[0037] In the related art, please refer to Figure 1. Figure 1 is a plan view of the cleaning equipment in the related art. The cleaning equipment includes a main body 10 and a cleaning tray 20. The cleaning tray 20 adopts a disc-shaped rotating cloth. The cloth protrudes from the body. When the cloth stops rotating, part of the cloth is still exposed outside the body and cannot be completely covered by the body.

[0038] To address the aforementioned technical problems, please refer to Figure 2, which is a plan view of one embodiment of the cleaning device 1000 provided in this application. This application provides a cleaning device 1000, which can be a cleaning robot. The cleaning device 1000 can at least perform functions such as sweeping and mopping. The cleaning device 1000 includes a device body 100 and a mop assembly 200. The device body 100 has a bottom surface 110, which is the side of the device body 100 facing the surface to be cleaned. The device body 100 can serve as the basic carrier of the cleaning device 1000. The device body 100 can be a one-piece structure or a combined structure formed by the cooperation of multiple components. The device body 100 provides support and protection for other components of the cleaning device 1000. A mop assembly 200 is disposed on the bottom surface 110. The mop assembly 200 includes a mop unit 210, which includes a mop body 211 and a rotating shaft 212. The rotating shaft 212 is connected between the device body 100 and the mop body 211. The rotating shaft 212 has a rotation center. The mop body 211 has a first posture and a second posture. In the first posture, the orthographic projection of the mop body 211 onto the plane of the bottom surface 110 is located within the bottom surface 110. In the second posture, the outline of the orthographic projection of the mop body 211 onto the plane of the bottom surface 110 is at least partially located outside the bottom surface 110.

[0039] In this embodiment, by designing the mop body 211 to have a first posture, in which the orthographic projection of the mop body 211 onto the plane of the bottom surface 110 is located within the bottom surface 110, the mop body 211 can be completely covered by the body when the cleaning device 1000 is hovering at a fixed point, improving the aesthetics of the cleaning device 1000. Furthermore, by designing the mop body 211 to have a second posture, in which the outline of the orthographic projection of the mop body 211 onto the plane of the bottom surface 110 is at least partially located outside the bottom surface 110, the contact area between the mop body 211 and the surface to be cleaned can be increased when cleaning the surface, thereby improving cleaning efficiency.

[0040] The cleaning equipment 1000 of this application can be either a circular machine or a square-circle machine. For ease of understanding and explanation, Figures 2 to 4 use a circular machine for illustration, while Figures 5 to 10 use a square-circle machine for illustration.

[0041] In one embodiment, the minimum distance between the rotation center and the outline of the mop body 211 is less than or equal to the minimum distance between the rotation center and the outline of the bottom surface 110, and the maximum distance between the rotation center and the outline of the mop body 211 is greater than the minimum distance between the rotation center and the outline of the bottom surface 110.

[0042] In the technical solution of this embodiment, please refer to Figures 2 to 4. Figure 3 is a plan view of another embodiment of the cleaning device 1000 provided in this application, and Figure 4 is a plan view of another embodiment of the cleaning device 1000 provided in this application. By designing the minimum distance between the rotation center and the outline of the mop body 211 to be less than or equal to the minimum distance between the rotation center and the outline of the bottom surface 110, the mop body 211 can be completely covered by the machine body when the cleaning device 1000 is suspended at a fixed point, thus improving the aesthetics of the cleaning device 1000. By designing the maximum distance between the rotation center and the outline of the mop body 211 to be greater than the minimum distance between the rotation center and the outline of the bottom surface 110, part of the mop body 211 can extend beyond the machine body when cleaning the surface to be cleaned, thereby increasing the contact area between the mop body 211 and the surface to be cleaned, and thus improving the cleaning efficiency of the cleaning device 1000.

[0043] In one embodiment, the mop assembly 200 includes at least two mop units 210, wherein the distance between the rotation centers of two adjacent mop units 210 is less than the sum of the maximum distances between the two rotation centers and the contour of the mop body 211.

[0044] In the technical solution of this embodiment, by designing the distance between the rotation centers of two adjacent mop units 210 to be less than the sum of the maximum distances between the two rotation centers and the outline of the mop body 211, the two adjacent mop units 210 can be squeezed together in the middle when rotating, leaving no gaps during the cleaning process, thereby improving the cleaning efficiency of the cleaning equipment 1000.

[0045] In one embodiment, the mop bodies 211 of two adjacent mop units 210 are mirror-symmetrical with respect to the first spindle of the cleaning device 1000.

[0046] In this embodiment, the mop bodies 211 of the two mop units 210, which are mirror-symmetrical with respect to the first spindle of the cleaning device 1000, can cooperate with each other, allowing the edge portions of the mop bodies 211 to make more full contact and squeeze, thereby effectively reducing uncleaned areas and improving cleaning coverage. Furthermore, when the cleaning device 1000 moves forward or turns, the mop bodies 211, which are mirror-symmetrical with respect to the first spindle of the cleaning device 1000, can evenly distribute the downward pressure, facilitating good contact between the mop bodies 211 and the surface to be cleaned and reducing the risk that some mop bodies 211 may not effectively clean the surface due to uneven pressure.

[0047] In one embodiment, please refer to Figure 2, the mop body 211 is elliptical.

[0048] In this embodiment, the elliptical mop body 211 can achieve a larger area coverage during the movement of the cleaning device 1000. Its long axis can wipe a wider area at once as the cleaning device 1000 moves forward, thereby improving cleaning efficiency. Furthermore, when the cleaning device 1000 moves along the corner of a room, the long axis of the elliptical mop body 211 can better fit against the two sides of the corner, allowing for deeper cleaning of corner areas and reducing cleaning dead spots.

[0049] In one embodiment, the outline of the mop body 211 includes multiple curves.

[0050] In this embodiment, referring to Figure 3, the outline of the mop body 211 includes two curved sections. One curved section coincides with the outline of a portion of the bottom surface 110 of the device body 100, while the other curved section is an arc-shaped edge convex outward from the center of rotation. The fact that one curved section of the mop body 211 coincides with the outline of a portion of the bottom surface 110 of the device body 100 makes it easier for users to align the mop body 211 with the corresponding position on the bottom surface 110 of the device body 100 for installation, greatly improving user convenience during daily use and maintenance. The other curved section of the mop body 211, an arc-shaped edge convex outward from the center of rotation, allows the cleaning device 1000 to clean narrow areas more flexibly, reducing cleaning dead spots and thus improving cleaning efficiency.

[0051] In this embodiment, referring to Figure 4, the outline of the mop body 211 includes three curved sections. The first curved section coincides with the outline of a portion of the bottom surface 110 of the device body 100. The second and third curved sections are respectively arc-shaped edges convex outward from the rotation center. The fact that one curved section of the mop body 211 coincides with the outline of a portion of the bottom surface 110 of the device body 100 makes it easier for users to align the mop body 211 with the corresponding position on the bottom surface 110 of the device body 100 for installation, greatly improving user convenience during daily use and maintenance. The second and third curved sections are respectively arc-shaped edges convex outward from the rotation center. This design allows the edge portion of the mop body 211 to cover a larger area during rotation, thereby improving cleaning efficiency.

[0052] In one embodiment, the device body 100 has a receiving portion 120 that is recessed relative to the bottom surface 110. The receiving portion 120 is used to receive the mop unit 210. The cleaning device 1000 includes a first driving assembly, which is disposed between the device body 100 and the mop unit 210. The first driving assembly is used to drive the mop body 211 to extend out of the receiving portion 120 along a first direction X or to retract into the receiving portion 120 in a direction opposite to the first direction X. The first direction X is the direction from the bottom surface 110 toward the surface to be cleaned.

[0053] In this embodiment, the mop body 211 is vertically and retractably disposed within the recessed receiving portion 120 of the bottom surface 110 of the device body 100. Referring to Figures 5 and 6, Figure 5 is a side view of the cleaning device 1000 provided in this embodiment with the mop body 211 retracted into the receiving portion 120, and Figure 6 is a front view of the cleaning device 1000 provided in this embodiment with the mop body 211 retracted into the receiving portion 120. When the cleaning device 1000 is about to reach the carpet, the first drive assembly drives the mop body 211 to retract into the receiving portion 120 along the direction from the surface to be cleaned towards the bottom surface 110, preventing water on the mop body 211 from wetting the carpet. Referring to Figures 7 and 8, Figure 7 is a side view of the cleaning device 1000 provided in this embodiment with the mop body 211 extending out of the receiving portion 120, and Figure 8 is a top view of the cleaning device 1000 provided in this embodiment with the mop body 211 extending out of the receiving portion 120. When the cleaning device 1000 leaves the carpet, the first drive assembly drives the mop body 211 to extend the receiving part 120 along the bottom surface 110 toward the surface to be cleaned, and to contact the surface to be cleaned so as to clean the surface.

[0054] Optionally, the cleaning device 1000 also includes a processor and a detection component, both of which are connected to the processor. The detection component is used to detect the road conditions of the cleaning device 1000. For example, the detection component can detect whether there is carpet within a preset distance in the direction of travel of the cleaning device 1000. If carpet is detected within the preset distance in the direction of travel of the cleaning device 1000, it indicates that the cleaning device 1000 is about to run into the carpet area. The preset distance can be the distance between the front end of the cleaning device 1000 in the direction of travel and the edge of the carpet, or it can be the distance between the edge of the mop body 211 near the carpet and the edge of the carpet. When the detection component detects that the cleaning device 1000 is about to run into the carpet, it sends a signal. The processor responds to the signal sent by the detection component and controls the first drive component to drive the mop body 211 to retract into the receiving part 120 along the direction of the surface to be cleaned toward the bottom surface 110, thereby preventing water on the mop body 211 from wetting the carpet.

[0055] In one embodiment, the cleaning device 1000 includes a second drive assembly 300 and a blocking member 400. The second drive assembly 300 is disposed between the device body 100 and the blocking member 400. The blocking member 400 is located at the opening of the receiving portion 120. The second drive assembly 300 is used to drive the blocking member 400 to move along a second direction Y so as not to block the mop body 211 or to move in a direction opposite to the second direction Y so as to block the mop body 211. The first direction X and the second direction Y are perpendicular.

[0056] In this embodiment, when the cleaning device 1000 is about to reach the carpet, the second drive assembly 300 drives the blocking member 400 to close the opening, that is, to move it to the side of the mop body 211 facing the surface to be cleaned, thereby blocking the mop body 211 and reducing the risk of residual water on the mop body 211 dripping and wetting the carpet. Additionally, the blocking member 400 can be located on the outside of the bottom surface 110 to simplify its installation; the blocking member 400 can also be housed within the device body 100, flush with the bottom surface 110 or located on the inside of the bottom surface 110, achieving an embedded effect and increasing aesthetics. When the cleaning device 1000 is about to run onto the carpet, the second drive assembly 300 first drives the blocking member 400 to move along the second direction Y to open the opening. At this time, the mop body 211 is in an unblocked state. Then, the first drive assembly drives the mop body 211 to retract into the receiving part 120 along the direction from the surface to be cleaned toward the bottom surface 110. Finally, the second drive assembly 300 drives the blocking member 400 to move in the opposite direction to the second direction Y to close the opening. At this time, the mop body 211 is in a blocked state.

[0057] In one embodiment, please refer to FIG9, which is an exploded view of the cleaning device 1000 provided in the embodiment of this application. The second drive assembly 300 includes a drive wheel 330, and the shield 400 includes a driven bar 420. The drive wheel 330 and the driven bar 420 are engaged.

[0058] In the technical solution of this embodiment, the second drive component 300 and the blocking component 400 are connected by gear meshing with the driven bar 420, so that when the drive wheel 330 rotates, it can drive the blocking component 400 to move stably.

[0059] Optionally, please refer to Figure 10, which is a cross-sectional structural diagram of one embodiment of the cleaning device 1000 provided in this application. The shielding member 400 further includes a shielding plate 410, and the driven strip 420 is disposed on the shielding plate 410. In this application, the continuous rotation of the drive wheel 330 can uniformly push the driven strip 420, thereby driving the shielding member 400 to move stably.

[0060] Optionally, referring to Figure 9, the second drive assembly 300 further includes a bracket 320 and a drive motor 310. The bracket 320 is mounted on the main body 100, and the drive motor 310 is mounted on the bracket 320. The drive wheel 330 is connected to the drive motor 310. The drive motor 310 drives the drive wheel 330 to rotate, and the rotation of the drive wheel 330 can evenly push the driven bar 420, thereby driving the blocking member 400 to move stably.

[0061] In one embodiment, the device body 100 further includes a telescopic rod 500, which is connected between the device body 100 and the shielding member 400.

[0062] In this embodiment, the extension of the telescopic rod 500 can drive the blocking member 400 to move along the second direction Y, and the retraction of the telescopic rod 500 can drive the blocking member 400 to move in the opposite direction to the second direction Y. The telescopic rod 500 connects the equipment body 100 and the blocking member 400, and the telescopic rod 500 can support the blocking member 400, preventing it from swaying during movement and thus improving the stability of the blocking member 400's movement. In addition, the telescopic rod 500 can also limit the maximum extension distance of the blocking member 400, reducing the risk of the blocking member 400 detaching from the equipment body 100 during movement.

[0063] Optionally, please refer to Figures 11 to 13. Figure 11 is a three-dimensional structural diagram of the telescopic rod 500 after retraction according to an embodiment of this application. Figure 12 is a three-dimensional structural diagram of the telescopic rod 500 after extension according to an embodiment of this application. Figure 13 is an exploded view of the telescopic rod 500 according to an embodiment of this application. The telescopic rod 500 includes a first rod segment 510, a second rod segment 520, a third rod segment 530, and a fourth rod segment 540 that are sequentially connected. During the extension of the telescopic rod 500, the second rod segment 520, the third rod segment 530, and the fourth rod segment 540 move away from the main body 100 of the equipment. During the retraction of the telescopic rod 500, the fourth rod segment 540 retracts into the third rod segment 530, the third rod segment 530 retracts into the second rod segment 520, and the second rod segment 520 retracts into the first rod segment 510.

[0064] Optionally, an end cap 550 is provided at the end of the fourth rod segment 540 away from the third rod segment 530. The end cap 550 can seal the telescopic rod 500 to prevent dust or moisture from entering the telescopic rod 500 and causing contamination.

[0065] Optionally, the shield 400 also includes a pressure cap 430, which is disposed on the shield 410 and can be used to fix the telescopic rod 500.

[0066] In one embodiment, the shielding member 400 has a first end and a second end disposed opposite to each other, the second direction Y, the direction from the first end toward the second end and the travel direction of the cleaning device 1000 are the same, and the second end is provided with a support wheel 600.

[0067] In this embodiment, by providing a support wheel 600 at the second end of the shielding member 400, the support wheel 600 can slide on the surface of the base station during the operation of the cleaning device 1000, thus preventing friction between the cleaning device 1000 and the base station surface. Additionally, the support wheel 600 can support the shielding member 400, preventing it from scratching the surface to be cleaned due to gravity during movement.

[0068] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
