[0038] The present application provides a cleaning device 100, which can include a cleaning robot for cleaning the ground, such as a cleaning robot including a sweeping robot, a mopping robot, or a sweeping and mopping integrated robot, etc., which is not limited here.
[0039] Please refer to Figure 1 The cleaning device 100 includes a cleaning device body 20 and at least one cleaning module 10, the cleaning module 10 is connected with the cleaning device body 20, and the cleaning module 10 is used to extend from the cleaning device body 20 to be close to the edge of the wall, so as to reduce the distance between the cleaning device 100 and the wall surface, thereby increasing the along-wall cleaning range of the cleaning device 100.
[0040] For example, the cleaning device 100 is a mopping robot, the cleaning module 10 can include but is not limited to an edge brush, an edge mop, or a telescopic mop cloth, etc., and the cleaning module 10 is movably mounted on the cleaning device body 20, so that when the cleaning device body 20 moves to the wall edge, the cleaning module 10 can extend from the cleaning device 100 to be close to the edge of the wall, so that the cleaning range of the cleaning module 10 is not limited by the size of the cleaning device body 20, thereby reducing the distance between the cleaning device 100 and the wall surface, thereby increasing the along-wall cleaning range of the cleaning device 100.
[0041] Please refer to Figure 2 The cleaning module 10 includes a cleaning module body 1 and a limiting piece 2.
[0042] The cleaning module body 1 is adapted to be connected with the cleaning device body 20 and used to extend out of the cleaning device body 20, and the limiting piece 2 is installed on the cleaning module body 1. It can be understood that the limiting piece 2 can be fixedly installed on the cleaning module body 1, or the limiting piece 2 can be movably installed on the cleaning module body 1, which is not limited here.
[0043] Please refer to Figure 3 and Figure 4 , the maximum distance between the limiting piece 2 and the centroid of the cleaning module body 1 is greater than the maximum distance between the edge of the cleaning module 10 and the centroid of the cleaning module body 1.
[0044] It can be understood that the cleaning module body 1 is a three-dimensional structure, that is, the centroid of the cleaning module body 1 refers to the volume center of the cleaning module body 1, wherein the cleaning module body 1 can be circular, elliptical, square or other shapes that can achieve wall-following cleaning, which is not limited here.
[0045] For example, please refer to Figure 3 and Figure 4 , the centroid of the cleaning module body 1 can be point M, the maximum distance between the limiting piece 2 and the centroid of the cleaning module body 1 is L1, the maximum distance between the edge of the cleaning module 10 and the centroid of the cleaning module body 1 is L2, and L1>L2.
[0046] In this way, during the process that the cleaning module 10 extends out of the cleaning device body 20 to perform wall-following cleaning, if the cleaning module 10 contacts the wall, the limiting piece 2 will contact the wall first, so that the cleaning module 10 can avoid the cleaning module body 1 directly contacting the wall, thereby avoiding the cleaning module body 1 dirtying or wetting the wall surface, to improve user comfort.
[0047] According to the cleaning module 10 of the embodiment of the present application, by setting the maximum distance between the limiting piece 2 and the centroid of the cleaning module body 1 to be greater than the maximum distance between the edge of the cleaning module 10 and the centroid of the cleaning module body 1, the limiting piece 2 will contact the wall first, so that the cleaning module 10 can avoid the cleaning module body 1 directly contacting the wall, thereby avoiding the cleaning module body 1 dirtying or wetting the wall surface.
[0048] In some embodiments, please refer to Figure 3 and 4The limiting member 2 comprises a guide wheel 21 rotatably mounted on the cleaning module body 1, and the maximum distance L1 between the guide wheel 21 and the centroid of the cleaning module body 1 is greater than the maximum distance L2 between the edge of the cleaning module 10 and the centroid of the cleaning module body 1.
[0049] In this way, when the limiting member 2 contacts the wall, the guide wheel 21 rotates along the wall, so that the guide wheel 21 and the wall form rolling friction, thereby reducing the friction between the limiting member 2 and the wall, and reducing the risk of scratching the wall by the limiting member 2.
[0050] It can be understood that, in some implementations, the cleaning module 10 is rotatably mounted on the cleaning device body 20, and in the embodiment, the guide wheel 21 is rotatably mounted on the cleaning module body 1, so that when the cleaning module 10 rotates relative to the cleaning device body 20 and contacts the wall, the guide wheel 21 can rotate along the wall, so that the guide wheel 21 and the wall form rolling friction, thereby reducing the risk of damage to the wall when the cleaning module 10 rotates.
[0051] In some embodiments, referring to Figure 2 and Figure 3 The cleaning module body 1 comprises a cleaning disc 11, and at least part of the guide wheel 21 is located radially outside the cleaning disc 11.
[0052] It can be understood that the cleaning disc 11 is a circular structure, and in some implementations, a cleaning member such as a cleaning mop can be mounted on the cleaning disc 11, and when the cleaning module 10 extends out of the cleaning device body 20, the cleaning disc 11 can rotate relative to the cleaning device body 20. Since the cleaning disc 11 is a circular structure, it is easier to clean along the wall.
[0053] At least part of the guide wheel 21 is located radially outside the cleaning disc 11, so that the guide wheel 21 contacts the wall first when the cleaning disc 11 contacts the wall. Since the guide wheel 21 is rotatably mounted on the cleaning module body 1, the guide wheel 21 and the wall form rolling friction, thereby reducing the friction between the limiting member 2 and the wall, and reducing the risk of scratching the wall by the limiting member 2.
[0054] In some embodiments, referring to Figure 4 The cleaning module body 1 has a cleaning surface 12, and the extension direction of the rotation axis of the guide wheel 21 is perpendicular to the plane on which the cleaning surface 12 lies.
[0055] It can be understood that the cleaning surface 12 refers to the side of the cleaning module body 1 used to contact the ground to achieve ground cleaning, the extension direction of the rotation axis of the guide wheel 21 is perpendicular to the plane in which the cleaning surface 12 is located, so that the rotation plane of the guide wheel 21 is parallel to the cleaning surface 12, so that after the cleaning module 10 is extended out of the cleaning device body 20, the rotation direction of the guide wheel 21 will not interfere with the movement of the cleaning module 10.
[0056] In some embodiments, referring to Figure 4 , the limiting piece 2 further comprises a connecting piece 22.
[0057] The connecting piece 22 comprises a first connecting part 221 and a second connecting part 222, the first connecting part 221 is connected with the cleaning module body 1, and at least part of the second connecting part 222 is arranged spaced apart from the cleaning module body 1, and the guide wheel 21 is rotatably mounted on the second connecting part 222. Thus, by providing the connecting piece 22, the assembly difficulty of the guide wheel 21 is reduced.
[0058] Referring to Figure 4 , the first connecting part 221 is connected with the cleaning module body 1, and at least part of the second connecting part 222 is arranged spaced apart from the cleaning module body 1, for example, the second connecting part 222 is connected with the first connecting part 221 by bending, and the second connecting part 222 is arranged spaced apart from the cleaning module body 1. In this way, the assembly difficulty of the guide wheel 21 is reduced, and the risk of interference between the guide wheel 21 and the cleaning module body 1 during rotation of the guide wheel 21 is reduced.
[0059] In some embodiments, referring to Figure 2 and Figure 3 , the cleaning module body 1 comprises a cleaning disc 11, and the second connecting part 222 extends along the radial direction of the cleaning disc 11.
[0060] It can be understood that the cleaning disc 11 is a circular structure, and in some implementations, a cleaning piece such as a cleaning mop can be mounted on the cleaning disc 11, and the cleaning disc 11 can rotate relative to the cleaning device body 20 when the cleaning module 10 is extended out of the cleaning device body 20. Since the cleaning disc 11 is a circular structure, it is easier to achieve wall cleaning.
[0061] The second connecting part 222 extends along the radial direction of the cleaning disc 11, so as to reduce the difficulty of arranging the second connecting part 222.
[0062] In some embodiments, referring to Figure 5 , the limiting piece 2 further comprises a connecting shaft 23, and the guide wheel 21 is mounted on the second connecting part 222 through the connecting shaft 23. Thus, the guide wheel 21 can be rotatably connected with the second connecting part 222 through the connecting shaft 23, so as to reduce the difficulty of arranging the guide wheel 21.
[0063] In some embodiments, referring to Figure 5 The connecting piece 22 is provided with a mounting groove 223, as shown in Figure 6 At least part of the guide wheel 21 is rotatably mounted in the mounting groove 223. Thus, by providing the mounting groove 223, the side wall of the mounting groove 223 can limit the guide wheel 21 in the axial direction of the connecting shaft 23, thereby enhancing the structural stability of the guide wheel 21.
[0064] For example, the connecting shaft 23 is connected between the two oppositely arranged side walls of the mounting groove 223, so that the connecting shaft 23 can make full use of the space in the mounting groove 223 to achieve installation. The guide wheel 21 is sleeved on the connecting shaft 23, so that part of the guide wheel 21 is located in the mounting groove 223, and the side wall of the mounting groove 223 can limit the guide wheel 21 in the axial direction of the connecting shaft 23, thereby enhancing the structural stability of the guide wheel 21.
[0065] In some embodiments, referring to Figure 5 The second connecting part 222 is provided with two baffles 224, which are arranged in a spaced manner to define the mounting groove 223. Thus, by providing the two baffles 224, the mounting groove 223 is defined by the two baffles 224, thereby reducing the design difficulty of the mounting groove 223.
[0066] In some embodiments, referring to Figure 6 The connecting shaft 23 is mounted in the mounting groove 223, and the guide wheel 21 is rotatably connected with the connecting shaft 23.
[0067] For example, the connecting shaft 23 is connected between the two oppositely arranged side walls of the mounting groove 223, so that the connecting shaft 23 can make full use of the space in the mounting groove 223 to achieve installation. The guide wheel 21 is sleeved on the connecting shaft 23, so that part of the guide wheel 21 is located in the mounting groove 223, and the side wall of the mounting groove 223 can limit the guide wheel 21 in the axial direction of the connecting shaft 23, thereby enhancing the structural stability of the guide wheel 21.
[0068] In some embodiments, referring to Figure 6 and Figure 7 At least part of the outer peripheral wall of the end of the second connecting part 222 away from the first connecting part 221 is formed as an arc surface 2221.
[0069] Thus, the end of the second connecting part 222 away from the first connecting part 221 is smoother, so that in the case where the end of the second connecting part 222 away from the first connecting part 221 protrudes from the edge of the cleaning module body 1, even if the guide wheel 21 is damaged and the end of the second connecting part 222 away from the first connecting part 221 contacts the wall, the damage to the wall can be reduced.
[0070] In some embodiments, referring to Figure 2 and Figure 3 The connecting piece 22 is integrally formed with the cleaning module body 1, so as to improve the connecting strength of the connecting piece 22 and the cleaning module body 1, and the connecting piece 22 and the cleaning module body 1 can be integrally formed to reduce production cost.
[0071] In other embodiments, the connecting piece 22 is detachably connected with the cleaning module body 1, so that the user can flexibly select and install the connecting piece 22 according to actual use requirements. The connecting piece 22 and the cleaning module body 1 can be connected by clamping, inserting, magnetic attraction, or bolt connection, which is not limited here.
[0072] In some embodiments, referring to Figure 4 The cleaning module body 1 has a cleaning surface 12, and the limiting piece 2 is located on the opposite side of the cleaning surface 12 of the cleaning module body 1.
[0073] It can be understood that the cleaning surface 12 refers to the side of the cleaning module body 1 used to contact the ground to achieve ground cleaning. The limiting piece 2 is located on the opposite side of the cleaning surface 12 of the cleaning module body 1, which can reduce the space occupation of the limiting piece 2 on one side of the cleaning surface 12, thereby facilitating the increase of the ground contact area of the cleaning surface 12, and avoiding the interference of the limiting piece 2 with the ground.
