[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] Please refer to Figure 1 and Figure 2 and combined Figure 3 and Figure 4In one embodiment, a roller brush cleaning device 10 is provided, including a main body 100 and a roller brush module 200. The main body 100 has a roller brush chamber 110 inside. A guide portion 120 is provided on the inner wall of the roller brush chamber 110. The roller brush module 200 includes a guide rail 210, a roller brush body 220, a roller brush support 230, and a roller brush retainer 240. The guide rail 210 is movably engaged with the guide portion 120 along the axial direction of the roller brush body 220, allowing the roller brush module 200 to enter and exit the roller brush chamber 110. The roller brush body 220 has a driven end 221 and a driving end 222 at its two ends along its axial direction. The driven end 221 is rotatably mounted on the roller brush support 230. The driving end 222 passes through the roller brush retainer 240. The guide rail 210 has a first end 211 and a second end 212 disposed opposite to each other along the axial direction of the roller brush body 220. The roller brush bracket 230 is disposed at the first end 211 of the guide rail 210. The roller brush retainer 240 is rotatably disposed at the second end 212 of the guide rail 210. The roller brush retainer 240 can rotate around the second end 212 in a direction closer to or farther from the roller brush body 220 under the action of external force, so as to realize the assembly and disassembly of the roller brush body 220 relative to the roller brush bracket 230.

[0033] In the above embodiment of the roller brush cleaning device 10, when the roller brush body 220 needs to be installed, firstly, the roller brush retainer 240 is driven to rotate around the second end 212 in a direction away from the roller brush bracket 230 to open the roller brush retainer 240. Then, after the driven end 221 of the roller brush body 220 is rotatably mounted on the roller brush bracket 230, the roller brush retainer 240 is driven to rotate around the second end 212 in a direction closer to the roller brush bracket 230 to close the roller brush retainer 240. At this time, the driving end 222 of the roller brush body 220 passes through the roller brush retainer 240 and, under the action of gravity, hangs on the guide rail 210 through the roller brush bracket 230 and the roller brush retainer 240, completing the assembly of the roller brush module 200. Finally, the guide rail 210 is aligned with the guide portion 120 and pushed into the roller brush chamber 110 to realize the assembly of the roller brush cleaning device 10. When it is necessary to disassemble the roller brush body 220, firstly, pull the roller brush module 200 outward from the roller brush chamber 110 along the axial direction of the roller brush body 220 until the guide rail 210 separates from the guide part 120. Then, drive the roller brush retainer 240 to rotate around the second end 212 in a direction away from the roller brush bracket 230 to open the roller brush retainer 240. At this time, the axial limit of the roller brush retainer 240 on the roller brush body 220 is released. Finally, drive the roller brush body 220 to move along its own axial direction to realize the assembly and disassembly of the roller brush body 220 relative to the roller brush bracket 230. In this application, the roller brush body 220 is mounted on the guide rail 210 with the assistance of the roller brush bracket 230 and the roller brush retainer 240, and is detachable relative to the guide rail 210. The guide rail 210 is then movably mounted in the roller brush chamber 110 through the guide part 120, so that the roller brush module 200 can enter and exit the roller brush chamber 110. The operation is simple and convenient, which facilitates the maintenance and replacement of the roller brush body 220 and improves the user experience.

[0034] It should be noted that when the brush retainer 240 is opened, the projection area of ​​the brush retainer 240 is offset from the projection area of ​​the brush body 220 along the axial direction of the brush body 220, so as to ensure that the brush body 220 does not interfere with the brush retainer 240 during its axial movement. Specifically, in this embodiment, the brush retainer 240 is rotated 90° around the second end 212 in a direction away from the brush support 230 to open the brush retainer 240.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the roller brush cleaning device 10 further includes a drive mechanism 300. The drive mechanism 300 is mounted on the main body 100 and is used for transmission connection with the drive end 222. Thus, when the roller brush module 200 is installed in the roller brush chamber 110 along the axial direction of the roller brush body 220, the drive mechanism 300 automatically engages with the drive end 222 of the roller brush body 220, so as to drive the roller brush body 220 to rotate for cleaning, thereby improving the ease of assembly of the roller brush cleaning device 10.

[0036] The drive mechanism 300 can be configured as any structure in the prior art capable of driving the roller brush body 220 to rotate.

[0037] Specifically, in the embodiment of the main body, the roller brush holder 230 has a driven shaft on the side near the roller brush body 220. The driven end 221 of the roller brush body 220 has a first shaft hole that rotatably engages with the driven shaft. The drive mechanism 300 is located at the front end of the main body 100 along the direction from which the roller brush module 200 enters the roller brush chamber 110 and has a drive shaft. The drive end 222 of the roller brush body 220 has a second shaft hole that rotatably engages with the drive shaft.

[0038] like Figure 2 and Figure 3 As shown, optionally, the roller brush retainer 240 has an inner hole for the drive end 222 to pass through. The inner diameter of the inner hole is larger than the outer diameter of the drive end 222, so that when the drive mechanism 300 is connected to the drive end 222, the drive end 222 is separated from the roller brush retainer 240. In this way, when the roller brush module 200 is installed in the roller brush chamber 110, the drive end 222 passes through the inner hole and is spaced apart from the inner wall of the inner hole, avoiding the roller brush retainer 240 from rubbing against the drive end 222 and generating heat when the drive mechanism 300 drives the roller brush body 220 to rotate, thereby reducing the energy consumption of the roller brush cleaning device 10 and improving the reliability of the roller brush cleaning device 10.

[0039] Specifically, in this embodiment, a guide slope is provided at the opening of the second shaft hole. The guide slope is used to guide and cooperate with the drive shaft so that after the drive shaft enters the second shaft hole, it can lift the drive end 222, thereby separating the drive end 222 from the brush retainer 240.

[0040] The guide section 120 can be configured as a guide frame, guide groove or other guide structure.

[0041] like Figure 5 and Figure 6 As shown, in one embodiment, the guide portion 120 is configured as a guide groove. The profile shape of the guide groove along its cross-section perpendicular to its extension direction matches the profile shape of the guide rail 210 along its cross-section perpendicular to its extension direction. Thus, after the roller brush module 200 is installed in the roller brush chamber 110, the guide rail 210 fills the guide groove, and the outer wall of the guide rail 210 smoothly transitions with the inner wall of the roller brush chamber 110, ensuring that the debris thrown up by the roller brush body 220 does not accumulate at the guide rail 210, thereby improving the cleaning effect of the roller brush cleaning device 10.

[0042] The guide rail 210 can be configured with a cross-section in a direction perpendicular to its own axis, such as a T-shape, trapezoid, or dovetail shape, to ensure that the roller brush module 200 can be suspended inside the main body 100.

[0043] like Figure 1 As shown, in one embodiment, the roller brush cleaning device 10 further includes a limiting mechanism 400. The limiting mechanism 400 is movably mounted on the main body 100 or the roller brush module 200 and is used to limit the axial movement of the roller brush module 200 along the roller brush body 220. Thus, when the roller brush module 200 is installed in the roller brush chamber 110, the limiting mechanism 400 can limit the position of the roller brush module 200 relative to the main body 100, ensuring that the drive mechanism 300 can stably and reliably drive the roller brush body 220 to rotate, thereby improving the reliability of the roller brush cleaning device 10.

[0044] The limiting mechanism 400 can be configured as any structure in the prior art that can limit the movement of the brush module 200 relative to the main body 100 along the axial direction of the brush body 220.

[0045] like Figure 1 and Figure 2As shown, optionally, the roller brush chamber 110 has a mounting port 111 on one side for the roller brush module 200 to enter and exit. The limiting mechanism 400 includes a limiting member 410. One end of the limiting member 410 is rotatably mounted on the side of the main body 100 near the mounting port 111, so that the other end of the limiting member 410 can be rotated into the mounting port 111 to engage with the roller brush bracket 230, or can be rotated out of the mounting port 111 to release the engagement with the roller brush bracket 230. Thus, when the roller brush module 200 is installed in the roller brush chamber 110, the limiting member 410 is rotated into the installation port 111 to restrict the roller brush module 200 from moving out of the roller brush chamber 110; when the roller brush module 200 needs to be moved out of the roller brush chamber 110 or needs to enter the roller brush chamber 110, the limiting member 410 is rotated out of the installation port 111 to ensure that the limiting member 410 will not interfere with the roller brush module 200, and the roller brush module 200 can smoothly enter and exit the roller brush chamber 110, improving the practicality of the roller brush cleaning device 10.

[0046] In some embodiments, the limiting mechanism 400 can also be an elastic locking structure, which is mounted on the roller brush module 200. Specifically, it can be mounted on the roller brush bracket 230. Correspondingly, the main body 100 is provided with a positioning part that cooperates with the elastic locking structure. The elastic locking structure may include a locking tongue, a spring, and a slider. The positioning part may be a positioning groove, and the locking tongue is adapted to the positioning groove. The locking tongue extends into the positioning groove under the driving force of the spring to limit the axial movement of the roller brush module 200 relative to the main body 100. When the slider is pushed, the spring moves in the opposite direction, thereby driving the locking tongue out of the positioning groove to release the locking of the roller brush module 200 relative to the main body 100. In some embodiments, the elastic locking structure may include a rotating rod, a torsion spring, and a locking tongue. The locking tongue may be disposed on the rotating rod, and the torsion spring may be disposed on the rotating shaft of the rotating rod. Under the action of the torsion spring, the rotating rod rotates around the rotating shaft, causing the locking tongue to insert into the positioning groove, thereby locking the roller brush module 200 relative to the main body 100. When the rotating rod is driven to rotate in the opposite direction against the force of the torsion spring, it causes the locking tongue to exit the positioning groove, thereby releasing the locking of the roller brush module 200 relative to the main body 100. This ensures that the drive mechanism 300 can stably and reliably drive the roller brush body 220 to rotate, improving the reliability of the roller brush cleaning device 10.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the roller brush cleaning device 10 also includes a waste container 500. The waste container 500 is installed on the front side of the main body 100 and has an opening 510 communicating with the roller brush chamber 110. In this way, with the waste container 500 in front, the roller brush body 220 sweeps the waste in from below, using a method of throwing the waste from above, and guided by the inner wall of the roller brush chamber 110 through the opening 510 and into the waste container 500. The capacity of the waste container 500 can be increased, improving the practicality of the roller brush structure device.

[0048] like Figure 6 As shown, optionally, the top of the roller brush compartment 110 is provided with a hook 130. The hook 130 is used to hook onto the upper edge of the opening 510. In this way, during the assembly and disassembly of the trash can 500, the trash can 500 is always in contact with the main body 100 through the hook 130 for initial positioning and connection, improving the ease of assembly of the trash can 500.

[0049] like Figure 1 As shown, optionally, the roller brush chamber 110 is provided with a locking part. The roller brush cleaning device 10 also includes a locking member 600. The locking member 600 is installed on the waste container 500 and is detachably connected to the locking part. In this way, the waste container 500 can be locked together with the main body 100 by the locking engagement of the locking member 600 and the locking part, ensuring that the waste can stably and reliably enter the waste container 500 for centralized collection under the guidance of the inner wall of the roller brush chamber 110, thereby improving the reliability of the roller brush cleaning device 10.

[0050] The locking element 600 can be configured as a locking buckle, locking hook, locking pin, or other locking structure. The locking part can be configured as a locking opening, locking groove, locking hole, or other locking structure. The number of hooks 130, the number of locking elements 600, and the number of locking parts can all be flexibly adjusted according to actual usage needs.

[0051] In this specific embodiment, the locking member 600 is configured as a locking buckle. The locking part is configured as a locking port that engages with the locking buckle. When the trash box 500 is inserted, the trash box 500 is hung on the hook 130 of the main body 100. At this time, the trash box 500 comes into contact with the main body 100 due to gravity, pushing the trash box 500 inward until the locking buckle on the trash box 500 enters the locking port on the main body 100, thus completing the positioning and locking of the trash box 500.

[0052] like Figure 1 As shown, in one embodiment, the roller brush cleaning device 10 further includes a side brush mechanism 700. The side brush mechanism 700 is mounted on at least one end of the main body 100 along the axial direction of the roller brush body 220. The side brush mechanism 700 is located on the front side of the main body 100. Thus, the side brush mechanism 700 can gather debris from the sides of the main body 100 onto the travel path of the roller brush body 220, improving the cleaning effect of the roller brush cleaning device 10.

[0053] like Figure 1 As shown, optionally, the roller brush cleaning device 10 also includes a baffle 800, which is installed on the rear side of the main body 100. In this way, the baffle 800 can intercept the debris left by the roller brush body 220, thereby improving the cleaning effect of the roller brush cleaning device 10.

[0054] like Figure 1As shown, optionally, the roller brush cleaning device 10 also includes a lifting mechanism 900, which is connected to the main body 100 in a transmission manner. In this way, the lifting mechanism 900 can adjust the ground pressure of the roller brush body 220 by driving the roller brush module 200 to rise and fall through the main body 100, so that the roller brush body 220 can be used for cleaning in different scenarios, thereby improving the practicality of the roller brush cleaning device 10.

[0055] In one embodiment, a cleaning device is provided, including a chassis and a roller brush cleaning device 10, the roller brush cleaning device 10 being mounted on the bottom of the chassis. Thus, the cleaning device includes the roller brush cleaning device 10 and correspondingly possesses the technical effects of the roller brush cleaning device 10, which will not be described in detail here.

[0056] The cleaning equipment can be set as a cleaning robot or a sweeping machine, etc.

[0057] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 application.

[0058] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
