The traditional roller brush structure is usually more complicated, which brings higher maintenance difficulty and time cost to users.

[0003] In order to improve the maintenance efficiency of the floor scrubber robot, the latest technical solution tends to design the roller brush into a pull-out disassembly structure. This design allows users to clean, replace or repair the roller brush more easily. Specifically, the pull-out disassembly structure allows users to easily remove the roller brush without professional tools, with simple disassembly operations. This solution greatly reduces the threshold for maintenance and increases the user's maintenance initiative for the floor scrubber robot.

[0035] An embodiment of the present application provides a pull-out roller brush disassembly and assembly structure for a floor cleaning robot, comprising a roller brush extending axially; also comprising a shell, which is axially penetrated to form a cavity, and the roller brush is arranged in the cavity; also comprising a disassembly and assembly mechanism, which is fixedly connected to the roller brush and is located in the shell, and is movably connected to the shell in the radial direction through a locking assembly; when a user presses the locking assembly in the radial direction, the locking assembly is separated from the shell, so that the roller brush fixed to the disassembly and assembly mechanism can be axially pulled out of the cavity.

[0036] The above-mentioned pull-out roller brush disassembly and assembly structure of a floor-cleaning robot presses the pressing part in the locking part, so that the spring drives the two locking parts to contract relative to each other in the radial direction, so that the limiting part is separated from the shell, and the roller brush fixed to the disassembly and assembly mechanism is pulled out in the axial direction. Simple operation and reliable fixing effect are achieved, and the maintenance efficiency of the floor-cleaning robot is improved.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] See also Figure 1-Figure 13The embodiment of the present application provides a pull-out roller brush 10 disassembly and assembly structure 100 of a floor cleaning robot 200, comprising a roller brush 10 extending along the axial direction F1; also comprising a shell 20, which is provided with a cavity 21 along the axial direction F1, and the roller brush 10 is arranged in the cavity 21; further comprising a disassembly and assembly mechanism 30, which is fixedly connected to the roller brush 10 and is located in the shell 20, and is movably connected to the shell 20 along the radial direction F2 through a locking assembly 31; when a user presses the locking assembly 31 along the radial direction F2, the locking assembly 31 is separated from the shell 20, so that the roller brush 10 fixed to the disassembly and assembly mechanism 30 is pulled out of the cavity 21 along the axial direction F1.

[0039] Specifically, the roller brush 10 is a core component of the floor cleaning robot 200 and is used to clean the floor. At the same time, the housing 20 is formed with a cavity 21 along the axial direction F1, and the roller brush 10 is arranged in the cavity 21. The housing 20 provides protection and support for the roller brush 10.

[0040] Furthermore, the disassembly mechanism 30 is fixedly connected to the roller brush 10 and is located inside the housing 20, and is movably connected to the housing 20 along the radial direction F2 through the locking assembly 31. The disassembly mechanism 30 allows the roller brush 10 to be easily installed and disassembled. At the same time, when the user presses the locking assembly 31 along the radial direction F2, the locking assembly 31 is separated from the housing 20, so that the roller brush 10 fixed to the disassembly mechanism 30 is pulled out of the cavity 21 along the axial direction F1. The function of the locking assembly 31 is to ensure the stability and firmness of the roller brush 10 in the housing 20.

[0041] Furthermore, the user can install and remove the roller brush 10 by a simple pressing operation without using complicated tools or steps. At the same time, the locking assembly 31 ensures the stability and firmness of the roller brush 10 in the housing 20, preventing it from loosening or falling off during the cleaning process. In addition, the housing 20 provides protection for the roller brush 10, reduces damage to the roller brush 10 caused by external factors, and prolongs its service life.

[0042] Furthermore, the user first presses the locking assembly 31 to separate the locking assembly 31 from the housing 20. After the locking assembly 31 is separated, the roller brush 10 fixed to the disassembly mechanism 30 is pulled out of the cavity 21 along the axial direction F1. With the above structure, the user can easily install or remove the roller brush 10.

[0043] In summary, home users can use the floor scrubber robot 200 of this structure to clean the floor and replace the roller brush 10 conveniently and quickly. At the same time, commercial places such as hotels and shopping malls can use the floor scrubber robot 200 of this structure to clean large areas of the floor and improve cleaning efficiency.

[0044] In a specific implementation example, the locking assembly 31 includes a locking piece 311, and the two locking pieces 311 are arranged opposite to each other along the radial direction F2, and each of the locking pieces 311 includes a limiting portion 3111, which extends into the limiting groove 24 of the shell 20 along the radial direction F2 and contacts the limiting groove 24 in the axial direction F1; the locking assembly 31 also includes a spring 312, one end of which is connected to one locking piece 311, and the other end is connected to the other locking piece 311.

[0045] Specifically, when the user needs to replace or adjust the roller brush 10, they will press the locking assembly 31 along the radial direction F2. The spring 312 in the locking assembly 31 will be subjected to pressure, causing it to deform elastically. Also, as the spring 312 deforms, the distance between the locking members 311 increases, so that the limiting portion 3111 can be pulled out of the limiting groove 24. This allows the user to easily pull out or insert the roller brush 10 from the housing 20; conversely, when the user releases the pressure, the spring 312 will return to its original state, pulling the locking member 311 back to its original position, maintaining the stability and firmness of the roller brush 10.

[0046] Furthermore, the locking member 311 is the core part of the locking assembly 31, which is relatively arranged along the radial direction F2 to ensure the stability and firmness of the roller brush 10. At the same time, the limiting portion 3111 extends into the limiting groove 24 of the housing 20 along the radial direction F2 and contacts the limiting groove 24 in the axial direction F1. This ensures a stable connection between the locking member 311 and the housing 20, and prevents the roller brush 10 from moving in the axial direction F1.

[0047] Furthermore, one end of the spring 312 is connected to a locking member 311, and the other end is connected to another locking member 311. The function of the spring 312 is to provide elastic force so that the locking assembly 31 can be movably connected along the radial direction F2, so that the user can press the locking assembly 31 along the radial direction F2 to replace or adjust the roller brush 10.

[0048] In a specific implementation example, each of the locking members 311 includes a pressing portion 3112 which is integrally formed with the limiting portion 3111 , one end of the spring 312 is connected to the pressing portion 3112 of one locking member 311 , and the other end of the spring 312 is connected to the pressing portion 3112 of another locking member 311 .

[0049] Specifically, when the user needs to replace or adjust the roller brush 10, they press the locking assembly 31 along the radial direction F2. The pressing force of the user is transmitted to the spring 312 through the pressing portion 3112, causing the spring 312 to deform elastically. As the spring 312 deforms, the distance between the locking members 311 increases, so that the limiting portion 3111 can be pulled out of the limiting groove 24, and the user can easily pull out or insert the roller brush 10 from the housing 20.

[0050] On the contrary, when the user releases the pressure, the spring 312 will return to its original state, pulling the locking member 311 back to its original position, thereby maintaining the stability and firmness of the roller brush 10.

[0051] Furthermore, the pressing portion 3112 is integrally formed with the limiting portion 3111, which makes the structure more compact and stable. At the same time, the pressing portion 3112 is the main contact point for the user to press the locking assembly 31 along the radial direction F2, so it needs to have a certain strength and wear resistance.

[0052] Furthermore, the function of the spring 312 is to provide elastic force so that the locking assembly 31 can be movably connected along the radial direction F2, which is convenient for the user to press the locking assembly 31 along the radial direction F2 to replace or adjust the roller brush 10.

[0053] In a specific implementation example, each of the locking members 311 also includes a plastic portion 3113, and a pressing portion 3112 on one locking member 311 is arranged opposite to a pressing portion 3112 on another locking member 311, and the two plastic portions 3113 are respectively formed on the two locking members 311, and one of the plastic portions 3113 is extended from a side of the pressing portion 3112 close to the other locking member 311; one end of the spring 312 abuts against the plastic portion 3113 of one locking member 311, and the other end of the spring 312 abuts against the plastic portion 3113 of the other locking member 311.

[0054] Specifically, when the user needs to replace or adjust the roller brush 10, they press the locking assembly 31 along the radial direction F2. The pressing force of the user is transmitted to the spring 312 through the plastic portion 3113 in the pressing portion 3112, causing the spring 312 to deform elastically. As the spring 312 deforms, the distance between the locking members 311 increases, so that the limiting portion 3111 can be pulled out of the limiting groove 24, and the user can easily pull out or insert the roller brush 10 from the housing 20.

[0055] On the contrary, when the user releases the pressure, the spring 312 will return to its original state, pulling the locking member 311 back to its original position, thereby maintaining the stability and firmness of the roller brush 10.

[0056] Furthermore, plastic parts 3113 are formed on the pressing parts 3112 of the two locking members 311, respectively. These plastic parts 3113 are arranged opposite to each other and are respectively located on the pressing parts 3112 of the two locking members 311. The function of the plastic parts 3113 is to fix the spring 312 and provide better stability for the locking member 311.

[0057] Furthermore, the function of the spring 312 is to provide elastic force so that the locking assembly 31 can be movably connected along the radial direction F2, which is convenient for the user to press the locking assembly 31 along the radial direction F2 to replace or adjust the roller brush 10.

[0058] In a specific implementation example, each of the pressing portions 3112 includes a connecting portion 3114 and an anti-slip portion 3115 , which are integrally formed with the limiting portion 3111 ; the anti-slip portion 3115 is vertically connected to the connecting portion 3114 and is disposed along the radial direction F2 .

[0059] Specifically, when the user presses the locking assembly 31 along the radial direction F2, the pressing portion 3112 is subjected to pressure and moves along the direction of the limiting portion 3111. The provision of the anti-slip portion 3115 increases the friction of the pressing portion 3112, making it more stable when subjected to pressure.

[0060] On the contrary, when the user releases the pressure, the spring 312 will return to its original state, pulling the two locking members 311 back to their original positions, thereby maintaining the stability and firmness of the roller brush 10 .

[0061] Furthermore, the connecting portion 3114 and the limiting portion 3111 are integrally formed, which makes the connection between the pressing portion 3112 and the limiting portion 3111 more stable.

[0062] Furthermore, the anti-slip portion 3115 is vertically connected to the connecting portion 3114 and is arranged along the radial direction F2. The anti-slip portion 3115 is mainly arranged to increase the friction force of the pressing portion 3112 to prevent it from sliding when subjected to pressure, thereby providing better stability.

[0063] In a specific implementation example, the disassembly and assembly mechanism 30 also includes a fixed seat 32 and a fixed cover 33, which are fixedly connected to the roller brush 10, and the locking assembly 31 is arranged on the fixed seat 32; the fixed cover 33 is connected to the fixed seat 32 by a latch, and the limiting portion 3111 is located between the fixed cover 33 and the fixed seat 32.

[0064] Specifically, the fixing seat 32 is fixedly connected to the roller brush 10, so that the roller brush 10 has a stable support on the fixing seat 32. At the same time, the locking assembly 31 is arranged on the fixing seat 32, so that the locking assembly 31 can be connected to the roller brush 10 through the fixing seat 32.

[0065] Furthermore, the fixing cover 33 is connected to the fixing seat 32 by a latch, so that the fixing cover 33 can be easily connected to and removed from the fixing seat 32. The limiting portion 3111 is located between the fixing cover 33 and the fixing seat 32, so that the limiting portion 3111 can limit the roller brush 10 under the cooperation of the fixing cover 33 and the fixing seat 32.

[0066] In a specific implementation example, the fixed seat 32 also includes a movable groove 321 and a movable hole 322, which are slidably connected to the connecting portion 3114 and are located on a side of the fixed seat 32 that is in contact with the locking member 311; the movable hole 322 is movably connected to the limiting portion 3111 and is located between the fixed seat 32 and the fixed cover 33.

[0067] Specifically, when the user needs to disassemble the roller brush 10, the user presses the locking assembly 31 along the radial direction F2, so that the connecting portion 3114 of the locking assembly 31 slides in the movable groove 321, and the limiting portion 3111 moves in the movable hole 322, so that the locking assembly 31 is separated from the housing 20. The user pulls the roller brush 10 fixed to the disassembly mechanism 30 out of the cavity 21 along the axial direction F1. In addition, during the disassembly process, the design of the movable groove 321 and the movable hole 322 ensures the stability and flexibility of the locking member 311, making the disassembly process smoother.

[0068] Furthermore, the movable groove 321 is slidably connected to the connecting portion 3114 and is located on a side of the fixing seat 32 that is in contact with the locking member 311. This allows the connecting portion 3114 of the locking member 311 to slide in the movable groove 321, thereby achieving movement of the locking member 311.

[0069] Furthermore, the movable hole 322 is movably connected to the limiting portion 3111 and is located between the fixing seat 32 and the fixing cover 33. This allows the limiting portion 3111 to move in the movable hole 322, thereby achieving relative movement between the locking member 311 and the fixing seat 32.

[0070] Furthermore, the provision of the movable groove 321 enables the connecting portion 3114 of the locking member 311 to slide on the fixing seat 32 , thereby increasing the flexibility of the locking member 311 .

[0071] In summary, the movable connection between the movable hole 322 and the limiting portion 3111 can ensure the stability of the locking member 311 on the fixing seat 32 to prevent it from loosening or falling off during the disassembly process.

[0072] In a specific implementation example, it is connected to the opening 2111 of the cavity 21 and is located at one end of the disassembly and assembly mechanism 30; when the user closes the seal 22, the seal 22 covers the opening 2111 of the cavity 21 to limit the roller brush 10 from being pulled out of the cavity 21 along the axial direction F1; when the user opens the seal 22, observing along the axial direction F1, there is no overlapping part between the projection of the seal 22 on the axial direction F1 and the projection of the opening on the axial direction F1, so that the roller brush 10 can be pulled out of the cavity 21 along the axial direction F1.

[0073] Specifically, when the user needs to replace or clean the roller brush 10, the seal 22 is first opened. The projection of the seal 22 in the axial direction F1 does not overlap with the projection of the opening in the axial direction F1, so that the roller brush 10 can be pulled out of the cavity 21 along the axial direction F1. The user can conveniently replace or clean the roller brush 10. When the user completes the operation, the seal 22 is closed to limit the roller brush 10 from being pulled out of the cavity 21 along the axial direction F1.

[0074] Furthermore, the sealing member 22 is connected to the opening 2111 of the cavity 21 and is located at one end of the disassembly and assembly mechanism 30. This allows the sealing member 22 to cover the opening 2111 of the cavity 21, thereby playing a sealing role.

[0075] Furthermore, when the user closes the seal 22, the seal 22 covers the opening 2111 of the cavity 21, limiting the roller brush 10 from being withdrawn from the cavity 21 along the axial direction F1. This ensures the stability of the roller brush 10 during disassembly and assembly, and prevents the roller brush 10 from accidentally falling off or moving.

[0076] Furthermore, when the user opens the seal 22, the projection of the seal 22 in the axial direction F1 does not overlap with the projection of the opening in the axial direction F1, so that the roller brush 10 can be pulled out of the cavity 21 along the axial direction F1. This makes it convenient for the user to replace or clean the roller brush 10.

[0077] In a specific implementation example, the housing 20 further includes a rotation groove 23 , and the rotation groove 23 is rotationally connected to the sealing member 22 .

[0078] Specifically, when the user needs to replace or clean the roller brush 10, the user first opens the seal 22. The user can rotate the seal 22 in the rotation groove 23 to make it more convenient to move away from or approach the disassembly mechanism 30. After adjusting the position, the user can fix the seal 22 by pressing the locking assembly 31 along the radial direction F2. After completing the disassembly operation, the user can rotate the seal 22 in the rotation groove 23 again to return it to the initial position.

[0079] Furthermore, the rotating groove 23 is rotationally connected to the sealing member 22 , so that the sealing member 22 can not only move in the axial direction F1 , but also rotate in the axial direction F1 .

[0080] Furthermore, through the rotation function, the user can more conveniently adjust the position of the seal 22, thereby completing the disassembly and assembly operation more quickly and accurately. At the same time, the rotation connection allows the seal 22 to maintain a tight fit with the housing 20 during rotation, thereby enhancing the sealing effect of the cavity 21.

[0081] Furthermore, the addition of the rotation function makes it more convenient for users to perform disassembly and assembly operations, reducing operation time and difficulty. Through the rotation connection, the seal 22 and the housing 20 fit more closely, thereby improving the overall stability and safety of the floor scrubber robot 200. This design can be applied to more types of floor scrubber robots 200 to meet the needs of different users.

[0082] In a specific implementation example, a rotating shaft 221 is provided on a side of the sealing member 22 that is in contact with the housing 20 , and the rotating shaft 221 is rotatably connected to the rotating groove 23 .

[0083] Specifically, when the user needs to replace or clean the roller brush 10, the seal 22 is first opened. The user can rotate the seal 22 in the rotation groove 23 through the rotation axis 221 to make it more convenient to move away from or approach the disassembly mechanism 30. After adjusting the position, the user can fix the seal 22 by pressing the locking assembly 31 along the radial direction F2. After completing the disassembly operation, the user can rotate the seal 22 in the rotation groove 23 through the rotation axis 221 again to return it to the initial position.

[0084] Furthermore, by providing a rotating shaft 221 on the seal 22, the seal 22 can not only move in the axial direction F1, but also rotate in the axial direction F1. At the same time, through the rotation function, the user can more conveniently adjust the position of the seal 22, thereby completing the disassembly and assembly operation more quickly and accurately. In addition, the rotary connection allows the seal 22 to maintain a close fit with the housing 20 during rotation, thereby enhancing the sealing effect of the cavity 21.

[0085] Furthermore, adding a rotation function makes it more convenient for users to perform disassembly and assembly operations, reducing operation time and difficulty; through the rotation connection, the seal 22 and the shell 20 fit more closely, thereby improving the overall stability and safety of the floor cleaning robot 200; this design can be applied to more types of floor cleaning robots 200 to meet the needs of different users.

[0086] This specific embodiment also provides a floor-cleaning robot 200, including the pull-out roller brush disassembly and assembly structure of the floor-cleaning robot 200.

[0087] By this, the pull-out roller brush 10 disassembly structure 100 of the scrubbing robot 200 provided above presses the pressing portion 3112 in the locking member 311, so that the spring 312 drives the two locking members 311 to relatively contract along the radial direction F2, so that the limiting portion 3111 is separated from the housing 20, and the roller brush 10 fixed to the disassembly mechanism 30 is pulled out along the axial direction F1.
