[0032] Although relative terms such as "upper", "lower", etc. are used herein to describe one component's relationship to another component as illustrated in the figures, such terminology is used for convenience only and is not intended to limit the scope of the disclosure to the position of the components as shown in the figures. It is to be understood that if the device of the figures were turned over, the components described as being on "top" would then be oriented on the "bottom". When a structure is on another structure, it can mean that the structure is formed integrally with the other structure, or that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure via another structure.

[0033] The terms "one", "a", "an", "the", "said", are used to indicate the existence of one or more than one element / component / etc.; the terms "include" and "has" are used to indicate an open-ended inclusion of one or more elements / components / etc. in the description of the embodiments; the terms "first" and "second" etc. are used to distinguish one element / component / etc. from another element / component / etc. and are not used to limit the quantity of the elements / components / etc.

[0034] Some embodiments of the present disclosure provide a cleaning system, which can include a cleaning base station and a cleaning device. The cleaning device can be parked on the cleaning base station, or the cleaning device can be docked with the cleaning base station, or the cleaning device can be parked on and docked with the cleaning base station. When the cleaning device is parked on the cleaning base station, the cleaning base station can charge, water, and clean the cleaning device. The cleaning device can be a robot vacuum cleaner, a robot scrubber, a robot mop, or the like.

[0035] As shown in Figure 1 , the cleaning device can include a cleaning main body 01 and a cleaning assembly 02, the cleaning assembly 02 can be connected to the cleaning main body 01 to clean a surface to be cleaned by using the cleaning assembly 02. The cleaning assembly 02 can include a bracket 1 and a cleaning piece 2. The bracket 1 can include a main body 12 and a moving piece 13, the cleaning assembly 02 can be connected to the cleaning main body 01 through the main body 12, the moving piece 13 can be movably connected to the main body 12, and the moving piece 13 can have an edge portion 11, the edge portion 11 can be located at an edge region of the bracket 1. The cleaning piece 2 can be connected to at least the edge portion 11, the cleaning piece 2 can clean the surface to be cleaned, and the cleaning piece 2 can be a mop, a brush, a scraping strip, or the like.

[0036] As shown in Figure 2 , the bracket 1 can have a first working state and a second working state. When the bracket 1 is in the first working state, the edge portion 11 and a central axis S1 of the bracket 1 can have a first distance L1. When the bracket 1 is in the second working state, the edge portion 11 and the central axis S1 of the bracket 1 can have a second distance L2, and the second distance L2 can be greater than the first distance L1. Thus, the distance between the edge portion 11 and the central axis S1 of the bracket 1 is different, so that the cleaning range of the cleaning piece 2 is different when the bracket 1 is in the first working state and in the second working state.

[0037] Since the second distance L2 is greater than the first distance L1, the edge portion 11 can protrude outward when the bracket 1 is in the second working state, so that the cleaning piece 2 connected to the edge portion 11 can protrude outward, thereby increasing the cleaning range of the cleaning piece 2, so that the cleaning piece 2 can clean the cleaning dead angle of the wall corner, the table leg, or the like, and the cleaning effect of the cleaning assembly 02 can be improved. At the same time, when the cleaning range of the cleaning piece 2 is expanded, the cleaning efficiency of the cleaning assembly 02 can be improved.

[0038] In addition, when the support 1 is switched to the first working state, the edge portion 11 can be retracted, so that the cleaning member 2 connected with the edge portion 11 can be retracted synchronously, thereby the size of the cleaning assembly 02 can be reduced, the space occupied by the cleaning assembly 02 is reduced, so that the cleaning equipment loaded with the cleaning assembly 02 is facilitated to pass through a narrower space or is facilitated to be parked in a cleaning base station, meanwhile, the cleaning assembly 02 can be used to clean a narrower space, and the cleaning effect of the cleaning assembly 02 can be further improved.

[0039] It should be noted that the extension of the cleaning member 2 described above can be understood as that the entire cleaning member 2 extends with the edge portion 11, or can be understood as that the part of the cleaning member 2 connected with the edge portion 11 extends with the edge portion 11.

[0040] In some embodiments, when the support 1 is switched from the first working state to the second working state, the moving member 13 can move in a direction away from the central axis S2 of the main body member 12, thereby driving the cleaning member 2 connected with the moving member 13 to move in a direction away from the central axis S2 of the main body member 12, that is, the moving member 13 can drive the entire cleaning member 2 to move in a direction away from the central axis S2 of the main body member 12, or the moving member 13 can drive the part of the cleaning member 2 connected with the edge portion 11 to move in a direction away from the central axis S2 of the main body member 12, so that the cleaning range of the cleaning member 2 can be increased.

[0041] Alternatively, when the support 1 is switched from the second working state to the first working state, the moving member 13 can move in a direction close to the central axis S2 of the main body member 12, thereby driving the cleaning member 2 connected with the moving member 13 to move in a direction close to the central axis S2 of the main body member 12, that is, the moving member 13 can drive the entire cleaning member 2 to move in a direction close to the central axis S2 of the main body member 12, or the moving member 13 can drive the part of the cleaning member 2 connected with the edge portion 11 to move in a direction close to the central axis S2 of the main body member 12, so that the size of the cleaning assembly 02 can be reduced, and the passability of the cleaning equipment can be improved.

[0042] The cleaning host 01 can be configured to drive the main body member 12 to rotate, so that the main body member 12 drives the moving member 13 and the cleaning member 2 to rotate, the contact time and the contact pressure of the cleaning member 2 with the surface to be cleaned can be increased, and the cleaning effect of the cleaning assembly 02 on the surface to be cleaned can be improved.

[0043] The main body 12 can have a first rotation state and a second rotation state, that is, the cleaning main machine 01 can drive the main body 12 to rotate in the first rotation state, or the cleaning main machine 01 can drive the main body 12 to rotate in the second rotation state. When the main body 12 is in the first rotation state, the moving part 13 can move away from the central axis S2 of the main body 12, and when the main body 12 is in the second rotation state, the moving part 13 can move towards the central axis S2 of the main body 12, wherein the rotation direction of the main body 12 in the first rotation state is opposite to the rotation direction of the main body 12 in the second rotation state.

[0044] That is, it can be understood that when the main body 12 rotates in the first rotation state, the moving part 13 can drive the cleaning part 2 to extend outward to increase the cleaning range of the cleaning assembly 02; when the main body 12 reversely rotates in the second rotation state, the moving part 13 can drive the cleaning part 2 to retract to reduce the size of the cleaning assembly 02. In this way, the extension and retraction movement of the moving part 13 and the cleaning part 2 can be directly controlled by rotation, so that it is no longer necessary to set additional auxiliary elements to control the extension and retraction movement of the moving part 13 and the cleaning part 2, which can simplify the difficulty of controlling the extension and retraction movement of the moving part 13 and the cleaning part 2, and reduce the manufacturing cost and control cost of the cleaning assembly 02.

[0045] Further, when the main body 12 is in the first rotation state and the rotation speed of the main body 12 is greater than or equal to a first preset speed, the moving part 13 can move away from the central axis S2 of the main body 12. In this way, the preset condition of the extension of the moving part 13 can be set to avoid the extension of the moving part 13 and the cleaning part 2 connected with the moving part 13. The rotation speed of the preset condition of the extension of the moving part 13 is not specifically limited in the present disclosure, and can be selected and set according to the actual situation, which is within the protection scope of the present disclosure.

[0046] When the main body 12 is in the first rotation state and the rotation speed of the main body 12 is less than or equal to a second preset speed, the moving part 13 can move towards the central axis S2 of the main body 12. In this way, the preset condition of the retraction of the moving part 13 can be set to ensure that the moving part 13 and the cleaning part 2 can be timely retracted when needed, so as to facilitate the storage of the cleaning assembly 02, and also facilitate the cleaning equipment to pass through narrow spaces. The rotation speed of the preset condition of the retraction of the moving part 13 is not specifically limited in the present disclosure, and can be selected and set according to the actual situation, which is within the protection scope of the present disclosure.

[0047] The first preset speed and the second preset speed can be the same, and when the rotation speed of the main body 12 is greater than or equal to the preset speed, the moving part 13 can move away from the central axis S2 of the main body 12, and when the rotation speed of the main body 12 is less than the preset speed, the moving part 13 can move towards the central axis S2 of the main body 12.

[0048] As shown in Figure 4 and Figure 5 The main body 12 can have a first connecting part 122, and the moving part 13 can have a second connecting part 132. The bracket 1 can further include an elastic part 14, which can include but is not limited to a spring, a rubber ring, etc. The elastic part 14 can be connected to the first connecting part 122 and the second connecting part 132, and when the bracket 1 is in the second working state, the elastic part 14 is in a stretched state. Thus, when the bracket 1 is in the second working state, the elastic part 14 can have a restoring force that can drive the moving part 13 to move towards the central axis of the main body 12, so that the bracket 1 is switched from the second working state to the first working state.

[0049] For example, when it is necessary to expand the cleaning range of the cleaning part 2, the cleaning host 01 can drive the main body 12 to rotate in the first rotation state, and the moving part 13 moves away from the central axis S2 of the main body 12 under the action of centrifugal force, so that the cleaning part 2 is extended. At this time, the moving part 13 can stretch the elastic part 14, so that the elastic part 14 has a restoring force inside. When it is necessary to reduce the size of the cleaning assembly 02, the cleaning host 01 can drive the main body 12 to rotate in the second rotation state, and the elastic part 14 can drive the moving part 13 to move towards the central axis S2 of the main body 12 by using the restoring force, so that the cleaning part 2 is retracted.

[0050] Further, when it is necessary to expand the cleaning range of the cleaning part 2, the cleaning host 01 can drive the main body 12 to rotate at a speed greater than or equal to the first preset speed, and at this time, the centrifugal force of the moving part 13 is greater than the restoring force of the elastic part 14, and the moving part 13 can move away from the central axis S2 of the main body 12 under the action of centrifugal force, so that the cleaning part 2 is extended. At this time, the moving part 13 can stretch the elastic part 14, so that the elastic part 14 has a restoring force inside. When it is necessary to reduce the size of the cleaning assembly 02, the cleaning host 01 can drive the main body 12 to rotate at a speed less than or equal to the second preset speed, and at this time, the centrifugal force of the moving part 13 is less than the restoring force of the elastic part 14, and the moving part 13 can move towards the central axis S2 of the main body 12 under the action of the restoring force, so that the cleaning part 2 is retracted.

[0051] In some embodiments, as Figures 3 to 5As shown, the main body 12 can be provided with a first guide portion 121, and the moving member 13 can be provided with a second guide portion 131, the second guide portion 131 can be in sliding fit with the first guide portion 121, so as to limit the movement of the moving member 13 in the direction away from or close to the rotation axis of the main body 12, so as to ensure that the moving member 13 can move along the correct path.

[0052] One of the first guide portion 121 and the second guide portion 131 can include a guide groove, and the other can include a guide block, that is, the first guide portion 121 can include a guide groove, and the second guide portion 131 can include a guide block; or, the first guide portion 121 can include a guide block, and the second guide portion 131 can include a guide groove. The guide block can be in sliding fit in the guide groove, and one end of the guide groove can be closer to the central axis S2 of the main body 12 relative to the other end, so that the moving member 13 can only be able to move along the extension direction of the guide groove, so as to further improve the accuracy of the movement direction of the moving member 13.

[0053] Further, the first guide portion 121 can include a guide groove, and the second guide portion 131 can include a guide block, the guide groove can be an arc-shaped groove, when the main body 12 is in the first rotation state, the rotation direction of the main body 12 can be the direction in which the center of the arc-shaped groove points to the arc-shaped groove, at this time, the moving member 13 can move in the direction away from the central axis S2 of the main body 12 under the action of the arc-shaped groove and the centrifugal force, so as to realize the extension of the moving member 13 and the cleaning member 2. When the main body 12 is in the second rotation state, the rotation direction of the main body 12 can be the direction in which the arc-shaped groove points to the center of the arc-shaped groove, at this time, the moving member 13 can move in the direction close to the central axis S2 of the main body 12 under the action of the arc-shaped groove and the restoring force of the elastic member 14, so as to realize the retraction of the moving member 13 and the cleaning member 2.

[0054] But not limited to this, the shape of the guide groove can also not be limited to the arc-shaped groove, for example: the shape of the guide groove can also be a linear groove, which can be selected and set according to the actual situation, which is within the protection scope of the present disclosure.

[0055] In some embodiments, as Figure 3 and Figure 5As shown, the moving part 13 can include a first support part 133 and a second support part 134. One end of the first support part 133 can be movably connected with the main body part 12, and the second support part 134 can be located at one end of the first support part 133 away from the central axis of the main body part 12, and the edge part 11 of the bracket 1 can be located at the second support part 134. Wherein, the size L4 of the second support part 134 in the circumferential direction Z of the main body part 12 is greater than the size L3 of the first support part 133 in the circumferential direction Z of the main body part 12, and such arrangement can increase the connection area of the moving part 13 and the cleaning part 2, so as to improve the connection stability and flatness of the cleaning part 2.

[0056] One side of the second support part 134 away from the central axis S2 of the main body part 12 can be an arc surface, and the center of the arc surface can be close to the central axis S2 of the main body part 12 relative to the arc surface, that is, the outer side of the second support part 134 can be an arc surface, and the arc surface can be a convex surface. Such arrangement, as shown in Figure 2 and Figure 3 As shown, when the adjacent two cleaning assemblies 02 meet during rotation, the respective arc surfaces can be used for guiding, so as to avoid hard collision of the moving parts 13 of the adjacent two cleaning assemblies 02, which can improve the smoothness of the rotation of the cleaning assembly 02, and can reduce the probability of damage of the moving parts 13 due to hard collision. And, as shown in Figure 3 and Figure 6 As shown, when the obstacle 3 is located on the rotating path W1 of the moving part 13, the arc surface can be used for guiding the moving part 13, so as to avoid hard collision of the adjacent moving part 13 and the obstacle 3, which can improve the smoothness of the rotation of the cleaning assembly 02, and can reduce the probability of damage of the moving part 13 due to hard collision.

[0057] One side of the second support part 134 close to the central axis S2 of the main body part 12 can also be an arc surface, and the center of the arc surface can be close to the central axis of the main body part 12 relative to the arc surface, that is, the inner side of the second support part 134 can also be an arc surface, and the arc surface can also be a convex surface. The curvature of one side of the second support part 134 close to the central axis S2 of the main body part 12 can be the same as the curvature of one side of the second support part 134 away from the central axis S2 of the main body part 12, but is not limited thereto. The curvature of one side of the second support part 134 close to the central axis S2 of the main body part 12 and the curvature of one side of the second support part 134 away from the central axis S2 of the main body part 12 are not limited in the present disclosure, and can be selected and arranged according to actual conditions, which are all within the protection scope of the present disclosure.

[0058] In some embodiments, as shown in Figure 3As shown, the support 1 can include a plurality of moving pieces 13, which can be arranged at intervals in the circumferential direction Z of the main body piece 12, so that the number of moving pieces 13 connected to the cleaning piece 2 can be increased, the connection points of the cleaning piece 2 can be increased, and the connection stability of the cleaning piece 2 can be improved. Moreover, in this way, the cleaning piece 2 can be extended outward in the circumferential direction Z of the main body piece 12, and the flatness of the cleaning piece 2 after extension can be ensured, so as to improve the cleaning effect of the cleaning piece 2 after extension.

[0059] When the support 1 is provided with a plurality of moving pieces 13, the main body piece 12 can be provided with a plurality of first guide portions 121, which can correspond to the second guide portions 131 of the plurality of moving pieces 13 one by one, and each first guide portion 121 can be in sliding fit with the corresponding second guide portion 131.

[0060] In some embodiments of the present disclosure, as shown in Figure 1 and Figure 2 As shown, the cleaning device can at least include a first cleaning assembly 021 and a second cleaning assembly 022 arranged adjacent to each other, and the cleaning host 01 can be configured to simultaneously drive the main body piece 12 of the first cleaning assembly 021 and the main body piece 12 of the second cleaning assembly 022 to rotate, so as to increase the cleaning range of the cleaning device and improve the cleaning effect of the cleaning device by at least two cleaning assemblies 02.

[0061] In some embodiments, when the first guide portion 121 of the main body piece 12 includes an arc-shaped guide groove, the bending direction of the guide groove of the first cleaning assembly 021 can be opposite to the bending direction of the guide groove of the second cleaning assembly 022. The cleaning host 01 can be configured to simultaneously drive the main body piece 12 of the first cleaning assembly 021 and the main body piece 12 of the second cleaning assembly 022 to rotate in opposite directions.

[0062] For example, the cleaning host 01 can be configured to drive the main body piece 12 of the first cleaning assembly 021 to rotate in the X direction, and can drive the main body piece 12 of the second cleaning assembly 022 to rotate in the Y direction, so that the moving piece 13 of the first cleaning assembly 021 and the moving piece 13 of the second cleaning assembly 022 can move synchronously in a direction away from the central axis S2 of the respective main body piece 12.

[0063] Alternatively, the cleaning host 01 can be configured to drive the main body piece 12 of the first cleaning assembly 021 to rotate in a direction opposite to the X direction, and can drive the main body piece 12 of the second cleaning assembly 022 to rotate in a direction opposite to the Y direction, so that the moving piece 13 of the first cleaning assembly 021 and the moving piece 13 of the second cleaning assembly 022 can move synchronously in a direction close to the central axis S2 of the respective main body piece 12.

[0064] In some embodiments, when the first guide portion 121 of the main body 12 comprises an arc-shaped guide slot, the bending direction of the guide slot of the first cleaning assembly 021 can be the same as the bending direction of the guide slot of the second cleaning assembly 022. The cleaning main machine 01 can be configured to simultaneously drive the main body 12 of the first cleaning assembly 021 and the main body 12 of the second cleaning assembly 022 to rotate in the same direction, so that the moving part 13 of the first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022 can be simultaneously moved away from the central axis S2 of the respective main body 12, or can be simultaneously moved towards the central axis S2 of the respective main body 12.

[0065] In some embodiments, when the first guide portion 121 of the main body 12 comprises a linear guide slot, the cleaning main machine 01 can be configured to simultaneously drive the main body 12 of the first cleaning assembly 021 and the main body 12 of the second cleaning assembly 022 to rotate in the same direction, so that the moving part 13 of the first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022 can be simultaneously moved away from the central axis S2 of the respective main body 12, or can be simultaneously moved towards the central axis S2 of the respective main body 12.

[0066] Further, when the first guide portion 121 of the main body 12 comprises a linear guide slot, the cleaning main machine 01 can also be configured to simultaneously drive the main body 12 of the first cleaning assembly 021 and the main body 12 of the second cleaning assembly 022 to rotate in opposite directions, so that the moving part 13 of the first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022 can be simultaneously moved away from the central axis S2 of the respective main body 12, or can be simultaneously moved towards the central axis S2 of the respective main body 12.

[0067] In some embodiments, as Figure 1 and Figure 2As shown, the rotation path W11 of the moving part 13 of the first cleaning assembly 021 and the rotation path W12 of the moving part 13 in the second cleaning assembly 022 can have an overlapping area 02a, so that the rotation path of the cleaning part 2 connected with the moving part 13 of the first cleaning assembly 021 and the rotation path of the cleaning part 2 connected with the moving part 13 of the second cleaning assembly 022 can also have an overlap during rotation, which can avoid the gap between the cleaning part 2 of the first cleaning assembly 021 and the cleaning part 2 of the second cleaning assembly 022 during rotation, effectively prevent the occurrence of missed cleaning area, and further improve the cleaning effect of the cleaning equipment.

[0068] Further, the arc surface of the moving part 13 in the first cleaning assembly 021 and the arc surface of the moving part 13 in the second cleaning assembly 022 can at least contact each other when rotating to the overlapping area 02a, so as to further avoid the gap between the cleaning part 2 of the first cleaning assembly 021 and the cleaning part 2 of the second cleaning assembly 022 during rotation, completely avoid the occurrence of missed cleaning area, and ensure the cleaning effect of the cleaning equipment.

[0069] Meanwhile, since the arc center of the arc surface of the moving part 13 in the first cleaning assembly 021 and the arc center of the arc surface of the moving part 13 in the second cleaning assembly 022 are close to the center axis S2 of the respective main body part 12 relative to the respective arc surface, when the moving part 13 of the first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022 meet during rotation, the respective arc surface can be used for guidance, avoiding hard collision between the moving part 13 of the adjacent first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022, which can improve the fluency of rotation of the first cleaning assembly 021 and the second cleaning assembly 022, reduce the probability of damage caused by hard collision between the moving part 13 of the adjacent first cleaning assembly 021 and the moving part 13 of the second cleaning assembly 022, and improve the service life and use stability of the cleaning equipment.

[0070] Moreover, since the moving part 13 can move towards the center axis S2 of the main body part 12, when the arc surface of the moving part 13 in the first cleaning assembly 021 and the arc surface of the moving part 13 in the second cleaning assembly 022 at least contact each other, the moving part 13 in the first cleaning assembly 021 and the moving part 13 in the second cleaning assembly 022 can both move towards the center axis S2 of the respective main body part 12, which can further reduce the probability of hard collision, and further improve the service life and use stability of the cleaning equipment.
