[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0016] After extensive research, the inventors discovered that cleaning devices often incorporate cleaning elements to enhance their effectiveness. These cleaning devices also require a motor-driven cleaning element. For example, a side brush may be located at the bottom of the cleaning device, requiring a motor to drive it. In the prior art, the transmission structure between the motor and the cleaning element is inflexible, making it difficult to adjust the position or posture of the cleaning element through movement. To address this technical issue, the present application provides the following embodiments.
[0017] like Figures 1 to 4As shown, the cleaning device described in the embodiment of the cleaning device of the present application includes a device body 100, a drive motor 400, a first cleaning member 300, and a first flexible shaft 510. The drive motor 400 is disposed on the device body 100. The first cleaning member 300 is movably disposed on the device body 100. The output shaft of the drive motor 400 is transmission-connected to the first cleaning member 300 via the first flexible shaft 510. The drive motor 400 is configured to drive the first cleaning member 300 to move by driving the first flexible shaft 510.
[0018] By providing the first flexible shaft 510, it is helpful to simplify the transmission structure of the cleaning device and facilitate assembly. In addition, the first flexible shaft 510 has a certain degree of deformation ability and can bend and twist to facilitate adjustment of the torque direction and position of the transmission process. On the one hand, it is helpful to reduce the impact of the impact force exerted on the first cleaning member 300 on the drive motor 400 and play a shock-absorbing role. On the other hand, when adjusting the position or posture of the first cleaning member 300, the output shaft of the drive motor 400 and the first cleaning member 300 can still maintain a stable connection, which is beneficial to improve the structural stability and flexibility of the cleaning device and facilitate adjustment of the position or posture of the first cleaning member 300.
[0019] Alternatively, as Figures 1 to 4 As shown, the driving motor 400 is used to drive the first flexible shaft 510 to move and thereby drive the first cleaning member 300 to rotate. The first cleaning member 300 is rotatably connected to the device body 100.
[0020] With this arrangement, the output shaft of the driving motor 400 can drive the first flexible shaft 510 to twist and rotate when it rotates. The first flexible shaft 510 can transmit the rotational motion to the first cleaning member 300 to drive the first cleaning member 300 to rotate.
[0021] Alternatively, as Figure 3 As shown, the first flexible shaft 510 has a first connecting section 511 and a second connecting section 512. The first flexible shaft 510 is bent so that the first connecting section 511 and the second connecting section 512 are arranged at an angle. For example, the first connecting section 511 and the second connecting section 512 are perpendicular.
[0022] In this way, the direction of motion transmission can be changed by changing the extension direction of the first flexible shaft 510, which is beneficial for simplifying the transmission structure of the cleaning device and facilitating assembly.
[0023] In some embodiments, the first connecting section 511 and the second connecting section 512 may be located at both ends of the first flexible shaft 510. In other embodiments, the first connecting section 511 may be located at one end of the first flexible shaft 510, and the second connecting section 512 may be located between the two ends of the first flexible shaft 510.
[0024] In some embodiments, a first end of the first flexible shaft 510 is connected to the output shaft of the driving motor 400 , and a second end of the first flexible shaft 510 is connected to the first cleaning member 300 .
[0025] In this arrangement, when the output shaft of the driving motor 400 rotates, it can drive the first end of the first flexible shaft 510 to twist and rotate. The first end of the first flexible shaft 510 can transmit the rotational motion to the second end of the first flexible shaft 510, and further transmit the rotational motion to the first cleaning member 300, so as to drive the first cleaning member 300 to rotate.
[0026] Alternatively, as Figure 5 As shown, the cleaning device further includes a second cleaning member 200, which is movably disposed on the device body 100. The driving motor 400 is used to drive the second cleaning member 200 to rotate. Furthermore, the second cleaning member 200 is rotatably connected to the device body 100.
[0027] The second cleaning member 200 and the first cleaning member 300 can clean different areas, enhancing the functionality of the cleaning device and improving cleaning efficiency. Compared to using separate motors to drive the first cleaning member 300 and the second cleaning member 200, using a drive motor 400 to drive the first cleaning member 300 and the second cleaning member 200 can help reduce the number of motors required, thereby improving space utilization and reducing costs.
[0028] Optionally, the second cleaning member 200 may be the same as or different from the first cleaning member 300. For example, the second cleaning member 200 and the first cleaning member 300 may both be side brushes 301. Another example is that the second cleaning member 200 and the first cleaning member 300 may both be mops. Another example is that the second cleaning member 200 may be a roller brush 201 and the first cleaning member 300 may be a side brush 301. Another example is that the first cleaning member 300 may be a mop and the second cleaning member 200 may be a roller brush 201.
[0029] Optionally, the output shaft of the driving motor 400 is in transmission connection with the first cleaning member 300 and the second cleaning member 200 via the first flexible shaft 510. The driving motor 400 can drive the first cleaning member 300 and the second cleaning member 200 to rotate by driving the first flexible shaft 510 to move.
[0030] This helps improve the synchronization of the rotation of the first cleaning member 300 and the second cleaning member 200. For example, if the second cleaning member 200 and the first cleaning member 300 are both mops or both are side brushes 301, the synchronous movement of the second cleaning member 200 and the first cleaning member 300 is conducive to improving the cleaning effect.
[0031] Optionally, the output shaft of the driving motor 400 is in transmission connection with the second cleaning member 200 via a non-flexible shaft transmission structure. The non-flexible shaft transmission structure is a transmission structure that does not include a flexible shaft.
[0032] Such a configuration is conducive to accurately transmitting the rotation of the output shaft of the driving motor 400 to the second cleaning member 200, so as to drive the second cleaning member 200 to rotate. For example, the output shaft of the driving motor 400 drives the second cleaning member 200 to rotate through gear transmission. For another example, Figure 5 As shown, the cleaning device further includes a timing belt 600. The output shaft of the drive motor 400 is connected to the second cleaning member 200 via the timing belt 600, thereby driving the second cleaning member 200 to rotate via the timing belt 600. Specifically, the cleaning device further includes a first gear 601 and a second gear 602. The first gear 601 is fixed to the output shaft of the drive motor 400, and the second gear 602 is fixed relative to the second cleaning member 200. The timing belt 600 is meshed with the first gear 601 and the second gear 602, respectively, so that the output shaft of the drive motor 400 can drive the second cleaning member 200 to rotate.
[0033] Alternatively, as Figure 4 As shown, the cleaning device further includes a second flexible shaft 530, and the output shaft of the driving motor 400 is transmission-connected to the second cleaning member 200 via the second flexible shaft 530. The driving motor 400 can drive the second cleaning member 200 to rotate by driving the second flexible shaft 530 to move.
[0034] With this arrangement, when the output shaft of the driving motor 400 rotates, it can drive the second flexible shaft 530 to twist and rotate. The second flexible shaft 530 can transmit the rotational motion to the second cleaning member 200 to drive the second cleaning member 200 to rotate.
[0035] For example, Figure 4 As shown, the first end of the second flexible shaft 530 is connected to the output shaft of the drive motor 400, and the second end of the second flexible shaft 530 is inserted into or penetrates the second cleaning member 200 along the rotation axis of the second cleaning member 200. When the output shaft of the drive motor 400 rotates, it can drive the first end of the second flexible shaft 530 to twist and rotate. The first end of the second flexible shaft 530 can transmit the rotational motion to the second end of the second flexible shaft 530, and further transmit the rotational motion to the second cleaning member 200, so as to drive the second cleaning member 200 to rotate.
[0036] Optionally, the second flexible shaft 530 is the same as or different from the first flexible shaft 510 .
[0037] Optionally, the driving motor 400 is used to drive the first cleaning member 300 and the second cleaning member 200 to rotate relative to the device body 100 .
[0038] Optionally, the extending direction of the rotation axis of the first cleaning member 300 is parallel to the extending direction of the rotation axis of the second cleaning member 200 .
[0039] This helps improve the consistency of the rotation of the first cleaning member 300 and the second cleaning member 200. For example, if the second cleaning member 200 and the first cleaning member 300 are both mops or both side brushes 301, the consistent movement of the second cleaning member 200 and the first cleaning member 300 is conducive to improving the cleaning effect.
[0040] Alternatively, as Figures 4 to 6 As shown, the extending direction of the rotation axis L1 of the first cleaning member 300 and the extending direction of the rotation axis L2 of the second cleaning member 200 are arranged at an angle.
[0041] Because the rotation axis L1 of the second cleaning member 200 extends in a different direction than the rotation axis L2 of the first cleaning member 300, the second cleaning member 200 and the first cleaning member 300 can clean in different directions and areas, thereby enhancing the functionality of the cleaning device. For example, the first cleaning member 300 is a side brush 301, and the second cleaning member 200 is a roller brush 201. The side brush 301 can be located at the edge of the cleaning device and protrude from the device body 100 to clean the edge and corner areas of the scene to be cleaned, while the roller brush 201 is located in the middle of the bottom of the cleaning device.
[0042] Optionally, the cleaning device is used to clean the surface to be cleaned. The extending direction of the rotation axis of the first cleaning member 300 and the extending direction of the rotation axis of the second cleaning member 200 are both perpendicular to the surface to be cleaned.
[0043] For example, the second cleaning member 200 and the first cleaning member 300 are both mops or both side brushes 301, which is beneficial to increase the contact area and friction between the second cleaning member 200 and the first cleaning member 300 and the surface to be cleaned, thereby improving cleaning efficiency and cleaning effect. The surface to be cleaned can be the ground.
[0044] Optionally, the rotation axis of one of the first cleaning member 300 and the second cleaning member 200 extends in a direction intersecting the surface to be cleaned, and the rotation axis of the other of the first cleaning member 300 and the second cleaning member 200 extends in a direction parallel to the surface to be cleaned.
[0045] In this way, the second cleaning member 200 and the first cleaning member 300 can clean the surface to be cleaned in different directions and areas, thereby improving the cleaning efficiency and cleaning effect.
[0046] Optionally, the extending direction of the rotation axis of the first cleaning member 300 and the extending direction of the rotation axis of the second cleaning member 200 are both parallel to the surface to be cleaned.
[0047] For example, one of the second cleaning member 200 and the first cleaning member 300 is a roller brush 201 , which is beneficial to reducing the friction between the second cleaning member 200 and the first cleaning member 300 and the surface to be cleaned, thereby reducing rotational resistance.
[0048] Alternatively, as Figure 5 As shown, the driving motor 400 has an output shaft, which is in transmission connection with the first cleaning member 300 and the second cleaning member 200, and is used to drive the first cleaning member 300 and the second cleaning member 200 to rotate. This helps reduce the cost of the driving motor 400.
[0049] In other embodiments, the driving motor 400 has an output shaft, and the output shaft is used to drive a first cleaning member 300 to rotate. For example, the first cleaning member 300 is a side brush 301 provided only on one side.
[0050] Optionally, the drive motor 400 has two output shafts, one of which is in transmission connection with the first cleaning member 300, and the other is in transmission connection with the second cleaning member 200. One of the output shafts is used to drive the first cleaning member 300 to rotate, and the other output shaft is used to drive the second cleaning member 200 to rotate.
[0051] This helps to reduce the interference between the rotation of the second cleaning member 200 and the rotation of the first cleaning member 300 .
[0052] Optionally, the drive motor 400 has two output shafts, which are coaxially arranged and respectively disposed at two ends of the drive motor 400. The two output shafts can rotate synchronously or independently.
[0053] Optionally, at least one of the first cleaning member 300 and the second cleaning member 200 is a mop, which is used for wet cleaning of the surface to be cleaned. Wet cleaning requires the use of a cleaning liquid to clean the surface to be cleaned. For example, the cleaning liquid can be water. In another example, the first cleaning member 300 can be a mop, and the second cleaning member 200 can be a roller brush.
[0054] In some embodiments, both the first cleaning member 300 and the second cleaning member 200 are configured to work in a wet state. In other embodiments, one of the first cleaning member 300 and the second cleaning member 200 is configured to work in a wet state.
[0055] Optionally, at least one of the first cleaning member 300 and the second cleaning member 200 is a side brush 301 or a roller brush 201. The side brush 301 or roller brush 201 is used for dry cleaning of the surface to be cleaned. Dry cleaning refers to cleaning the surface to be cleaned without the need for cleaning fluid. For example, if the second cleaning member 200 is a roller brush 201, the first cleaning member 300 is a side brush 301, and the surface to be cleaned is a floor, and both the roller brush 201 and the side brush 301 are used to clean the floor, this cleaning is considered dry cleaning.
[0056] In some embodiments, both the first cleaning member 300 and the second cleaning member 200 are configured to work in a non-wet state.
[0057] Optionally, one of the first cleaning member 300 and the second cleaning member 200 is a side brush 301 or a roller brush 201. For example, the first cleaning member 300 can be a mop and the second cleaning member 200 can be a roller brush. This helps to improve the cleaning effect of the floor.
[0058] Optionally, the driving motor 400 is used to drive the first flexible shaft 510 to move so as to move the first cleaning member 300 upward and downward relative to the device body 100 .
[0059] Such arrangement is conducive to the use of the cleaning device in more scenarios. For example, the first cleaning member 300 can leave the ground through the upward movement, thereby avoiding the wet area of the ground.
[0060] The second end of the first flexible shaft 510 can be connected to the first cleaning member 300. When the first cleaning member 300 is lifted or lowered, the second end of the first flexible shaft 510 can move together with the first cleaning member 300, so that the first cleaning member 300 can maintain a stable connection with the drive motor 400 when it is lifted or lowered or floats up and down.
[0061] For example, the first cleaning member 300 can be suspended at the lower end of the first flexible shaft 510 , and the driving motor 400 can be used to drive the lower end of the first flexible shaft 510 to move up and down, and the first cleaning member 300 can move up and down along with the lower end of the first flexible shaft 510 .
[0062] Optionally, the drive motor 400 is further configured to drive the second cleaning member 200 to move up and down relative to the device body 100. Furthermore, the drive motor 400 is configured to drive the second cleaning member 200 to move up and down relative to the device body 100 by driving the second flexible shaft 530 to move.
[0063] For example, the second cleaning member 200 can be suspended at the lower end of the second flexible shaft 530 , and the driving motor 400 can be used to drive the lower end of the second flexible shaft 530 to move up and down, and the second cleaning member 200 can move up and down along with the lower end of the second flexible shaft 530 .
[0064] In some embodiments, the output shaft of the drive motor 400 is in transmission connection with the first cleaning member 300 and the second cleaning member 200 via the first flexible shaft 510. The drive motor 400 is configured to drive the first cleaning member 300 and the second cleaning member 200 to perform lifting motions by driving the first flexible shaft 510. In other embodiments, the cleaning device further comprises a second flexible shaft 530. The output shaft of the drive motor 400 is in transmission connection with the second cleaning member 200 via the second flexible shaft 530. The drive motor 400 is configured to drive the second flexible shaft 530 to perform lifting motions.
[0065] In some embodiments, the drive motor 400 is used to drive the first flexible shaft 510 to move so as to drive the first cleaning member 300 to move up and down. The drive motor 400 is also used to drive the first flexible shaft 510 to move so as to drive the first cleaning member 300 to rotate.
[0066] In some embodiments, the drive motor 400 is used to drive the second flexible shaft 530 to move so as to drive the second cleaning member 200 to move up and down. The drive motor 400 is also used to drive the second flexible shaft 530 to move so as to drive the second cleaning member 200 to rotate.
[0067] In some embodiments, the drive motor 400 is used to drive the first flexible shaft 510 and the second flexible shaft 530 to move, thereby driving the first cleaning member 300 and the second cleaning member 200 to perform lifting motion. In other embodiments, the drive motor 400 is used to drive the first flexible shaft 510 and the second flexible shaft 530 to move, thereby driving both the first cleaning member 300 and the second cleaning member 200 to rotate. In other embodiments, the drive motor 400 is used to drive the first flexible shaft 510 and the second flexible shaft 530 to move, thereby driving one of the first cleaning member 300 and the second cleaning member 200 to rotate and the other to perform lifting motion.
[0068] Different types of first flexible shafts 510 , second flexible shafts 530 , first cleaning members 300 and second cleaning members 200 may be applicable to the above transmission forms.
[0069] In some embodiments, as Figures 1 to 3 As shown, the cleaning device includes a soft shaft assembly 500, and the soft shaft assembly 500 includes a first soft shaft 510 and a second soft shaft 530. When the second cleaning member 200 is connected to the soft shaft assembly 500, it can be lifted up or moved back and forth in the direction of travel of the cleaning device. When the first cleaning member 300 is connected to the soft shaft assembly 500, it can be lifted up or moved back and forth in the direction of travel of the cleaning device or move outward.
[0070] Alternatively, as Figures 1 to 3 as well as Figure 5 As shown, the device body 100 includes a main housing 101, a roller brush housing 102, and a cleaning member housing 103. The roller brush housing 102 and the cleaning member housing 103 are respectively connected to the main housing 101. The second cleaning member 200 is a roller brush 201, which is rotatably mounted on the roller brush housing 102. The first cleaning member 300 is a side brush 301, which is rotatably mounted on the cleaning member housing 103. The drive motor 400 can be installed on the main housing 101, the roller brush housing 102, or the cleaning member housing 103.
[0071] Furthermore, the device body 100 is provided with a fan and a dust box. The dust box is arranged on the main shell 101. The main shell 101 is provided with a dust suction port connected to the dust box. The roller brush 201 is arranged at the dust suction port, and the side brush 301 is arranged on the periphery of the dust suction port. The roller brush 201 and the side brush 301 both have bristles. The garbage swept up by the roller brush 201 and the side brush 301 can be sucked into the dust box through the dust suction port under the action of the fan.
[0072] Optionally, in some embodiments, the second cleaning member 200 has a mopping function. The device body 100 is provided with a water tank to supply water to the second cleaning member 200.
[0073] Alternatively, as Figures 1 to 3 as well as Figure 5 As shown, the axis of the output shaft of the drive motor 400 extends in an angle with the axis of rotation L2 of the first cleaning member 300. For example, the axis of the output shaft of the drive motor 400 extends perpendicular to the axis of rotation L2 of the first cleaning member 300. The first flexible shaft 510 can be bent so that the first end of the first flexible shaft 510 is coaxial with the output shaft of the drive motor 400, and the second end of the first flexible shaft 510 is coaxial with the first cleaning member 300.
[0074] Furthermore, the first end of the first flexible shaft 510 may be relatively fixedly connected to the output shaft of the driving motor 400. Alternatively, the first end of the first flexible shaft 510 is connected to the output shaft of the driving motor 400 via a gear. Figure 6 As shown, the cleaning device may include a first gear 601 and a third gear 603 that are meshed with each other, the first end of the first soft shaft 510 is set on the third gear 603, and the first gear 601 is fixedly set on the output shaft of the driving motor 400, so that the output shaft of the driving motor 400 can drive the first end of the first soft shaft 510 to rotate.
[0075] Alternatively, as Figures 1 to 3 as well as Figure 5 As shown, Figures 1 to 3 as well as Figure 5 As shown, the flexible shaft assembly 500 further includes a connector 520. The connector 520 is provided with a connecting hole 523, into which the first flexible shaft 510 is inserted. The cross-section of the portion of the first flexible shaft 510 located within the connecting hole 523 matches the cross-section of the connecting hole 523 and is non-circular. The first flexible shaft 510 is connected to at least one of the first cleaning member 300 and the output shaft of the drive motor 400 via the connector 520.
[0076] The connector 520 facilitates assembly of the first flexible shaft 510. By matching the cross-section of the first flexible shaft 510 with the cross-section of the connecting hole 523 and ensuring that both are non-circular, the first flexible shaft 510 can rotate with the connector 520. For example, the cross-section of the first flexible shaft 510 and the cross-section of the connecting hole 523 can match and be rectangular.
[0077] Optionally, the side brush 301 includes a base and a brush body, the base is fixedly connected to the connector 520 , and is connected to the second end of the first flexible shaft 510 through the connector 520 .
[0078] In some embodiments, as Figures 1 to 3 as well as Figure 5 As shown, a connector 520 is provided at the first end or the second end of the first flexible shaft 510, and the first flexible shaft 510 is connected to the first cleaning member 300 and one of the output shafts of the drive motor 400 via one connector 520. In other embodiments, a connector 520 is provided at both the first end and the second end of the first flexible shaft 510, and the first flexible shaft 510 is connected to the first cleaning member 300 and the output shaft of the drive motor 400 via two connectors 520, respectively.
[0079] Alternatively, as Figures 1 to 3 as well as Figure 5 As shown, the two connectors 520 are respectively a first connector 521 and a second connector 522. The first end of the first flexible shaft 510 is connected to the output shaft of the drive motor 400 via the first connector 521, and the second end of the first flexible shaft 510 is connected to the first cleaning member 300 via the second connector 522. A bearing 104 or a rolling element is provided between the second connector 522 and the device body 100, and the second connector 522 rotates relative to the device body 100 via the bearing 104 or the rolling element.
[0080] Specifically, the cleaning device includes a bearing 104, and the device body 100 is connected to the outer ring of the bearing 104, and the second connector 522 is connected to the inner ring of the bearing 104, so that the second connector 522 can rotate relative to the device body 100 through the bearing 104. Alternatively, the cleaning device includes a rolling element, which can be a needle roller, a ball roller, etc.
[0081] With this arrangement, the device body 100 can limit the second connector 522 in a direction perpendicular to the height direction D1 of the cleaning device, while reducing the obstruction of the device body 100 to the rotation of the second connector 522, which is conducive to the smooth rotation of the second connector 522 and the first cleaning member 300.
[0082] Optionally, a mounting hole may be provided on the first connector 521 , and the output shaft of the driving motor 400 may be inserted into the mounting hole so as to be connected to the first connector 521 .
[0083] Optionally, along the height direction D1 of the cleaning device, the first cleaning member 300 and the second end of the first flexible shaft 510 are configured to be movable relative to the device body 100 .
[0084] This arrangement enables the first cleaning member 300 to move up and down, or float upward and downward, facilitating the use of the cleaning device in a variety of scenarios. For example, the first cleaning member 300 is elastically abutted against the device body 100 via a spring. When cleaning an uneven floor, the first cleaning member 300 can float up and down as the floor rises and falls, adapting to the surface. For another example, the cleaning device can be equipped with a lifting motor that can be used to drive the first cleaning member 300 to move up and down, clearing the floor and thereby avoiding wet areas.
[0085] When the first cleaning member 300 performs lifting motion or floats up and down, the second end of the first flexible shaft 510 can move together with the first cleaning member 300, and the first flexible shaft 510 can be deformed, so that the first cleaning member 300 can maintain a stable connection with the drive motor 400 when performing lifting motion or floating up and down.
[0086] Optionally, the cleaning device has a width direction perpendicular to the travel direction and height direction of the cleaning device. Along the width direction D2 of the cleaning device, the first cleaning member 300 and the second end of the first flexible shaft 510 are configured to be movable relative to the device body 100.
[0087] This arrangement enables the first cleaning member 300 to retract or expand, facilitating the use of the cleaning device in a variety of scenarios. For example, when cleaning the edge corners of a scene, the side of the device body 100 needs to maintain a distance from the edge corners of the scene along the width direction D2 of the cleaning device. The first cleaning member 300 can extend further through the expansion movement, facilitating cleaning of the edge corners of the scene. Along the width direction D2 of the cleaning device, the first cleaning member 300 can retract to reduce its size for easier storage.
[0088] Optionally, the number of the first cleaning member 300 is one.
[0089] Optionally, the number of the first cleaning members 300 is two. Figure 7As shown, the two ends of the first flexible shaft 510 are respectively connected to the two first cleaning members 300, and the two ends of the first flexible shaft 510 are connected to the output shaft of the drive motor 400, so that the drive motor 400 can drive the two first cleaning members 300 to rotate synchronously. In this arrangement, the drive motor 400 can drive the two first cleaning members 300 to rotate synchronously through the first flexible shaft 510, and can allow the two first cleaning members 300 to move up and down, move forward and backward in the direction of travel of the cleaning device, or move outward.
[0090] In other embodiments, Figure 6 As shown, the output shaft of the drive motor 400 is respectively connected to the two first cleaning members 300 via two first flexible shafts 510, so that the drive motor 400 can drive the two first cleaning members 300 to rotate synchronously. In this arrangement, the drive motor 400 can drive the two first cleaning members 300 to rotate synchronously, and can allow the two first cleaning members 300 to move up and down, move forward and backward in the direction of travel of the cleaning device, or move outward. The rotation speed of the two first cleaning members 300 can also be different by adjusting the transmission structure.
[0091] Alternatively, as Figure 8 As shown, the flexible shaft assembly 500 includes a sleeve 502 , which is sleeved on the outer circumference of the first flexible shaft 510 or the second flexible shaft 530 , and is used to guide the extension direction of the first flexible shaft 510 or the second flexible shaft 530 .
[0092] The sleeve 502 may have a higher deformation resistance than the first flexible shaft 510 or the second flexible shaft 530, so that the sleeve 502 can be used to maintain the curved shape and extension direction of the first flexible shaft 510 or the second flexible shaft 530. A gap may be provided between the sleeve 502 and the first flexible shaft 510 or the second flexible shaft 530 to allow relative movement between the sleeve 502 and the first flexible shaft 510 or the second flexible shaft 530, thereby reducing the resistance of the sleeve 502 to the rotation of the first flexible shaft 510 or the second flexible shaft 530. In some embodiments, the sleeve 502 can rotate with the first flexible shaft 510 or the second flexible shaft 530. In other embodiments, the sleeve 502 does not rotate with the first flexible shaft 510 or the second flexible shaft 530.
[0093] When the second cleaning member 200 is lifted or lowered, or floats up and down, the second end of the second flexible shaft 530 can move along with the second cleaning member 200, and the second flexible shaft 530 can deform, thereby enabling the second cleaning member 200 to maintain a stable connection with the drive motor 400 during the lifting or floating movement. Furthermore, the second flexible shaft 530 is connected to the second cleaning member 200 via the connector 520 to drive the second cleaning member 200 to rotate.
[0094] Optionally, the axis direction of the output shaft of the driving motor 400 may be parallel to the extending direction of the rotation axis L1 of the second cleaning member 200 .
[0095] To sum up, this embodiment can realize that the second cleaning member 200 and the first cleaning member 300 can clean in different directions and areas, which can enhance the functional richness of the cleaning device. Compared with setting different motors to drive the first cleaning member 300 and the second cleaning member 200, by setting a drive motor 400 to drive the first cleaning member 300 and the second cleaning member 200 to rotate, it is beneficial to reduce the number of motors set, thereby improving space utilization and reducing costs. By setting up the drive motor 400 to drive the first flexible shaft 510 and the second flexible shaft 530 to move and drive the first cleaning member 300 and the second cleaning member 200 to rotate, it is beneficial to simplify the transmission structure of the cleaning device and facilitate assembly. In addition, the first flexible shaft 510 and the second flexible shaft 530 have a certain degree of deformation ability and can bend to facilitate adjustment of the torque direction and position of the transmission process. On the one hand, it is beneficial to reduce the impact of the impact force on the first cleaning member 300 and the second cleaning member 200 on the drive motor 400, and play a shock-absorbing role. On the other hand, when adjusting the position of the first cleaning member 300 or the second cleaning member 200, the output shaft of the drive motor 400 and the first cleaning member 300 and the second cleaning member 200 can still maintain a stably connected, which is beneficial to improve the structural stability and flexibility of the cleaning device.
