[0024] like Figure 1 As shown, this application provides a roller brush assembly, which includes a roller brush and a cleaning net 200. The roller brush includes a roller 100 and bristles. The bristles are disposed on the roller 100. The roller 100 is mounted on the cleaning net 200. The cleaning net 200 includes a plurality of isolation strips 210. The plurality of isolation strips 210 are arranged along the central axis of the roller 100. A mesh 211 is formed between two adjacent isolation strips 210. The bristles pass through the mesh 211 and contact the surface to be cleaned.

[0025] In one specific embodiment, the roller brush is a key component that directly contacts the surface to be cleaned and performs the cleaning function. The roller 100, serving as a support structure, is a cylindrical component that can rotate around its central axis. The roller brush provides an attachment base for the bristles. The bristles are typically made of a material with a certain degree of elasticity and friction, such as nylon, and are densely distributed on the outer surface of the roller 100. As the roller 100 rotates, the bristles sweep across the surface to be cleaned to remove dust, debris, and other impurities. The cleaning net 200 mainly serves to isolate impurities. The isolation strips 210 are an important component of the cleaning net 200. Several isolation strips 210 are arranged sequentially along the central axis of the roller 100, forming a mesh opening 211 between every two adjacent isolation strips 210. The size and shape of this mesh opening 211 are precisely designed to allow the bristles to pass through. During the operation of the roller brush, hair and other debris entangled on the bristles will be detached from the bristles by the action of the isolation strip 210, thereby preventing hair and other debris from getting tangled on the bristles.

[0026] In summary, the design of the cleaning net 200, its isolation strips 210, and mesh 211 ensures that while the brush bristles are in contact with the surface to be cleaned, hair and other debris are blocked by the isolation strips 210, preventing them from becoming entangled in the bristles. Compared to traditional, simple roller brush assemblies, this significantly reduces problems such as decreased cleaning efficiency and roller brush malfunctions caused by hair entanglement, extends the roller brush's lifespan, and ensures that the roller brush maintains good cleaning performance during long-term use, thereby improving the cleaning effect and user experience of the robot vacuum cleaner.

[0027] like Figure 2 As shown, the isolation strip 210 is an arc shape with an opening, and the roller 100 is located in the arc area of ​​the isolation strip 210.

[0028] In one specific embodiment, the isolation strip 210 is an arc shape with an opening. The curvature of the middle part of the isolation strip 210 matches the surface curvature of the roller 100. The roller 100 is located in the arc region of the isolation strip 210. This structural design allows the isolation strip 210 to better surround the roller 100, so as to improve the isolation effect of the isolation strip 210.

[0029] like Figure 2 As shown, several isolation strips 210 are set at equal intervals.

[0030] In one specific embodiment, the distance between two adjacent isolation strips 210 is kept completely equal. This equal spacing setting has a significant impact on the performance of the roller brush assembly. Since the bristles need to pass through the mesh 211 between the isolation strips 210 to contact the surface to be cleaned, the equally spaced isolation strips 210 ensure that the mesh 211 is evenly distributed, thereby ensuring that the bristles are evenly and orderly distributed on the roller 100. When the roller brush rotates to clean, the force exerted on the surface to be cleaned by each bristle is basically the same, and there will be no uneven distribution of cleaning force. At the same time, the probability of hair and other debris being intercepted by the isolation strips 210 in different areas tends to be consistent, which can more stably play the role of preventing hair entanglement.

[0031] In summary, the evenly distributed mesh 211 allows the bristles to act evenly on the surface to be cleaned, improving the cleaning effect, avoiding cleaning dead spots, and more effectively isolating hair to prevent it from getting tangled on the bristles.

[0032] like Figure 2 As shown, the cleaning net 200 also includes a base 220, which has a through groove 221, and the isolation strip 210 is located at the through groove 221.

[0033] In one specific embodiment, the base 220 is the basic support structure of the cleaning net 200, providing a stable mounting base for the entire cleaning net 200 and the roller brush that works with it. A large-area through groove 221 is provided at the center of the base 220, and the isolation strip 210 is set corresponding to the through groove 221. The through groove 221 is used to make way for the brush bristles, so that the brush bristles can contact the surface to be cleaned.

[0034] In summary, the base 220 provides an installation foundation for the isolation strip 210, while the through groove 221 on the base 220 provides the necessary conditions for the bristles to contact the surface to be cleaned.

[0035] like Figure 2 As shown, the base 220 includes two spaced-apart fixing plates 222, and the roller 100 is located between the two fixing plates 222. The fixing plates 222 are provided with notches 223, which are used to make way for the roller 100.

[0036] In one specific embodiment, a fixing plate 222 is provided on the base 220 at the positions corresponding to both ends of the roller 100. A semi-circular notch 223 is provided on the fixing plate 222. The notch 223 is used for the roller 100 to pass through, and the roller 100 falls into the notch 223, so that the fixing plate 222 supports the roller 100.

[0037] like Figure 2As shown, the cleaning net 200 also includes several fixing strips 230, which are connected to several isolation strips 210 respectively. The fixing strips 230 and the isolation strips 210 form a ring to enhance the structural strength of the cleaning net 200.

[0038] In one specific embodiment, the fixing strip 230 is an important component of the cleaning net 200 used to enhance the overall structural strength. The fixing strip 230 is arc-shaped and is connected to the isolation strip 210 to form a ring structure. From a mechanical perspective, the ring structure has good stability and compressive strength. When the roller brush assembly is subjected to external forces during actual use, the fixing strip 230 and the isolation strip 210, which form the ring, can work together to evenly distribute the external forces and ensure the structural stability of the cleaning net 200.

[0039] In summary, the ring-shaped structure formed by the fixing strip 230 and the isolation strip 210 in the cleaning net 200 enhances the overall structural strength of the cleaning net 200, enabling it to better resist various external impacts and effectively reducing the possibility of damage to the cleaning net 200 caused by external forces.

[0040] like Figure 2 As shown, several fixed strips 230 are set at equal intervals.

[0041] In one specific embodiment, when several fixing strips 230 cooperate with the isolation strips 210 to form a ring, they are arranged at equal intervals. This equal interval arrangement is of great significance to the cleaning net 200. Since the fixing strips 230 and the isolation strips 210 together form a ring structure to enhance the strength of the cleaning net 200, the equally spaced fixing strips 230 can make the ring structure more uniformly stressed when subjected to external forces. When encountering external impact, each fixing strip 230 can evenly share these forces, ensuring the overall stability of the cleaning net 200.

[0042] In summary, the evenly distributed fixing strips 230 make the annular structure of the cleaning net 200 more uniformly stressed when subjected to external forces, which significantly improves the cleaning net 200's ability to resist external impacts.

[0043] like Figure 1 As shown, the roller brush assembly also includes a protective housing 300, which is fixedly assembled with the cleaning net 200 and covers the opening.

[0044] In one specific embodiment, the protective shell 300, as a protective component of the roller brush assembly, is tightly integrated with the cleaning net 200 through specific connection methods such as screw fixing or snap-fit ​​connection, forming a complete protective system. In the cleaning net 200, the isolation strip 210 is an arc-shaped structure with openings, and the main function of the protective shell 300 is to cover these openings. The protective shell 300 can be made of plastic material with certain strength and toughness, and is manufactured using injection molding to a shape that fits the openings of the cleaning net 200. The protective shell 300 can effectively prevent external dust, hair, debris, and other impurities from entering the interior of the cleaning net 200 and the area containing the roller 100 and brush bristles, reducing the possibility of hair and other impurities entering through the openings and becoming entangled in the brush bristles, further enhancing the roller brush assembly's ability to isolate hair and other impurities.

[0045] like Figure 2 As shown, the cleaning net 200 is integrally molded.

[0046] In one specific embodiment, the cleaning net 200 adopts a one-piece molding manufacturing process. This one-piece molding structure makes the cleaning net 200 more integral and the connection between the parts is tighter and more stable. There is no structural instability caused by loose connection parts or gaps. During the use of the roller brush assembly, the one-piece molding cleaning net 200 can better maintain its shape and structure.

[0047] In one specific embodiment, the roller brush assembly further includes a drive motor 400, which is fixedly connected to one end of the roller 100 and is used to drive the roller 100 to rotate.

[0048] In order to achieve the purpose of this utility model, in one embodiment, this application also provides a sweeping robot, which includes the roller brush assembly described in any of the above embodiments.

[0049] In this embodiment, no specific structure of the robot vacuum cleaner is limited, as long as the robot vacuum cleaner includes the above-mentioned roller brush assembly.

[0050] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
