CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a Continuation of International Application No. PCT / CN2024 / 112887, filed on Aug. 16, 2024, which claims priority to Chinese Patent Application No. 202322310901.8, filed on Aug. 25, 2023, the entire contents of each of which are hereby incorporated by reference.TECHNICAL FIELD

[0002] The present disclosure generally relates to a field of cleaning technology, and in particular, to a cleaning belt assembly and a cleaning apparatus.BACKGROUND

[0003] With the development of technology, more and more cleaning apparatuses have appeared on the market. Some cleaning apparatuses with a mopping function achieve cleaning by dragging and wiping a surface to be cleaned with a cleaning belt. Because the cleaning belt is in long-term contact with a dirty surface, the cleaning belt needs to be replaced after being used for a period of time to avoid secondary pollution during a cleaning process. An existing cleaning belt is usually fixed on a cleaning apparatus, making installation and removal inconvenient and hindering quick replacement by users.

[0004] Therefore, it is desirable to provide a cleaning belt assembly and a cleaning apparatus, which can facilitate the user to quickly replace the cleaning belt.SUMMARY

[0005] One or more embodiments of the present disclosure provide a cleaning belt assembly. The cleaning belt assembly includes: an annular belt, a first roller, a second roller, a first support member, and a second support member. The first roller and the second roller are spaced apart. The annular belt is rotatably wound around the first roller and the second roller. The first roller is rotatably connected to the first support member. The second roller is rotatably connected to the second support member. The first support member and the second support member are rotatably connected via a rotating shaft. The first support member and the second support member are capable of adjusting an included angle between the first support member and the second support member through relative rotation between the first support member and the second support member, thereby adjusting a spacing between the first roller and the second roller.

[0006] One or more embodiments of the present disclosure provide a cleaning apparatus. The cleaning apparatus includes the cleaning belt assembly.

[0007] The cleaning belt assembly according to one or more embodiments of the present disclosure includes the annular belt, the first roller, the second roller, the first support member, and the second support member. During use, a user causes relative rotation between the first support member and the second support member to adjust the included angle between the first support member and the second support member, thereby adjusting the spacing between the first roller and the second roller. When the user increases the spacing between the first roller and the second roller, the annular belt wound around the first roller and the second roller is tensioned. In this state, the annular belt may be used to wipe a surface to be cleaned. When the user decreases the spacing between the first roller and the second roller, causing the annular belt wound around the first roller and the second roller to be in a loose state, the user can easily detach the annular belt and replace it with a new annular belt. After the annular belt is replaced, the user re-adjusts the spacing between the first roller and the second roller to tension the annular belt. Therefore, the cleaning belt assembly allows for simple and quick installation and removal of the annular belt, enabling the user to replace it rapidly while saving time and effort.BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Hereinafter, preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are assigned to the same components, and repeated descriptions are omitted. In addition, the drawings are schematic diagrams, and a ratio of dimensions between components or a shape of a component may be different from an actual ratio or shape.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present disclosure are only used to explain a relative positional relationship and movement between components in a specific posture. When the specific posture changes, the directional indication changes accordingly.

[0030] It should also be noted that when an element is referred to as being “fixed to” or “disposed on” another element, the element may be directly on the other element or there may be an intervening element. When an element is referred to as being “connected” to another element, the element may be directly connected to the other element or there may be an intervening element.

[0031] In addition, descriptions involving “first”, “second”, etc., in the present disclosure are for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating a quantity of the indicated technical features. Thus, features defined with “first” and “second” may explicitly or implicitly include at least one such feature. In addition, technical solutions of a plurality of embodiments may be combined with each other, but the combination must be based on what can be achieved by a person of ordinary skill in the art. When a combination of technical solutions is contradictory or cannot be achieved, the combination should be considered not to exist and is not within the scope of protection claimed in the present disclosure.

[0032] With the development of technology, more and more cleaning apparatuses have appeared on the market. Some cleaning apparatuses with a mopping function achieve cleaning by dragging a cleaning belt across a surface to be cleaned. Because the cleaning belt is in long-term contact with a dirty surface, the cleaning belt needs to be replaced after being used for a period of time to avoid secondary pollution during the cleaning process. Existing cleaning belts are usually fixed to the cleaning apparatus, making installation and removal inconvenient and hindering quick replacement by users.

[0033] FIG. 1 is a side view of a cleaning belt assembly according to some embodiments of the present disclosure. FIG. 2 is a schematic diagram of an overall structure of the cleaning belt assembly according to some embodiments of the present disclosure. FIG. 3 is a schematic diagram of a partial structure of the cleaning belt assembly according to some embodiments of the present disclosure. FIG. 4 is a state diagram illustrating a first support member and a second support member rotating relative to each other toward a second side according to some embodiments of the present disclosure.

[0034] As shown in FIG. 1 to FIG. 4, some embodiments of the present disclosure provide a cleaning belt assembly 10. The cleaning belt assembly 10 includes an annular belt 20, a first roller 30, a second roller 40, a first support member 50, and a second support member 60. The first roller 30 and the second roller 40 are spaced apart, and the annular belt 20 is rotatably wound around the first roller 30 and the second roller 40. The first roller 30 is rotatably connected to the first support member 50, and the second roller 40 is rotatably connected to the second support member 60. The first support member 50 and the second support member 60 are rotatably connected via a rotating shaft 70, and are capable of adjusting an included angle between the first support member 50 and the second support member 60 through relative rotation between the first support member 50 and the second support member 60, thereby adjusting a spacing between the first roller 30 and the second roller 40.

[0035] The annular belt 20 may be used to directly contact and drag a surface to be cleaned. A material of the annular belt 20 may include rubber, fabric, or the like. In some embodiments, the annular belt 20 is configured to be wound around the first roller 30 and the second roller 40 to form a closed loop. When the cleaning belt assembly 10 cleans the surface to be cleaned, the annular belt 20 rotates cyclically along surfaces of the first roller 30 and the second roller 40. In a working mode, the first roller 30 and the second roller 40 may keep the annular belt 20 tensioned, and the second roller 40 may press the annular belt 20 against the surface to be cleaned.

[0036] The first roller 30 and the second roller 40 being spaced apart refers to an axis of the first roller 30 and an axis of the second roller 40 being parallel and not coincident.

[0037] The first support member 50 is configured to carry and mount the first roller 30. The second support member 60 is configured to carry and mount the second roller 40. The first support member 50 and the second support member 60 are skeleton structures of the cleaning belt assembly 10.

[0038] Merely by way of example, two ends of the first support member 50 are provided with first connecting frames 11 (as shown in FIG. 6). The first connecting frames 11 are fixedly connected to the first support member 50 and are rotatably connected to the first roller 30, thereby supporting the first roller 30. For example, each of the first connecting frames 11 includes a rotating shaft portion 111 and a connecting portion 112. The rotating shaft portion 111 is rotatably connected to the first roller 30. The connecting portion 112 is fixedly connected to the first support member 50. The fixed connection method may be implemented through a plurality of methods, e.g., screws, interference fit, or the like. The rotatable connection may be implemented through means such as cooperation between a shaft and a bearing, or the like. A structure of the second support member 60 is similar to a structure of the first support member 50, and details are not repeated.

[0039] The first support member 50 and the second support member 60 are respectively configured with through holes to accommodate the rotating shaft 70 for passing through, thereby achieving a rotatable connection between the first support member 50 and the second support member 60 via the rotating shaft 70. A shape of each of the through holes matches the rotating shaft 70.

[0040] When the cleaning belt assembly 10 according to some embodiments of the present disclosure is in use, the user causes the first support member 50 and the second support member 60 to rotate relative to each other to adjust the included angle between the first support member 50 and the second support member 60, thereby adjusting the spacing between the first roller 30 and the second roller 40.

[0041] FIG. 5 is an exploded view of a partial structure of the cleaning belt assembly according to some embodiments of the present disclosure. FIG. 6 is another exploded view of a partial structure of the cleaning belt assembly according to some embodiments of the present disclosure. FIG. 7 is another exploded view of a partial structure of the cleaning belt assembly according to some embodiments of the present disclosure.

[0042] In some embodiments, with reference to FIG. 4 to FIG. 7, when adjusting the spacing, the user may fold the first support member 50 and the second support member 60 around the rotating shaft 70, so that an included angle exists between the first support member 50 and the second support member 60 to adjust the spacing between the first roller 30 and the second roller 40. When the user widens the spacing between the first roller 30 and the second roller 40, the annular belt 20 wound around the first roller 30 and the second roller 40 is in a tensioned state, and the annular belt 20 may be used to drag the surface to be cleaned at this time. When the user narrows the spacing between the first roller 30 and the second roller 40, the annular belt 20 wound around the first roller 30 and the second roller 40 is in a relaxed state, and the user may easily remove and then replace the annular belt 20 with a new one. After the annular belt 20 is replaced, the user readjusts the spacing between the first roller 30 and the second roller 40 to tension the annular belt 20. The disassembly and assembly of the annular belt 20 are simple and quick, thereby allowing the user to quickly replace the annular belt 20 and saving time and effort.

[0043] FIG. 8 is a schematic diagram of a partial structure of the first support member according to some embodiments of the present disclosure. FIG. 9 is a schematic diagram of a first plane and a second plane according to some embodiments of the present disclosure. FIG. 10 is another schematic diagram of the first plane and the second plane according to some embodiments of the present disclosure.

[0044] As shown in FIG. 1, FIG. 9, and FIG. 10, in some embodiments, the cleaning belt assembly 10 includes a first side 10a and a second side 10b opposite to each other. The first support member 50 and the second support member 60 form a first included angle A facing the first side 10a, and when the first support member 50 and the second support member 60 rotate relative to each other such that the first included angle A reaches a first angle, the spacing between the first roller 30 and the second roller 40 is at a first spacing, thereby tensioning the annular belt 20. The first support member 50 and the second support member 60 form a second included angle B facing the second side 10b, and when the first support member 50 and the second support member 60 rotate relative to each other such that the second included angle B reaches a second angle, the spacing between the first roller 30 and the second roller 40 is less than a second spacing, thereby releasing tension on the annular belt 20. The second angle is less than the first angle.

[0045] Merely by way of example, when the cleaning belt assembly 10 is performing a cleaning operation, the annular belt 20 is sleeved outside the first roller 30 and the second roller 40. The first side 10a is a side facing away from the surface to be cleaned (i.e., an upper side). The second side 10b is a side facing the surface to be cleaned (i.e., a lower side).

[0046] As shown in FIG. 1 and FIG. 9, when the annular belt 20 needs to be adjusted to the tensioned state, the user may rotate the first support member 50 and the second support member 60 toward the first side 10a, so that the first support member 50 and the second support member 60 are adjusted to a state where the first included angle A is at the first angle.

[0047] In some embodiments, the first angle may specifically be a fixed value.

[0048] The first angle may be greater than or equal to 100° and less than 180°. Merely by way of example, the first angle may include 170°, 160°, 155°, etc.

[0049] In some embodiments, the first angle A may be a selected fixed value within a first preset range. The first spacing may also be any fixed value within a second preset range. For example, the first angle A may be in a range of 160° to 175°. Therefore, when the first angle A is at any angle within 160° to 175°, the first spacing corresponds to any spacing within the second preset range. In some embodiments, the annular belt 20 includes an elastic base layer and a cleaning layer disposed on the elastic base layer. When the spacing between the first roller 30 and the second roller 40 is adjusted to the first spacing (i.e., any value within the second preset range), the annular belt 20 is in the tensioned state because the annular belt 20 is elastic. In the operating mode, the cleaning layer of the annular belt 20 contacts the surface to be cleaned. The first preset range is a range value preset by the user. Merely by way of example, the first preset range may be greater than or equal to 150° and less than 180°.

[0050] It can be understood that when the first spacing is less than a first spacing threshold, the annular belt 20 is in a slightly tensioned state. When the first spacing is greater than or equal to the first spacing threshold, the annular belt 20 is in a relatively tight tensioned state. The first spacing threshold is a value preset by the user. For example, the first spacing threshold is a spacing between the first roller and the second roller when the elastic base layer of the annular belt 20 is slightly stretched. The tensioned state refers to a state where the annular belt 20 has a tensioning force, and there is no gap or a very small gap between the annular belt 20 and the first roller 30 or the second roller 40.

[0051] In some embodiments, the first angle A is a selected fixed value within the first preset range, and the first spacing is also a selected fixed value within the second preset range. This means that in specific scenarios, for different cleaning belt assemblies 10, the first angle A may be the same or different, as long as it falls within the first preset range. For example, the first angle A corresponding to one cleaning belt assembly 10 is 175°, and the first angle A corresponding to another cleaning belt assembly 10 is 174°. The present disclosure does not specifically limit this.

[0052] In some embodiments, the first angle A may be greater than 175°. The present disclosure does not limit this.

[0053] As shown in FIG. 1 and FIG. 10, when tensioning of the annular belt 20 needs to be released, the user rotates the first support member 50 and / or the second support member 60 toward the second side 10b, so that the first support member 50 and the second support member 60 are adjusted to a state where the second included angle B is at the second angle.

[0054] In some embodiments, the second angle may be a value within a specific range or a fixed value. The second spacing may be a fixed value.

[0055] For example, the second angle may be a value within a range of 90° to 150°. When the second included angle B is at the second angle, the spacing between the first roller 30 and the second roller 40 is less than the second spacing.

[0056] The second spacing may also be referred to as a critical spacing value. The second spacing may be a critical value at which the annular belt 20 begins to transition to the relaxed state.

[0057] The relaxed state refers to a state where the annular belt 20 loses the tensioning force. In the relaxed state, the annular belt 20 no longer tightly encircles the first roller 30 or the second roller 40, and a gap is generated between the annular belt 20 and a surface of the first roller 30 or the second roller 40. For example, the gap exists between the elastic base layer and the surface of the first roller 30 or the second roller 40.

[0058] That is, when the spacing between the first roller 30 and the second roller 40 is less than the second spacing, the annular belt 20 is in the relaxed state. The smaller the second angle, the closer the spacing between the first roller 30 and the second roller 40, and the higher the degree of relaxation of the annular belt 20.

[0059] In some embodiments, the second angle may also correspond to other ranges. For example, the second angle may be a value within a range of 80° to 140°, or the second angle may be a value within a range of 80° to 155°, or the second angle may be a value less than 150°. The present disclosure does not limit this.

[0060] In some embodiments, the second angle B being a value within a specific range means that, in a specific scenario, for one cleaning belt assembly 10, when the second included angle B is at any value within the range corresponding to the second angle, the annular belt 20 is caused to be in the relaxed state, thereby facilitating disassembly of the annular belt 20. In some embodiments, the second angle being less than the first angle means that, for one cleaning belt assembly 10, a maximum value of the second angle is also less than the first angle. In addition, the included angle, the first included angle A, and the second included angle B described in the present disclosure refer to angles less than 180°.

[0061] In some embodiments, the cleaning belt assembly 10 further includes a limiting mechanism 80. The limiting mechanism 80 is configured to limit a limit position of the relative rotation between the first support member 50 and the second support member 60. For example, the limiting mechanism 80 may cause the first included angle A formed by the first support member 50 and the second support member 60 to be at the first angle. As another example, the limiting mechanism 80 may also limit a limit position when the first support member 50 and the second support member 60 rotate relative to each other toward the second side 10b.

[0062] The limiting mechanism 80 may block the first support member 50 and the second support member 60 from continuing to rotate. When the first support member 50 and the second support member 60 are limited by the limiting mechanism 80, the first included angle A formed between the first support member 50 and the second support member 60 is the first angle. The user does not need to confirm by other means whether the angle adjustment is complete. For example, the limiting mechanism 80 is a baffle disposed on the first support member 50 or the second support member 60 near a rotating shaft.

[0063] In some embodiments, as shown in FIG. 3 to FIG. 8, the limiting mechanism 80 includes one or more first limiting members 81. The one or more first limiting members 81 are configured to limit the limit position of the relative rotation between the first support member 50 and the second support member 60, such that the first included angle A formed by the first support member 50 and the second support member 60 is at the first angle.

[0064] The annular belt 20 is elastic. The annular belt 20 cooperates with the one or more first limiting members 81 to cause the first included angle A to be at the first angle.

[0065] In some embodiments, the elastic annular belt 20 abuts tightly against the first roller 30 and the second roller 40. Under an elastic restoring force of the annular belt 20, the first support member 50 and the second support member 60 cause the first included angle A to be at the first angle. The first limiting members 81 are configured to limit a rotational tendency of the first support member 50 and / or the second support member 60 toward the first side 10a. The annular belt 20 provides the elastic restoring force to prevent rotation of the first support member 50 and / or the second support member 60 toward the second side 10b. Consequently, the first support member 50 and the second support member 60 reach an equilibrium state without an external force, causing the first included angle A to be at the first angle. The elastic restoring force of the annular belt 20 tends to decrease the spacing between the first roller 30 and the second roller 40, i.e., tends to decrease the first included angle A. However, the first limiting members 81 restrict the first included angle A from further decreasing. Therefore, the equilibrium state can be maintained.

[0066] By setting the first included angle to less than 180°, the first support member 50 and the second support member 60 are given a tendency to rotate toward the first side 10a. Providing the first limiting members 81 may obstruct this rotational tendency. As the annular belt 20 is tightened around the first roller 30 and the second roller 40, the tension on the annular belt 20 further strengthens this rotational tendency, forcing the first support member 50 and the second support member 60 to abut against the first limiting members 81.

[0067] If the first included angle is set to 180°, the tension on the annular belt 20 may create simultaneous tendencies for the first roller 30 and the second roller 40 to rotate toward both the first side and the second side, resulting in an unstable state. Therefore, an additional locking mechanism is necessary, and locking mechanism needs to switch between specific states, e.g., a locked state and an unlocked state. Such complexity may increase the time cost for disassembly and impact quick-release efficiency. The combined effect of the first limiting members 81 and setting the first included angle to less than 180° allows the first roller 30 and the second roller 40 to maintain a stable state without requiring the additional locking mechanism. When replacing the annular belt 20, the user only needs to apply a slight force to rotate the first support member 50 and the second support member 60 toward the second side 10b. Once the first included angle exceeds 180°, the tension on the annular belt 20 may further promote the rotation of the first support member 50 and the second support member 60 toward the second side 10b, thereby enabling quick replacement.

[0068] In some embodiments, the one or more first limiting members 81 may be connected to the first support member 50 or the second support member 60. When the first support member 50 and the second support member 60 rotate relative to each other to the limit position, the first support member 50 or the second support member 60 abuts against the one or more first limiting members 81. At this time, the first included angle A is also the first angle. Only one first limiting member 81 may be provided. For example, the first limiting member 81 is disposed at a middle position of the first support member 50 along an axial direction of the first roller 30.

[0069] As shown in FIG. 3 to FIG. 8, in some embodiments, the one or more first limiting members 81 are disposed on a side of the first support member 50 (e.g., a side close to the second support member 60, or the like) and extend toward the first side 10a. When the second support member 60 abuts against at least one of the one or more first limiting members 81, the first included angle A formed by the first support member 50 and the second support member 60 is at the first angle.

[0070] When the first support member 50 and the second support member 60 rotate relative to each other toward the first side 10a, the first limiting members 81 may limit the limit position of the rotation.

[0071] When wiping the surface to be cleaned, the cleaning belt assembly 10 exerts a pressure on the surface to be cleaned. Because the first limiting members 81 extend toward the first side 10a, a reaction force from the surface to be cleaned on the cleaning belt assembly 10 causes the second support member 60 to abut more tightly against the first limiting member 81, keeping the structure of the cleaning belt assembly 10 stable.

[0072] As shown in FIG. 3 to FIG. 8, in some embodiments, the limiting mechanism 80 further includes one or more second limiting members 82. The one or more second limiting members 82 are configured to limit the limit position of the relative rotation between the first support member 50 and the second support member 60.

[0073] In some embodiments, the one or more second limiting members 82 are disposed on a side of the first support member 50 (e.g., a side near the first limiting member and close to the second side 10b, or the like) and extend toward the second side 10b.

[0074] When the first support member 50 and the second support member 60 rotate relative to each other toward the second side 10b, the one or more second limiting members 82 are configured to limit the limit position of the rotation. When the second support member 60 abuts against at least one of the one or more second limiting members 82, the second included angle B formed by the first support member 50 and the second support member 60 is the second angle.

[0075] As shown in FIG. 8, in some embodiments, one or more connecting arc sections 83 are disposed among the one or more first limiting members 81 and the one or more second limiting members 82. The one or more connecting arc sections 83 are respectively connected to the one or more first limiting members 81 and the one or more second limiting members 82. The one or more first limiting members 81, the one or more second limiting members 82, the one or more connecting arc sections 83, and the first support member 50 are integrally formed. Integral forming may be implemented by a plurality of methods, e.g., through machining, injection molding, or the like.

[0076] The integral forming can make limiting by the first limiting members 81 and the second limiting members 82 more reliable. The integral forming can also make the structure of the cleaning belt assembly 10 more concise, reduce redundant connection structures, and avoid accumulation of dust or oil stains at connection gaps.

[0077] For example, as shown in FIG. 8, the limiting mechanism 80 is staggered from the rotating shaft 70, i.e., a setting position of the limiting mechanism 80 does not overlap with the first support member 50 shown in FIG. 8. The first limiting members 81 and the second limiting members 82 form a V-shape less than 180° and greater than 90°.

[0078] In some embodiments, the first support member 50 includes one first rotating portion 51. The second support member 60 includes one second rotating portion 61. Merely by way of example, the one first rotating portion 51 and the one second rotating portion 61 are disposed between two first limiting members 81.

[0079] As shown in FIG. 7, in some embodiments, the first support member 50 includes a plurality of first rotating portions 51. The second support member 60 includes a plurality of second rotating portions 61. The rotating shaft 70 passes alternately through the plurality of first rotating portions 51 and the plurality of second rotating portions 61. The plurality of first rotating portions 51 and the plurality of second rotating portions 61 are configured to cooperate with the rotating shaft 70 to rotatably connect the first support member 50 and the second support member 60.

[0080] When the first support member 50 and the second support member 60 rotate relative to each other, the first limiting members 81, the connecting arc sections 83, and the second limiting members 82 move relative to an outer wall of the second rotating portion 61.

[0081] In some embodiments, as shown in FIG. 3, after the first support member 50 and the second support member 60 are assembled, the first limiting members 81 are located on a side of the second rotating portion 61 facing the first side 10a. When the first support member 50 and the second support member 60 rotate relative to each other, the first limiting members 81, the connecting arc sections 83, and the second limiting member 82 are all spaced equidistantly from the outer wall of the second rotating portion61, with only a slight gap therebetween (e.g., the gap is not greater than 0.1 mm).

[0082] By limiting the gap between each of the first limiting members 81, the connecting arc sections 83, and the second limiting members 82, and the outer wall of the second rotating portion 61, rotation of the first support member 50 and the second support member 60 becomes more stable, avoiding wobbling caused by an excessively large gap or an uneven gap.

[0083] To improve cleaning efficiency, the cleaning belt assembly 10 may also be made longer along the axial direction of the rotating shaft 70. This ensures a larger contact area between the annular belt 20 and the surface to be cleaned, resulting in higher efficiency in wiping the surface to be cleaned.

[0084] As shown in FIG. 7, in some embodiments, the limiting mechanism 80 includes the one or more first limiting members 81. The first support member 50 includes the plurality of first rotating portions 51. The second support member 60 includes the plurality of second rotating portions 61. The plurality of first rotating portions 51 and the plurality of second rotating portions 61 are distributed alternately along the axial direction of the rotating shaft 70. Each of the first limiting members 81 corresponds to one of the second rotating portions 61.

[0085] Alternate distribution refers to alternating arrangement of the plurality of first rotating portions 51 and the plurality of second rotating portions 61 along the axial direction (i.e., a length direction) of the rotating shaft 70. Merely by way of example, the plurality of second rotating portions 61 and the one or more first limiting members 81 are at a same axial position. Each of the plurality of first rotating portions 51 is located between two second rotating portions 61.

[0086] When the plurality of first rotating portions 51 and the plurality of second rotating portions 61 are distributed alternately along the axial direction of the rotating shaft 70, the cleaning belt assembly 10 may also be made longer along the axial direction of the rotating shaft 70. The arrangement where the first rotating portion 51 and the plurality of second rotating portions 61 are distributed alternately along the axial direction of the rotating shaft 70 can also make rotation of the first support member 50 and the second support member 60 more stable.

[0087] FIG. 11 is a schematic diagram of a partial structure of a cleaning belt assembly according to some other embodiments of the present disclosure. FIG. 12 is a state diagram illustrating a first support member and a second support member rotating relative to each other toward a second side of the cleaning belt assembly according to some other embodiments of the present disclosure.

[0088] As shown in FIG. 12, in some embodiments, the limiting mechanism 80 may also include: a first limiting surface 84 disposed on the first support member 50 and proximate to an end of the second support member 60, and a second limiting surface 85 disposed on the second support member 60 and proximate to an end of the first support member 50. The first limiting surface 84 and the second limiting surface 85 cooperate to limit the limit position of the relative rotation between the first support member 50 and the second support member 60, so that the first included angle A formed by the first support member 50 and the second support member 60 is at the first angle. With cooperation of the annular belt 20, the first included angle A is stabilized at the first angle.

[0089] By providing the first limiting surface 84 and the second limiting surface 85, when the first support member 50 and the second support member 60 rotate relative to each other to a preset position, limiting can be achieved through cooperation of ends of the first support member 50 and the second support member 60. The structure is simple and convenient to use.

[0090] FIG. 13 is an exploded view of the cleaning belt assembly according to some other embodiments of the present disclosure.

[0091] As shown in FIG. 13, in some embodiments, the first limiting surface 84 includes a first free surface 841 and a first abutting surface 842. The first free surface 841 rotates relative to the second limiting surface 85. The first abutting surface 842 is configured to abut against the second limiting surface 85 to limit the limit position of the relative rotation between the first support member 50 and the second support member 60. The first free surface 841 includes a curved surface and / or a slanted surface. The first abutting surface 842 includes a flat surface. The second limiting surface 85 includes a flat surface. The first abutting surface 842 protrudes toward the first side 10a relative to the first free surface 841. That is, a distance between at least a portion of the first abutting surface 842 and the rotating shaft 70 is greater than a distance between the first free surface 841 and the rotating shaft 70. When the first free surface 841 is a curved surface, the distance between the first free surface 841 and the rotating shaft 70 may be measured by a radial distance from the rotating shaft 70 to the first free surface 841.

[0092] When the annular belt 20 is replaced, the user adjusts the first support member 50 and / or the second support member 60 to rotate relative to each other toward the second side 10b. Since the first free surface 841 is a curved surface or a slanted surface, or includes both a curved surface and a slanted surface, the first support member 50 can rotate around the rotating shaft 70 without interference from the second limiting surface 85, allowing the first free surface 841 to rotate freely around the rotating shaft 70. When the second included angle B formed between the first support member 50 and the second support member 60 is less than a preset angle threshold, the spacing formed between the first roller 30 and the second roller 40 is less than a second spacing threshold, causing the annular belt 20 wound around the first roller 30 and the second roller 40 to be in the relaxed state, and the user can easily remove the annular belt 20. The preset angle threshold and the second spacing threshold are values preset by the user. Merely by way of example, the preset angle threshold is 90°.

[0093] In some embodiments, the second included angle B formed when the first support member 50 and the second support member 60 rotate relative to each other toward the second side 10b may be 90°. In this case, a side surface of the first support member 50 facing the second side 10b may abut against the second limiting surface 85 of the second support member 60, thereby limiting a rotation angle toward the second side 10b.

[0094] In some embodiments, the first abutting surface 842 is oriented toward the first side 10a, and the first free surface 841 is oriented toward the second side 10b.

[0095] When the annular belt 20 needs to be tensioned, the user adjusts the first support member 50 and / or the second support member 60 to rotate relative to each other toward the first side 10a. When the first abutting surface 842 and the second limiting surface 85 abut against each other, since both the first abutting surface 842 and the second limiting surface 85 have a flat surface structure, the first abutting surface 842 and the second limiting surface 85 press against each other tightly when abutting, and the flat surface structure allows the first abutting surface 842 and the second limiting surface 85 to abut more fully and more stably. The first support member 50 and the second support member 60 form the first included angle A, and the first included angle A is at the first angle. The elastic annular belt 20 presses tightly against the first roller 30 and the second roller 40, and the first support member 50 and the second support member 60, under an elastic restoring force of the annular belt 20, maintain the first included angle A stably at the first angle.

[0096] As shown in FIG. 13, in some embodiments, the second limiting surface 85 includes a second free surface 851 and a second abutting surface 852. The second free surface 851 rotates relative to the first limiting surface 84. The second abutting surface 852 is configured to abut against the first limiting surface 84 to limit the limit position of the relative rotation between the first support member 50 and the second support member 60. The second free surface 851 includes a curved surface and / or a slanted surface. The second abutting surface 852 includes a flat surface. The first limiting surface 84 includes a flat surface. Similar to the relationship between the first abutting surface 842 and the first free surface 841, the second abutting surface 852 protrudes toward the first side 10a relative to the second free surface 851. That is, a distance between at least a portion of the second abutting surface 852 and the rotating shaft 70 is greater than a distance between the second free surface 851 and the rotating shaft 70. When the second free surface 851 is a curved surface, the distance between the second free surface 851 and the rotating shaft 70 may be measured by a radial distance from the rotating shaft 70 to the second free surface 851.

[0097] The second free surface 851 allows the first support member 50 and the second support member 60 to rotate freely toward the second side 10b, so that when the second included angle B formed between the first support member 50 and the second support member 60 is less than the preset angle threshold, the user can easily remove the annular belt 20.

[0098] When the first support member 50 and the second support member 60 rotate relative to each other toward the first side 10a to the first included angle A, the second abutting surface 852 abuts against the first limiting surface 84. This abutment, in cooperation with the annular belt 20, maintains the first included angle A stably at the first angle.

[0099] In some embodiments, the first limiting surface 84 includes the first free surface 841 and the first abutting surface 842, and the second limiting surface 85 includes the second free surface 851 and the second abutting surface 852. The first free surface 841 may rotate relative to the second free surface 851. When the first abutting surface 842 and the second abutting surface 852 abut against each other, the limit position of the relative rotation between the first support member 50 and the second support member 60 is limited. The first free surface 841 includes a curved surface and / or a slanted surface. The first abutting surface 842 includes a flat surface. The second free surface 851 includes a curved surface and / or a slanted surface. The second abutting surface 852 includes a flat surface.

[0100] When the annular belt 20 is replaced, the user adjusts the first support member 50 and / or the second support member 60 to rotate relative to each other toward the second side 10b. The structures of the first free surface 841 and the second free surface 851 allow the first support member 50 and / or the second support member 60 to rotate freely around the rotating shaft 70. When the second included angle B formed between the first support member 50 and the second support member 60 is less than the preset angle threshold, the annular belt 20 is in the relaxed state, and the user can easily remove the annular belt 20.

[0101] When the annular belt 20 needs to be tensioned, the user adjusts the first support member 50 and / or the second support member 60 to rotate relative to each other toward the first side 10a. When the first abutting surface 842 and the second abutting surface 852 abut against each other, since both the first abutting surface 842 and the second abutting surface 852 have a flat surface structure, the first abutting surface 842 and the second abutting surface 852 press against each other tightly. The flat surface structure allows the first abutting surface 842 and the second abutting surface 852 to abut more fully and more stably, thereby causing the first support member 50 and the second support member 60 to form the first included angle A at the first angle, and, under the elastic restoring force of the annular belt 20, maintaining the first included angle A stably at the first angle.

[0102] In some embodiments, as shown in FIG. 12, the first support member 50 includes one or more first rotating portions 51, and the second support member 60 includes one or more second rotating portions 61. The rotating shaft 70 passes alternately through the one or more first rotating portions 51 and the one or more second rotating portions 61. The first limiting surface 84 is disposed on at least one of the one or more first rotating portions 51, and the second limiting surface 85 is disposed on at least one of the one or more second rotating portions 61.

[0103] When the first support member 50 and the second support member 60 rotate relative to each other to the first included angle A, the first limiting surface 84 on the first rotating portion 51 cooperates with the second limiting surface 85 on the second rotating portion 61, and limiting is achieved at a rotation position, which is fast and convenient.

[0104] In some embodiments, the first angle may be greater than or equal to 160°. The second angle may be less than or equal to 150°.

[0105] In some embodiments, the first angle may be greater than or equal to 170°. The second angle may be less than or equal to 90°.

[0106] In some embodiments, an axial direction of the rotating shaft 70, an axial direction of the first roller 30, and an axial direction of the second roller 40 are parallel to each other, and there is an interval between the first roller 30 and the second roller 40. In some embodiments, when the first support member 50 and the second support member 60 rotate relative to each other to any angle, the axial direction of the rotating shaft 70, the axial direction of the first roller 30, and the axial direction of the second roller 40 are all parallel to each other.

[0107] As shown in FIG. 9 and FIG. 10, in some embodiments, a first plane 13 is formed between an axis of the first roller 30 and an axis of the rotating shaft 70, and the first plane 13 is located on the first support member 50. A second plane 14 is formed between an axis of the second roller 40 and the axis of the rotating shaft 70, and the second plane 14 is located on the second support member 60. An included angle formed between the first plane 13 and the second plane 14 and facing the first side 10a is the first included angle A. An included angle formed between the first plane 13 and the second plane 14 and facing the second side 10b is the second included angle B.

[0108] Since the first support member 50 and the second support member 60 have certain thicknesses, the first included angle A and the second included angle B described in the present disclosure may be understood as included angles respectively formed by the first plane 13 and the second plane 14 on the first side 10a and the second side 10b.

[0109] In some embodiments, the first angle formed by the first included angle may be 175°.

[0110] In some embodiments, the annular belt includes the elastic base layer and the cleaning layer disposed on the elastic base layer. The annular belt 20 is elastic.

[0111] In some embodiments, the annular belt itself may possess a certain degree of elastic force. That is, the annular belt may be entirely woven from fabric, which can also provide a certain degree of elasticity.

[0112] In some embodiments, the elastic base layer may be made of rubber. The cleaning layer covering a surface of the elastic base layer may be cleaning velvet, cleaning cloth, a cleaning brush, or the like.

[0113] When the first limiting member 81 abuts against the second support member 60, the annular belt 20 presses tightly against the first roller 30 and the second roller 40, and the first support member 50 and the second support member 60, under the elastic restoring force of the annular belt 20, maintain the first included angle A at the first angle. In some embodiments, the first included angle A may be an included angle less than 180°.

[0114] The elastic restoring force of the annular belt 20 may be transmitted to the first support member 50 and the second support member 60 via the first roller 30 and the second roller 40, so that the first support member 50 and the second support member 60 have a force to continue to rotate relative to each other toward the first side 10a. Because the first limiting members 81 limit the limit position of rotation of the first support member 50 and the second support member 60, the first included angle A of the annular belt 20 may be at the first angle under cooperation of the first limiting members 81.

[0115] In some embodiments, the second roller 40 has a cavity. The cleaning belt assembly 10 further includes a driving motor 90 built in the cavity. The driving motor 90 is configured to drive the second roller 40 to roll.

[0116] In some embodiments, the first roller 30 may be located obliquely above the second roller 40. When the cleaning belt assembly 10 cleans the surface to be cleaned, the second roller 40 presses the annular belt 20 against the surface to be cleaned. For example, the surface to be cleaned is a ground. During cleaning work of the cleaning belt assembly 10, the second roller 40 is close to the ground, and the first roller 30 is located obliquely above the second roller 40.

[0117] The driving motor 90 may be a direct current motor, an alternating current motor, a stepping motor, or the like. An output shaft of the driving motor 90 may coincide with the axis of the second roller 40 to drive the second roller 40 to rotate about the axis of the second roller 40.

[0118] By arranging the driving motor 90 inside the second roller 40, a downward pressure exerted by the cleaning belt assembly 10 on the surface to be cleaned can be maximized, so that the cleaning belt assembly 10 can achieve a better cleaning effect on the ground, and the driving motor 90 can be installed in a hidden manner, so that the structure of the cleaning belt assembly 10 is more compact and simpler. In addition, the driving motor 90 and the second roller 40 may be set as an integrated module for convenient assembly. Furthermore, because the driving motor 90 needs to be arranged inside the second roller 40, a diameter of the second roller 40 needs to be set relatively large, which can improve obstacle-crossing capability of the second roller 40 and achieve cleaning of large-volume garbage.

[0119] FIG. 14 is a schematic diagram of cooperation between a driving motor and a second roller according to some embodiments of the present disclosure.

[0120] As shown in FIG. 14, in some embodiments, the cleaning belt assembly 10 further includes a bracket 94. The driving motor 90 includes a motor body 91, a first drive shaft 92, and a second drive shaft 93.

[0121] The motor body 91 is mounted on the bracket 94. The motor body 91 includes a first end and a second end opposite to each other. The first end and the second end refer to two ends of the motor body 91 in an axial direction of the rotating shaft 70. The first drive shaft 92 is arranged at the first end of the motor body 91. The second drive shaft 93 is arranged at the second end of the motor body 91.

[0122] The second roller 40 includes two second rollers 40. One of the two second rollers 40 is located at the first end of the motor body 91 and is connected to the first drive shaft 92. The other of the two second rollers 40 is arranged at the second end of the motor body 91 and is connected to the second drive shaft 93. The motor body 91 may be connected to the bracket 94. When the cleaning belt assembly 10 works, the driving motor 90 operates to drive the first drive shaft 92 and the second drive shaft 93 to rotate synchronously. The first drive shaft 92 and the second drive shaft 93 respectively drive the two second rollers 40 to rotate.

[0123] The two second rollers 40 are located at opposite ends of the motor body 91. Therefore, interaction forces between the driving motor 90 and the two second rollers 40 are relatively balanced, so that the cleaning belt assembly 10 can operate stably, and the annular belt 20 can also better fit the surface to be cleaned, thereby achieving a better cleaning effect.

[0124] In some embodiments, the cleaning belt assembly 10 further includes the bracket 94. The second roller 40 includes a third end and a fourth end opposite to each other. The third end and the fourth end refer to two opposite ends of the second roller 40 in the axial direction of the rotating shaft 70. The driving motor 90 includes two driving motors 90. The two driving motors 90 are a first driving motor and a second driving motor, respectively. The first driving motor includes a first motor body and a third drive shaft. The second driving motor includes a second motor body and a fourth drive shaft. The first motor body is connected to the bracket 94. The third drive shaft is connected to the third end of the second roller 40. The second motor body is connected to the bracket 94. The fourth drive shaft is connected to the fourth end of the second roller 40. The first driving motor and the second driving motor synchronously drive the second roller 40 to rotate. In some embodiments, the first motor body and the bracket 94 remain stationary, and the second motor body and the bracket 94 remain stationary. During operation, the third drive shaft and the fourth drive shaft rotate to synchronously drive the second roller 40 to rotate.

[0125] The first motor body and the second motor body are located at opposite ends of the second roller 40. Therefore, interaction forces between the driving motors 90 and the second roller 40 is relatively balanced, so that the cleaning belt assembly 10 can operate stably, and the annular belt 20 can also better fit the surface to be cleaned, thereby achieving a better cleaning effect.

[0126] As shown in FIG. 1 to FIG. 3, in some embodiments, the cleaning belt assembly 10 includes the first side 10a and the second side 10b opposite to each other. The included angle formed by the first support member 50 and the second support member 60 toward the first side 10a is the first included angle A. When the first support member 50 and the second support member 60 rotate relative to each other until the first included angle A reaches a third angle, the spacing between the first roller 30 and the second roller 40 is at the first spacing to achieve tensioning of the annular belt 20. When the first support member 50 and the second support member 60 rotate relative to each other so that the first included angle A reaches a fourth angle, the spacing between the first roller 30 and the second roller 40 is less than the second spacing to release tension on the annular belt 20. The fourth angle is less than the third angle.

[0127] It should be noted that the first angle and the second angle are determined based on two different included angles (the first included angle A and the second included angle B, which are oriented toward the first side and the second side, respectively) to determine the tensioned state and the relaxed state of the annular belt. The third angle and the fourth angle are determined based on different values of the same included angle (the first included angle A, i.e., the included angle oriented toward the first side) to determine the tensioned state and the relaxed state of the annular belt.

[0128] The first support member 50 and the second support member 60 may achieve tensioning or release of tensioning of the annular belt 20 by rotating relative to each other toward the first side 10a. In some embodiments, whether the annular belt 20 is in the tensioned state or the relaxed state is determined by an angle of the first included angle A. Because the fourth angle is less than the third angle, when the annular belt 20 is at the fourth angle, the spacing between the first roller 30 and the second roller 40 is closer, and the annular belt 20 surrounding the first roller 30 and the second roller 40 is in the relaxed state, so that the annular belt 20 can be disassembled and replaced.

[0129] When the annular belt 20 is at the third angle, the spacing between the first roller 30 and the second roller 40 is farther, and the annular belt 20 is in the tensioned state.

[0130] In some embodiments, the cleaning belt assembly 10 further includes a third limiting member. When the first support member 50 and the second support member 60 rotate relative to each other until the first included angle A is at the third angle, the third limiting member is configured to fix relative positions of the first support member 50 and the second support member 60.

[0131] When the first included angle A is at the third angle, the annular belt 20 is tensioned. The third limiting member fixes the relative positions of the first support member 50 and the second support member 60, so that the annular belt 20 maintains the tensioned state.

[0132] In some examples, the third limiting member may be a buckle. For example, the third limiting member includes a male buckle arranged on a first connecting frame 11 and a female buckle arranged on a second connecting frame 12. When the male buckle and the female buckle are buckled, the annular belt 20 maintains the tensioned state. When the male buckle and the female buckle are unfastened, the annular belt 20 is in the relaxed state.

[0133] In some examples, according to actual needs, the third limiting member may also be other forms of locking structures.

[0134] As shown in FIG. 7, in some embodiments, an outer wall of each of the first support member 50 and the second support member 60 has a plurality of recesses 15. The recess 15 is configured to reduce material consumption for manufacturing the first support member 50 and the second support member 60, and to reduce an overall weight of the cleaning belt assembly 10.

[0135] By providing the recesses 15, the first support member 50 and the second support member 60 can be lighter and more material-saving, and the cost can be reduced.

[0136] As shown in FIG. 11, in some embodiments, the cleaning belt assembly 10 includes the first side 10a and the second side 10b opposite to each other. The outer wall of the first support member 50 and the outer wall of the second support member 60 each have a plurality of through slots 16. The through slots 16 penetrate from the first side 10a to the second side 10b. The first support member 50 and the second support member 60 each only need to have a skeleton capable of providing support to meet support requirements.

[0137] By providing the through slots 16, the first support member 50 and the second support member 60 can also be lighter and more material-saving, and the cost can be reduced.

[0138] In some embodiments, the first support member 50 further includes a support portion 52. The support portion 52 is sleeved on the first roller 30. The cleaning belt assembly 10 is pressed down against the surface to be cleaned during wiping of the surface to be cleaned. The provision of the support portion 52 can strengthen a connection between the first support member 50 and the first roller 30, making the structure more stable and reliable.

[0139] As shown in FIG. 3 to FIG. 6, in some embodiments, the cleaning belt assembly 10 further includes the first connecting frame 11. The first connecting frame 11 is fixedly connected to the first support member 50. The first connecting frame 11 is rotatably connected to the first roller 30. The cleaning belt assembly 10 further includes the second connecting frame 12. The second connecting frame 12 is fixedly connected to the second support member 60. The second connecting frame 12 is rotatably connected to the second roller 40. Merely by way of example, one of a sleeve and a boss is provided at a portion of the first connecting frame 11 facing the first roller 30, and the other of the sleeve and the boss is provided at an end portion of the first roller 30. The sleeve and the boss are rotatably engaged with each other. A structure of the first connecting frame 11 is similar to a structure of the second connecting frame 12.

[0140] In some embodiments, the cleaning belt assembly 10 may be provided with two first connecting frames 11. The two first connecting frames 11 are respectively connected to two ends of the first roller 30 and correspondingly connected to two sides of the first support member 50. The cleaning belt assembly 10 may be provided with two second connecting frames 12. The two second connecting frames 12 are respectively connected to two ends of the second roller 40 and correspondingly connected to two sides of the second support member 60.

[0141] The provision of the first connecting frame 11 can make the connection between the first roller 30 and the first support member 50 more stable and reliable. Providing the second connecting frame 12 can make a connection between the second roller 40 and the second support member 60 more stable and reliable.

[0142] The present disclosure provides a cleaning apparatus 100 in some embodiments. The cleaning apparatus 100 includes the cleaning belt assembly 10 as described above.

[0143] FIG. 15 is a schematic diagram of an overall structure of a cleaning apparatus according to some embodiments of the present disclosure. FIG. 16 is a partial cross-sectional view of the cleaning apparatus according to some embodiments of the present disclosure.

[0144] As shown in FIG. 15 and FIG. 16, in some embodiments, the cleaning apparatus 100 includes the cleaning belt assembly 10 and a first cleaning auxiliary member 110. The first cleaning auxiliary member 110 is disposed behind the cleaning belt assembly 10 along an advancing direction of the cleaning apparatus 100. The first cleaning auxiliary member 110 is configured to assist the annular belt 20 in cleaning debris.

[0145] In some embodiments, because the annular belt 20 is rotatably wound around the first roller 30 and the second roller 40, the annular belt 20 may carry debris on the surface to be cleaned under an action of friction during rotation, and may pick up and convey the debris with assistance of the first cleaning auxiliary member 110. The cleaning apparatus 100 can achieve thorough cleaning of the surface to be cleaned and ensure the cleaning effect.

[0146] The annular belt 20 wound around the first roller 30 and the second roller 40 forms a conveying side for carrying debris. The first cleaning auxiliary member 110 has a slanted surface corresponding to the conveying side. The conveying side of the annular belt 20 cooperates with the slanted surface of the first cleaning auxiliary member 110 to clamp the debris, and the rotating annular belt 20 may convey the debris without wind power driving.

[0147] In some embodiments, the cleaning apparatus 100 may further include a recovery container 150. The recovery container 150 is configured to receive debris conveyed by the annular belt 20 and the first cleaning auxiliary member 110.

[0148] In some embodiments, the advancing direction of the cleaning apparatus 100 is a main moving direction of the cleaning apparatus 100 during operation.

[0149] Merely by way of example, when the cleaning apparatus 100 is a handheld cleaning apparatus 100 and the surface to be cleaned is a ground, the user needs to hold the cleaning apparatus 100 and push the cleaning apparatus 100 in a direction the user moves forward. This direction is the advancing direction of the cleaning apparatus 100.

[0150] In some embodiments, if the cleaning apparatus 100 is a cleaning robot, the advancing direction is a moving direction of the cleaning robot.

[0151] FIG. 17 is a partial cross-sectional view of a cleaning apparatus according to some other embodiments of the present disclosure.

[0152] As shown in FIG. 17, in some embodiments, the cleaning apparatus 100 includes the cleaning belt assembly 10, a second cleaning auxiliary member 120, and a roller brush member 130.

[0153] The second cleaning auxiliary member 120 is disposed behind the cleaning belt assembly 10 along the advancing direction of the cleaning apparatus 100. The second cleaning auxiliary member 120 is configured to assist the annular belt 20 in cleaning debris.

[0154] The roller brush member 130 is disposed behind the second cleaning auxiliary member 120. The roller brush member 130 is configured to perform at least one of: cleaning the surface to be cleaned, cooperating with the cleaning belt assembly 10 to convey debris, and scraping debris on the cleaning belt assembly 10.

[0155] During execution of cleaning work by the cleaning apparatus 100, the rotating annular belt 20 may adhere to debris on the surface to be cleaned under an action of friction, and may cooperate with the second cleaning auxiliary member 120 and the roller brush member 130 to pick up and convey the debris. A structure and a working principle of the second cleaning auxiliary member 120 are similar to those of the first cleaning auxiliary member 110, and details are not repeated herein.

[0156] When the annular belt 20 conveys the debris to an end of a slanted surface of the second cleaning auxiliary member, the debris is conveyed to a surface of the roller brush member 130. Under rolling of the roller brush member 130, the debris continues to be conveyed into the recovery container 150. The surface of the roller brush member 130 may be close to the conveying side of the annular belt 20. When a rotation direction of the roller brush member 130 is the same as a rotation direction of the annular belt 20, a surface of the roller brush member 130 near the conveying side and the conveying side move in opposite directions. This allows the roller brush member 130 to clean debris on a surface of the first annular cleaning belt timely and prevents the debris from sticking to the surface of the annular belt 20.

[0157] FIG. 18 is a partial cross-sectional view of a cleaning apparatus according to yet some other embodiments of the present disclosure.

[0158] As shown in FIG. 18, in some embodiments, the cleaning apparatus 100 includes the cleaning belt assembly 10 and a third cleaning auxiliary member 140.

[0159] The third cleaning auxiliary member 140 is disposed behind the cleaning belt assembly 10 along the advancing direction of the cleaning apparatus 100. The third cleaning auxiliary member 140 is configured to assist the annular belt 20 in cleaning debris.

[0160] The third cleaning auxiliary member 140 includes an auxiliary annular belt 1401, a third roller 1402, and a fourth roller 1403. The auxiliary annular belt 1401 is rotatably wound around the third roller 1402 and the fourth roller 1403.

[0161] The third roller 1402 and the fourth roller 1403 are configured to cooperate with the auxiliary annular belt 1401 to achieve auxiliary picking and conveying of debris or dirt by utilizing friction.

[0162] The rotating annular belt 20 is configured to adhere to debris on the surface to be cleaned under an action of friction during rotation, and pick up and convey the debris with assistance of the third cleaning auxiliary member 140. A structure and a working principle of the third cleaning auxiliary member 140 are similar to those of the first cleaning auxiliary member 110, and details are not repeated herein.

[0163] The auxiliary annular belt 1401 is rotatably wound around the third roller 1402 and the fourth roller 1403. The auxiliary annular belt 1401 may also clean the surface to be cleaned and convey debris under the action of friction.

[0164] In some embodiments, the cleaning belt assembly 10 is disposed obliquely relative to the surface to be cleaned. The first roller 30 is located obliquely above the second roller 40. A weight of the second roller 40 is greater than a weight of the first roller 30. A diameter of the second roller 40 is greater than a diameter of the first roller 30. When the cleaning apparatus 100 performs a cleaning operation, the second roller 40 presses the annular belt 20 against the surface to be cleaned.

[0165] Because the diameter of the second roller 40 is greater than the diameter of the first roller 30, obstacle-crossing capability of the second roller 40 can be improved, and cleaning of large-volume garbage can be achieved. Because the weight of the second roller 40 is greater than the weight of the first roller 30, the annular belt 20 is pressed down against the surface to be cleaned more effectively. When the annular belt 20 drags and wipes the surface to be cleaned, the friction is greater, and the cleaning effect is better.

[0166] Although the present disclosure is described in detail above in combination with the accompanying drawings and embodiments, it can be understood that the above description does not limit the present disclosure in any form. Those skilled in the art may deform and change the present disclosure as needed without departing from the spirit and scope of the present disclosure. These deformations and changes fall within the scope of the present disclosure.
