[0058] In the related art, the cleaning parts of the cleaning equipment achieve cleaning by self-rotation, and the entire housing of the cleaning equipment is mostly circular. However, there are blind spots for cleaning during operation, resulting in a limited cleaning range and poor cleaning effect.

[0059] In view of this, the present application provides a cleaning device, which can be used for cleaning equipment. Exemplarily, the outer shell structure of the cleaning equipment is disc-shaped, and the cleaning device is installed on the outer shell of the cleaning equipment.

[0060] A cleaning assembly can be provided on the cleaning device to clean the work surface, and the cleaning assembly is fixed on the support body of the cleaning device. The cleaning assembly may include a cleaning member and an output rod. The cleaning member may be, for example, a mop. The cleaning member is mounted on the output rod, and the rotating mechanism drives the output rod to drive the cleaning member to rotate. In order to reduce the leakage of cleaning blind spots, the cleaning assembly in the embodiment of the present application is divided into a first cleaning assembly and a second cleaning assembly, wherein the first cleaning assembly can swing relative to the support body, thereby expanding the cleaning range and improving the cleaning effect. The second cleaning assembly cannot swing relative to the support body. The cleaning device may only have the first cleaning assembly, or may include the first cleaning assembly and the second cleaning assembly at the same time. The number of the first cleaning assembly and the number of the second cleaning assembly are not limited, and may be one, two or more respectively.

[0061] See also Figures 1-4 The cleaning device 100 includes a support body 10 , a first cleaning assembly 20 , a second cleaning assembly 60 , a rotating mechanism 30 and a swinging mechanism 40 .

[0062] The support body 10 is generally shell-shaped and includes a housing for mounting the first cleaning assembly 20, the second cleaning assembly 60, the rotating mechanism 30, and the swing mechanism 40. The support body 10 includes a first support body 11 and a second support body 12. The first support body 11 is used to mount the second cleaning assembly 60, as well as a portion of the swing mechanism 40 and the rotating mechanism 30; the second support body 12 is used to mount the first cleaning assembly 20, as well as other portions of the swing mechanism 40 and the rotating mechanism 30. The first cleaning assembly 20 includes a first cleaning member 21 and a first output rod 22. The first cleaning member 21 is disposed at one end of the first output rod 22, for example, detachably connected to one end of the first output rod 22, and the other end of the first output rod 22 is inserted through the second support body 12. The second cleaning assembly 60 includes a second cleaning member 61 and a second output rod 62. The second cleaning member 61 is disposed at one end of the second output rod 62, for example, detachably connected to one end of the second output rod 62, and the other end of the second output rod 62 is inserted through the first support body 11.

[0063] The rotating mechanism 30 is used to drive the first cleaning assembly 20 and the second cleaning assembly 60 to rotate for cleaning. The rotating mechanism 30 includes a rotating drive member 31 and a rotating transmission member 32. The rotating drive member 31 is used to provide power for the first cleaning assembly 20 and the second cleaning assembly 60 to rotate; the rotating transmission member 32 is used to transmit the power of the rotating drive member 31 to the first cleaning assembly 20 and the second cleaning assembly 60. The rotating drive member 31 is disposed on the first support body 11 and is drivingly connected to the rotating transmission member 32. The rotating transmission member 32 is drivingly connected to the first output rod 22 and the second output rod 62, respectively, so that the first output rod 22 drives the first cleaning assembly 21 to rotate, and the second output rod 62 drives the second cleaning assembly 61 to rotate. Under the action of the rotating mechanism 30, both the first cleaning assembly 20 and the second cleaning assembly 60 can rotate to perform cleaning operations.

[0064] For example, the rotary drive member 31 may include a drive motor, such as an AC motor or a DC motor. The rotary transmission member 32 may be driven in any manner, for example, by gears, belts, or chains.

[0065] The swing mechanism 40 includes a switching shaft 41 , a swing driving member 42 and a swing transmission member 43 . Figure 3The dotted line shows the change in position of the first cleaning assembly 20 and the second support body 12 after the swing. An adapter shaft 41 is provided through the first support body 11 and the second support body 12. A swing drive member 42 is drivably connected to a swing transmission member 43, so that the second support body 12 drives the first cleaning assembly 20 to swing relative to the first support body 11 about the adapter shaft 41. The swing drive member 42 is used to provide power to swing the first cleaning assembly 20 relative to the adapter shaft 41. The swing drive member 42 can be provided on the first support body 11 or the second support body 12. Illustratively, the swing drive member 42 can include a drive motor, such as an AC motor or a DC motor. The swing transmission member 43 is used to transmit the power of the swing drive member 42 first to the second support body 12, and then to the first cleaning assembly 20 through the second support body 12, enabling the first cleaning assembly 20 to rotate relative to the first support body 11 about the adapter shaft 41 as the rotation center, so that the first cleaning assembly 20 and the second support body 12 can swing together relative to the first support body 11. There is no limitation on the way of realizing transmission by the swinging rotating member. For example, the rotating transmission member 32 can adopt gear transmission, belt transmission, chain transmission, elastic member or electric cylinder, or a combination of the above methods.

[0066] See also Figure 4 The driving force of the rotary driving member 31 is first transmitted to the adapter shaft 41 through the rotary transmission member 32, and then transmitted to the first cleaning component 20 by the adapter shaft 41 through the rotary transmission member 32; at the same time, the driving force of the rotary driving member 31 is transmitted to the second cleaning component 60 through the rotary transmission member 32.

[0067] In this embodiment, the provision of a swing mechanism 40 expands the range of motion of the first cleaning assembly 20, thereby increasing the cleaning area of ​​the first cleaning assembly 20 and improving cleaning effectiveness. The swing mechanism 40 allows the first cleaning assembly 20 to swing relative to the first support 11. For example, if the cleaning device's housing is disc-shaped, corners that cannot be cleaned during cleaning can be swung out of the housing to allow cleaning.

[0068] For some examples, see Figure 5 and Figure 6 The swing driving member 42 is arranged on the first support body 11, and the swing transmission member 43 includes a first elastic member 431. The first elastic member 431 is connected to the second support body 12, and the swing driving member 42 is drivingly connected to the first elastic member 431.

[0069] The first elastic member 431 is used to provide power to the second support body 12 to swing relative to the adapter shaft 41. Under the action of the swing drive member 42, the first elastic member 431 drives the second support body 12 to rotate, and then drives the first cleaning component 20 to rotate, so that the first cleaning component 20 and the second support body 12 can swing relative to the first support body 11, thereby expanding the cleaning range and improving the cleaning effect. At the same time, the first elastic member 431 can undergo elastic deformation to obtain elastic potential energy. When the first cleaning component 20 rotates and encounters an obstacle, the first elastic member 431 can release the elastic potential energy, causing the first cleaning component 20 to passively retract. In this way, the first elastic member 431 can play a role in buffering and vibration reduction, reducing the possibility of damage to the first output rod 22 or the first cleaning member 21 when encountering obstacles or collisions.

[0070] For some examples, see Figure 5 and Figure 6 The swinging transmission member 43 also includes a first transmission wheel group 432 and a sleeve 433. The sleeve 433 is sleeved on the adapter shaft 41. The two ends of the first elastic member 431 are respectively connected to the sleeve 433 and the second support body 12. The swinging driving member 42 is driven and connected to the first transmission wheel group 432. The first transmission wheel group 432 and the sleeve 433 are driven and connected.

[0071] In this way, the driving force of the swing drive member 42 is first transmitted to the first transmission wheel assembly 432, which in turn drives the sleeve 433 to rotate. The first transmission wheel assembly 432 can adjust the transmission ratio of the swing mechanism 40, thereby adjusting the swing speed of the second support body 12, so that the swinging process is more stable. One end of the first elastic member 431 is fixed to the sleeve 433, and the other end is fixed to the second support body 12. Under the action of the swing drive member 42, the first transmission wheel assembly 432 rotates, which in turn drives the sleeve 433 to rotate, causing the first elastic member 431 to elastically deform, thereby driving the second support body 12 to rotate, and then driving the first cleaning assembly 20 to swing.

[0072] For some examples, see Figure 5 and Figure 6 The second support body 12 is formed with a convex cylinder 121. The first transmission wheel assembly 432 includes a first transmission wheel 4321 and a second transmission wheel 4322 that are engaged with each other. The swing driving member 42 is drivingly connected to the first transmission wheel 4321. The second transmission wheel 4322 is fixed to a sleeve 433. The sleeve 433 is sleeved on the convex cylinder 121. The first elastic member 431 is located between the sleeve 433 and the convex cylinder 121. Exemplarily, the first elastic member 431 is a torsion spring.

[0073] The second support body 12 is formed with a convex cylinder 121, which facilitates the installation of a torsion spring. One end of the torsion spring is fixed to the sleeve 433, and the other end is fixed to the convex cylinder 121, allowing the torsion spring to apply torque to the convex cylinder 121. The torsion spring, sleeve 433, and second transmission wheel 4322 are sequentially mounted on the adapter shaft 41. Under the action of the swing drive member 42, when the first and second transmission wheels 4321 and 4322 rotate, the sleeve 433 causes the torsion spring to elastically deform, which in turn drives the convex cylinder 121 to rotate, causing the first cleaning assembly 20 to swing.

[0074] Exemplarily, the swing driving member 42 has a transmission wheel that meshes with the first transmission wheel 4321 for transmission.

[0075] Exemplarily, the second transmission wheel 4322 and the sleeve 433 are interference fit. In other embodiments, the sleeve 433 has a keyway on its surface, and the sleeve 433 and the second transmission wheel 4322 are key-driven.

[0076] For example, both the sleeve 433 and the convex cylinder 121 have fixing holes, into which the torsion spring heads at both ends of the torsion spring are embedded. Alternatively, both the inner wall of the sleeve 433 and the outer wall of the convex cylinder 121 have limiting ribs, against which the torsion spring heads at both ends of the torsion spring rest.

[0077] For some examples, see Figure 5 The sleeve 433 includes a sleeve body 4331, a first boss 4332, and a second boss 4333. The first boss 4332 is circumferentially disposed along the inner wall of the sleeve body 4331. The first elastic member 431 is located below the first boss 4332. The second boss 4333 is circumferentially disposed along the outer wall of the sleeve body 4331. The second transmission wheel 4322 is fixed to the second boss 4333. The space below the first boss 4332 in the sleeve 433 is used to install the first elastic member 431.

[0078] For some examples, see Figure 5 The swinging mechanism 40 also includes a first bearing 44. The sleeve 433 is located on both sides of the second boss 4333 and is respectively sleeved with a first bearing 44 so that the sleeve 433 can be rotatably connected to the first support body 11; a second bearing 33 is provided between the convex cylinder 121 and the adapter shaft 41 so that the adapter shaft 41 can be rotatably connected to the second support body 12.

[0079] The first bearing 44 is located on either side of the second boss 4333 in the vertical direction. The second boss 4333 can limit the first bearing 44 in the vertical direction. The first bearing 44 is used to reduce friction when the sleeve 433 rotates relative to the first support body 11, thereby reducing structural wear, extending the service life of the sleeve 433, and improving rotation efficiency.

[0080] The second bearing 33 can be used to reduce friction when the convex cylinder 121 and the adapter shaft 41 rotate relative to each other, thereby reducing structural wear, extending the service life of the convex cylinder 121 and the adapter shaft 41, and improving rotation efficiency.

[0081] For example, both the first boss 4332 and the convex cylinder 121 have fixing holes, into which the torsion spring heads at both ends of the torsion spring are inserted. Alternatively, both the lower surface of the first boss 4332 and the outer wall of the convex cylinder 121 have limiting ribs, against which the torsion spring heads at both ends of the torsion spring abut.

[0082] For some examples, see Figure 5 The first support body 11 includes a first support shell 111 and a first bottom shell 112. The first support shell 111 has a boss 1111, and the boss 1111 has an annular groove 1111a. The first bottom shell 112 is sleeved on the outer wall of the boss 1111. The boss 1111, the first transmission wheel group 432 and the sleeve 433 are all located in the first bottom shell 112, and one end of the sleeve 433 is located in the annular groove 1111a.

[0083] The first bottom shell 112 is fixed to the bottom of the first support shell 111 and is used to mount portions of the swing mechanism 40, such as the first transmission wheel assembly 432 and the sleeve 433. The upper end of the sleeve body 4331 and the first bearing 44 disposed around the upper end of the sleeve body 4331 are positioned within the annular groove 1111a, thereby limiting the horizontal position of the upper end of the sleeve body 4331.

[0084] For example, a stepped cavity is formed within the first bottom shell 112, comprising a first stepped cavity and a second stepped cavity that are interconnected. The torsion spring is sleeved around the convex cylinder 121, the sleeve body 4331 is sleeved around the torsion spring, and the first bearing 44 is sleeved around the sleeve body 4331. The first bearing 44, located below the lower end of the sleeve body 4331 and the second boss 4333, is positioned within the second stepped cavity, while the second transmission wheel 4322 is positioned within the first stepped cavity. This improves the stability of the swinging motion of the second support body 12 and the first cleaning assembly 20.

[0085] For some examples, see Figure 2 The cleaning device 100 also includes a lifting mechanism 50, which includes a lifting drive 51, a lifting transmission member 52, a lifting main rod 53 and a lifting rocker arm 54; the lifting transmission member 52 connects the first support body 11 and the lifting main rod 53, and the adapter shaft 41 passes through the lifting main rod 53 and the lifting rocker arm 54. The lifting main rod 53 and the lifting rocker arm 54 are rotatably connected, and the lifting drive 51 is drivingly connected to the lifting transmission member 52, so that the lifting main rod 53 can drive the lifting rocker arm 54 to move up and down relative to the first support body 11.

[0086] The lifting mechanism 50 is used to lift the cleaning assembly to avoid ground objects, such as carpets, when the cleaning device is moving. The lifting main rod 53 is rotatably connected to the lifting swing rod 54, that is, when the first cleaning assembly 20 swings, the lifting swing rod 54 also swings together. Figure 3 The dotted lines show the position changes of the first cleaning assembly 20, the second support body 12 and the lifting swing rod 54 after the swing. Under the action of the lifting mechanism 50, the first cleaning assembly 20 and the second cleaning assembly 60 can be lifted and lowered together, and the first cleaning assembly 20 can rotate relative to the first support body 11 without being affected.

[0087] The lifting transmission member 52 connects the first support body 11 and the lifting main rod 53, and the lifting swing rod 54 is connected to the second support body 12. When the lifting main rod 53 drives the lifting swing rod 54 to rise or fall, the first cleaning component 20 and the second cleaning component 60 also rise or fall together.

[0088] The lifting mechanism 50 is used to drive the first cleaning assembly 20 and the second cleaning assembly 60 to rise or fall. The lifting drive 51 is used to provide power for the first cleaning assembly 20 and the second cleaning assembly 60 to rise and fall. Exemplarily, the lifting drive 51 may include a drive motor, such as an AC motor or a DC motor.

[0089] The lifting transmission member 52 is used to transmit the power of the lifting drive member 51 to the first cleaning assembly 20 and the second cleaning assembly 60. The lifting transmission member 52 is not limited to the transmission method. For example, the lifting transmission member 52 can adopt gear transmission, belt transmission, screw thread, elastic member or chain transmission, or a combination of the above methods.

[0090] For example, see Figure 2 The lifting transmission member 52 includes a lifting screw 521, and the lifting main rod 53 includes a threaded hole 53a. The lifting driving member 51 is drivingly connected to the lifting screw 521, so that the lifting screw 521 is drivingly connected to the threaded hole 53a. In this way, the structure can be made more compact and the transmission accuracy can be improved.

[0091] In some embodiments, one of the lifting main rod 53 and the first support body 11 has a guide hole 53d, and the other of the lifting main rod 53 and the first support body 11 has a guide column 113. The guide column 113 is passed through the guide hole 53d to guide the lifting movement of the lifting main rod 53, so that the lifting main rod 53 can be lifted and lowered smoothly on a predetermined trajectory.

[0092] For example, see Figure 2 The lifting main rod 53 has a guide hole 53d, and the first support body 11 has a guide column 113. The guide column 113 cooperates with the guide hole 53d to play a guiding role, so that the first support body 11 can rise or fall along the guide column 113.

[0093] In other embodiments not shown, the first support body has a guide hole, and the lifting main rod has a guide column, which is passed through the guide hole to guide the lifting movement of the lifting main rod, so that the lifting main rod can be lifted and lowered smoothly, reducing the shaking and jamming of the mechanism.

[0094] For some examples, see Figure 7 One end of one of the lifting main rod 53 and the lifting rocker rod 54 has two clamping arms 541, and the other end of the lifting main rod 53 and the lifting rocker rod 54 extends between the two clamping arms 541. The adapter shaft 41 can be slidably passed through the clamping arms 541 so that the lifting main rod 53 can drive the lifting rocker rod 54 to rise and fall along the adapter shaft 41.

[0095] For example, one end of the lifting rocker 54 has two clamping arms 541, and one end of the lifting main rod 53 extends between the two clamping arms 541. This improves the consistency and smoothness of the lifting main rod 53 during its ascent or descent. The adapter shaft 41 slides through the clamping arms 541, reducing wear between the lifting main rod 53 and the adapter shaft 41, reducing vibration and noise, and lowering energy consumption.

[0096] In some other embodiments not shown, one end of the lifting main rod has two clamping arms, and one end of the lifting rocker arm extends between the two clamping arms.

[0097] For some examples, see Figure 7 The first cleaning component 20 also includes a second elastic member 23, the lifting rocker arm 54 has a first through hole 54a, and the first output rod 22 can be lifted and lowered through the first through hole 54a; the lifting rocker arm 54 forms a first limiting groove 54b toward the first output rod 22, and the first output rod 22 forms a second limiting groove 22a toward the lifting rocker arm 54, the first limiting groove 54b and the second limiting groove 22a are surrounded to form a first limiting space, the second elastic member 23 is sleeved on the first output rod 22, and the second elastic member 23 is located in the first limiting space.

[0098] The first output rod 22 can rise or fall relative to the lifting rocker 54 along the first through hole 54a. The second elastic member 23 deforms in the vertical direction within the first confined space. For example, when encountering an obstacle or a collision, the first output rod 22 rises relative to the lifting rocker 54, and the second elastic member 23 is compressed, elastically deforming and accumulating elastic potential energy. When the external force of the obstacle disappears, the second elastic member 23 releases the elastic potential energy, causing the first output rod 22 to descend. In this way, the second elastic member 23 acts as a buffer and vibration reducer, reducing the possibility of damage to the first output rod 22 or the first cleaning member 21 when encountering obstacles or collisions. Furthermore, during cleaning operations, the second elastic member 23 applies downward pressure to the first cleaning member 21, enhancing cleaning effectiveness.

[0099] For some examples, see Figure 3 and Figure 8 The second cleaning component 60 includes a second cleaning member 61, a second output rod 62 and a third elastic member 63. The second cleaning member 61 is arranged at one end of the second output rod 62. For example, the second cleaning member 61 is detachably connected to one end of the second output rod 62. The other end of the second output rod 62 is passed through the first support body 11. The rotating transmission member 32 is connected to the second output rod 62 so that the second output rod 62 drives the second cleaning member 61 to rotate.

[0100] In some embodiments, the lifting main rod 53 has a second through hole 53b, and the second output rod 62 can be lifted and lowered through the second through hole 53b. The lifting main rod 53 forms a third limiting groove 53c toward the second output rod 62, and the second output rod 62 forms a fourth limiting groove 62a toward the lifting rocker rod 54. The third limiting groove 53c and the fourth limiting groove 62a are surrounded to form a second limiting space. The third elastic member 63 is mounted on the second output rod 62, and the third elastic member 63 is located in the second limiting space.

[0101] The second output rod 62 can rise or fall relative to the main lifting rod 53 along the second through hole 53b. The third elastic member 63 deforms in the vertical direction within the second confined space. For example, when encountering an obstacle or a collision, the second output rod 62 rises relative to the lifting rocker 54, and the third elastic member 63 is compressed, elastically deforming and accumulating elastic potential energy. When the external force of the obstacle disappears, the third elastic member 63 releases the elastic potential energy, causing the second output rod 62 to descend. In this way, the third elastic member 63 can act as a buffer and vibration reducer, reducing the possibility of damage to the second output rod 62 or the second cleaning member 61 when encountering obstacles or collisions. Furthermore, during cleaning operations, the third elastic member 63 can apply downward pressure to the second cleaning member 61, enhancing cleaning effectiveness.

[0102] For example, the second elastic member 23 may be a compression spring, a tension spring, or an elastic cord, and the third elastic member 63 may be a compression spring, a tension spring, or an elastic cord, etc. By controlling the lifting drive member 51 and adjusting the height of the lifting main rod 53 relative to the first support body 11, the downward pressure of the first cleaning member 21 and the second cleaning member 61 can be adjusted.

[0103] For some examples, see Figure 7 and Figure 8 The first cleaning component 20 also includes a first limiting cap 24, which is fixed to the upper end of the first output rod 22 and is used to limit the downward movement of the first output rod 22 relative to the lifting rocker rod 54; the second cleaning component 60 also includes a second limiting cap 64, which is fixed to the upper end of the second output rod 62 and is used to limit the downward movement of the second output rod 62 relative to the lifting main rod 53.

[0104] Exemplarily, both the first and second limiting caps 24 and 64 include a horizontal portion and a vertical portion. The vertical portion of the first limiting cap 24 is inserted into the upper end of the first output rod 22, while the vertical portion of the second limiting cap 64 is inserted into the upper end of the second output rod 62. Furthermore, the cross-section of the horizontal portion of the first limiting cap 24 is larger than the cross-section of the first through-hole 54a, while the cross-section of the horizontal portion of the second limiting cap 64 is larger than the cross-section of the second through-hole 53b, thereby achieving a limiting effect. The first and second limiting caps 24 and 64 facilitate installation of the first and second output rods 22 and 62.

[0105] In some embodiments, the rotating mechanism 30 further includes a second bearing 33, the first support body 11 includes a first support shell 111 having a first accommodating cavity 111a, the second support body 12 includes a second support shell 122 having a second accommodating cavity 122a, and the rotating transmission member 32 is located in the first accommodating cavity 111a and the second accommodating cavity 122a.

[0106] In some embodiments, the first support shell 111 has multiple first limiting cavities 111b that are connected to the first accommodating cavity 111a. The upper and lower parts of the first support shell 111 are respectively provided with two first limiting cavities 111b with corresponding positions. Each first limiting cavity 111b is provided with a second bearing 33, and the second output rod 62 and the adapter shaft 41 are respectively provided in the corresponding second bearings 33 in the upper and lower parts of the first support shell 111.

[0107] In some embodiments, the upper portion of the second support shell 122 has a second limiting cavity 122b that is connected to the second accommodating cavity 122a, and a second bearing 33 is provided in the second limiting cavity 122b. The first output rod 22 is inserted into the second bearing 33 in the upper portion of the second support shell 122.

[0108] The first limiting cavity 111b and the second limiting cavity 122b are used to install the second bearing 33. The second bearing 33 is used to reduce the friction between the adapter shaft 41 and the second output rod 62 and the first support body 11 during rotation, and to reduce the friction between the first output rod 22 and the second support body 12 during rotation, thereby reducing wear between the structures and lowering the energy consumption of the device.

[0109] In some embodiments, the rotation transmission member 32 includes a transmission wheel set.

[0110] For example, the transmission wheel assembly is composed of a plurality of transmission wheels, and the diameters of the transmission wheels can be the same or different, so that the transmission torque can be changed, so that the rotation driving member 31 can transmit the driving force to the first cleaning member 21 and / or the second cleaning member 61 through the plurality of transmission wheels. The transmission wheels can be gears or turbines.

[0111] Illustratively, the transmission wheel set includes a worm wheel and a worm, and the worm wheel and the worm wheel are meshed with each other to drive the first cleaning member 21 and / or the second cleaning member 61 to rotate to achieve cleaning.

[0112] In some embodiments, the rotating transmission member 32 includes an intermediate transmission wheel 321, a second transmission wheel group 322, a third transmission wheel group 323 and a fourth transmission wheel group 324. The intermediate transmission wheel 321, the second transmission wheel group 322 and the fourth transmission wheel group 324 are arranged in the first accommodating chamber 111a, and the second transmission wheel group 322 is arranged in the second accommodating chamber 122a; the rotating driving member 31 is driven and connected to the intermediate transmission wheel 321, the intermediate transmission wheel 321 is driven and connected to the second transmission wheel group 322, the second transmission wheel group 322 is driven and connected to the adapter shaft 41, the adapter shaft 41 is driven and connected to the third transmission wheel group 323, and the third transmission wheel group 323 is driven and connected to the first output rod 22 to drive the first cleaning member 21 to rotate; the intermediate transmission wheel 321 is driven and connected to the fourth transmission wheel group 324, and the fourth transmission wheel group 324 is driven and connected to the second output rod 62 to drive the second cleaning member 61 to rotate.

[0113] Illustratively, the rotary drive member 31 includes a drive shaft 311, which is in transmission connection with an intermediate transmission wheel 321, driving the intermediate transmission wheel 321 to rotate. This in turn drives the fourth transmission wheel assembly 324 to transmit power to the second output rod 62, causing the second output rod 62 to rotate for cleaning. Simultaneously, the intermediate transmission wheel 321 is sequentially in transmission connection with the second transmission wheel assembly 322, the adapter shaft 41, the third transmission wheel assembly 323, and the first output rod 22, causing the first output rod 22 to rotate for cleaning.

[0114] By configuring the transmission ratios among the intermediate transmission wheel 321 , the second transmission wheel set 322 , the third transmission wheel set 323 and the fourth transmission wheel set 324 , the first cleaning member 21 and the second cleaning member 61 can rotate at the same speed or at a different speed.

After power is turned on, the program can be used to control the cleaning device to automatically run a planned route for cleaning. There is no need for manual operation of the cleaning device, and it is convenient and quick to use.

Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
