Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to cleaning components and cleaning equipment. Background Technology

The fleece fabric quickly absorbs water, while the water-retaining layer further absorbs and retains moisture, enhancing the cleaning ability for liquid contaminants. Simultaneously, the fleece fabric also handles solid contaminants, improving cleaning efficiency and thoroughness. Furthermore, the enhanced water absorption and retention capabilities of the cleaning component increase its absorption efficiency and maximum absorption capacity, preventing water stains from remaining on the cleaned floor. This allows the cleaning component to effectively absorb water and remove dirt without leaving streaks. Moreover, since the water-retaining function is primarily handled by the water-retaining layer, the fleece fabric does not need to retain excessive moisture, allowing for a reduction in the fleece fabric's pile length and faster drying, thus reducing bacterial growth.

[0055] Please see Figures 1 to 10 This application provides a cleaning component 10 and a cleaning device 1 including the cleaning component 10. Specifically, the cleaning device 1 can be a cleaning robot, a floor scrubber, etc., but is not limited to these. Taking a cleaning robot as an example, the cleaning robot is used to clean contaminants on surfaces awaiting cleaning. Please refer to... Figure 1 In this embodiment, the cleaning device 1 includes conventional components of existing cleaning robots, such as a housing and a cleaning component 10, with the cleaning component 10 disposed at the bottom of the housing. When cleaning a surface to be cleaned, such as a floor, the cloth structure 300 of the cleaning component 10 can remove solid contaminants such as dust and hair, as well as liquid contaminants such as sewage. Simultaneously, the water-retaining layer 200 of the cleaning component 10 can further absorb water to remove liquid contaminants such as sewage, thereby effectively improving the cleaning effect.

[0056] See Figure 2 , Figure 3 and Figure 4 The cleaning component 10 includes a support member 100, a water-retaining layer 200, and a fleece structure 300. The support member 100 serves as the basic load-bearing structure, providing structural stability for the entire cleaning component 10. The water-retaining layer 200 is located on the outer surface of the support member 100 and is used to absorb moisture such as water stains and liquid stains on the ground. The fleece structure 300 is located on the side of the water-retaining layer 200 away from the support member 100 and is used to sweep away solid contaminants such as dust, hair, and debris on the ground, as well as absorb moisture. The water retention capacity of the water-retaining layer 200 is greater than that of the fleece structure 300. Water retention capacity refers to the ability to prevent internal moisture from leaking out. For example, water retention capacity can be characterized by a water retention rate. Taking the water-retaining layer 200 as an example, its water retention rate is the percentage of the mass of water retained by the water-retaining layer 200 after it has absorbed water to its saturated water absorption capacity, after treatment under specific conditions. In other words, the higher the water retention rate, the better the water retention capacity. Meanwhile, the fleece structure 300 has good water absorption, which refers to its ability to absorb moisture. For example, water absorption can be characterized by the water absorption rate. The water absorption rate of the fleece structure 300 is the mass or volume of water absorbed by the fleece structure 300 per unit time; that is, the higher the water absorption rate, the better the water absorption.

[0057] The cleaning component 10 utilizes a three-layer structure consisting of a support 100, a water-retaining layer 200, and a fleece structure 300. The fleece structure 300 rapidly absorbs water, while the water-retaining layer 200 further absorbs and retains moisture, enhancing its cleaning ability for liquid contaminants. Simultaneously, the fleece structure 300 also handles solid contaminant removal, improving cleaning efficiency and comprehensiveness. Furthermore, the enhanced water absorption and retention capabilities of the cleaning component 10 increase its absorption efficiency and maximum capacity, preventing water stains from remaining on the cleaned surface. This allows the cleaning component 10 to effectively absorb water and remove dirt without leaving streaks. Moreover, since the water-retaining layer 200 primarily handles water retention, the fleece structure 300 does not need to retain excessive moisture. This allows for a reduction in the length of the fleece fibers, resulting in faster drying and reduced bacterial growth.

[0058] In some embodiments, the cleaning component 10 is a roller-type cleaning component or a track-type cleaning component, and the cleaning component 10 performs cleaning operations by rolling. Taking a roller-type cleaning component as an example, see [link to relevant documentation]. Figure 5 The cleaning device 1 includes a roller support 20 and an end disassembly structure 30. A roller motor is housed within the roller support 20, and the end disassembly structure 30 is fixedly connected to a support member 100 of the cleaning component 10. When installing the cleaning component 10, the support member 100 is fitted over the roller support 20, making the support member 100 and the roller motor drive each other and detachable, allowing the roller motor to drive the cleaning component 10 to rotate. Simultaneously, the end disassembly structure 30 engages with a corresponding portion on the housing of the cleaning device 1 to fix the cleaning component 10 to the housing. When disassembling the cleaning component 10, the connection between the end disassembly structure 30 and the housing of the cleaning device 1 is disconnected, allowing both the end disassembly structure 30 and the cleaning component 10 to be removed. The structures of the roller support 20, the end disassembly structure 30, and the roller motor are existing structures and will not be described in detail here. In this embodiment, the support member 100 and the end detachment structure 30 of the roller cleaning assembly are configured as an integral structure, that is, the cleaning assembly 10 and the end detachment structure 30 are connected as a whole. This whole can be disconnected from the roller bracket 20 and the housing of the cleaning device 1, and can be connected along... Figure 5Remove the component in the direction of the middle arrow to replace the cleaning assembly 10. Alternatively, in other optional embodiments, the support member 100 can be a separate design from the end disassembly structure 30. In this case, the support member 100 can be detachably connected to the end disassembly structure 30, for example, by bolts. This allows the support member 100 to be attached to or removed from the end disassembly structure 30, making the installation and replacement of the cleaning assembly 10 more flexible. Similarly, it can be understood that the installation and replacement method of the tracked cleaning assembly is similar to that of the roller-type cleaning assembly, allowing for convenient installation and replacement of the cleaning assembly 10.

[0059] Furthermore, in some embodiments, see [reference] Figure 4 A water-retaining layer 200 covers the outer surface of the support 100. The material of the water-retaining layer 200 includes at least one of polyvinyl alcohol (PVA), polyethylene glycol, sodium polyacrylate, and polyamide. The selection of these materials gives the water-retaining layer 200 excellent water absorption and retention properties, enabling it to quickly absorb and retain liquid stains on the ground. Simultaneously, it works in conjunction with the fleece structure 300 to achieve comprehensive cleaning functions for both liquid and solid contaminants. For example, when the water-retaining layer 200 is made of polyvinyl alcohol, the presence of numerous hydrophilic hydroxyl functional groups on the molecular side chains and the porous structure of polyvinyl alcohol allow it to absorb and retain a large amount of water, effectively cleaning wastewater. Furthermore, the water-retaining layer 200 possesses a certain degree of rigidity, providing stable support for the fleece structure 300 and ensuring its effective adhesion to the ground, thereby enhancing the cleaning effect.

[0060] Further, see Figure 4In some embodiments, the fleece structure 300 includes a fleece layer 310 and a pile layer 320. The fleece layer 310 covers the outer surface of the water-retaining layer 200, serving to connect the water-retaining layer 200 and the pile layer 320, thereby enhancing the connection stability between the pile layer 320 and the water-retaining layer 200 and preventing the pile layer 320 from falling off after long-term use. For example, the water-retaining layer 200 can be glued to the outside of the support member 100, and the fleece layer 310 can be glued to the outside of the water-retaining layer 200. Of course, the fleece layer 310 can also be directly wrapped around the outside of the water-retaining layer 200 or connected by snap-fit ​​or heat-pressing. The pile layer 320 is located on the side of the fleece layer 310 opposite to the water-retaining layer 200, and the pile layer 320 is composed of a plurality of first pile units 321. Each first pile unit 321 has a first end 3211 and a second end 3212. The first end 3211 of the first pile unit 321 is fixed to the pile layer 310, for example, by adhesive. The second end 3212 of the first pile unit 321 extends freely, allowing it to directly contact the ground. This enables it to adsorb solid pollutants through physical contact methods such as friction, hooking, and entanglement, thereby improving the cleaning function of the pile layer 320.

[0061] Optionally, in some embodiments, at least a portion of the pile layer 310 is woven from yarn. For example, the ends of multiple first pile units 321 can be woven together to form the pile layer 310. Alternatively, the pile layer 310 can be formed by weaving yarn separately, and then multiple first pile units 321 can be fixed to the pile layer 310. The pile layer 310 formed by weaving yarn has good flexibility and water permeability, allowing it to deform slightly with the force applied to the first pile units 321, avoiding stress concentration at the connection between the first end 3211 of the first pile unit 321 and the pile layer 310, and reducing the risk of the first pile unit 321 falling off. Furthermore, moisture can quickly reach the water-retaining layer 200 through the pile layer 310, enhancing the water-retaining layer 200's ability to absorb and retain moisture.

[0062] Optionally, see Figure 6In some embodiments, the cross-sectional area of ​​the first fluff unit 321 remains constant from the first end 3211 to the second end 3212. Specifically, the cross-sectional area of ​​the first fluff unit 321 remains constant from the end fixed to the flock layer 310 to the end that extends freely, that is, the cross-sectional area of ​​the first fluff unit 321 remains constant along its own length direction. Thus, the first fluff units 321 are uniformly distributed along the length direction, which not only ensures the effective adsorption of solid pollutants by the first fluff unit 321, but also improves the continuous absorption capacity of moisture, and allows the absorbed moisture to flow along the second end 3212 of the first fluff unit 321 to the first end 3211 until it is absorbed by the water-retaining layer 200, thereby ensuring the water absorption and retention effect.

[0063] Specifically, in some exemplary embodiments, the first pile unit 321 is cylindrical, making its surface smoother and reducing frictional resistance to the floor during cleaning, thus preventing scratches. This is especially suitable for fine cleaning of sensitive surfaces that are easily scratched. Furthermore, the smooth surface of the first pile unit 321 reduces the adhesion of contaminants, allowing for the removal of residual dust, water stains, and other contaminants by simple wiping or rinsing with water, thereby enhancing its self-cleaning ability.

[0064] For example, in some embodiments, the first pile unit 321 is in the shape of an elliptical cylinder, that is, the cross-section of the first pile unit 321 is elliptical, so that the contact area of ​​the first pile unit 321 is different in different directions, which can adapt to different textures of the ground, such as the longitudinal wood grain of wood flooring, the woven texture of carpet, etc. The elliptical cylinder shape can adaptively adjust its posture along the texture direction, enhancing the ability to hook and remove pollutants in the gaps.

[0065] For example, in some embodiments, the first fluff unit 321 is prismatic in shape. Specifically, the first fluff unit 321 can be configured as a triangular prism, quadrangular prism, or other structure with sharp edges to improve the frictional removal effect of the first fluff unit 321 on stubborn contaminants such as debris. Specifically, the sharp edges of the prism shape can apply concentrated stress to stubborn contaminants such as food residue, making it easier for the contaminants to peel off from the ground. At the same time, the prism shape can increase the contact area with large areas of stubborn stains, so as to effectively clean the contaminants through friction.

[0066] For example, in some embodiments, the first fluff unit 321 is hollow tubular, making it lighter and thus reducing the overall weight of the cleaning assembly 10. Furthermore, the hollow tubular shape gives the first fluff unit 321 a certain degree of deformability, allowing it to adapt to uneven surfaces through slight compression. For instance, at small bumps on the ground, the hollow tubular deformation increases the actual contact area with the ground, preventing the first fluff unit 321 from being partially suspended and missed, thereby improving the cleaning coverage of complex surfaces.

[0067] Optionally, in other embodiments, the cross-sectional area of ​​the first pile unit 321 changes from the first end 3211 to the second end 3212, that is, the cross-sectional area of ​​the first pile unit 321 changes along its own length direction. For example, the cross-sectional area of ​​the first pile unit 321 gradually decreases from the first end 3211 to the second end 3212, or the cross-sectional area of ​​the first pile unit 321 gradually increases from the first end 3211 to the second end 3212, or the cross-sectional area of ​​the first pile unit 321 first decreases and then increases from the first end 3211 to the second end 3212, or the cross-sectional area of ​​the first pile unit 321 first increases and then decreases from the first end 3211 to the second end 3212, or the first pile unit 321 may also be configured to have other non-uniform cross-sectional areas. Therefore, the larger cross-sectional area increases the contact area with the ground, enhancing the removal effect on large areas of water stains, dust, and other pollutants. At the same time, the smaller cross-sectional area enhances the ability to thoroughly clean pollutants in small crevices, thus adapting to different cleaning needs.

[0068] Specifically, in some exemplary embodiments, the first pile unit 321 can be configured as a frustum shape, such that the area of ​​the first end 3211 of the first pile unit 321 is larger than the area of ​​the second end 3212. This results in a larger contact area between the first pile unit 321 and the pile layer 310, which enhances the connection force and reduces the risk of detachment. The free end area of ​​the first pile unit 321 is smaller, and the area shrinkage enhances its adaptability to slightly uneven surfaces. Of course, the frustum shape can also be inverted, i.e., the area of ​​the first end 3211 of the first pile unit 321 is smaller than the area of ​​the second end 3212. In this case, the free end area of ​​the first pile unit 321 is larger, which can more efficiently clean up a large amount of pollutants on the ground.

[0069] For example, in some embodiments, the first pile unit 321 may be configured as a cone shape, such that the area of ​​the first end 3211 of the first pile unit 321 is larger than the area of ​​the second end 3212. The larger area of ​​the first end 3211 can ensure the connection strength with the pile layer 310, and the smaller area of ​​the second end 3212 can extend into the small gaps in the ground for deep cleaning.

[0070] For example, in some embodiments, the first pile unit 321 can be configured as a pyramid shape, such that the area of ​​the first end 3211 of the first pile unit 321 is larger than the area of ​​the second end 3212. This ensures the connection strength with the pile layer 310 while also allowing it to reach into small crevices in the ground for deep cleaning. Furthermore, the edges of the pyramid shape can be swept directionally along the direction of the ground texture, enhancing the hooking force on contaminants within the texture and preventing contaminant residue within the texture.

[0071] For example, in some embodiments, the first pile unit 321 can be configured as a frustum shape. Specifically, when the area of ​​the first end 3211 of the first pile unit 321 is larger than the area of ​​the second end 3212, the first end 3211 can ensure the connection strength with the pile layer 310, and the second end 3212 can extend into small gaps in the ground. At the same time, the end face of the second end 3212 is flat, which has a larger contact area with contaminants for deep cleaning. Furthermore, the edges of the frustum shape can be swept directionally along the direction of the ground texture, enhancing the hooking force on contaminants within the texture and preventing contaminant residue within the texture.

[0072] For example, in some embodiments, the first fluff unit 321 can be configured as a wedge shape, the planar side of the wedge shape can fit tightly against the ground to avoid gaps caused by the arc or polygonal structure, while the wedge tip of the wedge shape can penetrate into the gaps in the ground to hook out contaminants such as dust and hair in the gaps, so as to achieve no dead corners in the corner areas.

[0073] Therefore, the cross-sectional area of ​​the first pile unit 321 varies along its length, giving it both structural stability and cleaning flexibility. This effectively achieves both floor cleaning and crevices cleaning, improving cleaning coverage and effectiveness. It should be understood that the above shape is merely an example; in other optional embodiments, the first pile unit 321 can also be configured with other shapes that vary in cross-sectional area.

[0074] Furthermore, in some embodiments, the first pile unit 321 may be composed of a single pile. The first pile unit 321 composed of a single pile is finer and softer, which can reduce the risk of scratching the surface to be cleaned.

[0075] In other embodiments, the first pile unit 321 may be composed of multiple piles combined together. For example, multiple piles may be bundled or intertwined to form the first pile unit 321, which makes the first pile unit 321 structurally stronger, less prone to breakage during cleaning, and has a larger contact area, making it suitable for large-area cleaning operations.

[0076] Furthermore, in some embodiments, the ratio of the length of the first pile unit 321 to the thickness of the pile layer 310 is 1:0.1 to 1:0.5. For example, the ratio of the length of the first pile unit 321 to the thickness of the pile layer 310 can be any value between 1:0.1, 1:0.15, 1:0.2, 1:0.25, 1:0.3, 1:0.35, 1:0.4, 1:0.45, 1:0.5, or 1:0.1 to 1:0.5. It is understandable that if the ratio of the length of the first pile unit 321 to the thickness of the pile layer 310 is too small, i.e., the thickness of the pile layer 310 is too large, the pile layer 310 occupies a large space, which is not conducive to arranging the first pile unit 321. If the ratio of the length of the first pile unit 321 to the thickness of the pile layer 310 is too large, i.e., the thickness of the pile layer 310 is too small, the connection strength between the first pile unit 321 and the pile layer 310 is insufficient. In this embodiment, the ratio of the length of the first pile unit 321 to the thickness of the pile layer 310 is selected within the above-mentioned suitable range, and the thickness of the pile layer 310 is moderate. This provides sufficient connection strength for the first pile unit 321 to prevent the first pile unit 321 from falling off, while also preventing insufficient space for arranging the first pile unit 321 due to the pile layer 310 being too thick. This facilitates the arrangement of the first pile unit 321 with a reasonable length, so as to ensure the cleaning effect.

[0077] In some embodiments, the ratio of the length of the first fluff unit 321 to the thickness of the water-retaining layer 200 is 1:0.2 to 1:1. For example, the ratio of the length of the first fluff unit 321 to the thickness of the water-retaining layer 200 can be 1:0.2, 1:0.3, 1:0.4, 1:0.5, 1:0.6, 1:0.7, 1:0.8, 1:0.9, 1:1, or any value between 1:0.2 and 1:1. It is understood that if the ratio of the length of the first fluff unit 321 to the thickness of the water-retaining layer 200 is too small, that is, if the thickness of the water-retaining layer 200 is too large, the water-retaining layer 200 occupies too much space, which is not conducive to arranging the first fluff unit 321; if the ratio of the length of the first fluff unit 321 to the thickness of the water-retaining layer 200 is too large, that is, if the thickness of the water-retaining layer 200 is too small, it is difficult to achieve the functions of water absorption and water retention. In this embodiment, the ratio of the length of the first pile unit 321 to the thickness of the water-retaining layer 200 is selected within the above-mentioned suitable range. The thickness of the water-retaining layer 200 matches the length of the first pile unit 321, ensuring that the first pile unit 321 can effectively contact the ground. At the same time, the water-retaining layer 200 can fully absorb and retain the moisture during the cleaning process, which is conducive to improving the cleaning effect.

[0078] Furthermore, if the pile layer 320 uses only long pile, the long pile is prone to getting tangled with debris, hair, and other objects, making it difficult to clean itself properly. It may also scratch the cleaning component 10 and the floor or break the pile, and it is also prone to bacterial growth. If the pile layer 320 uses only short pile, it is difficult to guarantee the effectiveness of pollutant removal.

[0079] See Figure 7 and Figure 8 In some embodiments, the pile layer 320 further includes a plurality of second pile units 322. One end of the second pile unit 322 is fixed to the pile layer 310, and the other end of the second pile unit 322 extends freely. The length of the second pile unit 322 is different from the length of the first pile unit 321. Thus, the difference in length between the first pile unit 321 and the second pile unit 322 forms a pile layer 320 with a combination of short and long piles. While ensuring the cleaning effect of pollutants, the pile layer 320 is also less prone to tangling and pulling during self-cleaning, which is beneficial to improving self-cleaning ability. Moreover, setting short piles can also reduce the environment and conditions for bacterial growth and improve the service life of the cleaning component 10.

[0080] Optionally, in one embodiment, the length of the second fluff unit 322 is greater than the length of the first fluff unit 321. The length difference between the first fluff unit 321 and the second fluff unit 322 forms a fluff layer 320 with varying lengths. The shorter first fluff unit 321 can sweep away contaminants on the surface of the ground, while the longer second fluff unit 322 can reach into the crevices, textures, and other recessed areas of the ground to hook out tiny contaminants such as hair and dust hidden therein. Thus, the first fluff unit 321 and the second fluff unit 322 work together to cover cleaning needs at the same depth, making contaminant removal more thorough and improving the adaptability of the cleaning component 10 to complex ground environments.

[0081] Optionally, in some embodiments, the ratio of the length of the first pile unit 321 to the length of the second pile unit 322 is 1:1.5 to 1:3. For example, the ratio of the length of the first pile unit 321 to the length of the second pile unit 322 can be any value between 1:1.5, 1:1.6, 1:1.8, 1:2, 1:2.2, 1:2.4, 1:2.6, 1:2.8, 1:3, or 1:1.5 to 1:3. In this embodiment, the ratio of the length of the first pile unit 321 to the length of the second pile unit 322 is selected within the above-mentioned suitable range to ensure that the second pile unit 322 can penetrate deep into the gaps without being too long and easily getting tangled with hair or other objects. At the same time, the length of the first pile unit 321 can ensure effective coverage of the ground surface, avoiding the impact on the cleaning effect due to insufficient length causing omissions in the ground surface cleaning.

[0082] See Figure 7and Figure 8 In some embodiments, multiple first pile units 321 are sequentially fixed to the pile layer 310 along a first spiral line H1, and multiple second pile units 322 are sequentially fixed to the pile layer 310 along a second spiral line H2. When the cleaning assembly 10 rolls to perform cleaning operations, the multiple first pile units 321 arranged along the first spiral line H1 gradually rotate and contact the ground. At the same time, the multiple second pile units 322 arranged along the second spiral line H2 also gradually rotate and contact the ground, so that all the first pile units 321 and second pile units 322 can gradually contact the ground in a rotating manner. This avoids the accumulation of adsorbed pollutants due to excessively dense first pile units 321 or second pile units 322 in local areas, or the formation of cleaning dead corners due to excessively sparse first pile units 321 or second pile units 322. Meanwhile, since multiple first fluff units 321 and multiple second fluff units 322 are all spirally arranged, during the rotation cleaning process, the first fluff units 321 and the second fluff units 322 can clean the dirt in the same position alternately. That is, the long and short fluffs are used to clean the same position alternately, which can give full play to the advantages of the long and short fluffs, thereby improving the cleaning effect.

[0083] Furthermore, the first spiral H1 and the second spiral H2 are arranged at intervals along the length of the support member 100 to ensure that the first fluff unit 321 and the second fluff unit 322 do not interfere with each other during rotation, and each of them independently performs the cleaning function along the spiral path, further improving the uniformity and comprehensiveness of cleaning.

[0084] In other embodiments, the first pile units 321 and the second pile units 322 are interleaved, wherein the interleaved distribution means that a plurality of first pile units 321 are dispersed among a plurality of second pile units 322, and correspondingly, a plurality of second pile units 322 are also dispersed among a plurality of first pile units 321. For example, see Figure 9 A second pile unit 322 is provided between two adjacent first pile units 321, and a first pile unit 321 is provided between two adjacent second pile units 322. This staggered distribution allows the first pile units 321 and second pile units 322 of different lengths to be more evenly distributed on the pile layer 310, which helps to give full play to the advantages of each length of pile, thereby improving the cleaning effect of the cleaning component 10 on complex ground environments.

[0085] Furthermore, all first fluff units 321 are equally spaced and all second fluff units 322 are equally spaced, meaning that the spacing between any two adjacent first fluff units 321 is the same and the spacing between any two adjacent second fluff units 322 is the same. This avoids the problem of entanglement with contaminants caused by dense arrangement of fluff of a single length type, and helps to extend the service life of the fluff layer 320.

[0086] Of course, in other alternative embodiments, the spacing between adjacent first pile units 321 may be different, and the spacing between adjacent second pile units 322 may be different. For example, see... Figure 10 The spacing L of adjacent first pile units 321 in the length direction of the support member 100 is greater than the spacing W of adjacent first pile units 321 in the width direction of the support member 100, and the spacing of adjacent second pile units 322 in the length direction of the support member 100 is greater than the spacing of adjacent second pile units 322 in the width direction of the support member 100. It should be understood that Figure 10 The examples shown are merely illustrative; any other spacing arrangements should be considered within the scope of this embodiment. It is understood that when adjacent fluff units have the same spacing, if the fluff units are uniformly and densely distributed in all directions, debris and other contaminants can easily accumulate in the narrow gaps between the fluff units, increasing the difficulty of self-cleaning the cleaning component 10. In this embodiment, the multiple first fluff units 321 and multiple second fluff units 322 are non-uniformly distributed. This avoids contaminants concentrating in localized areas of the fluff layer 320, reduces the entanglement or accumulation of hair and other contaminants, helps maintain cleaning continuity, and reduces the difficulty of self-cleaning the cleaning component 10. Specifically, when the spacing between adjacent fluff units along the length of the support member 100 is greater than the spacing between adjacent fluff units along the width of the support member, that is, the fluff units are more densely distributed circumferentially along the cleaning component 10 and more sparsely distributed axially along the cleaning component 10, the arrangement is more efficient. As the cleaning component 10 rotates, the densely distributed fuzz units along the circumference can effectively clean up debris and other contaminants. When the cleaning component 10 needs to self-clean, the debris and other contaminants trapped on the cleaning component 10 can be discharged through the gaps between the sparsely distributed fuzz units along the axial direction, thereby enhancing the self-cleaning ability of the cleaning component 10.

[0087] In other embodiments, see Figure 11 At least one of the first pile unit 321 and the second pile unit 322 is distributed along a straight line parallel to the length direction of the support member 100. For example, the first pile unit 321 may be distributed along... Figure 11 The dotted lines in the diagram indicate that as the cleaning assembly 10 rolls, multiple first fluff units 321 distributed along the same dotted line can simultaneously contact the ground, and the first fluff units 321 of the same length can evenly cover the ground, ensuring full coverage and avoiding missed areas. For example, second fluff units 322 can also be distributed along... Figure 11 The dotted line distribution in the image can also prevent missed scans. For example, the first fluff unit 321 and the second fluff unit 322 can be along... Figure 11The different dotted lines in the design allow the first and second pile units 321 and 322, which have different lengths, to clean the floor alternately. This not only improves the cleaning effect with long pile but also reduces the environment and conditions for bacterial growth by setting short pile, thus extending the service life of the cleaning component 10.

[0088] In other embodiments, see Figure 12 and Figure 13 At least one of the first fluff unit 321 and the second fluff unit 322 is distributed in a V-shape. For example, the first fluff unit 321 may be distributed along... Figure 12 and Figure 13 The dotted lines in the diagram indicate that the multiple first fluff units 321 are arranged in a roughly V-shape. As the cleaning component 10 rotates, the multiple first fluff units 321 distributed along the same V-shaped dotted line sequentially contact the ground, thereby gathering contaminants near the ends of the cleaning component 10 towards the center for concentrated cleaning. This is especially effective for small contaminants that are difficult to clean; the above arrangement helps to clump these contaminants together for better cleaning results. For example, the second fluff units 322 can also be arranged along... Figure 12 and Figure 13 The V-shaped dashed line distribution in the image can also improve the cleaning effect.

[0089] In other embodiments, see Figure 14 The second pile units 322 are distributed in a honeycomb pattern, and the first pile units 321 are disposed within the honeycomb holes formed by the second pile units 322. The honeycomb frame composed of the longer second pile units 322 can effectively clean large areas of floating dust, long hair and other pollutants on the ground surface. At the same time, the shorter first pile units 321 can introduce pollutants into the honeycomb holes for temporary storage, avoiding the accumulation of pollutants on the pile surface and affecting subsequent cleaning. This can reduce the cleaning frequency of the cleaning component 10 and improve cleaning efficiency.
