Description

Technical Field

[0001] This utility model relates to the field of cleaning, and in particular to a roller brush assembly and cleaning equipment. Background Technology

[0002] In the existing technology, most roller brushes adopt a single roller design, which inevitably leads to situations where cleaning is not thorough or sewage stains remain.

[0003] Only a few manufacturers use the dual-roller design, but its design is very simple, just layers nested together. Long-term use leads to quality issues. Furthermore, due to technical limitations, the cleaning layer and track are integrated, making it impossible to remove the cleaning layer for thorough cleaning. When replacing the cleaning layer, it must be replaced along with the track, resulting in high consumable costs. This causes significant inconvenience for users.

[0004] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Summary of the Invention

[0029] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0030] Please refer to Figure 2-9 ,like Figure 2-9 As shown, on one hand, the present invention provides a roller brush assembly, including a cleaning layer 1, a timing belt 2 and a roller component 3, wherein at least two rollers 30 are provided on the roller component 3; At least two rollers have a first anti-slip surface on their outer surfaces, and the inner wall of the timing belt 2 has a second anti-slip surface 211 that matches the first anti-slip surface of the rollers. The timing belt 2 is fitted onto at least two rollers. An anti-slip structure is provided between the cleaning layer 1 and the timing belt 2.

[0031] In the example, the length directions of both the fixing strip 11 and the mounting groove 221 are perpendicular to the rotation direction of the roller brush assembly.

[0032] In the example, the surface of cleaning layer 1 is provided with roller brush bristles or roller brush strips.

[0033] In the example, at least two rollers are arranged horizontally at their bottoms, and the two rollers support the timing belt and the cleaning layer, so that the side of the cleaning layer closest to the area to be cleaned has a cleaning surface 101.

[0034] Preferably, one end of the sheet-like cleaning layer is attached to the other end using Velcro or steel pins. Of course, this patent is not limited to this, and Velcro or the like can also be used to attach it to the surface of the timing belt 2.

Preferably, the inner synchronous belt 21 and the outer synchronous belt 22 are two synchronous belts of different materials or different hardnesses. Preferably, the hardness of the outer synchronous belt 22 is greater than the hardness of the inner synchronous belt 21. In the example, the outer synchronous belt 22 with higher hardness and the inner synchronous belt 21 with lower hardness are fixedly formed by a process, and the outer synchronous belt 22 and the inner synchronous belt 21 are not detachable; for example, formed by an overmolding or coating process.

[0040] In the example, the second anti-slip surface 211 is disposed on the inner wall of the inner synchronous belt 21. In the example, the second anti-slip surface 211 is provided with a plurality of anti-slip teeth at intervals, and the first anti-slip surface is provided with anti-slip grooves that mesh with the anti-slip teeth, and the first anti-slip surface meshes with the second anti-slip surface 211.

Preferably, protruding strips 12 are provided on both symmetrical sides of the inner wall of the cleaning layer 1. Preferably, a plurality of protruding strips 12 are provided at intervals along the axial direction of the cleaning layer 1. In the example, the length direction of the protruding strips 12 is perpendicular to the axial direction of the cleaning layer 1. In the example, the grooves 223 are trapezoidal, V-shaped, or other shapes, etc., but this patent is not limited to these, with the aim of facilitating and stabilizing installation.

In the example, the extension 321 is integrally provided on the first support member 32.

[0047] like Figure 2-4 As shown, in a preferred embodiment, the quick-release structure includes a magnetic structure. A magnetic element 3211 is provided on the extension 321, and a magnet matching the magnetic element is provided on the cleaning device. The magnetic element 3211 is attracted to the magnet, allowing the roller brush assembly to be detachably attached to the cleaning device.
