[0043] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a cleaning roller 100 for an intelligent cleaning device. The intelligent cleaning device drives the cleaning roller 100 to rotate, thereby sweeping debris from the ground into the intelligent cleaning device. This intelligent cleaning device can be a cleaning robot, a handheld vacuum cleaner, a sweeping robot, etc.

[0044] Combination Figure 3 and Figure 4 As shown, the cleaning roller 100 includes a roller brush 110, a cutting mechanism 120, and a drive device 130.

[0045] The roller brush 110 is rotatable about its own axis. The roller brush 110 is driven to rotate about its own axis by the drive component of the intelligent cleaning device to perform cleaning operations.

[0046] The cutting mechanism 120 includes a first cutting element 121 and a second cutting element 122. The first cutting element 121 is fixedly mounted on the roller brush 110, and the second cutting element 122 is axially movable on the roller brush 110. The second cutting element 122 and the first cutting element 121 move relative to each other to increase and decrease the gap between the second cutting element 122 and the first cutting element 121, thereby cutting hair or filaments and other debris wrapped around the roller brush 110.

[0047] The drive device 130 includes a movable member 131 and a mounting member 133. The movable member 131 is fixedly connected to the second cutting member 122. The movable member 131 is provided with a protrusion 1311. The movable member 131 and the mounting member 133 are rotatably disposed relative to each other. An inclined annular groove 1331 is formed on the outer periphery of the mounting member 133. The protrusion 1311 is movably disposed in the annular groove 1331. The protrusion 1311 moves within the inclined annular groove 1331 to realize the reciprocating movement of the movable member 131 along the axial direction of the roller brush member 110. Thus, when the movable member 131 rotates relative to the mounting member 133, it drives the movable member 131 to reciprocate along the axial direction of the roller brush member 110, thereby driving the second cutting member 122 to move relative to the first cutting member 121.

[0048] The cleaning roller 100 provided in the embodiments of this application is applied to an intelligent cleaning device. When the intelligent cleaning device drives the roller brush 110 to rotate, the movable part 131 and the mounting part 133 rotate relative to each other. At this time, the movable part 131 drives the second cutting part 122 to move relative to the first cutting part 121, so as to increase and decrease the gap between the second cutting part 122 and the first cutting part 121, thereby cutting the hair or filaments and other debris wrapped on the roller brush 110, preventing the hair or filaments from getting tangled on the roller brush 110 and affecting the cleaning effect of the roller brush 110, improving the cleaning effect of the cleaning roller 100, and thus improving the cleaning effect of the intelligent cleaning device.

[0049] like Figure 3 and Figure 7As shown, in some embodiments, the protrusion 1311 is arranged in a ring on the outer peripheral surface of the movable member 131. In this embodiment, the protrusion 1311 is arranged in a ring on the outer peripheral surface of the movable member 131. In this way, when the movable member 131 moves relative to the mounting member 133, the ring-shaped protrusion 1311 engages with the inclined annular groove 1331 on the mounting member 133, which facilitates the movement of the movable member 131 along the axial direction of the roller brush member 110, thereby driving the second cutting member 122 to move relative to the first cutting member 121, so as to cut off the hair or filaments and other debris wrapped around the roller brush member 110.

[0050] For example, the end of the protrusion 1311 is formed with an arc surface to facilitate engagement with the annular groove 1331.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the drive device 130 further includes a guide member 132, and the movable member 131 is movably sleeved or connected to the guide member 132 so that the movable member 131 reciprocates along the axial direction of the roller brush member 110. In this embodiment, by providing the guide member 132, the movable member 131 is movably connected to the guide member 132, which guides the movable member 131 as it reciprocates along the axial direction of the roller brush member 110, improving the stability of the movable member 131 during movement and preventing the movable member 131 from deviating during movement.

[0052] For example, the movable member 131 is sleeved on the guide member 132. Of course, in other embodiments, the movable member 131 can also be movably connected to the guide member 132 via a guide groove, such as a dovetail groove structure that mates with the guide member 132. The guide member 132 can be a guide rail or a guide post.

[0053] like Figure 3 and Figure 8 As shown, in some embodiments, the cleaning roller 100 further includes a limiting member 140, which is fixed to the roller brush 110 and disposed at the end of the guide member 132 away from the mounting member 133, for preventing the movable member 131 from disengaging from the guide member 132. In this embodiment, the limiting member 140 is fixed at the end of the guide member 132 away from the mounting member 133, that is, this end of the guide member 132 is connected to the limiting member 140. The limiting member 140 restricts the movable member 131 from moving out of this end of the guide member 132, thereby improving the reliability of the product.

[0054] like Figure 5 As shown, in some embodiments, the movable member 131 is also provided with a clearance groove 1312, which is disposed relative to the end of the limiting member 140. In this embodiment, the clearance groove 1312 is provided to prevent the movable member 131 from interfering with the limiting member 140 when it moves along the guide member 132.

[0055] In the embodiment of the limiting member 140 described above, a clamping member 150 is provided on the roller brush member 110. The clamping member 150 has a clamping groove 151, and the limiting member 140 is disposed in the clamping groove 151. The clamping member 150 is used to restrict the limiting member 140 from moving axially along the roller brush member 110. In this embodiment, the limiting member 140 is fixed to the roller brush member 110 by the clamping member 150. Specifically, the limiting member 140 is clamped in the clamping groove 151, thus preventing the limiting member 140 from moving axially along the roller brush member 110. Of course, in other embodiments, the limiting member 140 can also be fixed to the roller brush member 110 by screws. Specifically, the limiting member 140 can be fixedly installed on the roller brush member 110 by three screws.

[0056] like Figure 5 and Figure 7 As shown, in some embodiments, two guide members 132 are provided. The movable member 131 includes a first movable part 131a, a connecting part 131b, and a second movable part 131c. The first movable part 131a is fixedly connected to the second cutting member 122, and one end of the first movable part 131a is connected to one end of the connecting part 131b, while the other end of the connecting part 131b is connected to the second movable part 131c. Both the first movable part 131a and the second movable part 131c extend axially along the roller brush member 110. The first movable part 131a is sleeved on one guide member 132, and the second movable part 131c is sleeved on the other guide member 132. A protrusion 1311 is arranged circumferentially along the second movable part 131c.

[0057] In this embodiment, two guide members 132 are provided. A first movable part 131a is sleeved on one guide member 132, and a second movable part 131c is sleeved on the other guide member 132. Thus, when the movable member 131 moves, the first movable part 131a and the second movable part 131c move along the guide member 132 they cooperate with, improving the stability of the movable member 131 during movement. This, in turn, makes the second cutting member 122 more stable when moving along the axial direction of the roller brush member 110. The first movable part 131a is used for a fixed connection with the second cutting member 122 to facilitate the movement of the second cutting member 122.

[0058] For example, two guide members 132 are disposed on the outside of the deceleration mechanism 134.

[0059] In some embodiments, at least one guide member 132 is provided, and the movable member 131 is movably sleeved on the guide member 132. Exemplarily, one guide member 132 is provided, and the movable member 131 is movably sleeved on or connected to one guide member 132 to achieve a guiding and restricting effect on the movable member 131. Of course, three guide members 132 may also be provided, with the movable member 131 sleeved on each of the three guide members 132 respectively.

[0060] like Figure 6 and Figure 8 As shown, in some embodiments, the cleaning roller 100 further includes a support 160, the second cutting member 122 is fixed on the support 160, and the support 160 is fixedly connected to the movable member 131. In this embodiment, through the setting of the support 160, the support 160 is fixedly connected to both the second cutting member 122 and the movable member 131, thereby achieving a fixed connection between the second cutting member 122 and the movable member 131. The setting of the support 160 facilitates the assembly of the second cutting member 122. At the same time, the support 160 extends along the length direction of the second cutting member 122 to fit snugly, preventing the second cutting member 122 from bending during cutting.

[0061] like Figure 8 As shown, in some embodiments, one of the bracket 160 and the second cutting member 122 is provided with a positioning post 161, and the other is provided with a positioning hole 1221. The positioning post 161 is inserted into the positioning hole 1221 to fix the second cutting member 122 to the bracket 160. In this embodiment, the second cutting member 122 is fixed to the bracket 160 by inserting the positioning post 161 into the positioning hole 1221. Exemplarily, a plurality of positioning posts 161 are provided at intervals along the length direction of the bracket 160, and a plurality of positioning holes 1221 are provided correspondingly along the length direction of the second cutting member 122, with one positioning post 161 inserted into one positioning hole 1221. Of course, in other embodiments, the second cutting member 122 can also be fixed to the bracket 160 by screws or by hooks and holes.

[0062] like Figure 4 and Figure 5 As shown, in some embodiments, the first cutting member 121 is provided with a groove 1211, and the positioning post 161 can move within the groove 1211. In this embodiment, the groove 1211 is provided on the first cutting member 121 to prevent the positioning post 161 from interfering with the first cutting member 121 when it moves along the length direction of the bracket 160 (i.e., the axial direction of the roller brush 110).

[0063] like Figure 6 As shown, in some embodiments, one of the movable member 131 and the bracket 160 is provided with a slot 162, and the other is provided with a snap-fit ​​part 1313. The snap-fit ​​part 1313 snaps into the slot 162 to fix the movable member 131 and the bracket 160. In this embodiment, the fixed connection between the movable member 131 and the bracket 160 is achieved by the cooperation of the snap-fit ​​part 1313 and the slot 162, which facilitates assembly. Of course, in other embodiments, the movable member 131 and the bracket 160 can also be fixedly connected by the cooperation of screws and threaded holes.

[0064] like Figure 3 and Figure 4 As shown, in some embodiments, the drive device 130 further includes a reduction mechanism 134, which is fixedly connected to the roller brush 110, and the output shaft 1342 of the reduction mechanism 134 is fixedly connected to the mounting member 133. In this embodiment, when the roller brush 110 rotates, it drives the housing 1341 of the reduction mechanism 134 to rotate, thereby driving the planetary gear set 1343 inside the reduction mechanism 134 to rotate, so that its output shaft 1342 drives the mounting part 133 to rotate. Since the movable part 131 rotates synchronously with the roller brush 110, under the action of the reduction mechanism 134, the rotation speed of the movable part 131 is higher than the rotation speed of the mounting part 133, thereby causing the movable part 131 to rotate relative to the mounting part 133. Since the annular groove 1331 of the mounting part 133 is inclined, it can drive the movable part 131 to move back and forth along the axial direction of the roller brush 110, thereby driving the second cutting part 122 to move relative to the first cutting part 121. The relative movement of the second cutting part 122 and the first cutting part 121 can cut the hair and other debris wrapped on the roller brush 110.

[0065] like Figure 9 As shown, the reduction mechanism 134 includes a housing 1341, a mounting plate 1344, and a planetary gear set 1343. The housing 1341 is fixedly connected to the roller brush 110. The inner wall of the housing 1341 is provided with a toothed groove 13411, which meshes with a gear in the planetary gear set 1343. The planetary gear set 1343 is rotatably mounted on the mounting plate 1344. The output shaft 1342 is fixedly connected to the planetary gear set 1343, so that when the housing 1341 rotates, it drives the internal planetary gear set 1343 to rotate, thereby causing the output shaft 1342 to rotate.

[0066] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the cleaning roller 100 further includes a connector 170 and a mounting shaft 180. One end of the mounting shaft 180 is rotatably connected to the reduction mechanism 134, and the other end of the mounting shaft 180 passes through the roller brush 110 and is fixedly connected to the connector 170. The connector 170 is used to fixally connect to the housing of the intelligent cleaning device. In this embodiment, when the reduction mechanism 134 rotates, both the mounting shaft 180 and the connector 170 remain stationary.

[0067] In some embodiments, the reduction mechanism 134 is further provided with a connecting shaft 1345, one end of the connecting shaft 1345 is fixedly connected to the mounting plate 1344, and the other end of the connecting shaft 1345 is fixedly connected to the mounting shaft 180, so that the mounting shaft 180 can be rotatably connected relative to the housing 1341 and the planetary gear set 1343 of the reduction mechanism 134.

[0068] In some embodiments, a drive shaft 190 is provided at one end of the roller brush 110 away from the connector 170. The drive shaft 190 is connected to the drive component of the intelligent cleaning device. When the drive component is working, it causes the drive shaft 190 to rotate, thereby driving the roller brush 110 to rotate.

[0069] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the roller brush 110 is provided with a receiving cavity 111, and the driving device 130 is disposed in the receiving cavity 111. In this embodiment, the movable member 131, the guide member 132, and the deceleration mechanism 134 are all disposed in the receiving cavity 111, and a portion of the second cutting member 122 protrudes circumferentially from the receiving cavity 111.

[0070] It should be noted that in any of the above embodiments, both the first cutting member 121 and the second cutting member 122 include cutting teeth, and the cutting teeth of the first cutting member 121 and the cutting teeth of the second cutting member 122 are staggered.

[0071] Embodiments of this application also provide an intelligent cleaning device (not shown in the figures), including a housing and a cleaning roller 100 as described in any of the above embodiments, the cleaning roller 100 being rotatably mounted on the housing.
