Description

Technical Field

[0002] Currently, cleaning robots include robotic vacuum cleaners, floor mops (robots with mopping functions but no sweeping function), dual-disc robotic vacuum cleaners, and floor scrubbers. Some cleaning robots have a mop at the bottom, allowing them to perform wet cleaning by contacting the mop with the surface to be cleaned (such as the floor or tabletop) in mopping mode. However, during the cleaning robot's operation and / or while the mop is being raised and lowered, obstacles on the surface can cause the mop to malfunction or even stop working if it comes into contact with them. This not only affects the robot's efficiency but also reduces the user experience. Utility Model Content

[0032] The subject includes:

[0033] Top shell;

[0034] A bottom shell is disposed at the bottom of the top shell. A first groove is provided on the side of the bottom shell near the top shell.

[0035] Furthermore, it also includes:

The cleaning component is installed at the bottom of the main body and can clean the surface to be cleaned under the drive and control of the cleaning device. A first gap exists between the surface of the main body near the cleaning component and the cleaning component. This first gap is to ensure that the cleaning component can adhere tightly to the surface to be cleaned during the cleaning process. The shielding member is located in front of the cleaning component and can block the first gap. Therefore, since the first gap is blocked by the shielding member, obstacles (especially obstacles that can pass through the first gap) are less likely to enter the first gap and scratch or jam the cleaning component, avoiding malfunctions or even detachment of the cleaning component due to scratching or jamming by obstacles. Therefore, by using the shielding member to block the first gap between the cleaning component and the main body, this application can improve the stability and reliability of the cleaning component during operation, thereby ensuring the working efficiency of the cleaning robot and providing a better user experience.

[0056] The cleaning component 20 of the cleaning equipment includes a rotating mop 22. To facilitate disassembly, replacement, or maintenance of the mop 22, it is connected to the drive mechanism 50 installed in the cleaning equipment via magnetic attraction or other detachable means. To ensure the mop 22 better conforms to the surface to be cleaned for improved cleaning efficiency, a certain gap is typically maintained between the mop 22 and the bottom surface of the cleaning equipment when cleaning the surface. In some cleaning equipment products, this gap may remain between the mop 22 and the cleaning equipment. In other cleaning equipment products, the drive mechanism 50 is a mechanism that can drive the mop 22 to rise and fall. In this case, when the cleaning equipment starts the cleaning mode, it controls the drive mechanism 50 to first lower the mop 22 to a cleaning position close to the surface to be cleaned, and after cleaning, it controls the drive mechanism 50 to raise the mop 22 to a position away from the surface to be cleaned. In this case, when the mop 22 is in the cleaning position, there will be a larger gap between it and the bottom surface of the cleaning equipment. Regardless of the type of cleaning equipment mentioned above, the gap between the mop 22 and the bottom surface of the cleaning equipment, or the gap that exists when the mop 22 descends from the ground to the cleaning position, can cause some low obstacles (such as electronic scales, flat household items) or obstacles within the preset height range to easily scrape against the mop 22 along the gap. This can cause the mop 22 to get stuck by the obstacles, resulting in a decrease in rotation speed or direct stoppage, or even the risk of it being disassembled and detached from the cleaning equipment. This risk is particularly high when the mop 22 is connected to the drive mechanism 50 by magnetic attraction.

[0057] To address the above problems, this embodiment provides a cleaning device. Please refer to [link / reference]. Figures 1 to 6The cleaning device includes a main body 10, a cleaning component 20, and a shielding member 30. The main body 10 has an installation space for installing and supporting other components of the cleaning device. Along a first direction, the cleaning component 20 is installed at the bottom of the main body 10, and a first gap 23 exists between the surface of the main body 10 near the cleaning component 20 and the cleaning component 20. The first direction is the height direction of the main body 10. Figure 1 The direction indicated by the middle arrow X. The blocking member 30 is located on the side of the main body 10 near the cleaning component 20, along the traveling direction of the cleaning device. The blocking member 30 is positioned in front of the cleaning component 20 and is used to block the first gap 23. Therefore, the blocking member 30 can prevent obstacles from entering the first gap 23 and scraping the cleaning component 20, avoiding the cleaning component 20 being stuck or detached from the cleaning device. For example, during the movement of the cleaning device with the cleaning component 20, or during the process of the cleaning component 20 rising to a position off the ground or descending to the cleaning position under the drive mechanism 50, the blocking member 30 can block obstacles, preventing the cleaning component 20 from being scraped by obstacles.

[0058] In this embodiment, the cleaning device includes a main body 10, a cleaning component 20, and a shielding member 30. The main body 10 provides installation space and protective support for other components of the cleaning device. The cleaning component 20 is installed at the bottom of the main body 10 and can clean the surface to be cleaned under the drive and control of the cleaning device. A first gap 23 exists between the surface of the main body 10 near the cleaning component 20 and the cleaning component 20. This first gap 23 is to ensure that the cleaning component 20 can adhere tightly to the surface to be cleaned during the cleaning process. The shielding member 30 is disposed on the side of the main body 10 near the cleaning component 20 and can shield the first gap 23. Therefore, since the first gap 23 is shielded by the shielding member 30, obstacles (especially obstacles whose shape can penetrate the first gap 23) are less likely to enter the first gap 23 and scratch or jam the cleaning component 20, thus preventing the cleaning component 20 from malfunctioning or even detaching from the cleaning device due to scratching or jamming by obstacles. Therefore, by using the shielding member 30 to shield the first gap 23 between the cleaning component 20 and the main body 10, this application can improve the stability and reliability of the cleaning component 20 during operation, thereby ensuring the working efficiency of the cleaning robot and providing a better user experience.

[0059] The cleaning equipment in this embodiment may include a sweeping robot, a floor scrubbing robot (a robot with mopping function but no sweeping function), a dual-disc sweeping robot, a floor scrubbing robot, etc.

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

[0061] like Figures 1 to 3 As shown, the surface of the main body 10 near the cleaning component 20 includes a first region 101, within which the cleaning component 20 is located. Along a first direction, the distance from the first region 101 to the side of the cleaning component 20 near the main body 10 is the height H of a first gap. The shielding member 30 includes a protruding structure 31. Along the travel direction of the cleaning device, the protruding structure 31 protrudes from the front of the first region 101, and a first gap exists between the protruding structure 31 and the cleaning component 20, thereby avoiding interference with the movement of the cleaning component 20. The travel direction of the cleaning device is... Figure 1 The direction indicated by the middle arrow Y. Along the first direction, the maximum distance from at least part of the protruding structure 31 away from the bottom of the main body 10 to the first region 101 is greater than or equal to H. That is, only a portion of the protruding structure 31 may have a maximum distance greater than H from the first region 101, or all portions may have a maximum distance greater than H. It should be noted that when the cleaning device is placed on the surface to be cleaned, the bottom of the protruding structure 31 away from the main body 10 specifically refers to the lowest point of the protruding structure 31 away from the main body 10. The maximum distance from the side of the protruding structure 31 away from the main body 10 to the first region 101 is the maximum protrusion height of the protruding structure 31 protruding from the surface of the first region 101. Thus, in this embodiment, the first gap 23 is blocked by making the maximum protrusion height of the protruding structure 31 greater than or equal to the height H of the first gap 23 along the first direction. Whether the protruding structure 31 is installed on the main body 10 or integrally formed with the main body 10, assembly is efficient and convenient. The protruding structure 31 protrudes from one side of the first region 101, which can not only block obstacles, but also does not increase the structural complexity of the cleaning equipment.

[0062] like Figure 5 As shown, the cleaning assembly 20 includes a tray 21 and a mop 22. The tray 21 is mounted in the first region 101, and the mop 22 is disposed on the surface of the tray 21 away from the main body 10. When the cleaning device also includes a drive mechanism 50, the drive mechanism 50 is mounted inside the main body 10 and connected to the tray 21. The drive mechanism 50 may include a drive member 51 and a transmission assembly 52. ​​The transmission assembly 52 is connected to the drive member 51 and extends at least partially outside the main body 10 and is connected to the tray 21. The tray 21 can then rotate the mop 22 under the drive of the drive 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. Because the cleaning device is equipped with a shielding component, obstacles are less likely to enter the first gap 23 and scrape the cleaning component 20 off. The tray 21 of the cleaning component 20 and the transmission component 52 can be detachably connected via a magnetic connection or other snap-fit ​​structure.

[0064] Along the travel direction of the cleaning equipment, a transition surface 3100 is provided on the front side of the protruding structure 31 away from the cleaning component 20. Along the first direction, a third distance exists between the transition surface 3100 and the first region 101, and this third distance gradually decreases in the direction away from the cleaning component 20. Thus, the transition surface 3100 forms an inclined surface that slopes away from the cleaning component 20, meaning the horizontal plane of the transition surface 3100 gradually rises in the direction away from the cleaning component 20, creating a smooth transition surface structure on the side of the protruding structure 31 away from the cleaning component 20. Therefore, during the movement of the cleaning equipment, the transition surface 3100 can buffer the collision between the protruding structure 31 and obstacles, dispersing the impact force exerted on the protruding structure 31 by the obstacle, thereby improving the service life of the protruding structure 31. Along the first direction, the projected outer contour of the transition surface 3100 can be arc-shaped, rectangular, or other irregular shapes; this embodiment does not impose a unique limitation on this.

[0065] Secondly, to improve the structural strength of the raised structure 31, this embodiment may also provide a connecting surface 3101 between the transition surface 3100 and the edge of the raised structure 31 near the cleaning component 20. This connecting surface 3101 connects the transition surface 3100 and the side of the raised structure 31 near the cleaning component 20. Along the traveling direction of the cleaning device, the connecting surface 3101 provides a certain thickness between the transition surface 3100 and the edge of the raised structure 31 near the cleaning component 20, thereby improving the overall structural strength of the raised structure 31. The connecting surface 3101 can be one of a convex arc surface, a plane, or a concave surface, or a surface structure composed of at least one of these three and at least one other. This embodiment does not impose a unique limitation on this. Furthermore, a smooth, rounded corner surface may also be provided between the connecting surface 3101 and the transition surface 3100, thereby improving the roundness of the overall shape of the raised structure 31 and preventing scratches on furniture or other objects.

[0066] In some embodiments, when the raised portion 312 mentioned below is provided on the raised structure 31, the transition surface 3100 may be provided on the side of the raised structure 31 and / or the raised portion 312 away from the cleaning component 20 along the traveling direction of the cleaning device, thereby reducing the force generated by the direct collision between the raised 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 gap between the protruding structure 31 and the tray 21, so that the protrusion 311 will not interfere with the rotation of the tray 21 during the rotation operation of the tray 21.

[0068] Along the first direction, a raised portion 312 protrudes from the surface of the protruding structure 31 away from the main body 10. The raised portion 312 is located on the side of the protruding structure 31 near the cleaning component 20, specifically near the edge of the protruding structure 31 near the tray 21. The maximum distance from the bottom of the protruding structure 31 away from the main body 10 to the first region 101 is the distance from the end of the raised portion 312 away from the main body 10 to the first region 101. The protruding structure 31 and its raised portion 312 are both along the second direction (e.g., ...). Figure 1 Extending in the direction indicated by the middle arrow Z, the protruding structure 31 has a second distance between its two ends and the raised portion 312 along the second direction. In other words, this embodiment primarily uses the protruding structure 31 and the raised portion 312 to block obstacles. The protruding structure 31 raises the raised portion 312 to a higher height than the first region 101, enabling the raised portion 312 to block obstacles of more types and sizes. Simultaneously, because the protruding structure 31 has a second distance between its two ends and the raised portion 312, the area of ​​the protruding structure 31 offset from the raised portion 312 along the second direction is closer to the first region 101 than the raised portion 312. Therefore, during the movement of the cleaning equipment and cleaning components 20, while the raised portion 312 blocks obstacles, the area of ​​the protruding structure 31 offset from the raised portion 312 reduces the difficulty of the cleaning equipment overcoming obstacles and improves the smoothness of the cleaning equipment's movement. The raised portion 312 can be attached to the raised structure 31 by means of snap-fit, welding or other connection methods. The raised portion 312 can also be integrally formed on the surface of the raised structure 31, thereby reducing the assembly steps of the main body 10 and improving the assembly efficiency of the cleaning equipment.

[0069] The raised structure 31 specifically includes at least one of the following structural forms: boss 311, bump, bulge, etc., and the projection of the raised structure 31 near the edge of the cleaning component 20 along the first direction can be an arc shape that matches the outer periphery shape of the tray 21.

[0070] In other embodiments, such as when the wheels of the cleaning device are large enough to make the distance between the main body 10 and the surface to be cleaned higher, the height of the raised portion 312 can be increased.

[0071] The cleaning components 20 include at least two sets; if there are two sets, the cleaning device is a dual-rotary cleaning structure, thereby improving the cleaning efficiency and effectiveness of the surface to be cleaned through at least two sets of cleaning components 20. Figures 1 to 2 As shown, at least two sets of cleaning components 20 are arranged along the second direction, and at least two protruding structures 31 are integrally formed and respectively corresponding to the at least two sets of cleaning components 20. Thus, the protruding structures 31 shield the first gap 23 between the at least two sets of cleaning components 20 and the main body 10, improving the reliability of the at least two sets of cleaning components 20.

[0072] In some embodiments, the raised portion 312 on the raised structure 31 may include at least two, with each of the at least two raised portions 312 corresponding to at least two sets of cleaning components 20, so that the at least two sets of cleaning components 20 are less likely to be scratched by obstacles. Along the traveling direction of the cleaning device, the portion of the raised structure 31 located between two adjacent raised portions 312 extends toward the minimum gap between the two adjacent sets of cleaning components 20. That is, along the traveling direction of the cleaning device, the portion of the raised structure 31 located between two adjacent raised portions 312 forms a rearwardly extending extension 111, which can block the first gap 23 between the two adjacent sets of cleaning components 20 and the main body 10, and make the arrangement of the raised structure 31 and the at least two sets of cleaning components 20 at the bottom of the main body 10 more compact and aesthetically pleasing. Secondly, along the first direction, the distance from the end of the extension 111 away from the main body 10 to the first region 101 is also smaller than the distance from the end of the raised portion 312 away from the main body 10 to the first region 101, thereby reducing the difficulty for the cleaning device to overcome obstacles in that region. In some embodiments, the raised structure 31 does not have an extension 111 between adjacent sets of cleaning components 20, such as... Figure 7 As shown, the middle region of the protruding structure 31 (such as the region between the first cleaning component 201 and the second cleaning component 202) has a straight sidewall structure on the side near the cleaning component 20.

[0073] When there is a first gap 23 between the cleaning component 20 and the main body 10, the cleaning component 20 can closely adhere to the surface to be cleaned. To prevent the protruding structure 31 and / or its raised portion 312 from being too high and causing friction with the surface to be cleaned, the distance from the end of the cleaning component 20 away from the main body 10 to the first region 101 along the first direction is greater than the maximum distance from the end of the protruding structure 31 away from the first region 101 to the first region 101. Therefore, during the cleaning process of the cleaning component 20, the protruding structure 31 will not contact the surface to be cleaned, nor will it rub against it. This avoids the protruding structure 31 and / or its raised portion 312 from scratching the surface to be cleaned and / or itself, as well as generating friction noise, thus improving the service life of the protruding structure 31.

[0074] When the mop 22 is relatively thick, in this embodiment, the raised structure 31 can be positioned away from the bottom apex of the main body 10 (such as the top position of the raised portion 312 away from the main body 10) not exceeding the thickness area of ​​the mop 22 when it is in contact with the surface to be cleaned. However, since the mop 22 is easily worn thinner after prolonged use, the raised structure 31 may come into contact with the surface to be cleaned after the mop 22 becomes thinner (if it has a raised portion 312, the raised portion 312 is likely to come into contact with the surface to be cleaned). Therefore, to further ensure that the raised structure 31 does not scratch the surface to be cleaned, such as... Figure 4As shown, along the first direction, the maximum distance from the end of the protruding structure 31 furthest from the main body 10 (i.e., the apex of the bottom end of the protruding structure 31) to the first region 101 is L1, and the distance from the surface of the tray 21 furthest 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 protruding structure 31 will not come into contact with the surface to be cleaned. Even if the mop 22 becomes thinner due to long-term use, the protruding structure 31 will not scrape the surface to be cleaned. Preferably, L1 is less than L2, thereby further reducing the risk of the protruding structure 31 coming into contact with the surface to be cleaned.

[0075] Secondly, along the first direction, the distance from the surface of the cleaning component 20 near the body 10 to the first region 101 is the height H of the first gap 23. When the cleaning component 20 includes the tray 21, H is specifically the distance from the surface of the tray 21 near the body 10 to the first region 101. H is less than L1 so that the protruding structure 31 can completely cover 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 (e.g., Figure 2 The included angle α shown satisfies the relationship: 49°≤α≤79°. The central angle is the angle formed by the radii of the two opposite ends of the raised portion 312 along its own arc length direction. This embodiment sets the arc length of the raised portion 312 within a reasonable range by ensuring that the central angle of the raised portion 312 is within the aforementioned range. This prevents the arc length of the raised portion 312 from being too short, thus reducing its obstruction rate against obstacles, or from being too long, thus increasing the difficulty for the cleaning equipment to overcome obstacles. In other words, when the central angle is within the aforementioned range, the raised portion 312 has a high obstruction rate against obstacles, allowing the cleaning equipment to overcome obstacles more effectively. The size of the central angle can specifically include one of the following: 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°, or any other angle value between 49° and 79°. In this case, the portion of the sidewall of the boss 311 near the tray 21 relative to the raised portion 312, as well as the portion between two adjacent raised portions 312, are all arc-shaped structures. Furthermore, the edge of the raised portion 312 near the tray 21 is on the same plane as the sidewall, making the overall structure of the shielding member 30 neater and more aesthetically pleasing.

[0077] The cleaning device in this embodiment also includes a central sweeping component 40. Along the first direction, the central sweeping component 40 is installed at the bottom of the main body 10. Along the traveling direction of the cleaning device, the central sweeping component 40 is located on the side of the protruding structure 31 away from the cleaning component 20. Therefore, during the movement of the cleaning device, the surface to be cleaned is first cleaned by the central sweeping component 40, thereby reducing the cleaning pressure on the surface to be cleaned by the cleaning component 20. It also prevents some debris from accumulating in the area between the protruding structure 31 and the cleaning component 20, and makes the arrangement at the bottom of the cleaning device more compact, resulting in high space utilization. The central 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. The roller brush is also connected to a drive component installed inside the main body 10 to rotate and sweep debris under the drive of the drive component. The cleaning device collects the swept debris into the dust box installed inside the main body 10.

[0078] like Figure 6 As shown, the main body 10 in this embodiment includes a top shell 11 and a bottom shell 12. Along a first direction, the bottom shell 12 covers the bottom of the top shell 11. The top shell 11 and the bottom shell 12 can enclose a mounting cavity for installing other components of the cleaning equipment (such as dust boxes, water boxes, control boards, electrical components, etc.). A first groove 121 is provided on the side of the bottom shell 12 near the top shell 11. The first groove 121 is recessed away from the top shell 11 to form a protruding structure 31 on the surface of the bottom shell 12 away from the top shell 11. Therefore, this embodiment, while forming the protruding structure 31 through the first groove 121, also increases the size of the mounting cavity, thereby providing sufficient space for the installation of other components and improving the space utilization rate of the cleaning equipment. The first groove 121 and the protruding structure 31 can be obtained by punching on the bottom shell 12, saving processing materials for the bottom shell 12 and making processing efficient and convenient.

[0079] The cleaning device in this embodiment also includes a drive mechanism 50, which is installed inside the main body 10 and connected to the cleaning component 20. The drive mechanism 50 is 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-free position mentioned above in this embodiment, and the second position is the cleaning position mentioned above. When the cleaning component 20 is in 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 in 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 region 101 is less than the maximum distance from the protruding structure 31 to the first region 101. Thus, when the cleaning component 20 is not needed for mopping, it can be housed in the groove formed by the protruding structure 31 (the first region 101 is the bottom surface of the groove), thereby protecting 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 in the first position, this gap will be blocked by the blocking member 30, thus preventing the cleaning component 20 from being scraped off by obstacles when it is in the first position. When the cleaning component 20 is in any raised position between the second position and the first position, since the blocking member 30 can block the first gap 23 when it is in the second position, the raised position will also be blocked by the blocking member 30. Therefore, the cleaning component 20 will not be scraped or stuck by obstacles during the raising or lowering process.

[0080] The drive mechanism 50 includes a drive member 51 and a transmission assembly 52 to drive the cleaning assembly 20 to rotate. In order to achieve the lifting and lowering of the cleaning assembly 20, the transmission assembly 52 may include a first abutment and a second abutment. The first abutment is connected to the drive member 51 and the second abutment, and the second abutment is connected to the cleaning assembly 20. The second abutment has a track surface. The first abutment can move and abut against the track surface. The drive member 51 is configured to drive the first abutment to rotate so that the first abutment moves on the track surface, thereby lifting and lowering the cleaning assembly 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. There may also be at least two sets of first cleaning components 201, and these at least two sets of first cleaning components 201 may be arranged along a second direction. Figure 8As shown, the first cleaning component 201 can move relative to the main body 10 between an inward position and an outward position. If there are two sets, the cleaning device is a device with a double-rotor structure and an outward edge cleaning function. When the first cleaning component 201 is in the outward position, the portion outside the edge contour of the main body 10 has a first volume, and when the first cleaning component 201 is in the inward position, the portion outside the edge contour of the main body 10 has a second volume, and the first volume is larger than the second volume. When the first cleaning component 201 is in the inward position, it can 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, or at least partially located outside the edge contour of the main body 10. This embodiment does not impose a unique limitation on this.

[0082] Along the second direction, the main body 10 has a swing area 13 for the first cleaning component 201 to swing from an inward position to an outward position (e.g., ...). Figure 2 and Figure 8 The dotted line shown is the area containing the cleaning component 20 within the sweeping component 40. Along the second direction, the protruding structure 31 extends to a position near the edge of the main body 10 or near the edge of the traveling wheel located 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 apart from the swing area 13. When located near the edge of the traveling wheel located at the bottom of the main body 10, the protruding structure 31 is located between two adjacent traveling wheels. Therefore, when the first cleaning component 201 is in the retracted position and the expanded position, the first gap 23 between the first cleaning component 201 and the main body 10 can be blocked by the protruding structure 31, thereby improving the reliability and safety of the first cleaning component 201 in both the expanded and retracted working states.

[0083] The cleaning device in this embodiment also includes a walking component 60, which includes at least one walking wheel. The at least one walking wheel is disposed at the bottom of the main body 10 and along the traveling direction of the cleaning device. The at least one walking wheel is located in front of the first cleaning component 201 and forms part of the protruding structure 31. The at least one walking wheel is at least partially disposed opposite to the first cleaning component 201 in the outward expansion position. Thus, after the at least one walking wheel forms part of the protruding structure 31, when the first cleaning component 201 is in the outward expansion position, the at least one walking wheel can also block the first gap 23 between the first cleaning component 201 and the main body 10, thereby improving the blocking effect of the protruding structure 31 on obstacles, and thus improving the reliability and safety of the first cleaning component 201 in the outward expansion and inward contraction working state.

[0084] Along the first direction, the distance from the bottom of the main body 10 to the first region 101 of the traveling wheel is greater than the maximum distance (i.e., L1) from the bottom of the protruding structure 31 to the first region 101 of the main body 10. Along the travel direction of the cleaning device, when the first cleaning component 201 is in the extended position, it has a first projected outer contour, and at least one traveling 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. Therefore, when the first cleaning component 201 extends to the extended position, the traveling wheel can increase the area of ​​the first gap 23 corresponding to the first cleaning component 201 that is blocked, thereby further improving the safety of the extended cleaning component 20 and preventing the cleaning component 20 from stopping or even falling off.

[0085] The cleaning component 20 includes at least one set of second cleaning components 202, which are kept in the retracted position, that is, the second cleaning component 202 is a static mop and will not extend outward to the extended position mentioned above. Figure 9 A schematic diagram of the cleaning device is shown when the second cleaning component 202 has at least two components.

[0086] In this configuration, along the second direction, the protruding structure 31 extends around the front side of the second cleaning component 202 to a position near the edge of the main body 10 or near the edge of the traveling wheel located at the bottom of the main body 10, with the traveling wheel located on one side of the main body 10 along the second direction. This ensures that all positions of the first gap 23 corresponding to the static second cleaning component 202 are covered by the protruding structure 31, improving the safety of the static cleaning component 20.

[0087] Along the second direction, the second cleaning component 202 is located between the two opposite sides of the protruding structure 31 along the second direction, thereby increasing the area surrounded by the protruding structure 31 at the first gap 23 at the second cleaning component 202, thus improving the safety of the second cleaning component 202. When the second cleaning component 202 includes a tray 21 and a mop 22, the side of the protruding structure 31 near the second cleaning component 202 forms at least two arc-shaped sidewall segments surrounding the outer periphery of the tray 21. The arc-shaped sidewalls cover 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 aesthetically pleasing.

[0088] When the cleaning component 20 includes at least one set of second cleaning components 202, the cleaning device also includes a walking component 60, which includes at least one walking wheel. At least one walking wheel is located at the bottom of the main body 10, along the traveling direction of the cleaning device, and is positioned in front of the second cleaning component 202 with a gap between it and the edge of the protruding structure 31 near the second cleaning component 202. Thus, the first gap 23 at the second cleaning component 202 can be simultaneously covered by the protruding structure 31 and the walking wheel, resulting in a compact and reasonable overall layout at the bottom of the main body 10.

[0089] In this embodiment, the cleaning component 20 can be a combination of an externally expandable type and a static type. For example... Figure 2 and Figure 7 As shown, the cleaning component 20 may simultaneously include a first cleaning component 201 and a second cleaning component 202. Each of the first cleaning component 201 and the second cleaning component 202 may include at least one, or two or more, respectively. Along the second direction, the first cleaning component 201 and the second cleaning component 202 are located on opposite sides of the main body 10. The first cleaning component 201 can move relative to the main body 10 between an inward position and an outward position. When in the outward position, the portion of the first cleaning component 201 located outside the edge contour of the main body 10 has a first volume. When in the inward position, the portion of the first cleaning component 201 located outside the edge contour of the main body 10 has a second volume. The second cleaning component 202 remains stationary relative to the main body 10. The portion of the second cleaning component 202 located outside the edge contour of the main body 10 has a third volume. The first volume is larger than both the second and third volumes. When the first cleaning component 201 is in the retracted 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. Similarly, the second cleaning component 202 can also be entirely located within the edge contour or partially located within the edge contour and partially located outside the edge contour. This embodiment does not impose any unique limitations on either of these aspects.

[0090] When the second cleaning component 202 also includes a tray 21 and a mop 22, the side wall of the protruding structure 31 near the second cleaning component 202 forms an arc-shaped sidewall surrounding the outer periphery of the tray 21. The arc-shaped sidewall covers the first gap 23, improving the safety of the second cleaning component 202, preventing it from stopping or falling, and making the bottom structure of the cleaning device look more compact and aesthetically pleasing. The side of the protruding structure 31 near the first cleaning component 201 is a relatively gentle structure extending towards the edge of the main body 10 in a direction away from the second cleaning component 202. The side wall of the protruding structure 31 corresponding to the first cleaning component 201 may include at least two arc-shaped sidewalls, and the curvature of the at least two arc-shaped sidewalls may be smaller than the curvature of the arc-shaped sidewall near the second cleaning component 202. Ultimately, the protruding structure 31 fully covers the area of ​​the first gap 23 located between the first cleaning component 201 and the second cleaning component 202.

[0091] Along the second direction, the protruding structure 31 includes a first end 3102 near the first cleaning component 201 and a second end 3103 near the second cleaning component 202. Along the travel direction of the cleaning device, the second end 3103 is located behind the first end 3102. Therefore, the protruding structure 31 not only shields the area of ​​the first gap 23 located between the first cleaning component 201 and the second cleaning component 202, but also does not interfere with the outward expansion operation of the first cleaning component 201.

[0092] The walking component 60 may specifically include a first walking wheel 61 and a second walking wheel 62. The first walking wheel 61 is mounted on the bottom of the main body 10. The second walking wheel 62 is mounted on the bottom of the main body 10 and is spaced apart from the first walking wheel 61 along a second direction. Along the traveling direction of the cleaning device, both the first walking wheel 61 and the second walking wheel 62 are located on the front side of the cleaning component, and the second walking wheel 62 has an installation gap with the edge of the protruding structure 31 near the cleaning component. Along the first direction, the wheel heights of the first walking wheel 61 and the second walking wheel 62 from the bottom of the main body 10 to the first region 101 are the same, and the wheel height is greater than the maximum distance (L1) from the bottom of the protruding structure 31 to the first region 101. Along the traveling direction of the cleaning device, when the first cleaning component 201 is in the outward-expanding position, it has a first projected outer contour, and the first walking wheel 61 has a second projected outer contour, which is located within the first projected outer contour. Therefore, when the first cleaning component 201 is in the outward position, in addition to the extension of the protruding structure 31 blocking the first gap 23 between the first cleaning component 201 and the main body 10, the first traveling wheel 61 can also block the first gap 23, thereby further improving the safety of the first cleaning component 201 in the outward position.

[0093] To accommodate the walking component 60, the bottom of the main body 10 is provided with a first opening 14 and a second opening 15, located on opposite sides of the main body 10 along a second direction. Along the direction of travel of the cleaning device, the first opening 14 extends from the side of the protruding structure 31 away from the first cleaning component 201 towards the side closer to the first cleaning component 201, and penetrates the side wall of the protruding structure 31 near the first cleaning component 201. Along the direction of travel of the cleaning device, there is an installation gap between the second opening 15 and the side wall of the protruding structure 31 near the second cleaning component 202. The first walking wheel 61 is installed within the first opening 14, and the second walking wheel 62 is installed within the second opening 15. The arrangement of the first opening 14 and the second opening 15 not only ensures that the walking component 60 can drive the cleaning device forward, but also allows the corresponding walking wheels to shield the first gap 23, thereby improving the safety of each cleaning component. Furthermore, the layout of the first opening 14, the protruding structure 31, and the first cleaning component 201 is more compact, saving installation space at the bottom of the main body 10.

[0094] In addition, along the second direction, the central scanning component 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) to make the layout at the bottom of the main body 10 more compact and the space utilization rate higher.

[0095] In some embodiments, when the walking assembly 60 includes at least two walking wheels, the at least two walking wheels are spaced apart along a second direction, and the maximum distance from the bottom of the main body 10 to the first region 101 of the protruding structure 31 located between two adjacent walking wheels is greater than or equal to H. Thus, during the movement of the cleaning equipment, most obstacles can be blocked by the higher portion of the protruding structure 31 located between two adjacent walking wheels.

[0096] In some embodiments, along the travel direction of the cleaning equipment, the sidewall of the protrusion structure 31 near the cleaning component 20 includes a straight segment 3104, which extends along a second direction. The sidewall of the straight segment 3104 structure is easy to process and has low difficulty.

[0097] In some embodiments, along the travel direction of the cleaning device, the sidewall of the protruding structure 31 near the cleaning component 20 includes a straight segment 3104 and at least two arcuate segments 3105, the arcuate segments 3105 forming a concave arc structure towards the side away from the cleaning component. For example... Figure 7 As shown, at least two arc-shaped segments 3105 are located at opposite ends of the straight segment 3104, and along the traveling direction of the cleaning device, the arc-shaped segments 3105 are arranged around the outer periphery of the front side of the cleaning component 20. The arc lengths of the at least two arc-shaped segments 3105 may be the same or different. The arc-shaped segments 3105 better conform to the contour structure of the front side of the cleaning component 20, thereby increasing the covering area of ​​the first gap 23.

[0098] In some embodiments, along the travel direction of the cleaning device, the side wall of the protruding structure 31 near the cleaning component 20 includes at least two adjacent arc-shaped segments 3105. Along the travel direction of the cleaning device, at least two arc-shaped segments 3105 are arranged around the outer periphery of the front side of the cleaning component 20. Similarly, the arc-shaped segments 3105 fit the contour structure of the front side of the cleaning component 20 more closely, thereby increasing the covering area of ​​the first gap 23.

[0099] In some embodiments, when the cleaning device further includes a walking component 60, the walking component 60 is disposed at the bottom of the main body 10 and located in front of the cleaning component 20. The walking component 60 includes at least one walking wheel. Along the traveling direction of the cleaning device, the protruding structure 31 includes a side wall surface near the side of the cleaning component 20. The outer wall surface of at least one walking wheel near the side of the cleaning component 20 constitutes part of the side wall surface, thereby increasing the overall height of the protruding structure 31 by means of the height of the walking wheel, improving the blocking rate of obstacles, and making the arrangement between the walking component 60, the protruding structure 31 and the cleaning component 20 more compact, thereby improving the space utilization rate of the limited space at the bottom of the main body 10.

[0100] In some embodiments, when the cleaning components 20 include at least two sets, the portion of the sidewall between two adjacent sets of cleaning components 20 is a convex arc segment 1111. The convex arc segment 1111 protrudes towards the cleaning component. The convex arc segment 1111 can be the wall surface of the extension 111 mentioned above near the cleaning component 20, or it can be an arc segment provided in the diameter of two arc segments 3105. The convex arc segment 1111 improves the overall aesthetics of the main body 10 and can cover the gap between two adjacent sets of cleaning components 20. Along the second direction, at least one side of the sidewall of the protruding structure 31 located on opposite sides of the walking wheel is one or more combinations of arc segments 3105 and straight segments 3104 (e.g., Figure 7 The structure consists of two arc-shaped segments 3105, with gaps between the arc-shaped segments 3105 and the straight segments 3104 and the traveling wheels, thereby preventing interference with the movement of the traveling wheels. The traveling wheels may have arc-shaped segments 3105 or straight segments 3104 on both sides, or only on one side. When there are at least two traveling wheels, the arc-shaped segments 3105 and / or the straight segments 3104 may be located only in the area between two adjacent traveling wheels; that is, the protruding structure 31 may be located only between two adjacent traveling wheels.

[0101] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0102] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
