In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0034] The robot vacuum cleaner 1 has evolved gradually under the inspiration of various devices and technologies. Its evolution process can be summarized as follows: with traditional brooms and human-driven vacuum cleaners as the prototype of cleaning functions, it draws on the principles of vacuum cleaners, relies on robot technology and sensor technology to achieve autonomous movement and interaction with the environment, and then relies on artificial intelligence and algorithms to optimize the cleaning path, and finally develops from a simple cleaning tool to an intelligent device.

[0035] In the actual application scenario of the sweeping robot 1, the sweeping robot 1 usually uses a roller brush 110 to clean up debris. The roller brush 110 is usually provided with multiple rows of planted hair 1103. After a period of use, there is a problem that hair is entangled between the multiple rows of planted hair 1103, causing the roller brush 110 to get stuck. In the prior art, the traditional solution is that the user manually cleans the hair entangled on the roller brush 110 regularly. This traditional method is not intelligent enough. With the development of technology, other more intelligent solutions have emerged, such as providing a mechanism for blocking hair on one side of the roller brush 110, and providing a cutting mechanism for cutting hair, which further improves the intelligence of the sweeping robot 1.

[0036] However, the inventors have found that the above-mentioned existing solutions are not only relatively complex in structure and difficult to maintain, but also have poor actual anti-entanglement 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 from getting stuck, it will be entangled on the blocking mechanism and is still difficult to clean. For another example, although the cutting mechanism can cut hair, the setting density of the blades determines the length of the hair cutting, and the setting spacing is not appropriate, which also cannot solve the problem of hair entanglement. In order to more thoroughly solve the technical problem that the roller brush of the sweeping robot 1 is easily entangled with hair when cleaning the house, the embodiment of the present application provides a roller brush anti-entanglement structure of the sweeping robot 1, which blocks the hair by a spiral spacer 1102 to prevent the hair from being entangled in the multiple rows of implanted hair 1103. At the same time, since the spiral spacer 1102 and the implanted hair 1103 are both spiral structures, the hair can be transported from the fixed end 1100 to the free end 1101 during the rotation of the roller brush 110, and detached from the roller brush 110 from the free end 1101, which can effectively prevent the hair from being entangled in the roller brush 110. The anti-entanglement structure of the roller brush of the sweeping robot 1 in the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 9 In the present embodiment, a roller brush anti-entanglement structure of a sweeping robot 1 is provided, including a roller brush assembly 11, wherein the roller brush assembly 11 is fixedly mounted on a body 10 of the sweeping robot 1, wherein the roller brush assembly 11 includes a roller brush 110 and a roller brush cover mechanism 111, wherein the roller brush 110 includes a fixed end 1100 and a free end 1101, wherein a spiral spacer 1102 is disposed between the fixed end 1100 and the free end 1101, wherein planted hairs 1103 are correspondingly disposed between the spiral spacers 1102, wherein the spiral advancing direction of the planted hairs 1103 is consistent with the spiral advancing direction of the spiral spacers, and the roller brush 110 is fixedly connected to the roller brush 110 cover via the fixed end 1100.

[0038] In this embodiment, the roller brush assembly 11 is installed on the body 10 of the sweeping robot 1, and is used for the sweeping robot 1 to clean the floor when it is working. The roller brush 110 is the part that directly contacts the ground, and the implanted hair 1103 thereon is used to scrape away dust, debris, hair and other garbage. When the roller brush cover mechanism 111 is installed on the sweeping robot 1, it covers and protects the roller brush assembly 11, and is used to protect the roller brush assembly 11. Specifically, the roller brush cover mechanism 111 is fixed to the sweeping robot 1 by bolts, which is convenient for disassembly, cleaning and replacement. It can be understood that in this embodiment, the fixed end 1100 of the roller brush 110 refers to the first end connected to the body 10, and the free end 1101 refers to the end away from the fixed end 1100 and not connected to the body 10. When the fixed end 1100 is connected to the body 10, the entire roller brush 110 forms a cantilever structure, which can rotate freely for cleaning. The spiral spacer 1102 is located between the fixed end 1100 and the free end 1101, and the hair transplantation 1103 is arranged between the spiral spacer 1102. The spiral spacer 1102 separates the hair transplantation 1103 to play a separating role, which can prevent the long limiting materials such as hair from being entangled on the entire roller brush.

[0039] In the above embodiment, a spiral spacer 1102 is arranged between the fixed end 1100 and the free end of the roller brush 110, and hair transplantation 1103 is arranged between the spiral spacer 1102. During the operation of the roller brush 110, the hair transplantation 1103 is used to clean the hair, and the spiral spacer 1102 is used to block the hair to prevent the hair from being entangled with the multiple rows of hair transplantation 1103. At the same time, since the spiral spacer 1102 and the hair transplantation 1103 are both spiral structures, and the spiral forward direction of the hair transplantation 1103 is consistent with the spiral forward direction of the spiral spacer 1102, during the rotation of the roller brush 110, the hair can be transported from the fixed end 1100 to the free end 1101 and detached from the roller brush 110 from the free end 1101, which can effectively prevent the hair from being entangled with the roller brush 110.

[0040] In the above embodiment, the spiral spacer 1102 and the implanted hair 1103 can also be arranged in groups between the fixed end 1100 and the free end 1101. For example, please refer to Figure 6 The two spiral spacers 1102 and a row of implanted hairs 1103 form a set of spiral mechanisms, wherein a whole row of implanted hairs 1103 is arranged between the two spiral spacers 1102, and the spiral advancing direction of the implanted hairs 1103 is consistent with the spiral advancing direction of the spiral spacers 1102. The fixed end 1100 of the roller brush 110 is provided with at least two sets of spiral mechanisms, and no implanted hairs 1103 are arranged between the spiral mechanisms.

[0041] See also Figure 1 and Fig. 9In one embodiment, a brush groove 100 is provided on the chassis surface of the body 10, a driving 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 driving member 12 and the first transmission member 13 are connected.

[0042] In this embodiment, the brush groove 100 is a groove located on the chassis of the sweeper. Figure 3 As shown, it is used to accommodate the roller brush assembly 11 and provide an installation position for the roller brush assembly 11 to ensure that it can work stably during the cleaning process and can maintain an appropriate distance from the ground to achieve the purpose of cleaning the ground. The driving member 12 can generate power to drive the roller brush 110 to rotate, and the first transmission member 13 is used to transmit the power to the roller brush assembly 11. For details, please refer to Figure 7 The first transmission member 13 is a plurality of gears meshing with each other, which can transmit power and control the output torque by changing the number of teeth of the gears. The driving member 12 can be a motor. The mounting hole 1000 is located on one side of the second transmission member, and partially extends outward to form a boss, so that after the brush 110 is installed in the brush groove 100, the first transmission member 13 can pass through the mounting hole 1000 and connect normally with the protrusion and the second transmission member 1110. The second transmission member 1110 is a part of the roller brush cover mechanism 111, one end of which is connected to the first transmission member 13 inside the body 10 through the mounting hole 1000, and the other end is connected to the roller brush 110, ensuring the effective transmission of power. At the same time, since the connection occurs in the mounting hole 1000, the transmission member is also protected from the influence of the external environment, thereby improving the reliability and durability of the system.

[0043] See also Figures 1 to 9 In one embodiment, the roller brush cover mechanism 111 also includes a roller brush cover frame 1111, a card slot is provided at one end of the brush slot 100 away from the mounting hole 1000, a buckle is provided at one end of the roller brush cover frame 1111 away from the second transmission member 1110, one end of the roller brush cover frame 1111 is plugged into the first transmission member 13 through the second transmission member 1110, and the other end is buckled and connected to the card slot through the buckle.

[0044] In this embodiment, a threaded through hole is provided on the roller brush cover frame 1111, and a threaded hole is correspondingly provided on the edge of the brush groove 100. 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, thereby ensuring that the roller brush cover mechanism 111 remains stable during operation and avoiding position displacement due to collision or other factors.

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

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

[0047] In this embodiment, the second transmission member 1110 is connected to the roller brush frame through a bearing in the middle, so that the second rotating member can rotate relative to the roller brush frame, and a first connecting member 11100 is provided at the first end for connecting with the first transmission member 13. Figure 7 As shown, the first connecting member 11100 is a gear, which is meshed with the gear in the first connecting member 11100. The first connecting member 11100 is engaged with the rotating shaft in the bearing, which can transmit power to the rotating shaft so that the rotating shaft rotates relative to the roller brush frame. The other end of the second transmission member 1110 is provided with a second connecting member 11101 for connecting with the roller brush 110. For details, please refer to Figure 5 and Figure 7 The second connecting member 11101 is a structure with a spiral rod 11102 at one end. The spiral rod 11102 is used to adapt to the clamping hole 1106. When the spiral rod 11102 rotates, it can drive the roller brush 110 to rotate.

[0048] In the above embodiment, the present application does not impose any specific restrictions on the fixed connection method of the roller brush cover mechanism 111 and the brush 110. The above method of setting the spiral rod 11102 on the second connecting member 11101 is only a preferred embodiment of the present application. In actual use, the brush 110, as the core component of the roller brush cover mechanism 111, is first fixed on the roller brush cover mechanism 111 to form an integral mechanism, and then installed on the sweeping robot 1. Therefore, the connection between the roller brush cover mechanism 111 and the brush 110 only needs to satisfy the requirement that the two are fixedly connected, and the brush 110 can rotate relative to the roller brush cover mechanism 111. Exemplarily, the roller brush cover mechanism 111 and the brush 110 can also be fixedly connected by bolts, or bonded by strong glue, or connected as one piece, which are not exhaustive here. It is understandable that the present embodiment preferably adopts the structure of setting the spiral rod 11102 on the second connecting member 11101 and engaging it with the clamping hole 1106 . The whole transmission system adopts a modular design structure, and each component can be manufactured and assembled independently, so as to facilitate the maintenance of the brush 110 .

[0049] See also Figures 1 to 9 In one embodiment, the roller brush cover mechanism 111 also includes a first magnetic component, which is arranged on the roller brush cover frame 1111. The fixed end 1100 of the roller brush 110 is provided with a second magnetic component 1105. The roller brush cover frame 1111 and the roller brush 110 are magnetically connected through the first magnetic component and the second magnetic component 1105.

[0050] In this embodiment, the second magnetic member 1105 is arranged at the fixed end 1100 of the roller brush 110 to provide magnetic force. The second magnetic member 1105 is arranged on the roller brush frame, and cooperates with the second magnetic member 1105 to achieve connection through magnetic force. Specifically, the second magnetic member 1105 can be a material with magnetic force such as iron or magnet, and the first magnetic member can be iron.

[0051] In the above embodiments, the present application does not impose any specific restrictions on the fixed connection method between the roller brush cover mechanism 111 and the brush 110. In actual use, the brush 110, as the core component of the roller brush cover mechanism 111, is first fixed on the roller brush cover mechanism 111 to form an integral mechanism, and then installed on the sweeping robot 1. Therefore, the connection between the roller brush cover mechanism 111 and the brush 110 only requires that the two are fixedly connected, and the brush 110 can rotate relative to the roller brush cover mechanism 111. Specifically, the roller brush cover mechanism 111 and the brush 110 can be fixedly connected by a non-detachable connection method, or by a detachable connection method. When a detachable connection is used to achieve fixed connection, the present application preferably uses a magnetic connection between the first magnetic member and the second magnetic member 1105 to achieve fixed connection between the two. It is understandable that the use of magnetic connection simplifies the installation process of the brush 110 when the brush 110 is installed on the roller brush cover mechanism 111, making the installation and removal of the brush 110 more convenient and quick; at the same time, the magnetic connection does not require other fasteners, which can reduce mechanical wear and ensure that the brush 110 can be firmly attached to the roller brush cover frame 1111 to avoid loosening or falling off due to vibration or external force during operation. The brush 110 can be easily removed when maintenance is required.

[0052] Please continue reading Figures 1 to 9 In one 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 roller brush 110 .

[0053] In this embodiment, the suction port 1001 is used to suck up dust, debris, hair and other materials on the ground. The suction port 1001 is integrated into the brush groove 100, making the entire cleaning system more compact and efficient while maintaining the simplicity of the appearance of the machine.

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

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

[0056] In this embodiment, the blocking member 1112 is used to prevent large pieces of garbage or foreign matter from entering the brush groove 100. At the same time, the surface of the blocking member 1112 close to the roller brush 110 is a curved surface corresponding to the roller brush 110, which can prevent small objects such as hair, dust and debris from being thrown out when the roller brush 110 rotates to a certain extent. The blocking cover 1113 is used to connect with the roller brush cover frame 1111 and fix the blocking member 1112, so as to protect the blocking member 1112. Specifically, the blocking block and the blocking cover 1113 are clamped by the clamping block and the clamping hole 1106, and the blocking cover 1113 and the roller brush cover frame 1111 are fixedly connected by bolts.

[0057] In the above embodiment, the blocking member 1112 and the blocking cover 1113 are also provided to facilitate the maintenance of the roller brush 110. When the roller brush 110 needs to be replaced, only the blocking cover 1113 needs to be removed to replace the roller brush 110. There is no need to remove the entire roller brush assembly 11 from the brush groove 100.

[0058] In actual use, the operating steps of this embodiment for installing the roller brush cover mechanism 111 on the sweeping robot 1 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 card hole 1106, and the spiral rod 11102 is inserted into the card hole 1103, and then the brush 110 is fixedly connected to the second connecting member 11101 through the first magnetic member and the second magnetic member 1105; then, 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 equipped with the blocking member 1112 is fixedly installed on the roller brush cover mechanism 111 by bolts to complete 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 this embodiment, the limiter 1114 is used to limit the movement of the roller brush assembly 11. It should be noted that during the installation and disassembly process of the roller brush assembly 11, since the roller brush assembly 11 is fixed to the brush groove 100 by bolts, at the same time, when the roller brush assembly 11 and the brush groove 100 are installed, it is necessary to consider the precise connection between the first transmission member 13 and the second transmission member 1110, and the precise connection between the roller brush 110 and the second transmission member 1110. If they are not pre-fixed during installation, the position is easily offset. Therefore, the limiter 1114 is pre-fixed by the limiter 1114 before the roller brush assembly 11 and the brush groove 100 are fastened, which can ensure the accuracy of the installation.

[0061] Please continue reading Figures 1 to 9 In one embodiment, a spiral groove 1104 is further provided between the fixed end 1100 and the free end 1101 , and the spiral groove 1104 is provided between the implanted hair 1103 and the spiral spacer 1102 .

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

[0063] The anti-tangle structure prevents hair from getting tangled by the following operation process:

[0064] When the sweeping robot 1 starts to work, the first transmission member 13 and the second transmission member 1110 transmit the power of the driving member 12 to the roller brush 110, and the roller brush 110 rotates, and the implanted hair 1103 is intermittently in contact with the ground, and the hair is hung on the roller brush 110; since the roller brush 110 is provided with a spiral spacer 1102, the hair can be blocked between the spiral spacers 1102 to prevent the hair from being entangled between multiple rows of implanted hair 1103. Under the action of rotation, the hair moves along a spiral path from the fixed end 1100 of the roller brush 110 to the free end 1101, and finally enters the suction port 1001.

[0065] In summary, a roller brush anti-entanglement structure of a sweeping robot 1 according to an embodiment of the present application includes a roller brush assembly 11, which is fixedly mounted on a body 10 of the sweeping robot 1. The roller brush assembly 11 includes a roller brush 110 and a roller brush cover mechanism 111. The roller brush 110 includes a fixed end 1100 and a free end 1101. A spiral spacer 1102 is provided between the fixed end 1100 and the free end 1101. Planted hairs 1103 are correspondingly provided between the spiral spacers 1102. The roller brush 110 is fixedly connected to the roller brush 110 cover via the fixed end 1100. The technical solution sets a spiral spacer 1102 between the fixed end 1100 and the free end of the roller brush 110, and a hair transplant 1103 is set between the spiral spacer 1102. During the operation of the roller brush 110, the hair is cleaned by the hair transplant 1103, and the hair is blocked by the spiral spacer 1102 to prevent the hair from being entangled with multiple rows of hair transplants 1103. At the same time, since the spiral spacer 1102 and the hair transplant 1103 are both spiral structures, and the spiral forward direction of the hair transplant 1103 is consistent with the spiral forward direction of the spiral spacer 1102, during the rotation of the roller brush 110, the hair can be transported from the fixed end 1100 to the free end 1101 and detached from the roller brush 110 from the free end 1101, which can effectively prevent the hair from being entangled with the roller brush 110.
