Some embodiments of the present application provide a cleaning device, which includes a machine body 100, a cleaning assembly 200, a first driving assembly 300 and a second driving assembly 400; the first driving assembly 300 and the second driving assembly 400 are connected to the machine body 100, the cleaning assembly 200 includes a first roller 210, the first roller 210 is connected to the first driving assembly 300 and the second driving assembly 400, the first driving assembly 300 is used to drive the first roller 210 to rotate around its own axis to clean a surface to be cleaned, and the second driving assembly 400 is used to drive the first roller 210 to move along the axis.

[0037] Specifically, in the present application, the first driving assembly 300 is used to drive the first roller 210 to rotate around the axis, so that the first roller 210 can clean the surface to be cleaned; when some corners, edges and other hard-to-reach places need to be cleaned, the second driving assembly 400 is used to drive the first roller 210 to move along the axis, so that the first roller 210 can extend along the axis relative to the machine body 100, so that the first roller 210 can be closer to the corners and other areas to be cleaned, thereby improving the cleaning effect of the cleaning device.

[0038] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 , Figure 4 a structural view of a cleaning device provided by some embodiments of the present application, in which a first roller is in a retracted state; Figure 5 a structural view of a cleaning device provided by some embodiments of the present application, in which a first roller is in an extended state. Some embodiments of the present application provide a cleaning device, which includes a machine body 100, a cleaning assembly 200, a first driving assembly 300 and a second driving assembly 400; the first driving assembly 300 and the second driving assembly 400 are connected to the machine body 100, the cleaning assembly 200 includes a first roller 210, the first roller 210 is connected to the first driving assembly 300 and the second driving assembly 400, the first driving assembly 300 is used to drive the first roller 210 to rotate around its own axis to clean a surface to be cleaned, and the second driving assembly 400 is used to drive the first roller 210 to move along the axis. Figure 6FIG. 2 shows a second cross-sectional view of the second driving assembly cooperating with the first driving assembly in the cleaning device according to some embodiments of the present application. In some embodiments, the first driving assembly 300 includes a first driving member 310 and a first output shaft 320, the first driving member 310 is connected to the body 100, and the first output shaft 320 is in driving connection with the first driving member 310. One of the first output shaft 320 and the first roller 210 has a cooperating groove 211, and the other one of the first output shaft 320 and the first roller 210 is partially inserted into the cooperating groove 211 and abuts against the groove side wall of the cooperating groove 211. The first output shaft 320 is configured to drive the first roller 210 to rotate around the axis under the driving of the first driving member 310.

[0039] Specifically, by virtue of the one of the first output shaft 320 and the first roller 210 having the cooperating groove 211 and the other one of the first output shaft 320 and the first roller 210 being partially inserted into the cooperating groove 211 and abutting against the groove side wall of the cooperating groove 211, the first driving member 310 can drive the first roller 210 to rotate around the axis during the driving of the first output shaft 320 to rotate around the axis, thereby achieving the cleaning of the surface to be cleaned. Preferably, the first driving member 310 is an electric motor.

[0040] Referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 7 FIG. 3 shows a structure diagram of the driving member cooperating with the first output shaft in the cleaning device according to some embodiments of the present application. In some embodiments, the cooperating groove 211 is located at the first roller 210, the outer contour of the first output shaft 320 in the axial direction is circular, and the first output shaft 320 is in interference fit with the groove side wall of the cooperating groove 211.

[0041] Specifically, the inner contour shape of the cooperating groove 211 is adapted to the shape of the outer wall of the first output shaft 320, and the first output shaft 320 is in interference fit with the groove side wall of the cooperating groove 211, so that the first driving member 310 can drive the first roller 210 to rotate around the axis during the driving of the first output shaft 320 to rotate around the axis, and when the friction between the first roller 210 and the surface to be cleaned is too large, the first output shaft 320 can slip relative to the groove side wall of the cooperating groove 211, thereby avoiding damage caused by excessive load of the electric motor. In addition, the cooperating groove 211 is located at the end of the first roller 210, so that the outer circumferential surface of the first roller 210 in the axial direction is located outside the first output shaft 320, thereby increasing the contact area between the first roller 210 and the surface to be cleaned and improving the cleaning efficiency of the cleaning device.

[0042] In other embodiments, the first output shaft 320 has a non-circular outer profile in the axial direction, i.e., a special-shaped structure, such as a square shape, etc., so that the first output shaft 320 can be driven to move synchronously under the driving of the first driving member 310.

[0043] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the first output shaft 320 has a through hole 321, the axis of the through hole 321 coincides with the axis of the first output shaft 320, the second driving assembly 400 includes a second driving member 410 and a transmission member 420, the transmission member 420 is in transmission connection with the second driving member 410, the transmission member 420 passes through the through hole 321 and is connected with the first roller 210, and the transmission member 420 is configured to drive the first roller 210 to move in the axial direction under the driving of the second driving member 410.

[0044] Specifically, since the axis of the through hole 321 coincides with the axis of the first roller 210, when the second driving member 410 drives the transmission member 420 to move in the axial direction in the through hole 321, it will not interfere with the rotation of the first output shaft 320, so that the first roller 210 can be driven to rotate while moving in the axial direction, thereby ensuring the efficiency of the cleaning device. The second driving member 410 can be mounted on the machine body 100 or on the first output shaft 320, as long as it can drive the first roller 210 to move in the axial direction. It should be noted that the transmission member 420 and the first roller 210 can be directly connected or rotationally connected.

[0045] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the transmission member 420 includes a second output shaft 421 and an ejection block 422, the second output shaft 421 is in transmission connection with the second driving member 410, the ejection block 422 is sleeved on the second output shaft 421 and is in threaded connection with the second output shaft 421, the ejection block 422 is connected with the first roller 210, and the second output shaft 421 is configured to rotate around the axial direction under the driving of the second driving member 410 to drive the ejection block 422 to move in the axial direction.

[0046] Specifically, the second driving member 410 can be mounted on the machine body 100, and through the threaded connection between the ejection block 422 and the second output shaft 421, the second driving member 410 can stably drive the ejection block 422 to move through threaded transmission during the driving of the second output shaft 421 to rotate, thereby stably driving the first roller to move in the axial direction and reducing the shaking of the first roller 210, thereby ensuring the cleaning effect of the cleaning device.

[0047] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 , in some embodiments, the outer wall of the ejecting block 422 abuts against the hole wall of the through hole 321, and the outer profile of the ejecting block 422 in the axial direction is non-circular, so that the relative rotation between the ejecting block 422 and the first output shaft 320 is limited, so that the ejecting block 422 can rotate synchronously with the first output shaft 320 under the driving of the second driving member 410, to apply a torsion force to the first roller 210, so as to improve the rotation power of the first roller 210, so as to facilitate cleaning of stubborn stains, and improve the cleaning effect of the cleaning device.

[0048] When the rotation direction and speed of the second output shaft 421 are the same as those of the first output shaft 320, the ejecting block 422 and the first output shaft 320 simultaneously apply a force to the first roller 210 to drive the first roller 210 to rotate around the axial direction; when the speed of the second output shaft 421 is different from that of the first output shaft 320, the second output shaft 421 rotates relative to the first output shaft 320, and since the rotation of the ejecting block 422 is limited by the first output shaft 320, under the threaded transmission, the ejecting block 422 can move along the axial direction relative to the second output shaft 421, to drive the first roller 210 to extend or retract along the axial direction.

[0049] Referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 8 is a partially exploded structural schematic view of a transmission member and a first output shaft in a cleaning device provided by some embodiments of the present application. In some embodiments, the ejecting block 422 includes a sliding block part 423 and an ejecting part 424, the sliding block part 423 is sleeved on the second output shaft 421 and is threadedly connected with the second output shaft 421, the ejecting part 424 is connected with the first roller 210, and the ejecting part 424 has a mounting groove 425, the sliding block part 423 contains the mounting groove 425, and the outer profile of the sliding block part 423 is circular, and the sliding block part 423 is in interference fit with the groove side wall of the mounting groove 425.

[0050] Specifically, when the second output shaft 421 drives the ejecting block 422 to move to the limit position, the movement of the ejecting block 422 is limited, and by virtue of the circular outer profile of the sliding block part 423 and the interference fit between the sliding block part 423 and the groove side wall of the mounting groove 425, the sliding block part 423 can slide relative to the groove side wall of the mounting groove 425, so as to move synchronously with the second output shaft 421, thereby avoiding damage to the second driving member 410.

[0051] Referring to Figure 5 , Figure 6 , Figure 7and Figure 8 In some embodiments, the slider portion 423 comprises a worm 426 and a sliding sleeve 427, the worm 426 is threadedly connected with the second output shaft 421, the sliding sleeve 427 is sleeved on the worm 426 and connected with the worm 426, and the sliding sleeve 427 is in interference fit with the slot side wall of the mounting slot 425. By providing the sliding sleeve 427, the volume of the slider portion 423 can be reduced, thereby realizing the lightweight of the structure. Preferably, the number of the sliding sleeves 427 is two, and the two sliding sleeves 427 are respectively sleeved on the two ends of the worm 426.

[0052] Referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the through hole 321 comprises a mounting section 322 and a matching section 323 which are in communication with each other, the mounting section 322 is located at one end close to the first roller 210, and the inner contour size of the mounting section 322 in the axial direction is greater than that of the matching section 323, so that a stepped wall 324 is formed between the mounting section 322 and the matching section 323, the ejection block 422 is partially accommodated in the mounting section 322, and the side of the ejection block 422 away from the first roller 210 is used to abut against the stepped wall 324 to limit the movement of the ejection block 422 to the side close to the first output shaft 320.

[0053] Specifically, by providing the stepped wall 324 capable of abutting against the side of the ejection block 422 away from the first roller 210, the movement of the ejection block 422 to the side close to the first output shaft 320 can be limited, thereby playing a limiting role. Among them, the inner contour size of the mounting section 322 in the axial direction is greater than that of the matching section 323, so that the size of the ejection block 422 and the first output shaft 320 is adapted to the size of the first roller 210, so as to stably drive the first roller 210 to rotate.

[0054] Further, the first output shaft 320 has a boss 360, the mounting section 322 is arranged on the boss 360, and the side of the boss 360 close to the matching section 323 abuts against the machine body 100 to limit the first output shaft 320, thereby improving the installation stability of the first output shaft 320.

[0055] Still further, the cleaning device further comprises a bearing 370, the machine body 100 has a mounting hole, the first output shaft 320 is arranged through the mounting hole and abuts against the hole wall of the mounting hole through the bearing 370, so as to stably support the first output shaft 320 while reducing the interference with the rotation of the first output shaft 320. Preferably, two bearings 370 are sleeved on the first output shaft 320.

[0056] Referring to Figure 1 , Figure 5 , Figure 6 and Figure 9, Figure 9 The structural schematic diagram of the first driving assembly and the second driving assembly in the cleaning device provided for some embodiments of the present application is shown. In some embodiments, the first driving assembly 300 further comprises a first rotating gear 340, a second rotating gear 330 and a first gear module 350. The first rotating gear 340 is connected with the output end of the first driving member 310, the second rotating gear 330 is coaxially connected with the first output shaft 320, and the first gear module 350 is engaged with the first rotating gear 340 and the second rotating gear 330 to amplify the output torque of the second rotating gear 330.

[0057] Specifically, by reasonably setting the first gear module 350, the torque output by the second rotating gear 330 can be reasonably amplified, and the first output shaft 320 can stably drive the first roller 210 to rotate through the transmission of the second rotating gear 330, thereby improving the reliability of the cleaning device.

[0058] Further, the first gear module 350 comprises a first matching gear 351, a second matching gear 352 and a third matching gear 353. The first matching gear 351 is engaged with the first rotating gear 340, the radius of the first matching gear 351 is greater than that of the first rotating gear 340, the second matching gear 352 is coaxial with the first matching gear 351, and the radius of the second matching gear 352 is smaller than that of the first matching gear 351, the third matching gear 353 is engaged with the second matching gear 352 and the second rotating gear 330, and the radius of the third matching gear 353 is greater than that of the second matching gear 352.

[0059] Specifically, by engaging the first matching gear 351 with the first rotating gear 340, the radius of the first matching gear 351 is greater than that of the first rotating gear 340, so that the output torque can be amplified through the first matching gear 351, and by coaxially connecting the second matching gear 352 with the first matching gear 351, the radius of the second matching gear 352 is smaller than that of the first matching gear 351, the output torque is amplified, and by engaging the third matching gear 353 with the second matching gear 352 and the second rotating gear 330, the radius of the third matching gear 353 is greater than that of the second matching gear 352, the output torque of the second rotating gear 330 is further amplified, so that the first output shaft 320 can output a preset torque, thereby improving the reliability of the cleaning device.

[0060] The third matching gear 353 and the second matching gear 352 can be directly engaged or indirectly engaged, as long as they can increase the torque and facilitate arrangement.

[0061] Referring to Figure 1 , Figure 5 , Figure 6 and Figure 9In some embodiments, the second driving assembly 400 further comprises a first driving gear 440, a second driving gear 430 and a second gear module 450.

The second gear module 450 is engaged with the first driving gear 440 and the second driving gear 430 to amplify the output torque of the second driving gear 430.

[0062] Specifically, by reasonably setting the second gear module 450, the torque output by the second driving gear 430 can be reasonably amplified, and the transmission member 420 can stably drive the first roller 210 to rotate through the transmission of the second driving gear 430, thereby improving the reliability of the cleaning equipment.

[0063] Further, the second gear module 450 comprises a first auxiliary gear 451, a second auxiliary gear 452 and a third auxiliary gear 453.
