontal support surface, such as... Figure 1 and Figure 2 As shown, the base 12 is used to support the guide rail 11 and other components. Therefore, the base 12 is provided with various connection structures and mounting structures for installing these other components. For example... Figure 2 As shown, the base 12 includes two side walls and a rear wall that stand upright relative to the bottom, forming a forward-opening chamber surrounded by the two side walls and the rear wall. The aforementioned connecting and mounting structures are all disposed within this chamber. Further, the base 12 has a drain outlet 12o communicating with the water tank 13c of the guide seat 13, which allows wastewater collected in the water tank 13c to be discharged to the outside of the mop cleaning device. The inner wall surface of each side wall of the base 12 is also provided with a snap-fit ​​groove 12c and a guide protrusion 121. The snap-fit ​​groove 12c of the base 12 engages with the snap-fit ​​protrusion 132 of the guide seat 13 for detachable connection between the base 12 and the guide seat 13. The guide protrusion 121 of the base 12 engages with the guided protrusion 133 of the guide seat 13 for guiding during the assembly and disassembly of the base 12 and the guide seat 13.

[0063] like Figure 1 and Figure 2As shown, the guide seat 13 and the base 12 are detachably assembled together. The guide seat 13 is used to guide the mop and position it corresponding to the mop head and mop plate assembly 2. For this purpose, a track for the mop to travel on can be provided on the top of the guide seat 13. To collect wastewater generated during the cleaning of the mop head, such as... Figure 2 As shown, the guide seat 13 has a water tank 13c, and the portion of the mop assembly 2 used for cleaning the mop (the main body 222 of the mop 22) is always located above the water tank 13c. Furthermore, the guide seat 13 has a water nozzle 131 extending toward the base 12 formed on its rear wall surrounding the water tank 13c. When the guide seat 13 and the base 12 are assembled in place, the water nozzle 131 is inserted into the drain outlet 12o of the base 12, so that the water tank 13c communicates with the drain outlet 12o via the water nozzle 131. Moreover, a water collection recess 13c1 is formed at the bottom of the water tank 13c, and the water collection recess 13c1 is configured to be recessed downwards relative to the rest of the bottom of the water tank 13c, and the water nozzle 131 communicates with the bottom of this water collection recess 13c1. This facilitates the collection of wastewater in the water tank 13c towards the location of the water nozzle 131, and then through the water nozzle 131 into the drain outlet 12o, so as to enter the collection device in the base 12. Furthermore, the bottom of the water tank 13c can also be configured to slope towards the side where the water nozzle 13c is located (the water tank 13c slopes downwards), which further facilitates the collection of wastewater in the water tank 13c towards the location of the water nozzle 131 for discharge. This not only facilitates guiding the mop to the predetermined position of the mop cleaning device (the position where the mop cloth of the mop corresponds to the body 222 of the mop plate 22), but also allows the wastewater cleaned from the mop to be collected in the water tank 13c for discharge. Further, as... Figure 2 As shown, corresponding to the shape and position of the snap-fit ​​groove 12c of the base 12, the side wall of the guide seat 13 is provided with snap-fit ​​protrusions 132; corresponding to the shape and position of the guide protrusions 121 of the base 12, the side wall of the guide seat 13 is provided with guided protrusions 133. Furthermore, the guide seat 13 forming the water tank 13c is configured to be detachably connected to the base 12, which facilitates the cleaning of the water tank 13c. This is because during the mop cleaning process, hair, debris, and other dirt attached to the mop may accumulate in the water tank 13c. Long-term lack of cleaning may cause blockage of the water nozzle 131, and even mold growth in the water tank 13c. Therefore, cleaning the guide seat 13 forming the water tank 13c after detaching it from the base 12 can effectively prevent the aforementioned blockages and mold growth.

[0064] It is understood that the structure and shape of the guide rail 11 are not limited to the guide shaft described above. As long as the guide rail 11 can guide the slide assembly 2 to achieve reciprocating motion, the guide rail 11 can adopt various different structures and shapes as needed. In other alternative solutions, the guide rail 11 can also be formed into a curved shape; in addition, the cross-sectional shape of the guide rail 11 can be formed into a polygonal shape, or even an irregular shape, etc., which can further prevent the slide assembly 2 from tilting during reciprocating motion along the guide rail 11. The structure and shape of the base 12 are not limited to the specific construction described above. As long as the base 12 can achieve the support function described above, the base 12 can adopt various different structures and shapes as needed. The structure and shape of the guide seat 13 are not limited to the specific construction described above. As long as the guide seat 13 forms a water tank 13c and can achieve a detachable connection with the base 12, the guide seat 13 can adopt various different structures and shapes as needed.

[0065] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the slide assembly 2 is mounted on the base assembly 1 and assembled with the guide rail 11, and the slide assembly 2 can reciprocate linearly along the guide rail 11. Specifically, the slide assembly 2 includes a guided member 21, a slide 22, and a guide wheel 23 assembled together.

[0066] like Figure 3 and Figure 4 As shown, the guided member 21 is mounted on the guide rail 11 and is capable of reciprocating linear motion along the guide rail 11. Specifically, the guided member 21 includes a mounting portion 211 and a driven portion 212 fixed to each other. The main body of the mounting portion 211 extends linearly along a third direction D3 and is inserted through the main body of the mounting portion 211 as a guide shaft of the guide rail 11. Further, the mounting portion 211 also includes a first side portion and a second side portion located on both sides of the main body. The first side portion is provided with two hooks 2111 protruding toward the slide plate 22. The two hooks 2111 are spaced apart on the third direction D3, and each hook 2111 is formed as a hook structure for the connecting portion 221 of the slide plate 22 to engage. The second side portion is fixedly connected to the driven portion 212, which extends along a second direction D2 perpendicular to the third direction D3. The driven portion 212 forms a guide groove 212c that opens toward the drive assembly 3, and the guide groove 212c also extends linearly along the second direction D2.

[0067] like Figure 3 and Figure 4 As shown, the slide plate 22 is detachably mounted to the guided member 21. Specifically, the slide plate 22 includes a connecting part 221, a plate body 222, and a plurality of support wheel assemblies 223.

[0068] like Figure 3 As shown, the connecting part 221 is fixedly installed on the side edge of the plate body 222 and stands upright relative to the plate body 222. The connecting part 221 forms a connecting mechanism that matches the hook shape of the hook 2111 of the mounting part 211, so that it can be easily connected to the hook 2111 in a disassembly and assembly manner. In addition, the connection structure formed by the connecting part 221 of the mop plate 22 and the mounting part 211 of the guided member 21 allows for easy detachable connection between the mop plate 22 and the guided member 21, which facilitates the cleaning of the mop plate 22. This is because during the cleaning of the mop, hair, debris, and other dirt attached to the mop may transfer to the mop plate 22. If it is not cleaned for a long time, too much dirt may accumulate on the mop plate 22, thereby reducing the cleaning effect of the mop plate 22 on the mop, and even causing mold to grow on the mop plate 22. Therefore, cleaning the mop plate 22 after removing it from the guided member 21 can effectively avoid the aforementioned problems such as reduced cleaning effect and mold growth.

[0069] like Figure 3 and Figure 4 As shown, the board body 222 has multiple protrusions 2221 and multiple through holes 222h. Except for areas where the multiple through holes 222h are avoided, the protrusions 2221 are arranged in an array across the entire top of the board body 222, meaning that the multiple protrusions 2221 are spaced apart on the top of the board body 222, creating a concave-convex structure on the top of the board body 222. This concave-convex structure is used to contact the mop cloth of the mopping machine, thereby repeatedly rubbing the mop cloth during the reciprocating linear motion of the mop assembly 2 to remove dirt from the mop cloth. The multiple through holes 222h are arranged spaced apart from each other, and each through hole 222h penetrates the board body 222 along its height direction (i.e., the vertical direction). In this embodiment, each through hole 222h is formed with a rectangular cross-section. Therefore, the mop plate 22 can effectively clean the mop head using the protrusion 2221, and the multiple through holes 222h can guide the wastewater flowing from the mop head into the water tank 13c formed by the mop cleaning device. Furthermore, the structure of the hook 2111 and the connecting part 221 makes it easy to install the mop plate 22 onto the mounting part 211 and also easy to remove the mop plate 22 from the mounting part 211, thus facilitating cleaning of the mop plate 22. In addition, the connection structure between the drive assembly 3 and the guided member 21 does not affect the cleaning operation of the mop plate 22 on the mop head of the floor cleaning machine.

[0070] like Figure 4As shown, multiple (four in this embodiment) support wheel assemblies 223 are arranged at intervals between each other on the bottom of the plate body 222. Each support wheel assembly 223 includes an elastic plate 2231 and a roller 2232. One end of the elastic plate 2231 is mounted to the bottom of the plate body 222. The other end of the elastic plate 2231 is raised relative to the plate body 222, and the roller 2232 is rotatably mounted to the other end of the elastic plate 2231. Thus, as Figure 1 As shown, with the main body 222 of the drag plate 22 positioned in the water tank 13c of the guide seat 13 of the base assembly 1, the drag plate 22 is supported by the guide seat 13 of the base assembly 1 via multiple support wheel assemblies 223. The multiple support wheel assemblies 223 not only allow the guide seat 13 to stably support the drag plate 22, but also enable close contact between the main body 222 of the drag plate 22 and the mop cloth using the elastic properties of the elastic plate 2231, and reduce the friction between the drag plate 22 and the base assembly 1 during relative movement using the rollers 2232.

[0071] like Figure 3 As shown, multiple (four in this embodiment) guide wheels 23 are mounted on the top of the driven portion 212 of the guided member 21. The guide wheels 23 are rotatable relative to the guided member 21, and the guided member 21 rolls into contact with the base assembly 1 via the multiple guide wheels 23. By using multiple guide wheels 23, not only can the skewness of the guided member 21 of the slide assembly 2 be prevented during its movement along the guide rail 11, but the frictional force generated during the movement of the guided member 21 relative to the base assembly 1 can also be reduced.

[0072] It is understood that the structure and shape of each component of the slide assembly 2 are not limited to the specific construction described above. As long as these components can achieve the functions described above, they can adopt various different structures and shapes as needed. In other optional solutions, the specific structure of the guided member 21 and the slide 22, the detachable connection structure between the guided member 21 and the slide 22, and the number and arrangement of the guide wheels 23 can all be adjusted as needed.

[0073] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the drive assembly 3 is mounted on the base assembly 1. Specifically, the drive assembly 3 includes a motor 31 and a guide wheel 32. The motor 31 can be a DC motor or an AC motor. DC motors have advantages such as good speed regulation performance and large starting torque, while AC motors have advantages such as simple structure and reliable operation. In practical applications, the appropriate type of motor 31 can be selected according to specific needs and manufacturing costs. The motor 31 is provided with a motor gear 311 that is always meshed with the guide wheel 32. Further, the guide wheel 32 includes a wheel body 321 and a guide post 322 that are fixed to each other. The wheel body 321 has teeth and is always meshed with the motor gear 311. The wheel body 321 can be driven by the motor 31 to rotate around its central axis relative to the base assembly 1. Thus, the motor gear 311 and the wheel body 321 constitute a reduction transmission mechanism, which can increase the torque of the motor 31 and transmit it to the guide wheel 32. This not only ensures the smooth reciprocating motion of the slide assembly 2, but also reduces the output power of the motor 31, thereby reducing the cost of the motor 31 itself. In this embodiment, the guide post 322 is arranged off-axis with the wheel 321, and the guide post 322 always extends along a first direction D1 parallel to the central axis. The guide post 322 has an insertion part 322p that inserts into the guide groove 212c. The insertion part 322p is arranged off-axis with the wheel 321, so that by using the cooperation of the insertion part 322p and the guide groove 212c, the rotation of the wheel 321 is converted into the reciprocating linear motion of the mop assembly 2 along the guide rail 11. In this way, the drive assembly 3 can not only smoothly drive the mop assembly 2 to perform reciprocating linear motion, but also helps to further simplify the specific structure of the drive assembly 3 of the mop cleaning device.

[0074] It is understood that the structure and shape of each component of the drive assembly 3 are not limited to the specific construction described above. As long as these components can achieve the functions described above, they can adopt various different structures and shapes as needed. In other alternative solutions, the motor 31 can drive the guide wheel 32 to rotate via other transmission mechanisms such as a belt drive mechanism. Furthermore, the guide post 322 can be configured such that the insertion part 322p extends in a straight line and the insertion part 322p is arranged off-axis with the wheel body 321. In this case, the shape of the part of the guide post 322 other than the insertion part 322p can be changed as needed. By adopting such a solution, the reciprocating linear motion of the slide assembly 2 can be achieved as long as the motor 31 rotates in one direction. Further, in other alternative solutions, the drive assembly 3 can also adopt other mechanisms such as a crankshaft slider mechanism (where the crank is the rotating driving member and the slider is the reciprocating driven member) or a cam-pushrod mechanism (where the cam is the rotating driving member and the pushrod is the reciprocating driven member) to achieve the same function.

[0075] By adopting the above technical solution, the motor 31 drives the wheel body 321 of the guide wheel 32 to rotate. Utilizing the guide post 322 of the guide wheel 32, which is off-axis to the wheel body 321, and the guide groove 212c of the drag plate assembly 2, the rotation of the wheel body 321 can be stably and smoothly converted into the reciprocating linear motion of the drag plate assembly 2 along the guide rail 11. Thus, the reciprocating linear motion of the drag plate 22 is achieved with a relatively simple structure, thereby cleaning the mop with the drag plate 22. This mop cleaning device not only achieves automated cleaning operations but also has relatively low cost, improved operational stability, and a longer lifespan. Furthermore, in the above embodiments, the guide post 322 always extends along a first direction D1 parallel to the central axis (perpendicular to the horizontal support surface), the guide groove 212c extends along a second direction D2 perpendicular to the first direction D1, and the guide rail 11 extends along a third direction D3 perpendicular to both the first and second directions D1 and D2. This structure helps optimize the overall layout of the mop cleaning device and simplifies its overall construction.

[0076] Furthermore, in the mop cleaning device according to this disclosure, on the one hand, the guide seat 13 forming the water trough 13c has a detachable connection structure with the base 12, which facilitates the cleaning of the water trough 13c. This is because during the mop cleaning process, hair, debris, and other dirt attached to the mop may accumulate in the water trough 13c. Long-term neglect of cleaning may cause blockage of the water nozzle 131, or even mold growth in the water trough 13c. Therefore, cleaning the guide seat 13 forming the water trough 13c after detaching it from the base 12 can effectively prevent the aforementioned blockage and mold growth. On the other hand, the mop plate 22 has a detachable connection structure with the guided component 21, which facilitates the cleaning of the mop plate 22. This is because during the mop cleaning process, hair, debris, and other dirt attached to the mop may transfer to the mop plate 22. Long-term neglect of cleaning may cause too much dirt to accumulate on the mop plate 22, thereby reducing the cleaning effect of the mop plate 22 on the mop, or even mold growth on the mop plate 22. Therefore, cleaning the slide plate 22 after removing it from the guide member 21 can effectively avoid the aforementioned issues such as reduced cleaning effectiveness and mold growth.

[0077] The following describes the operating method of the above-mentioned mop cleaning device.

[0078] With the mop robot parked at the predetermined position of the mop cleaning device, the mop cloth is positioned on top of the main body 222 of the mop plate 22 and abuts against the top of the main body 222. At this time, the mop cleaning device is activated, the motor 31 starts, and drives the guide wheel 32 to rotate. During the rotation of the guide wheel 32, the guide post 322 rotates (revolves) around the central axis of the wheel body 321. Utilizing the cooperation between the guide post 322 and the guide groove 212c, the rotation of the guide post 322 is converted into the reciprocating linear motion of the mop plate 22, causing the uneven structure formed on the top of the mop plate 22 to repeatedly rub against the mop cloth. Simultaneously, the mop robot can deliver cleaning fluid (e.g., water) to the mop cloth, thereby using the aforementioned friction and the cleaning action of the cleaning fluid to remove dirt from the mop cloth. The removed dirt, along with the cleaning fluid, enters the water tank 13c and is ultimately discharged to the outside of the mop cleaning device through the drain outlet 12o.

[0079] It should be understood that the above embodiments are merely exemplary and not intended to limit this disclosure. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this disclosure without departing from the scope of this disclosure. The following supplementary descriptions are provided regarding the technical solutions of this disclosure.

[0080] i. The above specific embodiments illustrate that the mop cleaning device according to this disclosure is applicable to all autonomous mobile devices with mopping functions, typically various self-moving cleaning devices. Specifically, the self-moving cleaning device may include a main body and a cleaning mechanism assembled together. The main body may include a main unit that is circular in a top view. The shape of the main unit is not limited to this; alternatively, the main unit may have other shapes in a top view, such as square, elliptical, D-shaped, etc. When the self-moving cleaning device according to the embodiments of this disclosure is in normal operation, the bottom surface of the main unit is opposite to the surface to be cleaned, and the bottom surface of the main unit is parallel to the surface to be cleaned. Here, "parallel" includes not only the geometric parallel relationship between the bottom surface of the main unit and the travel surface, but also the case where the two are approximately parallel. The above "approximately" means that the parallel relationship between the two can be determined to be valid within a reasonable error range recognized by those skilled in the art. In addition, other components of the self-moving cleaning device may be disposed in the main unit. In order to support and protect other components, most of the structure of the self-moving cleaning device is installed inside or on the surface of the main unit, or is connected to the main unit. The self-moving cleaning device may also include a processing unit and sensing components in the main unit. Furthermore, the cleaning mechanism of this self-propelled cleaning device may also include a dry cleaning component, such as a main brush, and a wet cleaning component, including a mop, etc. Thus, the processing unit can obtain environmental parameters through sensing components, and based on the obtained environmental parameters, the processing unit can control the entire self-propelled cleaning device to move autonomously on the surface to be cleaned, thereby performing cleaning operations on the surface to be cleaned using the dry and / or wet cleaning components. In different operating modes, the cleaning operations include, but are not limited to, one or more of the following: sweeping, mopping, and vacuuming.

[0081] Furthermore, the aforementioned self-moving cleaning device can move autonomously according to a preset control scheme in its processing unit. The surface to be cleaned where the self-moving cleaning device moves autonomously can be a plane or a curved surface with a large radius of curvature, typically such as the floor of each room in a building. The term "processing unit" in this disclosure is a general term and does not limit the type, number, or form of the processing units. Specifically, the processing unit can be one or more of MCU, DSP, FPGA, and GPU, or other hardware chips, processors, or software algorithms with data processing and computing capabilities. Further, the processing unit can be a unified, single processor for the autonomous mobile device, or it can be a collection of multiple processing units. The connection method, function, and computing power allocation of the multiple processing units can be adjusted as needed. For example, in one optional scheme, a first processing unit and a second processing unit can be included. In this case, the first and second processing units collectively implement the various functions of the aforementioned processing unit. In addition, the processing unit of the self-moving cleaning device can receive parameters from the sensing components and perform relevant control on the self-moving cleaning device through a preset program stored in the storage unit. In this disclosure, the data, information, and programs required by the processing unit during processing can be stored in the storage unit and retrieved from the storage unit as needed. The processing unit can also store the processed data and information back into the storage unit. The storage unit can be RAM, ROM, or other devices and / or equipment with storage functions, such as cloud / server / mobile terminal connected via wired / wireless network.

[0082] To enable autonomous movement of the self-moving cleaning device, the main body of the aforementioned self-moving cleaning device may further include a wheel assembly. The wheel assembly may be mounted on the main unit and protrude from the bottom surface of the main unit, used to drive the entire self-moving cleaning device to move on the travel surface under the control of the processing unit. By causing the two wheels (drive wheels) of the wheel assembly to rotate at the same speed and in the same direction (e.g., simultaneously clockwise or simultaneously counterclockwise), the self-moving cleaning device can be driven to move linearly in the forward direction; by causing the two wheels of the wheel assembly to rotate at different speeds and / or in different directions (e.g., one wheel rotates clockwise while the other rotates counterclockwise), the self-moving cleaning device can be driven to turn in a direction different from the forward direction. The self-moving cleaning device may also include casters (not shown) mounted on the main unit, so that regardless of how the wheels roll on the travel surface, the casters can support the entire self-moving cleaning device.

[0083] ii. It is understood that the mop cleaning device according to this disclosure can be equipped with a charging system compatible with a mopping machine. Furthermore, the mop cleaning device can be equipped with other supporting systems such as a water supply system, a self-cleaning system, and / or a dust collection system. Thus, the mop cleaning device can integrate all the functions of an existing base station, thereby serving as a base station for a mopping machine.

[0084] iii. For example Figure 1 and Figure 5 As shown, in order to smoothly assemble the drive assembly 3 onto the base assembly 1, for example, the motor 31 can be assembled onto the corresponding mounting structure of the base 12 from the top, and the guide wheel 32 can be mounted onto the mounting structure from the bottom, so that the guide wheel 32 meshes with the motor gear 311. Similarly, the installation of other components can adopt different installation methods depending on the specific situation.
