[0038] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0039] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0040] The brush assembly 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] like Figures 1-8 As shown, the roller brush assembly 1 according to an embodiment of the present utility model includes a roller brush 100 and a handle 200.

[0042] The handle 200 includes a handle 210 and a connector 220. The connector 220 is rotatable relative to the handle 210, and the roller brush 100 is detachably connected to the connector 220. The inner walls of the connector 220 and the roller brush 100 are respectively provided with mutually cooperating snap-fit ​​grooves 111 and elastic snap-fit ​​parts 230, and the elastic snap-fit ​​parts 230 snap-fit ​​into the snap-fit ​​grooves 111.

[0043] The inner walls of the connector 220 and the roller brush 100 are respectively provided with mutually cooperating snap-fit ​​grooves 111 and elastic snap-fit ​​portions 230. This means that the connector 220 is provided with snap-fit ​​grooves 111 and the inner wall of the roller brush 100 is provided with elastic snap-fit ​​portions 230, or the connector 220 is provided with elastic snap-fit ​​portions 230 and the inner wall of the roller brush 100 is provided with snap-fit ​​grooves 111.

[0044] The roller brush 100 may include an inner cylinder 110 and an outer roller brush body 120. The inner cylinder 110 may be constructed as a hollow tubular structure, and a locking groove 111 may be constructed on the side wall of the inner cylinder 110. The locking groove 111 may penetrate the inner cylinder 110 radially, and an elastic locking portion 230 may be constructed on the side wall of the connector 220; alternatively, the locking groove 111 may be constructed on the side wall of the connector 220, and the elastic locking portion 230 may be constructed on the side wall of the inner cylinder 110. Furthermore, the outer roller brush body 120 wraps around the outside of the inner cylinder 110, so that when the inner cylinder 110 rotates about the rotation axis, the outer roller brush body 120 may rotate with the inner cylinder 110 to clean the cleaning surface.

[0045] In addition, the handle 200 can be provided at one end of the roller brush 100 in the axial direction, and the snap-fit ​​groove 111 can be adjacent to the side of the roller brush 100 facing the handle 200. In this way, the snap-fit ​​groove 111 can be closer to the handle 200, that is, the snap-fit ​​groove 111 can be closer to the elastic snap-fit ​​part 230, so as to facilitate the snap-fit ​​assembly of the elastic snap-fit ​​part 230 and the snap-fit ​​groove 111.

[0046] According to the embodiment of the present utility model, the roller brush assembly 1 has a locking groove 111 and an elastic locking part 230 that cooperate with each other on the inner walls of the connector 220 and the roller brush 100, respectively. In this way, the elastic locking part 230 can be locked into the locking groove 111 to realize the locking connection between the connector 220 and the roller brush 100. That is, the handle 200 and the roller brush 100 can be detachably connected.

[0047] Specifically, when the elastic locking part 230 is engaged in the locking groove 111, it ensures a stable connection between the roller brush 100 and the handle 200. When the elastic locking part 230 disengages from the locking groove 111, the roller brush 100 and the handle 200 can be separated, allowing the roller brush 100 and the handle 200 to be disassembled. The structure is reasonably designed, making it convenient for users to replace the roller brush 100 without having to replace the handle 200 and the roller brush 100 together. The handle 200 can be reused multiple times, which helps reduce the replacement cost of the roller brush 100 and provides a better user experience.

[0048] Furthermore, the handle 200 and the roller brush 100 are detachably assembled by engaging the elastic snap-fit ​​part 230 with the snap-fit ​​groove 111. This not only makes assembly and disassembly convenient and quick, but also provides greater stability. Compared to the positioning assembly in related technologies, the connection stability between the roller brush 100 and the handle 200 in this application is higher. That is, during normal use of the roller brush assembly 1, separation of the roller brush 100 and the handle 200 can be avoided, making the roller brush assembly 1 more stable and reliable in use, and providing a better user experience.

[0049] Thus, according to the embodiment of the present utility model, the handle 200 and the roller brush 100 of the roller brush assembly 1 are connected by the elastic snap-fit ​​part 230 and the snap-fit ​​groove 111, which not only realizes the detachable connection between the handle 200 and the roller brush 100, but also ensures the connection stability between the handle 200 and the roller brush 100, making disassembly and assembly convenient and the use more stable and reliable.

[0050] In some specific embodiments of this utility model, such as Figure 8 As shown, there are multiple elastic snap-fit ​​parts 230, and the multiple elastic snap-fit ​​parts 230 are provided on the radially opposite sides of the connector 220 or the radially opposite sides of the inner wall of the roller brush 100. There are multiple snap-fit ​​grooves 111, and the multiple elastic snap-fit ​​parts 230 are snapped into the multiple snap-fit ​​grooves 111 in a one-to-one correspondence.

[0051] For example, multiple elastic snap-fit ​​portions 230 are provided on the radially opposite sides of the connector 220, and multiple snap-fit ​​grooves 111 are provided on the radially opposite sides of the inner wall of the roller brush 100; or, multiple elastic snap-fit ​​portions 230 are provided on the radially opposite sides of the inner wall of the roller brush 100, and multiple snap-fit ​​grooves 111 are provided on the radially opposite sides of the connector 220, so that the multiple elastic snap-fit ​​portions 230 and the multiple snap-fit ​​grooves 111 can be snap-fitted in a one-to-one correspondence.

[0052] By engaging multiple elastic snap-fit ​​parts 230 with multiple snap-fit ​​grooves 111 in a one-to-one correspondence, when one of the elastic snap-fit ​​parts 230 and the snap-fit ​​groove 111 fails to engage, the remaining elastic snap-fit ​​parts 230 and the snap-fit ​​grooves 111 can still maintain engagement, thereby improving the stability of the engagement connection between the roller brush 100 and the handle 200, and more effectively preventing relative shaking between the roller brush 100 and the handle 200. The roller brush 100 is fixed more stably and reliably, so that the roller brush assembly 1 can clean the surface to be cleaned.

[0053] Furthermore, with multiple elastic snap-fit ​​portions 230 located on opposite radial sides of the connector 220, the snap-fit ​​points of the roller brush 100 and the handle 200 can be distributed more evenly, further improving the connection stability of the roller brush 100 and the handle 200.

[0054] In some specific embodiments of this utility model, such as Figure 4 As shown, the roller brush assembly 1 also includes a reset snap ring 300.

[0055] The reset spring 300 is disposed in the connector 220 or the roller brush 100. The reset spring 300 extends circumferentially along the connector 220 or the roller brush 100 and is connected to the elastic snap-fit ​​portion 230 to provide the elastic snap-fit ​​portion 230 to reset towards the snap-fit ​​groove 111.

[0056] In other words, the reset spring 300 can be located inside the connector 220, or the reset spring 300 can be located inside the roller brush 100. For example, when the elastic locking part 230 is located in the connector 220, the reset spring 300 can be located inside the connector 220. When the elastic locking part 230 is located in the roller brush 100, the reset spring 300 can be located inside the roller brush 100. This ensures that the reset spring 300 can abut against the elastic locking part 230.

[0057] For example, when the reset spring 300 is located inside the connector 220 and the connector 220 is assembled with the roller brush 100, the roller brush 100 can be sleeved on the outside of the connector 220. At this time, the elastic locking part 230 can abut against the inner wall of the roller brush 100. The inner wall of the roller brush 100 can squeeze the elastic locking part 230 in the radial direction, so that the elastic locking part 230 undergoes elastic deformation in the radial direction away from the roller brush 100 (i.e., the elastic locking part 230 deforms inward). The elastic locking part 230 will squeeze the reset spring 300, so that the reset spring 300 can generate an elastic force to drive the elastic locking part 230 to reset. Furthermore, when the elastic snap-fit ​​part 230 extends into the snap-fit ​​groove 111, the inner wall of the roller brush 100 no longer presses the elastic snap-fit ​​part 230. The reset snap spring 300, which is in a compressed state, can drive the elastic snap-fit ​​part 230 to return to its original position in the radial direction towards the snap-fit ​​groove 111, so that the elastic snap-fit ​​part 230 can snap into the snap-fit ​​groove 111. Moreover, the reset snap spring 300 can always provide an outward elastic force in the radial direction to the elastic snap-fit ​​part 230, so that the elastic snap-fit ​​part 230 can be stably snapped into the snap-fit ​​groove 111, thereby ensuring a stable connection between the connector 220 and the roller brush 100.

[0058] Furthermore, such as Figure 7 and Figure 8 As shown, the connector 220 is provided with an elastic snap-fit ​​part 230, and a first limiting rib 221 is provided inside the connector 220. A second limiting rib 231 is provided on the side of the elastic snap-fit ​​part 230 that is opposite to the snap-fit ​​groove 111. Along the axial direction of the connector 220, the reset snap spring 300 is clamped between the first limiting rib 221 and the second limiting rib 231.

[0059] By placing the reset spring 300 between the first limiting rib 221 and the second limiting rib 231, the first limiting rib 221 and the second limiting rib 231 can limit the elastic locking part 230 along the axial direction of the connector 220, thereby preventing the reset spring 300 from shifting axially. This allows the reset spring 300 to provide a more stable outward elastic reset force to the elastic locking part 230 in the radial direction, so that the elastic locking part 230 can be stably locked in the locking groove 111.

[0060] In some specific embodiments of this utility model, such as Figure 8 As shown, the elastic snap-fit ​​portion 230 includes an elastic arm 232 and a snap-fit ​​protrusion 233.

[0061] The connector 220 or the roller brush 100 is provided with a clearance hole 223. The elastic arm 232 is provided in the clearance hole 223, and one end of the elastic arm 232 is connected to the inner wall of the clearance hole 223. The snap-fit ​​protrusion 233 is adjacent to the other end of the elastic arm 232 and protrudes from the side of the elastic arm 232 facing the snap-fit ​​groove 111. The snap-fit ​​protrusion 233 snaps into the snap-fit ​​groove 111.

[0062] For example, the snap-fit ​​protrusion 233 may include, but is not limited to, elastic snap-fit ​​components such as elastic metal sheets and spring plungers.

[0063] When the connector 220 is provided with a clearance hole 223, the clearance hole 223 can penetrate radially through the side wall of the connector 220, and the elastic locking part 230 is provided inside the clearance hole 223. In this way, the elastic arm 232 can have sufficient space within the clearance hole 223 to undergo elastic deformation, thereby preventing the elastic locking part 230 from interfering with the rest of the connector 220 during deformation. Alternatively, when the roller brush 100 is provided with a clearance hole 223, the clearance hole 223 can penetrate radially through the side wall of the inner cylinder 110, and the elastic locking part 230 is provided inside the clearance hole 223. In this way, the elastic arm 232 can have sufficient space within the clearance hole 223 to undergo elastic deformation, thereby preventing the elastic locking part 230 from interfering with the rest of the roller brush 100 during deformation.

[0064] By placing the elastic snap-fit ​​part 230 in the clearance hole 223, the elastic snap-fit ​​part 230 and the snap-fit ​​groove 111 can switch between snap-fit ​​and disengagement states, making it easier to assemble and disassemble the roller brush 100 and the handle 200.

[0065] Furthermore, such as Figure 7 As shown, the side of the snap-fit ​​protrusion 233 facing away from the elastic arm 232 has a first guide surface 234 and a second guide surface 235. The first guide surface 234 and the second guide surface 235 are arranged opposite to each other, and the first guide surface 234 is adjacent to the other end of the elastic arm 232.

[0066] Among them, along one end of the elastic arm 232 toward the other end, the first guide surface 234 extends obliquely toward the elastic arm 232, and the second guide surface 235 extends obliquely away from the elastic arm 232.

[0067] In other words, in the axial direction of the connector 220 away from the handle 210, the first guide surface 234 extends obliquely toward the elastic arm 232, and the second guide surface 235 extends obliquely away from the elastic arm 232. That is, the snap-fit ​​protrusion 233 can be constructed as a wedge.

[0068] Thus, when the connector 220 is assembled with the roller brush 100, the user can apply an external force along the axial direction of the roller brush 100 to bring the roller brush 100 and the connector 220 closer to each other. At this time, the first guide surface 234 contacts the inner wall of the inner cylinder 110, and the inner wall of the inner cylinder 110 can press the snap-fit ​​protrusion 233 along the first guide surface 234 so that the snap-fit ​​protrusion 233 can slide along the inner wall of the inner cylinder 110 into the snap-fit ​​groove 111.

[0069] When it is necessary to disassemble the connector 220 from the roller brush 100, the user can apply an external force along the axial direction of the roller brush 100 to separate the roller brush 100 and the connector 220. At this time, the side wall of the snap-fit ​​groove 111 will squeeze the second guide surface 235, so that the elastic snap-fit ​​part 230 deforms inward along the radial direction of the connector 220, thereby allowing the snap-fit ​​protrusion 233 to disengage from the snap-fit ​​groove 111, so as to realize the disassembly of the connector 220 from the inner cylinder 110. That is, the second guide surface 235 can guide the disassembly of the connector 220 and the roller brush 100, which helps to simplify the disassembly steps of the connector 220 and the roller brush 100.

[0070] In some specific embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the inner wall of the roller brush 100 and the connector 220 are respectively provided with a positioning groove 112 and a positioning protrusion 222 that cooperate with each other, and the positioning protrusion 222 is positioned and fitted in the positioning groove 112.

[0071] For example, a positioning groove 112 can be provided on the inner wall of the roller brush 100, and a positioning protrusion 222 can be provided on the outer wall of the connector 220; alternatively, a positioning protrusion 222 can be provided on the inner wall of the roller brush 100, and a positioning groove 112 can be provided on the outer wall of the connector 220. By cooperating with the positioning protrusion 222 and the positioning groove 112, the assembly between the connector 220 and the roller brush 100 can be pre-positioned, which helps improve the assembly accuracy between the connector 220 and the roller brush 100 and simplifies the assembly steps, thereby improving the assembly efficiency between the connector 220 and the roller brush 100.

[0072] Furthermore, the positioning groove 112 and the snap-fit ​​groove 111 can be circumferentially spaced on the inner wall of the roller brush 100, and the positioning protrusion 222 and the elastic snap-fit ​​portion 230 can be circumferentially spaced on the connector 220; or, the positioning protrusion 222 and the elastic snap-fit ​​portion 230 can be circumferentially spaced on the inner wall of the roller brush 100, and the positioning groove 112 and the snap-fit ​​groove 111 can be circumferentially spaced on the connector 220; or, the positioning protrusion 222 and the snap-fit ​​groove 111 can be circumferentially spaced on the inner wall of the roller brush 100, and the positioning groove 112 and the elastic snap-fit ​​portion 230 can be circumferentially spaced on the connector 220; or, the positioning groove 112 and the elastic snap-fit ​​portion 230 can be circumferentially spaced on the inner wall of the roller brush 100, and the positioning protrusion 222 and the snap-fit ​​groove 111 can be circumferentially spaced on the connector 220. This avoids positional interference between adjacent structures, facilitating the assembly between the connector 220 and the roller brush 100.

[0073] Furthermore, such as Figures 6-8 As shown, there are multiple positioning grooves 112, which are arranged at intervals along the circumference of the roller brush 100 or the connector 220. There are multiple positioning protrusions 222, which are matched one-to-one with the multiple positioning grooves 112.

[0074] In this configuration, multiple positioning protrusions 222 are fitted one-to-one into multiple positioning grooves 112, which can further improve the assembly accuracy between the connector 220 and the roller brush 100. Furthermore, the positioning grooves 112 can be used to limit the positioning protrusions 222 along the circumference of the connector 220, which can more effectively prevent relative shaking between the connector 220 and the roller brush 100, and further improve the stability of the connection between the connector 220 and the roller brush 100.

[0075] In some specific embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the width of the positioning groove 112 extending circumferentially along the roller brush 100 increases as it approaches the positioning protrusion 222 along the axial direction of the roller brush assembly 1. Conversely, the width of the positioning protrusion 222 extending circumferentially along the roller brush 100 decreases as it approaches the positioning groove 112 along the axial direction of the roller brush assembly 1.

[0076] For example, the positioning groove 112 can be provided on the inner side wall of the roller brush 100, and the positioning protrusion 222 can be provided on the outer side wall of the connector 220. Along the axial direction of the roller brush assembly 1, the width of the end of the positioning groove 112 near the handle 200 can be larger, and the width of the end of the positioning protrusion 222 away from the handle 200 can be smaller. When assembling the connector 220 with the roller brush 100, the narrower end of the positioning protrusion 222 will first extend into the wider end of the positioning groove 112. This makes it easier to insert the positioning protrusion 222 into the positioning groove 112, and the assembly error tolerance of the positioning protrusion 222 and the positioning groove 112 is higher. In addition, during the assembly process, the side wall of the positioning groove 112 can guide the positioning protrusion 222 during assembly, making the assembly between the connector 220 and the roller brush 100 simpler and improving assembly efficiency.

[0077] Alternatively, the positioning protrusion 222 can be located on the inner wall of the roller brush 100, and the positioning groove 112 can be located on the outer wall of the connector 220. Along the axial direction of the roller brush assembly 1, the width of the end of the positioning groove 112 away from the handle 200 can be larger, and the width of the end of the positioning protrusion 222 near the handle 200 can be smaller. When assembling the connector 220 with the roller brush 100, the narrower end of the positioning protrusion 222 will first extend into the wider end of the positioning groove 112. This facilitates the insertion of the positioning protrusion 222 into the positioning groove 112, resulting in a higher assembly tolerance for the positioning protrusion 222 and the positioning groove 112. Furthermore, during the assembly process, the sidewall of the positioning groove 112 can guide the positioning protrusion 222 during assembly, making the assembly between the connector 220 and the roller brush 100 simpler and improving assembly efficiency.

[0078] In some specific embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the roller brush assembly 1 also includes a pivot 400.

[0079] The pivot 400 is disposed within the connector 220, the connector 220 is rotatably connected to one side of the pivot 400, and the handle 210 is rotatably connected to the other side of the pivot 400.

[0080] By rotatably connecting the connector 220 to one side of the pivot 400, the connector 220 can rotate synchronously with the roller brush 100 to avoid interference of the pivot 400 with the rotation of the roller brush 100, so as to facilitate cleaning of the surface to be cleaned by rotating the roller brush 100.

[0081] Furthermore, the rotation axis of the connector 220 coincides with the central axis of the roller brush 100, and the rotation axis of the handle 210 is perpendicular to the rotation axis of the connector 220. This configuration allows the user to drive the handle 210 to rotate away from the roller brush 100, thereby increasing the disassembly space of the handle and facilitating the removal of the roller brush assembly 1 from the cleaning device 2.

[0082] In some specific embodiments of this utility model, such as Figure 4 and Figure 5 As shown, along the radial direction of the connector 220, the pivot 400 has multiple rotating shafts 410 or multiple shaft holes 211 on opposite sides. The central axis of the rotating shafts 410 or shaft holes 211 is perpendicular to the central axis of the connector 220. The handle 210 is constructed with multiple shaft holes 211 or multiple rotating shafts 410, and the multiple rotating shafts 410 are rotatably fitted into the multiple shaft holes 211 in a one-to-one correspondence.

[0083] For example, multiple pivots 410 may be provided on opposite sides of the pivot 400 along the radial direction of the connector 220, and multiple shaft holes 211 may be constructed in the handle 210; or, multiple shaft holes 211 may be provided on opposite sides of the pivot 400 along the radial direction of the connector 220, and multiple pivots 410 may be constructed in the handle 210.

[0084] In this way, the handle 210 can rotate relative to the pivot 400 about the central axis of the rotating shaft 410, thereby separating the handle 210 from the device body 10 of the cleaning device 2, so that the user can operate the handle 210 to separate the roller brush assembly 1 from the device body 10.

[0085] Furthermore, when the handle 210 rotates around the pivot 410, the angle at which the handle 210 rotates away from the roller brush 100 can be 10° to 90°. That is, the right angle between the handle 210 and the roller brush 100 can be rotated to form an obtuse angle. For example, the angle at which the handle 210 rotates away from the roller brush 100 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°. This ensures that there is a large operating space between the handle 210 and the device body 10, making it easier for the user to disassemble the roller brush assembly 1 by operating the handle 210.

[0086] The cleaning device 2 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0087] like Figure 1 and Figure 2 As shown, the cleaning device 2 includes a device body 10 and a roller brush assembly 1 according to the above embodiment of the present invention. The roller brush assembly 1 is detachably connected to the device body 10.

[0088] For example, cleaning equipment 2 can be a vacuum cleaner or a mite remover, but is not limited to these.

[0089] According to the cleaning device 2 of the present invention, by utilizing the roller brush assembly 1 of the above embodiment of the present invention, the handle 200 and the roller brush 100 of the roller brush assembly 1 are connected by the elastic snap-fit ​​part 230 and the snap-fit ​​groove 111. This not only enables the detachable connection between the handle 200 and the roller brush 100, but also ensures the connection stability between the handle 200 and the roller brush 100. It is convenient to assemble and disassemble and is more stable and reliable in use.

[0090] Other configurations and operations of the roller brush assembly 1 and cleaning device 2 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
