[0033] As shown in Figures 1 to 4 Some embodiments of the present application provide a cleaning device, mainly applied to a cleaning robot, to improve the convenience of the cleaning roller 300 during installation or disassembly, and improve the efficiency of disassembly or installation of the cleaning roller 300.

[0034] The cleaning device comprises a housing 100, a cleaning roller 300, a driving mechanism 800 and a limiting piece 400.

[0035] The housing 100 defines a roller groove 110, a retaining piece 900 and a connecting ring 200 sleeved on the retaining piece 900 and rotatable relative to the retaining piece 900 are fixed in the roller groove 110, and the retaining piece 900 is fixedly connected with the housing 100 to provide a supporting action on the connecting ring 200 through the retaining piece 900 to ensure the stability of the connecting ring 200 during rotation on the retaining piece 900.

[0036] The cleaning roller 300 is rotationally arranged in the roller groove 110, and the cleaning roller 300 has a gap between the roller groove 110 and the groove wall to ensure the smoothness of the cleaning roller 300 during rotation.

[0037] In addition, the cleaning roller 300 has a connecting end 310 and a free end 320, the connecting end 310 is fixedly connected with the connecting ring 200, and the cleaning roller 300 is supported by the retaining piece 900 to ensure the stability of the cleaning roller 300 on the retaining piece 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 retaining piece 900, i.e. the connecting end 310 can rotate relative to the housing 100 and the retaining piece 900, so that the cleaning roller 300 can rotate relative to the housing 100 and the retaining piece 900.

[0038] Specifically, the driving mechanism 800 drives the cleaning roller 300 to rotate relative to the retaining piece 900, i.e. 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.

[0039] In addition, the limiting piece 400 is movably connected to the housing 100. It should be noted that the connection between the limiting piece 400 and the housing 100 at least includes one of sliding connection, rotary connection, clamping, magnetic attraction connection, which can be specifically set according to actual conditions.

[0040] In the embodiment, the limiting member 400 is used to limit the connecting end 310 to restrict the rotation of the cleaning roller 300, so as to facilitate the fixing of the connecting end 310 and the connecting ring 200.

[0041] It should be noted that when the cleaning roller 300 is disassembled from the roller groove 110 or installed in the roller groove 110, the connecting end 310 is limited by the limiting member 400. At this time, the user can disassemble or install the cleaning roller 300 from the connecting ring 200, and during the disassembly or installation process, the cleaning roller 300 will not rotate, so as to avoid the deviation of the disassembling force of the user on the cleaning roller 300 and the stress direction of the cleaning roller 300, and ensure that the disassembling force direction of the user on the cleaning roller 300 and the stress direction of the cleaning roller 300 are in the same straight line, thereby improving the disassembly or installation efficiency.

[0042] As shown in Figure 2 In some embodiments of the present application, the outer periphery of the connecting end 310 is provided with a first limiting part 311, and the side of the limiting member 400 facing the cleaning roller 300 is provided with a second limiting part 410. The second limiting part 410 can be connected with the first limiting part 311 to form a limiting structure, so as to fix the cleaning roller 300 through the limiting structure and avoid the rotation of the cleaning roller 300, thereby ensuring the stability of the cleaning roller 300.

[0043] In the embodiment, the limiting member 400 has a first position and a second position when it moves relative to the shell 100. It can be understood that the limiting member 400 can switch between the first position and the second position during movement.

[0044] Specifically, when in the first position, the second limiting part 410 is at least partially connected with the first limiting part 311 to form a limiting structure for limiting 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 disassembling force of the user on the cleaning roller 300 and the stress direction of the cleaning roller 300 during the disassembly or installation process, and ensure that the disassembling force direction of the user on the cleaning roller 300 and the stress direction of the cleaning roller 300 are in the same straight line, thereby improving the disassembly or installation efficiency.

[0045] When in the second position, the second limiting part 410 is spaced from the first limiting part 311. It can be understood that at this time, there is a space between the limiting member 400 and the cleaning roller 300 for releasing the limitation on the cleaning roller 300, that is, the cleaning roller 300 can rotate relative to the shell 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.

[0046] It should be noted that when the user installs or dismounts the cleaning roller 300 in the roller groove 110, the limiting piece 400 is rotated to the first position to fix the cleaning roller 300 by the limiting piece 400. At this time, the user can install or dismount the side of the cleaning roller 300 away from the first limiting piece 400, and when the installation or dismounting is completed, the limiting piece 400 can be rotated to the second position, and the cleaning roller 300 is rotated to adjust the angle of installation or dismounting of the cleaning roller 300, and then the limiting piece 400 is rotated to the first position to facilitate the installation or dismounting 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 dismounting of the cleaning roller 300.

[0047] That is, the limiting piece 400 can be switched between the first position and the second position by rotating the limiting piece 400, and when the cleaning roller 300 needs to be installed or dismounted, the limiting piece 400 is moved to the first position to form a limiting structure by connecting the first limiting part 311 and the second limiting part 410, so as to prevent the cleaning roller 300 from rotating, thereby ensuring the stability of dismounting the cleaning roller 300 and improving the dismounting efficiency; by adjusting the limiting piece 400 to the second position, the angle of the cleaning roller 300 or the cleaning of the ground by the cleaning roller 300 can be adjusted.

[0048] As shown in Figure 2 In some embodiments of the present application, the first limiting part 311 includes at least one first toothed part 3111.

[0049] Optionally, in some embodiments, the first toothed part 3111 is one, which is arranged on the outer periphery of the connecting end 310.

[0050] In the present embodiment, the number of first toothed parts 3111 is multiple, and the multiple first toothed parts 3111 are arranged along the outer periphery of the connecting end 310, and the second limiting part 410 is a second toothed part.

[0051] In the first position, at least part of the first toothed part 3111 is engaged with the second toothed part, that is, the first limiting part 311 and the second limiting part 410 are engaged, so as to form a limiting connection structure by connecting the first limiting part 311 and the second limiting part 410, so as to limit and fix the cleaning roller 300, and prevent the cleaning roller 300 from rotating.

[0052] In some embodiments, the first limiting part 311 is in plurality, and the plurality of first limiting parts 311 are arranged along the outer periphery of the connecting end 310 at intervals. By increasing the number of the first limiting parts 311, it is ensured that at least one of the first limiting parts 311 can be connected with the second limiting part 410 to form the limiting structure when the cleaning roller 300 rotates at any angle relative to the shell 100, thereby improving the convenience of limiting the cleaning roller 300.

[0053] In addition, in some embodiments of the present application, the first limiting part 311 includes a plurality of grooves arranged at intervals along the outer periphery of the connecting end 310, and the second limiting part 410 includes a plurality of first protrusions, one first protrusion corresponding to one groove.

[0054] When in the first position, one first protrusion is clamped in one groove to form the limiting structure, thereby preventing the cleaning roller 300 from rotating.

[0055] As shown in Figure 2 In some embodiments of the present application, the shell 100 is provided with a first opening 120 communicating with the roller groove 110, and the first limiting part 311 is at least partially exposed to the first opening 120. It can be understood that the first limiting part 311 is at least partially exposed in the first opening 120 when the cleaning roller 300 rotates at any angle relative to the shell 100, so as to ensure that the second limiting part 410 can be connected with part of the first limiting part 311 to form the limiting structure when the cleaning roller 300 rotates to any angle, thereby ensuring the stability and efficiency of limiting the cleaning roller 300.

[0056] It should be noted that when in the first position, the second limiting part 410 is at least partially connected with the first limiting part 311 exposed to the first opening 120 to form the limiting structure, and forms a limiting action on the connecting end 310, thereby forming a limiting action on the cleaning roller 300 to prevent the cleaning roller 300 from rotating, thereby ensuring the stability of the cleaning roller 300.

[0057] As shown in Figure 2 and Figure 5 In some embodiments of the present application, the connecting end 310 is sleeved on the connecting ring 200, the outer periphery of the connecting ring 200 is provided with at least one first mounting hole 210, the outer periphery of the connecting end 310 is provided with at least one first connecting hole 312, and the first mounting hole 210 and the first connecting hole 312 are arranged correspondingly.

[0058] The number of the first mounting hole 210 and the number of the first connecting hole 312 can be one, two or any number of more than two, which can be set according to actual conditions.

[0059] In the 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.

[0060] 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 plural, the plurality of first mounting holes 210 are arranged equidistantly along the outer periphery of the connecting ring 200, the plurality of first connecting holes 312 are arranged equidistantly along the outer periphery of the connecting end 310, and one first mounting hole 210 corresponds to one first connecting hole 312.

[0061] Specifically, the connecting end 310 and the connecting ring 200 are connected through the plurality of fasteners 500, the fasteners 500 pass through the first connecting holes 312 and the first mounting holes 210 in sequence to fix the connecting end 310 to the connecting ring 200.

[0062] It can be understood that when the fastener 500 passes through the hole wall of the first connecting hole 312 and the first mounting hole 210, at this time, by adjusting the limiting piece 400 to the first position, the limiting piece 400 is used to limit the cleaning roller 300, so as to prevent the cleaning roller 300 from rotating during the tightening of the fastener 500, thereby ensuring the stability of the user in tightening the fastener 500 and the stability of the force received by the cleaning roller 300, thereby effectively improving the installation or disassembly efficiency of the cleaning roller 300.

[0063] As shown in Figure 2 In the embodiment, the fastener 500 is a bolt, the first mounting hole 210 is a first threaded hole, the shank of the bolt passes through the first connecting hole 312 and connects the shank with 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 through the bolt. Through the bolt connection, not only the stability of the connection between the connecting ring 200 and the cleaning roller 300 can be ensured, but also the installation or disassembly is facilitated.

[0064] It should be noted that the top end of the nut is lower than the top end of the first limiting part 311, so as to prevent the nut from protruding from the top end of the first limiting part 311 to form an obstacle, ensure the smoothness of the top end of the first limiting part 311, and ensure the fluency during the rotation of the cleaning roller 300.

[0065] As shown in Figure 5 In some embodiments of the present application, the outer periphery of the connecting ring 200 is provided with at least one positioning boss 220. It can be understood that the number of the positioning boss 220 can be one, two or any number of values, which can be set according to actual conditions.

[0066] It should be noted that when the number of positioning bosses 220 is multiple, the multiple positioning bosses 220 are arranged along the outer periphery of the connecting ring 200 at intervals.

[0067] The positioning boss 220 is arranged at intervals with the first mounting hole 210 to prevent the positioning boss 220 from blocking the first mounting hole 210.

[0068] In addition, the side of the connecting end 310 facing the positioning boss 220 is provided with at least one notch 313. It can be understood that the number of notches 313 can be one, two, or any number of values, which can be set according to actual conditions. It should be noted that the notch 313 is arranged at intervals with the first connecting hole 312 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.

[0069] In the present embodiment, the number of notches 313 is equal to the number of positioning bosses 220, and one positioning boss 220 is accommodated in one notch 313, and the inner wall of the notch 313 at least partially abuts the outer wall of the positioning boss 220, to form a limiting structure through the inner wall of the notch 313 and the positioning boss 220, to prevent the connecting end 310 and the connecting ring 200 from rotating relative to each other during installation between the connecting end 310 and the connecting ring 200.

[0070] It should be noted that when the positioning boss 220 is clamped in the notch 313, the first mounting hole 210 corresponds to the first connecting hole 312, that is, through the positioning boss 220 and the notch 313, a guiding and foolproof function can be provided during installation between the cleaning roller 300 and the connecting ring 200, thereby ensuring the accuracy of the installation position between the cleaning roller 300 and the connecting ring 200 and improving the installation efficiency.

[0071] As shown in the Figures 4 to 6 In some embodiments of the present application, the limiting member 400 is pivoted to the housing 100 and forms a pivot portion 440, and the limiting member 400 can rotate relative to the housing 100 to switch between the first position and the second position.

[0072] In some embodiments, the limiting member 400 is arranged on the 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 arranged on the end of the housing 100 close to the first opening 120.

[0073] As shown in the Figures 4 to 6 In some embodiments of the present application, the housing 100 is provided with a first positioning structure 150, and the end of the limiting member 400 away from the pivot portion 440 is provided with a second positioning structure 420.

[0074] In the first position, the first positioning structure 150 cooperates with the second positioning structure 420 to position the limiting piece 400 relative to the housing 100, so that the first limiting part 311 and the second limiting part 410 are connected to form a limiting connection structure, thereby limiting the cleaning roller 300 by the limiting piece 400, and ensuring the stability of the cleaning roller 300.

[0075] In some embodiments of the present application, the first positioning structure 150 is a positioning groove, and the second positioning structure 420 is a positioning protrusion. That is, in the first position, the positioning protrusion is accommodated in the positioning groove, and the positioning groove provides space and positioning for the positioning protrusion, thereby ensuring the accuracy and stability of the rotation of the limiting piece 400 to the first position relative to the housing 100.

[0076] As shown in Figure 2 and Figure 5 , in some embodiments of the present application, the first positioning structure 150 is a positioning groove, and the second positioning structure 420 is a positioning protrusion. 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 off. When the user needs to clean the cleaning roller, the roller cover 700 needs to be removed first, and then the cleaning roller is taken out for cleaning. Then it is put back into the roller groove 110, and the roller cover 700 is put back on. The connection between the roller cover 700 and the housing 100 includes any one of clamping, fastener connection, magnetic attraction connection, which can be specifically set according to the actual situation.

[0077] When the roller cover 700 is installed on the side of the housing 100 facing the cleaning roller 300, a part of the roller cover 700 presses the positioning protrusion and lifts the positioning protrusion out of the positioning groove, so that the limiting piece 400 is switched from the first position to the second position.

[0078] As shown in Figure 4 , Figure 5 , in some embodiments of the present application, the housing 100 is provided with a first connecting part 130, and the limiting piece 400 is provided with a second connecting part 430. The first connecting part 130 and the second connecting part 430 are connected by an elastic member 600. It should be noted that the elastic member 600 is used to switch the limiting piece 400 from the second position to the first position.

[0079] In this embodiment, when the limiting piece 400 is in the second position, the elastic member 600 is in a stretched state, that is, the elastic member 600 stores elastic potential energy.

[0080] The first connecting portion 130 and the second connecting portion 430 are close to the second positioning structure 420. It can be understood that when the limiting piece 400 is switched from the first position to the second position, the distance between the first connecting portion 130 and the second connecting portion 430 increases, and the elastic piece 600 is elongated; when the limiting piece 400 is switched from the second position to the first position, the distance between the first connecting portion 130 and the second connecting portion 430 decreases, and the elastic piece 600 is contracted.

[0081] When the roller cover 700 is separated from the shell 100 and is towards the side of the cleaning roller 300, the elastic piece 600 is reset, so that the limiting piece 400 is switched from the second position to the first position under the elastic force of the elastic piece 600, 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.

[0082] It should be noted that when the limiting piece 400 is in the second position under the action of the external force, the elastic piece 600 is in a stretched state and stores elastic potential energy, that is, the elastic piece 600 has a pulling force on the limiting piece 400 in the direction of approaching the shell 100, that is, the second connecting portion 430 has a tendency to move in the direction of approaching the first connecting portion 130 under the elastic force of the elastic piece 600; and when the external force acting on the limiting piece 400 is removed, the limiting piece 400 is switched from the second position to the first position under the elastic force of the elastic piece 600, that is, the second connecting portion 430 moves towards the first connecting portion 130, to form limiting on the cleaning roller 300 through the limiting piece 400.

[0083] The elastic piece 600 can be a spring or elastic rubber. In the embodiment, the elastic piece 600 is a spring.

[0084] It should be noted that by providing the positioning protrusion on the limiting piece 400, when the roller cover 700 is installed on the shell 100, the positioning protrusion can be lifted by the roller cover 700, so that the limiting piece 400 is switched 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 piece 400 from blocking the cleaning roller 300 when the roller cover 700 is installed on the shell 100, thereby ensuring the stability and smoothness of the rotation of the cleaning roller 300 under the driving of the driving mechanism 800.

[0085] It can be understood that when the roller cover 700 is installed on the shell 100, that is, the cleaning device is completed, at this time, the cleaning device can be used to clean the surface to be cleaned, that is, the positioning protrusion is lifted by the roller cover 700, and the limiting piece 400 is switched from the first position to the second position, to prevent the limiting piece 400 from blocking the cleaning roller 300, thereby releasing the limitation on the cleaning roller 300, and ensuring the stability and smoothness of the rotation of the cleaning roller 300 under the driving of the driving mechanism 800.

[0086] Furthermore, when the cleaning roller 300 needs to be disassembled, the roller cover 700 is removed from the housing 100. At this time, since the elastic member 600 is in a stretched state and stores elastic potential energy, the abutment force of the roller cover 700 against the positioning protrusion is removed, and 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 part 311 and the second limiting part 410 are connected to form a limiting connection structure, that is, the limiting member 400 limits the cleaning roller 300 to prevent the cleaning roller 300 from rotating, so that the cleaning roller 300 can maintain a stable state during the disassembly process, thereby improving the disassembly efficiency and convenience of the cleaning roller 300.

[0087] In this embodiment, the roller cover 700 has a clearance opening so that when the roller cover 700 is installed on the housing 100, a portion of the cleaning roller 300 can pass through the clearance opening, and the cleaning roller 300 can rotate and clean the ground under the driving action of the drive mechanism 800.

[0088] like Figure 5 As shown, in some embodiments of this application, a limiting platform 140 is provided on the side of the housing 100 near the pivot portion 440. The limiting platform 140 provides a limiting effect on the limiting member 400 to limit the rotation angle of the limiting member 400.

[0089] In the second position, the end of the limiting member 400 near the limiting platform 140 abuts against the limiting platform 140 to limit the travel of the limiting member 400 relative to the housing 100. Specifically, the limiting platform 140 provides a limiting effect on the limiting member 400 to control the rotation angle of the limiting member 400, thereby ensuring that there is a gap between the first limiting part 311 and the second limiting part 410 in the second position. At the same time, the gap distance between the first limiting part 311 and the second limiting part 410 can be controlled to prevent the rotation angle of the limiting member 400 from being too large, reduce the space occupancy of the limiting member 400 in the cleaning device, and thus improve the space utilization rate of the cleaning device.

[0090] Based on 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.

[0091] When the limiting member 400 is in 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.

[0092] like Figure 3 As shown, in some embodiments of this application, the drive mechanism 800 is disposed on the side of the housing 100 near the connection end 310, and the drive mechanism 800 is used to drive the cleaning roller 300 to rotate.

[0093] The drive mechanism 800 includes a drive motor 810, a transmission device 820, and a drive shaft 830. Additionally, the cleaning device includes a bearing 1000.

[0094] It should be noted that the inner ring of the bearing 1000 is fixedly sleeved on the retaining member 900, so that the retaining member 900 provides support and fixation for the bearing 1000. Additionally, the outer ring of the bearing 1000 is fixed inside 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 retaining member 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 retaining member 900.

[0095] In addition, the output end of the drive motor 810 is connected to the drive shaft 830 through the transmission device 820, that is, the output end of the drive motor 810 can drive the drive shaft 830 to rotate synchronously through the transmission device 820 during the rotation process.

[0096] Specifically, the drive shaft 830 passes through the retainer 900 and is coaxially positioned and inserted into the cleaning roller 300, so that the cleaning roller 300 rotates simultaneously with the drive shaft 830. By using a rotatable connection between the retainer 900 and the cleaning roller 300, and by inserting the drive shaft 830 into the cleaning roller 300, the cleaning roller 300 can be stably rotated around its own axis under the constraints of the retainer 900 and the drive shaft 830. The cleaning roller 300 is less prone to shaking during rotation, resulting in better stability.

[0097] In addition, some embodiments of this application provide a cleaning robot, which includes a movable host and a cleaning device as described in any of the above embodiments, the cleaning device being mounted on the host.

[0098] It should be noted that the cleaning robot provided in this embodiment has the structure and beneficial effects of the cleaning device described in any of the above embodiments, which will not be repeated here.

[0099] In addition, some embodiments of this application provide a method for detecting the installation position of a roller cover 700 on the housing 100 of the cleaning device of the cleaning robot as described in any of the above embodiments.

[0100] When the roller cover 700 is not installed in place, the limiting piece 400 limits the connection end 310, causing the rotation of the cleaning roller 300 to be limited, the drive motor 810 of the driving mechanism 800 to be blocked, and the cleaning robot to issue an alarm prompt.

[0101] In addition, when the roller cover 700 is installed in place, the limiting piece 400 is switched from the first position to the second position, so that the first limiting part 311 and the second limiting part 410 are spaced apart, to prevent the limiting piece 400 from blocking the cleaning roller 300, and the drive motor 810 can operate normally, thereby ensuring the stability and smoothness of the rotation of the cleaning roller 300 under the drive of the driving mechanism 800.

[0102] In all the examples shown and described here, any specific values should be interpreted as merely exemplary, not as limiting, so other examples of the exemplary embodiments can have different values.

[0103] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0104] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as limiting the scope of the present application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
