[0002] Currently, cleaning robots include floor-sweeping robots, mopping machines (robots with mopping functions but without sweeping functions), double-rotating disk floor-sweeping machines, floor washing machines, etc. Some cleaning robots are provided with mops at the bottom. The cleaning robot can perform wet cleaning on the surface to be cleaned (such as the ground or the tabletop) by contacting the mop with the surface to be cleaned in the mopping mode. During the process of the cleaning robot moving forward during the cleaning work and / or during the process of the cleaning robot driving the mop to lift and lower, due to the presence of obstacles on the surface to be cleaned, the mop is likely to touch the obstacles, which may cause the mop to malfunction or even stop working. This not only affects the working efficiency of the cleaning robot but also reduces the user experience. Summary of the Invention

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0056] The cleaning assembly 20 of the cleaning device includes a rotating mop 22. For the convenience of disassembly, replacement, or maintenance of the mop 22, the mop 22 is connected to the drive mechanism 50 installed in the cleaning device by magnetic attraction or other detachable means. To ensure that the mop 22 can better fit the surface to be cleaned to improve the cleaning effect, when the cleaning device cleans the surface to be cleaned through the mop 22, there is usually a certain gap between the mop 22 and the bottom surface of the cleaning device. In some cleaning device products, this gap can always exist between the mop 22 and the cleaning device. In some other cleaning device products, the drive mechanism 50 of some cleaning devices is a mechanism that can drive the mop 22 to lift and lower. Then, when the cleaning device starts the cleaning mode, it will control the drive mechanism 50 to first lower the mop 22 to the cleaning position close to the surface to be cleaned, and after the cleaning is over, control the drive mechanism 50 to lift the mop 22 to a position away from the surface to be cleaned and off the ground. Among them, when the mop 22 is in the cleaning position, there will be a relatively large gap between it and the bottom surface of the cleaning device. Regardless of the above-mentioned cleaning device, the gap between the mop 22 and the bottom surface of the cleaning device or the gap that exists during the process of the mop 22 descending from the off-the-ground position to the cleaning position will cause some low obstacles (such as electronic scales, flat household items) or obstacles within a preset height range to easily rub against the mop 22 along the gap, resulting in the mop 22 being stuck by the obstacles, leading to a decrease in rotational speed or even a direct stop, and even the risk of being disassembled and detached from the cleaning device. Especially when the mop 22 is connected to the drive mechanism 50 by magnetic attraction, the risk of detachment from the cleaning device is particularly high.

[0057] In view of the above problems, this embodiment provides a cleaning device. Please refer to Figures 1 to 6, the cleaning device includes a main body 10, a cleaning assembly 20, and a shielding member 30. An installation space is provided inside the main body 10 for installing and supporting other components of the cleaning device. Along a first direction, the cleaning assembly 20 is installed at the bottom of the main body 10, and there is a first gap 23 between the surface of the main body 10 close to the cleaning assembly 20 and the cleaning assembly 20. Wherein, the first direction is the height direction of the main body 10, that is Figure 1 the direction indicated by the arrow X in the figure. The shielding member 30 is disposed on one side of the main body 10 close to the cleaning assembly 20. Along the traveling direction of the cleaning device, the shielding member 30 is located in front of the cleaning assembly 20, and the shielding member 30 is used to shield the first gap 23. Thus, the shielding member 30 can prevent obstacles from entering the first gap 23 and rubbing against the cleaning assembly 20, avoiding the cleaning assembly 20 from being stuck by obstacles or detaching from the cleaning device. For example, during the process of the cleaning device driving the cleaning assembly 20 to travel, or during the process of the cleaning assembly 20 rising to a position off the ground or descending to a cleaning position under the drive of the drive mechanism 50, the shielding member 30 can block the obstacles, avoiding the cleaning assembly 20 from being rubbed by the obstacles.

[0058] In this embodiment, the cleaning device includes a main body 10, a cleaning assembly 20, and a shielding member 30. The main body 10 provides an installation space and a protective support function for other components of the cleaning device. The cleaning assembly 20 is installed at the bottom of the main body 10, and the cleaning assembly 20 can clean the surface to be cleaned under the drive and control of the cleaning device. There is a first gap 23 between the surface of the main body 10 close to the cleaning assembly 20 and the cleaning assembly 20. This first gap 23 exists to ensure that the cleaning assembly 20 can be closely attached to the surface to be cleaned during the cleaning process. The shielding member 30 is disposed on one side of the main body 10 close to the cleaning assembly 20 and can shield the first gap 23. Thus, since the first gap 23 is shielded by the shielding member 30, it is not easy for obstacles (especially obstacles whose shape can penetrate into the first gap 23) to enter the first gap 23 and rub or get stuck to the cleaning assembly 20, avoiding the cleaning assembly 20 from malfunctioning or detaching from the cleaning device due to being rubbed or stuck by obstacles. Therefore, in this application, by using the shielding member 30 to shield the first gap 23 between the cleaning assembly 20 and the main body 10, the stability and reliability of the cleaning assembly 20 during operation can be improved, thereby ensuring the working efficiency of the cleaning robot and providing a good user experience.

[0059] The cleaning device in this embodiment may include a sweeping robot, a mopping machine (a robot with mopping function but without sweeping function), a double-rotating sweeping machine, a floor washer, etc.

[0060] In some embodiments, the shielding member 30 may include one or more flap structures, and one or more flap structures may be disposed around the cleaning assembly 20 to cover and shield the first gap 23. The shielding member 30 may also be a protective net structure.

[0061] As shown Figures 1 to 3 in the figure, the surface of the main body 10 close to the cleaning component 20 includes a first area 101, and the cleaning component 20 is located within the first area 101. Along the first direction, the distance from the first area 101 to the side of the cleaning component 20 close to the main body 10 is the height H of the first gap. The shielding member 30 includes a convex structure 31, and along the traveling direction of the cleaning device, the convex structure 31 protrudes from the front side of the first area 101, and there is a first distance between the convex structure 31 and the cleaning component 20, so as to avoid interfering with the movement of the cleaning component 20. Among them, the traveling direction of the cleaning device is the Figure 1 direction indicated by the arrow Y in the figure. Along the first direction, the maximum distance from at least a part of the convex structure 31 away from the bottom of the main body 10 to the first area 101 is greater than or equal to H. That is, only a part of the convex structure 31 may have a maximum distance to the first area 101 greater than H, or the maximum distance of all parts may be greater than H. It should be noted that when the cleaning device is placed on the surface to be cleaned, the bottom of the convex structure 31 away from the main body 10 is specifically the lowest vertex of the convex structure 31 away from the main body 10. The maximum distance from the side of the convex structure 31 away from the main body 10 to the first area 101 is the maximum convex height of the convex structure 31 protruding from the surface of the first area 101. Thus, in this embodiment, by making the maximum convex height of the convex structure 31 greater than or equal to the height H of the first gap 23 along the first direction, the first gap 23 is shielded. Whether the convex structure 31 is installed on the main body 10 or integrally formed with the main body 10, the assembly is efficient and convenient. The convex structure 31 protrudes from one side of the first area 101, which can not only block obstacles but also does not increase the structural complexity of the cleaning device.

[0062] As shown Figure 5 in the figure, the cleaning component 20 includes a tray 21 and a mop 22. The tray 21 is installed in the first area 101, and the mop 22 is arranged on the surface of the tray 21 away from the main body 10. When the cleaning device further includes a driving mechanism 50, the driving mechanism 50 is installed inside the main body 10 and connected to the tray 21. The driving mechanism 50 may include a driving member 51 and a transmission component 52. The transmission component 52 is connected to the driving member 51 and at least partially extends out of the main body 10 and is connected to the tray 21, and the tray 21 can drive the mop 22 to rotate under the drive of the driving member 51 to clean the surface to be cleaned.

[0063] In this embodiment, the cleaning component 20 is detachably connected to the main body 10. In this regard, since the cleaning device is provided with a shielding member, it is not easy for obstacles to enter the first gap 23 and scrape off the cleaning component 20. Among them, the tray 21 of the cleaning component 20 and the transmission component 52 can be detachably connected by a magnetic member, or can be detachably connected together by other clamping structures.

[0064] Along the traveling direction of the cleaning device, a transition surface 3100 is provided on the front side of the convex structure 31 away from the cleaning assembly 20. Along the first direction, there is a third spacing between the transition surface 3100 and the first region 101, and along the traveling direction of the cleaning device, the third spacing gradually decreases in the direction away from the cleaning assembly 20. Thus, the transition surface 3100 forms an inclined surface that is inclined in the direction away from the cleaning assembly 20, that is, the horizontal plane where the transition surface 3100 is located gradually rises in the direction away from the cleaning assembly 20, so that a smoothly transitioning surface structure is formed on the side of the convex structure 31 away from the cleaning assembly 20. Thus, during the movement of the cleaning device, the transition surface 3100 can play a certain buffering role in the collision between the convex structure 31 and the obstacle, dispersing the collision force exerted by the obstacle on the convex structure 31, thereby improving the service life of the convex structure 31. Along the first direction, the projected outer contour of the transition surface 3100 is arc-shaped, rectangular, or some other irregular shape, and this embodiment does not make a unique limitation on this.

[0065] Secondly, to improve the structural strength of the convex structure 31, in this embodiment, a connecting surface 3101 can also be provided between the transition surface 3100 and the edge of the convex structure 31 close to the cleaning assembly 20. The connecting surface 3101 connects the transition surface 3100 and the side of the convex structure 31 close to the cleaning assembly 20. Along the traveling direction of the cleaning device, the connecting surface 3101 makes there be a certain thickness between the transition surface 3100 of the convex structure 31 and the edge of the convex structure 31 close to the cleaning assembly 20, thereby being able to improve the overall structural strength of the convex structure 31. The connecting surface 3101 can be one of a convex arc surface, a plane, a concave surface, etc., or a surface structure composed of at least one of a convex arc surface, a plane, a concave surface and at least one of the other three, and this embodiment does not make a unique limitation on this. Secondly, a smoothly transitioning rounded corner surface can also be provided between the connecting surface 3101 and the transition surface 3100, thereby improving the roundness of the overall shape of the convex structure 31 and avoiding scratching furniture items, etc.

[0066] In some embodiments, when the convex structure 31 is provided with the raised portion 312 mentioned below, along the traveling direction of the cleaning device, the transition surface 3100 can be provided on the side of the convex structure 31 and / or the raised portion 312 thereon away from the cleaning assembly 20, so as to reduce the force generated by the direct collision between the convex structure 31 and / or the raised portion 312 and the obstacle through the transition surface 3100.

[0067] In this embodiment, please refer to Figures 1 to 5 , there is a first spacing between the convex structure 31 and the tray 21. Thus, during the rotation of the tray 21, the boss 311 will not interfere with the rotation of the tray 21.

[0068] Along the first direction, a raised portion 312 protrudes from the surface of the raised structure 31 away from the main body 10. The raised portion 312 is located on the side of the raised structure 31 close to the cleaning assembly 20, and specifically may be located at the edge of the raised structure 31 close to the tray 21. The maximum distance from the bottom of the raised structure 31 away from the main body 10 to the first region 101 is the distance from one end of the raised portion 312 away from the main body 10 to the first region 101. Among them, both the raised structure 31 and the raised portion 312 thereon extend along the second direction (such as Figure 1 the direction indicated by the arrow Z in

[0069] ), and there is a second spacing between the opposite ends of the raised structure 31 along the second direction and the raised portion 312. That is to say, in this embodiment, the raised structure 31 and the raised portion 312 thereon can mainly be used to block obstacles. Among them, the raised structure 31 raises the raised portion 312 to a relatively high height from the first region 101, enabling the raised portion 312 to block more types and sizes of obstacles. At the same time, since there is a second spacing between the opposite ends of the raised structure 31 and the raised portion 312, the region where the raised structure 31 is misaligned with the raised portion 312 along the second direction is closer to the first region 101 relative to the raised portion 312. Thus, during the process of the cleaning device driving the cleaning assembly 20 to move forward, while blocking obstacles through the raised portion 312, the region where the raised structure 31 is misaligned with the raised portion 312 can reduce the obstacle-crossing difficulty of the cleaning device and improve the smoothness of the cleaning device during the moving process. The raised portion 312 can be arranged on the raised structure 31 through connection methods such as clamping and welding. The raised portion 312 can also be integrally arranged on the surface of the raised structure 31, thereby reducing the assembly steps of the main body 10 and further improving the assembly efficiency of the cleaning device.

[0070] The raised structure 31 specifically includes at least one of the structural forms such as a boss 311, a convex block, and a convex hull, and the projection of the edge of the raised structure 31 of the above structure close to the cleaning assembly 20 along the first direction can be an arc shape adapted to the outer peripheral shape of the tray 21.

[0071] The cleaning assembly 20 includes at least two groups. When there are two groups, the cleaning device is a double-rotating disk cleaning structure, so as to improve the cleaning efficiency and effect on the surface to be cleaned through at least two groups of cleaning assemblies 20. Such as Figures 1 to 2 shown, at least two groups of cleaning assemblies 20 are arranged along the second direction. The raised structure 31 includes at least two, and at least two raised structures 31 are integrally formed and are respectively arranged in one-to-one correspondence with at least two groups of cleaning assemblies 20. Thus, the first gap 23 between at least two groups of cleaning assemblies 20 and the main body 10 is blocked by the raised structure 31, improving the reliability of at least two groups of cleaning assemblies 20.

[0072] In some embodiments, the raised portions 312 on the raised structure 31 may also include at least two, and the at least two raised portions 312 are respectively arranged in one-to-one correspondence with at least two sets of cleaning components 20, so that at least two sets of cleaning components 20 are not easily scratched by obstacles. Along the traveling direction of the cleaning device, the portion of the raised structure 31 between two adjacent raised portions 312 extends toward the minimum gap between two adjacent sets of cleaning components 20. That is to say, along the traveling direction of the cleaning device, the portion of the raised structure 31 between two adjacent raised portions 312 is an extension portion 111 extending backward, and the extension portion 111 can block the first gap 23 between two adjacent sets of cleaning components 20 and the main body 10, and make the arrangement of the raised structure 31 and at least two sets of cleaning components 20 at the bottom of the main body 10 more compact and beautiful. Secondly, along the first direction, the distance from the end of the extension portion 111 away from the main body 10 to the first area 101 is also smaller than the distance from the end of the raised portion 312 away from the main body 10 to the first area 101, thereby reducing the obstacle-crossing difficulty of the cleaning device in this area. In some embodiments, the raised structure 31 does not have an extension portion 111 corresponding to the area between two adjacent sets of cleaning components 20. As Figure 7 shown, the side wall structure of the middle area of the raised structure 31 (such as the area between the first cleaning component 201 and the second cleaning component 202) close to the cleaning component 20 is a straight-line side wall structure.

[0073] When there is a first gap 23 between the cleaning component 20 and the main body 10, since the cleaning component 20 can be closely attached to the surface to be cleaned, to prevent the raised structure 31 and / or its raised portion 312 from being too high and rubbing against the surface to be cleaned, along the first direction, the distance from the end of the cleaning component 20 away from the main body 10 to the first area 101 is greater than the maximum distance from the end of the raised structure 31 away from the first area 101 to the first area 101. Thus, during the process of the cleaning component 20 cleaning the surface to be cleaned, the raised structure 31 will not contact the surface to be cleaned, nor will it rub against the surface to be cleaned, thereby avoiding the raised structure 31 and / or its raised portion 312 from scratching the surface to be cleaned and / or itself and generating friction noise, etc., and improving the service life of the raised structure 31.

[0074] When the mop 22 is relatively thick, in this embodiment, the bottom vertex of the raised structure 31 away from the main body 10 (such as the top position of the end of the raised portion 312 away from the main body 10) only needs not to exceed the thickness area when the mop 22 is attached to the surface to be cleaned. However, since the mop 22 is easily worn and thinned after being used for a long time, there is a risk that the raised structure 31 will contact the surface to be cleaned after the mop 22 becomes thinner (such as when it has a raised portion 312, the raised portion 312 is likely to contact the surface to be cleaned). In this regard, to further ensure that the raised structure 31 will not scratch the surface to be cleaned, as Figure 4As shown, along the first direction, the maximum distance from the end of the convex structure 31 away from the main body 10 (i.e., the vertex at the bottom end of the convex structure 31) to the first region 101 is L1, and the distance from the surface of the tray 21 away from the main body 10 to the first region 101 is L2. L1 is not greater than L2 (i.e., L1 ≤ L2), so that the convex structure 31 will not contact the surface to be cleaned. Even if the mop 22 becomes thinner due to long-term use, it will not cause the convex structure 31 to scrape the surface to be cleaned. Preferably, L1 is less than L2, thereby further reducing the risk of the convex structure 31 contacting the surface to be cleaned.

[0075] Secondly, along the first direction, the distance from the surface of the cleaning assembly 20 close to the main body 10 to the first region 101 is the height H of the first gap 23. When the cleaning assembly 20 includes the tray 21, H is specifically the distance from the surface of the tray 21 close to the main body 10 to the first region 101. H is less than L1, so that the convex structure 31 can completely block the height region of the first gap 23 along the first direction.

[0076] Along the first direction, the projected outer contour of the raised portion 312 is an arc-shaped strip structure, and the central angle of the raised portion 312 is α (such as Figure 2 the included angle α shown). α satisfies the relationship: 49° ≤ α ≤ 79°. The central angle is the included angle formed by the radii passing through the opposite ends of the raised portion 312 along its arc length direction. In this embodiment, by making the central angle of the arc-shaped raised portion 312 within the above range, the arc length of the raised portion 312 is set within a reasonable range, so that the arc length of the raised portion 312 is not too short to reduce the blocking rate of obstacles, nor will it increase the obstacle-crossing difficulty of the cleaning device due to too long arc length. In other words, when the central angle is within the above range, the raised portion 312 has a high blocking rate for obstacles and enables the cleaning device to better cross obstacles. The specific size of this central angle can include one of 49°, 50°, 51°, 52°, 52.5°, 53°, 56°, 56.7°, 58°, 59°, 60°, 61°, 64°, 66°, 67°, 68°, 70°, 71°, 72°, 74°, 75°, 77°, 78°, 79°, etc., or any other angular value between 49° and 79°. At this time, the side wall of the convex platform 311 on the side close to the tray 21 relative to the raised portion 312 and the portion between two adjacent raised portions 312 are both arc-shaped structures, and the edge of the raised portion 312 close to the tray 21 is in the same plane as the side wall, so that the overall structure of the shielding member 30 is more tidy and beautiful.

[0077] The cleaning device in this embodiment further includes a middle sweeping component 40. Along the first direction, the middle sweeping component 40 is installed at the bottom of the main body 10. Along the traveling direction of the cleaning device, the middle sweeping component 40 is located on the side of the convex structure 31 away from the cleaning component 20. Thus, during the traveling of the cleaning device, the middle sweeping component 40 first sweeps the surface to be cleaned, thereby reducing the cleaning pressure of the cleaning component 20 on the surface to be cleaned, and also avoiding the accumulation of some garbage in the area between the convex structure 31 and the cleaning component 20, and making the layout at the bottom of the cleaning device more compact and with high space utilization rate. The middle sweeping component 40 may include a cover plate structure and a roller brush. The roller brush is installed at the bottom of the main body 10 through the cover plate structure, and the roller brush is also connected to a driving component installed in the main body 10 to rotate and sweep the garbage under the drive of the driving component. The cleaning device collects the swept garbage into the dust box through the dust box installed in the main body 10.

[0078] As Figure 6 shown, the main body 10 in this embodiment includes a top shell 11 and a bottom shell 12. Along the first direction, the bottom shell 12 is covered and arranged at the bottom of the top shell 11. The top shell 11 and the bottom shell 12 can enclose and form an installation cavity for installing other components of the cleaning device (such as a dust box, a clean water box, a control board, electrical components, etc.). A first groove 121 is provided on one side of the bottom shell 12 close to the top shell 11. The first groove 121 is recessed in the direction away from the top shell 11 to form a convex structure 31 on the surface of the bottom shell 12 away from the top shell 11. Thus, in this embodiment, while forming the convex structure 31 through the setting of the first groove 121, the space size of the installation cavity can also be increased, thereby providing enough space for other components to be installed and improving the space utilization rate of the cleaning device. The first groove 121 and the convex structure 31 can be obtained by stamping on the bottom shell 12, saving the processing materials of the bottom shell 12 and being efficient and convenient in processing.

[0079] The cleaning device in this embodiment further includes a driving mechanism 50. The driving mechanism 50 is installed in the main body 10 and connected to the cleaning component 20. The driving mechanism 50 is at least used to drive the cleaning component 20 to move along a first direction to a first position close to the main body 10 and a second position away from the main body 10. The second position is closer to the surface to be cleaned than the first position. The first position is the ground clearance position mentioned above in this embodiment, and the second position is the cleaning position mentioned above. When the cleaning component 20 is located at the second position, there is a first gap 23 between the cleaning component 20 and the main body 10. When the cleaning component 20 is located at the first position, along the first direction, the distance from the surface of the cleaning component 20 away from the main body 10 to the first area 101 is less than the maximum distance from the convex structure 31 to the first area 101. Thus, when the cleaning component 20 does not need to mop the floor, the cleaning component 20 can be accommodated in the groove surrounded by the convex structure 31 (the first area 101 is the bottom surface of the groove), so as to protect the cleaning component 20. Secondly, regardless of whether there is a gap between the cleaning component 20 and the main body 10 when the cleaning component 20 is located at the first position, since this gap will be blocked by the blocking member 30, the cleaning component 20 will not be scratched off by an obstacle when it is located at the first position. When the cleaning component 20 is at any lifting position between the second position and the first position, in view of the fact that the blocking member 30 can block the first gap 23 when it is located at the second position, the lifting position will also be blocked by the blocking member 30. Therefore, the cleaning component 20 will not be scratched or stuck by an obstacle during the lifting or lowering process.

[0080] When the driving mechanism 50 includes a driving member 51 and a transmission component 52 to drive the cleaning component 20 to rotate, in order to realize the lifting of the cleaning component 20, the transmission component 52 may include a first abutting member and a second abutting member. The first abutting member connects the driving member 51 and the second abutting member, and the second abutting member connects the cleaning component 20. A track surface is provided on the second abutting member, and the first abutting member can movably abut on the track surface. The driving member 51 is configured to drive the first abutting member to rotate so that the first abutting member moves on the track surface, so as to lift or lower the cleaning component 20 relative to the main body 10.

[0081] In this embodiment, the cleaning component 20 includes at least one set of first cleaning components 201. The first cleaning components 201 can also be at least two sets, and at least two sets of first cleaning components 201 can be arranged along a second direction. Such as Figure 8As shown, the first cleaning assembly 201 is movable relative to the main body 10 between a retracted position and an extended position. When there are two groups, the cleaning device is a device with a double-rotating disk structure having an extended edge cleaning function. When the first cleaning assembly 201 is in the extended position, the portion located outside the edge contour of the main body 10 has a first volume, and when the first cleaning assembly 201 is in the retracted position, the portion located outside the edge contour of the main body 10 has a second volume, and the first volume is greater than the second volume. Among them, when the first cleaning assembly 201 is in the retracted position, the first cleaning assembly 201 may be entirely located inside the edge contour of the main body 10, or at least partially located inside the edge contour of the main body 10 and at least partially located outside the edge contour of the main body 10. In this regard, this embodiment does not make a unique limitation.

[0082] Among them, along the second direction, the main body 10 has a swing area 13 for the first cleaning assembly 201 to swing from the retracted position to the extended position (such as Figure 2 and Figure 8 the area with the cleaning assembly 20 within the dotted line away from the middle cleaning assembly 40 as shown). Along the second direction, the convex structure 31 extends to a position close to the edge of the main body 10 or a position close to the edge of the traveling wheel provided at the bottom of the main body 10. The traveling wheel is located on one side of the main body 10 along the second direction and is spaced from the swing area 13. When located at the position close to the edge of the traveling wheel provided at the bottom of the main body 10, that is, the convex structure 31 is located between two adjacent traveling wheels. Thus, when the first cleaning assembly 201 is in the retracted position and the extended position, the first gap 23 between the first cleaning assembly 201 and the main body 10 can be blocked by the convex structure 31, thereby improving the reliability and safety of the first cleaning assembly 201 in the extended and retracted working states.

[0083] The cleaning device in this embodiment further includes a traveling assembly 60. The traveling assembly 60 includes at least one traveling wheel. The at least one traveling wheel is provided at the bottom of the main body 10. Along the traveling direction of the cleaning device, the at least one traveling wheel is located in front of the first cleaning assembly 201 and forms a part of the convex structure 31, and the at least one traveling wheel is at least partially disposed opposite to the first cleaning assembly 201 in the extended position. Thus, after the at least one traveling wheel forms a part of the convex structure 31, when the first cleaning assembly 201 is in the extended position, the at least one traveling wheel can also block the first gap 23 between the first cleaning assembly 201 and the main body 10, which can improve the blocking effect of the convex structure 31 on obstacles, and further improve the reliability and safety of the first cleaning assembly 201 in the extended and retracted working states.

[0084] In the first direction, the distance from the walking wheel to the bottom of the main body 10 in the first region 101 is greater than the maximum distance (i.e., L1) from the convex structure 31 to the bottom of the main body 10 in the first region 101. In the traveling direction of the cleaning device, when the first cleaning assembly 201 is in the expanded position, it respectively has a first projected outer contour, and at least one walking wheel has a second projected outer contour. At least two second projected outer contours correspond one-to-one with at least two first projected outer contours and are respectively located within at least two first projected outer contours. Thus, when the first cleaning assembly 201 expands to the expanded position, the walking wheel can increase the area of the first gap 23 corresponding to the first cleaning assembly 201 that is blocked, thereby further improving the safety of the expanded cleaning assembly 20 and preventing the cleaning assembly 20 from stopping rotating or even falling off.

[0085] The cleaning assembly 20 includes at least one group of second cleaning assemblies 202, and the second cleaning assemblies 202 are held in the retracted position, that is, the second cleaning assemblies 202 are static mops and will not expand to the expanded position mentioned above. Figure 9 The schematic structural diagram of the cleaning device is shown when there are at least two second cleaning assemblies 202.

[0086] Wherein, in the second direction, the convex structure 31 extends around the front side of the second cleaning assembly 202 to a position close to the edge of the main body 10 or the edge of the walking wheel provided close to the bottom of the main body 10. The walking wheel is located on one side of the main body 10 in the second direction. Thus, it can be ensured that each position of the first gap 23 corresponding to the static second cleaning assembly 202 can be blocked by the convex structure 31, improving the safety of the static cleaning assembly 20.

[0087] In the second direction, the second cleaning assembly 202 is located between the opposite sides of the convex structure 31 in the second direction, thereby increasing the range of the first gap 23 at the second cleaning assembly 202 surrounded by the convex structure 31, and thus improving the safety of the second cleaning assembly 202. When the second cleaning assembly 202 includes a tray 21 and a mop 22, at least two arc-shaped side wall segments are formed on the side of the convex structure 31 close to the second cleaning assembly 202 and are arranged around the outer periphery of the tray 21. The arc-shaped side walls block the first gap 23 between the tray 21 and the main body 10, and make the bottom structure of the cleaning device look more compact and beautiful.

[0088] When the cleaning assembly 20 includes at least one set of second cleaning assemblies 202, the cleaning device further includes a traveling assembly 60, which includes at least one traveling wheel. At least one traveling wheel is disposed at the bottom of the main body 10. Along the traveling direction of the cleaning device, at least one traveling wheel is located on the front side of the second cleaning assembly 202 and has a gap from the edge of the convex structure 31 close to the second cleaning assembly 202. Thus, the first gap 23 at the second cleaning assembly 202 can be blocked by both the convex structure 31 and the traveling wheel at the same time, and the overall layout of the bottom of the main body 10 is compact and reasonable.

[0089] In this embodiment, the cleaning assembly 20 can be a combination of an outward expansion type and a static type. In this regard, as Figure 2 and Figure 7 shown, the cleaning assembly 20 can include a first cleaning assembly 201 and a second cleaning assembly 202 at the same time. Both the first cleaning assembly 201 and the second cleaning assembly 202 can include at least one, or can be two or more respectively. Along the second direction, the first cleaning assembly 201 and the second cleaning assembly 202 are respectively located on opposite sides of the main body 10. The first cleaning assembly 201 can move between an inward position and an outward position relative to the main body 10. When the first cleaning assembly 201 is in the outward position, the part located outside the edge contour of the main body 10 has a first volume. When the first cleaning assembly 201 is in the inward position, the part located outside the edge contour of the main body 10 has a second volume. The second cleaning assembly 202 remains stationary relative to the main body 10, and the part of the second cleaning assembly 202 located outside the edge contour of the main body 10 has a third volume. The first volume is greater than the second volume and the third volume. When the first cleaning assembly 201 is in the inward position, it can be entirely located within the edge contour of the main body 10 or partially located within the edge contour and partially located outside the edge contour. The second cleaning assembly 202 can also be entirely located within the edge contour or partially located within the edge contour and partially located outside the edge contour. In this regard, this embodiment does not make a unique limitation.

[0090] When the second cleaning assembly 202 also includes a tray 21 and a mop 22, an arc-shaped side wall surrounding the outer periphery of the tray 21 is formed on the side wall surface of the convex structure 31 close to the second cleaning assembly 202. The arc-shaped side wall shields the first gap 23, improving the safety of the second cleaning assembly 202, preventing the second cleaning assembly 202 from stopping or falling, and making the bottom structure of the cleaning device look more compact and beautiful. On the side of the convex structure 31 close to the first cleaning assembly 201, it is a relatively gentle structure extending towards the edge of the main body 10 away from the second cleaning assembly 202. The side wall of the convex structure 31 corresponding to the first cleaning assembly 201 may include at least two arc-shaped side walls, and the radian of at least two arc-shaped side walls may be smaller than the radian of the arc-shaped side wall close to the second cleaning assembly 202. Finally, the convex structure 31 fully shields the area of the first gap 23 located between the first cleaning assembly 201 and the second cleaning assembly 202.

[0091] Along the second direction, the convex structure 31 includes a first end 3102 close to the first cleaning assembly 201 and a second end 3103 close to the second cleaning assembly 202. Along the traveling direction of the cleaning device, the second end 3103 is located behind the first end 3102. Thus, not only can the convex structure 31 shield the area of the first gap 23 located between the first cleaning assembly 201 and the second cleaning assembly 202, but it also does not interfere with the outward expansion operation of the first cleaning assembly 201.

[0092] The traveling assembly 60 may specifically include a first traveling wheel 61 and a second traveling wheel 62. The first traveling wheel 61 is installed at the bottom of the main body 10. The second traveling wheel 62 is installed at the bottom of the main body 10 and is spaced from the first traveling wheel 61 along the second direction. Along the traveling direction of the cleaning device, both the first traveling wheel 61 and the second traveling wheel 62 are located in front of the cleaning assembly, and there is an installation distance between the second traveling wheel 62 and the edge of the convex structure 31 close to the cleaning assembly. Among them, along the first direction, the wheel heights of the first traveling wheel 61 and the second traveling wheel 62 from the bottom of the main body 10 to the first area 101 are the same, and the wheel height is greater than the maximum distance (L1) from the bottom of the convex structure 31 away from the main body 10 to the first area 101. Along the traveling direction of the cleaning device, when the first cleaning assembly 201 is in the outward expansion position, it has a first projected outer contour, and the first traveling wheel 61 has a second projected outer contour, and the second projected outer contour is located within the first projected outer contour. Thus, when the first cleaning assembly 201 is in the outward expansion position, in addition to the extended part of the convex structure 31 shielding the first gap 23 between the first cleaning assembly 201 and the main body 10, the first traveling wheel 61 can also shield the first gap 23, thereby further improving the safety of the first cleaning assembly 201 in the outward expansion position.

[0093] For the installation of the traveling assembly 60, a first opening 14 and a second opening 15 are further provided at the bottom of the main body 10. Along the second direction, the first opening 14 and the second opening 15 are respectively located on opposite sides of the main body 10. Along the traveling direction of the cleaning device, the first opening 14 extends from the side of the convex structure 31 away from the first cleaning assembly 201 towards the side close to the first cleaning assembly 201 and penetrates the side wall of the convex structure 31 close to the first cleaning assembly 201. Along the traveling direction of the cleaning device, there is an installation spacing between the second opening 15 and the side wall surface of the convex structure 31 close to the second cleaning assembly 202. The first traveling wheel 61 is installed in the first opening 14, and the second traveling wheel 62 is installed in the second opening 15. The settings of the first opening 14 and the second opening 15 can not only ensure that the traveling assembly 60 can drive the cleaning device to travel, but also enable the corresponding traveling wheels to block the first gap 23, thereby improving the safety of each cleaning assembly. Moreover, the layout among the first opening 14, the convex structure 31 and the first cleaning assembly 201 is more compact, saving the installation space at the bottom of the main body 10.

[0094] In addition, along the second direction, the middle sweeping assembly is installed between the first opening 14 and the second opening 15 (or between the first traveling wheel 61 and the second traveling wheel 62), so that the layout at the bottom of the main body 10 is more compact and the space utilization rate is higher.

[0095] In some embodiments, when the traveling assembly 60 includes at least two traveling wheels, the at least two traveling wheels are spaced along the second direction, and the maximum distance from at least a part of the convex structure 31 between two adjacent traveling wheels away from the bottom of the main body 10 to the first area 101 is greater than or equal to H. Thus, during the traveling of the cleaning device, most of the obstacles can be blocked by the higher part of the convex structure 31 between two adjacent traveling wheels.

[0096] In some embodiments, along the traveling direction of the cleaning device, the side wall surface of the convex structure 31 close to the cleaning assembly 20 includes a straight line segment 3104, and the straight line segment 3104 extends along the second direction. The side wall surface of the straight line segment 3104 structure is convenient to process and has a low difficulty.

[0097] In some embodiments, along the traveling direction of the cleaning device, the side wall surface of the convex structure 31 close to the cleaning assembly 20 includes a straight line segment 3104 and at least two arc segments 3105, and the arc segments 3105 form a concave arc structure towards the side away from the cleaning assembly. As Figure 7As shown, at least two arc segments 3105 are respectively located at opposite ends of the straight segment 3104. Along the traveling direction of the cleaning device, the arc segments 3105 are arranged around the outer periphery of the front side of the cleaning assembly 20. The arc lengths of the at least two arc segments 3105 may be the same or different. The arc segments 3105 fit better with the contour structure of the front side of the cleaning assembly 20, thereby increasing the shielding area of the first gap 23.

[0098] In some embodiments, along the traveling direction of the cleaning device, the side wall surface of the convex structure 31 on the side close to the cleaning assembly 20 includes at least two adjacent arc segments 3105. Along the traveling direction of the cleaning device, the at least two arc segments 3105 are arranged around the outer periphery of the front side of the cleaning assembly 20. Similarly, the arc segments 3105 fit better with the contour structure of the front side of the cleaning assembly 20, thereby increasing the shielding area of the first gap 23.

[0099] In some embodiments, when the cleaning device further includes a traveling assembly 60, the traveling assembly 60 is disposed at the bottom of the main body 10 and in front of the cleaning assembly 20. The traveling assembly 60 includes at least one traveling wheel. Along the traveling direction of the cleaning device, the convex structure 31 includes a side wall surface on the side close to the cleaning assembly 20, and the outer wall surface of at least one traveling wheel on the side close to the cleaning assembly 20 constitutes a part of the side wall surface. Thus, by means of the height of the traveling wheel, the overall height of the convex structure 31 is increased, the blocking rate for obstacles is improved, and the arrangement among the traveling assembly 60, the convex structure 31, and the cleaning assembly 20 is made more compact, improving the space utilization rate of the limited space at the bottom of the main body 10.

[0100] In some embodiments, when the cleaning assembly 20 includes at least two groups, the part of the side wall surface located between the adjacent two groups of cleaning assemblies 20 is a convex arc segment 1111, and the convex arc segment 1111 protrudes in the direction close to the cleaning assembly. The convex arc segment 1111 may be the wall surface of the extension part 111 on the side close to the cleaning assembly 20 mentioned above, or may be an arc segment of the diameter of the two arc segments 3105. The convex arc segment 1111 improves the overall aesthetics of the main body 10 and can shield the gap between the adjacent two groups of cleaning assemblies 20. Along the second direction, at least one side of the side wall surface of the convex structure 31 on the opposite sides of the traveling wheel is a combination of one or more of the arc segment 3105 and the straight segment 3104 (such as Figure 7 being two arc segments 3105, and there is a gap between the arc segment 3105 and the straight segment 3104 and the traveling wheel, thereby preventing interference with the movement of the traveling wheel. For example, there are arc segments 3105 or straight segments 3104 on both sides of the traveling wheel, or there may be only arc segments 3105 or straight segments 3104 on one side. When the traveling wheel includes at least two, the arc segment 3105 and / or the straight segment 3104 may be only located in the area between the adjacent two traveling wheels, that is to say, the convex structure 31 may be only located between the adjacent two traveling wheels.

[0101] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0102] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of this application.

[0103] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
