[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0027] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second", and the like used in the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different components. The terms such as "include" or "comprise" mean that the elements or items appearing before the term cover the elements or items listed after the term and their equivalents, without excluding other elements or items.

[0028] The features such as "vertical", "parallel", and "same" used in the present disclosure include the strict meanings of "vertical", "parallel", "same", etc., as well as the cases with certain errors such as "substantially vertical", "substantially parallel", "substantially same", etc. Considering the measurement and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system), it means within the acceptable deviation range for a specific value determined by those of ordinary skill in the art. The "center" in the embodiments of the present disclosure may include the position strictly located at the geometric center and the position of the approximate center within a small area around the geometric center. For example, "substantially" can mean within one or more standard deviations, or within 10% or 5% of the value.

[0029] Cleaning robots such as window cleaners, which combine sensing technology, a navigation system, and a cleaning mechanism, can perform cleaning tasks within the time and area set by the user, greatly reducing people's housework burden. In the research, the inventors of the present disclosure found that window cleaners have many components, which not only increases the assembly difficulty and the complexity of maintenance, but also causes the weight of the whole machine to increase and affects the adsorption force.

[0030] At least one embodiment of the present disclosure provides a cleaning disk structure configured to form an adsorption cavity with a surface to be cleaned; the cleaning disk structure includes: an annular disk, including a disk body structure, a positioning structure, and a first connection structure, the positioning structure and the first connection structure are respectively connected to the disk body structure; a connection disk, including a main body part, a matching structure, and a second connection structure, the matching structure and the second connection structure are respectively connected to the main body part; wherein, the positioning structure is configured to guide the matching structure to move to a positioning position so that the annular disk and the connection disk are positioned relative to each other in the circumferential direction of the annular disk; the first connection structure and the second connection structure are configured to engage with each other in the axial direction of the annular disk so that the annular disk and the connection disk are fixed to each other; the inner side wall of the annular disk forms at least part of the circumferential side wall of the adsorption cavity; the annular disk is further configured to generate a frictional force with the surface to be cleaned so that the cleaning disk structure moves relative to the surface to be cleaned.

[0031] At least one embodiment of the present disclosure provides a cleaning device including the above cleaning disk structure.

[0032] For the cleaning disk structure and the cleaning device provided by at least one embodiment of the present disclosure, when assembling the connection disk and the annular disk, the positioning structure guides the matching structure to achieve circumferential positioning, and the first connection structure and the second connection structure engage with each other to achieve fixation in the axial direction. The operator can correctly assemble the connection disk and the annular disk without directly seeing the assembly point, that is, the operator can achieve blind assembly, reducing the assembly difficulty. Moreover, at least part of the circumferential side wall of the adsorption cavity is formed by the inner side wall of the annular disk, and the annular disk is used to achieve walking, eliminating the need to additionally provide a walking disk and reducing the number of parts of the cleaning disk structure.

[0033] The cleaning disk structure and the cleaning device will be described below with reference to the accompanying drawings and through some embodiments.

[0034] Figure 1 It is a schematic diagram of the cleaning disk structure provided by an example in at least one embodiment of the present disclosure. Figure 2 It is a cross-sectional view of the cleaning disk structure provided by an example in at least one embodiment of the present disclosure.

[0035] Referring to Figure 1 and Figure 2 , at least one embodiment of the present disclosure provides a cleaning disk structure, and the cleaning disk structure is configured to form an adsorption cavity Z with a surface to be cleaned S0. For example, Figure 2Schematically shows that an adsorption cavity Z is formed by the direct contact between the cleaning disk structure and the surface S0 to be cleaned, but the present disclosure is not limited thereto. A wiping member may be provided outside the cleaning disk structure, and the surface to be cleaned is cleaned by the direct contact between the wiping member and the surface to be cleaned. For example, when the cleaning disk structure is applied to a cleaning device, a negative pressure can be provided to the adsorption cavity by an adsorption module (such as a blower) in the cleaning device, so that the whole cleaning device can be adsorbed on the surface to be cleaned without falling off.

[0036] Reference Figure 1 , the cleaning disk structure includes an annular disk 100 and a connecting disk 200. The annular disk 100 includes a disk body structure 110, a positioning structure 120, and a first connection structure 130, and the positioning structure 120 and the first connection structure 130 are respectively connected to the disk body structure 110. For example, the disk body structure 110, the positioning structure 120, and the first connection structure 130 are integrally formed structures. The connecting disk 200 includes a main body portion 210, a matching structure 220, and a second connection structure 230, and the matching structure 220 and the second connection structure 230 are respectively connected to the main body portion 210. For example, the main body portion 210, the matching structure 220, and the second connection structure 230 are integrally formed structures.

[0037] Reference Figure 1 and Figure 2 , the positioning structure 120 is configured to guide the matching structure 220 to move to a positioning position so that the annular disk 100 and the connecting disk 200 are positioned relative to each other in the circumferential direction of the annular disk 100. For example, during the assembly process, the operator can cause relative rotation between the annular disk 100 and the connecting disk 200. When rotated to the positioning position, the positioning structure 120 cooperates with the matching structure 220, thereby realizing the circumferential positioning of the annular disk 100 and the connecting disk 200. The first connection structure 130 and the second connection structure 230 are configured to engage with each other in the axial direction of the annular disk 100 so that the annular disk 100 and the connecting disk 200 are fixed to each other. For example, the axis of the annular disk 100 coincides with the rotation axis V of the cleaning disk structure, so that the axial direction of the annular disk 100 is parallel to the rotation axis V. For example, after realizing the circumferential positioning between the annular disk 100 and the connecting disk 200, a pressure in the axial direction can be applied to at least one of the annular disk 100 and the connecting disk 200, so that the first connection structure 130 and the second connection structure 230 are engaged, thereby realizing the reliable fixation of the annular disk 100 and the connecting disk 200.

[0038] Reference Figure 1 and Figure 2, when assembling the connection disk 200 and the annular disk 100, the positioning structure 120 guides the mating structure 220 to achieve circumferential positioning, and the first connection structure 130 and the second connection structure 230 are engaged with each other to achieve fixation in the axial direction. The operator can correctly assemble the connection disk 200 and the annular disk 100 without directly seeing the assembly point, that is, the operator can achieve blind assembly, reducing the assembly difficulty.

[0039] Reference Figure 1 and Figure 2 , the inner side wall W1 of the annular disk 100 forms at least part of the circumferential side wall W2 of the adsorption cavity Z, and the annular disk 100 is also configured to generate a frictional force with the surface S0 to be cleaned, so that the cleaning disk structure moves relative to the surface S0 to be cleaned. While the inner side wall of the annular disk forms at least part of the circumferential side wall of the adsorption cavity, the annular disk realizes walking, eliminating the need for an additional walking disk and reducing the number of parts of the cleaning disk structure.

[0040] For example, the annular disk can be an integrally formed structure, and the inner side wall of the integrally formed annular disk can form the entire circumferential side wall of the adsorption cavity. For example, the cleaning disk structure can also include other structures, and the annular disk can jointly form the circumferential side wall of the adsorption cavity with other structures. For example, the adsorption cavity can be jointly formed by the annular disk, the connection disk, and the surface to be cleaned, but the present disclosure is not limited thereto. For example, when the cleaning disk structure is applied to a cleaning device, the adsorption cavity can also be jointly formed by other structures in the cleaning device.

[0041] Reference Figure 1 and Figure 2 , for example, part of the positioning structure 120 can be a groove structure, and part of the mating structure 220 can be a protrusion structure, so that the protrusion structure and the groove structure realize the mating positioning of the positioning structure 120 and the mating structure 220. Thus, during the assembly process, when the operator makes the connection disk 200 and the annular disk 100 rotate relative to each other, when the protrusion structure falls into the groove structure, it is determined that the mating structure 220 is in the positioning position, realizing blind assembly. However, the present disclosure is not limited thereto, and part of the positioning structure can also be a protrusion structure, and part of the mating structure can be a groove structure.

[0042] Figure 3 is an exploded view of the cleaning disk structure provided by an example in at least one embodiment of the present disclosure. Figure 4 is a schematic diagram of the assembly of the annular disk and the connection disk provided by an example in at least one embodiment of the present disclosure.

[0043] Reference Figure 1 , Figure 3 and Figure 4, in some examples, the positioning structure 120 includes a first positioning portion 121 and a second positioning portion 122, and the mating structure 220 includes a first mating portion 221 and a second mating portion 222 located on both sides of the main body portion 210 in the axial direction. However, the present disclosure is not limited thereto. For example, the positioning structure 120 may also include only the first positioning portion 121 or only the second positioning portion 122. Correspondingly, the mating structure 220 may also include only the first mating portion 221 or only the second mating portion 222, so that positioning and clamping are achieved by one layer of structure.

[0044] Reference Figure 1 、 Figure 3 and Figure 4 , for example, one of the first positioning portion 121 and the first mating portion 221 is a convex structure, and the other is a groove structure. One of the second positioning portion 122 and the second mating portion 222 is a convex structure, and the other is a groove structure. For example, the first positioning portion 121 is a groove structure and the first mating portion 221 is a convex structure. For example, the second positioning portion 122 is a groove structure and the second mating portion 222 is a convex structure.

[0045] However, the present disclosure is not limited thereto. For example, the first positioning portion may also be a convex structure, the first mating portion may be a groove structure, the second positioning portion may be a convex structure, and the second mating portion may be a groove structure.

[0046] Reference Figure 1 、 Figure 3 and Figure 4 , in the positioning position of the mating structure 220, the first positioning portion 121 cooperates with the first mating portion 221, and the second positioning portion 122 cooperates with the second mating portion 222. For example, during the assembly process, the first mating portion 221 is guided by the first positioning portion 121 to move to the positioning position, and at the same time, the second mating portion 222 is guided by the second positioning portion 122 to move to the positioning position. For example, the first mating portion 221 and the second mating portion 222 have a height difference in the axial direction, and the first positioning portion 121 and the second positioning portion 122 also correspondingly have a height difference in the axial direction. Thus, the annular disk 100 and the connecting disk 200 can be guided and positioned by two layers of structures in the axial direction. The two-layer structure guiding and positioning can constrain the relative position relationship between the annular disk 100 and the connecting disk 200 from more positions, reduce the possible range of position deviation, and is beneficial to improving the accuracy and reliability of guiding and positioning.

[0047] Figure 5 Schematic diagrams of the front projection of the connecting disk of the cleaning disk structure, the front projection of the first mating portion, and the front projection of the second mating portion provided by an example in at least one embodiment of the present disclosure.

[0048] Reference Figures 3 to 5 , in some examples, on a reference plane S1 perpendicular to the axis direction, a ray R starting from the center of the orthographic projection P0 of the connecting disk 200 passes through the orthographic projection P1 of the first mating part 221 and the orthographic projection P2 of the second mating part 222. For example, in order to achieve guiding mating with the mating structure, on the reference plane, a ray starting from the center of the orthographic projection of the connecting disk passes through the orthographic projection of the first positioning part and the orthographic projection of the second positioning part.

[0049] Reference Figures 3 to 5 , for example, the line connecting the center of the first mating part 221 and the center of the connecting disk 200 can be on the same straight line as the line connecting the center of the second mating part 222 and the center of the connecting disk 200. For example, the line connecting the center of the first mating part and the center of the connecting disk and the line connecting the center of the second mating part and the center of the connecting disk can have a small included angle.

[0050] Reference Figures 3 to 5 , the first mating part 221 and the second mating part 222 having a height difference in the axis direction are closer in the circumferential direction of the connecting disk 200. Correspondingly, the first positioning part 121 and the second positioning part 122 having a height difference in the axis direction are also closer in the circumferential direction of the connecting disk 200. Thus, it is beneficial to the processing of the mating structure 220 and the positioning structure 120 and reduces the precision error.

[0051] However, the present disclosure is not limited thereto. For example, on the reference plane, a ray starting from the center of the orthographic projection of the connecting disk and passing through the orthographic projection of the first mating part may not pass through the orthographic projection of the second mating part, so that the first mating part and the second mating part can be offset from each other in the circumferential direction. Correspondingly, the first positioning structure and the second positioning structure can also be offset from each other in the circumferential direction, which will not be elaborated herein.

[0052] Reference Figure 3 , in some examples, an inwardly protruding flange 140 is provided on the inner side wall of the disk body structure 110, and the second positioning part 122 is provided on the flange 140. For example, the flange 140 can be located at the middle position of the inner side wall of the disk body structure 110 in the axis direction, so that the second positioning part 122 and the first positioning part 121 have a height difference in the axis direction. For example, a notch recessed in the direction from the center of the annular disk 100 to the edge can be formed on the flange 140 to form the second positioning part 122 of the groove structure.

[0053] Reference Figure 3 and Figure 4, for example, the second positioning portions 122 may be provided in a plurality, and the plurality of second positioning portions 122 are provided at intervals in the circumferential direction of the disk body structure 110. Correspondingly, the second mating portions 222 may also be provided in a plurality to mate with the plurality of second positioning portions 122 in a one-to-one correspondence.

[0054] Reference Figure 3 and Figure 4 , in some examples, the second mating portion 222 extends in a direction away from the first mating portion 221 along the axial direction. When the mating structure 220 is in the positioning position, at least a part of the second mating portion 222 extends into the second positioning portion 122, so that the second mating portion 222 and the second positioning portion 122 are positioned relative to each other in the circumferential direction of the disk body structure 110. For example, when the second positioning portion 122 is a groove structure, the second mating portion 222 may partially extend into the second positioning portion 122 or may entirely extend into the second positioning portion 122 to achieve the mating and positioning between the second positioning portion 122 and the second mating portion 222. Thus, the plurality of second mating portions 222 and the plurality of second positioning portions 122 can cooperate with each other, enabling the annular disk 100 and the connecting disk 200 to be positioned at a plurality of positions in the circumferential direction, improving the reliability of positioning.

[0055] Reference Figure 3 and Figure 4 , in some examples, the disk body structure 110 includes two surfaces opposite to each other in the axial direction, and the first connecting structures 130 are provided in a plurality, and the plurality of first connecting structures 130 are provided at intervals in the circumferential direction of the disk body structure 110. The first connecting structure 130 includes a protruding portion 131 protruding from one surface (for example, the first surface 101) of the two surfaces close to the connecting disk 200, and a first positioning portion 121 is formed between the protruding portions 131 of two adjacent first connecting structures 130. Thus, the first positioning portion 121 in the form of a groove structure can be formed by two adjacent protruding portions 131.

[0056] Figure 6 For Figure 2 the partial enlarged schematic view at position A shown.

[0057] Reference Figure 2 、 Figure 3 and Figure 6, for example, each first connection structure 130 may include two protruding portions 131, and a clamping groove is formed between the two protruding portions 131. The second connection structure 230 may be an elastic hook structure. When assembling the annular disk 100 and the connection disk 200, the hook structure can be elastically deformed under force and is clamped in the clamping groove by the hook structure, so as to realize the mutual fixation of the connection disk 200 and the annular disk 100. However, the present disclosure is not limited thereto, and the first connection structure and the second connection structure may also be clamped to each other in other ways to achieve fixation.

[0058] Reference Figure 3 and Figure 5 , for example, the first mating portion 221 may protrude outward from the main body portion 210 along a direction pointing from the center of the connection disk 200 to the edge, for example, the first mating portion 221 is located on the outer circumference of the main body portion 210. When the mating structure 220 is in the positioning position, at least a part of the first mating portion 221 extends into the first positioning portion 121, so that the first mating portion 221 and the first positioning portion 121 are positioned relative to each other in the circumferential direction of the disk structure 110. For example, the first mating portion may completely extend into the first positioning portion or partially extend into the first positioning portion, and the present disclosure does not limit this.

[0059] Reference Figure 3 , in some examples, the disk structure 110 includes two surfaces opposite to each other in the axial direction, and the surface of the two surfaces close to the connection disk 200 is the first surface 101. The dimension of the first mating portion 221 in the axial direction is the first dimension D1, and the dimension between the edge of the first connection structure 130 away from the first surface 101 and the first surface 101 in the axial direction is the second dimension D2, and the first dimension D1 is equal to the second dimension D2.

[0060] Reference Figure 3 , for example, a protruding portion 131 of the first connection structure 130 is formed between the edge of the first connection structure 130 away from the first surface 101 and the first surface 101, and the dimension of the protruding portion 131 in the axial direction is the second dimension D2. At the same time, two adjacent protruding portions 131 form the first positioning portion 121, so that the second dimension D2 is equal to the dimension of the first positioning portion 121 in the axial direction. Thus, the first dimension D1 is equal to the second dimension D2, so that the first connection structure 130 can completely extend into the first positioning portion 121, which is beneficial to making the surface of the cleaning disk structure tend to be flat after the annular disk 100 and the connection disk 200 are connected.

[0061] Reference Figure 1 、 Figure 3 and Figure 4, in some examples, the second connection structure 230 is provided in multiple numbers, and the first mating part 221 is provided in multiple numbers. The multiple second connection structures 230 and the multiple first mating parts 221 are alternately arranged at intervals in the circumferential direction of the main body part 210. Thus, the multiple first mating parts 221 can cooperate with the multiple first positioning parts 121, and at the same time, the multiple first connection structures 130 can engage with the multiple second connection structures 230, enabling the circumferential force on the annular disk 100 and the connection disk 200 to be more uniform and the connection to be more reliable.

[0062] Reference Figure 1 , in some examples, the annular disk 100 is an integrally formed structure, and at least part of the annular disk 100 is configured to undergo elastic deformation so that the cleaning disk structure can adapt to different surfaces by elastic deformation, such as a curved surface or an inclined surface. For example, the annular disk can be formed by two disk structures and an adhesive layer integrally formed between the two disk structures, thereby realizing the elastic deformation of the annular disk through the adhesive layer. By setting the annular disk as an integrally formed structure, there is no need to additionally add components such as seals and elastic parts, reducing the number of components of the cleaning disk structure and simplifying the assembly process.

[0063] Figure 7 It is a schematic diagram of the annular disk provided by an example in at least one embodiment of the present disclosure.

[0064] Reference Figure 1 、 Figure 2 And Figure 7 , in some examples, the cleaning disk structure is configured to rotate around the rotation axis V, and the rotation axis V intersects with the surface to be cleaned S0 and is not perpendicular to each other. Thus, the pressure exerted by the cleaning disk structure on the surface to be cleaned S0 is different, enabling the cleaning disk structure to generate different frictional forces at different circumferential positions, which is beneficial to the movement of the cleaning disk structure.

[0065] Reference Figure 1 And Figure 2 , in some examples, when an adsorption cavity Z is formed between the cleaning disk structure and the surface to be cleaned S0, the elastic deformation amounts of the annular disk 100 at at least two circumferential positions are different. For example, since the rotation axis V intersects with the surface to be cleaned S0 and is not perpendicular to each other, by having at least two different elastic deformation amounts of the annular disk 100 in the circumferential direction, the adsorption cavity Z can be kept sealed without air leakage.

[0066] Reference Figure 1 、 Figure 3 And Figure 7, in some examples, the maximum dimension T1 of the annular disk 100 in the axial direction is greater than the maximum dimension T2 of the connecting disk 200 in the axial direction. Thus, the thickness of the annular disk 100 is greater than that of the connecting disk 200, so that when the cleaning disk structure is adsorbed to the surface S0 to be cleaned, sufficient space is reserved between the connecting disk 200 and the surface S0 to be cleaned, improving the adsorption stability of the adsorption cavity Z. In addition, a deformation space can also be reserved between the connecting disk 200 and the surface S0 to be cleaned for the annular disk 100, which is beneficial to adapt to different surfaces.

[0067] Reference Figures 1 to 3 、 Figure 7 , in some examples, the disk body structure 110 includes a first disk body 111 and a second disk body 112 arranged oppositely, and the inner side walls of the first disk body 111 and the second disk body 112 form at least part of the circumferential side walls of the adsorption cavity Z. The cleaning disk structure further includes a sealing structure 150 and an elastic structure 160 arranged between the first disk body 111 and the second disk body 112. The sealing structure 150 is configured to seal the gap D between the first disk body 111 and the second disk body 112 at least when the adsorption cavity Z is formed, and the elastic structure 160 is configured to provide an elastic acting force between the first disk body 111 and the second disk body 112 to change the dimension of the gap D in the direction from the second disk body 112 to the first disk body 111.

[0068] Reference Figures 1 to 3 、 Figure 7 , the elastic structure 160 arranged between the first disk body 111 and the second disk body 112 can change the dimension of the gap D through the elastic acting force of the elastic structure 160, so that the cleaning disk structure can be kept in close contact with the surface S0 to be cleaned in different use scenarios. At the same time, the sealing structure 150 can undergo adaptive deformation according to gaps of different sizes to seal the gap D. Thus, through the cooperative action of the elastic structure 160 and the sealing structure 150, the intake air volume of the cleaning disk structure can be adjusted, improving the adsorption stability of the adsorption cavity Z, thereby reducing the risk of the cleaning device using the cleaning disk structure from slipping.

[0069] For example, the first disk body 111, the positioning structure 120 and the first connecting structure 130 are integrally formed structures. Thus, there is no need to consider the assembly between the first disk body 111, the positioning structure 120 and the first connecting structure 130, simplifying the assembly process.
