Description

TECHNICAL FIELD



[0001] The present application relates to the technical field of cleaning, and in particular, to a cleaning system and a cleaning base station.

BACKGROUND ART



[0002] To prevent a window-cleaning robot from falling from a height and carrying away a base station connected thereto, the prior art secures the base station to a fixed object by a safety rope, such that the base station is held by the safety rope to avoid being carried away together with the robot.

[0003] However, in the aforesaid manner, a user has to manually fasten the safety rope every time the window-cleaning robot cleans a window. On the one hand, this increases the user's operational burden and results in a poor user experience; on the other hand, the user often forgets to fasten the safety rope, thereby increasing potential safety hazards during the operation of the window-cleaning robot.

SUMMARY



[0004] The objective of the present application is to provide a cleaning system and a cleaning base station, which can automatically fix the cleaning base station and improve usage safety.

[0005] To achieve the above objective, in one aspect, the present application provides a cleaning system, which at least includes a cleaning base station and a cleaning device; the cleaning base station includes a base, a suction cup, an on-off assembly and a controller, the base is connected to the cleaning device through a first connecting member, the suction cup is connected to the base and configured to contact a fixed surface and to define a suction space between the suction cup and the fixed surface, and the on-off assembly is connected to the suction cup; and the controller is communicatively connected to the cleaning device and the on-off assembly, and the controller is configured to acquire an operating state of the cleaning device and control communication and isolation between the suction space and an external environment through the on-off assembly according to the operating state.

[0006] To achieve the above objective, in another aspect, the present application further provides a cleaning base station, which includes a base, a suction cup, an on-off assembly and a controller; the base is configured for being connected to a cleaning device through a first connecting member, the suction cup is connected to the base and configured to contact a fixed surface and define a suction space between the suction cup and the fixed surface, and the on-off assembly is connected to the suction cup; and the controller is communicatively connected to the cleaning device and the on-off assembly, and the controller is configured to acquire an operating state of the cleaning device and control communication and isolation of the suction space and an external environment through the on-off assembly according to the operating state.

[0007] It can be seen that, in the technical solution provided by the present application, the base of the cleaning base station is adsorptively fixed to the fixed surface by the suction cup, the on-off assembly is connected to the suction cup and configured to control communication and isolation of the suction space formed by the suction cup and the fixed surface in a surrounding manner with an external environment. The cleaning base station further includes a controller which is communicatively connected to the cleaning device and the on-off assembly. The present application utilizes the controller to control the communication and isolation of the suction space with the external environment through the on-off assembly according to the operating state of the cleaning device. When the cleaning device is in operation, the controller can control the on-off assembly to automatically disconnect the suction space from the external environment, so that the suction space forms a sealed cavity, and thus the cleaning base station can be adsorptively fixed to the fixed surface by the suction cup under an action of external atmospheric pressure to realize automatic fixation. When the cleaning device finishes operation, the controller can control the on-off assembly to automatically connect the suction space to the external environment, so that the adsorption force of the suction cup disappears, and thus the cleaning base station can be moved from the fixed surface normally. In other words, during the use of the cleaning device, the cleaning base station can be automatically fixed to the fixed surface or automatically restored to a state where it can be normally moved from the fixed surface, which not only avoids the risk that the cleaning base station is carried away together with the falling cleaning device, but also eliminates the need for manual operation by the user, reduces the user's operational burden and optimizes the user experience. In addition, it solves the potential safety hazards that may be caused by the user's forgetting to fasten the safety rope in the prior art, and improves the usage safety of the cleaning system.

[0008] Meanwhile, the cleaning base station is adsorptively fixed to the fixed surface by the suction cup, with no relative movable space between the cleaning base station and the fixed surface. In this way, when the cleaning device falls, the cleaning base station always remains stationary relative to the fixed surface, thereby preventing the cleaning base station from moving with the cleaning device and being damaged by collision with foreign objects, and further improving the service life of the cleaning base station.

DETAILED DESCRIPTION OF THE EMBODIMENTS



[0010] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings. Terms indicating relative spatial positions used in this application, such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" and the like, are configured for the convenience of describing the relationship between one unit or feature and another unit or feature as shown in the drawings. The terms indicating relative spatial positions are intended to include different orientations of the device during use or operation other than the orientation shown in the drawings. For example, if the device in the drawings is turned over, a unit described as being "below" or "beneath" another unit or feature will be located "above" the other unit or feature. Therefore, the exemplary term "below" may encompass both upper and lower orientations. The device may be oriented in other ways (rotated by 90 degrees or other orientations), and the spatially relative descriptors used herein shall be interpreted accordingly.

[0011] In addition, the terms "mount", "arrange", "be provided with", "connect", "slidingly connect", "fix", "socket connect" shall be understood in a broad sense. For example, "connect" may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be a direct connection, an indirect connection through an intermediate medium, or internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0012] With the improvement of people's living standards, more and more families begin to use various cleaning devices, such as sweeping robots, window-cleaning robots and other devices, to reduce labor intensity and improve the quality of life. Taking a window-cleaning robot as an example, the window-cleaning robot usually works in coordination with a base station, the window-cleaning robot is used to clean the surface of a window, and the base station is connected to the window-cleaning robot through a cable to supply power to the window-cleaning robot and allow the window-cleaning robot to be charged when needed.

[0013] To prevent a window-cleaning robot from falling from a height and carrying away a base station connected thereto, the prior art secures the base station to a fixed object (such as a railing, a wall, etc.) by a safety rope, so that the base station is held by the safety rope to avoid being carried away together with the robot, and the window-cleaning robot is also held to prevent it from falling directly.

[0014] However, the aforesaid manner also results in that a user has to manually fasten the safety rope every time a window is cleaned. On the one hand, this increases the user's operational burden and leads to a poor user experience; on the other hand, the user often forgets to fasten the safety rope, thereby increasing potential safety hazards during the operation of the window-cleaning robot. In addition, the flexibility of the safety rope results in a certain movable space between the base station and the fixed object. When the window-cleaning robot falls, although the window-cleaning robot will not drive the base station to fall together, it still causes the base station to move and be damaged by collision with the fixed object, affecting the service life of the base station.

[0015] Therefore, how to improve the structures of the cleaning system and the cleaning base station to further automatically fix the base station and improve usage safety has become an urgent problem to be solved in the art.

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those skilled in the art without creative work based on the embodiments of this application shall fall within the protection scope of the present application.

[0017] Please refer to FIG. 1 and FIG. 2 together. In an achievable implementation manner, the present application provides a cleaning system, which at least includes a cleaning base station 100 and a cleaning device 200 that work in coordination. The cleaning base station 100 is configured for being connected to the cleaning device 200. When the cleaning device 200 is in operation, the cleaning base station 100 is usually placed in a safe region, and the cleaning device 200 is held by the cleaning base station 100 to prevent the cleaning device 200 from falling directly from a height. In addition, the cleaning base station 100 may also have functions such as supplying power to the cleaning device 200 and storing the cleaning device when it is idle, which are not specifically limited in the present application. The cleaning device 200 is configured for cleaning a target surface, wherein the cleaning device 200 may be a window-cleaning robot, or other cleaning devices for high-altitude operations, etc.

[0018] In the present embodiment, the cleaning base station 100 may include a base 110, a suction cup 120 and an on-off assembly 130. The base 110 serves as a basic carrier of the cleaning base station 100, and is configured for supporting and protecting other parts on the cleaning base station 100. The base 110 is also connected to the cleaning device 200 through a first connecting member 300, so as to hold the cleaning device 200 via the first connecting member 300 and thus play a safety protection role for the cleaning device 200. In practical application, an automatic winding device may also be disposed in the base 110. When the cleaning device is in operation, the automatic winding device can automatically wind the first connecting member 300, avoid the scattering of the first connecting member 300, reduce the problems of knotting and winding of the first connecting member 300 during use, and improve the interactive experience. A storage space may also be disposed in the base 110, and the cleaning device 200 can be stored in the storage space when it is not in operation for accommodating the cleaning device 200.

[0019] The suction cup 120 is connected to the base 110, and is configured to contact a fixed surface 400 and to define a suction space 500 between the suction cup 120 and the fixed surface 400. When the suction cup 120 is in contact with the fixed surface 400, part of the air in the suction space 500 can be extruded out, so that a low-pressure region is formed in the suction space 500. The atmospheric pressure around the suction cup 120 is relatively high, which can exert an inward pressure on the suction cup 120, so that the suction cup 120 generates an adsorption force and is firmly fixed on the fixed surface 400. It should be noted that the fixed surface 400 refers to a stationary surface, and in practical application, the fixed surface 400 may be a ground surface, a wall surface, or the surface of a heavy object, etc.

[0020] The on-off assembly 130 is connected to the suction cup 120, and is configured for controlling the communication and isolation between the suction space 500 and the external environment. When the on-off assembly 130 controls the isolation between the suction space 500 and the external environment, the suction space 500 is a sealed region, and there is a pressure difference between the suction space 500 and the external environment, thereby firmly fixing the suction cup 120 on the fixed surface 400. When the on-off assembly 130 controls the communication between the suction space 500 and the external environment, the pressure of the suction space 500 is consistent with that of the external environment, the adsorption force of the suction cup 120 disappears, and thus the cleaning base station 100 can be moved from the fixed surface 400 normally. In other words, when the suction cup 120 is in contact with the fixed surface 400, the on-off assembly 130 can control whether the suction cup 120 is fixedly adsorbed on the fixed surface 400, and further control whether the cleaning base station 100 is fixedly adsorbed on the fixed surface 400.

[0021] In an achievable implementation manner, the cleaning base station 100 may further include a controller 140. The controller 140 is communicatively connected to the cleaning device 200 and the on-off assembly 130. The controller 140 may be configured to acquire an operation state of the cleaning device 200 and control the communication and isolation between the suction space 500 and the external environment through the on-off assembly 130 according to the operation state, so as to automatically control whether the cleaning base station 100 is fixedly adsorbed on the fixed surface 400. In other words, during the use of the cleaning device 200, the cleaning base station 100 can be automatically fixed on the fixed surface 400 or automatically restored to a state where it can be moved normally from the fixed surface 400, which not only avoids the risk that the cleaning base station 100 is carried away together when the cleaning device 200 falls, but also eliminates the need for manual operation by the user, reduces the user's operational burden, optimizes the user experience, solves the safety problems that may be caused by the user's forgetting to operate the safety rope in the prior art, and improves the usage safety of the cleaning system.

[0022] It is worth mentioning that the cleaning base station 100 is fixedly adsorbed on the fixed surface 400 through the suction cup 120. Compared with the way that the cleaning base station 100 is directly fastened to a fixed object by a safety rope, there is no relative movement space between the cleaning base station 100 and the fixed surface 400. In this way, when the cleaning device 200 falls, the cleaning base station 100 always remains stationary relative to the fixed surface 400, thereby preventing the cleaning base station 100 from moving with the cleaning device 200 and being damaged by collision with foreign objects, and further improving the service life of the cleaning base station 100.

[0023] In the present embodiment, the cleaning device 200 may actively send a signal containing its own operation state to the controller 140, and the controller 140 receives the signal and acquires the operation state of the cleaning device 200 from the signal. Certainly, the controller 140 may also be integrated with a detector, which actively detects the actions of the cleaning device 200 to acquire the operation state of the cleaning device 200. In practical application, the communication connection between the controller 140 and the cleaning device 200, as well as the on-off assembly 130, may adopt a wired connection mode such as a physical cable or wire, or a wireless connection mode such as Wi-Fi, Bluetooth, infrared, etc., which is not specifically limited in the present application.

[0024] In an achievable implementation manner, the operation state of the cleaning device 200 may include a working state and a non-working state. When the operation state is the working state, the cleaning device 200 works on the target surface, and the on-off assembly 130 controls the isolation between the suction space 500 and the external environment, so as to firmly fix the suction cup 120 on the fixed surface 400, thereby preventing the cleaning device 200 from driving the cleaning base station 100 to fall together. When the operation state is the non-working state, the cleaning device 200 has no falling risk, and the on-off assembly 130 controls the communication between the suction space 500 and the external environment, so that the cleaning base station 100 can be moved from the fixed surface 400 normally, facilitating the user to move the cleaning base station 100.

[0025] In practical application, the working state of the cleaning device 200 may be divided according to the on-off of a preset button on the cleaning device 200. For example, when the preset button on the cleaning device 200 is turned on, it indicates that the cleaning device is in the working state; when the preset button on the cleaning device 200 is turned off, it indicates that the cleaning device is in the non-working state, wherein the preset button may be a power button or a state switch button, etc. The working state of the cleaning device 200 may also be divided according to whether a preset cleaning task is completed. For example, the cleaning device 200 may automatically generate a cleaning task; when the cleaning device 200 does not complete the cleaning task, it indicates that the cleaning device is in the working state; when the cleaning device 200 completes the cleaning task, it indicates that the cleaning device is in the non-working state. For a window-cleaning robot, the working state of the cleaning device 200 may also be divided according to the start and stop of a negative pressure part. When the negative pressure part is turned on, it indicates that the cleaning device is in the working state; when the negative pressure component is turned off, it indicates that the cleaning device is in the non-working state.

[0026] Regarding the arrangement position of the suction cup 120 on the base 110, the present application provides two achievable embodiments for reference.

[0027] Embodiment 1: As shown in FIG. 4, the above suction cup 120 may be located on the side surface of the base 110, so that the cleaning base station 100 is fixedly adsorbed to a vertical fixed surface 400 through the side surface.

[0028] Embodiment 2: As shown in FIG. 2, the above suction cup 120 may be located at the bottom of the base 110, so that the cleaning base station 100 is fixedly adsorbed to a horizontal fixed surface 400 through the bottom.

[0029] In practical application, considering that when the suction cup 120 is disposed on the side surface of the base 110, the user still needs to push the cleaning base station 100 to the side of the vertical fixed surface 400 after placing the cleaning base station 100 to make the suction cup 120 contact with the vertical fixed surface 400. While when the suction cup 120 is disposed at the bottom of the base 110, the user only needs to place the cleaning base station 100 on the horizontal fixed surface 400 to make the suction cup 120 contact with the horizontal fixed surface 400, and the operation is simpler and more convenient. In addition, considering that the smoothness of the fixed surface 400 will directly affect the adsorption effect of the suction cup 120, and in practical application scenarios, smooth horizontal fixed surfaces are more common than smooth vertical fixed surfaces. Therefore, the present application preferably adopts disposing the suction cup 120 at the bottom of the base 110, and the following description will be based on this.

[0030] Regarding the specific structure of the suction cup 120, in an achievable implementation manner, as shown in FIG. 5 and FIG. 6, the suction cup 120 may include a supporting part 121 and a fitting part 122. The supporting part 121 is connected to the base 110, and the fitting part 122 is disposed around the supporting part 121 and extends outwards and downwards from the edge of the supporting part 121. The upper and lower orientations defined in the present application are based on the suction cup 120 being disposed at the bottom of the base 110, wherein the orientation of the suction cup 120 relative to the base 110 is the lower orientation; on the contrary, the orientation of the base 110 relative to the suction cup 120 is the upper orientation.

[0031] In practical application, the supporting part 121 and the fitting part 122 may be integrally formed by processes such as insert injection molding, two-shot injection molding, etc. Taking the insert injection molding process for the supporting part 121 and the fitting part 122 as an example, a supporting insert may be embedded in the supporting part 121 during the integral forming process to improve the supporting strength of the supporting part 121, so as to facilitate the connection between the supporting part 121 and the base 110. Certainly, the supporting part 121 may also be formed separately, the supporting part 121 is made of a hard material, and the fitting part 122 is made of a material with certain flexibility and deformability, such as rubber or silica gel, and then they are assembled with each other to form the structure of the suction cup 120.

[0032] Preferably, the supporting part 121 should be detachably connected to the bottom of the base 110, so that when the suction cup 120 is damaged, the user only needs to replace the suction cup 120, reducing the maintenance cost. In practical application, a threaded hole 1211 may be opened at the top of the supporting part 121, and the base 110 is in threaded connection with the threaded hole 1211 through a screw to connect the suction cup 120 to the base 110.

[0033] In the present embodiment, a through hole 1212 may also be opened on the supporting part 121, one end of the through hole 1212 communicates with the suction space 500, and the other end of the through hole 1212 communicates with the external environment. Correspondingly, the on-off assembly 130 is located at the opening of the other end of the through hole 1212, and the on-off assembly 130 controls the communication and isolation between the suction space 500 and the external environment by controlling the on-off of the other end of the through hole 1212.

[0034] Specifically, the above on-off assembly 130 may include a valve seat 131, a valve core 132 and a driving part 133. The valve seat 131 is provided with a first open end 1311 and a second open end 1312, and the first open end 1311 communicates with the other end of the through hole 1212. The valve core 132 can be positioned at a first position or a second position. When the valve core 132 is at the first position, the second open end 1312 of the valve seat 131 is closed, so that the suction space 500 is isolated from the external environment. When the valve core 132 is at the second position, the second open end 1312 of the valve seat 131 is open, so that the suction space 500 communicates with the external environment. The driving part 133 is connected to the valve core 132. Correspondingly, the controller 140 is communicatively connected to the driving part 133 in the on-off assembly 130, and the controller 140 controls the driving part 133 to provide a driving force for the valve core 132 to switch between the first position and the second position, so as to control the communication and isolation between the suction space 500 and the external environment.

[0035] Regarding the specific form of the on-off mode of the valve core 132 for the second open end 1312, in an achievable implementation manner, as shown in FIG. 5 to FIG. 7, the valve core 132 is rotatably disposed in an inner cavity of the valve seat 131, the valve core 132 is provided with a via hole 1321, and the driving part 133 is configured for driving the valve core 132 to rotate to switch between the first position and the second position. When the driving part 133 drives the valve core 132 to rotate to the first position, the via hole 1321 is not communicated with the first open end 1311 and the second open end 1312 to close the second open end 1312. When the driving part 133 drives the valve core 132 to rotate to the second position, the first open end 1311 communicates with the second open end 1312 through the via hole 1321 to open the second open end 1312.

[0036] In practical application, the driving part 133 may adopt a motor, or a rotary cylinder, etc. Taking the motor as the driving part 133 as an example, the output shaft of the motor is connected to the valve core 132, so that the motor drives the valve core 132 to rotate to control the on-off of the second open end 1312 by the valve core 132.

[0037] To ensure the portability and storability of the cleaning base station 100, the height of the cleaning base station 100 should generally not be designed too high. Therefore, to avoid excessively increasing the height of the cleaning base station 100 due to the addition of the on-off assembly 130, in an achievable implementation manner, as shown in FIG. 5 to FIG. 7, the on-off assembly 130 may further include a pipe connecting member 134. The first open end 1311 communicates with the other end of the through hole 1212 through the pipe connecting member 134. In addition, the pipe connecting member 134 is provided with a horizontal extension section 1341 extending along the radial direction of the through hole 1212, and the valve seat 131 is connected to the horizontal extension section 1341. In this way, the pipe connecting member 134 can change the arrangement direction of the on-off assembly 130, so that the on-off assembly 130 is disposed in the horizontal direction, thereby reducing the space occupied by the on-off assembly 130 in the vertical direction, and further reducing the overall height of the cleaning base station 100.

[0038] It should be noted that the pipe connecting member 134 may be a single pipe fitting. Alternatively, the pipe connecting member 134 may also be formed by nesting a plurality of pipe fittings. For example, the pipe connecting member may include a right-angle pipe fitting and a straight pipe, one end of the right-angle pipe fitting communicates with the other end of the through hole 1212, and the other end of the right-angle pipe fitting communicates with the first open end 1311 through the straight pipe.

[0039] The above first connecting member 300 may be set correspondingly according to the specific structure of the cleaning device 200, and the specific content may refer to the following:

[0040] In an achievable implementation manner, when the cleaning device 200 is built with an energy storage component, the first connecting member 300 may be a safety rope such as a cord, which is configured for holding the cleaning device 200 to prevent it from falling and plays a safety protection role for the cleaning device 200.

[0041] In another achievable implementation manner, when the cleaning device 200 adopts an external power supply, the first connecting member 300 may be a cable. Correspondingly, an energy storage component is disposed in the cleaning base station 100, one end of the cable is connected to the energy storage component, and the other end of the cable is connected to the cleaning device 200, so as to supply power to the cleaning device 200 through the cable. Certainly, the cable can also hold the cleaning device 200 to prevent it from falling and play a safety protection role for the cleaning device 200.

[0042] In an achievable implementation manner, the cleaning system may further include a safety rope (not shown). One end of the safety rope is connected to the base 110, and the other end of the safety rope is configured to be connected to a fixed object. In this way, during use, the cleaning base station 100 can be fastened to the fixed object by the safety rope on the one hand, and adsorbed on the fixed surface by the suction cup 120 on the other hand, so that the base 110 is fixed by the safety rope and the suction cup 120 together, thereby playing a dual protection role for the cleaning base station 100 and avoiding dangers caused by accidental failure of the suction cup 120.

[0043] Based on the same inventive concept, the present application also provides a cleaning base station 100, which is configured for working in coordination with a cleaning device 200. Specifically, the cleaning base station 100 may include a base 110, a suction cup 120, an on-off assembly 130 and a controller 140. The base 110 is configured to be connected to the cleaning device 200 through a first connecting member 300, the suction cup 120 is connected to the base 110, the suction cup 120 is configured to contact a fixed surface 400 and to define a suction space 500 between the suction cup 120 and the fixed surface 400, and the on-off assembly 130 is connected to the suction cup 120. The controller 140 is communicatively connected to the cleaning device 200 and the on-off assembly 130, and the controller 140 is configured to acquire the operation state of the cleaning device 200 and control the communication and isolation between the suction space 500 and the external environment through the on-off assembly 130 according to the operation state.

[0044] Further, the operation state of the cleaning device 200 may include a working state and a non-working state. When the operation state is the working state, the on-off assembly 130 controls the isolation between the suction space 500 and the external environment. When the operation state is the non-working state, the on-off assembly 130 controls the communication between the suction space 500 and the external environment.

[0045] Further, the suction cup 120 is located at the bottom of the base 110.

[0046] For the base 110, the suction cup 120, the on-off assembly 130 and the controller 140, reference may be made to the content in the above embodiments, which will not be repeated here.

[0047] The following is a detailed description in combination with a specific application scenario, taking the cleaning device as a window-cleaning robot as an example.

Application Scenario 1



[0048] When a user needs to use a window-cleaning robot to clean windows, the user first places the cleaning base station on the ground, and the suction cup is attached to the ground under the gravity of the base. Then, the window-cleaning robot is taken out from the cleaning base station.

[0049] With the taking out of the window-cleaning robot, part of the first connecting member is pulled out from the wire outlet together with the window-cleaning robot. The user turns on the power button of the window-cleaning robot and places the window-cleaning robot on the window. The window-cleaning robot is adsorbed on the window through negative pressure and cleans the window under the drive of the walking mechanism of the window-cleaning robot. At the same time, the controller of the cleaning base station acquires that the state of the window-cleaning robot is the working state at this time, and the controller controls the on-off assembly to automatically disconnect the suction space from the external environment. The cleaning base station is adsorbed on the fixed surface under the action of the suction cup to realize automatic fixation without manual operation, avoiding the safety risk that the cleaning base station is carried away together when the window-cleaning robot falls.

[0050] When the window-cleaning robot finishes the window cleaning work, the user turns off the power button of the window-cleaning robot and takes it off the window. At the same time, the controller acquires that the state of the window-cleaning robot is the non-working state at this time, and the controller controls the on-off assembly to automatically connect the suction space to the external environment, so that the adsorption force of the suction cup disappears, and the user can move the cleaning base station normally.

[0051] It can be seen that, in the technical solution provided by the present application, the base of the cleaning base station is fixedly adsorbed to the fixed surface through the suction cup, the on-off assembly is connected to the suction cup, and the on-off assembly is used to control the communication and isolation between the suction space formed by the suction cup and the fixed surface and the external environment. The cleaning base station further includes a controller, which is communicatively connected to the cleaning device and the on-off assembly. The present application utilizes the controller to control the communication and isolation between the suction space and the external environment through the on-off assembly according to the operation state of the cleaning device. When the cleaning device is in operation, the controller can control the on-off assembly to automatically disconnect the suction space from the external environment, so that the suction space forms a sealed cavity, and thus the cleaning base station can be fixedly adsorbed on the fixed surface through the suction cup under the action of external atmospheric pressure to realize automatic fixation. When the cleaning device finishes working, the controller can control the on-off assembly to automatically connect the suction space to the external environment, so that the adsorption force of the suction cup disappears, and thus the cleaning base station can be moved from the fixed surface normally. In other words, during the use of the cleaning device, the cleaning base station can be automatically fixed on the fixed surface or automatically restored to a state where it can be moved normally from the fixed surface, which not only avoids the risk that the cleaning base station is carried away together when the cleaning device falls, but also eliminates the need for manual operation by the user, reduces the user's operational burden, optimizes the user experience, solves the safety problems that may be caused by the user's forgetting to operate the safety rope in the prior art, and improves the usage safety of the cleaning system.

[0052] Meanwhile, the cleaning base station is fixedly adsorbed on the fixed surface through the suction cup, and there is no relative movement space between the cleaning base station and the fixed surface. In this way, when the cleaning device falls, the cleaning base station always remains stationary relative to the fixed surface, thereby preventing the cleaning base station from moving with the cleaning device and being damaged by collision with foreign objects, and further improving the service life of the cleaning base station.

[0053] Further, the suction cup is disposed at the bottom of the base, and the user only needs to place the cleaning base station on the fixed surface to make the suction cup contact with the fixed surface, and then the on-off assembly disconnects the suction space from the external environment to realize the fixed adsorption between the suction cup and the fixed surface without adjustment and operation by the user, making the operation simpler and more convenient.

[0054] Furthermore, the on-off assembly communicates with the other end of the through hole through the pipe connecting member, and the on-off assembly is located on the horizontal extension section of the pipe connecting member, so that the pipe connecting member changes the arrangement direction of the on-off assembly, making the on-off assembly arranged in the horizontal direction, thereby reducing the space occupied by the on-off assembly in the vertical direction, and further reducing the overall height of the cleaning base station.

[0055] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
