[0002] To improve cleaning efficiency, some cleaning equipment on the market is specifically designed for automatically cleaning the walls of sinks. These devices are typically equipped with rotating roller brushes, which utilize the interference friction between the rotating brush and the surface to be cleaned to achieve cleaning. Existing roller brushes are generally designed with the ideal flatness of the sink wall as a given, and their structure is suitable for cleaning flat surfaces.

[0003] However, most pools use ceramic tiles for their bottom and walls, inevitably leaving gaps between them. Existing roller brush designs are flawed, failing to balance the gentleness of surface cleaning with the intensity required to clean these gaps. Insufficient cleaning force leads to inadequate cleaning of the tile gaps, causing dirt to accumulate and negatively impacting water quality. Conversely, excessive cleaning force can damage the tile surface and overload the roller brush, negatively affecting its lifespan. Utility Model Content

[0040] Please see Figures 1 to 4This utility model provides a multifunctional roller brush 20 and a cleaning device 100 incorporating it. The cleaning device 100 is designed for efficient cleaning of various types of pools, such as landscape pools, fish ponds, and especially swimming pools—pools that are frequently used and have high hygiene requirements. In these pools, the pool wall surface forms the surface to be cleaned. However, due to construction processes such as tile splicing, gaps inevitably form in the pool wall surface. These gaps often become hiding places for dirt, and traditional cleaning methods are insufficient to thoroughly remove the grime.

[0041] Specifically, the cleaning device 100 includes a body 10 and a roller brush 20, and the roller brush 20 is rotatable around the body 10 about a rotating shaft 23. Generally, the cleaning device 100 is also provided with a drive mechanism, which drives the roller brush 20 to clean, so that the roller brush 20 contacts the surface to be cleaned, thereby achieving the purpose of scraping and removing stains from the surface of the surface to be cleaned.

[0042] Please continue reading. Figures 5 to 8 The roller brush 20 provided by this utility model is a multi-functional roller brush 20, which can not only clean the surface to be cleaned during rotation, but also simultaneously and with high intensity clean the recessed tile grout and other areas on the surface to be cleaned.

[0043] Specifically, the roller brush 20 includes a rotating shaft 23, a first cleaning member 21, and a second cleaning member 22. The first cleaning member 21 is disposed on the rotating shaft 23 and extends radially outward from the circumference of the rotating shaft 23, and has a first cleaning portion 210 for contacting the surface to be cleaned. The second cleaning member 22 is disposed on the rotating shaft 23 or the first cleaning member 21, and extends radially outward from the circumference of the rotating shaft 23, and has a second cleaning portion 220 for contacting the surface to be cleaned. It can be understood that through the structural design of the second cleaning member 20, multiple second cleaning portions 220 can be distributed in a plurality.

[0044] In an optional embodiment, the second cleaning part 220 is smaller in size in the second direction than the first cleaning part 210. Preferably, multiple second cleaning parts 220 are provided and spaced apart in the second direction. More preferably, the size of the second cleaning part 220 in the second direction is less than or equal to 2 mm. Thus, during operation, the smaller second cleaning part 220, due to its smaller size in the second direction, can reach into the tile grout lines, thereby cleaning away dirt from the grout lines and achieving precise cleaning of the grout area.

[0045] In an optional embodiment, the outer end of the second cleaning member 22 in the radial direction at least partially extends beyond the first cleaning member 21. That is, the maximum length of the second cleaning member 22 in the radial direction is greater than that of the first cleaning member 21. When the cleaning device 100 is working, as the rotating shaft 23 rotates, the first cleaning member 21 is mainly responsible for scraping the surface of the tile to perform surface cleaning, while the second cleaning member 22 extends into the gap between the tiles to simultaneously perform gap depth cleaning.

[0046] In another optional embodiment, the second cleaning member 22 has a greater radial bending stiffness than the first cleaning member 21. That is, when the cleaning device 100 is operating, as the shaft 23 rotates, the first cleaning member 21 has a smaller bending stiffness, resulting in greater deformation when scraping the tile surface and relatively less cleaning force. In contrast, the second cleaning member 22 has a larger bending stiffness, resulting in less deformation when scraping and allowing for deeper cleaning into the tile grout lines. In a parallel embodiment, the second cleaning member 22 can simultaneously employ a dual design of extended length and enhanced stiffness.

[0047] It is understood that the above-mentioned multiple implementation methods can be implemented individually or in combination.

[0048] In this embodiment, by differentiating geometric dimensions or material properties, the roller brush 20 can simultaneously perform surface cleaning and deep cleaning of crevices. This reduces damage to the tiles during surface cleaning and enhances the removal of stubborn stains in crevices, improving cleaning efficiency while reducing wear and tear on the roller brush 20 and extending the overall service life of the cleaning equipment 100.

[0049] Based on the previous embodiment, the first cleaning component 21 is mainly used to achieve surface contact with the surface to be cleaned. Therefore, in this embodiment, the first cleaning component 21 includes a plurality of cleaning protrusions 212, and the end of each cleaning protrusion 212 away from the rotating shaft constitutes the first cleaning part 210. The plurality of cleaning protrusions 212 are distributed circumferentially at intervals on the periphery of the rotating shaft 23, and the length direction of each cleaning protrusion 212 extends axially. In this embodiment, the axially extending protrusion design can cover a large area of ​​cleaning, and the circumferentially spaced structure facilitates the discharge of dirt carried by water flow, reducing the retention on the surface of the protrusions. Preferably, the cleaning protrusions 212 are made of elastic materials such as rubber or silicone, thereby adapting to slightly uneven surfaces and improving the cleaning fit. In this embodiment, the length direction of the cleaning protrusions 212 extending axially means that the cleaning protrusions 212 are approximately parallel to the axial direction, or the circumferential angle between them and the axial direction is less than or equal to 45 degrees.

[0050] Based on the previous embodiment, the second cleaning component 22 can take various forms, as long as it can reach deep into the tile grout lines. In an optional embodiment, please refer to... Figure 5 and Figure 6The second cleaning component 22 includes a plurality of brush bundles 221, each brush bundle 221 being composed of multiple bristles, and the end of each bristle away from the rotating shaft forming a second cleaning section 220. The plurality of brush bundles 221 are distributed at intervals around the rotating shaft 23.

[0051] In this embodiment, the dispersed structure of multiple bristles can conform to the inner wall of the crevice from different angles, and the ends of multiple bristles increase the contact area, improving the dirt-grabbing ability. Preferably, the bristles are made of nylon, which has a higher hardness than the cleaning protrusions 212 made of rubber or silicone. The hardness of nylon material allows the bristles to penetrate deep into the bottom of the crevice, effectively scraping away stubborn dirt in the crevice, and is especially suitable for removing mud, algae, etc. from the crevice.

[0052] Preferably, the multiple brush bundles 221 are distributed in multiple rows along the circumference. In each row of brush bundles 221, the multiple brush bundles 221 are spaced apart along the axial direction, and the multiple rows of brush bundles 221 and the multiple cleaning protrusions 212 are arranged alternately along the circumference. In this embodiment, the alternating arrangement of the cleaning protrusions 212 and the rows of brush bundles 221 ensures uniform coverage of the cleaning area during rotation, achieving a synergistic effect where the cleaning protrusions 212 first remove large dirt from the surface, and the brush bundles 221 then penetrate into the crevices for secondary cleaning. The circumferential alternating arrangement makes surface cleaning and crevic cleaning spatially complementary, avoiding excessive wear on a single component. The spacing design between the brush bundles 221 reduces mutual interference between them, improves rotational flexibility, and ensures that each row of brush bundles 221 can independently penetrate into the corresponding crevices, improving the cleaning effect.

[0053] In another alternative embodiment, please refer to [reference needed]. Figure 5 , Figure 7 and Figure 8 The second cleaning component 22 includes cleaning ribs 222, which extend spirally around the circumference of the rotating shaft 23 along their length. In this embodiment, the second cleaning component 22 is designed as a thin sheet, allowing it to reach deep into crevices for cleaning. The spiral extension design generates an axial pushing force when the roller brush 20 rotates, scraping dirt from the crevices and actively guiding it to the tile surface for easy absorption. Simultaneously, the spiral trajectory allows for multiple cleanings of the same crevices, improving the thoroughness of the cleaning.

[0054] Preferably, each of the cleaning protrusions 212 is segmented in the axial direction, and a groove 213 is defined between every two adjacent segments of the cleaning protrusions 212 in the axial direction. The groove 213 extends spirally around the rotating shaft 23. One end of the cleaning rib 222 near the rotating shaft 23 is disposed in the groove 213, and there is a gap between the two sides of the cleaning rib 222 and the corresponding cleaning protrusions 212 in the axial direction. In this embodiment, the design of the groove 213 provides installation space for the cleaning rib 222 and provides gaps to guide water flow carrying dirt to the suction port, reducing the retention of dirt on the surface of the roller brush 20. Preferably, the cross-section of the groove 213 can be arc-shaped to reduce water flow resistance and improve dirt conveying efficiency.

[0055] Based on the above embodiments, the first cleaning component 21 and the second cleaning component 22 are integrated and detachably mounted on the rotating shaft 23. This allows the user to easily disassemble the first cleaning component 21 and the second cleaning component 22, facilitating cleaning or replacement and improving maintenance efficiency.

[0056] Specifically, please refer to Figures 6 to 8 The first cleaning component 21 includes a sleeve 211, and the second cleaning component 22 is disposed on the outer periphery of the sleeve 211. The sleeve 211 is detachably fitted onto the outer periphery of the rotating shaft 23. This sleeve 211 structure enables the detachable installation of the first cleaning component 21 and the second cleaning component 22 with the rotating shaft 23. The inner wall of the sleeve 211 may be provided with a keyway or thread to engage with the rotating shaft 23, thereby restricting the circumferential movement of the first cleaning component 21 and the second cleaning component 22 relative to the rotating shaft 23.

[0057] Preferably, the cleaning protrusions 212 and brush bundles 221 are integrally molded on the outer wall, which can be achieved using silicone molding or rubber injection molding processes, thereby facilitating overall disassembly for cleaning or replacement of modules made of different materials. In this embodiment, the integrated structure ensures that the cleaning components work together, avoiding the decrease in cleaning efficiency caused by assembly gaps in a split structure.

[0058] Preferably, both the first cleaning component 21 and the second cleaning component 22 are made of silicone or rubber, and are integrally molded. This utilizes the elasticity of silicone / rubber to adapt to the uneven surfaces to be cleaned. In this embodiment, the high elasticity of silicone / rubber buffers the impact during cleaning, preventing scratches on the inner wall of the sink. The integral molding process reduces connection gaps, preventing dirt from accumulating in the assembly gaps and improving cleaning reliability. Simultaneously, the integrally molded first cleaning component 21 and second cleaning component 22 are easy to assemble and disassemble together, improving maintenance efficiency.

[0059] In another optional embodiment, the first cleaning component 21 is made of rubber or silicone. The elastic material of the first cleaning component 21 contacts the tile surface, facilitating relatively gentle, large-area cleaning of the tile surface. The second cleaning component 22 is made of nylon. In this embodiment, the high rigidity of nylon enhances the cleaning power in crevices, making it suitable for cleaning stubborn stains such as algae and silt within crevices. This embodiment's roller brush 20, designed with a combination of materials, balances the gentleness of surface cleaning with the intensity of crevic cleaning. The elastic rubber or silicone material protects the tile glaze, while the high-rigidity nylon cleaning layer specifically removes stains from crevices, reducing damage to the tile during surface cleaning while effectively removing stubborn stains from crevices. This improves cleaning efficiency while reducing wear and tear on the roller brush 20, extending the overall service life of the cleaning equipment 100.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
