Description

Technical Field

[0001] This application relates to the field of intelligent cleaning technology, specifically to a window cleaning robot, a base station, a composite pipeline, and a window cleaning system. Background Technology

[0002] In related technologies, a window cleaning robot is a device that can move on a window and clean the surface of the window to be cleaned during the movement.

[0003] Window cleaning robots are typically equipped with suction cups, wheels, nozzles, and cloths. The robot attaches to the surface to be cleaned using the suction cups and moves across it using the wheels. Simultaneously, the nozzles spray liquid onto the surface, which is then wiped clean with the cloth.

[0004] However, the cleaning cloth's absorption capacity for cleaning solution is limited. As cleaning continues, the cloth's absorbency gradually weakens, and it may even become unable to absorb any cleaning solution at all. This causes the cleaning solution to flow around the suction cup or enter the suction cup's adsorption chamber, making it difficult for the window cleaning robot to maintain its adherence to the surface to be cleaned. This increases the risk of the window cleaning robot falling off the surface. Therefore, the cloth needs to be replaced frequently to ensure the window cleaning robot can work continuously, resulting in low work efficiency and a poor user experience.

[0005] Moreover, due to the limited liquid absorption capacity of the rag, the spray nozzle can only use intermittent liquid spraying to ensure that the window cleaning robot can work for a long time. However, this cleaning method has poor cleaning effect and is difficult to deal with dirty surfaces. It can only clean the surface multiple times, which also leads to low work efficiency and poor user experience of the window cleaning robot.

[0006] In summary, window cleaning robots in related technologies suffer from poor cleaning performance and low work efficiency. Summary of the Invention

[0007] This application proposes a window cleaning robot with excellent cleaning effect and high work efficiency.

[0008] In addition, other aspects of this application are also intended to solve or alleviate other technical problems existing in the prior art.

[0009] This application provides a window cleaning robot, a base station, a composite pipeline, and a window cleaning system. Specifically, according to a first aspect of this application, a window cleaning robot includes:

[0010] The host unit is capable of adhering to the surface to be cleaned and moving on the surface to be cleaned;

[0011] An adsorption element, wherein the adsorption element is disposed on the main unit, and the main unit is capable of adhering to the surface to be cleaned via the adsorption element; and

[0012] The cleaning component includes a spraying component and a suction component, both disposed on the main unit. The spraying component is capable of spraying liquid onto the surface to be cleaned, and the suction component is capable of absorbing liquid on the surface to be cleaned by negative pressure.

[0013] In one of the linear movement directions of the window cleaning robot, at least one of the liquid-absorbing components is located between the liquid-spraying component and the suction component;

[0014] The window cleaning robot also includes a walking device installed on the main unit, which enables the main unit to move on the surface to be cleaned.

[0015] First, the main unit can be attached to the surface to be cleaned by the suction device and can move on the surface to be cleaned by the walking device, so that the cleaning components follow the main unit and clean different parts of the surface to be cleaned.

[0016] The cleaning components include a spraying component and a suction component, both mounted on the main unit. The spraying component can spray liquid (which can be water or a cleaning solution used for cleaning glass surfaces) onto the surface to be cleaned. The suction component can absorb the liquid on the surface to be cleaned by using negative pressure. In one of the linear movement directions of the window cleaning robot, the suction component is located between the spraying component and the suction component.

[0017] On one hand, as the window cleaning robot moves along one of its linear directions and performs window cleaning, the spraying component sprays liquid onto the surface to be cleaned. As the robot moves, it moves the suction component to the spraying position of the cleaning liquid. The suction component absorbs the cleaning liquid, ensuring that it is absorbed before it comes into contact with the suction component. This prevents the cleaning liquid from entering the suction chamber of the suction component and ensures that the suction component does not reduce or lose its suction capacity, thus preventing the window cleaning robot from falling off the surface. Moreover, the suction component design means that the cleaning liquid does not need to be completely absorbed by the cloth, extending the single working time of the cloth and consequently the single working time of the window cleaning robot. This avoids the need for users to frequently change cloths, resulting in a better user experience. On the other hand, the suction component not only absorbs cleaning fluid but also utilizes its negative pressure to absorb other liquids, dust, and debris remaining on the surface to be cleaned, further improving the window cleaning effect of the window cleaning robot. For example, the suction component can also absorb rainwater, dirty water, dust, and debris remaining on the surface to be cleaned, enhancing the cleaning efficiency of the window cleaning robot. Furthermore, when the suction component absorbs cleaning fluid, the fluid flows along the walls of the suction chamber, cleaning the chamber walls and achieving self-cleaning of the suction component, significantly improving the utilization rate of the cleaning fluid.

[0018] On the other hand, in related technologies, due to the limited liquid absorption capacity of the wiping cloth, the spraying component can only spray liquid intermittently to ensure that the window cleaning robot can work for a long time. However, this cleaning method is difficult to deal with heavily soiled surfaces, and the surface to be cleaned must be cleaned multiple times to meet the cleaning requirements. That is, the window cleaning robots in related technologies have poor cleaning effect and low cleaning efficiency when dealing with heavily soiled surfaces. The window cleaning robot proposed in this application can use the spraying component and the suction component to work together when dealing with heavily soiled surfaces. The spraying component can continuously spray liquid to continuously rinse and spray the surface to be cleaned, effectively improving the cleaning effect of the window cleaning robot. At the same time, the suction component can effectively absorb excess cleaning liquid instead of having it all absorbed by the wiping cloth. Therefore, it is not necessary to frequently change the wiping cloth. In this way, the window cleaning robot can improve both its cleaning effect and its working efficiency.

[0019] In summary, by incorporating a suction component on the main unit to absorb the cleaning fluid sprayed by the sprayer, the cleaning fluid does not need to be completely absorbed by the cloth, extending the cloth's lifespan and reducing the need for frequent cloth replacements. This allows the window cleaning robot to operate for extended periods, improving its efficiency and enhancing the user experience. Furthermore, the suction component, by absorbing the cleaning fluid, also self-cleans itself, ensuring efficient use of the fluid. It also effectively absorbs floating dust and debris, further improving the cleaning effect. Moreover, positioning the suction component between the sprayer and the suction component along one of the robot's linear movement directions ensures that the cleaning fluid is absorbed before contacting the suction component, guaranteeing its adhesion and preventing the robot from easily detaching from the surface being cleaned, thus ensuring its safety. Furthermore, the spraying and suction components can work together. When dealing with heavily soiled surfaces, the spraying component can continuously spray liquid to achieve the effect of rinsing and spraying the surface to be cleaned. Compared with related technologies that can only spray liquid intermittently, this eliminates the need for multiple cleaning operations to complete the cleaning. At the same time, the suction component can effectively absorb the liquid, thus improving both the cleaning effect and work efficiency.

[0020] According to a second aspect of this application, a window cleaning robot includes:

[0021] The host unit is capable of adhering to the surface to be cleaned and moving on the surface to be cleaned;

[0022] An adsorption element, wherein the adsorption element is disposed on the main unit, and the main unit is capable of adhering to the surface to be cleaned via the adsorption element; and

[0023] The cleaning component includes a spraying component and a suction component, both disposed on the main unit. The spraying component is capable of spraying liquid onto the surface to be cleaned, and the suction component is capable of absorbing liquid on the surface to be cleaned by negative pressure.

[0024] In one of the linear movement directions of the window cleaning robot, at least one of the liquid-absorbing components is located between the liquid-spraying component and the suction component, and the distance between the at least one liquid-absorbing component and the liquid-spraying component is greater than or equal to 1 cm and less than or equal to 6 cm;

[0025] The window cleaning robot also includes a walking device installed on the main unit, which enables the main unit to move on the surface to be cleaned.

[0026] One type of window cleaning robot includes: a main unit capable of adhering to and moving on a surface to be cleaned; an adsorption element disposed on the main unit, allowing the main unit to attach to the surface to be cleaned via the adsorption element; and a cleaning component comprising a spraying element and a suction element both disposed on the main unit, wherein the spraying element sprays liquid onto the surface to be cleaned, and the suction element absorbs liquid from the surface to be cleaned by negative pressure; in one of the linear movement directions of the window cleaning robot, at least one of the suction elements is located between the spraying element and the adsorption element; the window cleaning robot also includes a walking device disposed on the main unit, allowing the main unit to move on the surface to be cleaned via the walking device; these technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0027] To ensure optimal cleaning performance when the suction and spray components work together, the distance between them should be greater than or equal to 1 cm and less than or equal to 6 cm.

[0028] If the distance between the suction component and the spray component is less than 1 cm, on the one hand, if the distance between the suction component and the spray component is too close, most of the cleaning liquid sprayed by the spray component will be quickly absorbed by the suction component, so that the cleaning liquid cannot fully combine with the dirt on the surface to be cleaned, resulting in poor cleaning effect; on the other hand, if the distance between the suction component and the spray component is too close, when the suction component and the spray component work together, the vibration generated by the two components will easily affect each other, which will reduce the installation stability of the two components on the host and the working stability when working together, making it difficult for the suction component and the spray component to perform their due work performance, resulting in poor cleaning ability of the window cleaning robot.

[0029] It should be noted that the water absorption rate of a window cleaning robot refers to the ratio between the amount of water absorbed by the suction component and the amount of water sprayed by the spraying component during the robot's operation, usually expressed as a percentage. This ratio reflects the efficiency of the suction component in absorbing the water sprayed by the spraying component, thus reflecting the cleaning effect of the window cleaning robot. The higher the water absorption rate, the better the cleaning effect of the window cleaning robot on the surface to be cleaned.

[0030] Reference Figure 9 , Figure 9The diagram shows the relationship between the water absorption rate of the window cleaning robot and the distance between the suction and spray components. It can be seen that as the distance between the suction and spray components increases from 1 cm to 6 cm, the water absorption rate of the window cleaning robot gradually decreases. When the distance between the suction and spray components is 6 cm, the water absorption rate of the window cleaning robot is 80%, which is the minimum acceptable water absorption rate for users. However, when the distance between the suction and spray components is greater than 6 cm, the water absorption rate of the window cleaning robot will be lower than 80%, which is unacceptable to users because the distance between the suction and spray components is too large, causing the suction component to... As the robot moves, it reaches the cleaning fluid location more slowly and cannot absorb the fluid in time. The unabsorbed fluid flows downwards due to gravity, preventing the robot from ensuring that most of the fluid remains in the designated cleaning area for cleaning. This results in poor cleaning performance and underutilization of the cleaning fluid. Furthermore, because some of the fluid flows downwards, the robot cannot clean it in time, leading to water stains that require secondary cleaning, thus reducing the robot's overall cleaning efficiency.

[0031] Therefore, setting the distance between the spraying and suction components to be greater than or equal to 1 cm and less than or equal to 6 cm is a reasonable range. Firstly, this ensures the distance between the spraying and suction components is not too close, allowing most of the cleaning fluid sprayed to remain on the designated cleaning area. This provides sufficient time for the cleaning fluid and dirt to mix before being absorbed by the suction component, resulting in optimal cleaning performance for the window cleaning robot. Secondly, it ensures that the suction and spraying components do not interfere with each other when working together, allowing both to perform at their optimal levels and ensuring... The window cleaning robot boasts excellent cleaning performance; moreover, the distance between the suction and spray components is not too far, allowing the suction component to reach the cleaning fluid location more quickly as the robot moves forward, absorbing the cleaning fluid promptly. The robot's water absorption rate can be maintained at 80% or higher, ensuring excellent cleaning results. It prevents some cleaning fluid from flowing downwards, eliminating the need for secondary cleaning. Furthermore, it ensures that all or even most of the cleaning fluid remains on the designated cleaning area for the robot to wipe, effectively utilizing the cleaning fluid.

[0032] According to a third aspect of this application, this application provides a window cleaning robot, comprising:

[0033] The host unit is capable of adhering to and moving on the surface to be cleaned.

[0034] An adsorption element, wherein the adsorption element is disposed on the main unit, and the main unit is capable of adhering to the surface to be cleaned via the adsorption element; and

[0035] The cleaning component includes a spraying component and a suction component, both disposed on the main unit. The spraying component is capable of spraying liquid onto the surface to be cleaned, and the suction component is capable of absorbing liquid onto the surface to be cleaned by negative pressure.

[0036] In one of the linear movement directions of the window cleaning robot, at least one of the liquid-absorbing components is located between the liquid-spraying component and the suction component;

[0037] The cleaning component is configured such that, during the movement of the window cleaning robot along a first linear direction, the spraying component has a first unit time spray volume; and during the period from the moment the window cleaning robot collides with the solid edge of the window until it moves along a second linear direction, the spraying component has a second unit time spray volume, and the suction component does not stop working.

[0038] The first linear movement direction and the second linear movement direction are opposite and parallel;

[0039] The amount of liquid sprayed per unit time in the second unit time shall not be greater than the amount of liquid sprayed per unit time in the first unit time;

[0040] The window cleaning robot also includes a walking device installed on the main unit, which enables the main unit to move on the surface to be cleaned.

[0041] One type of window cleaning robot includes: a main unit capable of adhering to and moving on a surface to be cleaned; an adsorption element disposed on the main unit, allowing the main unit to attach to the surface to be cleaned via the adsorption element; and a cleaning component comprising a spraying element and a suction element both disposed on the main unit, wherein the spraying element sprays liquid onto the surface to be cleaned, and the suction element absorbs liquid from the surface to be cleaned by negative pressure; in one of the linear movement directions of the window cleaning robot, at least one of the suction elements is located between the spraying element and the adsorption element; the window cleaning robot also includes a walking device disposed on the main unit, allowing the main unit to move on the surface to be cleaned via the walking device; these technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0042] Furthermore, it is defined that during the process of the window cleaning robot moving along the first straight-line movement direction, the window cleaning robot is in a straight-line operation state; after the window cleaning robot collides with the physical edge of the window and before it moves along the second straight-line movement direction, the window cleaning robot is in a path switching state that switches between the state of moving along the first straight-line movement direction and the state of moving along the second straight-line movement direction.

[0043] First, if the amount of cleaning fluid sprayed per unit time by the window cleaning robot in path-switching mode is greater than that in straight-line operation mode, then the cleaning robot will spray too much cleaning fluid at the solid edge of the window. On the one hand, the excessive cleaning fluid will flow into the gap between the solid edge of the window and the surface to be cleaned, affecting the sealing effect of the gap. On the other hand, the excessive cleaning fluid will also flow down the surface to be cleaned and stagnate under the action of gravity. When the window cleaning robot cleans the lower area, the spraying component will also spray out cleaning fluid. At this time, the lower area will not only have stagnant cleaning fluid, but also the cleaning fluid sprayed out by the spraying component. The cleaning fluid that is not absorbed by the suction component will easily come into contact with the suction component, affecting the adsorption effect of the window cleaning robot on the surface to be cleaned. On the other hand, since the cleaning fluid in a single cleaning operation is constant, if the amount of cleaning fluid is increased every time the window cleaning robot switches paths, the cleaning fluid will be wasted, accelerating the consumption rate of the cleaning fluid. This will prevent the window cleaning robot from cleaning more areas and will require frequent replenishment of cleaning fluid to clean more areas, resulting in poor battery life per cleaning operation.

[0044] If the amount of cleaning fluid sprayed per unit time by the window cleaning robot in path-switching mode is equal to that in straight-line operation mode, on the one hand, since the robot does not spray more cleaning fluid when in path-switching mode, it will not cause the cleaning fluid to flow into the gaps between the window edge and the surface to be cleaned, thus affecting the sealing effect of the gaps. The robot can also effectively absorb the cleaning fluid, preventing excessive fluid from flowing downwards and making it difficult to effectively clean the lower areas, which could weaken the adsorption effect of the suction components. On the other hand, since the robot does not increase the spray volume each time it enters path-switching mode, the cleaning fluid will not be depleted faster, allowing the robot to clean more areas without frequently adding cleaning fluid, resulting in better endurance per cleaning cycle.

[0045] If the amount of cleaning fluid sprayed per unit time by the window cleaning robot in path-switching mode is less than that in straight-line operation mode, on the one hand, because the robot sprays less cleaning fluid in path-switching mode, it can better ensure that the cleaning fluid does not flow into the gaps between the window edge and the surface to be cleaned, thus affecting the sealing effect of the gaps. It also ensures that the robot absorbs the cleaning fluid more completely, preventing incomplete absorption that could lead to contact between the cleaning fluid and the suction device, reducing its adsorption effect. On the other hand, because the robot reduces the amount of fluid sprayed each time it switches to path-switching mode, more cleaning fluid is used for window cleaning in straight-line operation mode, allowing the robot to clean more areas and improving its single-cleaning endurance.

[0046] If the suction component stops working when the window cleaning robot is in the path switching state, the cleaning liquid sprayed by the spray component cannot be effectively absorbed during this process. This causes the cleaning liquid to easily come into contact with the suction component, weakening the suction effect of the suction component. Consequently, the window cleaning robot cannot adhere to the surface to be cleaned and there is a risk of it falling.

[0047] If the window cleaning robot remains operational during path switching, the suction unit continues to effectively absorb the cleaning fluid, preventing the fluid from easily contacting the suction device and ensuring strong adhesion. Furthermore, the suction unit can utilize its negative pressure to absorb dust and debris near the window's edges, enhancing the robot's cleaning performance.

[0048] Therefore, by ensuring that the amount of liquid sprayed by the window cleaning robot in the second unit time is no greater than that in the first unit time, and by ensuring that the suction component does not stop working, the cleaning liquid sprayed by the spray component can be effectively absorbed by the suction component. The cleaning liquid will not come into contact with the suction component and affect its adsorption performance. At the same time, the suction component can also use its negative pressure to absorb floating dust and debris at the edge of the window, improving the cleaning effect of the window cleaning robot. Moreover, the cleaning liquid can be used reasonably, making the window cleaning robot have better endurance for a single cleaning cycle. In addition, the cleaning liquid sprayed by the spray component will not affect the sealing of the gap between the edge of the window and the surface to be cleaned.

[0049] According to a fourth aspect of this application, this application provides a window cleaning robot, comprising:

[0050] The host unit is capable of adhering to and moving on the surface to be cleaned.

[0051] An adsorption element, wherein the adsorption element is disposed on the main unit, and the main unit is capable of adhering to the surface to be cleaned via the adsorption element; and

[0052] The cleaning component includes a spraying component and a suction component, both disposed on the main unit. The spraying component is capable of spraying liquid onto the surface to be cleaned, and the suction component is capable of absorbing liquid onto the surface to be cleaned by negative pressure.

[0053] In one of the linear movement directions of the window cleaning robot, at least one of the liquid-absorbing components is located between the liquid-spraying component and the suction component;

[0054] The cleaning component is configured such that, during the movement of the window cleaning robot along a first linear direction, the suction element has a first average suction force; and during the period from the moment the window cleaning robot collides with the solid edge of the window until it moves along a second linear direction, in at least one position of the window cleaning robot during the above process, the suction force of the suction element is not greater than the first average suction force.

[0055] The first linear movement direction and the second linear movement direction are opposite and parallel;

[0056] The window cleaning robot also includes a walking device installed on the main unit, which enables the main unit to move on the surface to be cleaned.

[0057] One type of window cleaning robot includes: a main unit capable of adhering to and moving on a surface to be cleaned; an adsorption element disposed on the main unit, allowing the main unit to attach to the surface to be cleaned via the adsorption element; and a cleaning component comprising a spraying element and a suction element both disposed on the main unit, wherein the spraying element sprays liquid onto the surface to be cleaned, and the suction element absorbs liquid from the surface to be cleaned by negative pressure; in one of the linear movement directions of the window cleaning robot, at least one of the suction elements is located between the spraying element and the adsorption element; the window cleaning robot also includes a walking device disposed on the main unit, allowing the main unit to move on the surface to be cleaned via the walking device; these technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0058] Furthermore, it is defined that during the process of the window cleaning robot moving along the first straight-line movement direction, the window cleaning robot is in a straight-line operation state; after the window cleaning robot collides with the physical edge of the window and before it moves along the second straight-line movement direction, the window cleaning robot is in a path switching state that switches between the state of moving along the first straight-line movement direction and the state of moving along the second straight-line movement direction.

[0059] If the suction force of the window cleaning robot is greater than the first average suction force after it collides with the solid edge of the window and before it moves along the second straight-line direction, that is, during the process of the window cleaning robot switching from the straight-line movement state to the path switching state, the suction force of the liquid suction component will increase. On the one hand, the movement resistance of the window cleaning robot will also increase accordingly, which will slow down the movement speed of the window cleaning robot and prolong the working time of the window cleaning robot, thus reducing the working efficiency of the window cleaning robot. On the other hand, there are usually feathers, leaves and other debris on the surface of the window to be cleaned. During the movement, the window cleaning robot will push these debris to the vicinity of the solid edge of the window, and then the user will clean them manually. If the suction force of the liquid suction component increases during the path switching state, it will absorb some of these debris, causing the liquid suction component to become clogged, affecting its liquid absorption performance, reducing the cleaning ability of the window cleaning robot, requiring the user to clean the liquid suction component frequently, which will also lead to a decrease in the working efficiency of the window cleaning robot.

[0060] By ensuring that the suction force of the window cleaning robot is equal to the first average suction force during the process from the moment it collides with the solid edge of the window until it moves along the second linear direction, the suction force of the liquid-absorbing component remains unchanged during the transition from linear movement to path switching. This means that the robot's movement resistance remains constant, and its speed remains essentially constant, resulting in a reasonable working time and ensuring its efficiency. Furthermore, the robot can smoothly push debris such as feathers and leaves near the solid edge of the window. Even during path switching, the liquid-absorbing component will not become clogged due to the suction of these debris, ensuring its liquid absorption performance and cleaning ability. This eliminates the need for frequent cleaning of the spray nozzle, further enhancing the robot's efficiency.

[0061] Furthermore, during the process from when the window cleaning robot collides with the solid edge of the window until it moves along the second linear direction, its suction force is less than the first average suction force. As the window cleaning robot switches from linear movement to path switching, the suction force of the liquid-absorbing component decreases. On one hand, the movement resistance of the window cleaning robot decreases; on the other hand, the movement speed of the window cleaning robot increases during path switching, shortening its working time and improving its efficiency. Correspondingly, the window cleaning robot can also smoothly push debris such as feathers and leaves to the vicinity of the solid edge of the window, preventing the liquid-absorbing component from becoming clogged due to sucking in these debris. This ensures the liquid absorption performance of the liquid-absorbing component, guaranteeing the cleaning ability of the window cleaning robot and eliminating the need for frequent cleaning of the spray nozzle by the user, thus ensuring the efficiency of the window cleaning robot.

[0062] Therefore, during the process from the moment the window cleaning robot collides with the physical edge of the window until it moves along the second linear direction, its suction force is no greater than the first average suction force, which enables the window cleaning robot to ensure its working efficiency and even improve its working efficiency.

[0063] Optionally, according to one embodiment of this application, the cleaning component is configured such that, during the movement of the window cleaning robot along the first linear movement direction, when the window cleaning robot is located in three of the positions, the liquid suction component has a second suction force, a third suction force, and a fourth suction force, respectively.

[0064] The first average suction force is the average of the sum of the second suction force, the third suction force, and the fourth suction force.

[0065] Optionally, the cleaning component is configured such that, as the window cleaning robot moves along the second linear direction of movement, the liquid suction element has a second average suction force;

[0066] During the process from the moment the window cleaning robot collides with the physical edge of the window until it moves along the second linear direction, the window cleaning robot is in at least one position during the process described above, and the suction force of the liquid suction component is not greater than the second average suction force.

[0067] Understandably, as the window cleaning robot moves along the second straight-line direction, it is also in a straight-line operation state. The second average suction force can be equal to the first average suction force. In this way, whether the window cleaning robot is moving along the first straight-line direction or not, the suction force of the liquid suction component can remain relatively consistent. Consequently, the cleaning ability and cleaning intensity can also remain relatively consistent. This ensures that after the window cleaning robot completes its cleaning work, there will be no intermittently distributed patterned water stains on the window, thus ensuring the aesthetics of the window.

[0068] Optionally, the cleaning component is configured such that, during the movement of the window cleaning robot along the second linear direction, when the window cleaning robot is in one of three positions, the liquid suction component has a fifth suction force, a sixth suction force, and a seventh suction force, respectively.

[0069] The second average suction force is the average of the sum of the fifth suction force, the sixth suction force, and the seventh suction force.

[0070] Optionally, according to one embodiment of this application, an opening is provided on the host at a position corresponding to the spraying component and the suction component, and the spray nozzle of the spraying component and the suction nozzle of the suction component are both exposed through the opening.

[0071] By exposing the spray nozzle of the spraying component and the suction nozzle of the suction component through openings, the spray nozzle sprays out cleaning fluid through the openings, and the suction nozzle absorbs liquid through the openings.

[0072] There can be only one opening, through which both the spray nozzle of the spray component and the suction nozzle of the suction component are exposed. In this way, the main unit does not need to have two separate openings for the spray nozzle and the suction nozzle, resulting in better external integrity of the main unit.

[0073] Optionally, according to one embodiment of this application, the opening includes a first opening and a second opening that are independent of each other, the liquid suction port of the liquid suction member is exposed through the first opening, and the liquid spraying port of the liquid spraying member is exposed through the second opening.

[0074] In this way, the suction port of the suction component and the spray port of the spray component are exposed through the first opening and the second opening respectively, which can independently separate the spray port and the suction port, making it easier to disassemble and maintain one of them separately.

[0075] Optionally, according to one embodiment of this application, the host has a first surface and a second surface, the first surface facing the surface to be cleaned, and the second surface facing one of the linear movement directions;

[0076] The first opening is located on the first surface, the second opening is located on the second surface, and the spraying component is capable of spraying liquid onto the surface to be cleaned through the second opening along one of the linear movement directions.

[0077] In this way, the window cleaning robot sprays liquid in front of it, so that the area in front of the window cleaning robot is pre-sprayed with cleaning liquid, giving the dirt on it time to mix or react with the cleaning liquid, while the suction part is directly facing the surface to be cleaned to absorb the cleaning liquid.

[0078] Optionally, according to one embodiment of this application, the host has a first surface facing the surface to be cleaned;

[0079] Both the first opening and the second opening are located on the first surface.

[0080] This makes it easier for the liquid suction component to absorb the liquid, because the area where the liquid is sprayed by the liquid spray component and the area where the liquid is absorbed by the liquid suction component are relatively close, and both are located on the first surface.

[0081] Optionally, according to one embodiment of this application, the suction force of the liquid suction member at the liquid suction port is less than the suction force of the adsorption member at the adsorption port.

[0082] Therefore, it is necessary to prevent the suction components from generating excessive negative pressure, which would cause them to adhere to the surface to be cleaned and create additional resistance to the movement of the window cleaning robot.

[0083] Optionally, according to one embodiment of this application, the cleaning component further includes a scraper disposed on the host unit, wherein the scraper is located between the suction unit and the adsorption unit in one of the linear movement directions of the window cleaning robot, and the scraper is used to scrape off liquid from the surface to be cleaned.

[0084] When the window cleaning robot is working, the squeegee comes into contact with the surface to be cleaned, thereby affecting the direction of the cleaning fluid movement. In particular, it scrapes away the cleaning fluid that is not completely absorbed by the suction component before the suction component. Furthermore, when scraping the cleaning fluid, it can make the cleaning fluid evenly distributed into a very thin cleaning fluid film on the surface to be cleaned, thereby improving the work efficiency of wiping the surface to be cleaned by the wiping component.

[0085] Optionally, according to one embodiment of this application, the cleaning component further includes a scraper disposed on the host unit, wherein the scraper is located between the suction unit and the adsorption unit in one of the linear movement directions of the window cleaning robot, and the scraper is used to scrape off liquid from the surface to be cleaned;

[0086] The scraping component includes a first scraping section and a second scraping section spaced apart along one of the linear movement directions, and the suction port of the suction component is exposed between the first scraping section and the second scraping section.

[0087] The two scraping sections allow for better removal of liquid and further prevent excess cleaning fluid from flowing onto the suction unit. The suction port of the suction unit is exposed between the first and second scraping sections, ensuring that the suction airflow of the suction unit is not obstructed by the scraping sections and enabling better absorption of surrounding liquid.

[0088] Optionally, according to one embodiment of this application, at least a portion of the projection of the adsorption surface of the adsorption member onto the scraper in one of the linear movement directions.

[0089] In this configuration, at least part, and especially all, of the cleaning fluid flowing toward the adsorption surface of the adsorption element along one of the linear movement directions is scraped away by the scraper. This arrangement ensures that part, and especially all, of the cleaning fluid flowing toward the adsorption surface of the adsorption element is scraped away first by the scraper, further preventing any cleaning fluid that may not have been completely absorbed by the adsorption element from entering the adsorption surface of the adsorption element.

[0090] Optionally, according to one embodiment of this application, the cleaning component further includes a wiping member disposed on the host unit, wherein at least a portion of the wiping member is located between the scraping member and the adsorption member in one of the linear movement directions of the window cleaning robot, and the wiping member is used to wipe the surface to be cleaned.

[0091] In this way, at least part of the wiping component falls between the scraping component and the adsorption component. This arrangement ensures that the cleaning fluid flows through the wiping component as it flows towards the adsorption component, allowing the wiping component to absorb the cleaning fluid flowing towards the adsorption component and simultaneously have sufficient wiping area in all directions of movement of the window cleaning robot. It can also absorb the cleaning fluid in other locations on the surface to be cleaned, so as to better wipe the surface to be cleaned with the cleaning fluid.

[0092] Optionally, according to one embodiment of this application, the spraying component includes a first nozzle and a second nozzle both disposed on the host, wherein the axis of the first nozzle and the axis of the second nozzle intersect in one of the linear movement directions; or, the spraying component includes a spray pipe with a plurality of spray holes disposed on the spray pipe, the plurality of spray holes being spaced apart along the length direction of the spray pipe.

[0093] In this way, the cleaning fluid sprayed from the two nozzles can cover a large area of ​​the surface to be cleaned, forming a fan-shaped spray area. Alternatively, the paths of the cleaning fluid sprayed from the two nozzles can intersect, causing the fluid to impact each other, for example, falling onto the surface in a mist form, thus resulting in a more even distribution of the cleaning fluid on the surface.

[0094] Optionally, according to one embodiment of this application, the cleaning component includes two cleaning components, which are located on opposite sides of the suction element in one of the linear movement directions of the window cleaning robot.

[0095] In one of the linear movement directions, two cleaning components are located on both sides of the suction unit. That is, the window cleaning robot has two cleaning components, one in front and one behind, along one of the linear movement directions, so that the cleaning liquid sprayed by the cleaning components can cover a larger area of ​​the surface to be cleaned.

[0096] Meanwhile, the window cleaning robot can perform window cleaning work more flexibly. The window cleaning robot can move forward or backward along one of the straight-line movement directions and can perform window cleaning work in either direction. Since the window cleaning robot has two cleaning components, one in front and one behind, when the window cleaning robot needs to switch 180° of movement direction for cleaning, it does not need to turn 180° to clean. This effectively reduces the switching path required for the window cleaning robot to switch movement directions and improves the cleaning efficiency of the window cleaning robot.

[0097] Optionally, according to one embodiment of this application, when the window cleaning robot moves along one of the linear movement directions and performs window cleaning work, the cleaning component in front of the suction member along the movement direction of the window cleaning robot is activated, while the cleaning component in behind the suction member along the movement direction of the window cleaning robot is not activated.

[0098] In this way, when the window cleaning robot moves in other directions, especially in the opposite direction to the initial linear movement direction, a cleaning component positioned after the suction unit along the initial linear movement direction can be used for cleaning. This ensures that the cleaning component, positioned before the suction unit along the robot's movement direction, sprays liquid, guaranteeing that the path the robot will clean is already sprayed with cleaning fluid, rather than spraying cleaning fluid onto the path the robot has already traversed.

[0099] Optionally, according to one embodiment of this application, it further includes a liquid suction pump disposed on the host, the liquid suction pump being connected to the liquid suction element, and the liquid suction element being able to generate negative pressure under the drive of the liquid suction pump.

[0100] In this way, the suction component can generate negative pressure through the suction pump to absorb the cleaning liquid.

[0101] According to a fifth aspect of this application, a base station is provided for a window cleaning robot. The window cleaning robot includes a main unit capable of moving on a surface to be cleaned, an adsorption component disposed on the main unit, and a cleaning assembly disposed on the main unit. The cleaning assembly includes a spray component and an suction component both disposed on the main unit. In one of the linear movement directions of the window cleaning robot, at least one of the suction components is located between the spray component and the adsorption component. The window cleaning robot also includes a walking device disposed on the main unit, enabling the main unit to move on the surface to be cleaned via the walking device.

[0102] A liquid suction pump is provided in the base station. The liquid suction pump is used to connect to the liquid suction device, and the liquid suction device can generate negative pressure under the drive of the liquid suction pump.

[0103] The window cleaning robot includes a main unit capable of moving on the surface to be cleaned, an adsorption component mounted on the main unit, and a cleaning assembly mounted on the main unit.

[0104] In this way, the suction pump is not located on the main unit, but in the base station that can be placed on the ground or windowsill, which reduces the weight of the main unit of the window cleaning robot, improves its working efficiency, and saves energy consumption of the window cleaning robot.

[0105] According to a sixth aspect of this application, a base station is provided for a window cleaning robot. The window cleaning robot includes a main unit capable of moving on a surface to be cleaned, an adsorption component disposed on the main unit, and a cleaning assembly disposed on the main unit.

The window cleaning robot also includes a walking device mounted on the main unit, which enables the main unit to move on the surface to be cleaned. These technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0109] By supplying liquid to the window cleaning robot through the liquid storage chamber in the base station and recovering contaminated liquid from the window cleaning robot, the entire cleaning system does not require an external water source or wastewater treatment device, thus improving the independence of the cleaning system.

[0110] The liquid absorbed by the suction unit, which is contaminated by dirt on the window, is first purified by the purification unit and then transported back to the storage chamber through the contaminated liquid pipeline, thus realizing the recycling of the cleaning liquid.

[0111] According to a seventh aspect of this application, a base station is provided for a window cleaning robot, wherein the window cleaning robot includes a main unit capable of moving on a surface to be cleaned, an adsorption component disposed on the main unit, and a cleaning component disposed on the main unit.

The window cleaning robot also includes a walking device disposed on the main unit, and the main unit is capable of moving on the surface to be cleaned via the walking device.

[0112] The base station is equipped with a cleaning liquid chamber and a contaminated liquid chamber. The cleaning liquid chamber is connected to the spraying device via a cleaning liquid pipeline to supply liquid to the spraying device. The contaminated liquid chamber is connected to the suction device via a contaminated liquid pipeline to recover contaminated liquid from the suction device.

[0113] The window cleaning robot includes a main unit capable of moving on the surface to be cleaned, an adsorption component mounted on the main unit, and a cleaning assembly mounted on the main unit. The cleaning assembly includes a spray component and an adsorption component, both mounted on the main unit. In one of the linear movement directions of the window cleaning robot, at least one adsorption component is located between the spray component and the adsorption component. The window cleaning robot also includes a walking device mounted on the main unit, which enables the main unit to move on the surface to be cleaned. These technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0114] By setting up separate cleaning fluid chambers and contaminated fluid chambers, the cleaning fluid delivered to the spraying component and the contaminated liquid sucked back by the suction component each have their own storage chambers. This facilitates the differentiation between the two liquids and prevents contaminated liquid from mixing into the clean cleaning fluid and causing contamination.

[0115] Optionally, according to one embodiment of the seventh aspect of this application, the cleaning liquid chamber and the contaminated liquid chamber are connected by a purification element.

[0116] Therefore, the contaminated liquid in the dirty liquid chamber can be purified by the purification unit and then directly transported to the clean liquid chamber as a cleaning solution for use in the spraying unit, thus realizing the recycling of the cleaning solution. Furthermore, the separate design of the dirty liquid chamber and the clean liquid chamber allows sufficient time for the purification process of the liquid in the dirty liquid chamber.

[0117] According to an eighth aspect of this application, a composite pipeline is provided for connecting a window cleaning robot and a base station. The window cleaning robot includes a main unit capable of moving on a surface to be cleaned, an adsorption component disposed on the main unit, and a cleaning assembly disposed on the main unit. The cleaning assembly includes a spray component and an adsorption component both disposed on the main unit. In one of the linear movement directions of the window cleaning robot, at least one of the adsorption components is located between the spray component and the adsorption component. The window cleaning robot also includes a walking device disposed on the main unit, and the main unit is capable of moving on the surface to be cleaned via the walking device.

[0118] The composite pipeline includes:

[0119] A cleaning fluid pipeline connects the base station to the spray nozzle to deliver the liquid;

[0120] A contaminated liquid pipeline, which connects the liquid suction device to the base station, for transporting contaminated liquid;

[0121] The tubing is encased within the cleaning fluid tubing and the contaminated fluid tubing.

[0122] The window cleaning robot includes a main unit capable of moving on the surface to be cleaned, an adsorption component mounted on the main unit, and a cleaning assembly mounted on the main unit. The cleaning assembly includes a spray component and an adsorption component, both mounted on the main unit. In one of the linear movement directions of the window cleaning robot, at least one adsorption component is located between the spray component and the adsorption component. The window cleaning robot also includes a walking device mounted on the main unit, which enables the main unit to move on the surface to be cleaned. These technical features correspond to the relevant technical solutions in the first aspect of this application, and the beneficial effects achieved are the same as those in the first aspect of this application, and will not be repeated here.

[0123] The composite pipeline includes a cleaning fluid pipeline for delivering cleaning fluid to the spray nozzle and a sludge fluid pipeline for recovering contaminated liquid from the suction nozzle. This ensures that the cleaning fluid and contaminated liquid are delivered through two separate pipelines without mixing and contaminating the clean cleaning fluid. The cleaning fluid pipeline and the sludge fluid pipeline are encased in a composite pipeline, which saves space required for wiring and also increases the strength and toughness of the pipeline.

[0124] Optionally, according to an embodiment of the eighth aspect of this application, the composite pipeline further includes a power line connecting the base station and the window cleaning robot for power transmission, wherein the power line, the cleaning fluid pipeline, and the sludge fluid pipeline are encased in the encased pipeline.

[0125] Therefore, the window cleaning robot is powered by a base station, without needing to be directly connected to a power source. The power cord can also be encased in a protective conduit to form a composite conduit, protecting the power cord from damage if exposed, saving wiring space, and further increasing the strength and toughness of the composite conduit.

[0126] Optionally, according to an embodiment of the eighth aspect of this application, the composite pipeline further includes a safety rope connecting the base station and the window cleaning robot. The base station can provide tension to the window cleaning robot via the safety rope after the window cleaning robot detaches from the surface to be cleaned. The safety rope, the cleaning fluid pipeline, and the sludge fluid pipeline are encased in the encased pipeline.

[0127] A safety rope connected at one end to the base station prevents the window cleaning robot from falling to the ground and being damaged if it drops from the surface to be cleaned. The safety rope also suspends the robot in mid-air when it falls. Encasing the safety rope within the composite tubing saves storage space and further increases the strength and toughness of the composite tubing.

[0128] Optionally, according to one embodiment of the eighth aspect of this application, the base station is able to provide pulling force to the window cleaning robot through the covered pipeline after the window cleaning robot detaches from the surface to be cleaned.

[0129] Therefore, the entire covered pipeline, or composite pipeline, can act as a safety rope to prevent the window cleaning robot from falling to the ground and breaking, allowing it to withstand greater pulling force from the window cleaning robot and further reducing the risk of the window cleaning robot falling to the ground.

[0172] It is readily understood that, based on the technical solution of this application, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of this application.

[0173] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used for descriptive and distinguishing purposes only and should not be construed as indicating or implying the relative importance of the corresponding components or the order of components or assembly sequence.

[0174] In related technologies, a window cleaning robot is a device that can move on a window and clean the surface of the window to be cleaned during the movement.

[0175] Window cleaning robots are typically equipped with suction cups, wheels, nozzles, and cloths. The robot attaches to the surface to be cleaned using the suction cups and moves across it using the wheels. Simultaneously, the nozzles spray liquid onto the surface, which is then wiped clean with the cloth.

[0176] However, the cleaning cloth's absorption capacity for cleaning solution is limited. As cleaning continues, the cloth's absorbency gradually weakens, and it may even become unable to absorb any cleaning solution at all. This causes the cleaning solution to flow around the suction cup or enter the suction cup's adsorption chamber, making it difficult for the window cleaning robot to maintain its adherence to the surface to be cleaned. This increases the risk of the window cleaning robot falling off the surface. Therefore, the cloth needs to be replaced frequently to ensure the window cleaning robot can work continuously, resulting in low work efficiency and a poor user experience.

[0177] Moreover, due to the limited absorption capacity of the cloth, the spray nozzle can only use intermittent spraying of liquid to ensure that the window cleaning robot can work for a long time. However, this cleaning method has poor cleaning effect and is difficult to deal with dirty surfaces. It can only clean the surface multiple times, which also leads to low work efficiency and poor user experience of the window cleaning robot.

[0178] In summary, window cleaning robots in related technologies suffer from poor cleaning performance and low work efficiency.

[0179] This application proposes a window cleaning robot with excellent cleaning effect and high work efficiency. (Reference) Figure 1 This diagram illustrates the bottom structure of a window cleaning robot 10 according to one embodiment of the present application, facing the surface to be cleaned. The window cleaning robot 10 includes a main unit 100, an adsorption component 200, a cleaning assembly 300, and a walking device. The adsorption component 200 and the cleaning assembly 300 are both mounted on the main unit 100. For ease of description, the surface of the window cleaning robot 10 facing the surface to be cleaned is defined as the "bottom surface," and the surface connected to the bottom surface and at an angle to the surface to be cleaned is defined as the "side surface." Furthermore, it should be understood that "front" or "rear" of the window cleaning robot 10 in the following description refers to the front or rear relative to the direction of movement of the window cleaning robot 10.

[0180] The main unit 100 can adhere to and move on the surface to be cleaned via the suction element 200. The walking device can be wheels or tracks 400. The main unit moves on the surface to be cleaned via the wheels or tracks 400, thereby driving the cleaning component 300 to move at different positions on the surface, thus enabling the cleaning component 300 to clean different positions on the surface. In the following description, the linear movement direction of the window cleaning robot 10 can be as follows: Figure 1 The length direction of the traveling track 400 of the window cleaning robot 10 shown.

[0181] For example, refer to Figure 6 , Figure 6 This is a schematic diagram of the window cleaning robot 10 moving in the first linear direction; see reference. Figure 7 , Figure 7 This is a schematic diagram illustrating the movement of the window cleaning robot 10 after colliding with the physical edge of the window and before moving in the second linear direction; see reference. Figure 8 , Figure 8 This is a schematic diagram showing movement in the second linear direction.

[0182] The direction of linear movement can be Figure 6 , Figure 7 or Figure 8 The diagram shows the direction of movement of the window cleaning robot.

[0183] The adsorption component 200 can be a suction cup, or it can be any other component that is adsorbed onto the surface to be cleaned by negative pressure. No specific limitation is made here.

[0184] The suction component 200 adheres to the surface to be cleaned through negative pressure. It is understood that the suction effect of the suction component 200 does not affect the movement of the window cleaning robot on the surface to be cleaned via the travel wheels or travel track 400 (e.g., movement parallel to the surface to be cleaned). The suction component 200 can be arranged at the center of the bottom surface of the main unit 100.

[0185] The cleaning component 300 includes a spraying component 310 and a suction component 320, both disposed on the main unit 100. The spraying component 310 sprays liquid onto the surface to be cleaned, and the suction component 320 absorbs the liquid onto the surface to be cleaned by applying negative pressure. In one of the linear movement directions of the window cleaning robot 10, the suction component 320 is located between the spraying component 310 and the suction component 200. For example, in the first linear movement direction of the window cleaning robot 10, the suction component 320 may be located between the spraying component 310 and the suction component 200.

[0186] On the one hand, the suction member 320 can absorb the cleaning liquid on the surface to be cleaned. In this way, the cleaning liquid on the surface to be cleaned will be absorbed by the suction member 320 before it comes into contact with the adsorption surface of the adsorption member 200, so as to prevent the cleaning liquid from coming into contact with the adsorption surface of the adsorption member 200 and flowing into the adsorption chamber of the adsorption member 200, thereby reducing the adsorption effect of the adsorption member 200 on the surface to be cleaned.

[0187] On the other hand, the liquid suction component 320 can not only absorb cleaning liquid, but also use its negative pressure to absorb other liquids, dust and debris remaining on the surface to be cleaned, so as to further improve the window cleaning effect of the window cleaning robot. For example, the liquid suction component can also absorb rainwater, dirty water and other liquids, dust and debris remaining on the surface to be cleaned.

[0188] On the other hand, the liquid suction component 320 can also achieve self-cleaning using cleaning fluid to improve the utilization rate of cleaning fluid. Specifically, when the liquid suction component 320 absorbs cleaning fluid, the cleaning fluid will flow on the wall of the liquid suction chamber of the liquid suction component 320 to clean the wall of the liquid suction chamber, thus achieving self-cleaning of the liquid suction component 320.

[0189] In one embodiment of this application, the distance between the at least one liquid-absorbing element and the liquid-spraying element is greater than or equal to 1 cm and less than or equal to 6 cm.

The window cleaning robot 10 can control the spray pump of the spraying component 310 to adjust the spray volume of the spraying component 310 according to the different movement states described above.

[0191] In another embodiment of this application, the cleaning component 300 is configured such that, during the movement of the window cleaning robot 10 along a first linear movement direction, the liquid suction member 320 has a first average suction force; and during the process from the moment the window cleaning robot 10 collides with the solid edge 6 of the window until it moves along a second linear movement direction, the window cleaning robot 10 is in at least one position of the above process, and the suction force of the liquid suction member 320 is not greater than the first average suction force; the first linear movement direction and the second linear movement direction are opposite and parallel.

[0195] In one embodiment of this application, for example Figure 1In this embodiment, openings 110 are provided on the main unit 100 at positions corresponding to the spraying component 310 and the suction component 320, and the spray nozzle of the spraying component 310 and the suction nozzle of the suction component 320 are both exposed through the openings 110. (See reference...) Figure 2 This illustrates a schematic diagram of the bottom structure of a window cleaning robot 10 according to another embodiment of this application, facing the surface 5 to be cleaned. Figure 2 In this embodiment, the opening 110 includes a first opening and a second opening that are independent of each other. The suction port of the suction member 320 is exposed through the first opening, and the spray port of the spray member 310 is exposed through the second opening. The main unit 100 has a first surface and a second surface. The first surface faces the surface to be cleaned 5, i.e., the aforementioned bottom surface, and the second surface faces one of the linear movement directions (taking the first linear movement direction as an example). The first opening is located on the first surface, and the second opening is located on the second surface (because the second opening is located on the second surface, in...). Figure 2 (Not explicitly shown), the spraying element 310 can spray liquid onto the surface 5 to be cleaned through the second opening along one of the linear movement directions (taking the first linear movement direction as an example). In another embodiment of this application, the main unit 100 can be configured such that it has a first surface facing the surface 5 to be cleaned; both the first opening and the second opening are located on the first surface. In this embodiment, the spraying element 310 sprays liquid toward the surface 5 to be cleaned, and the suction element 320 also absorbs the cleaning liquid toward the surface 5 to be cleaned.

[0196] In one embodiment of this application, the suction force at the suction port of the liquid suction member 320 is less than the suction force at the adsorption port of the adsorption member 200.

[0197] In one embodiment of this application, the cleaning assembly 300 further includes a scraper 330 disposed on the main unit. In one of the linear movement directions of the window cleaning robot 10 (taking the first linear movement direction as an example), the scraper 330 is located between the suction member 320 and the adsorption member 200 to scrape liquid off the surface 5 to be cleaned. The scraper 330 is, for example, a long, strip-shaped scraper that extends transversely to the bottom surface of the window cleaning robot 10 in one of the linear movement directions (taking the first linear movement direction as an example). The scraper 330 includes, for example, a first scraping portion and a second scraping portion spaced apart along one of the linear movement directions (taking the first linear movement direction as an example). Both the first and second scraping portions are, for example, configured as scraper strips extending perpendicular to the one of the linear movement directions (taking the first linear movement direction as an example).

[0198] In one embodiment of this application, the projection of the adsorption surface of the adsorption member 200 onto one of the linear movement directions (taking the first linear movement direction as an example) is at least partially, and especially completely, onto the scraper member 330.

[0199] In one embodiment of this application, the cleaning assembly 300 further includes a wiping member 340 disposed on the main unit. In one of the linear movement directions of the window cleaning robot 10 (taking the first linear movement direction as an example), at least a portion of the wiping member 340 is located between the wiper member 330 and the absorbent member 200 to wipe the surface 5 to be cleaned. The wiping member 340 is, for example, a soft material that can absorb water and is used for wiping, such as a cloth or sponge.

[0200] In one embodiment of this application (not shown in the drawings), the spraying component 310 includes a first nozzle and a second nozzle, both disposed on the host 100. The axis of the first nozzle and the axis of the second nozzle intersect in one of the linear movement directions (taking the first linear movement direction as an example). It should be understood that the spraying component 310 may also include one or more nozzles. In one embodiment of this application, the spraying component 310 may further include a spray pipe with a plurality of spray holes 311 disposed on the spray pipe, the plurality of spray holes 311 being spaced apart along the length direction of the spray pipe.

[0201] In one embodiment of this application, the window cleaning robot 10 includes two cleaning components. In one linear movement direction (taking the first linear movement direction as an example), the two cleaning components are located on either side of the suction member 200. That is, the window cleaning robot has two cleaning components, one in front and one behind, along one linear movement direction (taking the first linear movement direction as an example), so that the cleaning liquid sprayed by the cleaning components can cover a larger area of ​​the surface 5 to be cleaned. Furthermore, when the window cleaning robot 10 moves along one linear movement direction (taking the first linear movement direction as an example) to perform window cleaning work, the cleaning component in front of the suction member 200 along the movement direction of the window cleaning robot 10 is activated, while the cleaning component behind the suction member 200 along the movement direction of the window cleaning robot 10 is not activated.

[0202] In one embodiment of this application, the window cleaning robot 10 includes a liquid suction pump disposed on the host 100. The liquid suction pump is connected to a liquid suction component, which can generate negative pressure under the drive of the liquid suction pump.

[0203] Another aspect of this application proposes a base station 20 for the aforementioned window cleaning robot. (Reference) Figure 3 This diagram illustrates the structure of a base station 20 according to one embodiment of this application. A liquid suction pump is provided in the base station 20. Figure 3 (Not specifically shown in the text) The suction pump is used to connect to the suction component 320, which can generate negative pressure under the drive of the suction pump.

[0204] In another embodiment of this application, a liquid storage chamber 21 is provided on the base station 20. The liquid storage chamber 21 is connected to a spray nozzle 310 via a cleaning fluid line 301 to supply liquid to the spray nozzle 310, and is also connected to a suction nozzle 320 via a contaminated liquid line 302 to recover contaminated liquid from the suction nozzle 320. The liquid storage chamber 21 is connected to the contaminated liquid line 302 via a purification component. In this embodiment, the liquid storage chamber 21 stores cleaning fluid, which can be sprayed onto the surface 5 to be cleaned by the spray nozzle 310. The liquid absorbed by the suction nozzle 320, which is contaminated by dirt on the window, is first purified by the purification component and then transported back to the liquid storage chamber 21 via the contaminated liquid line 302, thus achieving the recycling of the cleaning fluid. The purification component is, for example, a filter, a water purifier, or a combination of a filter and a water purifier.

[0205] In another embodiment of this application, the base station 20 is provided with a separate cleaning liquid chamber 211 and a contaminated liquid chamber 212. The cleaning liquid chamber 211 is connected to the spray nozzle 310 via a cleaning liquid line 301 to supply liquid to the spray nozzle 310. The contaminated liquid chamber 212 is connected to the suction nozzle 320 via a contaminated liquid line 302 to recover contaminated liquid from the suction nozzle 320. In this embodiment, the cleaning liquid supplied to the spray nozzle 310 and the contaminated liquid absorbed from the suction nozzle 320 are stored in separate chambers. The cleaning liquid chamber 211 and the contaminated liquid chamber 212 are connected, for example, via a purification device, so that the contaminated liquid in the contaminated liquid chamber 212 can be purified by the purification device before flowing into the cleaning liquid chamber 211. This provides more time for purification or filtration from contaminated liquid to cleaning liquid, and ultimately achieves the recycling of the cleaning liquid. The purification device is, for example, a filter, a water purifier, or a combination of a filter and a water purifier.

[0206] This application also proposes a composite pipeline 30 for connecting the aforementioned window cleaning robot 10 and the aforementioned base station 20. (Reference) Figure 4 The diagram shows a cross-sectional view of a composite pipeline 30 according to one embodiment of this application. The composite pipeline 30 includes:

[0207] Cleaning fluid line 301 connects base station 20 and spray nozzle 310 to deliver liquid;

[0208] The contaminated liquid pipeline 302 connects the liquid suction unit 320 and the base station 20 to transport the contaminated liquid;

[0209] The encapsulation line 303 encapsulates the cleaning fluid line 301 and the turbid fluid line 302.

[0210] The composite pipeline 30 is an integrated pipeline. It is a single line formed by wrapping cleaning fluid pipeline 301, dirty fluid pipeline 302, etc. into multiple pipelines by wrapping pipeline 303, which saves wiring space and improves the strength and toughness of the composite pipeline 30 itself.

[0211] In one embodiment, the composite pipeline 30 further includes a power line 304 connecting the base station 20 and the window cleaning robot 10 for power transmission. The power line 304, the cleaning fluid pipeline 301, and the sludge fluid pipeline 302 are encased in an encased pipeline 303. The power line 304, for example, is connected to... Figure 4 As shown, it includes both positive and negative lines. When the window cleaning robot 10 is connected to the base station 20 via power cable 304, the power supply for the window cleaning robot 10 can be obtained, for example, directly from the power supply in the base station or from an external power supply connected to the base station.

[0212] In one embodiment, the composite pipeline 30 further includes a safety rope 305 connecting the base station 20 and the window cleaning robot 10. After the window cleaning robot 10 detaches from the surface 5 to be cleaned, the base station 20 provides tension to the window cleaning robot 10 via the safety rope 305, allowing the robot to be suspended in mid-air by the safety rope 305, instead of falling directly to the ground, thus preventing collision damage. The safety rope 305, the cleaning fluid pipeline 301, and the sludge fluid pipeline 302 are encased within the covered pipeline 303. The composite pipeline 30 may also include, for example, a power cord 304 and a safety rope 305 simultaneously, as shown in... Figure 4 As shown in the diagram, the power cord 304, safety rope 305, cleaning fluid line 301, and sludge fluid line 302 are all encased within the covering line 303. Furthermore, it should be understood that, especially when the safety rope 305 is encased within the covering line 303, forming part of the composite line 30, the covering line 303, or the composite line 30 as a whole, can also function as the safety rope 305, providing tension to the detached window cleaning robot 10 and preventing it from falling to the ground.

[0213] This application also proposes a window cleaning system 1, referenced to... Figure 5 This diagram illustrates a window cleaning system 1 according to one embodiment of the present application. The window cleaning system 1 includes one or more of the aforementioned window cleaning robot 10, base station 20, and composite pipeline 30. In a preferred embodiment, the window cleaning system 1 includes the aforementioned window cleaning robot 10, base station 20, and composite pipeline 30, and the window cleaning robot 10 and base station 20 are connected to each other via the composite pipeline 30.

[0214] It should be understood that all the above preferred embodiments are exemplary and not restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the scope of legal protection of this application.
