Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning device and a cleaning robot. Background Art

[0002] The ends of a cleaning robot's cleaning roller are typically mounted on the inner wall of a roller groove. A motor that drives the cleaning roller is connected to one end of the cleaning roller, and the motor drives the cleaning roller to rotate, thereby cleaning the floor. Current cleaning rollers are prone to hair entanglement, requiring users to frequently disassemble and handle the cleaning roller. To address this issue, one end of the cleaning roller is typically mounted on the inner wall of the roller groove, leaving the other end free. This can address the hair entanglement issue, but since one end of the cleaning roller is suspended in the air, the roller's stability during rotation is poor. Utility Model Content

[0058] As Figures 1 to 4 shown, some embodiments of the present application provide a cleaning device, which is mainly applied to a cleaning robot to improve the convenience of installing or disassembling the cleaning roller 300 and improve the efficiency of disassembling or installing the cleaning roller 300.

[0059] The cleaning device includes a housing 100, a cleaning roller 300, and a driving mechanism 800.

[0060] Among them, the housing 100 defines a roller groove 110. A holding member 900 is fixedly provided in the roller groove 110, and a connecting ring 200 is sleeved on the holding member 900 and can rotate relative to the holding member 900. The holding member 900 is fixedly connected to the housing 100 to provide a supporting effect on the connecting ring 200 through the holding member 900 to ensure the stability of the connecting ring 200 during the rotation on the holding member 900.

[0061] The cleaning roller 300 is rotatably arranged in the roller groove 110, and there is a gap between the cleaning roller 300 and the groove wall of the roller groove 110 to ensure the smoothness of the cleaning roller 300 during rotation.

[0062] In addition, the cleaning roller 300 has a connecting end 310 and a free end 320. The connecting end 310 is fixedly connected to the connecting ring 200, and the cleaning roller 300 is supported by the holding member 900 to ensure the stability of the cleaning roller 300 on the holding member 900 and the stability of the connection between the cleaning roller 300 and the connecting ring 200. It should be noted that since the connecting ring 200 can rotate relative to the housing 100 and the holding member 900, that is, the connecting end 310 can rotate relative to the housing 100 and the holding member 900, so that the cleaning roller 300 can rotate relative to the housing 100 and the holding member 900.

[0063] Specifically, the driving mechanism 800 drives the cleaning roller 300 to rotate relative to the holding member 900. That is, when the driving mechanism 800 operates, it can drive the cleaning roller 300 to rotate, so as to clean the cleaning surface through the cleaning roller 300.

[0064] The driving mechanism 800 includes a driving motor 810, a transmission device 820, and a driving shaft 830.

[0065] Among them, the output end of the driving motor 810 is in transmission connection with the driving shaft 830 through the transmission device 820. That is, during the rotation of the output shaft of the driving motor 810, power can be transmitted to the driving shaft 830 through the transmission device 820, and the driving shaft 830 can be driven to rotate by the transmission device 820.

[0066] In this embodiment, the drive shaft 830 passes through the holder 900 and is coaxially positioned and inserted into the cleaning roller 300 to drive the cleaning roller 300 to rotate. It can be understood that during the rotation of the drive shaft 830, the cleaning roller 300 can be driven to rotate synchronously. Since the connecting ring 200 is rotatably connected to the holder 900, and the connecting end 310 of the cleaning roller 300 is connected to the connecting ring 200, the cleaning roller 300 is rotatably connected to the holder 900 through the connecting ring 200. That is to say, during the rotation of the cleaning roller 300, it can rotate relative to the holder 900. Under the restriction of the holder 900 and the drive shaft 830, it is ensured that the cleaning roller 300 can stably rotate around its own axis, and the cleaning roller 300 is not easily shaken during rotation, with better stability, thereby ensuring the uniformity and cleaning quality of the cleaning surface during the rotation of the cleaning roller 300.

[0067] As Figure 2 shown, in some embodiments of the present application, the cleaning device further includes a bearing 1000.

[0068] Wherein, the inner ring of the bearing 1000 is fixedly sleeved on the holder 900 to provide support and fixation for the bearing 1000 through the holder 900. In addition, the outer ring of the bearing 1000 is fixed within the connecting ring 200, thereby providing support and fixation for the connecting ring 200. The outer ring of the bearing 1000 can rotate relative to the inner ring of the bearing 1000, that is, the connecting ring 200 can rotate relative to the holder 900. Since the connecting ring 200 is connected to the connecting end 310 of the cleaning roller 300, the cleaning roller 300 can rotate relative to the holder 900.

[0069] As Figure 2 and Figure 5 shown, in some embodiments of the present application, the connecting end 310 is sleeved on the connecting ring 200. At least one first mounting hole 210 is provided on the outer periphery of the connecting ring 200, and at least one first connecting hole 312 is provided on the outer periphery of the connecting end 310, and the first mounting hole 210 and the first connecting hole 312 are correspondingly arranged.

[0070] Wherein, the number of the first mounting holes 210 and the number of the first connecting holes 312 can be one, two or more than two respectively, and can be specifically set according to the actual situation.

[0071] In this embodiment, the number of the first mounting holes 210 is equal to the number of the first connecting holes 312, and one first mounting hole 210 corresponds to one first connecting hole 312.

[0072] It should be noted that in some embodiments, the number of the first mounting holes 210 and the number of the first connecting holes 312 are both multiple. The multiple first mounting holes 210 are arranged at equal intervals along the outer periphery of the connecting ring 200, and the multiple first connecting holes 312 are arranged at equal intervals along the outer periphery of the connecting end 310, and one first mounting hole 210 corresponds to one first connecting hole 312.

[0073] Specifically, the connecting end 310 and the connecting ring 200 are connected by a plurality of fasteners 500. The fasteners 500 sequentially pass through the first connecting holes 312 and the first mounting holes 210 to fixedly connect the connecting end 310 to the connecting ring 200.

[0074] It can be understood that when the fastener 500 passes through the first connecting hole 312 and is connected to the hole wall of the first mounting hole 210, at this time, by adjusting the limiting member 400 to the first position, the cleaning roller 300 is limited by the limiting member 400, so as to prevent the cleaning roller 300 from rotating during the process of the user screwing the fastener 500, thereby ensuring the stability of the user when screwing the fastener 500 and the stability of the force on the cleaning roller 300, and thus effectively improving the installation or disassembly efficiency of the cleaning roller 300.

[0075] As Figure 5 shown, in some embodiments of the present application, at least one positioning boss 220 is provided on the outer periphery of the connecting ring 200. It can be understood that the number of the positioning bosses 220 can be one, two or more than two, and can be specifically set according to the actual situation.

[0076] It should be noted that when the number of the positioning bosses 220 is multiple, the multiple positioning bosses 220 are arranged at intervals along the outer periphery of the connecting ring 200.

[0077] Among them, the positioning boss 220 and the first mounting hole 210 are arranged at intervals to prevent the positioning boss 220 from blocking the first mounting hole 210.

[0078] In addition, at least one notch 313 is provided on the side of the connecting end 310 facing the positioning boss 220. It can be understood that the number of the notches 313 can be one, two or more than two, and can be specifically set according to the actual situation. It should be noted that the notch 313 and the first connecting hole 312 are arranged at intervals to prevent the notch 313 from communicating with the first connecting hole 312 and affecting the stability of the fastener 500 in the first connecting hole 312.

[0079] In this embodiment, the number of the notches 313 is equal to the number of the positioning bosses 220, and one positioning boss 220 is received in one notch 313, and at least a part of the inner wall of the notch 313 abuts against the outer wall of the positioning boss 220, so as to form a limiting structure through the inner wall of the notch 313 and the positioning boss 220, to prevent relative rotation between the connection end 310 and the connection ring 200 when the connection end 310 and the connection ring 200 are installed.

[0080] It should be noted that when the positioning boss 220 is clamped in the notch 313, the first mounting hole 210 corresponds to and communicates with the first connection hole 312, that is, the positioning boss 220 and the notch 313 can provide guiding and anti-fooling functions when the cleaning roller 300 and the connection ring 200 are installed, so as to ensure the accuracy of the installation position between the cleaning roller 300 and the connection ring 200 and improve the installation efficiency.

[0081] As Figure 2 shown, in some embodiments of the present application, the cleaning device further includes a limiting member 400, and the limiting member 400 is movably connected to the housing 100. It should be noted that the connection manner between the limiting member 400 and the housing 100 includes at least one of sliding connection, rotational connection, snap connection, and magnetic attraction connection, which can be specifically set according to actual situations.

[0082] In this embodiment, the limiting member 400 is used to limit the connection end 310 to limit the rotation of the cleaning roller 300, so as to facilitate the fixation of the connection end 310 and the connection ring 200.

[0083] It should be noted that when the cleaning roller 300 is disassembled from or installed in the roller groove 110, the connection end 310 is limited by the limiting member 400. At this time, the user can disassemble or install the cleaning roller 300 from the connection ring 200, and during the disassembly or installation process, the cleaning roller 300 will not rotate, so as to avoid the deviation of the acting force of the user for disassembling the cleaning roller 300 and the force direction of the cleaning roller 300, and ensure that the acting force direction of the user for disassembling or installing the cleaning roller 300 and the force direction of the cleaning roller 300 are on the same straight line, thereby improving the disassembly or installation efficiency.

[0084] As Figure 2 shown, in some embodiments of the present application, a first limiting portion 311 is provided on the outer periphery of the connection end 310, and a second limiting portion 410 is provided on the side of the limiting member 400 facing the cleaning roller 300. The second limiting portion 410 can be connected to the first limiting portion 311 to form a limiting structure, so as to fix the cleaning roller 300 through the limiting structure and prevent the cleaning roller 300 from rotating, thereby ensuring the stability of the cleaning roller 300.

[0085] In this embodiment, when the limiting member 400 moves relative to the housing 100, it has a first position and a second position. It can be understood that during the movement of the limiting member 400, it can switch between the first position and the second position.

[0086] Specifically, in the first position, at least a part of the second limiting portion 410 is connected to the first limiting portion 311 to form a limiting structure for restricting the rotation of the cleaning roller 300. At this time, the user can disassemble or install the cleaning roller 300 from the connecting ring 200. That is, during the disassembly or installation process, the cleaning roller 300 will not rotate, so as to avoid the deviation of the acting force of the user for disassembling the cleaning roller 300 and the force direction of the cleaning roller 300 during the disassembly or installation process, and ensure that the acting force direction of the user for disassembling or installing the cleaning roller 300 and the force direction of the cleaning roller 300 are on the same straight line, thereby improving the disassembly or installation efficiency.

[0087] In the second position, the second limiting portion 410 is spaced from the first limiting portion 311. It can be understood that at this time, there is a gap between the limiting member 400 and the cleaning roller 300 for releasing the restriction on the cleaning roller 300, that is, the cleaning roller 300 can rotate relative to the housing 100. In addition, during the installation or disassembly process, the user can also rotate the cleaning roller 300 to adjust the disassembly angle or installation angle of the cleaning roller 300, and adjust the disassembly position or installation position of the cleaning roller 300.

[0088] It should be noted that when the user installs the cleaning roller 300 in the roller groove 110 or disassembles it from the roller groove 110, the limiting member 400 is rotated to the first position to fix the cleaning roller 300 through the limiting member 400. At this time, the user can install or disassemble the side of the cleaning roller 300 facing away from the first limiting member 400. After the installation or disassembly is completed, the limiting member 400 can be rotated to the second position, and the cleaning roller 300 can be rotated to adjust the installation or disassembly angle of the cleaning roller 300, and then the limiting member 400 is rotated to the first position to facilitate the installation or disassembly of the other circumferential side of the connecting end 310 of the cleaning roller 300, so as to improve the convenience and stability of the installation or disassembly of the cleaning roller 300.

[0089] That is to say, by rotating the limiting member 400, the limiting member 400 can switch between the first position and the second position. When it is necessary to install or disassemble the cleaning roller 300, the limiting member 400 is moved to the first position to form a limiting structure by connecting the first limiting portion 311 and the second limiting portion 410 to prevent the cleaning roller 300 from rotating, thereby ensuring the stability of the disassembly of the cleaning roller 300 and improving the disassembly efficiency; by adjusting the limiting member 400 to the second position, it is convenient to adjust the angle of the cleaning roller 300 or clean the ground through the cleaning roller 300.

[0090] As Figure 2 shown, in some embodiments of the present application, the first limiting portion 311 includes at least one first tooth-engaging portion 3111. It can be understood that the number of the first tooth-engaging portions 3111 can be one, two or more than two, and can be specifically set according to the actual situation.

[0091] In this embodiment, the number of the first tooth-engaging portions 3111 is multiple, and the multiple first tooth-engaging portions 3111 are arranged along the outer periphery of the connecting end 310, and the second limiting portion 410 is a second tooth-engaging portion.

[0092] In the first position, at least a part of the first tooth-engaging portion 3111 meshes with the second tooth-engaging portion, that is, the first limiting portion 311 and the second limiting portion 410 mesh, so as to form a limiting connection structure through the connection of the first limiting portion 311 and the second limiting portion 410, so as to limit and fix the cleaning roller 300 and prevent the cleaning roller 300 from rotating.

[0093] In some embodiments, the first limiting portions 311 are multiple, and the multiple first limiting portions 311 are arranged at intervals along the outer periphery of the connecting end 310. By increasing the number of the first limiting portions 311, it is ensured that when the cleaning roller 300 rotates at any angle relative to the housing 100, at least one part of the first limiting portions 311 can be connected to the second limiting portion 410 to form a limiting structure, thereby improving the convenience of limiting the cleaning roller 300.

[0094] In addition, in some embodiments of the present application, the first limiting portion 311 includes multiple grooves, the multiple grooves are arranged at intervals along the outer periphery of the connecting end 310, the second limiting portion 410 includes multiple first protrusions, and one first protrusion corresponds to one groove.

[0095] In the first position, one of the first protrusions is clamped in one of the grooves to form a limiting structure, thereby preventing the cleaning roller 300 from rotating.

[0096] As Figure 2 shown, in some embodiments of the present application, the housing 100 is provided with a first opening 120 communicating with the roller groove 110, and at least a part of the first limiting portion 311 is exposed outside the first opening 120. It can be understood that when the cleaning roller 300 rotates at any angle relative to the housing 100, at least a part of the first limiting portion 311 is exposed in the first opening 120, so as to ensure that when the cleaning roller 300 rotates to any angle, the second limiting portion 410 can be connected to a part of the first limiting portion 311 to form a limiting structure, thereby ensuring the stability and efficiency of limiting the cleaning roller 300.

[0097] It should be noted that when in the first position, at least a part of the second limiting part 410 is connected to the first limiting part 311 exposed in the first opening 120 to form a limiting structure, and the connecting end 310 is limited, so as to limit the cleaning roller 300, prevent the cleaning roller 300 from rotating, and ensure the stability of the cleaning roller 300.

[0098] As Figure 2 shown, in this embodiment, the fastener 500 is a bolt, the first mounting hole 210 is a first threaded hole, the screw of the bolt passes through the first connecting hole 312, and the screw is connected to the hole wall of the first threaded hole, and the nut of the bolt abuts against the connecting end 310, so as to connect the cleaning roller 300 and the connecting ring 200 by the bolt, which can not only ensure the stability of the connection between the connecting ring 200 and the cleaning roller 300, but also facilitate installation or disassembly.

[0099] It should be noted that the top end of the nut is lower than the top end of the first limiting part 311 to prevent the nut from protruding out of the top end of the first limiting part 311 to form an obstruction, ensure the smoothness of the top end of the first limiting part 311, and ensure the smoothness during the rotation of the cleaning roller 300.

[0100] As Figures 4 to 6 shown, in some embodiments of the present application, the limiting member 400 is pivotally connected to the housing 100 to form a pivoting portion 440, and the limiting member 400 can rotate relative to the housing 100 so that the limiting member 400 can be switched between the first position and the second position.

[0101] In some embodiments, the limiting member 400 is disposed on a side of the housing 100 away from the cleaning roller 300, the limiting member 400 is rotatably connected to the housing 100, and the limiting member 400 is disposed at one end of the housing 100 close to the first opening 120.

[0102] As Figures 4 to 6 shown, in some embodiments of the present application, the housing 100 is provided with a first positioning structure 150, and one end of the limiting member 400 away from the pivoting portion 440 is provided with a second positioning structure 420.

[0103] When in the first position, the first positioning structure 150 and the second positioning structure 420 cooperate with each other to position the limiting member 400 on the housing 100, so that the first limiting part 311 and the second limiting part 410 are connected to form a limiting connection structure, and the cleaning roller 300 is limited by the limiting member 400, thereby ensuring the stability of the cleaning roller 300.

[0104] Among them, one of the first positioning structure 150 and the second positioning structure 420 is a positioning groove, and the other is a positioning protrusion, that is, when in the first position, the positioning protrusion is accommodated in the positioning groove, and the positioning groove provides the positioning protrusion with a giving way and positioning function to ensure the accuracy and stability of the limit member 400 rotating to the first position relative to the shell 100.

[0105] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, the first positioning structure 150 is a positioning groove, the second positioning structure 420 is a positioning protrusion, and the cleaning device includes a roller cover 700, which is detachably connected to the bottom of the housing 100 at a position corresponding to the roller groove 110, and is used to limit the position of the cleaning roller to prevent it from falling. When the user needs to clean the cleaning roller, they first need to remove the roller cover 700, take out the cleaning roller for cleaning, then return it to the roller groove 110, and then install the roller cover 700. The connection method between the roller cover 700 and the housing 100 includes any one of a snap connection, a fastener connection, and a magnetic connection, which can be specifically set according to actual conditions.

[0106] When the roller cover 700 is installed on the side of the shell 100 facing the cleaning roller 300, a portion of the roller cover 700 presses the positioning protrusion, lifts the positioning protrusion from the positioning groove, and disengages the positioning protrusion from the positioning groove, thereby switching the limit member 400 from the first position to the second position.

[0107] like Figure 4 、 Figure 5 As shown, in some embodiments of the present application, the housing 100 is provided with a first connecting portion 130, the limiting member 400 is provided with a second connecting portion 430, and the first connecting portion 130 and the second connecting portion 430 are connected by an elastic member 600. It should be noted that the elastic member 600 is used to switch the limiting member 400 from the second position to the first position.

[0108] In this embodiment, when the limiting member 400 is at the first position and the second position, the elastic member 600 is in a stretched state, that is, the elastic member 600 stores elastic potential energy.

[0109] The first connection portion 130 and the second connection portion 430 are both close to the second positioning structure 420. It is understandable that when the limiting member 400 switches from the first position to the second position, the distance between the first connection portion 130 and the second connection portion 430 increases, and the elastic member 600 extends; when the limiting member 400 switches from the second position to the first position, the distance between the first connection portion 130 and the second connection portion 430 decreases, and the elastic member 600 contracts.

[0110] When the roller cover 700 moves away from the housing 100 towards the side of the cleaning roller 300, the elastic member 600 returns to its original position, causing the limiting member 400 to switch from the second position to the first position under the elastic force of the elastic member 600, so as to drive the positioning protrusion to cooperate with the positioning groove, that is, to drive the first positioning structure 150 and the second positioning structure 420 to cooperate.

[0111] It should be noted that when the limiting member 400 is in the second position under the action of an external force, the elastic member 600 is in a stretched state and stores elastic potential energy. That is, the elastic member 600 exerts a pulling force on the limiting member 400 in the direction close to the housing 100. That is, the second connecting portion 430 has a tendency to move in the direction close to the first connecting portion 130 under the elastic force of the elastic member 600. And when the external force acting on the limiting member 400 is removed, the limiting member 400 switches from the second position to the first position under the elastic force of the elastic member 600. That is, the second connecting portion 430 moves towards the first connecting portion 130 to form a limit on the cleaning roller 300 through the limiting member 400.

[0112] Among them, the elastic member 600 can be a spring or an elastic rubber. In this embodiment, the elastic member 600 is a spring.

[0113] It should be noted that by providing a positioning protrusion on the limiting member 400, when the roller cover 700 is installed on the housing 100, the roller cover 700 can push up the positioning protrusion, so that the limiting member 400 switches from the first position to the second position, so that the first limiting portion 311 and the second limiting portion 410 are spaced apart, to prevent the limiting member 400 from blocking the cleaning roller 300 when the roller cover 700 is installed on the housing 100, thereby ensuring the stability and smoothness of the rotation of the cleaning roller 300 driven by the driving mechanism 800.

[0114] It can be understood that when the roller cover 700 is installed on the housing 100, that is, when the cleaning device is installed, at this time, the cleaning device can be used to clean the surface to be cleaned. That is to say, the roller cover 700 pushes up the positioning protrusion and switches the limiting member 400 from the first position to the second position to prevent the limiting member 400 from blocking the cleaning roller 300, thereby releasing the restriction on the cleaning roller 300 and ensuring the stability and smoothness of the rotation of the cleaning roller 300 driven by the driving mechanism 800.

[0115] In addition, when the cleaning roller 300 needs to be disassembled, by removing the roller cover 700 from the housing 100, at this time, since the elastic member 600 is in a stretched state and stores elastic potential energy, after the abutting force of the roller cover 700 against the positioning protrusion is cancelled, the limiting member 400 switches from the second position to the first position under the elastic force of the elastic member 600; it can be understood that at this time, the first limiting portion 311 and the second limiting portion 410 are connected to form a limiting connection structure, that is, the cleaning roller 300 is limited by the limiting member 400 to prevent the cleaning roller 300 from rotating, so that during the process of disassembling the cleaning roller 300 by the user, the cleaning roller 300 can maintain a stable state, thereby improving the disassembly efficiency and convenience of the cleaning roller 300.

[0116] In this embodiment, the roller cover 700 is provided with a relief opening so that when the roller cover 700 is installed on the housing 100, a part of the cleaning roller 300 can pass through the relief opening, and under the driving action of the driving mechanism 800, the cleaning roller 300 can rotate and clean the ground.

[0117] As Figure 5 shown, in some embodiments of the present application, a limiting platform 140 is provided on one side of the housing 100 close to the pivot portion 440, and the limiting platform 140 provides a limiting effect on the limiting member 400 to limit the rotation angle of the limiting member 400.

[0118] In the second position, one end of the limiting member 400 close to the limiting platform 140 abuts against the limiting platform 140 to limit the rotation stroke of the limiting member 400 relative to the housing 100. Specifically, the limiting platform 140 forms a limiting effect on the limiting member 400 to control the rotation angle of the limiting member 400, so as to ensure that there is a gap between the first limiting portion 311 and the second limiting portion 410 in the second position, and at the same time, the gap distance between the first limiting portion 311 and the second limiting portion 410 can be controlled to prevent the rotation angle of the limiting member 400 from being too large, reduce the space occupancy rate of the limiting member 400 in the cleaning device, and thus improve the space utilization rate of the cleaning device.

[0119] Based on any of the above embodiments, in this embodiment, the housing 100 is provided with a first connecting portion 130, and the limiting member 400 is provided with a second connecting portion 430. The first connecting portion 130 and the second connecting portion 430 are connected by an elastic member 600. It should be noted that the elastic member 600 is used to switch the limiting member 400 from the second position to the first position.

[0120] In this embodiment, when the limiting member 400 is in the first position and the second position, the elastic member 600 is in a stretched state, that is, the elastic member 600 stores elastic potential energy, that is, the elastic member 600 is used to switch the limiting member 400 from the second position to the first position.

[0121] In an embodiment of a cleaning robot, the cleaning robot includes a movable main body and a cleaning device as described in any of the above embodiments, and the cleaning device is installed on the main body.
