Of course, they are merely examples and are not intended to limit the present invention.

In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0030] In the related art, a floor scrubber uses a motor to drive a roller brush, which rolls to scrub the working surface.

[0031] However, when the roller brush is being cleaned and working, the weight of the roller brush will increase after the bristles of the roller brush are wet.

[0032] At the same time, in order to ensure the cleaning effect, a squeezing roller is provided on the body of the floor scrubber, which is used to squeeze the roller brush to squeeze out excess water on the roller brush, so as to clean the roller brush and keep the roller brush at an appropriate dryness and wetness.

[0033] In the above-mentioned situations where the roller brush is wet, squeezed and squeezed with the machine body, the load on the motor is large. If the output torque is insufficient, the motor will have difficulty in dragging the roller brush to rotate, and the roller brush may even stop rotating, thereby affecting the use of the floor scrubber and may even cause damage to the motor.

[0034] See also Figure 1 and Figure 2 The embodiment of the present invention provides a cleaning assembly 10 . The cleaning assembly 10 includes a driving mechanism 12 and a roller brush. The driving mechanism 12 includes a motor 16 and a planetary gear mechanism 18 .

[0035] The motor 16 includes an output shaft, and the planetary gear mechanism 18 includes a first planetary gear 26 group and a second planetary gear 36 group. The first planetary gear 26 group is connected to the output shaft, and the first planetary gear 26 group is transmission-connected to the second planetary gear 36 group. The second planetary gear 36 group is connected and used to drive the roller brush to rotate.

[0036] In the above-mentioned cleaning component 10, the output shaft of the motor 16 is driven and reduced through the first planetary gear 26 group and the second planetary gear 36 group to connect and drive the roller brush to rotate. The reduction ratio is increased by the first planetary gear 26 group and the second planetary gear 36 group, thereby increasing the output torque of the roller brush driven by the second planetary gear 36 group, thereby avoiding jamming or stalling of the roller brush during rotation.

[0037] Specifically, the cleaning assembly 10 is used to be installed on a cleaning device 100 to clean a work surface. The cleaning device 100 can support and fix the cleaning assembly 10 and provide electricity, cleaning water, etc. to the cleaning assembly 10.

[0038] The cleaning assembly 10 includes a driving mechanism 12 and a roller brush. The driving mechanism 12 is in transmission connection with the roller brush and can drive the roller brush to rotate to clean the working surface.

[0039] The driving mechanism 12 includes a motor 16 and a planetary gear mechanism 18 . The output shaft of the motor 16 is connected to the planetary gear mechanism 18 , and the planetary gear mechanism 18 is connected to the roller brush, so that the motor 16 drives the roller brush.

[0040] The planetary gear mechanism 18 includes a first set of planetary gears 26 and a second set of planetary gears 36. The first set of planetary gears 26 are connected to the output shaft of the motor 16 and the second set of planetary gears 36 are connected to the roller. The first set of planetary gears 26 and the second set of planetary gears 36 decelerate the output speed of the motor 16, thereby increasing the reduction ratio and boosting the output torque of the roller brush driven by the second set of planetary gears 36.

[0041] The planetary gear mechanism 18 has high transmission efficiency, and multiple planetary gears transmit power simultaneously, so that it can withstand a large load. In addition, the planetary gear mechanism 18 has a simple and compact structure and can achieve a large reduction ratio in a small space, which is suitable for use on a small cleaning device 100.

[0042] See also Figure 2 In some embodiments, the first planetary gear 26 group includes a first sun gear 24, a first planetary gear 26, a first planetary carrier 28 and a ring gear 30. The first sun gear 24 is fixedly connected to the output shaft, the first planetary gear 26 is externally meshed with the first sun gear 24, the first planetary gear 26 is internally meshed with the ring gear 30, and the first planetary gear 26 is fixedly connected to the first planetary carrier 28.

[0043] In this way, the first planetary gear set 26 can reduce and transmit the output speed of the motor 16 .

[0044] Specifically, the first sun gear 24 is fixedly connected to the output shaft of the motor 16, and the motor 16 can drive the first sun gear 24 to rotate. The first sun gear 24 is externally meshed with the first planetary gear 26, and the ring gear 30 is covered on the outside of the first planetary gear 26. The teeth on the ring gear 30 are internally meshed with the first planetary gear 26.

[0045] The first planetary carrier 28 is fixedly connected to the first planetary gears 26. Driven by the first sun gear 24, the first planetary gears 26 rotate and orbit between the first sun gear 24 and the ring gear 30. The orbital rotation of the first planetary gears 26 drives the first planetary carrier 28 to rotate, and the first planetary carrier 28 then outputs power. The reduction ratio of the first planetary gear 26 is related to the number of teeth on the ring gear 30 and the number of teeth on the first sun gear 24.

[0046] In certain embodiments, the first planetary gear set 26 includes a plurality of first planetary gears 26 , and the plurality of first planetary gears 26 are evenly distributed along the inner circumference of the ring gear 30 .

[0047] In this way, the plurality of first planetary gears 26 can bear the load together, making the operation more stable.

[0048] Specifically, the first planetary gear 26 group includes multiple first planetary gears 26, and the multiple first planetary gears 26 are evenly distributed along the inner circumference of the ring gear 30. The load distribution between the multiple first planetary gears 26 is even, that is, the meshing force transmitted by the first sun gear 24 to the multiple first planetary gears 26 is equal, which is beneficial to improving the transmission efficiency of the planetary gear mechanism 18.

[0049] In some embodiments, the first planetary gear set 26 further includes a first friction plate 32 . The first friction plate 32 is disposed on a circumferential surface of the first planetary gear 26 facing the first sun gear 24 .

[0050] In this way, the end surface friction of the first planetary gear 26 can be reduced, and the first planetary gear 26 can be protected.

[0051] Specifically, the first planetary gears 26 mesh with the first sun gear 24 and the ring gear 30, and revolve between the first sun gear 24 and the ring gear 30. A first friction plate 32 is disposed on the circumferential surface of the first planetary gear 26 facing the first sun gear 24. The first friction plate 32 has excellent friction properties and can withstand and transfer frictional forces, thereby reducing friction between the end surfaces of the first planetary gears 26 and the surface of the base on which the sun gear is mounted, thereby improving transmission efficiency.

[0052] See also Figure 2 In some embodiments, the second planetary gear 36 group includes a second sun gear 34, a second planetary gear 36, and a second planetary carrier 38. The second sun gear 34 is fixedly connected to the first planetary carrier 28, the second planetary gear 36 is externally meshed with the second sun gear 34, the second planetary gear 36 is internally meshed with the ring gear 30, and the second planetary gear 36 is fixedly connected to the second planetary carrier 38.

[0053] In this way, the second planetary gear 36 can reduce and transmit the output speed of the first planetary carrier 28 .

[0054] Specifically, the second sun gear 34 is fixedly connected to the first planet carrier 28, and the second planetary gear 36 is externally meshed with the second sun gear 34 and internally meshed with the ring gear 30. In this way, the second planetary gear 36 rotates under the drive of the second sun gear 34 and revolves between the second sun gear 34 and the ring gear 30. The second planetary gear 36 is fixedly connected to the second planetary carrier 38. The revolution of the second planetary gear 36 drives the second planetary carrier 38 to rotate, and then the second planetary carrier 38 outputs power.

[0055] In some embodiments, the second planetary gear set 36 further includes a second friction plate 40 . The second friction plate 40 is disposed on a circumferential surface of the first planet carrier 28 facing the second planetary gear 36 .

[0056] In this way, friction between the second planetary gear 36 and the first planetary carrier 28 can be reduced, thereby protecting the second planetary gear 36 and the first planetary carrier 28 .

[0057] Specifically, the second planetary gears 36 mesh with the second sun gear 34 and the ring gear 30, and revolve between the second sun gear 34 and the ring gear 30. A second friction plate 40 is disposed between the second planetary gears 36 and the first planet carrier 28. The second friction plate 40 has excellent friction properties and can withstand and transfer frictional forces. This reduces friction between the end faces of the second planetary gears 36 and the surface of the first planet carrier 28 facing the second planetary gears 36, thereby improving transmission efficiency.

[0058] In certain embodiments, the second planetary gear set 36 includes a plurality of second planetary gears 36 , and the plurality of second planetary gears 36 are evenly distributed along the inner circumference of the ring gear 30 .

[0059] In this way, the plurality of second planetary gears 36 can jointly bear the load, making the operation more stable.

[0060] Specifically, the second planetary gear 36 group includes multiple second planetary gears 36, and the multiple second planetary gears 36 are evenly distributed along the inner circumference of the ring gear 30. The load distribution between the multiple second planetary gears 36 is even, that is, the meshing force transmitted by the second sun gear 34 to the multiple second planetary gears 36 is equal, which is beneficial to improving the transmission efficiency of the planetary gear mechanism 18.

[0061] See also Figure 3 In some embodiments, the roller brush includes a brush body 42 and a cleaning member 43. The cleaning member 43 is sleeved on the outer peripheral surface of the brush body 42. An accommodating space is formed inside the brush body 42, and the driving mechanism 12 is at least partially accommodated in the accommodating space.

[0062] In this way, the cleaning effect of the cleaning assembly 10 can be improved.

[0063] Specifically, the roller brush includes a brush body 42 and a cleaning element 43. The cleaning element 43 is sleeved on the outer circumference of the brush body 42. The drive assembly drives the brush body 42 to rotate, which in turn drives the cleaning element 43 to rotate and clean the work surface. A storage space is provided within the brush body 42, and the drive mechanism 12 is at least partially housed within the storage space. This reduces the size of the cleaning element 10, making it suitable for different work scenarios and making it more flexible to move. This allows the roller brush to clean areas such as walls, corners, and crevices, thereby improving cleaning effectiveness.

[0064] Furthermore, the cleaning component 10 is connected to the main body of the cleaning device 100 through the bracket 44, and the driving mechanism 12 is set in the accommodating space inside the brush body 42. The bracket 44 can be connected to the driving mechanism 12 on one side of the brush body 42 or in the middle of the brush body 42. In this way, when cleaning locations such as wall edges and corners, one side or both sides of the roller brush can directly contact the wall edges and corners with zero dead angles, thereby achieving a better cleaning effect.

[0065] See also Figure 3 In some embodiments, the cleaning assembly 10 includes a bracket 44 , the bracket 44 has a mounting hole, and the driving mechanism 12 is rotatably connected to the bracket 44 through the mounting hole.

[0066] In this way, the edge cleaning of the roller brush can be achieved during cleaning.

[0067] Specifically, the cleaning assembly 10 includes a bracket 44, and the driving assembly is accommodated in the accommodating space of the brush body 42. The bracket 44 is respectively connected to the driving mechanism 12 and the main body of the cleaning device 100, so that the main body can drive the cleaning assembly 10 to move and perform cleaning work.

[0068] The bracket 44 defines a mounting hole, and the driving mechanism 12 passes through the mounting hole. A portion of the driving mechanism 12 is rotatably connected to the bracket 44 , and another portion of the driving mechanism 12 is accommodated in the accommodation space of the brush body 42 .

[0069] The bracket 44 is located on one side of the driving assembly at the installation position of the driving assembly, and the other parts of the driving assembly are accommodated in the accommodating space of the brush body 42, so that one side of the roller brush can be cleaned close to the edge.

[0070] See also Figure 3 In some embodiments, the output shaft includes two output ends facing opposite directions, the driving mechanism 12 includes two planetary gear mechanisms 18, a first drive shaft 46 and a second drive shaft 48, the two planetary gear mechanisms 18 are respectively connected to the two output ends, and the two planetary gear mechanisms 18 are respectively connected to the first drive shaft 46 and the second drive shaft 48, the roller brush includes a first roller brush 14a and a second roller brush 14b, the brush body 42 of the first roller brush 14a is connected to the first drive shaft 46, and the brush body 42 of the second roller brush 14b is connected to the second drive shaft 48, and the bracket 44 is arranged between the first roller brush 14a and the second roller brush 14b.

[0071] In this way, when cleaning, both sides of the roller brush can be cleaned along the edges.

[0072] Specifically, the output shaft of the motor 16 includes two output ends arranged in opposite directions, such as Figure 3 The opposite directions shown are left and right directions in the figure. Each output end is connected to a planetary gear mechanism 18 , and the two planetary gear mechanisms 18 are connected to the first drive shaft 46 and the second drive shaft 48 , respectively.

[0073] The bracket 44 and the drive assembly are mounted in the middle of the drive assembly, with the remaining components on either side of the drive assembly accommodated within the space within the brush body 42. The brush bodies 42 of the first and second roller brushes 14a, 14b are connected to a first drive shaft 46, 48, respectively, on either side of the bracket 44. The first drive shaft 46 rotates the brush body 42 of the first roller brush 14a, while the second drive shaft 48 rotates the brush body 42 of the second roller brush 14b. This allows for close-to-edge cleaning of both sides of the roller brushes during cleaning.

[0074] Furthermore, the brush bodies 42 of the first roller brush 14a and the brush bodies 42 of the second roller brush 14b are located on both sides of the bracket 44. If the thickness of the bracket 44 in the axial direction of the brush bodies 42 of the first roller brush 14a and the second roller brush 14b is too large, a gap will be generated at the position of the bracket 44 in the cleaning area on the working surface of the roller brush, and the cleaning member 43 cannot cover it.

[0075] Based on the above problems, the size of the bracket 44 is designed to reduce the thickness of the bracket 44 in the axial direction of the brush body 42 of the first roller brush 14a and the brush body 42 of the second roller brush 14b, and reduce the distance between the brush body 42 of the first roller brush 14a and the brush body 42 of the second roller brush 14b on the side close to the bracket 44, so that the gap generated by the bracket 44 in the cleaning area formed by the roller brush on the working surface is reduced or eliminated.

[0076] In one embodiment, Figure 4 As shown, the outer circumference of the brush body 42 of the first roller brush 14a is sleeved with a first cleaning member 43, and the outer circumference of the brush body 42 of the second roller brush 14b is sleeved with a second cleaning member 43. The gap between the first cleaning member 43 and the second cleaning member 43 at the position of the bracket 44 is 3 mm. Since there are cleaning bristles on the first cleaning member 43 and the second cleaning member 43, a certain pressure is exerted on the roller brush when the cleaning assembly 10 is working, so that the cleaning bristles on both sides of the bracket 44 are expanded to cover the 3 mm gap, so that the cleaning area formed by the roller brush on the working surface is complete without gaps and cleaning dead corners.

[0077] See also Figure 1 and Figure 3 In some embodiments, the length of the first drive shaft 46 is greater than the length of the second drive shaft 48 , and the mounting position of the bracket 44 and the drive mechanism 12 is located on the side where the first drive shaft 46 is located.

[0078] In this way, the volume of the cleaning assembly 10 can be reduced.

[0079] Specifically, when the driving mechanism 12 is installed on the bracket 44, if the motor 16 is located in the middle position of the driving assembly, the first driving shaft 46 and the second driving shaft 48 are symmetrically arranged on both sides of the motor 16, and the bracket 44 is connected to the middle position of the motor 16. The diameter of the mounting hole of the bracket 44 for connecting the driving assembly needs to be larger than the diameter of the motor 16, so that the volume of the roller brush used to accommodate the driving mechanism 12 is larger, which will make the overall volume of the cleaning assembly 10 larger.

[0080] Based on the above problem, the length of the first drive shaft 46 is set to be greater than the length of the second drive shaft 48, so that the motor 16 is offset, and the installation position of the bracket 44 and the drive mechanism 12 is located on the side where the first drive shaft 46 is located. In this way, the diameter of the mounting hole and the volume of the roller brush can be reduced, thereby reducing the overall volume of the cleaning assembly 10.

[0081] In one embodiment, the bracket 44 is connected to the middle position of the motor 16, the diameter of the roller brush is 78 mm, and the installation position of the bracket 44 and the drive mechanism 12 is located on the side where the first drive shaft 46 is located, and the diameter of the roller brush can be reduced to 65 mm.

[0082] See also Figure 2 In some embodiments, the ring gear 30 has a through hole 50, the first drive shaft 46 and the second drive shaft 48 pass through the through hole 50 and are fixedly connected to the second planetary carrier 38 respectively, and the planetary gear mechanism 18 includes a bearing 52, which is installed between the ring gear 30 and the first drive shaft 46 and the ring gear 30 and the second drive shaft 48.

[0083] In this way, the bearing 52 can improve the transmission effect of the first drive shaft 46 and the second drive shaft 48 .

[0084] Specifically, the first drive shaft 46 and the second drive shaft 48 are respectively fixedly connected to the second planetary carrier 38, and are fixedly connected to the brush body 42 through the ring gear 30. The bearing 52 is arranged between the ring gear 30 and the first drive shaft 46 and the second drive shaft 48. The bearing 52 is used to support the first drive shaft 46 and the second drive shaft 48, effectively reducing the mechanical load friction coefficient during the transmission process, thereby improving the overall efficiency of the mechanical equipment.

[0085] At the same time, the bearing 52 can enable the first drive shaft 46 and the second drive shaft 48 to rotate smoothly and with little noise, thereby improving the user experience.

[0086] In summary, the working principle of the planetary gear mechanism 18 is as follows: the motor 16 drives the first sun gear 24 to rotate, the first sun gear 24 is externally meshed with the first planet gear 26, and at the same time the first planet gear 26 is internally meshed with the ring gear 30, the first planet gear 26 rotates to drive the first planet carrier 28 to rotate, the second sun gear 34 is fixedly connected to the first planet carrier 28, the second sun gear 34 is externally meshed with the second planet gear 36, and at the same time the second planet gear 36 is internally meshed with the ring gear 30, the second planet gear 36 rotates to drive the second planet carrier 38 to rotate, and the second planet carrier 38 is fixedly connected to the first output shaft and the second output shaft to realize reduction transmission.

[0087] Bearings 52 are installed on the inner and outer sides of the ring gear 30 to support the rotation of the first output shaft and the second output shaft, and the axial fixation of the first output shaft and the second output shaft is achieved through the gasket 54 and the retaining ring 56; the first friction plate 32 and the second-stage friction plate are used to reduce the end face friction of the first planetary gear 26 and the second planetary gear 36 to improve efficiency.

[0088] When the cleaning component 10 is working, the motor 16 is connected to the planetary gear mechanism 18 respectively. The two ends of the same shaft of the motor 16 drive the two first sun gears 24 to run at the same speed and opposite direction. The corresponding parts of the planetary gear mechanism 18 on both sides run in a mirror-like manner, and the output shaft drives the brush body 42 of the first roller brush 14a and the brush body 42 of the second roller brush 14b to run in the same direction and speed.

[0089] In summary, the planetary gear mechanism 18 reduces the transmission speed and increases the output torque of the second planetary gear set 36 driving the roller brush, preventing the roller brush from getting stuck or stalling during rotation. The motor 16 has two output terminals, enabling both sides of the roller brush to be cleaned close to the edge. The two output shafts of the drive assembly have different lengths, enabling the motor 16 to be offset, effectively reducing the drive assembly's size and making the cleaning assembly 10 more flexible.

[0090] The embodiment of the present invention provides a cleaning device 100, which includes the cleaning component 10 of any of the above embodiments.

[0091] In the above-mentioned cleaning device 100, the output shaft of the motor 16 is driven and reduced through the first planetary gear 26 group and the second planetary gear 36 group to connect and drive the roller brush to rotate. The reduction ratio is increased by the first planetary gear 26 group and the second planetary gear 36 group, thereby increasing the output torque of the roller brush driven by the second planetary gear 36 group, thereby avoiding jamming or stalling of the roller brush during rotation.

[0092] Specifically, the cleaning device 100 includes but is not limited to a floor cleaning machine, a vacuum cleaner, a sweeping robot or other devices with a cleaning function.

[0093] It should be noted that the above explanations of the implementation and beneficial effects of the cleaning component 10 are also applicable to the cleaning device 100 of the embodiment of the present invention, and will not be elaborated here in detail to avoid redundancy.
