For example, a component or device comprising one or more parts is not limited to the one or more parts listed, but may optionally include one or more parts that are not listed but are inherent to the illustrated product, or one or more parts that should be present based on the described functionality.

[0036] Please refer to FIG. 1 , which shows a garbage collection device 20 of a cleaning robot 100 according to an embodiment of the present application.

[0037] Referring to FIG. 2 , the garbage collection device 20 includes a body 21 , a rotating member 22 , and a driving assembly 23 .

[0038] 2 , the body 21 has a cavity 21 a for accommodating garbage. The walls of the body 21 that enclose the cavity 21 a include a first side wall 211 and two second side walls 212 .

[0039] Referring to Figure 2 , the first sidewall 211 of the main body 21 is configured with an opening 213 extending through the cavity 21a to allow garbage to enter the cavity 21a through the opening 213. When the cleaning robot 100 floats on the water surface M (see Figure 4 ), the opening 213 of the main body 21 is partially underwater and partially above water, allowing surface garbage to enter the garbage collection device 20 through the opening 213. The first sidewall 211 is located on the side of the cleaning robot 100 that is traveling. The opening 213 is provided on the first sidewall 211 to facilitate the collection of garbage by the cleaning robot 100 as it moves forward.

[0040] 3 and 4 , the first sidewall 211 further includes a first sub-wall 211a and a second sub-wall 211b. The first sub-wall 211a and the second sub-wall 211b are located at opposite ends of the opening 213 along the height direction Z of the body 21. The two second sidewalls 212 are located on either side of the first sidewall 211 and are connected to the first sidewall 211.

[0041] Please refer to Figures 3 and 4. The rotating member 22 is located in the cavity 21a of the main body 21 and is arranged adjacent to the opening 213. The opposite ends of the rotating member 22 are rotatably connected to the two second side walls 212. When the cleaning robot 100 floats on the water surface M (please refer to Figure 4), the bottom of the rotating member 22 is located underwater, and the top of the rotating member 22 is located above the water, so that the garbage on the water surface can be brought into the main body 21 during the rolling process. The rotating member 22 is used to move the garbage on the water surface M during the rotation process, and move the garbage on the water surface M into the cavity 21a of the main body 21. Among them, the height direction Z direction is the direction from the bottom to the top.

[0042] Optionally, the rotating member 22 includes but is not limited to a roller brush, etc.

[0043] The driving assembly 23 is provided on the body 21 and is in transmission connection with the rotating member 22, and is used to drive the rotating member 22 to rotate. The driving assembly 23 includes but is not limited to an active drive or a gear transmission structure.

[0044] The present application provides a garbage collection device 20 and a cleaning robot 100. The body 21 is designed to have a cavity 21a for accommodating garbage. The wall surface of the body 21 that encloses the cavity 21a includes a first side wall 211 and two second side walls 212. The first side wall 211 is located on the traveling side of the cleaning robot 100. The first side wall 211 of the body 21 is configured with an opening 213 that passes through the cavity 21a to allow garbage to enter the cavity 21a from the opening 213. The first side wall 211 also includes a first sub-wall 211a and a second sub-wall 211b. The first sub-wall 211a and the second sub-wall 211b are respectively located at both ends of the opening 213 along the height direction Z of the body 21; the two second side walls 212 are located at the two ends of the opening 213. 12 is located on both sides of the first side wall 211 and is respectively connected to the first side wall 211; the rotating member 22 is located in the cavity 21a and is arranged adjacent to the opening 213. The opposite ends of the rotating member 22 are respectively rotatably connected to the two second side walls 212, and the rotating member 22 is used to move garbage on the water surface; the driving component 23 is provided on the main body 21 and is transmission-connected to the rotating member 22, and is used to drive the rotating member 22 to rotate. By providing an opening 213 on the moving side of the main body 21 and providing the rotating member 22 in the main body 21, the driving component 23 drives the rotating member 22 to rotate. The rotating member 22 is used to move garbage on the water surface during the rotation process, and move the garbage on the water surface into the cavity 21a of the main body 21, thereby effectively collecting garbage on the water surface.

[0045] Optionally, referring to Figures 3 and 4 , the walls of the body 21 that enclose the cavity 21a further include a third sidewall 214 and a bottom wall 215. The third sidewall 214 is disposed opposite the first sidewall 211 and connected between the two second sidewalls 212. One side of the first sidewall 211, one side of the third sidewall 214, and one side of the pair of second sidewalls 212 are connected to the periphery of the bottom wall 215.

[0046] Optionally, referring to Figure 4 , the space within the cavity 21a corresponding to the first sub-wall 211a in the height direction Z of the main body 21 constitutes the waste collection chamber 21b. In other words, the first sub-wall 211a, portions of the two second side walls 212, a portion of the third side wall 214, and the bottom wall 215 enclose and form the waste collection chamber 21b. The height of the first sub-wall 211a is equal to the depth of the waste collection chamber 21b. The formation of the waste collection chamber 21b or the installation of the first sub-wall 211a allows waste to be collected within the waste collection chamber 21b, and the first sub-wall 211a prevents waste from overflowing from the chamber 21b.

[0047] Referring to Figure 4 , the highest point of the rotating member 22 along the height Z direction of the main body 21 is higher than the edge 211c of the second sub-wall 211b (i.e., the lower edge of the second sub-wall 211b) that encloses the opening 213. In other words, the second sub-wall 211b blocks the front side of the top end of the rotating member 22 to prevent garbage in the inner cavity from being dislodged during the rotation of the rotating member 22.

[0048] Referring to Figure 4 , the lowest point of the rotating member 22 along the height direction Z of the main body 21 is higher than the edge 211d of the first sub-wall 211a (i.e., the upper edge of the first sub-wall 211a) that encloses the opening 213. In other words, the rotating member 22 is spaced apart from the edge 211d of the first sub-wall 211a (i.e., the upper edge of the first sub-wall 211a) that encloses the opening 213, forming a garbage collection channel. This allows garbage to be carried into the garbage collection device 20 by the rotating rotating member 22 through the garbage collection channel.

[0049] Referring to Figure 2 , the drive assembly 23 includes a rotating gear 231. The rotating gear 231 is disposed outside the two second side walls 212 of the body 21 and is coaxially connected to the rotating member 22. The rotating gear 231 is configured to rotate the rotating member 22. Optionally, the rotating gear 231 is configured to rotate the rotating member 22 under the action of the driving device of the cleaning robot 100, thereby collecting surface debris into the body 21 through the opening 213.

[0050] Optionally, the rotating gears 231 form a group, that is, there are two rotating gears 231 , and the two rotating gears 231 are respectively located on both sides of the cleaning robot 100 along the width direction X. The two rotating gears 231 are respectively coaxially connected to the two ends of the rotating member 22 .

[0051] Optionally, referring to FIG2 , the drive assembly 23 further includes at least one transmission gear 232. The transmission gear 232 is disposed on the outer sides of the two second side walls 212 of the body 21 and is meshed with the rotating gear 231. The transmission gear 232 is configured to be transmission-connected to the drive device 24 of the cleaning robot 100 so that the drive device 24 of the cleaning robot 100 drives the rotating member 22 in the body 21 to roll via the transmission gear 232. The axis of the transmission gear 232 is located between the axis of the rotating gear 231 and the bottom wall 215 of the garbage collection device 20. The axis of the transmission gear 232 is located between the axis of the rotating gear 231 and the bottom wall 215 of the garbage collection device 20.

[0052] Optionally, the transmission gears 232 form a group, that is, there are two transmission gears 232 , and the two transmission gears 232 are respectively located on both sides of the cleaning robot 100 along the width direction X.

[0053] When the cleaning robot 100 is cleaning a water surface, the rotating member 22 has a shallow draft due to its relatively top position. The main structure of the drive unit 24 has a deeper draft. Therefore, the axis of the transmission gear 232 is located between the axis of the rotating gear 231 and the bottom wall 215 of the garbage collection device 20, facilitating transmission connection between the transmission gear 232 and the drive unit 24.

[0054] Please refer to Figure 2. The outer sides of the two second side walls 212 of the body 21 are respectively provided with drive receiving grooves 21d. The drive receiving grooves 21d are used to accommodate at least part of the drive assembly 23. Furthermore, the drive receiving grooves 21d are used to accommodate a rotating gear 231 and at least one transmission gear 232. Since the garbage collection device 20 can be installed on the body 10 of the cleaning robot 100 from the height direction Z downward, by arranging the rotating gear 231 and at least one transmission gear 232 in the drive receiving grooves 21d, it is prevented that the rotating gear 231 and at least one transmission gear 232 hinder the installation of the garbage collection device 20, and it is also beneficial for the transmission gear 232 to be meshed and connected with the second gear in the subsequent drive device 24, thereby realizing a transmission connection between the drive assembly 23 and the drive device 24.

[0055] Furthermore, referring to Figure 4 , the walls of the body 21 that enclose the cavity 21a also include a bottom wall 215. One side of the first sidewall 211, one side of the third sidewall 214, and one side of the pair of second sidewalls 212 are all connected to the periphery of the bottom wall 215. The other side of the first sidewall 211, the other side of the third sidewall 214, and the other side of the pair of second sidewalls 212 surround and form a top opening 216. The bottom wall 215 and the top opening 216 are located opposite each other. The height direction Z is the direction from the bottom to the top.

[0056] Referring to FIG. 4 , in the Y direction of travel of the cleaning robot 100, the top opening 216 of the waste collection device 20 is larger than the bottom wall 215 of the waste collection device 20. The first sidewall 211 further includes a curved surface 217 located between the first sub-wall 211a and the second sub-wall 211b. The opening 213 is located on the curved surface 217.

[0057] In this embodiment, the top opening 216 of the waste collection device 20 is designed to be larger than the bottom wall 215 of the waste collection device 20, resulting in a structure with a longer top (in the Y direction of travel) and a shorter bottom. When the rotating member 22 is located at the top, the longer top provides space for the rotating member 22. Because the rotating member 22 occupies a position slightly forward of the top of the waste collection device 20, the waste collection device 20 still has a relatively large space even after the rotating member 22 is installed. The orthographic projection of the rotating member 22 in the Z direction is located outside the area where the waste collection device 20 is located. Therefore, the rotating member 22 can cause the water entering the opening 213 to ripple, thereby drawing surface debris into the waste collection device 20. Furthermore, because the first sidewall 211 forms a curved surface 217 and the opening 213 is located on the curved surface 217, this embodiment can create a larger opening 213 compared to a surface parallel to the third sidewall 214, thereby more effectively collecting surface debris. The top opening 216 is large, the bottom wall 215 is small, and the first side wall 211 forms an arc surface 217. The connecting shaft between the two first traveling wheels of the cleaning robot 100 (the first traveling wheels will be described in detail later) can be arranged below the arc surface 217, so that the shaft of the first traveling wheel and the garbage collection device 20 are compactly arranged, so that the size of the cleaning robot 100 in the traveling direction Y direction is smaller, and the transmission ratio between the first traveling wheel and the transmission gear 232 is increased.

[0058] Optionally, referring to FIG5 , the third sidewall 214, the bottom wall 215, or at least one of the two second sidewalls 212 of the waste collection device 20 may be provided with a hollow portion 218 and a filter 219 covering the hollow portion 218. The filter 219 is used to filter water within the waste collection device 20. Optionally, both the bottom wall 215 and the third sidewall 214 may be provided with a hollow portion 218 and a filter 219 covering the hollow portion 218.

[0059] Optionally, please refer to Figure 5, the bottom wall 215 of the garbage collection device 20 is provided with a filter 219 to facilitate the water in the garbage collection device 20 to leak out through the filter 219 of the bottom wall 215, thereby reducing the water in the garbage collection device 20, allowing the garbage collection device 20 to collect more garbage, and also reducing the weight of the garbage collection device 20, which is conducive to the cleaning robot 100 floating on the water surface.

[0060] Optionally, as shown in FIG5 , a filter screen 219 is provided on the third side wall 214 of the garbage collection device 20 to facilitate the leakage of water within the garbage collection device 20 through the filter screen 219 on the bottom wall 215. The water filtered out of the filter screen 219 on the third side wall 214 of the garbage collection device 20 flows toward the rear end of the cleaning robot 100, forming a water flow from the front to the rear end. The reaction force formed by the water flow resistance can help propel the cleaning robot 100 forward.

[0061] Optionally, a filter screen 219 is provided on the second side wall 212 of the garbage collection device 20 to facilitate the leakage of water in the garbage collection device 20 through the filter screen 219 on the side wall. During the forward movement of the cleaning robot 100, garbage may be carried by the water flow and block the filter screens 219 on the third side wall 214 and the bottom wall 215. By providing the filter screen 219 on the second side wall 212 of the garbage collection device 20, water can still leak out even when the filter screen 219 on the third side wall 214 of the garbage collection device 20 is blocked, thereby avoiding the situation where the water in the garbage collection device 20 cannot be filtered out due to the filter screen 219 on the third side wall 214 and the bottom wall 215 being blocked.

[0062] Optionally, referring to Figures 4 and 6 , the third sidewall 214 of the waste collection device 20 further includes a sensing member 30, which includes, but is not limited to, a magnet. The sensing member 30 is configured to be positioned adjacent to a sensor 120 in the sealed housing portion 111 of the cleaning robot 100 when the waste collection device 20 is mounted on the storage housing portion 112 of the cleaning robot 100. The sensor 120 is configured to output a signal indicating a cleaning mode upon sensing a signal from the sensing member 30.

[0063] 4 and 6 , the sensor 120 includes but is not limited to a Hall sensor 120 a. The Hall sensor 120 a is configured to output a signal indicating successful installation and / or a signal indicating a water surface cleaning mode when the garbage collection device 20 is installed in the storage housing 112 of the cleaning robot 100 .

[0064] Specifically, the garbage collection device 20 is provided in the housing portion 112 of the cleaning robot 100. The magnet (sensing element 30) of the garbage collection device 20 is located within the sensing range of the Hall sensor 120a. Optionally, the magnet and the Hall sensor 120a are disposed adjacent to each other. Furthermore, the magnet and the Hall sensor 120a are disposed at least partially opposite each other. In other words, the Hall sensor 120a is used to detect the presence of the magnet, and thereby detect the presence of the garbage collection device 20.

[0065] The controller determines that the garbage collection device 20 is successfully installed based on whether the Hall sensor 120a outputs a signal indicating successful installation. The controller can also automatically identify that the working mode of the cleaning robot 100 is the water surface cleaning mode after the cleaning robot 100 is turned on.

[0066] 7 , the present application provides a cleaning robot 100, comprising a body 10, a garbage collection device 20 as described in any of the above embodiments, and a drive device 24. Optionally, there are two drive devices 24, one located on each side of the cleaning robot 100 along the width direction X.

[0067] 7 , the driving device 24 includes a first traveling wheel 241. The first traveling wheel 241 is annular and serves as a front traveling wheel.

[0068] Please refer to Figure 7. The inner ring of the first traveling wheel 241 has a first annular tooth 241a. The first annular tooth 241a is transmission-connected to the rotating gear 231 of the driving assembly 23. Specifically, the first annular tooth 241a is directly or indirectly meshed with the rotating gear 231. The first annular tooth 241a of the rotating gear 231 is meshed with the side close to the rear end. In this way, the position of the garbage collection device 20 is relatively retracted, leaving space for the front end of the cleaning robot 100. The positive projection of the rotating gear 231 in the width direction X of the cleaning robot 100 is located in the space surrounded by the first annular tooth 241a. The first traveling wheel 241 is configured to drive the rotating gear 231 to rotate in the same direction while rotating, and the rotating member 22 rolls in a linkage manner with the first traveling wheel 241.

[0069] Referring to Figures 8 and 9, the driving device 24 also includes a first gear 242 and a second gear 243. The first gear 242 is arranged in the space surrounded by the first annular teeth 241a and is meshed with the first annular teeth 241a. The second gear 243 is coaxially arranged with the first gear 242. The second gear 243 is configured to be meshed with the gear in the driving assembly 23. Furthermore, the second gear 243 is configured to be meshed with the rotating gear 231 through the transmission gear 232. Of course, the first gear 242 and the second gear 243 are also combined into the same gear. The combined gear is relatively long in the axial direction and is meshed with both the first annular teeth 241a and the transmission gear 232 in the axial direction.

[0070] Since the first gear 242 is disposed in the space surrounded by the first annular teeth 241a and is meshed with the first annular teeth 241a, the first gear 242 rotates in the same direction as the first traveling wheel 241. The second gear 243 is coaxially disposed with the first gear 242, so the second gear 243 rotates in the same direction as the first gear 242. The second gear 243 meshes with the rotating gear 231 through the transmission gear 232. In this way, the rotating gear 231, the rotating member 22, and the first traveling wheel 241 rotate in the same direction, so that the rotating member 22 is driven to rotate during the rotation of the first traveling wheel 241. The rotating member 22 for garbage collection does not require an additional drive structure. In this embodiment, the cleaning robot 100 advances and collects garbage simultaneously.

[0071] 7 to 9 , the driving device 24 further includes a second traveling wheel 244 , a transmission member 245 , and a driving motor 246 . The second traveling wheel 244 is a rear traveling wheel. It should be noted that the structure between the first traveling wheel 241 and the second traveling wheel 244 is not shown in FIG. 8 and FIG. 9 .

[0072] The second traveling wheel 244 is spaced apart from the first traveling wheel 241 along the travel direction Y via a transmission member 245. The transmission member 245 surrounds the outer rings of the first and second traveling wheels 241, 244, causing the first and second traveling wheels 241, 244 to move synchronously. The transmission member 245 includes, but is not limited to, a synchronous belt or a crawler track.

[0073] The driving motor 246 is configured to drive the second traveling wheel 244 to rotate. The second traveling wheel 244 drives the first traveling wheel 241 to rotate synchronously through the transmission member 245.

[0074] In this embodiment, the cleaning robot 100 drives the second traveling wheel 244 to rotate through the driving motor 246, and drives the first traveling wheel 241 to rotate synchronously through the transmission member 245. The first traveling wheel 241 drives the rotating member 22 to rotate through the first gear 242, the second gear 243, and the transmission gear 232, so as to realize the rotation of the rotating member 22 during the rotation of the first traveling wheel 241. The rotating member 22 used for garbage collection does not require an additional driving structure.

[0075] Optionally, referring to Figures 7 to 9, the drive device 24 further includes a drive gear 247, a drive paddle gear 248, and a drive paddle 249. The drive gear 247 is coaxially connected to the drive motor 246. The inner ring of the second traveling wheel 244 has a second annular tooth 244a. The second annular tooth 244a is in transmission connection with the drive gear 247. The drive paddle gear 248 is disposed within the space enclosed by the second annular tooth 244a of the second traveling wheel 244 and meshes with the second annular tooth 244a. The drive paddle gear 248 is coaxially connected to the drive paddle 249. The drive paddle 249 rotates in the same direction as the second traveling wheel 244.

[0076] In this embodiment, the drive motor 246 drives the drive paddle 249 to rotate via the second travel wheel 244. In a water surface cleaning scenario, a portion of the drive paddle 249 is disposed underwater. During the rotation of the drive paddle 249, the water is pushed toward the rear end. The reaction force formed by the water resistance forms a driving force to propel the cleaning robot 100 forward.

[0077] In this embodiment, the drive paddle gear 248 is disposed within the space surrounded by the second annular teeth 244a of the second traveling wheel 244 and is meshed with the second annular teeth 244a. The rotating shaft of the drive paddle 249 is located between a group of second annular teeth 244a. In other words, the axis of the drive paddle 249 is located in the area where the second traveling wheel 244 is located. The drive paddle 249 is located in the area between a group of second traveling wheels 244. This increases the compactness of the layout of the drive paddle 249 and the second traveling wheel 244, reduces the size of the cleaning robot 100 in the Y direction of travel, and avoids the problem of poor appearance consistency caused by the drive paddle 249 protruding from the rear end of the second traveling wheel 244. The drive paddle gear 248 is meshed with the second annular teeth 244a to drive the drive paddle 249 to rotate. In this way, the drive device 24 can not only enable the rotating member 22 at the front end of the cleaning robot 100 to roll to achieve garbage collection, but also drive the drive paddle 249 to rotate to drive the cleaning robot 100 forward.

[0078] Optionally, the driving paddle 249, the first traveling wheel 241, the second traveling wheel 244, and the rotating member 22 rotate in the same direction.

[0079] Alternatively, the driving gear 247 can be directly meshed with the second annular gear 244 a. In this way, the driving motor 246 is located between a group of second traveling wheels 244.

[0080] Alternatively, the drive gear 247 can be indirectly meshed with the second annular gear 244a through a multi-stage gear. In this way, the drive motor 246 is arranged between the second traveling wheel 244 and the first traveling wheel 241 in the direction of travel Y. The above design allows the drive motor 246 to drive the second traveling wheel 244 while also being located in front of the second traveling wheel 244. The weight of the drive motor 246 is relatively heavy. Therefore, by arranging the position of the drive motor 246 between the second traveling wheel 244 and the first traveling wheel 241, the overall center of gravity of the cleaning robot 100 is moved forward, the center of gravity of the cleaning robot 100 is stabilized, the stability of the cleaning robot 100 is increased, and the center of gravity is prevented from being shifted backward, which causes the cleaning robot 100 to be unstable during the process of moving forward on the water surface or underwater, and more space is reserved at the rear end of the cleaning robot 100.

[0081] In the height Z direction of the cleaning robot 100, the axis of the driving paddle gear 248 is located between the axis of the second traveling wheel 244 and the top cover of the cleaning robot 100. In other words, the driving paddle 249 is located relatively close to the top of the cleaning robot 100, so that in the water surface cleaning mode, a portion of the driving paddle 249 is located on the water surface, and the driving paddle 249 propels the cleaning robot 100 forward during rotation.

[0082] Optionally, in the height direction Z of the cleaning robot 100, the axis of the rotating member 22 is higher than the axis of the driving paddle gear 248. When on the water surface, the draft of the driving paddle 249 is greater than the draft of the rotating member 22, so that the driving paddle 249 generates a greater force when rolling to drive the cleaning robot 100 forward. The draft of the rotating member 22 is shallow, so that garbage on the water surface can be brought into the water surface garbage collection device 20.

[0083] Optionally, referring to Figure 10, the cleaning robot 100 further includes a buoyancy device 40, which is disposed at the bottom of the body 10. Before the cleaning robot 100 operates in the surface cleaning mode, the buoyancy device 40 is installed at the bottom of the body 10 so that the cleaning robot 100 can float on the water surface.

[0084] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.
