An embodiment of the present disclosure provides a cleaning apparatus. The cleaning apparatus includes an apparatus body and the above-mentioned cleaning floor brush. The cleaning floor brush is mounted at the apparatus body.
In the eccentric rotating device according to the embodiments of the present disclosure, since the actuator is disposed at the first rotating assembly and the follower is disposed at the second rotating assembly, in an assembling process, the first rotating assembly and the second rotating assembly are rotated relative to each other by a predetermined angle to enable the actuator and the follower to be offset by a predetermined distance, and the first rotating assembly and the second rotating assembly are brought close to each other and then rotated relative to each other by a predetermined angle, so that the actuator and abuts against the follower offset from the actuator. As a result, power of the first rotating assembly can be transmitted to the follower through the actuator, and the second rotating assembly is driven to rotate by the follower. In the assembling process, the first rotating assembly and the second rotating assembly rotate with each other and move as a whole, achieving the abutment of the actuator against the follower, to transmit power between the first rotating assembly and the second rotating assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS
It should be noted that embodiments of the present disclosure and features in the embodiments may be combined with each other without any conflict, and detailed description in specific implementations should be construed as an explanation of a purpose of the present disclosure and should not be regarded as an improper restriction on the present disclosure.
As part of the creative concept of the present disclosure, it is necessary to analyze a reason why a convenient installation of an eccentric rotating device of a cleaning apparatus is not easy in the related art before describing the embodiments of the present disclosure, and to obtain technical solutions of the embodiments of the present disclosure through the reasonable analysis.
In the related art, referring to FIG. 1, an eccentric rotating device of a cleaning floor brush includes a first rotating assembly 1, a second rotating assembly 3, and a linkage mechanism 400. The first rotating assembly 1 is rotatable about a first rotation centerline 11. The second rotating assembly 3 is rotatable about a second rotation centerline 31. The linkage mechanism 400 includes a first bar 401, a second bar 402, and a connection member 403 connected to each of the first bar 401 and the second bar 402. The first rotating assembly 1 is rotatably arranged around the first bar 401. The second rotating assembly 3 is rotatably arranged around the second bar 402. During the rotation of the first rotating assembly 1 around the first rotation centerline 11, the first rotating assembly 1 drives the second rotating assembly 3 to rotate about the second rotation centerline 31 through the linkage mechanism 400, to enable a cleaning portion 13 of the first rotating assembly 1 to partially move into or out of an outer sleeve 36 of the second rotating assembly 3, so that an object to be cleaned is cleaned and an entanglement on the cleaning portion 13 of the first rotating assembly 1 is removed. However, in an assembling process, the first bar 401 can be assembled into a corresponding hole at the first rotating assembly 1 by aligning the first bar 401 with the corresponding hole at the first rotating assembly 1, and the second bar 402 can be assembled into a corresponding hole at the second rotating assembly 3 by aligning the second bar 402 with the corresponding hole at the second rotating assembly 3. It is necessary to align the holes twice to assemble one linkage mechanism. In addition, the first rotating assembly 1 and the second rotating assembly 3 may rotate due to their unintentional contact. It is troublesome to align the first bar 401 with the corresponding hole and align the second bar 402 with the corresponding hole. When a plurality of linkage mechanisms 400 is provided, it is necessary to assemble the plurality of linkage mechanisms 400 separately. Therefore, the assembling process is cumbersome and there is a difficulty in the assembling.
In view of this, embodiments of the present disclosure provide a cleaning apparatus. The cleaning apparatus includes an apparatus body and a cleaning floor brush mounted at the apparatus body. The cleaning floor brush mounted at the apparatus body is configured to clean the object to be cleaned.
In one embodiment, the object to be cleaned may be a floor.
In one embodiment, the cleaning apparatus may be a floor sweeper.
It can be understood that the object to be cleaned is not limited to the floor, the cleaning apparatus is not limited to the floor sweeper, and no specific restrictions are imposed in the embodiments of the present disclosure.
The cleaning floor brush of the embodiment of the present disclosure includes a floor brush body 200, a driver 300, and an eccentric rotating device. The driver 300 is mounted at the floor brush body 200, and the eccentric rotating device is rotatably connected to the floor brush body 200.
In one embodiment, the driver 300 provides power for the eccentric rotating device, and the eccentric rotating device is driven by the driver 300 to rotate, so that the floor is cleaned.
In one embodiment, the driver 300 is mounted in the floor brush body 200.
In one embodiment, referring to FIG. 4, the driver 300 includes a power member 301, a drive wheel 302, and a transmission belt 303. The power member 301 provides power to the drive wheel 302 to enable the drive wheel 302 to rotate, and the rotating drive wheel 302 transmits the power to the eccentric rotating device through the transmission belt 303.
In one embodiment, the transmission belt 303 may be a synchronous belt.
In one embodiment, the power member 301 may be a motor.
Referring to FIGS. 2 to 4, and FIGS. 9 and 10, an eccentric rotating device of embodiments of the present disclosure includes a first rotating assembly 1 and a second rotating assembly 3. The first rotating assembly 1 has a first rotation centerline 11, and the first rotating assembly 1 is rotatable about the first rotation centerline 11. The second rotating assembly 3 has a second rotation centerline 31 spaced apart from the first rotation centerline 11, and the second rotating assembly 3 is rotatable about the second rotation centerline 31.
It should be noted that the first rotation centerline 11 and the second rotation centerline 31 are spaced apart from each other, which can be construed as the first rotation centerline 11 and the second rotation centerline 31 are roughly parallel to each other and basically do not cross each other, and the first rotation centerline 11 and the second rotation centerline 31 are not coaxial.
In one embodiment, the first rotating assembly 1 is rotatable about the first rotation centerline 11, the second rotating assembly 3 is rotatable about the second rotation centerline 31, and the first rotation centerline 11 and the second rotation centerline 31 are spaced by a predetermined distance.
In one embodiment, referring to FIG. 4, the rotating drive wheel 302 transmits power to the first rotating assembly 1 through the transmission belt 303.
In one embodiment, referring to FIGS. 3, 4, 9, and 10, the eccentric rotating device further includes a converter 2. The converter 2 is arranged around the first rotating assembly 1. The converter 2 has a conversion surface 21 surrounding the first rotation centerline 11, and the second rotating assembly is arranged around the conversion surface 21. The conversion surface 21 surrounds the second rotation centerline 31. In this structure, the converter 2 supports the first rotating assembly 1 and the second rotating assembly 3 to rotate about the corresponding rotation centerlines.
In one embodiment, referring to FIGS. 9 and 10, the conversion surface 21 is a torus surface, and the torus surface has an axis coinciding with the second rotation centerline 31.
In one embodiment, referring to FIG. 3, the eccentric rotating device is rotatably connected to the floor brush body 200.
In one embodiment, referring to FIG. 3, the eccentric rotating device is rotatably supported at the floor brush body 200. In this way, the eccentric rotating device is supported by the floor brush body 200, to keep the position of the first rotation centerline 11 and the position of the second rotation centerline 31 in the eccentric rotating device basically unchanged. Thus, a rotation of the second rotation centerline 31 about the first rotation centerline 11 is prevented, to ensure that the first rotating assembly 1 can be partially movable into or out of the second rotating assembly 3 more accurately to clean the object to be cleaned and the entanglement on the first rotating assembly 1.
In one embodiment, the first rotating assembly 1 is rotatably connected to the floor brush body 200.
In one embodiment, the first rotating assembly 1 is rotatably supported at the floor brush body 200.
In one embodiment, the second rotating assembly 3 is rotatably connected to the floor brush body 200.
In one embodiment, the second rotating assembly 3 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIG. 3, the first rotating assembly 1 is rotatably connected to the driver 300 to enable the driver 300 to drive the first rotating assembly 1 to rotate about the first rotation centerline 11. In this structure, the driver 300 provides power, so that the first rotating assembly 1 is driven to be rotated.
In one embodiment, referring to FIGS. 4 to 8. The eccentric rotating device further includes an actuator 12 and a follower 32. The actuator 12 is disposed at the first rotating assembly 1. The follower 32 is disposed at the second rotating assembly 3. The actuator 12 is configured to partially abut with the follower 32 to enable the first rotating assembly 1 to drive the second rotating assembly 3 to rotate. In this structure, since the actuator 12 is disposed at the first rotating assembly 1 and the follower 32 is disposed at the second rotating assembly 3, in the assembling process, the first rotating assembly 1 and the second rotating assembly 3 are rotated relative to each other by a predetermined angle to enable the actuator 12 and the follower 32 to be offset by a predetermined distance, and the first rotating assembly 1 and the second rotating assembly 3 are brought close to each other, and then are rotated relative to each other by a predetermined angle to enable the actuator 12 to abut with the follower 32 offset from the actuator 12. As a result, power of the first rotating assembly 1 can be transmitted to the follower 32 through the actuator 12, and then the follower 32 drives the second rotating assembly 3 to rotate. In the assembling process, the first rotating assembly 1 and the second rotating assembly 3 rotate with each other and move as a whole, achieving the abutment of the actuator 12 against the follower 32, to transmit power between the first rotating assembly 1 and the second rotating assembly 3. As a result, an assembling operation of the eccentric rotating device is simplified, and the convenient installation of the eccentric rotating device can be facilitated.
It can be understood that the actuator 12 and the follower 32 may always be in the abutted state, but the embodiments of the present disclosure are not limited to the actuator 12 and the follower 32 always being in the abutted state. For example, the actuator 12 may abut with the follower 32 during operation of the eccentric rotating device, and the actuator 12 may be separated from the follower 32 when the eccentric rotating device stops its operation. For example, the first rotating assembly 1 drives the actuator 12 to rotate a predetermined angle about the first rotation centerline 11 to enable the actuator 12 to abut with the follower 32, and the first rotating assembly 1 drives the actuator 12 to rotate in the opposite direction about the first rotation centerline 11 by a predetermined angle to enable the actuator 12 to be separated from the follower 32.
It can be understood that since the actuator 12 drives the follower 32 to move, the first rotating assembly 1 rotatable about the first rotation centerline 11 can drive the second rotating assembly 3 rotatable about the second rotation centerline 31 to rotate, and the first rotating assembly 1 and the second rotating assembly 3 can rotate together by driving the first rotating assembly 1 to rotate, eliminating a need to separately provide a structure for driving the first rotating assembly 1 and a structure for driving the second rotating assembly 3. As a result, the overall structure of the eccentric rotating device is more compact. In this way, miniaturization of the eccentric rotating device is facilitated.
It can be understood that the actuator 12 is kept in abutment with the follower 32 for the power transmission, and an angle of the actuator 12 rotating about the first rotation centerline 11 is almost equal to an angle of the follower 32 rotating about the second rotation centerline 31. The floor brush body 200 is used to maintain the relative position between the first rotation centerline 11 and the second rotation centerline 31. The first rotating assembly 1 is abutted against the follower 32 disposed at the second rotating assembly 3 through the actuator 12 to drive the second rotating assembly 3 to rotate. As a result, an angular velocity of the first rotating assembly 1 rotating about the first rotation centerline 11 is roughly equal to an angular velocity of the second rotating assembly 3 rotating about the second rotation centerline 31. Thus, it is ensured that the first rotating assembly 1 can be partially movable into or out of the second rotating assembly 3.
In one embodiment, referring to FIG. 3, the driver 300 drives the first rotating assembly 1 to rotate about the first rotation centerline 11, the first rotating assembly 1 drives a corresponding follower 32 abutting against actuator 12 to move through the actuator 12, and the follower 32 drives the second rotating assembly 3 to rotate, so that the first rotating assembly 1 driven by the driver 300 and rotating about the first rotation centerline 11 drives the second rotating assembly 3 to rotate about the second rotation centerline 31.
In one embodiment, referring to FIGS. 5 to 8, the eccentric rotating device includes a plurality of actuators 12 arranged in a circumferential direction of the first rotation centerline 11, and the eccentric rotating device includes a plurality of followers 32 arranged in a circumferential direction of the second rotation centerline 31 and in one-to-one correspondence with the plurality of actuators 12. In this structure, the arrangement of the actuators 12 and the arrangement of the followers 32 are simple, which reduces a difficulty in manufacturing the eccentric rotating device.
It should be noted that the “plurality of” means two or more than two. Exemplarily, the eccentric rotating device may include 2, 5, 7, or 10 actuators, but which is not limited thereto.
It should be noted that the actuators 12 and the followers 32 are in one-to-one correspondence, and equally provided. Exemplarily, referring to FIG. 8, the eccentric rotating device includes 7 actuators 12 and 7 followers 32.
Exemplarily, referring to FIG. 8, the eccentric rotating device includes a plurality of actuators 12 arranged in a circumferential direction of the first rotation centerline 11, and the eccentric rotating device includes a plurality of followers 32 arranged in a circumferential direction of the second rotation centerline 31. FIG. 8 shows two circles represented by dotted lines. The circle represented by the dotted line that coincides with a center of the actuators 12 is a first circle. The first circle has a center coinciding with the first rotation centerline 11. The circle represented by the dotted line that coincides with a center of the followers 32 is a second circle. The second circle has a center coinciding with the second rotation centerline 31.
In one embodiment, referring to FIG. 8, the eccentric rotating device includes a plurality of actuators 12 uniformly arranged in a circumferential direction of the first rotation centerline 11, and the eccentric rotating device includes a plurality of followers 32 uniformly arranged in a circumferential direction of the second rotation centerline 31. With this structure, the uniform arrangement of the actuators 12 and the uniform arrangement of the followers 32 are simple, which reduces the difficulty in manufacturing the eccentric rotating device. The uniform arrangement can ensure that at least one actuator 12 can drive the follower 32 to move, to prevent a direction of a force of the actuators 12 abutting against the corresponding followers 32 from being too close to the second rotation centerline 31, which causes a difficulty for the actuator 12 to drive the follower 32 to rotate about the second rotation centerline.
It should be noted that a center angle of two adjacent actuators 12 of the plurality of actuators 12, with the first rotation centerline 11 as a center, is a first angle. The plurality of actuators 12 is uniformly arranged in the circumferential direction of the first rotation centerline 11, which means that any two first angles are equal, and a sum of the first angles is 360°. Exemplarily, the eccentric rotating device includes 7 actuators 12, and 7 first angles are formed by the 7 actuators 12 and the first rotation centerline 11. Each of the 7 first angles is 360°/7, and a sum of the 7 first angles is 360°.
It should be noted that a central angle of two adjacent followers 32 of the plurality of followers 32, with the second rotation centerline 31 as a center, is a second angle. The plurality of followers 32 is uniformly arranged in the circumferential direction of the second rotation centerline 31, which means that any two second angles are equal, and a sum of the second angles is 360°. Exemplarily, the eccentric rotating device includes 7 followers 32, and 7 second angles are formed by the 7 followers 32 and the second rotation centerline 31. Each of the 7 second angles is 360°/7, and a sum of the 7 second angles is 360°.
In one embodiment, referring to FIG. 8, the actuator 12 has an outer surface capable of abutting with an outer surface of the follower 32. With this structure, the actuator 12 abuts against the follower 32 through their corresponding outer surfaces. The actuator 12 does not need to encircle the follower 32, and the follower 32 does not need to encircle the actuator 12. The actuator 12 and the follower 32 may be made smaller, facilitating a reduction in costs. Furthermore, the actuator 12 abuts against the follower 32 through their corresponding outer surfaces, without a need of the connection member 403 to connect the actuator 12 and the follower 32, which can simplify the structure and reduce the costs to a certain extent.
In one embodiment, the actuator 12 has an outer surface partially abutting with an inner surface of the follower 32.
In one embodiment, the actuator 12 has an inner surface abutting with an outer surface of the follower 32.
In one embodiment, referring to FIG. 8, each of the actuator 12 and the follower 32 is in a cylindrical shape. With this structure, the cylindrical actuator 12 and the cylindrical follower 32 are simple in structure and easy to manufacture.
Exemplarily, referring to FIGS. 7 and 8, the actuator 12 is in a cylindrical shape. When projected along the first rotation centerline 11, a circle represented by a dotted line coinciding with a center of the actuators 12 is a first circle, and the center of the first circle coincides with the first rotation centerline 11.
Exemplarily, referring to FIGS. 7 and 8, the follower 32 is in a cylindrical shape. When projected along the second rotation centerline 31, a circle represented by a dotted line coinciding with a center of the followers 32 is a second circle, and the center of the second circle coincides with the second rotation centerline 31.
In one embodiment, referring to FIGS. 7 and 8, a predetermined distance exists between the first rotation centerline 11 and the second rotation centerline 31. It should be explained that the distance between the first rotation centerline 11 and the second rotation centerline 31 is the predetermined distance, that is, the first rotation centerline 11 and the second rotation centerline 31 do not overlap or intersect each other, and the predetermined distance is not 0.
In one embodiment, referring to FIGS. 10 to 12, a sum of a diameter of the actuator 12 and a diameter of the follower 32 is smaller than or equal to twice the predetermined distance. This structure avoids the problem of large friction between the actuator 12 and the follower 32 caused by large interference between the actuator 12 and the follower 32, facilitating a reduction in wear between the actuator 12 and the follower 32 caused by the large friction.
Exemplarily, referring to FIGS. 10 to 12, the predetermined distance is D1; each of the actuator 12 and the follower 32 is in the cylindrical shape; the diameter of the actuator 12 is D2; the diameter of the follower 32 is D3; and D2+D3≤2*D1. It should be noted that the symbol “*” in the equality is multiplication in mathematics.
In one embodiment, referring to FIGS. 10 to 12, a sum of a diameter of the actuator 12 and a diameter of the follower 32 is greater than or equal to 1.7 times the predetermined distance. This structure can keep the actuator 12 in abutment with the follower 32 in the rotation process. As a result, the first rotating assembly 1 can drive the second rotating assembly 3 to rotate better, to prevent disengagement between the actuator 12 and the follower 32 as much as possible.
For example, referring to FIGS. 10 to 12, each of the actuator 12 and the follower 32 is in the cylindrical shape; the predetermined distance is D1; the diameter of the actuator 12 is D2; the diameter of the follower 32 is D3; and D2+D3≥1.7*D1. It should be noted that the symbol “*” in the equality is multiplication in mathematics.
In one embodiment, the diameter of the actuator 12 may be equal to, greater than, or smaller than the diameter of the follower 32.
It can be understood that the relation between the diameter of the actuator 12 and the diameter of the follower 32 may be selected as desired.
In one embodiment, the actuator 12 is a first gear, and the follower 32 is a second gear externally meshed with the corresponding first gear. The first rotating assembly 1 and the second rotating assembly 3 can transmit motion satisfactorily with the first gear externally meshed with the second gear, which facilitates an improvement in transmission efficiency.
In one embodiment, the sum of a diameter of a dedendum circle of the first gear and a diameter of a dedendum circle of the second gear is smaller than or equal to twice the predetermined distance, and greater than or equal to 1.7 times the predetermined distance.
It can be understood that the diameter of the dedendum circle of the first gear may be greater than, smaller than, or equal to the diameter of the dedendum circle of the second gear.
In one embodiment, referring to FIGS. 4 and 13, the first rotating assembly 1 includes a cleaning portion 13 in a brush shape. The cleaning portion 13 is configured to clean the object to be cleaned.
In one embodiment, referring to FIGS. 3 and 4, the cleaning portion 13 is partially movable into or out of the second rotating assembly 3 to enable an entanglement on the cleaning portion 13 to be separated from the cleaning portion 13.
In one embodiment, referring to FIGS. 3 and 4, the second rotating assembly 3 has an operation surface 33 surrounding the first rotation centerline 11 and the second rotation centerline 31. The operation surface 33 has an operation hole 331. The cleaning portion 13 moves into or move out of the operation hole 331 to enable an entanglement on the cleaning portion 13 to be separated from the cleaning portion 13.
It can be understood that the angle velocity of the first rotating assembly 1 rotating about the first rotation centerline 11 is roughly equal to the angular velocity of the second rotating assembly 3 rotating about the second rotation centerline 31, which can ensure as much as possible that the cleaning portion 13 in the brush shape at the first rotating assembly 1 is not offset from the operation hole 331 at the second rotating assembly 3, and the cleaning portion 13 can move into or out of the operation hole 331 relatively smoothly.
In one embodiment, referring to FIGS. 3 and 4, the first rotating assembly 1 includes a transmission component 14 and a roller brush component 16. The transmission component 14 is rotatable about the first rotation centerline 11, and the actuator 12 is disposed at the transmission component 14. The roller brush component 16 is drivingly connected to the transmission component 14 to rotate with the transmission component 14. The roller brush component 16 includes a cleaning portion 13. The cleaning portion 13 can be partially movable into or out of the second rotating assembly 3 to enable an entanglement on the cleaning portion 13 to be separated from the cleaning portion 13. In this structure, the transmission component 14 drives the roller brush component 16 to rotate, the actuator 12 is disposed at the transmission component 14. Based on the transmission component 14 rotating about the first rotation centerline 11 drives the actuator 12 disposed at the transmission component 14 to rotate about the first rotation centerline 11, the actuator 12 drives the corresponding follower 32 abutting against the actuator 12 to rotate about the second rotation centerline 31, and the follower 32 disposed at the second rotating assembly 3 drives the second rotating assembly 3 to rotate about the second rotation centerline 31, that is, the transmission component 14 drives the roller brush component 16 and the second rotating assembly 3 to rotate. As a result, the roller brush component 16 and the second rotating assembly 3 are eccentrically arranged. During the rotation of the roller brush component 16 and the second rotating assembly 3, the cleaning portion 13 of the roller brush component 16 moves into or out of the second rotating assembly 3 to achieve the cleaning of the object to be cleaned and the removal of the entanglement on the cleaning portion 13.
In one embodiment, the converter 2 is rotatably arranged around the transmission component 14.
In one embodiment, referring to FIG. 3, an end of the roller brush component 16 facing away from the transmission component 14 is rotatably connected to the floor brush body 200.
In one embodiment, referring to FIG. 3, an end of the roller brush component 16 facing away from the transmission component 14 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIG. 3, the transmission component 14 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIG. 3, the transmission component 14 is rotatably connected to the floor brush body 200.
In one embodiment, referring to FIGS. 3 and 4, the transmission component 14 includes a wheel body 141 and a rotary shaft 142. The wheel body 141 is rotatable about the first rotation centerline 11. The actuator 12 is disposed at the wheel body 141. The rotary shaft 142 has an axis coinciding with the first rotation centerline 11. The rotary shaft 142 has an end connected to the wheel body 141 to enable the wheel body 141 to drive the rotary shaft 142 to rotate, and another end drivingly connected to the roller brush component 16 to enable the rotary shaft 142 to drive the roller brush component 16 to rotate. In this structure, the wheel body 141 drives the roller brush component 16 to rotate about the first rotation centerline 11 through the rotary shaft 142, and the actuator 12 disposed at the wheel body 141 rotates about the first rotation centerline along with the wheel body 141. The actuator 12 drives the follower 32 to rotate, the follower 32 disposed at the second rotating assembly 3 drives the second rotating assembly 3 to rotate about the second rotation centerline 31. In one embodiment, referring to FIGS. the cleaning portion 13 of the roller brush component 16 rotating about the first rotation centerline 11 moves into or out of the operation hole 3, which completes the cleaning of the object to be cleaned and the removal of hair entangled on the cleaning portion 13.
In one embodiment, referring to FIGS. 3 and 4, the wheel body 141 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIGS. 3 and 4, the cleaning portion 13 of the roller brush component 16 rotating about the first rotation centerline 11 moves into or out of the operation hole 331, which completes the cleaning of the object to be cleaned and the removal hair entangled on the cleaning portion 13.
In one embodiment, the converter 2 is rotatably arranged around the rotary shaft 142.
In one embodiment, the wheel body 141 and the rotary shaft 142 may be integrally formed. In one embodiment, the wheel body 141 and the rotary shaft 142 may be two independently manufactured parts, and the wheel body 141 is arranged around the rotary shaft 142
In one embodiment, referring to FIG. 3, the wheel body 141 is rotatably connected to the floor brush body 200.
In one embodiment, the wheel body 141 may be fixedly connected to the actuator 12.
It should be noted that the wheel body 141 and the actuator 12 may be two independent components to be fixedly connected to each other.
It can be understood that since the wheel body 141 and the actuator 12 are two independent components to be fixedly connected to each other, wear of the actuator 12 mainly occurs at a contact between the actuator 12 and the follower 32 and does not cause wear of an entire outer surface of the actuator 12. Therefore, the wear of the actuator 12 and the wheel body 141 is relatively small.
In one embodiment, the wheel body 141 may be embedded into the actuator 12.
It should be noted that the actuator 12 embedded into the wheel body 141 forms a tight fit with the wheel body 141 and cannot move relative to the wheel body 141, and the wheel body 141 is thus fixedly connected to the actuator 12. In this way, a reduction in the wear of the actuator 12 and the wheel body 141 is facilitated.
In one embodiment, the actuator 12 is pressed into the wheel body 141 to enable the actuator 12 to be embedded into the wheel body 141.
In one embodiment, the actuator 12 has a transition fit or an interference fit with the wheel body 141 to enable the actuator 12 and the wheel body 141 to be tightly fitted, and the actuator 12 has a nominal size slightly larger than a nominal size of the hole configured for the convenient installation of the actuator 12 and defined at the wheel body 141 to enable the actuator 12 and the wheel body 141 to be tightly fitted.
In one embodiment, the wheel body 141 and the actuator 12 are integrally formed. As such, the actuator 12 cannot move relative to the wheel body 141, and the wheel body 141 is thus fixedly connected to the actuator 12. In this way, the reduction in the wear of the actuator 12 and the wheel body 141 is facilitated. Furthermore, with the wheel body 141 and the actuator 12 integrally formed, the number of parts is reduced and unnecessary disassembling and assembling between the wheel body 141 and the actuator 12 are avoided. In one embodiment, referring to FIGS. 3 and 4, the second rotating assembly 3 includes a follower disk 34 and an outer sleeve 36. The follower disk 34 is rotatable about the second rotation centerline 31. The follower 32 is disposed at the follower disk 34. The outer sleeve 36 is drivingly connected to the follower disk 34 to rotate with the follower disk 34. The outer sleeve 36 has an axis coinciding with the second rotation centerline 31. The cleaning portion 13 partially moves into or out of the outer sleeve 36 to enable an entanglement on the cleaning portion 13 to be separated from the cleaning portion 13. In this structure, the first rotating assembly 1 rotates about the first rotation centerline 11 to drive the actuator 12 to rotate about the first rotation centerline 11, and the actuator 12 drives the follower 32 to rotate. The follower 32 disposed at the follower disk 34 drives the follower disk 34 to rotate about the second rotation centerline 31, so that the follower disk 34 drives the outer sleeve 36 drivingly connected to the follower disk 34 to rotate about the second rotation centerline 31. In the rotation process, the cleaning portion 13 of the first rotating assembly 1 partially moves in or out of the outer sleeve 36, to achieve the purpose of cleaning the object to be cleaned and the removal the entanglement on the cleaning portion 13.
In one embodiment, referring to FIGS. 3, 4, 9, and 10, the follower disk 34 is arranged around the conversion surface 21.
In one embodiment, the follower 32 is fixedly connected to the follower disk 34.
It can be understood that since the follower 32 is fixedly connected to the follower disk 34, and there is no relative movement between the follower 32 and the follower disk 34, there is no wear caused by mutual friction between the follower 32 and the follower disk 34. The wear of the follower 32 mainly occurs at the contact between the follower 32 and the actuator 12, and not cause the wear of the entire outer surface of the follower 32. Therefore, the wear of the follower 32 and the follower disk 34 is relatively small. Furthermore, due to the small wear and the follower disk 34 being hardly affected by a centrifugal load of the connection member 403 in the related art, material requirements for the follower disk 34 may be appropriately lowered to select a lower-cost material while meeting strength requirements of the product, facilitating the reduction in the costs.
In one embodiment, a material of the follower disk 34 may be POM (polyformaldehyde).
In one embodiment, the follower 32 may be embedded into the follower disk 34.
It should be noted that the follower 32 embedded into the follower disk 34 forms a tight fit with the follower disk 34, and cannot move relative to the follower disk 34, and the follower disk 34 is thus fixedly connected to the follower 32. In this way, a reduction in the wear of the follower 32 and the follower disk 34 is facilitated.
In one embodiment, the follower 32 is pressed into the follower disk 34 to enable the follower 32 to be embedded into the follower disk 34.
In one embodiment, the follower 32 has a transition fit with or an interference fit with the follower disk 34 to enable the follower 32 and the follower disk 34 to be tightly fitted, and the follower 32 has a nominal size slightly larger than a nominal size of the hole configured for the convenient installation of the follower 32 and defined at the follower disk 34 to enable the follower 32 and the follower disk to be tightly fitted.
In one embodiment, the follower 32 and the follower disk 34 are integrally formed. As such, the follower 32 cannot move relative to the follower disk 34, and the follower disk 34 is thus fixedly connected to the follower 32. In this way, the reduction in the wear of the follower 32 and the follower disk 34 is facilitated. Furthermore, with the follower 32 and the follower disk 34 integrally formed, the number of parts is reduced and unnecessary disassembling and assembling between the follower disk 34 and the follower 32 are avoided.
In one embodiment, referring to FIGS. 3 and 4, an end of the outer sleeve 36 facing away from the follower disk 34 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIGS. 3 and 4, the follower disk 34 is rotatably supported at the floor brush body 200.
In one embodiment, referring to FIGS. 3, 4, and 14, the roller brush component 16 is located in the outer sleeve 36, and the roller brush component 16 and the outer sleeve 36 are eccentrically arranged. The roller brush component 16 is rotatable about the first rotation centerline 11, and the outer sleeve 36 is rotatable about the second rotation centerline 31. The cleaning portion 13 in the brush shape of roller brush component 16 moves into or out of the outer sleeve 36 through the operation hole 331 of the outer sleeve 36.
In one embodiment, an angular velocity of the roller brush component 16 rotating about the first rotation centerline 11 is equal to an angular velocity of the outer sleeve 36 rotating around the second rotation centerline 31. As such, the cleaning portion 13 in the brush shape of the roller brush component 16 can avoid that the operation hole 331 is offset from the outer sleeve 36 as much as possible, and the cleaning portion 13 can smoothly move into or out of the outer sleeve 36 through the operation hole 331.
In one embodiment, referring to FIG. 3, an end of the outer sleeve 36 facing away from the follower disk 34 is rotatably connected to the floor brush body 200.
In one embodiment, referring to FIG. 3, the follower disk 34 is rotatably connected to the floor brush body 200.
In one embodiment, referring to FIGS. 3 and 4, the converter 2 is rotatably arranged around the rotary shaft 142, and the follower disk 34 is rotatably arranged around the conversion surface 21 of the converter 2.
In one embodiment, referring to FIGS. 9 and 10, the converter 2 includes a support assembly 22 and a bearing 23. The support assembly 22 is rotatably arranged around the first rotating assembly 1. The bearing 23 is arranged around the support assembly 22. The conversion surface 21 is formed outside of an outer ring of the bearing 23. In this structure, two different rotation centers are defined by the support assembly 22 and the bearing 23, and therefore the first rotating assembly 1 can drive the second rotating assembly 3 to rotate about the second rotation centerline 31 while rotating about the first rotation centerline 11. With the conversion surface 21 formed outside of the outer ring of the bearing 23, the second rotating assembly 3 arranged around the conversion surface 21 hardly moves relative to the conversion surface 21, which can reduce the wear between the follower disk 34 and the converter 2.
