Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, specifically to a side brush assembly and a sweeping robot. Background Technology

[0002] Cleaning devices such as robotic vacuum cleaners usually have side brush components at the bottom of the machine. When working, the side brushes are constantly rotating. However, during rotation, debris can easily enter the central area of ​​the side brush components, causing the robotic vacuum cleaner to get stuck or even be damaged.

[0003] Currently, some patents exist to address the aforementioned problems. For example, Chinese patent CN118648827A discloses a side brush assembly and a cleaning device. The side brush assembly includes a base and a side brush component connected to the base. The side brush component includes bristles and a blocking portion. The horizontal projection of the blocking portion coincides with the horizontal projection of the bristles. This blocking portion prevents flexible debris such as hair from entering the base (central area of ​​the side brush component) along the direction of the side brush component. However, because flexible debris such as hair accumulates on the blocking portion, it requires timely cleaning by the user, making it inconvenient to use.

[0004] In addition, current robotic vacuum cleaners generally only clean the outer diameter working surface that the brush bristles contact, and the central area of ​​the side brush component is easily missed during the process.

[0005] In summary, existing technologies have technical problems such as the side brush component's central area being easily missed and debris easily entering the central area of ​​the side brush component during the robot vacuum's cleaning process. Utility Model Content

[0006] This utility model provides a side brush component and a sweeping robot, which effectively solves the technical problems in the prior art where the central area of ​​the side brush component is easily missed and garbage easily enters the central area of ​​the side brush component during the sweeping process.

[0007] On one hand, this utility model provides a side brush assembly, including:

[0008] Base;

[0009] Side brush components, a plurality of said side brush components are arranged in a ring and connected to the outer periphery of the base, extending from the central region to the edge region;

[0010] The side brush component includes a side brush arm and bristles connected to the end of the side brush arm. The upper surface of the side brush arm is provided with a sheet-like bone, which extends from the outer periphery of the base along the side brush arm toward the end.

[0011] The sheet-like bone is inclined, with its surface forming an angle with the horizontal plane, to generate a downward airflow when the side brush rotates.

[0012] In one embodiment, one side of the sheet-like bone is connected to the side brush arm, and the other side of the sheet-like bone is arc-shaped and gradually narrows from the outer periphery of the base to the end of the side brush arm.

[0013] In one embodiment, the length of the side brush arm is shorter than the length of the sheet-like bone, so that the end of the side brush arm forms a notch relative to the sheet-like bone.

[0014] In one embodiment, the side brush arm includes a connecting portion and an extension portion extending outward from the base. The connecting portion is horizontally connected to the base, and the extension portion extends downward from the connecting portion at an angle to the extending direction of the connecting portion.

[0015] In one embodiment, the end of the extension is provided with an opening groove for accommodating the bristles, one end of the bristles is housed in the opening groove, and the other end contacts the cleaning surface.

[0016] In one embodiment, the angle of inclination between the surface of the sheet-like bone and the horizontal plane is 15° to 25°.

[0017] In one embodiment, the number of the side brushes is odd.

[0018] On the other hand, this utility model also provides a sweeping robot, which includes a shell and a side brush assembly as described above. A motor is installed inside the shell, the side brush assembly is disposed at the bottom of the shell, and the base is coaxially connected to the output shaft of the motor so that the motor drives the side brush assembly to rotate.

[0019] In one embodiment, the top of the sheet-like bone is clearance-fitted with the bottom of the outer shell.

[0020] In one embodiment, the bottom of the housing is further provided with an opening compartment for receiving the cleaning material in the guide edge area of ​​the side brush assembly.

[0021] In summary, this invention, by setting plate-shaped ribs on the upper surface of the side brush arm, allows these ribs to rotate simultaneously during the rotation of the side brush assembly. This rotation creates airflow and generates low wind pressure, displacing small dust particles and other debris from the central area of ​​the side brush assembly towards the edges. Furthermore, due to the inclined arrangement of the plate-shaped ribs, the resulting airflow is downward, further discharging particles from the central area of ​​the side brush assembly towards the working surface for cleaning. This invention solves the problem of side brush bristles only cleaning the outer diameter of the area where they contact the ground, leaving the central area easily missed during operation. Simultaneously, the outward and downward airflow prevents flexible debris such as hair from becoming entangled and entering the central area of ​​the side brush assembly. This solves the technical problem of debris easily entering the central area of ​​the side brush assembly during the cleaning process of a robotic vacuum cleaner. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] The following description is provided to enable any person skilled in the art to implement and use this invention. Details are set forth in this description for purposes of explanation. It should be understood that those skilled in the art will recognize that this invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this invention with unnecessary detail. Therefore, this invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.

[0031] Example 1

[0032] refer to Figure 1 and Figure 2 This utility model provides a side brush assembly 20, including: a base 21 and side brush members 22. A plurality of side brush members 22 are arranged in a ring around the outer periphery of the base 21 and extend from the central region to the edge region. Each side brush member 22 includes a side brush arm 221 and bristles 222 connected to the end of the side brush arm 221. The upper surface of the side brush arm 221 is provided with a sheet-like bone 226, which extends from the outer periphery of the base 21 along the side brush arm 221 to the end. The sheet-like bone 226 is inclined and its surface forms an angle with the horizontal plane to generate a downward airflow when the side brush member 22 rotates.

[0033] refer to Figure 1 and Figure 2 During the rotation of the side brush assembly 20, the sheet-like ribs 226 on the upper surface of the side brush arm 221 rotate simultaneously. This rotation drives airflow, creating a small air pressure that displaces fine dust and other particles from the central area of ​​the side brush assembly 20 towards the edges. Simultaneously, due to the inclined arrangement of the sheet-like ribs 226, the resulting airflow is downward, thus displacing particles from the central area of ​​the side brush assembly 20 towards the working surface for cleaning. (Reference) Figure 2 In this invention, when the side brush 22 rotates clockwise, the plate-shaped ribs 226 rotate clockwise to generate airflow, which can discharge small dust particles and other particulate matter in the central area of ​​the side brush assembly 20 to the edges and below. This solves the problem that the bristles 222 of the side brush assembly 20 can only clean the outer diameter of the area where the bristles 222 contact the ground, and the central area is easily missed during operation. At the same time, the outward and downward airflow can prevent flexible debris such as hair from getting entangled and entering the central area of ​​the side brush assembly 20, thus solving the problem that debris easily enters the central area of ​​the side brush assembly 20 during the cleaning process of the robot vacuum cleaner.

[0034] In one embodiment, one side of the sheet-like bone position 226 is connected to the side brush arm 221, and the other side of the sheet-like bone position 226 is arc-shaped, gradually narrowing from the outer periphery of the base 21 to the end of the side brush arm 221. The sheet-like bone position 226 is arranged in a leaf shape and gradually narrows in width. During rotation, it can generate a certain centrifugal force on flexible debris such as hair, discharging the flexible debris such as hair from the central area of ​​the side brush assembly 20.

[0035] In one embodiment, the length of the side brush arm 221 is shorter than the length of the sheet-like bone 226, so that the end of the side brush arm 221 forms a notch 225 relative to the sheet-like bone 226. When the sheet-like bone 226 rotates, it generates centrifugal force to push flexible debris such as hair towards the edge area. Since the notch 225 is formed at the end of the side brush arm 221 relative to the end of the sheet-like bone 226, the pushed-out flexible debris such as hair will not re-enter the end of the side brush arm 221, thereby further preventing flexible debris such as hair from entering the central area of ​​the side brush assembly 20.

[0036] In one embodiment, the side brush arm 221 includes a connecting portion 223 and an extension portion 224 extending outward from the base 21. The connecting portion 223 is horizontally connected to the base 21, and the extension portion 224 extends downward from the connecting portion 223, forming an angle with the extending direction of the connecting portion 223. The connecting portion 223 of the side brush arm 221 extends outward in a horizontal direction, while the extension portion 224 extends downward to facilitate contact between the bristles 222 and the cleaning surface. In this application, the connecting portion 223 and the extension portion 224 can be an integrally formed structure. The integral forming process refers to completing the forming process of the entire part in one mold at a time, which has the advantages of low manufacturing cost, simple process, and high processing efficiency.

[0037] In one embodiment, in order to reduce the connection gap between the sheet-like bone position 226 and the side brush arm 221 and enhance the airflow generated during rotation, the sheet-like bone position 226 and the side brush arm 221 may also adopt an integral molding structure.

[0038] The base 21 and the side brush arm 221 can be connected by means of clips, screws, or by welding or integral molding.

[0039] In one embodiment, the extension has an opening groove at its end for accommodating the bristles 222. One end of the bristles 222 is housed in the opening groove, and the other end contacts the cleaning surface. The ends of the bristles 222 are used to contact the cleaning surface to clean debris in the edge area of ​​the side brush assembly 20.

[0040] In one embodiment, the inclination angle between the surface of the sheet-like bone position 226 and the horizontal plane is 15° to 25°. Those skilled in the art can set the inclination angle of the sheet-like bone position 226 according to the required airflow.

[0041] In one embodiment, the number of side brushes 22 is odd. If the number of side brushes 22 is even and they are arranged symmetrically, resonance may occur between the side brushes 22 at a certain rotational speed. This resonance not only leads to excessive noise but may also cause the side brushes 22 to be unable to withstand excessive vibrational energy and become damaged. In contrast, an odd number of side brushes 22, due to their asymmetrical arrangement, can effectively avoid resonance, improving stability and reliability. Furthermore, since the side brushes 22 need to rotate at high speed, poor dynamic balance during rotation can lead to increased vibration, affecting the lifespan of the side brushes 22. An odd number of sheet-like bristles 226 can distribute airflow more evenly during rotation, reducing airflow interference and vortex phenomena caused by the symmetrical arrangement of the sheet-like bristles 226.

[0042] Example 2

[0043] This utility model also provides a sweeping robot, which includes a housing 10 and a side brush assembly 20 as described above. A motor is installed inside the housing 10, the side brush assembly 20 is disposed at the bottom of the housing 10, and the base 21 is coaxially connected to the output shaft of the motor so that the motor drives the side brush assembly 20 to rotate.

[0044] In one embodiment, the top of the sheet-like rib 226 is clearance-fitted with the bottom of the housing 10. This prevents the sheet-like rib 226 from interfering with the bottom of the housing 10 during rotation. The size of the gap 227 can be set to ensure sufficient air can be drawn into the central region and expelled.

[0045] In one embodiment, the bottom of the outer casing 10 is further provided with an opening compartment 11 for receiving the cleaning material in the guide edge area of ​​the side brush assembly 20. The cleaning material includes particulate matter such as dust and flexible debris such as hair.

[0046] Since the side brush component 20 disclosed in the above embodiments is used, the sweeping robot has the corresponding technical advantages of the side brush component 20. Those skilled in the art can refer to the technical advantages of the side brush component 20 in the above embodiments to understand this embodiment, and will not be repeated here.

Specific examples have been used to illustrate the principle and embodiments of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
