[0030] It should be understood that the specific embodiments described herein are merely intended to explain the utility model, and are not used to limit the utility model.

[0031] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly and specifically defined.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The robotic vacuum cleaner 1 evolved gradually under the inspiration of various devices and technologies. Its evolution process can be summarized as follows: taking the traditional broom and manually propelled sweeping machine as the prototype of cleaning function, borrowing the principle of vacuum cleaner, relying on robotics and sensing technology to achieve autonomous movement and interaction with the environment, and then using artificial intelligence and algorithms to optimize the cleaning path, it has finally developed from a simple cleaning tool into an intelligent device.

[0035] In the actual application scenario of the sweeping robot 1, the sweeping robot 1 usually sweeps debris by the roller brush 110, and a plurality of rows of bristles 1103 are usually arranged on the roller brush 110. After being used for a period of time, hair is entangled between the plurality of rows of bristles 1103, causing the roller brush 110 to be stuck. In the prior art, the traditional solution is that the user manually cleans the hair entangled on the roller brush 110 at regular intervals. This traditional method is not intelligent enough. With the development of technology, other more intelligent solutions have appeared, such as arranging a mechanism for blocking hair on one side of the roller brush 110, or arranging a cutting mechanism for cutting hair, further improving the intelligent degree of the sweeping robot 1.

[0036] However, the utility model person finds that in the prior art, the above-mentioned solutions not only have relatively complex structures and are difficult to maintain, but also have poor actual hair entanglement prevention effect. For example, although the blocking mechanism can prevent the hair from being entangled with the roller brush 110 and avoid the roller brush 110 being stuck, the hair is still entangled on the blocking mechanism and is difficult to clean. For another example, although the cutting mechanism can cut the hair, the density of the blade determines the length of the cut hair, and if the spacing is not appropriate, the hair entanglement problem cannot be solved. In order to more completely solve the technical problem that the roller brush is easily entangled with hair when the sweeping robot 1 sweeps a house, the embodiment of the present application provides a roller brush anti-entanglement structure of a sweeping robot 1. The hair is blocked by the spiral partition 1102 to prevent the hair from being entangled with the plurality of rows of bristles 1103. At the same time, since the spiral partition 1102 and the bristle 1103 are both spiral structures, the hair can be transported from the fixed end 1100 to the free end 1101 during the rotating work of the roller brush 110 and separated from the roller brush 110 at the free end 1101. The hair entanglement with the roller brush 110 can be effectively prevented. The roller brush anti-entanglement structure of the sweeping robot 1 in the embodiment of the present application will be described in detail below in combination with the drawings.

[0037] Please refer to Figures 1 to 9 In the embodiment, a roller brush anti-entanglement structure of a sweeping robot 1 is provided, which comprises a roller brush assembly 11. The roller brush assembly 11 is fixedly installed on a body 10 of the sweeping robot 1. The roller brush assembly 11 comprises a roller brush 110 and a roller brush cover mechanism 111. The roller brush 110 comprises a fixed end 1100 and a free end 1101. A spiral partition 1102 is arranged between the fixed end 1100 and the free end 1101. A plurality of rows of bristles 1103 are arranged between the spiral partitions 1102 correspondingly. The spiral advancing direction of the bristle 1103 is consistent with the spiral advancing direction of the spiral partition. The roller brush 110 is fixedly connected with the roller brush cover 111 through the fixed end 1100.

[0038] In the embodiment, the roller brush assembly 11 is installed on the body 10 of the robot cleaner 1 and used for cleaning the floor when the robot cleaner 1 is working. The roller brush 110 is the part directly contacting the floor, and the bristles 1103 thereon are used for scraping dust, debris and hair and the like. The roller brush cover mechanism 111 is installed on the robot cleaner 1 and covers and protects the roller brush assembly 11, and in particular, the roller brush cover mechanism 111 is fixed on the robot cleaner 1 by bolts, facilitating disassembly, cleaning and replacement. It can be understood that in the embodiment, the fixed end 1100 of the roller brush 110 refers to the first end connected with the body 10, and the free end 1101 refers to the end away from the fixed end 1100 and not connected with the body 10. When the fixed end 1100 is connected with the body 10, the whole roller brush 110 forms a cantilever structure and can rotate freely to clean.

[0039] In the above embodiment, the spiral partitions 1102 are arranged between the fixed end 1100 and the free end of the roller brush 110, and the bristles 1103 are arranged between the spiral partitions 1102. The bristles 1103 are used for cleaning hair during the working process of the roller brush 110, and the spiral partitions 1102 are used for blocking the hair to prevent the hair from winding around the multiple rows of bristles 1103. At the same time, since the spiral partitions 1102 and the bristles 1103 are both spiral structures, and the spiral advancing direction of the bristles 1103 is consistent with the spiral advancing direction of the spiral partitions 1102, the hair can be transported from the fixed end 1100 to the free end 1101 during the rotating working process of the roller brush 110 and separated from the roller brush 110 from the free end 1101, effectively preventing the hair from winding around the roller brush 110.

[0040] In the above embodiment, the spiral partitions 1102 and the bristles 1103 can also be arranged in groups between the fixed end 1100 and the free end 1101. For example, referring to Figure 6 , two spiral partitions 1102 and one row of bristles 1103 form a group of spiral mechanisms, wherein the whole row of bristles 1103 is arranged between the two spiral partitions 1102, and the spiral advancing direction of the bristles 1103 is consistent with the spiral advancing direction of the spiral partitions 1102. The fixed end 1100 of the roller brush 110 is provided with at least two groups of spiral mechanisms, and no bristles 1103 are arranged between the spiral mechanisms.

[0041] For example, referring to Figure 1 and Figure 9In one embodiment, a brush groove 100 is provided on the chassis surface of the body 10, a drive member 12 and a first transmission member 13 are provided inside the body 10, the brush groove 100 is provided with a mounting hole 1000, the roller brush cover mechanism 111 includes a second transmission member 1110, the second transmission member 1110 passes through the mounting hole 1000 and is connected to the first transmission member 13, and the drive member 12 and the first transmission member 13 are connected.

[0042] In this embodiment, the brush groove 100 is a recess located on the chassis of the sweeper, such as... Figure 3 As shown, a mounting position is provided for the roller brush assembly 11, ensuring its stable operation during cleaning and maintaining an appropriate distance from the ground to achieve the purpose of cleaning the floor. The drive unit 12 generates power to drive the roller brush 110 to rotate, and the first transmission unit 13 transmits the power to the roller brush assembly 11. For details, please refer to [link to documentation]. Figure 7 The first transmission component 13 consists of multiple meshing gears, capable of transmitting power while controlling the output torque by changing the number of teeth on the gears. The drive component 12 can be a motor. The mounting hole 1000 is located on one side of the second transmission component, extending outward to form a protrusion, allowing the brush 110 to be installed in the brush groove 100. The first transmission component 13 can pass through the mounting hole 1000 and connect normally with the protrusion and the second transmission component 1110. The second transmission component 1110 is part of the roller brush cover mechanism 111. One end of it is connected to the first transmission component 13 inside the body 10 through the mounting hole 1000, and the other end is connected to the roller brush 110, ensuring effective power transmission. At the same time, since the connection occurs within the mounting hole 1000, it also protects the transmission component from the influence of the external environment, improving the reliability and durability of the system.

[0043] Please see Figures 1 to 9 In one embodiment, the roller brush cover mechanism 111 further includes a roller brush cover frame 1111. The brush groove 100 is provided with a slot at one end away from the mounting hole 1000, and the roller brush cover frame 1111 is provided with a buckle at one end away from the second transmission member 1110. One end of the roller brush cover frame 1111 is inserted into the first transmission member 13 through the second transmission member 1110, and the other end is fastened to the slot through the buckle.

[0044] In this embodiment, the roller brush cover frame 1111 is provided with a threaded through hole, and the brush groove 100 is provided with a corresponding threaded hole on its edge. The roller brush cover frame 1111 and the brush groove 100 are fixedly connected by bolts passing through the threaded through hole and the threaded hole, ensuring that the roller brush cover mechanism 111 remains stable during operation and avoiding positional displacement due to collision or other factors.

[0045] In the above embodiment, before the brush cover frame body 1111 and the brush groove 100 are fixedly connected by bolts passing through the threaded through holes and the threaded holes, the brush assembly 11 is installed on the brush groove 100 of the machine body 11 by the following method; as shown in Figure 7 , one end of the brush cover frame body 1111 is inserted into the gear of the first transmission member 13 through the rotating shaft of the second transmission member 1110 to realize plug-in connection, and the other end is clamped with the clamping groove provided on the brush groove 100 through the buckle provided on the brush cover frame body 1111 to realize the installation of the brush cover frame body 1111 on the machine body 10.

[0046] Please refer to 1 to 9, in an embodiment, the second transmission member 1110 includes a first connecting member 11100 and a second connecting member 11101, one end of the first connecting member 11100 is connected with the first transmission member 13, and the other end is connected with the second connecting member 11101 through a connecting shaft. The fixed end 1100 of the brush 110 is provided with a clamping hole 1106, and the second connecting member 11101 is correspondingly provided with a screw rod 11102, and the brush 110 is clamped with the second connecting member 11101 through the clamping hole 1106 and the screw rod 11102.

[0047] In this embodiment, the middle part of the second transmission member 1110 is connected with the brush frame body through a bearing, so that the second transmission member can rotate relative to the brush frame body, the first end is provided with the first connecting member 11100 for connecting with the first transmission member 13, as shown in Figure 7 , the first connecting member 11100 is a gear, the gear is meshed and connected with the gear in the first connecting member 11100, the first connecting member 11100 is clamped with the rotating shaft in the bearing, which can transmit power to the rotating shaft to make the rotating shaft rotate relative to the brush frame body. The other end of the second transmission member 1110 is provided with the second connecting member 11101 for connecting with the brush 110, as shown in Figure 5 and Figure 7 , the second connecting member 11101 is a structure provided with a screw rod 11102 at one end, the screw rod 11102 is used for adapting to the clamping hole 1106, and the screw rod 11102 can drive the brush 110 to rotate when rotating.

[0048] In the above embodiment, the application does not make specific limitations on the fixed connection mode of the rolling brush cover mechanism 111 and the brush 110. The above mode of arranging the screw rod 11102 on the second connecting piece 11101 is only a preferred embodiment of the application. In actual use, the brush 110, as the core component of the rolling brush cover mechanism 111, is first fixed on the rolling brush cover mechanism 111 to form a whole mechanism, and then is installed on the sweeping robot 1. Therefore, the connection of the rolling brush cover mechanism 111 and the brush 110 only needs to meet the fixed connection of the two, and the brush 110 can rotate relative to the rolling brush cover mechanism 111. Exemplarily, the rolling brush cover mechanism 111 and the brush 110 can also be fixedly connected through bolts, can also be bonded through strong glue, and can also be integrally connected, which are not listed here. It can be understood that the preferred embodiment of the application adopts the structure of arranging the screw rod 11102 on the second connecting piece 11101 and the clamping of the clamping hole 1106, and the whole transmission system adopts a modular design structure, and each component can be independently manufactured and assembled, which is convenient for the maintenance of the brush 110.

[0049] Please refer to Figures 1 to 9 In an embodiment, the rolling brush cover mechanism 111 further comprises a first magnetic member arranged on the rolling brush cover frame body 1111, and the fixed end 1100 of the brush 110 is provided with a second magnetic member 1105. The rolling brush cover frame body 1111 and the brush 110 are magnetically connected through the first magnetic member and the second magnetic member 1105.

[0050] In the embodiment, the second magnetic member 1105 is arranged on the fixed end 1100 of the brush 110 to provide magnetic force. The second magnetic member 1105 is arranged on the brush frame body and cooperates with the second magnetic member 1105 to achieve connection through magnetic force. Specifically, the second magnetic member 1105 can be iron, magnet or other substances with magnetic force, and the first magnetic member can be iron.

[0051] In the above embodiments, the application does not make specific limitations on the fixed connection mode of the rolling brush cover mechanism 111 and the brush 110. In actual use, the brush 110, as the core component of the rolling brush cover mechanism 111, is first fixed on the rolling brush cover mechanism 111 to form a whole mechanism, and then is installed on the robot 1. Therefore, the connection of the rolling brush cover mechanism 111 and the brush 110 only needs to meet the fixed connection, and the brush 110 can rotate relative to the rolling brush cover mechanism 111. Specifically, the rolling brush cover mechanism 111 and the brush 110 can be fixedly connected in a non-detachable manner, or can be fixedly connected in a detachable manner. When the fixed connection is achieved by the detachable connection, the application preferably magnetically connects the first magnetic member and the second magnetic member 1105 to achieve the fixed connection of the two. It can be understood that, by using the magnetic connection mode, the installation process of the brush 110 is simplified when the brush 110 is installed on the rolling brush cover mechanism 111, so that the installation and disassembly of the brush 110 are more convenient and fast. At the same time, the magnetic connection does not need other fasteners, which can reduce mechanical wear and tear, ensure that the brush 110 can be firmly attached to the rolling brush cover body 1111, and avoid loosening or falling off due to vibration or external force during work. When maintenance is needed, the brush 110 can be easily disassembled.

[0052] Please continue to refer to Figures 1 to 9 In an embodiment, the brush groove 100 is provided with a dust suction port 1001, and the dust suction port 1001 is arranged corresponding to the free end 1101 of the rolling brush 110.

[0053] In the embodiment, the dust suction port 1001 is used to suck dust, debris and hair and other substances on the ground. Integrating the dust suction port 1001 into the brush groove 100 makes the whole cleaning system more compact and efficient, while maintaining the simplicity of the appearance of the machine.

[0054] In the above embodiments, the dust suction port 1001 is arranged corresponding to the free end 1101 of the rolling brush 110, which can ensure that the hair, dust and other substances detached from the free end 1101 can be sucked into the dust suction port 1001. It can be understood that the free end 1101 refers to the side of the rolling brush 110 that can rotate freely. Since the partition plate and the bristles 1103 on the rolling brush 110 are both spiral structures, when the rolling brush 110 rotates, it can scrape the hair and other substances from the ground and transfer them from the fixed top end to the free end 1101. When the hair, debris and dust are detached from the free end 1101, they can be sucked into the dust suction port 1001. By aligning the dust suction port 1001 with the free end 1101 of the rolling brush 110, the suction force can be concentrated in the most needed place to ensure the best cleaning effect.

[0055] Please continue to refer to Figures 1 to 9In one embodiment, the roller brush cover mechanism 111 further includes a blocking member 1112 and a blocking cover 1113, wherein the blocking member 1112 is connected to the roller brush cover frame 1111 via the blocking cover 1113.

[0056] In this embodiment, the blocking member 1112 is used to prevent large pieces of garbage or foreign objects from entering the brush groove 100. Simultaneously, the surface of the blocking member 1112 near the roller brush 110 is an arc surface corresponding to the roller brush 110, which can, to a certain extent, prevent small materials such as hair, dust, and debris from being flung out when the roller brush 110 rotates. The blocking cover 1113 is used to connect to and fix the blocking member 1112 to the roller brush cover frame 1111, thus protecting the blocking member 1112. Specifically, the blocking block and the blocking cover 1113 are engaged by a locking block and a locking hole 1106, and the blocking cover 1113 and the roller brush cover frame 1111 are fixedly connected by bolts.

[0057] In the above embodiments, the blocking member 1112 and the blocking cover 1113 also facilitate the maintenance of the roller brush 110. When the roller brush 110 needs to be replaced, the blocking cover 1113 can be removed to replace the roller brush 110 without removing the entire roller brush assembly 11 from the brush groove 100.

[0058] In actual use, the operation steps for installing the roller brush cover mechanism 111 onto the sweeping robot 1 in this embodiment are as follows: First, the brush 110 needs to be installed on the roller brush cover mechanism 111. During installation, the spiral rod 11102 is aligned with the locking hole 1106, and the spiral rod 11102 is inserted into the locking hole 1103. Then, the brush 110 is fixedly connected to the second connector 11101 by the first magnetic component and the second magnetic component 1105. Next, the roller brush cover mechanism 111 needs to be installed on the sweeping robot 1. During installation, the roller brush cover mechanism 111 is installed on the sweeping robot 1 by bolts. Finally, the blocking cover 1113 with the blocking component 1112 is fixedly installed on the roller brush cover mechanism 111 by bolts, thus completing the installation of the roller brush cover mechanism 111.

[0059] Please continue reading. Figures 1 to 9 In one embodiment, the roller brush cover mechanism 111 further includes a limiting member 1114, the brush groove 100 is provided with a limiting hole, and the end of the roller brush mechanism away from the mounting hole 1000 is fixedly connected to the brush groove 100 through the limiting member 1114 and the limiting hole.

[0060] In the embodiment, the limiting piece 1114 is used to limit the movement of the rolling brush assembly 11. It should be noted that during the installation and disassembly of the rolling brush assembly 11, since the rolling brush assembly 11 is fixed on the brush groove 100 by bolts, at the same time, the accurate connection of the first transmission piece 13 and the second transmission piece 1110 and the accurate connection of the rolling brush 110 and the second transmission piece 1110 need to be considered during the installation of the rolling brush assembly 11 and the brush groove 100. If the pre-fixing is not performed during the installation, the position may be deviated, therefore, the limiting piece 1114 is pre-fixed by the limiting piece 1114 before the rolling brush assembly 11 is fastened with the brush groove 100, which can ensure the accuracy of the installation.

[0061] Please continue to refer to Figures 1 to 9 In an embodiment, a spiral groove 1104 is further arranged between the fixed end 1100 and the free end 1101, and the spiral groove 1104 is arranged between the bristles 1103 and the spiral partition 1102.

[0062] In the embodiment, the spiral groove 1104 is used to guide the small particle substances such as dust and debris to the dust suction port 1001. During the rotation, the spiral groove 1104 can guide the dust, debris and other sundries scraped during the cleaning along the spiral path to the dust suction port 1001, so as to ensure that these sundries can be effectively sucked into the dust collection system.

[0063] The anti-winding structure prevents hair winding through the following operation process:

[0064] When the sweeping robot 1 starts to work, the first transmission piece 13 and the second transmission piece 1110 transmit the power of the driving piece 12 to the rolling brush 110, the rolling brush 110 rotates, the bristles 1103 intermittently contact the ground, and the hair is hung on the rolling brush 110; since the spiral partition 1102 is arranged on the rolling brush 110, the hair can be blocked between the spiral partitions 1102, so as to prevent the hair from winding between the multiple rows of bristles 1103. Under the action of rotation, the hair moves along the spiral path from the fixed end 1100 to the free end 1101 of the rolling brush 110, and finally enters the dust suction port 1001.

[0065] In summary, the roll brush anti-winding structure of the sweeping robot 1 according to the embodiment of the application comprises a roll brush assembly 11 fixedly installed on the body 10 of the sweeping robot 1, the roll brush assembly 11 comprising a roll brush 110 and a roll brush cover mechanism 111, the roll brush 110 comprising a fixed end 1100 and a free end 1101, a spiral partition 1102 being arranged between the fixed end 1100 and the free end 1101, and a hair implant 1103 being arranged between the spiral partitions 1102, the roll brush 110 being fixedly connected with the roll brush cover mechanism 111 through the fixed end 1100. The technical solution sets the spiral partitions 1102 between the fixed end 1100 and the free end 1101 of the roll brush 110, and sets the hair implants 1103 between the spiral partitions 1102, so that the hair implants 1103 clean the hair during the working process of the roll brush 110, and the spiral partitions 1102 block the hair, preventing the hair from winding around the multiple hair implants 1103. Meanwhile, since the spiral partitions 1102 and the hair implants 1103 are both spiral structures, and the spiral advancing direction of the hair implants 1103 is consistent with the spiral advancing direction of the spiral partitions 1102, the hair can be transported from the fixed end 1100 to the free end 1101 during the rotating working process of the roll brush 110, and the hair can be separated from the roll brush 110 from the free end 1101, so that the hair winding around the roll brush 110 can be effectively prevented.

[0066] The above description is only preferred embodiments of the application, and does not limit the patent scope of the application, and any equivalent structure or equivalent process transformation according to the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
