Background

The cleaning apparatus generally comprises a cleaning head, such as a floor brush, comprising a motor, a gear reduction box and a roller brush assembly connected in sequence, the roller brush assembly being driven by the motor assembly and rotated after reduction by the gear reduction box.

That is, for the side edge of the rolling brush component, which is close to the gear reduction box, the projection position of the gear reduction box on the ground can not be cleaned by the rolling brush component due to the blocking of the gear reduction box, so that a cleaning dead angle is formed.

The prior proposal realizes bilateral cleaning by arranging the motor and the transmission component in the middle, arranging the rolling brush component on the two sides of the axial direction of the motor and the transmission component, or arranging the motor in the rolling brush component.

The application provides a cleaning device and a driving device, which are described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Referring to fig. 1, the present embodiment provides a cleaning apparatus 10, where the cleaning apparatus 10 may be a hand-held cleaner, a floor scrubber, a carpet extractor, a tabletop cleaner, a cleaning robot, or other cleaning device, and the present embodiment is not limited thereto. Here, the cleaning apparatus 10 includes a driving member 100, a transmission assembly 200, and a rolling brush assembly 300.

Here, the roller brush assembly 300 has an axis a, which in the embodiments of the present application is referred to axially, radially and circumferentially. Wherein the axial direction refers to the extending direction of the axis a, the radial direction refers to the direction perpendicular to the axis a, and the circumferential direction refers to the direction along a circumferential line extending concentrically around the axis a.

Here, the cleaning apparatus 10 includes a housing, and with continued reference to fig. 1, the housing includes a first housing 410, a second housing 420, and a cover 430. Wherein the first housing 410 and the second housing 420 are matched with each other and enclose an inner cavity 440, the driving member 100, the transmission assembly 200 and the rolling brush assembly 300 may be disposed in the inner cavity 440. In the illustrated orientation of fig. 1, the first housing 410 is an upper housing and the second housing 420 is a lower housing. The upper case is provided with the cover 430 at a position corresponding to the rolling brush assembly 300, and when the cover 430 is detached, the receiving position of the rolling brush assembly 300 is exposed to facilitate the installation and detachment of the rolling brush assembly 300, and when the cover 430 is installed on the upper case, the rolling brush assembly 300 is shielded to help to protect the rolling brush assembly 300 and other components within the inner cavity 440. The lower side of the lower case is generally further provided with a hollowed-out portion (not shown) corresponding to the position of the rolling brush assembly 300, and the rolling brush assembly 300 is exposed downwards through the hollowed-out portion and can clean the surface to be cleaned. Of course, in other embodiments, the cleaning apparatus 10 may have no housing or the housing is not limited to the above, and the present embodiment is not limited thereto.

The driving member 100 is configured to provide a driving force for driving the rolling brush assembly 300 to move, wherein, in general, the driving member 100 is disposed in a housing, which may be a motor, and the motor is disposed generally parallel to the axis a, that is, an axial direction of the motor is parallel to an extending direction of the axis a so as to form a transmission connection with the rolling brush assembly 300. Referring to fig. 2 and 3, the cleaning apparatus 10 further includes a support member 500, the support member 500 being disposed in the housing, and the driving member 100 being mounted on the support member 500, such that the driving member 100 can be maintained in a desired mounted position.

The motor may drive the rolling brush assembly 300 to rotate when in operation. However, the rotational speed of the motor is generally too high to provide a suitable torque to the rolling brush assembly 300, and thus a transmission assembly 200 is required to be provided at the output end of the driving member 100, and the driving member 100 is in transmission connection with the rolling brush assembly 300 through the transmission assembly 200, and the transmission assembly 200 is used for reducing the rotational speed to increase the torque of the rolling brush assembly 300.

For this reason, in the embodiment of the present application, referring to fig. 3, the transmission assembly 200 includes a first reduction mechanism 210 and a second reduction mechanism 220 that are sequentially connected, and the rotational speed and torque of the rolling brush assembly 300 can be better adjusted to be within a desired range by providing a two-stage reduction mechanism.

Herein, referring to fig. 2, the first speed reducing mechanism 210 is a V-belt speed reducing structure, and includes a first pulley 211, a second pulley 212, and a V-belt 213, wherein the V-belt 213 is wound on the first pulley 211 and the second pulley 212 to realize a transmission connection therebetween. Wherein the radius of the first pulley 211 is smaller than that of the second pulley 212, the first pulley 211 is connected to the output shaft of the driving member 100 in a torsion-proof manner and can rotate along with the rotation of the output shaft of the driving member 100, the second pulley 212 is connected to the first pulley 211 through the V belt 213 in a transmission manner, and the first pulley 211 can rotate while driving the second pulley 212.

The transmission ratio of the V belt 213 is in the range of 1:1-1:6, the circumference of the V belt is in the range of 160mm-250mm, and the width of the V belt 213 is not more than 5mm. With this arrangement, the V-belt 213 is smaller in dimension in the axial direction (i.e., its width) so that the roller brush can be set longer to achieve a better cleaning effect. Illustratively, the V-belt 213 has a gear ratio of 1:3, a circumference of 214mm and a width of 4mm. Also exemplary, the V-belt 213 has a gear ratio of 1:6, a circumference of 250mm and a width of 5mm. Still further exemplary, the V-belt 213 has a gear ratio of 1:1.1, a circumference of 160mm and a width of 4mm. In yet another example, the V-belt 213 has a gear ratio of 1:1.1, a circumference of 200mm and a width of 5mm. Of course, the above examples do not show all values of the V-band related parameters, and the examples do not unduly limit the present application. And it is understood that the V-belt 213 may be sized to satisfy at least one of a gear ratio range of 1:1 to 1:6, a circumference range of 160mm to 250mm, and a width of not more than 5mm, which is not unduly limited by the example of the present embodiment.

Here, in the speed reduction mechanism applied to the cleaning apparatus 10, a synchronous belt speed reduction structure is generally used instead of a V-belt speed reduction structure, since the speed reduction mechanism of the cleaning apparatus 10 is generally single-stage speed reduction, which results in a large speed reduction ratio, and in the case of a large speed reduction ratio, the V-belt 213 generates a large amount of heat, which is disadvantageous for the use of the cleaning apparatus 10. Accordingly, in the cleaning apparatus 10, it is conventional in the art to employ a synchronous belt reduction structure to achieve a drive connection between the motor and the roller brush assembly 300. However, here, the inventors of the present application have found that the heating value of the V-belt 213 has been reduced considerably when two-stage deceleration is applied, without any significant adverse effect on the use of the cleaning apparatus 10. In particular, in the present application, if the synchronous belt speed reducing mechanism is adopted and the size of the synchronous belt is set to be similar to the size of the V belt 213, the toothed structure of the inner periphery of the synchronous belt is easily worn, and the service life and stability thereof are poor. Accordingly, in some embodiments of the present application, the first reduction mechanism 210 employs the V-belt reduction structure described above, which can provide better transmission stability and longer service life.

Of course, it should be understood that, in other embodiments, the first speed reducing mechanism 210 may be a synchronous belt speed reducing structure, a sprocket speed reducing structure, etc., and the present embodiment is not limited thereto, for example, in applications with lower transmission accuracy and stability, such as the cleaning apparatus 10 for home use, the cleaning apparatus may be a relatively flat bottom surface, and a synchronous belt speed reducing structure may be used as the first speed reducing mechanism 210, where the synchronous belt speed reducing structure has an advantage of low cost. But compared with a synchronous belt speed reducing structure and the like, when the V belt speed reducing structure provided by the embodiment of the application is adopted, the V belt speed reducing structure can achieve the better technical effects of higher transmission stability and longer service life while the width is shorter (namely, the size in the axial direction of the rolling brush assembly 300 is shorter).

Here, referring to fig. 5, in some embodiments, the support 500 is located on a side of the rolling brush assembly 300 near the first reduction mechanism 210 and the second reduction mechanism 220, and the support 500 is connected to the housing of the cleaning apparatus, and the first pulley 211 and the second pulley 212 of the first reduction mechanism 210 are located in the support 500. Here, the length of the rolling brush assembly 300 along the axial direction is L3, and the length of the supporting member 500 and the housing of the cleaning apparatus 10 along the axial direction outside the rolling brush assembly 300 is L5, L3: the value of (l3+l5) is 95% or more so that the roller brush assembly 300 can be disposed long in the axial direction within the housing of the cleaning apparatus 10 to reduce the dead angle of cleaning of the side edge portions. Illustratively, L3 has a length of 250mm, L5 has a length of 11.4mm, L3: the value of (L3+L5) was 95.6%.

Herein, referring to fig. 3, the second reduction mechanism 220 is a planetary gear reduction structure, and includes a central input shaft 221, a planetary gear set 222, an inner gear ring 223, and a planet carrier 224.

Referring to fig. 4, the center input shaft 221 is connected to the second pulley 212 in a torsion-proof manner, wherein the center input shaft 221 is connected to the second pulley 212 by a screw, and an axis of the center input shaft 221 passes through a center of the second pulley 212, and the center input shaft 221 is disposed coaxially with the axis a. While the second pulley 212 rotates to synchronously rotate the central input shaft 221, it will be understood that, in other embodiments, the specific connection between the central input shaft 221 and the second pulley 212 may be different, for example, the central input shaft 221 may be integrally formed with the second pulley 212, etc., which is not limited in this embodiment.

An external gear is provided on the central input shaft 221, and meshes with a planetary gear set 222. Illustratively, the planetary gear set 222 includes three planetary driven wheels (not shown) that are uniformly disposed circumferentially about a straight line along which the central input shaft 221 is located, and are engaged with the central input shaft 221 at a central position, so that the central input shaft 221 rotates to drive the three planetary driven wheels to rotate. It will be appreciated that in other embodiments, four or more planetary driven wheels may be employed for the planetary gear set 222, and the present example is not limited thereto.

Further, the planetary gear set 222 is engaged with the ring gear 223, and in the example in which three planetary driven gears are provided, that is, three planetary driven gears are engaged with the radial inner side of the ring gear 223, the planetary driven gears can rotate in the ring gear 223, and the ring gear 223 and the central input shaft 221 are engaged with both the inner and outer sides of the planetary gear set 222, respectively, so that the planetary gear set 222 can perform revolution and rotation stably.

Meanwhile, the planetary gear set 222 is disposed on the planet carrier 224, a connection shaft 2242 (refer to fig. 3) is disposed on the planet carrier 224 corresponding to the planetary driven wheel of the planetary gear set 222, the connection shaft 2242 is used for connecting the planetary driven wheel, and the planetary driven wheel of the planetary gear set 222 can drive the planet carrier 224 to rotate when revolving about the axis a. And, the planet carrier 224 has a planet carrier output shaft 2241, and the planet carrier output shaft 2241 is connected to the rolling brush assembly 300 through a connecting shaft 2242, so that the planet gear set 222 rotates to drive the planet carrier 224 to rotate, thereby transmitting power to the rolling brush assembly 300 through the planet carrier output shaft 2241 of the planet carrier 224, and driving the rolling brush assembly 300 to rotate along the circumferential direction of the axis a.

Here, in some embodiments, to protect the components, the second transmission mechanism further includes a housing 225, and the housing 225 may be connected to the support 500, and thus the support 500 may hold the second transmission mechanism in a desired position. The center input shaft 221, the planetary gear set 222, the ring gear 223, and the planet carrier 224 are disposed in the housing 225, the center input shaft 221 extends from inside the housing 225 toward the outside near the second pulley 212, and the planet carrier output shaft 2241 of the planet carrier 224 extends from inside the housing 225 toward the outside near the rolling brush assembly 300. Also, a bearing 226 or the like may be provided between the radially outer side of the carrier output shaft 2241 and the radially inner side of the housing 225 with respect to the portion of the carrier output shaft 2241 located in the housing 225, and similarly, a bearing may be provided between the radially outer side of the center input shaft 221 and the radially inner side of the housing 225 with respect to the portion of the center input shaft 221 located in the housing 225, which is not limited in this embodiment. In addition, in order to meet the requirements of assembly precision and the like, structures such as a gasket and a snap spring may be further provided in the second transmission mechanism, which is not limited in this embodiment.

While the planetary gear reduction structure is illustrated above, it will be understood by those skilled in the art that various components of the planetary gear reduction structure may be modified and the reduction transmission function may be implemented as well, only the second reduction mechanism 220 is in transmission connection with the first reduction mechanism 210, and the second reduction mechanism 220 has an output end for outputting power to the rolling brush assembly 300, which is not an undue limitation on the specific components and connection structure of the planetary gear reduction structure in the present application.

For example, in other embodiments, please refer to fig. 6-9, which illustrate the second reduction mechanism 220 and its connection relationship with other components. Here, the second reduction mechanism 220 is substantially the same as the second reduction mechanism 220 shown in fig. 1 to 5. Except that, herein, please refer to fig. 7, the second reduction mechanism 220 further includes a transmission connection 227 and a stabilizing bearing 228. The transmission connection member 227 is disposed on the support member 500 and extends in a direction approaching the rolling brush assembly 300 in the axial direction, wherein the transmission connection member 227 is disposed coaxially with the axis a, that is, the transmission connection member 227 is centered on the axis a. Referring to fig. 8, the stabilizing bearing 228 is disposed on the radial outer side of the supporting member 500, and the stabilizing bearing 228 includes a bearing portion and an additional portion disposed on the circumferential side of the bearing portion, and the stabilizing bearing 228 may be an over-molded bearing, and the additional portion is made of nylon PA, polyoxymethylene POM, engineering plastic polypropylene, or the like. Here, since the rolling brush assembly 300 contacts with the external object when rotating, the rolling brush assembly 300 may vibrate, and the vibration may vibrate the second reduction mechanism 220 in driving engagement with the rolling brush assembly, and cause the central axis line of the central input shaft 221 and the planet carrier output shaft 2241 of the second reduction mechanism 220 to deviate from the axis line a, so that the stability of the operation of the planetary gear set 222 engaged with the central input shaft 221 and the planet carrier output shaft 2241 may be reduced. In the example shown in fig. 6 to 9, the central axis of the housing 225 is maintained at a position not deviating from the axis a by the transmission connection 227 coaxially disposed with the axis a, and thus, the components such as the central input shaft 221, the planetary gear set 222, and the carrier output shaft 2241 in the housing 225 may be limited so as to maintain the components at predetermined positions. The stabilizing bearing 228 may be provided to support the driving connection 227, which may help to ensure stability of the driving connection 227, although in some embodiments, the stabilizing bearing 228 may not be provided, and this embodiment is not limited thereto. The arrangement makes the transmission fit of the second reduction mechanism 220 more stable, and the transmission stability of the second reduction mechanism 220 is not easily affected by external force. The transmission connection member 227 may be an integral structure, or may be a structure formed by connecting multiple components, for example, it includes a first portion connected to the housing 225 and a second portion connected to the support member 500, where the first portion and the second portion are connected by a bolt, welding, clamping, or other manner, and the present embodiment is not limited thereto.

With reference to fig. 1 in conjunction with fig. 5, the cleaning apparatus 10 further includes a rolling brush assembly 300, and the rolling brush assembly 300 is disposed at an output end of the second reduction mechanism 220. Here, the roll brush assembly 300 illustratively includes a base body, which is generally cylindrical, and roll brush strips and/or bristles (not shown) disposed on the base body, which are disposed on an outer surface of the base body. With continued reference to fig. 5, the base body is provided with a receiving space 320 at an inner side in an axial direction, and the receiving space 320 extends along the axial direction and penetrates through an end of the base body near the second reduction mechanism 220 to form an opening 310 (please refer to fig. 1) at an end of the base body near the second reduction mechanism 220, wherein the opening 310 is used for at least part of the second reduction mechanism 220 to extend into the receiving space 320. Illustratively, the planet carrier output shaft 2241 of the planetary gear reduction structure extends 310 into the receiving space 320 through the opening and is connected to the base body.

Here, as shown in fig. 5, the length L2 of the second reduction mechanism 220 in the axial direction is shorter than the length L1 of the driving member 100 in the axial direction, i.e., the free end of the driving member 100 in the axial direction is farther from the first reduction mechanism 210 than the free end of the second reduction mechanism 220. Specifically, the length L1 of the driving member 100 in the axial direction includes the length of the output shaft of the driving member, and the length L2 of the second reduction mechanism 220 in the axial direction includes the length of the output shaft thereof. Accordingly, here, the length of the accommodation space for accommodating the second reduction mechanism 220 in the axial direction may also be shorter than the length L1 of the driving member 100 in the axial direction. Of course, it is understood that in other embodiments, the length of the accommodating space in the axial direction may be longer than the length L1 of the driving member 100 in the axial direction.

Here, at least part of the second reduction mechanism 220 is located in the accommodating space, and the remaining part is located axially outside the rolling brush assembly 300. The more the second reduction mechanism 220 is located in the accommodating space, the smaller the occupied space of the second reduction mechanism 220 outside the rolling brush assembly 300 is, the longer the axial length of the rolling brush assembly 300 can be set in the housing, so that the cleaning dead angle of the rolling brush assembly 300 is less, and the cleaning effect of the rolling brush assembly 300 is better. For example, when the second reduction mechanism 220 is entirely located in the accommodating space, only the carrier and the first reduction mechanism 210 are located outside the accommodating space in the axial direction, so that the substrate of the rolling brush assembly 300 may be disposed longer in the axial direction, only the projection of the axial area occupied by the carrier and the second pulley 212 of the first reduction mechanism 210 on the surface to be cleaned may not be cleaned, and the cleaning dead angle of the rolling brush assembly 300 may be reduced.

However, it will be appreciated that since the periphery of the roller brush assembly 300 is provided with a housing, displacement of the roller brush assembly 300 in the axial direction is limited at the time of mounting and dismounting. If the axial dimension of the portion of the second reduction mechanism 220 extending into the accommodating space of the rolling brush assembly 300 is too long, the operation of extending the second reduction mechanism 220 into the rolling brush assembly 300 and connecting the rolling brush assembly 300 and removing the rolling brush assembly 300 from the second reduction mechanism 220 is inconvenient.

Here, the length L2 of the second reduction mechanism 220 in the axial direction is set shorter, so that the second reduction mechanism 220 occupies less space in the axial direction. In this way, when the second reduction mechanism 220 is extended into the rolling brush assembly 300, it contributes to making the axial dimension of the extended portion thereof small while being able to ensure that the axial dimension of the portion thereof located axially outside the rolling brush assembly 300 is also small. Illustratively, when the second reduction mechanism 220 is fully inserted into the accommodating space 320 of the rolling brush assembly 300, the installation and removal of the rolling brush assembly 300 is still not significantly affected due to the smaller axial dimension. Thus, through the above-mentioned setting, can make the longer in order to reduce clean dead angle and realize better clean effect that the round brush can set up, simultaneously, also guaranteed the convenience when the round brush subassembly 300 is installed and is dismantled. Of course, in other embodiments, a portion of the axial side of the second reduction mechanism 220 away from the rolling brush assembly 300 may be located outside the accommodating space 320, and since a portion of the second reduction mechanism 220 is already accommodated in the accommodating space 320 and the axial length of the second reduction mechanism 220 is smaller, the axial length of the second reduction mechanism 220 remaining outside the accommodating space 320 will also be smaller, which helps to reduce the influence on the rolling brush length and reduce the dead cleaning angle of the cleaning apparatus 10.

Illustratively, in some embodiments, the length of the portion of the second reduction mechanism 220 axially located in the accommodating space 320 is LX, and then the length of the portion of the second reduction mechanism 220 axially located outside the accommodating space 320 is L2-LX, the length of the rolling brush assembly 300 axially is L3, and LX is less than or equal to 2/5 of L3.

Here, as described above, in some embodiments, the second reduction mechanism 220 is connected to the rolling brush assembly 300 through the coupling 600, and thus, the length L4 in the axial direction of the second reduction mechanism 220 after being connected to the coupling 600 may also affect the cleaning effect and the installation convenience of the rolling brush assembly 300. Therefore, in these embodiments, the length L4 in the axial direction after the second reduction mechanism 220 is connected to the coupling 600 is set to be shorter than the length L1 in the axial direction of the driving member 100.

In some embodiments, the length of the accommodating space 320 is L4 in the axial direction, the length of the rolling brush assembly 300 is L3, the range of L3/L4 is 1/4-1/2, and the length range L3 of the rolling brush assembly 300 is 240-260mm, and the length L4 of the accommodating space 320 is not less than 70mm. Thereby facilitating installation of the roll brush assembly 300 into the receiving space 320. Illustratively, the value of L3/L4 is 1/4; also illustratively, L3/L4 has a value of 1/2; still further exemplary, the value of L3/L4 is 1/3. In some embodiments, the length L4 of the second reduction mechanism 220 in the axial direction after being connected to the coupling 600 is shorter than 100mm. Here, the length of the rolling brush assembly 300 in the axial direction is set between 235mm and 250mm, for example. In some embodiments, referring to fig. 1, the cleaning apparatus 10 further includes a dust suction opening 700, where the dust suction opening 700 is disposed on a radial side of the rolling brush assembly 300, and is generally disposed in a middle area of the floor brush, and where the dust suction opening 700 is generally disposed on a rear side of the rolling brush assembly 300 with respect to a direction in which the cleaning apparatus 10 moves during operation (referring to fig. 3), although the present embodiment is not limited thereto, and the dust suction opening 700 may be disposed in other positions of the rolling brush assembly 300. And, the dust collection opening 700 is connected to the inner cavity 440, and the dust collection opening 700 is connected to a dust collection component (not shown) of the cleaning apparatus 10 through a suction channel (not shown), and the dust collection component may be a dust bucket, a dust bag, etc. A suction source, which may be a pump or the like, is arranged in the suction channel to create a suction pressure. In use, the dust and other foreign matters lifted by the rolling brush assembly 300 are sucked into the dust collection assembly through the dust suction port 700 and the suction passage under the action of the suction pressure.

Here, if the second reduction mechanism 220 or the coupling 600 is extended to a position located at the front side of the cleaner, the dust is easily contaminated on the second reduction mechanism 220 and/or the coupling 600 due to the fact that the assembly seal is not completely achieved, which reduces the cleanliness of the second reduction mechanism 220 and/or the coupling 600, and may affect the mating connection between the components due to the invasion of the dust, thereby affecting the stability of the transmission. Meanwhile, since the second reduction mechanism 220 and/or the coupling 600 are generally fixedly disposed within the housing of the cleaning apparatus 10, it is also inconvenient to disassemble and clean.

To this end, in some embodiments, the end of the second reduction mechanism 220 extending into the accommodating space does not axially exceed the position of the dust collection opening 700, i.e. the dust collection opening 700 is exposed, so that the roller brush assembly is disassembled to remove the contaminants accumulated in the dust collection opening 700. Illustratively, when the second reduction mechanism 220 is coupled to the roller brush assembly 300 via the coupling 600, the end of the coupling 600 remote from the planet carrier output shaft 2241 is located at a position not exceeding the dust collection port 700 in the axial direction.

In some embodiments, referring to fig. 4, the housing 225 is connected to the support 500, and the housing 225 and the support 500 overlap each other at least partially in the axial direction, i.e., the housing 225 and the support 500 overlap each other in the Z-section of fig. 4. Here, a portion of the housing 225 is disposed radially outside the supporter 500, and the overlapping arrangement of the two in the axial direction makes the housing 225 and the supporter 500 be smaller in the axial direction after being coupled while ensuring structural strength, sealability, etc., so that the rolling brush assembly 300 can be disposed longer and thus have a better cleaning effect.

In other embodiments, referring to fig. 8, the housing 225 is coupled to the drive connection 227, and the housing 225 and the drive connection 227 axially overlap each other at least partially, i.e., the housing 225 and the drive connection 227 overlap each other in the portion Y of fig. 8. Here, a portion of the housing 225 is disposed radially outside the driving connection member 227, and the overlapping arrangement of the two in the axial direction makes the housing 225 and the driving connection member 227 have a smaller size in the axial direction after being connected while ensuring structural strength, sealing property, etc., so that the rolling brush assembly 300 can be disposed longer and thus have a better cleaning effect.

Accordingly, the embodiment of the present application further provides a driving device for the rolling brush assembly 300 to drive the rolling brush assembly 300 to rotate, which includes the driving member 100 and the transmission assembly 200, wherein the driving member 100 has an axial direction, and the axial direction of the driving member is parallel to the axial direction of the rolling brush assembly 300.

Wherein the length of the second reduction mechanism 220 in the axial direction is shorter than the length of the driving member 100 in the axial direction.

In some embodiments, the first reduction mechanism 210 includes a first pulley 211, a second pulley 212, and a V-belt 213, the V-belt 213 being disposed on the first pulley 211 and the second pulley 212.

In some embodiments, the driving device is further provided with a coupling 600, the second reduction mechanism 220 is a planetary gear reduction structure and has a planet carrier output shaft 2241, the coupling 600 connects the planet carrier output shaft 2241 with the rolling brush assembly 300, and the length of the second reduction mechanism 220 after being connected with the coupling 600 is shorter than the length of the driving member 100 along the axial direction.

In some embodiments, the second reduction mechanism is less than 100mm in length in the axial direction after being connected to the coupling.

In some embodiments, the length of the portion of the second reduction mechanism 220 located in the accommodating space along the axial direction is LX, the length of the rolling brush assembly 300 along the axial direction is L3, and LX is less than or equal to 2/5 of L3.

In some embodiments, the driving apparatus further comprises a support 500, and the second reduction mechanism 220 and the driving member 100 are connected to the support 500; the second reduction mechanism 220 further includes a housing 225, the housing 225 is connected to the support 500, and the housing 225 and the support 500 are at least partially overlapped with each other in the axial direction.

In some embodiments, the length of the rolling brush assembly 300 along the axial direction is L3, and on the side of the rolling brush assembly 300 near the transmission assembly 200, the length of the supporting member 500 and the housing of the cleaning device along the axial direction outside the rolling brush assembly 300 is L5, L3: the value of (L3+L5) is 95% or more.

Accordingly, the embodiment of the application further provides a cleaning device 10, where the cleaning device 10 includes a floor brush, the floor brush includes a driving member 100, a transmission assembly 200, and a rolling brush assembly 300, and the transmission assembly 200 is disposed at an output end of the driving member 100 and includes a first speed reducing mechanism 210 and a second speed reducing mechanism 220 that are sequentially connected. The rolling brush assembly 300 is disposed at the output end of the second reduction mechanism 220, where the rolling brush assembly 300 has an axial direction and an accommodating space 320 on the inner side, and the accommodating space 320 extends along the axial direction and has an opening toward the side of the second reduction mechanism 220.

Wherein at least part of the second reduction mechanism 220 is located in the accommodating space 320, and the length of the second reduction mechanism 220 along the axial direction is shorter than the length of the driving member 100.

In some embodiments, at least a portion of the second reduction mechanism 220 is located in the accommodating space 320, the length of the rolling brush assembly 300 along the axial direction is L3, and on the side of the rolling brush assembly 300 near the transmission assembly 200, the length of the supporting member 500 and the housing along the axial direction located outside the rolling brush assembly 300 is L5, where L3: the value of (L3+L5) is 90% or more.

Here, the length L3 of the rolling brush assembly 300 along the axial direction is relatively long, and the length L5 of the supporting member 500 and the housing along the axial direction located outside the rolling brush assembly 300 is relatively short, so that the rolling brush assembly 300 can clean the surface to be cleaned better, and the cleaning dead angle on the side close to the transmission assembly 200 is smaller. Wherein generally the length of the roll brush assembly 300 may be set between 235mm-250mm, in a preferred embodiment the length of the roll brush assembly 300 along the axial direction may be set at 250mm.
