Description

Technical Field

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

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

[0003] A window cleaning robot is usually equipped with a suction cup, walking wheels, a nozzle, and a cleaning cloth. The window cleaning robot adsorbs on the surface to be cleaned through the suction cup and moves on the surface to be cleaned through the walking wheels. At the same time, the nozzle can spray liquid on the surface to be cleaned, and then the cleaning cloth wipes the surface to be cleaned.

[0004] However, the absorption capacity of the cleaning cloth for the cleaning liquid is limited. As the cleaning work continues, the water absorption capacity of the cleaning cloth will gradually weaken, and even be unable to absorb the cleaning liquid, resulting in the cleaning liquid flowing around the suction cup or entering the adsorption cavity of the suction cup, making it difficult for the window cleaning robot to maintain the state of adsorbing on the surface to be cleaned, increasing the risk of the window cleaning robot falling from the surface to be cleaned. Therefore, it is necessary to frequently replace the cleaning cloth to ensure the continuous operation of the window cleaning robot, resulting in low work efficiency of the window cleaning robot and poor user experience.

[0005] Moreover, affected by the limited absorption capacity of the cleaning cloth for liquid, the liquid spraying component can only clean by intermittently spraying liquid to ensure that the window cleaning robot can work for a long time. However, the cleaning effect of this cleaning method is poor and it is difficult to deal with a relatively dirty surface to be cleaned. It can only clean the surface to be cleaned multiple times, which also leads to low work efficiency of the window cleaning robot and poor user experience.

[0006] In summary, the window cleaning robot in the related art has the technical problems of poor cleaning effect and low work efficiency. Utility Model Content

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

[0008] In addition, other aspects of this application also aim 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 the first aspect of this application, a window cleaning robot, which includes:

[0010] A main body, the main body can adsorb on the surface to be cleaned and can move on the surface to be cleaned;

[0011] An adsorbent, the adsorbent is provided on the main body, and the main body can be attached to the surface to be cleaned through the adsorbent; and

[0012] A cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body, the liquid spraying member can spray liquid onto the surface to be cleaned, and the liquid absorbing member can absorb the liquid on the surface to be cleaned through negative pressure;

[0013] In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the adsorbent.

[0014] First, the main body can be adsorbed on the surface to be cleaned and can move on the surface to be cleaned, so that the cleaning component moves along with the main body, and then different positions of the surface to be cleaned are cleaned.

[0015] The cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body. The liquid spraying member can spray liquid onto the surface to be cleaned (the liquid can be water or a cleaning liquid for cleaning the glass surface). The liquid absorbing member can absorb the liquid on the surface to be cleaned through negative pressure. In one of the linear movement directions of the window cleaning robot, the liquid absorbing member is located between the liquid spraying member and the adsorbent.

[0016] On the one hand, during the process that the window cleaning robot moves along one of the linear movement directions and performs window cleaning work, the liquid spraying member sprays liquid onto the surface to be cleaned. As the window cleaning robot moves, it drives the liquid absorbing member to move to the liquid spraying position of the cleaning liquid, and the liquid absorbing member absorbs the cleaning liquid, so that before the cleaning liquid contacts the adsorbent on the surface to be cleaned, the cleaning liquid will be absorbed by the liquid absorbing member, preventing the cleaning liquid from contacting the adsorbent and entering the adsorption cavity of the adsorbent, ensuring that the adsorbent will not reduce or even lose its adsorption capacity, and preventing the window cleaning robot from falling from the surface to be cleaned; moreover, through the setting of the liquid absorbing member, the cleaning liquid does not need to be completely absorbed by the rag, extending the single working time of the rag, thereby extending the single working time of the window cleaning robot and avoiding the user from frequently replacing the rag, with good user experience. On the other hand, the liquid absorbing member can not only absorb the cleaning liquid, but also use its negative pressure effect to absorb other liquids, floating dust and fine 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 absorbing member can also absorb pollutants such as rainwater, dirty water, floating dust and fine debris remaining on the surface to be cleaned, improving the cleaning effect of the window cleaning robot. On the other hand, when the liquid absorbing member absorbs the cleaning liquid, the cleaning liquid will flow on the inner wall of the liquid absorption cavity of the liquid absorbing member to clean the inner wall of the liquid absorption cavity, thereby realizing self-cleaning of the liquid absorbing member and greatly improving the utilization rate of the cleaning liquid.

[0017] On the other hand, in the related art, affected by the limited liquid absorption capacity of the cleaning cloth, the liquid spraying member can only clean by intermittently spraying liquid to ensure that the window cleaning robot can work for a long time. However, this cleaning method is difficult to deal with a relatively dirty surface to be cleaned and can only meet the cleaning requirements by cleaning the surface to be cleaned multiple times. That is, for the window cleaning robot in the related art, when dealing with a surface to be cleaned with a relatively high degree of dirt, its cleaning effect is poor and its cleaning efficiency is also low. The present application proposes a window cleaning robot. When dealing with a surface to be cleaned with a relatively high degree of dirt, the liquid spraying member and the liquid absorbing member can work together. The liquid spraying member can continuously spray liquid to continuously wash and spray the surface to be cleaned, effectively improving the cleaning effect of the window cleaning robot. At the same time, the liquid absorbing member can effectively absorb the excess cleaning liquid and does not need to be completely absorbed by the cleaning cloth. Therefore, there is no need to frequently replace the cleaning cloth. In this way, the window cleaning robot can improve the cleaning effect of the window cleaning robot while also improving its working efficiency.

[0018] In summary, by setting a liquid absorbing member on the main body to absorb the cleaning liquid sprayed by the liquid spraying member, it is possible to ensure that the cleaning liquid does not need to be completely absorbed by the cleaning cloth, thereby extending the service life of the cleaning cloth. The user does not need to frequently replace the cleaning cloth, enabling the window cleaning robot to work for a long time and improving the working efficiency of the window cleaning robot, while providing a good user experience. Further, by absorbing the cleaning liquid, the cleaning liquid can also self-clean the inside of the liquid absorbing member, making full use of the cleaning liquid. Moreover, the liquid absorbing member can effectively absorb floating dust and fine debris to further improve the cleaning effect of the window cleaning robot. Further, the liquid absorbing member is arranged between the liquid spraying member and the suction attachment along one of the linear movement directions of the window cleaning robot, which can ensure that the cleaning liquid is absorbed by the liquid absorbing member before contacting the suction attachment, ensuring the adsorption performance of the suction attachment and ensuring that the window cleaning robot is not easily detached from the surface to be cleaned, thus ensuring good safety performance. Furthermore, the liquid spraying member and the liquid absorbing member can work together. When dealing with a relatively dirty surface to be cleaned, the liquid spraying member can continuously spray liquid to achieve the effect of washing and spraying the surface to be cleaned. Compared with the cleaning method in the related art that can only spray liquid at intervals, there is no need to perform multiple cleaning operations to complete the cleaning. At the same time, the liquid absorbing member can effectively absorb, so that the cleaning effect can be improved while the working efficiency can also be improved.

[0019] According to the second aspect of the present application, a window cleaning robot includes:

[0020] A main body that can adsorb on the surface to be cleaned and can move on the surface to be cleaned;

[0021] A suction attachment provided on the main body, and the main body can attach to the surface to be cleaned through the suction attachment; and

[0022] A cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both disposed on the main body. The liquid spraying member is capable of spraying liquid onto the surface to be cleaned, and the liquid absorbing member is capable of absorbing liquid on the surface to be cleaned through negative pressure.

[0023] In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment, and the distance between the at least one liquid absorbing member and the liquid spraying member is greater than or equal to 1 cm and less than or equal to 6 cm.

[0024] Wherein, a window cleaning robot includes: a main body, the main body is capable of adsorbing on the surface to be cleaned and capable of moving on the surface to be cleaned; a suction attachment, the suction attachment is disposed on the main body, and the main body is capable of attaching to the surface to be cleaned through the suction attachment; and a cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both disposed on the main body. The liquid spraying member is capable of spraying liquid onto the surface to be cleaned, and the liquid absorbing member is capable of absorbing liquid on the surface to be cleaned through negative pressure. In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment. These technical features correspond to the related technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, and will not be elaborated herein.

[0025] In order to ensure better cleaning effect when the liquid absorbing member and the liquid spraying member work together, the distance between the liquid absorbing member and the liquid spraying member is greater than or equal to 1 cm and less than or equal to 6 cm.

[0026] If the distance between the liquid absorbing member and the liquid spraying member is less than 1 cm, on the one hand, the distance between the liquid absorbing member and the liquid spraying member is too close, and most of the cleaning liquid sprayed by the liquid spraying member will be quickly absorbed by the liquid absorbing member, resulting in that the cleaning liquid fails to fully combine with the dirt on the surface to be cleaned, leading to poor cleaning effect. On the other hand, if the distance between the liquid absorbing member and the liquid spraying member is too close, when the liquid absorbing member and the liquid spraying member work together, the vibrations generated by the two are likely to affect each other, which will reduce the installation stability of the two on the main body and the working stability during collaborative work, making it difficult for the liquid absorbing member and the liquid spraying member to exert their due working performance, resulting in poor cleaning ability of the window cleaning robot.

[0027] It should be noted that the water absorption rate of the window cleaning robot can refer to: during the working process of the window cleaning robot, the ratio of the amount of water absorbed by the liquid absorbing member to the amount of water sprayed by the liquid spraying member, usually expressed as a percentage. This ratio reflects the absorption efficiency of the liquid absorbing member for the water sprayed by the liquid spraying member, so as to reflect 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.

[0028] Refer toFigure 9 , Figure 9 The relationship diagram between the water absorption rate of the window cleaning robot and the distance between the liquid absorption member and the liquid spraying member is shown. It can be seen that when the distance between the liquid absorption member and the liquid spraying member increases from 1 cm to 6 cm, the water absorption rate of the window cleaning robot gradually decreases as the distance gradually increases; when the distance between the liquid absorption member and the liquid spraying member is 6 cm, the water absorption rate of the window cleaning robot is 80%, which is the lowest acceptable water absorption rate for users; then when the distance between the liquid absorption member and the liquid spraying member is greater than 6 cm, the water absorption rate of the window cleaning robot is lower than 80%, which is an unacceptable water absorption rate for users. Since the distance between the liquid absorption member and the liquid spraying member is too far, when the liquid absorption member moves with the main body, it will reach the location of the cleaning liquid relatively slowly and cannot absorb the cleaning liquid in time. Part of the cleaning liquid that is not absorbed in time will flow downward due to gravity, resulting in the inability to ensure that most of the cleaning liquid remains in the preset cleaning area for the window cleaning robot to wipe, resulting in a poor cleaning effect, and also causing the cleaning liquid not to be fully utilized. Moreover, since part of the cleaning liquid flows downward and the window cleaning robot fails to wipe in time, water stains are formed in the lower area, requiring the window cleaning robot to perform secondary cleaning, resulting in a decrease in the cleaning efficiency of the window cleaning robot.

[0029] Therefore, setting the distance between the liquid spraying member and the liquid absorption member to be greater than or equal to 1 cm and less than or equal to 6 cm is a reasonable distance range. First, it makes the distance between the liquid absorption member and the liquid spraying member not too close, so that most of the cleaning liquid sprayed by the liquid spraying member remains in the preset cleaning area, and the cleaning liquid and dirt have sufficient fusion time, enabling the cleaning liquid and dirt to be fully fused before being absorbed by the liquid absorption member, so as to achieve a good cleaning effect of the window cleaning robot; at the same time, it enables the liquid absorption member and the liquid spraying member to work together without interfering with each other, enabling both to exert their due working performance to ensure the cleaning effect of the window cleaning robot; moreover, the distance between the liquid absorption member and the liquid spraying member is not too far, and the liquid absorption member can reach the location of the cleaning liquid faster as the window cleaning robot moves forward, can absorb the cleaning liquid in time, the water absorption rate of the window cleaning robot can be maintained at 80% or above, ensuring a good cleaning effect, not causing part of the cleaning liquid to flow downward, and not requiring the window cleaning robot to perform secondary cleaning. Moreover, it also ensures that all or most of the cleaning liquid remains in the preset cleaning area for the window cleaning robot to wipe, and can effectively utilize the cleaning liquid.

[0030] According to the third aspect of the present application, the present application provides a window cleaning robot, including:

[0031] A main body, the main body can be adsorbed on the surface to be cleaned and can move on the surface to be cleaned;

[0032] An adsorbent, the adsorbent is provided on the main body, and the main body can be attached to the surface to be cleaned through the adsorbent; and

[0033] A cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body, the liquid spraying member can spray liquid onto the surface to be cleaned, and the liquid absorbing member can absorb liquid on the surface to be cleaned through negative pressure;

[0034] In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the adsorbent;

[0035] The cleaning component is configured such that during the process of the window cleaning robot moving in the first linear movement direction, the liquid spraying member has a first liquid spraying volume per unit time; and during the process from after the window cleaning robot collides with the physical edge of the window to before moving in the second linear movement direction, the liquid spraying member has a second liquid spraying volume per unit time, and the liquid absorbing member does not stop working;

[0036] The first linear movement direction and the second linear movement direction are opposite and parallel;

[0037] The second liquid spraying volume per unit time is not greater than the first liquid spraying volume per unit time.

[0038] Wherein, a window cleaning robot includes: a main body, the main body can be adsorbed on the surface to be cleaned and can move on the surface to be cleaned; an adsorbent, the adsorbent is provided on the main body, and the main body can be attached to the surface to be cleaned through the adsorbent; and a cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body, the liquid spraying member can spray liquid onto the surface to be cleaned, and the liquid absorbing member can absorb liquid on the surface to be cleaned through negative pressure; in one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the adsorbent. These technical features correspond to the related technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, and will not be elaborated here.

[0039] Further, it is defined that during the process of the window cleaning robot moving in the first linear movement direction, the window cleaning robot is in a linear operation state; during the process from after the window cleaning robot collides with the physical edge of the window to before moving in the second linear movement direction, the window cleaning robot is in a path switching state where it switches between the state of moving in the first linear movement direction and the state of moving in the second linear movement direction.

[0040] First, if the liquid spraying volume per unit time of the window cleaning robot in the path switching state is greater than that in the straight-line operation state, then too much cleaning liquid will be sprayed at the physical edge of the window. On the one hand, too much cleaning liquid will flow into the gap between the physical edge of the window and the surface to be cleaned, affecting the sealing effect at this gap. Moreover, under the action of gravity, too much cleaning liquid will also flow and stay downward along the surface to be cleaned. When the window cleaning robot cleans the lower area, since the liquid spraying part will also spray cleaning liquid, at this time, there is not only the retained cleaning liquid in the lower area, but also the cleaning liquid sprayed by the liquid spraying part. The cleaning liquid not absorbed by the liquid absorbing part will easily contact the adsorbing part, affecting the adsorption effect of the window cleaning robot on the surface to be cleaned. On the other hand, since the inventory of the cleaning liquid for each single cleaning operation of the window cleaning robot is constant, if the liquid spraying volume is increased each time the window cleaning robot is in the path switching state, the cleaning liquid will be wasted, accelerating the consumption speed of the cleaning liquid, resulting in the window cleaning robot being unable to clean more areas. It is necessary to frequently add cleaning liquid to clean more areas, and the endurance ability for single cleaning is poor.

[0041] If the liquid spraying volume per unit time of the window cleaning robot in the path switching state is equal to that in the straight-line operation state, on the one hand, since the window cleaning robot will not spray more cleaning liquid when in the path switching state, it will not cause the cleaning liquid to flow into the gap between the physical edge of the window and the surface to be cleaned, affecting the sealing effect at this gap; the window cleaning robot can also effectively absorb the cleaning liquid, and will not cause too much cleaning liquid to flow downward, resulting in the problem that it is difficult to effectively clean the cleaning liquid when cleaning the lower area and weakening the adsorption effect of the adsorbing part. On the other hand, since the robot will not increase the liquid spraying volume each time it is in the path switching state, the cleaning liquid will not be exhausted faster, enabling the window cleaning robot to clean more areas. It is not necessary to frequently add cleaning liquid to clean more areas, and the endurance ability for single cleaning is better.

[0042] If the liquid spraying amount per unit time when the window cleaning robot is in the path switching state is less than the liquid spraying amount per unit time when the window cleaning robot is in the straight-line operation state, on the one hand, since less cleaning liquid is sprayed when the window cleaning robot is in the path switching state, it can ensure to a greater extent that the cleaning liquid will not flow into the gap between the window entity edge and the surface to be cleaned, affecting the sealing effect at this gap; it can ensure that the window cleaning robot absorbs the cleaning liquid more completely, and there will be no situation where the cleaning liquid is not completely absorbed by the window cleaning robot, resulting in the contact between the cleaning liquid and the suction accessory, thereby reducing the adsorption effect of the suction accessory. On the other hand, since the liquid spraying amount is reduced each time the robot is in the path switching state, more cleaning liquid is used for the window cleaning operation in the straight-line operation state, enabling the window cleaning robot to clean more areas and having better endurance for single cleaning.

[0043] If the liquid suction part stops working when the window cleaning robot is in the path switching state, it will cause the cleaning liquid sprayed by the liquid spraying part to be unable to be effectively absorbed during this process, resulting in the cleaning liquid being prone to contact with the suction accessory, weakening the adsorption effect of the suction accessory, and causing the window cleaning robot to be unable to adsorb on the surface to be cleaned, posing a risk of falling.

[0044] If the liquid suction part does not stop working when the window cleaning robot is in the path switching state, it can ensure that the liquid suction part continuously and effectively absorbs the cleaning liquid during this process, making the cleaning liquid not easy to contact with the suction accessory and ensuring the adsorption strength of the window cleaning robot during this process. Moreover, the liquid suction part can also use its negative pressure function to absorb the floating dust and fine debris near the window entity edge to improve the cleaning effect of the window cleaning robot.

[0045] Therefore, by making the second liquid spraying amount per unit time of the window cleaning robot not greater than the first liquid spraying amount per unit time, and the liquid suction part not stopping working, the cleaning liquid sprayed by the liquid spraying part can be effectively absorbed by the liquid suction part, and the cleaning liquid will not contact the suction accessory and affect its adsorption performance. At the same time, the liquid suction part can also use its negative pressure effect to absorb the floating dust and fine debris at the window entity edge, improving the cleaning effect of the window cleaning robot. Moreover, the cleaning liquid can be reasonably utilized, making the endurance of the window cleaning robot for single cleaning better. In addition, the cleaning liquid sprayed by the liquid spraying part will not affect the sealing of the gap between the window entity edge and the surface to be cleaned.

[0046] According to the fourth aspect of the present application, the present application provides a window cleaning robot, including:

[0047] A main body, the main body can adsorb on the surface to be cleaned and can move on the surface to be cleaned;

[0048] A suction accessory, the suction accessory is arranged on the main body, and the main body can be attached to the surface to be cleaned through the suction accessory; and

[0049] A cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both disposed on the main body. The liquid spraying member is capable of spraying liquid onto the surface to be cleaned, and the liquid absorbing member is capable of absorbing liquid on the surface to be cleaned through negative pressure.

[0050] In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment.

[0051] The cleaning component is configured such that during the process of the window cleaning robot moving in the first linear movement direction, the liquid absorbing member has a first average suction force; and during the process from after the window cleaning robot collides with the physical edge of the window to before moving in the second linear movement direction, at at least one position of the window cleaning robot during the above process, the suction force of the liquid absorbing member is not greater than the first average suction force.

[0052] The first linear movement direction and the second linear movement direction are opposite and parallel.

[0053] A window cleaning robot, comprising: a main body, the main body being capable of adsorbing onto the surface to be cleaned and capable of moving on the surface to be cleaned; a suction attachment, the suction attachment being disposed on the main body, and the main body being capable of attaching to the surface to be cleaned through the suction attachment; and a cleaning component, the cleaning component includes a liquid spraying member and a liquid absorbing member both disposed on the main body. The liquid spraying member is capable of spraying liquid onto the surface to be cleaned, and the liquid absorbing member is capable of absorbing liquid on the surface to be cleaned through negative pressure. In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment. These technical features correspond to the related technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, and will not be elaborated herein.

[0054] Further, it is defined that during the process of the window cleaning robot moving in the first linear movement direction, the window cleaning robot is in a linear operation state; during the process from after the window cleaning robot collides with the physical edge of the window to before moving in the second linear movement direction, the window cleaning robot is in a path switching state where it switches between the state of moving in the first linear movement direction and the state of moving in the second linear movement direction.

[0055] If the suction force of the window cleaning robot is greater than the first average suction force after it collides with the physical edge of the window and before it moves along the second straight line moving direction, that is to say, during the process of the window cleaning robot switching from the straight line moving state to the path switching state, the suction force of the liquid suction member will increase. On the one hand, the moving resistance of the window cleaning robot will also increase accordingly, which will cause the moving speed of the window cleaning robot to slow down correspondingly, prolonging the working time of the window cleaning robot, and then resulting in a lower working efficiency of the window cleaning robot. On the other hand, there are usually sundries such as feathers and leaves on the surface of the window to be cleaned. During the movement of the window cleaning robot, these sundries will be pushed to the vicinity of the physical edge of the window for the user to clean manually. If the suction force of the liquid suction member increases in the path switching state, it will absorb some of these sundries, causing the liquid suction member to be blocked, affecting its liquid absorption performance, reducing the cleaning ability of the window cleaning robot, and requiring the user to frequently clean the liquid suction member, which will also lead to a lower working efficiency of the window cleaning robot.

[0056] By making the suction force of the window cleaning robot equal to the first average suction force after it collides with the physical edge of the window and before it moves along the second straight line moving direction, that is to say, during the process of the window cleaning robot switching from the straight line moving state to the path switching state, the suction force of the liquid suction member will not change. On the one hand, the moving resistance of the window cleaning robot will not change. During this process, the moving speed of the window cleaning robot is basically constant, making the working duration of the window cleaning robot more reasonable and ensuring the working efficiency of the window cleaning robot. On the other hand, the window cleaning robot can smoothly push sundries such as feathers and leaves to the vicinity of the physical edge of the window, and when the window cleaning robot is in the path switching state, the liquid suction member will not be blocked due to inhaling these sundries, ensuring the liquid absorption performance of the liquid suction member to ensure the cleaning ability of the window cleaning robot, and the user does not need to frequently clean the liquid spraying member, thereby ensuring the working efficiency of the window cleaning robot.

[0057] Furthermore, by making the suction force of the window cleaning robot less than the first average suction force after it collides with the physical edge of the window and before it moves along the second straight line moving direction, during the process of the window cleaning robot switching from the straight line moving state to the path switching state, the suction force of the liquid suction member will decrease. On the one hand, the moving resistance of the window cleaning robot will decrease. When the window cleaning robot is in the path switching state, the moving speed of the window cleaning robot will also increase, shortening the working time of the window cleaning robot and improving the working efficiency of the window cleaning robot. Correspondingly, the window cleaning robot can also smoothly push sundries such as feathers and leaves to the vicinity of the physical edge of the window, and the liquid suction member will not be blocked due to inhaling these sundries, ensuring the liquid absorption performance of the liquid suction member to ensure the cleaning ability of the window cleaning robot, and the user does not need to frequently clean the liquid spraying member, thereby ensuring the working efficiency of the window cleaning robot.

[0058] Therefore, after the window cleaning robot collides with the physical edge of the window and before it moves along the second linear movement direction, the suction force thereof is not greater than the first average suction force, which can enable the window cleaning robot to ensure its working efficiency and even improve its working efficiency.

[0059] Optionally, according to an embodiment of the present application, the cleaning component is configured such that during the process of the window cleaning robot moving along the first linear movement direction, when the window cleaning robot is located at three positions, the liquid suction member respectively has a second suction force, a third suction force, and a fourth suction force;

[0060] The first average suction force is the average value of the sum of the second suction force, the third suction force, and the fourth suction force.

[0061] Optionally, the cleaning component is configured such that during the process of the window cleaning robot moving along the second linear movement direction, the liquid suction member has a second average suction force;

[0062] After the window cleaning robot collides with the physical edge of the window and before it moves along the second linear movement direction, when the window cleaning robot is in at least one position of the above process, the suction force of the liquid suction member is not greater than the second average suction force.

[0063] It can be understood that during the process of the window cleaning robot moving along the second linear movement direction, the window cleaning robot is also in a linear working 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 linear movement direction or the second linear movement direction, the suction force of the liquid suction member can remain relatively consistent, and thus the cleaning ability and cleaning intensity can also remain relatively consistent, so that after the window cleaning robot completes the cleaning work, there will be no stripe-shaped water stains distributed at intervals on the window, ensuring the aesthetics of the window.

[0064] Optionally, the cleaning component is configured such that during the process of the window cleaning robot moving along the second linear movement direction, when the window cleaning robot is located at three positions, the liquid suction member respectively has a fifth suction force, a sixth suction force, and a seventh suction force;

[0065] The second average suction force is the average value of the sum of the fifth suction force, the sixth suction force, and the seventh suction force.

[0066] Optionally, according to an embodiment of the present application, openings are provided at positions on the main body corresponding to the liquid spraying member and the liquid suction member, and the liquid spraying port of the liquid spraying member and the liquid suction port of the liquid suction member are both exposed through the openings.

[0067] By exposing the liquid spraying port of the liquid spraying member and the liquid suction port of the liquid suction member through an opening, so that the cleaning liquid can be sprayed out through the opening by the liquid spraying port, and the liquid can be absorbed through the opening by the liquid suction port.

[0068] There can be only one opening provided, and both the liquid spraying port of the liquid spraying member and the liquid suction port of the liquid suction member are exposed through this opening. In this way, the main body does not need to separately open two openings for the liquid spraying port and the liquid suction port respectively, making the external integrity of the main body better.

[0069] Optionally, according to an embodiment of the present 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.

[0070] In this way, the liquid suction port of the liquid suction member and the liquid spraying port of the liquid spraying member are respectively exposed through the first opening and the second opening, which can independently separate the liquid spraying port and the liquid suction port, and is more convenient for separately disassembling, assembling and maintaining one of them.

[0071] Optionally, according to an embodiment of the present application, the main body has a first surface and a second surface. The first surface faces the surface to be cleaned, and the second surface faces one of the linear movement directions;

[0072] The first opening is located on the first surface, the second opening is located on the second surface, and the liquid spraying member can spray liquid on the surface to be cleaned along one of the linear movement directions through the second opening.

[0073] In this way, the window cleaning robot sprays liquid in front of it, so that the area in front that has not been wiped by the window cleaning robot is pre-sprayed with cleaning liquid in advance, giving time for the dirt on it to fuse or react with the cleaning liquid, while the liquid suction member absorbs the cleaning liquid directly facing the surface to be cleaned.

[0074] Optionally, according to an embodiment of the present application, the main body has a first surface, and the first surface faces the surface to be cleaned;

[0075] Both the first opening and the second opening are located on the first surface.

[0076] In this way, it is more beneficial for the liquid suction member to absorb the liquid, because the area where the liquid spraying member sprays the liquid and the area where the liquid suction member absorbs the liquid are relatively close and are both located on the first surface.

[0077] Optionally, according to an embodiment of the present application, the suction force of the liquid suction member at the liquid suction port is less than the suction force of the suction member at the adsorption port.

[0078] Thus, it is possible to prevent the suction member from generating an excessive negative pressure and adsorbing to the surface to be cleaned, thereby causing additional resistance to the movement of the window cleaning robot.

[0079] Optionally, according to an embodiment of the present application, the cleaning component further includes a liquid scraping member disposed on the main body. In one of the linear movement directions of the window cleaning robot, the liquid scraping member is located between the suction member and the adsorption member, and the liquid scraping member is used for scraping liquid on the surface to be cleaned.

[0080] The liquid scraping strip contacts the surface to be cleaned when the window cleaning robot is working, thereby affecting the movement direction of the cleaning liquid. In particular, it scrapes off the cleaning liquid that is in front of the adsorption member and has not been completely sucked away by the suction member, and can make the cleaning liquid evenly distributed into a very thin cleaning liquid film on the surface to be cleaned when scraping the cleaning liquid, improving the working efficiency of subsequently wiping the surface to be cleaned by the wiping member.

[0081] Optionally, according to an embodiment of the present application, the cleaning component further includes a liquid scraping member disposed on the main body. In one of the linear movement directions of the window cleaning robot, the liquid scraping member is located between the suction member and the adsorption member, and the liquid scraping member is used for scraping liquid on the surface to be cleaned;

[0082] The liquid scraping member includes a first liquid scraping portion and a second liquid scraping portion that are spaced apart along the one linear movement direction, and the liquid suction port of the suction member is exposed between the first liquid scraping portion and the second liquid scraping portion.

[0083] Setting two liquid scraping portions can better scrape off the liquid and further prevent the excess cleaning liquid from flowing to the adsorption member. The liquid suction port of the suction member is exposed between the first liquid scraping portion and the second liquid scraping portion, so that the adsorption air flow of the suction member is not blocked by the liquid scraping portion, and it can better suck the surrounding liquid.

[0084] Optionally, according to an embodiment of the present application, at least a part of the projection of the adsorption surface of the adsorption member in the one linear movement direction falls on the liquid scraping member.

[0085] In this case, at least a part, especially all, of the cleaning liquid flowing along the one linear movement direction to the adsorption surface of the adsorption member is scraped off by the liquid scraping member. Through this arrangement, part, especially all, of the cleaning liquid flowing to the adsorption surface of the adsorption member can be first scraped off by the liquid scraping member, further preventing the cleaning liquid that may not be completely sucked by the suction member from entering the adsorption surface of the adsorption member.

[0086] Optionally, according to an embodiment of the present application, the cleaning component further includes a wiper disposed on the main body. In one of the linear movement directions of the window cleaning robot, at least a part of the wiper is located between the liquid scraping member and the suction member, and the wiper is used to wipe the surface to be cleaned.

[0087] In this way, at least a part of the wiper falls between the liquid scraping member and the suction member. This arrangement enables the cleaning liquid to flow through the wiper when flowing towards the suction member, so that the wiper can absorb the cleaning liquid flowing towards the suction member and at the same time has a sufficient wiping area in all movement directions of the window cleaning robot, and can absorb the cleaning liquid at other positions on the surface to be cleaned, so as to better wipe the surface to be cleaned through the cleaning liquid.

[0088] Optionally, according to an embodiment of the present application, the liquid spraying member includes a first nozzle and a second nozzle both disposed on the main body. The axis of the first nozzle intersects the axis of the second nozzle in one of the linear movement directions, or the liquid spraying member includes a liquid spraying pipe, and a plurality of liquid spraying holes are provided on the liquid spraying pipe, and the plurality of liquid spraying holes are spaced along the length direction of the liquid spraying pipe.

[0089] In this way, the cleaning liquid sprayed by the two nozzles can cover a larger area on the surface to be cleaned and can form a fan-shaped spraying area. In addition, it can also be arranged such that the paths of the cleaning liquid sprayed by the two nozzles intersect each other, so that the cleaning liquid sprayed by the two nozzles impacts each other, for example, falls on the surface to be cleaned in the form of mist, so as to make the cleaning liquid more evenly distributed on the surface to be cleaned.

[0090] Optionally, according to an embodiment of the present application, there are two cleaning components. In one of the linear movement directions of the window cleaning robot, the two cleaning components are respectively located on both sides of the suction member.

[0091] In one of the linear movement directions, the two cleaning components are located on both sides of the suction member, 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.

[0092] At the same time, the window cleaning work of the window cleaning robot can be more flexible. The window cleaning robot can move forward along one of the linear movement directions or move backward along one of the linear movement directions, and can perform window cleaning work. Since the window cleaning robot has two cleaning components, one in front and one behind, along one of the linear movement directions, when the window cleaning robot needs to switch the movement direction by 180° for cleaning, it does not need to turn 180° to clean, effectively reducing the switching path required for the window cleaning robot to switch the movement direction and improving the cleaning efficiency of the window cleaning robot.

[0093] Optionally, according to an embodiment of the present application, when the window cleaning robot moves along one of the linear movement directions and performs window cleaning work, the cleaning component before the suction attachment in the movement direction of the window cleaning robot is activated, and the cleaning component after the suction attachment in the movement direction of the window cleaning robot is not activated.

[0094] In this way, when the window cleaning robot moves in other directions, especially when moving in the direction opposite to the initial linear movement direction, the cleaning component after the suction attachment in the initial linear movement direction can be used for cleaning. In this way, it is always the cleaning component before the suction attachment in the movement direction of the window cleaning robot that sprays the liquid, so that the path to be wiped by the window cleaning robot has been sprayed with the cleaning liquid, rather than spraying the cleaning liquid on the path that the window cleaning robot has already passed.

[0095] Optionally, according to an embodiment of the present application, a liquid suction pump is further provided on the main body, the liquid suction pump is connected to the liquid suction member, and the liquid suction member can generate negative pressure under the drive of the liquid suction pump.

[0096] In this way, the liquid suction member can generate negative pressure through the liquid suction pump to facilitate its absorption of the cleaning liquid.

[0097] According to the fifth aspect of the present application, the present application provides a base station for a window cleaning robot. The window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid suction member both provided on the main body. In one of the linear movement directions of the window cleaning robot, at least one of the liquid suction members is located between the liquid spraying member and the suction attachment;

[0098] A liquid suction pump is provided in the base station, and the liquid suction pump is used to be connected to the liquid suction member, and the liquid suction member can generate negative pressure under the drive of the liquid suction pump.

[0099] Among them, the window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid suction member both provided on the main body.

These technical features correspond to the related technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, and will not be elaborated here.

[0100] In this way, the liquid suction pump is not arranged on the main body of the window cleaning robot, but in a base station that can be placed on the ground or on a windowsill, reducing the weight of the main body of the window cleaning robot, improving its working efficiency, and saving the energy consumption of the window cleaning robot.

[0101] According to the sixth aspect of the present application, the present application provides a base station for a window cleaning robot. The window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid suction member both provided on the main body. In one of the linear movement directions of the window cleaning robot, at least one of the liquid suction members is located between the liquid spraying member and the suction attachment.

[0102] A liquid storage chamber is provided on the base station. The liquid storage chamber is connected to the liquid spraying member through a cleaning liquid pipeline to supply liquid to the liquid spraying member, and the liquid storage chamber is connected to the liquid suction member through a contaminated liquid pipeline to recover the contaminated liquid from the liquid suction member.

[0103] Wherein, the liquid storage chamber is communicated with the contaminated liquid pipeline through a purification member.

[0104] The window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid suction member both provided on the main body.

These technical features correspond to the relevant technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, and will not be elaborated here.

[0105] By providing liquid to the window cleaning robot through the liquid storage chamber in the base station and recovering the contaminated liquid from the window cleaning robot, the entire cleaning system does not need to be externally connected to a water source or a sewage processor, improving the independence of the cleaning system.

[0106] The liquid sucked by the liquid suction member, since it has been contaminated by the dirt on the window, is first purified by the purification member and then transported back to the liquid storage chamber through the contaminated liquid pipeline, which realizes the recycling of the cleaning liquid.

[0107] According to the seventh aspect of the present application, the present application provides a base station for a window cleaning robot. The window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid suction member both provided on the main body. In one of the linear movement directions of the window cleaning robot, at least one of the liquid suction members is located between the liquid spraying member and the suction attachment.

[0108] The base station is provided with a cleaning liquid chamber and a contaminated liquid chamber. The cleaning liquid chamber is connected to the liquid spraying member through a cleaning liquid pipeline to supply liquid to the liquid spraying member, and the contaminated liquid chamber is connected to the liquid absorbing member through a contaminated liquid pipeline to recover the contaminated liquid from the liquid absorbing member.

[0109] Among them, the window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body. In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment. These technical features correspond to the related technical solutions in the first aspect of the present application, and the beneficial effects obtained are the same as those in the first aspect of the present application, which will not be elaborated herein.

[0110] By separately providing a cleaning liquid chamber and a contaminated liquid chamber, the cleaning liquid transported to the liquid spraying member and the contaminated liquid absorbed by the liquid absorbing member both have separate liquid storage chambers, which is conducive to the distinction between the two liquids and avoids the contaminated liquid from mixing into the clean cleaning liquid and contaminating it.

[0111] Optionally, according to an embodiment of the seventh aspect of the present application, the cleaning liquid chamber and the contaminated liquid chamber are connected through a purification member.

[0112] Thus, the contaminated liquid in the contaminated liquid chamber can be purified by the purification member and directly transported to the cleaning liquid chamber as cleaning liquid for use by the liquid spraying member after purification, realizing the recycling of the cleaning liquid. And due to the separate arrangement of the contaminated liquid chamber and the cleaning liquid chamber, sufficient time is left for the purification process of the liquid in the contaminated liquid chamber.

[0113] According to the eighth aspect of the present application, the present application provides a composite pipeline for connecting between a window cleaning robot and a base station. The window cleaning robot includes a main body capable of moving on a surface to be cleaned, a suction attachment provided on the main body, and a cleaning component provided on the main body. The cleaning component includes a liquid spraying member and a liquid absorbing member both provided on the main body. In one of the linear movement directions of the window cleaning robot, at least one of the liquid absorbing members is located between the liquid spraying member and the suction attachment;

[0114] The composite pipeline includes:

[0115] A cleaning liquid pipeline, which connects the base station and the liquid spraying member to transport liquid;

[0116] A contaminated liquid pipeline, which connects the liquid absorbing member and the base station to transport the contaminated liquid;

[0117] A covering pipeline that encloses the cleaning liquid pipeline and the contaminated liquid pipeline therein.

[0118] Among them, the window cleaning robot includes a main body capable of moving on the surface to be cleaned, an adsorbing component arranged on the main body, and a cleaning component arranged on the main body. The cleaning component includes a liquid spraying part and a liquid sucking part both arranged on the main body. In one of the linear moving directions of the window cleaning robot, at least one of the liquid sucking parts is located between the liquid spraying part and the adsorbing component. These technical features correspond to the related technical solutions in the first aspect of this application, and the beneficial effects obtained are the same as those in the first aspect of this application, and will not be elaborated here.

[0119] The composite pipeline includes a cleaning liquid pipeline for delivering cleaning liquid to the liquid spraying part and a contaminated liquid pipeline for recovering the contaminated liquid from the liquid sucking part, ensuring that the cleaning liquid and the contaminated liquid are respectively transported through two separate pipelines without mixing together to cause the clean cleaning liquid to be contaminated. The cleaning liquid pipeline and the contaminated liquid pipeline are enclosed by a covering pipeline into a composite pipeline, which saves the space required for wiring and also increases the strength and toughness of the pipeline.

[0120] Optionally, according to an embodiment of the eighth aspect of this application, the composite pipeline further includes a power cord for connecting the base station and the window cleaning robot to conduct power transmission. The power cord, the cleaning liquid pipeline, and the contaminated liquid pipeline are enclosed in the covering pipeline.

[0121] Thus, the window cleaning robot is powered by the base station without directly connecting to the power source itself. The power cord can also be enclosed in the covering pipeline to form a composite pipeline, protecting the power cord from being damaged due to exposure, and at the same time saving the wiring space and further increasing the strength and toughness of the composite pipeline.

[0122] 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 a pulling force for the window cleaning robot through the safety rope when the window cleaning robot falls off the surface to be cleaned. The safety rope, the cleaning liquid pipeline, and the contaminated liquid pipeline are enclosed in the covering pipeline.

[0123] The safety rope connected to the base station at one end can prevent the window cleaning robot from falling to the ground and being damaged when the window cleaning robot falls off the surface to be cleaned. The safety rope can suspend the window cleaning robot in the air when it falls off the surface to be cleaned. Enclosing the safety rope in the covering pipeline saves the storage space of the safety rope and further increases the strength and toughness of the composite pipeline.

[0124] Optionally, according to an embodiment of the eighth aspect of the present application, the base station is capable of providing a pulling force to the window cleaning robot through the covering pipeline after the window cleaning robot detaches from the surface to be cleaned.

[0125] Thus, the covering pipeline, or the composite pipeline as a whole, can be used as a safety rope to prevent the window cleaning robot from falling to the ground and being damaged when detaching from the surface to be cleaned, enabling it to withstand a greater pulling force from the window cleaning robot and further reducing the risk of the window cleaning robot falling to the ground.

[0168] It is easy to understand that according to the technical solution of this application, under the condition of not changing the essential spirit of this application, those of ordinary skill in the art can propose various interchangeable structural manners and implementation manners. Therefore, the following detailed implementation manners and accompanying drawings are only exemplary descriptions of the technical solution of this application, and should not be regarded as the whole of this application or as a limitation or restriction on the technical solution of this application.

[0169] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, and thus may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for descriptive and differentiating purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components or the sequence of the components or the assembly sequence.

[0170] In the related art, a window cleaning robot is a device that can move on a window and clean the surface to be cleaned of the window during the movement.

[0171] Window cleaning robots are usually equipped with suction cups, walking wheels, nozzles and cleaning rags. The window cleaning robot adsorbs on the surface to be cleaned through the suction cup and moves on the surface to be cleaned through the walking wheels. At the same time, the nozzle can spray liquid on the surface to be cleaned, and then the cleaning rag wipes the surface to be cleaned.

[0172] However, the absorption capacity of the cleaning rag for the cleaning liquid is limited. As the cleaning work continues, the water absorption capacity of the cleaning rag will gradually weaken, and even it cannot absorb the cleaning liquid, resulting in the cleaning liquid flowing to the periphery of the suction cup or entering the adsorption cavity of the suction cup, making it difficult for the window cleaning robot to maintain the state of adsorbing on the surface to be cleaned, increasing the risk of the window cleaning robot falling from the surface to be cleaned. Therefore, it is necessary to frequently replace the cleaning rag to ensure the continuous operation of the window cleaning robot, resulting in low working efficiency of the window cleaning robot and poor user experience.

[0173] Moreover, affected by the limited liquid absorption capacity of the cleaning cloth, the liquid spraying member can only clean by spraying liquid at intervals to ensure that the window cleaning robot can work for a long time. However, the cleaning effect of this cleaning method is poor, and it is difficult to deal with a relatively dirty surface to be cleaned. It can only clean the surface to be cleaned multiple times, which also results in low working efficiency of the window cleaning robot and poor user experience.

[0174] In summary, the window cleaning robot in the related technology has technical problems of poor cleaning effect and low working efficiency.

[0175] This application proposes a window cleaning robot with good cleaning effect and high working efficiency. Refer to Figure 1 , which shows a schematic bottom structure diagram of the window cleaning robot 10 facing the surface to be cleaned according to an embodiment of the present application. The window cleaning robot 10 includes a main body 100, an adsorption member 200, and a cleaning component 300. The adsorption member 200 and the cleaning component 300 are both arranged on the main body 100. For the convenience 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 forming an angle with the surface to be cleaned is defined as the "side surface". In addition, it should be understood that the "front" or "back" of the window cleaning robot 10 in the following description is the front or back relative to the moving direction of the window cleaning robot 10.

[0176] The main body 100 can be adsorbed on the surface to be cleaned and can move on the surface to be cleaned. The main body 100 can be adsorbed on the surface to be cleaned through the adsorption member 200. The main body 100 can be provided with traveling wheels or a traveling track 400 to move on the surface to be cleaned through the traveling wheels or the traveling track 400, and then drive the cleaning component 300 to move to different positions on the surface to be cleaned. In this way, the cleaning component 300 can clean different positions on the surface to be cleaned. In the following description, the linear moving direction of the window cleaning robot 10 can be the Figure 1 length direction of the traveling track 400 of the window cleaning robot 10 as shown.

[0177] For example, refer to Figure 6 , Figure 6 is a schematic diagram of the window cleaning robot 10 moving in the first linear moving direction; refer to Figure 7 , Figure 7 is a schematic diagram of the window cleaning robot 10 moving during the process from after colliding with the physical edge of the window to before moving in the second linear moving direction; refer to Figure 8 , Figure 8 is a schematic diagram of moving in the second linear moving direction.

[0178] The linear moving direction can be Figure 6 , Figure 7 or Figure 8The moving direction of the window cleaning robot shown in the figure.

[0179] Among them, the suction attachment 200 can be a suction cup. Of course, the suction attachment 200 can also be other components that adsorb on the surface to be cleaned through negative pressure, and no specific limitation is made here.

[0180] The suction attachment 200 adsorbs on the surface to be cleaned through negative pressure. It can be understood that the adsorption effect of the suction attachment 200 will not affect the movement of the window cleaning robot on the surface to be cleaned (such as movement parallel to the surface to be cleaned) through the traveling wheels or the traveling track 400. The suction attachment 200 can be arranged at the central position of the bottom surface of the main body 100.

[0181] The cleaning component 300 includes a liquid spraying part 310 and a liquid absorbing part 320 both arranged on the main body 100. The liquid spraying part 310 can spray liquid onto the surface to be cleaned, and the liquid absorbing part 320 can absorb liquid on the surface to be cleaned through negative pressure. In one of the linear moving directions of the window cleaning robot 10, the liquid absorbing part 320 is located between the liquid spraying part 310 and the suction attachment 200. For example, in the first linear moving direction of the window cleaning robot 10, the liquid absorbing part 320 is located between the liquid spraying part 310 and the suction attachment 200.

[0182] On the one hand, the liquid absorbing part 320 can absorb the cleaning liquid on the surface to be cleaned. In this way, before the cleaning liquid on the surface to be cleaned contacts the adsorption surface of the suction attachment 200, the cleaning liquid will be absorbed by the liquid absorbing part 320 to prevent the cleaning liquid from contacting the adsorption surface of the suction attachment 200 and flowing into the adsorption cavity of the suction attachment 200, reducing the adsorption effect of the suction attachment 200 on the surface to be cleaned.

[0183] On the other hand, the liquid absorbing part 320 can not only adsorb the cleaning liquid, but also use its negative pressure to absorb other liquids, floating dust and fine 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 absorbing part can also absorb liquids such as rainwater and dirty water, floating dust and fine debris remaining on the surface to be cleaned.

[0184] On the other hand, the liquid absorbing part 320 can also achieve self-cleaning by using the cleaning liquid to improve the utilization rate of the cleaning liquid. Specifically, when the liquid absorbing part 320 absorbs the cleaning liquid, the cleaning liquid will flow on the inner wall of the liquid absorption cavity of the liquid absorbing part 320 to clean the inner wall of the liquid absorption cavity. In this way, the self-cleaning of the liquid absorbing part 320 can be achieved.

[0185] In an embodiment of the present application, the distance between the at least one liquid absorbing part and the liquid spraying part is greater than or equal to 1 cm and less than or equal to 6 cm.

[0186] In an embodiment of the present application, the cleaning component 300 is configured such that when the window cleaning robot 10 moves in the first linear movement direction, the liquid spraying member 310 has a first liquid spraying volume per unit time; when the window cleaning robot 10 collides with the physical edge 6 of the window and before moving in the second linear movement direction, the liquid spraying member 310 has a second liquid spraying volume per unit time, and the liquid absorbing member 320 does not stop working; wherein, the second liquid spraying volume per unit time is not greater than the first liquid spraying volume per unit time. The window cleaning robot 10 can control the liquid spraying pump of the liquid spraying member 310 to adjust the liquid spraying volume of the liquid spraying member 310 according to the above different movement states.

[0187] In another embodiment of the present application, the cleaning component 300 is configured such that during the process of the window cleaning robot 10 moving in the first linear movement direction, the liquid absorbing member 320 has a first average suction force; and during the process after the window cleaning robot 10 collides with the physical edge 6 of the window and before moving in the second linear movement direction, at at least one position during the above process, the suction force of the liquid absorbing 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.

[0188] Specifically, the cleaning component 300 is configured such that during the process of the window cleaning robot 10 moving in the first linear movement direction, when the window cleaning robot 10 is located at three positions, the liquid absorbing member 320 has a second suction force, a third suction force, and a fourth suction force respectively; 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.

[0189] In an embodiment of the present application, the cleaning component 300 is configured such that during the process of the window cleaning robot 10 moving in the second linear movement direction, the liquid absorbing member 320 has a second average suction force; during the process after the window cleaning robot 10 collides with the physical edge 6 of the window and before moving in the second linear movement direction, at at least one position during the above process, the suction force of the liquid absorbing member 320 is not greater than the second average suction force, and the second average suction force may be equal to the first average suction force.

[0190] Specifically, the cleaning component 300 is configured such that during the process of the window cleaning robot 10 moving in the second linear movement direction, when the window cleaning robot 10 is located at three positions, the liquid absorbing member 320 has a fifth suction force, a sixth suction force, and a seventh suction force respectively; 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.

[0191] In an embodiment of the present application, for example Figure 1In an embodiment, an opening 110 is provided at a position on the host 100 corresponding to the liquid spraying member 310 and the liquid absorbing member 320. The liquid spraying port of the liquid spraying member 310 and the liquid absorbing port of the liquid absorbing member 320 are both exposed through the opening 110. Refer to Figure 2 , which shows a schematic bottom view of the window cleaning robot 10 facing the surface to be cleaned 5 according to another embodiment of the present application. In Figure 2 the embodiment, the opening 110 includes independent first and second openings. The liquid absorbing port of the liquid absorbing member 320 is exposed through the first opening, and the liquid spraying port of the liquid spraying member 310 is exposed through the second opening. The host 100 has a first surface and a second surface. The first surface faces the surface to be cleaned 5, that is, the above-mentioned 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 (since the second opening is located on the second surface, it is not clearly shown in Figure 2 ). The liquid spraying member 310 can spray liquid on the surface to be cleaned 5 along one of the linear movement directions (taking the first linear movement direction as an example) through the second opening. In another embodiment of the present application, it can also be arranged that the host 100 has a first surface, and the first surface faces the surface to be cleaned 5; both the first opening and the second opening are located on the first surface. In this embodiment, the liquid spraying member 310 sprays liquid towards the surface to be cleaned 5, and the liquid absorbing member 320 also absorbs the cleaning liquid towards the surface to be cleaned 5.

[0192] In an embodiment of the present application, the suction force at the liquid absorbing port of the liquid absorbing member 320 is less than the suction force at the adsorption port of the adsorbing member 200.

[0193] In an embodiment of the present application, the cleaning assembly 300 further includes a liquid scraping member 330 provided on the host. In one of the linear movement directions of the window cleaning robot 10 (taking the first linear movement direction as an example), the liquid scraping member 330 is located between the liquid absorbing member 320 and the adsorbing member 200 to scrape the liquid on the surface to be cleaned 5. The liquid scraping member 330 is, for example, a long strip-shaped liquid scraping bar, which extends transversely to one of the linear movement directions (taking the first linear movement direction as an example) on the bottom surface of the window cleaning robot 10. The liquid scraping member 330, for example, includes a first liquid scraping portion and a second liquid scraping portion arranged at intervals along one of the linear movement directions (taking the first linear movement direction as an example). The first liquid scraping portion and the second liquid scraping portion are, for example, both arranged as liquid scraping bars extending perpendicular to the one of the linear movement directions (taking the first linear movement direction as an example).

[0194] In an embodiment of the present application, the projection of the adsorption surface of the adsorbing member 200 in one of the linear movement directions (taking the first linear movement direction as an example) at least partially, especially completely, falls on the liquid scraping member 330.

[0195] In an embodiment of the present application, the cleaning component 300 further includes a wiping member 340 disposed on the main body. Along one of the linear movement directions of the window cleaning robot 10 (taking the first linear movement direction as an example), at least a part of the wiping member 340 is located between the liquid scraping member 330 and the suction member 200 to wipe the surface 5 to be cleaned. The wiping member 340 is, for example, a soft material such as a rag or a sponge that can absorb water and is used for wiping.

[0196] In an embodiment of the present application (not shown in the drawings), the liquid spraying member 310 includes a first nozzle and a second nozzle both disposed on the main body 100. The axis of the first nozzle intersects with the axis of the second nozzle along one of the linear movement directions (taking the first linear movement direction as an example). It should be understood that the liquid spraying member 310 may of course also include one or more than two nozzles. In an embodiment of the present application, the liquid spraying member 310 may further include a liquid spraying pipe, and a plurality of liquid spraying holes 311 are provided on the liquid spraying pipe, and the plurality of liquid spraying holes 311 are spaced apart along the length direction of the liquid spraying pipe.

[0197] In an embodiment of the present application, the window cleaning robot 10 includes two cleaning components. Along one of the linear movement directions (taking the first linear movement direction as an example), the two cleaning components are located on both sides of the suction member 200, that is, the window cleaning robot has two cleaning components, one in front and one behind, along one of the linear movement directions (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. Further, when the window cleaning robot 10 moves along one of the linear movement directions (taking the first linear movement direction as an example) to perform window cleaning work, the cleaning component before the suction member 200 along the movement direction of the window cleaning robot 10 is activated, and the cleaning component after the suction member 200 along the movement direction of the window cleaning robot 10 is not activated.

[0198] In an embodiment of the present application, the window cleaning robot 10 includes a liquid suction pump disposed on the main body 100. The liquid suction pump is connected to the liquid suction member, and the liquid suction member can generate a negative pressure under the drive of the liquid suction pump.

[0199] On the other hand, the present application proposes a base station 20 for the above-mentioned window cleaning robot. Refer to Figure 3 , which shows a schematic structural diagram of the base station 20 proposed according to an embodiment of the present application. A liquid suction pump (not specifically shown in Figure 3 ) is provided in the base station 20. The liquid suction pump is used to be connected to the liquid suction member 320, and the liquid suction member 320 can generate a negative pressure under the drive of the liquid suction pump.

[0200] In an embodiment of another aspect of the present application, a liquid storage chamber 21 is provided on the base station 20. The liquid storage chamber 21 is connected to the liquid spraying member 310 through a cleaning liquid pipeline 301 to supply liquid to the liquid spraying member 310, and the liquid storage chamber 21 is connected to the liquid absorbing member 320 through a contaminated liquid pipeline 302 to recover the contaminated liquid from the liquid absorbing member 320. Among them, the liquid storage chamber 21 communicates with the contaminated liquid pipeline 302 through a purification member. In this embodiment, the cleaning liquid stored in the liquid storage chamber 21 can be sprayed onto the surface 5 to be cleaned through the liquid spraying member 310. The liquid absorbed by the liquid absorbing member 320, since it has been contaminated by the dirt on the window, is first purified by the purification member and then transported back to the liquid storage chamber 21 through the contaminated liquid pipeline 302, which realizes the recycling of the cleaning liquid. The purification member is, for example, a filter, a water purifier, or a combination of a filter and a water purifier, etc.

[0201] In an embodiment of another aspect of the present application, the base station 20 is separately provided with a cleaning liquid chamber 211 and a contaminated liquid chamber 212. The cleaning liquid chamber 211 is connected to the liquid spraying member 310 through a cleaning liquid pipeline 301 to supply liquid to the liquid spraying member 310, and the contaminated liquid chamber 212 is connected to the liquid absorbing member 320 through a contaminated liquid pipeline 302 to recover the contaminated liquid from the liquid absorbing member 320. In this embodiment, the cleaning liquid for supplying to the liquid spraying member 310 and the contaminated liquid absorbed from the liquid absorbing member 32 are stored in a chamber respectively. The cleaning liquid chamber 211 and the contaminated liquid chamber 212 are, for example, connected through a purification member, so that the contaminated liquid in the contaminated liquid chamber 212 can flow into the cleaning liquid chamber 211 after being purified by the purification member, providing more time for the purification or filtration from the contaminated liquid to the cleaning liquid, and finally realizing the recycling of the cleaning liquid. The purification member is, for example, a filter, a water purifier, or a combination of a filter and a water purifier, etc.

[0202] The present application also proposes a composite pipeline 30, which is used to connect between the window cleaning robot 10 and the base station 20 described above.

[0205] A covering pipeline 303, which covers the cleaning liquid pipeline 301 and the contaminated liquid pipeline 302 therein.

[0206] The composite pipeline 30 is an integrated pipeline, which integrates multiple pipelines such as the cleaning liquid pipeline 301 and the dirty liquid pipeline 302 into a single line by covering the pipeline 303, saving wiring space and also improving the strength and toughness of the composite pipeline 30 itself.

[0207] In one embodiment, the composite pipeline 30 further includes a power cord 304 for connecting the base station 20 and the window cleaning robot 10 to transmit electric energy. The power cord 304, the cleaning liquid pipeline 301 and the dirty liquid pipeline 302 are covered in the covering pipeline 303. The power cord 304, for example, includes two positive and negative lines as shown in Figure 4 . When the window cleaning robot 10 is connected to the base station 20 through the power cord 304, the power supply of the window cleaning robot 10 can be directly through the power supply in the base station or through an external power supply of the base station.

[0208] In one embodiment, the composite pipeline 30 further includes a safety rope 305 connecting the base station 20 and the window cleaning robot 10. When the window cleaning robot 10 falls off the surface 5 to be cleaned, the base station 20 can provide a pulling force for the window cleaning robot 10 through the safety rope 305, so that the window cleaning robot 10 can be suspended in the air by the safety rope 305 connected to the base station 20 at one end when it falls, rather than directly falling to the ground, preventing the window cleaning robot 10 from being damaged by collision. The safety rope 305, the cleaning liquid pipeline 301 and the dirty liquid pipeline 302 are covered in the covering pipeline 303. The composite pipeline 30 can also include the power cord 304 and the safety rope 305 at the same time, as shown in Figure 4 . The power cord 304, the safety rope 305, the cleaning liquid pipeline 301 and the dirty liquid pipeline 302 are all covered in the covering pipeline 303. In addition, it should be understood that especially when the safety rope 305 is covered in the covering pipeline 303 and forms a part of the composite pipeline 30, the covering pipeline 303, or the composite pipeline 30 as a whole, can also act as the safety rope 305 to provide a pulling force for the fallen window cleaning robot 10 and prevent it from falling to the ground.

[0209] This application also proposes a window cleaning system 1. Referring to Figure 5 , which shows a schematic diagram of the window cleaning system 1 proposed according to an embodiment of this application.
