Description

Cleaning system and cleaning base station Technical Field

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

[0002] In order to prevent the window cleaning robot from falling from a height and taking the base station connected to the window cleaning robot with it, the existing technology is to fix the base station to a fixed object through a safety rope, so that the safety rope can pull the base station to prevent the base station from being taken away.

[0003] However, in the above method, the user has to manually fasten the safety rope every time the window cleaning robot cleans the window. On the one hand, this increases the user's usage burden and leads to a poor user experience. On the other hand, the user often forgets to fasten the safety rope, thereby increasing the safety risks of the window cleaning robot.

[0004] Summary of the Invention

[0005] The purpose of this application is to provide a cleaning system and a cleaning base station, which can automatically fix the cleaning base station and improve the safety of use.

[0006] To achieve the above-mentioned objectives, the present application provides a cleaning system on the one hand, which includes at least a cleaning base station and a cleaning device; the cleaning base station includes a base, a suction cup, an on-off component and a controller, the base is connected to the cleaning device through a first connecting piece, the suction cup is connected to the base, the suction cup is used to contact with a fixed surface and surround the fixed surface to form an adsorption space, and the on-off component is connected to the suction cup; the controller is communicatively connected to the cleaning device and the on-off component, and the controller is configured to obtain the operating status of the cleaning device and, according to the operating status, control the on-off of the adsorption space and the external environment through the on-off component.

[0007] To achieve the above-mentioned purpose, the present application also provides a cleaning base station on the other hand, which includes a base, a suction cup, an on-off component and a controller; the base is used to be connected to the cleaning equipment through a first connecting piece, the suction cup is connected to the base, the suction cup is used to contact the fixed surface and surround the fixed surface to form an adsorption space, and the on-off component is connected to the suction cup; the controller is communicatively connected to the cleaning equipment and the on-off component, and the controller is configured to obtain the operating status of the cleaning equipment, and according to the operating status, control the on-off of the adsorption space and the external environment through the on-off component.

[0008] It can be seen from this that the technical solution provided by this application is that the base of the cleaning base station is fixed to the fixed surface by adsorption through a suction cup, and an on-off component is connected to the suction cup, and the on-off component is used to control the on-off of the adsorption space formed by the suction cup and the fixed surface and the external environment. The cleaning base station also includes a controller, which is communicatively connected to the cleaning equipment and the on-off component. This application uses the controller to control the on-off of the adsorption space and the external environment through the on-off component according to the operating status of the cleaning equipment. When the cleaning equipment is working, the controller can control the on-off component to automatically disconnect the adsorption space from the external environment, so that the adsorption space forms a sealed cavity, so that the cleaning base station can be automatically fixed on the fixed surface by adsorption of the suction cup under the action of external air pressure. When the cleaning equipment completes its work, the controller can control the on-off component to automatically connect the adsorption space with the external environment, so that the adsorption force of the suction cup disappears, so that the cleaning base station can move normally from the fixed surface. In other words, during the use of the cleaning equipment, the cleaning base station can be automatically fixed on the fixed surface, or automatically restored to a state where it can move normally from the fixed surface, thereby avoiding the risk of the cleaning equipment falling and taking the cleaning base station with it, and no manual operation is required by the user, thereby reducing the user's usage burden, optimizing the user experience, and solving the safety hazards that may be caused by existing users forgetting to operate the safety rope, thereby improving the safety of the cleaning system.

[0009] The cleaning base station is also fixed to the fixed surface via suction cups, leaving no space between them. This ensures that if the cleaning equipment falls, the cleaning base station remains stationary relative to the fixed surface, preventing it from moving with the cleaning equipment and potentially colliding with foreign objects, thereby extending the cleaning base station's service life.

[0018] To make the purpose, 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 accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in this application to express spatial relative positions are used to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings for the purpose of ease of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figures. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein are interpreted accordingly.

[0019] Furthermore, the terms "installed," "disposed," "provided with," "connected," "slidingly connected," "fixed," and "socketed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0020] As people's living standards improve, more and more households are turning to various cleaning devices, such as sweeping robots and window cleaning robots, to reduce labor intensity and improve their quality of life. Take window cleaning robots, for example. These robots typically work in conjunction with a base station. The robot cleans windows, and the base station is connected to the robot via a cable, providing power and allowing the robot to recharge when needed.

[0021] In order to prevent the window cleaning robot from falling from a height and taking the base station connected to the window cleaning robot with it, the existing technology is to fix the base station to a fixed object (such as a railing and a wall, etc.) through a safety rope, so as to pull the base station with the safety rope to prevent the base station from being taken away, and at the same time pull the window cleaning robot to prevent the window cleaning robot from falling directly.

[0022] However, this approach also requires users to manually fasten the safety tether each time they clean windows. This increases the user burden and leads to a poor user experience. Furthermore, users often forget to fasten the tether, increasing safety risks associated with the window-cleaning robot. Furthermore, the flexibility of the safety tether leaves some room for movement between the base station and the fixed object. If the window-cleaning robot falls, while the robot will not drag the base station with it, it will still move and collide with the fixed object, causing damage and shortening its service life.

[0023] Therefore, how to improve the structure of the cleaning system and the cleaning base station, and then automatically fix the base station and improve the safety of use, has become a problem that needs to be solved urgently in this field.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0025] Please refer to Figures 1 and 2 together. In an achievable embodiment, the present application provides a cleaning system, which may include at least a cleaning base station 100 and a cleaning device 200, and the cleaning base station 100 and the cleaning device 200 work together. The cleaning base station 100 is used to be connected to the cleaning device 200. When the cleaning device 200 is working, the cleaning base station 100 is usually placed in a safe area, and the cleaning base station 100 holds the cleaning device 200 to prevent the cleaning device 200 from falling directly from a high altitude. In addition, the cleaning base station 100 may also have the function of providing power supply to the cleaning device 200 and the function of storing the cleaning device 200 when idle, etc., which is not specifically limited in this application. The cleaning device 200 is used to clean the target surface, wherein the cleaning device 200 may be a window cleaning robot, or other high-altitude cleaning equipment, etc.

[0026] In this 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 the basic carrier of the cleaning base station 100, and the base 110 is used to support and protect other components on the cleaning base station 100. The base 110 is also connected to the cleaning device 200 through the first connecting member 300, so as to pull the cleaning device 200 through the first connecting member 300, thereby providing safety protection for the cleaning device 200. In actual application, an automatic winding device may also be provided in the base 110. When the cleaning device is working, the automatic winding device may automatically wind up the first connecting member 300 to prevent the first connecting member 300 from scattering, reduce the problem of knotting and entanglement of the first connecting member 300 during use, and improve the interactive experience. A storage space may also be provided in the base 110. When the cleaning device 200 is not working, it can be stored in the storage space to store the cleaning device 200.

[0027] The suction cup 120 is connected to the base 110 and is used to contact the fixed surface 400 and surround the fixed surface 400 to form an adsorption space 500. When the suction cup 120 contacts the fixed surface 400, the air in the adsorption space 500 is partially squeezed out, forming a low-pressure area in the adsorption space 500. The atmospheric pressure around the suction cup 120 is relatively high, which exerts an inward pressure on the suction cup 120, thereby generating an adsorption force and firmly fixing the suction cup 120 to the fixed surface 400. It should be noted that the fixed surface 400 refers to a stationary surface. In actual applications, the fixed surface 400 can be the ground, a wall, or the surface of a heavy object.

[0028] The on-off assembly 130 is connected to the suction cup 120 and is used to control the connection and disconnection of the adsorption space 500 from the external environment. When the on-off assembly 130 controls the adsorption space 500 to be disconnected from the external environment, the adsorption space 500 becomes a sealed area, and there is a pressure difference between the adsorption space 500 and the external environment, thereby firmly fixing the suction cup 120 to the fixed surface 400. When the on-off assembly 130 controls the adsorption space 500 to be connected to the external environment, the pressure of the adsorption space 500 and the external environment are consistent, the adsorption force of the suction cup 120 disappears, and the cleaning base station 100 can move normally from the fixed surface 400. In other words, when the suction cup 120 contacts the fixed surface 400, the on-off assembly 130 can control whether the suction cup 120 is adsorbed and fixed on the fixed surface 400, and thus control whether the cleaning base station 100 is adsorbed and fixed on the fixed surface 400.

[0029] In a feasible embodiment, the cleaning base station 100 may further include a controller 140. The controller 140 is in communication with the cleaning device 200 and the on-off component 130. The controller 140 may be configured to obtain the operating status of the cleaning device 200, and according to the operating status, control the on-off of the adsorption space 500 and the external environment through the on-off component 130, thereby automatically controlling whether the cleaning base station 100 is adsorbed and fixed 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 move normally from the fixed surface 400, thereby avoiding the risk of the cleaning device 200 falling and taking the cleaning base station 100 with it, and eliminating the need for manual operation by the user, thereby reducing the user's usage burden, optimizing the user experience, and solving the safety issues that may be caused by the existing user forgetting to operate the safety rope, thereby improving the safety of the cleaning system.

[0030] It's worth noting that the cleaning base station 100 is fixed to the fixed surface 400 via suction cups 120. Compared to a method where the cleaning base station 100 is directly fastened to a fixed object via a safety tether, there is no relative movement between the cleaning base station 100 and the fixed surface 400. This allows the cleaning base station 100 to remain stationary relative to the fixed surface 400 if the cleaning device 200 falls, thus preventing the cleaning base station 100 from moving with the cleaning device 200 and potentially colliding with foreign objects, thereby increasing the service life of the cleaning base station 100.

[0031] In this embodiment, the cleaning device 200 can actively send a signal containing the operating status of the cleaning device 200 to the controller 140, which then receives the signal and obtains the operating status of the cleaning device 200 from the signal. Of course, the controller 140 can also be integrated with a detector that actively detects the movement of the cleaning device 200 and thereby obtains the operating status of the cleaning device 200. In actual applications, the communication connection between the controller 140 and the cleaning device 200 and the on / off assembly 130 can be achieved through a wired connection such as a physical cable or wire, or through a wireless connection such as Wi-Fi, Bluetooth, or infrared, which is not specifically limited in this application.

[0032] In one achievable embodiment, the operating state of the cleaning device 200 may include an operating state and a non-operating state. When the operating state is the operating state, the cleaning device 200 operates on the target surface, and the on-off assembly 130 controls the suction space 500 to be disconnected from the external environment, thereby firmly fixing the suction cup 120 to the fixed surface 400, thereby preventing the cleaning device 200 from causing the cleaning base station 100 to fall. When the operating state is the non-operating state, the cleaning device 200 is not at risk of falling, and the on-off assembly 130 controls the suction space 500 to be connected to the external environment, so that the cleaning base station 100 can move normally from the fixed surface 400, making it convenient for the user to move the cleaning base station 100.

[0033] In actual applications, the working state of the cleaning device 200 can be divided according to the opening and closing of the 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, and 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 can be a power button or a state switching button, etc. The working state of the cleaning device 200 can also be divided according to whether the preset cleaning task is completed. For example, the cleaning device 200 can automatically generate a cleaning task. When the cleaning device 200 has not completed 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 can also be divided according to the start and stop of the negative pressure component. When the negative pressure component 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.

[0034] Regarding the arrangement position of the suction cup 120 on the base 110 , this application provides two feasible embodiments for reference.

[0035] Embodiment 1: As shown in FIG. 4 , the suction cup 120 may be located on a side surface of the base 110 , so that the cleaning base station 100 is fixed by adsorption to the vertical fixing surface 400 through the side surface.

[0036] Embodiment 2: As shown in FIG. 2 , the suction cup 120 may be located at the bottom of the base 110 , so that the cleaning base station 100 is fixed by adsorption to the horizontal fixing surface 400 through the bottom.

[0037] In actual application, given that when the suction cup 120 is set on the side of the base 110, the user needs to push the cleaning base station 100 to the side of the vertical fixed surface 400 after placing the cleaning base station 100, so that the suction cup 120 can contact the vertical fixed surface 400. When the suction cup 120 is set 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 the horizontal fixed surface 400, which makes the operation simpler and more convenient. And considering that the smoothness of the fixed surface 400 will directly affect the cleaning effect of the suction cup 120, and in actual application scenarios, a smooth horizontal fixed surface is more common than a smooth vertical fixed surface. Therefore, this application preferably adopts the method of setting the suction cup 120 at the bottom of the base 110, and the subsequent description will be based on this.

[0038] Regarding the specific structure of the suction cup 120, in a feasible embodiment, as shown in Figures 5 and 6, the suction cup 120 may include a supporting portion 121 and a fitting portion 122. The supporting portion 121 is connected to the base 110, and the fitting portion 122 is arranged around the supporting portion 121, and the fitting portion 122 extends outward and downward from the edge of the supporting portion 121. The upper and lower positions defined in this application are defined based on the suction cup 120 being arranged at the bottom of the base 110, wherein the position of the suction cup 120 relative to the base 110 is the lower position, and conversely, the position of the base 110 relative to the suction cup 120 is the upper position.

[0039] In practical applications, the support portion 121 and the fitting portion 122 can be integrally formed by processes such as insert injection molding and secondary injection molding. Taking the insert injection molding process as an example, during the integral molding process, a support insert can be embedded in the support portion 121 to improve the support strength of the support portion 121 and facilitate the connection between the support portion 121 and the base 110. Of course, the support portion 121 can also be formed in two parts, with the support portion 121 being made of a hard material and the fitting portion 122 being made of a material with a certain degree of flexibility and deformability such as rubber or silicone, and then they are assembled together to form the suction cup 120 structure.

[0040] Preferably, the support portion 121 should be detachably connected to the bottom of the base 110. In this way, when the suction cup 120 is damaged, the user only needs to replace the suction cup 120, reducing maintenance costs. In actual use, the top of the support portion 121 can be provided with a threaded hole 1211, and the base 110 is screwed into the threaded hole 1211 to connect the suction cup 120 to the base 110.

[0041] In this embodiment, the support portion 121 may further include a through hole 1212. One end of the through hole 1212 communicates with the adsorption space 500, while the other end communicates with the external environment. Accordingly, the on / off assembly 130 is located at the opening of the other end of the through hole 1212. The on / off assembly 130 controls the opening and closing of the other end of the through hole 1212 to connect the adsorption space 500 to the external environment.

[0042] Specifically, the on-off assembly 130 may include a valve seat 131, a valve core 132, and a driver 133. The valve seat 131 has a first open end 1311 and a second open end 1312, and the first open end 1311 is connected to the other end of the through hole 1212. The valve core 132 has a first position and a second position. When the valve core 132 is in the first position, the valve core 132 can block the second open end 1312 of the valve seat 131, thereby isolating the adsorption space 500 from the external environment. When the valve core 132 is in the second position, the valve core 132 opens the second open end 1312 of the valve seat 131, thereby connecting the adsorption space 500 to the external environment. The driving member 133 is connected to the valve core 132. Correspondingly, the controller 140 is communicated with the driving member 133 in the on-off assembly 130. The controller 140 controls the driving member 133 to provide the valve core 132 with a driving force for switching between the first position and the second position to control the on-off of the adsorption space 500 and the external environment.

[0043] Regarding the specific form of the opening and closing method of the valve core 132 with respect to the second open end 1312, in one feasible embodiment, as shown in Figures 5 to 7, the valve core 132 is rotatably disposed in the inner cavity of the valve seat 131, the valve core 132 has a guide hole 1321, and the driving member 133 is used to drive the valve core 132 to rotate to switch between the first position and the second position. When the driving member 133 drives the valve core 132 to rotate to the first position, the guide hole 1321 is disconnected from the first open end 1311 and the second open end 1312, thereby closing the second open end 1312. When the driving member 133 drives the valve core 132 to rotate to the second position, the first open end 1311 is connected to the second open end 1312 through the guide hole 1321, thereby opening the second open end 1312.

[0044] In actual application, the driving member 133 can be a motor or a rotary cylinder, etc. Taking the driving member 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 opening and closing of the valve core 132 to the second opening end 1312.

[0045] In order 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 to be too high. Therefore, in order to avoid excessively increasing the height of the cleaning base station 100 by adding the on-off component 130, in a feasible embodiment, as shown in Figures 5 to 7, the on-off component 130 may also include a pipe connector 134. The first open end 1311 is connected to the other end of the through hole 1212 through the pipe connector 134. In addition, the pipe connector 134 has a horizontal extension section 1341 extending in 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 connector 134 can change the arrangement direction of the on-off component 130 so that the on-off component 130 is arranged in the horizontal direction, thereby reducing the space occupied by the on-off component 130 in the vertical direction, thereby reducing the overall height of the cleaning base station 100.

[0046] It should be noted that the pipe connector 134 can be a single pipe. Alternatively, the pipe connector 134 can be composed of multiple pipes nested together. For example, the pipe connector can include a right-angle pipe and a straight pipe, with one end of the right-angle pipe communicating with the other end of the through hole 1212, and the other end of the right-angle pipe communicating with the first open end 1311 via the straight pipe.

[0047] The first connecting member 300 can be configured according to the specific structure of the cleaning device 200. For details, please refer to the following:

[0048] In a feasible embodiment, when the cleaning device 200 has a built-in energy storage component, the first connecting member 300 can be a safety rope such as a wire rope. The first connecting member 300 is used to pull the cleaning device 200 to prevent the cleaning device 200 from falling, thereby providing safety protection for the cleaning device 200.

[0049] In another feasible embodiment, when the cleaning device 200 uses an external power supply, the first connecting member 300 can be a cable. Accordingly, an energy storage component is provided 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, thereby powering the cleaning device 200 through the cable. Of course, the cable can also pull the cleaning device 200 to prevent the cleaning device 200 from falling, thereby providing safety protection for the cleaning device 200.

[0050] In one possible embodiment, 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 used to connect to a fixed object. In this way, when in use, the cleaning base station 100 can be fastened to the fixed object via the safety rope, and can also be attached to the fixed surface via the suction cup 120. The safety rope and the suction cup 120 thus jointly secure the base 110, thereby providing dual protection for the cleaning base station 100 and preventing the danger caused by the accidental failure of the suction cup 120.

[0051] Based on the same inventive concept, the present application also provides a cleaning base station 100, which is used to work in conjunction 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 used to connect to the cleaning device 200 through a first connector 300, the suction cup 120 is connected to the base 110, the suction cup 120 is used to contact the fixed surface 400 and surround the fixed surface 400 to form an adsorption space 500, 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 obtain the operating status of the cleaning device 200 and control the on-off of the adsorption space 500 and the external environment through the on-off assembly 130 according to the operating status.

[0052] Furthermore, the operating state of the cleaning device 200 may include an operating state and a non-operating state. When the operating state is the operating state, the on-off component 130 controls the adsorption space 500 to be disconnected from the external environment. When the operating state is the non-operating state, the on-off component 130 controls the adsorption space 500 to be connected to the external environment.

[0053] Furthermore, the suction cup 120 is located at the bottom of the base 110 .

[0054] Regarding the base 110 , the suction cup 120 , the on / off assembly 130 and the controller 140 , reference may be made to the contents in the above embodiment, which will not be described in detail here.

[0055] The following is a detailed explanation based on specific application scenarios, taking the cleaning equipment as a window cleaning robot as an example.

[0056] Application Scenario 1

[0057] When a user needs to use the window cleaning robot to clean the windows, the user first places the cleaning base station on the ground, and the suction cup adheres to the ground under the action of gravity of the base. Then, the window cleaning robot is taken out of the cleaning base station.

[0058] As the window-cleaning robot is removed, part of the first connecting member is pulled out of the cable outlet along with the window-cleaning robot. The user turns on the window-cleaning robot's power button and places it on the window. The window-cleaning robot is adsorbed onto the window by negative pressure and, driven by the window-cleaning robot's walking mechanism, cleans the window. Simultaneously, the controller of the cleaning base station detects that the window-cleaning robot is currently in the working state. The controller controls the on-off component to automatically disconnect the adsorption space from the external environment. The cleaning base station is automatically fixed to the fixed surface by the suction cup, eliminating the need for manual operation and avoiding the safety risk of the window-cleaning robot falling and taking the cleaning base station with it.

[0059] When the window cleaning robot finishes cleaning, the user turns off the power button and removes it from the window. At the same time, the controller detects that the robot is in an inactive state. It then controls the on-off component to automatically connect the suction space to the external environment, eliminating the suction force of the suction cups. The user can then move the cleaning base station normally.

[0060] It can be seen from this that the technical solution provided by this application is that the base of the cleaning base station is fixed to the fixed surface by adsorption through a suction cup, and an on-off component is connected to the suction cup, and the on-off component is used to control the on-off of the adsorption space formed by the suction cup and the fixed surface and the external environment. The cleaning base station also includes a controller, which is communicatively connected to the cleaning equipment and the on-off component. This application uses the controller to control the on-off of the adsorption space and the external environment through the on-off component according to the operating status of the cleaning equipment. When the cleaning equipment is working, the controller can control the on-off component to automatically disconnect the adsorption space from the external environment, so that the adsorption space forms a sealed cavity, so that the cleaning base station can be automatically fixed on the fixed surface by adsorption of the suction cup under the action of external air pressure. When the cleaning equipment completes its work, the controller can control the on-off component to automatically connect the adsorption space with the external environment, so that the adsorption force of the suction cup disappears, so that the cleaning base station can move normally from the fixed surface. In other words, during the use of the cleaning equipment, the cleaning base station can be automatically fixed on the fixed surface, or automatically restored to a state where it can move normally from the fixed surface, thereby avoiding the risk of the cleaning equipment falling and taking the cleaning base station with it, and no manual operation is required by the user, thereby reducing the user's usage burden, optimizing the user experience, and solving the safety issues that may be caused by existing users forgetting to operate the safety rope, thereby improving the safety of the cleaning system.

[0061] The cleaning base station is also fixed to the fixed surface via suction cups, leaving no space between them. This ensures that if the cleaning equipment falls, the cleaning base station remains stationary relative to the fixed surface, preventing it from moving with the cleaning equipment and potentially colliding with foreign objects, thereby extending the cleaning base station's service life.

[0062] Furthermore, the suction cup is set at the bottom of the base. The user only needs to place the cleaning base station on the fixed surface to make the suction cup contact the fixed surface. Then the on-off component disconnects the adsorption space from the external environment to achieve adsorption and fixation of the suction cup and the fixed surface. No user adjustment is required, and the operation is simpler and more convenient.

[0063] Furthermore, the on-off assembly is connected to the other end of the through hole through a pipe connector, and the on-off assembly is located on the horizontal extension section of the pipe connector, so that the arrangement direction of the on-off assembly is changed by the pipe connector, so that the on-off assembly is arranged in the horizontal direction, thereby reducing the space occupied by the on-off assembly in the vertical direction, and thereby reducing the overall height of the cleaning base station.

[0064] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
