Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1 to 2 As shown, this utility model proposes a cleaning device 10, including a device body 100, a roller brush assembly 200 disposed at the bottom of the device body 100, and a lifting drive mechanism 300 connecting the roller brush assembly 200 and the device body 100. The roller brush assembly 200 can clean the ground (or other surfaces that need cleaning), while the lifting drive mechanism 300 can lift the roller brush assembly 200 to change its height, thereby improving the obstacle-crossing ability of the cleaning device 10 and avoiding secondary pollution to the cleaned ground.

[0038] Moreover, such as Figure 1 and Figure 6As shown, the roller brush assembly 200 may include a roller brush housing 210 hinged to one side of the device body 100, a cleaning roller brush 220 rotatably mounted on the roller brush housing 210, and a roller brush drive member 230 mounted on the roller brush housing 210 and connected to the cleaning roller brush 220. Furthermore, the lifting drive mechanism 300 may include a lifting motor 310 mounted on the device body 100 or the roller brush housing 210, a reel 320 connected to the lifting motor 310, a flexible connector 330 wound on the reel 320, and a guide member 340 mounted on the device body 100 and located above the top of the roller brush housing 210. The flexible connector 330 bypasses the guide member 340 and is connected to the top of the roller brush housing 210.

[0039] When the cleaning equipment 10 is cleaning the floor normally, the cleaning roller brush 220 protruding from the bottom of the main body 100 of the roller brush assembly 200 can clean the floor. When encountering obstacles during the cleaning process, or when the cleaning equipment 10 moves through the already cleaned area during the cleaning process (such as mopping alone), the lifting motor 310 of the lifting drive mechanism 300 can drive the reel 320 to rotate, so that the reel 320 can wind up the flexible connector 330, which can pull up the roller brush housing 210 from the top, lift the roller brush assembly 200, and retract the cleaning roller brush 220 into the bottom of the main body 100 of the equipment. This can reduce the obstruction of the roller brush assembly 200 to the movement, improve the obstacle-crossing ability of the cleaning equipment 10, and also prevent the dirty cleaning roller brush 220 from causing secondary pollution to the already cleaned area when the cleaning equipment 10 moves through the already cleaned area, thereby improving the user experience.

[0040] Specifically, such as Figures 1 to 2 As shown, the main body 100 of the device may include a main unit (not shown in the figure), and a bottom shell 110 located on the bottom side of the main unit. The roller brush assembly 200 and the lifting drive mechanism 300 are disposed on the bottom shell 110. Further, as Figures 3 to 5 As shown, the device's bottom shell 110 may include a bottom shell body 114 located on the bottom side of the main unit, and a bottom shell lower cover 112 covering the bottom of the bottom shell body 114. A mounting cavity 116 is formed between the bottom shell lower cover 112 and the bottom shell body 114, and the roller brush assembly 200 is installed in the mounting cavity 116. The bottom of the bottom shell body 114 is provided with a main mounting groove 1142, and a first auxiliary mounting groove 1144 and a second auxiliary mounting groove 1146 connecting the two sides of the main mounting groove 1142. The main mounting groove 1142 is used to accommodate the roller brush housing 210 of the roller brush assembly 200, the first auxiliary mounting groove 1144 is used to accommodate the roller brush drive component 230 of the roller brush assembly 200, and the second auxiliary mounting groove 1146 is used to accommodate the lifting motor 310, reel 320, and other structures of the lifting drive mechanism 300. The bottom cover 112 can be placed on the bottom of the roller brush assembly 200 and the lifting drive mechanism 300 to limit them.

[0041] Furthermore, a cleaning port 1122 is provided on the lower cover 112 of the bottom shell 110 of the equipment. The top periphery of the cleaning port 1122 has an upwardly protruding cleaning limiting plate 1124, and the bottom side wall of the cleaning port 1122 has a roller brush limiting plate 1126 extending towards the middle of the cleaning port 1122. Moreover, the bottom of the roller brush housing 210 can be located in the cleaning port 1122, and one side of it is hinged to the top of the equipment bottom shell 110. The cleaning roller brush 220 protrudes below the bottom of the cleaning port 1122, and the roller brush limiting plate 1126 is limited to the bottom of the free side of the roller brush housing 210 (referring to the other side corresponding to the hinged side of the roller brush housing 210, that is, the side that can rotate relatively freely). The cleaning limiting plate 1124, which protrudes upward from the top periphery of the cleaning port 1122, can limit the roller brush housing 210 from the periphery, making the roller brush housing 210 and the roller brush assembly 200 more stable and precise when moving up and down. In addition, the roller brush limiting plate 1126, which protrudes from the bottom side of the cleaning port 1122, can limit the automatic side of the roller brush housing 210 that can rotate and move up and down, preventing the roller brush housing 210 from moving down excessively outside the cleaning port 1122.

[0042] In addition, such as Figures 6 to 8 As shown, the roller brush assembly 200 includes a roller brush housing 210, which may include a top roller brush housing 213 and a bottom roller brush housing 214, forming a roller brush cavity. The cleaning roller brush 220 is rotatably disposed in the top roller brush housing 213 and partially protrudes from the bottom opening of the bottom roller brush housing 214. The roller brush drive unit 230 may include a roller brush drive motor 232 disposed at one end of the top roller brush housing 213, and a roller brush transmission structure 234 connected to the roller brush drive motor 232. The roller brush transmission structure 234 is connected to the end of the cleaning roller brush 220 and can drive the cleaning roller brush 220 to rotate via the roller brush drive motor 232.

[0043] Furthermore, a hinge bracket 216 can be provided at each end of one side of the top shell 213 of the roller brush, and two hinge seats 118 are provided on the bottom shell body 114 or the bottom shell cover 112 of the bottom shell 110 of the equipment. The hinge bracket 216 can be rotatably mounted on the two hinge seats 118 in a corresponding manner, so that one side of the roller brush shell 210 can be hinged to the bottom shell 110 of the equipment.

[0044] In addition, such as Figures 6 to 9As shown, the flexible connector 330 of the lifting drive mechanism 300 may include a flexible rope 332 or flexible belt that passes around the guide member 340. One end of the flexible rope 332 or flexible belt is wound on the reel 320, and the other end is connected to the top of the top shell of the roller brush housing 210. The reel 320 can be driven to rotate by the lifting motor 310, so that the reel 320 can wind up or release the flexible rope 332 or flexible belt, thereby lifting or lowering the roller brush housing 210 and the roller brush assembly 200 through the flexible rope 332 or flexible belt.

[0045] Furthermore, the flexible connector 330 may include a first engaging portion 334 and a second engaging portion 336 respectively disposed at both ends of the flexible rope 332 or the flexible strip. The first engaging portion 334 is movably engaged at the top of the roller brush housing 210, and the second engaging portion 336 is movably engaged on the reel 320. The first engaging portion 334 allows one end of the flexible rope 332 or the flexible strip to be detachably engaged at the top of the roller brush housing 210 of the roller brush assembly 200, and the second engaging portion 336 allows the other end of the flexible rope 332 or the flexible strip to be detachably engaged on the reel 320, facilitating the installation, disassembly, replacement, and maintenance of the flexible connector 330.

[0046] Furthermore, the top of the roller brush housing 210 may be provided with a connecting protrusion 212, and the connecting protrusion 212 is provided with a first locking groove 2122. Moreover, the first locking part 334 may include a first locking block provided at one end of the flexible rope 332 or flexible strip, and the first locking block is movably locked in the first locking groove 2122. The first locking block can be locked by the first locking groove 2122 on the connecting protrusion 212, thereby fixing one end of the flexible rope 332 or flexible strip to the top of the roller brush housing 210; in addition, when it is necessary to disassemble the flexible rope 332 or flexible strip, the first locking block can be removed from the first locking groove 2122, so that the flexible rope 332 or flexible strip is separated from the roller brush housing 210.

[0047] Furthermore, the first slot 2122 on the connecting protrusion 212 may include a first inlet slot extending from the outer side to the inner side of the connecting protrusion 212, and a first engaging slot communicating with the first inlet slot, with the outer side of the first inlet slot communicating with the outside. The first locking block can move along the bottom of the first inlet slot and engage at the bottom of the first engaging slot, while the flexible rope 332 or flexible band can be threaded through the top of the first engaging slot. In this embodiment, the first locking block can be configured as a first cylindrical block extending vertically, the flexible rope 332 or flexible band can be connected to the end of the first cylindrical block, and the first cylindrical block can be engaged vertically at the bottom of the first engaging slot.

[0048] Furthermore, the reel 320 may be provided with a second locking groove 322. The second locking portion 336 may include a second locking block located at the other end of the flexible rope 332 or flexible strip, the second locking block being movably locked in the second locking groove 322. Similarly, the second locking block can be locked in place by the second locking groove 322 on the reel 320, thereby fixing the other end of the flexible rope 332 or flexible strip to the reel 320; furthermore, when it is necessary to disassemble the flexible rope 332 or flexible strip, the second locking block can be removed from the second locking groove 322, separating the flexible rope 332 or flexible strip from the reel 320.

[0049] Furthermore, the reel 320 has a main body and two side plates on either side of the main body. A groove is formed between the two side plates for winding and storing the flexible rope 332 or flexible strip. The second slot 322 may include a second inlet slot on one side of the reel 320 side plate and a second engaging slot connected to the inside of the second inlet slot. The second inlet slot communicates with the reel 320 groove and the outside, allowing the flexible rope 332 or flexible strip to pass through and enter the reel 320 groove. The second engaging slot extends laterally into the other side of the reel 320 side plate to engage the second engaging block. In this embodiment, the second engaging block is a laterally extending cylindrical block. The flexible rope 332 or flexible strip can be connected to the circumferential surface of the middle portion of the second cylindrical block, which can be laterally engaged in the second engaging slot.

[0050] Furthermore, the flexible connector 330 can be connected to at least one of the middle and / or two sides of the top of the brush housing 210. That is, the flexible connector 330 can be connected at the middle position of the top of the brush housing 210, where the force is evenly distributed; in addition, the flexible connector 330 can also be connected to one or both sides of the top of the brush housing 210; furthermore, the flexible connector 330 can also be connected simultaneously to the middle position of the top of the brush housing 210 and one or both sides of the top of the brush housing 210. When the flexible connector 330 is connected to multiple positions on the top of the brush housing 210, the flexible connector 330 may include multiple flexible ropes 332 or multiple flexible strips; moreover, the reel 320 may be provided with one or more, so that multiple flexible ropes 332 or multiple flexible strips can be wound or released by one reel 320, or multiple flexible ropes 332 or multiple flexible strips can be wound or released by multiple reels 320 respectively. Furthermore, multiple reels 320 can be driven by the same lifting motor 310, or by multiple lifting motors 310.

[0051] In this embodiment, the flexible connector 330 may include a flexible rope 332 connected to one side of the top of the roller brush housing 210, and a lifting motor 310 and a reel 320 correspondingly disposed on one side of the roller brush housing 210.

[0052] Furthermore, the guide member 340 may include a guide wheel or guide shaft disposed on the equipment body 100, and the flexible connector 330 is wound around the guide wheel or guide shaft. The guide wheel or guide shaft disposed on the bottom shell body 114 of the equipment bottom shell 110 of the equipment body 100 can provide sliding support and guidance for the flexible rope 332 or flexible belt of the flexible connector 330, facilitating the lifting or lowering of the roller brush housing 210 and the roller brush assembly 200.

[0053] In addition, such as Figure 9 As shown, the lifting drive mechanism 300 may include a self-locking frame 350 disposed on the equipment base shell 110 of the equipment body 100. A disc body protrusion 324 protrudes from the periphery of the reel 320, and the disc body protrusion 324 cooperates with the self-locking frame 350. When the lifting motor 310 drives the reel 320 to rotate counterclockwise, the reel 320 winds the flexible connector 330 so that the flexible connector 330 lifts the roller brush assembly 200 to a preset height; when the flexible connector 330 maintains the lifted state of the roller brush assembly 200, the self-locking frame 350 locks with the disc body protrusion 324.

[0054] Furthermore, after the roller brush assembly 200 is lifted by the flexible connector 330, it remains in an elevated state. If the motor torque of the lifting motor 310 is small at this time, the roller brush assembly 200 may fall. When the lifting motor 310 drives the reel 320 to rotate counterclockwise (i.e., forward), the disc protrusion 324 of the reel 320 can pass over the self-locking frame 350, so that the self-locking frame 350 blocks the disc protrusion 324 in the opposite direction to achieve self-locking of the reel 320. When the lifting motor 310 drives the reel 320 to rotate clockwise (i.e., reverse), the disc protrusion 324 of the reel 320 can overcome the blockage of the self-locking frame 350 on the disc protrusion 324, so that the reel 320 reverses to release the flexible connector 330, so that the roller brush assembly 200 moves downward under its own gravity, thus realizing the descent action of the roller brush assembly 200.

[0055] Furthermore, the self-locking frame 350 may include a main frame 352 disposed on the equipment base shell 110 of the equipment body 100, and a self-locking protrusion 354 protruding from one side of the main frame 352, the self-locking protrusion 354 correspondingly cooperating with the reel body protrusion 324. When the reel 320 rotates forward under the drive of the lifting motor 310, the reel body protrusion 324 of the reel 320 can squeeze the self-locking protrusion 354, so that the reel body protrusion 324 can rotate past the self-locking protrusion 354 to wind up the flexible connector 330; after the reel body protrusion 324 passes past the self-locking protrusion 354, it separates from it, and the self-locking protrusion 354 can limit the reel body protrusion 324 from the opposite direction, thereby realizing the self-locking of the reel 320.

[0056] Similarly, when the reel 320 reverses under the drive of the lifting motor 310, the disc body protrusion 324 can squeeze the self-locking protrusion 354, causing the disc body protrusion 324 to rotate in the opposite direction and pass over the self-locking protrusion 354, so that the reel 320 rotates in the opposite direction to release the flexible connector 330.

[0057] In summary, the cleaning device 10 provided by this utility model can raise the roller brush assembly 200 through the lifting drive mechanism 300 when mopping the floor alone, so as to prevent the roller brush from contaminating the already cleaned floor; when crossing obstacles, the roller brush assembly 200 can be raised through the lifting drive mechanism 300 to improve the passability of the device.

[0058] Furthermore, in this embodiment, the cleaning device 10 can be a robotic vacuum cleaner having the aforementioned lifting drive mechanism 300 and roller brush assembly 200. Alternatively, the cleaning device 10 can also be a handheld robotic vacuum cleaner or mop having the aforementioned lifting drive mechanism 300 and roller brush assembly 200, etc.
