[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] Unless otherwise defined, technical or scientific terms used in this disclosure should have the ordinary meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are simply used to distinguish different components. The words "include" or "comprising" and similar terms mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0032] The features such as "perpendicular", "parallel" and "same" used in this disclosure include the features such as "perpendicular", "parallel" and "same" in the strict sense, as well as the cases where "approximately perpendicular", "approximately parallel" and "approximately the same" include certain errors, taking into account the errors associated with the measurement and the measurement of specific quantities (that is, the limitations of the measurement system), and are expressed as being within the acceptable deviation range for a specific value determined by a person of ordinary skill in the art. The "center" in the embodiments of the present disclosure can include a position strictly at the geometric center and a position approximately at the center of a small area around the geometric center. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of the value.

[0033] Cleaning robots can save time and energy, improve cleaning efficiency, and enhance indoor air quality, making living and working environments more comfortable. For example, window cleaning machines, which utilize mechanical equipment to clean windows, play a vital role in modern high-rise buildings. The sealing method of window cleaning machines is crucial for ensuring their cleaning effectiveness and safety.

[0034] Some window cleaning machines employing an airtight seal feature seals around the machine or in areas where it contacts the window surface, sealing any irregular gaps between the window and the machine. Furthermore, window cleaning machines may incorporate features that generate suction forces, such as suction cups, to ensure the machine remains firmly attached to the window surface, enabling stable and safe movement across the surface during operation.

[0035] During the study, the inventors of the present disclosure found that some window cleaning machines that achieve sealing through non-contact hard seals have a large amount of air leakage due to the clearance fit method, and the fitting accuracy requirements are high. In addition, the deformation of the bracket used to install the rag is also prone to air leakage, causing the window cleaning machine to fall. Some window cleaning machines achieve sealing through end sealing, that is, the two end faces of the seal in the thickness direction of the window cleaning machine are respectively abutted against the other structural end faces of the window cleaning machine. The window cleaning machine that achieves sealing through end sealing has a short service life of the seal and is prone to causing leakage of the suction cup. In addition, during the operation of the window cleaning machine, when wiping larger particles of stains, the running wheels of the window cleaning machine will be lifted up by the stains, and the rebound of the seal will be difficult to keep up in time, which will also cause leakage of the suction cup, causing the window cleaning machine to fall.

[0036] At least one embodiment of the present disclosure provides a cleaning component, comprising: a first module and a second module, which are arranged opposite to each other in a first direction; and a first elastic sealing structure; wherein the first module includes a first protruding part protruding toward the second module, and the second module includes a second protruding part protruding toward the first module; the first elastic sealing structure is arranged between side surfaces of the first protruding part and the second protruding part facing each other along the second direction to seal the gap between the first protruding part and the second protruding part in the second direction; the second direction intersects with the first direction.

[0037] At least one embodiment of the present disclosure provides a cleaning device including the above-mentioned cleaning component.

[0038] At least one embodiment of the present disclosure provides a cleaning assembly and a cleaning device, wherein a first protruding part of the first module and a second protruding part of the second module form a gap between the side surfaces facing each other in the second direction, and by arranging a first elastic sealing structure at the gap, the cleaning assembly can be sealed by side sealing. Since the first elastic sealing structure is sealed by side sealing, the first elastic sealing structure is subjected to force in the lateral direction, thereby extending the service life of the first elastic sealing structure. Moreover, when the first module and the second module undergo relative movement during operation, the force acting on the surface of the first elastic sealing structure where the sealing is achieved is a frictional force, thereby preventing sealing failure caused by insufficient rebound speed after the elastic deformation of the first elastic sealing structure.

[0039] The cleaning assembly and the cleaning device are described below with reference to the accompanying drawings and through some embodiments.

[0040] Figure 1 is a partial schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure. Figure 2 is a schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure.

[0041] 1 and 2 , at least one embodiment of the present disclosure provides a cleaning assembly, which may include a first module 100, a second module 200, and a first elastic sealing structure 300. For example, the cleaning assembly may be used to clean a surface 10 to be cleaned. For example, the surface 10 to be cleaned may be a glass surface of a window, a wall, a floor, or other surface to be cleaned. For example, the first module 100 may include a housing and a control module (not shown in the figure) of the cleaning assembly. For example, the second module 200 may include a bracket 220 and a wiping member 230 mounted on the bracket 220. For example, the wiping member 230 may be a dry rag or a wet rag. For example, the material of the first elastic sealing structure 300 may include at least one of silicone, rubber, and plastic. For example, the material of the first elastic sealing structure 300 may be foam. For example, the cleaning assembly may further include a walking component 500, which enables the movement of the cleaning assembly relative to the surface 10 to be cleaned. For example, the walking component 500 can be arranged on a side surface of the second module 200 away from the first module 100, so that when the cleaning assembly cleans the surface 10 to be cleaned, the walking component 500 contacts the surface 10 to be cleaned to achieve movement of the cleaning assembly. For example, the walking component 500 can be a running wheel or a crawler track. For example, the cleaning assembly can also include a drive module, which can be electrically connected to the control module and configured to drive the walking component 500 to move. For example, the drive module can drive the walking component 500 to move in response to a control signal from the control module.

[0042] As shown in Figures 1 and 2, the first module 100 and the second module 200 can be arranged relative to each other in a first direction Y. The first module 100 can include a first protruding member 110 protruding toward the second module 200, and the second module 200 can include a second protruding member 210 protruding toward the first module 100. For example, during operation of the cleaning assembly, the first direction Y can be a direction intersecting the surface to be cleaned 10. For example, the first direction Y can be a direction perpendicular to the surface to be wiped. For example, the first protruding member 110 can protrude along the first direction Y toward the second module 200, and the second protruding member 210 can protrude along the first direction Y toward the first module 100.

[0043] As shown in Figures 1 and 2, the first elastic sealing structure 300 is disposed between the facing side surfaces of the first and second protruding members 110, 210 along the second direction X to seal the gap 101 between the first and second protruding members 110, 210 in the second direction X, where the second direction X intersects the first direction Y. For example, the second direction X can be perpendicular to the first direction Y. For example, the extension direction of the first and second protruding members 110 and 210 can be parallel. Of course, the extension direction of the first and second protruding members can also intersect the first direction, as long as the gap 101 can be formed in the second direction by the first and second protruding members. For example, the first elastic sealing structure 300 can be pre-compressed between the first and second protruding members 110, 210 in the second direction X.

[0044] For example, referring to FIG1 , a portion of the first elastic sealing structure 300 may have a generally rectangular cross-sectional shape, and the first elastic sealing structure 300 may be sandwiched between the first protruding member 110 and the second protruding member 210. For example, referring to FIG2 , a portion of the first elastic sealing structure 300 may have a generally I-shaped cross-sectional shape. For example, the first elastic sealing structure 300 may be sleeved onto the second protruding member 210. Of course, the first elastic sealing structure may also be sleeved onto the first protruding member, and this disclosure is not limited thereto.

[0045] In at least one embodiment of the present disclosure, a cleaning assembly is provided in which a gap 101 is formed between the side surfaces of the first protruding member 110 of the first module 100 and the second protruding member 210 of the second module 200 facing each other in the second direction X. By disposing a first elastic sealing structure 300 at the gap 101, the cleaning assembly can be sealed by a side seal. Because the first elastic sealing structure 300 is sealed by a side seal, the first elastic sealing structure 300 is subjected to lateral force, thereby extending the service life of the first elastic sealing structure 300.

[0046] When the cleaning assembly is not in operation, it can be placed on the ground, and the first direction Y can be perpendicular to the ground. In a cleaning assembly using an end-sealing method, the first elastic sealing structure will be subject to gravity and pressure from the structure above. The first elastic sealing structure will continue to be subjected to a large force when in the placed state, which weakens the rebound force of the first elastic sealing structure and causes the problem of decreased elasticity. Referring to Figure 1, in the cleaning assembly of the embodiment of the present disclosure, the surface on which the first elastic sealing structure 300 achieves sealing is the side surface in the second direction X. When not in operation, the first elastic sealing structure 300 is subjected to very little extrusion force in its lateral direction, thereby extending the service life of the first elastic sealing structure 300.

[0047] Moreover, when the first module 100 and the second module 200 undergo relative movement during operation (for example, the direction of relative movement is the first direction Y), the force acting on the surface of the first elastic sealing structure 300 where the seal is achieved is a friction force (for example, the friction force between the side surface of the first elastic sealing structure 300 and the side surface of the first module 100), and the direction of the friction force is parallel to the side surface. Even if the first elastic sealing structure 300 undergoes elastic deformation, the two side surfaces of the seal (for example, the side surface of the first elastic sealing structure 300 and the side surface of the first module 100) will not separate from each other, thereby preventing sealing failure caused by insufficient rebound speed after the first elastic sealing structure 300 undergoes elastic deformation.

[0048] Figure 3A is a schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure. Figure 3B is a partially enlarged view of point A in Figure 3A. The cleaning assembly shown in Figure 3A differs from the cleaning assembly shown in Figure 2 in that the first elastic sealing structure 300 in Figure 3A is different from the first elastic sealing structure 300 in Figure 2.

[0049] Referring to Figures 3A and 3B , in some examples, at least a portion of the first elastic sealing structure 300 has a dimension in the third direction V that is greater than or equal to the dimension of the gap 101 in the second direction X. This allows the first elastic sealing structure 300 to seal the gap 101 by elastically deforming when subjected to an external force. A plane perpendicular to the first direction Y is a reference plane, and the third direction V intersects the reference plane. For example, the third direction V intersects the first direction Y and the second direction X. For example, referring to Figure 2 , when the first module 100 and the second module 200 undergo relative motion, the first elastic sealing structure 300 can elastically deform due to friction in the first direction Y, thereby enabling the first elastic sealing structure 300 to better seal the gap 101 in the second direction X. For example, referring to Figure 3A , when the cleaning assembly is attached to the surface 10 to be cleaned (e.g., when the cleaning assembly is attached to a window), the air pressure outside the cleaning assembly is greater than the air pressure inside the first elastic sealing structure 300. 3B , the imbalance in air pressure between the inside and outside creates an airflow s flowing from the outside in. When airflow s flows toward the first elastic sealing structure 300 , it applies force to the first elastic sealing structure 300 , causing it to elastically deform, thereby sealing the gap 101 and achieving a seal.

[0050] 3A and 3B , in some examples, at least a portion of the first elastic sealing structure 300 is configured to be deformable so as to come into close contact with the first protruding member 110 and the second protruding member 210, respectively, to seal the gap 101. For example, a portion of the first elastic sealing structure 300 can be elastically deformed when subjected to an external force, and the deformed portion can abut against one of the first protruding member 110 and the second protruding member 210, while the remaining portion of the first elastic sealing structure 300 can abut against the other of the first protruding member 110 and the second protruding member 210, thereby sealing the gap 101.

[0051] Referring to Figures 3A and 3B , in some examples, the first elastic sealing structure 300 may include a connecting portion 310 and a sealing portion 320. For example, the connecting portion 310 and the sealing portion 320 may be integrally formed. The connecting portion 310 may be connected to one of the first protruding member 110 and the second protruding member 210. For example, the connecting portion 310 may be bonded to the second protruding member 210. For example, other fixing structures may be provided between the connecting portion 310 and the second protruding member 210 to securely secure the connecting portion 310 to the second protruding member 210. For example, the connecting portion 310 may also be fixed to other structures of the second module 200, and this disclosure is not limited thereto.

[0052] Figure 4 is a schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure. Figure 5 is a schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure. The cleaning assemblies shown in Figures 4 and 5 differ from the cleaning assembly shown in Figure 2 in that the first elastic sealing structure in Figures 4 and 5 is different from the first elastic sealing structure in Figure 2.

[0053] Referring to FIG4 , the connecting portion 310 can be sleeved onto the second protruding member 210, and the sealing portion 320 can be located outside the connecting portion 310. By sleeved onto the second protruding member 210, the sealing portion 320 can be extended toward the first protruding member 110, thereby allowing the sealing portion 320 to deform and form close contact with the first protruding member 110. Referring to FIG5 , the connecting portion 310 can be nested between two adjacent first protruding members 110, and the sealing portion 320 can be located inside the connecting portion 310. By nesting the connecting portion 310 between two adjacent first protruding members 110, the sealing portion 320 can be extended toward the second protruding member 210, thereby allowing the sealing portion 320 to deform and form close contact with the second protruding member 210. For example, the cross-sectional shape of the connecting portion 310 can be substantially I-shaped. Of course, the cross-sectional shape of the connecting portion 310 can also be other shapes, and this disclosure is not limited thereto.

[0054] Referring to Figures 3A and 3B , the sealing portion 320 includes a fixed end 321 and a free end 322 disposed opposite each other in a third direction V. The fixed end 321 is connected to the connecting portion 310, and the free end 322 is configured to deform to closely contact the other of the first module 100 and the second module 200. For example, the sealing portion 320 may be disposed toward the first protruding member 110. For example, the free end 322 of the sealing portion 320 may deform when subjected to an external force, thereby closely contacting the first protruding member 110. For example, the sealing portion may be fixed to the connecting portion via the fixed end. When subjected to an external force, the sealing portion may rotate about the fixed end, causing the entire sealing portion to deform from extending in the third direction to extending in the second direction, thereby sealing the gap. For example, only the free end of the sealing portion may deform, causing the free end to abut against the first protruding member, thereby sealing the gap.

[0055] 3A and 3B , in some examples, the cleaning assembly includes an adsorption chamber 410. For example, the cleaning assembly can be adsorbed on the surface to be cleaned 10 through the adsorption chamber 410. An air guide chamber 420 is formed between the first protruding part 110 and the second protruding part 210. For example, the gap 101 is located in the air guide chamber 420. The first protruding part 110 of the first protruding part 110 and the second protruding part 210 is located on the outside, and an opening 430 is provided between the end of the first protruding part 110 and the second module 200. The opening 430 connects the air guide chamber 420 with the external space. For example, the side close to the adsorption chamber 410 is the inner side of the cleaning assembly, and the side away from the adsorption chamber 410 is the outer side of the cleaning assembly. The sealing portion 320 is located in the air guide chamber 420, and the free end 322 is arranged closer to the opening 430 than the fixed end 321. For example, referring to Figures 3A and 3B, taking the first protruding part 110 and the second protruding part 210 located on both sides of the first elastic sealing structure 300 as an example, the first protruding part 110 is located on the outside of the second protruding part 210, and the opening 430 is provided between the first protruding part 110 and the second module 200. The airflow s flows from the external space to the adsorption chamber 410 through the opening 430. The first elastic sealing structure 300 blocks the flow path of the airflow s, so that the sealing part 320 is deformed when it is subjected to the force of the airflow s, so that the sealing part 320 blocks the gap 101.

[0056] For example, the second protruding member of the first and second protruding members may be located on the outside, and an opening may be provided between the end of the second protruding member and the first module. In this case, the sealing method of the first elastic sealing structure may refer to the above example, and this disclosure will not elaborate on this.

[0057] 3A and 3B , in the sealing portion 320 extending along the third direction V, the free end 322 is positioned closer to the opening 430 than the fixed end 321. When airflow s applies force to the sealing portion 320, an angle is formed between the extending direction of the sealing portion 320 and the direction of the airflow s. When the sealing portion 320 deforms due to the force of the airflow s, the free end 322 tends to deform toward the side away from the connecting portion 310, with the fixed end 321 as the center of rotation, thereby sealing the gap 101.

[0058] In some examples, the cleaning assembly includes an initial state and an adsorption state. For example, the initial state is the state of the cleaning assembly when not in operation, and the adsorption state is the state of the cleaning assembly when in operation. In the initial state, the first elastic sealing structure 300 has a clearance fit with at least one of the first protruding member 110 and the second protruding member 210. For example, referring to Figures 3A and 3B, the first elastic sealing structure 300 is fixed to the second protruding member 210 and has a clearance fit with the first protruding member 110 to facilitate installation of the first elastic sealing structure 300. For example, the connecting portion 310 of the first elastic sealing structure 300 may have a clearance with the first protruding member 110. For example, the free end 322 of the sealing portion 320 in the first elastic sealing structure 300 may have a clearance with the first protruding member 110. For example, after the sealing portion 320 is deformed, the free end 322 may transition from a clearance fit to an interference fit with the first protruding member 110, thereby achieving a seal. For example, referring to Figures 1 and 2, the first elastic sealing structure 300 abuts against at least one of the first protruding part 110 and the second protruding part 210, so that the first elastic sealing structure 300 can always abut between the first protruding part 110 and the second protruding part 210, and further improve the sealing effect after deformation occurs.

[0059] For example, referring to Figures 3A and 3B, when the cleaning component is in the adsorption state, the pressure in the adsorption chamber 410 is lower than the pressure in the external space. For example, by setting the pressure in the adsorption chamber 410 to be lower, the cleaning component can be reliably adsorbed on the surface to be cleaned 10 under the action of atmospheric pressure. The free end 322 is configured to be moved in a direction away from the opening 430 under pressure until the first elastic sealing structure 300 is in close contact with the first protruding part 110 and the second protruding part 210, respectively, to seal the gap 101. Through the pressure difference between the adsorption chamber 410 and the external space, the airflow s flowing from the external space to the adsorption chamber 410 can be utilized, and the force generated by the flow of the airflow s drives the first elastic sealing structure 300 to deform.

[0060] In some examples, referring to Figures 3A and 3B, the first module 100 includes a shell and an adsorption module (not shown in the figures) disposed in the shell. For example, the adsorption module can be a fan. For example, the air in the adsorption chamber 410 can be extracted by the rotation of the fan, so that the cleaning component is adsorbed on the surface to be cleaned 10. The first protruding part 110 is provided on the side of the shell facing the second module 200. For example, the first protruding part 110 and the shell can be an integral structure. When the cleaning component is in the adsorption state, the adsorption module is configured to be able to suck the gas in the adsorption chamber 410 to provide negative pressure to the adsorption chamber 410, so that the cleaning component can be adsorbed on the surface to be cleaned 10 during operation and perform cleaning.

[0061] In some examples, referring to Figures 3A and 3B , the dimension of the fixed end 321 in the first direction Y is greater than the dimension of the free end 322 in the first direction Y. This increases the thickness of the fixed end 321, thereby strengthening the connection between the fixed end 321 and the connecting portion 310 and extending the service life of the first elastic sealing structure 300. Furthermore, the free end 322 is thinner and more sensitive. When the force generated by the airflow s is relatively low, the free end 322 of the sealing portion 320 can easily deform, increasing the response speed of the first elastic sealing structure 300 and thereby sealing the gap 101 more quickly. As a result, during operation, the cleaning assembly can more quickly and securely adhere to the surface 10 to be cleaned.

[0062] In some examples, referring to Figures 3A and 3B, the size of the sealing portion 320 in the first direction Y gradually decreases from the fixed end 321 to the free end 322. As a result, the thickness of the sealing portion 320 gradually decreases from the fixed end 321 to the free end 322, and the structure of the sealing portion 320 is smoother and more aesthetically pleasing. In addition, during the process of the cleaning component changing from the initial state to the adsorption state, the pressure change in the adsorption chamber 410 is usually gradually reduced to a negative pressure. In addition, when adsorbed to different surfaces 10 to be cleaned, the pressure in the adsorption chamber 410 of the cleaning component under different working conditions may also be different accordingly. By setting the sealing portion 320 to a structure with a gradually decreasing thickness, it can adapt to different working conditions, thereby adaptively deforming according to the pressure difference between the adsorption chamber 410 and the external space.

[0063] In some examples, the first elastic sealing structure can be disposed around the adsorption chamber, thereby circumferentially sealing the cleaning assembly. For example, the second protruding member can be disposed around the adsorption chamber, and the first elastic sealing structure can be fixed to the second protruding member. For example, the first protruding member can be disposed around the adsorption chamber, and the first elastic sealing structure can be fixed to the first protruding member.

[0064] Referring to Figure 4, in some examples, a plurality of sealing portions 320 can be provided, and the plurality of sealing portions 320 can be provided at intervals 101 along the first direction Y. For example, by providing a plurality of sealing portions 320, the service life of the first elastic sealing structure 300 can be extended, and the risk of sealing failure of the first elastic sealing structure 300 due to fatigue failure of the sealing portion 320 closer to the opening 430 can be reduced. In addition, providing a plurality of sealing portions 320 along the flow path of the airflow can also improve the sealing effect of the first elastic sealing structure 300 and reduce the risk of poor sealing. The airflow flows through the opening 430 formed between the end of the first protruding part 110 and the second module 200. The plurality of sealing portions 320 arranged in the first direction Y can block the interval 101 from multiple positions, preventing the airflow from flowing into the adsorption chamber 410.

[0065] Figure 6 is a schematic diagram of a cleaning assembly provided by at least one embodiment of the present disclosure. The cleaning assembly shown in Figure 6 differs from the cleaning assembly shown in Figure 2 in that the first elastic sealing structure 300 in Figure 6 is different from the first elastic sealing structure 300 in Figure 2.

[0066] 6 , in some examples, a dimension of at least a portion of the first elastic sealing structure 300 in the second direction X is greater than or equal to a dimension of the space 101 in the second direction X, thereby sealing the space 101 in the second direction X via the first elastic sealing structure 300. Referring to FIG6 , the sealing portion of the first elastic sealing structure 300 can extend along the second direction X, such that an end of the sealing portion (e.g., a free end) distal from the connecting portion closely contacts one of the first protruding member 110 and the second protruding member 210, while simultaneously closely contacting the other of the first protruding member 110 and the second protruding member 210 via the connecting portion 310.

[0067] Referring to Figures 4 to 6, in some examples, at least two first elastic sealing structures 300 are provided. One of the first protruding part 110 and the second protruding part 210 is provided as at least one, and the other is provided as at least two; the first protruding part 110 and the second protruding part 210 are alternately arranged along the second direction X to form at least two air guide cavities 420. Taking Figure 4 as an example, an air guide cavity 420 is formed between adjacent first protruding parts 110 and second protruding parts 210. At least two first elastic sealing structures 300 are respectively provided in a corresponding air guide cavity 420, and the two adjacent first elastic sealing structures 300 are connected to form an integral structure. Taking Figure 4 as an example, the two connecting portions 310 in the two first elastic sealing structures 300 are connected to each other so that they can be sleeved on the second protruding part 210, facilitating the fixation of the first elastic sealing structure 300. 5 , the two connecting portions 310 of the two first elastic sealing structures 300 are connected to each other, so that they can be embedded between two adjacent first protruding parts 110, thereby facilitating the fixation of the first elastic sealing structure 300. Of course, the first elastic sealing structure can also be sleeved on the first protruding part, or the first elastic sealing structure can also be embedded between two adjacent second protruding parts, and this disclosure does not limit this.

[0068] In some examples, the cleaning assembly further includes a second elastic sealing structure. The first elastic sealing structure is connected to the first protruding member, and the second elastic sealing structure is connected to the second protruding member. Of course, the first elastic sealing structure may also be configured to be connected to the first protruding member, and the second elastic sealing structure may be configured to be connected to the first protruding member, and this disclosure is not limited thereto. At least a portion of the second elastic sealing structure is configured to be in close contact with the first elastic sealing structure to seal the gap. Thus, the gap can be sealed by sealing between the first and second elastic sealing structures. For example, the sealing portion of the first elastic sealing structure and the sealing portion of the second elastic sealing structure can overlap each other, thereby sealing the gap through close contact between the sealing portions. For example, the sealing portion of the first elastic sealing structure can abut against the connecting portion of the second elastic sealing structure, thereby sealing the gap. For example, the sealing portion of the second elastic sealing structure can abut against the connecting portion of the first elastic sealing structure, thereby sealing the gap. As long as the gap can be sealed through close contact between the first and second elastic sealing structures, this disclosure is not limited thereto.

[0069] With reference to Figures 1 to 6, for example, the shape of the first elastic sealing structure 300 and the shape of the second elastic sealing structure can be the same or different. For example, the shape of the first elastic sealing structure 300 and the shape of the second elastic sealing structure can both be the same as the shape of the first elastic sealing structure 300 shown in Figure 1, or can both be the same as the shape of the first elastic sealing structure 300 shown in Figures 4, 5, or 6. For example, the shape of the first elastic sealing structure 300 and the shape of the second elastic sealing structure can be the same as the shape of the first elastic sealing structure 300 shown in Figures 1, 4, 5, and 6, so that sealing is achieved by the first elastic sealing structure 300 and the second elastic sealing structure having different shapes. This disclosure is not limited to this.

[0070] Referring to Figures 1 to 6, in some examples, the first module 100 and the second module 200 are configured to be able to move relative to each other along a first direction Y, and at least a portion of the first elastic sealing structure 300 is configured to deform in response to the relative movement to seal the gap 101. During the relative movement of the first module 100 and the second module 200, the first elastic sealing structure 300 disposed between the first module 100 and the second module 200 may deform due to friction. For example, when the cleaning assembly is placed on the surface to be cleaned 10, the first module 100 is subjected to pressure and moves toward the second module 200. In this case, the first elastic sealing structure 300 may deform in response to the movement of the first module 100, sealing the gap 101 between the first module 100 and the second module 200, thereby improving the adsorption efficiency of the adsorption chamber 410.

[0071] Referring to Figures 2 to 6, for example, an adsorption chamber 410 is formed between the first module 100, the second module 200, and the surface to be cleaned 10. When the cleaning component is placed on the surface to be cleaned 10, the first module 100 moves toward the second module 200, causing the space of the adsorption chamber 410 to shrink and squeezing the air in the adsorption chamber 410 toward the outside of the cleaning component. At this time, a portion of the air can apply pressure to the free end 322 of the first elastic sealing structure 300, increasing the gap between the free end 322 and the first module 100 or the second module 200, thereby squeezing out the air in the adsorption chamber 410, so that the cleaning component is pre-pressed on the surface to be cleaned 10. Then, the remaining air in the adsorption chamber 410 can be further sucked out by the adsorption module to increase the pressure difference between the adsorption chamber 410 and the external space, so that the cleaning component is more firmly adsorbed on the surface to be cleaned 10.

[0072] 3A and 3B , as the first module 100 moves toward the second module 200, air within the adsorption chamber 410 can flow from the gap between the connecting portion 310 and the first protruding member 110 toward the side of the first elastic sealing structure 300 where the sealing portion 320 is located. Since the airflow s is now flowing from the adsorption chamber 410 toward the outside, it can exert a force on the free end 322, causing it to move closer to the connecting portion 310. This increases the gap between the free end 322 and the first protruding member 110, facilitating the discharge of the airflow s.

[0073] In addition, by setting the first module 100 and the second module 200 to be movable relative to each other, they can adapt to different surfaces 10 to be cleaned. For example, in some working conditions, the surface 10 to be cleaned may have protrusions, depressions, or other irregular shapes. When the cleaning module cleans the uneven surface 10 to be cleaned, the position and angle can be adjusted by the relative movement of the first module 100 and the second module 200, thereby increasing the contact area between the cleaning component and the surface 10 to be cleaned and improving the cleaning efficiency. For example, taking the surface 10 to be cleaned as the glass of a window as an example, different types of windows (such as sliding windows, push-pull windows, fixed windows, etc.) also have differences in shape and structure. By setting the first module 100 and the second module 200 to be movable relative to each other, the cleaning component can better adapt to different types of windows, ensuring a comprehensive and uniform cleaning effect.

[0074] Referring to Figures 1 to 6, in some examples, the second module 200 includes a bracket 220 and a wiper 230. The second protruding member 210 is disposed on a side of the bracket 220 facing the first module 100. For example, the second protruding member 210 can be connected to the bracket 220 to form an integral structure. The wiper 230 is connected to a side of the bracket 220 facing away from the second protruding member 210. The bracket 220 is configured to move relative to the first module 100 in a first direction Y, such that the wiper 230 moves with the movement of the bracket 220. The provision of a movable bracket 220 allows the wiper 230 to move flexibly, thereby ensuring that the wiper 230 can freely move according to the shape of the surface 10 to be cleaned when wiping an uneven surface 10, thereby improving cleaning efficiency and preventing scratches on the surface 10 to be cleaned.
